+# Decisions — February 2026
+
+## 2026-02-09: Memory System Setup
+- **Decision:** Implement Supermemory.ai backup with automated cron job
+- **Reason:** Need cloud backup for disaster recovery
+- **Status:** ✅ Active
+
+## 2026-02-12: Workspace Context System
+- **Decision:** Create `workspace-context.md` for daily temp state
+- **Reason:** Survives session crashes, cleared daily
+- **Status:** ✅ Active
+
+## 2026-02-14: OpenClaw Reset Recovery
+- **Decision:** Roll back to v2026.2.9 to fix Discord bug
+- **Reason:** v2026.2.12+ broke session keys
+- **Lesson:** Gateway state (cron jobs) != workspace files
+- **Status:** ✅ Resolved
+
+## 2026-02-15: Worker Agent Pattern
+- **Decision:** Create template-based worker agents with HEARTBEAT.md
+- **Reason:** Self-directed agents following routine checklists
+- **Status:** ✅ Active
+
+## 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
+- **Decision:** Strict 1500 char limit, bullet style, no F1 spoilers
+- **Reason:** Consistent formatting, user watches races delayed
+- **Status:** ✅ Locked
+
+## 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
