Both are browser form views that return 200/302 and commit, so covering both keeps the MFA-12 invariant intact. `user_setup.py` is deliberately **excluded**: it validates against the enrolling user's own in-progress secret, so a counter there would let a user lock themselves out mid-setup. ### Phase 6: Recovery Codes @@ -210,7 +243,17 @@ Plans: 4.

Any other query-string key, `ajax_load` included, is never read and never enters the hash. `ska` cannot fail on `ajax_load`. The browser test in 07-04 remains valuable for proving the overlay injects it correctly and the chain survives in practice, but the "silent signature failure" fear is unfounded. +- **Open Decision to settle here (original text, superseded by the note above):** whether `ska` tolerates the `ajax_load` parameter the overlay injects. `pb.add_ajax_load` prepends a hidden `ajax_load=` input and `pb.ajax_click` appends it to the GET.

One browser test settles it. - Also confirm in the same browser test that `common_content_filter` reaches the wrapped z3c.form — `plone.z3cform.layout`'s `wrap_form` renders inside `#content` and `el.find()` is a descendant search, so it should be reachable. - COEX-04 is the trap: `control_panel_extra.html` (`controlpanel.py:84`) and `request_bar_code_reset_email.pt` (`request_bar_code_reset.py:90`) are reached by `restrictedTraverse` and are **not** overrides. Deleting `skins/` deletes two live templates; convert both in the same commit. The email path has zero test coverage, so CI will not notice. - The vendored copies are stale and actively harmful, which is extra reason to delete rather than maintain: `popupforms.js` reverts `msieversion()` to `jQuery.browser.msie` (removed in jQuery 1.9) and drops `dl.portalMessage.warning` from `common_content_filter`, swallowing warning messages in every Plone overlay site-wide. -- **UI hint** is set because this is the one phase with real frontend surface (login overlay, resource registries, templates).

One-way: rehashing requires the plaintext codes, which are unrecoverable by design. +- [Phase ?]: [Phase 6]: 06-01: validate_second_factor (not RESEARCH.md's proposed validate_token_or_recovery_code) is the promoted dispatcher name -- the primary noun is 'second factor', and the promote was free since the dispatcher did not exist yet. validate_token stays byte-identical as the demoted TOTP variant handler. +- [Phase ?]: [Phase 6]: 06-01: recovery codes are consumed by removing the matched stored-hash entry by index (stored[:i] + stored[i+1:]), never by equality filter, so a birthday-collision duplicate hash cannot burn two codes on one use. Neither new memberdata property (salt, hashes) is declared on IEnhancedUserDataSchema -- proven by extending the existing LOCKOUT_STATE_PROPERTIES guard rather than a parallel test; both non-vacuity mutations reproduced red before being trusted. +- [Phase ?]: [Phase 6]: 06-02: RECOV-03 deliberate behaviour change -- test_handleSubmit scenario 1's redirect assertion changed from 'ends with /@@personal-information' to 'location header is None', since the success response now renders the ten codes in the same response instead of redirecting (plone.z3cform 0.8.1's FormWrapper.update() only blanks/skips render on a 302/303 status). +- [Phase ?]: [Phase 6]: 06-02: regeneration has no dedicated view -- @@setup-two-factor-authentication re-entered is the regeneration path, reusing @@show-disable-two-factor-authentication-link as available_expr rather than a fourth SettingsHelper method; the form's existing TOTP check is the anti-self-perpetuation gate (T-06-08). +- [Phase ?]: [Phase 6]: 06-03: RECOVERY_CODE_LOW_WATERMARK=3 added; validate_recovery_code's accept branch queues one warning-level IStatusMessage (mapping-based i18n substitution, not str.format) after the consume write and before return True -- unreachable from a failed or anonymous attempt by construction. A missing getRequest() degrades to silence, not a refusal. +- [Phase ?]: [Phase 6]: 06-03: extended test_no_second_factor_state_written_from_the_plugin (MFA-12) in place rather than a parallel test -- absence tuples gained both recovery-code properties and all three new helper functions; positive controls restructured into (name, source, label) triples pinned per-file. Both non-vacuity mutations (pas_plugin.py, subscribers.py) reproduced red and restored byte-identical, plus a third check confirming a wrongly-paired positive control also fails. +- [Phase ?]: [Phase 07]: 07-01: R5-vs-WR-03 test placement -- followed this repo's own WR-03 precedent (one test method per requirement, grouped by concern) over the plone-write-tests skill's R5; new COEX-01/COEX-09/BUG-01 tests landed in the existing TestTokenFormLockout class, not a second class. +- [Phase ?]: [Phase 07]: 07-01: test_next_url_is_validated_against_the_portal's second (on-site) login uses a recovery code, not a second TOTP code, because two genuine TOTP logins moments apart land in the same ~30s interval and MFA-06's replay guard would refuse the second acceptance -- a hazard the plan text did not call out, found during execution. +- [Phase ?]: [Phase 07]: 07-02: control-panel render() non-vacuity control uses super(GoogleAuthenticatorSettingsEditForm, form).render() -- the same call render() makes internally -- asserting startswith() and strict length growth, rather than a heading-only fallback. +- [Phase ?]: [Phase 07]: 07-02: Task 1/Task 2 commit boundary drifted from the plan's file split -- test_no_restrictedTraverse_left_in_browser_code and the test_resources_are_registered docstring fix landed in Task 1's commit with the rest of test_generic.py's edits, not Task 2's; content matches the plan, only the commit differs. +- [Phase ?]: [Phase 07]: 07-02: git mv leaves an empty skins/googleauthenticator_custom directory on disk after both templates are relocated -- required an explicit rm -rf before the skin-directory-absence test could pass, since os.path.exists() is True for an empty directory. +- [Phase ?]: [Phase 07]: 07-03: profiles/uninstall/skins.xml deleted in the same commit as the two new registry-uninstall files, keeping the uninstall directory from ever being empty; the synthetic collision test replays imio.dms.mail's real reposition entry via portal_javascripts.moveResourceAfter directly rather than a fabricated GenericSetup import, since _initResources dispatches that exact shape to the same tool method;

worked around in test setUp() only, no production code changed +- [Phase ?]: [Phase 08] 08-04: found the existing test_helpers.py::test_bulk_enable_reports_failure_when_seed_key_is_broken passes for the wrong reason -- its handleSave call returns early on an unrelated RequiredMissing extraction error, and its 'error' assertion reads a leftover message from an earlier call in the same test method rather than a fresh outcome; not fixed (outside this plan's file list, still passes), documented for future readers +- [Phase ?]: [Phase 08] 08-05: cleared all 500 re-measured bin/code-analysis findings (mechanical isort sweep + hand-fixed keyword spacing/unused-imports/whitespace);

Accepted; commits pass with `--no-verify`. -- **Phase 8:** expect pre-existing test failures to surface when the test-layer isolation is fixed (`plone.testing 4.1.3` has no isolation guard; some tests currently pass *because* of a state leak). Real bugs revealed, not caused. -- **Phase 8:** the post-fix coverage baseline is genuinely unknown and cannot be estimated before `[run] source` lands. The figure is expected to drop sharply; the drop is the truth. -- **Phase 8:** the corrected `bin/code-analysis` baseline is **318 findings** (not the ~40 the pre-rename `CLAUDE.md` claimed), measured in plan 01-03 (RESEARCH C-6 / Open Question 4). 184 of the 318 (58%) are `isort` findings, and the rename actively perturbs first-party import ordering. QUAL-06 must be planned against 318. +- **Phase 5 (from 04-SECURITY.md R-04-C):** do NOT attach lockout or replay state to the `send_2fa_redirect` call chain. `challenge()` and the `IPubBeforeCommit` subscriber are write-free in their own bodies, but `send_2fa_redirect` reaches `sign_user_data` → `get_or_create_secret`, which writes a memberdata seed for a 2FA-enabled user who has none. That mint is fail-closed and not attacker-reachable, so it does not reopen T-04-05 or T-04-24 — but the write-free guarantee MFA-12 inherits covers the handler bodies, not everything reachable from them. No test currently pins that branch in either direction. +- **Phase 5 (from 04-REVIEW.md WR-01/WR-02):** for a user with 2FA enabled but no stored seed, a broken or missing `IMIO_GOOGLEAUTHENTICATOR_SEED_KEY` does not raise synchronously in `authenticateCredentials` — it raises later inside `send_2fa_redirect`, giving an uncontrolled error page instead of a clean refusal. Still fail-closed, no bypass. The fix is an unconditional `check_encryption_key_is_usable()` call plus a test for the never-enrolled state. +- **Resolved in Phase 8** (kept for one cycle as a record): `bin/code-analysis` now exits 0, so the pre-commit hook passes and `--no-verify` is no longer needed. The test-layer isolation fix revealed **zero** pre-existing failures, contrary to the expectation recorded here. The post-fix coverage figure did not drop — it measured 84% before the new tests and 90% after. The lint baseline that had to be cleared was 500 findings, not the ~40 originally recorded nor the 318 measured in plan 01-03; it grew as phases 2 through 7 added test code. +- **Still true for any future lint work:** `flake8-isort` 4.0.0 reports isort findings from a diff, so the count for a file with an already-misordered import block shifts when *any* line changes — adding one no-op body line to `userdataschema.py` adds one finding by itself. Per-file before/after counts are not a reliable "did this commit add findings" signal; check the error codes instead. +- **Open, no phase assigned — a rejected recipient address crashes the bar-code reset email path.** `browser/forms/request_bar_code_reset.py:112-113` catches `SMTPRecipientsRefused` and re-raises the same exception type; the only enclosing handler catches `ValueError`, which that exception is not. The caller gets an unhandled error instead of the in-page failure message every other path in that method uses. It predates the fork (first appears in the phase 1 rename commit) and has never had a test — those lines still show as uncovered. Found by the Phase 8 code review, recorded as CR-01 in `08-REVIEW.md`. +- **Unresolved, found 2026-08-05 during Phase 7 plan 07-04 verification:** turning on the "Globally enabled" setting does not enrol users who already exist when this add-on is installed. `is_two_factor_authentication_globally_enabled` is consulted only by `userdataschema.userCreatedHandler` and by `browser/settings_helper.py` (which menu links to show); the login gate at `helpers.py:1021` and `1044` checks only each user's own `enable_two_factor_authentication` memberdata flag; and existing users are enrolled only when an administrator saves the settings control panel form (`browser/controlpanel.py` lines 125-132), never by `setuphandlers.setupVarious`. Consequence: installing this add-on into an existing `imio.dms.mail` site — the real deployment direction — leaves every existing account without a second factor, while the setting's own description says it "globally enables the two-step verification for all users" and defaults to True. Confirmed by the operator on a real two-egg environment: install order dms.mail-then-this-package left a Member unenrolled; the reverse order enrolled them. Needs a decision: enrol at install time, consult the global setting at login, or document an explicit post-install operator step. + +### Quick Tasks Completed + +| # | Description | Date | Commit | Directory | +|---|-------------|------|--------|-----------| +| 260805-f5m | Guard userCreatedHandler against absent settings records (COEX-10) | 2026-08-05 | 184f053 | [260805-f5m-guard-usercreatedhandler-against-absent-](./quick/260805-f5m-guard-usercreatedhandler-against-absent-/) | ## Deferred Items @@ -134,6 +242,6 @@ Items acknowledged and carried forward from previous milestone close: ## Session Continuity -Last session: 2026-07-30T10:12:23.316Z -Stopped at: Completed 03-03-PLAN.md -- phase 03 code-complete, ready for verification +Last session: 2026-08-06T07:24:20Z +Stopped at: Phase 8 complete and verified — milestone v1.0 ready to close (all 8 phases done) Resume file: None diff --git a/.planning/codebase/TESTING.md b/.planning/codebase/TESTING.md index 7678ff3..f03d530 100644 --- a/.planning/codebase/TESTING.md +++ b/.planning/codebase/TESTING.md @@ -1,6 +1,11 @@ # Testing Patterns **Analysis Date:** 2026-07-28 +**Corrected:** 2026-08-05 (Phase 8 plan 08-05, D-19) — package renamed to `imio.googleauthenticator`, +the test-layer install mechanism and testing layers rewritten in plans 08-02/08-03, the coverage +instrument corrected and gated in plans 08-01/08-04.

The research uses `request.get('_2fa_pending')` in both of its + examples. With that, an anonymous request to any URL carrying + `?_2fa_pending=1&_2fa_user_id=` drives the subscriber into `sign_user_data`, which mints + a validly signed `@@google-authenticator-token` URL for an arbitrary account — and, through + `get_or_create_secret`, performs an unauthenticated memberdata write on a path that commits. + Read from `request.other` only. Form data is **not** copied into `other` (there is no + `other.update(form)` anywhere in `HTTPRequest.py`), so `request.other` is the safe channel. + +There is a fourth divergence, from `04-PATTERNS.md` rather than the research: PATTERNS.md sketches +`subscribers.py` importing `sign_user_data` from `helpers` and rebuilding the URL itself. This plan +puts one shared `send_2fa_redirect(request, response)` in `pas_plugin.py` and imports it into +`subscribers.py` instead, because the cookie clear, the `ICameFrom` `next_url` append, the status +lock and the body clear+lock would otherwise be duplicated across two hooks that must not drift. +It cannot live in `helpers.py`: `adapter.py` already imports `helpers`, so importing `ICameFrom` +there would be circular. + + + +The `chosen` signal the delta detector raised (basic-auth deactivation) is settled in plan **04-02**, +which carries the `` block.

PAS itself sets + `credentials['login']` before the authenticator loop + (`PluggableAuthService.py:638`), so the `KeyError` is unreachable through `_extractUserIds` — + but a direct call is not, and with `_dont_swallow_my_exceptions = True` a `KeyError` here is an + HTTP 500 rather than a declined login. + - **First statement of the `if two_factor_authentication_enabled:` branch**: take + `delegated_credentials = dict(credentials)`, then run the existing + `for key in credentials.keys(): del credentials[key]` wipe. Everything downstream — the + delegation loop at lines 121-137 — uses `delegated_credentials`, never `credentials`. This is + ROADMAP's "move the credentials wipe to the top of the 2FA branch so it also runs on the + exception path": the wipe cannot literally precede the copy, because the delegated plugins need + the password to verify it. + - Keep the delegation loop, `reraise(authplugin)`, and the `if authorized is None: return None` + early exit exactly as they are apart from the argument swap. + - Replace lines 151-171 (the `self.REQUEST` / `response` / `setCookie` / `sign_user_data` / + `ICameFrom` / `response.redirect(signed_url, lock=1)` block) with a single + `_mark_2fa_pending(self.REQUEST, user)` call followed by `return None`. + - Move the existing "Consume the credentials..." comment up with the wipe and extend it with the + `_extractUserIds` caching note the roadmap asks for: PAS wraps the authenticator loop in + `ZCacheable_get`/`ZCacheable_set` (`PluggableAuthService.py:641-673`); Plone 4.3 associates no + cache manager with `acl_users` so `ZCacheable_getCache()` returns `None` and the loop always + runs (`OFS/Cache.py:150-168`), but a cache manager added later would serve a previously cached + *successful* result and skip this veto entirely. + + **(c) `subscribers.py` — add `redirect_pending_2fa`.** + + Module-level imports added alongside the existing ones, one symbol per line, matching the file's + flat style: `from zope.component import adapter`, `from ZPublisher.interfaces import + IPubBeforeCommit`, `from imio.googleauthenticator.pas_plugin import REQUEST_KEY_PENDING`, `from + imio.googleauthenticator.pas_plugin import send_2fa_redirect`. Extend the module docstring — it + currently describes only the SEC-08 handler — so it names both handlers. + + The handler itself is `@adapter(IPubBeforeCommit)` on `def redirect_pending_2fa(event):`. Body: + read `request = event.request`; return immediately unless + `request.other.get(REQUEST_KEY_PENDING)`; otherwise call `send_2fa_redirect(request, + request.response)`. Nothing else — no logging of the user id, no state write. + + Its docstring must record four things, in the density of `on_process_starting`'s: that + `IPubBeforeCommit` fires after `mapply()` has already called `response.setBody(result)` and before + `transactions_manager.commit()` (`ZPublisher/Publish.py:134-146`), which is why it is the only hook + that can intervene on a login POST that never raises; that the read is from `request.other` and + never `request.get`, with the reason; that `sign_user_data` reaches `get_or_create_secret`, which + writes memberdata only for a 2FA-enabled user who somehow has no seed — pre-existing behaviour + relocated, not introduced, and fail-closed either way because a discarded mint yields a signature + the token form then rejects; and that the handler performs no other write, because Phase 5's + MFA-12 depends on it. + + **(d) `configure.zcml` — register it.** + + Append after the `IProcessStarting` block (lines 69-73), same indentation, same comment style: + a `` comment and a `` + element.

Class docstring states the WR-03 divergence from skill rule R5. Three methods: + + - `test_no_body_leak_on_2fa_redirect` (MFA-02). Build a **real** + `ZPublisher.HTTPResponse.HTTPResponse()` — the exact class the publisher uses, not a stub — and + seed it the way `mapply` would: `response.setBody('SECRET-PAGE-MARKER')`, + then assert the marker really is in `response.body` (non-vacuity control: if the seeding silently + failed, everything below passes for the wrong reason). Bind the layer request with + `setRequest`, enable 2FA on `TEST_USER_NAME` and call `_mark_2fa_pending`, then invoke the + handler with a tiny module-level event stub exposing `.request` (same spirit as + `test_subscribers.py`'s `_StubLogger`). Assert: `response.body == ''`; the marker is absent; + `response.getHeader('content-length') == '0'`; `response.status == 302`; + `'@@google-authenticator-token' in response.getHeader('Location')`. Then prove the lock holds — + call `response.setBody('REFILL')` directly, as `plone.transformchain` would, and + assert `response.body` is still `''`. Finally, the regression control for the research's + mistake: assert that a freshly built `HTTPResponse` seeded with a body and then given + `setBody('')` **still has that body**, so the reason the production code does not use + `setBody('')` is recorded as an executable fact rather than a comment. + - `test_pub_before_commit_fires_on_login_post` (COEX-08, login-POST half). The real HTTP path: + enable 2FA on `TEST_USER_NAME` (`login()` + `setMemberProperties` + `get_or_create_secret(user, + overwrite=True)`, committed the way `test_pas_plugin.py` does it), then `_get_browser()` and + `_login_browser(browser, TEST_USER_NAME, TEST_USER_PASSWORD)`. Redirect-following is fine here — + assert the browser ends on the token form: `'@@google-authenticator-token' in browser.url` and + `'auth_user=' in browser.url` and a signature parameter is present. This is the assertion that + settles Open Question 1 as 302-to-token-form. + - `test_request_flag_cannot_be_forged_from_the_query_string` (T-04-04).

But the plan's own acceptance criteria require `tests/test_pas_plugin.py::test_login_is_refused_when_seed_key_is_broken` (a pre-existing Phase 3 test, not in this plan's `files_modified`) to keep passing **unmodified**, and that test asserts a broken encryption key raises `ValueError` out of a raw `self.pas._extractUserIds(...)` call -- which never reaches `IPubBeforeCommit` and so never reaches the deferred `send_2fa_redirect`. Reconciled by adding one line, `get_secret(user)`, right before `_mark_2fa_pending`: it is a pure read (never `get_or_create_secret`, which can generate-and-write for a never-enrolled user), so it does not violate the "no ZODB write" prohibition in the common case, but it does force the same `decrypt_seed` raise synchronously that the old code produced via `sign_user_data`. Documented in `pas_plugin.py`'s inline comment. +- **Task 2's over-HTTP idiom submits via `Browser.open()` with encoded POST data, not `Browser.getControl(...).click()`.** The plan's suggested `set_handle_redirect(False)` + `raiseHttpErrors = False` combination only works against `Browser.open()`; `_clickSubmit()` (`zope/testbrowser/browser.py:407-424`) re-raises any `mechanize.HTTPError` unconditionally and never consults `raiseHttpErrors` at all, so the originally-planned clicked-control idiom raised `HTTPError: HTTP Error 302: Moved Temporarily` regardless of the two switches. Submitting the same `__ac_name`/`__ac_password`/`submit` fields as a `urllib.urlencode`d POST body through `Browser.open()` instead routes through the code path that actually honours `raiseHttpErrors`, and the test passes. +- **Test-pollution cleanup added to `TestPubBeforeCommitRedirect.tearDown`.** `_enable_2fa()` needs an explicit `transaction.commit()` so a subsequent `Browser.open()` (which calls `transactions_manager.begin()`, implicitly discarding this test method's own uncommitted memberdata write) can see the 2FA flag. That same commit-and-survive behaviour meant the flag and the encrypted secret (bound to this test module's own, later-discarded, seed-key env var) leaked into `test_generic.py::test_user_setup_view` and `test_token_view`, which log in as the same `TEST_USER_NAME` without resetting either -- surfacing as `ValueError: Ciphertext failed to decrypt`.

The actual root cause was unrelated: `Browser.open()` starts a fresh ZPublisher transaction, silently discarding the test method's own uncommitted `enable_two_factor_authentication` write from the same test.

Same end state today, + but it says what it means and stops depending on our plugin having been the most recently appended + entry. + + Split the idempotency guard so ordering is re-asserted on reinstall. Today `installed = + pas.objectIds()` / `if pluginid in installed: return PAS_TITLE + " already installed."` short-circuits + the *entire* function, so on a second profile application neither `activatePlugin` nor the ordering + call runs at all — which means re-applying the profile is not a recovery for a plugin that some + other add-on has since bumped off index 0. Restructure so the guard covers only object creation: + create the plugin object with `_setObject` only when `pluginid not in pas.objectIds()`, then always + fetch the acquisition-wrapped `plugin = pas[pluginid]` and always run the + `for info in pas.plugins.listPluginTypeInfo():` loop. Inside the loop, guard the activation + separately — `if plugin.getId() not in pas.plugins.listPluginIds(interface): + pas.plugins.activatePlugin(...)` — because `activatePlugin` raises `KeyError: 'Duplicate plugin id'` + for an already-active plugin, and then call `movePluginsTop` unconditionally. `movePluginsTop` is + idempotent for an already-first plugin (`ids.insert(0, ids.pop(0))`) and raises `ValueError` for an + inactive one, which is exactly why the activation guard has to come first. + + Keep the `if not interface.providedBy(plugin): continue` filter, the surrounding loop, and the + function's existing return-a-string behaviour (nothing consumes the return value, but do not churn + it). Add a short comment above the `movePluginsTop` call recording *why* index 0 is the security + control, citing `PluggableAuthService.py:648-667`: the same dict object is handed to every + authenticator in listing order with no break on success, so the in-place wipe reaches only the + plugins listed after ours. + + **(b) Three new test methods in `tests/test_setuphandlers.py`.** + + Add `self.pas = getToolByName(self.portal, 'acl_users')` to `setUp`, and the + `IAuthenticationPlugin` import at module level. + + - `test_plugin_is_first_authenticator` (MFA-03). Assert + `self.pas.plugins.listPlugins(IAuthenticationPlugin)[0][0] == PAS_ID`. The docstring carries the + weight here and must say three things an operator cannot get anywhere else: that this assertion + *is* the security control because the failure mode is silent (at index 1, `source_users` + authenticates before the wipe reaches it, with no error page and no log line); that nothing at + request time re-asserts the position, so a later add-on calling `movePluginsTop` for its own + plugin silently displaces us; and that re-applying `imio.googleauthenticator:default` is the + recovery. Import `PAS_ID` from `imio.googleauthenticator.setuphandlers`. + - `test_reapply_profile_keeps_plugin_first_and_unique` (MFA-03, adjacency + empty probe rows). + Call `applyProfile(self.portal, 'imio.googleauthenticator:default')` a second time and assert it + does not raise, that `PAS_ID` appears in `self.pas.plugins.listPluginIds(IAuthenticationPlugin)` + exactly once (`.count(PAS_ID) == 1` — the duplicate-activation failure), and that index 0 is + still `PAS_ID`. Then the case that actually exercises the restructure: displace the plugin + deliberately with `self.pas.plugins.movePluginsDown(IAuthenticationPlugin, [PAS_ID])`, assert it + is no longer first (non-vacuity control — if the displacement silently failed, the recovery + assertion below would pass for the wrong reason), re-apply the profile, and assert it is first + again. That last pair is the whole point of splitting the guard; without it the restructure has + no test. + - `test_plugin_declares_no_challenge_protocol` (Open Question 3). Assert + `hasattr(self.pas[PAS_ID], 'protocol')` is false. Docstring: PAS resolves a challenger's protocol + with `getattr(challenger, 'protocol', challenger_id)` (`PluggableAuthService.py:1173`), so an + unset attribute keeps this challenger in a protocol group of its own — `HTTPBasicAuthHelper` is + the plugin that *does* declare `protocol = "http"`, and PAS's + `IChallengeProtocolChooser`/`IRequestTypeSniffer` machinery routes WebDAV/FTP/XML-RPC request + types to that group, which would hand those clients an HTML redirect instead of a clean 401.

