Changed hardcoded port 5432 to read from POSTGRES_PORT environment
variable to support pgbouncer connection pooling (port 6432).
Connection pooling reduces overhead for frequent queries and better
handles concurrent connections.
.env now configured with POSTGRES_PORT=6432 (pgbouncer).

- Check if session exists before inserting commit link
- Auto-create minimal session record if missing (status=active, no project)
- Prevents FK constraint violation when cache/DB drift occurs
- Return message indicates if session was auto-created for monitoring
- Handles edge cases: concurrent calls, missing committed_at, NULL project

CF-303 IP exposure validation. Changed to generic message.

Added validation to check if session_id exists in sessions table before
inserting memories. Falls back to NULL if session not found, preventing
foreign key constraint violations while preserving memory content.
Logs warning when invalid session_id provided for debugging.

Added task_move_project tool to move tasks between projects while
preserving all relationships and history:
Changes:
- db.ts: Added getClient() for transaction support
- crud.ts: Implemented taskMoveProject() with full transaction
- index.ts: Wired up tool handler and import
- tools/index.ts: Registered tool definition
Preserves:
- Task metadata (title, description, type, status, priority)
- Checklist items
- Linked commits
- Delegations
- Activity history
- Task links (relates_to, blocks, duplicates)
- Epic and version assignments
- Embeddings
Process:
1. Validates source task and target project exist
2. Generates new ID in target project
3. Transfers all related data in transaction
4. Marks old task as completed with reference
5. Creates duplicate link between tasks

deployment status, timing, git integration, and structured logging.
Also adds run-migration.mjs helper for running migrations against
PostgreSQL database.
Part of CF-290, completes CF-291.

Phase 7 complete: Advanced session analysis capabilities
New MCP Tools (3):
1. session_semantic_search - Vector similarity search across all sessions
2. session_productivity_analytics - Metrics (avg duration, tasks, commits, tokens)
3. session_pattern_detection - Detect patterns (tool usage, task types)
Features:
- Semantic search with embedding-based similarity
- Fallback to ILIKE text search if embeddings unavailable
- Analytics over configurable time periods (week/month/quarter)
- Pattern detection with frequency analysis
Use Cases:
- Find similar past work: "sessions about WhatsApp integration"
- Track productivity: avg commits/tasks per session
- Identify tool usage patterns: which tools used most often
- Analyze task type distribution
All 7 phases complete! System ready for testing.

Switch from external Gemini API (3072 dims, $0.15/1M tokens) to local
Ollama mxbai-embed-large (1024 dims, free) for cost savings and HNSW
index support.
Changes:
- Updated embeddings.ts: model 'mxbai-embed-large', API URL fixed
- Updated migration 015: vector(1024) with HNSW index
- Regenerated 268 tool_docs embeddings with new model
Benefits:
- Free embeddings (no API costs)
- HNSW index enabled (1024 < 2000 dim limit)
- Fast similarity search (O(log n) vs O(n))
- No external API dependency
Trade-offs:
- 5% quality loss (MTEB 64.68 vs ~70 Gemini)
- Uses local compute (1.2GB RAM, <1s per embedding)
Task: CF-251

- Added session existence check before INSERT
- Graceful degradation: sets session_id to null if invalid
- Prevents FK constraint violation
- Memory still stored without session link
- Updated db.ts to use infra.agiliton.internal with env var fallback
- Updated run.js to use infra.agiliton.internal for DB_HOST
- Rebuilt dist files with new configuration

Enhancements:
1. Session Context Table
- Migration 014: session_context table
- Tracks current working task per session
- Auto-updated on task status changes
2. Auto-Linking to Current Working Task
- When task status → in_progress: sets as current_task_id
- When task status → completed: clears current_task_id
- New tasks auto-link to current working task with 'relates_to'
- Shows auto-link message during task creation
3. Session ID Resolution
- Fixed path: ~/.cache/session-memory/current_session
- Falls back to environment variable CLAUDE_SESSION_ID
- Generates timestamp-based ID if unavailable
Example Flow:
```
1. task update CF-123 --status in_progress
→ Sets CF-123 as current working task
2. task add --title "Related work"
→ Created: CF-124
🔗 Auto-linked to: CF-123 (current working task)
3. task update CF-123 --status completed
→ Clears current working task
```
Files Changed:
- migrations/014_session_context.sql (new, 33 lines)
- src/tools/crud.ts (auto-linking logic, session context management)
Benefits:
- Zero manual linking for related work
- Session context preserved automatically
- Investigation workflows auto-organized
- Retroactive work tracking prevented
Note: Requires MCP server restart to take effect.
Remaining CF-166 Features (Phase 3):
- task investigate command
- Investigation workflow helper
- Task creation reminders

Implemented 8 new session management tools:
- session_start: Initialize session with metadata tracking
- session_update: Update session metrics during execution
- session_end: Close session with summary and embedding
- session_list: List sessions with filtering
- session_search: Semantic search across sessions
- session_context: Get complete session context (tasks, commits, builds, memories)
- build_record: Link builds to sessions and versions
- session_commit_link: Link commits to sessions
Enhanced existing tools:
- memory_add: Added session_id and task_id parameters
- Updated all memory queries to use 'memories' table (renamed from session_memories)
Implementation:
- Created src/tools/sessions.ts with all session operations
- Updated src/tools/memories.ts for new schema
- Added 8 session tool definitions to src/tools/index.ts
- Registered all session tools in src/index.ts switch statement
- TypeScript compilation successful
Related: CF-167 (Fix shared session-summary.md file conflict)
- db.ts: Hardcode 10.0.1.1 (infra VM) to prevent env var issues
- index.ts: Start MCP server before DB connection (fixes Claude Code timing)
- run.sh/run.js: Add wrapper scripts with embedded env vars
- start.sh: Update with correct WireGuard config
Fixes task-mcp failing to connect in Claude Code sessions after
WireGuard migration. The server must respond to MCP initialize
before stdin closes, which requires starting before slow DB ops.

Previously these functions only filtered by project when explicitly
passed. Now they auto-detect from CWD using detectProjectFromCwd(),
matching the behavior of project_context.
