OptionalclaimThe exact-claim identity a mid-dispatch state report must present.
effectKey cannot serve: a lease takeover keeps the same key, so a
superseded handler holding only the key could still write. The token is
minted fresh on every claim and takeover; commitEffectOps rejects a
report whose token no longer matches before writing anything. Absent
only on claims persisted before tokens existed — those never match, so
their dispatches simply cannot report mid-flight.
OptionalleaseWhen this claim's lease lapses. Past this instant the claimer is
presumed dead: a drain may take the claim over and sweepStaleClaims
may force-release it. Absent only on claims persisted before leases
existed — treated as already expired, so the exact entries leases
exist to recover (claimed-then-abandoned) stay recoverable.
There is deliberately no attempt counter here: the retry count is the
effectClaimReleased history rows for the entry's _key (plus the
live claim), and a field would drift from that trail across releases.
A claim on a pending effect — presence means a drainer has taken dispatch responsibility for the entry. Absence means the entry is available. There is intentionally no
statusenum; presence ofclaimis the sole marker.Wire format includes
