An event was a tree of values encoded into a new string, a dropped line was never given back, and every batch and save joined the queue into another. Now: telemetry_props / telemetry_str / _int / _bool write the properties as JSON into a buffer the state keeps; the line is written beside it, its time worked out from the clock's seconds (TelemetryWorld.clock_s, was stamp); its bytes go into one ring (ring_bytes, at most queue_max lines), the oldest overwritten past either; a batch and the file are written into a third kept buffer and go as bytes (TelemetryTransport.send takes the bytes and their length; Http.body_bytes, Fs.write_bytes). The facts are pooled. tests/ring_test: ten thousand events past the cap in lines and in bytes, 0 bytes of heap; the line exact JSON, escaped, 2000-02-29 right; the batch puts the id in; the file round-trips.