Record the observed failure message in the summary. A test that + passes against both the old and the new `_add_plugin` proves nothing about the change. + + + + Ordering is set by `movePluginsTop`, is re-asserted every time the profile is applied, survives a + deliberate displacement followed by a reinstall, and has three assertions in CI. The plugin + declares no `protocol`, and a test says so. + + + + + The code change is a one-line revert, but the reversal is not what + makes this costly: the failure mode is an unenumerated external consumer — a cron job, a WebDAV + mount, an XML-RPC integration — that stops working with **no signal in this repository**, is + attributed to something else, and is reported days later. Reversal requires an incident and a + production deploy rather than a red test. Treated as one-way for gating purposes; the honest + code-level rating is `costly`. + + + Should the `credentials_basic_auth` extractor be deactivated site-wide on `acl_users` as + defence in depth, in addition to the `movePluginsTop` ordering fix from Task 1? + + + + ROADMAP.md lists this as one of four Open Decisions for the whole milestone, to be settled in this + phase "with evidence rather than assumed". Here is the evidence, all of it. + + **Why it is even on the table.** The ordering fix from Task 1 is correct but order-*dependent*. Our + veto works by emptying the shared `credentials` dict, which only blinds authenticators listed + *after* us. Any future add-on install, ZMI plugin-list edit, or third-party profile that calls + `movePluginsTop` for its own plugin puts us at index 1 and reopens the bypass — silently, with no + error page and no log line. Deactivating the Basic Auth extractor removes one whole credentials + path structurally, independent of order. + + **What the research found (04-RESEARCH.md Summary, Assumptions Log A1).** Three sibling repos were + grepped — `imio.dms.mail`, `server.dmsmail`, `industrialisation` — and turned up **no live + dependency** on HTTP Basic Auth against this Plone site's own `acl_users`: + + - `server.dmsmail`'s only `webdav-address` setting is commented out in every buildout config found. + - No XML-RPC client targeting the site was found. + - `scripts/run-copy-missing-blobs.py` does use Basic Auth with `requests`, but authenticates + *outward* to a different remote source site, not into this one. + - `pack_zeo.sh` (from `industrialisation`) does Basic-Auth into this Zope process, but targets + `/Control_Panel/Database/.../manage_pack` — the **Zope root** `Control_Panel`, which sits above + any Plone site's `acl_users`. It is unaffected either way, and it is exactly the DOC-01 + "architecturally out of reach" boundary. PAS reinforces this: `_extractUserIds` runs + `_tryEmergencyUserAuthentication` before the authenticator loop and again at the end, with the + comment "Emergency user via HTTP basic auth always wins". + + **The gap in that evidence.** The search covered three repositories, not every iMio repository. + A1 says so explicitly and rates it strong-but-not-exhaustive. No test can prove the absence of an + external consumer. + + **A cost the research did not name.** Deactivating a plugin this package does not own is a + site-wide mutation of shared state with no uninstall counterpart. That is structurally the same + anti-pattern the ROADMAP condemns for Phase 7 (`popupforms.js`'s `remove="True"` line — + "a global mutation with no uninstall counterpart, and it is why the collision flips on install + order"). Choosing (A) therefore also incurs a `profiles/uninstall/` obligation, which Phase 7 owns. + + **What is *not* at stake.** This does not affect the ordering fix, which lands either way, and it + does not affect the veto's correctness on the Basic Auth path — plan 04-03 asserts that veto + independently of whether the extractor is registered. + + + + + + + + + Select: deactivate, keep, or defer. If `deactivate`, also state whether the + `profiles/uninstall/` counterpart lands in this phase or is handed to Phase 7. + + + + Task 3: Implement the recorded choice, whichever it is + + + src/imio/googleauthenticator/setuphandlers.py, + src/imio/googleauthenticator/tests/test_setuphandlers.py + + + + - `src/imio/googleauthenticator/setuphandlers.py` as left by Task 1 — in particular + `_setup_secret_key` (lines 13-31), the model for "one focused helper called once from + `setupVarious`", and `setupVarious`'s marker-file guard. + - `src/imio/googleauthenticator/tests/test_setuphandlers.py` as left by Task 1. + - `/srv/cache/eggs/Products.PluggableAuthService-1.11.3-py2.7-linux-x86_64.egg/Products/PluggableAuthService/PluginRegistry/…` + — specifically `deactivatePlugin` (`PluginRegistry.py:153-164`), which raises + `KeyError: 'Invalid plugin id'` when the id is not currently active for that type. Any + deactivation must be guarded by `listPluginIds` for the same reason `activatePlugin` is. + - `/srv/cache/eggs/Products.PluggableAuthService-1.11.3-py2.7-linux-x86_64.egg/Products/PluggableAuthService/plugins/HTTPBasicAuthHelper.py` + — which plugin interfaces `credentials_basic_auth` is registered for, and its + `protocol = "http"` at line 64. + - The checkpoint decision recorded in Task 2, verbatim. + + + + Branch on the recorded decision. Do not re-litigate it; do not pick the other branch because it + looks tidier. + + **If the decision was `deactivate`:** add `_deactivate_basic_auth(pas)` as a new module-level + helper in `setuphandlers.py`, called from `setupVarious` after `_add_plugin(pas)` — a separate + helper, mirroring `_setup_secret_key`, not folded into `_add_plugin`, which is about our own + plugin. It deactivates `credentials_basic_auth` for `IExtractionPlugin` only, guarded by + `if 'credentials_basic_auth' in pas.plugins.listPluginIds(IExtractionPlugin):` so that a second + profile application does not raise `KeyError: 'Invalid plugin id'`. While writing it, record in + the docstring which other plugin types `credentials_basic_auth` is still active for (read + `pas.plugins.listPluginIds(...)` for each type in `listPluginTypeInfo()` on a live instance or in a + scratch test) — leaving its `IChallengePlugin` registration active while removing extraction means + browsers may still be prompted for credentials that can no longer authenticate, and an operator + needs that stated somewhere. Add `test_basic_auth_extractor_is_deactivated` asserting + `'credentials_basic_auth' not in pas.plugins.listPluginIds(IExtractionPlugin)` after install, and + extend `test_reapply_profile_keeps_plugin_first_and_unique` (or add a sibling) to prove a second + `applyProfile` does not raise. Also note, in the helper's docstring and in the summary, whether the + `profiles/uninstall/` counterpart lands here or was handed to Phase 7 per the checkpoint answer. + + **If the decision was `keep` or `defer`:** write no deactivation code. Instead make the decision + visible in the repository, because an unrecorded "we thought about it and said no" is + indistinguishable from never having thought about it. Add a comment block above `_add_plugin` in + `setuphandlers.py` stating: that `credentials_basic_auth` is deliberately left active; the date and + the three repositories the evidence covered; that the veto on that path is asserted by + `tests/test_pas_plugin.py::test_basic_auth_veto` (plan 04-03) rather than by removing the + extractor; and — this is the load-bearing part — that the ordering assertion + `test_plugin_is_first_authenticator` is therefore the only thing standing between a plugin reorder + and a Basic Auth bypass, so it must never be weakened or deleted. For `defer`, additionally name + the precondition that would flip the decision (ops owners confirm no consumer) so the follow-up has + a trigger rather than a wish. + + In **both** branches: the decision, its rationale, and its date go into `04-02-SUMMARY.md`, and + plan 04-04 reads that summary to write DOC-02. Whichever branch is taken, plan 04-03's + `test_basic_auth_veto` must remain non-vacuous — flag in the summary if `deactivate` was chosen, so + 04-03 knows to assert the veto by direct `authenticateCredentials` call rather than through + `_extractUserIds` (with the extractor gone, `_extractUserIds` produces no credentials at all and + the assertion would pass for the wrong reason). + + + + bin/test -t '!robot' + + + + - `bin/test -t '!robot'` exits 0. + - Exactly one of these holds, matching the recorded decision: + - `deactivate`: `bin/test -t test_basic_auth_extractor_is_deactivated` exits 0, and + `grep -c "_deactivate_basic_auth" src/imio/googleauthenticator/setuphandlers.py` returns `2` + (the definition and the call from `setupVarious`). + - `keep` / `defer`: `grep -c "_deactivate_basic_auth" src/imio/googleauthenticator/setuphandlers.py` + returns `0`, and `grep -c "credentials_basic_auth" src/imio/googleauthenticator/setuphandlers.py` + returns at least `1` (the recorded-decision comment). + - `04-02-SUMMARY.md` contains the literal decision id (`deactivate`, `keep` or `defer`), the + date, and the three repository names the evidence covered. + - `04-02-SUMMARY.md` states explicitly whether plan 04-03's `test_basic_auth_veto` must be + written against `_extractUserIds` or against a direct `authenticateCredentials` call. + - No file outside `files_modified` is touched.

This makes reinstalling the profile a real recovery if a third-party add-on has displaced the plugin from index 0. +- Three new tests in `test_setuphandlers.py`: `test_plugin_is_first_authenticator` (the security control itself), `test_reapply_profile_keeps_plugin_first_and_unique` (proves the re-assert path survives a deliberate displacement + reinstall, and does not raise or duplicate on a second `applyProfile`), and `test_plugin_declares_no_challenge_protocol` (Open Question 3 — asserts the plugin has no `protocol` attribute, keeping it out of `HTTPBasicAuthHelper`'s protocol group). +- The ROADMAP's open `credentials_basic_auth` decision is settled: **keep it active**.

No live dependency on HTTP Basic Auth against this Plone site's own `acl_users` was found — `server.dmsmail`'s only `webdav-address` setting is commented out everywhere it appears; no XML-RPC client targeting the site was found; `scripts/run-copy-missing-blobs.py` authenticates *outward* to a different remote site, not into this one; and `pack_zeo.sh` (from `industrialisation`) targets the Zope-root `Control_Panel`, above any Plone site's `acl_users`, so it is unaffected either way. +- **The gap, stated explicitly:** the search covered three repositories, not every iMio repository, and no test can prove the absence of an external consumer. That gap is the reason the "keep" option's stated cost — correctness depending on plugin ordering, enforced only in CI and not at request time — was accepted rather than eliminated. +- **Rationale for "keep" over "deactivate":** deactivating a plugin this package does not own is a site-wide mutation with no uninstall counterpart, structurally the same anti-pattern the ROADMAP condemns for `popupforms.js` in Phase 7. Choosing it would have incurred a `profiles/uninstall/` obligation for a hardening whose necessity the evidence could not confirm. +- **What "keep" does NOT give up:** the Basic Auth credentials path is still vetoed. Plan 04-03's `test_basic_auth_veto` asserts that directly. No global mutation occurs, no uninstall obligation is owed by this plan or by Phase 7. +- **Load-bearing consequence, stated in both the code comment and here:** `test_plugin_is_first_authenticator` is now the *only* thing standing between a future plugin reorder and a Basic Auth bypass. It must never be weakened or deleted. + +**Guidance for plan 04-03 (`test_basic_auth_veto`):** write it asserting the veto through the normal `_extractUserIds()` path — `credentials_basic_auth` remains registered and active, so the extractor still produces a credentials dict that this plugin's in-place wipe (per `authenticateCredentials`) must blind. Do **not** write it as a direct `authenticateCredentials` call that bypasses extraction; that concern only applied under the (unselected) `deactivate` branch, where `_extractUserIds` would produce no credentials at all and a veto assertion would pass for the wrong, vacuous reason. + +## Deviations from Plan + +None - Task 3 executed exactly as the plan's "keep"/"defer" branch specifies: no deactivation code, a comment block recording the decision, date, repositories, veto-test pointer, and the load-bearing consequence for the ordering test. + +## Issues Encountered + +None.

The method is two statements, reuses 04-01's shared redirect builder verbatim, and is proven write-free by `test_challenge_writes_nothing` (a memberdata property is read before and after the call and compared). +- Open Question 3 (does challenger ordering need an explicit fix?) is answered empirically as **not needed**: 04-02's `_add_plugin` already calls `movePluginsTop` unconditionally for every interface `listPluginTypeInfo()` lists that `providedBy(plugin)` is true for. Since this plan's `classImplements` addition makes `IChallengePlugin` one of those interfaces, the existing loop puts `google_auth` first among `IChallengePlugin` with zero new code -- confirmed both by `test_challenge_fires_on_unauthorized` landing on the token form (not `credentials_cookie_auth`'s `require_login`) and by a one-off `listPlugins(IChallengePlugin)` inspection during development: `[('google_auth', ...), ('credentials_cookie_auth', ...), ('credentials_basic_auth', ...)]`. +- Five new veto assertions in `tests/test_pas_plugin.py`, one per credentials-extractor path plus the exception-path guarantee, each with a disabled-2FA non-vacuity control where the assertion is an absence, and each (where applicable) proven load-bearing by a recorded, reverted mutation check rather than trusted on a green run alone. +- Discovered and documented (not fixed, since it is by design): HTTP Basic Auth is a genuine dead end for a 2FA-enabled user with this architecture -- a real client resends the same `Authorization` header on every request in the realm, including the redirect target, which re-triggers the veto and loops forever. This is an accepted consequence of 04-02's "keep `credentials_basic_auth` active" decision (T-04-20), not a new bug; `test_challenge_fires_on_unauthorized` deliberately does not follow the redirect for this reason, and the finding is recorded in this summary's key-decisions so it is not silently relied upon or silently "fixed" by a future phase without re-reading this note. + +## Task Commits + +Each task was committed atomically: + +1. **Task 1: IChallengePlugin.challenge -- the Unauthorized path, write-free, status-locked** - `2ab4998` (feat) +2. **Task 2: One veto assertion per extractor, plus the exception path** - `5161203` (test) + +**Plan metadata:** (this commit, docs: complete plan) + +## Files Created/Modified + +- `src/imio/googleauthenticator/pas_plugin.py` -- Added `IChallengePlugin` import, extended `classImplements` to declare it, added `challenge(self, request, response)`; updated the `_dont_swallow_my_exceptions` comment now that Phase 4's boundary rework (04-01's decide-only split plus this plan's `challenge()`) is complete. +- `src/imio/googleauthenticator/tests/test_challenge.py` -- Added `test_challenge_declines_without_the_flag`, `test_challenge_writes_nothing`, `test_challenge_fires_on_unauthorized` to `TestPubBeforeCommitRedirect`; added `base64`, `Browser`, `PAS_ID` imports. +- `src/imio/googleauthenticator/tests/test_pas_plugin.py` -- Added `test_form_post_veto`, `test_basic_auth_veto`, `test_both_extractors_at_once_grant_no_session`, `test_empty_credentials_do_not_raise`, `test_exception_path_still_wipes_credentials` to `TestPas`; added module-level `import base64`. + +## Decisions Made + +- **Open Question 3: no new ordering code.** See key-decisions above -- 04-02's existing generic `movePluginsTop` loop already covers `IChallengePlugin` once `classImplements` declares it, verified two ways rather than assumed. +- **`test_basic_auth_veto` asserts through `_extractUserIds`**, per 04-02-SUMMARY.md's explicit instruction (the extractor stays active under the "keep" decision), not through a direct `authenticateCredentials` call that would bypass the real entry point and prove nothing about it. +- **`test_challenge_fires_on_unauthorized` targets `/@@personal-information`** (permission `cmf.SetOwnProperties`), the same protected view `tests/test_user_setup.py` already relies on for its own redirect assertions -- reusing an already-validated "genuinely requires login" fixture rather than inventing a new one. +- **The anonymous non-vacuity control asserts `require_login` in the URL, not `login_form`.** The read_first notes named `login_path = 'login_form'` as the eventual destination, but the actually-observed intermediate landing page for an anonymous `Unauthorized` in this fixture is `credentials_cookie_auth/require_login`. The docstring and assertion were corrected against the real observed behaviour rather than left matching the plan's untested assumption. +- **The redirect is not followed to the token form in the main test.** See "Discovered" above -- following it with the same Basic Auth header present produces an infinite redirect loop by design, not by bug. The test asserts the single hop (`302`, `Location` containing `@@google-authenticator-token` and `auth_user=`, empty body) instead. +- **`test_exception_path_still_wipes_credentials`'s injection point is `pas_plugin._mark_2fa_pending`**, per the plan's explicit instruction. Documented precisely in the test's docstring and here that the corresponding mutation check (moving the wipe "below the delegation loop") was performed by relocating the wipe to directly after the `_mark_2fa_pending` call site specifically -- the minimal relocation that this particular injection point can actually detect -- not to an arbitrary point between the delegation loop and `get_secret`, which this test's injection point would not catch. This is recorded so the mutation check is not later mis-cited as proving a broader claim than it does. + +## Deviations from Plan + +### Auto-fixed Issues + +**1.

The actual observed URL after an anonymous `Unauthorized` on `/@@personal-information` is `.../acl_users/credentials_cookie_auth/require_login?came_from=...` -- `require_login` is itself a distinct, un-redirected landing page in this fixture, not a mid-flight hop to `login_form`. +- **Fix:** Assertion corrected to check for `require_login` (and that `Personal Information` is absent from the anonymous response), matching the real observed behaviour. +- **Files modified:** `src/imio/googleauthenticator/tests/test_challenge.py` +- **Verification:** `bin/test -t test_challenge_fires_on_unauthorized` passes +- **Committed in:** `2ab4998` (Task 1 commit) + +**2. [Rule 1 - Bug in test design] Following the redirect with a persistent Basic Auth header loops forever** +- **Found during:** Task 1, writing `test_challenge_fires_on_unauthorized` +- **Issue:** The first draft of the test opened the protected URL with a Basic Auth header and let `zope.testbrowser` auto-follow the resulting redirect, expecting to land cleanly on the rendered token form. Instead, `mechanize` raised `HTTPError: HTTP Error 302: ... would lead to an infinite loop` -- confirmed (with `handleErrors=False`, ruling out a swallowed Python exception) that the *second* hop is also a clean, application-level 302 back to the same signed URL: the token-form request itself still carries the same `Authorization` header, so `authenticateCredentials` sets the pending flag again on that request too, and 04-01's `IPubBeforeCommit` subscriber (which fires on *every* request with the flag set, not only login-form POSTs) redirects again. +- **Fix:** Disabled auto-redirect-following (`browser.mech_browser.set_handle_redirect(False)`) and asserted only the single hop: status `302`, `Location` containing `@@google-authenticator-token` and `auth_user=`, and an empty body. Documented as an accepted, by-design consequence of keeping `credentials_basic_auth` active (04-02, T-04-20), not a bug to fix in this plan. +- **Files modified:** `src/imio/googleauthenticator/tests/test_challenge.py` +- **Verification:** `bin/test -t test_challenge_fires_on_unauthorized` passes; full suite green +- **Committed in:** `2ab4998` (Task 1 commit) + +--- + +**Total deviations:** 2 auto-fixed (both test-correctness fixes against real observed behaviour; no production-code bug found or fixed by either). +**Impact on plan:** Both necessary for a genuinely green, honest `test_challenge_fires_on_unauthorized`.

Four paragraphs: + + 1. *The unconditional part, first, because it is the part that surprises people.* A human account + with two-step verification enabled cannot be used over HTTP Basic Auth, WebDAV, FTP or XML-RPC, + no matter how the site is configured — those protocols have nowhere to enter a six-digit code. + This follows from the second factor itself, not from any setting. + 2. *The settled decision.* State which way plan 04-02's checkpoint went, dated, with the evidence + summarised in two or three sentences: the three repositories searched (`imio.dms.mail`, + `server.dmsmail`, `industrialisation`), what was found (`webdav-address` commented out + everywhere, no XML-RPC client, the one Basic-Auth script authenticating outward to a different + site, and `pack_zeo.sh` targeting the Zope root `Control_Panel` and therefore unaffected), and + the explicit caveat that the search was not exhaustive across every iMio repository. If the + decision was `deactivate`, say plainly that Basic Auth no longer authenticates against this + site's `acl_users` for **any** user, 2FA-enabled or not, and how to reverse it. If it was `keep` + or `defer`, say that the extractor is still active and that the protection on that path is the + plugin's position at index 0 among `IAuthenticationPlugin` — with the pointer that re-applying + the add-on's profile restores that position if anything displaces it. + 3. *The supported alternative,* named concretely because a vague one is worse than none: a + dedicated service account with `enable_two_factor_authentication` left false, combined with a + source-IP restriction through the existing `ip_addresses_whitelist` control-panel setting (CIDR + notation supported), which `authenticateCredentials` checks before anything else. Cross- + reference the existing "White-listed IP addresses or IP ranges" section rather than restating + it. + 4. *What to check before deploying.* One short paragraph pointing at `04-VALIDATION.md`'s + Manual-Only row in operator terms: confirm with the ops owners that no cron job, script or + integration authenticates against this site's `acl_users` over Basic Auth. No test can prove the + absence of an external consumer. + + **(c) Reconcile the existing "ZMI -> acl_users" section (lines 196-206).** + + It currently tells an operator to make sure the Authentication list has `google_auth` first, + phrased as a manual install step. Since plan 04-02 that ordering is set by the profile with + `movePluginsTop` and re-asserted on every re-application. Rewrite the section as a verification + step and a recovery: the profile sets this; here is how to confirm it in the ZMI; if it is ever + wrong — because another add-on reordered the list — re-apply the `imio.googleauthenticator:default` + profile rather than hand-editing, because the profile is now the authoritative source. Keep the + ordered example list, keep the "critical!" emphasis, and add one sentence on why it is critical: + the plugin's credentials wipe only blinds authenticators listed after it. Do not delete the + section — an operator who finds a wrong order needs it. + + **(d) Two test methods in `tests/test_generic.py`.** + + Module-level `import os` and `import imio.googleauthenticator` if not already present (they are + currently method-local in the DOC-03 test; adding them at module level is fine and does not require + touching that test). Factor the README-reading three lines into a small helper on the class or a + module-level function if that reads better than repeating it three times — executor's call, but do + not restructure the existing DOC-03 test to use it, since that would mix an unrelated change into + this diff. + + - `test_readme_documents_zope_root_limitation` (DOC-01). Assert the presence of the facts, each + with its own failure message: `Control_Panel`, `acl_users`, `inituser`, and a string capturing + the emergency-user carve-out (`emergency user`, matched case-insensitively so a sentence-initial + capital does not break it). Docstring: what this catches is not deletion of the README but a + rewrite that drops the operator-facing scope statement while DOC-01 stays marked Complete — + phase 3's DOC-03 test is the precedent and the reasoning is identical. + - `test_readme_documents_basic_auth_consequence` (DOC-02). Assert: `credentials_basic_auth`; + `WebDAV`; `XML-RPC`; `ip_addresses_whitelist`; and `enable_two_factor_authentication` (the + service-account mechanism). Add one branch-specific fact from `04-02-SUMMARY.md` — for + `deactivate`, that the README says Basic Auth no longer authenticates against this site; for + `keep`/`defer`, that it names the index-0 ordering as what protects that path. Docstring: name + the branch the assertions were written against, so a later reversal of the decision produces a + red test rather than a stale README. + + **Do not** assert on sentences. Every fact above is an identifier or a protocol name that survives + any rewrite that keeps the information. + + + + bin/test -t test_readme_documents_zope_root_limitation -t test_readme_documents_basic_auth_consequence + bin/test -t '!robot' + + + + - `bin/test -t test_readme_documents_zope_root_limitation` exits 0. + - `bin/test -t test_readme_documents_basic_auth_consequence` exits 0. + - `bin/test -t '!robot'` exits 0 — including the pre-existing + `test_readme_documents_the_deployment_key_and_its_failure_mode`, which must still pass: the new + sections are additions, and none of DOC-03's facts may be displaced. + - `grep -c "Control_Panel" README.rst`, `grep -c "inituser" README.rst`, + `grep -ci "emergency user" README.rst`, `grep -c "credentials_basic_auth" README.rst`, + `grep -c "WebDAV" README.rst`, `grep -c "XML-RPC" README.rst` each return at least `1`. + - `python -c "import docutils.core,sys; docutils.core.publish_doctree(open('README.rst').read())"` + produces no `SEVERE`/`ERROR` output — the file is still valid reStructuredText and will still + render on PyPI.

One bullet each, in + operator-facing language rather than requirement ids: + + - The refusal no longer serves a response body. Previously a 2FA-gated request returned a 302 whose + body still contained the rendered page, readable by any client that does not follow redirects. + - The redirect moved out of the PAS plugin into an `IPubBeforeCommit` subscriber and an + `IChallengePlugin`, so it now fires on both the login-form POST (which returns 200 and never + raises) and on requests that end in `Unauthorized`. Note the plugin no longer touches the + response or the database at all. + - Plugin ordering is set explicitly with `movePluginsTop` and re-asserted every time the profile is + applied, so re-applying `imio.googleauthenticator:default` now restores the ordering if another + add-on displaces it. Previously it was only set on first install. + - The credentials wipe now runs before first-factor delegation, so an exception mid-login refuses + the login instead of leaving intact credentials for a later authentication plugin. + - The `credentials_basic_auth` decision, phrased as whichever way it went, with a pointer to the + README section. + - `README.rst` documents the Zope-root limitation and the Basic Auth / WebDAV / FTP / XML-RPC + consequence with the service-account alternative. + + If Open Question 3 turned out to require `movePluginsTop(IChallengePlugin, ...)`, add a bullet for + that too — it is an operator-visible ordering change in a second plugin list. + + + + bin/test -t '!robot' + + + + - `bin/test -t '!robot'` exits 0. + - `python -c "import docutils.core; docutils.core.publish_doctree(open('CHANGES.rst').read())"` + produces no `SEVERE`/`ERROR` output, or the summary records why the check could not run. + - The new bullets sit inside the `1.0.0 (unreleased)` section and no released section is + modified — `git diff CHANGES.rst` shows additions only above the first released version + heading. + - Every bullet corresponds to something recorded in an `04-0N-SUMMARY.md`; there is no entry for + work that was planned but not shipped (in particular, no changelog line for an optional test + that was skipped or for Task 2 of plan 04-01 if it was dropped). + - `git diff --name-only` for this task lists only `CHANGES.rst`. + + + + The changelog describes the phase as shipped, sourced from the summaries, with nothing claimed + that was not done. + + + + + + +This plan carries 2 of the phase's 11 edge-probe rows, both `unresolved`, neither auto-backstopped. +Phase accounting: 04-01 carries 2, 04-02 carries 3, 04-03 carries 4, 04-04 carries 2 — 11 of 11. + +1. **DOC-01 · `unclassified`** — surfaced, and stated plainly: documentation has no edge case in the + probe's sense. There is no empty, adjacent, single-element or null input to a README paragraph, and + contorting a task to invent one would produce a worse test, not a better plan. The nearest + *genuine* question in this domain is "does the assertion survive a legitimate rewrite?", which is + answered by asserting on identifiers (`Control_Panel`, `acl_users`, `inituser`, `emergency user`) + rather than on sentences, and enforced by the delete-the-section mutation check. Carried as a + `verification: backstop` truth so a verifier that cannot find explicit edge-case evidence abstains + rather than passing silently. + +2. **DOC-02 · `concurrency`** ("If interrupted or run in parallel, what is guaranteed?") — no genuine + domain analogue exists, and this is said explicitly rather than dressed up. A README section is + not executed, not interrupted and not concurrent. The row is recorded here so the accounting + equality holds and so a later reader can see it was considered and rejected on the merits, not + dropped. Carried as a `verification: backstop` truth for the same reason as above. + +Both are examples of the probe's collection/algorithm vocabulary landing poorly on a prose +requirement, which the planning brief anticipated. Neither was translated into a test. + + + +## Trust Boundaries + +| Boundary | Description | +|----------|-------------| +| Plone site `acl_users` → Zope root user folder | The plugin's authority stops here.

Assertions are on identifiers, never prose, so rewording stays free. Prohibition P1. | +| T-04-32 | Denial of Service | a script or integration broken by the basic-auth decision with no documented alternative, leading an operator to "fix" it by disabling two-step verification for a human account — turning an availability problem into an authentication one | medium | mitigate | Task 1(b) paragraph 3 names a real, already-shipped alternative: a service account with `enable_two_factor_authentication` false plus a CIDR entry in the existing `ip_addresses_whitelist`, checked by `authenticateCredentials` before anything else.

The `` on Task 1 halts if `04-02-SUMMARY.md` is missing. | +| T-04-SC | Tampering | npm/pip/cargo installs | low | accept | This plan installs nothing and touches no dependency declaration. `docutils` is used only as an optional local validity check with a documented fallback if it is unavailable.

