feat: add bulk client notifications and email enhancements with review fixes (Stories 3.4 & 3.5)

Story 3-4: Bulk client notification scheduling — BulkNotificationController,
BulkActionBar component, checkbox selection on declarations index.

Story 3-5: Email notification enhancement — observer-driven email on
en_attente_client, cache invalidation on ferme, workspace branding on
all email templates, 11 feature tests.

Code review fixes:
- Move bulk-notify route above resource wildcard to prevent shadowing
- Add static $suppressEmail flag to prevent observer double-sending
  when DeclarationMessageController already sends the email
- Fix canBulkNotify logic (was granting workers access)
- Add WorkspaceUserRole check to BulkNotifyRequest::authorize()
- Replace firstOrCreate with explicit invitation lookup that syncs
  client email and handles used/expired invitations correctly
- Watch declarations.data instead of current_page to clear selection
  on filter/sort changes

+# Story 3.4: Bulk Client Notification Scheduling
+
+Status: review
+
+## Story
+
+As a firm worker or manager,
+I want to send document request notifications to multiple clients at once,
+so that I can efficiently request missing documents without emailing each client individually.
+
+## Acceptance Criteria (BDD)
+
+1. **Given** a user (Owner/Manager/Worker with assigned declarations) is viewing the declarations list
+   **When** they select multiple declarations with status `en_attente_client` using row checkboxes
+   **Then** a BulkActionBar appears showing "[N] selected" and a "Notify Clients" button
+
+2. **Given** the user clicks "Notify Clients" on the BulkActionBar
+   **When** the confirmation dialog appears
+   **Then** it shows the count of clients to be notified and a "Send Notifications" confirmation button
+
+3. **Given** the user clicks "Send" in the confirmation dialog
+   **When** the POST request is dispatched to the bulk notification endpoint
+   **Then** each client receives a personalized email with their token-based portal link for document upload
+   **And** emails are queued individually via Redis (non-blocking -- controller returns immediately)
+   **And** a success toast confirms: "[N] notifications envoyees"
+
+4. **Given** 50 client notifications are scheduled
+   **When** the queue processes them
+   **Then** all 50 emails are sent within 10 seconds (NFR3)
+   **And** failed individual sends retry automatically (up to 3 retries per NFR26)
+   **And** the bulk operation is logged via Spatie Activity Log with the count and actor
+
+5. **Given** a Worker user selects declarations
+   **Then** they can only bulk-notify clients for their own assigned declarations (enforced server-side via `scopeForUser`)
+
+6. **Given** the existing email template `DeclarationFileRequestMail` exists
+   **Then** it is reused for the notification content (no new mailable needed)
+

+## Retrospective Intelligence
+
+### From Epic 2 Retro (2026-03-24)
+- **Deferred item D-1:** Nudge/Reassign dropdown items were unconditionally disabled in Story 2.3 -- resolved in Story 3.2. No carryover for 3.4.
+- **Deferred item D-3:** Cache not invalidated on role change (5-min TTL mitigates). If bulk notifications touch notification counts, invalidate cache per `Cache::forget("user:{$userId}:workspace:{$workspaceId}:unread_notifications")`.
+- **Pre-existing test failures:** 15 failures were resolved in commit `716e9fc`. Ensure no new regressions.
+
+### From Epic 1 Retro (2026-03-20)
+- **withPivot gotcha:** Always use `->withPivot('role', 'permissions')` when accessing `WorkspaceUser` pivot. This hit 3/6 stories in Epic 1.
+- **Previous Story Intelligence** sections in story specs enable knowledge transfer -- validated pattern.
+
+### From Epic 0 Retro (2026-03-13)
+- Layered migration strategy works well. No new migrations needed for this story.
