Audited all 10 active plan docs against the codebase (not just commit
titles). 5 were fully shipped and stale-tagged "Planned"/"In Progress" —
moved to done/ with verification notes. The other 4 got corrected
Planned→In Progress status plus concrete remaining-gap notes so the next
pass doesn't re-derive what's already done.
