+# Agent C — Compiler
+
+## Purpose
+
+Compiles t27 specifications into executable artifacts:

+   - Support agent decision-making
+
+4. **Agent Update**
+   - Propagate learnings to other agents
+   - Update heuristics based on success rates

+  "spec_hash": "<SHA-256>",
+  "test_results": {
+    "passed": <number>,
+    "failed": <number>
+  }
+}
+```
+
+## Tools
+

+- `tri notebook` — Manage NotebookLM memory
+
+## Success Criteria
+
+- Every PHI LOOP cycle is captured
+- Experience retrieval is accurate and fast
+- Agents use experience to improve decisions
+- Semantic search returns relevant past episodes
+
+## Error Handling
+
+- Log experience capture failures
+- Retry failed saves with backoff
+- Maintain backup of experience log
