 The `@typescript-eslint/no-deprecated` rule flags `React.FormEvent`. Since React's own type definition marks it deprecated, and there's no clean replacement that works across all React versions, the correct approach is to add an inline disable comment on the specific line: `// eslint-disable-next-line @typescript-eslint/no-deprecated`.

+
+## Phase 3c: E2E SSL Debugging (2026-04-19)
+
+### `staging.bantayog.web.app` is not a Firebase Hosting domain
+
+Firebase Hosting sites get URLs in the format `<site-id>.web.app`. The project `bantayog-alert-staging` has one site: `bantayog-alert-staging.web.app`. The domain `staging.bantayog.web.app` resolves to the same Firebase CDN IP but the SSL certificate is for `CN=firebaseapp.com` — it does not include this hostname as a SAN, causing `ERR_CERT_COMMON_NAME_INVALID`.
+
+**Rule:** Never assume a Firebase Hosting URL format. Always verify with `firebase hosting:sites:list` and `firebase hosting:channel:list`. Custom domains must be explicitly configured in Firebase Hosting.
+
+### E2E test BASE_URL must match webServer config
+
+When `playwright.config.ts` defines `webServer` entries for local dev servers (e.g., admin on port 5175), the corresponding spec files must default to the same localhost URL, not a staging URL. Otherwise tests fail with SSL errors when run locally even though the dev server is running.
+
+**Rule:** Spec file `BASE_URL` defaults should match the `webServer` ports in `playwright.config.ts`. Override with `process.env.BASE_URL` only for staging/CI runs.
+
+### Rate limit must be charged only on first execution, not idempotent replays
+
+When a callable uses both rate limiting and idempotency, the rate limit check must happen INSIDE the idempotency callback — after the cache miss path is confirmed. Otherwise, a legitimate client retry with the same idempotency key burns rate limit budget and can get `RATE_LIMITED` instead of the cached success response.
+
+**Rule:** Always place rate limit checks inside the `withIdempotency` callback, never before it.
+
+### Schema narrowing must propagate through the type chain
+
+When a Zod schema is narrowed (e.g., `advanceDispatchRequestSchema.to` from full `DispatchStatus` to a subset), all consumers of the inferred type must be updated. The typecheck won't flag the schema itself — it flags the call sites that pass wider types. Check all downstream consumers before narrowing a shared schema.
+
+**Rule:** After narrowing a shared validator schema, run `pnpm typecheck` immediately and fix all downstream call sites.
+
+### Firestore rules test doc structure must match actual schema
+
+If Firestore rules reference `resource.data.assignedTo.uid`, the test seed data must use `{ assignedTo: { uid: 'resp-1' } }`, not a flat `{ responderUid: 'resp-1' }`. Tests with wrong structure pass `assertFails` for the wrong reason (missing field → permission denied) and give false confidence.
+
+**Rule:** Before writing rules tests, read the actual Firestore rules to confirm which fields are checked. Cross-reference with the production document schema.
+
+### Placeholder e2e tests must use `test.skip()`, not empty bodies
+
+In Playwright (and Vitest), `test('name', async () => { /* comment */ })` passes green. This inflates coverage metrics. Use `test.skip()` or `test.fixme()` to make the intent explicit in CI reports.
+
+**Rule:** Every placeholder test must be `test.skip()` or `test.fixme()`. Never leave an empty test body.

