Code Review
This pull request introduces the acv_latest_nochange_disposition function to identify marker-less maintainer comments indicating that no code changes are needed, along with comprehensive unit tests to verify its behavior under various conditions. It also updates acv_latest_maintainer_disposition to fail closed on unparseable timestamps. The review feedback suggests two valuable improvements: ensuring the portability of the base64 decoding command across different environments and optimizing the ISO-8601 date validation inside the loop to avoid potential external process overhead.

Review mode: triage-approved (single reviewer)
Summary
Adds a maintainer "no change needed" path to both bot-thread resolvers (#2079 AC1–AC6). Authorship is decided by marker and authorAssociation, not login. A recording gh shim captures the node id of every reply the engine posts, and stamp_pass_replies appends <!-- dev-lead:reply --> to only those replies, so dev-lead's own skip notes can't authorize a resolution. The new path fails closed: it needs a full comment page, a fresh re-read with the thread unchanged, no newer REQUIRED disposition and no newer bot comment. It is off until DEV_LEAD_NOCHANGE_EPOCH is set, which is tracked in #2161. Rated MEDIUM, not LOW: this is non-trivial logic that decides when merge-blocking threads get resolved, and it wraps the engine's gh in a PATH shim. Confirms the triage approval. The notes below are non-blocking because the path is disabled, but the first one must be fixed before #2161 turns it on.
Linked issue analysis
Closes #2079. All six acceptance criteria are covered:
- AC1: the no-change case is in
resolve_deferred_bot_threadsand also inresolve_addressed_bot_threads. It does the fresh re-read, the unchanged-thread check, and rejects a newer REQUIRED disposition or bot comment. - AC2:
acv_latest_nochange_dispositionis carried over with its negation, question and hedge rejection, and now uses the marker and association rules. - AC3:
acv_latest_maintainer_dispositionnow returns rc2 (fail closed) when an unparseable timestamp sits next to a valid one. There is a test for this. - AC4 and AC5: a stamped reply, and a marker-less pre-epoch note such as "No change needed in this pass" or "Skipped: false positive", both return rc1. The resolver test confirms a thread whose only no-change comment was posted by the pass stays open.
- AC6: attribution is by recorded reply id, never by time window. The cutoff comes from configuration, and unset disables the path. Tests show a maintainer comment the pass did not post stays byte-identical and still resolves, and that an unset epoch resolves nothing.
The issue's status note says merging this does not close #1743; that is tracked in #2161.
Findings
Non-blocking. Items 1 and 2 must be fixed before #2161 sets DEV_LEAD_NOCHANGE_EPOCH.
- The unstamped-reply retry list doesn't survive between runs (
scripts/dev-lead-fix-reviews.sh,stamp_pass_replies). Reply ids that failed to stamp are saved to${RUNNER_TEMP:-/tmp}/dev-lead-unstamped-replies-<PR>.RUNNER_TEMPis wiped after every job, and nothing caches it. Within one job the list is retried, because both resolvers callstamp_pass_replies. But if stamping keeps failing until the job ends, the next run starts with an empty record and no pending file. The reply is then forgotten: a marker-less, post-epoch,don-petry/MEMBER "no change needed" skip note would read as the maintainer's verdict. That is exactly what AC4 forbids. The code comment saying ids "stay pending until stamped" / "later passes retry it" is only true within one job. Before enabling the path, store the pending ids somewhere durable (for example a PR-scoped marker comment, a cache or an artifact), or fail closed for the whole PR while any recorded reply is unstamped. - The shim only recognizes some ways of posting a reply (
scripts/lib/claim-landing.shcheck()). It matchesaddPullRequestReviewThreadReply,*/replies*andin_reply_to. It misses the GraphQLaddPullRequestReviewComment(input:{inReplyTo:…})form (camelCase) and anything that doesn't go throughghon PATH. A reply posted that way is not recorded, so it is never stamped and fails open. All three prompts use the covered mutation with{ comment { id } }, so this doesn't happen today. Consider adding*inReplyTo*and*addPullRequestReviewComment*to the match list. Matching too broadly is safe here because it only produces UNATTRIBUTED, which fails closed. - Two AC6 test cases are missing. There is no resolver test showing that a
don-petryREQUIRED comment posted mid-pass, which the pass didn't post, stays untouched and still blocks. The maintainer case only uses a no-change body. There is also no explicit test that a top-level comment (gh pr comment) is never recorded or stamped. The shim'spr viewpassthrough test only covers this indirectly. - Minor: in
resolve_addressed_bot_threads, a failed resolve on the no-change path only logs a warning. The deferred resolver also incrementsfailed_countand posts a retry marker. That's acceptable because the next pass retries, but the two resolvers behave differently.
Secret scan: the run_secret_scanning MCP tool is not available in this run. The gitleaks CI check passed.
CI status
All required checks pass: Lint, ShellCheck/shellcheck, bats, unit-tests, CodeQL, SonarCloud, gitleaks, AgentShield, actionlint and the stub/validation suite. The CANCELLED runs (dev-lead / dispatch|ci-relay|resume, one Dismiss, one review / review) are superseded automation dispatches; each has a SUCCESS counterpart or is not a gate. Ecosystem audits that don't apply were SKIPPED. All 27 review threads are resolved. mergeStateStatus is BLOCKED only because an approving review is still required.

Problem
dev-lead: resolve a bot review thread on a maintainer "no change needed" disposition (rebuild of #1799 on #2049's resolver)
From the issue: A bot review thread whose correct answer is "no change needed / false positive" can never be resolved by automation. Under
required_review_thread_resolutionit blocks merge until a human resolves it by hand (#1743). PR #1799 tried to fix this but was closed as superseded: - It went 10 commits behind main and conflicted with #2049. - It has a production bug: dev-lead'sBOT_USERisdon-petry, the same account the maintainer uses.acv_latest_nochange_dispositionskips comments by that login, so the maintainer's own "false positive" reply was always ignored.Risk
Low — changes automation shell logic under scripts/, covered by shellcheck (--severity=warning) and the bats suite.
Test plan
