# mesh-delivery

The `mesh-delivery` module of the mesh catalogue: claims the seat `mesh-delivery`.

## Files it does not know

Each directory or archive this module declares says how it treats a file it did not write (ADR 0422, ADR 0416).

- `${dir:state}`: everything in it is the program's; the mesh moves nothing out (ADR 0422 §2).

## A backup that failed before the send

The controller backs up the data of the modules a delivery moves before it asks or sends anything (ADR 0404). When its
walk's record, in `plan-moved`, names a backup that failed or stayed silent and nothing of the plan was sent, the
delivery goes from delivering to held (the observed row `backup failed`); the held reason names the machine, the
module and the backup's words, and the pull request's comment shows it. The hold does not lift by itself. `release`
of such a delivery asks the controller (`delivery-backups-again`) to take the backups again and the delivery goes on
delivering; a record from before the controller cleared the failure does not hold it again. A held delivery already
ends as covered or delivered when a later merge covers it.
