* - getMilestoneFromPhaseId

// ─── #3412 shared test helper ─────────────────────────────────────────────────
//
// phase-id.cts now delegates regex escaping to RegExp.escape via src/pattern.cts.
// RegExp.escape is MATCH-equivalent to the retired hand-rolled escaper but not
// TEXT-equivalent (it hex-escapes the first character and all hyphens), so any
// test that pinned the literal source text (e.g. `'0*29'`, `'PROJ-42'`) is
// brittle to that internal encoding, not to actual behavior. `headingRegex`
// (imported above as `buildPhaseHeadingRegex` from gsd-core/bin/lib/roadmap.cjs)
// is the SAME production function src/roadmap.cts's searchPhaseInContent uses to
// build its heading regex — not a hand-duplicated copy — so tests assert what
// matches and what doesn't — the real contract — rather than the escaper's
// spelling, with no parity gap against the production pattern.
