Six strings on the two screens a user looks at most were hardcoded English
literals rather than bundle lookups. None corresponds to authorable metadata,
so no app could work around them.

Two needed no new keys at all. The list-view mode switcher named its nine
visualizations from a private VIEW_LABELS table while console.objectView.
viewType* — the same nine words — had been resolved through the bundle by the
create-view picker for months. And the create/edit dialog's close button is the
remainder of objectstack#5505: that fix reached the two Shadcn-synced
primitives via the declared patch, but MobileDialogContent is a hand-written
custom/ wrapper with its own close button, and it is exactly what ModalForm
renders.

The aggregate footer had a locale-formatted number behind a hardcoded prefix.
All eleven aggregation kinds now read grid.summary.*, and the label/value join
is its own key so a pack owns its separator. Numbers untouched (#4589's
surface). The form dialog's sr-only description fallback joins the packs too.

SettingsView converts as one unit: its sibling SettingsHub already resolved
everything through t('console.settingsHub.*') while the view routed zero
framing copy through i18n. All of it now resolves through console.settingsView.*,
including the crypto-refusal strings #4579 deliberately deferred here.

The save-bar counter was an English plural rule executing in every locale. It is
now a real i18next plural family — base + _one + _other in all ten packs — with
the base key carrying the CLDR categories ru and ar do not enumerate.

+Console chrome reaches the bundle — the list switcher, the aggregate footer, the dialog a11y fallbacks and the whole Settings namespace screen stop being English on non-English consoles
+
+Six strings on the two screens a user looks at most were hardcoded English literals rather than bundle lookups, so they stayed English on every non-English console with nothing an app could author to change them. They are not object, field, view or action labels — no key in `TranslationData` reaches them — while the console's own bundle already ships zh-CN, ja-JP, es-ES, de, fr, pt, ru, ko and ar and translates hundreds of neighbouring strings. Omissions from an otherwise complete bundle, not a missing capability.
+
+**Two of the six needed no new keys at all, which is the more interesting half.** The list-view mode switcher named its nine visualizations from a private `VIEW_LABELS` table while `console.objectView.viewType*` — the same nine words — had been resolved through the bundle by the create-view picker for months; the switcher now reads those keys, so the picker's 「画廊」 and the switcher's 「画廊」 cannot drift apart in nine languages. The create/edit dialog's close button is the remainder of a fix that already landed: objectstack#5505 routed the `sr-only` close label through `common.close` for the two Shadcn-synced primitives, but `MobileDialogContent` is a hand-written wrapper outside that regeneration zone with its own close button, and it is exactly what `ModalForm` renders — so the dialog the report measured was the one place still announcing "Close" in English.
+
+The aggregate footer is the one the original report singled out: the **number** was already locale-formatted and the **prefix** was a hardcoded `Avg: ` / `Sum: `. All eleven aggregation kinds now take their prefix from `grid.summary.*`, and the label/value join is its own key rather than a `': '` baked into the renderer — the separator is translatable content, so zh sets a fullwidth colon and fr the French space-before-colon. The numbers are untouched. The form dialog's `sr-only` description fallback joins the packs too; it is clipped, not visible, so the only way an app could displace it was to author a `description` and thereby put a visible subtitle on every dialog.
+
+**The Settings namespace screen converts as one unit.** `SettingsView` routed zero framing copy through i18n — save/failure toasts, the env-lock and crypto refusals, the load-error card, the empty-route state, the navigation buttons, the unsaved-changes save bar — while its immediate sibling `SettingsHub`, in the same directory, resolved everything through `t('console.settingsHub.*')`. A zh-CN admin read correctly translated field labels sitting inside an English save bar, because `useSettingsLabel` translates a namespace's authored content but reaches none of the chrome around it. All of it now resolves through a `console.settingsView.*` namespace placed beside the hub's, including the crypto-refusal strings that objectui#4579 deliberately left in English rather than leave one translated string among a dozen literals.
+
+The save-bar counter was an English plural rule executing in every locale (`change` plus an `s` when the count exceeds one). It is now a real i18next plural family — base key plus `_one` and `_other` in all ten packs — not the `(s)` spelling translated nine ways. The base key is the load-bearing part: i18next asks `Intl.PluralRules` for the one suffix a language needs and, finding no such slot, falls back to English, so without it Russian would read English at counts 2-20 and Arabic at 2-99. Russian and Arabic take the "noun: {count}" form their packs already use for this exact reason, and the counter is verified rendering in-language at 1, 2 and 5.
+
+The Beta badge reuses the hub's existing key rather than minting a twin, and the refusal messages interpolate their subject through the bundle instead of concatenating a translated word onto an English prefix.

