Telemetry report schema

The exact body of the anonymous Telemetry report an Instance sends once a day. It carries no name, domain, address, host, error text, licence key or exact number. Counts are orders of magnitude, never exact figures. The schema is the contract: every report an Instance builds is checked against it.

The report operation and its schema are generated from the specification. The raw document is openapi/telemetry.openapi.json in the repository.
