Interface OutboxRecord

Idempotency key: explicit, derived from the inbound being handled, or random.

The inbound record (or job) whose handling produced this send.

Encoded OutboundContent (Buffers base64-encoded).

Encoded SendOptions (without idempotencyKey).

Provider attempts so far.

The provider's message ref, written by the same operation that sets sent.

Hash of the chat + encoded content the record was journaled with (before before('send') hooks). A replay whose derived key matches but whose content differs is a new send.

The key of the record that must be sent before this one: set on the later parts of a split text (<key>#2 follows <key>, <key>#3 follows <key>#2…). The sweeper never sends a record while that one is still to be sent, and dead-letters it when that one is dead. A key ending in #<n> chosen by the caller has no such link.

When the record reached a terminal state (sent, dead, unknown).
