Optional ReadonlycapturePresent only when explicit capture persistence was requested. Never inferred from an ordinary flush.
ReadonlyentriesEntries handed to the adapter (each opened, commit, note, closed call).
ReadonlyfailedLosses — a method that threw or rejected, an entry the log refused to send, a meta the log could not copy
(that entry was still stored, without it), and failed or timed-out flushes. A rejection that settles after the
run finished is counted when it settles.
Optional ReadonlylastThe last loss's error, as text. Absent while nothing was lost.
getSnapshot().sink— what the run handed its sink, and what the sink did not take (10.1, P6).
