Arkfile reviews the proposed entropy fix in Coldcard firmware pull request 692, confirms rng_get now reaches the board TRNG, and reports that the new rng_get_or_fault helper has no recovery path for STM32 RNG error flags so a single fault latches the peripheral into an unrecoverable timeout. Verified against the captured post text and linked GitHub pull request.
