+**C5 COMPLETE — the placement campaign is FULLY CLOSED (`addb5657`,

+AP-1/AP-145 (closing #318); C5b closed #275 and filed AP-147/AP-148; C5c's
+closeout passed its 11,196-test automated gate and the owed connected-gate
+batch USER-PASSED 2026-08-07. #280's portal-prefetch fix and its dual
+review also landed (AP-149/150/151), and AP-22 retired 2026-08-06. Start

-**Read `docs/research/2026-08-05-c4-closeout-handoff.md` before any C5 or
-placement work.** It carries the four gate recipes, what C5 inherits (#318's
-composition test and its discriminating assertion, AP-145, the #276/#277
-remainders, the probe-family strip), and seven process findings with commits
-attached. The two that cost the most this campaign: a contract asserting a
-mechanism that does not exist caused three separate defects, and inferring a
-fact you can observe made one fix strictly worse than the bug it replaced —
-it removed the invariant failure while leaving the bug. Next: C5 (delete the
-superseded legacy paths, retire AP-1/AD-1, parity tests), then #280, AP-22,
-AD-10.
