Skill audit report

blast-radius-grep Audit report.

The unit of change is the action or the fact, never the named list of places someone handed you. Before shipping a gate, constraint, rename, drop, or a correction to any duplicated, mirrored, or denormalised value, grep the whole repo — app, tests, seeds, scripts, open branches, and the built or rendered output — and fix every occurrence in the same pass; back a value copied into a second store with a trigger and a zero-rows drift-check query. Triggers on "change X in A and B" instructions, constraint or gate additions, drops and renames, denormalising a value, and correcting any fact that is not single-sourced. Does not fire on checking references in prose documents — verified-citations owns citation accuracy; this skill owns content duplication.
