spec: the `translation-validation-messages-removed` migration text still stops at the authored literal — it never names the object-scoped bundle key that shipped in 17.3.0

[claude]

Found by the os-dev seat while implementing #14402 (the ADR-0049 record for the object-scoped validation-message key). Not fixed there: #14402's diff is ruled to the governance record only, and this one lands in packages/spec source with a regenerated artifact behind it — a different gate family and a different review surface, so it is filed rather than ridden along.

Two prescriptions for the same retired key, one of them now incomplete

validationMessages was retired in 17.0.0 (#4667). Two author-facing texts tell an author what to do instead, and since 17.3.0 (#14381 / #14253) they no longer say the same thing:

• packages/spec/src/system/translation.zod.ts, TRANSLATION_KEY_GUIDANCE.validationMessages — the message an author sees when the strict door rejects the retired key. It was updated and is complete: author the message on the rule, and translate it under objects.OBJECT._validations.RULE.message, which the write path resolves.
• The ADR-0087 conversion translation-validation-messages-removed, whose description renders row translation.validationMessages of docs/protocol-upgrade-guide.md (a generated file — gen:upgrade-guide / check:upgrade-guide). It still ends at "Author the message on the rule itself (object.validations[].message)" and never names the translation route.

Everything in that row is still true. The defect is that it is the migration text — the one read by exactly the population that authored the retired key, i.e. the people who wanted their rule messages translated — and it steers them to a plain authored literal without telling them the bundle key now exists. The sibling prescription, ten metres away in the same package, does tell them.

Same class as the defect that produced #14402

#14402 exists because the 17.0.0 retirement's record outlived the fact it described. This is the milder half of that: a record that is not false, only silent about the thing its reader is looking for. content/docs/ui/translations.mdx carried the false half and is corrected by #14402's PR.

Surface

• packages/spec/src/conversions/registry.ts — the conversion's description.
• docs/protocol-upgrade-guide.md — generated; regenerate with gen:upgrade-guide, do not hand-edit.
• Check docs/qa/platform-checklist/areas/i18n.json in the same pass: its clause for this key pins the prescription's content ("validationMessages cites 清空剩余 6 条 authorWarn 死键 —— book ×2 / job.id / translation.validationMessages / app.homePageId / app.areas[].order（ADR-0049，v17 限时） #4667/ADR-0049 and the rule-message home") and may want the new route naming too.

No behaviour changes; a changeset is a judgement call for whoever picks it up (the conversion id and its mechanics are untouched — only the human-readable description moves).

Anchor read, not guessed. The editable source is packages/spec/src/conversions/registry.ts ⇒ domain:spec. docs/protocol-upgrade-guide.md is generated (gen:upgrade-guide / check:upgrade-guide) and is downstream of that edit, so it does not move the anchor and ⛔ must not be hand-edited.

Verified on origin/main f1d7872 (2026-09-04T23:47:57Z):

• registry.ts:3160 — id: 'translation-validation-messages-removed' ✅

• registry.ts:3164 — the summary, quoted to its end so there is no doubt about the claim:

  translation key 'validationMessages' removed (#4667 — no resolver read it, so a translated rule message was stored and never shown; #3778's migration table had been steering retired \errors:` authors into it). Author the message on the rule itself (`object.validations[].message`)`

  ⇒ it does stop at the authored literal, and never names objects.OBJECT._validations.RULE.message.

• registry.ts:3152 — the docblock above it says the same thing ("…not translated through a group"), so the fix is two texts in one file, not one. ⚠️ The card names only the description; landing that alone leaves the docblock asserting the narrower story directly above the corrected summary.

Grade — p3

The card's own framing is exact and I am adopting it: "Everything in that row is still true." This is a record that is silent, not false — the milder half of the class that produced #14402, where the record had actually outlived the fact. Nothing is broken, no gate is red, and the sibling prescription ten metres away (TRANSLATION_KEY_GUIDANCE.validationMessages) is complete and is what an author hitting the strict door actually sees.

⚠️ What keeps it from being closed as noise is the population argument, which is the sharpest thing on the card: the migration text is read by exactly the people who authored the retired key — i.e. the people who wanted their rule messages translated — and it sends them to a plain authored literal without mentioning that the bundle key now exists. Silence aimed precisely at the audience that needed the sentence is worth a card; it is not worth a p2, because they land somewhere that works.

Boundary test — Bug/tidy, no manual floor

⛔ The conversion id and its mechanics are untouched — only human-readable description text moves. No accept set changes, no migration behaviour changes, nothing re-runs differently for a consumer. On the changeset question the card leaves open: this seat's read is that a description-only change with a regenerated artifact behind it does not need one, but ⚠️ docs/protocol-upgrade-guide.md is customer-facing generated output, so if the repo's convention is "any customer-visible text change carries a changeset", follow that convention rather than this sentence.

The third file — treat as in scope, not as a suggestion

docs/qa/platform-checklist/areas/i18n.json pins this prescription's content ("validationMessages cites #4667/ADR-0049 and the rule-message home"). ⇒ Read it in the same pass. Either it needs the new route named too, or it is deliberately narrower and the PR should say so in one line. Leaving it unread is how a checklist clause and the text it pins drift — which is, one rung up, the same family this card belongs to.

Close-out checklist for whoever takes it, so this needs one pass: registry.ts:3164 (summary) + registry.ts:3152 (docblock) → gen:upgrade-guide → check:upgrade-guide green → read i18n.json and decide explicitly.

⛔ Not a claim, not a dispatch — routing only.