+
+## Dev Notes
+
+### Architecture Patterns (MUST FOLLOW)
+
+| Pattern | Implementation | Source |
+|---------|---------------|--------|
+| Workspace scoping | `HasWorkspaceScope` trait, `abort(404)` for boundary violations | architecture.md D7 |
+| Queued notifications | `ShouldQueue` trait, `$tries = 3`, `$backoff = 60` | architecture.md D5 |
+| Bulk operations | `DB::transaction()` for validation, Redis queue for sends | architecture.md D9 |
+| Activity logging | `activity()->performedOn()->causedBy()->log()` | NudgeController pattern |
+| Cache invalidation | `Cache::forget("user:{id}:workspace:{id}:unread_notifications")` | NotificationController pattern |
+
+### Existing Code to Reuse (DO NOT REINVENT)
+
+| What | Where | How to Reuse |
+|------|-------|-------------|
+| `DeclarationFileRequestMail` | `app/Mail/DeclarationFileRequestMail.php` | Use directly -- accepts `Declaration`, `DeclarationInvitation`, `string body` |
+| `DeclarationInvitation` model | `app/Models/DeclarationInvitation.php` | Creates token-based portal links for clients |
+| `HasWorkspaceScope` trait | `app/Concerns/HasWorkspaceScope.php` | `use HasWorkspaceScope` + `$this->authorizeWorkspaceAccess()` |
+| `NotificationType::BulkNotification` | `app/Enums/NotificationType.php` | Already defined as `'bulk_notification'` with label `'Notification groupee'` |
+| `Declaration::scopeForUser()` | `app/Models/Declaration.php` | Scopes to assigned declarations for Workers |
+| Frontend `bulk_notification` icon | `resources/js/Pages/notifications/Index.vue` | Already mapped to `Mail` icon from lucide |
+| `NudgeController` | `app/Http/Controllers/NudgeController.php` | Reference pattern for workspace auth + activity logging |
+
+### Controller Pattern (Follow NudgeController)
+
+```php
+// BulkNotificationController.php structure:
+class BulkNotificationController extends Controller
+{
+    use HasWorkspaceScope;
+
+    public function store(Request $request): RedirectResponse
+    {
+        $validated = $request->validate([
+            'declaration_ids' => ['required', 'array', 'min:1'],
+            'declaration_ids.*' => ['integer'],
+        ]);
+
+        $workspace = $this->currentWorkspace();
+        $user = $request->user();
+        $workspaceUser = $workspace->users()->where('users.id', $user->id)->firstOrFail();
+
+        // Load declarations with workspace + user scoping
+        $declarations = Declaration::where('workspace_id', $workspace->id)
+            ->forUser($user, $workspaceUser)
+            ->where('status', 'en_attente_client')
+            ->whereIn('id', $validated['declaration_ids'])
+            ->get();
+
+        // Queue emails (non-blocking)
+        foreach ($declarations as $declaration) {
+            // Find or create invitation with token for client portal
+            $invitation = $declaration->invitations()->firstOrCreate([...]);
+            Mail::to($declaration->client->email)
+                ->queue(new DeclarationFileRequestMail($declaration, $invitation, $body));
+        }
+
+        // Activity log
+        activity()
+            ->performedOn($workspace)
+            ->causedBy($user)
+            ->withProperties(['count' => $declarations->count(), 'declaration_ids' => $declarations->pluck('id')])
+            ->log('bulk_client_notification');
+
+        // Invalidate notification caches for affected users if database notifications created
+
+        return back()->with('flash', [
+            'type' => 'success',
+            'message' => $declarations->count() . ' notifications envoyees',
+        ]);
+    }
+}
+```
+
+### Declaration Status Values
+
+Per project-context.md: `created`, `en_cours`, `en_attente_client`, `mise_en_demeure`, `termine`, `ferme`
+
+Only declarations with status `en_attente_client` are eligible for bulk client notifications.
+
+### Frontend Implementation Notes
+
+- **Checkbox column:** Add as first column in the declarations table. Use reactive `ref<number[]>([])` for selected IDs.
+- **BulkActionBar:** Fixed position bottom bar using Tailwind `fixed bottom-0`. Use `Transition` for show/hide animation.
+- **Confirmation:** Use shadcn-vue `AlertDialog` (same pattern as delete confirmations in the codebase).
+- **Submission:** Use `router.post(props.bulkNotifyUrl, { declaration_ids: selectedIds.value })` -- NOT `useForm()` since there's no traditional form.
+- **Toast:** Already handled by flash message system via `back()->with('flash', ...)`.
+- **Props to add to Index.vue:** `bulkNotifyUrl: string`, `canBulkNotify: boolean`.
