+## Context
+
+The project uses i18next with JSON locale files (`src/locales/{en,ru,house}.json`). Keys are referenced in source code via `t("key")` calls, dynamic template literals (`` t(`prefix.${var}`) ``), and indirect `messageKey` patterns. There is no tooling to detect drift between locale files and code usage.
+
+Project-specific concerns:
+- `_meta.*` block in each locale is service metadata (read by `localeRegistry.ts`), not a translation key
+- `house.json` is a partial override of `ru` (incompleteness is normal; only orphan keys are errors)
+- Plural suffixes (`_one|_two|_few|_many|_other|_zero`) and ordinal suffixes (`_ordinal_*`) differ legitimately between en/ru — comparisons must use normalized base keys
+- Some keys are constructed dynamically: `` t(`repeat.month${m}`) ``, `` t(`goal.status.${status}`) ``, `messageKey` in `healingRules.ts`
+
+## Goals / Non-Goals
+
+**Goals:**
+- Statically validate all classes of i18n inconsistency (FR1–FR10)
+- Integrate into existing test suite without new runtime dependencies
+- Keep maintenance burden minimal (only `whitelist.ts` requires manual updates)
+
+**Non-Goals:**
+- Runtime checking or type generation (NG1, NG3)
+- Auto-removal of dead keys (NG2 — separate change)
+
+## Decisions
+
+### D1: Script location — `packages/client/scripts/i18n-check/`
+
+**Rationale**: The script operates exclusively on client package files. Placing it inside `packages/client` keeps paths simple and avoids cross-package imports. The `scripts/` directory separates tooling from application source.
+
+**Alternatives considered**: Root-level `tools/` directory — rejected because the script reads `src/locales` and `src/**/*.{ts,tsx}` relative to the client package.
+
+### D2: Module structure — 8 files with `index.ts` facade
+
+```
+scripts/i18n-check/
+├── index.ts       # public facade (project invariant)
+├── types.ts       # shared types
+├── flatten.ts     # JSON flattening + plural normalization
+├── scan.ts        # source file scanning for key references
+├── whitelist.ts   # explicit patterns for undetectable dynamic keys
+├── checks.ts      # 4 check functions (undefined/unused/parity/orphans)
+├── duplicates.ts  # report-only duplicate detection
+├── run.ts         # orchestrator (no process.exit)
+└── cli.ts         # entrypoint with process.exit and CLI flags
+```
+
+**Rationale**: Separation of `run.ts` (pure logic) from `cli.ts` (side effects) enables Vitest to import check logic without triggering `process.exit`. Each file stays under 200 lines (NFR-M1).
+
+### D3: Key detection strategy — regex-based static scan
+
+Two regex patterns extract keys from source:
+1. **Literal keys**: dot-separated identifiers in quotes — filtered by top-level namespace membership (from `en.json` root keys) to reject false matches like `"package.json"` or URLs
+2. **Dynamic prefixes**: template literal prefix before `${...}` — matches keys where the remainder after prefix contains no dots (for `.`-terminated prefixes) or is digits-only (for non-`.` prefixes like `repeat.month`)
+
+**Rationale**: No AST parsing needed — regex is fast (<2s) and sufficient for the project's patterns. The namespace filter eliminates most false positives without maintaining a stop-list.
+
+**Trade-off**: String concatenation (`"repeat." + x`) is not detected. This is acceptable given the project convention of using template literals; edge cases go into the whitelist.
+
+### D4: Whitelist design — explicit `RegExp` patterns with self-validation
+
+Each whitelist entry is a `{ pattern: RegExp; reason: string }`. The script validates that every pattern matches at least one key in `en.json` — stale entries become errors automatically.
+
+**Rationale**: Patterns are more expressive than simple prefix lists (can express numeric ranges like `repeat.weekday1..7`). Self-validation prevents whitelist rot.
+
+### D5: Dynamic prefix matching — conservative rest-character check
+
+A dynamic prefix `P` matches key `K` only if:
+- `P` ends with `.` AND the rest (`K` minus `P`) contains no dots, OR
+- `P` does not end with `.` AND the rest is digits-only
+
+**Rationale**: Without this restriction, prefix `repeat.month` would falsely cover `repeat.monthAndDay` or `repeat.monthGenitive1`. The conservative check ensures only intended suffixes are matched.
+
+### D6: Execution — `tsx` runner via `pnpm i18n:check`
+
+The script uses TypeScript directly via `tsx` (already a dev dependency). No compilation step needed.
+
+**Alternative**: Run only via Vitest integration test — rejected because a standalone CLI command is useful for local debugging and CI readability.
+
+### D7: Test file separation — keys in test files reported differently
+
+Keys found exclusively in test files (`*.test.*`, `*.spec.*`, `__mocks__/`, `test/`) do not trigger `undefined` errors (test fixtures may use non-existent keys). However, they are flagged in the `unused` report with a "test-only" marker.
+
+**Rationale**: Prevents test helper strings (like `"task.name"` as entity field names) from blocking CI, while still surfacing potentially dead keys.
+
+## Risks / Trade-offs
+
+- **[Risk]** New dynamic patterns in future code may not be auto-detected → **Mitigation**: Developer guide documents the two-step process: (1) use template literal with dot prefix (auto-detected), (2) if impossible, add to `whitelist.ts`
+- **[Risk]** False positives from non-i18n strings matching namespace filter (e.g., `"task.name"` as DB field) → **Mitigation**: Such strings are counted as "used", which only causes false negatives in `unused` (acceptable) — never false `undefined` errors
+- **[Risk]** Script reads all source files synchronously — could slow down on very large codebases → **Mitigation**: Current codebase is ~150 files; synchronous I/O is simpler and fast enough (NFR-P1)

+# add-i18n-check-script
+
+## Why
+
+Locale files (`src/locales/*.json`) and source code (`src/**/*.{ts,tsx}`) drift apart silently: keys get added to code but not to locale files (runtime crashes), keys accumulate in locale files after code removal (~90 unused keys today), and override locales (`house.json`) retain orphan keys for deleted base keys. There is no automated check — issues are discovered manually or by users. A static analysis script will catch all classes of i18n inconsistency on CI before merge.
+
+## What Changes
+
+- **ADDED**: Static i18n consistency check script (`packages/client/scripts/i18n-check/`) that validates locale files against source code usage
+- **ADDED**: `pnpm i18n:check` command in `packages/client/package.json`
+- **ADDED**: Vitest integration test that runs the check as part of the test suite
+
+## Capabilities
+
+### New Capabilities
+
+- `i18n-check`: Static analysis script that detects undefined keys, unused keys, locale parity violations, override orphans, and duplicate values across locale files
+
+### Modified Capabilities
+
+- `i18n`: Adds automated consistency enforcement to the existing i18n infrastructure
+
+## Goals
+
+- G1: Zero undefined/unused/parity/orphan errors pass CI undetected
+- G2: Script runs in < 2s on the current codebase
+- G3: False positive rate is zero for the current codebase (no suppressions needed for legitimate patterns)
+
+## Non-Goals
+
+- NG1: Type-safe `t()` calls via generated TypeScript declarations (future change)
+- NG2: Auto-fixing detected issues (separate `i18n-cleanup` change)
+- NG3: Runtime i18n validation or browser-side checks
+- NG4: Checking interpolation parameter consistency between locales
+
+## Users & Scenarios
+
+- U1: Developer adds a new UI string — script catches missing locale key before merge
+- U2: Developer removes a feature — script reports unused keys for cleanup
+- U3: Developer adds keys to `en.json` but forgets `ru.json` — parity check fails
+- U4: Developer edits `house.json` override with a key that no longer exists in `ru.json` — orphan check fails
+
+## Requirements
+
+### Functional
+
+- FR1: Detect keys used in production code (`src/**/*.{ts,tsx}`) that are absent from `en.json` (undefined check)
+- FR2: Detect keys present in `en.json` that are not referenced by any source file, dynamic prefix, or whitelist pattern (unused check)
+- FR3: Detect base-key set differences between `en.json` and `ru.json` after normalizing plural/ordinal suffixes (parity check)
+- FR4: Detect keys in override locales (identified by `_meta.baseLanguage`) that do not exist in their base locale (override-orphans check)
+- FR5: Report groups of keys with identical values in both `en` and `ru` as candidates for deduplication (always printed, non-blocking)
+- FR6: Recognize i18next plural suffixes (`_one|_two|_few|_many|_other|_zero`) and ordinal suffixes (`_ordinal_*`) — compare base keys only, since en/ru have different plural forms
+- FR7: Recognize dynamic key patterns from template literals (`` `prefix.${var}` ``) and exclude matched keys from unused report
+- FR8: Support an explicit whitelist for keys that cannot be detected statically (numeric suffixes, `messageKey` indirection) — each whitelist entry must match at least one existing key (stale entries are errors)
+- FR9: Exclude `_meta.*` keys from all checks (service metadata read by `localeRegistry.ts`)
+- FR10: Keys found only in test files do not trigger `undefined` errors but are flagged in `unused` report
+
+### Non-Functional
+
+#### Performance
+
+- NFR-P1: Full check completes in under 2 seconds on the current codebase (~150 source files, 4 locale files)
+
+#### Maintainability
+
+- NFR-M1: Each script module file stays under 200 lines
+- NFR-M2: Script is importable by Vitest without `process.exit` side effects (separation of logic and CLI)
+
+## UX Acceptance Criteria
+
+- UX1: On failure, output lists each error as `[kind] key — detail` with a summary count
+- UX2: On success, output is a single line: `i18n-check: OK`
+- UX3: Exit code is 1 on errors, 0 on success
+
+## Success Metrics
+
+- M1: Script detects all currently known issues (≥90 unused keys, ≥16 override orphans) when run against the unmodified codebase
+- M2: After `i18n-cleanup` change removes dead keys, script reports 0 errors on CI
+- M3: Mutation testing score ≥ 95% on flatten/scan/checks modules
+
+## Open Questions
+
+None — all resolved.

+## ADDED Requirements
+
+### Requirement: Flatten locale JSON and normalize plural keys
+
+The system SHALL flatten nested locale JSON objects into dot-separated key-value maps. The system SHALL normalize i18next plural suffixes (`_one`, `_two`, `_few`, `_many`, `_other`, `_zero`) and ordinal suffixes (`_ordinal_one`, etc.) to produce base keys for comparison.
+
+#### Scenario: Nested JSON is flattened correctly
+- **WHEN** a locale JSON contains `{ "task": { "cancel": "Cancel" } }`
+- **THEN** the flat map contains key `"task.cancel"` with value `"Cancel"`
+
+#### Scenario: Plural suffix is stripped to produce base key
+- **WHEN** a flat key is `"repeat.everyNDays_few"`
+- **THEN** the base key is `"repeat.everyNDays"`
+
+#### Scenario: Ordinal suffix is stripped to produce base key
+- **WHEN** a flat key is `"repeat.yearlyDate_ordinal_two"`
+- **THEN** the base key is `"repeat.yearlyDate"`
+
+#### Scenario: Underscore in key name is preserved
+- **WHEN** a flat key is `"filter.focused_goals"`
+- **THEN** the base key is `"filter.focused_goals"` (unchanged, since `_goals` is not a CLDR plural form)
+
+### Requirement: Scan source files for literal keys and dynamic prefixes
+
+The system SHALL scan TypeScript/TSX source files and extract:
+1. Literal keys: dot-separated identifiers in quotes/backticks that match a top-level namespace from `en.json`
+2. Dynamic prefixes: template literal content before `${...}` that contains at least one dot and matches a top-level namespace
+
+The system SHALL classify keys by file type (production vs test) based on path patterns.
+
+#### Scenario: Literal key in production file is detected
+- **WHEN** a production file contains `t("task.cancel")`
+- **THEN** `"task.cancel"` appears in `literalKeys` and NOT in `literalKeysTestOnly`
+
+#### Scenario: Literal key only in test file is flagged as test-only
+- **WHEN** a test file contains `"task.cancel"` and no production file references it
+- **THEN** `"task.cancel"` appears in `literalKeysTestOnly`
+
+#### Scenario: Dynamic prefix is extracted from template literal
+- **WHEN** a source file contains `` t(`goal.status.${status}`) ``
+- **THEN** `"goal.status."` appears in `dynamicPrefixes`
+
+#### Scenario: Non-i18n dotted string is filtered out by namespace check
+- **WHEN** a source file contains `"package.json"` and `"package"` is not a top-level namespace in `en.json`
+- **THEN** `"package.json"` is NOT included in scan results
+
+### Requirement: Detect undefined keys (FR1)
+
+The system SHALL report an error of kind `undefined` for every literal key found in production source code that does not exist as a base key in `en.json` and is not covered by a whitelist pattern.
+
+#### Scenario: Key used in code but missing from en.json
+- **WHEN** production code references `"sync.alert.repeat_rule_reset"` and this base key is absent from `en.json`
+- **THEN** an error `{ kind: "undefined", key: "sync.alert.repeat_rule_reset" }` is reported
+
+#### Scenario: Key only in test file does not trigger undefined error
+- **WHEN** `"fake.test.key"` appears only in a test file and is absent from `en.json`
+- **THEN** no `undefined` error is reported for this key
+
+### Requirement: Detect unused keys (FR2)
+
+The system SHALL report an error of kind `unused` for every base key in `en.json` that is:
+- Not found as a literal key in any source file
+- Not matched by any dynamic prefix (with conservative rest-character validation)
+- Not matched by any whitelist pattern
+
+#### Scenario: Key in en.json not referenced anywhere
+- **WHEN** `en.json` contains key `"nav.oldFeature"` and no source file references it
+- **THEN** an error `{ kind: "unused", key: "nav.oldFeature" }` is reported
+
+#### Scenario: Key matched by dynamic prefix is not reported unused
+- **WHEN** `en.json` contains `"goal.status.in_progress"` and source has `` `goal.status.${status}` ``
+- **THEN** no `unused` error is reported (prefix `"goal.status."` matches, rest `"in_progress"` has no dots)
+
+#### Scenario: Key with shared prefix but non-matching rest is still reported
+- **WHEN** `en.json` contains `"repeat.monthAndDay"` and prefix `"repeat.month"` exists from `` `repeat.month${m}` ``
+- **THEN** an `unused` error IS reported (rest `"AndDay"` is not digits-only)
+
+#### Scenario: Whitelisted key is not reported unused
+- **WHEN** `en.json` contains `"repeat.weekday3"` and whitelist has a pattern matching `repeat.weekday1..7`
+- **THEN** no `unused` error is reported
+
+### Requirement: Detect locale parity violations (FR3)
+
+The system SHALL report an error of kind `parity` for every base key that exists in `en.json` but not in `ru.json`, or vice versa.
+
+#### Scenario: Key in en missing from ru
+- **WHEN** base key `"feature.new"` exists in `en.json` but not in `ru.json`
+- **THEN** an error `{ kind: "parity", key: "feature.new", detail: "present in en, missing in ru" }` is reported
+
+#### Scenario: Key in ru missing from en
+- **WHEN** base key `"legacy.removed"` exists in `ru.json` but not in `en.json`
+- **THEN** an error `{ kind: "parity", key: "legacy.removed", detail: "present in ru, missing in en" }` is reported
+
+### Requirement: Detect override orphan keys (FR4)
+
+The system SHALL report an error of kind `override-orphans` for every base key in an override locale (where `_meta.baseLanguage` differs from locale code) that does not exist in its base locale, excluding `_meta.*` keys.
+
+#### Scenario: Override key absent from base locale
+- **WHEN** `house.json` has `_meta.baseLanguage: "ru"` and contains key `"repeat.day1"` which is absent from `ru.json`
+- **THEN** an error `{ kind: "override-orphans", key: "repeat.day1" }` is reported
+
+#### Scenario: _meta keys are excluded from orphan check
+- **WHEN** `house.json` contains `"_meta.baseLanguage"` and `"_meta.name"`
+- **THEN** no `override-orphans` error is reported for these keys
+
+### Requirement: Report duplicate values (FR5)
+
+The system SHALL always report groups of keys that have identical values in both `en.json` and `ru.json` as candidates for deduplication. This report is printed on every run (informational, does not cause a non-zero exit code).
+
+#### Scenario: Keys with same value in both locales are grouped
+- **WHEN** `en.json` has `"task.cancel": "Cancel"` and `"goal.cancel": "Cancel"`, and `ru.json` has both as `"Отмена"`
+- **THEN** a duplicate group `["task.cancel", "goal.cancel"]` is reported
+
+#### Scenario: Keys with same en value but different ru values are not grouped
+- **WHEN** `en.json` has `"repeat.month4": "April"` and `"repeat.monthGenitive4": "April"`, but `ru.json` has `"апрель"` and `"апреля"`
+- **THEN** no duplicate group is reported for these keys
+
+### Requirement: Whitelist self-validation (FR8)
+
+The system SHALL verify that every whitelist pattern matches at least one existing key in `en.json`. A pattern that matches zero keys SHALL be reported as an error.
+
+#### Scenario: Stale whitelist pattern triggers error
+- **WHEN** a whitelist pattern `/^legacy\./` matches zero keys in `en.json`
+- **THEN** an error is reported indicating the whitelist entry is stale
+
+### Requirement: CLI interface (UX1–UX3)
+
+The system SHALL provide a CLI entrypoint that:
+- Exits with code 1 when any check error is found
+- Exits with code 0 when no errors are found
+- Prints each error as `[kind] key — detail`
+- Prints summary count on failure
+- Prints `i18n-check: OK` on success
+- Always prints the duplicates report (informational section after errors)
+
+#### Scenario: Errors found — exit code 1
+- **WHEN** the check finds 3 errors
+- **THEN** CLI prints 3 error lines, a summary `i18n-check: 3 errors`, and exits with code 1
+
+#### Scenario: No errors — exit code 0
+- **WHEN** the check finds 0 errors
+- **THEN** CLI prints `i18n-check: OK` and exits with code 0

+## MODIFIED Requirements
+
+### Requirement: Locale consistency is enforced automatically
+
+The i18n system SHALL include an automated consistency check that runs as part of the test suite (`pnpm test`) and detects undefined keys, unused keys, parity violations, and override orphans. The check SHALL be available as a standalone command (`pnpm i18n:check`).
+
+#### Scenario: CI catches locale drift
+- **WHEN** a developer pushes code that references a key not present in `en.json`
+- **THEN** the test suite fails with a descriptive error identifying the missing key
+
+#### Scenario: Standalone check command