+**Group B (3 hours)** - acceptDispatch callable
+
+- Task 4-6: Create callable, add tests, integrate with dispatcher
+
+**Group C (2 hours)** - Widen cancelDispatch
+
+- Task 7-8: Allow cancel from accepted/acknowledged/en_route/on_scene
+
+**Group D (2 hours)** - closeReport callable
+
+- Task 9-10: Create callable for admin incident closure
+
+**Group E (4 hours)** - Mirror trigger
+
+- Task 11-12: dispatch-mirror-to-report trigger with state mapping
+
+**Group F (3 hours)** - Firestore rules
+
+- Task 13-14: Rules for responder direct-write, admin operations
+

+
+- Task 27-31: Playwright specs for citizen, admin, responder, full-loop, race-loss
+
+**Group K (2 hours)** - Acceptance script
+
+- Task 32: End-to-end acceptance test
+
+**Group L (2 hours)** - Monitoring/docs
+
+- Task 33: Metrics and runbooks
+
+**Total Estimate:** 20-40 hours
+
+---
+
+## 📋 Implementation Commands
+
+### 1. Verify Staging (Manual)
+
+Follow checklist in `scripts/phase-3c/PRECONDITION_VERIFICATION.md`
+
+### 2. Run 3b Acceptance Test (After Staging Verification)
+
+```bash
+# Against local emulator
+firebase emulators:exec --only firestore \
+  "pnpm exec tsx scripts/phase-3b/acceptance.ts"
+
+# Against staging (requires service account)
+firebase emulators:start --only firestore
+pnpm exec tsx scripts/phase-3b/acceptance.ts --env=staging
+```
+
+### 3. Start Phase 3c Implementation
+
+```bash
+# You're already on the correct branch
+git branch  # Should show feature/phase-3c-responder-loop-e2e
+
+# Reference plan
+cat docs/superpowers/plans/2026-04-18-phase-3c-responder-loop-e2e.md
+
+# Start with Group B: acceptDispatch callable
+```
+
+---
+
+## 🔑 Key Implementation Notes
+
+### State Machine Changes Impact
+
+The following now work with the new state machine:
+
+1. **Responder Progression UI**
+   - "Heading there" button: `acknowledged → en_route`
+   - "Arrived on scene" button: `en_route → on_scene`
+   - "Complete incident" button: `on_scene → resolved`
+
+2. **Mirror Trigger**
+   - Uses `dispatchToReportState()` helper
+   - Maps: `en_route → 'en_route'`, `on_scene → 'on_scene'`
+   - Returns `null` for `cancelled` (cancelDispatch owns report write)
+
+3. **Firestore Rules**
+   - `validResponderTransition()` function includes all 21 transitions
+   - Responder can direct-write status updates
+   - Admin can cancel from any mid-lifecycle state
+
+### FCM Integration Points
+
+When implementing Group H (FCM pipeline):
+
+- VAPID keys must be provisioned first (see runbook)
+- Service worker registration: `apps/responder-app/src/sw/firebase-messaging-sw.ts`
+- FCM token registration: `useRegisterFcmToken` hook
+- Push notification sending: `functions/src/services/fcm-send.ts`
+
+---
+
+## 📊 Commit History

+# Phase 3c Readiness Fix Session Summary
+
+**Date:** 2026-04-19  
+**Session:** Systematic Debugging & State Machine Refactor  
+**Branch:** `feature/phase-3c-responder-loop-e2e`  
+**Duration:** ~2 hours  
+**Status:** ✅ CRITICAL BLOCKERS RESOLVED
+
+---
+
+## 🎯 Objective
+
+Fix critical architectural blockers preventing Phase 3c implementation, as identified in readiness assessment.
+
+---
+
+## ✅ Completed Work
+
+### Phase A: State Machine Refactor (CRITICAL - COMPLETE)
+
+**Problem:** Dispatch state machine used collapsed `in_progress` state instead of granular `en_route`/`on_scene` states required for Phase 3c responder progression.
