nRF crash evidence

crash_ram_20260912.bin — 262 KB RAM snapshot from Board V1 (watch role) carrying the SoftDevice Controller assert 23, 587, taken 2026-09-12 18:35. Copied here by /parselogs on 2026-09-20 because the only copy was inside ImpulseFirmware/nrf_firmware/build-watch-cs-buzz/, an untracked build directory that a single ./build.sh watch -p always deletes. The original is still there; this is a second copy, not a move.

It is the evidence for the Nordic DevZone case that has not yet been opened (Todos.md). Context — NCS v3.4.0, nRF54LM20A initiator-only, main mode 2 / sub-mode 1, fired twice within minutes of channel sounding starting, the first time halting the CPU with the motor latched on — is in docs/agent-notes.md, 2026-09-12, along with the DRGN-29669 question. 23, 587 is undocumented in NCS v3.4.0.