+/**
+ * `SettingsView`'s framing copy speaks the session locale — objectui#4024,
+ * the SettingsView unit recorded in the card's comment.
+ *
+ * ## Why this screen is one item rather than nine
+ *
+ * Its immediate sibling already does the right thing. `SettingsHub.tsx`, in the
+ * same directory, resolves through `t('console.settingsHub.*')` against the same
+ * bundle that ships all ten packs. So this was never a missing capability or an
+ * unwired screen — it was one file written against a different convention than
+ * the file next to it, and converting it half-way would have left a single
+ * translated string among a dozen hardcoded ones. `useSettingsLabel` already
+ * translates the manifest-authored CONTENT (title, description, field labels),
+ * so a zh-CN admin saw translated field labels sitting inside an English save
+ * bar, with no key a plugin author could reach.
+ *
+ * The convention matched is therefore the sibling's, exactly: `useObjectTranslation`
+ * from `@object-ui/i18n` + a `console.settingsView.*` namespace placed beside
+ * `console.settingsHub.*` in every pack.
+ *
+ * ## The save-bar counter goes through i18next's real PLURAL mechanism
+ *
+ * `{dirtyKeys.length} unsaved change{dirtyKeys.length > 1 ? 's' : ''}` is an
+ * ENGLISH plural rule executing in every locale. Translating it as
+ * "N unsaved change(s)" would only translate the defect, so the counter is a
+ * plural family: base + `_one` + `_other`, in all ten packs.
+ *
+ * The base key is load-bearing and is not decoration. i18next asks
+ * `Intl.PluralRules` for the ONE suffix a language needs for that number and,
+ * finding no such slot, walks `fallbackLng` to `en`. `ru` has four categories
+ * (one/few/many/other) and `ar` six; no pack in this repo enumerates
+ * `_few`/`_many`/`_two`/`_zero`, so without a base key `ru` renders ENGLISH at
+ * counts 2-20. That is not hypothetical — it is objectui#3863, measured on
+ * `detail.showEmptyRelated`, and `all-locales-key-parity.test.ts` owns the rule
+ * that came out of it. The `ru` cases below at counts 1/2/5 are what prove the
+ * mechanism actually reaches a plural-rich pack rather than merely type-checking.
+ *
+ * The alternative convention in this repo — two sibling keys `xxxCount` /
+ * `xxxCountOne` (`common.itemCount`, `collaboration.commentCount`) — was
+ * deliberately NOT used: its stated rationale is a parity fear that objectui#3863's
+ * base-key fix has since answered, and it hard-codes a two-form (English-shaped)
+ * split that `ru` and `ar` do not have.
+ *
+ * ## The #4514 provider-less trap, and what was decided per test
+ *
+ * The existing settings suites mount no `I18nProvider` and assert raw English;
+ * `t()` outside a provider returns the KEY. This file mounts a provider in every
+ * case, because interpolation is the thing under test: with no provider,
+ * `t('console.settingsView.lockedByEnv', { key })` returns the bare key and the
+ * `{{key}}` hole is never filled, so a provider-less assertion could not tell a
+ * working interpolation from a broken one. The sibling suites' own disposition
+ * is recorded in their headers.
+ *
+ * ## Red-first prediction (written BEFORE the first run)
+ *
+ * Pre-fix, on `origin/main`: 7 failed, 2 passed.
+ *   - every zh/ru case FAILS — the component renders the English literal, so
+ *     `findByText('全部设置')` and friends match nothing;
+ *   - the `en` framing cases (`All settings`, `Save changes`) PASS pre-fix —
+ *     the literal equals the value the pack is about to gain, which is exactly
+ *     why nothing caught this.
+ *
+ * ONE PREDICTION IN THIS FILE WAS WRONG, and it is recorded rather than
+ * quietly corrected. The header first claimed the counter cases would go red in
+ * BOTH languages including `en`, on the reasoning that the bundle has no
+ * `console.settingsView.unsavedCount` yet. The `en` counter case PASSED pre-fix
+ * — because the concatenation it replaces (`change{n > 1 ? 's' : ''}`) IS the
+ * English plural rule, so English is precisely the one language whose output
+ * cannot change. That is the defect stated exactly: the screen was correct in
+ * English and could not be correct anywhere else. The `en` counter case is
+ * therefore a must-not-change pin, and `ru`/`zh` carry the evidence.

