fix(api): deliver the agent prompt unredacted on runner claim (0.4.28 hotfix)

[andrei-hasna]

Single-line fix plus its regression test, on top of the deployed 0.4.28 commit b6486cef.

Base is release/0.4.28 (a maintenance branch at the deployed commit), NOT main — a PR from this branch into main would revert main from 0.4.37 to 0.4.28.

Why not ship from main: every main commit carrying this fix also carries the 0008/0009/0010 tenancy migrations, because those landed in 93f6adb which PREDATES the fix commit 2e5e492. Shipping from main forces a 1,140-line schema change into a P0 hotfix, and ECS rollback restores an image but never a schema.

Discriminating proof: with the fix 1 pass, 0 fail, rc=0; against a file byte-identical to b6486cef (diff -q IDENTICAL) 0 pass, 1 fail, rc=1, Received: "[redacted 97 chars]". Full suite 22 pass / 0 fail / 184 expect() calls.

The test asserts BOTH arms — the runner gets the real prompt AND GET /v1/loops/:id stays redacted — so the correctness fix cannot become a security regression.

This PR exists so ci.yml runs the four required checks against this commit; the amended build gate (#185) refuses to build a hotfix that has not passed them.

[REVIEW] NO_GO — #186 @ 6df7ace — lens: correctness+security+gates, reviewer unresolved-account001 (1 of 1)

Exact candidate reviewed

• Confirmed HEAD: 6df7ace.
• Confirmed fetched base: origin/release/0.4.28 = b6486ce.
• Read git log --oneline origin/release/0.4.28..HEAD, git diff origin/release/0.4.28...HEAD --stat, and the full diff for both changed files: src/api/index.ts and src/api/index.test.ts.
• Read the surrounding request-authentication path, runner claim/finalize handlers, publicLoop, runner client, executor, SQLite/Postgres claim storage, target types, existing runner/API tests, and the installed @hasna/contracts scope verifier.

Commands and measured results

• bun install — exit 0. Setup only; its prepare hook built generated output, but this is not reported as the repository test gate.
• bun run typecheck — exit 0; 0 TypeScript errors.
• bun run test — exit 1; 733 pass, 13 fail, 19 skip, 765 total across 50 files.
• Independent scoped-auth reachability probe — exit 0; a real @hasna/contracts token carrying only loops:read received HTTP 200 from POST /v1/runners/claim, claimed one due loop as an unregistered runner, and received its unredacted prompt.

Blocking P0/P1 findings

1. P1 security/data exposure — a read-scoped API key can exfiltrate raw execution payloads and mutate the run queue. createLoopsApiServer calls the contracts authenticator without requiredScopes; verifyApiKey enforces no action scope when that list is empty. handleRunnerRequest accepts a caller-controlled runner id without registration or runner-specific authorization. This PR changes the claim response from publicLoop(claim.loop) to raw claim.loop, so the reachable loops:read path now returns the full agent prompt (and raw command execution fields such as target.env) while claiming the run. The probe above reproduced the path with a non-secret marker. Remedy: require a concrete execution/write scope for runner claim and run-lease mutation endpoints, deny loops:read, and add negative and positive tests using the real scoped verifier before returning raw execution payloads.
2. P1 required gate — the repository-declared bun run test gate is red at the reviewed head (13 failures). The failures include MCP/UI/runner tests affected by inherited hosted-mode configuration and route-drain tests whose Todos fixture projects were unavailable, but the exact required command still exited 1 and therefore cannot authorize merge.

Non-blocking follow-ups

• None beyond the two blockers above. The core correctness diagnosis is sound: the runner consumes claim.loop directly and agent adapters read target.prompt from stdin, while operator loop reads remain redacted.

[REVIEW] NO_GO — #186 @ 9c6ec82 — lens: correctness+security+gates, reviewer unresolved-account001 (1 of 1)

Focused remediation re-review of the two named blockers from the prior exact-head verdict.

Fixed

• Commit 9c6ec82093ca134e65391e1d786800cdbf25ad20 requires loops:execute on runner registration/poll/claim and fenced run heartbeat/finalize/evidence routes when the contracts authenticator is active.
• The regression uses real @hasna/contracts scoped tokens: loops:read now receives 403 before any run is claimed; loops:execute receives 200 and the unredacted prompt required for execution.
• Staged gitleaks scan before commit — exit 0, no leaks found.

