The first deliberate flags-off baseline change. On D's GO (43edabf: E1 ped sub-mesh merge
447188a validated → ~1 draw/near-rig → full density 241 worst-street draws <=300, leak-free).
index.html: chunk-streamed roster default-on (chunkStream:{radius:2}); ?roster=v1 restores the
old fixed roster (escape hatch); ?roster=stream still accepted (now a no-op). Hours-aware
setNightLivelyChunks keeps the open-late block lively at night.
Flags-off regression baseline RE-PINNED (same commit, prime-law amendment):
OLD (roster-off, v1.1): 163 draws, 19000 tris
NEW (roster default-on, R7): 164 draws, ~66000 tris
Draws barely move — E1's merge makes each near-rig ~1 draw (exactly what gated the flip). The
tris jump is the streamed crowd (D worst-view 65,899); it is frame-variable, so the drift WARN
is now DRAWS-ONLY, tris guarded by the STREET_TRIS_MAX hard cap. PLAN GOLDENS UNCHANGED
(synthetic 0x3fa36874, osm 0x34cfdec0).
Also fixed the harness roster probe (read a nonexistent prop c.streaming → was blind to
streamMode) + flipped the assertion to REQUIRE streamMode on default boot + added a ?roster=v1
escape-hatch check. flags_check GREEN; qa.sh --strict green; 0 console errors both modes.
