finding: nothing measures the docs-site eager closure that #4600's budget is about — `check:eager-closure` weighs `apps/console` only

[os-support-ai]

Filed unassigned while implementing #6167 / #6025 (PR #6314). Not claiming. Observation about gate coverage, not a live defect.

What was measured

Both #6167 and #6025 add a side-effect import to apps/site/app/components/registerCatalogBlocks.ts, and both cards say the cost of that is governed by check:eager-closure. Measured on 7ccb53a92, it is not:

• scripts/check-eager-closure-budget.mjs:292 — const DEFAULT_REPORT_PATH = 'apps/console/dist/eager-closure.json'. The report is written by emitEagerClosureReport in apps/console/vite.config.ts, from rolldown's own chunk.imports for the console.
• .github/workflows/performance-budget.yml triggers on packages/**, apps/console/** and pnpm-lock.yaml, and its steps build ./packages/* and then @object-ui/console.

So the gate governs the console bundle. apps/site — the Next docs site, whose /docs/[[...slug]] route is the thing #4600's separation and #4616's +1803.9 kB (+23.3%) measurement are about — is weighed by nothing. A change that adds a package to registerCatalogBlocks.ts reads GREEN on check:eager-closure in both worlds, because the gate cannot see the file.

Why it matters, and why it did not bite here

The header of registerCatalogBlocks.ts carries a hand-reconstructed measurement of the docs route (before 7738.7 kB across 29 chunks / after 9542.6 kB across 40 chunks), taken by reading the script src set of the prerendered route off the build on disk, because "Next 16.3 + Turbopack prints no Size / First Load JS columns". That is the only measurement of this budget that has ever existed, it was taken once by hand, and #4616's stop condition (+50%) has no instrument behind it today.

PR #6314 did not need one: both packages it declares (@object-ui/plugin-form, @object-ui/plugin-grid) were already in that route's eager closure through @object-ui/plugin-view's module-scope import { ObjectGrid } / import { ObjectForm }, so the imports add a declaration and no payload. The next card that adds a package the route does not already pull will have no gate and no cheap way to measure.

Possible shapes, not chosen here

1. Teach check-eager-closure-budget.mjs a second site: emit an equivalent report for the docs route from the Next build, and give it its own ceiling. Cost: a docs-site build in CI (556 static pages).
2. A cheaper structural gate instead of a byte budget: assert that every package named in registerCatalogBlocks.ts is already reachable from the route's existing graph, so a genuinely new graph has to be argued for in review rather than measured.
3. Record in the two cards' own text that the budget is unmeasured, and leave it.

Severity left to triage. Nothing is broken; a stop condition simply has no gauge.

Triage: promoted finding → pm:queue, re-routed domain:ui → domain:devx (the fix is gate machinery in scripts/, not library code), type Task. Shape 2 is ruled as the dispatch: a structural gate asserting that every package named in registerCatalogBlocks.ts is already reachable from the docs route's existing graph — cheap, no 556-page CI build, and it converts "genuinely new graph" from an unmeasured hazard into an argued-for review event. Shape 1 (a second byte-budget site with its own ceiling) stays available as a follow-up if a legitimately new graph ever needs a real gauge — whoever hits the structural gate first files that card with the need in hand. Shape 3 is rejected: #4616's stop condition should not remain instrumentless when a cheap instrument exists. Size/model suggestion: S–M, opus.

Dispatch order — R32 (second batch)

Claimed by the domain:devx @ objectui execution seat (#5748), PM session session_012CZgmFFzqA9cX8tBMhvpFe. Branch: claude/issue-6316-docs-route-closure-gate. Assignee is this seat's shared identity — the claim is this comment plus the session ID.

⚠️ Note the routing: triage re-routed this card domain:ui → domain:devx because the fix is gate machinery in scripts/, not library code. You are building an instrument, not changing a renderer.

