OTA (Parallax)

Over-the-air update schedule, download state, deployment.

RVMs

RVM	Protobuf hints	Legacy correlate
`ota.user_schedule.ota_config`	`r70/u`, `r70/i`	`otaInstallTime`, schedule
`ota.ota_state.vehicle_ota_state`		`otaStatus`, `otaCurrentStatus`, download/install progress
`ota.deployment.state`		`otaInstallReady`, version fields

Legacy query getOTAUpdateDetails — release notes (HTTP, not Parallax).

Install-now → PARALLAX_OTA_COMMAND + sendParallaxPayload.

Most OTA progress fields still appear on GetVehicleState and vehicleState WebSocket subscription.
