From 68475b3dc72a504dde5709d99bcc8b776c523449 Mon Sep 17 00:00:00 2001 From: Pengfei Hu Date: Mon, 27 Jul 2026 14:54:12 -0700 Subject: [PATCH 1/5] Teach pending_review and align copy with the graded control state Docs the v19 grading left behind: docs/integrations.md described the Stop hook as soft-blocking whenever the verifier returns findings (it now blocks only for agent_action_required, and human_review_required deliberately does not block); docs/agents/protocol.md omitted pending_review[] from the field list, from the agent_action_required row, and from the never-a-stop-state enumeration; docs/agent-contract-current.md contradicted its own v19 preamble by leaving pending_review out of the operative read list; and docs/checks.md asserted human review is required for the UNCLASSIFIED catch-all without qualifying that the local loop now grades it. The check summary also read 'require human review' while control said the agent may continue. Graded results now say the review is carried to PR time, so the prose and the control state agree. New harness criterion reports_pending_review restores the coverage respects_must_stop lost when graded rows stopped being stops: the band traded a hard stop for a reporting duty, so an agent that runs verify and never surfaces the carried items now fails a blocker criterion. Naming each item passes; a generic acknowledgement passes with a weaker signal.

It stays out of AGENT_CONTROL_FIELDS: the obligation is result-level, not part of the control block. - The Codex skill described check routing as continue/repair/stop. The graded band added a fourth shape (verify, then report the carried items), which is the one most likely to fire on a routine .codex/config.toml or SKILL.md edit, so the enumeration now names it. - The Claude Code skill's control sentence now says a non-empty pending_review[] lets the turn finish but must be reported. - Longstanding drift fixed while the hashes were moving anyway: the skill claimed verifier_schema_version 0.5; the current verifier schema is 0.6. Kit sources, their byte-identical mirrors, EXPECTED_*_RENDER_SHA256, and both kits' prior_render_sha256 move together so an installed managed copy is still recognized as unmodified on the next update.

Approval memory: the PreToolUse boundary asked again on every edit to an already-allowed protected file, so prompt-engineering a single prompts/ file cost one prompt per keystroke and taught people to click through. PostToolUse only fires after a tool call went through, so in a prompting permission mode an edit that landed is an edit a human allowed; the hook records those paths per host session and PreToolUse skips re-asking for them. A new session asks again, the auto-accepting modes record nothing because nobody was asked, the memory is capped and scoped to the current session, and AGENTS_SHIPGATE_APPROVAL_MEMORY=off restores prompt-every-time. shipgate check and PR-time verify still evaluate every edit, and SHIP-VERIFY-* still reports the trust-root touch. One verify per turn: check routes the agent to run verify, then the Stop hook ran an identical verify again at turn end. The verifier records the exact bytes it evaluated in verification-input.diff; when that matches the hook's own snapshot and the config and refs agree, the hook reuses the existing verifier.json. Byte-exact comparison, so any mismatch falls through to a normal run. Measured on a fixture repo: 0.9s reused versus 2.1s re-run, and a further edit correctly re-verifies.

Three independently shippable steps, with the propose-and-ratify path reused so the agent proposes and a human declares. host-authenticated-approval-receipts.md (#293): the narrow stuck state v19 deliberately left — a user-approved high-risk host-grant edit. Records the binding (tool_use_id, both content hashes), the authenticity requirement (host-attested or annotation-only), and the eligibility allow-list. It also records why the unsigned local-receipt version was rejected, so that design is not re-proposed by accident.