+
+### Testing Standards
+
+- Use Pest `test()` closures with lowercase descriptions
+- `RefreshDatabase` auto-applied via Pest.php
+- Test file: `tests/Feature/Notifications/BulkNotificationTest.php`
+- Assert `Mail::fake()` + `Mail::assertQueued(DeclarationFileRequestMail::class, $count)`
+- Assert `Activity` model for log entries
+- Test workspace isolation: create declaration in different workspace, assert 404
+
+### File Structure
+
+```
+app/Http/Controllers/BulkNotificationController.php    (NEW)
+resources/js/components/declarations/BulkActionBar.vue  (NEW)
+resources/js/Pages/declarations/Index.vue               (MODIFY - add checkboxes, bulk bar)
+app/Http/Controllers/DeclarationController.php          (MODIFY - add bulkNotifyUrl prop)
+routes/web.php                                          (MODIFY - add bulk-notify route)
+tests/Feature/Notifications/BulkNotificationTest.php    (NEW)
+```
+
+### Project Structure Notes
+
+- Controller follows single-action pattern in `app/Http/Controllers/` (consistent with NudgeController)
+- Vue component in `resources/js/components/declarations/` (co-located with NudgePopover)
+- Test in `tests/Feature/Notifications/` (consistent with notification test organization)
+- No new migrations, models, or enums required -- all infrastructure exists from Stories 3.1-3.3
+
+### Performance (NFR3)
+
+- 50 emails within 10 seconds is achievable because emails are individually queued to Redis
+- Controller returns immediately (non-blocking) -- queue workers handle actual sends
+- Each `DeclarationFileRequestMail` is already `Queueable` with `SerializesModels`
+- Redis queue processes jobs concurrently via multiple workers

+# Story 3.5: Email Notification Enhancement for Key Events
+
+Status: review
+
+## Story
+
+As a platform user,
+I want to receive email notifications for important events (nudges, document uploads, status changes),
+So that I stay informed about critical actions even when I'm not actively using the platform.
+
+## Acceptance Criteria
+
+1. **AC1 — Nudge email enhancement**: Given a worker receives a nudge from a manager, when the `NudgeNotification` processes via queue, then the worker receives an email with: sender name, declaration details (client, type, deadline), and a direct link button ("Voir la declaration"). The email uses the existing `NudgeNotificationMail` Markdown mailable with professional French copy.
+
+2. **AC2 — Document upload: database-only (no email)**: Given a client uploads a document via the portal, when the upload is confirmed, then the assigned worker receives a `DocumentUploadedNotification` in-app (database channel only — no email for uploads to avoid noise).
+
+3. **AC3 — Status change: en_attente_client triggers client email**: Given a declaration's status changes, when the `DeclarationObserver` fires and the new status is `en_attente_client`, then the client receives the existing document request email via their token link (reuses `DeclarationFileRequestMail`).
+
+4. **AC4 — Status change: ferme triggers cache invalidation**: Given a declaration's status changes to `ferme`, when the `DeclarationObserver` fires, then dashboard cache is invalidated (from Story 2.1 `Cache::forget` pattern).
+
+5. **AC5 — Email retry on failure**: Given email delivery fails, when the queue retries, then the system retries up to 3 times within 5 minutes (NFR26), and permanently failed emails are logged to the `failed_jobs` table for monitoring. All queued emails use `ShouldQueue` and `Queueable` traits.
+
+6. **AC6 — Business context filtering**: Email notifications respect business context: no email is sent for minor status transitions (e.g., `created` -> `en_cours`). Only `en_attente_client` (triggers client email) and `ferme` (triggers cache invalidation) have side effects.
+
+7. **AC7 — Workspace branding**: All email templates include the workspace firm name and logo in the header.
+
+## Tasks / Subtasks
+
+- [x] Task 1: Enhance `DeclarationObserver` with notification dispatching (AC: #3, #4, #6)
+  - [x] 1.1 Add `updated()` hook to `DeclarationObserver` (separate from `updating()` — runs after save)
+  - [x] 1.2 When status changes to `en_attente_client`: look up the declaration's client, find or create `DeclarationInvitation` with token, queue `DeclarationFileRequestMail` to the client email
+  - [x] 1.3 When status changes to `ferme`: invalidate dashboard cache via `Cache::forget("dashboard:{$workspace_id}:*")` pattern
+  - [x] 1.4 Skip email for all other transitions (`created->en_cours`, `en_cours->en_attente_client` already handled, `termine->ferme`, etc.)
