# `ExWapp.Session.Worker.SendRecovery`
[🔗](https://github.com/elchemista/ex_wapp/blob/v0.1.5/lib/ex_wapp/session/worker/send_recovery.ex#L1)

What the session does when a send does not land.

Three recoveries live here, in the order the server pushes the session through
them:

- **resend** — the payload of every outgoing message is remembered briefly so
  it can be sent again without asking the caller to rebuild it
- **repair** — a rejected send usually means the peer's Signal session is
  stale, so it is dropped and renegotiated before the resend goes out
- **placeholder** — when a message arrives that this device cannot decrypt at
  all, the primary device is asked to send it again

Retries run in worker processes started from here; like everything else called
by the session, this code runs inside the session process, so those workers are
started by it and report back to its mailbox.

A rejection is only reported to the caller once no recovery is left: reporting
early would surface an error for a message that is about to be resent
successfully.
