fix(spec): check:react-declaration-parity 无 MANIFEST 时报错退出,门禁台账改记「此处跑不了」(#4690) (#5959)

The gate had no path on which it could go red: it is in no workflow, and a
manual run without MANIFEST printed a warning and exited 0.

Measured first, before wiring anything: the manifest cannot be produced in this
repo. Its only producer drives a real browser at objectui's built console
(`window.__MANIFEST`); packages/console/dist/ is gitignored, build-console.sh
deliberately does not dump one, and the published @objectstack/console tarball
carries no sdui.manifest.json (16.1.0: 513 files, 0 `sdui` matches). Wiring a
lint.yml step would have wired a permanently-skipping step.

- missing / nonexistent / malformed / empty MANIFEST now exit 1 with a
  prescription naming the producer, independent of --strict (that flag prices a
  divergence; this is "no comparison happened").
- check:generated moves it from NO_GENERATOR into a new EXTERNAL_INPUT_REQUIRED
  bucket recording the missing input and its runner, whose honesty is enforced:
  reconciliation fails if gen-sdui-manifest.sh stops invoking the gate.
- Tests assert EXIT CODES: a fabricated registry-only input and a vanished block
  each exit non-zero naming themselves; an accepted state still exits 0.

+`check:react-declaration-parity` had no path on which it could go red — a missing manifest now fails instead of skipping, and the ledger says "cannot run here" instead of "deliberately not run".
+
+Two things stacked. The gate was in **no workflow** (`grep -rl check:react-declaration-parity .github/workflows/` returned nothing), and a manual run without `MANIFEST` printed `⚠ manifest unavailable … — skipping.` and **exited 0**. So the one gate whose history is written up in AGENTS.md as worth keeping — `spec-only` / `registry-only` / `missing` are real signals — could not fail for anybody, ever. Two other issues had already started citing it as the negative example of a gate that cannot be shown to catch anything (#4804 / #4777).
+
+**Where the manifest comes from, measured before anything was wired.** The right-hand side is objectui's `sdui.manifest.json`, and this repository cannot produce one: its only producer drives a real browser at objectui's built console and reads `window.__MANIFEST` (the registry pulls browser-only deps, so nothing enumerates it from Node). `packages/console/dist/` is gitignored, `scripts/build-console.sh` deliberately does not dump one — it must not drag a browser into the console build — and the published `@objectstack/console` tarball contains no `sdui.manifest.json` either (16.1.0: 513 files, zero `sdui` matches; its `dist/manifest.json` is the PWA manifest, so even the CLI's `@objectstack/console/dist/sdui.manifest.json` fallback resolves to nothing). Wiring a step into `lint.yml` would therefore have wired a **permanently skipping** step — the same defect with CI decoration.
+
+- **"Could not run" is now a failure, not a skip.** No `MANIFEST`, a path that does not exist, malformed JSON, or a dump declaring zero components each exit **1** with a prescription that names the producer (`pnpm sdui:manifest`, `OBJECTUI_ROOT=../objectui pnpm objectui:build`) and the browser it needs. Deliberately independent of `--strict`: that flag prices a *divergence*, and this is the other thing entirely — no comparison happened. The empty-dump case is new coverage in the same family; objectui's dumper already refuses to *write* one, and this refuses to *read* one instead of reporting every block as missing.
+- **The ledger stops implying someone runs it.** `check:generated` moves it out of `NO_GENERATOR` ("runnable, deliberately not run here") into a new `EXTERNAL_INPUT_REQUIRED` bucket that records the missing input and its producer, and prints `cannot run here: check:react-declaration-parity — needs MANIFEST=…; runs in scripts/gen-sdui-manifest.sh`. Following `EXPLICIT_GENERATORS` (#5358/#5807), the classification carries an enforced claim rather than a label: the reconciliation fails if `scripts/gen-sdui-manifest.sh` stops **invoking** the gate on a non-comment line — a gate filed as "runs elsewhere" while running nowhere is the exact hole this bucket exists to expose.
+- **The gate is now demonstrably able to fail.** `check-react-blocks-declaration-parity.test.ts` asserts exit codes, not just report text: a fabricated registry-only input and a vanished block each exit non-zero **naming themselves**, all four "could not run" paths exit non-zero, and an accepted state still exits 0 so the red is discriminating. The pre-existing helper swallowed exit codes by design, so every earlier test would have passed against a script that always exited 0 — which is what this gate was.
+
+Where the manifest should come from in CI (an objectui clone plus a browser in this repo's workflows, a published manifest artifact, or a Node-side dump in objectui) stays an open provenance decision, filed separately. Until it is answered, the honest state is a gate that runs at `pnpm sdui:manifest` and refuses to pretend otherwise.