+ * `MobileDialogContent`'s close button speaks the session locale —

+ *
+ * ## This is a REMAINDER, not a fresh bug — and the difference matters
+ *
+ * objectstack#5505 already fixed this class: `CloseSrLabel` (`../lib/close-label`)
+ * resolves `common.close`, and `sheet-dialog-close-i18n.test.tsx` pins it for
+ * `SheetContent` and `DialogContent`. But #5505 patched the two SHADCN-SYNCED
+ * primitives under `src/ui/**`, reached by the declared patch in
+ * `scripts/shadcn-local-patches.mjs`. `custom/mobile-dialog-content.tsx` is not
+ * in that regeneration zone and carries its own hand-written close button, so
+ * it kept a hardcoded `< span className="sr-only" >Close< /span >` and no test
+ * looked at it.
+ *
+ * That is exactly the string the card reports. `MobileDialogContent` is what
+ * `plugin-form`'s `ModalForm` renders (`ModalForm.tsx:834`), so on a zh-CN
+ * console the create/edit dialog — one of the two screens the card names — is
+ * precisely where an English "Close" was still being announced. The triage seat
+ * on objectstack#5084 warned that this family was partly landed and told the
+ * implementer to reconcile with the landed fixes and "只补余量"; this file is
+ * the余量, measured rather than assumed.
+ *
+ * ## Assertions are accessible-name queries
+ *
+ * The button is icon-only (a lucide `X`), so the `sr-only` span IS its
+ * accessible name — the thing assistive tech announces and the thing
+ * `getByRole('button', { name })` matches. A `getByText` would pass on
+ * decoration.
+ *
+ * ## Red-first prediction (written BEFORE the first run)
+ *
+ * Pre-fix, on `origin/main`:
+ *   - every non-English case FAILS — the literal renders, so the button is
+ *     named "Close" in every locale and `{ name: '关闭' }` matches nothing.
+ *     The `queryByRole({ name: 'Close' })` negative assertions fail in the
+ *     other direction on the very same render, which is the bug stated twice;
+ *   - the en case PASSES pre-fix — the literal equals the `en` pack value.

+ * the fallback is to author a `description`, which makes a VISIBLE subtitle
+ * appear on every dialog. Adding visible UI to every form in order to remove an
+ * invisible untranslated string is not a trade an app should have to make.
+ *
+ * ## Assertions go through the accessible description, not `getByText`
+ *
+ * The string's whole job is to be announced, so the test asks the same question
+ * assistive tech asks: what is this dialog's accessible description? A
+ * `getByText` would pass just as well on a visible paragraph, which is the bug
+ * this fallback exists to avoid.
+ *
+ * ## Red-first prediction (written BEFORE the first run)
+ *
+ * Pre-fix, on `origin/main`:
+ *   - both zh cases FAIL — the literal is rendered verbatim, so the dialog's
+ *     accessible description is the English sentence and the expected Chinese
+ *     one is absent;
+ *   - the "authored description wins" case and the no-provider case PASS
+ *     pre-fix and after — the fallback only ever applies when the form declares
+ *     nothing, and the provider-less path must keep rendering English.

+/**
+ * The list/grid aggregate footer's PREFIX speaks the session locale —
+ * objectui#4024 (migrated from objectstack#5084).
+ *
+ * The card's sharpest observation is that this footer was already half fixed:
+ * `Avg: 39%` and `Sum: 119,200` have a correctly locale-formatted NUMBER sitting
+ * behind a hardcoded English `TYPE_LABELS` prefix. The aggregate kind is known
+ * to the renderer, so the prefix was one bundle lookup away.
+ *
+ * ## The number formatting is NOT this card's surface
+ *
+ * `#4589` landed the number-display policy in `packages/core/src/utils/**`, and
+ * the currency/percent/decimal behaviour here is pinned by the sibling
+ * `useColumnSummary.test.tsx`. This change touches the PREFIX and the
+ * label/value JOIN only; every numeric assertion below is a must-not-change,
+ * restated here so a prefix change that disturbed a number would go red in the
+ * same file that claims the prefix.
+ *
+ * ## Why a parameterized pattern rather than a translated prefix + `': '`
+ *
+ * Concatenating a translated word with a hardcoded `': '` hands the locale the
+ * word and keeps the punctuation in English. ja/zh use a fullwidth colon, and
+ * ar runs right-to-left, so the separator is translatable content. The join is
+ * therefore its own key — `grid.summary.pattern: '{{label}}: {{value}}'` — and
+ * a pack that wants 「合计:119,200」 owns the whole shape. This mirrors the
+ * `collaboration.resolvedSuffix` note already in `en.ts`: "Appended to the
+ * count, separator included, so a translator owns the whole phrase rather than
+ * inheriting an English-shaped ` · ` glue."
+ *
+ * ## Red-first prediction (written BEFORE the first run)
+ *
+ * Pre-fix, on `origin/main`:
+ *   - every zh case FAILS — `TYPE_LABELS[type]` returns the English 'Sum' /
+ *     'Avg' / 'Count' and `formatSummaryLabel` joins with a literal ': ', so
+ *     the label is 'Sum: 1,234' and the expected '合计' is absent;
+ *   - the en cases and the must-not-change numeric cases PASS pre-fix (the
+ *     English literal equals the `en` pack value — the same blindness the
+ *     switcher has).

+ * ## Red-first prediction (written BEFORE the first run)
+ *
+ * Pre-fix, on `origin/main`:
+ *   - the two zh cases FAIL — the component renders the English literal
+ *     'Grid' / 'Gallery' from `VIEW_LABELS`, never consulting the bundle, so
+ *     `getByRole('tab', { name: '表格' })` finds nothing;
+ *   - the en case and the no-provider case PASS — the English literal happens
+ *     to equal the `en` pack value, which is precisely why nothing caught this.
