+
+## Human steps observed
+
+| Step | Old flow | This run |
+|------|----------|----------|
+| Goal | yes | yes (1) |
+| Wait Plan Mode confirm | yes | **no** — plan.yaml Artifact direct |
+| Mode switch to coding | yes | **no** |
+| Mid-build confirmations | often | **no** |
+| Final Approval | yes | pending (READY_FOR_APPROVAL) |
+
+## Artifact sufficiency
+
+- plan.yaml: scope + acceptance + risks — Builder did not re-ask "how to change"
+- diff.patch: produced via git
+- Gate: first BLOCK (ART-BD-002 Status format + TR-COMMIT) → fix → PASS (valuable FAIL signal)
+
+## Adapter note
+
+execution.adapter=none (in-session Agent as executor with execute prompts).
+cursor_cli supervised available; not invoked live this run to avoid long agent -p cost.