+  - [x] 1.5 Dispatch `StatusChangedNotification` (database channel) to assigned worker for status changes they didn't initiate (optional enhancement — only if straightforward)
+
+- [x] Task 2: Verify nudge email flow is complete (AC: #1)
+  - [x] 2.1 Confirm `NudgeNotification` already sends via `mail` channel with `NudgeNotificationMail` — this is ALREADY IMPLEMENTED in Story 3.2
+  - [x] 2.2 Verify `nudge-notification.blade.php` has professional French copy with sender name, client, type, due_date, "Voir la declaration" button — ALREADY EXISTS
+  - [x] 2.3 If any gaps found, fix them; otherwise mark as already complete
+
+- [x] Task 3: Verify DocumentUploadedNotification stays database-only (AC: #2)
+  - [x] 3.1 Confirm `DocumentUploadedNotification` `via()` returns `['database']` only — ALREADY IMPLEMENTED in Story 3.1
+  - [x] 3.2 No changes needed unless a gap is found
+
+- [x] Task 4: Add workspace branding to email templates (AC: #7)
+  - [x] 4.1 Ensure `firmName` (workspace name) is passed to all email templates that don't already have it
+  - [x] 4.2 Update `declaration-overdue.blade.php` to include firm name in header (currently missing)
+  - [x] 4.3 Verify `nudge-notification.blade.php` already includes `firmName` — it does
+  - [x] 4.4 For logo: pass `workspace.logo_url` if the field exists, otherwise skip logo (workspace model may not have logo yet — do NOT add a migration for this)
+
+- [x] Task 5: Ensure retry configuration on all email-sending notifications (AC: #5)
+  - [x] 5.1 Verify `NudgeNotification` has `$tries = 3`, `$backoff = 60` — ALREADY SET
+  - [x] 5.2 Verify `DeclarationOverdueNotification` has `$tries = 3`, `$backoff = 60` — ALREADY SET
+  - [x] 5.3 Any new notification classes must follow the same pattern
+
+- [x] Task 6: Write feature tests (AC: all)
+  - [x] 6.1 Test: status change to `en_attente_client` triggers `DeclarationFileRequestMail` queue
+  - [x] 6.2 Test: status change to `ferme` invalidates dashboard cache
+  - [x] 6.3 Test: status change to `en_cours` does NOT trigger any email
+  - [x] 6.4 Test: `DocumentUploadedNotification` has no mail channel
+  - [x] 6.5 Test: nudge email contains required fields (sender, client, type, due_date, link)
+  - [x] 6.6 Test: workspace scoping on all notification dispatches
+  - [x] 6.7 Test: failed email retries (verify `$tries` and `$backoff` properties)
+
+## Retrospective Intelligence
+
+- **Load retro as context is non-negotiable** (Epic 2 retro team agreement). This story incorporates all retro lessons.
+- **`withPivot('role', 'permissions')` gotcha** — any query touching `workspace_user` pivot must chain this, or pivot data is null. Relevant if checking user roles during notification dispatch.
+- **`due_date` not `deadline`** — architecture doc drift identified in Epic 2 retro. The column is `due_date` everywhere in code.
+- **Wayfinder routes only** — no hardcoded URLs in Vue. Use `route()` helper in PHP for email links. This is already the pattern in `NudgeNotificationMail` (uses `route('declarations.show', $this->declaration)`).
+- **`withoutVite()` in tests** — global Pest.php workaround from Story 2.4. Tests should work without Vite running.
+- **Cache invalidation pattern** — `Cache::forget("dashboard:{$workspaceId}:{$userId}")` established in Story 2.1. For bulk invalidation across all workspace users, iterate workspace members or use a tag-based approach.
+- **Pre-existing test failures were fixed** in commit `716e9fc`. Test suite should be green.
+- **DB::transaction for multi-step operations** — established pattern. Use for invitation creation + email queueing if doing both.
+
+## Dev Notes
+
+### What Already Works (DO NOT Rebuild)
+
+**Nudge email flow is COMPLETE** — `NudgeNotification` dispatches via `['database', 'mail']` channels. `NudgeNotificationMail` uses `emails.nudge-notification` Markdown template with sender name, firm name, client, type, due date, and "Voir la declaration" button. Retry configured at 3 tries / 60s backoff. **No changes needed unless testing reveals a gap.**
+
+**DocumentUploadedNotification is database-only by design** — `via()` returns `['database']`. The AC explicitly says "no email for uploads to avoid noise." **No changes needed.**
+
+**DeclarationOverdueNotification has mail channel** — uses `MailMessage` with `emails.declaration-overdue` Markdown template. Retry configured. **No changes needed unless branding update required.**
+
+**Existing Mailable classes** — `DeclarationFileRequestMail`, `DeclarationConfirmationMail`, etc. already exist in `app/Mail/`. Reuse `DeclarationFileRequestMail` for the `en_attente_client` status change flow.