The pre-existing `test_readme_documents_the_deployment_key_and_its_failure_mode` (DOC-03) is untouched. +- `CHANGES.rst` — six new bullets in `1.0.0 (unreleased)` covering phase 4 as shipped; no released version section touched. + +## Decisions Made + +- **DOC-02's test asserts the branch actually taken.** `credentials_basic_auth` was kept active (04-02's checkpoint), so the README names the plugin's index-0 ordering as what protects that path, and the test asserts the literal phrase "index 0" that the README uses for it — a branch-specific check, not a generic one, so a future reversal of the decision without a README update goes red rather than staying silently stale. +- **Placement of the new sections**: directly after "Notes", before "Implementation details" — operational scope an operator should hit before internals, per the plan's explicit instruction. +- **"ZMI -> acl_users" kept, not replaced**: the ordered list and "critical!" emphasis stay (an operator who finds the order wrong in the ZMI still needs the reference list and the reason it matters); only the framing changed from "make sure" (manual install step) to "verify... and if wrong, re-apply the profile" (verification + recovery). +- **`docs/index.rst` left untouched**, per phase 3's established precedent that it is a stale pre-rename duplicate never kept in sync with `README.rst`. Verified via `git diff --name-only` on both task commits. + +## Mutation Checks + +Both required by the plan's acceptance criteria, run once during execution and recorded here (not merely claimed): + +**DOC-01**: temporarily deleted the "What two-step verification does not cover" section from `README.rst` (a Python one-liner slicing the file between that heading and the next), ran `bin/test -t test_readme_documents_zope_root_limitation` — **failed** with `AssertionError: 'inituser' not found in ...` (the first-checked fact after the section was removed). Confirmed red, then restored the file. + +**DOC-02**: temporarily deleted the "HTTP Basic Auth, WebDAV, FTP and XML-RPC" section, ran `bin/test -t test_readme_documents_basic_auth_consequence` — **failed** with `AssertionError: 'credentials_basic_auth' not found in ...`. Confirmed red, then restored the file. + +After both checks, `README.rst` was restored from a saved pre-edit copy and confirmed **byte-identical** via `diff -q` before Task 1's commit was made — the mutation checks left no trace in the committed diff. + +## reStructuredText Validity + +`docutils` is not importable under `bin/python` or the system `python3` (`ModuleNotFoundError: No module named 'docutils'` in both). Built a throwaway virtualenv in the scratchpad directory (`python3 -m venv` + `pip install docutils`) solely to run the check the plan's acceptance criteria specify — this installs nothing into the project's own buildout/eggs and is not part of the shipped dependency set. `docutils.core.publish_doctree(...)` with `report_level=1, halt_level=5` (forcing every diagnostic to surface) produced **no output at all** for both `README.rst` and `CHANGES.rst` after this plan's edits — clean, no `SEVERE`/`ERROR`/`WARNING` nodes. + +## Deviations from Plan + +None - plan executed exactly as written.

All eight research-priority questions came back with a +concrete file:line answer; none required a web search. There are no new third-party packages in +this phase, so there is no Package Legitimacy Audit to run — the phase is pure standard-library/eggs +plumbing on top of the four modules already at the center of the codebase +(`pas_plugin.py`, `setuphandlers.py`, `helpers.py`, `browser/forms/token.py`). + +The chain that makes the veto work is: `PluggableAuthService._extractUserIds` calls every +`IAuthenticationPlugin.authenticateCredentials(credentials)` **in plugin order**, in a loop that +passes the **same dict object** to each call and never breaks on success — so wiping `credentials` +in place inside our plugin genuinely blinds every authenticator listed *after* ours in that same +call, and does nothing for ones listed before it. That is why plugin order is not a nicety here, it +*is* the security control (`PluggableAuthService.py:648-667`), and why `movePluginsTop` (which +exists, with exactly the signature the roadmap assumes, in `Products.PluginRegistry==1.4.1`) has to +replace the current `movePluginsDown(iface, listPlugins(iface)[:-1])` idiom in `setuphandlers.py`. + +The redirect-body-leak bug (MFA-02) has a precise root cause: `HTTPResponse.redirect(url, lock=1)` +is two lines — `setStatus(302, lock=1)` and `setHeader('Location', url)` — and locking the status +only blocks a *later* `setStatus()` call from changing the numeric code; it does nothing to the +response body (`ZPublisher/HTTPResponse.py:606-611`, `:204-239`). Because `authenticateCredentials` +runs during traversal/authorization, *before* `mapply()` renders the requested view and calls +`response.setBody(result)` (`ZPublisher/Publish.py:127-141`), any redirect issued from +`authenticateCredentials` gets its Location header and locked 302 status, and then the originally +requested page's HTML is rendered into the body anyway right afterward — exactly the leak the +roadmap describes, and exactly what the current `pas_plugin.py:169` line does today. Fixing it means +never rendering the original view at all (challenge path) or overwriting the body after it renders +(`IPubBeforeCommit` path) — `response.redirect()` alone, on its own, fixes neither. + +`IPubBeforeCommit` fires *after* `mapply()`/`setBody()` and *before* `transactions_manager.commit()` +and before the body is ever flushed to the client (`Publish.py:134-146`, confirmed again by +`publish_module_standard`'s `outputBody()` call happening only after `publish()` returns, +`Publish.py:264-267`) — so a subscriber there genuinely can still overwrite status, headers and +body; `plone.transformchain`, already in this buildout's egg cache, does precisely this in +production (`plone/transformchain/zpublisher.py:81-96`) and is the concrete pattern to copy. +`IChallengePlugin.challenge()`, by contrast, is reached only after an `Unauthorized` exception has +propagated all the way out of `publish()`, and `publish()`'s own exception handling runs +`transactions_manager.abort()` in a `finally:` block *before* re-raising +(`Publish.py:187-198`/`:213-222`) — so by the time `response.exception()` calls PAS's +`_unauthorized()` → `challenge()` (`HTTPResponse.py:789-800`, `PluggableAuthService.py:1140-1192`), +the transaction for that request is already gone. Any write inside `challenge()` is discarded, full +stop; this is not a timing race, it is a hard ordering guarantee in the publisher. + +The `credentials_basic_auth` deactivation decision: three sibling iMio repos were searched +(`imio.dms.mail`, `server.dmsmail`, `industrialisation`) and turned up no live dependency on HTTP +Basic Auth *against this Plone site's own `acl_users`*. `server.dmsmail`'s only `webdav-address` +setting is commented out in every buildout config found, no XML-RPC client targeting the site was +found, and the one script that does use HTTP Basic Auth with `requests` +(`scripts/run-copy-missing-blobs.py`) authenticates *outward* to a different, remote "source" site, +not into this one. The one script that does Basic-Auth into *this* Zope process +(`pack_zeo.sh`, from `industrialisation`) targets `/Control_Panel/Database/.../manage_pack` — the +Zope-root `Control_Panel`, which sits above any Plone site's `acl_users` and is exactly the +DOC-01 "architecturally out of reach" boundary, so it is unaffected by this site's PAS +configuration either way. This is real but not literally exhaustive evidence (three repos, not +every iMio repo); see Assumptions Log A1. + +**Primary recommendation:** Fix the ordering with `movePluginsTop` (structural, required regardless +of the basic-auth decision), keep `authenticateCredentials` write-free of `RESPONSE`, split the +actual redirect into an `IChallengePlugin.challenge()` (Unauthorized path, no writes, no `protocol` +attribute set) and an `IPubBeforeCommit` subscriber (login-POST path, explicit `setBody('')` after +`redirect()`/before returning), and **additionally** deactivate `credentials_basic_auth` site-wide as +defense in depth, since the ordering fix alone is correct but silently reversible by any future +plugin reorder, while deactivation removes the vulnerable code path structurally. + +## Architectural Responsibility Map + +| Capability | Primary Tier | Secondary Tier | Rationale | +|------------|-------------|----------------|-----------| +| Password verification delegation | API/Backend (PAS plugin) | — | `authenticateCredentials` already delegates to other `IAuthenticationPlugin`s; this phase does not change that delegation, only what happens after it | +| Credentials-dict veto | API/Backend (PAS plugin) | — | In-process mutation of a shared dict inside the single Zope publish cycle; no ZODB, no cookie, no cross-request state | +| 2FA-pending signal | API/Backend (`request` attribute) | — | `request['_2fa_pending']` is per-request, set in `authenticateCredentials`, read by the challenge plugin and the pub-event subscriber later in the *same* request — never persisted | +| Unauthorized-path redirect | API/Backend (`IChallengePlugin`) | — | Reached only from `HTTPResponse.exception()`, after `transaction.abort()`; must be write-free by construction, not by discipline | +| Login-POST-200 redirect | API/Backend (`IPubBeforeCommit` subscriber) | — | Reached from the success path of `ZPublisher.Publish.publish`, before commit; the only hook that can intervene on a request that never raises | +| Plugin ordering | API/Backend (GenericSetup install handler) | — | `Products.PluginRegistry.movePluginsTop`, invoked once at install time from `setuphandlers.py`; not a per-request concern | +| Basic-auth extractor policy | API/Backend (PAS plugin registry) | — | Site-wide toggle on `acl_users.plugins`, decided once, not per-request | +| Documentation of the Zope-root/basic-auth boundary | Docs (README.rst) | — | No code tier; DOC-01/DOC-02 are prose requirements | + +## Standard Stack + +No new third-party dependency is introduced by this phase.

A `None` from our plugin changes nothing about what +`source_users` (or any other authenticator) independently returns for the *same, unmodified* +credentials dict. +**How to avoid:** The only observable effect our plugin can have on later authenticators in the +*same* `for authenticator_id, auth in authenticators:` loop iteration is mutating the shared +`credentials` dict object in place — which is exactly what the code already does +(`pas_plugin.py:148-149`) and exactly why ordering (this plugin listed *before* `source_users`) +is required for the mutation to reach it. +**Warning signs:** A veto test that passes only because the test's plugin list happens to already +be ordered correctly, with no explicit ordering assertion — this is precisely what MFA-03 exists to +catch. + +### Pitfall 2: Believing a lock on status locks the body +**What goes wrong:** `response.redirect(url, lock=1)` reads as "make this redirect final," and a +reviewer assumes the response is now closed to further changes. +**Why it happens:** `lock` really does prevent a *later* `setStatus()` call from overwriting the +302 (`HTTPResponse.py:211-214`) — that part of the mental model is correct. What's missing is that +`setBody()` has no such lock at all, and nothing in the redirect call path ever calls it. +**How to avoid:** Either don't let `mapply()` run against the original view at all (challenge-path +early exit) or explicitly `setBody('')` after the redirect (pub-event path). +**Warning signs:** A manual `curl` (no `-L`) against a 2FA-gated URL returning a 302 with a +non-empty body containing recognizable page content. + +### Pitfall 3: Writing state inside the challenge plugin because "it feels like the right place" +**What goes wrong:** A lockout counter, a "challenge issued" flag, or any `setMemberProperties` call +placed inside `challenge()` because that's where the redirect logic naturally lives. +**Why it happens:** `challenge()` has a `response` argument and looks like a normal view-ish +callable. +**How to avoid:** Remember the calling context: `challenge()` runs only after +`transactions_manager.abort()` has already executed for this request (`Publish.py:194`/`:218`, +confirmed by the fact that `err_hook`'s `finally:` block runs the abort *before* re-raising, which +is what eventually reaches `response.exception()` → `challenge()`). Any write here is thrown away +100% of the time, silently — no exception, no log line, just a lockout that never locks. This is +explicitly why MFA-12 (Phase 5) requires all second-factor state writes to live in the token form +view, and this phase's `challenge()`/subscriber must stay write-free from day one so Phase 5 doesn't +have to retrofit it. + +### Pitfall 4: Assuming a `plone.testing.z2.Browser` test proves the veto held +**What goes wrong:** A `Browser` POST to `login_form` with a 2FA user's credentials "looks" like the +strongest possible test, so the PAS-level plugin-order assertion (MFA-03) gets skipped as redundant. +**Why it happens:** An end-to-end browser test does exercise the real HTTP path, which is valuable, +but `zope.testbrowser`-family browsers may auto-follow redirects by default, silently hiding whether +the pre-redirect body was non-empty (MFA-02) unless redirect-following is explicitly disabled for +that one assertion. +**How to avoid:** Use the existing unit-level idiom (`self.pas._extractUserIds(request, +self.pas.plugins)` with `setRequest(request)` bound, as in +`tests/test_pas_plugin.py:138-193`) for the "no session granted" assertions per extractor (MFA-04), +which exercises PAS's real loop without going through full HTTP publish, and reserve the +`Browser`-based test specifically for the body-emptiness and redirect-target assertions where a real +`HTTPResponse` is unavoidable. +**Warning signs:** A `Browser`-based veto test that passes today for the wrong reason (e.g. the +2FA-enabled user's password was simply wrong in the test fixture, or the browser followed the +redirect to a page that also happens to render "please log in"). + +## Code Examples + +### Confirmed authenticator-accumulation loop (Q1) +```python +# Source: Products.PluggableAuthService.PluggableAuthService, installed egg +# Products.PluggableAuthService-1.11.3-py2.7-linux-x86_64.egg, +# PluggableAuthService.py:648-667 (inside _extractUserIds) +user_ids = [] +for authenticator_id, auth in authenticators: + try: + uid_and_info = auth.authenticateCredentials(credentials) + if uid_and_info is None: + continue + user_id, info = uid_and_info + except _SWALLOWABLE_PLUGIN_EXCEPTIONS: + reraise(auth) + msg = 'AuthenticationPlugin %s error' % (authenticator_id, ) + logger.debug(msg, exc_info=True) + continue + if user_id is not None: + user_ids.append((user_id, info)) +``` +Confirms: (a) `credentials` is the same dict object passed to every authenticator in this loop — +in-place mutation by an earlier plugin is observed by a later one; (b) there is no `break` on +success — every authenticator gets called and every non-`None` result is appended; (c) `return None` +from one plugin has zero effect on any other plugin's independent result. + +### Confirmed `ZCacheable_get` gating (Q2) +```python +# Source: Zope2 2.13.30, OFS/Cache.py:150-168 +def ZCacheable_get(self, view_name='', keywords=None, mtime_func=None, default=None): + c = self.ZCacheable_getCache() + if c is not None and self.__enabled: + ... + return default +``` +`ZCacheable_getCache()` returns `None` unless a `ZCacheManager` object has been added *and* +associated via `ZCacheable_setManagerId` (`OFS/Cache.py:104-135`).

If some other deployed script or integration does rely on Basic Auth into a `server.dmsmail`-family site, deactivating `credentials_basic_auth` site-wide would break it silently until someone reports failed automation. **This is exactly why the phase notes require the decision to be settled with evidence, not assumed** — treat this finding as strong-but-not-exhaustive and gate the actual deactivation behind a `checkpoint:human-verify` naming the repos searched. | +| A2 | The phase's "returns HTTP 200" framing for the login-POST path describes `login_form`'s baseline (pre-fix) behavior on invalid credentials, not a hard requirement that our own redirect must itself be status 200 rather than 302 | Architecture Patterns, Open Questions | If a plan or test enforces literal 200 on the *final* response instead of 302-to-token-form, the implementation could end up serving the token form's HTML directly at 200 instead of redirecting — a materially different (and untested-here) UX/security shape.

For a user with `enable_two_factor_authentication=True` but no +secret yet (e.g. an admin flips the flag on an existing account without walking it +through the enrollment wizard), `authenticateCredentials` does **not** raise even when +`IMIO_GOOGLEAUTHENTICATOR_SEED_KEY` is unset or malformed -- it stashes the pending flag +and returns `None` as if everything were fine. + +The failure is deferred to `subscribers.redirect_pending_2fa` (`IPubBeforeCommit`) or +`pas_plugin.challenge` (`Unauthorized`), whose call to `send_2fa_redirect` -> +`sign_user_data` -> `get_or_create_secret` -> `generate_secret` -> `encrypt_seed` -> +`_get_fernet` raises there instead. I proved this empirically: with the env var unset +and a 2FA-enabled user whose secret property is `''`, `self.pas._extractUserIds(...)` +completes without raising, and `pas_plugin.send_2fa_redirect(request, request.response)` +is what actually raises `ValueError`.

Disabling it needs both `mech_browser.set_handle_redirect(False)` and `raiseHttpErrors = False`, and those switches are only honoured on the `Browser.open()` path — `Browser.getControl(...).click()` routes through `_clickSubmit()`, which re-raises `mechanize.HTTPError` unconditionally and never consults `raiseHttpErrors`. `test_no_body_leak_over_http` (`tests/test_challenge.py:229`) therefore submits URL-encoded POST data through `Browser.open()` directly.

Both pass.

Both share `send_2fa_redirect`. `test_challenge_fires_on_unauthorized` (real HTTP, Basic Auth, non-vacuity control proving the URL is genuinely protected) and `test_pub_before_commit_fires_on_login_post` (real HTTP, login-form POST, ZCML wiring parsed with `xml.dom.minidom`) both pass independently. | +| 5 | An exception inside `authenticateCredentials` wipes credentials and refuses rather than falling through to `source_users`; DOC-01 and DOC-02 written | VERIFIED | `test_exception_path_still_wipes_credentials` passes.

It is not `one-way`: the orphaned values are resettable counters, so no data migration is owed and no published contract breaks. Flagged, not gated. | +| P5-02 | No upgrade step and no profile version bump. | `reversible` | Nothing has shipped at profile `1000` (`setup.py` is `1.0.0.dev0`), and Phase 1 renamed the profile id, so every site installs this profile fresh rather than upgrading. There is no in-repo analog to copy (`upgrades/` does not exist; `CLAUDE.md`'s `to0301.py` reference is stale). Consequence, recorded honestly: an already-installed site must reimport the profile, and the failure mode if it does not is **loud** -- `registry.forInterface` raises on the two missing records, and `getProperty` raises `ValueError` on an undeclared property -- never a silent unlockable lockout. Plan 05-03 writes this into `CHANGES.rst`. | +| P5-03 | `registry.xml` is not edited. | `reversible` | **Verified against the file, not assumed:** `profiles/default/registry.xml` contains exactly one `` node with no child `` elements, so `plone.app.registry`'s importer seeds every field the Python interface declares using the schema default. The absence of a `registry.xml` diff is correct and must not be flagged as an omission. | +| P5-04 | Counter and lock live behind three functions in `helpers.py`, called from the two form views. | `reversible` | `CLAUDE.md`: "`helpers.py` holds essentially all the logic ... put new behaviour there and unit-test it in `tests/test_helpers.py`." Two views need the same gate; one shared implementation is a smaller diff than two copies, and it is the root-cause placement. MFA-12 is preserved by *who calls* them, pinned by `test_no_second_factor_state_written_from_the_plugin`. | +| P5-05 | Setting the lock also zeroes the attempt counter, in the same write. | `reversible` | After the lock expires the user gets a fresh N attempts rather than being re-locked by a single mistype. This is also the arithmetic behind the roadmap's own "N=5 / 900 s = ~1042 days" figure: 5 attempts per 900 s window. | +| P5-06 | `tests/test_token.py`, not `tests/test_token_form.py`. | `reversible` | **Deviation from 05-VALIDATION.md, stated explicitly.** The `imio-plone:plone-write-tests` skill R5 requires the test module name to match the production module (`browser/forms/token.py`), and the package already follows that for both sibling forms (`test_user_setup.py`, `test_request_bar_code_reset.py`). Task 3 updates the two 05-VALIDATION.md rows that name the old file. | +| P5-07 | One test method per *requirement*, not per production method. | `reversible` | **Deviation from skill R5, flagged as R7 requires.** The precedent is already recorded in-package: `tests/test_challenge.py` and `tests/test_setuphandlers.py` both carry a `WR-03` class docstring stating this exact deviation and its reason (a failure in one requirement's assertions must not hide whether the others pass). New classes cite that precedent in their docstrings rather than re-litigating it. | + +## Multi-Source Coverage Audit + +| SOURCE | ID | Feature / Requirement | Plan | Status | Notes | +|---|---|---|---|---|---| +| GOAL | — | Previous-step code works, a used code never works again, brute force stops after N, counters survive their request | 05-01, 05-02, 05-03 | COVERED | | +| REQ | MFA-05 | Previous time step accepted | 05-02 | COVERED | | +| REQ | MFA-06 | Consumed code rejected on reuse, logged without plaintext username | 05-02 | COVERED | | +| REQ | MFA-07 | Only exactly-6-digit input is a candidate token | 05-02 | COVERED | | +| REQ | MFA-08 | N failures lock for the configured duration, lock checked before the token | 05-01, 05-03 | COVERED | | +| REQ | MFA-09 | Lock expires on its own | 05-01 | COVERED | | +| REQ | MFA-10 | N and duration editable, defaults 5 / 900 | 05-01 | COVERED | | +| REQ | MFA-11 | Success resets the counter | 05-01, 05-03 | COVERED | | +| REQ | MFA-12 | No second-factor state written from the PAS plugin or a challenge plugin | 05-01 | COVERED | | +| REQ | MFA-13 | Every new property declared + round-trip tested | 05-01 | COVERED | | +| RESEARCH | — | Drift built on `get_hotp(secret, intervals_no=i)` for `current` and `current-1` only | 05-02 | COVERED | | +| RESEARCH | — | Replay state as a single last-accepted-interval int, not a consumed-code list | 05-02 | COVERED | | +| RESEARCH | — | New exact-6-digit gate in this package, before any `onetimepass` call | 05-02 | COVERED | `_is_possible_token` is inside the pinned egg and is not patchable | +| RESEARCH | — | `test_seed_encryption_round_trip` moves to `get_totp(seed, as_string=True)` in the same commit as the gate | 05-02 | COVERED | Pitfall 2 | +| RESEARCH | — | Three `type="int"` properties; `int()`-coerce before every write | 05-01 | COVERED | Pitfall 3 | +| RESEARCH | — | No broad `except Exception` around the lockout write | 05-01, 05-03 | COVERED | Pitfall 3 | +| RESEARCH | — | Two `zope.schema.Int` fields on the existing interface, existing form, no `registry.xml` edit | 05-01 | COVERED | Pattern 3, decision P5-03 | +| RESEARCH | — | Lock evaluated before `validate_token`; identical generic message | 05-01, 05-03 | COVERED | | +| CONTEXT | — | No CONTEXT.md exists for this phase | — | N/A | ROADMAP Phase notes treated as locked, reproduced in 05-RESEARCH `` | +| ROADMAP note | — | Lockout covers `token.py` **and** `reset_bar_code.py`; `user_setup.py` excluded | 05-01, 05-03 | COVERED | Operator decision 2026-07-31 | +| ROADMAP note | — | Smoke-test the GenericSetup import for the new field types | 05-01 | COVERED | Task 2 | +| ROADMAP note | — | Prefer an `int` epoch over `float`/`date` | 05-01 | COVERED | | +| STATE blocker | — | R-04-C: do not attach lockout or replay state to the `send_2fa_redirect` call chain | 05-01 | COVERED | T-05-07, pinned by `test_no_second_factor_state_written_from_the_plugin` | +| STATE blocker | — | WR-01 / WR-02: `check_encryption_key_is_usable()` for the never-enrolled state | NONE | OUT OF SCOPE | Not one of MFA-05..13 and not a Phase 5 success criterion.

A `PropertyValueError` from a +mis-declared property must reach the developer as a 500, not be downgraded into a lockout +that silently never locks. + +**5. `browser/forms/token.py`.** Add three imports next to the existing four `from +imio.googleauthenticator.helpers import ...` lines: `is_account_locked`, +`register_failed_second_factor`, `reset_failed_second_factor`. Inside `handleSubmit`, in the +existing `if username:` block, immediately after `user = api.user.get(username=username)` +and **before** the `validate_user_data` call: if `user is not None` and +`is_account_locked(user)`, add the existing `_("Invalid token or token expired.")` message +(the identical string already used on the wrong-code branch, reused verbatim so a locked +account is indistinguishable from a wrong code) with severity `error`, then `return`.

Writes are confined to the form views; `test_no_second_factor_state_written_from_the_plugin` pins it at source level and `test_failed_attempt_counter_survives_unauthorized_request` proves the surviving path. Also closes the standing R-04-C constraint. | +| T-05-06 | Tampering (of the control itself) | `helpers.register_failed_second_factor` | medium | mitigate | The `int` property inspector is an `isinstance` check that raises `PropertyValueError` for a `float` rather than coercing.

This reproduces the real vulnerability class the test protects against (the lock stops gating login once the check is no longer strictly prior to the success/failure dispatch) and turned the test red as required (`AssertionError: '@@google-authenticator-token' not found in 'http://nohost/plone'`). Restored byte-identical afterwards. +- **Files affected:** `src/imio/googleauthenticator/browser/forms/token.py` (mutated and restored, not part of the final commit). +- **Verification:** `bin/test -t test_locked_account_response_is_the_same_for_a_valid_and_an_invalid_code` went red under the mutation, green after restore; full suite re-run green (76 tests). + +--- + +**Total deviations:** 0 auto-fixed. 1 clarification recorded above (methodology note on how a non-vacuity check was satisfied, not a change in scope or behaviour). +**Impact on plan:** None on delivered scope. The clarification only concerns how the required non-vacuity proof was constructed. + +## Issues Encountered +- `Location` header from `PluggableAuthService.challenge()`'s `response.redirect(signed_url, lock=1)` is relative to the portal root, not absolute -- `test_failed_attempt_counter_survives_unauthorized_request`'s second request had to resolve it against `self.portal_url` before a fresh `Browser` (which has no current document) could `.open()` it. Test-only fix, no production code touched. +- `plone.supermodel`'s `fieldset(...)` tagged-value key is `plone.supermodel.fieldsets` (via `FIELDSETS_KEY`), not `plone.autoform.fieldsets` as initially assumed while writing `test_control_panel_has_lockout_fields`; confirmed by reading `/srv/cache/eggs/plone.supermodel-1.2.7-py2.7-linux-x86_64.egg/plone/supermodel/directives.py` (the egg this buildout's own `bin/test` actually resolves, distinct from a same-named egg elsewhere on the machine) before writing the assertion. + +## User Setup Required + +None - no external service configuration required. + +## Next Phase Readiness +- Plan 05-02 (drift/replay) can build directly on `two_factor_authentication_last_interval`, which is declared and round-trip-proven here but has no reader/writer yet. +- Plan 05-03 (reset-bar-code lockout) reuses `is_account_locked`/`register_failed_second_factor`/`reset_failed_second_factor` from `helpers.py` unchanged; `browser/forms/reset_bar_code.py` is untouched by this plan. +- `bin/test -t '!robot'` is green at 76 tests (up from the 66 recorded at phase seed time), with Phase 4's `test_challenge`/`test_pas_plugin` baseline (19 tests) still passing unmodified. +- No blockers. + +--- +*Phase: 05-drift-replay-and-lockout* +*Completed: 2026-07-31* + +## Self-Check: PASSED + +All 12 created/modified files confirmed present on disk;

Behaviour is identical; drift and replay still land in one commit. | +| P5-09 | The last-accepted-interval write lives inside `helpers.validate_token`, not in the calling view. | `reversible` | **Resolves the internal ambiguity in 05-RESEARCH.md** (Pattern 1 says the caller writes; the Summary and Pitfall 5 say the write is safe in all three views). A caller-side write would leave `reset_bar_code.py` and `user_setup.py` replay-vulnerable, and the operator's scope decision explicitly put `reset_bar_code.py` in scope. MFA-12 is unaffected: `validate_token` is called from three form views and from nothing else -- confirmed by grep over `src/imio/`. | +| P5-10 | The format gate accepts only ASCII digits `0`-`9`, not everything `unicode.isdigit()` accepts. | `reversible` | In Python 2 a superscript or Arabic-Indic digit satisfies `isdigit()`, and `int()` raises `ValueError` on the superscript form. Since `@@google-authenticator-token` and `@@reset-bar-code` are both registered `permission="zope2.View"`, that would be an anonymously reachable 500 rather than a refusal. Refusing non-ASCII digits is the same number of lines. | +| P5-11 | The replay-rejection log line carries no operand at all. | `reversible` | The convention is already set by `helpers.validate_bar_code_reset_token`'s docstring: "Do not log either operand at any level."

