Use when the user asks for a deep, exhaustive, multi-pass, or variance-reducing repository-wide Codex Security scan. Run repeated independent repository-wide discovery passes with worker-specific threat models, semantically merge candidates, synthesize one canonical validation threat model, then run validation, attack-path analysis, and final reporting once. Repository-wide targets only; do not use for PRs, commits, branch diffs, working-tree diffs, or scoped paths.
