finding(scripts/pm): all three scripts/pm/*.sh are tracked 100644, so the direct invocation their own headers document returns exit 126 — and 126 is one digit from os-verify-lock's documented 99 #19044

File surface: the tracked mode ofscripts/pm/os-verify-lock.sh·scripts/pm/ensure-pm-labels.sh·scripts/pm/os-regen-merge.sh(100644 → 100755,git update-index --chmod=+x, content byte-identical), plus the measured criterion over everyscripts/**/*.sh(which files document a bare-path invocation, and their modes) in the PR body; ⛔ no new gate (shape C is a human-floor item — a note in the report, not a change), ⛔ no header rewrite unless a header documents a spelling that stays refused after the mode fix.

Thread-read: card body (os-tesla, the objectuidomain:ui#2seat, filed on the charter's rule) + triage 5731070085 (os-sam, 2026-09-18T13:59Z:priority:p2, lane skills as non-gatescripts/pm/**; the three modes re-read as 100644 with 24 tracked100755.shfiles in the repo as the contrast; the taker must re-run the direct invocation first and refute the card if it runs). The seat re-ran it at 2026-09-18T14:07Z in the shared checkout: directscripts/pm/os-verify-lock.sh --statusexit 126,bash …exit 0 — the premise holds.
Serial constraints cleared: no open PR touches anyscripts/pm/*.sh(file lists of all open PRs read at 2026-09-18T14:07Z); stem scan oforiginheads for19044/exec-bit/file-mode: none. Batch: 2 in flight (#19029, this). Lock free.
Ruling-ref: none — the scripts' own headers are the contract (class b); the A / B / C shapes on the card are the dev's to measure, with the criterion first: a header that documents a bare-path invocation ⇒ the file needs the execute bit (A); the repo already tracks 24.shfiles as 100755, so +x is the repo's convention, not an exception

What is REFUTED is the dispatch's widening of it: the 裁决 states 'the three scripts' own headers document a bare-path invocation … and the twins in the other two headers'. There are no twins. `ensure-pm-labels.sh` documents `bash scripts/pm/ensure-pm-labels.sh` (+ `--reconcile`) and `os-regen-merge.sh` documents `bash scripts/pm/os-regen-merge.sh` (+ `--self-test`) — both bash-prefixed, both exit 0 at mode 100644, measured. The card itself never quoted those two headers; it used them as MODE controls (all three are 100644 — true) and the dispatch read that as a CONTRACT reading. So the card stands, with one file in the class instead of three.", "summary": "Gave `scripts/pm/os-verify-lock.sh` the index execute bit (100644 → 100755), content byte-identical: blob id 8ad1813feff415727c4bd16f834707d20c6fc34c before and after, `git diff --summary` = one `mode change` line, 0 insertions / 0 deletions. Shape A, on one file rather than three, because the criterion the card demanded FIRST was measured before any edit and places exactly one: a bare-path invocation SITE is what needs the bit, and the repo has only two kinds — the five `.claude/settings.json` hook commands (all already 100755) and this script's own 5-line usage block plus the PM dispatch instruction at `.claude/skills/pm-dispatch/SKILL.md:438`. Every other execution site in the repo spells `bash PATH`: 17 workflow `run:` lines (including lint.yml:1698 and :1779, the self-test gates for two of these three scripts) and 9 `package.json` entries. After this PR the criterion holds with ZERO violations across all 29 tracked .sh files. Assignee was `os-elon-musk` (set by the PM) on arrival and was not touched. Shape B not taken (no header text edited); shape C not taken (no gate).", "criterion_table_summary": "29 tracked .sh on origin/main at abb01f105 — 22 at 100755, 7 at 100644; all 29 carry the shebang `#!/usr/bin/env bash`, so nothing newly executable can fall through to `sh`. Header = first 40 lines, self-path in command-word position. 9 files document a bare path (5 `.claude/hooks/*.selftest.sh`, build-console.sh, bump-objectui.sh, collect-release-notes.sh, os-verify-lock.sh) — of those, os-verify-lock.sh was the ONLY one at 100644: the single violation. The 5 non-selftest `guard-*.sh` hooks document no bare path but ARE invoked bare from `.claude/settings.json`, and all 5 are already 100755 — which is what proves the criterion is about invocation SITES, not header prose. The remaining 6 files at 100644 (ensure-pm-labels.sh, os-regen-merge.sh, the three scripts/ci/select-*.sh, publish-smoke.sh) have no bare-path site anywhere: five document `bash PATH`, publish-smoke.sh documents no usage line at all. The full 29-row table (file · mode · shebang · documents-bare-path · verdict) is in the PR body. NOTE: the triage comment's contrast figure of '24 tracked 100755 .sh' is off by two — the measured count is 22, cross-checked against `git ls-tree -r origin/main` as well as `git ls-files -s`; the PM's 22/7 reading re-measures exactly, as do the card's and the dispatch's three scripts/pm rows.", "reader_test": "A dev copies `scripts/pm/os-verify-lock.sh --status` out of the header, pastes it at a worktree root: on this branch it prints the lock state and exits 0; on origin/main it prints `Permission denied` and exits 126.

