Each daemon writes to <data-dir>/messages.db on startup. Messages received
or sent are stored immediately; duplicate mids (INSERT OR IGNORE) are safe
to call multiple times. Peer aliases are upserted on peer_connected and
again after hello verification when the real nick is known.
Schema
- messages(mid UNIQUE, room, from_peer, body, sent_at) — mid is the YAW/2
dedup key added in the proto migration; index on (room, sent_at) for
efficient per-room queries.
- peers(peer_id PK, alias, last_seen) — cache of every peer ever seen,
used to resolve hex ids to names when peers are offline.
Wiring
- store.Open called in cmd/daemon/main.go, passed to mesh.New.
- mesh.Mesh holds *store.Store (nil-safe; persistence is optional).
- mesh.SaveMessage called in dispatchPeerMessage (incoming) and ipc
CmdSendMessage (outgoing) so the local node's own messages are stored.
- mesh.UpdatePeerAlias called after hello verification updates the alias
with the verified nick rather than the placeholder short-id.
Messages only accumulate from join time forward — no history replay to
late-joining peers; each node's view starts from when it connected.
test-network.sh: added SQLite verification block that queries each node's
DB after the test and prints message + peer counts.

test-network.sh: shell script that starts anchor + alice + bob + charlie,
joins them to a named network, exchanges five messages, then has charlie
leave — verifying the full join/chat/leave cycle with coloured per-peer output.
ipc: two fixes exposed by the test script:
- Network join context was per-IPC-client, so the join was immediately
cancelled when the nc connection closed. Lifted join/leave state to the
Run() level (shared across all clients, protected by a mutex) so the
network stays connected independent of which client issued the command.
- Event-pusher goroutine could panic with "send on closed channel" when
the command loop closed writeCh while the pusher was mid-select. Added
defer recover() to both the pusher goroutine and the send helper, and
removed the default arm so the select blocks cleanly on done.