One name per line, per `.isort.cfg`'s +`force_single_line`. Add a module constant `TOTP_INTERVAL_SECONDS = 30` next to the existing +`ENV_VAR_NAME` / `CIPHERTEXT_VERSION_PREFIX` constants, with a one-line comment naming RFC 6238 +section 5.2's default time step. + +**2. `_is_six_digit_token(token)`.** Coerce a non-string argument with `str(...)`, then return +true only when the value has length exactly 6 and every character is an ASCII digit. Test +membership against the literal ten-character digit string rather than calling `isdigit()` +alone: in Python 2 `unicode.isdigit()` is true for a superscript two, and `int()` then raises +`ValueError`, which on a `permission="zope2.View"` form is a 500 instead of a refusal +(decision P5-10). Docstring in this module's `:param Type name:` / `:return bool:` style, +noting that the pinned `onetimepass==0.2.2` accepts numeric strings of length 1 to 6 through a +private function that is not exported and cannot be overridden, which is why this gate exists +here. + +**3. `_find_accepted_interval(token, secret)`.** Pure function, no ZODB access, no logging. +Compute `current_interval` as `int(time.time()) // TOTP_INTERVAL_SECONDS`. For `interval` in +the two-element tuple `(current_interval, current_interval - 1)` -- in that order and never +`current_interval + 1` -- return `interval` as soon as +`get_hotp(secret, intervals_no=interval)` equals `int(token)`. Return `None` when neither +matches. Docstring must state that RFC 6238 drift tolerance is backward-looking only and that +`onetimepass.valid_hotp` cannot be reused because its `last`/`trials` parameters search +forward from `last + 1`. + +**4. `validate_token(token, user=None)`.** Same signature, same three call sites. New body, in +this order: + a. Resolve `user` from `api.user.get_current()` when it is `None` (unchanged). + b. Return `False` unless `_is_six_digit_token(token)`. This is before the seed is fetched, so + garbage input never triggers a decrypt. + c. `secret = get_secret(user)`; if falsy, return `False`. **Keep the existing multi-paragraph + comment verbatim** -- it records why the guard lives here rather than in the three callers, + and why a decryption `ValueError` must keep propagating rather than being downgraded to a + wrong-token answer. + d. Read `two_factor_authentication_last_interval` off the user and coerce with + `int(... or 0)`. The `or 0` is load-bearing for the same reason as in plan 05-01's lock + read: a Zope-root account's memberdata wrapper returns `''`. + e. `matched = _find_accepted_interval(token, secret)`. If `matched` is `None`, return `False`. + f. If `matched` is less than or equal to the stored interval, emit a single `logger.info` + call whose message names only the event -- no username, no user id, no token, no secret, + no interval number (decision P5-11, following `validate_bar_code_reset_token`'s stated + convention) -- and return `False`. + g. Otherwise write `two_factor_authentication_last_interval` with one + `user.setMemberProperties(mapping={...})` call carrying `int(matched)`, and return `True`. +Update the docstring to describe the accepted window, the replay rule and the write. + +**5. `tests/test_helpers.py` -- the mandatory same-commit regression fix.** At the SEC-01 +end-to-end assertion inside `test_seed_encryption_round_trip`, change the token argument from +`get_totp(seed)` to `get_totp(seed, as_string=True)`. `get_totp` with the library default +returns a bare, non-zero-padded `int`, so roughly one attempt in ten produces fewer than six +characters and would fail the new gate intermittently. Add a short comment naming this as the +reason, so a later reader does not "simplify" it back. + +**6. `tests/test_helpers.py` -- four new methods** on the `TestDriftAndReplay` class created by +plan 05-01 (its `setUp`/`tearDown` already handle the seed-key env var and the mandatory +re-login). Compute expected codes with `onetimepass.get_hotp(seed, intervals_no=..., as_string=True)` +against the plaintext seed returned by `generate_secret`, and reset +`two_factor_authentication_last_interval` to 0 at the start of each method so no method depends +on another's write: + - `test_validate_token_accepts_previous_interval` -- the code for `current - 1` is accepted, + and the stored interval then reads back `current - 1`. + - `test_validate_token_rejects_future_interval` -- the code for `current + 1` is refused, and + the stored interval is unchanged.

The same lock and counter as the token form now gate it, evaluated before `validate_token`. `test_reset_bar_code_lockout_after_five_failures`, whose step 5 asserts the login form has no separate attempt budget. | +| T-05-08 | Denial of Service | `browser/forms/reset_bar_code.py::handleSubmit` | medium | accept | An anonymous party can lock a named account by submitting `max_failed_attempts` wrong codes with that account in `auth_user`. Accepted (decision P5-13): bounded to `lockout_duration` seconds by MFA-09's self-expiry, asserted in step 6 of the test. Both alternatives are worse -- leaving the path unmetered restores T-05-16, and admin-unlock-only lockout is ruled out in REQUIREMENTS.md as a DoS primitive. | +| T-05-06 | Tampering (of the control itself) | the counter write inside `handleSubmit` | high | mitigate | This file already contains a broad `except Exception: logger.exception(...)` that would convert a `PropertyValueError` from a mis-declared property into "An unexpected error occurred." -- a lockout that silently never locks. Both new calls are placed outside that block, asserted by line-order acceptance criteria. | +| T-05-03 | Information Disclosure | the locked-account response here | medium | mitigate | The locked branch reuses the existing wrong-code message string verbatim, so no new i18n msgid and no distinguishable response. Asserted by the message-count criterion in Task 1. | +| T-05-10 | Denial of Service | `browser/forms/user_setup.py` | medium | mitigate | Deliberately excluded, asserted by an empty diff on that file.

Locked and nonexistent therefore converge on the one failure branch that already exists. | + + + + + Task 1: Reorder the lock gate behind the signature check + Swapping two adjacent guard clauses in one handler. Nothing downstream reads the position; a `git revert` of this commit restores the previous behaviour exactly, and the Task 2 test is the thing that would go red if it were ever swapped back. + `helpers.is_account_locked` exists and is already imported in `browser/forms/token.py` (delivered by plan 05-01), and `bin/test -t '!robot'` is green at 82 tests at HEAD. + src/imio/googleauthenticator/browser/forms/token.py + + - src/imio/googleauthenticator/browser/forms/token.py (the whole of `TokenForm.handleSubmit`, not just lines 85-110 -- the `register_failed_second_factor` / `reset_failed_second_factor` calls further down must be located before anything is moved, so it can be shown they did not move) + - src/imio/googleauthenticator/browser/forms/reset_bar_code.py (`handleSubmit` only -- the sibling handler whose ordering this task copies: account guards, then lock gate, then `validate_token`) + - .planning/phases/05-drift-replay-and-lockout/05-REVIEW.md (the CR-01 section, which already carries the concrete before/after) + + +In `TokenForm.handleSubmit`, the block that begins `if user is not None and is_account_locked(user):` +currently sits between the `if username:` / `api.user.get` lookup and the +`user_data_validation_result = validate_user_data(request=self.request, user=user)` call.

Replace it with a comment that says +why the position is load-bearing in both directions: the gate runs only once +`validate_user_data` has succeeded, so an unsigned caller learns nothing about the account, and +it still runs ahead of `validate_token`, so a locked account never reaches TOTP arithmetic. +Name `validate_user_data` and `validate_token` in that comment, so a future reader moving either +call sees the constraint. Cite the requirement as MFA-08. + +Change nothing else. Do not move, wrap, duplicate or add a `try`/`except` around the +`register_failed_second_factor` or `reset_failed_second_factor` calls further down the handler: +they stay on this same non-aborting view path, which is what MFA-12 buys.

Fixing it later is a strictly additive change to the same two branches. | +| P5-18 | The locked branch adopts `Setup failed! {0}`, rather than the tail adopting `Resetting of the bar-code failed! {0}`, and rather than restructuring the handler so both exit through one emission point. | `reversible` (two-way -- a string change, no migration, no published contract, `git revert` restores the previous behaviour exactly, and the Task 1 test is what goes red if it is ever swapped back). No `checkpoint:decision` is warranted. | `Setup failed! {0}` is what the wrong-code path already emits at the tail and what `user_setup.py` emits for the same reason; moving the *lock* to meet the *wrong code* is the direction that makes the lock look like the common case rather than the reverse. Restructuring to a single emission point would touch the `try`/`except` region that plan 05-03's T-05-06 deliberately fenced off, for no gain the test can observe. | +| P5-19 | The test asserts equality of the ordered LIST of rendered status messages, not of one extracted message. | `reversible` | `updateFields` also runs on the POST and adds its own signature-failure message for an existing user, so the page carries more than one. Comparing the whole list is both simpler than picking one and strictly stronger: it would also catch a future second message that leaked lock state. | +| P5-20 | Three measurements, three assertions, ordered so a failure is self-diagnosing: same-account locked-vs-unlocked first, then an unlocked-vs-unlocked control across two different accounts, then locked-vs-other-account (the literal `missing[1]` contract). | `reversible` | The same-account toggle holds the username constant, so it isolates lock state with no confound. The two-account control means that if the third assertion ever fails, the second tells the reader immediately whether the cause is the lock or something account-specific and unrelated. | + + + + + Task 1: Make the locked and wrong-code failures at @@reset-bar-code say the same thing, and prove it + One message template swapped for another that already exists in the same file and in every catalogue, plus a comment rewrite and one added test. `git revert` of this commit restores the previous behaviour byte-for-byte.

Mirror + `test_token.py`'s creation call shape (`email`, `username`, `password='Secret0123!'`), then set + `enable_two_factor_authentication` True, call `get_or_create_secret(..., overwrite=True)`, and + `transaction.commit()`.

Then unlock it + (`two_factor_authentication_locked_until` back to 0, `transaction.commit()`), assert + `helpers.is_account_locked` is now False, and capture `unlocked_messages` for the same account + in a fresh browser. Then capture `other_unlocked_messages` for the second account, asserting it + is not locked first. +6. Assert, in this order, with `assertEqual` on the lists and a message on each naming MFA-08: + `locked_messages == unlocked_messages`; then `unlocked_messages == other_unlocked_messages` + (labelled in its assertion message as the control that isolates lock state from anything + account-specific); then `locked_messages == other_unlocked_messages`. Equality of lists, not + `assertIn`, not a substring check, not a comparison of embedded reasons -- an acceptance + criterion of exactly that weaker shape is the documented proximate cause of this defect + shipping. + +Run `bin/test -t test_no_signature_response_is_identical_for_a_locked_and_an_unlocked_account` +now, against unmodified source. It must FAIL, and it must fail on assertion 1 with a diff whose +two sides differ by their leading template. Record that failure output verbatim in the SUMMARY -- +it is the non-vacuity evidence `05-VALIDATION.md` requires for every row. + +**Step 2 -- the fix.** + +In `ResetBarCodeForm.handleSubmit`, in the `if is_account_locked(user):` block only, change the +wrapper passed to `IStatusMessage(self.request).addStatusMessage` from +`_("Resetting of the bar-code failed! {0}".format(reason))` to +`_("Setup failed! {0}".format(reason))`. That is the entire behavioural change: one template +identifier on one line. Everything else in the block is unchanged -- the same +`reason = _("Invalid token or token expired.")`, the same `'error'` level, the same bare `return`. + +Do not move the block. Do not touch the `if not user:` branch or the `is_site_local_user` branch, +both of which keep `Resetting of the bar-code failed! {0}` and both of which remain +distinguishable by operator decision P5-17. Do not touch the invalid-reset-token branch inside the +`try`, which also keeps that wrapper. Do not add, move or wrap a `try:`/`except`. Do not move, +duplicate or wrap `reset_failed_second_factor` or `register_failed_second_factor`. + +i18n: both `Setup failed! {0}` and `Invalid token or token expired.` already exist as msgids in +`locales/imio.googleauthenticator.pot` and in the en, fr and nl `.po` files, and +`Resetting of the bar-code failed! {0}` is still used at three other call sites in this same file, +so it is not orphaned. Nothing under `locales/` changes and no `.mo` is regenerated. (Aside, so +the executor is not surprised by the test output: `_()` here wraps an already-interpolated native +string, so the runtime message never matches the catalogue msgid and the rendered text is plain +English. That is pre-existing throughout this file and `user_setup.py`, out of scope, and +unchanged by this plan.) + +**Step 3 -- the comment.** + +Replace the five-line comment currently sitting above the gate. As written it asserts the response +cannot be used to learn account state, which was false when it was written and is what +05-VERIFICATION.md's Anti-Patterns table flags as a blocker. A fix that leaves the lying comment in +place is not a fix. The replacement must: + +- say that this branch deliberately emits the same assembled wrapper and reason as the + wrong-code path does at the shared `reason is not None` tail at the bottom of the handler, and + that the two must be changed together or the lock becomes readable again; +- name `validate_token` and state that the gate stays ahead of it, so a locked account never + reaches TOTP arithmetic; +- cite MFA-08; +- state the limit honestly: this makes a locked account indistinguishable from an unlocked, + enrolled one, and does NOT make either indistinguishable from a username that does not exist or + from an account defined outside this Plone site -- those two branches above keep their own + messages by decision P5-17. + +Write that comment in your own words. Do not quote either message template verbatim inside it -- +name the tail structurally ("the shared `reason is not None` tail") instead. A comment carrying a +message literal breaks the source-count criterion below. + +**Step 4 -- rerun and record.** + +Run `bin/test -t test_reset_bar_code`, then `bin/test -t '!robot'`. Then add a row to +`05-VALIDATION.md`'s Per-Requirement Verification Map: `MFA-08 (not an oracle, reset path)`, Plan +`05-05`, Wave `1`, Threat Ref `T-05-23`, naming this test method and its file. Add a row rather +than overloading the existing `MFA-08 (reset path)` row -- that one is the lockout-threshold +predicate with a different test. + + + bin/test -t test_no_signature_response_is_identical_for_a_locked_and_an_unlocked_account + bin/test -t test_reset_bar_code + bin/test -t '!robot' + + + - `bin/test -t test_no_signature_response_is_identical_for_a_locked_and_an_unlocked_account` passes. + - **The oracle-property criterion:** that test's first assertion is an `assertEqual` between two lists of rendered status messages captured from two real anonymous `Browser` POSTs against the same account in the locked and the unlocked state. Message EQUALITY, not substring containment, not a `grep -c` on a message literal, and not a comparison of embedded reasons. + - The same test additionally asserts `unlocked == other_unlocked` (control) and `locked == other_unlocked` (the `missing[1]` contract), in that order, across two distinct accounts. + - Non-vacuity, recorded verbatim in the SUMMARY: the test was run against unmodified source before step 2 and FAILED on the locked-vs-unlocked assertion, with the reported difference being the leading message template. + - `bin/test -t '!robot'` reports 84 tests, 0 failures, 0 errors, and passes twice in a row (proving `tearDown` cleared the lock rather than gating a later class sharing the layer). + - `grep -c 'def test_' src/imio/googleauthenticator/tests/test_reset_bar_code.py` returns 2, and `git diff src/imio/googleauthenticator/tests/test_reset_bar_code.py` adds one `def test_` while modifying no existing method body. + - The new method's URLs contain neither `signature` nor `auth_timestamp`, and its `Browser` objects were never passed to `_login_browser`. + - Line order inside `handleSubmit`, read with `grep -n`: the `is_account_locked(` line number is less than the `validate_token(` line number. MFA-08's "lock before token" half survives the change. + - Source count, comment-immune: `grep -v '^\s*#' src/imio/googleauthenticator/browser/forms/reset_bar_code.py | grep -c 'Setup failed'` returns 2 (the locked branch and the shared tail), and the same filtered pipeline counting `Resetting of the bar-code failed` returns 3 (user-not-found, non-site-local, invalid-reset-token). + - `git diff src/imio/googleauthenticator/browser/forms/reset_bar_code.py` shows the comment above the gate replaced with new text rather than relocated, and the new text contains the identifier `validate_token` and the string `MFA-08`. + - `git diff` shows zero changed lines containing `register_failed_second_factor`, `reset_failed_second_factor`, `try:` or `except`. + - `git diff --name-only`, run from the repo root, lists exactly these three full repo-relative paths and no others: `src/imio/googleauthenticator/browser/forms/reset_bar_code.py`, `src/imio/googleauthenticator/tests/test_reset_bar_code.py`, `.planning/phases/05-drift-replay-and-lockout/05-VALIDATION.md`. It must NOT list `src/imio/googleauthenticator/browser/forms/token.py`, `.../user_setup.py`, `.../pas_plugin.py`, `.../subscribers.py`, `.../helpers.py`, or anything under `src/imio/googleauthenticator/locales/`. + - `test_reset_bar_code_lockout_after_five_failures` passes unmodified (`bin/test -t test_reset_bar_code_lockout_after_five_failures`). + - `05-VALIDATION.md` carries an `MFA-08 (not an oracle, reset path)` row naming this test method with `Plan` set to `05-05`. + + An anonymous caller who supplies nothing but a username at `@@reset-bar-code` cannot tell a locked account from an unlocked, enrolled one; a locked account still never reaches `validate_token`; and the comment above the gate now describes what the code actually does. + + + + +## Known, unaddressed -- recorded, not fixed + +| Finding | Location | Operator decision | +|---|---|---| +| `@@reset-bar-code` still discloses whether a username exists.

Carry both rows above into `STATE.md`'s Blockers/Concerns at phase close so +they survive into a later phase. + + +## Trust Boundaries + +| Boundary | Description | +|----------|-------------| +| anonymous HTTP -> `@@reset-bar-code` | The breached boundary. `configure.zcml` line 41 registers this view `permission="zope2.View"`, and `handleSubmit` performs no signature check of any kind -- `validate_user_data` is called only in `updateFields`, a render-time path whose result the POST handler never consults. Everything `handleSubmit` discloses is disclosed to an unauthenticated party who supplied only `auth_user`. This is a strictly weaker attacker than CR-01's at `token.py`, where at least a `validate_user_data` call existed to move the gate behind. | +| `handleSubmit`'s failure branches -> the rendered page | The only channel this plan changes. Four branches emit an error; two of them (`user not found`, non-site-local) intentionally remain distinguishable per P5-17, and two of them (locked, wrong code) are made identical. | +| `handleSubmit` -> `portal_memberdata` | Unchanged and deliberately so. The counter writes stay outside the broad `except Exception` block on this committing view path (MFA-12, plan 05-03's T-05-06).

The first half was true of the embedded `reason`; the second half was false, because the two branches wrap that shared reason in two different top-level templates ~45 lines apart. Its acceptance criterion -- `grep -c 'Invalid token or token expired'` == 2 -- could only ever have checked the half that was true, so the claim was never verifiable by the evidence offered for it. Re-rated `high`, matching T-05-18's rating for the structurally identical defect at `token.py` that this phase already treated as blocking, and matching 05-VERIFICATION.md's own BLOCKER disposition. **What makes the new mitigation verifiable, and the old one not:** Task 1's acceptance criterion is an executable test asserting EQUALITY of the full ordered list of assembled, user-visible status messages captured from real anonymous `Browser` POSTs -- the exact artifact the attacker sees -- rather than a substring count over source. It is required to be observed failing against unmodified source before the fix lands. | +| T-05-24 | Elevation of Privilege | the gate's position relative to `validate_token` | high | mitigate | Over-correcting -- moving or deleting the gate while changing its message -- would let a locked account keep consuming TOTP arithmetic against its stored seed at an anonymously reachable endpoint, defeating the lockout while the message-level oracle looked closed. Mitigated by the `is_account_locked(` < `validate_token(` line-order acceptance criterion, by a `must_haves` prohibition, and by `test_reset_bar_code_lockout_after_five_failures` remaining green unmodified. | +| T-05-25 | Tampering (of the control itself) | `register_failed_second_factor` / `reset_failed_second_factor` call sites in this handler | high | mitigate | Relocating either call, or drawing a `try:`/`except` around the edited region, would put a counter write on a path this file's broad `except Exception` can swallow -- a lockout that silently never locks, the exact failure mode PROJECT.md's security constraint names and plan 05-03's T-05-06 fenced against. Mitigated by a zero-changed-lines acceptance criterion on both identifiers and on `try:`/`except`, plus the existing `test_failed_attempt_counter_survives_unauthorized_request` and `test_no_second_factor_state_written_from_the_plugin`. | +| T-05-26 | Information Disclosure | the `user not found` and `is_site_local_user` branches | medium | accept | An anonymous caller can still learn whether a username exists, and whether an existing account is site-local, from the two distinct messages above the gate. Pre-existing (both branches predate Phase 5), distinct from the lock-state oracle closed here, and accepted by explicit operator decision P5-17 taken this session. Bounded in practice by the shared lock this phase added -- five wrong codes still lock the named account -- though that does not bound the *existence* probe itself, which needs no code submission. Recorded in **Known, unaddressed** above and to be carried into `STATE.md` Blockers/Concerns rather than silently dropped. Not `high`, because the disclosed fact is username existence, which this Plone site already discloses through `@@request-bar-code-reset` and standard member lookups, not the state of a security control. | +| T-05-27 | Information Disclosure | the message channel after the fix, residual | low | accept | With the two wrappers identical, the locked and wrong-code legs still differ internally: the wrong-code leg calls `register_failed_second_factor` and writes a memberdata property, the locked leg returns without writing. The resulting timing and write-volume difference is theoretically observable. It is dominated by Zope request overhead, by the `ska` HMAC `updateFields` performs on every one of these requests, and by ZODB commit noise, and is not measurable across a network at the precision needed. Accepted rather than silently ignored; no mitigation task. | +| T-05-SC | Tampering | dependency declarations | low | accept | No package is added, removed or upgraded by this plan. `setup.py`, `test-4.3.cfg` and `requirements-4.3.txt` are untouched, so no `[ASSUMED]`/`[SUS]` package legitimacy checkpoint applies. | + + + +**Signals:** the deterministic detector returned `detected: true` on two `pluralization` matches -- +`second` and `another`. + +**Primary noun:** account. One request, one `auth_user`, one account, one lock, one message. + +**Decision:** `no-change`. + +**Rationale:** both hits are prose false positives -- `second` matched inside the domain term +*second factor*, and `another` matched inside *another asserts a code already consumed...* in a +success criterion. Neither is a singular-to-plural identity transition. This plan changes one +message template and adds one test; nothing in the identity or cardinality model moves. + + +## Edge-probe accounting + +No `SPEC.md` exists for this phase, so neither `## Edge Coverage` nor `## Prohibitions` is +available (EDGE_ABSENT, PROHIB_ABSENT).

The probe derived nothing usable; 05-VERIFICATION.md's two `missing[]` +predicates are strictly more precise than anything it could have produced, so the `must_haves` +above are authored from those instead. A reviewer should still eyeball the edges the probe would +have been expected to name at this endpoint: an empty `auth_user`, a `auth_user` naming a +Zope-root account, and a locked account whose lock epoch has just expired between the GET and the +POST. + +**Accounting:** probe-surfaced items = 1. Authored into `must_haves` = 0. Surfaced as flagged +assumptions = 1. Sum = 1.

Drift and replay are naturally the same six lines, exactly as the roadmap says, but they need +one piece of state `onetimepass` doesn't manage: the last-accepted interval.** +`get_hotp(secret, intervals_no=i)` (confirmed at `onetimepass/__init__.py`, `get_hotp` function) is +a pure, stateless function: HMAC-SHA1 over `struct.pack('>Q', intervals_no)`, dynamic truncation, +mod 1,000,000. Accepting the immediately-preceding step means comparing the submitted token against +`get_hotp(secret, intervals_no=current)` and `get_hotp(secret, intervals_no=current-1)` **only** — +never `current+1`, since accepting a future code makes no sense for TOTP and the phase notes +explicitly warn against "widening the window forward". `onetimepass.valid_hotp` cannot be reused for +this: its `last`/`trials` parameters search **forward** from `last+1`, which is the opposite +direction (HOTP resync semantics, not TOTP drift), and it has no concept of "the interval before +now" at all. Replay rejection needs one integer of state — the last interval that was actually +matched and accepted — compared with `<=` against any newly-matched interval. Storing this single +integer (not a list of consumed codes) is what the roadmap's research question 2 asks for, and it +is what keeps the property bounded and cheap to validate. + +**3. `MutablePropertySheet`'s type-checking is stricter, and its failure mode more specific, than +"round-trips or doesn't" — read directly from `Products.PlonePAS==5.1.1`'s installed source** +(`Products/PlonePAS/sheet.py`, and `Products/PlonePAS/tools/memberdata.py::setMemberProperties`): +the type registered for a property is enforced by `PropertySchema.validate`, and for `'int'` that +inspector is exactly `lambda x: x is None or isinstance(x, int)` — a Python 2 `long` or a `float` +value **fails validation and raises `PropertyValueError`**, it does not silently coerce. `int(x)` on +a value already `< sys.maxint` (true for any Unix epoch for centuries on this 64-bit interpreter) +returns a genuine `int`, so `int(time.time())` is safe to store as `type="int"`; passing `time.time()` +itself (a `float`) would not be. Separately, and this is the "silent" failure CLAUDE.md/MFA-13 warn +about: `MemberData.setMemberProperties` (not the plural `MutablePropertySheet.setProperties`, which +this codebase's call path never reaches) loops `for k, v in mapping.items(): for sheet in sheets: if +not sheet.hasProperty(k): continue` — a key absent from every property sheet's declared property +list is **silently skipped**, no exception, no log line, and `modified` simply never becomes `True` +for that key. This is the exact mechanism `memberdata_properties.xml` entries prevent, and it is why +every new property in this phase needs both the XML entry and a `setMemberProperties()` → +`getProperty()` round-trip test, per MFA-13. + +Two more mechanical findings shape the plan directly. First, `` in the +existing `profiles/default/registry.xml` carries **no explicit field list** — confirmed by reading +`plone.app.registry`'s `RegistryImporter.importRecords` (installed at +`/home/cadam/buildout-cache/eggs/plone.app.registry-1.2.5-py2.7.egg/plone/app/registry/exportimport/handler.py`), +which iterates every field the *Python* interface declares and seeds a record with the schema's +default when the XML supplies no override. Adding two `zope.schema.Int` fields to +`IGoogleAuthenticatorSettings` therefore needs **zero `registry.xml` changes** — the existing blanket +`` line already covers them. Second, `helpers.validate_token` is called +from **three** views, not one: `browser/forms/token.py` (the login second factor), but also +`browser/forms/reset_bar_code.py` and `browser/forms/user_setup.py` (enrolment self-test and +bar-code-reset identity confirmation). REQUIREMENTS.md and ROADMAP.md phrase every lockout success +criterion around "the token form view" (singular), so the recommended split is: put the *format + +drift + replay* correctness fix inside shared `helpers.validate_token` (it is correct everywhere a +TOTP code is checked, and none of the three call sites end in an aborted transaction, so a state +write there does not reopen MFA-12), but keep the *lockout counter and 900s lock* strictly inside +`browser/forms/token.py::handleSubmit`, matching the phase's own literal scope. This is flagged as +Open Question 1 below since it is a scope decision, not a mechanical fact. + +**Primary recommendation:** Implement drift+replay as a small, pure `helpers.py` function built +directly on `get_hotp` (two calls, `current` and `current-1`, compared to `int(token)`), gated by a +new exact-6-digit format check that does not depend on or patch `onetimepass`. Track replay state as +a single `two_factor_authentication_last_interval` `int` memberdata property, updated only on +successful validation. Implement the lockout counter and 900s lock as two more `int` memberdata +properties (`two_factor_authentication_failed_attempts`, +`two_factor_authentication_locked_until`), written only from `browser/forms/token.py::handleSubmit`, +with the lock check running and short-circuiting before `validate_token` is ever called.

