/**
 * `debug.md` Step 0 contract after the `init.debug` consolidation (#3149).
 *
 * Matrix: `.gsd/phase/feat-3149-cmdinitdebug/50-test-matrix.md` group F.
 *
 * Guards the four ways this consolidation can silently regress:
 *   F1/F2 — a replaced round-trip creeping back, or the new one being lost.
 *   F3    — reading `config.response_language` (the nested state.load shape)
 *           instead of the flat top-level field withProjectRoot injects. This
 *           is the #2402 defect class: the workflow silently stays English.
 *   F4    — losing the `@file:` unwrap, which large init payloads still need.
 *   F5    — dropping the `section_manifest: null` -> read-everything rule,
 *           without which a null manifest reads as "read nothing".
