//
// The guard that refuses to archive a milestone while the ROADMAP still lists
// unstarted phases used to nest its entire ROADMAP scan inside
// `if (stateVersion && stateVersion === version)`. Any STATE.md `milestone:`
// value that did not exactly string-equal the version argument — a desynced
// value, or no `milestone:` field at all — skipped the scan with no warning,
// functionally equivalent to an implicit `--force`. The operation the guard
// fronts is a one-way door: ROADMAP.md and REQUIREMENTS.md are archived and
// phase directories are MOVED into `.planning/milestones/<version>-phases/`.
//
// The scan was already driven by the `version` argument through
// getMilestonePhaseFilter / extractCurrentMilestone; the STATE match was a
// redundant second gate that shadowed and broke it. After the fix the scan
// runs whenever `--force` is absent and the ROADMAP can be scoped for the
// version; a present-but-mismatched STATE.md `milestone:` field additionally
// emits a WARNING naming both values.
