+# 3-Tier Memory System
+
+Inspired by OpenClaw's proactive agent memory pattern. Three tiers serve
+different purposes with different update frequencies.
+
+## Architecture
+
+```
+Tier 1: SESSION-STATE.md (hot)
+  - Updated every turn
+  - Read FIRST on session start and compaction recovery
+  - Contains: current task, decisions, pending actions, working buffer
+
+Tier 2: memory/YYYY-MM-DD.md (warm)
+  - One file per day, auto-rotated
+  - Updated at end of each pipeline run
+  - Contains: daily summary, decisions, files modified, issues, carry-forward
+
+Tier 3: memory/MEMORY.md (cold)
+  - Updated manually or after significant learnings
+  - Read LAST during compaction recovery
+  - Contains: identity, curated learnings, patterns, known issues
+```
+
+## WAL Protocol (Write-Ahead Logging)
+
+Before responding to the user with important information, write it to
+SESSION-STATE.md first. This prevents data loss if:
+- The session crashes mid-response
+- Context compaction removes the exchange
+- The user's connection drops
+
+## Working Buffer Protocol
+
+When context usage exceeds ~60% (the "danger zone"):
+1. Activate the Working Buffer section in SESSION-STATE.md
+2. Copy critical recent exchanges into the buffer
+3. Extract and list key facts that would be lost on compaction
+4. Continue working normally — the buffer is your safety net
+
+## Compaction Recovery
+
+When Claude resumes after context compaction, it reads in this order:
+1. SESSION-STATE.md (current task, decisions, working buffer)
+2. Today's daily log (what happened today)
+3. MEMORY.md (long-term context, known issues)
+4. Search older daily logs if needed for specific context
+
+## Integration with Agent Factory
+
+During `/agent-factory:build` Phase 2.5 (Memory Setup):
+1. Copy these templates to the user's `memory/` directory
+2. Replace `{{PLACEHOLDER}}` variables with project-specific values
+3. Create the initial SESSION-STATE.md and MEMORY.md
+4. Configure the pipeline skill to update daily logs after each run
+
+## File locations after scaffolding
+
+```
+project/
+  memory/
+    SESSION-STATE.md    (from Tier 1 template)
+    MEMORY.md           (from Tier 3 template)
+    2026-04-11.md       (generated daily, from Tier 2 template)
+    2026-04-12.md
+    ...
+```
