wip(assembler): round S6 -- in-game cold view counted; workers mostly idle, apply cap not the floor

Direct per-tile trace on the BuildHost actor (owner plan, 2,578 keys): full set
17.4 s legacy; gated coarse-first (after the 9-tile walkable ring) 11.7 s with
the ring still at 0.63 s, but full LOD0 slips 2.3 -> 10.2 s. Startup apply
boost changed nothing (0.4%). 37.6 worker-s over 17.4 s on 10 slots = ~3.3
busy: the floor is admission/work supply. S5's 251 ms staircase was the trace
sampler. Fixed CVar parsing in headless BeginPlay and the 60 m/s crossing
instrument. All three knobs stay opt-in.

+## World assembler S6 / M3 Round 10 — 2026-10-19
+
+The 251 ms staircase was the residency sampler cadence; direct tile apply events are the completion
+clock. The legacy-order control completed the staged 2,578-key set in 17.412 s. Gating coarse-first
+admission behind the nine-tile walkable ring reduced it to 11.704 s without delaying that gate
+(0.632 → 0.627 s). The 12-mesh / 14 ms spawn apply boost did not improve the legacy timeline, so it
+remains opt-in and the normal 4-mesh / 2 ms guard stays in place. Worker-side work supply/admission
+remains the measured floor; the trace does not isolate why worker slots stay idle. The 1.57 s aim is
+still unmet and rendered enclosure remains unproven in the null-RHI harness.
+
+The corrected standalone 60 m/s route now counts +Y crossings across multi-chunk deltas. Its
+crossing data is valid, though the latency gate still fails. W1/W8/W16 and all nine LOD hashes match
+S5. The new trace, regressions, run ledger, exact log-captured command lines, hashes and compile
+spots are in [WorldAssemblerM3/Round10/REPORT.md](../../WorldAssemblerM3/Round10/REPORT.md).
