-**Status:** OPEN
+**Status:** CLOSED 2026-08-24 — owner-accepted in both presentation modes
+("Feels good capped too"). Fixed across three commits: `0330fcd0`
+(allocation-exact streamed-mesh completion), `4873c106` (presented
+player + chase camera share the object clock), `ad695589`
+(allocation-free shadow topology rebuild + churn-frame pipelining).
+Final measured state: stall frames 5.8/s → ~0.45/s uncapped (0.49/s
+capped), median stall 20.3 → 13.7 ms, camera-vs-player decoherence
+~1 m → 0.2–1.2 cm median. Residual content-proportional rebuild cost is
+the incremental-topology successor campaign; the town-view latch found
+during measurement is #432.
