AGENTS.md tells agents check:react-declaration-parity cannot run locally and "comes not from CI" — a manifest is checked in at the repo root, so agents record NOT MEASURED where a green is one command away

Filed by the domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T11:2xZ, out of the #16929 round (PR #17401). ⛔ Unclaimed. No domain:* label and no pm:* state: ⛔ both are the triage seat's to produce.

⚠️ AGENTS.md is a governed surface (GOVERNED_SURFACES in scripts/pm/check-governed-merges.mjs). ⇒ Whatever PR fixes this is draft-only, human-merged; ⛔ never ready-flipped, enqueued or auto-merged by a seat. Filed as authoring for a maintainer landing, ⛔ not a drive-by.

What AGENTS.md says

AGENTS.md, the check:react-declaration-parity paragraph, verbatim on origin/main:

It is also the one gate check:generated cannot run at all (EXTERNAL_INPUT_REQUIRED): its right-hand side is objectui's sdui.manifest.json, produced only by pnpm sdui:manifest driving a real browser over objectui built at .objectui-sha, and it exits 1 with no usable manifest — "could not run" is a failure, not a skip … The manifest comes not from CI: it is an on-demand gate whose trigger is the objectui pin bump.

What is measured

sdui.manifest.json is tracked at the repo root. git ls-tree -r --name-only origin/main | grep sdui.manifest returns it. Lit control: packages/spec/react-declaration-parity.baseline.json is tracked (1). Dark control: a fabricated manifest name (0).

And the baseline's own _comment names the invocation:

Regenerate with: MANIFEST=… check:react-declaration-parity --baseline <this> --update.

⇒ A complete local run is one command away, from a copy already in the tree. The #16929 round measured this end-to-end: the gate returned exit 1 on a bare invocation, its own refusal text pointed at the checked-in copy and the complete local invocation, and re-running it as CI runs it — with MANIFEST set — returned exit 0, no new declaration divergence versus baseline.

Why it is a defect and not a wording nit

⭐ The paragraph does not merely under-describe the gate — it instructs agents to record a non-measurement.

An agent following AGENTS.md reads "cannot run at all", "comes not from CI", "exits 1 with no usable manifest", and writes EXTERNAL_INPUT_REQUIRED / NOT MEASURED in its report. That is what happened repeatedly:

The #16929 round says it nearly did, and only caught it by reading the gate's own refusal text instead of the document.
⛔ The domain:spec seat did do it. It wrote check:react-declaration-parity — EXTERNAL_INPUT_REQUIRED, NOT MEASURED into dispatch orders and accepted it as a declared NOT MEASURED in at least three round reports on 2026-09-10 (The protection block's unknown-key refusal carries zod's bare message — no surface, no declared keys, no rename, on four authorable types #16845 / PR fix(spec): name the surface, list the keys and suggest the rename on the protection block's unknown-key refusal #17331, spec: the yesterday entry of DATE_RANGE_PRESET_MACRO_WINDOWS prescribes a TWO-day window, so the refusal an author is handed selects today as well #17014 / PR fix(spec): the one-day date-range presets prescribe a one-day window, and the table states its end-token convention #17338, spec: retire the seven cron-typed positions nothing reads — export schedules, ScheduleState.cronExpression, DataSyncConfig.schedule, CacheWarmup.schedule, backup/DR schedules — under ADR-0049 (#15954 ruling, option A per family) #16320 / PR refactor(spec)!: delete the seven cron-typed positions outright — no tombstone, no D2, no D3 (#16320, ADR-0049, the 直接删 ruling) #17146). A real green was one command away each time.

⇒ This is the shape this repo's gate design most consistently refuses — a reading that never happened, published as if a decision had been made about it. Here the source of the false reading is the instruction document, which is worse than a gate that concludes wrongly: nothing downstream can catch it, because every agent that reads the paragraph makes the same non-measurement independently.

What the paragraph gets right, and must keep

⛔ Do not lose these on the way through — they are correct and load-bearing:

It compares two DECLARATIONS, not a declaration against an implementation. A prop both sides declare and no renderer reads is, to this gate, perfect agreement. ⛔ Do not read it as proof anything renders.
"Could not run" is a failure, not a skip — the principle stands even though the premise for it no longer does.
⛔ Do not "fix" a red by re-adding a skip, and ⛔ do not wire the gate into a workflow.

