[finding] check-governed-merges.mjs silently ignores unknown flags and PM_SWEEP_REPO, so --pr N --repo objectstack-ai/objectui answers objectstack's PR N with a confident NOT governed #21675

session_01AavokzJ5DndAwitDXvKy4U· 2026-10-04T03:54Z. ⛔ Not a claim, ⛔ not a dispatch.Why p2. It is the governed-surface predicate that seats run before arming a merge. It prints a confident "NOT governed" about a different PR in a different repository. The merge-group guard is the backstop, so no governed merge slips through, but the landing act on the record is wrong.
Routing. The governed-surface audit (
scripts/pm/check-governed-merges.mjs) isdomain:skillsby the lane table.Direction: the card's second option, which adds no new spelling.
- An unrecognised flag is a usage refusal (exit 1), as
label-write.mjs,post-stamped.mjsandissue-create.mjsalready refuse. - A bare
--pr Nis refused when--repoorPM_SWEEP_REPOnames any repository other than objectstack. The refusal prescribes the documentedowner/repo#Nspelling. - ⛔ No new
--repomeaning for this tool: one spelling, the documented one. - Pins (one self-test row per refusal):
- an unknown flag is refused;

"premise_still_valid": true,
"summary": "Premise reproduced on origin/main 7d07814: rows 1-3 of the card's table (--pr 11590 --repo objectstack-ai/objectui, PM_SWEEP_REPO=objectstack-ai/objectui with --pr 11590, --pr 11590 --bogus-flag x) each read objectstack's PR 11590 (7 files) and printed a NOT governed verdict on exit 0, while row 4 (--pr objectstack-ai/objectui#11590) read objectui's 18 files. Implemented the ruling in scripts/pm/check-governed-merges.mjs only (+383/-7). Each mode now has a closed flag set (ARGV_MODES), and main() refuses any flag the running mode does not read on exit 1, naming it and printing the usage, before any git read, network read or child process. --repo is refused like any other unread flag; beside a bare --pr N the refusal prescribes --pr REPO#N. No new --repo meaning was added. runPullMode now refuses a bare --pr N when PM_SWEEP_REPO names a repository other than the one a bare number answers (this checkout's origin slug, which is objectstack-ai/objectstack wherever the tool lives), before any API read, and prescribes both qualified spellings. PM_SWEEP_REPO is read only to refuse, never to redirect the answer. A qualified --pr is answered byte-identically to before, with or without PM_SWEEP_REPO. Exit codes are unchanged (every new refusal is the existing 1). --test, --branch, the sweep and --self-test answer every argument list they accepted before. Two implementation readings are stated in the PR's Acceptance notes and are not reopened rulings. (1) The sets are per mode, because a real flag of another mode beside --pr was ignored in the same way: --pr 11590 --repos objectui read objectstack's PR, and --test src/x.ts --since 7d made 7d a path. Both were measured on the base. (2) 'objectstack' in the ruling is compared as the slug a bare number actually answers. This is identical in every run from this repo. Dispatch count note: the dispatch said 31 gate commands, but the list it pasted has 32 lines, and that list equals this worktree's own derivation exactly.",
"tests": "All readings below are at head 6854ff6 unless they name the base 7d07814. Reading 1 (real read-only GETs): before, rows 1-3 exited 0 and read /repos/objectstack-ai/objectstack/pulls/11590/files with NOT governed, and row 4 exited 0 and read objectui (18 files). After, rows 1-3 exit 1 with the refusal and the prescription --pr objectstack-ai/objectui#11590, and row 4 exits 0 with output diff-identical to before; it is also identical with PM_SWEEP_REPO=objectstack-ai/objectui set. Reading 2: node scripts/pm/check-governed-merges.mjs --self-test went from 454 assertions (31 batteries, SELF_TEST_BATTERY_FLOOR 31) to 476 assertions (32 batteries, floor 32), exit 0. The new battery 'the argv is CLOSED' registers 22 cases with floor 22. It has its own battery because it pins a different predicate from the 17003 list-derivation battery, and the roster floor was raised so that deleting the battery