The replaced radar sends only the empty 5/6 templates, a permanent zero-object world; the camera reads it as a dead radar and stops deciding auto high beams. Cycle an 8 s stock capture (2022 CX-5 city drive) per slot through create_radar_frames, byte-exact with the counter stamped per send, and pad each slot's empty tail to the stock duty cycle measured on the night drive where stock HBC was captured working (slots 5/6 at 59%/26% and 29%/12% across segments, played at 40%/20%; unequal 20 s/40 s periods). The captured frames stay pinned as the only occupied 5/6 patterns the Mazda tx hook accepts. Validated: 544 Mazda car tests + 278 safety tests; golden fixture regenerated for the deliberate 5/6 duty change.
The 0x362 template carried captured c7 8c bytes, a frozen non-empty track value stock never sends idle: every stock capture shows the same empty encoding as 0x361 (c0 00). The takeover parked a phantom object in slot 2 around the clock. Suspected cause of the green HBC telltale never arming under the takeover, device check pending: four captures show no other bus-content difference between green-on and green-dead worlds, and the beam gate reads only slots 5/6, matching blue working while green stayed dead. Fix: 0x362 template fff7fefe1fc78c80 -> fff7fefe1fc00080; the tx hook's TRACK_2 branch collapses into the 0x361 pattern and the retired capture is now rejected. Validated: 544 Mazda car tests + 278 safety tests; golden fixture regenerated for the template change.
