C3c COMPLETE at 529e0e9d in the placement-cutover plan (five fix slices,
R1 dual-review round, final gates). New closeout research note. ISSUES
#276 (settle-CellId discard), #277 (route-1 far-Create radius bound),
#278 (user-session triage bundle). Register AD-60/AD-61 numeric order.
The next slice before C5 is the 6b28ff99 O(changed) collision clone
(soak convergence); C4 resumes after.
