c29023dd80 feat: Vestige v1.7.0 — 18 tools, automation triggers, SQLite perf 
Tool consolidation: 23 → 18 tools
- ingest merged into smart_ingest (single + batch mode)
- session_checkpoint merged into smart_ingest batch (items param)
- promote_memory/demote_memory merged into memory(action=promote/demote)
- health_check/stats merged into system_status

Automation triggers in system_status:
- lastDreamTimestamp, savesSinceLastDream, lastBackupTimestamp,
  lastConsolidationTimestamp — enables Claude to conditionally
  trigger dream/backup/gc/find_duplicates at session start
- Migration v6: dream_history table (dreams were in-memory only)
- DreamHistoryRecord struct + save/query methods
- Dream persistence in dream.rs (non-fatal on failure)

SQLite performance:
- PRAGMA mmap_size = 256MB (2-5x read speedup)
- PRAGMA journal_size_limit = 64MB (prevents WAL bloat)
- PRAGMA optimize = 0x10002 (fresh query planner stats on connect)
- FTS5 segment merge during consolidation (20-40% keyword boost)
- PRAGMA optimize during consolidation cycle

1,152 tests passing, 0 failures, release build clean.

34f5e8d52a feat: Vestige v1.2.0 — dashboard, temporal tools, maintenance tools, detail levels 
Add web dashboard (axum) on port 3927 with memory browser, search, and
system stats. New MCP tools: memory_timeline, memory_changelog,
health_check, consolidate, stats, backup, export, gc. Search now supports
detail_level (brief/summary/full) to control token usage. Add backup_to()
and get_recent_state_transitions() to storage layer. Bump to v1.2.0.

bbd1c15b4a Add Prediction Error Gating and smart_ingest tool (26 tools total) 
Implements neuroscience-inspired memory gating based on prediction error:
- New smart_ingest MCP tool that auto-decides CREATE/UPDATE/SUPERSEDE
- PredictionErrorGate evaluates semantic similarity vs existing memories
- Automatically supersedes demoted memories with similar new content
- Reinforces near-identical memories instead of creating duplicates
- Adds promote_memory/demote_memory/request_feedback tools

Thresholds:
- >0.92 similarity = Reinforce existing
- >0.75 similarity = Update/Merge
- <0.75 similarity = Create new
- Demoted + similar = Auto-supersede

5337efdfa7 Switch embedding model from BGE to nomic-embed-text-v1.5 
- Replace BGE-base-en-v1.5 with nomic-embed-text-v1.5
- 8192 token context window (vs 512 for BGE)
- Matryoshka representation learning support
- Fully open source with training data released
- Same 768 dimensions, no schema changes required
