// #1729 regression: a phase header may carry a parenthetical tag BEFORE the
// colon — `### Phase 26 (Cluster B): Title`. The header regexes built
// `Phase\s+<num>` immediately followed by the colon delimiter, so the resolver
// returned found:false and phase commands silently no-op'd (the failure is
// silent — not-found, not an error — so an author can lose work without a
// signal). The fix injects a shared OPTIONAL_PHASE_TAG_SOURCE fragment at every
// header call site, mirroring how `[...]` is already tolerated before `Phase`.
//
// Parity assertion (per the #3537/#3599 generative-fix discipline): a pre-colon
// tag must resolve the SAME phase as the equivalent post-colon tag, padding
// tolerance must survive, and the optional tag must not enable cross-phase
// false matches. A shared seam + parity test keeps the next call site from

/**
 * Run `gsd-tools phase complete <phase>` for the phase-complete regression
 * suites and return its stdout.
 *
 * `phase complete` writes ROADMAP.md as its LAST step, after a read-heavy
 * parse/lock sequence (ROADMAP read, two extractCurrentMilestone STATE.md
 * parses, REQUIREMENTS read, phase-dir scan, STATE read — all before the single
 * writePlanningFileSet flush). Under the high-concurrency docker run (~672 test
 * files in parallel), a tight 10s timeout could fire mid-parse and SIGTERM the
 * subprocess BEFORE that write landed, leaving ROADMAP.md untouched. Call sites
 * that used a bare `catch {}` then silently proceeded to assert on the pristine
 * file — an intermittent "checkbox not checked" failure (bug #1998 flake).
 *
 * Two-part fix, no retry loop:
 *  1. A generous timeout so the test's own timer never kills the subprocess
 *     under load (10s cold-node startup × 672-way CPU/IO contention was the
 *     real culprit — all I/O is scoped to tmpDir, so there is no cross-process
 *     race to blame).
 *  2. Never silently swallow a signal/timeout kill: it means the process was
 *     terminated before completing its writes, so we surface it loudly with
 *     context instead of letting it masquerade as an assertion failure. A

 *   **Requirements**:          colon OUTSIDE bold delimiters
 *   **Requirements** :         space-then-colon outside bold
 *
 * Two parsers in the codebase used opposing strict regexes — one only
 * matched the outside-colon form (init.cjs / init.ts), the other only the
 * inside-colon form (phase.cjs `cmdPhaseComplete` REQUIREMENTS.md
 * traceability sweep). Both must accept all three variants so phase
 * metadata propagation is robust to authoring style.
 *
 * Tests for the init query side live in `tests/init.test.cjs` (parameterized
 * over the three variants). This file exercises the inverse bug in
 * `phase complete`: the REQUIREMENTS.md checkbox must flip when ROADMAP
 * uses the outside-colon form, which previously was silently skipped.

/**
 * Regression tests for bug #3537
 *
 * Phase state verbs must match a canonical phase id against ROADMAP.md prose
 * regardless of zero-padding on either side: the skills pass the padded form
 * (`02.7`) after resolving the phase directory, but human-authored ROADMAP
 * prose is conventionally un-padded (`### Phase 2.7:`, `- [ ] **Phase 2.7:**`).
 *
 * v1.42.1 added `phaseMarkdownRegexSource()` which renders `0*<integer><...>`
 * — padding-tolerant on both sides — but wired it into only 1 of 8 call sites.
 * The other 7 used raw `escapeRegex(phaseNum)` or `0*${escapeRegex(...)}`
 * (tolerated extra padding, not missing), so passing the padded form silently
 * no-op'd and the verbs returned success while ROADMAP.md was unchanged.
 *
 * Parity assertion (per CONTEXT.md DEFECT.GENERATIVE-FIX): for each verb,
 * running with the padded form must produce the same ROADMAP.md as running
 * with the un-padded form against an identical fixture. Per-site fixes
 * without a parity test let the next call-site drift back undetected.

/**
 * Regression test for issue #4 (open-gsd/gsd-core):
 *   bin/lib/phase.cjs cmdPhaseComplete — non-idempotent and unclamped.
 *
 * Root cause (pre-fix):
 *   cmdPhaseComplete blindly increments "Completed Phases" by 1 on every call
 *   (parseInt(completedRaw, 10) + 1) and recomputes Progress without a clamp.
 *   Double-calling yields Completed Phases +2 (not +1), and Progress can exceed 100%.
 *
 * Fix: derive completed_phases from ROADMAP Complete-row count (idempotent) and
 *   clamp percent to 100. This mirrors the SDK fix in phase-lifecycle.ts
 *   (commit deriving from ROADMAP, referenced as "PR #3520" in issue #4).
 *
 * Note on test structure: phase-command-router.cjs delegates to the SDK when
 *   the SDK dist is present, so the CJS path is exercised by calling
 *   cmdPhaseComplete directly (bypassing the router), which is the actual
 *   function containing the bug.
 *
 * References:
 *   - ADR-3524 (docs/adr/3524-cjs-sdk-hard-seam.md) — architectural foundation
 *   - /tmp/adr-3524-review-findings.md — architectural justification
 *   - Issue #4 (open-gsd/gsd-core)

//
// ROADMAP.md may cite a REQ-ID in a phase's `**Requirements:**` line that was
// never registered anywhere in REQUIREMENTS.md (neither its body nor its
// Traceability table). The only existing cross-check compares REQUIREMENTS.md's
// own body against its own Traceability table — it never consults the REQ-IDs
// ROADMAP actually cites — so such a "ghost" REQ-ID is invisible: the checkbox/
// Traceability write for it silently matches nothing, and the command reports
// `requirements_updated: true, warnings: []` identically to a run that wrote
// something real.
//
// Contract asserted by #2316-3: `requirements_updated` reflects whether
// REQUIREMENTS.md's content actually changed (before !== after write), not
// merely whether the file existed in the transaction.
