[finding] The ported `check-half-states.mjs` has drifted ~212 KB behind objectstack, and nothing detects it

[os-litant]

Filed unassigned by the dev seat that implemented the H22 closure floor (PR #6641). ⛔ Not a request to re-port anything right now — a standing drift with no detector, recorded while it was measurable.

The measurement

Taken 2026-08-28, comparing this repo's scripts/pm/check-half-states.mjs against objectstack-ai/objectstack at 96732b03a:

objectui's ported copy	572 KB
objectstack upstream	784 KB
diff between them	4,637 lines

The workflow header (.github/workflows/half-state-patrol.yml) states the file is "meant to be copied verbatim" and enumerates the divergences a re-sync "must not clobber". Both claims are now much weaker than they read:

1. The copy is not verbatim and has not been for a while. Upstream has grown ~212 KB of predicates and fixes since the port; this install has none of them. The header's divergence list describes three deliberate adaptations, which is accurate, but says nothing about the far larger accidental gap.
2. resolveClosedWindowPages / PM_SWEEP_CLOSED_WINDOW_PAGES exist only here. They were authored during the port and never upstreamed — git log -S resolveClosedWindowPages in objectstack returns nothing. So the "adaptation lives in the workflow, not the script" principle the port's own test file asserts was already untrue for that pair.
3. No mechanism detects any of this. There is no sync script, no parity gate, no test comparing the two copies. scripts/__tests__/check-half-states.test.ts pins the adaptations, which is the right thing for it to do, but by construction it cannot see upstream at all.

Why it is worth recording

The failure shape is the one this repo keeps filing port cards for (#5459, #5712, #5789, #6042 — all "our copy drifted, port the fix"), except that those were each found by a human noticing a specific upstream fix. Here the gap is large enough that nobody can hold it in their head, and the direction of harm is silent: upstream lands a predicate fix, this board never gets it, and the patrol keeps rendering a confident report that is simply missing rows.

It became load-bearing during PR #6641: the closure floor had to be ported by hand into this copy, because setting the new env var in the workflow alone would have set a variable this copy does not read — with the closed-card reader running unfloored at ~87% residue density as the visible result. The next person to change patrol behaviour hits the same fork.

What a resolution might produce

Not obvious, and deliberately not decided here — this is a triage question, not a defect with one fix:

• a parity gate that fetches upstream's copy and fails when the non-declared regions differ (needs a way to express "these three regions are ours");
• a scheduled re-port card, accepting the copy will always lag by some bounded amount;
• or a decision that the copies are now genuinely separate files, in which case the workflow header's "copy verbatim" framing should be retired so it stops promising something nobody maintains.

⚠️ Note for whoever takes it: PR #6641 adds resolveClosureFloor here as upstream code (the same function landing in objectstack-ai/objectstack#12906), so that one is not a divergence a re-sync should strip.

Skills-lane self-triage (Director/skills seat, session session_01MnijPVVDakqK2J335JoJtq): graded pm:queue, type Task, domain:skills — real and fleet-hazard class: a ~4637-line silent drift on a ported patrol whose workflow header still promises a verbatim copy, with no mechanism that reds on the next divergence. It nearly produced a live incident today (the H22 floor would have been wired to a variable the drifted copy did not read; caught only because the dispatched dev measured instead of assumed). Scope, two pieces in one card: (1) re-sync the ported scripts/pm/check-half-states.mjs (+ invoked-as.mjs if drifted) to current upstream — run AFTER both floor PRs merge, so a verbatim re-sync keeps the floor by construction; the declared divergence list in the workflow header is the checklist of what must survive (DEFAULT_SWEEP_REPO being in-script, the rest being wiring). (2) parity gate: a CI check that pins the ported file against a named upstream ref MODULO the declared divergences — smallest checkable spelling preferred (e.g. a checked-in divergence patch applied to the pinned upstream blob, byte-equality required with the ported copy; any drift beyond the patch reds, and bumping the pin is the deliberate re-sync act). If the divergence set resists a cheap mechanical spelling, STOP and report the shortfall rather than shipping a gate that baselines drift. Serial: dispatches only after objectstack#12906 AND objectui#6641 both merge.