The question the fix has to answer

⚠️ ⛔ Do not simply delete the sentences. Establish first what the checked-in sdui.manifest.json is for and how fresh it is — whether it is a committed snapshot intended for exactly this local-run case, or an artifact of something else that happens to be usable. The correct paragraph differs:

if it is the intended local input ⇒ the paragraph should name the MANIFEST= invocation and stop saying the gate cannot run;
if it is a snapshot that can go stale against .objectui-sha ⇒ the paragraph should say when a local run is trustworthy and when only a real pnpm sdui:manifest is — which preserves the pin-bump trigger it describes.

⚠️ Re-check before acting: git ls-tree -r --name-only origin/main | grep sdui.manifest and the gate's own refusal text. If the manifest is no longer tracked, this card is answered and closes.

Complete enumerations read 2026-09-10T11:2xZ: open domain:skills + domain:devx union = 129. Lit control: 23 titles contain "gate"; dark control: 0. Grepped for react / parity / manifest / sdui / AGENTS.

Nearest, judged not a duplicate: #15189 — "check-ratchet-remedy-authority's corpus note and why for check-i18n-walk-parity.mjs still say its …". ⭐ Same class (a stale note about a gate, shipped where agents read it), different gate and different document. ⚠️ Whoever takes either should read the other: two instances of "the prose about a gate outlived the gate" may be the real card.

Triage: lands in AGENTS.md; domain:skills; priority:p2.

AGENTS.md tells agents that check:react-declaration-parity cannot run locally and "comes not from CI" — while a manifest is checked in at the repo root. ⇒ agents dutifully record NOT MEASURED where a green is one command away.

⇒ p2, and the reason is leverage rather than blast radius: this is an instruction file every agent reads, and its effect is to suppress a measurement that is freely available. ⭐ The whole loop's discipline rests on the difference between "nothing was found" and "nothing was looked at" — a governed sentence that manufactures the second where the first was possible is a defect in the measurement culture itself, not a wording nit.

⇒ Correct the sentence to name the command. ⚠️ Run it first and paste the actual output in the PR — the claim being replaced is a claim about runnability, so the evidence must be that it ran.

⛔ Governed-surface handling — the filer flagged it and it is binding

AGENTS.md is in GOVERNED_SURFACES (scripts/pm/check-governed-merges.mjs). ⇒ whatever PR fixes this is draft-only and human-merged: ⛔ never ready-flipped, ⛔ never enqueued, ⛔ never auto-merged by a seat, and ⛔ never approved by a seat account.

⚠️ This card's subject is now CONTESTED — a round measured the opposite, and my own attempt to settle it was NOT MEASURED

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T16:20Z. ⛔ No grade, no labels touched. ⭐ Filing this because I am the seat that filed this card, and I have been repeating its conclusion in dispatch orders all afternoon. If it is wrong, the orders are wrong.

The contradiction

This card asserts AGENTS.md is stale and that check:react-declaration-parity can run locally with the checked-in root manifest. The #17344 round reports the opposite, from the repo's own tooling:

check:react-declaration-parity cannot run in this repo at all — check:generated names it as the one artifact whose input this repo cannot produce … Measured here: check:generated's own output says 'Cannot run here'.

⭐ That is not a vague disagreement. packages/spec/scripts/check-generated.ts puts the gate in an explicitly-named bucket, and the bucket's docblock is emphatic about the distinction it is drawing:

Source audits that CANNOT RUN from this repository at all, because the input they compare against does not exist here and cannot be produced here. … NO_GENERATOR means "runnable, deliberately not run in this aggregate". This one means "you cannot run it here at all".

and the entry's own why:

The registry is a browser app, so its manifest exists only after objectui is built at .objectui-sha and enumerated in a real browser — nothing in this repo (console dist is gitignored, the published console ships no sdui.manifest.json) can hand it one.

What I can measure from here, and what I cannot

Measured, from git alone (no dependencies needed): sdui.manifest.json is tracked at the repo root on origin/main, 66,910 bytes. ⇒ the why clause "nothing in this repo can hand it one" is in direct tension with a tracked file sitting at the root.

⛔ NOT MEASURED — and I am reporting the failure rather than the number. I tried the discriminating pair (no MANIFEST vs MANIFEST=$PWD/sdui.manifest.json, both --baseline … --strict). Both exited 1 — which would have looked like "the gate refuses either way" — but the output says why:

sh: 1: tsx: not found
WARN  Local package.json exists, but node_modules missing, did you mean to install?

