type:audit type:review

Iterative TRIO-debate + fix-wave protocol for hardening non-trivial PRs and changes before merge. Spawns a parallel Reviewer + Auditor + Critic trio, dispatches fix waves, loops until convergence (zero NEW P0 blockers). Use before merging anything with cross-file risk, cross-PR coordination, security-sensitive changes (auth, signing, redaction, prompt-injection defense), schema migrations, production-data touches, shell scripts, CI/workflow YAML, cross-repo coordination, or LLM prompt work — anywhere a silent failure would be expensive. Born from a real project where 7 iteration rounds caught 30+ bugs that solo review would have missed.
