+## Part D — operator extension: generic solid sweep + height pass (committed `5382cbf34`)
+
+Operator: "a bunch of items in base/expedition still lack collisions; height pass — nothing should look
+climbable/hilly in a way that lets the player phase through. Commit after verification." Tool extended + re-applied:
+
+- **Generic solid sweep**: every LOD0 visual inside the LOCAL fitted wall that isn't soft flora (regex list:
+  grass/flower/bush/pebble/groundcover/…) and stands ≥0.5 u tall with walk-band geometry gets a walk-band OBB —
+  **85 adds**: cacti, succulents, boulders (`Rock_12`), bone piles, small rocks, **craters as FULL set-piece
+  blocks** (rim mounds read as "hilly"; blocking the whole depression avoids both phase-through and
+  float-over — flag for the feel-lap, rim-gap walkable craters are a possible follow-up), crates, tree trunk,
+  turbine poles, dish, solar rigs. 595 soft-flora + 38 elevated/sub-threshold skipped; **0 too-big items
+  in-play** (all background hills/arches sit beyond the walls).
+- **Height pass**: ring sampling dropped to the ANKLE band (0.45–2.5) — the wall stops the player before any
+  visibly rising skirt (numbers landed identical to torso band: cliff faces are near-vertical at their
+  innermost points); every generated collider's top = the visual's top (floor 0.8, cap 3.0); rings span
+  y −0.5..4.5; elevated-only geometry (rotor blades, panel plates) gets NO ground collider (phantom-wall
+  hazard, caught in design).
+- **Two tool bugs caught by the audit loop**: (1) ring fit read r0 from the CURRENT segments → the window
+  RATCHETS inward every re-run (base drifted 30→25.9→min 17.9, near the wave-spawn ring 16!) — r0 now pinned
+  to the DESIGN radii (30/52), restoring idempotency (audit×2 → identical numbers); (2) the solar ARM reached
+  the generic branch before the Swivel cluster branch → rig fragmenting into a 0.4 u pole box.
+- **Validation (all passed)**: static bodies 249→323 (+74 = exactly the new adds), 10/10 solidity samples
+  (both slots + base), open room ground free (no over-collision), ring closure 32/32/region, server==client
+  parity 323, enemy smoke in the dense room (embedded-in-crater enemy depenetrated + re-engaged across ~12 u;
+  4 others converged through ~40 obstacles), 466/466 EditMode, console clean.
+
 ## Next-session intent

 Phase 1.5 continues: lighting/atmosphere pass → art-look decision gate (pixel filter ON/OFF side-by-sides).
-Operator: eyeball the refit walls + cover rocks + new prop colliders in a real lap (fidelity is numeric-verified,
-feel is not), plus the still-pending B5 split-panels visual smoke.