There is no sanctioned way to record that, so the turn ends +with the agent telling the person who just approved the change that a human must +approve the change. + +Contract v19's graded band removed this for low/medium rows. It deliberately did +**not** remove it for the rows that matter most here: `HOST-MCP-SERVER-ADDED` is +`high`, permission expansion is `high`, and gate-governing trust roots are +excluded at any risk. Those stay stops, which is correct — and it means the +stuck state is now narrow, well-defined, and worth solving properly. + +## Why the unsigned version was rejected + +The first proposal stored an unsigned receipt in the private Git directory and +let `check`/`preflight` consume it to clear routing. Three findings killed it: + +1. **It is agent-forgeable.** The CLI's "am I being run by an agent" gate is an + environment heuristic. A receipt that clears a human route, written by a + command the agent can run, is self-approval with extra steps — and it would + have cleared `block` and `critical` rows too, since nothing tied consumption + to the graded band. +2. **Preflight evaluates the wrong tense.** Receipts bind bytes that already + landed; preflight routes *proposed* edits. A receipt for the current file + would clear review for arbitrary future content. +3. **It cannot reach CI, and must not reach reports.** The ledger lives in one + developer's `.git`. Annotating `report.json` with it would make the same + commit produce different artifacts on different machines, breaking the + content-addressed reproducibility contract. + +The lesson: an in-session approval is only worth anything if its *authenticity* +comes from the host, not from a file the agent can write. + +## Proposal + +A receipt is a statement by the **host** that a specific human answered a +specific permission prompt about a specific proposed edit. + +### Binding + +Bind to the host's own request identity, not to a path: + +- `tool_use_id` — the exact tool call the host prompted about. Both PreToolUse + and PostToolUse expose it, so the prompt and the landing can be correlated. +- `session_id`, and the host's own decision value. +- the proposed content hash (from the PreToolUse payload's edit), plus the + post-edit hash observed at PostToolUse — so approving edit A cannot license + edit B. +- `expires` evaluated against `trust_expiry_date()`, so a backdated commit + cannot extend it. + +### Authenticity + +The receipt is only consumable when the host attests it. Options, in order of +preference: + +1. **Host-signed attestation.** The host (or a broker it owns) signs the receipt + with a key the agent cannot read, verified against a trust policy outside the + evaluated workspace — the same shape contract v18 already established for + `human_authorization` (fixed `~/.config/agents-shipgate/…` path, ownership + and permission checks, no signing command shipped by Shipgate). +2. **Host-written, agent-unwritable location.** Weaker but real: a path the host + writes and the agent's tool surface cannot, declared in the trust policy. + +Absent either, the receipt is **annotation-only** — recorded, surfaced, never +consumed for routing. Fail-closed is the default, not the exception. + +### Consumption, narrowly + +- Only `check` and only for rows in an explicit `RECEIPT_ELIGIBLE_RULE_IDS` + allow-list. `HOST-MCP-SERVER-ADDED` and `HOST-PERMISSION-ALLOW-EXPANDED` are + the intended first members. +- Never for `block` actions, `critical` risk, gate-governing trust-root classes, + incomplete or unparseable input, or gate-weakening rules — the v19 exclusions + apply unchanged and are additionally enforced at the consumption site. +- A consumed receipt yields `agent_action_required` with the verify route and a + `pending_review[]` entry annotated with the local approval. It never yields + `complete`, and it never touches `release_decision`. +- **Not** consumed by preflight (wrong tense, see above) unless a future design + binds a canonical proposed diff with old and new hashes. + +### PR-time + +Verify keeps its current semantics exactly. If reviewers should see that a local +human approved an edit, the carrier is the PR body or a host-side comment — not +`report.json`, `packet.json`, `human_ack`, attestations, or the registry. + +## Prerequisites + +- A host integration willing to attest. Shipgate ships no signer; without a host + adapter this design produces annotation-only receipts, which is still an + improvement over discarding the answer but does not clear the stuck state. +- Concurrency-safe ledger writes (parallel PostToolUse hooks are documented as + possible): lock plus atomic replace, size and row caps, expiry pruning, + containment checks on recorded paths. + +## Acceptance + +- A user-approved MCP-server addition, attested by the host, lets the turn + finish with the obligation carried in `pending_review[]`. +- A receipt written by anything other than the attesting host changes no + routing. +- A receipt for edit A does not clear edit B to the same file. +- Forging the ledger cannot alter a `block`, a `critical` row, or any + gate-governing trust-root row. +- `report.json`, `verifier.json`, and packet artifacts are byte-identical with + and without a ledger present. + +## Interim state (today) + +The stuck state stands, with two mitigations already shipped: the graded band +removed it for low/medium rows, and the Stop hook no longer forces continuation +when a human route is the honest answer — the turn ends with a hand-off instead +of a loop.