+
+### What Needs to Be Built
+
+**Primary new work: Enhance `DeclarationObserver`** to dispatch notifications/emails on status transitions:
+
+1. Add `updated()` method (runs AFTER save, unlike `updating()` which runs before):
+   - Check if `status` changed via `$declaration->isDirty('status')` — BUT note: in `updated()`, use `$declaration->wasChanged('status')` instead of `isDirty()` since the model has already been saved
+   - If new status is `en_attente_client`: queue client email via existing `DeclarationFileRequestMail`
+   - If new status is `ferme`: bust dashboard cache for all workspace users
+
+2. **Client email on `en_attente_client`**:
+   - Load the declaration's client: `$declaration->client`
+   - Find or create a `DeclarationInvitation` with a unique token for the client portal link
+   - Queue `DeclarationFileRequestMail` to the client's email address
+   - The `DeclarationInvitation` model and token-based portal already exist (from the brownfield codebase)
+
+3. **Cache invalidation on `ferme`**:
+   - The `updating()` hook already sets `archived_at = now()` for `ferme`
+   - In `updated()`, also bust dashboard cache: get workspace users, `Cache::forget()` for each
+
+### Architecture Compliance
+
+- **Observer pattern**: `DeclarationObserver` is already registered in `AppServiceProvider`. Add `updated()` alongside existing `updating()`.
+- **Queue pattern**: All email sends must be queued (`ShouldQueue` + `Queueable`). Never send synchronously.
+- **Workspace scoping**: Notifications include `workspace_id` in payload. Email dispatch respects workspace boundaries.
+- **Activity logging**: Status changes are already logged by `LogsActivity` trait on Declaration model. No additional logging needed.
+- **Error handling**: Failed emails go to `failed_jobs` table automatically via Laravel queue worker (`--tries=3`).
+
+### File Structure
+
+**Files to modify:**
+- `app/Observers/DeclarationObserver.php` — Add `updated()` method with email dispatch and cache invalidation
+- `resources/views/emails/declaration-overdue.blade.php` — Add firm name to template header (workspace branding)
+
+**Files to verify (no changes expected):**
+- `app/Notifications/NudgeNotification.php` — Confirm mail channel and retry config
+- `app/Notifications/DocumentUploadedNotification.php` — Confirm database-only
+- `app/Notifications/DeclarationOverdueNotification.php` — Confirm retry config
+- `app/Mail/NudgeNotificationMail.php` — Confirm template data
+- `resources/views/emails/nudge-notification.blade.php` — Confirm French copy
+
+**Files to create:**
+- `tests/Feature/Notifications/EmailNotificationTest.php` — New test file for this story's ACs
+
+### Existing Code Patterns to Follow
+
+**Observer `updated()` pattern:**
+```php
+public function updated(Declaration $declaration): void
+{
+    if (! $declaration->wasChanged('status')) {
+        return;
+    }
+    // Use wasChanged() not isDirty() in updated() hook
+    $newStatus = $declaration->status instanceof DeclarationStatus
+        ? $declaration->status->value
+        : (string) $declaration->status;
+    // Dispatch based on new status...
+}
+```
+
+**Mail queueing pattern (from BulkNotificationController):**
+```php
+Mail::to($client->email)->queue(
+    new DeclarationFileRequestMail($declaration, $invitation, $body)
+);
+```
+
+**Cache invalidation pattern (from DashboardController):**
+```php
+// Bust cache for all workspace users
+$workspaceUsers = $workspace->users()->pluck('users.id');
+foreach ($workspaceUsers as $userId) {
+    Cache::forget("dashboard:{$workspace->id}:{$userId}");
+}
+```
+
+**Test pattern (Pest, from BulkNotificationTest):**
+```php
+test('status change to en_attente_client queues client email', function () {
+    Mail::fake();
+    // ... setup declaration, change status ...
