# Tasks: Platform Localization v1 (DE/EN)

**Input**: Design documents from `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/`  
**Prerequisites**: `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/plan.md` (required), `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/spec.md` (required), `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/checklists/requirements.md` (required), `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/research.md`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/data-model.md`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/contracts/locale-resolution-and-translation-governance.logical.openapi.yaml`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/quickstart.md`

**Tests**: Required (Pest) for all runtime behavior changes. Keep proof in focused `Unit` plus `Feature` lanes only, using the targeted Sail commands already captured in the feature spec, plan, and quickstart artifacts.

## Test Governance Notes

- Lane assignment: `fast-feedback` and `confidence` are the narrowest sufficient proof for locale precedence, request-time application, translated core surfaces, feedback localization, fallback safety, authorization invariance, and invariant machine-format behavior.
- Keep new coverage inside `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Unit/Localization/`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Filament/Localization/`; do not widen this slice into browser or heavy-governance families.
- Reuse existing user, workspace, membership, workspace-setting, and representative governance surface fixtures. Any new helper must stay opt-in and cheap by default.
- If one late surface remains English-only for a bounded reason, record it as `document-in-feature` in close-out instead of widening scope into a broader localization program.

## Scope Control Notes

- Keep implementation inside one locale resolver contract, one workspace-bound user preference path, one workspace default path, current panel/auth/Livewire request application, first-wave translation coverage for shell plus high-signal governance surfaces, and invariant export/audit/raw payload behavior.
- Do not add website localization, more than two locales, a generic preferences framework, a second persisted preference store for system `PlatformUser` actors, public documentation translation, or broad email-template localization.

---

## Phase 1: Setup (Shared Infrastructure)

**Purpose**: Lock the bounded slice, translation inventory, and validation plan before runtime edits begin.

- [x] T001 Review the bounded slice, explicit non-goals, and outcome class in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/spec.md`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/plan.md`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/checklists/requirements.md`
- [x] T002 [P] Review locale precedence, persistence ownership, and invariance boundaries in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/research.md`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/data-model.md`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/contracts/locale-resolution-and-translation-governance.logical.openapi.yaml`
- [x] T003 [P] Confirm the focused Sail/Pest proof commands and manual smoke expectations in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/quickstart.md`

---

## Phase 2: Foundational (Blocking Prerequisites)

**Purpose**: Add the shared locale primitives that every user story depends on.

**⚠️ CRITICAL**: No user story work should begin until this phase is complete.

- [x] T004 [P] Add the supported-locale allowlist, precedence evaluation, and fallback behavior in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Services/Localization/LocaleResolver.php`
- [x] T005 [P] Add the personal locale preference field and model support in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/database/migrations/*_add_preferred_locale_to_users_table.php` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Models/User.php`
- [x] T006 [P] Register the workspace default locale definition and persistence path in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Support/Settings/SettingsRegistry.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Services/Settings/SettingsResolver.php`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Services/Settings/SettingsWriter.php`
- [x] T007 Thread locale application through `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/bootstrap/app.php`, a new `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Http/Middleware/ApplyResolvedLocale.php`, and the current panel providers in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Providers/Filament/`, with explicit override plus system default only on the system panel

**Checkpoint**: Foundation ready. Locale precedence, persistence, and request-time application now exist without any page-local language logic.

---

## Phase 3: User Story 1 - Choose and inherit language predictably (Priority: P1) 🎯 MVP

**Goal**: Let users inherit workspace default language, override it personally, and apply a temporary explicit override from the current shell.

**Independent Test**: Set workspace default locale, set or clear a personal preference, apply or clear an explicit override, and verify the effective locale on normal, auth, system-panel, and Livewire-backed panel requests, with the system panel using explicit override plus system default only.