+
+**Solution:** Systematic refactor following debugging workflow:
+
+1. **Extended dispatchStatusSchema** ✓
+   - Added `en_route` and `on_scene` to enum
+   - Removed deprecated `in_progress` state
+   - Updated timestamp fields (`enRouteAt`, `onSceneAt`)
+
+2. **Rewrote DISPATCH_TRANSITIONS** ✓
+   - Expanded from 5 to 21 transitions
+   - Added responder progression: `acknowledged → en_route → on_scene → resolved`
+   - Added admin cancel/supersede from mid-lifecycle states
+   - Added timeout transitions
+   - Created self-contained `dispatch-states.ts` (no longer coupled to report-states)
+
+3. **Added dispatchToReportState helper** ✓
+   - Pure translation function for mirror trigger
+   - Maps 9 dispatch states to ReportStatus|null
+   - Returns `null` for `cancelled` (handled by cancelDispatch callable)
+
+4. **Fixed state machine exports** ✓
+   - Now owned by validators package (not shared-types)
+   - dispatch-states.ts imports from dispatches.ts
+   - Correct source-of-truth pattern established
+
+5. **Regenerated Firestore rules** ✓

+
+## 🔄 Remaining Work (Manual Verification Required)
+
+### Staging Infrastructure Verification
+
+Before implementing Phase 3c features, manually verify:
+
+1. **Test accounts exist** (Firebase Console → Authentication)
+   - [ ] `citizen-test-01` (citizen)
+   - [ ] `daet-admin-test-01` (municipal_admin, daet, active)
+   - [ ] `bfp-responder-test-01` (responder, daet, bfp-daet, active)
+   - [ ] `responders/bfp-responder-test-01` document (isActive: true, fcmTokens: [])
+
+2. **Feature flag enabled** (Firestore Console → Data)
+   - [ ] `system_config/features/dispatch_mirror_enabled: true`
+
+3. **VAPID secrets provisioned** (Secret Manager)
+   ```bash
+   gcloud secrets versions list fcm-vapid-private-key \
+     --project=bantayog-alert-staging
+   ```
+   Expected: At least one version listed
+
+**Verification guide:** See `scripts/phase-3c/PRECONDITION_VERIFICATION.md`

+
+## 🔍 Key Insights
+
+### 1. Codegen Source-of-Truth Bug
+
+The `build-rules.ts` script was reading from `report-states.ts` instead of `dispatch-states.ts` for months. This explains why dispatch rules only had 5 transitions while the code evolved. The fix ensures TypeScript and Firestore rules stay synchronized.
+
+### 2. Architectural Ownership
+
+Validators package now owns the dispatch state machine (not shared-types). This restores the "validators own domain logic" pattern and prevents future drift.
+
+### 3. Forward Compatibility
+
+The `dispatchToReportState` helper returning `null` for `cancelled` is by design — the cancelDispatch callable owns the report write, not the mirror trigger. This prevents race conditions between cancellation and mirroring.

+
+### What was built
+
+**Responder PWA lifecycle:**
+
+- `useDispatch` hook + `DispatchDetailPage` — responder sees assigned dispatches via `onSnapshot`
+- `useAcceptDispatch` hook + Accept button — responder accepts via `acceptDispatch` callable
+- `useAdvanceDispatch` hook + progression buttons — acknowledge → en_route → on_scene → resolve
+- `CancelledScreen` + race-loss re-fetch — responder sees cancelled state when dispatch cancelled mid-flight
+- `dispatchTransition` helper — DRY consolidation of 4 status-step assertions in acceptance test
+
+**Acceptance gate (`scripts/phase-3c/acceptance.ts`):**
+
+- Complete lifecycle: dispatch → accept → acknowledge → en_route → on_scene → resolve → close
+- Idempotency guard: second `acceptDispatch` call with same idempotency key returns `accepted` (no error)
+- Cancel from accepted: `cancelDispatch` widens to accepted state (Phase 3c)
+- Terminal-state guard: `cancelDispatch` on resolved throws `FAILED_PRECONDITION`
+- Mirror sync: `dispatchMirrorToReport` fires async, updates `reports.status` on dispatch transitions
+
+**Playwright e2e specs (unblocked — SSL issue resolved):**
+
+- `citizen.spec.ts` — 6 passing tests (form, geolocation denial, lookup, invalid ref/secret)
+- `admin.spec.ts` — 7 tests for auth + triage + dispatch (BASE_URL fixed to localhost:5175)
+- `responder.spec.ts` — 10 tests for auth + dispatch list + progression
+- `full-loop.spec.ts` + `race-loss.spec.ts` — stub tests for full loop and race conditions
+

+# FCM VAPID Key Rotation Runbook
+
+**Purpose:** Rotate Firebase Cloud Messaging (FCM) VAPID keys for web push notifications.
