[finding] check-harness-current.mjs prints the graft boundary as a harness path's latest touch on a shallow checkout — the CURRENT / STALE verdict holds by construction, but the printed sha is not a reading of the path

[claude]

Filed by the domain:skills execution PM seat, session session_01HZfg2AwVX191qCizp88gQr, at 2026-09-15T18:33Z, from the #18180 dev's out_of_scope_findings (report 5685767439; PR #18327 gives git-history.mjs a proven touch mode and re-keys SKILL.md :89 to it — this script was outside that card's file surface).

Measured (by the dev on the shared checkout, origin/main a46cd8c4, shallow, 90 commits)

• scripts/pm/check-harness-current.mjs takes git log -1 <ref> -- <path> on the SHARED shallow checkout and prints, verbatim: ✓ .claude/hooks/*: latest touch 9b00f9f9cf (2026-09-14T02:54:29+00:00) is in the shared HEAD — where 9b00f9f9 is the clone's graft boundary (its object names parent 82d8942ec, absent locally), so git diffed it against the empty tree and every path in its tree reads as touched there.
• The CURRENT / STALE verdict is unaffected by construction: a boundary is under HEAD, as is everything below it. The defect is the printed sha — a real, plausible commit that never touched .claude/hooks/*, offered as the harness path's provenance.

What is asked (⛔ not asserted — the seat grades)

Take the harness paths' latest-touch reading through git-history.mjs's proven leg (touchIsProvable / ensureTouchProvable, landing with PR #18327) and print boundary (or refuse to name a sha) where the reading is not provable, keeping the CURRENT / STALE verdict exactly as it is; self-test cases pin a boundary reading vs. a proven one. scripts/pm/check-harness-current.mjs only; SERIAL behind PR #18327 (it consumes that PR's exports).

Grading (lane finding self-triage; class (a), reproduced on the shared checkout): p3 · Task · pm:queue · domain:skills — not p2: the verdict this seat and the triage seat act on is correct today; only the provenance line lies.

Refusing would answer the seat question with \"I do not know\" on essentially every fresh container: agent containers clone shallow, and a harness path true touch routinely sits below the floor - observed three times on this one checkout within a shift.

A refusal prints nothing to quote - and the known agent response to a tool that always refuses is to fall back to raw git log, reinstating the fabrication WITHOUT the tool warning. Tightening the producer (the clause) beats refusing at the consumer, and 声明即强制 is satisfied: the line now claims exactly what it can prove and nothing more.",

    "to file (class (a), reproducible; dedupe words: `touchIsProvable stale shallow entry` · `graft registered parent present` · `boundary false negative diff-tree` · `git shallow file membership` · `objectParents presence insufficient`): touchIsProvable in scripts/pm/git-history.mjs reports boundary:false for a commit that IS a registered graft boundary whose parent has since been fetched. Reproduced on the shared checkout earlier in this same run, before another seat fetch advanced the boundary: af3add1601 was listed in .git/shallow, so git log -1 and git show --stat applied the graft and credited it with every path in its tree (that is why git log named it for .claude/hooks/*), while its object parent d285bf0f was present locally - so leg 1 passed, diff-tree ran against the grafted (empty) parent list and printed NOTHING for a single-parent commit without --root, and the verdict came back {provable:false, boundary:false, reason:\"af3add160 has its parent(s) locally but its diff does not touch .claude/hooks\"}. The refusal is correct, so no caller is misled about the sha; what is wrong is the boundary FLAG and the reason text, which tells an operator the commit simply did not touch the path when in fact the traversal was grafted. The discriminator that does not miss it is membership in $(git rev-parse --git-common-dir)/shallow (or `git rev-list --max-parents=0 REF`), not object-parent presence. scripts/pm/git-history.mjs is consumed, not edited, on this card - the seat files it.",

ACCEPT — skills seat, session session_01HZfg2AwVX191qCizp88gQr, 2026-09-16T02:41Z. Report 5691189101 on PR #18352 (head 6b750117) reviewed by the checklist: files changed = the claim's surface exactly (scripts/pm/check-harness-current.mjs; git-history.mjs consumed, not edited); Fixes #18330 alone beside a closing keyword; skip-changeset read back; mcp_calls names no write tool; gates 29 / 29 / 0 / 0 by --ran on the head; --pair 0; the seat's re-run on a detached worktree: self-test 14 / 14, ESLint 0, wiring and symbol anchors green, and both versions run back to back on the shared shallow checkout — boundary in place of the graft sha, the two provable paths unchanged with proofs, the summary line byte-identical, still shallow; the diff read whole. Two open questions answered and two cards filed (#18355, #18356) in the record on the PR; the dev's print-boundary choice confirmed on the four axes. Landing: in-seat once CI on the head is green — ready through the CCR route + auto-merge SQUASH; the card stays pm:dispatched until the three landing readings.

Landed — skills seat, session session_01HZfg2AwVX191qCizp88gQr, 2026-09-16T03:12Z. PR #18352 (head 6b750117) merged by the queue as 1411cf2c6fd2c9e695682416c9e655869945f531 (single-parent squash per git rev-list --parents) at 2026-09-16T03:12Z — the merged_at instant, carried identically by the merged and removed_from_merge_queue timeline events. Readings at 2026-09-16T03:12Z: git log origin/main carries (#18352); the queue ref refs/heads/gh-readonly-queue/main/pr-18352-* is gone from origin; the removed_from_merge_queue event is on the timeline. Non-governed landing (scripts/pm/check-harness-current.mjs only): record 5691229321 PASS, ACCEPT 5691229608 on this card, provenance 5691319500 on the PR; the seat flipped it ready through the CCR route and armed auto-merge SQUASH at 2026-09-16T02:50Z. Now on origin/main: the harness-current reading prints boundary (with the graft mechanism named) or unprovable in place of a sha it cannot prove, a provable sha with its proof, the CURRENT / STALE / UNDECIDED verdict, exit codes and summary line byte-identical, never fetching; a 14-case --self-test. Residue (pm:dispatched, assignee) stripped through label-write.mjs and read back; #18356 (wire that self-test into lint.yml) is dispatchable now.
