FI geometry v3 drops the all-XY lower boundary seal that created false floors (3.5/8 m); the ceiling comes from the shared VF_ApplyUpperBoundarySeal and AppendStratumBoundaryCeilings path for every generator, at each strate's own configured upper boundary (owner: every strate has a ceiling). Far-LOD ceiling continuity: 0 gaps at LOD4-8. SurfaceWorld bit-identical to L14 (14 configs + 24 m crossing); FI deterministic (28-row matrix); route parity and proofs pass. Unreal: FI geometryVersion 2->3 and the shared upper-seal helper extracted (UBT compile needed on the owner PC). Open: small ceiling holes; lower-stratum LOD ring steps seen through the FI void.
