Bugfix:
- Fixed duplicate observations and summaries appearing in viewer
- Root cause: handleSessionInit spawned SDK agent but didn't save promise to session.generatorPromise
- Second agent would spawn when handleObservations ran, causing duplicates
- Fix: Assign generatorPromise in handleSessionInit (matches handleSummarize pattern)
Technical changes:
- Modified src/services/worker-service.ts:265
- Now tracks promise to prevent duplicate agent spawning
- Guard condition in handleObservations (line 301) now works correctly

Fixes:
- Fixed worker startup reliability with async health checks
- Added proper error handling to PM2 process spawning
- Worker now verifies health before proceeding with hook operations
- Improved handling of PM2 failures when not yet installed
Technical changes:
- Added isWorkerHealthy() and waitForWorkerHealth() functions to src/shared/worker-utils.ts
- Changed ensureWorkerRunning() from synchronous to async with proper await
- All hooks now await ensureWorkerRunning for reliable worker communication
- Rebuilt all plugin executables with version 5.0.2

Root cause: ensureWorkerRunning was synchronous and didn't verify worker was actually responsive before proceeding, causing race conditions and startup failures.

Critical bugfix release.
Problem:
- NOT NULL constraint violations prevented all observations/summaries from being stored
- Worker service could not store any data in database
- System was completely non-functional for new sessions
Root Cause:
- SessionStore.getSessionById() missing claude_session_id in SELECT query
- Worker received undefined for claude_session_id
- Caused database INSERT failures
Fix:
- Added claude_session_id to getSessionById SQL query
- Updated return type to include claude_session_id field
- Session ID now flows correctly: hook → database → worker → SDK
Impact:
- All observation and summary storage now works correctly
- System maintains session consistency throughout lifecycle
- Critical for proper functioning of memory compression
Version Changes:
- package.json: 4.2.7 → 4.2.8
- marketplace.json: 4.2.6 → 4.2.8
- CLAUDE.md: Updated version and added v4.2.8 changelog
Files Changed:
- package.json (version bump)
- .claude-plugin/marketplace.json (version bump)
- CLAUDE.md (version and changelog)
- src/services/sqlite/SessionStore.ts (bugfix)
- plugin/scripts/* (rebuilt with fix)

Critical Bugfix:
- Fixed overly defensive observation validation blocking observations from being saved
- Parser now NEVER skips observations - always saves them
- Invalid or missing type defaults to "change" (generic catch-all type)
- Removed validation requiring title, subtitle, and narrative fields
- Prevents critical data loss - partial observations better than no observations
Impact:
- Before: Missing title, subtitle, OR narrative caused entire observation to be discarded
- After: ALL observations preserved regardless of field completeness
- Even partial observations contain valuable data: concepts, files_read, files_modified, facts
- LLMs make mistakes - system must be resilient and save everything
- Consistent with v4.2.5 summary fix
Technical changes:
- Updated src/sdk/parser.ts:52-67 to never skip observations
- Uses "change" as fallback type for invalid/missing types (no schema change)
- Updated ParsedObservation interface to allow null for title, subtitle, narrative
- Updated SessionStore.storeObservation signature to accept nullable fields
- Updated built worker-service.cjs
- Bumped version to 4.2.6 in all metadata files

Critical Bugfix:
- Fixed overly defensive summary validation blocking summaries from being saved
- Removed validation that returned null when any required fields were missing
- Summaries now always saved when <summary> tags present, even if incomplete
- Prevents critical data loss - partial summaries better than no summaries
Impact:
- Before: Missing single field caused entire summary to be discarded
- After: All summaries preserved, maintaining session context when incomplete
- Ensures continuity of memory compression system
Technical changes:
- Updated src/sdk/parser.ts:137-147 to remove blocking validation
- Parser returns ParsedSummary with whatever fields are available
- Updated built worker-service.cjs
- Bumped version to 4.2.5 in all metadata files
