- **Status:** ✅ Active

## 2026-02-12: Workspace Context System

- **Status:** ✅ Active

## 2026-02-14: OpenClaw Reset Recovery
- **Decision:** Roll back to v2026.2.9 to fix Discord bug

## 2026-02-16: Hybrid Memory (File + DB)
- **Decision:** Keep human-readable files + structured SQLite database
- **Reason:** Best of both worlds — readable and queryable
- **Status:** ✅ Active

## 2026-02-17: News Brief Format Lock

## 2026-02-17: Context Limit Fix
- **Decision:** Manual file chopping when /compact fails
- **Reason:** Coding sessions bloat fast, terminate doesn't work
- **Method:** Delete first 50% of session file, keep recent context
- **Status:** ✅ Documented

## 2026-02-18: Hierarchical Memory System — COMPLETED ✅

**Decision:** Implement ucsandman's hierarchical memory system (index + drill-down)
**Reason:** Flat MEMORY.md doesn't scale (5-10k tokens). Need 60-70% token reduction.
**Implementation:** 
- Created memory/people/, memory/projects/, memory/decisions/
- Rebuilt MEMORY.md as ~2.4k token index
- Added trigger words, drill-down rules, integration table
**Result:** 
- Session start: 5-10k → 2.4k tokens (70% savings)
- On-demand drill-down: ~1k per file (only when mentioned)
**Status:** ✅ LIVE — Major architecture milestone
**Files:** MEMORY_MIGRATION_LOG.md, WORKSPACE_STRUCTURE.md
