/**
 * 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, none matching the phase's own token →
 *     alphabetically-first FALLBACK wins (the phase-pinned rule's #2 tier —
 *     see #3492 below for the primary, phase-pinned tier)
 * 12. ship.md PHASE_VERIFICATION_INCOMPLETE sentinel (contract anchor for #651 consolidation)
 * 13. #3357/#3492: `<phase-token>-VERIFICATION.md` resolution — resolveVerificationFile
 *     unit coverage plus behavioral tests through readVerificationStatus and
 *     findStaleVerificationSummary. THE CONTRACT (#3492): a candidate whose
 *     name exactly matches THIS phase's own token always wins, even over a
 *     different phase's canonically-shaped file; alphabetical-first among all
 *     dashed candidates is only the fallback when no exact match exists. The
 *     resolveVerificationFile unit tests are the reliable anchors for this —
 *     the readVerificationStatus/findStaleVerificationSummary behavioral tests
 *     are illustrative (their outcome also depends on directory-basename
 *     token derivation, not exercised in isolation there).
 *
 * PORTABILITY: pure JS — no shell-outs, no bash fences.
 * Cross-platform (passes on Windows). Ref: DEFECT.TEST-SHELL-PIPELINE-NONPORTABLE.

// A phase dir can legitimately hold more than one `*-VERIFICATION.md` — the
// real per-phase report (`03-VERIFICATION.md`) alongside an ad-hoc plan
// worksheet (`03-CORRECTION-VERIFICATION.md`). The original "alphabetically
// first" pick chose the worksheet ('C' < 'V'), and a worksheet with no
// frontmatter `status:` made the whole phase read `missing` even though a
// passing report sat right next to it (#3357).
//
// #3492 REGRESSION this block anchors: the #3357 fix's first cut preferred
// ANY canonically-shaped `<token>-VERIFICATION.md`, regardless of WHOSE token
// it carried — so a stray cross-phase or sentinel-numbered canonical file
// (`999-VERIFICATION.md`) could outrank the querying phase's own (possibly
// non-canonical) report. THE CONTRACT (verified against the built lib):
//   ['12-review-VERIFICATION.md', '999-VERIFICATION.md'] resolves to
//     '12-review-VERIFICATION.md' for phase token '12' (was '999-…').
//   ['03-CORRECTION-VERIFICATION.md', '04-VERIFICATION.md'] resolves to
//     '04-VERIFICATION.md' for phase token '04' (was '03-CORRECTION-…').
// resolveVerificationFile is the single resolver findStaleVerificationSummary,
// readVerificationStatus, commands.cts's determinePhaseStatus, and both
// init.cts verification_path projectors all call, every one pinned to its own
// phaseDir's token (#3473 F2 / #3492).
//
// These resolveVerificationFile unit tests are the RELIABLE ANCHORS for the
// phase-pinned rule (a real `phaseToken` string, no filesystem/readdir order
// involved). The readVerificationStatus/findStaleVerificationSummary
// behavioral tests further down are illustrative only — their outcome
// additionally depends on the temp directory's basename tokenizing the way
// the test expects.

// ─── #2617: next_command runtime projection ──────────────────────────────────
//
// Regression tests for #2617 — verification-status `next_command` bypassed the
// runtime command-surface projection.
//
// `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.
