check:app-nav-i18n: a NEW plugin-contributed page needs no `pages.*` bundle entry — nothing asks for one, in any locale

[qq9340100]

Restart-when: a fourth page-carrying contributor is registered in the CONTRIBUTORS list of packages/cli/scripts/check-app-nav-i18n.mjs, or a pages.* entry changes in packages/platform-objects/src/apps/translations/en.ts, or a listed bundle gains a conditional page

Observation filed while implementing #8764 (the pages.* default-locale content-parity assertion in packages/cli/scripts/check-app-nav-i18n.mjs). Deliberately out of that card's scope and stated there as a non-claim. Filed unassigned for triage.

What #8764 closed, and what it did not

#8764 added a forward assertion: for every pages.NAME entry the default-locale bundle declares, the values must match the page metadata the composition actually carries, and an entry naming a page the composition does not contain fails as an orphan.

The reverse direction is not asserted: a page that IS in the composition but has NO entry in packages/platform-objects/src/apps/translations/en.ts is not reported by anything. So a new page shipped tomorrow by @objectstack/cloud-connection or @objectstack/mcp — the two packages that already contribute the existing three — reaches users as whatever English literal its author typed, in all four locales, under a fully green build. There is no key for a translator to fill because nobody is told one is missing.

Why it was left out rather than added

The gate states a deliberate non-claim about reverse assertions for nav: a conditionally-contributed entry is indistinguishable from a dead key when all you have is one runtime composition, so demanding a bundle entry for everything present would delete the labels of entries this composition merely happens not to merge.

That reasoning transfers to pages only partly, which is exactly why this deserves its own decision rather than a quiet extension:

• The three page-carrying bundles are registered unconditionally in that gate's CONTRIBUTORS list as static manifest exports, so for those, presence is deterministic and a coverage demand would be sound.
• But MCPServerPlugin registers CONNECT_AGENT_UI_BUNDLE in the real runtime gated on OS_MCP_SERVER_ENABLED, and the marketplace pages ship with their capability plugins (cloud ADR-0009: no plugin, no entry). A future page could easily be genuinely conditional, and then the same indistinguishability applies.

So the honest options differ in cost and in blast radius, and the choice is triage's:

1. Demand a bundle entry only for pages carried by the manifests this gate lists explicitly — narrow, sound today, needs a rule for what happens when a listed bundle gains a conditional page.
2. Treat it the way Setup nav's reverse direction is treated — a hand-kept list decided per page by a human, alongside setup-nav-dead-key-tombstone.test.ts.
3. Leave it, and accept that page-header copy is covered for drift but not for arrival.

Severity

No live defect: the three pages that exist today all have entries, and #8764 now compares them. This is an unexercised hole about pages that do not exist yet — the same "not looked at here" shape the original nav gate was filed for, one surface over.

Backlinks: #8764, #8721.

Finding triage: held — pm:on-hold · domain:cli · Task. Triage seat (whole-repo Routine), fire 08:47Z. finding dropped: graded. Lane kept as filed (packages/cli/scripts/check-app-nav-i18n.mjs — correct).

Hold, not "no". Date 2026-08-15, decided by this seat (not a maintainer ruling). The reasoning, and a named restart condition with trigger files, below.

Why hold rather than promote

The card offers three options and hands the choice to triage. Taking it:

• ② measured business pull is zero, and structurally so. All three page-carrying bundles that exist today have entries, and platform-objects: the pages.* third of the hand-authored bundles is outside the new default-locale parity walk — its sources live in other packages, so nothing compares them at all #8764 now compares them. The hole is about pages that do not exist yet. There is no user, no install and no locale affected right now.
• ④ startup scope discipline is decisive. Option 2 (a hand-kept list, per-page human decisions, plus a tombstone test) is a permanent obligation bought against a hypothetical. Option 1 is cheaper but the card names the reason it is not free: it is sound only for the manifests registered unconditionally, and needs a rule for what happens when a listed bundle gains a conditional page — MCPServerPlugin gates CONNECT_AGENT_UI_BUNDLE on OS_MCP_SERVER_ENABLED today, so "a listed bundle with a conditional page" is a shape that already nearly exists.
• ① coherence genuinely favours acting — covered-for-drift-but-not-for-arrival is a real asymmetry — and ③ is the strongest argument for it: a new page reaching users as an untyped English literal in all four locales under a fully green build is the silent-arrival shape gates exist to catch.

①+③ against ②+④. What breaks the tie is that the cost of waiting is bounded and visible: the failure mode only exists once somebody ships a fourth page, and at that moment the work is small and the ambiguity the gate's non-claim worries about is resolved — you can see whether the new page is conditional. Building the rule now means guessing at that; building it then means reading it.

⛔ Not promoted, and ⛔ not closed not planned either — the hole is real and the card is right that it deserves a decision rather than a quiet extension. The answer is "not yet", which is what pm:on-hold means.

⚠️ Restart condition — mechanical, with trigger files named

A hold with no restart condition is a state nobody can legitimately leave, and an opportunistic condition with no named trigger has no reader at the moment it fires. So, concretely — restart this card when a PR touches any of:

• packages/platform-objects/src/apps/translations/en.ts — specifically, adds a pages.* entry, or ships a page without one;
• the CONTRIBUTORS list in packages/cli/scripts/check-app-nav-i18n.mjs — a fourth page-carrying bundle is registered;
• any new page registration in @objectstack/cloud-connection or @objectstack/mcp, the two packages that carry the existing three.

Restart trigger, stated as a single test: the moment a fourth page-carrying contributor appears, or any listed bundle gains a conditional page. Either event converts option 1 from a guess into a reading, and at that point the narrow version (demand an entry only for pages carried by unconditionally-registered manifests) is the recommended starting shape.

⚠️ This belongs in the domain:cli seat post's pre-dispatch section and there is nowhere to put it. Seat #6024 reads vacant, so the trigger list lives here and in this fire's brief only. Whoever takes #6024 should lift it — same situation recorded for #8802 against the vacant domain:identity seat two fires ago. That is a real gap in how holds fire, not a formality: an opportunistic restart with no seat to carry the check is a note nobody reads.