The only genuinely new code is +the small format gate and the interval-comparison loop — both a handful of lines each, not new +abstractions. + +## Common Pitfalls + +### Pitfall 1: Conflating `onetimepass`'s internal token-format check with this package's own code +**What goes wrong:** A plan reads ROADMAP.md's "`_is_possible_token` currently accepts `"1"` and +`"123"`" and goes looking for that function in `helpers.py` or `pas_plugin.py` to edit. +**Why it happens:** The name is written as if it belongs to this codebase; it does not — `grep -rn +"_is_possible_token" src/` returns nothing in this package. +**How to avoid:** The fix is a **new** check in `helpers.py`, run before `onetimepass` is ever +called, not an edit to a third-party pinned egg. +**Warning signs:** Any diff that touches `/srv/cache/eggs/onetimepass-*` or that imports +`onetimepass._is_possible_token` directly (it is not part of `onetimepass.__all__` and is not a +supported import). + +### Pitfall 2: Zero-padding trap in the existing SEC-01 regression test +**What goes wrong:** `test_helpers.py::TestSeedEncryption::test_seed_encryption_round_trip` calls +`validate_token(get_totp(seed), user=user)` where `get_totp(seed)` (with the library's default +`as_string=False`) returns a **bare, non-zero-padded `int`** — e.g. `42`, not `"000042"` — because +`get_totp`/`get_hotp` compute `token_base % 1000000` and return it as an `int` with no `str.zfill`. +Once MFA-07's exact-6-digit gate lands, this existing test's own construction will fail the new +format check on any interval where the true TOTP value happens to need fewer than 6 digits (a +roughly 1-in-10 chance per attempt, since leading digits 0-8 out of 0-9 keep it at 6, but a leading +zero drops a digit), making this a real, load-bearing, test-breaking change, not a hypothetical. +**Why it happens:** A real Google Authenticator app always zero-pads what it *displays* to 6 +characters; `get_totp(seed)`'s bare-`int()` return value used directly in a test does not. +**How to avoid:** Update that call site to `get_totp(seed, as_string=True)` (already zero-padded +to 6 bytes) — or format the int with `'{:06d}'.format(...)` — as part of *this* phase's changes, +not as a surprise regression discovered later. This is a required, in-scope test fix, not an +incidental side effect to shrug off. +**Warning signs:** `test_seed_encryption_round_trip` starts failing intermittently (only on seeds +whose current TOTP value is under 100000) after the format gate lands, with no code change to that +test file itself. + +### Pitfall 3: `MutablePropertySheet`'s type check rejects `float`/`long`, it does not coerce +**What goes wrong:** Writing `user.setMemberProperties(mapping={'two_factor_authentication_locked_until': +time.time() + lockout_duration})` raises `PropertyValueError` inside `MutablePropertySheet.setProperty` +(reached via `MemberData.setMemberProperties` → `sheet.setProperty(user, k, v)` → +`self.validateProperty(id, value)`), because `time.time()` is a `float` and the `'int'` type +inspector is `isinstance(x, int)`. +**Why it happens:** The property-type validator does not attempt any numeric coercion; it is a +strict `isinstance` check per type (confirmed at +`Products/PlonePAS/sheet.py::PropertySchema`). +**How to avoid:** Always wrap with `int(...)` before the write: `int(time.time()) + lockout_duration` +is itself an `int` (int + int = int in Python 2), safe to store. +**Warning signs:** `PropertyValueError` raised inside a `handleSubmit`, swallowed by the existing +broad `except Exception:` blocks in `token.py`'s sibling forms (`user_setup.py`, `reset_bar_code.py`) +— which would turn a broken lockout write into a silent no-op with a generic "unexpected error" +message, exactly the "looks like it works" failure mode this whole phase exists to prevent. Do not +wrap the new lockout-write code in a broad `except Exception` for this reason: let a +`PropertyValueError` surface loudly during development rather than mask a real property-declaration +bug. + +### Pitfall 4: Silent memberdata-property drop, not an exception +**What goes wrong:** A new memberdata property is used in code (`getProperty`/`setMemberProperties`) +but its `memberdata_properties.xml` entry is forgotten. `MemberData.setMemberProperties`'s +`if not sheet.hasProperty(k): continue` means the write for that key is **silently skipped** across +every property sheet — no exception, no log line, `getProperty` keeps returning the schema field's +Python-level default (`''`/`False`/whatever `getProperty`'s own default fallback is) forever. +**Why it happens:** `setMemberProperties` is designed to tolerate keys aimed at a *different* +property sheet (e.g. a mapping containing both memberdata and a different plugin's properties) — the +`continue` is correct behaviour for that case and indistinguishable from "declaration forgotten" from +the caller's point of view. +**How to avoid:** The `memberdata_properties.xml` entry and the round-trip test +(`setMemberProperties` then `getProperty` returns what was set, not the default) must land in the +**same commit** as the code that starts writing the property, exactly as MFA-13 requires. +**Warning signs:** A lockout that "never locks" or a failure counter that always reads back `0` +with no error anywhere in the logs — this is precisely the Phase 4 "silent risk" pattern ROADMAP.md +calls this project's dominant risk category. + +### Pitfall 5: Scope creep of the lockout write beyond `browser/forms/token.py` +**What goes wrong:** `helpers.validate_token` is also called from `browser/forms/reset_bar_code.py` +and `browser/forms/user_setup.py`. If the failure-counter/lockout logic is embedded inside +`validate_token` itself rather than wrapped around it in `token.py`, a wrong code during **enrolment +self-test** or a **bar-code reset** attempt would also count toward — and potentially trigger — the +account lockout that MFA-08's success criteria describe entirely in terms of "the token form". +**Why it happens:** `validate_token` is the one shared function all three views call, making it the +tempting single insertion point for "any place a code is checked." +**How to avoid:** Keep the format+drift+replay **check** (and its `last_interval` state write, which +is a correctness fix, not a security policy choice, and is safe in all three normally-committing +views) inside `helpers.validate_token`. Keep the **lockout counter and 900s lock** — the specific +policy MFA-08/09/10/11 describe — as a wrapper in `browser/forms/token.py::handleSubmit` only.

The +only gates before `validate_token`/`register_failed_second_factor` are `api.user.get(username= +username)` resolving and `is_site_local_user`/`is_account_locked`. An anonymous POST to +`@@reset-bar-code?auth_user=` with five wrong six-digit +`form.widgets.token` submissions requires no password, no `ska` signature and no +`auth_timestamp` -- nothing beyond the username itself -- and locks that account's second +factor for `lockout_duration` (default 900s). + +`tests/test_reset_bar_code.py::test_reset_bar_code_lockout_after_five_failures` proves this +is deliberate and *bounded* for a single account (its own docstring names it "the defect +being metered", bounded by `lockout_duration`, decisions T-05-08/P5-13). What neither that +test nor the design bounds is the aggregate case: nothing here rate-limits by IP or session, +so a single anonymous actor can iterate a list of known/guessed usernames and drive every +one of them through the same five-submission sequence, locking the entire enrolled user +base's second factor at once and re-triggering it every `lockout_duration` seconds +indefinitely. This is asymmetric with `token.py`'s login path, where reaching +`is_account_locked` first requires a valid `ska`-signed URL -- i.e. the attacker must already +possess that specific user's password -- so the login path cannot be used to mass-lock +accounts the attacker has not already compromised. `reset_bar_code.py` is the one path that +can, by design, at zero authentication cost. + +**Fix:** A signature requirement can't be added here without breaking the already-tested +MFA-11 guarantee that a *correct* code at this endpoint clears the counter/lock even with no +signature supplied (`test_reset_bar_code_lockout_after_five_failures` step 2 depends on +exactly that). The narrower fix is a rate limit in front of the per-account counter that +doesn't touch that guarantee -- e.g. an IP- or session-scoped throttle on `@@reset-bar-code` +POSTs, independent of which `auth_user` is named: + +```python +# reset_bar_code.py, ResetBarCodeForm.handleSubmit, before validate_token is ever reached +if not within_ip_rate_limit(self.request): + reason = _("Too many attempts, please try again later.") + IStatusMessage(self.request).addStatusMessage( + _("Setup failed! {0}".format(reason)), 'error') + return +``` +(The rate-limit state itself needs the same memberdata-vs-RAM-cache consideration CLAUDE.md +already documents for the per-user counter -- a per-instance cache would let an attacker +multiply attempts by rotating ZEO clients.)

The documented short-circuit applies — +`threats_open: 0` with the register authored at plan time at level 1 — so no auditor subagent was +spawned.

The +embedded reason was indeed shared, but the two branches wrapped it in different top-level +templates about 45 lines apart, and the acceptance criterion offered — a substring count of +`Invalid token or token expired` — could only ever check the half that was true. A register that +has been wrong once in exactly this way should not be re-blessed by confirming that the named +tests exist. The three structural mitigations were therefore checked against current source: + +- Lock evaluated before token arithmetic: `is_account_locked` at `token.py:108` precedes + `validate_token` at 113; at `reset_bar_code.py:123` precedes 132. +- Counter writes outside the broad `except Exception` in `reset_bar_code.py`: + `reset_failed_second_factor` at line 145 precedes `try:` at 146, and + `register_failed_second_factor` at 170 follows `except Exception:` at 166. +- No second-factor state write in a non-committing path: zero matches for the three counter + property names and three helper function names in `pas_plugin.py` and `subscribers.py`. + +All 13 tests cited as mitigation evidence exist, and the full suite passes: 90 tests, 0 failures, +0 errors under `bin/test -t '!robot'`. + +**End-to-end confirmation from UAT.** Two threats were additionally confirmed on a live +`server.dmsmail` deployment behind the real front-end proxy, which no in-process test can do: +T-05-18 (UAT test 4) and T-05-23 (UAT test 5). Both produced responses identical but for the +`Date` header, with matching status line, `Content-Length`, `Expires` and `Set-Cookie`. UAT test 1 +also confirmed T-05-07's premise on real hardware: the failure counter is shared across four ZEO +clients, so it is not a per-instance RAM count an attacker could multiply by rotating clients. + +### Changes landing after `05-VERIFICATION.md` was written + +Three code changes landed during UAT, after the verification report.

Zope then reads + `@@google-authenticator-token\` as the view name and the remainder as path, which resolves to + nothing.

The URL needs no backslash when it is already single-quoted for the shell. + + Two hypotheses were raised before that and both are disproved, recorded so neither is + revisited: the view name or site path being wrong (it was neither -- the path was correct + apart from the backslash), and the instance on port 8084 not loading the package. On the + latter, `bin/instance1` through `bin/instance4` all reference + `/srv/src/server.dmsmail/src/imio.googleauthenticator/src`, and `port.cfg` maps 8081 to 8084 + to instances 1 to 4, so every instance loads it. +attempt_2: + date: 2026-08-03 + outcome: inconclusive, evidence rejected + method: | + Same two requests with the backslash removed.

The lock gate is at `token.py:108`, inside `handleSubmit`, which is the + `@button.buttonAndHandler(_('Verify'))` handler declared at `token.py:64`. z3c.form runs a + button handler only when the form is submitted, so a GET carrying just `auth_user` renders the + form and reaches neither `validate_user_data` nor `is_account_locked`. Two identical 200s + therefore show only that the form page renders identically, which is weaker than the + requirement. The in-process test does a real POST: `_submit` in `tests/test_reset_bar_code.py` + fills `form.widgets.token` and clicks `Verify`. + + This was the second incorrect instruction issued for this test, after the backslash run.

Details: Invalid signature!`. That is the message emitted where + `validate_user_data` fails in `token.py`, immediately followed by `return`, which sits ABOVE + the lock gate at line 108. Execution therefore stopped at signature validation and never + consulted the lock. + why_this_is_a_pass: | + Stronger than message equality between two lock branches: the response shows the unsigned + request returning before any lock logic is reached, so lock state cannot have influenced it + whatever that state was. This is precisely what plan 05-04 set out to achieve by moving the + gate to run after signature validation.

Neither is a Phase 5 requirement failure — Phase 5 covers clock drift, +replay rejection, lockout, lock-state indistinguishability and counter persistence (MFA-05 +through MFA-13), and `05-VERIFICATION.md` scored 19/19 on those. Recorded here so the +observations are not lost, and deliberately kept out of `## Gaps` so they do not block this +phase or spawn Phase 5 gap-closure plans. + +### F-1. No JavaScript runs at all on the deployment — cause found, FIXED in 452b66c + +Resolved after this section was first written, and since confirmed working on the affected +`server.dmsmail` site by the operator on 2026-08-03 after re-importing the profile's `jsregistry` +import step: overlay forms render as overlays again. + +The operator read the live registry order off the +affected site on 2026-08-03: `++resource++imio.googleauthenticator/main.js` 1st, +`++resource++imio.googleauthenticator/plone_ecmascript/popupforms.js` 2nd, +`++resource++plone.app.jquery.js` 3rd. + +Root cause: `profiles/default/jsregistry.xml` declared no position directive, and +`Products.ResourceRegistries` 2.2.13 `BaseRegistry.storeResource` simply appends, so the final +order depended on when the profile's import step ran. Installing onto an existing site appends +after Plone's registrations and works, which is exactly why the integration test layer showed +these two at positions 42 and 43 and never reproduced the fault. On a fresh site, where +GenericSetup can import this step before Plone registers jQuery, they landed at 0 and 1. Cooking +merges adjacent compatible resources into one bundle, so the `$ is not defined` thrown by +`main.js`'s top-level `$(document).ready(...)` aborted that bundle before jQuery defined itself, +and every jQuery-dependent script on the site failed. + +Fix: `insert-bottom="True"` on both entries, which also repairs an already-broken site on +profile re-import because the importer applies the move to existing resources too. Regression +test `test_every_javascript_registration_pins_its_position` in `tests/test_setuphandlers.py` +parses the XML and fails if any registering entry omits a position directive; confirmed to fail +when the directives are stripped. Suite: 90 tests, 0 failures. + +The original analysis, kept because two of its hypotheses were wrong and the record of why +matters: + + + +Observed: the user-actions view does not open under the logged-in user's name, and `@@new-user` +opens a full page. Both should open in Plone's overlay. + +The browser console (supplied 2026-08-03) shows this is not an overlay problem. Roughly twenty +errors fire on one page load, all of the form `$ is not defined` or `jQuery is not defined`, +across packages with nothing to do with this one: Plone's own `table_sorter.js`, +`collective.js.fancytree`, `ckeditor_vars`, `plonetheme.imioapps`, `collective.contact.plonegroup`, +`imio.actionspanel`, `plone.formwidget.autocomplete`, and inline scripts in `useractions` itself. + +**jQuery is absent from the page.** Overlays cannot work as a consequence — `prepOverlay` is a +jQuery Tools plugin and cannot exist without jQuery — so the full-page forms are a symptom, not +the defect. This package's `browser/static/main.js` is merely the first victim in console order: +it calls `$(document).ready(...)` at top level, so it is among the first scripts to touch `$`. + +Two hypotheses were formed and both were rejected on evidence: +- A `jQuery.browser` TypeError in the vendored `popupforms.js` aborting the ready handler before + any `prepOverlay` call. Rejected: both this buildout and `server.dmsmail` resolve + `plone.app.jquery 1.7.2.1`, where `jQuery.browser` still exists. +- This package's resources being registered above jQuery. Rejected: + `Products.ResourceRegistries` 2.2.13 `BaseRegistry.storeResource` appends + (`resources.append(resource)`), and this package's `jsregistry.xml` gives no `insert-before` / + `insert-after` / `insert-top` directive, so its entries land at the bottom of the registry. + +What is still unknown is why jQuery itself is not on the page, which cannot be determined from +the repository. It needs the live state of `/portal_javascripts/manage_jsForm` on the affected +site: whether the jQuery resource is present and enabled, and its position. + +Separately, and independent of the above, two real defects in this package were confirmed by +reading source. `profiles/default/jsregistry.xml` carries ``, which unregisters Plone's core overlay script site-wide with no +uninstall counterpart, and substitutes `browser/static/plone_ecmascript/popupforms.js`, a stale +fork that against Plone 4.3.20 uses the old `jQuery.browser` API instead of the `msieversion()` +helper, drops `dl.portalMessage.warning` from `common_content_filter`, and comments out the +login-form overlay (lines 60-85, the only intentional change). The package also replaces Plone's +`login_form.cpt` through a skin layer. Both override resources this package does not own. + +Routing: no new item filed. ROADMAP Phase 7 already covers all of it — Success Criterion 2 names +the `remove="True"` line as "a global mutation with no uninstall counterpart, and it is why the +collision flips on install order", Success Criterion 3 requires a real `profiles/uninstall/`, and +the Phase 7 notes already record both stale-copy differences. Whether the missing jQuery is also +Phase 7's is undecided until the registry state is known. + +### F-2. Bar-code reset request landed on the login page — FIXED, commit a14b012 + +Observed: logging in prompted for a one-time code; with no code available the user followed the +bar-code reset link, submitted their username, and arrived at the login page rather than at a +reset view. + +Root cause: `browser/forms/request_bar_code_reset.py` redirected to the portal root after +sending the reset email. The caller arrives from the token form, by which point the PAS plugin +has cleared their `__ac` cookie, so they are anonymous; on a site whose root is not anonymously +viewable that redirect lands them on the login form, and the "email sent" confirmation is never +read. Present since the initial upstream import (`4faeac2`); no test covered the redirect +target. Phase 5 never touched the file. + +Fix: the handler now returns without redirecting, re-rendering its own form — which is +registered `permission="zope2.View"` and so stays readable while anonymous — with the +confirmation on it, matching what its failure branch already did. Regression test +`test_successful_request_keeps_the_caller_on_the_form` asserts the response carries no +`Location` header and that the confirmation message is queued. Suite: 85 tests, 0 failures. + +Separate, not a defect: reaching the reset view directly is not the design. +`@@request-bar-code-reset` emails a signed link to `@@reset-bar-code`, and the signature in that +link is what authorises the reset. + +## Summary + +total: 6 +passed: 6 +issues: 0 +pending: 0 +skipped: 0 +blocked: 0 + +## Gaps + +- gap_id: G-05-A + truth: "Every memberdata property plan 05-01 added can be read and written without breaking any + user-profile form.

All four hold, per-account, regardless of who triggered the failures — the +criterion says nothing about *who is authorized to cause a lock*, only about the lock's behavior +once triggered. The mass-lockout DoS WR-01 describes is a distinct availability concern the phase's +own plan 05-03 explicitly named, bounded (`lockout_duration`, self-expiring), and accepted by +operator decision (T-05-08/P5-13, `05-03-PLAN.md`), and it is the same disposition the standing +`Out of Scope` table in REQUIREMENTS.md gives to "Admin-unlock-only lockout... a DoS primitive": the +project's own posture already treats a bounded, self-clearing lockout as an acceptable tradeoff +class. Tested (`test_reset_bar_code_lockout_after_five_failures` asserts the bound), documented +(05-REVIEW.md WR-01, this file), and reversible (an IP/session throttle is additive, not a redesign) +— a Warning, not a Phase 5 blocker. + +**WR-02 (the three new lockout/replay `Int` schema fields have no `readonly=True`; the personal +preferences form's `omit()` is the only barrier to self-editing today):** none of the five stated +Success Criteria concern schema-level write protection beyond what the current, actually-exposed UI +enforces — and the current UI (`CustomizedUserDataPanel.__init__`'s `omit()`) does enforce it today, +confirmed by the fact that no test or code path in this phase exposes an edit form for these fields +without that `omit()` applied. WR-02 names a *future* risk (a hypothetical consumer of +`IEnhancedUserDataSchema` that renders the schema without re-applying `omit()`), not a present +violation of any truth verified above. A Warning, not a blocker — `readonly=True` is a cheap, +independent hardening step worth taking opportunistically, but its absence does not make any of the +five Success Criteria false today. + +### Anti-Patterns Found + +| File | Line | Pattern | Severity | Impact | +|------|------|---------|----------|--------| +| `helpers.py` | 644, 672 | Pre-existing `FIXME` markers (dated 2014, predates this phase) | ℹ️ Info | Not introduced by phase 5; unrelated to lockout/drift/replay code | +| `browser/forms/token.py` | ~130 | Pre-existing `TODO` (dated 2015, predates this phase) | ℹ️ Info | Unrelated to phase-5 changes | +| `userdataschema.py` | 86-102 | New `Int` lockout/replay fields have no `readonly=True`; `omit()` is the sole barrier | ⚠️ Warning | WR-02, judged above — not a phase gap | +| `reset_bar_code.py` | 72-171 | Reset-form counter consumable with no signature check at all (accepted, bounded DoS) | ⚠️ Warning | WR-01, judged above — not a phase gap | +| `controlpanel.py` | 148-152 | Dead `disable_two_factor_authentication_for_users` fetch/import | ℹ️ Info | Pre-existing, unrelated to this phase | + +No unresolved `TBD`/`FIXME`/`XXX` markers were introduced by phase 5's own commits (all found +markers predate the phase, independently re-confirmed by grep in this pass). + +### Human Verification Required + +See the `human_verification` frontmatter list above (6 items, all traceable to explicit +`verification: backstop` truths recorded in the phase's own five PLAN.md files). These are runtime +claims about a real ZEO cluster, a real running control panel, a real mobile-app clock, and a real +front-end proxy — none of which the integration-test layer can exercise. `config.json` sets +`workflow.human_verify_mode: end-of-phase`, and this is that end-of-phase point: all five plans have +executed and the phase's last remaining code gap (the `@@reset-bar-code` oracle) is closed, so these +backstop items now surface rather than being deferred further. None of the six items describes a +code defect — each is present, wired, and covered by an in-process test that this verification +independently re-ran and confirmed passing; what remains is confirmation against real infrastructure +this test environment does not have. + +### Gaps Summary + +No gaps remain. The single BLOCKER carried by the prior verification cycle — the `@@reset-bar-code` +message-level lock-state oracle — is closed by plan 05-05 (commit `be31592`), independently +confirmed in this pass by direct source read, an isolated re-run of the new test, and a full-suite +re-run (84 tests, 0 failures, 0 errors).

Not "token". A token is one kind of second factor; a recovery +code is another. `token.py`'s call site is asking "did this caller present a valid second +factor?", not "did this caller present a valid TOTP token?". + +**Decision: `promote`.** + +The generalized representation becomes the primary caller-facing API and the old specific one is +demoted to a variant handler: + +- `helpers.validate_second_factor(token, user=None)` is the new primary. It is the only + second-factor validator `browser/forms/token.py` calls. +- `helpers.validate_token` is demoted to *the TOTP variant handler*. Its signature, body, + behaviour and test coverage are untouched, so all nine already-shipped Phase 5 requirements keep + their verbatim assertions and nothing churns. +- `helpers.validate_recovery_code` is the recovery-code variant handler, a sibling of + `validate_token` rather than a branch inside it. + +**Rationale:** the promote is free here. The dispatcher does not exist yet, so choosing the +generalized name costs one naming decision and zero refactoring. `06-RESEARCH.md` proposes the +name `validate_token_or_recovery_code`, which is structurally the same promote wearing an +add-alongside name: it enumerates today's two variants in the identifier, so a third kind would +force a rename. **This plan supersedes that name.** Every reference in RESEARCH.md to +`validate_token_or_recovery_code` means `validate_second_factor`. + +**Not `add-alongside`,** even though the two-year lifespan would have excused it: an +add-alongside here would have meant `token.py` keeping an `if`/`else` over two validators, which +puts the dispatch decision in a view instead of in `helpers.py` and is the shape MFA-12 was built +to prevent state from living in. + +**Invariant test encoding the generalized intent** (plan 06-03 owns it): every accepted second +factor, of every supported kind, routes through the same `reset_failed_second_factor` call and +every refused one through the same `register_failed_second_factor` call -- asserted as *exactly +one* such call site per outcome in `token.py`. A future phase that reintroduces the singular +assumption by adding a second, parallel validation branch goes red immediately. + + + +The deterministic edge probe returned twelve rows over the seven RECOV requirements. Seven were +categorised and are resolved into `must_haves.truths` (six `covered`, one `backstop` -- see plans +01 and 02). **Five rows came back `unclassified` and are NOT resolved.** They are recorded here as +explicit assumptions rather than dropped, per the spec-less probe fallback rules; they were not +auto-`backstop`ed and were not auto-dismissed. + +| Requirement | Probe | Status | Assumption this plan proceeds on | +|---|---|---|---| +| RECOV-02 | unclassified -- review manually | unresolved | That "plaintext never stored" is fully discharged by asserting absence from the two new property values. It does **not** cover a plaintext code reaching the ZODB by some third route (a `plone.app.discussion` comment, a catalog index, an audit log). No such route exists today; nothing asserts one cannot be added. | +| RECOV-04 | unclassified -- review manually | unresolved | That "consumed on use" means removed from the stored hash list at the moment of acceptance, and that a code consumed in a request whose transaction later aborts is acceptably *not* consumed. The write lives in a view that returns 200/302, so this is the same MFA-12 reasoning Phase 5 settled, applied to a new writer. | + +RECOV-03, RECOV-05 and RECOV-07's unresolved rows are recorded in plans 06-02 and 06-03, which +own those requirements. + + + + + + Task 1: Settle the two one-way decisions -- PBKDF2 iteration count and storage shape + + Two values become effectively irreversible the moment a real user enrolls, because the + plaintext codes are gone by design and cannot be rehashed: + + 1. The PBKDF2-HMAC-SHA256 iteration count. + 2. The storage shape of the two new memberdata properties. + + + **Why one-way.** Changing the iteration count later means recomputing every stored hash, which + requires the plaintext codes, which are deliberately unrecoverable. The only migration is + "every enrolled user regenerates their whole set", i.e. invalidating every printed code every + user holds. Same for the storage shape: a stored hash list cannot be reinterpreted under a new + encoding without the plaintext. + + **Iteration count.** ROADMAP.md Phase 6 phase notes name this as the phase's one Open + Decision and pre-agree a 20,000-200,000 envelope, stating iterations are insurance rather than + the primary defence -- the codes are 80-bit CSPRNG values with no dictionary to walk, so the + entropy is the defence. `06-RESEARCH.md` measured this buildout's own Python 2.7.18 + interpreter this session: 20,000 = 0.022s, 50,000 = 0.054s, **100,000 = 0.117s**, + 200,000 = 0.229s.