is caught. One row per ruled pin. The end-to-end rows run against a fake API on 127.0.0.1 (GITHUB_API_URL) that records every request; tokens are blanked, PM_SWEEP_REPO is cleared and NO_PROXY is set for loopback. Each refusal is asserted as exit 1, prescription present, no verdict, zero reads. The qualified spelling is asserted as exit 0, NOT governed, exactly 3 reads all under /repos/objectstack-ai/objectui/, and byte-identical with PM_SWEEP_REPO set. Controls cover the own-repo PM_SWEEP_REPO case, every argument list the earlier batteries spawn, and the 13 header usage examples. Ablations: fix committed first; each leg ran through node scripts/ablation-replace.mjs in wrap mode around --self-test; each anchor count went from 1 to 0, and each restore was proven as blob == HEAD 89af2f9355e2 with git diff HEAD empty, re-checked by hand after each leg. A1 disabled the unread-flag wiring in main(): exit 1, 3 red (e2e bogus-flag and e2e --repo both status=0 reading objectstack's PR 11590, plus e2e --test --since). A2 added '--repo' as a value flag of --pr: exit 1, 3 red (pure --repo prescription row, no-new-spelling row, e2e --repo status=0). A3 disabled the PM_SWEEP_REPO wiring: exit 1, 1 red (e2e PM_SWEEP_REPO status=0 reading objectstack). A4 made bareTargetRefusal over-refuse the qualified spelling: exit 1, 3 red (pure qualified row, e2e answers-as-today status=1 reads=[], byte-identical row). Gates: node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack (no path) derived 32 commands from 1 path against merge base 7d07814, the same set as the dispatch list. The 31 commands outside the lock all exited 0, each with its own pass line read (e.g. check:pm-governed-merges 476 assertions, check-scripts-symbol-anchors 3760 anchors resolve, check:entry-guard 221 export bindings inert, check-comment-mask-corpus 8140 files 0 disagree, check:nul-bytes OK). pnpm check:pm-dispatch-gates ran under os-verify-lock with OS_VERIFY_LOCK_SLOT=issue-21675-pm-dispatch-gates. The first attempt queued behind another seat's run of the same gate and exited 99 at budget (slot kept). The resumed slot acquired after 476s more: VERDICT command-exit 0, 'dispatch-gates self-test: 1976 cases pass', held the lock 1224s (20m24s) on a shared box. node scripts/pm/dispatch-gates.mjs --ran ran.list (COMMAND :: exit CODE lines) printed: 32 derived, 32 run, 0 NOT-MEASURED, 0 UNRUN. Lint, narrowed and declared as narrowed: eslint --no-inline-config --format json on the one changed file gave 1 file, 0 errors, 0 warnings. --print-config shows 2 rules apply and parserOptions are only ecmaVersion/sourceType. eslint.config.mjs has no project/projectService, so type-aware linting is off and this diff cannot change the lint result of any untouched file. Repo-wide pnpm lint is left to CI. No package build or test layer applies: the diff touches no workspace package.",

origin/maineea82af6)Before flipping objectui PR objectstack-ai/objectui#11590 ready, the seat ran the pre-arm predicate that

It also ignoresPM_SWEEP_REPO.cross-repo-coordination.mdnames exactly those two (--repoandPM_SWEEP_REPO) as the ways a tool is told which repo it answers. Its sibling tools (label-write.mjs,post-stamped.mjs,issue-create.mjs) take--repoand refuse an unknown flag as usage.Reach: which fleet decision goes wrong
The predicate is the seat's gate before
pr_ready+automerge_enableon any sister-repo PR. If objectui PR N touches a Tier H path and objectstack PR N does not, a seat that spells it with--reporeads «NOT governed» and enqueues a PR that must wait for a human approval. TheGoverned Surface Queue Guardin the merge group is the backstop, so the cost is a refused merge-group run and a wrong landing act on the record, not a silent governed merge. The same seat that hit this landed on the right answer only because the file count (7 against an 18-file PR) looked wrong.Likely landing (a lead, not a ruling)
--repo/PM_SWEEP_REPOfor a bare--pr N, or refuse a bare number when either one names a repo other than objectstack. Both close the confident-wrong answer; the second adds no new spelling.Dedupe
