# Application asset label domains — 2 November 2026

Nine historical dynamic sites resolved by source review; no source/runtime behavior changed.

| Historical line(s) | Finite domain / fallback |
| --- | --- |
| 389 | Package labels iterate only TailoredCvText and RecruiterMessageDraft; the assetsPackage prefix therefore yields two keys. Material body remains user/application data. |
| 456/458 | tailoringLabels is a Map of six fixed title/detail tuples; unknown kinds preserve server-supplied title/detail as data. |
| 687/688 | historySources and historyAiActions are Maps with five and ten fixed values. Guarded get calls preserve unknown historical source/action labels verbatim. |
| 830 | Toolbar iterates four literal key/label pairs. |
| 857/895 | COVER_LETTER_ACTIONS is a nine-entry literal array; selection uses find with a fixed coverActionGenerate fallback. |
| 866 | Tone options iterate six literal key pairs. |

All relevant components obtain t from useI18n. The 39 distinct keys across these domains are defined in both catalogues; local assertion verified all 78 definitions. Map lookups have no inherited Object-property ambiguity. UI language and selected document-generation language remain separate. This does not activate AI, re-run PDF metrics or change canonical ownership, revision/history, entitlements, package snapshots or stored text.

The two error.messageKey sites remain pending until all error constructors/callers are traced. Key-domain review is not complete translator context, professional/native translation review or production capability acceptance. Existing unchanged contract tests were not rerun solely to record these static facts.

Machine register binds exact expressions and reviewed source hash. Reconciliation: 108 original + 37 supplemental = 145 resolved / 43 pending of 188. Do not count earlier 136/52 as additional work to add to this total.
