# Tasks: Backup/Restore UI Graph-Safety (Phase 1)

**Input**: Design documents from `/specs/048-backup-restore-ui-graph-safety/`
**Prerequisites**: plan.md (required), spec.md (required), research.md, data-model.md, contracts/, quickstart.md

**Tests**: REQUIRED (Pest). This feature explicitly adds guard tests (FR-004).

**Organization**: Tasks are grouped by user story to enable independent implementation and testing.

## Format: `- [ ] T### [P?] [US#?] Description with file path`

- **[P]**: Can run in parallel (different files, no dependencies)
- **[US#]**: Which user story this task belongs to (US1, US2)
- Include exact file paths in descriptions

---

## Phase 1: Setup (Shared Infrastructure)

**Purpose**: Confirm scope, lock stable UI markers as concrete strings, and ensure the contracts/quickstart reflect the intended test approach.

- [ ] T001 Confirm tenant-scoped admin URLs for target pages in specs/048-backup-restore-ui-graph-safety/contracts/admin-pages.openapi.yaml
- [ ] T002 Lock stable marker strings and record them in specs/048-backup-restore-ui-graph-safety/quickstart.md:
	- Backup Sets index marker: `Created by`
	- Restore wizard create marker: `Create restore run` (and wizard step: `Select Backup Set`)

---

## Phase 2: Foundational (Blocking Prerequisites)

**Purpose**: Shared test helpers and a clear boundary that fails-hard when Graph is touched.

**⚠️ CRITICAL**: No user story work should be considered “done” unless the fail-hard Graph binding is used in the story’s feature tests.

- [ ] T003 [P] Create a fail-hard Graph client test double in tests/Support/FailHardGraphClient.php (implements App\\Services\\Graph\\GraphClientInterface and throws on any method)
- [ ] T004 Add a reusable binding helper for tests (either a helper function in tests/Pest.php or a trait in tests/Support/) that binds GraphClientInterface to FailHardGraphClient

**Checkpoint**: Foundation ready — both page-render tests can now be implemented.

---

## Phase 3: User Story 1 — Backup Sets index renders Graph-free (Priority: P1) 🎯 MVP

**Goal**: As a tenant admin, I can open the Backup Sets index page even when Graph is disabled.

**Independent Test**: A Pest feature test does an HTTP GET to the tenant-scoped Filament Backup Sets index route and asserts assertOk() + assertSee('Created by') — with Graph bound to fail-hard.

### Tests

- [ ] T005 [P] [US1] Add Pest feature test in tests/Feature/Filament/BackupSetGraphSafetyTest.php:
	- bind GraphClientInterface to FailHardGraphClient (fail-hard on ANY invocation)
	- HTTP GET App\\Filament\\Resources\\BackupSetResource::getUrl('index', tenant: $tenant)
	- assertOk() + assertSee('Created by')
- [ ] T006 [US1] In tests/Feature/Filament/BackupSetGraphSafetyTest.php, add tenant isolation assertions (second tenant data must not render) while still using fail-hard Graph binding

### Implementation

- [ ] T007 [US1] Audit Backup Sets render path for any Graph usage and refactor to DB-only if needed in app/Filament/Resources/BackupSetResource.php and app/Filament/Resources/BackupSetResource/Pages/ListBackupSets.php

**Checkpoint**: Backup Sets index renders (assertOk() + assertSee('Created by')) with fail-hard Graph binding.

---

## Phase 4: User Story 2 — Restore wizard renders Graph-free + DB-only group mapping (Priority: P1)

**Goal**: As a tenant admin, I can open the Restore wizard page and interact with group mapping without any Graph calls in render/mount/options/typeahead.

**Independent Test**: Pest feature tests that (a) render the Restore wizard create page without Graph, and (b) render the group mapping section (using query params to preselect a backup set with group assignments) and verify fallback labels use `…<last8>`.

