  • Implemented structured metrics export: exportMetrics() (JSON export) and getMetricsSummary() (lightweight summary)
  • Enhanced error context: logError() method with structured error data including DailyNotificationError codes and stack traces
  • Added opt-in diagnostic mode: enableDiagnosticMode(), disableDiagnosticMode(), isDiagnosticMode(), getDiagnosticInfo() methods
  • Enhanced error serialization: Added toJSON() method to DailyNotificationError class
  • Verification: All observability enhancements non-invasive, CI passes, no breaking changes
• 2025-12-22 — P3.3 COMPLETE: Developer experience improvements
  • Enhanced error messages: Added ERROR_GUIDANCE constant with actionable guidance and platform hints for all error codes
  • Added NOT_SUPPORTED error code for platform-specific operations
  • Updated web.ts to use DailyNotificationError instead of plain Error

  • Scenario A: DST boundary + duplicate delivery + cold start (must-have)
    • Tests recovery idempotency under DST transitions
    • Verifies only one logical delivery recorded after dedupe
    • Validates next notification time is DST-consistent
  • Scenario B: Rollover + duplicate delivery + cold start (must-have)
    • Tests rollover idempotency under re-entry
    • Verifies duplicate delivery doesn't double-apply state transitions
    • Validates cold start reconciliation produces correct state
  • Scenario C: Schema version metadata + cold start recovery (nice-to-have)
    • Confirms P2.1 schema version metadata is present and logged
    • Verifies version check doesn't interfere with recovery
  • Implementation: Added to ios/Tests/DailyNotificationRecoveryTests.swift

    • Similar to iOS TestDBFactory.swift but uses Room in-memory databases
  • P2.3.3: Implemented 3 combined test scenarios
    • Scenario A: test_combined_dst_boundary_duplicate_delivery_cold_start() - DST + duplicate + cold start
    • Scenario B: test_combined_rollover_duplicate_delivery_cold_start() - Rollover + duplicate + cold start
    • Scenario C: test_combined_schema_version_cold_start_recovery() - Schema version + cold start
  • Parity: Android now has automated combined edge case tests matching iOS P2.2 intent
  • Implementation: Added to android/src/test/java/com/timesafari/dailynotification/DailyNotificationRecoveryTests.kt
  • Test Labels: All tests labeled with @resilience @combined-scenarios comments
  • Verification: Tests runnable via ./gradlew test on Android environment
• 2025-12-22 — P1.5b COMPLETE: Moved iOS/App test harness out of published tree
  • Action: Moved ios/App/ to test-apps/ios-app-legacy/ (legacy test harness)
  • Rationale: Test harness should not be in published package tree
  • Active Test App: test-apps/ios-test-app/ remains the active test app
  • Verification: Confirmed ios/App no longer appears in npm pack --dry-run output
  • Impact: Cleaner package structure, test harness clearly separated from library code
• P1.5 COMPLETE: Documentation consolidation phase finished

• Tightened package.json "files" field to exclude ios/App/ and Xcode user state files
• Enhanced verify.sh forbidden files check to include ios/App/ pattern and additional editor/macOS junk files
• Moved GitHub Actions workflow to docs/_reference/ (reference only, not used)
• Established local CI as single source of truth (./ci/run.sh)

  • Migrated definitions.ts to re-export core contracts/enums instead of duplicating
  • Migrated web.ts to use canonical types from core
• P1.4: Enhanced verify.sh with core module purity enforcement

  • Export validation: Node-based check for package.json.exports['./core']
  • Split checks: source validation (pre-build) + artifact validation (post-build)

Added

• ci/run.sh - Local CI entrypoint (wraps ./scripts/verify.sh)
• ci/README.md - Local CI documentation