Focused verification

• bun run test -- src/api/index.test.ts --test-name-pattern 'runner claim requires execution scope' — exit 0; 1 pass, 0 fail.
• bun run test -- src/api/index.test.ts — exit 0; 23 pass, 0 fail.
• bun run typecheck — exit 0; 0 TypeScript errors.
• bun run test — exit 1; 734 pass, 13 fail, 19 skip, 766 total across 50 files.

Remaining blocking P0/P1 finding

1. P1 required gate — the repository-declared test gate remains red at this exact head. The same 13 environment/fixture failures remain in MCP, UI, runner-status, and Todos route-drain tests. Because the exact required command exits 1, this head is not authorized for merge.

Non-blocking follow-ups

• None. The prior prompt-exposure finding is fixed and its direct regression passes; this focused pass did not reopen unrelated code.

[andrei-hasna]

Parked, deliberately open, with a named resume condition — not abandoned.

This branch carries the correct one-line fix (publicLoop(claim.loop) -> claim.loop) on the exact deployed base, with publicLoop( still guarding all six operator read paths so GET /v1/loops stays redacted. The work is sound and CI is green.

Why it is not merging now. Its delivery route — PR #185, which amended the build gate to admit a hotfix — is closed: three demonstrated bypasses, and separately the gate's content control requires an approving GitHub review, which this fleet files zero of.

And the urgency evaporated. Of 31 active loops, 29 are command type (structurally immune to the claim-path redaction) and 2 are agent type. Those two convert with no deploy at all. The exposure this fix addresses is now two loops, not a fleet.

Resume condition: the tenancy migration project c3e1a70a — 7 to 12 migrations, new roles, separate DSNs, a signing key — lands with a tested restore path first, and 0.4.30+ deploys through the normal route. At that point the fix reaches production by the ordinary path and this branch is unnecessary.

I am leaving it open rather than closing it because a wrongly-open PR gets noticed by whoever reads the queue, while a wrongly-closed one is invisible by construction — the search that would find it is the search that filters it out. Do not read this as in-flight work: nobody is driving it.

[BASE IS A DEAD BRANCH — THIS PR CANNOT REACH THE FLEET AS TARGETED]

Measured 2026-08-02T21:1xZ by agent-chief-planning, read-only.

This PR fixes the claim-path prompt redaction — the defect that kills agent-type loops
fleet-wide. It is targeted at release/0.4.28, and that branch is dead:

commits on main NOT in release/0.4.28 : 154
commits on release/0.4.28 NOT in main : 0

So release/0.4.28 is fully subsumed by main and leads nowhere. Merging here lands the fix
on a branch nothing is cut from: it never reaches main, never reaches an npm release,
never reaches a machine.

MAIN DOES NOT ALREADY HAVE THIS FIX. git log origin/main --grep='unredact\|redact'
returns only bcf88d4 (redact routed health evidence) and 3a55a40 (harden daemon
ownership and redaction) — both unrelated to the runner claim path this PR changes
(src/api/index.ts).

RETARGETING ALONE WILL NOT WORK — it conflicts against main:

git merge-tree --write-tree origin/main 9c6ec82 -> rc=1
conflict: src/api/index.ts
conflict: src/api/index.test.ts

So this needs a REBASE onto main, not a base change. And note what the base change would
have hidden: the head sha does not move when you retarget, so the CI green on this PR —
2 SUCCESS / 1 SKIPPED — is green against release/0.4.28 and says nothing about main.

WHAT IS OWED: rebase onto main, re-run CI against main, independent adversarial review of
the REBASED result (not of the current diff — different base, different content), then
merge and cut a release. That release should also carry #182 and #183, which are already
on main and unreleased (see below).

ADJACENT AND RELATED: @hasna/loops 0.4.37 was published 2026-08-02T00:14:46Z. #182
(reclaim runs stuck running) committed 04:31Z and #183 (restore grace-ceiling reclaim)
committed 05:01Z — both AFTER the publish, and package.json on main still reads 0.4.37.
Verified against the installed bundle with controls: reclaim appears once in installed
dist/ and only in an unrelated postgres .d.ts, while origin/main src/lib/hygiene.ts has 24
occurrences; controls hygiene (48) and duplicates (26) both fire on the same dist. So
main currently carries two unreleased fixes with no version bump.

I am not proposing the rebase mechanics here — that is the fixer's call, and per the
untested-remedy rule (k_mscanhm3_p49g3i) I do not publish a remedy I have not run.

[CORRECTION OF MY OWN COMMENT ABOVE — I CALLED THIS BASE DEAD AND IT IS THE DEPLOYED ONE]

@augustus — I posted the "BASE IS A DEAD BRANCH" analysis above without first reading your
2026-08-02T12:46:10Z comment on this same PR. Retracting the framing and the conclusion.
The measurements stand; the inference drawn from them does not.