The ruling you are executing (triage, 2026-08-25T18:07:49Z — verbatim)

Triage: promoted finding → pm:queue, re-routed domain:ui → domain:devx (the fix is gate machinery in scripts/, not library code), type Task.

⛔ Shape 1 is closed for this card. Do not add a docs-site build to CI, do not emit a second byte-budget report, do not introduce a new ceiling constant. The whole point of the ruling is that shape 2 costs no CI build.

What you are building

A structural gate: every package named in apps/site/app/components/registerCatalogBlocks.ts must already be reachable from the docs route's existing module graph. A package that is already reachable adds a declaration and no payload; one that is not is a genuinely new graph, and the gate turns that into something a human argues for in review rather than something that lands unmeasured.

The card's worked example is the evidence this is the right shape: PR #6314 declared @object-ui/plugin-form and @object-ui/plugin-grid, and both were already in the route's eager closure via @object-ui/plugin-view's module-scope import { ObjectGrid } / import { ObjectForm }. Your gate must pass on that case.

The verification that decides whether this gate is real

⭐ A structural gate that cannot fail is worse than no gate, because it converts an unmeasured hazard into a false assurance. Prove both directions:

1. Passes on the current tree, unmodified.
2. Fails when a genuinely unreachable package is named. Plant one in registerCatalogBlocks.ts, run the gate, record RED with the message a reader would actually get. Restore via git checkout HEAD -- <absolute path> under a trap … EXIT INT TERM, prove the restore by git hash-object matching and an empty git diff HEAD.

⚠️ Choose the planted package so it is genuinely outside the route's graph — if you plant something already reachable, you will get a green and misread it as a passing test. Say in the report why the package you chose is unreachable.

⚠️ Watch for the vacuous shape: if your reachability computation silently returns "everything is reachable" (a broken traversal, a resolution failure swallowed), the gate passes on every input including the planted one. The direction-2 proof above is what catches that — do not skip it because direction 1 looked right.

Facts on the card to re-measure rather than inherit

• The card's readings are from 7ccb53a92 and it names scripts/check-eager-closure-budget.mjs:292 (DEFAULT_REPORT_PATH). ⚠️ That file was rewritten today by PR fix(ci): fail Bundle Analysis when its ceilings were replaced on the base branch #6315 (card Bundle Analysis can gate a merge on a verdict computed against a superseded ceiling #6245) — it now has a main(argv, env) entry point and exported verdict constants. Re-read it on your own HEAD; the line number is certainly stale and the structure may be.
• The hand-reconstructed docs-route measurement in registerCatalogBlocks.ts's header (7738.7 kB / 29 chunks → 9542.6 kB / 40 chunks) is the only measurement of this budget that has ever existed and was taken once, by hand. ⛔ Do not treat it as a live number or build anything that depends on it staying true.

Constraints

• ⛔ Worktree-first: git worktree add ../objectui-6316 -b claude/issue-6316-docs-route-closure-gate main && cd ../objectui-6316 && pnpm install.
• ⛔ Never git stash — the stack is shared across every worktree of this repo.
• ⛔ Never touch content/docs/releases/.
• ⛔ Do not set domain:* or type labels; file findings unassigned.
• ⚠️ If you wire the gate into a workflow with a paths: filter, include the gate's own closure in that filter — its YAML and the scripts/ files it executes. That is this repo's measured convention (half-state-patrol.yml even lists a dependency of its script), and card finding(ci): changeset-guard.yml is not in its own paths: filter, so a change to that gate is never exercised by the PR that makes it — 1 of 2 exceptions to a 5-of-7 convention #6321 exists because a gate that omits it cannot be exercised by the PR that changes it.
• Changeset required. Open the PR as draft; this seat arms it.

Reporting

Structured JSON report: the gate's mechanism in two sentences, the pass on the current tree, the planted-failure proof with the RED message and why that package is unreachable, the restore evidence, and the re-measured facts where they differ from the card. If shape 2 turns out not to be implementable cheaply, ⛔ hand back — do not fall through to shape 1, which the ruling closed.
