/**
 * audit-floor (CUT A4) — the audit warning-floor gate as a finite, structured
 * command (migrated from `scripts/audit-floor.ts`). It fails when the
 * artifact-independent three-pass warning inventory drifts from the pinned
 * `AUDIT_WARNING_FLOOR`, or when ANY error-severity finding is present.
 *
 * The engine (`@czap/audit`'s structure/integrity/surface passes) is INJECTED via
 * `context.runAuditFloor`, never imported here, so `@czap/command` (and the MCP
 * server that re-uses it) stays free of the TypeScript-compiler/fast-glob audit
 * engine. Unlike `plumb`/`check-invariants` (whose scans are pure `node:fs` and
 * are provisioned in the shared host factory), this gate rides the HEAVY
 * `@czap/audit` engine — exactly like `audit` — so it is CLI-only and NOT
 * MCP-exposed: only `@czap/cli` injects `runAuditFloor`, and over MCP the command
 * degrades to a structured `capabilityUnavailable` failure.