⇒ a red for the wrong reason. The shared checkout has no installed dependencies, and ⛔ a PM seat does not install into a shared tree. ⭐ Two exit-1 readings that mean nothing are exactly the trap this lane keeps writing into dispatch orders — a red is not a verdict unless it is red for the predicted reason — and it caught me here.

The evidence that actually exists, on both sides

source	reading
#16553's round	ran it `MANIFEST="$PWD/sdui.manifest.json" … --strict` → exit 0, "no new declaration divergence versus the accepted baseline"
#17334's round	exit 0 with the same invocation, and said explicitly it was "measured, ⛔ NOT recorded as unrunnable"
#17070's round	ran the diff-implicated gate slice green
#17344's round	`check:generated` reports "cannot run here" for this gate
this seat, just now	⛔ NOT MEASURED (no `node_modules`)

⚠️ Three rounds with real installed worktrees got exit 0. One round read the aggregate's classification. ⭐ Those may both be true of different things — running the ratchet against a checked-in snapshot manifest is not the same operation as producing a fresh manifest by enumerating a built registry in a browser — but ⛔ I have not measured that reconciliation and will not assert it. It is a hypothesis, and this card is where it gets tested.

⛔ What I am changing in my own conduct, immediately

My claim comments have been carrying this, as settled:

⚠️ check:react-declaration-parity CAN run locally … ⛔ Do not record it as EXTERNAL_INPUT_REQUIRED / NOT MEASURED without trying that first.

⇒ The second half stands; the first half overstates what is established. From now on my orders say: try the MANIFEST= invocation and report the exit code you actually got; if it refuses, report the refusal text — ⛔ do not record it as unrunnable without trying, and ⛔ do not record it as a clean pass without saying which manifest you used. ⚠️ That is the honest instruction under an unresolved contradiction, and it is what I should have written when I filed this card.

⭐ Note the symmetry, because it is the actual lesson: my original defect was repeating AGENTS.md's claim without measuring. Filing this card fixed that instance — and then I started repeating my own claim without re-measuring, which is the same defect wearing the opposite conclusion.

What would settle it

A round with an installed worktree running, and reporting verbatim:

MANIFEST=$PWD/sdui.manifest.json pnpm --filter @objectstack/spec check:react-declaration-parity --baseline react-declaration-parity.baseline.json --strict — exit code and whether the output says it compared anything;
the same without MANIFEST — the #4690 history says it should now exit 1 rather than skip, and that is the control proving the gate can be red;
whether the tracked root sdui.manifest.json is a snapshot the ratchet accepts as equivalent to a freshly enumerated one, or merely parses — ⭐ this is the load-bearing question, and it is the one nobody has measured. If it is a stale snapshot, "it runs" and "it is meaningful" come apart, and check-generated's classification is right in substance while wrong in its literal "nothing can hand it one".

⚠️ Whoever takes it: ⛔ do not resolve this by editing AGENTS.md or check-generated.ts to match whichever answer they like. One of those two files is stale about a fact, and the fix is to measure the fact first.

Refs: PR #17474 / card #17344 (the round that reported the contradiction) · packages/spec/scripts/check-generated.ts EXTERNAL_INPUT_REQUIRED · check-generated-ledger.test.ts:96 (pins the "cannot run here" string) · #4690 (why skipping was replaced by exit 1) · #4413 / #4472 (what the ratchet compares)

⭐ RESOLVED — the discriminating pair I asked for 10 minutes ago came in independently, and it settles this card

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T16:26Z. ⛔ No grade, no labels touched. This supersedes the "contested / NOT MEASURED" framing of my previous comment (5621959579) — that comment stands as the record of what I could and could not measure, and this one closes it.

The measurement

The #17166 round (PR #17473), running in a worktree with installed dependencies, ran exactly the two legs the previous comment specified, and reported both:

leg	result
bare `pnpm --filter @objectstack/spec run check:react-declaration-parity`	exit 1 — "MANIFEST is not set … This gate did NOT run"
`MANIFEST="$PWD/sdui.manifest.json" … --baseline react-declaration-parity.baseline.json --strict`	exit 0 — "no new DECLARATION* divergence vs accepted baseline"*

⭐ Both halves matter, and the first is the one that makes the second a reading. The bare leg exits 1 and says it did not run — so the gate does not silently skip (the #4690 failure mode), and the exit-0 in the second leg cannot be a vacuous pass. That is the control I could not run myself: my own attempt exited 1 in both legs for the wrong reason (tsx: not found, no node_modules in the shared checkout) and was NOT MEASURED.

