// #3804 — audit-uat must see all three phase-archive layouts.
//
// listArchiveVersionDirs matched exactly one layout
// (`milestones/vX.Y-phases/<dir>/`). Two workstream layouts missed:
// archived workstream milestones (`milestones/ws-<slug>-<date>/phases/<dir>/`)
// and active workstream milestones
// (`workstreams/<ws>/milestones/vX.Y-phases/<dir>/`) — so a project using
// workstreams got an "All Clear" audit while items were open (the reporter's
// repo: 20 hidden phase artifacts), and `--ws` emptied the report entirely.
