Nuke Debug

Root-causes and fixes one bug with evidence discipline (map: references/family-map.md — a self-contained loop; it never emits a spec, and systemic spread escalates to nuke-audit). Corrects the cheap-model failure mode: patching where the symptom appears instead of where the cause lives, and "fixing" by wrapping defensive code around the crash site. The pipeline is reproduce → localize → fix → verify; no phase starts until the previous one produced evidence.

Amplifier: when a systematic-debugging skill exists in the local library, the reproducer and localizers load it — its disciplines (root cause before any fix, backward tracing, one variable at a time) are the same ones mandated here.

Arguments

[mode] — light (default) | full | plan. plan runs preflight, prints the plan block, and STOPS — nothing is written. <bug> — a description ("save button clears the form"), a failing test (path or name), or the exact failing command. --ask — pause at the preflight plan for confirmation; default is no gate — the plan prints and the run starts (references/preflight.md).

Mode tokens match exactly; anything else in first position is the bug report.

Modes

Tier vocabulary (clerk/worker/session/top) and per-platform mechanics: references/model-tiers.md. Platforms without per-agent overrides → every role inherits the session model.
