+Clock-only A/B/A separates route effects from scene processing: SSH/Tailscale48/96,
+strictly host-key-pinned SSH over confirmed LAN94/96 (only initial2 unready), return
+to Tailscale53/96. All288 exchanges reconstruct; application handler/loop delays do
+not alone explain ~100ms request tails. LAN is an observed connection option, not
+a new model dependency, universal speedup or permanent product/default route change.
+
+One full LAN canary returns32/32 byte-exact/reference-exact scenes at1x with no WAIT,
+drop or reconnect;50 clock exchanges reconstruct,48 after initial warmup remain ready.
+All129 prior runtime source files and the model/effective config remain unchanged.
+Latency205.864/213.751ms p95/p99 still fails125ms; only12/32 scenes are fully fresh.
+Do not equate complete output accounting with usable geometry/policy or autonomous
+readiness. Next instrument data-plane stage boundaries before optimizing remaining
+tails; no gate widening.245 local/202 Worker tests PASS,131 source hashes matched.
