## Integration Phases

### Phase 1: Package Preparation & Publishing

#### 1.1 Package Configuration
- [ ] Update `package.json` with correct TimeSafari repository URL
- [ ] Align package name with TimeSafari naming conventions (`@timesafari/daily-notification-plugin`)
- [ ] Update version to match TimeSafari release cycle
- [ ] Add proper keywords and description for TimeSafari context
- [ ] Update author and license information
- [ ] Add TimeSafari-specific peer dependencies
- [ ] Configure package for Vite compatibility (ESM/CJS dual build)
- [ ] Add an `exports` map in `package.json` to ensure ESM-first resolution in Vite 5 and Node 18+
- [ ] Confirm dual builds: `module` (ESM) and `main` (CJS) remain valid for bundlers; keep `types` pointed at ESM d.ts
- [ ] Replace placeholder repo fields with TimeSafari org URLs (`repository.url`, `bugs.url`)
- [ ] Add `"sideEffects": false` if tree-shaking is safe
- [ ] **Release scripts (no CI/CD):** add `standard-version` (or `changesets`) and npm scripts:

  * `release:prepare` → runs tests, typecheck, bundle-size check, generates changelog, bumps version, creates a local tag
  * `release:publish` → pushes tag and publishes to npm (or your registry)
  * `release:notes` → opens/updates draft Release Notes with links to evidence artifacts
- [ ] Declare **engines** (Node ≥ 18) to match Vite 5 toolchain expectations
- [ ] Publish **types** checksum via **local script** (`npm run types:checksum`) to catch accidental API changes (commit checksum file)
- [ ] **Public API guard (local)**: `npm run api:check` (API Extractor or dts diff) **must pass** before any release; if the API changed, use `feat` or include **BREAKING CHANGE** in notes
- [ ] **Local quality-gates scripts present**: `npm run size:check`, `npm run api:check`, `npm run types:checksum` are implemented in `scripts/` and referenced from Release Notes

#### 1.2 Repository Integration
- [ ] Create integration branch in TimeSafari PWA repository
- [ ] Setup plugin as submodule or local package
- [ ] Configure git submodule or local installation path
- [ ] Test basic repository access and cloning
- [ ] Verify TimeSafari PWA repository structure matches documented architecture
- [ ] Confirm access to TimeSafari's privacy-preserving claims architecture

#### 1.3 Publishing Strategy
- [ ] **Option A**: Local package installation (recommended for development)
  - [ ] Configure `npm install file:./daily-notification-plugin`
  - [ ] Test local installation in TimeSafari PWA
  - [ ] Validate package resolution and imports
  - [ ] Test Vite build integration with local package
- [ ] **Option B**: Git-based installation
  - [ ] Configure git-based installation with correct TimeSafari repository URL
  - [ ] Test git-based installation
  - [ ] Validate branch/tag resolution
  - [ ] Test build integration with git-based package
- [ ] **Option C**: Private npm registry
  - [ ] Setup private npm registry access
  - [ ] Publish plugin to private registry
  - [ ] Configure TimeSafari PWA to use private registry
  - [ ] Test registry-based installation and build

#### 1.4 Workspace / Monorepo Linking
- [ ] Prefer **workspace linking** (npm/pnpm/yarn) during integration; ensure the plugin package name remains `@timesafari/daily-notification-plugin`
  *Rationale: aligns with TimeSafari's multi-platform build scripts and keeps local iteration fast.*

### Phase 2: Dependency Alignment

#### 2.1 Capacitor Version Compatibility (v6 target)
- [ ] Upgrade plugin deps to **@capacitor/core 6.x** and platform packages to **6.x**
- [ ] Re-test plugin registration/initialization against Capacitor 6 bridge

- [ ] iOS: validate BGTaskScheduler identifiers and notification permission flow on iOS 17+
- [ ] Maintain a **compat matrix** (plugin@version ↔ Capacitor major) in the README
- [ ] README **compatibility matrix** links to the example app "Quick Smoke Test" and the **Manual Smoke Test** doc (no CI)
- [ ] Re-test **permission prompts** & "provisional" iOS notification flows; document UX paths and fallbacks
- [ ] Validate **deferred/deadline** behaviors vs. **TTL-at-fire logic** across OS versions (Android 12–14, iOS 15–18)

### Phase 9 Complete

* [ ] **Observability implemented & verified**

  * [ ] Structured log schema (`event_id`, `category`, `action`, `result`, `duration_ms`, `opaque_ref`) merged and referenced by examples.
  * [ ] Metrics emitted: `notif_schedules_total`, `notif_fires_total`, `notif_deferrals_total`, `notif_failures_total`, `notif_user_optouts_total`, `notif_callback_errors_total`.
  * [ ] Histogram: `notif_fire_latency_ms` (schedule→fire)
    * "Buckets cover 0.5m, 1m, 2m, 5m, 10m, 20m, 60m to align with P50/P95 SLO visualization."
  * [ ] Gauge: `notif_backlog_depth` (pending schedules)
    * "Definition: count of scheduled notifications with `fire_at ≤ now` not yet delivered; sampled every minute."
  * [ ] Trace hooks available (init → schedule → fire → callback) and disabled by default; enablement documented.
  * [ ] Sample dashboard JSON **committed**. Attach `dashboards/notifications.observability.json` to the **Release Notes** (manual step) after a seeded local test run.
  * [ ] **Redaction guarantees**: unit tests prove titles/bodies/IDs are redacted or hashed in logs; no PII appears in captured samples. 
* [ ] **Accessibility & localization validated**

  * [ ] A11y labels present for all actions; screen-reader audit completed with pass notes (include tool + date).
  * [ ] i18n keys exist for all user-visible strings; **en** and **fil** translations included and loaded at runtime.
  * [ ] Fallback copy verified when translation missing; tests assert fallback path without runtime errors. 
* [ ] **Legal & store compliance documented**

  * [ ] Android background delivery limits, Doze/App Standby notes, and notification channel policy linked in README.
  * [ ] iOS BGTaskScheduler identifiers, capabilities, and notification policy linked in README.
  * [ ] **Data retention** table (fields, retention period, purpose, storage location) added; consent/opt-out behaviors documented.
  * [ ] App Store / Play Store checklist items mapped to implementation locations (file + section). 
* [ ] **Operational readiness**

  * [ ] Alerting rules created for **failure rate**, **deferral spike**, and **callback error rate** (include thresholds) and tested with synthetic events. Thresholds: `notif_failures_total` **>1%** of fires (15m rolling), `notif_deferrals_total` **>5%** of schedules (1h), `notif_callback_errors_total` **>0.5%** of fires (15m). Include **playbook links** in rule annotations; each rule links to the relevant section of `runbooks/notification_incident_drill.md` and is **referenced from the Release Notes**.
  * [ ] Runbook added: triage steps, log/metric queries, rollback/disable instructions for the notification feature flag. 
  * [ ] **Evidence artifacts archived** (commit & link in docs):

    * `dashboards/notifications.observability.json`
    * `alerts/notification_rules.yml`
    * `a11y/audit_report.md` (tool + date)
    * `i18n/coverage_report.md`
    * `security/redaction_tests.md` (unit test outputs)
  * [ ] **Runbook drills logged**: at least one on-call drill executed; outcome and time-to-mitigation recorded in `runbooks/notification_incident_drill.md` 
* [ ] **Performance & load**

  * [ ] Bundle-size budget verified by local script (`npm run size:check`) **before release**; block release if exceeded.
  * [ ] Battery/network impact smoke tests executed; results recorded with acceptable thresholds and mitigation notes.