+## Context
+
+The `i18n-check` tool scans source files for translation key usage and compares against locale JSON files. Three gaps were found during review:
+
+1. **Umbrella prefixes**: `matchesDynamicPrefix` accepts any dotted prefix (e.g., `repeat.`) extracted from template literals like `` t(`repeat.${freq}`) ``. This hides all keys under that namespace, including dead ones.
+2. **Unreachable isTestOnly branch**: In `checkUnused`, `literalKeysTestOnly` is a subset of `literalKeys`, so the `literalKeys.has(baseKey)` check fires first, making the test-only detection dead code. Additionally, fixture strings in the script's own tests (e.g., `"repeat.monthAndDay"`) are picked up by the scanner as real usages.
+3. **Disabled integration test**: `i18n-check.project.test.ts` uses `it.skip` with a TODO that references work already completed.
+
+Current state: 7 dead keys survive in locale files undetected.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Fix prefix matching to catch dead keys in single-segment namespaces (FR1)
+- Make test-only detection work correctly (FR4)
+- Compensate with whitelist entries for legitimate enum keys (FR6)
+- Remove dead keys and enable the integration gate (FR7-FR9)
+
+**Non-Goals:**
+- Redesigning the whitelist DSL or scan architecture (NG1)
+- Adding new check kinds beyond existing ones (NG2)
+
+## Decisions
+
+### D1: ">=2 named segments" rule for dotted prefixes
+
+**Decision**: A dotted prefix (ending with `.`) participates in auto-matching only if the part before the trailing dot contains at least one dot itself. `goal.status.` passes (2 segments: `goal`, `status`). `repeat.` fails (1 segment: `repeat`).
+
+**Alternatives considered**:
+- (a) >=2 segments rule — **chosen**. Simple, deterministic, covers the gap.
+- (b) Full whitelist-only approach — too much manual overhead for safe two-segment prefixes.
+- (c) Heuristics (no literals in namespace → prefix valid) — fragile, rejected.
+
+**Rationale**: Single-segment namespaces are the most dangerous umbrellas because they cover an entire namespace. Two-segment prefixes are narrower and less likely to hide unrelated dead keys. Enum values for single-segment namespaces are small, bounded sets — explicit whitelist is appropriate.
+
+### D2: Fix isTestOnly by reordering conditions
+
+**Decision**: Change the condition order in `checkUnused`:
+```
+if (scan.literalKeys.has(baseKey) && !scan.literalKeysTestOnly.has(baseKey)) continue;
+```
+This allows the loop to proceed for test-only keys, reaching the `isTestOnly` reporting branch.
+
+**Rationale**: Minimal code change, preserves existing structure, makes the existing branch reachable.
+
+### D3: Synthetic namespace for test fixtures
+
+**Decision**: Rename fixture keys in `src/test/i18n-check/*.test.ts` from real namespaces (e.g., `repeat.monthAndDay`) to a synthetic `fx.` namespace (e.g., `fx.monthAndDay`). The scanner's namespace filter will exclude `fx.*` since it doesn't exist in `en.json`.
+
+**Rationale**: Prevents test fixtures from accidentally masking real dead keys. The `fx.` prefix is short, obviously synthetic, and will never appear in production locales.
+
+### D4: Whitelist entries for single-segment enum namespaces
+
+**Decision**: Add explicit `oneOf` whitelist entries for:
+- `theme.` → `[light, dark, system]`
+- `color.` → `[blue, coral, green, indigo, orange, purple, yellow]`
+- `goalFilter.` → `[all, active, paused, finished]`
+
+The existing `repeat.` whitelist entry already covers `[daily, weekly, monthly, yearly]`. `box.*` keys are all used as literals in `constants/index.ts`, so no whitelist needed.
+
+**Rationale**: These are legitimate runtime-dynamic keys. The whitelist self-validation (FR8 in spec) ensures they stay fresh.
+
+### D5: Semantic fixture isolation instead of blanket namespace ban
+
+**Decision**: The fixture-isolation requirement forbids only fixtures that coincide (after `toBaseKey` normalization) with keys actually present in `en.json`. Fixtures under real namespaces that don't match any live key (e.g., `"repeat.frequency"` after it was deleted) are permitted. An automated test enforces this, with an explicit allow-list for fixtures that must use live keys to verify the real WHITELIST.
+
+**Alternatives considered**:
+- (a) Blanket ban on real namespaces in all fixtures — too strict, forces renaming negative-test fixtures like `"repeat.frequency"` which are more readable with realistic names, and breaks whitelist verification tests.
+- (b) Semantic isolation via `toBaseKey` collision check — **chosen**. Precisely targets the dangerous case (fixture masking a live key) while allowing harmless realistic fixtures.
+
+**Rationale**: The structural guarantee (after the `checkUnused` fix, test-only keys are reported as unused) means realistic-looking fixtures that don't match live keys cannot cause false negatives. The automated test prevents drift as new keys are added to `en.json`.
+
+## Risks / Trade-offs
+
+- **[Risk] False positives after tightening** — If undiscovered single-segment dynamic namespaces exist in code, they will trigger spurious `unused` errors. → **Mitigation**: Grep for `` `[a-zA-Z]+\.\$\{` `` patterns in `src/` before removing keys. The table of namespaces was verified on the branch.
+- **[Risk] Fixture rename breaks tests** — Renaming fixture keys might break test assertions. → **Mitigation**: Update both the fixture strings AND the synthetic locale maps in the same commit; run tests immediately.
+- **[Trade-off]** Whitelist grows slightly (3 new entries) — acceptable given they are self-validating and well-commented.

+# fix-i18n-check-dynamic-prefix-gaps
+
+## Why
+
+The i18n-check tool has three gaps discovered during code review of the `i18n-cleanup` branch: (1) single-segment dynamic prefixes like `repeat.` act as umbrellas that hide dead keys, (2) the `isTestOnly` branch in `checkUnused` is unreachable dead code allowing test fixtures to mask dead keys, and (3) the integration test is disabled despite the cleanup being complete. These gaps mean 7 dead locale keys remain undetected.
+
+## What Changes
+
+- **MODIFIED**: Dynamic prefix matching rule — dotted prefixes with only one named segment (e.g., `repeat.`) no longer protect keys from being reported as unused. Only prefixes with >= 2 named segments (e.g., `goal.status.`) participate in auto-matching. Single-segment namespaces must use explicit whitelist entries.
+- **MODIFIED**: `checkUnused` logic — keys found ONLY in test files are now correctly reported as unused (with appropriate detail message), fixing unreachable `isTestOnly` branch.
+- **ADDED**: Whitelist entries for `theme.*`, `color.*`, `goalFilter.*` enum values that were previously hidden by umbrella prefixes.
+- **REMOVED**: 7 dead keys from `en.json`/`ru.json` (`repeat.frequency`, `repeat.interval`, `repeat.weeklyDays`, `repeat.monthAndDay`, `repeat.invalidRulePullAlertTitle`, `repeat.invalidRulePullAlertMessage`, `repeat.invalidRulePullAlertFix`) and 1 override from `house.json` (`repeat.weeklyDays`).
+- **MODIFIED**: Test fixtures in `src/test/i18n-check/` — rename fixture keys that collide with real namespaces to use a synthetic `fx.` prefix.
+- **ENABLED**: Integration test `i18n-check.project.test.ts` (remove `.skip`).
+
+## Capabilities
+
+### New Capabilities
+
+None.
+
+### Modified Capabilities
+
+- `i18n-check`: Dynamic prefix matching now requires >= 2 named segments for dotted prefixes; test-only key detection is functional; whitelist covers single-segment enum namespaces.
+
+## Goals
+
+- G1: Eliminate false negatives in unused key detection caused by umbrella dynamic prefixes
+- G2: Make test-only key detection functional so test fixtures cannot mask dead keys
+- G3: Enable the integration test as a Vitest gate
+
+## Non-Goals
+
+- NG1: Redesigning the whitelist format or dynamic prefix discovery mechanism
+- NG2: Adding new check types to i18n-check
+- NG3: Changing the CLI output format
+
+## Requirements
+
+### Functional
+
+- FR1: `matchesDynamicPrefix` SHALL reject dotted prefixes with only one named segment (no dot before trailing dot). Example: `repeat.` does NOT protect `repeat.frequency`.
+- FR2: `matchesDynamicPrefix` SHALL accept dotted prefixes with >= 2 named segments. Example: `goal.status.` protects `goal.status.paused`.
+- FR3: `matchesDynamicPrefix` SHALL continue to accept non-dotted prefixes with digit-only rest. Example: `repeat.month` protects `repeat.month7`.
+- FR4: `checkUnused` SHALL report keys found ONLY in test files as `unused` with detail "found ONLY in tests — likely a dead key".
+- FR5: Test fixture keys in `src/test/i18n-check/` SHALL NOT collide with real top-level namespaces from `en.json`.
+- FR6: Whitelist SHALL contain explicit `oneOf` entries for `theme.`, `color.`, and `goalFilter.` enum values.
+- FR7: Dead keys (`repeat.frequency`, `repeat.interval`, `repeat.weeklyDays`, `repeat.monthAndDay`, `repeat.invalidRulePullAlertTitle`, `repeat.invalidRulePullAlertMessage`, `repeat.invalidRulePullAlertFix`) SHALL be removed from `en.json` and `ru.json`.
+- FR8: Override orphan `repeat.weeklyDays` SHALL be removed from `house.json`.
+- FR9: Integration test `i18n-check.project.test.ts` SHALL run without `.skip`.
+
+### Non-Functional
+
+#### Performance
+
+- NFR-P1: No measurable performance regression in `pnpm i18n:check` execution time.
+
+## UX Acceptance Criteria
+
+- UX1: `pnpm i18n:check` exits with code 0 after all fixes are applied.
+- UX2: Adding a synthetic dead key (e.g., `repeat.zzzDead`) to `en.json` causes `pnpm i18n:check` to report it as unused.
+
+## Success Metrics
+
+- M1: 0 errors from `pnpm i18n:check` on clean codebase
+- M2: 7 dead keys removed from locale files
+- M3: Integration test passes without `.skip`
+- M4: Mutation score >= 95% on `checks.ts` changes (minimum >= 90%)
+
+## Impact
+
+- `packages/client/scripts/i18n-check/checks.ts` — core logic changes
+- `packages/client/scripts/i18n-check/whitelist.ts` — new entries
+- `packages/client/src/test/i18n-check/*.test.ts` — fixture renames
+- `packages/client/src/test/i18n-check/i18n-check.project.test.ts` — enable test
+- `packages/client/public/locales/en.json` — remove 7 keys
+- `packages/client/public/locales/ru.json` — remove 7 keys
+- `packages/client/public/locales/house.json` — remove 1 key
+- `openspec/specs/i18n-check/spec.md` — delta spec updates

+## MODIFIED Requirements
+
+### Requirement: Scan source files for literal keys and dynamic prefixes
+
+The system SHALL scan TypeScript/TSX source files and extract:
+1. Literal keys: dot-separated identifiers in quotes/backticks that match a top-level namespace from `en.json`
+2. Dynamic prefixes: template literal content before `${...}` that contains at least one dot and matches a top-level namespace
+
+The system SHALL classify keys by file type (production vs test) based on path patterns.
+
+The system SHALL NOT include keys from the i18n-check tool's own test fixtures in production scan results. Test fixtures SHALL use synthetic namespaces (e.g., `fx.`) that do not exist in `en.json`.
+
+#### Scenario: Literal key in production file is detected
+- **WHEN** a production file contains `t("task.cancel")`
+- **THEN** `"task.cancel"` appears in `literalKeys` and NOT in `literalKeysTestOnly`
+
+#### Scenario: Literal key only in test file is flagged as test-only
+- **WHEN** a test file contains `"task.cancel"` and no production file references it
+- **THEN** `"task.cancel"` appears in `literalKeysTestOnly`
+
+#### Scenario: Dynamic prefix is extracted from template literal
+- **WHEN** a source file contains `` t(`goal.status.${status}`) ``
+- **THEN** `"goal.status."` appears in `dynamicPrefixes`
+
+#### Scenario: Non-i18n dotted string is filtered out by namespace check
+- **WHEN** a source file contains `"package.json"` and `"package"` is not a top-level namespace in `en.json`
+- **THEN** `"package.json"` is NOT included in scan results
+
+#### Scenario: Test fixture with synthetic namespace is excluded
+- **WHEN** a test file contains `"fx.monthAndDay"` and `"fx"` is not a top-level namespace in `en.json`
+- **THEN** `"fx.monthAndDay"` is NOT included in scan results
+
+### Requirement: Detect unused keys (FR2)
+
+The system SHALL report an error of kind `unused` for every base key in `en.json` that is:
+- Not found as a literal key in any production source file (keys found ONLY in test files do not count as "found")
+- Not matched by any dynamic prefix (with conservative rest-character validation)
+- Not matched by any whitelist pattern
+
+Dynamic prefix matching for dotted prefixes (ending with `.`) SHALL require the prefix to contain >= 2 named segments (i.e., at least one dot before the trailing dot). Single-segment dotted prefixes (e.g., `repeat.`) SHALL NOT protect keys from being reported as unused — their enum values must be covered by explicit whitelist entries instead.
+
+Non-dotted prefixes SHALL continue to match when the rest is digits-only (e.g., `repeat.month` protects `repeat.month7`).
+
+Keys found ONLY in test files SHALL be reported as unused with detail "found ONLY in tests — likely a dead key".
+
+#### Scenario: Key in en.json not referenced anywhere
+- **WHEN** `en.json` contains key `"nav.oldFeature"` and no source file references it
+- **THEN** an error `{ kind: "unused", key: "nav.oldFeature" }` is reported
+
+#### Scenario: Key matched by multi-segment dynamic prefix is not reported unused
+- **WHEN** `en.json` contains `"goal.status.in_progress"` and source has `` `goal.status.${status}` ``
+- **THEN** no `unused` error is reported (prefix `"goal.status."` has 2 segments, rest `"in_progress"` has no dots)
+
+#### Scenario: Single-segment dotted prefix does NOT protect keys
+- **WHEN** `en.json` contains `"repeat.frequency"` and source has `` `repeat.${freq}` `` producing prefix `"repeat."`
+- **THEN** an `unused` error IS reported for `"repeat.frequency"` (prefix has only 1 named segment)
+
+#### Scenario: Key with shared non-dotted prefix but non-digit rest is still reported
+- **WHEN** `en.json` contains `"repeat.monthAndDay"` and prefix `"repeat.month"` exists from `` `repeat.month${m}` ``
+- **THEN** an `unused` error IS reported (rest `"AndDay"` is not digits-only)
+
+#### Scenario: Whitelisted key is not reported unused regardless of prefix rules
+- **WHEN** `en.json` contains `"repeat.daily"` and whitelist has a `oneOf("repeat.", ["daily", ...])` pattern
+- **THEN** no `unused` error is reported
+
+#### Scenario: Key found only in test files is reported as unused
+- **WHEN** `en.json` contains `"repeat.monthAndDay"` and it appears only in test files (not in production code)
+- **THEN** an error `{ kind: "unused", key: "repeat.monthAndDay", detail: "found ONLY in tests — likely a dead key" }` is reported
+
+## ADDED Requirements
+
+### Requirement: Test fixture isolation from production scan
+
+Fixture strings in the i18n-check tool's own test files SHALL NOT be able to
+affect real-project check results. Specifically, no string fixture in
+`src/test/i18n-check/*.test.ts` may coincide (after plural/ordinal
+normalization via `toBaseKey`) with a key present in `en.json`. Fixture
+strings under real namespaces that do NOT correspond to existing keys are
+permitted (e.g., negative-test fixtures like `"repeat.frequency"` for a
+deleted key), because `checkUnused` treats test-only literals as unused
+candidates and `checkUndefined` ignores test-only literals — such fixtures
+cannot shield or falsely flag anything.
+
+Exception: fixtures that verify real WHITELIST behavior (e.g., `isWhitelisted("repeat.daily")`)
+are permitted to use live keys, documented in an explicit allow-list with justification.
+
+#### Scenario: Fixture coinciding with a live key is forbidden
+- **WHEN** `en.json` contains `task.cancel` and a tool test file contains the string `"task.cancel"`
+- **THEN** the fixture-isolation test fails, naming the file and the offending string
+
+#### Scenario: Fixture under a real namespace but absent from en.json is allowed
+- **WHEN** `en.json` does not contain `repeat.frequency` and a tool test file contains the string `"repeat.frequency"`
+- **THEN** the fixture-isolation test passes
+
+#### Scenario: Whitelisted fixture for WHITELIST verification is allowed
+- **WHEN** a test verifies `isWhitelisted("repeat.daily")` against the real WHITELIST
+- **THEN** `"repeat.daily"` is permitted via the explicit allow-list with a comment justifying its presence

+## Context
+
+The i18n-check script (`packages/client/scripts/i18n-check/`) already exists and detects `undefined`, `unused`, `parity`, and `override-orphans` errors. It currently reports 121 errors: 6 undefined keys (3 `sync.alert.*` + 3 `*.attachments` prefix issues), ~90 unused keys, and 12 orphan overrides in `house.json`. The script runs locally via `pnpm i18n:check` and as a Vitest test, but is not enforced in CI.
+
+The deployment workflow (`.github/workflows/deploy.yml`) only builds — no tests, linting, or i18n checks. The QA workflow (`deploy-qa.yml`) is similar.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Fix the `sync.alert.*` bug (FR1-FR3) — highest priority, user-facing
+- Clean up dead keys so `i18n:check` passes clean (FR4-FR5)
+- Gate CI on `i18n:check` (FR8) to prevent regression
+
+**Non-Goals:**
+- Changing the i18n-check script logic (it works correctly)
+- Deduplicating shared values (separate change)
+- Adding TypeScript type safety for `t()` calls
+
+## Decisions
+
+### D1: Translation text for `sync.alert.*` keys
+
+Derive from the existing (now-unused) predecessor keys rather than inventing new copy:
+- `sync.alert.repeat_rule_reset` — based on `sync.repeatRuleCorrupted` + `sync.repeatRuleCorruptedAdvice`
+- `sync.alert.name_set_untitled` — based on `sync.nameUntitled` + `sync.nameUntitledAdvice`
+- `sync.alert.checklist_item_deleted` — based on `sync.checklistOrphaned` + `sync.checklistOrphanedAdvice`
+
+Each key combines the "what happened" and "what to do" into a single message, since `AlertOverlay` renders `t(alert.messageKey)` as a single `<p>` element — there's no separate advice field in the `SyncAlert` type.
+
+### D2: Whitelist update for `sync.alert.*`
+
+These keys are referenced via `messageKey` variable in `healingRules.ts`, not via literal `t()` calls. The scanner doesn't see them as used. Add a whitelist entry `^sync\.alert\.` with reason pointing to `healingRules.ts`.
+
+### D3: Order of operations
+
+1. Add `sync.alert.*` keys first (fix the bug)
+2. Update whitelist (so new keys don't show as unused)
+3. Update test fixtures that use dead keys
+4. Delete unused keys (bulk cleanup)
+5. Delete orphan overrides from `house.json`
+6. Add `i18n:check` to CI
+
+This order ensures the bug fix lands first and the i18n-check script validates each subsequent step.
+
+### D4: CI integration approach
+
+Add a `check` job to `deploy.yml` that runs before `build`:
+- `pnpm i18n:check` (the CLI script, exits non-zero on errors)
+
+This is simpler than adding a separate workflow file. The existing Vitest test for i18n-check also runs if tests are added to CI later.
+
+### D5: Verification of unused keys before deletion
+
+Before deleting each group, re-verify with `grep -rn` across `src/` (including `.feature` files and tests) to guard against false positives from the scanner. Keys used only in tests should be replaced with valid keys, not kept as dead locale entries.
+
+## Risks / Trade-offs
+
+- **[False unused]** A key could be used via a dynamic pattern the scanner doesn't detect → Mitigated by re-grep before deletion and running all tests after each group removal
+- **[house.json sync]** Deleting keys from base locales requires mirroring in `house.json` → The `override-orphans` check catches any missed keys
+- **[Test fixture breakage]** Tests using dead keys as fixtures will fail after key removal → Update fixtures before or alongside key deletion

