  1. docs: update README changelog with v1.4.0 + v1.4.1 + v1.3.0, fix tool… 

    … count to 100+

  2. feat: v1.5 improvements — KG search boost, HNSW indexing, modular arc… 

    …hitecture, claim graph, test suite

1. KG-influenced search: memories with more Knowledge Graph connections get a
   logarithmic score boost (0.015 * log2(connections + 1), capped at 0.08).
   Bridges semantic (vector) and structural (graph) retrieval.

2. HNSW vector indexing: optional hnswlib-based approximate nearest neighbor
   search. Activates automatically when memory count exceeds 10K. Falls back
   gracefully to brute-force scan when not available.

3. Modular db.py: extracted 9 sub-modules (db_schema, db_sessions, db_reminders,
   db_learnings, db_credentials, db_tasks, db_entities, db_episodic, db_evolution).
   Original db.py remains as backward-compatible barrel.

4. Modular cognitive.py: extracted 4 sub-modules (cog_search, cog_ingest,
   cog_trust, cog_decay). Original cognitive.py remains intact.

5. Claim graph: atomic claims with provenance, contradiction detection, and
   verification status. Decomposes blob memories into individual verifiable facts.

6. Test suite: 24 pytest tests covering migrations, CRUD operations, cosine
   similarity, KG boost, knowledge graph traversal, and temporal boost.

  3. refactor: modularize db.py and cognitive.py into real packages 

    BREAKING: db.py → db/ package, cognitive.py → cognitive/ package.
All public APIs re-exported via __init__.py for full backwards compatibility.

db/ package (11 modules):
  _core.py      — connection, SerializedConnection, init_db, constants, utils
  _fts.py       — FTS5 unified search, rebuild, synonyms
  _schema.py    — formal migration system (12 migrations)
  _sessions.py  — sessions, file tracking, messages, questions
  _reminders.py — reminders and followups CRUD
  _learnings.py — learnings CRUD and similarity
  _credentials.py — credentials CRUD
  _tasks.py     — task history and frequencies
  _entities.py  — entities, preferences, agents
  _episodic.py  — changes, decisions, diary, archive, checkpoints, recall
  _evolution.py — evolution metrics and logs

cognitive/ package (6 modules):
  _core.py    — DB, embedding, cosine similarity, constants, tables
  _search.py  — search, BM25, HyDE, co-activation, KG boost, HNSW integration
  _ingest.py  — ingest, PE gate, quarantine, security scan
  _decay.py   — Ebbinghaus decay, promotion, GC, dream consolidation
  _trust.py   — trust scoring, sentiment, dissonance
  _memory.py  — format, stats, consolidation, somatic markers

HNSW integration: add_item on ingest, candidate filtering on search,
invalidate on GC/promotion. Activates automatically when >10K memories.

  4. fix: audit fixes + version bump to 1.5.0-beta.1 

    - Fix _model global variable missing in cognitive/_core.py
- Fix quarantine_stats and get_gate_stats cross-module imports in _memory.py
- Fix _INJECTION_PATTERNS missing in _ingest.py (security_scan was broken)
- Update conftest.py for package structure (db._core, cognitive._core)
- Bump version to 1.5.0-beta.1
- Add tests/ to package.json files array
- Update description with knowledge graph + HNSW

  5. feat: v1.5.0 — modular architecture, KG search, HNSW, claim graph, D+… 

    … inbox

Major release with 6 features:

1. MODULAR ARCHITECTURE: db.py → db/ package (11 modules), cognitive.py →
   cognitive/ package (6 modules). Full backwards compatibility via __init__.py.

2. KG-INFLUENCED SEARCH: memories with more Knowledge Graph connections get
   logarithmic score boost (0.015 * log2(conn+1), capped 0.08).

3. HNSW VECTOR INDEXING: hnswlib integration. Auto-activates >10K memories.
   Hooks into ingest (add_item), search (candidate filtering), GC (invalidate).

4. CLAIM GRAPH: atomic claims with provenance, contradiction detection,
   verification status. Tables: claims + claim_links in cognitive.db.

5. INTER-TERMINAL AUTO-INBOX (D+): PostToolUse hook checks inbox via sqlite3.
   2s debounce, skips read-only tools. Zero tokens when no messages.
   claude_session_id tracking in sessions table (migration 13).

6. TEST SUITE: 24 pytest tests — migrations, CRUD, cosine similarity, KG
   boost, KG traversal, temporal boost. Isolated temp DBs per test.

Migration: v13 adds claude_session_id column + index to sessions table.
