ci.run (one row per finished job, exactly once via a high-water mark;
branch_kind default|pr|other so the dashboard can show "main is red") and
service.health (interval counts: finished/failed/cancelled, waiting,
running, runners online, oldest wait). Shapes declared with Windy
Telemetry 40; sends nothing until WINDYGIT_TELEMETRY_TOKEN exists.
State is only advanced after a 2xx, so a failed post retries.