This is the RECOV-01 input-validation gate and it + mirrors `_is_six_digit_token`'s existing precedent: run it before the KDF is ever reached, so + garbage input costs no PBKDF2 work. Membership is tested against the explicit RFC 4648 base32 + alphabet, which is uppercase-only -- normalization has already uppercased, so a lowercase + paste is accepted; a digit `0`, `1`, `8` or `9` is not in the alphabet and is refused. + + **Step 6 -- `_hash_recovery_code(code, salt)`.** One `pbkdf2_hmac('sha256', code, salt, + RECOVERY_CODE_PBKDF2_ITERATIONS)` call, returning `binascii.hexlify(digest)` -- 64 ASCII hex + characters. Both operands are ASCII-encoded to `str` first if they arrive as `unicode`, since + `getProperty` may hand back either. Do not hand-roll an iterated SHA-256 loop; do not reach + for `cryptography`'s `PBKDF2HMAC` class, which produces the same output with more ceremony + (RESEARCH § Don't Hand-Roll). + + **Step 7 -- `generate_recovery_codes(user)`.** Mint one salt as + `binascii.hexlify(os.urandom(RECOVERY_CODE_SALT_BYTES))` -- **one salt, singular, for the + whole set**. Mint `RECOVERY_CODE_COUNT` plaintext codes as + `base64.b32encode(os.urandom(RECOVERY_CODE_ENTROPY_BYTES))`, which yields exactly 16 + characters with no `=` padding because 80 bits is an exact multiple of base32's 5-bit block. + Hash each under the one salt. Write the salt and the hash tuple in **one** + `setMemberProperties` mapping call, so a regeneration cannot leave a new salt with an old hash + list. Return the plaintext list. Follow `generate_secret`'s shape exactly, including its + deliberate discipline that the plaintext is returned but never logged -- `generate_secret` + carries a commented-out `logger.debug(secret)` as a marker; do not uncomment it and do not + write an equivalent line for a code, a salt or a hash at any level. + + **Step 8 -- `validate_recovery_code(token, user=None)`.** Default `user` from + `api.user.get_current()` as `validate_token` does. Then, each gate returning `False` before + the next (`validate_token`'s exact discipline): normalize; refuse on shape; read the stored + salt and hash tuple with an `or ''` / `or ()` coercion, since `getProperty` returns `''` for a + Zope-root account with no property sheet; refuse if either is empty. Hash the submitted code + once. Walk the stored tuple with `enumerate`, comparing via the already-imported + `compare_digest` with both operands coerced to `str`. **On a match, remove the matched entry + by its index** -- `stored[:i] + stored[i+1:]` -- and write the shortened tuple with one + `setMemberProperties` call, then return `True`. Removing by index rather than by filtering the + tuple on inequality is load-bearing: an equality filter deletes *every* byte-identical entry, + so a birthday collision inside one ten-code set would silently burn two codes on one use. + Return `False` after the loop. The write happens only here, only on the accept path, inside + the helper -- never in the caller. Log nothing at all on the failure path. + + **Step 9 -- `validate_second_factor(token, user=None)`.** The promoted dispatcher; see this + plan's `` block for why this name and not RESEARCH.md's + `validate_token_or_recovery_code`. Default `user`, then: if `_is_six_digit_token(token)`, + delegate to `validate_token(token, user=user)`; if + `_is_recovery_code_shape(_normalize_recovery_code_input(token))`, delegate to + `validate_recovery_code(token, user=user)`; otherwise return `False`. Add no `if`/`elif` + branch inside `validate_token`'s own body -- its signature, behaviour and Phase 5 test + coverage stay byte-identical. + + **Step 10 -- swap the dispatch point in `token.py`.** Add + `from imio.googleauthenticator.helpers import validate_second_factor` to the existing + one-name-per-line import block at lines 18-24, in alphabetical position, and remove the now + unused `validate_token` import. Change **only** the right-hand side of the assignment at line + 113 so it reads `valid_token = validate_second_factor(token, user=user)`. Nothing else in + `token.py` changes: the lock gate at 108-111 stays exactly where 05-04 put it, and + `reset_failed_second_factor` at 120 / `register_failed_second_factor` at 140 already wrap this + one call site, which is how RECOV-05 becomes true with no new plumbing. Leave + `browser/forms/user_setup.py` and `browser/forms/reset_bar_code.py` calling `validate_token` + directly and unchanged -- both exist to prove current possession of the authenticator device, + and this phase is scoped to the token form per ROADMAP Phase 6's "the single dispatch point in + the token form" and RESEARCH Open Question 1. + + **Step 11 -- the end-to-end test.** Add one method to `TestTokenFormLockout` in + `tests/test_token.py`, named `test_recovery_code_is_accepted_in_place_of_a_token_and_consumed`, + covering all seven `` rows in one method per the project skill's R5 one-method-per- + function rule. Reuse `_enable_2fa`, `_get_browser`, `_login_browser` and `_submit_token` + verbatim -- `_submit_token` sets `form.widgets.token` and clicks Verify, and the `TextLine` + widget has no length constraint, so a 16-character value goes through the same path. Generate + the set by calling `helpers.generate_recovery_codes(user)` directly, then + `transaction.commit()` before the first `Browser.open` (the `_enable_2fa` docstring explains + why: a fresh ZPublisher transaction discards the test's own uncommitted writes).

No prior test in this file ever called `.render()` on the unwrapped `SetupForm` (existing tests only call `handleSubmit` directly and inspect response headers), so this was latent and unexercised until this plan's new test needed a real `render()` call, which drives Plone's standalone default form page template -- that template needs `request.RESPONSE` (unconditionally, in `main_template.pt`) and, via `z3c.form.form.Form.action`, `request.getURL()` (which needs `other['URL']`). +- **Fix:** In `_build_form`, after `self.request.other.clear()`: restore `other['RESPONSE'] = self.request.response`, restore `other['URL'] = self.portal_url` (a valid-enough URL for this fixture's purposes), and set `form.__name__ = 'setup-two-factor-authentication'` (mirroring what `plone.z3cform.layout.FormWrapper.__init__` does in production, avoiding one further `request.getURL()` call site in `plone.app.z3cform`'s macros). +- **Files modified:** `src/imio/googleauthenticator/tests/test_user_setup.py` (test-only; no production code touched) +- **Verification:** `bin/test -t test_user_setup` green (4 tests); re-ran `bin/test -t test_generic`, `test_pas_plugin`, `test_token` afterward to confirm the shared helper's changed behaviour didn't regress anything else using it. +- **Committed in:** `fdfde6c` (Task 3 commit) + +**3. `--no-verify` used on all three task commits** +- Per this plan's explicit `` instruction and the project's documented pre-existing 318-finding `bin/code-analysis` debt (CLAUDE.md, scheduled for Phase 8/QUAL-06).

It does **not** cover a future *third* endpoint that validates a second factor -- `@@reset-bar-code` is metered by Phase 5 but calls `validate_token`, not `validate_second_factor`, so it is metered for TOTP and does not accept recovery codes at all. A fourth endpoint added later would need its own metering, and nothing in this phase forces that. | +| RECOV-07 | unclassified -- review manually | unresolved | That "warned" means one `IStatusMessage` at the moment of consumption, per RESEARCH Open Question 2's recommendation. It does **not** provide a persistent indicator: a user who last used a recovery code months ago sees no reminder until they use another. RESEARCH recommends shipping the login-time message first and treating a `personal-information` viewlet as an optional enhancement; this plan follows that and does not build the viewlet. | +| RECOV-02 | unclassified -- review manually | unresolved | Recorded in plan 06-01.

Placing this inside the accept branch is what makes RECOV-07 + unreachable from a failed or anonymous attempt *by construction* rather than by a conditional + a later edit could invert -- the function has already decided the caller holds a genuine code + at that point. Do not queue anything on the failure path and do not queue anything before the + write. + + **Step 3 -- the message.** Build it with the module's existing `_` `MessageFactory` using a + **mapping**, not `str.format` inside `_()`: msgid + `u"Recovery codes remaining: ${remaining}. Generate a new set from your personal information page."` + with `mapping={'remaining': }`. Two reasons for the mapping form over this + codebase's older `_("... {0}".format(x))` habit: the msgid stays extractable by `i18ndude` + rather than being baked with a value, and phrasing the count as a trailing field sidesteps a + plural-form problem entirely (`Recovery codes remaining: 1` is grammatical; `You have 1 + recovery codes left` is not) with no plural machinery.

One wrong recovery code submission reads `two_factor_authentication_failed_attempts` back as + `1` through a fresh `api.user.get(username=...)`. + 2. A *mixed* run reaches the lock: after the first wrong recovery code, submit three wrong + six-digit codes and then one more wrong recovery code -- five failures of two kinds -- and + assert `two_factor_authentication_locked_until` is now greater than `int(time.time())` and + `two_factor_authentication_failed_attempts` is back to `0` (the lock write zeroes the + counter in the same call, per MFA-13/P5-05). The mix is the point: a counter that + distinguished the two kinds would need five of *one* kind and would not lock here. + 3. Non-vacuity control mirroring `test_lockout_after_five_failures`: assert that after only + four of those five submissions the lock epoch is still `0`, so the fifth-failure assertion + proves something. + 4. Clear the lock directly (`setMemberProperties` + `transaction.commit()`), submit a genuine + unused recovery code, assert the browser leaves `@@google-authenticator-token` and that both + the counter and the lock epoch read back `0` -- the success path resets through the same + `reset_failed_second_factor` call a TOTP success uses (MFA-11 for the new kind). + + **Method 2 -- `test_low_recovery_code_count_warning`** (RECOV-07). Enroll, generate a set, + commit. Consume codes one at a time through `_submit_token`, opening a fresh browser and + re-logging-in for each consumption (a successful submission logs that session in, so it cannot + submit again -- the existing `test_successful_second_factor_resets_failed_attempts` already + hits this and solves it with a second browser). Assert: + 1. While five and then four codes remain, the rendered page carries no message containing + `Recovery codes remaining:`. + 2. On the consumption that leaves exactly three, the rendered page carries a message containing + `Recovery codes remaining:`, and it is a `warning`-class message (extract it with a + `portalMessage warning` variant of this file's existing `message_re` regex). Assert the + stored hash count is `3` separately, through `getProperty`, rather than relying on the + interpolated number appearing in the markup -- `zope.i18n`'s `${remaining}` substitution on + an untranslated msgid is one indirection this assertion does not need to depend on. If the + rendered text does happen to carry the number, assert that too as a bonus, but do not make + the test hinge on it. + 3. Three-and-four is the adjacency boundary and both sides are asserted, matching the + `MFA-13 adjacency` convention this file already uses for the lock epoch. + 4. A *failed* submission at four remaining renders no `Recovery codes remaining:` text -- + RECOV-07's oracle half, and the assertion that pins T-06-04. + 5. An anonymous caller, using this file's existing no-signature idiom (open + `@@google-authenticator-token?auth_user=` on a browser that was never + `_login_browser`-ed, then submit), renders no `Recovery codes remaining:` text. + + **Method 3 -- `test_second_factor_dispatch_has_exactly_one_call_site_per_outcome`** (the + generalized-intent invariant recorded in plan 06-01's ``). A + source-level test, using `test_pas_plugin.py`'s existing read idiom + (`os.path.dirname(imio.googleauthenticator.__file__)`, then `open`). Read + `browser/forms/token.py`, `browser/forms/user_setup.py` and + `browser/forms/reset_bar_code.py`. Assert: + 1. `token.py`'s source contains exactly one occurrence of the dispatcher call form + `validate_second_factor(` -- exactly one, counted, not merely present. Two occurrences means + someone added a parallel branch, which is precisely the singular-assumption regression this + test exists to catch. + 2. `token.py`'s source contains exactly one `register_failed_second_factor(` call and exactly + one `reset_failed_second_factor(` call, so every refused second factor of every kind routes + through one failure path and every accepted one through one success path. + 3. `user_setup.py`'s and `reset_bar_code.py`'s sources each still contain `validate_token(` -- + a positive control proving the search works and that both still demand a TOTP code. + 4. `user_setup.py`'s and `reset_bar_code.py`'s sources do not contain the dispatcher call form. + Both views exist to prove current possession of the authenticator device; a recovery code + accepted at either would let one code perpetuate itself into a fresh set or a fresh seed + with no device proof. + Docstring must state that assertion 3 is the non-vacuity control for assertion 4, and that the + counted assertions in 1 and 2 are what encode the generalized intent -- one second-factor + concept, one dispatch point, one outcome pair -- so a future phase adding a third credential + kind extends the dispatcher rather than the view. + + Extend this class's `tearDown` mapping if plan 06-01 did not already clear the two new + properties; a set minted by one method must not leak into the next method sharing this layer. + + Commit with `git commit --no-verify`. + + + bin/test -t test_token + + + - `bin/test -t test_token` exits 0 and its output reports all three of `test_recovery_code_failure_shares_the_totp_lockout_counter`, `test_low_recovery_code_count_warning` and `test_second_factor_dispatch_has_exactly_one_call_site_per_outcome` as run. + - Behaviour: five failures made of one wrong recovery code, three wrong six-digit codes and one more wrong recovery code set `two_factor_authentication_locked_until` above `int(time.time())` and `two_factor_authentication_failed_attempts` to `0`; after only four of them the lock epoch is still `0`. + - Behaviour: a genuine unused recovery code submitted after the lock is cleared logs the user in and leaves both the counter and the lock epoch at `0`. + - Behaviour: the consumption that leaves exactly three codes renders a `warning`-class status message containing `Recovery codes remaining:`; the consumption that leaves four renders none. + - Behaviour: a failed submission and an anonymous unsigned submission each render no message containing `Recovery codes remaining:`. + - Behaviour: the source-level method fails if a second `validate_second_factor(` call is added anywhere in `browser/forms/token.py`.

It skips re-rendering the wrapped form only when the response status is 302/303 (a +redirect). The existing `handleSubmit` pattern in this codebase always redirects on success; this +phase's enrollment success path must be the one exception — generate and store the hashes, then +render the ten plaintext codes **in the same response**, by overriding `SetupForm.render()` to +check an instance flag set inside `handleSubmit`, instead of redirecting.

Any write must live in a browser form view. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Slow, salted hashing of the recovery code | A custom loop hashing SHA-256 N times | stdlib `hashlib.pbkdf2_hmac('sha256', ...)` | Correctly implements RFC 8018 PBKDF2 (proper HMAC construction, correct iteration semantics); hand-rolled iterative hashing is a classic source of subtly broken KDFs | +| Constant-time comparison of the submitted code's hash against stored hashes | A manual `==` loop, or Python's `==` on hex strings | stdlib `hmac.compare_digest` (already imported in `helpers.py`) | Timing side-channels on secret comparison are solved; this codebase already uses this exact function for `validate_bar_code_reset_token` | +| Base32 encoding of the 10-byte random code | A hand-written alphabet mapper, or the `rebus` package this phase's brief and stale docs mention | stdlib `base64.b32encode` (already used one function above, in `generate_secret`) | `rebus` is not an actual dependency of this codebase (see Package Legitimacy Audit); the seed-generation code already solved this exact problem with zero extra imports | +| One-time "here are your codes" display | A signed one-time-view URL, a server-side session store, or a transient ZODB record with its own expiry/cleanup | Render inline from the same POST response by overriding the form's `render()` | Verified against the pinned `plone.z3cform` egg: no new storage surface, no expiry logic, nothing for a second request to leak | +| Recovery-code brute-force throttling | A second, parallel counter/lockout mechanism scoped to recovery codes | The exact `register_failed_second_factor` / `is_account_locked` / `reset_failed_second_factor` functions Phase 5 already built | This literally is RECOV-05's success criterion; a second counter is not redundant, it is the exact bug (an unthrottled path) this phase exists to prevent | + +**Key insight:** This phase adds almost no new *mechanism* — it reuses the existing memberdata +storage substrate, the existing single-dispatch-point pattern, the existing lockout counter, and +the existing stdlib imports `helpers.py` already has open. The only genuinely new piece of logic +is the PBKDF2 hash-and-compare, which is one stdlib call plus one existing stdlib comparison. + +## Common Pitfalls + +### Pitfall 1: Forgetting the `memberdata_properties.xml` entries +**What goes wrong:** `two_factor_authentication_recovery_codes_salt` and +`_hashes` are written via `setMemberProperties`, but the write silently does nothing — the codes +appear to generate and validate correctly in a single in-memory test, then vanish on the next +request. +**Why it happens:** `MutablePropertySheet.setProperties` (verified this session by reading +`Products.PlonePAS/sheet.py` from the installed egg) pops any key not present in +`self._properties.keys()` with no error at all — the exact MFA-13 hazard, now for two new +properties. +**How to avoid:** Add both entries to `profiles/default/memberdata_properties.xml` in the same +commit as the helper functions, and write a set/get round-trip test for each, per the MFA-13 +convention this codebase already follows. +**Warning signs:** A test that creates a user, generates codes, and reads them back *within the +same test method* passes, but a second, separately-committing test (or a real browser round +trip) shows an empty property. + +### Pitfall 2: Hashing the display form instead of the canonical form +**What goes wrong:** The stored hash is computed over the code as the user will type it back +(with the display grouping dashes, or in whatever case they paste it), so a validly-typed code +with different-but-equivalent formatting is rejected. +**Why it happens:** Generation and verification must hash the *exact same string*. If generation +hashes the raw ungrouped uppercase code but the display shows a dashed/grouped form, verification +must normalize the submitted input back to the same canonical form before hashing — not the other +way around. +**How to avoid:** `_normalize_recovery_code_input` runs on the submitted value only, before +hashing; the stored hash is always computed over the raw 16-char uppercase string generated by +`generate_recovery_codes`. The dashes are presentation-only and never enter the hash. +**Warning signs:** A code copy-pasted with its display formatting fails on first use, but the +same code retyped without dashes succeeds. + +### Pitfall 3: A per-code salt reintroduced by accident +**What goes wrong:** A future edit "improves" security by giving each code its own salt, silently +turning one PBKDF2 call per login attempt into ten. +**Why it happens:** Per-code salting is the more common textbook pattern for hashed secret lists; +it is *wrong here specifically* because of the shared-salt DoS tradeoff PROJECT.md already +reasoned through. +**How to avoid:** Keep `two_factor_authentication_recovery_codes_salt` singular (one value, not a +list), and validate that any patch touching this area doesn't add a per-hash salt field. +**Warning signs:** A recovery-code login attempt takes noticeably longer than ~0.1-0.25s (this +session's measured range for 20k-200k iterations); ten times that is the DoS symptom, not a +performance fluke. + +### Pitfall 4: Writing recovery-code state from the PAS plugin or the `IPubBeforeCommit` subscriber +**What goes wrong:** A counter or hash-consumption write placed in `pas_plugin.py` or +`subscribers.py` silently never persists on the request path that most needs it (the +`Unauthorized`-ending challenge path aborts its transaction). +**Why it happens:** Exactly the MFA-12 hazard PROJECT.md restates as a standing constraint; +recovery codes are new *writers* of state Phase 5's invariant already covers for existing state. +**How to avoid:** All new writes (`generate_recovery_codes`, the consume-on-match write inside +`validate_recovery_code`) must be reachable only from `browser/forms/token.py` and +`browser/forms/user_setup.py`. Extend +`tests/test_pas_plugin.py::test_no_second_factor_state_written_from_the_plugin`'s +`property_names`/`helper_function_names` tuples with the two new property names and the three new +helper function names — the guard test cannot protect a module it doesn't scan. +**Warning signs:** The extended source-grep test passes trivially without ever having been made +to fail first (no non-vacuity control) — per this codebase's own established pattern (Phase 5's +"reproduced failing" discipline), deliberately introduce one of the forbidden names into +`pas_plugin.py` locally and confirm the test catches it before considering the guard done. + +### Pitfall 5: Blindly adopting OWASP's 600,000-iteration PBKDF2-HMAC-SHA256 figure +**What goes wrong:** Setting iterations to 600,000 "because OWASP says so" costs ~0.7s per +recovery-code login attempt on this hardware (linear extrapolation from the measured 100k/0.117s +figure) for no proportionate security gain. +**Why it happens:** OWASP's Password Storage Cheat Sheet figure (confirmed via WebSearch this +session, see Sources) is calibrated against **GPU-accelerated offline cracking of low-entropy, +human-chosen passwords** — a completely different threat model from an 80-bit CSPRNG-random code +with no dictionary to walk. The roadmap's own phase notes already state this explicitly ("not +load-bearing — the codes are 80-bit random values with no dictionary to walk, so iterations are +insurance"). +**How to avoid:** Use a value in the roadmap's own pre-agreed 20k-200k range. This research +recommends 100,000 (0.117s measured, matches the roadmap's carried-forward figure, comfortably +mid-range). +**Warning signs:** A code review citing OWASP's cheat sheet as grounds to raise the iteration +count past 200,000 for this specific field, without engaging with the entropy-source difference. + +## Code Examples + +### `memberdata_properties.xml` additions + +```xml + + + + +``` + +### `token.py`'s one-line call-site change + +```python +# Source: this codebase, browser/forms/token.py:113 (existing line, for context) +# Before: +valid_token = validate_token(token, user=user) +# After: +valid_token = validate_token_or_recovery_code(token, user=user) +``` + +Nothing else in `token.py`'s `handleSubmit` changes — `reset_failed_second_factor` on success and +`register_failed_second_factor` on failure already wrap this one call site (lines ~118-142), +which is exactly how RECOV-05 is satisfied without new plumbing. + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| No self-service recovery path; only an emailed, signed bar-code reset link (`request_bar_code_reset.py`) | Ten single-use, PBKDF2-hashed recovery codes, issued at enrollment, throttled by the shared lockout counter | This phase | A lost-device user regains access without an admin action and without an unthrottled brute-force path | +| PBKDF2 (any KDF) as the default choice for new secret-hashing systems | Argon2id is OWASP's current top recommendation for *user-chosen, low-entropy* secrets; PBKDF2-HMAC-SHA256 remains the FIPS-140-compliant choice and is explicitly still endorsed where a compliant/simpler KDF is needed | OWASP Password Storage Cheat Sheet, ongoing | Not a reason to switch here: this project's threat model (high-entropy random codes, no PEP-517-requiring new dependency allowed) is exactly the case where PBKDF2 remains the right-sized, lower-footprint choice | + +**Deprecated/outdated:** None specific to this phase's own scope. `.claude/CLAUDE.md`'s +"Key Dependencies" reference to `rebus` for base32 encoding is stale (see Package Legitimacy +Audit) and should not be treated as current. + +## Assumptions Log + +| # | Claim | Section | Risk if Wrong | +|---|-------|---------|---------------| +| A1 | `argon2-cffi`'s current Python 2.7 support / PEP 517 status | Standard Stack, Alternatives Considered | Low — the recommendation to use stdlib PBKDF2 stands regardless, given the "nothing may require PEP 517" hard constraint; this claim only supports *why* Argon2 wasn't seriously evaluated, not the actual choice made | +| A2 | 100,000 PBKDF2 iterations is the "right" final number vs. some other value in the 20k-200k envelope | Standard Stack / Common Pitfall 5 | Low-Medium — the roadmap itself calls this "not load-bearing"; any value the planner or a checkpoint picks in that range is defensible. This research recommends 100,000 with measured timing evidence, but the exact number is properly a planner/operator call, not a research-settled fact | + +**If a checkpoint is warranted:** The iteration-count decision is explicitly called out in +ROADMAP.md as an "Open Decision to settle here" — the planner should surface a +`checkpoint:human-verify` or at minimum record the final chosen value as a decision in STATE.md, +per this phase's own note, rather than silently picking one. + +## Open Questions + +1. **Should recovery codes also be accepted at `@@reset-bar-code`, not only at + `@@google-authenticator-token`?** + - What we know: ROADMAP.md's Phase 6 "Depends on" line names "the single dispatch point in + the token form" specifically (singular), and `reset_bar_code.py` validates the user's + *current* TOTP token as proof of identity before resetting the bar code image, a + conceptually different check than "log in with a second factor." + - What's unclear: Whether an operator would want a lost-recovery-codes-and-lost-device user to + be able to use a recovery code to *also* reset their bar code (recovering both at once), or + whether that's considered out of scope this phase. + - Recommendation: Scope this phase to `token.py` only, per the roadmap's own explicit wording. + `reset_bar_code.py` and `user_setup.py` keep calling `validate_token` directly, unchanged. + If the operator wants recovery-code support there too, it's a small additive follow-up (swap + the same one call site to the same dispatcher), not a redesign. + +2. **Should the "≤3 remain" warning also persist on the personal-information page until the user + regenerates, rather than firing only at the moment of consumption?** + - What we know: RECOV-07's literal text ("warned when 3 or fewer codes remain") is satisfied + by a one-time-per-login `IStatusMessage`, which is the minimal implementation and adds no + new registration surface (no viewlet, no schema field). + - What's unclear: Whether iMio's operators would prefer a persistent visual indicator (e.g., a + small viewlet on `personal-information`) so a user who hasn't needed a recovery code in a + while still sees the count. + - Recommendation: Ship the login-time `IStatusMessage` first (satisfies the literal + requirement with the least new surface); treat a persistent viewlet as an optional + enhancement, not required for RECOV-07 as written. + +## Environment Availability + +Skipped — this phase introduces no new external tool, service, or runtime dependency.

The login form (`browser/forms/token.py`) and the seed-reset form (`browser/forms/reset_bar_code.py`) both do all three. Because the "Regenerate recovery codes" menu item points at this same form, that unmetered check is what stands in front of minting a fresh set of ten codes. The exposure is bounded: the same page renders the account's own authenticator QR code, which contains the secret, to any logged-in site-local user who opens it (`browser/forms/user_setup.py:169`), so repeated guessing gains an attacker nothing they could not read directly off the page. The gap predates this phase — phase 5 added the rate limiting to the seed-reset form and did not extend it here.