+# i18n-cleanup-and-lint
+
+## Why
+
+The push self-healing system (`healingRules.ts`) references three i18n keys (`sync.alert.repeat_rule_reset`, `sync.alert.name_set_untitled`, `sync.alert.checklist_item_deleted`) that do not exist in any locale file. When self-healing triggers, users see raw keys instead of human-readable messages in the AlertOverlay. Additionally, static analysis found ~90 unused keys accumulated across `en.json`/`ru.json` and 12 orphan overrides in `house.json`, producing 121 errors from the existing `i18n:check` script. The i18n-check gate is not yet enforced in CI, so locale drift keeps accumulating.
+
+## What Changes
+
+- **ADDED**: Three missing `sync.alert.*` translation keys in `en.json`, `ru.json`, and optionally `house.json` — fixes the broken self-healing alerts
+- **REMOVED**: ~90 unused keys from `en.json`/`ru.json` and ~12 orphan overrides from `house.json`
+- **MODIFIED**: i18n-check whitelist to cover `sync.alert.*` keys (used via `messageKey` pattern, not literal `t()` calls)
+- **MODIFIED**: CI workflow to run `i18n:check` as a gate, preventing future locale drift
+- **MODIFIED**: Tests that use dead keys as fixtures (`AlertOverlay.test.tsx`, `AlertProvider.test.tsx`) — update to use valid keys
+
+## Goals
+
+- **G1**: Zero `undefined` errors from `i18n:check` — all keys referenced in production code exist in locale files
+- **G2**: Zero `unused` errors — no dead keys in locale files
+- **G3**: Zero `override-orphans` errors — `house.json` only overrides keys that exist in `ru.json`
+- **G4**: CI enforcement — locale drift detected and blocked before merge
+
+## Non-Goals
+
+- **NG1**: Deduplicating keys with identical values (e.g., "Cancel" x13) — separate change `i18n-dedupe-common-keys`
+- **NG2**: Adding TypeScript type safety for `t()` calls (e.g., `i18next-cli types`) — separate initiative
+- **NG3**: Changing the i18n-check script's core logic — it already works, just needs whitelist update and CI integration
+
+## Users & Scenarios
+
+- **U1**: User triggers push self-healing (e.g., corrupted repeat rule) — sees a localized, understandable alert message instead of a raw key
+- **U2**: Developer adds a new i18n key — CI catches if the key is missing from any required locale
+- **U3**: Developer removes a feature — CI catches if orphan keys are left behind
+
+## Requirements
+
+### Functional
+
+- **FR1**: Add `sync.alert.repeat_rule_reset` key to `en.json` and `ru.json` with text describing that a corrupted repeat rule was reset
+- **FR2**: Add `sync.alert.name_set_untitled` key to `en.json` and `ru.json` with text describing that a missing name was set to "(untitled)"
+- **FR3**: Add `sync.alert.checklist_item_deleted` key to `en.json` and `ru.json` with text describing that a checklist item was deleted because its parent task couldn't sync
+- **FR4**: Remove all keys reported as `unused` by `i18n:check` from `en.json` and `ru.json` (full list in section below)
+- **FR5**: Remove all keys reported as `override-orphans` from `house.json`
+- **FR6**: Add `sync.alert.*` pattern to the i18n-check whitelist (these keys are referenced via `messageKey` variable, not literal `t()` calls)
+- **FR7**: Update test fixtures in `AlertOverlay.test.tsx` and `AlertProvider.test.tsx` that reference dead keys to use valid keys
+- **FR8**: Add `i18n:check` step to CI workflow so locale errors block merge
+
+### Unused keys to remove (FR4)
+
+From `en.json` and `ru.json`:
+- `auth.*`: `accountSection`, `errorSignIn`, `sessionExpired`, `signInRequired`, `signOutButton`, `signedInAs`
+- `category.*`: `add`, `addTask`, `nameLabel`, `namePlaceholder`, `taskPlaceholder`
+- `context.*`: `add`, `addTask`, `nameLabel`, `namePlaceholder`, `taskPlaceholder`
+- `deleted.*`: `purgeSuccess`, `restore`
+- `filter.*`: `close`, `showHidden`
+- `goal.*`: `add`, `addTask`, `close`, `collapseDescription`, `expandDescription`, `taskPlaceholder`, `cover.closeLightbox`, `cover.uploadError`
+- `goal.attachments.*`: `empty`, `confirmDelete`, `confirmDeleteMessage`, `confirmDeleteButton`
+- `idea.*`: `add`, `addTask`, `cancel`, `cancelLabel`, `delete`, `editName`, `save`, `saveLabel`, `taskPlaceholder`
+- `idea.attachments.*`: `empty`, `confirmDelete`, `confirmDeleteMessage`, `confirmDeleteButton`
+- `nav.*`: entire block (`inbox`, `today`, `tasks`, `goals`, `ideas`, `search`, `ariaLabel`)
+- `pwa.*`: `appUpdated`, `ok`
+- `settings.*`: `detailPanelPinned`, `focusStronger`, `focusWeaker`, `fullSync`, `panelAlwaysOpen`, `syncConfigure`, `syncConnect`, `syncConnected`, `syncDisconnect`, `syncNoAuth`, `syncNotConnected`, `syncSection`, `server.initError`, `server.initializing`, `server.timeoutError`
+- `share.button`
+- `sync.*`: `checklistOrphaned`, `checklistOrphanedAdvice`, `fkCleared`, `fkClearedAdvice`, `nameUntitled`, `nameUntitledAdvice`, `rejectedBox`, `rejectedBoxAdvice`, `rejectedCorrupted`, `rejectedCorruptedAdvice`, `rejectedEntityType`, `rejectedEntityTypeAdvice`, `rejectedStatus`, `rejectedStatusAdvice`, `repeatRuleCorrupted`, `repeatRuleCorruptedAdvice`, `unauthorized`
+- `task.*`: `add`, `addPlaceholder`, `create`, `createLabel`, `newName`, `searchPlaceholder`
+- `task.attachments.*`: `confirmDelete`, `confirmDeleteMessage`, `confirmDeleteButton`
+- `taskDetail.*`: `empty`, `emptyHint`
+- `taskEdit.*`: `cancel`, `cancelLabel`, `close`, `deleteLabel`, `name`, `save`, `saveLabel`
+
+### Non-Functional
+
+#### Reliability — NFR-R1
+After cleanup, `pnpm i18n:check` exits with code 0 (zero errors).
+
+## UX Acceptance Criteria
+
+- **UX1**: When self-healing resets a repeat rule, the AlertOverlay shows a human-readable message in the user's language explaining what happened
+- **UX2**: When self-healing sets a name to "(untitled)", the AlertOverlay explains why
+- **UX3**: When self-healing deletes a checklist item, the AlertOverlay explains why
+
+## Behavior
+
+No new Gherkin features required. Existing `i18n-check` tests and `AlertOverlay` tests will be updated.
+
+## Visual Reference
+
+No visual changes — alert overlay design unchanged, only translation content changes.
+
+## Affected IA
+
+No changes.
+
+## Success Metrics
+
+- **M1**: `pnpm i18n:check` reports 0 errors (currently 121)
+- **M2**: CI blocks PRs that introduce locale drift
+- **M3**: All three `sync.alert.*` message keys render localized text in AlertOverlay
+
+## Open Questions
+
+None. `house.json` styled overrides for `sync.alert.*` are deferred — `house.json` will be fully rewritten in a separate change.

+## MODIFIED Requirements
+
+### Requirement: Detect undefined keys (FR1)
+
+The system SHALL report an error of kind `undefined` for every literal key found in production source code that does not exist as a base key in `en.json` and is not covered by a whitelist pattern.
+
+#### Scenario: Key used in code but missing from en.json
+- **WHEN** production code references `"sync.alert.repeat_rule_reset"` and this base key is absent from `en.json`
+- **THEN** an error `{ kind: "undefined", key: "sync.alert.repeat_rule_reset" }` is reported
+
+#### Scenario: Key only in test file does not trigger undefined error
+- **WHEN** `"fake.test.key"` appears only in a test file and is absent from `en.json`
+- **THEN** no `undefined` error is reported for this key
+
+#### Scenario: Key referenced via messageKey variable is covered by whitelist
+- **WHEN** `healingRules.ts` assigns `messageKey: "sync.alert.repeat_rule_reset"` and the whitelist contains a pattern matching `sync.alert.*`
+- **THEN** no `undefined` error is reported for this key (assuming the key exists in `en.json`)
+
+### Requirement: Whitelist self-validation (FR8)
+
+The system SHALL verify that every whitelist pattern matches at least one existing key in `en.json`. A pattern that matches zero keys SHALL be reported as an error.
+
+#### Scenario: Stale whitelist pattern triggers error
+- **WHEN** a whitelist pattern `/^legacy\./` matches zero keys in `en.json`
+- **THEN** an error is reported indicating the whitelist entry is stale
+
+#### Scenario: sync.alert whitelist pattern is valid
+- **WHEN** the whitelist contains pattern `^sync\.alert\.` and `en.json` contains `sync.alert.repeat_rule_reset`
+- **THEN** no stale whitelist error is reported
+
+## ADDED Requirements
+
+### Requirement: CI enforcement of locale consistency
+
+The CI pipeline SHALL run `i18n:check` before building. Any `undefined`, `unused`, `parity`, or `override-orphans` error SHALL cause the CI job to fail, preventing deployment of code with locale drift.
+
+#### Scenario: CI blocks deploy when undefined key exists
+- **WHEN** a PR introduces code referencing a key not present in `en.json`
+- **AND** CI runs `i18n:check`
+- **THEN** the CI job exits with code 1 and the PR cannot be merged
+
+#### Scenario: CI passes when all locale checks are clean
+- **WHEN** all locale keys are consistent
+- **AND** CI runs `i18n:check`
+- **THEN** the CI job exits with code 0

+
+Every translation key present in any locale file MUST exist in all other locale files (excluding `_meta`). Nested keys are compared structurally. Additionally, every key referenced by production code via `t()` or `messageKey` MUST exist in all locale files.
+
+#### Scenario: All keys present in both locales

+- **WHEN** `healingRules.ts` references `sync.alert.repeat_rule_reset`, `sync.alert.name_set_untitled`, `sync.alert.checklist_item_deleted`
+- **THEN** all three keys SHALL exist in `en.json` and `ru.json`
+- **AND** each key SHALL contain a human-readable message describing what the self-healing action did

+## Context
+
+The `i18n:check` script reports ~30 duplicate value groups across `en.json` and `ru.json`. Many are common UI labels (Cancel, Back, Delete) repeated under different domain namespaces. This noise masks real issues and increases maintenance cost.
+
+Current structure: each domain namespace (task, goal, idea, settings, etc.) defines its own copy of shared labels. All locale files use a flat namespace-based approach via i18next.
+
+Driven by G1, G2 from proposal.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Introduce a `common` namespace for shared UI labels (FR1)
+- Clean up i18n-check output by whitelisting intentional duplicates (FR4, FR5)
+- Remove dead keys (FR6)
+
+**Non-Goals:**
+- Changing i18next configuration or initialization
+- Altering how `t()` is called (just changing key strings)
+- Modifying the duplicate detection algorithm itself
+
+## Decisions
+
+### D1: `common` namespace as a top-level key in locale JSON
+
+**Decision**: Add `"common": { ... }` as a top-level key in `en.json` and `ru.json`, alongside existing namespaces like `task`, `goal`, etc.
+
+**Alternatives considered**:
+- Separate `common.json` file — adds complexity to locale loading, i18next config changes needed. Rejected per NG3/NG4.
+- i18next `defaultNS` or `fallbackNS` — would require config changes and could mask missing keys. Rejected.
+
+**Rationale**: Simplest approach. No config changes. Same `t("common.cancel")` pattern as all other keys.
+
+### D2: Which keys go into `common`
+
+**Decision**: Only keys where the value is identical across ALL current locales (en, ru) AND the semantic meaning is truly generic (UI action labels, field labels). Specifically:
+
+| Key                | EN          | RU                 | Replaces |
+|--------------------|-------------|--------------------|----------|
+| common.cancel      | Cancel      | Отмена             | 10 keys  |
+| common.back        | Back        | Назад              | 7 keys   |
+| common.delete      | Delete      | Удалить            | 5 keys   |
+| common.close       | Close       | Закрыть            | 4 keys   |
+| common.next        | Next        | Далее              | 3 keys   |
+| common.save        | Save        | Сохранить          | 2 keys   |
+| common.loading     | Loading...  | Загрузка...        | 2 keys   |
+| common.name        | Name        | Название           | 3 keys   |
+| common.taskCount   | Tasks:      | Задач:             | 3 keys   |
+| common.details     | Details     | Детали             | 2 keys   |
+| common.attachments | Attachments | Вложения           | 2 keys   |
+| common.saveName    | Save name   | Сохранить название | 2 keys   |
+
+**Rationale**: These are context-independent UI labels. Adding a 3rd language won't require diverging "Cancel" in a dialog vs "Cancel" in a button.
+
+### D3: Domain terms stay separate, get whitelisted
+
+**Decision**: Navigation/filter/section terms (inbox, today, later, tasks, goals, ideas, etc.) remain as separate keys. The whitelist gets new entries to suppress duplicate warnings.
+
+**Rationale**: In languages with grammatical cases (German, Finnish), "Inbox" as a page title may differ from "Inbox" as a filter label. Keeping them separate preserves this flexibility.
+
+### D4: Semantic pairs stay separate, get whitelisted
+
+**Decision**: Pairs like `settings.name` / `settings.settingsAriaLabel` (display vs a11y), `settings.pinDetailPanel` / `taskDetail.pin` (settings toggle vs panel button) remain separate.
+
+**Rationale**: Different semantic roles. The a11y label might diverge from the display label for screen reader clarity.
+
+### D5: Whitelist structure — group by category
+
+**Decision**: Add whitelist entries grouped by reason:
+1. Domain navigation terms (pattern matching multiple namespaces)
+2. Semantic display/a11y pairs (explicit key lists)
+
+Use `Set`-based lookup for exact keys, and existing `RegExp` patterns for prefix-based groups.
+
+### D6: saveName keys are alive
+
+**Decision**: `context.saveName` and `category.saveName` are alive — passed dynamically via `i18nKeys.saveName` object in `EntityDetailLayout` from `ContextDetailPage` and `CategoryDetailPage`. They are extracted into `common.saveName` (same value in both languages).
+
+## Risks / Trade-offs
+
+- **[Risk] Missed dynamic `t()` usage** → Before removing old keys, grep for all dynamic patterns that could construct the old key path. The i18n-check script already catches undefined keys, so CI will fail if we miss one.
+- **[Risk] Future language needs divergent translations** → Can always split a `common.*` key back into domain-specific keys. The migration is straightforward (add domain key, update `t()` call, remove from common).
+- **[Trade-off] Whitelist growth** → Adding ~15 whitelist entries is acceptable given they are well-documented and self-validating (stale entries cause errors per FR8 of i18n-check spec).

+# Deduplicate i18n Common Keys
+
+## Why
+
+The `i18n:check` script reports ~30 groups of duplicate values across `en.json` and `ru.json`. Many are genuinely shared UI labels (Cancel, Back, Delete, Close) repeated 5-10 times under different namespaces. This increases maintenance cost when adding new languages or updating wording, and creates noise in the i18n check output, masking real issues.
+
+## What Changes
+
+- **ADDED**: `common` namespace in `en.json` / `ru.json` for shared UI labels
+- **MODIFIED**: ~20 components to reference `common.*` keys instead of domain-specific duplicates
+- **REMOVED**: ~35 redundant i18n keys replaced by `common.*`
+- **MODIFIED**: `i18n-check` script whitelist to accept intentional domain-term duplicates
+- **REMOVED**: Dead keys (`context.saveName`, `category.saveName`) if confirmed unused
+
+## Capabilities
+
+### New Capabilities
+
+_None_ — this is a refactoring of existing i18n infrastructure.
+
+### Modified Capabilities
+
+- `i18n`: Adding `common` namespace convention; removing dead keys
+- `i18n-check`: Extending whitelist with intentional duplicate patterns
+
+## Goals
+
+- **G1**: Eliminate unintentional i18n key duplication — shared UI labels exist in one place
+- **G2**: Clean `i18n:check` output — zero informational duplicates reported
+
+## Non-Goals
+
+- **NG1**: Changing any user-visible text or translations
+- **NG2**: Adding new languages
+- **NG3**: Refactoring the i18n-check script beyond whitelist changes
+- **NG4**: Changing how i18next is configured or initialized
+
+## Users & Scenarios
+
+- **U1**: Developer adding a new dialog — uses `t("common.cancel")` instead of creating yet another `*.cancel` key
+- **U2**: Developer adding a 3rd language — translates `common.cancel` once instead of 10 times
+- **U3**: Developer running `i18n:check` — sees clean output without noise from known duplicates
+
+## Requirements
+
+### Functional
+
+- **FR1**: Create `common` namespace in both `en.json` and `ru.json` with shared keys: `cancel`, `back`, `delete`, `close`, `next`, `save`, `loading`, `name`, `taskCount`, `details`, `attachments`, `saveName`
+- **FR2**: Remove the original domain-specific keys that are replaced by `common.*`
+- **FR3**: Update all `t()` call sites in components to use `common.*` keys
+- **FR4**: Add whitelist entries in `i18n-check` for intentional domain-term duplicates (inbox, today, later, all, yesterday, tasks, goals, ideas, contexts, categories, memos, deleted)
+- **FR5**: Add whitelist entries for intentional semantic-pair duplicates (label vs ariaLabel, indicator vs legend, button vs type)
+- **FR6**: Extract `context.saveName` and `category.saveName` into `common.saveName` (confirmed alive — used dynamically via `i18nKeys` in `EntityDetailLayout`)
+- **FR7**: `pnpm run i18n:check` produces zero duplicate warnings after changes
+
+### Non-Functional
+
+#### Performance
+
+- **NFR-P1**: No runtime performance impact — i18next key lookup is O(1) regardless of namespace
+
+#### Accessibility
+
+- **NFR-A1**: No a11y impact — translations remain identical, only key paths change
+
+## UX Acceptance Criteria
+
+- **UX1**: All user-facing text remains exactly the same before and after the change
+- **UX2**: No missing translations — every `t()` call resolves to a valid key
+
+## Behavior
+
+No new Gherkin scenarios needed — this is a structural refactoring with no behavior change.
+
+Existing i18n BDD tests in `src/test/features/i18n/` must continue to pass.
+
+## Visual Reference
+
+No visual changes.
+
+## Affected IA
+
+No changes.
+
+## Success Metrics
+
+- **M1**: `pnpm run i18n:check` reports 0 duplicate groups (currently ~30)
+- **M2**: Net reduction of ~35 i18n keys across locale files
+- **M3**: All existing tests pass (unit, BDD, i18n-check)
+- **M4**: Build succeeds (`pnpm run build`)
+
+## Open Questions
+
+- ~~**Q1**: Are `context.saveName` and `category.saveName` truly dead keys?~~ **Resolved**: alive — passed dynamically via `i18nKeys.saveName` in `EntityDetailLayout` from `ContextDetailPage` and `CategoryDetailPage`.

+## MODIFIED Requirements
+
+### Requirement: Report duplicate values (FR5)
+
+The system SHALL always report groups of keys that have identical values in both `en.json` and `ru.json` as candidates for deduplication, UNLESS all keys in the group are covered by a duplicate-whitelist entry. This report is printed on every run (informational, does not cause a non-zero exit code).
+
+Groups where every key matches a duplicate-whitelist pattern SHALL be suppressed from the output.
+
+#### Scenario: Keys with same value in both locales are grouped
+- **WHEN** `en.json` has `"task.cancel": "Cancel"` and `"goal.cancel": "Cancel"`, and `ru.json` has both as `"Отмена"`
+- **AND** neither key is in the duplicate whitelist
+- **THEN** a duplicate group `["task.cancel", "goal.cancel"]` is reported
+
+#### Scenario: Keys with same en value but different ru values are not grouped
+- **WHEN** `en.json` has `"repeat.month4": "April"` and `"repeat.monthGenitive4": "April"`, but `ru.json` has `"апрель"` and `"апреля"`
+- **THEN** no duplicate group is reported for these keys
+
+#### Scenario: Whitelisted duplicate group is suppressed
+- **WHEN** `en.json` has `"box.inbox": "Inbox"` and `"filter.inbox": "Inbox"` with identical RU values
+- **AND** both keys match a duplicate-whitelist pattern
+- **THEN** no duplicate group is reported for these keys
+
+## ADDED Requirements
+
+### Requirement: Duplicate whitelist for intentional duplicates
+
+The system SHALL support a duplicate-value whitelist — a set of key patterns that are expected to have duplicate values across namespaces. The whitelist SHALL be defined in `whitelist.ts` alongside the existing unused-key whitelist.
+
+Whitelisted categories:
+1. **Domain navigation terms**: keys across `box`, `section`, `filter`, `search`, `deleted`, `task`, `repeat`, `goalFilter`, `idea.pageName`, `memo.pageName`, `settings.sections` that share values for the same domain concept
+2. **Semantic pairs**: keys with different UI roles (display label vs ariaLabel, indicator vs legend, button label vs type label) that happen to share the same text
+
+#### Scenario: Domain term duplicate is whitelisted
+- **WHEN** `box.inbox` and `filter.inbox` both have value "Inbox"/"Входящие"
+- **THEN** both keys match a duplicate-whitelist pattern and the group is suppressed
+
+#### Scenario: Semantic pair duplicate is whitelisted
+- **WHEN** `settings.name` and `settings.settingsAriaLabel` both have value "Settings"/"Настройки"
+- **THEN** both keys match a duplicate-whitelist pattern and the group is suppressed
+
+#### Scenario: Non-whitelisted duplicate is still reported
+- **WHEN** two keys have identical values but are not in the duplicate whitelist
+- **THEN** the duplicate group is reported as before
+
+### Requirement: Duplicate whitelist self-validation
+
+The system SHALL verify that every duplicate-whitelist pattern matches at least one existing key in `en.json`. A pattern that matches zero keys SHALL be reported as an error, consistent with the existing unused-key whitelist validation (FR8).
+
+#### Scenario: Stale duplicate-whitelist pattern triggers error
+- **WHEN** a duplicate-whitelist pattern matches zero keys in `en.json`
+- **THEN** an error is reported indicating the whitelist entry is stale

