+# Three-auditor panel + fix loop
+
+**Runtime: droid** (+ the `no-mistakes` CLI). Not Command Code.
+
+When auditing a list of checks:
+
+1. **One shared prompt per check** (scope, intent, deliberate decisions, non-goals).
+2. **Three seats, concurrent:** buggie · no-mistakes · ponytail ultra  
+   (launch buggie and ponytail via **`droid exec`**; no-mistakes via `no-mistakes axi run`).  
+   Skills may be operator-local; see `auditor-loop/AUDIT_PANEL.md` for the full local protocol.
+3. **Synthesize → fix** agreed majors (verify before/after).
+4. **Residual re-audit with droid** (same check, residual brief) — not `./auditor-loop/run.sh`.
+5. **Repeat triad + droid residual** on the **same** check until no major issues.
+6. **Only then** start the next check. Never fan out (N × 3) in one blast.
+
+```text
+for each check:
+  while majors remain:
+    droid(buggie) + no-mistakes + droid(ponytail ultra)  (wait)
+    fix
+    droid residual → fix
+  next check
+```
+
+Full protocol: local `auditor-loop/AUDIT_PANEL.md` (often git-excluded).
+
+**no-mistakes** needs a feature branch with real commits ahead of `main`. Same tip as main → skipped steps, not acceptance.
