   wouldMutate stays false when only repairs happen

   When pruneMissingTranscriptEntries repairs a stale sessionFile but prunes nothing, it returns 0. Both the dry-run summary (missing > 0 || ...) and the applied summary (missingApplied > 0 || ...) use that count as their sole signal from this function, so wouldMutate is reported as false even though the store was mutated. A caller or monitoring script that inspects wouldMutate in the JSON output would incorrectly conclude cleanup was a no-op when in reality session metadata was rewritten.

   **`wouldMutate` stays `false` when only repairs happen**
   
   When `pruneMissingTranscriptEntries` repairs a stale `sessionFile` but prunes nothing, it returns `0`. Both the dry-run summary (`missing > 0 || ...`) and the applied summary (`missingApplied > 0 || ...`) use that count as their sole signal from this function, so `wouldMutate` is reported as `false` even though the store was mutated. A caller or monitoring script that inspects `wouldMutate` in the JSON output would incorrectly conclude cleanup was a no-op when in reality session metadata was rewritten.

• ClawSweeper keeps one durable marker-backed review comment per issue or PR.
• Re-runs edit this comment so the latest verdict, findings, and automation markers stay together instead of adding duplicate bot comments.
• A fresh review can be triggered by eligible @clawsweeper re-review comments, exact-item GitHub events, scheduled/background review runs, or manual workflow dispatch.
• PR/issue authors and users with repository write access can comment @clawsweeper re-review or @clawsweeper re-run on an open PR or issue to request a fresh review only.
• Maintainers can also comment @clawsweeper review to request a fresh review only.
• Fresh-review commands do not start repair, autofix, rebase, CI repair, or automerge.
• Maintainer-only repair and merge flows require explicit commands such as @clawsweeper autofix, @clawsweeper automerge, @clawsweeper fix ci, or @clawsweeper address review.
• Maintainers can comment @clawsweeper explain to ask for more context, or @clawsweeper stop to stop active automation.

• 🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
• 🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
• 🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
• 🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
• 🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
• 🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
• 🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.

Best possible solution:

Port the fallback-and-repair behavior into src/config/sessions/cleanup-service.ts, count repaired paths in cleanup summaries, preserve true-missing pruning, add service-level regression coverage, and require redacted CLI proof before merge.

Do we have a high-confidence way to reproduce the issue?

Yes, at source level. A store entry with a valid sessionId, a missing stale generated sessionFile, and an existing canonical <sessionId>.jsonl still follows the single resolved-path cleanup check on current main and would be pruned.

Is this the best way to solve the issue?

No, not as submitted. The fallback-and-repair direction is the right narrow fix, but it needs to be ported to the cleanup service, count repair mutations, and include real behavior proof.

Label justifications:

• P2: This is a focused session cleanup safety fix for a real linked bug, with limited surface area but meaningful session-history impact.
• merge-risk: 🚨 session-state: The PR changes cleanup behavior that preserves, prunes, and rewrites session transcript metadata, so an incomplete merge can stale or mis-associate session state.
• rating: 🧂 unranked krab: Current PR rating is 🧂 unranked krab because proof is 🧂 unranked krab, patch quality is 🧂 unranked krab, and Useful bug-fix direction, but the PR is not quality-ready because proof is missing and the patch is stale/incomplete for current main.
• status: 📣 needs proof: The PR needs real behavior proof before ClawSweeper can clear the contributor ask. Needs real behavior proof before merge: The PR body describes local verification, but it has no inspectable after-fix terminal output, logs, screenshot, recording, copied live output, or linked artifact; the contributor should add redacted proof and update the PR body to trigger a fresh review, or ask a maintainer to comment @clawsweeper re-review.

Full review comments:

• [P2] Port the fallback into the cleanup service — src/commands/sessions-cleanup.ts:152-164
  Current main runs sessions cleanup through runSessionsCleanup, whose active pruneMissingTranscriptEntries lives in src/config/sessions/cleanup-service.ts. Keeping this fallback only in the stale command-local helper will not fix current main after rebase; move the behavior and coverage to the service path.
  Confidence: 0.9
• [P2] Report repaired transcript paths as mutations — src/commands/sessions-cleanup.ts:164-165
  When this branch repairs entry.sessionFile, the helper still returns only the prune count. Repair-only dry runs or applied JSON summaries can therefore show missing: 0 and wouldMutate: false even though cleanup rewrote session metadata; return a repaired count or mutation flag and include it in summary accounting.
  Confidence: 0.95

Overall correctness: patch is incorrect

What I checked:

• Current active cleanup path still uses one resolved transcript path: On current main, pruneMissingTranscriptEntries lives in src/config/sessions/cleanup-service.ts, resolves resolveSessionFilePath(entry.sessionId, entry, ...) once, and deletes the store entry when that one path is absent; there is no canonical transcript fallback or metadata repair in the active service path. (src/config/sessions/cleanup-service.ts:198, 110042d840bb)
• Command now delegates cleanup to the service: The CLI command calls runSessionsCleanup from src/config/sessions.js, so a fix kept in the old command-local helper will not cover current-main cleanup behavior after rebase. (src/commands/sessions-cleanup.ts:219, 110042d840bb)
• Repair-only mutation accounting is missing: Current summary logic sets wouldMutate from prune/count signals; the PR's helper mutates entry.sessionFile but still returns only the removed count, so repair-only cleanup can be reported as a no-op unless repairs are counted separately. (src/config/sessions/cleanup-service.ts:354, 110042d840bb)
• Transcript candidate contract supports the requested fallback model: resolveSessionFilePath prefers a persisted sessionFile, while resolveSessionTranscriptCandidates also adds the store-directory canonical <sessionId>.jsonl candidate; cleanup currently does not use that broader candidate behavior. (src/gateway/session-transcript-files.fs.ts:71, 110042d840bb)
• PR diff targets stale command-local code: The PR commit changes only src/commands/sessions-cleanup.ts and src/commands/sessions-cleanup.test.ts, adding fallback and repair logic to the old command helper rather than the current cleanup service. (src/commands/sessions-cleanup.ts:150, 881bd5fbc1a2)
• GitHub state and related item context: Live PR metadata shows this PR closes the still-open canonical issue, is currently conflicting, has a failed Real behavior proof check, and prior review comments already flagged the mutation-accounting gap.

Codex review notes: model gpt-5.5, reasoning high; reviewed against 110042d840bb.

• The egg game starts only after the PR passes the real-behavior proof check.
• Before that, no creature or rarity is rolled. The treat waits for real proof.
• This is still just collectible flavor: proof affects review readiness, not creature quality.
