Goal

Receive, validate and publish FC telemetry transported by VTX over the dedicated robust WFB stream from piotr/openipc-builder#4.

Scope

versioned parser with sequence/timestamp and stale detection;
immutable FlightTelemetry snapshot for issue #3 OSD state;
battery, GPS, arm/flight mode and attitude fields only when supplied/valid;
explicit source indicator: ELRS, WFB, or STALE/UNKNOWN where relevant;
log recording suitable for post-flight correlation.

Source precedence

Ground Station OSD uses WFB-carried FC telemetry as its independent live source. Do not copy handset/EdgeTX telemetry or infer battery/GPS from RC channels. Conflicting/stale values are labelled rather than silently merged.

Constraints

no dependency on video window/decoder;
no policy decision in parser;
malformed packets never clear the last valid snapshot until normal stale timeout;
telemetry rendering may lag video and must never block it.

Acceptance

OSD continues to show fresh battery/GPS/arm state when ELRS handset telemetry is intentionally unavailable but WFB telemetry stream remains received.