+
+**VAPID Key Pair:**
+
+- **Public Key:** Exposed as `VITE_FCM_VAPID_PUBLIC_KEY` environment variable
+- **Private Key:** Stored in Google Secret Manager as `fcm-vapid-private-key`
+- **Purpose:** Enables web push notifications for responder PWA
+
+---
+
+## When to Rotate
+
+Rotate VAPID keys when:
+
+- Keys are compromised or exposed
+- Annual security rotation (recommended)
+- Migrating to new FCM infrastructure
+
+---
+
+## Prerequisites
+
+1. **Firebase Project:** `bantayog-alert-staging` or `bantayog-alert-prod`
+2. **Google Cloud SDK:** `gcloud` CLI installed and authenticated
+3. **Project Access:** Owner or Secret Manager Admin role
+
+---
+
+## Step 1: Generate New VAPID Key Pair
+
+```bash
+# Using web-push library (Node.js)
+npx web-push generate-vapid-keys
+
+# Output example:
+# VAPID public key: BCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+# VAPID private key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+```
+
+**Save both keys securely.** The private key is sensitive and must never be committed to git.
+
+---
+
+## Step 2: Store Private Key in Secret Manager
+
+```bash
+# For staging
+gcloud secrets create fcm-vapid-private-key \
+  --project=bantayog-alert-staging \
+  --data-file=<(echo "YOUR_PRIVATE_KEY_HERE") \
+  --labels=env=staging,purpose=fcm-vapid
+
+# For production
+gcloud secrets create fcm-vapid-private-key \
+  --project=bantayog-alert-prod \
+  --data-file=<(echo "YOUR_PRIVATE_KEY_HERE") \
+  --labels=env=prod,purpose=fcm-vapid
+```
+
+**If secret already exists (rotation):**
+
+```bash
+# Add new version
+gcloud secrets versions add fcm-vapid-private-key \
+  --project=bantayog-alert-staging \
+  --data-file=<(echo "YOUR_NEW_PRIVATE_KEY_HERE")
+
+# Set as latest (automatic)
+# Optionally disable old version after verification
+gcloud secrets versions disable VERSION_ID \
+  --project=bantayog-alert-staging \
+  --secret=fcm-vapid-private-key
+```
+
+---
+
+## Step 3: Grant Access to Cloud Functions Service Account
+
+```bash
+# Get the default Compute Service Account for the project
+PROJECT_ID="bantayog-alert-staging"
+SA_EMAIL="${PROJECT_ID}@appspot.gserviceaccount.com"
+
+# Grant Secret Manager Viewer access
+gcloud secrets add-iam-policy-binding fcm-vapid-private-key \
+  --project=$PROJECT_ID \
+  --role="roles/secretmanager.secretAccessor" \
+  --member="serviceAccount:$SA_EMAIL"
+```
+
+---
+
+## Step 4: Update Environment Variables
+
+### For Development (.env.local)
+
+```bash
+# .env.local (never commit)
+VITE_FCM_VAPID_PUBLIC_KEY=BCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+```
+
+### For Staging/Production (Firebase Hosting config)
+
+Update `firebase.json` or hosting config:
+
+```json
+{
+  "hosting": {
+    "env": {
+      "VITE_FCM_VAPID_PUBLIC_KEY": {
+        "value": "BCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
+        "apply": "staging"
+      }
+    }
+  }
+}
+```
+
+Or use `firebase functions:config:set`:
+
+```bash
+firebase functions:config:set fcm.vapid_public_key="BCxxxxxxxxxxxxxxxxx" \
+  --project=bantayog-alert-staging
+```
+
+---
+
+## Step 5: Deploy Updated Configuration
+
+```bash
+# Deploy hosting config with new env vars
+firebase deploy --only hosting --project=bantayog-alert-staging
+
+# If using Cloud Functions environment
+firebase deploy --only functions --project=bantayog-alert-staging
+```
+
+---
+
+## Step 6: Verify Push Notifications Work
+
+1. **Open responder PWA:** `https://staging.bantayog-alert.web.app`
+2. **Accept notification prompt** (or enable in settings)
+3. **Subscribe to FCM topics** (if applicable)
+4. **Trigger test dispatch** from admin desktop
+5. **Verify push notification received** on responder device
+
+**Debug FCM issues:**
+
+- Browser DevTools → Application → Service Workers
+- Check Firebase Console → Cloud Messaging → Reports
+- Verify `navigator.serviceWorker.ready` resolves
+
+---
+
+## Rollback Procedure
+
+If issues occur after rotation:
+
+1. **Revert to previous secret version:**
+
+   ```bash
+   gcloud secrets versions enable OLD_VERSION_ID \
+     --project=bantayog-alert-staging \
+     --secret=fcm-vapid-private-key
+
+   gcloud secrets versions disable NEW_VERSION_ID \
+     --project=bantayog-alert-staging \
+     --secret=fcm-vapid-private-key
+   ```
+
+2. **Redeploy Cloud Functions** (if using config):
+
+   ```bash
+   firebase deploy --only functions --project=bantayog-alert-staging
+   ```
+
+3. **Verify notifications resume**
+
+---
+
+## Security Notes
+
+- **Private keys are single-use.** Never reuse a private key across projects.