### Tests

- [ ] T008 [P] [US2] Add Pest feature test in tests/Feature/Filament/RestoreWizardGraphSafetyTest.php:
	- bind GraphClientInterface to FailHardGraphClient (fail-hard on ANY invocation)
	- HTTP GET App\\Filament\\Resources\\RestoreRunResource::getUrl('create', tenant: $tenant)
	- assertOk() + assertSee('Create restore run') + assertSee('Select Backup Set')
- [ ] T009 [P] [US2] Extend tests/Feature/Filament/RestoreWizardGraphSafetyTest.php (or a second file):
	- seed a BackupSet + BackupItem with group assignment targets (groupId present)
	- HTTP GET create URL with `?backup_set_id=` (and optional `backup_item_ids`/`scope_mode`) to force group mapping render
	- keep fail-hard Graph binding (no Graph/typeahead/label resolution allowed)
- [ ] T010 [US2] In the group mapping render test, assert all DB-only UX requirements:
	- assertSee('…<last8>') masked fallback appears for source labels
	- assertSee('Paste the target Entra ID group Object ID') helper text appears
	- assertSee('Use SKIP to omit the assignment.') helper text appears

### Implementation

- [ ] T011 [US2] Remove Graph-dependent typeahead/search from group mapping controls in app/Filament/Resources/RestoreRunResource.php (no Graph/typeahead; remove getSearchResultsUsing paths)
- [ ] T012 [US2] Remove Graph-dependent option label resolution in app/Filament/Resources/RestoreRunResource.php (no Graph label resolution; remove getOptionLabelUsing paths)
- [ ] T013 [US2] Implement DB-only group mapping UX in app/Filament/Resources/RestoreRunResource.php:
	- manual target group objectId input (GUID/UUID)
	- GUID validation (if not SKIP)
	- helper text: “Paste the target Entra ID group Object ID (GUID). Names are not resolved in this phase.” + “Use SKIP to omit the assignment.”
	- no Graph/typeahead
- [ ] T014 [US2] Make unresolved group detection DB-only in app/Filament/Resources/RestoreRunResource.php (remove GroupResolver usage from unresolvedGroups() and any other render-time helpers)
- [ ] T015 [US2] Implement masked fallback label formatting `…<last8>` in app/Filament/Resources/RestoreRunResource.php (update formatGroupLabel() and ensure all source labels route through it)
- [ ] T016 [US2] Remove now-unused methods/imports after refactor (e.g., targetGroupOptions(), resolveTargetGroupLabel(), GroupResolver import) in app/Filament/Resources/RestoreRunResource.php

**Checkpoint**: Restore wizard renders (assertOk() + assertSee('Create restore run') + assertSee('Select Backup Set')) and group mapping renders DB-only; tests pass with fail-hard Graph binding.

---

## Phase 5: Polish & Cross-Cutting Concerns

**Purpose**: Keep docs and tooling aligned with the guardrail.

- [ ] T017 [P] Update specs/048-backup-restore-ui-graph-safety/quickstart.md with the final test file names and the exact `artisan test --filter=...` / file commands
- [ ] T018 [P] Update specs/048-backup-restore-ui-graph-safety/contracts/admin-pages.openapi.yaml if any page paths/markers changed during implementation
- [ ] T019 Run formatting (./vendor/bin/pint --dirty) and targeted tests (./vendor/bin/sail artisan test --filter=graph\-safety or the exact files)

---

## Dependencies & Execution Order

### Phase Dependencies

- **Setup (Phase 1)**: No dependencies
- **Foundational (Phase 2)**: Depends on Setup completion — BLOCKS both user stories
- **US1 + US2 (Phases 3–4)**: Depend on Foundational completion; can proceed in parallel
- **Polish (Phase 5)**: Depends on desired user stories being complete

### User Story Dependencies

- **US1 (P1)**: Depends on T003–T004; otherwise independent
- **US2 (P1)**: Depends on T003–T004; otherwise independent

### Parallel Opportunities

- T003 and T004 can be developed in parallel if split across files.
- US1 test work (T005–T006) and US2 test work (T008–T010) can be developed in parallel.

---

## Parallel Example

```bash
# Parallelizable work after Phase 2:
# - US1: tests/Feature/Filament/BackupSetGraphSafetyTest.php
# - US2: tests/Feature/Filament/RestoreWizardGraphSafetyTest.php
# - Shared helper: tests/Support/FailHardGraphClient.php
```

## Implementation Strategy

### MVP Scope (Recommended)

1. Phase 1–2 (setup + fail-hard Graph test binding)
2. Phase 3 (US1: Backup Sets index renders Graph-free)
3. Validate tests + stop

### Then

4. Phase 4 (US2: Restore wizard + group mapping Graph-free)
5. Phase 5 polish