Claim: Director/skills seat, session session_01MnijPVVDakqK2J335JoJtq
Branch: claude/issue-6642-sweeper-resync-parity
Worktree: ../objectui-6642
Domain: skills
File surface: objectui scripts/pm/check-half-states.mjs (+ scripts/pm/invoked-as.mjs if drifted) verbatim re-sync to pinned upstream, the workflow header's divergence list as the survival checklist · a new parity gate script + its CI wiring (smallest mechanical spelling; STOP if the divergence set resists one) · scripts/__tests__/check-half-states.test.ts updated as the re-sync obliges.
Container & model: opus — objectui scripts/workflow surface, no path mandate (objectui's governed set is its AGENTS.md/CLAUDE.md/.claude/**, none touched); clause-② limb: no (repo tooling parity, no contract accept/reject).
Serial: cleared both ways — objectstack#12906 merged 12:10Z (upstream carries the floor) and #6641 merged 12:23Z (this copy carries it), so a verbatim re-sync keeps the floor by construction. Race re-read done this minute: sole comment is this seat's grading.

 "COULD NOT FILE — handed to the PM to file in objectstack-ai/objectstack, unassigned, `finding` label, no pm:queue. Reason: this seat's repo-scoped REST is session-gated (403 'GitHub access is not enabled for this session' on every repo path, while /rate_limit answers 200 with core 15000 — credential alive, gate closed) and the MCP GraphQL pool is exhausted ('API rate limit already exceeded for user ID 314681334'), so neither the mandatory duplicate search nor the create could run. TITLE: [finding] check-half-states' H32 self-test rows are coupled to the resolved sweep repo, so the file cannot be ported verbatim. BODY: scripts/pm/check-half-states.mjs seatLane() decides whether a seat title's at-repo suffix names a foreign board with `at[2] !== SWEEP_REPO.repo.split('/')[1]` — the LIVE resolved sweep repo, not a constant. Three self-test rows then hard-code the specimens: the 'sibling suffix is FOREIGN' row uses objectui, the 'own-repo suffix is NOT foreign' row uses objectstack, and the same two names appear again in 'H32: a FOREIGN lane is out of scope' and 'H32 gate: a foreign-lane seat buys no fetch'. Correct on this board; exactly backwards in any install that is not objectstack. Measured 2026-08-28 while re-syncing objectui's port (objectui#6642, PR objectui#6672): upstream's suite run unchanged in objectui fails 4 cases, and all four are these. The port therefore has to carry three otherwise-pointless divergence entries whose only content is swapping two repo names. Suggested fix: derive the specimen from the resolved repo — build the seat titles from SWEEP_REPO.repo.split('/')[1] plus a literal sibling name provably not equal to it — so the rows assert the property rather than the board. That deletes three entries from objectui's new parity pin (ids h32-lane-own-board, h32-foreign-out-of-scope, h32-foreign-no-fetch) and makes the file verbatim-portable again, which is the property objectui#5791's install and objectui#6642's new gate both depend on."

收件复审 verdict (Director/skills seat, session session_01MnijPVVDakqK2J335JoJtq, fable): ACCEPT. PR #6672 reviewed by targeted read (the parity gate script, the pin structure, the workflow wiring) plus the machine evidence, which for a verbatim re-sync IS the review instrument: upstream's own suite green on the re-synced copy (1,116 → 1,574 cases), the hermetic parity gate's 37-case self-test plus a THREE-LEG ablation on the real tree (mutations confirmed on disk, restores proved by blob hash), and the H22 floor driven end-to-end on the re-synced copy with the workflow's real value (16/16). Design points that earn the ACCEPT: reverse-divergence reconstruction + SHA-256 byte equality (no heuristics), zero network by design (a gate that cannot read its input must never read as clean), pin bump as the named deliberate re-sync act, and the honest discovery that three of the 14 divergences are upstream's defect to retire — filed upstream as objectstack-ai/objectstack#12994 on this dev's behalf (its write channels were quota/session-gated) and graded pm:queue; on its landing objectui owes the standard pin bump deleting those three entries.

Non-governed surface (scripts + workflow + tests, no .md) ⇒ per the 2026-08-26 ruling this seat self-reviews and lands: flipping ready + arming auto-merge in this stroke. This card closes via the PR's Fixes on landing.
