Tail a dataset's logs

Live tail, served on the live host obs-live.ezghcloud.com with the API host's credentials: newly accepted records as server-sent events, before they're searchable. Read it with fetch and a streamed body (not EventSource). Events: records (id: the newest accepted_at in the batch, in Unix milliseconds; data {"records":[LogRecord…],"keptRatio":r}); sampled (data {"keptRatio","matchedPerSecond","sentPerSecond"}) whenever the kept ratio changes; gap (data {"since","until","reason":"replayLimit"}) when a resume can't be replayed in full; end (data {"reason"}: maxDuration, revoked, datasetDeleting, slowConsumer, draining or unavailable); and a heartbeat comment every 15 seconds. A stream lasts at most 15 minutes. Resume with lastEventId, the last records event's id: records accepted since then (up to 5 minutes back) are replayed beside the live ones, may repeat or arrive out of order, and are de-duplicated by recordId. Above maxRate records per second the stream samples, the same records on every server. 429 too_many_requests: all of the organization's live tails are open. 503 unavailable: retry after Retry-After. Not idempotent: each request is a new stream.
