Only 24 of 144 direct messages and posts in the history were ever marked
delivered. Three faults, each fixed:
- The wait was the radio's own estimate times 1.2: about 5.7 s for a
flood, while a flooded round trip from a few hops out takes ten (a
room's answer from five hops landed at 10.1 s on hardware). It is now
the login's patience, the estimate stretched a quarter plus a round
trip sized to the route, about 15 s for a flood.
- An ack that landed after the wait was dropped. The radio pushes one
whenever it arrives, for any of its last eight sends, but nothing was
listening, so a delivered message stayed failed for good. The history
shows ACK and PATH packets heard seconds after messages recorded as
failed. The send now returns a Delivery carrying the ack code, and the
chat service keeps the last sixteen messages still waiting. A late ack
flips one to delivered, in history and in the message the chat screen
holds, and every code a retried message went out under counts.
- The Courier trusted the failure and sent the message again: a
duplicate for the recipient whenever the ack was only late. A late ack
now marks the entry delivered.
The ack listener is also armed before the send rather than after it,
so a neighbour's ack quicker than the send's own return is not missed.
The debug log names how a message went out and the radio's own
round-trip time.
