The BT-off custom slave (2.12.12) can't survive the C6's OTA rollback protection: it flashes, the C6 boots it, reverts to 2.12.11, host reflashes -> ~30s reboot loop, worse than the wedge. BLE-coex hypothesis is UNTESTABLE via OTA (custom slaves won't stick; needs direct C6 UART flash, out of scope tonight). Reverted to the self-healing 2.12.11 baseline: ~5-13min MTBF, 15s auto-recovery. That is the shippable overnight state. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

/* One-shot ESP32-C6 slave firmware update over the SDIO RPC channel.
|
|
*
|
|
* The factory C6 firmware's data path never carried a frame (control RPC
|
|
* works; all data traffic dies). This streams a slave image built from the
|
|
* exact same esp_hosted version as the host driver, using the RPC OTA
|
|
* primitives that ride the (working) control path — no network involved.
|
|
*
|
|
* Remove the c6_ota_start() call from app_main once the radio is proven.