+## ADDED Requirements
+
+### Requirement: Common namespace for shared UI labels
+
+Locale files SHALL contain a `common` top-level namespace with shared UI labels that are used identically across multiple domain namespaces. Components SHALL reference `common.*` keys instead of duplicating the same label under each domain namespace.
+
+The `common` namespace SHALL include at minimum: `cancel`, `back`, `delete`, `close`, `next`, `save`, `loading`, `name`, `taskCount`, `details`, `attachments`.
+
+#### Scenario: Component uses common.cancel instead of domain-specific key
+- **WHEN** a component needs a "Cancel" button label
+- **THEN** it SHALL use `t("common.cancel")` instead of a domain-specific key like `t("goal.cancel")`
+
+#### Scenario: Common keys exist in all locale files
+- **WHEN** `en.json` contains `common.cancel`
+- **THEN** `ru.json` SHALL also contain `common.cancel` with the corresponding translation
+
+#### Scenario: Domain-specific keys replaced by common keys are removed
+- **WHEN** `common.cancel` is defined
+- **THEN** keys `task.cancel`, `goal.cancel`, `focusGoalReplacementDialog.cancel`, `idea.deleteConfirmCancel`, `settings.fullSyncCancel`, `settings.disconnectCancel`, `settings.server.cancel`, `taskEdit.deleteConfirmCancel`, `deleted.purgeCancel`, `confirmDialog.cancel` SHALL NOT exist in locale files
+
+#### Scenario: saveName keys replaced by common.saveName
+- **WHEN** `common.saveName` is defined
+- **THEN** keys `context.saveName` and `category.saveName` SHALL NOT exist in locale files
+- **AND** `EntityDetailLayout` consumers (`ContextDetailPage`, `CategoryDetailPage`) SHALL pass `"common.saveName"` via `i18nKeys.saveName`

+# Design: rework-house-locale
+
+## Context
+
+`house.json` is a dialect locale (`_meta.baseLanguage: "ru"`) that overrides `ru.json`. Since deduplicate-i18n-common-keys, missing keys fall back to the base locale, and `i18n-check` reports override keys absent from base as `override-orphans` errors. The current file predates fallback: it carries ~150 keys, many identical to base, and its terminology drifted across namespaces (4 synonyms for "task", 3 for "goal", 3 deletion verbs).
+
+Decisions below were made with the user during the explore session (2026-07-13). Context: driven by FR1–FR8 from proposal.
+
+## Goals / Non-Goals
+
+**Goals:**
+- A single glossary (Princeton-Plainsboro hospital metaphor) every current and future key must follow.
+- Minimal file: themed overrides only, everything else falls back.
+- Codified no-theming zones so humor never costs operability.
+
+**Non-Goals:**
+- No i18n runtime or tooling changes; no base-locale changes; no `en`-based House locale.
+

+
+### D2: Verb system (consistency rule)
+
+- Living entities (patients, diagnoses, epiphanies) go «в морг»; diagnoses are «сняты», epiphanies «забыты» — but all land in the morgue.
+- Structural entities (отделения) are «закрыты», never sent to the morgue.
+- restore = «реанимировать», complete = «выписать», uncomplete = «рецидив», move = «перевести», recurring = «хроническое» / «без рецидивов».
+
+### D3: No-theming zones
+
+Fallback to base is mandatory for:
+1. Accessibility-only strings: aria-labels, alt texts, SR announcements (`alert.*`, `attachment.list.*`, drag handles, checkbox marks). Exception: when the glossary verb IS the clearest label (`deleted.restoreAriaLabel` «Реанимировать {{name}}»).
+2. Data-repair and config instructions: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, invalid-repeat-rule strings.
+3. Navigation/confirmation buttons where instant readability matters: `common.cancel/save/close/back/next`, `settings.disconnectConfirm`, `commandBar.create`.
+4. Functional settings labels (language, handedness, scale, panels) and the repeat-rule configurator (all of `repeat.*` except `none`).
+
+Rule of thumb fixed with the user: jokes live in statuses, empty states, and confirmations; instructions for fixing problems stay literal.
+
+### D4: Register
+
+Direct address uses capitalized «Вы»/«Ваш» (formal address to the user). Ellipses in placeholders follow base style (`...`).
+
+### D5: Per-entity plural keys for purge counts (FR9)
+
+The old `deleted.purgeConfirmCount` interpolated six counts into one string, so i18next could not pluralize any of them («1 озарений»). Chosen fix: six per-entity keys (`deleted.purgeCountTasks`…`deleted.purgeCountIdeas`) with CLDR plural forms; `DeletedPage` composes them with `join(", ")` and passes the list as `{{items}}` into `deleted.purgeConfirmCount`. Alternatives rejected: i18next `intervalPlural` plugin (new dependency for one string), formatting in code without i18n keys (breaks locale theming — house needs «пациентов», not «задач»).
+
+### D6: Dialect plural rules resolve through baseLanguage (FR10)
+
+`Intl.PluralRules("house")` silently resolves to root rules (every count → `other`), so i18next never looks up `_one`/`_few`/`_many` keys for the house code and drops to the ru fallback with ru words. Fix: after `i18n.init()`, wrap `services.pluralResolver.getRule` to map the code through `getLocaleByCode(code)?.baseLanguage`. Alternatives rejected: renaming the locale to a valid tag `ru-house` (breaks the stored language preference, filename/`_meta.code` contract, and every "house" reference), dialect files using only `_other` forms (cannot decline at all).
+
+### D7: Phrase inventory location
+
+The normative key-by-key inventory lives in `specs/house-locale/spec.md` (single source of truth for implementation and tests). design.md holds only the rules that generated it, so future keys can be derived without re-deciding.
+
+## Risks / Trade-offs
+
+- [Humor ages or annoys daily] → Jokes concentrate in low-frequency surfaces (empty states, confirmations, sync statuses); high-frequency labels are terse glossary nouns.
+- [Non-viewers miss references] → Every phrase still states its function literally («Это никогда не волчанка» still means "nothing found"); box names chosen for comprehension over fan-service (D1: Лист ожидания).
+- [Glossary drift returns with future keys] → Glossary + zones are spec'd and covered by content tests; adding an off-glossary key fails review against this design.
+- [Removed keys regress to base unintentionally] → BDD content test asserts no override equals its base value, and i18n-check guards orphans; visual diff of the locale is part of tasks.

+# rework-house-locale
+
+## Why
+
+The Dr. House dialect locale (`house.json`) grew organically and suffers from inconsistent terminology: tasks are called «страдание», «пациент», «жалоба», or «случай» depending on the screen; goals are «иллюзии» in one place and «навязчивые идеи» in another; deletion is «ампутировать», «ликвидировать», or «удалить». Since locale fallback to the base language was implemented (deduplicate-i18n-common-keys), the file can also shed every key that merely duplicates `ru.json`. This change rebuilds the locale around a single coherent glossary (the Princeton-Plainsboro hospital metaphor) and trims it to themed-only overrides.
+
+## What Changes
+
+- **MODIFIED**: `packages/client/src/locales/house.json` is rewritten from scratch: new glossary-driven phrases (in Russian), removal of all keys identical to the `ru.json` base, removal of themed overrides for accessibility and data-repair strings.
+- **ADDED**: a documented glossary and theming rules for the House locale, enforced by automated content tests.
+- **MODIFIED**: the purge confirmation count message gains grammatical number agreement. The old single key interpolated six counts and produced «1 озарений»/«1 задач»; it is split into per-entity plural keys (`_one`/`_few`/`_many` in ru, `_one`/`_other` in en) composed into a list by `DeletedPage`.
+- The i18n mechanism and i18n-check tooling stay as-is.
+
+## Capabilities
+
+### New Capabilities
+
+- `house-locale`: content rules for the Dr. House dialect locale — fixed entity glossary, minimal-override principle, no-theming zones (accessibility, data-repair instructions, server configuration), placeholder and plural-structure parity with the base locale.
+
+### Modified Capabilities
+
+- `deleted-entities`: the purge confirmation dialog SHALL show grammatically agreed per-entity counts (new requirement).
+- `i18n`: dialect locales SHALL resolve plural rules through their base language (new requirement; without it, plural overrides in dialect files are unreachable — `Intl.PluralRules("house")` yields root rules where every count maps to `other`). `i18n-check` is untouched.
+
+## Goals
+
+- G1: One entity — one term across the entire locale (0 synonym drift for tasks, goals, ideas, boxes, deletion verbs).
+- G2: `house.json` contains only keys whose values differ from `ru.json` (0 redundant overrides).
+- G3: Themed strings never degrade accessibility or error recovery (aria/alt and repair instructions always fall back to base).
+
+## Non-Goals
+
+- NG1: No changes to i18n runtime, locale registry, or fallback mechanics — except dialect plural-rule inheritance (FR10): dialect locale codes are not BCP 47 languages, so `Intl.PluralRules` degrades them to root rules; plural rules now resolve through `_meta.baseLanguage`.
+- NG2: No changes to `ru.json` / `en.json` base locales beyond the purge-count pluralization keys of FR9.
+- NG3: No new i18n-check rules or CLI features.
+- NG4: No theming of the `context` namespace (deliberate fallback — contexts stay neutral).
+
+## Users & Scenarios
+
+- U1: A Russian-speaking user who selected the Dr. House locale sees a consistent hospital narrative: tasks are patients, goals are diagnoses, ideas are epiphanies, deleted items live in the morgue.
+- U2: A screen-reader user on the House locale hears functional labels (from base fallback) for drag handles, checkboxes, and file actions — jokes never replace operability.
+- U3: A user hitting a sync data-repair alert gets the plain base instruction, not a joke, so they can fix the problem.
+
+## Requirements
+
+### Functional
+
+- FR1: `house.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values; keys identical to base SHALL be removed (fallback covers them).
+- FR2: All themed strings SHALL use the fixed glossary terms for app entities (see design.md): task = «пациент», goal = «диагноз», idea = «озарение», category = «отделение», checklist = «назначения», attachment = «снимок», memo = «советы Уилсона», deleted = «морг», box = «палата», inbox/today/week/later/all = «Приёмный покой»/«Критические»/«Под наблюдением»/«Лист ожидания»/«Обход».
+- FR3: Action verbs SHALL be consistent: delete living entities = «в морг», delete structural entities = «закрыть», restore = «реанимировать», complete task = «выписать», hide = «карантин», purge = «кремация», move = «перевести».
+- FR4: `house.json` SHALL NOT override accessibility-only strings (aria-labels, alt texts, screen-reader position announcements), except where the glossary term itself is the clearest action name (e.g. `deleted.restoreAriaLabel` «Реанимировать {{name}}»).
+- FR5: `house.json` SHALL NOT override data-repair and configuration instruction strings: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlert*`.
+- FR6: Every overridden key SHALL preserve the interpolation placeholders (`{{count}}`, `{{date}}`, `{{name}}`, …) and plural/ordinal suffix structure of its base key.
+- FR7: `_meta` SHALL be preserved with `code: "house"`, `baseLanguage: "ru"` and remain the only namespace allowed to be absent from base.
+- FR8: All direct addresses to the user SHALL use capitalized «Вы»/«Ваш» forms.
+- FR9: The purge confirmation count message SHALL agree entity names with their counts in every locale (ru: «1 задача / 2 задачи / 5 задач»; house: «1 озарение / 2 озарения / 5 озарений»; en: «1 task / 2 tasks») via per-entity plural keys composed into a list; the house locale SHALL override the plural keys of themed entities only (contexts fall back).
+- FR10: Dialect locales (where `_meta.baseLanguage` differs from the locale code) SHALL select CLDR plural forms using the plural rules of their base language, both for keys overridden in the dialect file and for keys served via fallback.
+
+### Non-Functional
+
+#### Accessibility
+
+- NFR-A1: With the House locale active, every interactive element SHALL still expose a meaningful accessible name (via base fallback for non-themed aria keys); axe-core checks pass unchanged.
+
+## UX Acceptance Criteria
+
+- UX1: Empty states, confirmations, and statuses read as one coherent hospital story; no screen mixes two different terms for the same entity.
+- UX2: Destructive confirmation buttons (`disconnectConfirm`, `purgeConfirm`, common `cancel`/`save`) remain instantly comprehensible: either base fallback or a glossary verb whose meaning is unambiguous («Кремировать»).
+
+## UI States Matrix
+
+Not applicable — content-only change; no components or states are added or modified.
+
+## Behavior
+
+- `packages/client/src/test/features/i18n/house-locale.feature` — BDD unit scenarios (tagged `@rework-house-locale`) validating FR1–FR8 against the JSON content: no redundant overrides, no orphan keys, forbidden-zone keys absent, placeholder parity, glossary conformance for entity page names.
+
+## Visual Reference
+
+Not applicable — no visual changes; design tokens untouched.
+
+## Affected IA
+
+No changes.
+
+## Success Metrics
+
+- M1: `i18n-check` exits 0 — no `override-orphans`, no `undefined` keys.
+- M2: 0 keys in `house.json` with a value identical to `ru.json` (verified by automated test).
+- M3: 0 overridden keys inside the no-theming zones of FR4/FR5 (verified by automated test).
+- M4: 100% of overridden keys preserve base placeholders (verified by automated test).
+- M5: purge counts 0, 1, 2, 5, 21 render grammatically agreed entity names in ru, en, and house locales (verified by automated test).
+
+## Open Questions
+
+None — glossary and phrase inventory were settled during the explore session (2026-07-13).

+# Capability: deleted-entities (delta)
+
+## ADDED Requirements
+
+### Requirement: Purge confirmation shows grammatically agreed counts
+
+The purge confirmation dialog SHALL display per-entity counts with entity names grammatically agreed to the number in the active locale. Each entity count SHALL use a dedicated plural i18n key (`deleted.purgeCountTasks`, `deleted.purgeCountGoals`, `deleted.purgeCountContexts`, `deleted.purgeCountCategories`, `deleted.purgeCountChecklistItems`, `deleted.purgeCountIdeas`) with CLDR plural forms (`_one`/`_few`/`_many` for ru-based locales, `_one`/`_other` for en). The dialog SHALL compose the six rendered counts into a comma-separated list interpolated into `deleted.purgeConfirmCount` as `{{items}}`. # implements FR9 of rework-house-locale
+
+#### Scenario: Russian counts agree with numbers
+- **WHEN** the purge dialog renders in locale "ru" with 1 task, 2 goals, and 5 ideas
+- **THEN** the message contains «1 задача», «2 цели», and «5 идей»
+
+#### Scenario: House locale counts agree with numbers
+- **WHEN** the purge dialog renders in locale "house" with 1 idea and 21 tasks
+- **THEN** the message contains «1 озарение» and «21 пациент»
+
+#### Scenario: Zero counts use the many form in Russian
+- **WHEN** the purge dialog renders in locale "ru" with 0 contexts
+- **THEN** the message contains «0 контекстов»
+
+#### Scenario: English counts agree with numbers
+- **WHEN** the purge dialog renders in locale "en" with 1 task and 2 goals
+- **THEN** the message contains "1 task" and "2 goals"

+# Capability: house-locale
+
+Content rules for the Dr. House dialect locale (`packages/client/src/locales/house.json`, base `ru`).
+
+## ADDED Requirements
+
+### Requirement: Locale contains only differing overrides (FR1)
+
+`house.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in `ru.json` (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of `house.json` is compared with `ru.json`
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `house.json`
+
+### Requirement: Themed strings follow the entity glossary (FR2, FR3)
+
+All themed strings SHALL use the glossary of design.md D1 (task = «пациент», goal = «диагноз», idea = «озарение», category = «отделение», checklist item = «назначение», attachment = «снимок», deleted = «морг», box = «палата») and the verb system of D2 (delete living = «в морг», delete structural = «закрыть», restore = «реанимировать», complete = «выписать», hide = «карантин», purge = «кремация»).
+
+#### Scenario: Entity page names match glossary
+- **WHEN** reading `goal.pageName`, `idea.pageName`, `memo.pageName`, `deleted.pageName`
+- **THEN** the values are «Диагнозы», «Озарения», «Советы Уилсона», «Морг»
+
+#### Scenario: Deletion verbs are consistent
+- **WHEN** reading `common.delete`, `taskDetail.delete`, `category.deleteLabel`
+- **THEN** the values are «В морг», «В морг», «Закрыть отделение»
+
+### Requirement: Accessibility strings are not themed (FR4)
+
+`house.json` SHALL NOT override accessibility-only keys: `alert.*`, `attachment.list.*`, `attachment.lightbox.dialogLabel`, `attachment.lightbox.close`, `taskEdit.checkItemMark`, `taskEdit.checkItemUnmark`, `taskEdit.checkItemDelete`, `taskEdit.dragChecklist`, `taskEdit.checklistBadgeAriaLabel`, `taskEdit.attachmentsBadgeAriaLabel`, `settings.menuOrderDragHandle`, `settings.menuOrderToggle`, `settings.settingsAriaLabel`, `settings.loginAriaLabel`, `settings.avatarAlt`, `sync.ariaLabel`, `filter.closeSidebar`. Exception: `deleted.restoreAriaLabel` MAY be themed because the glossary verb is the clearest action name.
+
+#### Scenario: Aria keys absent from locale
+- **WHEN** `house.json` is flattened
+- **THEN** none of the listed accessibility keys are present
+
+### Requirement: Data-repair and configuration strings are not themed (FR5)
+
+`house.json` SHALL NOT override: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlertTitle`, `repeat.invalidRuleAlertMessage`, `repeat.invalidRuleAlertFix`, `auth.*`, `sidebar.*`.
+
+#### Scenario: Repair-instruction keys absent from locale
+- **WHEN** `house.json` is flattened
+- **THEN** no key from the listed namespaces is present
+
+### Requirement: Placeholder and plural parity with base (FR6)
+
+Every overridden key SHALL contain exactly the same set of `{{placeholder}}` names as its base key, and plural/ordinal suffix variants SHALL only exist where the base key has them.
+
+#### Scenario: Placeholders preserved
+- **WHEN** an overridden key's base value contains placeholders (e.g. `deleted.purgeConfirmCount`)
+- **THEN** the override contains the identical placeholder set
+
+### Requirement: Locale metadata preserved (FR7)
+
+`_meta` SHALL remain `{ code: "house", name: "Dr. House", nativeName: "Доктор Хаус", baseLanguage: "ru", emoji: "🏥" }`.
+
+#### Scenario: Metadata intact
+- **WHEN** `house.json` is loaded
+- **THEN** `_meta.code` is `house` and `_meta.baseLanguage` is `ru`
+
+### Requirement: Formal capitalized address (FR8)
+
+Strings addressing the user directly SHALL use capitalized «Вы»/«Ваш» forms (e.g. «Что Вас осенило?..», «останутся у Вас на устройстве»).
+
+#### Scenario: Capitalized address in user-facing phrases
+- **WHEN** any override contains a direct address pronoun
+- **THEN** it is written as «Вы»/«Вас»/«Ваш» with a capital letter
+
+### Requirement: Normative phrase inventory (FR1–FR3)
+
+`house.json` SHALL consist of exactly the `_meta` object and the following overrides:

+# Capability: i18n (delta)
+
+## ADDED Requirements
+
+### Requirement: Dialect locales inherit base language plural rules
+
+Dialect locales (where `_meta.baseLanguage` differs from the locale code) SHALL select CLDR plural forms using the plural rules of their base language. Dialect codes are not valid BCP 47 languages, so `Intl.PluralRules` would otherwise degrade them to root rules where every count maps to `other`, making plural overrides in dialect files unreachable. The rule applies both to keys overridden in the dialect file and to keys resolved via fallback. # implements FR10 of rework-house-locale
+
+#### Scenario: Dialect plural override uses base language forms
+- **WHEN** translating a key overridden in "house" (baseLanguage "ru") with count 21
+- **THEN** the `_one` form of the house override is used (e.g. «21 пациент»)
+
+#### Scenario: Dialect fallback keys keep base language plural forms
+- **WHEN** translating a key absent from "house" (e.g. `repeat.intervalDays`) with count 3 in locale "house"
+- **THEN** the Russian `_few` form is used («Интервал: 3 дня»)
+
+#### Scenario: Base locales are unaffected
+- **WHEN** translating a plural key in locale "ru" or "en"
+- **THEN** plural forms are selected by that locale's own rules