+- **Public keys are safe to expose.** They're sent to browsers for subscription validation.
+- **Store private keys securely.** Use Secret Manager, never commit to git.
+- **Rotate regularly.** Annual rotation is recommended for security hygiene.
+- **Monitor access.** Use Cloud Audit Logs to track who accesses secrets.

+## ✓ Automated Checks (Complete)
+
+1. ✅ **State machine fixed** — Dispatch states now have `en_route` and `on_scene`
+2. ✅ **Transitions expanded** — 21 transitions (up from 5)
+3. ✅ **Firestore rules regenerated** — Rules include new transitions
+4. ✅ **Tests passing** — All 127 tests pass with new state machine
+5. ✅ **VAPID runbook created** — `docs/runbooks/fcm-vapid-rotation.md`
+6. ✅ **Feature branch created** — `feature/phase-3c-responder-loop-e2e`
+

+
+## ⚠️ Manual Verification Required
+
+### 1. Test Accounts Exist in Staging
+
+**Accounts to verify:**
+
+| Account ID              | Type            | Purpose                      | Verification Command                      |
+| ----------------------- | --------------- | ---------------------------- | ----------------------------------------- |
+| `citizen-test-01`       | Citizen         | Reporter in acceptance tests | Firebase Console → Authentication → Users |
+| `daet-admin-test-01`    | Municipal Admin | Admin triage acceptance      | Firebase Console → Authentication → Users |
+| `bfp-responder-test-01` | Responder       | Responder dispatch tests     | Firebase Console → Authentication → Users |
+
+**Verification Steps:**
+
+1. Open Firebase Console: https://console.firebase.google.com/project/bantayog-alert-staging/authentication/users
+2. Search for each account by UID
+3. Verify claims for each:
+   - `citizen-test-01`: No special claims needed (citizen role)
+   - `daet-admin-test-01`: `role: municipal_admin`, `municipalityId: daet`, `active: true`
+   - `bfp-responder-test-01`: `role: responder`, `municipalityId: daet`, `agencyId: bfp-daet`, `active: true`
+
+**If accounts missing, run bootstrap:**
+
+```bash
+# For emulator (local testing)
+pnpm exec tsx scripts/phase-3b/bootstrap-test-responder.ts --emulator
+
+# For staging (requires admin SDK credentials)
+GOOGLE_APPLICATION_CREDENTIALS=path/to/key.json pnpm exec tsx scripts/phase-3b/bootstrap-test-responder.ts
+```
+
+**Verify responder document:**
+
+1. Open Firestore Console: https://console.firebase.google.com/project/bantayog-alert-staging/firestore/data
+2. Navigate to: `responders/bfp-responder-test-01`
+3. Verify:
+   - `isActive: true`
+   - `fcmTokens: []` (empty until Phase 3c registers token)
+   - `municipalityId: daet`
+   - `agencyId: bfp-daet`
+
+---
+
+### 2. Feature Flag Enabled
+
+**Document:** `system_config/features/dispatch_mirror_enabled`
+
+**Verification Steps:**
+
+1. Open Firestore Console: https://console.firebase.google.com/project/bantayog-alert-staging/firestore/data
+2. Navigate to: `system_config/features`
+3. Verify field `dispatch_mirror_enabled` is `true`
+
+**Expected document structure:**
+
+```javascript
+{
+  dispatch_mirror_enabled: true,
+  updatedAt: Timestamp(...),
+  // ... other feature flags
+}
+```
+
+**If missing, create document:**
+
+```javascript
+// Via Firestore Console
+collection: system_config
+document ID: features
+fields:
+  dispatch_mirror_enabled: true
+  updatedAt: FieldValue.serverTimestamp()
+```
+
+Or via Firebase shell:
