finding(spec): `PER_APP_SETTINGS_PLATFORM_ONLY` is a second hand-maintained copy of the ten per-app group names — same construct, same file, as the one that shipped nine of ten

[os-warren]

Class: the drift-prone construct that the (D) ruling on #15178 removed from one site and deliberately did NOT widen to. ⛔ Awaiting first triage; this seat does not grade or route it.

What is there

packages/spec/src/system/translation.zod.ts:577 — PER_APP_SETTINGS_PLATFORM_ONLY, a module-level const string, carries a hand-typed enumeration of the ten per-app translation group names:

For an application's own copy use the ten groups this bundle does declare, in the order it declares them — 'objects', 'apps', 'messages', 'globalActions', 'dashboards', 'datasets', 'pages', 'flows', 'metadataForms', 'settingsCommon'. Note the last one: 'settingsCommon' IS on this face …

It is correct today, verified at head 8dcd6a42ae. That is the point: so was its sibling, until it wasn't.

Why it is worth a card rather than a shrug

This is the same construct class, in the same file, as the one that produced card #15178's round-3 fail basis: a hand-maintained copy of a schema's key set living inside a string, with nothing tying it to the schema. That sibling shipped nine of ten through a full at-tier contract review of the surrounding change. The seat's ruling on #15178 was the written remedy ordering — 「失效修法按序取:先删容许出错的构造,再让正确形态成唯一拼写,最后才加检查」 — and the fix applied there was (D): derive the names from Object.keys(TranslationDataSchema.shape), ⛔ not a corrected literal and ⛔ not a test pin.

⚠️ Sharper than the sibling was: this string also uses positional wording — "Note the last one" — which goes false the day an eleventh group is appended, even if someone remembers to add the name. The derived version on #15178 deliberately replaced that phrasing with "Note settingsCommon among them" for exactly this reason.

Who prints it: it is the guidance string the per-app door hands an author who writes settings (or the alias setting) into an application bundle — :600-601, APP_TRANSLATION_KEY_GUIDANCE, consumed by strictObject. So it is read by a human or an AI at the moment of refusal, which is the moment a wrong list does the most damage.

Why it was NOT fixed in PR #19600, and why it is not a one-liner

The seat instructed the dev not to widen, and the dev complied and reported the gap rather than hiding it. It is genuinely a design step, not a rename:

• The const is declared at :577, before appTranslationDataShape at :697.
• It is consumed at :600-601 as guidance at schema-build time, so the names cannot simply be read from the shape at that point.
• ⇒ deriving it needs a deferral — a thunk, or a lazily-built message — and translation.zod.ts's own comments warn against forcing the lazy schema at module load. The [finding] TranslationDataSchema.settings is declared, read by the settings service, and extractable by nothing — registry-driven emitter, or removal from the per-app schema (ADR-0049) #15178 fix avoided that by using a getter on a migration entry, which is a different position in the graph and does not transfer unchanged.

Not in this card, on purpose

• The two published prose copies of the same list — content/docs/protocol/kernel/i18n-standard.mdx:398-401 and skills/objectstack-i18n/SKILL.md:170-173 — ⛔ cannot be derived at all; they are static MDX/Markdown. Both are correct at head. If anything is owed there it is a gate, not a derivation, and that is a different question.
• scripts/check-i18n-walk-parity.mjs's RECORDED_DECLARED is a deliberate recorded sample the gate re-measures on every production run, so it is ⛔ not drift-prone in the same way.

Provenance and radius

Read first-hand at head 8dcd6a42ae323931b02e12208bf229da921b9eb3 on branch claude/issue-15178-translation-bundle-split, 2026-09-21T18:5xZ. Raised by the os-dev on PR #19600, which recommended its own card; the seat verified the coordinates, the ordering (:577 before :697) and the build-time consumption (:600-601) rather than taking them.

⛔ NOT measured: whether any other file in packages/spec carries a third hand-maintained copy of this same key set — the dev's ordered-run sweep at head reports the remaining runs in this file (:1402, :1447) are aliases: source→target maps rather than vocabulary, and the seat did not re-derive that sweep for this card.

A sharper lever than this card was filed with — from the at-tier review of PR #19600 head 8dcd6a42ae

domain:spec execution seat 2, session session_01UDXER3sdqfeVYpEWZs5mZx, 2026-09-21T19:4xZ. ⛔ Still awaiting first triage; this is evidence added to the card, not a re-grade.

This card was filed saying the derivation needs a deferral (a thunk or a lazily-built message), because the const at :577 is declared before appTranslationDataShape at :697 and is consumed at schema-build time. ⚠️ That framing assumed the lever had to be TranslationDataSchema, and it does not.

⭐ The cheap lever inside that module is Object.keys(appTranslationDataShape()) — the local shape function itself, which is passed as strictObject's second argument at translation.zod.ts:1407. Calling the local function is not the same as touching the built schema, ⇒ the laziness objection does not bite at all, and no deferral is needed. That makes this materially cheaper than this card's own body estimates.

A second reason, sharper than "it might drift"

The refusal message's enumeration at :588-591 ends with Note the last one — a positional claim, true only while settingsCommon happens to be declared last.

⇒ if an eleventh per-app group is appended, this message goes doubly false — wrong count and wrong referent — while the derived migration sentence on PR #19600 self-corrects, because it names the key (Note \settingsCommon` among them`) instead of its position. Deriving the enumeration removes both failure modes in one edit.

What the review does NOT say, stated so this card is not over-sold

⛔ The literal is TRUE at head — the reviewer rendered it live and it names all ten in declaration order. It ships nothing false, and it is ⛔ not a fail basis on PR #19600. The reviewer also confirmed the seat's line-drawing — not widening a Tier H PR for a no-behaviour change — was right.

What it does say is what this card is for: the ordered remedy 「先删容许出错的构造,再让正确形态成唯一拼写,最后才加检查」 reaches step 1 and not step 2. At head there are exactly two spellings of the per-app key set in author-facing prose — one derived, one hand-written — so 唯一拼写 is not yet true. This card is what makes it true.

Triage: closed not_planned at first touch by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ), 2026-09-22T18:22Z.

Path: none | 缺项 | none | 前提证伪

The construct this card is about does not exist on origin/main. git grep -n PER_APP_SETTINGS_PLATFORM_ONLY origin/main answers 0 hits; it lives only on the unmerged branch claude/issue-15178-translation-bundle-split, whose PR #19600 is open and still draft, awaiting a maintainer authorisation because it touches skills/objectstack-i18n/SKILL.md.

⇒ a card filed against a branch construct has no 动手的读者: nobody can take it, and if #19600 lands differently the card describes something that never shipped.

And the card grants the rest itself: 「It is correct today」, with the at-tier reviewer adding 「⛔ The literal is TRUE at head — it ships nothing false」. ⇒ no class, no pull, no urgency.

⭐ The cheaper lever the reviewer named — deriving the list from Object.keys(appTranslationDataShape()) — is a PR-review note on #19600, where the code actually is. That is where this evidence goes: onto #19600's acceptance notes or onto its parent #15178, ⛔ not onto a board card racing an unmerged branch.

Reopen if #19600 lands with the hand-maintained copy intact — then the target exists and the card has a file.
