I reconstructed the gate's new section from the spec and verified it end-to-end against a synthetic git repo (10/10 cases pass). Solution written to ~/work/SOLUTION.md; the runnable artifacts are ~/work/record-commits-snippet.sh and ~/work/test-record-commits.sh.
===COMMITS=== record values, not just the ===GIT=== headRepo: Hermes-DAGger/<project> · File: scripts/sync-scheduler-tick-postcheck.sh
Commit base: f906805 · New fail reason: record-sha-not-in-repo
The postcheck gate built a normalised claim text from the run's probe sources (union of run.jsonl / run.log / run.grouped.jsonl / globbed logs plus the role.db checkpoint read through the sqlite3 CLI, WAL-transparent, both escaping depths flattened), but then validated only the first token of the record — the ===GIT=== head — against git -C "$REPO" rev-parse HEAD.
A record is a claim set: ===GIT=== (head/branch/dirty), ===COMMITS=== (<sha> <subject> lines) and ===CI=== (status) are one unit produced by the same upstream. Validating its first field only checks shape, not truth. A fabricating LLM-mediated tool executor can invent well-formed probe output: keep the head line correct (or rewrite it to the host head) and fill ===COMMITS=== with plausible hex shas. Every one of those objects can be absent from the repo (and from every repo on the host) while the gate exits 0 and writes no failure artifact. "The claim source is now readable" is not "the claim values are true."
Add a section-4b check that runs only after the existing ===GIT=== head checks agree (a wrong head keeps its own reason). It extracts the ===COMMITS=== section from the same normalised claim text the head path already builds, treats each entry's line-leading token as the claim, and runs git cat-file -e "$tok^{commit}". On the first unresolvable object it prints a loud stderr line naming sha + repo + run dir, writes the fail JSON with the new reason record-sha-not-in-repo, and exits 2.
Three boundaries are encoded:
git rev-parse --disambiguate=<tok> yielding ≥2 candidates makes git refuse the abbreviation, which cat-file reports as the same failure class as absent. Skip such tokens (loudly).NOTE, never a failure (real subjects echo judge/history ids, e.g. ...verdict 27d706fb / history 0be9bccc). A section with no <sha> <subject> entry at all falls back to a strict shape rule: every harvested token is validated, so free-text fabrication cannot hide behind the shape exception.The harvest is confined to the ===COMMITS=== section only — never ===CI===/===EVENTS===/===SCHED===, whose hex belongs to other contracts.
In scripts/sync-scheduler-tick-postcheck.sh, locate the ===GIT=== head validation block (the code that compares the head token to git -C "$REPO" rev-parse HEAD and writes the head-mismatch fail JSON). Insert the function below immediately before that block, and the invocation immediately after the block's success path. Rename the arguments to the already-in-scope variables if they differ (the normalised claim text variable, $REPO, the run dir, and the fail-JSON path used by the head path).

{"description": "Symptom: a post-hoc host ground-truth gate for a data-sync pipeline passed runs whose persisted records were FABRICATED, silently (exit 0, no failure artifact), even though the same gate had just been taught to read the record's authoritative claim source. The gate validated exactly ONE token - the ===GIT=== head - against `git -C $REPO rev-parse HEAD`. A fabricated run whose head token happened to match the host head therefore passed while every entry in the ===COMMITS=== record named a commit object that does not exist anywhere in the repo (and, in the wider incidents, in any repo on the host). Reproduction: take a real fabricated run dir whose probe text lives in the run's role.db checkpoints, rewrite ONLY the ===GIT=== head line to the repo's real current head, leave the four invented ===COMMITS=== entries (e.g. b86231a/8190e4c/dc6f2b3/5793d01 on a Rust repo that never had them), run the gate -> exit 0. `git cat-file -e <sha>^{commit}` proves each claimed commit ABSENT in the canonical repo and in a host-wide .git sweep.\n\nRoot cause: validation depth. 'The claim source is now readable' (previous fix) is not 'the claim VALUES are true'.