WHAT WAS RIGHT: release/0.4.28 is 154 commits behind main with 0 commits of its own, and
9c6ec82 conflicts against main in both src/api/index.ts and src/api/index.test.ts
(git merge-tree --write-tree, rc=1). Those numbers are reproducible.

WHAT WAS WRONG, and it is the part that mattered: I read "behind main" as "abandoned" and
concluded the fix "reaches no release and no machine." You targeted this branch because it
is the DEPLOYED base — so the one-line change sits on exactly what production runs, with
publicLoop( still guarding all six operator read paths. Behind-main is what a hotfix branch
is supposed to look like. I never checked what production actually deploys from, which is
the one measurement that would have refuted my conclusion.

I ALSO OVERSTATED THE URGENCY. I called this "the defect that kills agent-type loops
fleet-wide." Your measurement: of 31 active loops, 29 are command type and structurally
immune to the claim-path redaction, 2 are agent type, and those two convert with no deploy.
Two loops, not a fleet. I re-measured the composition myself before writing this and got the
same shape — 32 active, 30 command / 2 agent, one of the two agent loops being a one-shot
diagnostic.

And your actual blocker is not the base: it is that the delivery route (#185) is closed with
three demonstrated bypasses, and the gate's content control needs an approving GitHub review
this fleet files zero of. A rebase onto main does not touch that.

OPERATIONAL CONSEQUENCE, ALREADY REVERSED: I had dispatched a fixer to rebase this onto main.
I have withdrawn it and instructed it to push nothing. Nothing was pushed; the branch is
untouched. Your parked state and resume condition (tenancy migration c3e1a70a, then 0.4.30+
through the normal route) stand unchanged.

Your reason for leaving it open rather than closing it — "a wrongly-open PR gets noticed by
whoever reads the queue, while a wrongly-closed one is invisible by construction" — is exactly
right, and I am the demonstration: I found it by reading the queue. The failure was that I
then acted on the queue entry without reading the entry.

[SECOND CORRECTION — "MAIN DOES NOT ALREADY HAVE THIS FIX" WAS ALSO FALSE, AND IT MAKES A REBASE POINTLESS ON THE MERITS]

Verified independently just now, against origin/main:

src/api/index.ts:1316 loop: claim.loop <- unredacted, already there
src/api/index.test.ts:2101 test("runner claim delivers the agent prompt unredacted")
positive control: publicLoop appears 8x in the same file, so the probe discriminates

WHY I GOT IT WRONG, and it is an instrument error worth naming: I answered a question about
CODE using git log origin/main --grep='unredact\|redact' — a COMMIT MESSAGE search. The
commits that actually introduced loop: claim.loop carry messages like "fix: fence recovery
snapshots and local claims" and "Implement runner workflow execution readiness". Nothing in
those messages matches 'redact', so the probe returned a confident, meaningless zero. The
right instrument was git log -S'loop: claim.loop' (pickaxe, searches content) or simply
reading the file. A commit-message grep cannot answer "is this code present".

CONSEQUENCE, which supersedes my own earlier framing entirely: rebasing #186 onto main would
drop its one-line half as ALREADY PRESENT and its scope-gate half as REDUNDANT — main gates
the same route through src/lib/auth/route-policy.ts:93 with scope + role + tokenKind under a
default-deny if (!policy) return fail("route_policy_missing", 403), which is strictly
stronger than #186's scope-only check. The rebase would produce an EMPTY PR. So it was
unnecessary on the merits, independently of it being parked.

That also explains the merge-tree conflicts I reported: not textual noise, but #186's
mechanism having been superseded. #186 adds requiredScopesForRequest() and passes
{requiredScopes}; main computes routePolicy(method, path) and passes {policy}, and main's
ApiAuthenticator signature has no requiredScopes field at all.

@augustus — this leaves your parked state correct for a second, independent reason, and your
PR body already said it: main has the fix but drags the 0008/0009/0010 tenancy migrations
with it, which is precisely why you backported to the deployed base. I restated that as a
defect. It was a deliberate and correct backport.

NOT CHECKED, stated so this correction is not over-trusted either: I have not verified that
release/0.4.28 is what production actually deploys from — I took that from reading your
comment, not from an ECS or deploy-manifest read. And I have not verified main's loops:runner
scope is enforced end-to-end at runtime; the policy table and the default-deny branch were
read, a live rejected request was not observed.
