LedgerEntry

subscription of service parks aggregate, as its ledger holds it now (FailureLedger's entry with the retry spec it is retried by); the entry's command topic is context's, the context of the subscription.

• fromVersion and fromPosition: where the aggregate is parked; reason and failedAt (epoch milliseconds): why and when it last failed, which also tells one parking of the aggregate from the next.

• retries made so far, the last started at retryAt; retrySpec, the spec it is retried by; nextRetryAt the next automatic retry, null when there is none.

• recoverable: unknown, recoverable or unrecoverable, what an operator marked it; request: retry or skip while an operator's request waits for the owner of its partition, else null.

• status: scheduled (retried automatically), exhausted (its retries spent) or unrecoverable.

Each is the wire name (me.ahoo.wow.api.wire.WireNames) of the ledger's value, which the ledger stores as it always has.

• recordedAt: when the service published it (epoch milliseconds).

Fields may be added: the runtime's ledger publisher builds it, and a reader reads it from its JSON; the constructor is internal to Wow.
