Two streams. One signal.

DROPS DIRECTLY INTO CORBEAUSPLAT AS THE POST-BRUSH STEP. Brush handles cleanup but no collision, no LOD, no decimation. SplatTransform replaces or augments Brush: GPU floater filter -> progressive merge decimation -> Morton reorder -> export GLB/SPZ/Voxel. CorbeauSplat output gains a free collision mesh, which unlocks every downstream interactive deliverable. CRITICAL FOR BUILDING C PHASE 5 TRACK 2: the callout/measurement UX previously requiring Nira (paid) now works against any glTF viewer using SplatTransform's collision output as click-target geometry. Combined with Cesium plan, Building C exterior gets render + collision-backed callouts + LOD streaming on a $0 SDK stack. Materially shifts Track 2 economics. PRICING: don't pass savings to client — capability is the pitch.

Cluster (sim 0.70 to FreeGaussian 423985f6, sibling Vision3D 56bf5ef7, 360-drone cluster 8c525ba4). PRICING/POSITIONING signal: $200-500/property Matterport workflow now phone-app-table-stakes. CAVU's site-twin pitch must differentiate on quality + integration (measurement, callouts, BIM-via-APS, Cesium delivery), NOT raw 3D-tour-from-iPhone.

Cluster (sim 0.74 to FreeGaussian 423985f6; sibling d98dea07 Cesium, 35ac78fa Moonlake, 97b02e07 SceneMaker — 6+ in 14 days). NEW signal: composition + multi-splat scene editing + web-publish all in one tool — closes capture-to-deliverable loop. Sits between FreeGaussian (capture-only) and Cesium (delivery-only). Open question: real+synthetic splat mixing for proposal pre-viz.

Cluster MEMBER (parent iPhone-only 3D tour scanner, om_patel5 source, May 3 — same underlying tool, similarity >0.81; siblings RohanMital2 maker post + TimJayas use-case). NEW signal: 24h multi-language amplification velocity — phone-3D becomes table-stakes faster than expected.

Cluster PARENT-IDENTITY (parent iPhone-only 3D tour scanner, om_patel5 source — same underlying tool; similarity >0.85). NEW: tool name + AI model name + splat substrate (World Labs) all confirmed. World Labs = new vendor on the watch list.

DIRECT FIX for Building C interior 0%-alignment failure (memory building-c-realityscan-vagon-handoff). Likely path to Phase 5 Track 2 deliverable.