+# Tasks: rework-house-locale
+
+## 1. Behavior spec (RED)
+
+- [x] 1.1 Write `packages/client/src/test/features/i18n/house_locale.feature` — Gherkin scenarios tagged `@rework-house-locale` + `@FR1`…`@FR8`: no redundant overrides vs `ru.json` (FR1), no orphan keys (FR1), glossary page names and deletion verbs (FR2, FR3), accessibility keys absent (FR4), repair/config keys absent (FR5), placeholder parity for every override (FR6), `_meta` intact (FR7), capitalized «Вы» forms (FR8), flattened inventory equals the normative table from `specs/house-locale/spec.md` (no extra / no missing keys)
+- [x] 1.2 Write step definitions `house_locale.steps.ts` (vitest-cucumber) that import `house.json` + `ru.json` directly with a local flatten helper (importing from `scripts/i18n-check` would cross module boundaries); encode the normative inventory as a fixture module derived from the spec table
+- [x] 1.3 Run the new suite only (`npx vitest run src/test/features/i18n/house-locale`) — confirm scenarios FAIL against the current locale (red)
+
+## 2. Locale rewrite (GREEN)
+
+- [x] 2.1 Rewrite `packages/client/src/locales/house.json`: keep `_meta`, replace all overrides with the normative inventory from `specs/house-locale/spec.md`, delete every key not in the inventory (implements FR1–FR8)
+- [x] 2.2 Run the new suite again — confirm all scenarios PASS (green)
+
+## 3. Verification
+
+- [x] 3.1 Run `i18n-check` from `packages/client` — 0 `override-orphans`, 0 `undefined` errors (M1)
+- [x] 3.2 Run the existing i18n unit/BDD suite (one command, foreground) — locale registry still discovers `house` with valid `_meta` (NFR-A1 fallback path unchanged)
+- [x] 3.3 Call `get_file_problems` for changed files and run `pnpm run build` — no errors
+- [x] 3.4 Note: Stryker not applicable — no production TS changed (JSON content + tests only); do not launch mutation runs
+
+## 4. Purge count pluralization (FR9, added after smoke feedback)
+
+- [x] 4.1 RED: write `packages/client/src/test/features/i18n/purge_count_agreement.feature` + steps — scenarios for ru/house/en counts (0, 1, 2, 5, 21) via `i18n.t("deleted.purgeCount*", { count, lng })`, plus composed `purgeConfirmCount` with `{{items}}`; update `house_locale.inventory.ts` with new plural keys; run the two suites — confirm FAIL
+- [x] 4.2 GREEN: add per-entity plural keys (`deleted.purgeCountTasks`…`purgeCountIdeas`) to `ru.json` (`_one`/`_few`/`_many`) and `en.json` (`_one`/`_other`), switch `purgeConfirmCount` to `{{items}}` in both; override themed entities in `house.json` (contexts fall back)
+- [x] 4.3 GREEN: compose the six counts in `DeletedPage.tsx` and pass as `items` to `deleted.purgeConfirmCount`
+- [x] 4.4 GREEN: dialect plural-rule inheritance (FR10) — wrap `services.pluralResolver.getRule` in `i18n.ts` to resolve rules via `_meta.baseLanguage` (without it `Intl.PluralRules("house")` gives root rules and house plural overrides are unreachable); add a fallback-key scenario to the feature
+- [x] 4.5 Verify: both new suites green, full i18n suite green, `i18n:check` OK, `get_file_problems` clean, `pnpm run build` passes
+
+## 5. Manual smoke (single pass, not a test plan)
+
+- [x] 5.1 Switch app language to «Доктор Хаус» and walk boxes/goals/ideas/deleted/settings pages once to confirm the narrative reads coherently and nothing renders a raw key (incl. purge dialog counts)

+# Design: add-project-locales
+
+## Context
+
+`en-project.json` and `ru-project.json` are the third and fourth dialect locales, and the first *terminology* dialects: unlike the themed house/startrek locales they carry no voice, no metaphors, no jokes — only a single-term substitution (goal → project / «цель» → «проект») for users accustomed to GTD vocabulary. The mechanics are unchanged and already proven: base-language fallback, dialect plural-rule inheritance (`applyDialectPluralRules`), auto-discovery by the locale registry. All decisions below were made with the user during the explore session (2026-07-14). Context: driven by FR1–FR7 from proposal.
+
+## Goals / Non-Goals
+
+**Goals:**
+- A mechanically derivable override set: exactly the base keys whose value mentions the term — nothing editorial to maintain.
+- Twin files governed by one rule set and one content-test suite.
+- Zero ambiguity between GTD projects and the Supabase project in all locales.
+
+**Non-Goals:**
+- No i18n runtime or tooling changes; no memo theming; no wider GTD glossary; no changes to house/startrek content.
+
+## Decisions
+
+### D1: One capability for both dialects
+
+Both files implement the same substitution rule and differ only in language; they are proposed, tested, and will evolve together. One capability spec (`project-locales`) with two normative inventories beats two near-identical specs. Rejected: `en-project-locale` + `ru-project-locale` as separate capabilities (duplicated rules, double maintenance for no benefit).
+
+### D2: Inventory derived mechanically from base values
+
+The override set is defined by a rule, not by taste: a base key belongs to the inventory iff its value matches the term regex — `/\bgoals?\b/i` for en, `/(?<![а-яёА-ЯЁ])цел(ь|ью|и|ей|ям|ями|ях)(?![а-яё])/iu` for ru. The Russian variant uses Cyrillic-aware lookaround boundaries rather than `\b`, because JavaScript `\b` is ASCII-only and matches nothing around Cyrillic (same reason `locale_content.helpers.ts` already uses lookaround for `LOWERCASE_ADDRESS_REGEX`). The boundaries deliberately exclude `{{goalName}}` (placeholder names are code, not copy) and unrelated words («целиком», «в целом»). The content tests re-derive the expected set from the base files at run time and compare it with the normative inventory — so when a future base key mentions the term, the suite fails and forces the dialect update. This is the self-guarding property themed dialects cannot have. Current inventory: 26 en keys, 27 ru keys (plural forms differ: `_one/_other` vs `_one/_few/_many`).
+
+### D3: Locale codes `en-project` / `ru-project`
+
+Hyphenated codes read as language variants (BCP 47-like `lang-variant` shape), matching the UX intent: same flag emoji as the base language, `name` sorting directly after it in the switcher («English (project)» after «English»). Plural rules resolve through `baseLanguage` regardless of code shape (rework-house-locale FR10), so the non-standard subtag is harmless. Rejected: `gtd-en`/`gtd-ru` (sorts away from base languages, reads as a theme), `projecten`/`projectru` (unreadable).
+
+### D4: Fix `sync.projectPaused` in the base locales, not in the dialects
+
+"Project paused" / «Проект приостановлен» is about the Supabase backend and is ambiguous even without a GTD dialect. Changing the base wording to "Supabase paused" / «Supabase приостановлен» removes the ambiguity for every user, keeps the dialects free of overrides outside their term rule (D2), and leaves house/startrek untouched (their `sync.projectPaused` overrides still differ from the new base values, so the minimal-override invariant holds). `projectPausedDialog.*` and `settings.server.*` already name Supabase explicitly and stay as they are. Rejected: overriding `sync.projectPaused` only inside the project dialects (base users keep the ambiguity; dialect files gain a key outside the mechanical rule).
+
+### D5: Accessibility strings are substituted, not fenced off
+
+Themed dialects fence off aria strings because jokes degrade operability. A terminology substitution does not: "Drag project" / «Перетащить проект» is exactly as operable as the base string and *more* consistent for a screen-reader user who chose the dialect. So the term rule (D2) applies to all keys uniformly, including `goal.drag` and `goal.editName`. Rejected: inheriting the house/startrek no-theming zone verbatim (would leave SR users hearing «цель» in an app that everywhere else says «проект»).
+
+### D6: Content tests follow the house/startrek suite pattern
+
+One feature file (`project_locales.feature`) with scenarios parameterized over both locales, plus one inventory constant per locale in `steps/`, mirroring `startrek_locale.inventory.ts`. The spec table is the single source of truth; the inventory constants mirror it. Rejected: two separate feature files (the scenarios are identical modulo locale).
+
+## Risks / Trade-offs
+
+- [Future base keys mention the term without a dialect override] → D2's run-time derivation check fails the suite, pointing at the missing key.
+- [Term regex false positives/negatives in future copy] → Word-boundary regexes are spec'd normatively; a genuinely ambiguous future string would surface as an unexpected inventory diff and be resolved by amending the spec consciously, not silently.
+- [«проект» collides with remaining Supabase strings (`settings.server.*`, `projectPausedDialog.*`)] → Those surfaces name Supabase explicitly; the one ambiguous short status is fixed by D4.
+- [Dialect divergence: three content-rule suites (house, startrek, project) evolve separately] → Terminology dialects share only FR1/FR4-style invariants with themed ones; if a fourth dialect appears, extract a shared `dialect-locales` content-invariant spec then (same stance as startrek design).
+- [share.inviteMessage in a dialect sends "projects" to a recipient who will see "goals"] → Accepted: the invite describes the app in the sender's vocabulary; the recipient's locale is their own choice.

+# add-project-locales
+
+## Why
+
+In GTD methodology, what this app calls a «goal» is called a «project». Users coming from GTD keep stumbling over the unfamiliar term. The dialect-locale mechanism (proven by `house-locale` and `startrek-locale`) lets us offer terminology variants at zero runtime cost: two minimal dialects — `en-project` and `ru-project` — that replace goal/«цель» with project/«проект» and fall back to the base language for everything else. Additionally, the current short sync status "Project paused" / «Проект приостановлен» (about the Supabase backend) becomes ambiguous next to GTD projects, so the base locales get an unambiguous wording.
+
+## What Changes
+
+- **ADDED**: `packages/client/src/locales/en-project.json` — dialect locale (base `en`, emoji 🇺🇸) overriding only the keys whose base value mentions "goal".
+- **ADDED**: `packages/client/src/locales/ru-project.json` — dialect locale (base `ru`, emoji 🇷🇺) overriding only the keys whose base value mentions «цель», with correct masculine gender and plural agreement.
+- **MODIFIED**: `sync.projectPaused` in `en.json` and `ru.json` — "Project paused" → "Supabase paused", «Проект приостановлен» → «Supabase приостановлен» — to remove ambiguity with GTD projects (and with dialect users in general). `projectPausedDialog.*` stays unchanged (it already names Supabase explicitly).
+- No changes to the i18n mechanism, locale registry, `i18n-check` tooling, or existing dialect locales — the registry discovers the new files automatically.
+
+## Capabilities
+
+### New Capabilities
+
+- `project-locales`: content rules for the twin GTD-terminology dialect locales — exact override inventory (keys whose base value mentions goal/«цель»), terminology-only substitution (no theming, no voice), grammatical agreement rules for Russian, `_meta` exactness, placeholder and plural-structure parity, minimal-override principle.
+
+### Modified Capabilities
+
+- `project-paused-detection`: the sidebar paused-status wording changes from "Project paused" to "Supabase paused" (requirement text fixes the literal string).
+
+## Impact
+
+- `packages/client/src/locales/`: two new JSON files; two values changed in `en.json`/`ru.json`.
+- `packages/client/src/test/features/i18n/`: new BDD content suite for the twin dialects (same pattern as house/startrek suites).
+- No production TypeScript changes; no API, storage, or sync impact.
+
+## Goals
+
+- G1: A GTD-attuned user can select a locale where every user-facing mention of goal/«цель» reads project/«проект» (0 remaining goal-terminology strings in the dialect view).
+- G2: Dialect files contain only keys whose values differ from base (0 redundant overrides, 0 orphans).
+- G3: The Supabase paused status is unambiguous in every locale (0 strings where "project" could mean either GTD project or Supabase backend).
+
+## Non-Goals
+
+- NG1: No changes to i18n runtime, locale registry, fallback mechanics, plural-rule inheritance, or `i18n-check` rules.
+- NG2: No wider GTD terminology (Someday/Maybe for ideas, Next Actions, Review, etc.) — this change swaps exactly one term. A full GTD dialect can be a future change.
+- NG3: No memo theming — memos resolve by `baseLanguage`, so dialect users read base-language memos that may say «цель»/"goal" (accepted; changing memo resolution is out of scope).
+- NG4: No changes to `house.json` or `startrek.json` (their `sync.projectPaused` overrides remain valid — they still differ from the new base values).
+- NG5: No theming or voice — these are terminology dialects, not themed dialects; no jokes, no metaphors, no glossary beyond the one term.
+
+## Users & Scenarios
+
+- U1: A Russian-speaking GTD practitioner selects «Русский (проект)» and sees «Мои проекты», «Новый проект...», «Без проекта» — the app speaks their GTD vocabulary while everything else stays standard Russian.
+- U2: An English-speaking GTD practitioner selects "English (project)" and sees "My Projects", "New project...", "No project".
+- U3: A screen-reader user on a project dialect hears the same consistent terminology in accessible names ("Drag project", «Перетащить проект») — substitution never degrades operability because it is terminology-only.
+- U4: Any user whose Supabase project is paused sees "Supabase paused" / «Supabase приостановлен» in the sidebar and immediately knows it is about the backend, not their goals/projects.
+
+## Requirements
+
+### Functional
+
+- FR1: `en-project.json` and `ru-project.json` SHALL contain only keys whose values differ from the corresponding base (`en.json` / `ru.json`) values; every non-`_meta` key SHALL exist in the base file (no orphans).
+- FR2: The override set of each dialect SHALL be exactly the keys whose base value contains the word goal / «цель» (in any grammatical form), per the normative inventory in `specs/project-locales/spec.md` — no more, no fewer.
+- FR3: Every override SHALL differ from its base value only by replacing goal→project / «цель»→«проект», including required grammatical adjustments: in Russian, gender agreement (masculine: «Проект не найден», «Новый проект», «ознакомительного проекта») and plural forms («проект / проекта / проектов»); no other wording, punctuation, or tone changes.
+- FR4: Every overridden key SHALL preserve the interpolation placeholders (`{{count}}`, `{{goalName}}`, …) and the plural-suffix structure (`_one/_other` for en, `_one/_few/_many` for ru) of its base key.
+- FR5: `_meta` SHALL be exactly `{ code: "en-project", name: "English (project)", nativeName: "English (project)", baseLanguage: "en", emoji: "🇺🇸" }` and `{ code: "ru-project", name: "Russian (project)", nativeName: "Русский (проект)", baseLanguage: "ru", emoji: "🇷🇺" }`.
+- FR6: `sync.projectPaused` SHALL be "Supabase paused" in `en.json` and «Supabase приостановлен» in `ru.json`; all other `sync.*`, `projectPausedDialog.*`, and `settings.server.*` keys SHALL remain unchanged.
+- FR7: Accessibility strings that mention the term (e.g. `goal.drag`, `goal.editName`) SHALL be overridden with the same terminology substitution — unlike themed dialects, terminology dialects keep accessible names fully functional, so no no-theming zone applies to the term itself.
+
+### Non-Functional
+
+#### Accessibility
+
+- NFR-A1: With a project dialect active, every interactive element SHALL expose a meaningful accessible name — either a terminology-substituted override or base fallback; axe-core checks pass unchanged.
+
+## UX Acceptance Criteria
+
+- UX1: In the locale switcher, the dialects appear directly after their base languages ("English (project)" after "English", "Russian (project)" after "Russian" — guaranteed by sorting on English `name`) with the same flag emoji, reading as language variants rather than themes.
+- UX2: No screen in a project dialect mixes the terms: goal/«цель» never appears alongside project/«проект» (everything reachable through fallback contains no goal terminology by construction of FR2).
+- UX3: The paused-backend status is instantly attributable to Supabase in all locales.
+
+## UI States Matrix
+
+Not applicable — content-only change; no components or states are added or modified.
+
+## Behavior
+
+- `packages/client/src/test/features/i18n/project_locales.feature` — BDD unit scenarios (tagged `@add-project-locales`) validating FR1–FR7 against the JSON content: no redundant overrides, no orphan keys, inventory exactness for both files, placeholder and plural-suffix parity, `_meta` exactness, base wording of `sync.projectPaused`, absence of goal-terminology in override values.
+
+## Visual Reference
+
+Not applicable — no visual changes. The locales appear in the existing switcher with 🇺🇸/🇷🇺 emoji.
+
+## Affected IA
+
+No changes.
+
+## Success Metrics
+
+- M1: `i18n-check` exits 0 — no `override-orphans`, no `undefined` keys.
+- M2: 0 keys in either dialect file with a value identical to its base value.
+- M3: Each dialect file matches its normative inventory exactly — no missing and no extra keys (verified by automated test).
+- M4: 100% of overridden keys preserve base placeholders and plural-suffix structure (verified by automated test).
+- M5: 0 override values containing the replaced term (regex goal/«цель» in any form) and 0 base keys mentioning the term without an override (verified by automated test).
+- M6: `sync.projectPaused` equals the new wording in both base locales; `projectPausedDialog.*` byte-identical to before (verified by automated test).
+
+## Open Questions
+
+None — locale codes, names, emoji, and the base-locale wording were settled during the explore session (2026-07-14).

+# Capability: project-locales
+
+Content rules for the twin GTD-terminology dialect locales `packages/client/src/locales/en-project.json` (base `en`) and `packages/client/src/locales/ru-project.json` (base `ru`): goal → project / «цель» → «проект», nothing else.
+
+## ADDED Requirements
+
+### Requirement: Locales contain only differing overrides (FR1)
+
+`en-project.json` and `ru-project.json` SHALL contain only keys whose values differ from the corresponding base (`en.json` / `ru.json`) values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in the base file (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of each dialect file is compared with its base file
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `en-project.json` or `ru-project.json`
+
+### Requirement: Override set is exactly the term-mentioning keys (FR2)
+
+The override set of each dialect SHALL be exactly the base keys whose value matches the term regex — `/\bgoals?\b/i` for `en.json`, `/(?<![а-яёА-ЯЁ])цел(ь|ью|и|ей|ям|ями|ях)(?![а-яё])/iu` for `ru.json` — as enumerated by the normative inventories below. The Russian regex uses Cyrillic-aware lookaround boundaries because JavaScript `\b` is ASCII-only and never matches around Cyrillic (matching the existing `LOWERCASE_ADDRESS_REGEX` convention in `locale_content.helpers.ts`). Placeholder names such as `{{goalName}}` do not match (word boundary) and SHALL NOT trigger an override by themselves.
+
+#### Scenario: Inventory matches the derivation rule
+- **WHEN** the term regex is applied to every value of the base file
+- **THEN** the set of matching keys equals the key set of the normative inventory for that dialect
+
+#### Scenario: Dialect file matches the inventory exactly
+- **WHEN** each dialect file is flattened (excluding `_meta`)
+- **THEN** its key set equals the normative inventory — no missing and no extra keys
+
+### Requirement: Overrides substitute the term and nothing else (FR3)
+
+Every override SHALL differ from its base value only by replacing goal → project / «цель» → «проект», including required grammatical adjustments in Russian (masculine gender agreement and plural forms «проект / проекта / проектов»). No override value SHALL match the term regex of its base language. No other wording, punctuation, or tone changes are allowed.
+
+#### Scenario: No goal terminology survives in overrides
+- **WHEN** the base-language term regex is applied to every override value
+- **THEN** there are zero matches across both dialect files
+
+#### Scenario: Russian gender agreement
+- **WHEN** reading `goal.notFound`, `goal.empty`, `commandBar.placeholder.goal` in `ru-project.json`
+- **THEN** the values are «Проект не найден», «Нет ни одного проекта», «Новый проект...»
+
+### Requirement: Placeholder and plural parity with base (FR4)
+
+Every overridden key SHALL preserve the interpolation placeholders (`{{count}}`, `{{goalName}}`, …) and the plural-suffix structure of its base key (`_one/_other` for en, `_one/_few/_many` for ru).
+
+#### Scenario: Placeholders preserved
+- **WHEN** placeholders of every override are compared with its base value
+- **THEN** the placeholder multisets are identical
+
+#### Scenario: Plural suffix structure preserved
+- **WHEN** the plural-suffixed key groups of each dialect are compared with base
+- **THEN** every overridden plural group contains exactly the base suffix set
+
+### Requirement: Locale metadata (FR5)
+
+`_meta` SHALL be exactly `{ code: "en-project", name: "English (project)", nativeName: "English (project)", baseLanguage: "en", emoji: "🇺🇸" }` for `en-project.json` and `{ code: "ru-project", name: "Russian (project)", nativeName: "Русский (проект)", baseLanguage: "ru", emoji: "🇷🇺" }` for `ru-project.json`.
+
+#### Scenario: Metadata exactness
+- **WHEN** reading `_meta` of both dialect files
+- **THEN** every field equals the values above, and `code` matches the filename
+
+### Requirement: Accessibility strings follow the same substitution (FR7)
+
+Accessibility strings whose base value mentions the term (e.g. `goal.drag`, `goal.editName`) SHALL be overridden with the same terminology substitution. No no-theming zone applies: substitution is terminology-only and never degrades the functional meaning of an accessible name.
+
+#### Scenario: Accessible names substituted
+- **WHEN** reading `goal.drag` and `goal.editName` in both dialects
+- **THEN** the values are "Drag project" / "Edit project" and «Перетащить проект» / «Редактировать проект»
+
+### Requirement: Normative inventory — en-project (FR2, FR3)
+
+`en-project.json` SHALL contain exactly the following 26 overrides.

