Expand description

Verification state machine.

Each unknown key transitions through these states exactly once per offer lifecycle. See Section 8 of REPLICATION_DESIGN.md for the full state-transition diagram.

Variants§

§

OfferReceived

Offer received, not yet processed.

§

PendingVerify

Passed admission filter, awaiting quorum / paid-list verification.

§

QuorumVerified

Presence quorum passed (>= QuorumNeeded positives from QuorumTargets).

§

PaidListVerified

Paid-list authorisation succeeded (>= ConfirmNeeded confirmations or derived from replica majority).

§

QueuedForFetch

Queued for record fetch.

§

Fetching

Actively fetching from a verified source.

§

Stored

Successfully stored locally.

§

FetchRetryable

Fetch failed but retryable (alternate sources remain).

§

FetchAbandoned

Fetch permanently abandoned (terminal failure or no alternate sources).

§

QuorumFailed

Quorum failed definitively (both paid-list and presence impossible this round).

§

QuorumInconclusive

Quorum inconclusive (timeout with neither success nor fail-fast).

§

QuorumAbandoned

Terminal: quorum abandoned, key forgotten.

§

Idle

Terminal: key returned to idle (forgotten, requires new offer to re-enter).