+
+```bash
+firebase firestore:main --project bantayog-alert-staging <<EOF
+collection system_config
+  doc features
+    set {
+      dispatch_mirror_enabled: true,
+      updatedAt: Timestamp.now()
+    }
+EOF
+```
+
+---
+
+### 3. VAPID Secrets Provisioned
+
+**Secrets to verify:**
+
+| Secret Name                 | Purpose                | Location                 |
+| --------------------------- | ---------------------- | ------------------------ |
+| `fcm-vapid-private-key`     | FCM push notifications | Secret Manager (staging) |
+| `VITE_FCM_VAPID_PUBLIC_KEY` | Web push subscription  | Environment variable     |
+
+**Verification Steps:**
+
+1. Check Secret Manager:
+
+   ```bash
+   gcloud secrets versions list fcm-vapid-private-key --project=bantayog-alert-staging
+   ```
+
+   Expected: At least one version listed (e.g., `1`)
+
+2. Check environment variable:
+   - Open Firebase Console → Hosting → Config
+   - Verify `VITE_FCM_VAPID_PUBLIC_KEY` is set
+
+**If missing, follow VAPID rotation runbook:**
+
+```bash
+# 1. Generate VAPID keys
+npx web-push generate-vapid-keys
+
+# 2. Store private key in Secret Manager
+gcloud secrets create fcm-vapid-private-key \
+  --project=bantayog-alert-staging \
+  --data-file=<(echo "YOUR_PRIVATE_KEY_HERE")
+
+# 3. Grant access to functions service account
+PROJECT_ID="bantayog-alert-staging"
+SA_EMAIL="${PROJECT_ID}@appspot.gserviceaccount.com"
+
+gcloud secrets add-iam-policy-binding fcm-vapid-private-key \
+  --project=$PROJECT_ID \
+  --role="roles/secretmanager.secretAccessor" \
+  --member="serviceAccount:$SA_EMAIL"
+
+# 4. Update environment variables (see docs/runbooks/fcm-vapid-rotation.md)
+```
+
+---
+
+## ✓ Verification Checklist
+
+Run this checklist before starting Phase 3c implementation:
+
+- [ ] `citizen-test-01` auth account exists
+- [ ] `daet-admin-test-01` exists with valid claims (role, muni, active)
+- [ ] `bfp-responder-test-01` exists with valid claims
+- [ ] `responders/bfp-responder-test-01` document exists (isActive: true, fcmTokens: [])
+- [ ] `system_config/features/dispatch_mirror_enabled` is `true`
+- [ ] `fcm-vapid-private-key` secret exists in Secret Manager (staging)
+- [ ] `VITE_FCM_VAPID_PUBLIC_KEY` environment variable is set
+
+**All boxes checked?** → Proceed with Phase 3c implementation  
+**Any box unchecked?** → Complete setup step before proceeding
+
+---
+
+## 🚨 Blockers
+
+If any of these are missing, Phase 3c implementation **CANNOT PROCEED**:
+
+1. ❌ Missing test accounts → Run bootstrap scripts
+2. ❌ Feature flag missing → Create `system_config/features` document
+3. ❌ VAPID secrets missing → Follow VAPID rotation runbook (critical for FCM)
+
+---
+
+## 📋 Post-Verification Actions
+
+Once all preconditions are verified:
+
+1. **Run acceptance test** (verifies 3b still works):
+
+   ```bash
+   firebase emulators:exec --only firestore "pnpm exec tsx scripts/phase-3b/acceptance.ts"
+   ```
+
+2. **Create tracking issue** for Phase 3c implementation tasks
+
+3. **Begin Phase 3c implementation** following plan:
+   - `docs/superpowers/plans/2026-04-18-phase-3c-responder-loop-e2e.md`
+
+---
+
+**Verification Script:** `scripts/phase-3c/verify-preconditions.ts` (automates staging checks when run with `--env=staging`)
+
+---
+
+**Last Updated:** 2026-04-19  
+**Status:** Manual verification required before 3c implementation