No lockout wiring will be added to `browser/forms/user_setup.py` in +Phase 6. Phase 6 closes with this state recorded. + +**Rationale carried forward.** The exposure is bounded by the fact that the same form +already renders the account's own TOTP secret (as a QR code) to any authenticated, +site-local user who loads it, so repeated code guessing gains an attacker nothing they +could not read directly off the page. Closing the gap remains worthwhile for consistency +between the three second-factor checks and is a candidate for a later phase. + +**What the code does today.** `browser/forms/user_setup.py:94` validates the submitted +TOTP code with a bare `validate_token(token)` call. It does not call `is_account_locked` +before the check, does not call `register_failed_second_factor` when the check fails, and +does not call `reset_failed_second_factor` when it succeeds. The two other places in this +package that check a second factor both do all three: `browser/forms/token.py` (the login +gate, lines 108/113/120/140) and `browser/forms/reset_bar_code.py` (the seed-reset gate, +lines 123/132/145/170). + +**Why it matters for this phase.** `profiles/default/actions.xml` adds a +`regenerate_recovery_codes` portal action pointing at `@@setup-two-factor-authentication`, +and its own inline comment names that form's TOTP check as the gate protecting +regeneration. So the one unthrottled second-factor check in the package is now the check +standing in front of minting a fresh, durable set of ten recovery codes. + +**Correction to how the code review and verifier described the risk.** Both reports frame +this as an unlimited six-digit brute-force window. That framing is overstated. The same +form's `updateFields` (user_setup.py:169) renders the account's own QR code — which encodes +the TOTP secret — to any authenticated, site-local user who loads the page. Anyone in a +position to guess the code repeatedly can instead read the secret directly off the rendered +form. The gap is a real inconsistency between the three second-factor gates and is worth +closing for defense in depth and for consistency, but it is not the brute-force hole the +two reports describe. + +**Scope note.** This predates Phase 6 — phase 05-03 added the lockout wiring to +`reset_bar_code.py` and did not extend it to `user_setup.py`. No ROADMAP success criterion +and no plan `must_haves.truth` for Phase 6 requires this endpoint to be rate-limited, so +nothing in the phase mechanically fails because of it. + +## Summary + +total: 1 +passed: 1 +issues: 0 +pending: 0 +skipped: 0 +blocked: 0 + +## Gaps diff --git a/.planning/phases/06-recovery-codes/06-VALIDATION.md b/.planning/phases/06-recovery-codes/06-VALIDATION.md new file mode 100644 index 0000000..5e615b8 --- /dev/null +++ b/.planning/phases/06-recovery-codes/06-VALIDATION.md @@ -0,0 +1,85 @@ +--- +phase: 6 +slug: recovery-codes +# status lifecycle: draft (seeded by plan-phase) → validated (set by validate-phase §6) +# audit-milestone §5.5 distinguishes NOT-VALIDATED (draft) from PARTIAL (validated + nyquist_compliant: false) (#2117) +status: draft +nyquist_compliant: false +wave_0_complete: false +created: 2026-08-03 +--- + +# Phase 6 — Validation Strategy + +> Per-phase validation contract for feedback sampling during execution. + +--- + +## Test Infrastructure + +| Property | Value | +|----------|-------| +| **Framework** | `zope.testrunner` via `bin/test`, unittest2-style test cases on `plone.app.testing` layers | +| **Config file** | None dedicated — discovery comes from the buildout `[test]` part in `base.cfg`; layers live in `src/imio/googleauthenticator/testing.py` | +| **Quick run command** | `bin/test -t test_helpers` (unit) / `bin/test -t test_token` (integration) | +| **Full suite command** | `bin/test -t '!robot'` | +| **Estimated runtime** | ~90 seconds full suite (layer setup dominates); ~20 seconds for a single `-t` selector | + +--- + +## Sampling Rate + +- **After every task commit:** Run `bin/test -t test_helpers` and/or `bin/test -t test_token` — whichever file the task touched +- **After every plan wave:** Run `bin/test -t '!robot'` +- **Before `/gsd-verify-work`:** Full suite must be green +- **Max feedback latency:** 90 seconds + +--- + +## Per-Task Verification Map + +Task IDs are assigned when PLAN.md files are written; `/gsd-validate-phase 6` fills this table +against the real task list.

An account reachable with only a password (pre-enrollment, or after a self-service disable that leaves the seed intact) lets an attacker submit unlimited six-digit guesses at `@@setup-two-factor-authentication` with zero rate limiting — a 1,000,000-value keyspace with no throttling — to both seize the TOTP association and mint a fresh, durable, TOTP-independent set of 10 recovery codes that outlives a later password change. + +This is **not a fresh Phase 6 regression** — the missing lockout wiring in `user_setup.py` predates this phase (05-03 wired `reset_bar_code.py` but never `user_setup.py`) — but Phase 6 materially raises the stakes by making this exact unthrottled check the gate for minting a persistent backdoor credential. No `must_haves.truth` in any of the three 06-0x-PLAN.md files, and no ROADMAP success criterion, explicitly requires this endpoint to be rate-limited, so this does not mechanically FAIL any of the phase's 5 stated success criteria — hence it is not treated as a BLOCKER here. But it is a confirmed, unresolved CRITICAL finding in this phase's own code review (`06-REVIEW.md`, `status: issues_found`), with no follow-up fix commit in the branch (`git log` shows `a6b06ec` — the review commit itself — as HEAD; no subsequent commit touches `user_setup.py`'s lockout wiring). + +**Routed to human verification** rather than either silently passing or unilaterally blocking, since accepting or fixing this is a risk/scope judgment call, not a mechanical check. + +Other 06-REVIEW.md findings (not re-litigated here as blockers, since none are must-haves in the PLAN frontmatter, but worth carrying forward): + +- **WR-01**: an exception inside `generate_recovery_codes` leaves `enable_two_factor_authentication=True` with zero recovery codes stored, while the earlier "successfully enabled" status message has already been queued alongside the later "Setup failed!" message — a contradictory pair shown to the user. Confirmed present in `user_setup.py:106-124` (the success message precedes the mint call inside the same `try`). +- **WR-02**: no GenericSetup upgrade step exists for the two new memberdata properties, so a site upgraded in place (rather than freshly installed) will silently drop both new properties on `setMemberProperties` per this project's own documented "undeclared properties are silently popped" hazard. This repeats the same open gap Phase 5 left for its own three properties. +- **WR-03**: RECOV-03's "shown once" guarantee is asserted only against the raw `SetupForm` instance (`.render()` called directly), never through the actually-registered `SetupFormView = wrap_form(SetupForm)` view a real browser request reaches; a future `plone.z3cform` pin bump could silently break the mechanism with no test failing. + +None of WR-01/02/03 are must-haves in the PLAN frontmatter and none contradict a stated ROADMAP success criterion, so they are recorded here as carried-forward context rather than gaps of this verification. + +### Test Suite + +`bin/test -t '!robot'` run directly by this verifier: **98 tests, 0 failures, 0 errors** (94 integration + 4 unit), matching all three SUMMARY.md claims.

The one open item is CR-01 — an unresolved, confirmed CRITICAL code-review finding that does not mechanically falsify any stated success criterion but represents a genuine security gap in the sole gate protecting RECOV-06's regeneration path, and is routed to human decision rather than silently passed or used to block the phase outright. + +--- + +*Verified: 2026-08-04T08:03:21Z* +*Verifier: Claude (gsd-verifier)* diff --git a/.planning/phases/07-coexistence-with-imio-dms-mail/07-01-PLAN.md b/.planning/phases/07-coexistence-with-imio-dms-mail/07-01-PLAN.md new file mode 100644 index 0000000..d76fe7d --- /dev/null +++ b/.planning/phases/07-coexistence-with-imio-dms-mail/07-01-PLAN.md @@ -0,0 +1,655 @@ +--- +phase: 07-coexistence-with-imio-dms-mail +plan: 01 +type: execute +wave: 1 +depends_on: [] +files_modified: + - src/imio/googleauthenticator/browser/forms/token.py + - src/imio/googleauthenticator/profiles/default/jsregistry.xml + - src/imio/googleauthenticator/browser/static/plone_ecmascript/popupforms.js + - src/imio/googleauthenticator/adapter.py + - src/imio/googleauthenticator/helpers.py + - src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt + - src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt.metadata + - src/imio/googleauthenticator/tests/test_setuphandlers.py + - src/imio/googleauthenticator/tests/test_token.py + - src/imio/googleauthenticator/tests/test_adapter.py +autonomous: true +requirements: [COEX-01, COEX-02, COEX-03, COEX-09, BUG-01, BUG-06] + +must_haves: + truths: + - "A `Browser` that clicks the header \"Log in\" link (never POSTing to `login_form` directly) lands on the token form at `@@google-authenticator-token`, and a valid TOTP submitted there completes the login." + - "The HTML served at `@@google-authenticator-token` contains the literal `id=\"login_form\"` on its `` tag, which is the attribute Plone's own untouched overlay script binds on." + - "This package registers no client-side asset named after a Plone resource: `portal_javascripts` carries `++resource++imio.googleauthenticator/main.js` and Plone's own stock overlay script, and nothing this package installs unregisters or disables the latter." + - "An off-site `next_url` on the token-form URL is refused: the post-token redirect goes to the portal context URL instead.

It is read by z3c.form internals only. +- `plone.z3cform 0.8.1`'s `templates/macros.pt` `titlelessform` macro — used by **both** the + wrapped path (`wrappedform.pt`, which is what `wrap_form()` produces) and the standalone path + (`form.pt`) — emits ``. **No `id` attribute, anywhere in the render chain.** + +So setting `id = 'login_form'` as a class attribute changes a Python property and produces no +`id` attribute in the response body. Do **not** set that class attribute: it would shadow +z3c.form's own property for no benefit and mislead the next reader. The *rendered* attribute is +the only mechanism, and a `render()` override is the smallest way to produce it. Forking the +template would re-introduce exactly the vendoring this phase exists to remove. + +Second correction, affecting Task 2's framing: the ROADMAP says deleting the vendored login form +"restores the field and changes what `ICameFrom` sees". The restored stock hidden input lands in +`request.form`, whereas `CameFromAdapter.getCameFrom()` reads `HTTP_REFERER`'s **query string** +(via `helpers.extract_next_url_from_referer`). The restored input therefore does **not** by itself +change what the adapter sees.

No new +imports. + +Write a reStructuredText docstring on the method carrying the *reason*, in this package's +`:return type:` convention, and say all four of these things: that `plone.z3cform 0.8.1`'s +`titlelessform` macro emits no `id` attribute on the form tag; that Plone's own untouched overlay +script binds its ajax overlay on a `form#login_form` selector; that the form this must match is the +**second**, ajax-loaded fragment, not the stock login form Plone already renders correctly; and +that forking the macro instead would re-vendor the code this phase removes. Someone will try to +delete this method as a hack — the docstring is what stops them. + +**2. Delete the vendored client asset** (requirement COEX-03): remove +`src/imio/googleauthenticator/browser/static/plone_ecmascript/popupforms.js` with `git rm`, and +remove the now-empty `plone_ecmascript/` directory. Leave `browser/static/main.js` and +`browser/static/main.css` and the `browser:resourceDirectory` registration in +`browser/configure.zcml` untouched. + +**3. Edit `profiles/default/jsregistry.xml`** (requirement COEX-03). Delete two entries: the +`` line (this is the global mutation that +unregisters Plone's own resource — it is why the collision with `imio.dms.mail` flips on install +order), and the three-line `` +registration. Keep the `++resource++imio.googleauthenticator/main.js` entry byte-identical, +including its `insert-bottom="True"`. In the long explanatory comment above it, keep every clause +about `main.js` and the fresh-site load-order incident, and remove only the two clauses that +describe the vendored copy's parse-time `jQuery.extend(jQuery.tools.overlay.conf, ...)` call and +its dependency on `plone.app.jquerytools` — after this commit no such file exists, so those +sentences would send the next reader looking for it. Adjust the surrounding wording so the comment +reads as describing one script, not two. + + +**4. Fix `test_registered_javascript_loads_after_jquery`** in `tests/test_setuphandlers.py`. Its +`ours` tuple currently contains two ids; reduce it to the single +`'++resource++imio.googleauthenticator/main.js'` entry. Keep the loop, keep both non-vacuity +`assertIn` controls on `++resource++plone.app.jquery.js` and +`++resource++plone.app.jquerytools.js`, keep the `last_dependency` computation. Delete the +docstring sentence about the vendored copy's parse-time call and leave the `main.js` +`$(document).ready(...)` sentence, so the docstring still explains why the remaining assertion +matters. **Do not touch `test_every_javascript_registration_pins_its_position`** — it parses the +XML and skips removal nodes, so it is already correct after change 3. + +**5. Add `test_popupforms_js_is_not_vendored`** to `TestSetupHandlers` in the same file +(requirement COEX-03). Three assertions, in this order: +(a) a filesystem fact — the vendored asset path under +`os.path.dirname(imio.googleauthenticator.__file__)` does not exist, using the same +`os.path.dirname(imio.googleauthenticator.__file__)` idiom the module's existing `JSREGISTRY_XML` +constant uses; +(b) an XML fact — parse `JSREGISTRY_XML` with the already-imported `minidom` and assert no +`` node's `id` attribute mentions the stock resource name, and that no node carries a +`remove` attribute at all (a positive statement of the invariant: this profile registers, it never +unregisters); +(c) a live-registry fact — `getToolByName(self.portal, 'portal_javascripts')`'s resource ids still +contain the stock overlay resource id, which is the assertion that actually proves the +`imio.dms.mail` collision is closed rather than merely that our file changed. Add a non-vacuity +control asserting the ids list is non-empty. Give the test a docstring naming COEX-03 and stating +that `imio.dms.mail`'s `profiles/default/jsregistry.xml` carries a bare reposition entry for that +same id, which repositions an existing resource and cannot create one. + +**6. Add `test_token_form_carries_login_form_id` and `test_login_link_reaches_token_form`** to the +existing `TestTokenFormLockout` class in `tests/test_token.py`. + +R5-vs-repo note, resolve it this way and record it in the SUMMARY: the plone-write-tests skill's R5 +says one test class per tested class and one test method per tested method. This repo's own WR-03 +precedent (documented in `tests/test_setuphandlers.py`'s and `tests/test_token.py`'s class +docstrings) is one method per *requirement*. R7 says stay consistent with the package — follow +WR-03, add the methods to the **existing** `TestTokenFormLockout` class (which already owns every +fixture these tests need: the Fernet key in `setUp`, the state reset in `tearDown`, `_enable_2fa`, +`_get_browser`, `_login_browser`, `_submit_token`), and add one sentence to that class's docstring +noting it now also covers COEX-01, COEX-09 and BUG-01. Do **not** create a second test class and do +**not** duplicate the fixture. + +`test_token_form_carries_login_form_id`: call `self._enable_2fa()`, get a browser, `_login_browser` +with `TEST_USER_NAME`/`TEST_USER_PASSWORD`, assert the browser is on +`@@google-authenticator-token`, then assert the literal `id="login_form"` is in +`browser.contents`. Docstring must state the pitfall it guards: a test that asserts only HTTP 200 +passes while the overlay silently never binds. + +`test_login_link_reaches_token_form`: the requirement is explicitly that the *link* is the test, not +a direct POST. Sequence: `self._enable_2fa()`; a fresh browser; `browser.open(self.portal_url)`; +locate the header login link — try `browser.getLink('Log in')` first, and if +`zope.testbrowser`/`mechanize` raises an ambiguity error, disambiguate with `index=0` and assert +`browser.url` ends with `/login` so the test still proves it followed the personal-tools action and +not some other link. Then fill `__ac_name`/`__ac_password` and click the submit control on the +rendered form (the same control names `BaseTest._login_browser` uses), assert +`@@google-authenticator-token` is in `browser.url`, assert `id="login_form"` is in +`browser.contents`, then compute a valid code with `get_totp(helpers.get_secret(user), +as_string=True)`, submit it with `self._submit_token`, and assert the browser has left the token URL +— i.e. the login completed. Docstring must state the honest limitation, in these terms: this proves +the markup and the redirect chain, and it cannot prove the jQuery Tools overlay binds, because +`zope.testbrowser` has no JavaScript engine; the JS-level proof is the human-verify item in plan +07-04, and a verification report claiming COEX-09 is fully automated is wrong. + + + + bin/test -t test_token_form_carries_login_form_id + bin/test -t test_login_link_reaches_token_form + bin/test -t test_popupforms_js_is_not_vendored + bin/test -t test_registered_javascript_loads_after_jquery + bin/test -t test_every_javascript_registration_pins_its_position + + + +- `bin/test -t test_token_form_carries_login_form_id` exits 0. +- `bin/test -t test_login_link_reaches_token_form` exits 0. +- `bin/test -t test_popupforms_js_is_not_vendored` exits 0. +- `bin/test -t test_registered_javascript_loads_after_jquery` exits 0 and + `bin/test -t test_every_javascript_registration_pins_its_position` exits 0 — both pre-existing + tests, neither newly skipped. +- `bin/test -t '!robot'` exits 0 (whole suite green). +- `grep -q 'def render(self):' src/imio/googleauthenticator/browser/forms/token.py` succeeds. +- `grep -q 'id="login_form"' src/imio/googleauthenticator/browser/forms/token.py` succeeds. +- `grep -c 'id = .login_form.' src/imio/googleauthenticator/browser/forms/token.py` returns 0 — + the inert class attribute the ROADMAP's wording implies must NOT be set. +- `test ! -e src/imio/googleauthenticator/browser/static/plone_ecmascript` succeeds. +- `! grep -q 'popupforms' src/imio/googleauthenticator/profiles/default/jsregistry.xml` succeeds. +- `grep -c 'remove=' src/imio/googleauthenticator/profiles/default/jsregistry.xml` returns 0. +- `grep -q 'insert-bottom="True"' src/imio/googleauthenticator/profiles/default/jsregistry.xml` + succeeds — `main.js` keeps its pinned position. +- Non-vacuity mutation check, run and recorded in the SUMMARY: with the `render()` override + reverted locally, `bin/test -t test_token_form_carries_login_form_id` goes red; restore the + method byte-identical afterwards. +- Exactly one commit for this task, and its diff touches exactly the five paths in ``. + + + Deleting the vendored asset, its two registry entries and the + `render()` override are all restorable by `git revert`; nothing persisted in the ZODB depends on + them (see the operational note in plan 07-04 for the one dev site that already carries the stale + mutation). + + +Clicking the header "Log in" link as a 2FA-enabled user reaches the token form and a valid code +completes the login; the token form's markup carries `id="login_form"`; no vendored client asset +and no registry-removal entry remain; both pre-existing jsregistry tests are green, unskipped. + + + + + Task 2: Delete the vendored login-form override and close both ends of the next_url pipe — one commit + + +src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt (DELETE) +src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt.metadata (DELETE) +src/imio/googleauthenticator/browser/forms/token.py +src/imio/googleauthenticator/adapter.py +src/imio/googleauthenticator/helpers.py +src/imio/googleauthenticator/tests/test_token.py +src/imio/googleauthenticator/tests/test_adapter.py +src/imio/googleauthenticator/tests/test_setuphandlers.py + + + +- `src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt` — being deleted. +- `src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt.metadata` — being + deleted.

ROADMAP success criterion 4 mandates that the redirect validation and the query-string +encoding land in the **same commit** as the login-form override's deletion, because that is the +commit where the whole redirect surface changes; do not split them. + +**1. Delete the override** (requirement COEX-02): `git rm` both +`skins/googleauthenticator_custom/login_form.cpt` and its `.metadata`. Leave the other two files in +that directory alone — `control_panel_extra.html` and `request_bar_code_reset_email.pt` are **live +templates, not overrides**, and plan 07-02 owns converting them. Leave `profiles/default/skins.xml` +and `configure.zcml` alone too; the layer must stay registered until 07-02, or the two live +templates become untraversable. + +**2. BUG-01 — validate the redirect target.** In `token.py`'s `handleSubmit` success branch, after +`redirect_url = request_data.get('next_url', context_url)` and before +`self.request.response.redirect(redirect_url)`, fetch the `portal_url` tool with +`getToolByName(self.context, 'portal_url')` and, when `isURLInPortal(redirect_url)` is falsy, +reassign `redirect_url = context_url`. **Refuse and fall back — do not warn and continue, and do +not rewrite or prefix the attacker's value.** Add the `getToolByName` import copied verbatim from +`request_bar_code_reset.py:16`, placed so isort's `force_single_line` / +`force_alphabetical_sort` ordering in `token.py`'s existing `Products.*` import block still holds. +Add a short comment naming the requirement and pointing at Plone's own stock login form, which uses +this identical `isURLInPortal` idiom for the identical `came_from`/`next` problem — that is the +"don't hand-roll" justification, and it is why no `urlparse` host comparison belongs here. + +**3. BUG-06 — quote on the way in.** In `adapter.py`, `CameFromAdapter.getCameFrom()` currently +calls `extract_next_url_from_referer(self.request)`. Pass `quote_url=True`. That parameter has +existed since before this phase and has never been passed as true anywhere. Nothing else changes in +either file. Extend the method's docstring with one sentence saying the value is quoted because the +consumer appends it to a query string as `&next_url=...` and the reader `unquote()`s it, so an +unquoted `&` or `=` in a `came_from` would split into a forged extra parameter. + +**4. Two stale prose corrections, same commit.** `adapter.py`'s `CameFromAdapter` class docstring +opens by claiming Plone's `came_from` field "had to be taken out of the login form" — after change 1 +that is false; rewrite it to say the value is recovered from the referer's query string and that +this is deliberately independent of whatever hidden inputs the login form renders. Do the same for +the first sentence of `helpers.extract_next_url_from_referer`'s docstring, which makes the same +now-false claim. **State explicitly in the rewritten text that this function reads the referer's +query string and not `request.form`** — that distinction is the second ROADMAP correction at the +top of this plan, and leaving it implicit is what would let a future reader "simplify" the adapter +into reading the restored hidden input and silently change behaviour. + +**5. `test_next_url_is_validated_against_the_portal`** in the existing `TestTokenFormLockout` class +(requirement BUG-01). Both halves in one method, per WR-03. Drive it through a real browser like the +sibling tests: `_enable_2fa`, `_login_browser`, confirm the browser is on the token URL, then +`browser.open(browser.url + '&next_url=http://evil.example.com/')`, submit a valid code with +`_submit_token`, and assert the resulting URL is under `self.portal_url` and does not contain +`evil.example.com`. Then repeat with an on-site `next_url` (the portal URL itself is sufficient) and +assert that one **is** honoured — that second half is the non-vacuity control, without which a +guard that refuses everything would pass. Docstring names BUG-01 and states that the refusal is a +fallback to a known-good same-site URL, not a warn-and-continue. + +**6. New `TestCameFromAdapter` class in `tests/test_adapter.py`** with the single method +`test_get_came_from_quotes_the_value` (requirement BUG-06). Copy the layer wiring and `setUp` shape +from `TestEnhancedUserDataPanelAdapter` in the same file. All imports at module level (R6) — the +class needs `CameFromAdapter` and the reader helper from `helpers`. Cover four scenarios in the one +method, per R5/WR-03: +(a) round-trip integrity — set `HTTP_REFERER` on the request to a portal URL whose query string +carries a `came_from` value containing a `+`, a space, an `&`, an `=` and a percent-encoded UTF-8 +character; assert `getCameFrom()`'s output, fed back through +`helpers.extract_request_data_from_query_string('came_from=' + result)`, yields the original value +byte-for-byte; +(b) type — assert the returned value is a `str`, not a `unicode`. State the reason in the docstring: +Python 2's `urllib.quote` raises `KeyError` on a non-ASCII `unicode` argument, so if a future change +ever makes the referer path yield unicode, this assertion is what fails instead of a live login; +(c) no referer — with `HTTP_REFERER` absent, assert `''` exactly (not `None`, not `'None'`), because +`send_2fa_redirect` guards its append on truthiness and a `'None'` string would be appended and then +refused by BUG-01's guard, silently losing a legitimate destination; +(d) referer with a query string but no `came_from` key — assert `''`. + +Set the referer by writing to the request the same way the sibling browser-free tests in this suite +manipulate `self.layer['request']`; read the file first and follow whatever it already does rather +than inventing a new mechanism. + +**7. `test_login_form_override_is_deleted`** in `TestSetupHandlers` (requirement COEX-02). A +filesystem fact, using the same `os.path.dirname(imio.googleauthenticator.__file__)` idiom as this +module's `JSREGISTRY_XML` constant: assert neither the override nor its metadata file exists. +Include a positive non-vacuity control in the same method asserting that a file which *should* +still exist under the package directory does exist (pick one that is not scheduled for deletion in +this phase, e.g. `profiles/default/jsregistry.xml`), so a wrong `package_dir` cannot make the +absence assertions pass vacuously. That control is the same trap +`test_no_second_factor_state_written_from_the_plugin` guards against with its per-file positive +controls. + + + + bin/test -t test_next_url_is_validated_against_the_portal + bin/test -t test_get_came_from_quotes_the_value + bin/test -t test_login_form_override_is_deleted + bin/test -t '!robot' + + + +- `bin/test -t test_next_url_is_validated_against_the_portal` exits 0. +- `bin/test -t test_get_came_from_quotes_the_value` exits 0. +- `bin/test -t test_login_form_override_is_deleted` exits 0. +- `bin/test -t '!robot'` exits 0 — in particular `test_login_link_reaches_token_form` from Task 1 + and every existing `tests/test_challenge.py` and `tests/test_pas_plugin.py` test stay green with + the override gone. +- `test ! -e src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt` succeeds. +- `test ! -e src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt.metadata` + succeeds. +- `test -e src/imio/googleauthenticator/skins/googleauthenticator_custom/control_panel_extra.html` + succeeds — the two live templates are still present; 07-02 owns them. +- `grep -q "isURLInPortal" src/imio/googleauthenticator/browser/forms/token.py` succeeds. +- `grep -q "quote_url=True" src/imio/googleauthenticator/adapter.py` succeeds. +- `git diff --stat HEAD~1 -- src/imio/googleauthenticator/helpers.py` shows only docstring lines + changed — no logic change in `helpers.py`. +- Non-vacuity mutation checks, both run and recorded in the SUMMARY: reverting the `isURLInPortal` + guard turns `test_next_url_is_validated_against_the_portal` red; reverting `quote_url=True` turns + `test_get_came_from_quotes_the_value` red. Restore both byte-identical afterwards. +- Exactly one commit for this task. + + + Both one-line fixes and the two file deletions revert cleanly; + the metadata file was byte-identical to stock, so its deletion has no behavioural delta at + all. + + +The vendored login-form override and its metadata are gone; an off-site `next_url` is refused with a +same-site fallback and an on-site one is honoured; `came_from` is percent-encoded on write and +round-trips through the reader's decode; the two docstrings that claimed the override existed no +longer say so; the whole suite is green. + + + + + + +**Signal:** the assumption-delta detector fired with two `pluralization` signals ("alongside" in +the phase goal, "also" in a phase note). + +**The noun whose ownership changes:** Plone's `popupforms.js` entry in `portal_javascripts`. Today +this package treats it as *ours to delete* (`remove="True"` in `profiles/default/jsregistry.xml`) — +a singular-owner assumption. This phase introduces a second registrant (`imio.dms.mail`, whose own +`profiles/default/jsregistry.xml` carries a bare `insert-after` reposition entry for the same id) +which needs Plone's copy to still exist. The resource is therefore **Plone-owned and shared by +multiple registrants**, not ours. + +**Decision: `promote`.** The general representation becomes primary — *"`portal_javascripts` and +`portal_css` resources are owned by whoever registered them; this package registers, repositions +and unregisters only ids under its own `++resource++imio.googleauthenticator/` prefix."* The old +specific assumption ("this one Plone resource is ours to remove") is demoted to a detail of a +now-deleted variant. Adding the new behaviour alongside the old — keeping `remove="True"` and +merely documenting the hazard — would silently contradict the generalised intent, and is the exact +state this phase exists to end. + +**Reversibility: `reversible`.** Reinstating the singular-owner assumption is one line of XML. + +**Proposed invariant test (not required, but cheap and planned):** +`test_profile_only_registers_resources_it_owns`, added in plan 07-03 Task 1 — parse +`profiles/default/jsregistry.xml`, `profiles/default/cssregistry.xml`, +`profiles/uninstall/jsregistry.xml` and `profiles/uninstall/cssregistry.xml`, and assert every +`id` attribute in all four begins with `++resource++imio.googleauthenticator/`. It goes red the day +any future phase reintroduces a bare Plone resource id in any of this package's registry profiles, +whether to add, move or remove it. + + + +The deterministic edge probe returned 15 applicable rows. Eight came back `unclassified` ("review +manually") and are **surfaced here as explicit flagged assumptions rather than silently +dismissed** — the fallback protocol forbids auto-backstopping an unclassified row. Six of the seven +classified rows are authored as plain-string truths in the `must_haves` of this plan or of 07-03; +one (COEX-03 / concurrency) is authored as a structured `backstop` marker in 07-03. Accounting: +15 in = 6 covered truths + 1 backstop truth + 8 flagged assumptions. + +Rows flagged unclassified, with the planner's reading of what each would have to mean here: + +1. **COEX-01** — no probe category applies cleanly. The substantive risk is not an edge case but the + ROADMAP-vs-source contradiction corrected at the top of this plan; the truth asserting the + literal `id="login_form"` in the served body is what covers it. +2. **COEX-02** — a pure filesystem deletion; no input domain to probe. +3. **COEX-04** — owned by plan 07-02. The real hazard (two live templates hiding in a directory that + looks deletable) is a same-commit ordering constraint, not an edge case. +4. **COEX-05** — same as COEX-02: a deletion fact. +5. **COEX-06** — the closest applicable probe would be idempotency (applying the uninstall profile + twice). 07-03's truths assert it explicitly, grounded in the fact that + `BaseRegistry.unregisterResource` is a filter over the resource tuple and so never raises on a + missing id. +6. **COEX-07** — the adjacency and idempotency rows on COEX-03 carry this requirement's real edge + content; both are authored as truths in 07-03. +7. **COEX-09** — the honest gap is not an edge case but a tooling limit: `bin/test` has no + JavaScript engine. Recorded as the human-verify item in 07-04, never as an automated pass. +8. **BUG-01** — the probe returned no category; the two-sided truth in this plan (off-site refused, + on-site honoured) is the coverage. + +None of the eight is dismissed. Each is either covered by a truth elsewhere or explicitly recorded +as unprobeable-for-this-phase above; a verifier that cannot confirm one of them must abstain to +`human_needed`, not pass it. + + + +## Trust Boundaries + +| Boundary | Description | +|----------|-------------| +| anonymous browser -> `@@google-authenticator-token` query string | attacker-controllable `next_url`, `auth_user`, `ajax_load`; only `auth_user` and `valid_until` are inside the `ska` signature | +| `HTTP_REFERER` header -> `CameFromAdapter.getCameFrom()` -> the signed redirect URL's query string | an attacker who can set a victim's referer controls a value this package concatenates into a URL | +| GenericSetup profile import -> `portal_javascripts` (ZODB) | a profile import mutates site-wide state shared with every other installed add-on | + +## STRIDE Threat Register + +Enforcement level: **OWASP ASVS level 1**; blocking severity threshold: **high**.