### Tests for User Story 1

- [x] T008 [P] [US1] Add unit and feature coverage for precedence ordering, unsupported-locale fallback, reset-to-inherited behavior, auth and system-panel rendering, wrong-plane or non-member 404, member-but-no-capability 403, system-panel explicit-override plus system-default behavior, and Livewire continuity in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Unit/Localization/LocaleResolverTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/AuthAndSystemSurfaceLocalizationTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/LocalePreferenceFlowTest.php`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/WorkspaceDefaultLocaleTest.php`

### Implementation for User Story 1

- [x] T009 [US1] Add the user-facing locale control to the existing shared shell surface in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/resources/views/filament/partials/context-bar.blade.php` and any required panel-provider wiring in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Providers/Filament/`
- [x] T010 [US1] Add the workspace default locale field to `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/Pages/Settings/WorkspaceSettings.php` using the current workspace settings save and audit path, including clear-to-inherit behavior back to the system default
- [x] T011 [US1] Localize shell and auth copy across `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/Pages/Auth/Login.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/System/Pages/Auth/Login.php`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/resources/views/filament/partials/context-bar.blade.php`

**Checkpoint**: User Story 1 is independently functional when language choice is deterministic and visible on the existing shell and settings surfaces.

---

## Phase 4: User Story 2 - Read core governance surfaces in the chosen language (Priority: P1)

**Goal**: Translate the first-wave governance surfaces so operators can work in English or German without mixed-language UI fragments.

**Independent Test**: Open the shell, tenant dashboard, system dashboard, Findings, Baseline Compare, and representative workspace or tenant management tables in both locales and verify headings, actions, empty states, and glossary terms align with the resolved locale.

### Tests for User Story 2

- [x] T012 [P] [US2] Add feature coverage for translated shell, tenant dashboard, system dashboard, and first-wave governance surface rendering and fallback behavior in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Filament/Localization/CoreGovernanceSurfaceLocalizationTest.php` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/TranslationFallbackGuardTest.php`

### Implementation for User Story 2

- [x] T013 [US2] Extract and add translation catalogs for shell, tenant and system dashboard surfaces, Findings, Baseline Compare, and representative management tables in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/lang/en/`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/lang/de/`, and the touched page/resource/view files
- [x] T014 [US2] Localize relative-time, date, and number formatting on the in-scope dashboard and governance surfaces in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/resources/views/filament/`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/`, and any related support presenters
- [x] T015 [US2] Keep search, filter, row-click, global-search, wrong-plane or non-member 404, member-but-no-capability 403, and scope semantics unchanged while translated labels render on the in-scope shell and governance surfaces

**Checkpoint**: User Story 2 is independently functional when the first-wave operator surfaces render coherent EN or DE copy without changing workflow semantics.

---

## Phase 5: User Story 3 - Localize feedback without changing machine truth (Priority: P1)

**Goal**: Make notifications, validation text, monitoring, alert, and operations feedback copy, plus customer-safe viewer chrome, locale-aware while exported and audited machine-readable content stays invariant.

**Independent Test**: Trigger representative notifications and validation messages, open a customer-safe review or report viewer, and confirm surrounding UI copy localizes while audit, export, and raw payload truth stays stable.

### Tests for User Story 3

- [x] T016 [P] [US3] Add feature coverage for localized notifications, validation and helper text, customer-safe viewer chrome, and machine-format invariance in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/LocalizedNotificationFormattingTest.php` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/MachineFormatInvarianceTest.php`

### Implementation for User Story 3

- [x] T017 [US3] Localize in-scope notifications, validation/system messages, and monitoring, alert, or operations feedback copy in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Livewire/`, and related view files
- [x] T018 [US3] Localize customer-safe review or report viewer shell copy while preserving invariant exports, audit values, IDs, and raw payload truth in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/Pages/Reviews/CustomerReviewWorkspace.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/app/Filament/Resources/TenantReviewResource.php`, and related viewer or widget views

**Checkpoint**: User Story 3 is independently functional when localized feedback and viewer shells coexist with unchanged machine-readable artifact truth.

