Sending to a contact the firmware no longer holds came back as
`send failed: failed to send message to 'bob_caribou': {'error_code': 2,
'code_string': 'ERR_CODE_NOT_FOUND'}` — a wire constant in a status line, and
no hint of what to do about it.
It is reachable for a contact MeshTerm itself listed. The list a screen sees is
the union of the device's live table and the contacts MeshTerm remembers for
that device (core/contact_store), which exists so a RAM-only radio bridge still
shows the nodes you know. The store claims those stay messageable without
writing anything back — true for the bridge, false for a firmware companion,
which addresses a direct message by looking the recipient up in its *own* table
by a key prefix and refuses when nothing matches. So a contact the firmware has
dropped still lists, still opens a chat, and only the send finds out it is gone.
Now the rejection is its own class carrying the contact, and the chat offers the
one write that fixes it: "bob_caribou isn't in this device's contacts, so the
radio can't address it. Add it back and send?" — Cancel or Add & send, then the
same send runs again. Declining reports the refusal in words. The write is
offered rather than silent because it changes what the device stores, and a full
contact table refuses it, which is worth seeing. Retry (^R) takes the same path.
Adding a contact is new to the Device contract (the inverse of remove_contact,
ADD_UPDATE_CONTACT on the wire): the record carries the key, name, type and last
advertised position we already hold, with no learned route, so the first message
floods exactly as it would for a freshly-heard node. The name is clipped to the
32 *bytes* the firmware field holds, not 32 characters.
Every other rejection now reads as a sentence too — reject_reason maps the six
error codes to plain words, so a send, an admin command, or any _ok()'d command
says "the device's table is full" rather than printing its payload dict. The
simulator refuses a recipient it doesn't hold, exactly as hardware does, so the
whole offer is walkable under --mock.