Repo-wide eslint: NOT owed and PROVEN not owed rather than skipped — `pnpm exec eslint --format json scripts/pm/os-verify-lock.sh` returns eslint's own verdict 'File ignored because no matching configuration was supplied', 0 errors, so the one changed path is outside eslint's examined population entirely; and the diff changes zero bytes (blob id identical), while eslint reads file contents, not index modes, so no untouched file's verdict can move either. No ablation and no reverse-verification applies: this diff adds no guard and no assertion, so there is nothing that could be made to fail.

Outside the derived total and left to CI, as the tool itself names them: 53 artifact-roster families, 11 declared-WIDE-population families, 14 families that apply only once a changeset path exists (this PR takes skip-changeset, so they stay inapplicable), 1 path-scheduled CI job (ci.yml Test Core shard, 5 steps that have no local invocation) and 2 families whose argv takes a value only a CI run supplies (check-shard-attestation, check-test-completeness) — those last two are NOT MEASURED locally by construction. Neither `check:doc-formula-expressions` nor `check:pm-dispatch-gates` appears in this card's derivation, so the dispatch's advice about the formula build and the foreground cap did not apply; nothing was detached and nothing was left NOT MEASURED for cap reasons.

Reason, measured before any edit: the other two scripts' headers document `bash scripts/pm/…`, not a bare path, and that documented spelling exits 0 at mode 100644 — there is no violated contract to remedy on them, and flipping them is precisely the move the card rules out in writing (「A blanket `+x` over everything would be the same unexamined move in the other direction」), scoped to one lane. The PM's own stated criterion — 'a header that documents a bare-path invocation ⇒ the file needs the execute bit' — applied to the true measurement yields exactly this one file. If the seat wants the lane-uniformity move anyway, it is `git update-index --chmod=+x scripts/pm/ensure-pm-labels.sh scripts/pm/os-regen-merge.sh` on this branch before landing; I did not make it because no reading in this repo requires it, and the PR body states the boundary so a reviewer is not guessing. Second, smaller correction: mechanism assumption 3 said `git diff --stat` would be EMPTY on a mode-only change. It is not — it prints the file with a zero-width graph plus '1 file changed, 0 insertions(+), 0 deletions(-)'. `--summary` is the line that carries the mode change, and it shows exactly one.

That is a second consumer taught the refused spelling, and this PR RESOLVES it (the spelling now runs) rather than escalating it, so no relabel is warranted from where I sit — and priority is not mine to move in any case. The victim-side condition (a report, card or PR description recording 126 as a real gate failure or as os-verify-lock's 99) was NOT measured: my dedupe radius did not include other cards' bodies or comments, and I did not scan for it. `.claude/agents/os-dev.md:103` names `os-verify-lock.sh --status` as a bare BASENAME with no directory, which would not run even with the bit set (not on PATH) — a prose naming, not a documented invocation, so I read it as outside the condition rather than a second hit.", "mcp_calls": "0 — no mcp__github__* tool was called, read or write.", "api_writes": "3 REST proxy writes, each on the first attempt: (1) POST /repos/objectstack-ai/objectstack/pulls (draft, HTTP 201, PR 19050, sent with Content-Type: application/json), (2) POST /repos/objectstack-ai/objectstack/issues/19050/labels via `node scripts/pm/label-write.mjs --repo objectstack-ai/objectstack --issue 19050 --add skip-changeset` (HTTP 200; its step-④ compare-read-back returned `size/xs`, `skip-changeset` and printed 'MATCHES the target' — `size/xs` was set by the size labeller, another actor, and was left alone), (3) POST /repos/objectstack-ai/objectstack/issues/19044/comments (this report).

The figure was used only to show that the repo DOES set execute bits, a conclusion 22 supports just as well, so the triage grade is unaffected.
