Fixes bead mr-ik7 (P2): the pr-ready gate could silently retire a committed review log that still listed a blocker no ledger ever held.

The bug

gateReviewLogs decided a log was historical via the lenient reconcileReview → reviewstate.ClassifyReviewFindings, which skips any finding ID the ledger does not know. So resolving (fixing or overriding) the IDs a local ledger happened to hold retired a log that also listed an unknown blocker — while status (which uses the strict LogResolvedInLedger, "unknown ID = unvouched blocker") still reported it blocking. A finding silently ceased to gate.

The fix

  • Summary.BlockingFindingIDs (new): parseMarkdown now records the finding IDs under the log's first ## Blocking Findings section (level-2 or level-3). Only the first section counts, so a ## Blocking Findings quoted from an embedded PR description can't re-open it and leak foreign IDs.
  • reviewstate.LogBlockersResolvedInLedger (new gate predicate): strict about the log's BLOCKING IDs — each must be a ledger-known, blocking-class, terminally-resolved row — while deliberately not blocking on the advisory/quoted IDs that also land in FindingIDs (those would otherwise pin a log forever on something nobody can act on). BlockingFindingCount (from the run record) is the tripwire against a pruned/unknown blocker; a known-open blocker anywhere still blocks; a log with no such section falls back to the strict LogResolvedInLedger.
  • gateReviewLogs now uses it. status keeps the stricter LogResolvedInLedger; the rendered evidence keeps its plain lenient reading (it renders, it does not gate).

Review

Reviewed with adversarial review-loop rounds (pi subagents). The rounds caught a first cut that reused LogResolvedInLedger wholesale — which over-blocks, because real logs carry advisory mrvf- IDs under ## Advisory Findings that the #188 importer never makes known — and the parser section-injection path. metareview review pr-ready → PASS. Full suite, go vet, golangci-lint clean; internal/reviewlog, internal/reviewstate, internal/prready at 100% coverage.

Residual advisory (confirmed, filed, not a blocker): the gate still trusts a committed log's markdown to enumerate its blockers when there is no local run record (the pre-existing #147 markdown-trust surface); the new predicate is strictly stricter than the one it replaces.


Note

Medium Risk
Changes when pr-ready clears historical review logs—a core merge gate—with new markdown parsing; behavior is fail-closed for unknown blockers but could leave more logs blocking than before.

Overview
Fixes mr-ik7: pr-ready no longer drops a review log from the gate just because the ledger resolved every finding ID it knew about, while an unknown blocking ID from the log’s ## Blocking Findings section was still unvouched.

Parsing: reviewlog.Summary gains BlockingFindingIDs, filled from the first ## / ### Blocking Findings section using declared ### mrvf-… headings only (not prose quotes, not fenced examples, not a second quoted section). Fence-aware parsing avoids treating code blocks as structure.

Gate logic: New reviewstate.LogBlockersResolvedInLedger requires each blocking-section ID to be ledger-known and terminally resolved, honors BlockingFindingCount from the run record, still blocks on any open blocker-class row in FindingIDs, and ignores unknown advisory IDs that would otherwise pin logs forever. Logs without a blocking section fall back to strict LogResolvedInLedger. gateReviewLogs switches from lenient reconcileReview to this predicate; status and evidence rendering stay on their existing stricter/lenient paths.

Docs & tests: ARCHITECTURE.md documents the split; unit tests cover parsing edge cases and gate behavior (unknown blockers vs advisory-only unknowns).

… (mr-ik7)

gateReviewLogs used the lenient reconcileReview, whose ClassifyReviewFindings
skips finding IDs the ledger does not know — so resolving the IDs a ledger
happened to know retired a committed log that also listed a blocker nobody's
ledger ever held. The gate now uses the same strict reviewstate.LogResolvedInLedger
predicate status uses (an unknown ID is an unvouched blocker); the rendered
evidence keeps its lenient reading. Regression test + ARCHITECTURE note.

The gate now uses a new reviewstate.LogBlockersResolvedInLedger, strict about the
log's BLOCKING findings only: it iterates the new Summary.BlockingFindingIDs
(parsed from the log's '## Blocking Findings' section), requires each to be a
known, resolved blocker-class row, and uses BlockingFindingCount as the tripwire
against a pruned/unknown blocker. An advisory or quoted id is not a blocker and
must not keep a log unresolved forever. The rendered evidence keeps its lenient
reading; status keeps the stricter LogResolvedInLedger.

Summary by CodeRabbit

  • Bug Fixes
    • PR-ready checks now keep a review log as a gate input when a listed blocking finding is unknown, unresolved, or not sufficiently confirmed in the findings ledger. Logs can clear the gate only when their blocking findings meet the required resolution criteria.
    • Advisory findings and quoted finding IDs do not prevent a review log from clearing the gate.
    • Review status checks continue to require all findings to be known and an authenticated run record; rendered evidence does not affect gate decisions.

Walkthrough

Review-log parsing now identifies blocker IDs from the first “Blocking Findings” section. PR-ready gate filtering checks those IDs against the findings ledger. The pull request also adds metareview records for the blocker change and a separate review-loop run.

Merge Risk: 🟡 Moderate · up to 038b1

The new pr-ready gate decides from committed review-log markdown which findings are blockers. Two parsing gaps remain. Example code inside a finding can hide a later blocker, so a log with an unresolved blocker can be cleared. An ID mentioned in a finding's evidence text can also block a log that should clear. These gaps should be fixed before merge.

- Line 187: Update the section-state parsing around headingTitle to track fenced
code blocks before processing headings; only treat headings outside fences as
opening or closing the blocking section. Recognize a closing fence only when it
uses the opening character family, is at least as long, and has only trailing
whitespace. Add a regression test for the described ledger with no local blocker
count, verifying the unknown blocker is not treated as resolved.
- Around line 271-272: Update the ID collection in the review-log parsing flow
around `inBlockingFindings` so `BlockingFindingIDs` receives only IDs from
finding declarations, such as headings, not references found in descriptions or
evidence; keep all scraped IDs in `FindingIDs`. Add a test showing an unknown ID
in a resolved blocker’s description does not prevent
`LogBlockersResolvedInLedger` from returning true.

CodeRabbit on #216: a quoted mrvf- id in a finding's evidence (or inside a fenced
code block) must not join the blocking set, and a heading inside a fence must not
change the section state. BlockingFindingIDs now takes only '### mrvf-...'
declaration headings, and parseMarkdown skips fenced content.
