Legitimate code. Now launch the blind validator subagent.

**APPROVED**. Let me verify the validation file exists and update state.

**Phase 7 — Push and create PR.**

Pushed cleanly, rspec (changed files) passed. Now create the PR.

Only the warning was captured — the JSON went elsewhere. Let me retry directly.

All 8 phases complete. Note: per skill constraints, `resolution: pr_created` on the cluster file is
