type:audit type:review

When the governance machinery itself (the rules, skills, and audit gates that keep a governed codebase honest, plus their wiring surfaces) needs a structural-integrity review, run this skill. It is the periodic guard-rail review: a judgment-based pass over the machinery for overlap (two rules or gates covering the same ground), gap (a stated discipline no gate enforces, a recurring failure mode no rule names), and drift (a rule, skill, or gate whose intent has diverged across its wiring surfaces in a way the mechanical parity gates cannot detect, because they check identity and count, not meaning). Maintainer-triggered, and auto-prompted after any PR that adds, removes, or renames a rule, skill, or gate. Catches the architectural erosion the per-PR and corpus-content sweeps are not built to see. Slash command `/guardrails`.
