KB: #175 paperwork -- drift-audit row 12 gains the static-world addendum (solid-tree sweep landed, 345 struct-class bench bursts, owner dispatch, the [T3 minor] fuze-vs-world same-frame ordering note); env-gate table gains BT_WORLDHIT + the BT_DESIGNATE HUD-ring clarification. Tracker #175 comment 1793.

- **#175 addendum (2026-08-13, 7b12053): the STATIC-WORLD half landed too.**
The flight step now also rays the static collision solid tree
(`WorldStructurePick` → `Mover::FindStaticSolidHitBy`) beside the visual
heightfield march, earliest hit wins — rounds burst on hills/structures
instead of tunneling (user-observed on grass: an LRM duel through a
mound; ALL 345 bench WORLD-bursts were struct-class — the mound was
solid-tree geometry the heightfield test was blind to). Struck solid's
owner takes the binary's zone=-1 direct dispatch (@004be078); salvo-lead
world bursts splash (near-miss vs cover). [T3 minor, pre-existing]:
world hits are tested before the same frame's fuze/bystander contact
rather than in one unified earliest-t arbitration — mixed ordering only
matters when a round crosses cover AND reaches its fuze point within a
single ~10-16u frame step. BT_WORLDHIT=0 = rollback lever.
