A tree-SHA-keyed inventory caches validated PR presence. Replay stops only when no indexes exist; it fails when indexes exist or the evidence is incomplete or changes during the check.

Once the immutable attempts directory grows, this request cannot prove that a PR has no indexes: GitHub's Get repository content endpoint has a 1,000-file directory limit. Since index filenames are SHA-256 hashes and these files accumulate indefinitely, the requested PR's index can fall outside the returned subset, causing this function to return false and accept a missing ledger as an ordinary no-op—the fail-open condition this guard is intended to prevent. The subsequent per-file requests also consume up to roughly 1,000 API calls per ledgerless replay; use a complete pinned-tree lookup or a PR-addressable index instead.
Useful? React with 👍 / 👎.

- Line 998: Replace the Contents API directory listing used to establish
attempt-index absence with a complete tree lookup or PR-specific presence record
so an index beyond the 1,000-file limit is not treated as absent. Apply the same
change at .github/scripts/keepalive_authority_state.js:998-998 and
templates/consumer-repo/.github/scripts/keepalive_authority_state.js:998-998.
- Line 1017: Update both `.github/scripts/keepalive_authority_state.js` at line
1017 and `templates/consumer-repo/.github/scripts/keepalive_authority_state.js`
at line 1017: in the attempt-index scan, fail closed by throwing when a listed
index file has invalid metadata or its content cannot be validated or parsed,
rather than skipping it and treating the missing ledger as an ordinary-PR no-op.
Review comments at @docs/keepalive/GoalsAndPlumbing.md:
- Line 128: Update the replay description to clarify that it scans the
attempt-index directory only to verify whether a PR with a missing ledger has
any attempt indexes; retain the statement that replay does not scan historical
indexes for other purposes.

Implement bounded guard so 404 is accepted only after confirming the PR is ordinary; authority candidates fail closed. This prevents silently abandoning reconciliation for PRs that previously entered the challenge path when their authority ledger is missing. - Add hasAttemptIndexesForPr() to check if a PR has any attempt indexes - Modify replayReporterAuthority() to check for attempt indexes when authority ledger is missing (null from readAuthorityStateForReplay) - If PR has attempt indexes, fail closed with clear error - If PR has no attempt indexes, treat as ordinary and accept empty replay - Add regression test for authority candidate with missing ledger - Update existing test to verify hasAttemptIndexes is called - Update documentation to reflect new bounded behavior - Integrate with the existing readAuthorityStateForReplay tree-snapshot approach Fixes P2 PRRT_kwDOQprj9M6op53C: accepting a missing authority ledger as an empty replay without independently classifying the PR can silently abandon reconciliation for a PR that previously entered the challenge path.

Addressed the missing-ledger attempt-presence findings in Validation: 81 focused Node tests pass, including a 1,001-index case and malformed/unavailable evidence on both source and consumer surfaces. Template sync, completeness, byte parity, and drift checks pass (zero unallowlisted drift); Pushed at 2026-10-06T23:44:57Z; earliest review-floor completion is 23:51:57Z for this exact head. No merge or auto-merge. Orphan PR Steward owns the next pass: inspect fresh reviewer disposition, complete current-head check suites/runs and expected/required topology, clear all active non-outdated threads, then revalidate the unchanged head and normal merge gate. Pending CI alone does not authorize a merge. |

and negative results keyed by PR number, returning the cached result on later
sweeps instead of rescanning every index blob. Use a full scan to populate
missing legacy PR records, and keep cached records consistent whenever new

codex/keepalive-replay-missing-ledger-20261001, tip269931c7bf842c1b94f54371eb0be960374853dc. Its latest commit is from 2026-10-03T17:46:26Z (over three days old);git cherry origin/main <tip>finds one unique patch. Prior #3672/#3722 are closed, and the branch now includes a later authority-index guard not present on main. At recovery time no linked issue was established; the current bounded source repair is tracked in #3793.This regular PR makes the remaining patch reviewable; no auto-merge label is applied. It requires ordinary review, current source/campaign ownership reconciliation, full expected checks, and the exact-head review floor. The orphan sweep does not establish acceptance or authorize a merge.

Closes #3793
Reviewed Repo Merge Verify Closer (
imi-merge-verify-closer, ACTIVE hourly) and the existing issue keepalive own implementation in this PR. Do not open a duplicate PR. Next action: implement and validate bounded durable positive/negative PR presence with legacy backfill, write consistency and fail-closed concurrency, then settle Major thread PRRT_kwDOQprj9M6ps0Uu. Full acceptance and exact-head evidence are in #3793. The old consumer-export P1 was independently disproved on head6102cc666 and resolved with executable default-consumer proof. Successful Gate does not clear the remaining Major finding.Original intake provenance: authorized closer orphan sweep recovered an existing pushed branch; previous local_request ref was automation:imi-merge-verify-closer:orphan-sweep:2026-10-06. This historical provenance is preserved, while current source/verification ownership is issue#3793.
