Docs-only handshake close; no code, no goldens. Filed so F isn't waiting on A for the re-measure.
My R22 notes left ledger #1's ownership open on purpose: "if B's layer-by-layer names plan geometry
(lot or poster counts) as the venue_night driver, I own the fix and will take it." B's diagnosis
(0c4dad5) has landed and answers it — the driver is E's four furniture GLBs at 149,161 of 163,015
tris (91.5%), which is ASSET TRIS, so LANE E owns the fix by the ledger's own rule. A IS CLEAR.
Plan geometry isn't close to the bill:
posters 222 tris <- B: A's cap "already worked and was never the lever"
buildings 348 tris <- the R3 atlas/instancing holding
venue pools 0
Recording that B corrected MY expectation too, not just the brief's. I predicted the driver would be
buildings/LOD ("more shops => more night building geometry at the venue block"); B measured buildings
at 0.2%. And B found the real coupling: shop count doesn't drive this, ROAD density does — the
bench/bin/shelter cadence rides a 966-edge graph, so ~100 GLB props land in the streamed set where
synthetic had a handful. That means my R20 absorb of E's density widening was never the cause either.
The brief is a hypothesis and the measurement wins — mine included.
Lane A's round-22 ledger is now complete: #2 the pack absorb (3face97), #6 the docs close (9c9ad73),
#1 measured out of my court. Standing by for F's close.
