X_ROADMAP_MILESTONE_UNTRACKED
Means
a milestone row exists that REQUIRED_ARTIFACTS has no entry for, so its status marker verifies nothing
Typical cause
a milestone appended to the table without teaching the checker what shipping it means — the row could then carry ✅ forever with no artifact behind it
Fix
add an entry for that milestone to REQUIRED_ARTIFACTS in scripts/roadmap.ts, then bun run scripts/roadmap.ts --json