+# Capability: project-paused-detection (delta)
+
+Wording change only: the sidebar paused status names Supabase explicitly so it cannot be read as referring to a GTD project/goal. Detection, dialog, and recovery behavior are unchanged.
+
+## MODIFIED Requirements
+
+### Requirement: Sidebar shows project paused status
+When `syncStatus` is `"project_paused"`, the sidebar sync block SHALL display a "Supabase paused" status indicator (`sync.projectPaused`: "Supabase paused" in `en.json`, «Supabase приостановлен» in `ru.json`).
+
+#### Scenario: Sidebar displays paused status
+- **WHEN** `syncStatus` is `"project_paused"`
+- **THEN** sidebar sync block shows "Supabase paused" text with appropriate icon
+
+#### Scenario: Dialog wording unchanged
+- **WHEN** the paused-status wording is updated
+- **THEN** `projectPausedDialog.*` and `settings.server.*` values remain byte-identical to before

+# Tasks: add-project-locales
+
+## 1. Behavior spec (RED)
+
+- [x] 1.1 Write `packages/client/src/test/features/i18n/project_locales.feature` — Gherkin scenarios tagged `@add-project-locales` + `@FR1`…`@FR7`, parameterized over both dialects: no redundant overrides vs base (FR1), no orphan keys (FR1), inventory equals the run-time derivation from base via the term regexes `/\bgoals?\b/i` (en) and `/(?<![а-яёА-ЯЁ])цел(ь|ью|и|ей|ям|ями|ях)(?![а-яё])/iu` (ru; Cyrillic-aware lookaround, since `\b` is ASCII-only) (FR2), flattened files equal the normative inventories from `specs/project-locales/spec.md` (FR2, FR3), no override value matches its base-language term regex (FR3), placeholder and plural-suffix parity (FR4), `_meta` exactness incl. flags 🇺🇸/🇷🇺 (FR5), a11y keys `goal.drag`/`goal.editName` substituted (FR7), base wording `sync.projectPaused` = "Supabase paused" / «Supabase приостановлен» (FR6)
+- [x] 1.2 Write step definitions `steps/project_locales.steps.ts` (vitest-cucumber) following the `startrek_locale.steps.ts` pattern: import both dialect + base JSON files with the local flatten helper; encode the normative inventories as `steps/project_locales.inventory.ts` derived from the spec tables (single source of truth for tests)
+- [x] 1.3 Run the new suite only (`npx vitest run src/test/features/i18n/project_locales`) — confirm scenarios FAIL while the locale files do not exist (red)
+
+## 2. Locale files (GREEN)
+
+- [x] 2.1 Change `sync.projectPaused` in `packages/client/src/locales/en.json` to "Supabase paused" and in `ru.json` to «Supabase приостановлен»; touch nothing else (implements FR6 of add-project-locales)
+- [x] 2.2 Create `packages/client/src/locales/en-project.json`: `_meta` per FR5 plus exactly the 26 overrides of the normative en-project inventory (implements FR1–FR5, FR7 of add-project-locales)
+- [x] 2.3 Create `packages/client/src/locales/ru-project.json`: `_meta` per FR5 plus exactly the 27 overrides of the normative ru-project inventory (implements FR1–FR5, FR7 of add-project-locales)
+- [x] 2.4 Run the new suite again — confirm all scenarios PASS (green)
+
+## 3. Verification
+
+- [x] 3.1 Run `i18n-check` from `packages/client` — 0 `override-orphans`, 0 `undefined` errors, house/startrek untouched and still clean (M1)
+- [x] 3.2 Run the existing i18n unit/BDD suite (one command, foreground) — locale registry discovers both new codes with valid `_meta`, dialect plural rules resolve through `en`/`ru`, house and startrek suites stay green (their `sync.projectPaused` overrides still differ from the new base values)
+- [x] 3.3 Verify purge counts for `ru-project` render agreed forms for 1, 2, 5, 21 («1 проект / 2 проекта / 5 проектов / 21 проект») via the existing purge-count agreement suite pattern (M3, M4)
+- [x] 3.4 Grep the repo for tests or snapshots asserting the old literal "Project paused" / «Проект приостановлен» and update any found alongside the wording change (M6)
+- [x] 3.5 Call `get_file_problems` for changed files and run `pnpm run build` — no errors
+- [x] 3.6 Note: Stryker not applicable — no production TS changed (JSON content + tests only); do not launch mutation runs
+
+## 4. Manual smoke (single pass, not a test plan)
+
+- [x] 4.1 Switch app language to «Русский (проект)» 🇷🇺 and "English (project)" 🇺🇸, walk goals/search/deleted/command-bar/onboarding surfaces once to confirm every goal mention reads «проект»/"project", the switcher sorts the dialects next to their base languages (UX1), and no screen mixes the two terms (UX2)

+# Design: add-startrek-locale
+
+## Context
+
+`startrek.json` is the second dialect locale (`_meta.baseLanguage: "ru"`), built on the mechanics and content rules proven by `rework-house-locale`: base-language fallback, dialect plural-rule inheritance, minimal-override principle, and no-theming zones. All decisions below were made with the user during the explore sessions (2026-07-13/14). Context: driven by FR1–FR9 from proposal.
+
+## Goals / Non-Goals
+
+**Goals:**
+- A single glossary (starship Enterprise metaphor, user = captain) every current and future key must follow.
+- Minimal file: themed overrides only, everything else falls back.
+- Canon-accurate quotes (G4) with a coherent crew-to-captain voice.
+
+**Non-Goals:**
+- No i18n runtime or tooling changes; no base-locale or house-locale changes; no `en`-based Star Trek locale.
+
+## Decisions

+
+### D2: Verb and status system (consistency rule)
+
+- Tasks and goals go «за борт»; ideas «покидают орбиту»; structural entities (отсеки) are «задраены», never thrown overboard.
+- restore = «поднять на борт», purge = «отпустить в дрейф», complete = «выполнено», uncomplete = «возобновить», move = «проложить другой курс», recurring = «регулярный патруль».
+- Goal statuses: «Прокладываем курс» → «В пути» → «Стандартная орбита» (paused) → «Миссия выполнена» → «Отозвана Флотом».
+- Collision watch (UX3): «Прокладываем курс» (goal status) vs «проложить другой курс» (task move) — semantically distinct, verified not to co-occur on one surface during inventory review; fallback rename for the status: «Составляем план полёта».
+
+### D3: Voice — crew addressing the captain, with character cameos
+
+The base voice is the crew/ship computer reporting to the user as «капитан» (FR8). Character cameo lines are allowed only in low-frequency surfaces — empty states, statuses, loading, and error texts — and never on action buttons: Spock comments on illogical/empty states, Picard on goals and decisions, Scotty on loading and engineering failures, McCoy on lost connections («Связи нет, Джим. Я врач, а не связист!»). Alternatives rejected: pure crew voice (loses the best quotes), pure character mix (no coherent world), neutral narrator (no role frame). Direct address: «капитан» mid-sentence lowercase, or capitalized «Вы»/«Ваш» — same register rule as house D4.
+
+### D4: One locale for both eras (TOS + TNG)
+
+Kirk, Spock, Picard, Scotty, and McCoy coexist in one locale — one universe, one Starfleet, and twice the quote material. Alternatives rejected: TOS-only (loses «Engage!»/«Make it so» and Picard's motivational lines), TNG-only (loses «Живи долго и процветай»), two separate dialects (double inventory and maintenance for no user benefit).
+
+### D5: Canon accuracy of quotes (G4)
+
+Phrases derived from franchise quotes must be canon-accurate, based on the verified quote library collected during the explore session (~70 quotes with episode attribution, TOS S1–S3, TNG S1–S7, films marked). Known misquotes are banned in literal form: «Beam me up, Scotty» never occurred (canon form: «Scotty, beam us up»); «The needs of the many…» and «KHAAAN!» are film-era, acceptable but attributed as films in inventory comments. Russian renderings follow established translations where they exist («Живи долго и процветай», «Космос — последний рубеж», «Крайне нелогично», «Сопротивление бесполезно»); elsewhere the inventory fixes our own translation as normative.
+
+### D6: No-theming zones
+
+Identical to house D3, restated for this locale:
+1. Accessibility-only strings: aria-labels, alt texts, SR announcements. Exception: restore aria-label «Поднять на борт {{name}}» — the glossary verb is the clearest action name.
+2. Data-repair and config instructions: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `auth.*`, invalid-repeat-rule strings.
+3. Navigation/confirmation buttons where instant readability matters: `common.cancel/save/close/back/next`, `settings.disconnectConfirm`, `commandBar.create`.
+4. Functional settings labels (language, handedness, scale, panels) and the repeat-rule configurator (all of `repeat.*` except `none`).
+
+Rule of thumb (inherited from house): jokes live in statuses, empty states, and confirmations; instructions for fixing problems stay literal.
+
+### D7: Phrase inventory location
+
+The normative key-by-key inventory lives in `specs/startrek-locale/spec.md` (single source of truth for implementation and tests), mirrored by a typed inventory constant in the BDD steps. design.md holds only the rules that generated it, so future keys can be derived without re-deciding.
+
+## Risks / Trade-offs
+
+- [Humor ages or annoys daily] → Jokes concentrate in low-frequency surfaces (D3); high-frequency labels are terse glossary nouns («Задания», «Миссии», «Сканировать...»).
+- [Non-viewers miss references] → Every phrase still states its function literally; box names chosen for spatial comprehension («Ближний/Глубокий космос» read as near/far even without the show).
+- [Naval/military vocabulary feels cold for personal tasks] → Softened at the term level: «задание» over «приказ», «Машинное отделение» over «Командование Флота»; the captain frame makes remaining commands playful, not bossy.
+- [Glossary drift returns with future keys] → Glossary + zones are spec'd and covered by content tests identical in structure to the house suite; adding an off-glossary key fails review against this design.
+- [Two dialects diverge in content rules] → This change copies the house rule set verbatim where applicable (D6); a future shared `dialect-locales` spec can extract the common rules if a third dialect appears.

+# add-startrek-locale
+
+## Why
+
+The app has one dialect locale (Dr. House) proving that themed locales work on top of the base-language fallback. Star Trek is the second dialect: a Russian-language «Звёздный путь» locale where the app is the starship Enterprise and the user is its captain. The glossary, voice, and box naming were settled during the explore sessions of 2026-07-13/14; this change turns those decisions into a shipped locale built with the content rules proven by `rework-house-locale`.
+
+## What Changes
+
+- **ADDED**: `packages/client/src/locales/startrek.json` — a new dialect locale (base language `ru`, emoji 🖖) containing only themed overrides that differ from `ru.json`.
+- **ADDED**: a documented glossary, verb system, and voice rules for the Star Trek locale, enforced by automated content tests (BDD inventory, same pattern as the House locale).
+- No changes to the i18n mechanism, locale registry, `i18n-check` tooling, or existing locales — the registry discovers the new file automatically.
+
+## Capabilities
+
+### New Capabilities
+
+- `startrek-locale`: content rules for the Star Trek dialect locale — fixed entity glossary (starship metaphor), crew-to-captain voice with character cameo quotes (TOS + TNG), minimal-override principle, no-theming zones (accessibility, data-repair instructions, server configuration), placeholder and plural-structure parity with the base locale.
+
+### Modified Capabilities
+
+None — `i18n` (including dialect plural-rule inheritance) and `house-locale` are untouched.
+
+## Goals
+
+- G1: One entity — one term across the entire locale (0 synonym drift for tasks, goals, ideas, boxes, deletion verbs).
+- G2: `startrek.json` contains only keys whose values differ from `ru.json` (0 redundant overrides).
+- G3: Themed strings never degrade accessibility or error recovery (aria/alt and repair instructions always fall back to base).
+- G4: Every phrase derived from a franchise quote is canon-accurate (0 known misquotes, e.g. no literal «Beam me up, Scotty»).
+
+## Non-Goals
+
+- NG1: No changes to i18n runtime, locale registry, fallback mechanics, or plural-rule inheritance (already implemented by `rework-house-locale` FR10).
+- NG2: No changes to `ru.json`, `en.json`, or `house.json`.
+- NG3: No theming of the `context` namespace (deliberate fallback — contexts stay neutral; alternatives «пост»/«станция»/«точка высадки» were considered and rejected).
+- NG4: No new i18n-check rules or CLI features.
+- NG5: No English-based Star Trek dialect (this locale is a `ru` dialect only).
+
+## Users & Scenarios
+
+- U1: A Russian-speaking user who selected the Star Trek locale sees a consistent starship narrative: the crew reports to them as captain — ideas are new worlds, goals are missions, tasks are assignments, deleted items drift «за бортом».
+- U2: A fan recognizes character voices in designated spots (Spock on illogical states, Scotty on engineering, McCoy on lost connection) and canon-accurate references; a non-fan still understands every control because terms are self-explanatory in Russian.
+- U3: A screen-reader user on the Star Trek locale hears functional labels (from base fallback) for drag handles, checkboxes, and file actions — jokes never replace operability.
+- U4: A user hitting a sync data-repair alert gets the plain base instruction, not a joke, so they can fix the problem.
+
+## Requirements
+
+### Functional
+
+- FR1: `startrek.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values; keys identical to base SHALL be removed (fallback covers them).
+- FR2: All themed strings SHALL use the fixed glossary terms for app entities (see design.md): idea = «новый мир», goal = «миссия», task = «задание», checklist item = «директива», category = «отсек», box (generic) = «курс», inbox/today/week/later/all = «Первый контакт»/«Прямо по курсу»/«Ближний космос»/«Глубокий космос»/«Вся галактика», completed-group headers = «Журнал миссий» wording, memo = «Журнал капитана», deleted = «За бортом», attachment = «голозапись», search = «сканирование», sync = «телеметрия», settings = «Машинное отделение».
+- FR3: Action verbs SHALL be consistent: delete tasks/goals = «за борт», delete idea = «покинуть орбиту», delete structural entities (category) = «задраить», restore from bin = «поднять на борт», purge = «отпустить в дрейф», complete task = «выполнено», uncomplete = «возобновить», hide = «включить маскировку», unhide = «снять маскировку», move between boxes = «проложить другой курс», recurring = «регулярный патруль».
+- FR4: `startrek.json` SHALL NOT override accessibility-only strings (aria-labels, alt texts, screen-reader position announcements), except where the glossary term itself is the clearest action name (e.g. restore aria-label «Поднять на борт {{name}}»).
+- FR5: `startrek.json` SHALL NOT override data-repair and configuration instruction strings: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlert*`, `auth.*`.
+- FR6: Every overridden key SHALL preserve the interpolation placeholders (`{{count}}`, `{{date}}`, `{{name}}`, …) and plural/ordinal suffix structure of its base key.
+- FR7: `_meta` SHALL be `{ code: "startrek", name: "Star Trek", nativeName: "Звёздный путь", baseLanguage: "ru", emoji: "🖖" }`.
+- FR8: The locale voice SHALL be the crew addressing the user as «капитан» (lowercase mid-sentence); where base keys address the user directly, overrides SHALL use either the «капитан» address or capitalized «Вы»/«Ваш» forms; character cameo lines (Spock, Picard, Scotty, McCoy) are allowed only in empty states, statuses, loading, and error texts — never on action buttons.
+- FR9: Sync status strings SHALL stay short enough for the status indicator: no themed sync string may exceed its `ru.json` counterpart by more than 10 characters.
+
+### Non-Functional
+
+#### Accessibility
+
+- NFR-A1: With the Star Trek locale active, every interactive element SHALL still expose a meaningful accessible name (via base fallback for non-themed aria keys); axe-core checks pass unchanged.
+
+## UX Acceptance Criteria
+
+- UX1: Empty states, confirmations, and statuses read as one coherent starship story; no screen mixes two different terms for the same entity.
+- UX2: Destructive confirmation buttons remain instantly comprehensible: either base fallback or a glossary verb whose meaning is unambiguous; the purge confirmation states irreversibility explicitly («Отпустить в дрейф» + plain-language warning).
+- UX3: The «Прокладываем курс» goal status and the «Проложить другой курс» move action never appear side by side on one screen with conflicting meaning (verified during inventory review).
+
+## UI States Matrix
+
+Not applicable — content-only change; no components or states are added or modified.
+
+## Behavior
+
+- `packages/client/src/test/features/i18n/startrek_locale.feature` — BDD unit scenarios (tagged `@add-startrek-locale`) validating FR1–FR9 against the JSON content: no redundant overrides, no orphan keys, forbidden-zone keys absent, placeholder parity, glossary conformance, `_meta` exactness, sync string length budget.
+
+## Visual Reference
+
+Not applicable — no visual changes; design tokens untouched. The locale emoji 🖖 appears in the existing locale switcher.
+
+## Affected IA
+
+No changes.
+
+## Success Metrics
+
+- M1: `i18n-check` exits 0 — no `override-orphans`, no `undefined` keys.
+- M2: 0 keys in `startrek.json` with a value identical to `ru.json` (verified by automated test).
+- M3: 0 overridden keys inside the no-theming zones of FR4/FR5 (verified by automated test).
+- M4: 100% of overridden keys preserve base placeholders and plural suffix structure (verified by automated test).
+- M5: `startrek.json` matches the normative phrase inventory exactly — no missing and no extra keys (verified by automated test).
+- M6: 0 themed sync strings exceeding the FR9 length budget (verified by automated test).
+
+## Open Questions
+
+None — glossary, voice, box naming, and emoji were settled during the explore sessions (2026-07-13/14).