+    Mail::assertQueued(DeclarationFileRequestMail::class);
+});
+```
+
+### Project Structure Notes
+
+- All code follows established directory conventions. No new directories needed.
+- Observer is already wired in `AppServiceProvider` boot method.
+- Email templates live in `resources/views/emails/` using Markdown mailable syntax (`<x-mail::message>`).
+- Tests go in `tests/Feature/Notifications/` alongside existing notification tests.
+
+### Critical Gotchas
+
+1. **`isDirty()` vs `wasChanged()`**: In `updating()` (before save), use `isDirty()`. In `updated()` (after save), use `wasChanged()`. The existing `updating()` correctly uses `isDirty()`. The new `updated()` must use `wasChanged()`.
+
+2. **DeclarationInvitation token**: Check how `BulkNotificationController` creates invitations. It likely creates a `DeclarationInvitation` record with a unique token. Reuse that exact pattern — do NOT invent a new token mechanism.
+
+3. **Client email address**: Clients are stored in the `clients` table with an `email` field. Access via `$declaration->client->email`. Handle null email gracefully (skip sending, don't crash).
+
+4. **Mail::to() vs Notification::send()**: For client emails, use `Mail::to()->queue()` directly (clients are not `Notifiable` users). For internal user notifications, use `$user->notify(new SomeNotification())`.
+
+5. **Cache invalidation scope**: When busting dashboard cache on `ferme`, only bust for users in the same workspace. Get workspace users via `$declaration->workspace->users()`.
+
+6. **Observer infinite loop risk**: The `updated()` hook must NOT modify the declaration model (which would trigger another `updating`/`updated` cycle). Only dispatch external side effects (emails, cache busting).

+## Dev Agent Record
+
+### Agent Model Used
+Claude Opus 4.6 (1M context)
+
+### Debug Log References
+- Full test suite: 274 passed, 0 failures (including 11 new tests)
+
+### Completion Notes List
+- **Task 1**: Added `updated()` hook to `DeclarationObserver` with two private methods: `sendClientFileRequestEmail()` (queues `DeclarationFileRequestMail` on `en_attente_client` using DB transaction + invitation creation pattern from `BulkNotificationController`) and `invalidateDashboardCache()` (busts `dashboard:{workspace_id}:{user_id}` cache for all workspace users on `ferme`). Uses `wasChanged()` (not `isDirty()`) as required in post-save hook. Skipped optional Task 1.5 (StatusChangedNotification) as it would add complexity beyond story scope.
+- **Task 2**: Verified nudge email flow is fully implemented — `NudgeNotification` sends via `['database', 'mail']`, `NudgeNotificationMail` renders `nudge-notification.blade.php` with all required fields. No gaps found.
+- **Task 3**: Verified `DocumentUploadedNotification::via()` returns `['database']` only. No changes needed.
+- **Task 4**: Added `firmName` (workspace name) to `DeclarationOverdueNotification` mail data and `declaration-overdue.blade.php` header. Added `firmName` to `DeclarationFileRequestMail` content and `declaration-file-request.blade.php` header. Nudge template already had it. Workspace has no `logo_url` field — skipped logo per story instructions.
+- **Task 5**: Verified retry config (`$tries = 3`, `$backoff = 60`) on `NudgeNotification` and `DeclarationOverdueNotification`. No new notification classes created.
+- **Task 6**: Created 11 feature tests covering all ACs: email dispatch on `en_attente_client`, cache invalidation on `ferme`, no email on `en_cours`, database-only channel check, nudge email content, workspace scoping, and retry properties.
+
+### Change Log
+- 2026-03-26: Implemented Story 3.5 — Email notification enhancement for key events. Added observer-driven email dispatch and cache invalidation, workspace branding on all email templates, 11 new feature tests. All 274 tests pass.
+
+### File List
+- `app/Observers/DeclarationObserver.php` — Modified: added `updated()` method with email dispatch and cache invalidation
+- `app/Notifications/DeclarationOverdueNotification.php` — Modified: added `firmName` to mail data
+- `app/Mail/DeclarationFileRequestMail.php` — Modified: added `firmName` to template content
+- `resources/views/emails/declaration-overdue.blade.php` — Modified: added firm name in header
+- `resources/views/emails/declaration-file-request.blade.php` — Modified: added firm name in header
+- `tests/Feature/Notifications/EmailNotificationTest.php` — Created: 11 feature tests for all ACs
