 Owner direction 2026-10-28: unified style over historical compatibility, inside `src`.
 No numerical change is intended. Stages after 5f69eba: 65339ab (one boundary/Jet record,
 host preparation helpers, pair accessors), c5a3cdb (`block_collide` families), 442979b
-(exchange metadata on the boundary record). Each was checked by parent/candidate
-config.h/PTX comparison and host/GPU equality runs; c5a3cdb changed the PTX of the two
-channel-root SRT modules only (omega load/clamp moved, outputs exact).
+(exchange metadata on the boundary record). All three received parent/candidate
+generated-config and host/GPU equality checks. Only the collision slice ran a new PTX
+matrix (a4fc46d, whose src is identical to c5a3cdb); 65339ab and 442979b reused prior
+PTX evidence after unchanged CUDA/compiler and generated-input checks. In the collision
+matrix, only the two channel-root SRT modules changed PTX (omega load/clamp moved);
+their parent/candidate outputs matched exactly in the exercised cases.
