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 for NOT NULL constraint violation.
Problem:
- Worker service calls getSessionById(sessionDbId) to fetch session data
- Worker then uses dbSession.claude_session_id to create ActiveSession
- But getSessionById was NOT selecting claude_session_id from database
- Result: claudeSessionId = undefined in worker
- Caused: "NOT NULL constraint failed: sdk_sessions.claude_session_id" errors
- Impact: Observations and summaries couldn't be stored
Root cause:
- SessionStore.getSessionById() SQL query missing claude_session_id column
- Line 710-713: "SELECT id, sdk_session_id, project, user_prompt"
- Should be: "SELECT id, claude_session_id, sdk_session_id, project, user_prompt"
Fix:
- Added claude_session_id to SELECT query in getSessionById
- Updated return type to include claude_session_id: string
- Now worker correctly receives claude_session_id from database
- Session ID from hook flows properly through entire system
Files changed:
- src/services/sqlite/SessionStore.ts (getSessionById method)
Testing:
- Build succeeded
- Ready for PM2 restart and live testing

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

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:

- Clarified that summaries are mid-session checkpoints, not session endings
- Improved request field instructions to better form descriptive titles
- Changed wording from "discovered" to "learned" for consistency
Technical changes:
- Updated src/sdk/prompts.ts summary prompt

- Changed the title of the summary prompt to "THIS REQUEST'S SUMMARY" for better context.
- Revised instructions to focus on summarizing what was built/fixed/deployed/configured, rather than the observation process.
- Clarified when not to summarize, emphasizing conversational requests and trivial inquiries.
- Updated examples to better illustrate good summary practices.
Improvements to SessionStart context hook file display:
1. **Remove redundant files**: Files in "Modified" list are now excluded from "Read" list
- Prevents duplication when a file was both read and modified
- Reduces token usage by eliminating redundant information
2. **Use relative paths**: Convert absolute paths to project-relative paths
- Example: /Users/alexnewman/Scripts/claude-mem/src/hooks/context.ts → src/hooks/context.ts
- Significantly reduces token consumption in context injection
- Makes file references more readable and portable
Implementation:
- Added toRelativePath() helper function to convert paths
- Added filesModifiedSet.forEach(file => filesReadSet.delete(file)) to remove duplicates
- Applied to both files_read and files_modified when building Sets
Impact: Reduces token usage in Tier 1 summaries (most recent session) where file lists are displayed.

Added "WHEN NOT TO SUMMARIZE" section to buildSummaryPrompt that instructs the SDK to skip creating summaries for:
- Work already covered in previous prompts (prevents duplicates)
- Conversational banter with no deliverables
- Trivial requests (questions, status checks)
- Meta-discussions about memory system without shipped changes
Implementation:
- src/sdk/prompts.ts: Added WHEN NOT TO SUMMARIZE section with <skip_summary> output format
- src/sdk/parser.ts: Added skip_summary detection before parsing full summary XML
- src/sdk/parser.ts: Fixed observation type validation to include all 6 types (bugfix, feature, refactor, change, discovery, decision)
This should eliminate the duplicate summaries like the three "restore 6 types" summaries we saw for session d9137878.

Restored full type system: bugfix, feature, refactor, change, discovery, decision.
This enables more precise search queries like "show all bugfixes in auth" vs generic "show all changes".
Also updated README to reflect current behavior (10 summaries with three-tier verbosity).
Changes:
- prompts.ts: Expanded type field from 3 to 6 types with clear definitions
- CLAUDE.md: Fixed context hook description (3 → 10 summaries)

Updated SDK prompts to distinguish between deliverables (what was built/shipped) vs meta-operations (what the memory system is doing). This prevents self-referential pollution like "Process tool executions" instead of actual coding tasks like "Fix authentication bug".
Changes:
- buildInitPrompt: Added deliverable-focused framing with contrastive examples
- buildSummaryPrompt: Injected user's original prompt + explicit examples
- Added verb guidance (implemented/fixed/deployed vs analyzed/tracked/stored)
- Added "NOW DOES" present-tense capability framing
Works across all project types: dev, DevOps, docs, infrastructure, research, config.
