/**
 * heal/_vc6c-impl-fixture.ts — conformance fixture I/O for VC6C-IMPL
 * self-healing-controller rows.
 *
 * VC6C's base corpus lives under `healing-controller/` (read by
 * `_repair-fixture.ts`); VC6C-IMPL emits its six fixtures under
 * `self-healing/` per the sprint brief. Both share the one canonical
 * `healing-controller-fixture.schema.json`, so this loader reuses the
 * `RepairFx` envelope (`_repair-fixture.ts`) but resolves fixture paths from
 * the `self-healing/` directory. No mocks — the committed fixtures are fed
 * verbatim into the real heal / reconstruct production modules.