+# Capability: startrek-locale
+
+Content rules for the Star Trek dialect locale (`packages/client/src/locales/startrek.json`, base `ru`).
+
+## ADDED Requirements
+
+### Requirement: Locale contains only differing overrides (FR1)
+
+`startrek.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in `ru.json` (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of `startrek.json` is compared with `ru.json`
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `startrek.json`
+
+### Requirement: Themed strings follow the entity glossary (FR2, FR3)
+
+All themed strings SHALL use the glossary of design.md D1 (idea = «новый мир», goal = «миссия», task = «задание», checklist item = «директива», category = «отсек», box = «курс», attachment = «голозапись», memo = «Журнал капитана», deleted = «За бортом») and the verb system of D2 (delete = «за борт», delete idea = «покинуть орбиту», delete structural = «задраить», restore = «поднять на борт», purge = «отпустить в дрейф», hide = «маскировка», move = «проложить другой курс»).
+
+#### Scenario: Entity page names match glossary
+- **WHEN** reading `goal.pageName`, `idea.pageName`, `memo.pageName`, `deleted.pageName`
+- **THEN** the values are «Миссии», «Новые миры», «Журнал капитана», «За бортом»
+
+#### Scenario: Deletion verbs are consistent
+- **WHEN** reading `common.delete`, `taskDetail.delete`, `category.deleteLabel`, `idea.deleteLabel`
+- **THEN** the values are «За борт», «За борт», «Задраить отсек», «Покинуть орбиту»
+
+### Requirement: Accessibility strings are not themed (FR4)
+
+`startrek.json` SHALL NOT override accessibility-only keys: `alert.*`, `attachment.list.*`, `attachment.lightbox.dialogLabel`, `attachment.lightbox.close`, `taskEdit.checkItemMark`, `taskEdit.checkItemUnmark`, `taskEdit.checkItemDelete`, `taskEdit.dragChecklist`, `taskEdit.checklistBadgeAriaLabel`, `taskEdit.attachmentsBadgeAriaLabel`, `settings.menuOrderDragHandle`, `settings.menuOrderToggle`, `settings.settingsAriaLabel`, `settings.loginAriaLabel`, `settings.avatarAlt`, `sync.ariaLabel`, `filter.closeSidebar`. Exception: `deleted.restoreAriaLabel` MAY be themed because the glossary verb is the clearest action name.
+
+#### Scenario: Aria keys absent from locale
+- **WHEN** `startrek.json` is flattened
+- **THEN** none of the listed accessibility keys are present
+
+### Requirement: Data-repair and configuration strings are not themed (FR5)
+
+`startrek.json` SHALL NOT override: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlertTitle`, `repeat.invalidRuleAlertMessage`, `repeat.invalidRuleAlertFix`, `auth.*`, `sidebar.*`.
+
+#### Scenario: Repair-instruction keys absent from locale
+- **WHEN** `startrek.json` is flattened
+- **THEN** no key from the listed namespaces is present
+
+### Requirement: Placeholder and plural parity with base (FR6)
+
+Every overridden key SHALL contain exactly the same set of `{{placeholder}}` names as its base key, and plural/ordinal suffix variants SHALL only exist where the base key has them.
+
+#### Scenario: Placeholders preserved
+- **WHEN** an overridden key's base value contains placeholders (e.g. `deleted.purgeConfirmCount`)
+- **THEN** the override contains the identical placeholder set
+
+### Requirement: Locale metadata (FR7)
+
+`_meta` SHALL be `{ code: "startrek", name: "Star Trek", nativeName: "Звёздный путь", baseLanguage: "ru", emoji: "🖖" }`.
+
+#### Scenario: Metadata exact
+- **WHEN** `startrek.json` is loaded
+- **THEN** `_meta.code` is `startrek`, `_meta.baseLanguage` is `ru`, and `_meta.emoji` is «🖖»
+
+### Requirement: Crew-to-captain voice and address register (FR8)
+
+The locale voice SHALL be the crew addressing the user as «капитан» (lowercase mid-sentence). Where overrides address the user directly, they SHALL use either the «капитан» address or capitalized «Вы»/«Ваш» forms. Character cameo lines appear only in empty states, statuses, and error texts — never on action buttons.
+
+#### Scenario: Capitalized address in user-facing phrases
+- **WHEN** any override contains a direct address pronoun
+- **THEN** it is written as «Вы»/«Вас»/«Ваш» with a capital letter
+
+#### Scenario: Captain address is lowercase
+- **WHEN** any override contains the word «капитан» as an address mid-sentence
+- **THEN** it is written in lowercase
+
+### Requirement: Sync status strings stay short (FR9)
+
+No themed `sync.*` string SHALL exceed its `ru.json` counterpart by more than 10 characters.
+
+#### Scenario: Length budget respected
+- **WHEN** each themed `sync.*` value is compared with its base value
+- **THEN** `themed.length <= base.length + 10`
+
+### Requirement: Normative phrase inventory (FR1–FR3)
+

+# Tasks: add-startrek-locale
+
+## 1. Behavior spec (RED)
+
+- [x] 1.1 Write `packages/client/src/test/features/i18n/startrek_locale.feature` — Gherkin scenarios tagged `@add-startrek-locale` + `@FR1`…`@FR9`: no redundant overrides vs `ru.json` (FR1), no orphan keys (FR1), glossary page names and deletion verbs (FR2, FR3), accessibility keys absent (FR4), repair/config keys absent (FR5), placeholder parity for every override (FR6), `_meta` exact incl. emoji 🖖 (FR7), capitalized «Вы» forms and lowercase «капитан» address (FR8), sync string length budget vs base (FR9), flattened inventory equals the normative table from `specs/startrek-locale/spec.md` (no extra / no missing keys)
+- [x] 1.2 Write step definitions `startrek_locale.steps.ts` (vitest-cucumber) following the `house_locale.steps.ts` pattern: import `startrek.json` + `ru.json` directly with the local flatten helper; encode the normative inventory as `steps/startrek_locale.inventory.ts` derived from the spec table (single source of truth for tests)
+- [x] 1.3 Run the new suite only (`npx vitest run src/test/features/i18n/startrek_locale`) — confirm scenarios FAIL while the locale file does not exist (red)
+
+## 2. Locale file (GREEN)
+
+- [x] 2.1 Create `packages/client/src/locales/startrek.json`: `_meta` per FR7 plus exactly the overrides of the normative inventory from `specs/startrek-locale/spec.md` (implements FR1–FR9 of add-startrek-locale)
+- [x] 2.2 Run the new suite again — confirm all scenarios PASS (green)
+
+## 3. Verification
+
+- [x] 3.1 Run `i18n-check` from `packages/client` — 0 `override-orphans`, 0 `undefined` errors (M1)
+- [x] 3.2 Run the existing i18n unit/BDD suite (one command, foreground) — locale registry discovers `startrek` with valid `_meta`, dialect plural rules resolve through `ru` for the new locale (existing `applyDialectPluralRules` path), house suite untouched and green
+- [x] 3.3 Verify purge counts for the startrek locale render agreed forms for 1, 2, 5, 21 («1 задание / 2 задания / 5 заданий», «1 мир / 2 мира / 5 миров») via the existing purge-count agreement suite pattern (M4)
+- [x] 3.4 Call `get_file_problems` for changed files and run `pnpm run build` — no errors
+- [x] 3.5 Note: Stryker not applicable — no production TS changed (JSON content + tests only); do not launch mutation runs
+
+## 4. Manual smoke (single pass, not a test plan)
+
+- [x] 4.1 Switch app language to «Звёздный путь» 🖖 and walk boxes/goals/ideas/deleted/settings pages once to confirm the crew-to-captain narrative reads coherently, nothing renders a raw key, and «Прокладываем курс» / «Проложить другой курс» do not co-occur confusingly on one screen (UX3)

+# Capability: house-locale
+
+## Purpose
+
+Content rules for the Dr. House dialect locale (`packages/client/src/locales/house.json`, base `ru`).
+
+## Requirements
+
+### Requirement: Locale contains only differing overrides (FR1)
+
+`house.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in `ru.json` (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of `house.json` is compared with `ru.json`
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `house.json`
+
+### Requirement: Themed strings follow the entity glossary (FR2, FR3)
+
+All themed strings SHALL use the glossary of design.md D1 (task = «пациент», goal = «диагноз», idea = «озарение», category = «отделение», checklist item = «назначение», attachment = «снимок», deleted = «морг», box = «палата») and the verb system of D2 (delete living = «в морг», delete structural = «закрыть», restore = «реанимировать», complete = «выписать», hide = «карантин», purge = «кремация»).
+
+#### Scenario: Entity page names match glossary
+- **WHEN** reading `goal.pageName`, `idea.pageName`, `memo.pageName`, `deleted.pageName`
+- **THEN** the values are «Диагнозы», «Озарения», «Советы Уилсона», «Морг»
+
+#### Scenario: Deletion verbs are consistent
+- **WHEN** reading `common.delete`, `taskDetail.delete`, `category.deleteLabel`
+- **THEN** the values are «В морг», «В морг», «Закрыть отделение»
+
+### Requirement: Accessibility strings are not themed (FR4)
+
+`house.json` SHALL NOT override accessibility-only keys: `alert.*`, `attachment.list.*`, `attachment.lightbox.dialogLabel`, `attachment.lightbox.close`, `taskEdit.checkItemMark`, `taskEdit.checkItemUnmark`, `taskEdit.checkItemDelete`, `taskEdit.dragChecklist`, `taskEdit.checklistBadgeAriaLabel`, `taskEdit.attachmentsBadgeAriaLabel`, `settings.menuOrderDragHandle`, `settings.menuOrderToggle`, `settings.settingsAriaLabel`, `settings.loginAriaLabel`, `settings.avatarAlt`, `sync.ariaLabel`, `filter.closeSidebar`. Exception: `deleted.restoreAriaLabel` MAY be themed because the glossary verb is the clearest action name.
+
+#### Scenario: Aria keys absent from locale
+- **WHEN** `house.json` is flattened
+- **THEN** none of the listed accessibility keys are present
+
+### Requirement: Data-repair and configuration strings are not themed (FR5)
+
+`house.json` SHALL NOT override: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlertTitle`, `repeat.invalidRuleAlertMessage`, `repeat.invalidRuleAlertFix`, `auth.*`, `sidebar.*`.
+
+#### Scenario: Repair-instruction keys absent from locale
+- **WHEN** `house.json` is flattened
+- **THEN** no key from the listed namespaces is present
+
+### Requirement: Placeholder and plural parity with base (FR6)
+
+Every overridden key SHALL contain exactly the same set of `{{placeholder}}` names as its base key, and plural/ordinal suffix variants SHALL only exist where the base key has them.
+
+#### Scenario: Placeholders preserved
+- **WHEN** an overridden key's base value contains placeholders (e.g. `deleted.purgeConfirmCount`)
+- **THEN** the override contains the identical placeholder set
+
+### Requirement: Locale metadata preserved (FR7)
+
+`_meta` SHALL remain `{ code: "house", name: "Dr. House", nativeName: "Доктор Хаус", baseLanguage: "ru", emoji: "🏥" }`.
+
+#### Scenario: Metadata intact
+- **WHEN** `house.json` is loaded
+- **THEN** `_meta.code` is `house` and `_meta.baseLanguage` is `ru`
+
+### Requirement: Formal capitalized address (FR8)
+
+Strings addressing the user directly SHALL use capitalized «Вы»/«Ваш» forms (e.g. «Что Вас осенило?..», «останутся у Вас на устройстве»).
+
+#### Scenario: Capitalized address in user-facing phrases
+- **WHEN** any override contains a direct address pronoun
+- **THEN** it is written as «Вы»/«Вас»/«Ваш» with a capital letter
+
+### Requirement: Normative phrase inventory (FR1–FR3)
+
+`house.json` SHALL consist of exactly the `_meta` object and the following overrides:

+# Capability: i18n-check
+
+## Purpose
+
+Automated locale consistency checking: flatten locale JSON, scan source files for key usage, detect undefined keys, unused keys, parity violations, override orphans, duplicate values, and whitelist self-validation. Provides CLI interface for standalone and CI usage.
+
+## Requirements
+
+### Requirement: Flatten locale JSON and normalize plural keys
+
+The system SHALL flatten nested locale JSON objects into dot-separated key-value maps. The system SHALL normalize i18next plural suffixes (`_one`, `_two`, `_few`, `_many`, `_other`, `_zero`) and ordinal suffixes (`_ordinal_one`, etc.) to produce base keys for comparison.
+
+#### Scenario: Nested JSON is flattened correctly
+- **WHEN** a locale JSON contains `{ "task": { "cancel": "Cancel" } }`
+- **THEN** the flat map contains key `"task.cancel"` with value `"Cancel"`
+
+#### Scenario: Plural suffix is stripped to produce base key
+- **WHEN** a flat key is `"repeat.everyNDays_few"`
+- **THEN** the base key is `"repeat.everyNDays"`
+
+#### Scenario: Ordinal suffix is stripped to produce base key
+- **WHEN** a flat key is `"repeat.yearlyDate_ordinal_two"`
+- **THEN** the base key is `"repeat.yearlyDate"`
+
+#### Scenario: Underscore in key name is preserved
+- **WHEN** a flat key is `"filter.focused_goals"`
+- **THEN** the base key is `"filter.focused_goals"` (unchanged, since `_goals` is not a CLDR plural form)
+
+### Requirement: Scan source files for literal keys and dynamic prefixes
+
+The system SHALL scan TypeScript/TSX source files and extract:
+1. Literal keys: dot-separated identifiers in quotes/backticks that match a top-level namespace from `en.json`
+2. Dynamic prefixes: template literal content before `${...}` that contains at least one dot and matches a top-level namespace
+
+The system SHALL classify keys by file type (production vs test) based on path patterns.
+
+The system SHALL NOT include keys from the i18n-check tool's own test fixtures in production scan results. Test fixtures SHALL use synthetic namespaces (e.g., `fx.`) that do not exist in `en.json`.
+
+#### Scenario: Literal key in production file is detected
+- **WHEN** a production file contains `t("task.cancel")`
+- **THEN** `"task.cancel"` appears in `literalKeys` and NOT in `literalKeysTestOnly`
+
+#### Scenario: Literal key only in test file is flagged as test-only
+- **WHEN** a test file contains `"task.cancel"` and no production file references it
+- **THEN** `"task.cancel"` appears in `literalKeysTestOnly`
+
+#### Scenario: Dynamic prefix is extracted from template literal
+- **WHEN** a source file contains `` t(`goal.status.${status}`) ``
+- **THEN** `"goal.status."` appears in `dynamicPrefixes`
+
+#### Scenario: Non-i18n dotted string is filtered out by namespace check
+- **WHEN** a source file contains `"package.json"` and `"package"` is not a top-level namespace in `en.json`
+- **THEN** `"package.json"` is NOT included in scan results
+
+#### Scenario: Test fixture with synthetic namespace is excluded
+- **WHEN** a test file contains `"fx.monthAndDay"` and `"fx"` is not a top-level namespace in `en.json`
+- **THEN** `"fx.monthAndDay"` is NOT included in scan results
+
+### Requirement: Detect undefined keys (FR1)
+
+The system SHALL report an error of kind `undefined` for every literal key found in production source code that does not exist as a base key in `en.json` and is not covered by a whitelist pattern.
+
+#### Scenario: Key used in code but missing from en.json
+- **WHEN** production code references `"sync.alert.repeat_rule_reset"` and this base key is absent from `en.json`
+- **THEN** an error `{ kind: "undefined", key: "sync.alert.repeat_rule_reset" }` is reported
+
+#### Scenario: Key only in test file does not trigger undefined error
+- **WHEN** `"fake.test.key"` appears only in a test file and is absent from `en.json`
+- **THEN** no `undefined` error is reported for this key
+
+#### Scenario: Key referenced via messageKey variable is covered by whitelist
+- **WHEN** `healingRules.ts` assigns `messageKey: "sync.alert.repeat_rule_reset"` and the whitelist contains a pattern matching `sync.alert.*`
+- **THEN** no `undefined` error is reported for this key (assuming the key exists in `en.json`)
+
+### Requirement: Detect unused keys (FR2)
+
+The system SHALL report an error of kind `unused` for every base key in `en.json` that is:
+- Not found as a literal key in any production source file (keys found ONLY in test files do not count as "found")
+- Not matched by any dynamic prefix (with conservative rest-character validation)
+- Not matched by any whitelist pattern
+
+Dynamic prefix matching for dotted prefixes (ending with `.`) SHALL require the prefix to contain >= 2 named segments (i.e., at least one dot before the trailing dot). Single-segment dotted prefixes (e.g., `repeat.`) SHALL NOT protect keys from being reported as unused — their enum values must be covered by explicit whitelist entries instead.
+
+Non-dotted prefixes SHALL continue to match when the rest is digits-only (e.g., `repeat.month` protects `repeat.month7`).
+
+Keys found ONLY in test files SHALL be reported as unused with detail "found ONLY in tests — likely a dead key".
+
+#### Scenario: Key in en.json not referenced anywhere
+- **WHEN** `en.json` contains key `"nav.oldFeature"` and no source file references it
+- **THEN** an error `{ kind: "unused", key: "nav.oldFeature" }` is reported
+
+#### Scenario: Key matched by multi-segment dynamic prefix is not reported unused
+- **WHEN** `en.json` contains `"goal.status.in_progress"` and source has `` `goal.status.${status}` ``
+- **THEN** no `unused` error is reported (prefix `"goal.status."` has 2 segments, rest `"in_progress"` has no dots)
+
+#### Scenario: Single-segment dotted prefix does NOT protect keys
+- **WHEN** `en.json` contains `"repeat.frequency"` and source has `` `repeat.${freq}` `` producing prefix `"repeat."`
+- **THEN** an `unused` error IS reported for `"repeat.frequency"` (prefix has only 1 named segment)
+
+#### Scenario: Key with shared non-dotted prefix but non-digit rest is still reported
+- **WHEN** `en.json` contains `"repeat.monthAndDay"` and prefix `"repeat.month"` exists from `` `repeat.month${m}` ``
+- **THEN** an `unused` error IS reported (rest `"AndDay"` is not digits-only)
+
+#### Scenario: Whitelisted key is not reported unused regardless of prefix rules
+- **WHEN** `en.json` contains `"repeat.daily"` and whitelist has a `oneOf("repeat.", ["daily", ...])` pattern
+- **THEN** no `unused` error is reported
+
+#### Scenario: Key found only in test files is reported as unused
+- **WHEN** `en.json` contains `"repeat.monthAndDay"` and it appears only in test files (not in production code)
+- **THEN** an error `{ kind: "unused", key: "repeat.monthAndDay", detail: "found ONLY in tests — likely a dead key" }` is reported
+
+### Requirement: Detect locale parity violations (FR3)
+
+The system SHALL report an error of kind `parity` for every base key that exists in `en.json` but not in `ru.json`, or vice versa.
+
+#### Scenario: Key in en missing from ru
+- **WHEN** base key `"feature.new"` exists in `en.json` but not in `ru.json`
+- **THEN** an error `{ kind: "parity", key: "feature.new", detail: "present in en, missing in ru" }` is reported
+
+#### Scenario: Key in ru missing from en
+- **WHEN** base key `"legacy.removed"` exists in `ru.json` but not in `en.json`
+- **THEN** an error `{ kind: "parity", key: "legacy.removed", detail: "present in ru, missing in en" }` is reported
+
+### Requirement: Detect override orphan keys (FR4)
+
+The system SHALL report an error of kind `override-orphans` for every base key in an override locale (where `_meta.baseLanguage` differs from locale code) that does not exist in its base locale, excluding `_meta.*` keys.
+
+#### Scenario: Override key absent from base locale
+- **WHEN** `house.json` has `_meta.baseLanguage: "ru"` and contains key `"repeat.day1"` which is absent from `ru.json`
+- **THEN** an error `{ kind: "override-orphans", key: "repeat.day1" }` is reported
+
+#### Scenario: _meta keys are excluded from orphan check
+- **WHEN** `house.json` contains `"_meta.baseLanguage"` and `"_meta.name"`
+- **THEN** no `override-orphans` error is reported for these keys
+
+### Requirement: Report duplicate values (FR5)
+
+The system SHALL always report groups of keys that have identical values in both `en.json` and `ru.json` as candidates for deduplication, UNLESS all keys in the group are covered by a duplicate-whitelist entry. This report is printed on every run (informational, does not cause a non-zero exit code).
+
+Groups where every key matches a duplicate-whitelist pattern SHALL be suppressed from the output.
+
+#### Scenario: Keys with same value in both locales are grouped
+- **WHEN** `en.json` has `"task.cancel": "Cancel"` and `"goal.cancel": "Cancel"`, and `ru.json` has both as `"Отмена"`
+- **AND** neither key is in the duplicate whitelist
+- **THEN** a duplicate group `["task.cancel", "goal.cancel"]` is reported
+
+#### Scenario: Keys with same en value but different ru values are not grouped
+- **WHEN** `en.json` has `"repeat.month4": "April"` and `"repeat.monthGenitive4": "April"`, but `ru.json` has `"апрель"` and `"апреля"`
+- **THEN** no duplicate group is reported for these keys
+
+#### Scenario: Whitelisted duplicate group is suppressed
+- **WHEN** `en.json` has `"box.inbox": "Inbox"` and `"filter.inbox": "Inbox"` with identical RU values
+- **AND** both keys match a duplicate-whitelist pattern
+- **THEN** no duplicate group is reported for these keys
+
+### Requirement: Duplicate whitelist for intentional duplicates
+
+The system SHALL support a duplicate-value whitelist — a set of key patterns that are expected to have duplicate values across namespaces. The whitelist SHALL be defined in `whitelist.ts` alongside the existing unused-key whitelist.
+
+Whitelisted categories:
+1. **Domain navigation terms**: keys across `box`, `section`, `filter`, `search`, `deleted`, `task`, `repeat`, `goalFilter`, `idea.pageName`, `memo.pageName`, `settings.sections` that share values for the same domain concept
+2. **Semantic pairs**: keys with different UI roles (display label vs ariaLabel, indicator vs legend, button label vs type label) that happen to share the same text
+
+#### Scenario: Domain term duplicate is whitelisted
+- **WHEN** `box.inbox` and `filter.inbox` both have value "Inbox"/"Входящие"
+- **THEN** both keys match a duplicate-whitelist pattern and the group is suppressed
+
+#### Scenario: Semantic pair duplicate is whitelisted
+- **WHEN** `settings.name` and `settings.settingsAriaLabel` both have value "Settings"/"Настройки"
+- **THEN** both keys match a duplicate-whitelist pattern and the group is suppressed
+
+#### Scenario: Non-whitelisted duplicate is still reported
+- **WHEN** two keys have identical values but are not in the duplicate whitelist
+- **THEN** the duplicate group is reported as before
+
+### Requirement: Duplicate whitelist self-validation
+
+The system SHALL verify that every duplicate-whitelist pattern matches at least one existing key in `en.json`. A pattern that matches zero keys SHALL be reported as an error, consistent with the existing unused-key whitelist validation (FR8).
+
+#### Scenario: Stale duplicate-whitelist pattern triggers error
+- **WHEN** a duplicate-whitelist pattern matches zero keys in `en.json`
+- **THEN** an error is reported indicating the whitelist entry is stale
+
+### Requirement: Whitelist self-validation (FR8)
+
+The system SHALL verify that every whitelist pattern matches at least one existing key in `en.json`. A pattern that matches zero keys SHALL be reported as an error.
+
+#### Scenario: Stale whitelist pattern triggers error
+- **WHEN** a whitelist pattern `/^legacy\./` matches zero keys in `en.json`
+- **THEN** an error is reported indicating the whitelist entry is stale
+
+#### Scenario: sync.alert whitelist pattern is valid
+- **WHEN** the whitelist contains pattern `^sync\.alert\.` and `en.json` contains `sync.alert.repeat_rule_reset`
+- **THEN** no stale whitelist error is reported
+
+### Requirement: CI enforcement of locale consistency
+
+The CI pipeline SHALL run `i18n:check` before building. Any `undefined`, `unused`, `parity`, or `override-orphans` error SHALL cause the CI job to fail, preventing deployment of code with locale drift.
+
+#### Scenario: CI blocks deploy when undefined key exists
+- **WHEN** a PR introduces code referencing a key not present in `en.json`
+- **AND** CI runs `i18n:check`
+- **THEN** the CI job exits with code 1 and the PR cannot be merged
+
+#### Scenario: CI passes when all locale checks are clean
+- **WHEN** all locale keys are consistent
+- **AND** CI runs `i18n:check`
+- **THEN** the CI job exits with code 0
+
+### Requirement: CLI interface (UX1-UX3)
+
+The system SHALL provide a CLI entrypoint that:
+- Exits with code 1 when any check error is found
+- Exits with code 0 when no errors are found
+- Prints each error as `[kind] key — detail`
+- Prints summary count on failure
+- Prints `i18n-check: OK` on success
+- Always prints the duplicates report (informational section after errors)
+
+#### Scenario: Errors found — exit code 1
+- **WHEN** the check finds 3 errors
+- **THEN** CLI prints 3 error lines, a summary `i18n-check: 3 errors`, and exits with code 1
+
+#### Scenario: No errors — exit code 0
+- **WHEN** the check finds 0 errors
+- **THEN** CLI prints `i18n-check: OK` and exits with code 0
+
+### Requirement: Test fixture isolation from production scan
+
+Fixture strings in the i18n-check tool's own test files SHALL NOT be able to
+affect real-project check results. Specifically, no string fixture in
+`src/test/i18n-check/*.test.ts` may coincide (after plural/ordinal
+normalization via `toBaseKey`) with a key present in `en.json`. Fixture
+strings under real namespaces that do NOT correspond to existing keys are
+permitted (e.g., negative-test fixtures like `"repeat.frequency"` for a
+deleted key), because `checkUnused` treats test-only literals as unused
+candidates and `checkUndefined` ignores test-only literals — such fixtures
+cannot shield or falsely flag anything.
+
+Exception: fixtures that verify real WHITELIST behavior (e.g., `isWhitelisted("repeat.daily")`)
+are permitted to use live keys, documented in an explicit allow-list with justification.
+
+#### Scenario: Fixture coinciding with a live key is forbidden
+- **WHEN** `en.json` contains `task.cancel` and a tool test file contains the string `"task.cancel"`
+- **THEN** the fixture-isolation test fails, naming the file and the offending string
+
+#### Scenario: Fixture under a real namespace but absent from en.json is allowed
+- **WHEN** `en.json` does not contain `repeat.frequency` and a tool test file contains the string `"repeat.frequency"`
+- **THEN** the fixture-isolation test passes
+
+#### Scenario: Whitelisted fixture for WHITELIST verification is allowed
+- **WHEN** a test verifies `isWhitelisted("repeat.daily")` against the real WHITELIST
+- **THEN** `"repeat.daily"` is permitted via the explicit allow-list with a comment justifying its presence