This package now registers only its own `++resource++imio.googleauthenticator/main.js`, closing the install-order collision with `imio.dms.mail`'s bare reposition entry for the same stock resource id. +- Deleted the vendored `skins/googleauthenticator_custom/login_form.cpt` override and its byte-identical-to-stock `.metadata` file, restoring Plone's own stock login form (three-hunk delta, confirmed below). +- BUG-01: `token.py`'s `handleSubmit` now validates the post-token redirect target with `portal_url_tool.isURLInPortal()` before redirecting -- an off-site `next_url` is refused and falls back to the portal context URL, never a warn-and-continue, never a rewrite. +- BUG-06: `CameFromAdapter.getCameFrom()` now passes `quote_url=True` to `extract_next_url_from_referer`, so a `came_from` containing `&`, `=`, `+` or a space can no longer forge or truncate the `&next_url=...` parameter `pas_plugin.send_2fa_redirect` appends it to. +- Two stale docstrings (in `adapter.py` and `helpers.py`) that claimed Plone's `came_from` field "had to be taken out of the login form" were corrected to say the value is read from the referer's query string, independently of whatever hidden inputs the login form itself renders. + +## Task Commits + +1. **Task 1: End-to-end "log in through the header link and land on a bindable token form"** - `df39c1d` (feat) +2. **Task 2: Delete the vendored login-form override and close both ends of the next_url pipe** - `6c14064` (feat) + +**Plan metadata:** pending (this commit) + +## Files Created/Modified + +- `src/imio/googleauthenticator/browser/forms/token.py` - added `render()` (COEX-01) and the `isURLInPortal` redirect guard (BUG-01) +- `src/imio/googleauthenticator/profiles/default/jsregistry.xml` - removed the two vendored-asset entries; `main.js` unchanged +- `src/imio/googleauthenticator/browser/static/plone_ecmascript/popupforms.js` - deleted (COEX-03), directory removed with it +- `src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt` - deleted (COEX-02) +- `src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt.metadata` - deleted (COEX-02) +- `src/imio/googleauthenticator/adapter.py` - `quote_url=True` (BUG-06) + docstring correction +- `src/imio/googleauthenticator/helpers.py` - docstring correction only, no logic change +- `src/imio/googleauthenticator/tests/test_setuphandlers.py` - fixed `test_registered_javascript_loads_after_jquery`; added `test_popupforms_js_is_not_vendored`, `test_login_form_override_is_deleted` +- `src/imio/googleauthenticator/tests/test_token.py` - added `test_token_form_carries_login_form_id`, `test_login_link_reaches_token_form`, `test_next_url_is_validated_against_the_portal` +- `src/imio/googleauthenticator/tests/test_adapter.py` - added `TestCameFromAdapter` class with `test_get_came_from_quotes_the_value` + +## Decisions Made + +- **R5-vs-WR-03 test placement** (recorded per the plan's explicit instruction): the plone-write-tests skill's R5 (one test class per tested class, one method per tested method) was overridden in favor of this repo's own WR-03 precedent (one method per *requirement*, grouped by concern). The three new `TokenForm`-facing tests landed in the existing `TestTokenFormLockout` class rather than a new class, reusing its `_enable_2fa`/`_get_browser`/`_login_browser`/`_submit_token` fixtures and the Fernet-key `setUp`/`tearDown` pair. +- **TOTP-interval hazard in the BUG-01 test, found during execution, not called out in the plan**: `test_next_url_is_validated_against_the_portal` needs two *successful* logins in one method (off-site refused, on-site honoured). Two genuine TOTP logins moments apart land in the same or an adjacent ~30-second interval, and `validate_token`'s MFA-06 replay guard refuses a second acceptance of an already-accepted interval. Worked around by using a recovery code (`helpers.generate_recovery_codes`) for the second login instead of a second TOTP code -- recovery codes are not subject to the per-interval guard, and this matches the established precedent in `test_recovery_code_is_accepted_in_place_of_a_token_and_consumed` of alternating credential kinds across sequential logins in one test. +- Confirmed the vendored `login_form.cpt` diff against the stock `Products.CMFPlone` copy is exactly the three hunks the plan's read_first step described (dropping `plone context/@@plone`/`nav_root plone/navigationRootUrl`, building `mail_password` from `portal_url` instead of `nav_root`, and removing the hidden `came_from` input) -- no discrepancy found. +- `browser.getLink('Log in', index=0)` reached the header action with no ambiguity error in either direction; the try/except fallback the plan sketched for a possible `zope.testbrowser`/`mechanize` ambiguity exception was never needed, since `index=0` disambiguates deterministically without raising. + +## Deviations from Plan + +None - plan executed exactly as written. The TOTP-interval workaround above is a test-fixture choice within the plan's own instructions (the plan named the two behaviors to assert but not the mechanism for making both logins succeed independently), not a deviation from any `` instruction, ``, or file scope. + +## Non-Vacuity Mutation Checks (per this repo's established standard) + +All four required mutation checks were run, reproduced red, and restored byte-identical: + +1. **Task 1 - `render()` override reverted to a bare `super().render()` call:** `test_token_form_carries_login_form_id` went red -- the rendered form tag carried `id="form"` (z3c.form's own default), not `id="login_form"`. Restored byte-identical; re-ran green. +2. **Task 2 - `isURLInPortal` guard removed:** `test_next_url_is_validated_against_the_portal` went red with a live `NotFound: no default view (root default view was probably deleted)` error, because the redirect actually reached `http://evil.example.com/` inside the test's fake-host publishing environment -- direct proof the guard's absence is the vulnerability, not merely a missing assertion. Restored byte-identical; re-ran green. +3. **Task 2 - `quote_url=True` reverted to the bare call:** `test_get_came_from_quotes_the_value` went red with `AssertionError: 'plus+space &equals=\xc3\xa9' != 'plus+space '` -- the round-tripped value was truncated at the unquoted `&`, exactly the injection BUG-06 closes. Restored byte-identical; re-ran green. + +(The acceptance criteria list a fourth non-vacuity check under Task 1's bullet list that duplicates check #1 above -- both text passages describe the same `render()` mutation;

this plan's `assumption_delta_decision` (promote: this package registers/repositions/unregisters only ids under its own `++resource++imio.googleauthenticator/` prefix) is now true in the default profile, and 07-03's planned `test_profile_only_registers_resources_it_owns` invariant test has no known counter-example left to find in `profiles/default/`. +- Plan 07-04's human-verify item (the jQuery Tools overlay actually binding and ajax-loading the token form fragment in a real browser) is unblocked and ready -- this plan's automated tests prove the markup and redirect chain but explicitly cannot prove the JS-level bind, per COEX-09's documented honest limitation. +- No blockers. + +## Self-Check: PASSED + +- FOUND: `src/imio/googleauthenticator/browser/forms/token.py` +- FOUND: `src/imio/googleauthenticator/browser/static/plone_ecmascript/` deleted +- FOUND: `src/imio/googleauthenticator/skins/googleauthenticator_custom/login_form.cpt` deleted +- FOUND: `src/imio/googleauthenticator/tests/test_adapter.py` +- FOUND: commit `df39c1d` +- FOUND: commit `6c14064` + +--- +*Phase: 07-coexistence-with-imio-dms-mail* +*Completed: 2026-08-04* diff --git a/.planning/phases/07-coexistence-with-imio-dms-mail/07-02-PLAN.md b/.planning/phases/07-coexistence-with-imio-dms-mail/07-02-PLAN.md new file mode 100644 index 0000000..9e2fc2b --- /dev/null +++ b/.planning/phases/07-coexistence-with-imio-dms-mail/07-02-PLAN.md @@ -0,0 +1,500 @@ +--- +phase: 07-coexistence-with-imio-dms-mail +plan: 02 +type: execute +wave: 2 +depends_on: ["07-01"] +files_modified: + - src/imio/googleauthenticator/browser/controlpanel.py + - src/imio/googleauthenticator/browser/templates/control_panel_extra.pt + - src/imio/googleauthenticator/browser/forms/request_bar_code_reset.py + - src/imio/googleauthenticator/browser/forms/templates/request_bar_code_reset_email.pt + - src/imio/googleauthenticator/skins/googleauthenticator_custom/control_panel_extra.html + - src/imio/googleauthenticator/skins/googleauthenticator_custom/request_bar_code_reset_email.pt + - src/imio/googleauthenticator/profiles/default/skins.xml + - src/imio/googleauthenticator/configure.zcml + - MANIFEST.in + - src/imio/googleauthenticator/tests/test_generic.py + - src/imio/googleauthenticator/tests/test_request_bar_code_reset.py + - src/imio/googleauthenticator/tests/test_controlpanel.py + - src/imio/googleauthenticator/tests/test_setuphandlers.py +autonomous: true +requirements: [COEX-04, COEX-05] + +must_haves: + truths: + - "The Google Authenticator control panel at `@@google-authenticator-settings` still renders the \"Enable two-step verification for all users\" and \"Disable two-step verification for all users\" links, both pointing at the existing helper views, after the skin directory is gone." + - "A bar-code reset request still produces a delivered email whose body contains the site's sender address and the signed reset URL, after the skin directory is gone." + - "No Python file under `src/imio/googleauthenticator/browser/` performs a skin-name traversal any more;

Relocate `control_panel_extra.html`** to +`src/imio/googleauthenticator/browser/templates/control_panel_extra.pt`. Use `git mv` so the move is +visible as a rename in the diff. Standardise on the `.pt` extension (the only other template-shaped +file in `browser/` already uses it; `ViewPageTemplateFile` does not care). **Do not edit the body.** + +**2. Relocate `request_bar_code_reset_email.pt`** to +`src/imio/googleauthenticator/browser/forms/templates/request_bar_code_reset_email.pt`, again with +`git mv` and with no body edit. + +**3. `browser/controlpanel.py`** (requirement COEX-04). Add +`from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile` to the import block, +positioned so isort's `force_single_line` / `force_alphabetical_sort` ordering holds against the +existing `Products.statusmessages...` line. On `GoogleAuthenticatorSettingsEditForm`, declare a +class attribute `additional_template = ViewPageTemplateFile('templates/control_panel_extra.pt')`, +placed with the other class-level declarations (`control_panel_view`, `schema_prefix`, `schema`, +`label`, `description`, `enable_unload_protection`) and not inside a method — the descriptor's +`__get__` is what binds it to the instance. In `render()`, delete the skin-name lookup line and call +`self.additional_template(...)` with the same five keyword arguments and the same values as today +(`enable_url`, `enable_text`, `disable_url`, `disable_text`, `charset`). Keep `return res + +additional`. Everything else in the method is unchanged. + +**4. `browser/forms/request_bar_code_reset.py`** (requirement COEX-04). Same import addition, sorted +against the existing `from Products.CMFCore.utils import getToolByName` line. Declare +`mail_text_template = ViewPageTemplateFile('templates/request_bar_code_reset_email.pt')` as a class +attribute on `RequestBarCodeResetForm`, alongside `fields`, `ignoreContext`, `schema`, `label`, +`description`. In `handleSubmit`, delete the skin-name lookup line and call +`self.mail_text_template(...)` with the same three keyword arguments (`member`, +`bar_code_reset_url`, `charset`). **Keep the following `mail_text.format(bar_code_reset_url=...)` +line exactly as it is** — the template body carries a literal `{bar_code_reset_url}` placeholder +that the Python side substitutes, and dropping the `format` call would ship the literal braces into +a user's mailbox. Keep the whole `try`/`except` structure, the `charset='utf-8'` argument to +`host.send`, and its long explanatory comment untouched. + +**5. Delete the skin mechanism** (requirement COEX-05): `git rm -r` the whole +`src/imio/googleauthenticator/skins/` tree; `git rm` +`src/imio/googleauthenticator/profiles/default/skins.xml`; delete the `cmf:registerDirectory` +element from `configure.zcml` **and** the now-unused `xmlns:cmf` declaration on its root element; +delete the `recursive-include` line in `MANIFEST.in` that names the deleted directory. Do not touch +`profiles/uninstall/skins.xml` — plan 07-03 owns it. + + +**6. Two mandatory pre-existing-test edits, same commit.** In `tests/test_generic.py`, remove the +deleted directive's string from `test_manifest_ships_the_profile_and_catalogues`'s `required` tuple +and leave the other six entries, both `global-exclude` lines included, exactly as they are. In +`tests/test_request_bar_code_reset.py`'s `setUp`, delete the skin-binding call and the two comment +lines above it that explain why it was needed; keep the `self._install()` call and the +`bar_code_reset_token` reset with its comment. These two edits are not optional cleanups — without +them the suite is red at this commit. + +**7. New `tests/test_controlpanel.py`.** Per R5 this is the correct home for a test of +`browser/controlpanel.py`, and no such file exists yet. One class, +`TestGoogleAuthenticatorSettingsEditForm`, on `IMIO_GOOGLEAUTHENTICATOR_INTEGRATION_TESTING` with +`BaseTest`, following the `setUp` shape used by the sibling test modules (`self.app`, +`self.portal`, `self.request`, `self.portal_url`, `self._install()`). All imports at module level +(R6). One method, `test_render_appends_the_extra_links`, covering every scenario in the one method +per R5/WR-03: +- `setRoles(self.portal, TEST_USER_ID, ['Manager'])` first — the control panel requires + `cmf.ManagePortal`, exactly as `test_bulk_enable_reports_failure_when_seed_key_is_broken` does. +- instantiate the form with `(self.portal, self.request)`, call `update()`, then `render()`. +- assert the rendered string contains the enable-for-all-users URL, the disable-for-all-users URL, + and both link texts.

Documented rather than re-split via a follow-up commit, since re-splitting after the fact would require an amend or a revert-and-reapply, neither of which improves the historical record. +- **`git mv` leaves an empty directory:** relocating both templates out of `skins/googleauthenticator_custom/` with `git mv` emptied the directory in git's index but left it physically present on disk (git does not track or remove empty directories). `test_skin_layer_is_removed`'s `os.path.exists(skins_dir)` assertion caught this immediately (it went red on first run) because `os.path.exists()` returns `True` for an empty directory.

R6 applies — module +level, not inside a method. + +**5. Add `test_uninstall_restores_resource_registries` to `TestSetupHandlers`** (requirement +COEX-06). One method, per WR-03, in this order: +(a) precondition/non-vacuity — assert both of this package's resource ids **are** present in +`portal_javascripts` / `portal_css` before the uninstall, or the removal assertions below prove +nothing; +(b) `applyProfile(self.portal, 'imio.googleauthenticator:uninstall')`, then assert both ids are gone; +(c) the coexistence half, and the assertion that actually matters — assert the stock overlay resource +id is **still** in `portal_javascripts` after the uninstall. This is the criterion-3 requirement in +one line: uninstalling this add-on must not leave the whole site without Plone's overlay script; +(d) idempotency — apply the uninstall profile a second time and assert it neither raises nor changes +the resource-id sets. Ground the docstring in the read: `BaseRegistry.unregisterResource` filters the +resource tuple, so a missing id is a no-op rather than a `KeyError`; +(e) reversibility — re-apply the default profile and assert both of this package's ids are back, so +an uninstall followed by a reinstall is a working site rather than a half-registered one. + +Because this test mutates registry state that other methods in this layer read, restore the +installed state at the end of the method (the re-apply in (e) does that as a side effect — say so +explicitly in a comment, and if the layer still leaks, add the same kind of `tearDown` reset the +sibling test modules use rather than reordering the assertions). + +**6. Add `test_popupforms_js_survives_either_install_order` to `TestSetupHandlers`** (requirements +COEX-07, COEX-03). This is a *synthetic* collision test; the real two-egg proof is plan 07-04's +human-verify item, and the docstring must say so in exactly those terms — a verification report +claiming COEX-07 is fully automated is wrong. + +Structure: a small local helper (a method on the class, per R4, since only this test uses it) that +replays `imio.dms.mail`'s reposition against `portal_javascripts` using the tool's own +`moveResourceAfter` with the two ids from the real XML fragment.

Assert the count explicitly with +`list.count(...)`, not merely `assertIn`, because `assertIn` cannot distinguish 1 from 2; +(e) the idempotency edge the probe raised — apply the default profile a **second** time and assert +both the stock overlay id and this package's `main.js` id still appear exactly once.

If the site's `Data.fs` predates this phase, first clear the two stale artifacts named in + `07-03-SUMMARY.md`: re-run `Products.CMFPlone`'s `jsregistry` import step from + `portal_setup` (ZMI -> `portal_setup` -> Import tab -> select the CMFPlone profile -> + run the `jsregistry` step), and remove the leftover `googleauthenticator_custom` object and skin-path + layer from `portal_skins`. Alternatively use a freshly created site, which is cleaner. Say which + route you took. +3. **Order A.** On a clean site, install `imio.dms.mail` first, then `imio.googleauthenticator`. + Then check all three of: + - ZMI -> `portal_javascripts`: Plone's overlay-script resource appears **exactly once**, and is + enabled. + - a `prepOverlay` widget belonging to `imio.dms.mail` still opens as an overlay rather than a full + page — a delete or rename dialog on a content item is the quickest one to reach. + - the 2FA login flow still works end to end for a 2FA-enabled user. +4. **Order B.** Reset to a clean site. Install `imio.googleauthenticator` first, then + `imio.dms.mail`. Repeat all three checks from step 3. +5.

The automated test asserts +that literal appears in the served body and that clicking the header link reaches the token form and +a valid code completes the login. + +What no test in this suite can do is execute the JavaScript. `zope.testbrowser`/`mechanize` has no JS +engine, and `test_robot.py` is excluded everywhere per `CLAUDE.md`. So the automated half proves the +markup and the redirect chain; whether jQuery Tools actually binds the selector, and whether the +`common_content_filter` descendant search reaches the wrapped z3c.form inside `#content`, is only +observable in a real browser. + + + +1. `bin/instance fg`. Log in as a Manager, install the add-on if the site does not have it, and enrol + a test user in two-step verification. +2. Log out. As an anonymous visitor on a normal content page, click the header **"Log in"** link in + the personal-tools bar. **Do not** navigate to `login_form` directly and do not POST to it — the + link is the test, because a direct POST never asks the overlay's form selector to find anything and + would pass while the real UI is dead. +3. Confirm the login form appears **inside an overlay** (a modal panel over the page), not as a full + page navigation. +4. Enter the enrolled user's credentials and submit **inside the overlay**. +5. Confirm the two-step verification form appears **inside that same overlay** — this is the second, + ajax-loaded fragment, and it is the thing the `render()` override exists for. If it renders as a + full page instead, the binding failed and this check is red even though the automated test passed. +6. Enter a valid code from the authenticator app and confirm the login completes and you land on a + logged-in page. +7. Separately, confirm a **warning-level** portal message still renders inside an overlay somewhere on + the site. This is a specific regression the vendored script caused: its content filter omitted the + warning selector, so warning messages were swallowed in every overlay site-wide. The + low-recovery-codes warning added in Phase 6 is a convenient one to trigger, or any other + warning-level `IStatusMessage` shown in an overlay-loaded form. +8.

this research does not present alternatives to them, only how to implement them correctly given what the installed code and eggs actually do (several of which differ from what the roadmap assumed — see `` inline below). + +## Summary + +This phase deletes ~350 lines of vendored Plone core code (`login_form.cpt`, `popupforms.js`, the `skins/` filesystem-directory override, and the `jsregistry.xml` `remove="True"` mutation) and replaces the login-overlay dependency with one small, targeted change to `TokenForm`. The vendored copies are not neutral dead weight: the vendored `popupforms.js`'s login-overlay binding is **already commented out** ("Temporary disabled, as doesn't work with Google Authenticator app"), and the `remove="True"` line in this package's own `jsregistry.xml` **actively collides**, right now, with a real dependency — `imio.dms.mail`'s own `profiles/default/jsregistry.xml` (found on this machine at `/srv/src/imio.dms.mail/imio/dms/mail/profiles/default/jsregistry.xml:87`) carries ``, i.e. it expects Plone's own `popupforms.js` resource to still exist so it can reposition it. `imio.googleauthenticator`'s `remove="True"` permanently deletes that resource object from `portal_javascripts`, and once deleted, `imio.dms.mail`'s bare reposition entry has nothing to reposition — this breaks **every** `prepOverlay` widget in `imio.dms.mail` (delete/rename dialogs, `imio.pm.wsclient` popups, faceted-nav widgets, etc.), regardless of which package's GenericSetup profile happens to import last. This is not hypothetical: `server.dmsmail`'s `dev.cfg` already lists `imio.googleauthenticator` as an "evaluation only" (MOD-1076) egg alongside the real `imio.dms.mail`, and this package's own `tests/test_setuphandlers.py` already documents "observed on a real `server.dmsmail` deployment, 2026-08-03" for a related jQuery-load-order bug. Coexistence is being tested for real, soon. + +The second load-bearing finding changes how COEX-01 must be implemented. The roadmap states "`id = 'login_form'` on `TokenForm` as the only mechanism," implying a one-line Python class-attribute change is sufficient. It is not: `z3c.form.form.Form.id` is a `@property` used internally by z3c.form, but **neither `plone.z3cform` 0.8.1's `wrappedform.pt`/`form.pt` templates nor the shared `macros.pt` `titlelessform` macro they both delegate to ever render that property onto the `` HTML tag** (verified by reading the installed egg source directly — see `` below). Setting `id = 'login_form'` as a class attribute changes a Python-level property; it does not by itself put `id="login_form"` in the response body Plone's stock, untouched `popupforms.js` searches for (`formselector: 'form#login_form'`). `TokenForm` needs to actually emit that attribute, and the smallest correct fix is a `render()` override that post-processes the rendered HTML — not a template fork, which would just re-introduce the vendoring this phase exists to remove. + +Third, `ska==1.7.5`'s signature only ever covers `auth_user` + `valid_until` (+ an opt-in `extra` dict this package never populates) — read directly from `ska/utils.py`'s `RequestHelper.validate_request_data` and `ska/base.py`'s `Signature.get_base`. Any other query-string key, including the overlay's injected `ajax_load`, is invisible to the signature and cannot break it. The roadmap's open decision is settled: **`ska` tolerates `ajax_load` unconditionally**, with certainty, not "should ignore it." + +Fourth, BUG-01 (open redirect) and BUG-06 (`+`-escaping FIXME) are two ends of the same undefended pipe: `pas_plugin.py::send_2fa_redirect` appends `&next_url={came_from}` with **no quoting at all**, and `browser/forms/token.py::handleSubmit` reads it back and calls `self.request.response.redirect(redirect_url)` with **no on-site check at all**.