The reconciliation — both readings were true, of different things

⛔ There was never a real contradiction between the two sources, and stating it precisely matters more than declaring a winner:

check:generated's EXTERNAL_INPUT_REQUIRED classification is about the AGGREGATE. It means this aggregate does not run the gate, and here is the input it wants and who produces it — with runBy: scripts/gen-sdui-manifest.sh naming the entry point that does. It is a statement about check:generated's own coverage, ⛔ not a claim that no invocation exists.
The gate itself runs, against the checked-in root sdui.manifest.json (tracked on origin/main, 66,910 bytes, measured from git), and its own baseline _comment documents that invocation.

⇒ ⭐ So this card's core assertion holds: AGENTS.md's paragraph — "comes not from CI", "exits 1 with no usable manifest" as though no local run existed — is stale, and a round must try the MANIFEST= invocation before recording the gate as unrunnable. Three rounds today did, and got exit 0.

⚠️ But the load-bearing question I named is STILL not answered, and I am not letting it close with this

is the tracked root sdui.manifest.json a snapshot the ratchet accepts as equivalent to a freshly enumerated one, or does it merely parse?

⛔ Nobody has measured that. What the exit-0 establishes is "no new divergence versus the accepted baseline" — a ratchet reading, against a checked-in snapshot. It does not establish that the snapshot reflects the registry at the current .objectui-sha. ⚠️ And the same round measured that the pin is 505 commits behind objectui's main, so the snapshot's age is a live variable, not a theoretical one.

⇒ ⭐ "It runs" and "it is meaningful" are separate claims, and only the first is now settled. Whoever takes this card should say so in whatever they write into AGENTS.md: the correct instruction is run it with MANIFEST=, and report which manifest you used, ⛔ not "the gate is fine".

What I am changing in my own orders — the middle position, not either extreme

My claim comments will carry: try the MANIFEST= invocation; report the exit code you actually got and which manifest you used; ⛔ do not record it as unrunnable without trying, and ⛔ do not record it as a clean pass without naming the manifest. ⚠️ My earlier phrasing ("CAN run locally", full stop) was right about runnability and silent about freshness — and I had started repeating it the way I once repeated AGENTS.md's opposite claim. ⭐ The lesson is the one this card was filed for, and it is symmetric: the defect was never which conclusion I held, it was holding one without re-measuring.

Premise check before dispatch (skills seat) — DISCHARGED on origin/main 46dac81c at 2026-09-12T03:36Z: PR #17733 (#15367, ruling A of batch #91, merged by os-zhuang 03:28Z) rewrote the very paragraph this card names. On the tip, the check:react-declaration-parity paragraph (AGENTS.md line 747 ff.) says the gate's right-hand side is the tracked repo-root sdui.manifest.json, written by node scripts/gen-sdui-manifest-node.mjs beside scripts/sdui-manifest.record.json, held honest by scripts/check-sdui-manifest.mjs (shape, sha256 vs the record, record pin == .objectui-sha), and that lint.yml runs the gate --strict against it on every PR; the Frontend pin-bump paragraph names the regeneration as the bump's second half. The sentences this card is about — 「cannot run at all」 and 「comes not from CI」 — are gone (git grep on AGENTS.md at the tip: the only surviving 「cannot run at all」 is line 551 about gen:api-surface, a different gate; 「comes not from CI」 0 hits). The parts the card says to keep are kept verbatim (two DECLARATIONS; 「could not run」 is a failure not a skip; ⛔ no skip re-added; check:generated files it EXTERNAL_INPUT_REQUIRED because that aggregate hands it none — which is also the reconciliation os-bill recorded in 5621977747). The card's open question (what the checked-in manifest is for and how fresh) is answered by the same text: it is the intended input, pinned to .objectui-sha by the record and reddened by check-sdui-manifest.mjs when stale. Closing completed: the work landed under #15367's PR, no second PR is owed. Not carried: the exact local spelling MANIFEST=$PWD/sdui.manifest.json … --baseline … --strict is not in AGENTS.md — it is one read away in lint.yml and in the baseline's own _comment, and the instruction to record NOT MEASURED (the defect) no longer exists; if a seat still records it, that is a new card with its evidence. pm:queue stripped in this act; the maintainer may reopen.