+### Requirement: Common namespace for shared UI labels
+
+Locale files SHALL contain a `common` top-level namespace with shared UI labels that are used identically across multiple domain namespaces. Components SHALL reference `common.*` keys instead of duplicating the same label under each domain namespace.
+
+The `common` namespace SHALL include at minimum: `cancel`, `back`, `delete`, `close`, `next`, `save`, `loading`, `name`, `taskCount`, `details`, `attachments`.
+
+#### Scenario: Component uses common.cancel instead of domain-specific key

+- **AND** `EntityDetailLayout` consumers (`ContextDetailPage`, `CategoryDetailPage`) SHALL pass `"common.saveName"` via `i18nKeys.saveName`
+
+### Requirement: Dialect locales inherit base language plural rules
+
+Dialect locales (where `_meta.baseLanguage` differs from the locale code) SHALL select CLDR plural forms using the plural rules of their base language. Dialect codes are not valid BCP 47 languages, so `Intl.PluralRules` would otherwise degrade them to root rules where every count maps to `other`, making plural overrides in dialect files unreachable. The rule applies both to keys overridden in the dialect file and to keys resolved via fallback. # implements FR10 of rework-house-locale
+
+#### Scenario: Dialect plural override uses base language forms
+- **WHEN** translating a key overridden in "house" (baseLanguage "ru") with count 21
+- **THEN** the `_one` form of the house override is used (e.g. «21 пациент»)
+
+#### Scenario: Dialect fallback keys keep base language plural forms
+- **WHEN** translating a key absent from "house" (e.g. `repeat.intervalDays`) with count 3 in locale "house"
+- **THEN** the Russian `_few` form is used («Интервал: 3 дня»)
+
+#### Scenario: Base locales are unaffected
+- **WHEN** translating a plural key in locale "ru" or "en"
+- **THEN** plural forms are selected by that locale's own rules
+
 ### Requirement: Pluralization follows CLDR rules

+# Capability: project-locales
+
+## Purpose
+
+Content rules for the twin GTD-terminology dialect locales `packages/client/src/locales/en-project.json` (base `en`) and `packages/client/src/locales/ru-project.json` (base `ru`): goal → project / «цель» → «проект», nothing else.
+
+## Requirements
+
+### Requirement: Locales contain only differing overrides (FR1)
+
+`en-project.json` and `ru-project.json` SHALL contain only keys whose values differ from the corresponding base (`en.json` / `ru.json`) values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in the base file (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of each dialect file is compared with its base file
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `en-project.json` or `ru-project.json`
+
+### Requirement: Override set is exactly the term-mentioning keys (FR2)
+
+The override set of each dialect SHALL be exactly the base keys whose value matches the term regex — `/\bgoals?\b/i` for `en.json`, `/(?<![а-яёА-ЯЁ])цел(ь|ью|и|ей|ям|ями|ях)(?![а-яё])/iu` for `ru.json` — as enumerated by the normative inventories below. The Russian regex uses Cyrillic-aware lookaround boundaries because JavaScript `\b` is ASCII-only and never matches around Cyrillic (matching the existing `LOWERCASE_ADDRESS_REGEX` convention in `locale_content.helpers.ts`). Placeholder names such as `{{goalName}}` do not match (word boundary) and SHALL NOT trigger an override by themselves.
+
+#### Scenario: Inventory matches the derivation rule
+- **WHEN** the term regex is applied to every value of the base file
+- **THEN** the set of matching keys equals the key set of the normative inventory for that dialect
+
+#### Scenario: Dialect file matches the inventory exactly
+- **WHEN** each dialect file is flattened (excluding `_meta`)
+- **THEN** its key set equals the normative inventory — no missing and no extra keys
+
+### Requirement: Overrides substitute the term and nothing else (FR3)
+
+Every override SHALL differ from its base value only by replacing goal → project / «цель» → «проект», including required grammatical adjustments in Russian (masculine gender agreement and plural forms «проект / проекта / проектов»). No override value SHALL match the term regex of its base language. No other wording, punctuation, or tone changes are allowed.
+
+#### Scenario: No goal terminology survives in overrides
+- **WHEN** the base-language term regex is applied to every override value
+- **THEN** there are zero matches across both dialect files
+
+#### Scenario: Russian gender agreement
+- **WHEN** reading `goal.notFound`, `goal.empty`, `commandBar.placeholder.goal` in `ru-project.json`
+- **THEN** the values are «Проект не найден», «Нет ни одного проекта», «Новый проект...»
+
+### Requirement: Placeholder and plural parity with base (FR4)
+
+Every overridden key SHALL preserve the interpolation placeholders (`{{count}}`, `{{goalName}}`, …) and the plural-suffix structure of its base key (`_one/_other` for en, `_one/_few/_many` for ru).
+
+#### Scenario: Placeholders preserved
+- **WHEN** placeholders of every override are compared with its base value
+- **THEN** the placeholder multisets are identical
+
+#### Scenario: Plural suffix structure preserved
+- **WHEN** the plural-suffixed key groups of each dialect are compared with base
+- **THEN** every overridden plural group contains exactly the base suffix set
+
+### Requirement: Locale metadata (FR5)
+
+`_meta` SHALL be exactly `{ code: "en-project", name: "English (project)", nativeName: "English (project)", baseLanguage: "en", emoji: "🇺🇸" }` for `en-project.json` and `{ code: "ru-project", name: "Russian (project)", nativeName: "Русский (проект)", baseLanguage: "ru", emoji: "🇷🇺" }` for `ru-project.json`.
+
+#### Scenario: Metadata exactness
+- **WHEN** reading `_meta` of both dialect files
+- **THEN** every field equals the values above, and `code` matches the filename
+
+### Requirement: Accessibility strings follow the same substitution (FR7)
+
+Accessibility strings whose base value mentions the term (e.g. `goal.drag`, `goal.editName`) SHALL be overridden with the same terminology substitution. No no-theming zone applies: substitution is terminology-only and never degrades the functional meaning of an accessible name.
+
+#### Scenario: Accessible names substituted
+- **WHEN** reading `goal.drag` and `goal.editName` in both dialects
+- **THEN** the values are "Drag project" / "Edit project" and «Перетащить проект» / «Редактировать проект»
+
+### Requirement: Normative inventory — en-project (FR2, FR3)
+
+`en-project.json` SHALL contain exactly the following 26 overrides.

+# Capability: startrek-locale
+
+## Purpose
+
+Content rules for the Star Trek dialect locale (`packages/client/src/locales/startrek.json`, base `ru`).
+
+## Requirements
+
+### Requirement: Locale contains only differing overrides (FR1)
+
+`startrek.json` SHALL contain only keys whose values differ from the corresponding `ru.json` values. Keys with values identical to base SHALL be absent (covered by fallback). Every non-`_meta` key SHALL exist in `ru.json` (no orphans).
+
+#### Scenario: No redundant overrides
+- **WHEN** every non-`_meta` key of `startrek.json` is compared with `ru.json`
+- **THEN** no key has a value identical to its base value
+
+#### Scenario: No orphan keys
+- **WHEN** `i18n-check` runs
+- **THEN** no `override-orphans` errors are reported for `startrek.json`
+
+### Requirement: Themed strings follow the entity glossary (FR2, FR3)
+
+All themed strings SHALL use the glossary of design.md D1 (idea = «новый мир», goal = «миссия», task = «задание», checklist item = «директива», category = «отсек», box = «курс», attachment = «голозапись», memo = «Журнал капитана», deleted = «За бортом») and the verb system of D2 (delete = «за борт», delete idea = «покинуть орбиту», delete structural = «задраить», restore = «поднять на борт», purge = «отпустить в дрейф», hide = «маскировка», move = «проложить другой курс»).
+
+#### Scenario: Entity page names match glossary
+- **WHEN** reading `goal.pageName`, `idea.pageName`, `memo.pageName`, `deleted.pageName`
+- **THEN** the values are «Миссии», «Новые миры», «Журнал капитана», «За бортом»
+
+#### Scenario: Deletion verbs are consistent
+- **WHEN** reading `common.delete`, `taskDetail.delete`, `category.deleteLabel`, `idea.deleteLabel`
+- **THEN** the values are «За борт», «За борт», «Задраить отсек», «Покинуть орбиту»
+
+### Requirement: Accessibility strings are not themed (FR4)
+
+`startrek.json` SHALL NOT override accessibility-only keys: `alert.*`, `attachment.list.*`, `attachment.lightbox.dialogLabel`, `attachment.lightbox.close`, `taskEdit.checkItemMark`, `taskEdit.checkItemUnmark`, `taskEdit.checkItemDelete`, `taskEdit.dragChecklist`, `taskEdit.checklistBadgeAriaLabel`, `taskEdit.attachmentsBadgeAriaLabel`, `settings.menuOrderDragHandle`, `settings.menuOrderToggle`, `settings.settingsAriaLabel`, `settings.loginAriaLabel`, `settings.avatarAlt`, `sync.ariaLabel`, `filter.closeSidebar`. Exception: `deleted.restoreAriaLabel` MAY be themed because the glossary verb is the clearest action name.
+
+#### Scenario: Aria keys absent from locale
+- **WHEN** `startrek.json` is flattened
+- **THEN** none of the listed accessibility keys are present
+
+### Requirement: Data-repair and configuration strings are not themed (FR5)
+
+`startrek.json` SHALL NOT override: `sync.alert.*`, `settings.server.*`, `projectPausedDialog.*`, `repeat.ruleNotRecognized`, `repeat.invalidRuleAlertTitle`, `repeat.invalidRuleAlertMessage`, `repeat.invalidRuleAlertFix`, `auth.*`, `sidebar.*`.
+
+#### Scenario: Repair-instruction keys absent from locale
+- **WHEN** `startrek.json` is flattened
+- **THEN** no key from the listed namespaces is present
+
+### Requirement: Placeholder and plural parity with base (FR6)
+
+Every overridden key SHALL contain exactly the same set of `{{placeholder}}` names as its base key, and plural/ordinal suffix variants SHALL only exist where the base key has them.
+
+#### Scenario: Placeholders preserved
+- **WHEN** an overridden key's base value contains placeholders (e.g. `deleted.purgeConfirmCount`)
+- **THEN** the override contains the identical placeholder set
+
+### Requirement: Locale metadata (FR7)
+
+`_meta` SHALL be `{ code: "startrek", name: "Star Trek", nativeName: "Звёздный путь", baseLanguage: "ru", emoji: "🖖" }`.
+
+#### Scenario: Metadata exact
+- **WHEN** `startrek.json` is loaded
+- **THEN** `_meta.code` is `startrek`, `_meta.baseLanguage` is `ru`, and `_meta.emoji` is «🖖»
+
+### Requirement: Crew-to-captain voice and address register (FR8)
+
+The locale voice SHALL be the crew addressing the user as «капитан» (lowercase mid-sentence). Where overrides address the user directly, they SHALL use either the «капитан» address or capitalized «Вы»/«Ваш» forms. Character cameo lines appear only in empty states, statuses, and error texts — never on action buttons.
+
+#### Scenario: Capitalized address in user-facing phrases
+- **WHEN** any override contains a direct address pronoun
+- **THEN** it is written as «Вы»/«Вас»/«Ваш» with a capital letter
+
+#### Scenario: Captain address is lowercase
+- **WHEN** any override contains the word «капитан» as an address mid-sentence
+- **THEN** it is written in lowercase
+
+### Requirement: Sync status strings stay short (FR9)
+
+No themed `sync.*` string SHALL exceed its `ru.json` counterpart by more than 10 characters.
+
+#### Scenario: Length budget respected
+- **WHEN** each themed `sync.*` value is compared with its base value
+- **THEN** `themed.length <= base.length + 10`
+
+### Requirement: Normative phrase inventory (FR1–FR3)
+
+`startrek.json` SHALL consist of exactly the `_meta` object and the following overrides:

+Feature: Project locales content
+  Implements change add-project-locales.
+  The project dialects are terminology-only overrides of their base locales:
+  "en-project" over "en" and "ru-project" over "ru", replacing goal → project
+  and «цель» → «проект» and nothing else. No theming, no voice, no glossary
+  beyond the single term.
+
+  Background:
+    Given the project dialect files and their base locales are flattened
+
+  @add-project-locales @FR1
+  Scenario Outline: Dialect carries only phrases that differ from the base
+    Then no <dialect> override has a value identical to its base value
+
+    Examples:
+      | dialect    |
+      | en-project |
+      | ru-project |
+
+  @add-project-locales @FR1
+  Scenario Outline: Every override exists in the base locale

+      | en-project |
+      | ru-project |
+
+  @add-project-locales @FR2
+  Scenario Outline: Override set is derived from the term-mentioning base keys
+    When the term regex is applied to every value of the base locale
+    Then the set of matching keys equals the normative inventory of <dialect>
+
+    Examples:
+      | dialect    |
+      | en-project |
+      | ru-project |
+
+  @add-project-locales @FR2 @FR3
+  Scenario Outline: Dialect content equals the normative inventory exactly
+    Then the <dialect> overrides equal the normative inventory exactly

+    Examples:
+      | dialect    |
+      | en-project |
+      | ru-project |
+
+  @add-project-locales @FR3
+  Scenario Outline: No goal terminology survives in overrides
+    Then no <dialect> override value matches the base-language term regex
+
+    Examples:
+      | dialect    |
+      | en-project |
+      | ru-project |
+
+  @add-project-locales @FR3
+  Scenario: Russian overrides use masculine gender agreement
+    Then the ru-project dialect values are:
+      | key                         | value                |
+      | goal.notFound               | Проект не найден     |
+      | goal.empty                  | Нет ни одного проекта |
+      | commandBar.placeholder.goal | Новый проект...      |
+
+  @add-project-locales @FR4
+  Scenario Outline: Overrides keep the placeholders of their base phrases
+    Then every <dialect> override contains exactly the placeholders of its base value

+Feature: Star Trek locale content
+  Implements change add-startrek-locale.
+  The Star Trek dialect locale is a minimal themed override of the Russian
+  base locale: the app is the starship Enterprise and the user is its captain.
+  One starship glossary, no redundant keys, no jokes where operability matters.
+
+  Background:
+    Given the "startrek" and "ru" locale files are flattened
+
+  @add-startrek-locale @FR1
+  Scenario: Locale carries only phrases that differ from the base
+    Then no startrek override has a value identical to its base value
+
+  @add-startrek-locale @FR1
+  Scenario: Every override exists in the base locale
+    Then every startrek override key exists in the base locale
+
+  @add-startrek-locale @FR2
+  Scenario: Entity pages follow the starship glossary
+    Then the startrek locale values are:
+      | key              | value           |
+      | goal.pageName    | Миссии          |
+      | idea.pageName    | Новые миры      |
+      | memo.pageName    | Журнал капитана |
+      | deleted.pageName | За бортом       |
+
+  @add-startrek-locale @FR3
+  Scenario: Deletion verbs follow the verb system
+    Then the startrek locale values are:
+      | key                  | value          |
+      | common.delete        | За борт        |
+      | taskDetail.delete    | За борт        |
+      | category.deleteLabel | Задраить отсек |
+      | idea.deleteLabel     | Покинуть орбиту |
+
+  @add-startrek-locale @FR4
+  Scenario: Accessibility strings keep their base wording
+    Then no accessibility-only key is overridden
+
+  @add-startrek-locale @FR5
+  Scenario: Data-repair and configuration instructions keep their base wording
+    Then no data-repair or configuration key is overridden
+
+  @add-startrek-locale @FR6
+  Scenario: Overrides keep the placeholders of their base phrases
+    Then every override contains exactly the placeholders of its base value
+
+  @add-startrek-locale @FR7
+  Scenario: Locale metadata identifies the dialect
+    Then startrek locale metadata declares code "startrek" with base language "ru" and emoji "🖖"
+
+  @add-startrek-locale @FR8
+  Scenario: The user is addressed with capitalized Вы
+    Then no override contains a lowercase direct-address pronoun
+
+  @add-startrek-locale @FR8
+  Scenario: The captain address stays lowercase mid-sentence
+    Then every override addressing «капитан» mid-sentence writes it in lowercase
+
+  @add-startrek-locale @FR9
+  Scenario: Sync status strings stay within the length budget
+    Then no themed sync string exceeds its base value by more than 10 characters
+
+  @add-startrek-locale @FR1 @FR2 @FR3
+  Scenario: Locale content equals the normative inventory
+    Then the startrek overrides equal the normative phrase inventory exactly
