artifact-store publish (metrics publish), activity-core ActivityDefinition
references, integration patterns docs, and canon/knowledge design artifacts.

+#### Worked example
+
+A TDD8 session captured by Helix Forge and closed with kaizen metrics:
+
+```bash
+# Helix capture sets (or operator exports) session identity
+export HELIX_SESSION_UID="claude:17092961-abc"
+export HELIX_REPO="kaizen-agentic"
+export HELIX_FLAVOR="claude"
+export HELIX_TOKENS="12500"
+
+# Session close — project layer
+kaizen-agentic metrics record tdd-workflow --success --time 4200 --quality 0.92
+
+# Inspect project record (includes correlation fields)
+kaizen-agentic metrics show tdd-workflow
+
+# Fleet lookup — read-only, no ingestion in kaizen-agentic
+export HELIX_STORE_DB=~/.helix-forge/store.db
+kaizen-agentic metrics correlate claude:17092961-abc
+```
+
+Project `executions.jsonl` carries `helix_session_uid` for audit; fleet analytics
+remain in agentic-resources digest store. Coach `memory brief` surfaces project
+`## Performance Summary`; correlate adds fleet context when needed.

-Example ActivityDefinitions (after metrics CLI ships):
+ActivityDefinition reference copies (sync into activity-core to activate):
 
-- Weekly: run `kaizen-agentic metrics optimize` on repos with `.kaizen/`
-- On low success_rate threshold: create review task in issue-core
-- Post agent install: verify metrics scaffold exists