---

## Phase 6: Polish & Cross-Cutting Concerns

**Purpose**: Run the narrow validation lanes, format touched files, and capture the feature-local close-out without widening scope.

- [x] T019 Run the targeted unit Sail/Pest command from `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/plan.md` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/quickstart.md` against `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Unit/Localization/LocaleResolverTest.php`
- [x] T020 Run the targeted feature Sail/Pest commands from `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/plan.md` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/quickstart.md` against `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/AuthAndSystemSurfaceLocalizationTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/LocalePreferenceFlowTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/WorkspaceDefaultLocaleTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Filament/Localization/CoreGovernanceSurfaceLocalizationTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/LocalizedNotificationFormattingTest.php`, `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/TranslationFallbackGuardTest.php`, and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform/tests/Feature/Localization/MachineFormatInvarianceTest.php`
- [x] T021 Run dirty-only Pint through Sail for touched platform files using the command recorded in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/quickstart.md`
- [x] T022 Record the final guardrail close-out, lane results, workflow outcome (`keep` unless implementation proves otherwise), and any bounded `document-in-feature` note for temporarily untranslated surfaces in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/plan.md` and `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/252-platform-localization-v1/checklists/requirements.md`

## Dependencies & Execution Order

### Phase Dependencies

- **Phase 1 (Setup)**: starts immediately.
- **Phase 2 (Foundational)**: depends on Phase 1 and blocks all user stories.
- **Phase 3 (US1)**, **Phase 4 (US2)**, and **Phase 5 (US3)**: each depends on Phase 2 and is independently testable after shared locale resolution and persistence exist.
- **Phase 6 (Polish)**: depends on all desired user stories being complete.

### User Story Dependencies

- **US1 (P1)**: first shippable increment once Phase 2 is complete.
- **US2 (P1)**: independently testable after Phase 2 and should follow US1 because translated shell and precedence behavior must already be stable.
- **US3 (P1)**: independently testable after Phase 2 and should merge after US1 because notifications, alert and operations feedback, and viewer shells depend on the same locale foundation.

### Within Each User Story

- Write the listed Pest coverage first and make it fail for the intended gap before implementation.
- Complete the shared resolver or persistence seam before wiring multiple UI entry points that depend on it.
- Re-run the narrowest relevant proof command after each story checkpoint before moving to the next story.

---

## Parallel Opportunities

### Phase 1

- T002 and T003 can run in parallel after T001 confirms the bounded slice.

### Phase 2

- T004, T005, and T006 can run in parallel.
- T007 should follow once resolver and persistence keys exist.

### User Story 1

- T008 can run in parallel with any final Phase 2 cleanup.
- T009 and T010 can proceed in parallel once the persistence shape is stable.
- T011 should follow after the locale-control surface exists.

### User Story 2

- T012 can run in parallel with final US1 validation once Phase 2 is complete.
- T013 and T014 can run in parallel after the first-wave inventory is fixed.
- T015 should follow to confirm semantics remain unchanged.

### User Story 3

- T016 can run in parallel with late US2 verification.
- T017 and T018 can run in parallel once the locale foundation is stable.

---

## Implementation Strategy

### Suggested MVP Scope

- MVP = **Phase 2 + User Story 1 + User Story 2 + User Story 3**. This is the smallest slice that establishes deterministic locale truth, translates the declared first-wave governance and feedback surfaces, and preserves invariant machine-readable artifacts.

### Incremental Delivery

1. Complete Phase 1 and Phase 2.
2. Deliver US1 and validate deterministic locale choice plus inheritance.
3. Deliver US2 and validate translated shell plus first-wave governance surfaces.
4. Deliver US3 and validate localized feedback, alert and operations copy, customer-safe viewer chrome, and invariant machine-readable artifacts.
5. Finish with Phase 6 validation, formatting, and feature-local close-out recording.
