/**
 * Tests for verification-status module (issue #651).
 *
 * Covers:
 *  1. status: passed → routing
 *  2. status: gaps_found with phase token extraction
 *  3. status: human_needed → routing
 *  4. No *-VERIFICATION.md → 'missing'
 *  5. Frontmatter status present but unknown value → 'unknown'
 *  6. BROAD-GREP REGRESSION: body `status:` lines ignored, frontmatter wins
 *  7. PARITY: VERIFIER_STATUSES covered by routing table; gsd-verifier.md emitted statuses covered
 *  8. CRLF line endings in frontmatter
 *  9. Body-only file (no frontmatter block) → missing
 * 10. Nonexistent phase directory → missing
 * 11. Multiple *-VERIFICATION.md files → first by sort
 * 12. ship.md PHASE_VERIFICATION_INCOMPLETE sentinel (contract anchor for #651 consolidation)
 *
 * PORTABILITY: pure JS — no shell-outs, no bash fences.
 * Cross-platform (passes on Windows). Ref: DEFECT.TEST-SHELL-PIPELINE-NONPORTABLE.

//
// `src/verification.cts` stored and synthesized hard-coded `/gsd:…` strings with
// no runtime context, and `phase complete` relayed that raw field straight into
// its verification-blocked error. On a Codex project the suggested next step was
// `/gsd:execute-phase`, which Codex does not install — the surface there is
// `$gsd-execute-phase`. The colon form is doubly wrong: `runtime-slash.cts`
// documents that "the colon form is never emitted", so every runtime was getting
// a deprecated shape. (The 11 `/gsd-…` assertions above were `/gsd:…` before this
// fix — they are the failing-first record.)
//
// The fix keeps ONE routing seam and makes its emitted command runtime-aware:
// the table stores bare command names and every return path projects through
// `formatGsdSlash`, with callers passing `resolveRuntime(cwd)`.
//
// Coverage is the matrix the issue asked for — missing, unknown, gaps_found and
// stale, against Codex (`$gsd-…`) and a slash-hyphen runtime (`/gsd-…`) — plus
// the `phase complete` error path, not merely the router's return object.
