wip: cave planner route support fixed (L134 design 3); clearance at edge joints open

Arrival edge floor aligned to the passage mouth, 0.75 m backbone floor-support budget, anchors on the planned floor:
0 unsupported, 0 grade failures. Open: 196/50,967 capsule samples blocked where a higher descending edge's floor
backing meets the next edge (route-edge-6/7).

 # Linux134 — Tunnel Network cave planner
 
-The second design fixed the incoming passage at its source. Native cave composition already called the shared passage composer, but that composer skipped passages whose lower layer used `hasNativeCaveField`. Removing that skip lets the passage field join the cave field through the boundary and also applies to native lattice layers. Tunnel Network dispatches `Caves-native` (`Core.Caves.PrimitiveField` v1).
+Tunnel Network dispatches `Caves-native` (`Core.Caves.PrimitiveField` v1). The seed-0 plan is strict-valid: 30 compound rooms, 72 primitives, 31 edges, 3 side branches, and one larger destination chamber. The arrival-to-departure route is 387.067 m long, has a 59.021 m floor delta, and reaches 8.670° maximum grade. The planner maps 21 of the 47 legacy generation fields; the other 26 do not map to resolved room or edge record fields.
 
-The seed-0 plan is strict-valid: 27 route nodes, 72 primitives in 30 compound rooms, 3 branches, 31 edges, and a 6.75 m destination chamber. The route is 387.067 m long with 59.021 m floor delta and 8.670° maximum grade. The passage centerline check now passes 21,425/21,425 samples. All three passage interfaces, shell/floor, ripple, and blocked controls pass.
+The second design fixed the incoming passage at its source. Shared passage composition now applies passages when the lower stratum has a native cave field; the unchanged walkability audit passes 21,425/21,425 samples.
 
-**Stopped at the Tunnel Network route-support gate.** `ResolvedStrateRouteAudit` reports 0 blocked capsule samples and 0 grade failures, but 380 unsupported samples. The first support failures are just inside the arrival mouth at `(19.166,-14.650,-754.254) m`, then `(19.080,-15.135,-754.327) m` through `(18.909,-16.106,-754.473) m`. Another failing sample cluster starts at `(17.364,-24.839,-755.788) m`. Overall: 795 center samples, 6,957 support probes, `mouth_binding=PASS`, `status=FAIL`. The arrival-to-departure route is therefore not yet walkable under the support audit. I stopped before the remaining bar.
+The third design aligned the arrival-edge floor to the passage mouth, added a 0.75 m backbone floor-support budget to the resolved edge records, and raised route anchors to follow the planned edge floor. The route audit now reports 0 unsupported samples and 0 grade failures. It still fails clearance: 196/50,967 capsule samples are solid. The first is `(-14.548,-104.858,-768.115) m`, density `-0.042135`, at the route-edge-6/7 junction. Its closest planned floor is route-edge-6 at approximately `z=-768.104 m`; the probe is about 1.1 cm below that floor. The player center interpolated along the next route segment is only about 0.79 m above this higher neighboring floor, while the capsule samples extend 0.84 m below center. The native field is returning the intended solid floor backing, which intrudes into the capsule near the overlapping descending edges. The remaining issue is clearance planning across neighboring edge floors, not missing floor support, a room floor cut, or the inter-strate passage.
 
-The planner maps 21/47 legacy fields into room/edge records: `RoomSpacing`, `RoomDensity`, `MinRoomRadius`, `MaxRoomRadius`, `RoomHeightRatio`, `RoomFloorCutMin`, `RoomFloorCutMax`, `RoomShapeVariety`, `OriginRoomRadius`, `OriginRoomMaxConnections`, `TunnelMinRadius`, `TunnelMaxRadius`, `TunnelDensity`, `MaxTunnelLength`, `TunnelWarpStrength`, `TunnelHorizontalBias`, `bTunnelsFlowTowardOrigin`, `CaveWarpStrength`, `SurfaceRoughness`, `RoughnessFrequency`, and `SDFBlendRadius`. The other 26 do not map: `BaseDensity`, `BoundarySealThickness`, `CaveWarpFrequency`, `DomainWarpFrequency`, `DomainWarpStrength`, `FloorBias`, `FloorReliefFrequency`, `FloorReliefStrength`, `RoomMouthRiseBlendVoxels`, `RoomMouthRiseStrength`, `TunnelEndpointZOffset`, `TunnelFloorGentleSlopeThreshold`, `TunnelFloorLedgeCountPreference`, `TunnelFloorMaxLedgeHeight`, `TunnelFloorMaxLedges`, `TunnelFloorTerraceStepHeight`, `VerticalScale`, `WaterLevelRelative`, `WormFrequency`, `WormHorizontalBias`, `WormNetworkRange`, `WormStrength`, `WormThreshold`, `bTunnelFloorEnabled`, `bTunnelFloorTerracingEnabled`, and `RoughnessNoiseType`.
+I stopped at this failed route gate, as requested. Shell, floor, ripple, and blocked-route negative controls pass; the route's blocked control also detects the blockage.
