Night-watch caught the instability in the act at 7min uptime: E H_SDIO_DRV: sdio_write_task: Failed to send data: 258 (timeout) E H_SDIO_DRV: Unrecoverable host sdio state -> SW_CPU_RESET i.e. esp-hosted-mcu#167. Known mitigation: 1-bit SDIO bus (#148), still ~80x voice bandwidth. Also: recovery reboots no longer ring the gong (esp_reset_reason gate) - a butler doesn't bong at 3am.