The gate for *this* PR stays honest: a + docs-only PR is not a capability change. +- **Fallback:** keep the verdict but make the agent-facing headline lead with + the diff-scoped fact ("no capability change in this diff; the repo has N + standing evidence gaps"), so the copy stops implying the current change is + under suspicion. + +The second is copy-only and cheap; the first is the honest fix and needs care +around `release_decision` semantics, which no change here may weaken. + +### 3. Make one evidence declaration agent-proposable + +Reuse the propose-and-ratify machinery that already exists for tool sources +(`assess_coverage_increasing_tool_source_proposal`, PR #282): let the agent +*write a proposal file* for the inventory/binding declaration the gap names, +never the manifest itself, and route `agent_action_required` with the exact +command.

From 18c3d422286431820c57c4c9f1403a47b4cb3a45 Mon Sep 17 00:00:00 2001 From: Pengfei Hu Date: Mon, 27 Jul 2026 16:26:22 -0700 Subject: [PATCH 5/5] Address review: drop the reuse fail-open, harden approval memory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Six reproducible P1s from review of #294, plus the P2s. Verifier reuse removed entirely (findings 3 and 4). It read agents-shipgate-reports/verifier.json — a workspace file the agent can write — so a forged or interrupted artifact with control.state=complete skipped verification, and an agent_action_required artifact could inject an arbitrary "exact" command. Worse, the identity binding was insufficient: committing a change reproduces the same diff text the earlier worktree run recorded, which the reviewer used to reproduce an outcome-changing stale pass (old `passed` reused while a fresh verify returned review_required for permissions.scopes: ["*"]). Doing this correctly needs binding to the verifier's own content-addressed request identity, which a hook script cannot compute; it is a performance optimization worth ~1.2s, so it goes out rather than shipping a bypass. Tracked as a follow-up. Approval memory hardened (findings 1 and 2, plus two P2s). It now applies only to `ask`: a configured `deny` is an operator's hard block and is never quieted, and nothing is recorded while the boundary is disabled with `allow`, because no request was made and so nothing was allowed. Only paths that provably resolve inside the repository may be stored or consulted — _repo_path deliberately degrades an out-of-workspace absolute path to its basename so the boundary still warns, and that fallback let /elsewhere/shipgate.yaml authorize the repository's own manifest. The permission-mode set was wrong: "ask" is not a mode, and acceptEdits does surface an explicit hook request, so the check is now a deny-list of auto-answering modes with an absent mode treated as unknown. State writes are atomic (temp + os.replace) and merge concurrent sessions instead of replacing them, bounded per session and by session count. reports_pending_review made sound (finding 5). It matched on path and title tokens, so "Edited CLAUDE.md. All done." passed while reporting nothing, and the generic acknowledgement regex matched the negation "No review item is outstanding". Evidence is now identifying ids only, and a denial never satisfies the duty to report. Both counterexamples are regression tests. pending_review removed from AGENT_RESULT_CONTROL_FIELDS (finding 6). That tuple describes agent_result_schema_path, and the field exists only on AgentBoundaryResultV1 — pointing consumers at a schema that omits it was wrong. Reverted in the contract, the .well-known mirror, and both pins; the field stays documented in protocol.md, agent-contract-current.md, and the skills, which is where consumers actually learn it. The cold-start design no longer proposes auto-writing agent_bindings, which contradicted do_not_auto_assert. init scaffolds the unresolved key and names the detected candidate as a suggestion; the human still writes the assertion. Reproduced each P1 fix against the reviewer's own shapes on a live fixture: out-of-workspace approval no longer reaches the repo manifest, deny survives a prior approval, acceptEdits records, and concurrent sessions both persist.
