A refusal code or reason with no sentence fell through to the generic
"couldn't carry out that action" unnoticed: the parity test is green when
EN and HU miss the same key. One did (an edit refused for a file that is
not video or audio).
- lib/api/refusalCodes.ts: which sentence answers each code, as data;
localizeDetail says a refusal through it, unchanged for every reader.
- backendIds contract: every detail code the backend sends is in exactly
one record, every reason it can carry has its sentence in EN and HU,
and no family names a reason the backend cannot send.
- The reasons that travel in a variable are Literal types (edit, move,
cookies, quota), so the type checker refuses an unknown one too.
- downloads.errors.edit.not_media in EN and HU.
- The channel-backfill row says "running" from the runs this process has open, not from the table:
a row whose outcome failed to write no longer reads as running until a restart. The run still
going leads the row, so a newer run's outcome never sits under the older one's channel.
- Migration 0109's downgrade carries every run's trigger, spend and start in the audit row, and the
upgrade restores them: a manual run whose admin was deleted stays manual.
- Back/Forward is read by the page's one popstate listener, both halves in one render; the server
log adopts its half during that render, so no read goes out with one entry's filters and the
other's range.
- The server log's failed facets use the other tabs' words (the menus may be short); the accounts
message shows only when the menu really lacks them.
- The palette launcher's name replaced its visible "Jump to…" (and the key cap's its "Ctrl K"):
a voice-control "click Jump to" matched nothing (WCAG 2.5.3). Each name contains its text now.
- SegmentedToggle's `title` was only a tooltip on a non-focusable box — the live search's "how
many per batch" hint reached no keyboard or screen-reader user. It is the group's accessible
description, standalone and captioned alike.
- The unused-key contract let a template like `card.${status}` cover its whole namespace, which hid
five dead keys (deleted). Dynamic keys are matched by shape (`editor.*.hint`); a bare namespace
shape covers nothing, and the audit/quota namespaces are now held both ways by backendIds.
- CLAUDE.md's "FE control" row matches the lint rule it cites; each no-restricted-syntax entry has
its reason directly above it.
A contract test scans the source (tests excluded) for each key as a whole literal, or under a
dynamic prefix like `plex.sort.${k}`, with plural forms counted through their base key. It found 75
keys that had outlived the code showing them (the old sidebar sort vocabulary, the old login page, a
pager the DataTable replaced, …); they are gone from EN and HU. A key read in a way the scan cannot
see goes in an explicit ALLOWED map with its reason.
