 ## Overview
 
-This checklist tracks the integration of the TimeSafari Daily Notification Plugin into the main TimeSafari PWA project. The plugin provides enterprise-grade daily notification functionality with dual scheduling, callback support, TTL-at-fire logic, and comprehensive observability across Web (PWA), Mobile (Capacitor), and Desktop (Electron) platforms.

 ### Phase 3: TimeSafari Architecture Integration
 
 #### 3.1 Privacy-Preserving Claims Architecture
-- [ ] Integrate plugin with TimeSafari's endorser.ch architecture
-- [ ] Implement DIDs (Decentralized Identifiers) support in plugin
-- [ ] Add cryptographic verification patterns to plugin
-- [ ] Configure plugin for user-controlled visibility
-- [ ] Test plugin with TimeSafari's privacy-preserving patterns
-- [ ] Verify DID/VC flows integrate with **Veramo** stack already present in the app (`@veramo/*`, `did-jwt`, `did-resolver`, `web-did-resolver`). Include example notification payloads signed or referenced via DID where applicable
-- [ ] Provide **sample DID-signed payloads** and verification steps in docs; include **revocation / expiration** examples
-- [ ] Add **data retention** and **field-level redaction** policy for logs/analytics events emitted by the plugin

 #### 3.2 Database Integration with TimeSafari Storage
-- [ ] Integrate plugin storage with TimeSafari's SQLite/Absurd SQL approach
-- [ ] Configure plugin to use TimeSafari's database patterns
-- [ ] Implement IndexedDB compatibility for legacy browsers
-- [ ] Test plugin storage with TimeSafari's database architecture
-- [ ] Validate data persistence across TimeSafari's storage layers
-- [ ] Define a **storage adapter contract** (interface) with versioning and migration notes; forbid the plugin from owning its own DB lifecycle
