YAW/2 peer wire protocol is unchanged. Changes are local only.
internal/crypto:
- DeriveForNetwork(master, networkHash) — HKDF-SHA256 from master seed + network hash;
same master + same network always produces the same Ed25519 keypair (stable peer ID)
internal/proto:
- NetworkInfo type (network_id, network_name, local_peer)
- NetworkID field on IpcMessage (optional; commands default to first network when absent)
- Networks []NetworkInfo on state_snapshot (additive alongside existing local_peer)
- EvtNetworkJoined / EvtNetworkLeft events
internal/netmgr (new):
- Manager holds N independent Network contexts (derived identity, mesh, store, anchor)
- Join(name) creates context, derives identity, opens per-network DB, starts anchor client
- Leave(id) / LeaveAll() cancel contexts and close stores
- Resolve(netID) returns named network, or Default() when netID is empty (backward compat)
- Fan-out: Manager.Subscribe() receives tagged events from all networks
- Network IDs are the first 8 hex chars of SHA-256("yaw2-net:"+name) — stable and short
internal/ipc:
- Run(mgr, port) replaces Run(m *mesh.Mesh, port, anchorURL, joinFn)
- Commands without network_id route to mgr.Default() (backward compat)
- state_snapshot includes Networks array; local_peer/connected_peers still populated from first network
- generate_invite, get_file_list, send_message all respect network_id routing
cmd/daemon:
- Creates netmgr.Manager instead of mesh.Mesh directly
- --join and --share-dir pass through Config
- Auto-join via mgr.Join() before IPC starts
test-network.sh:
- Fix peer_name bash bug: $() with && inside triggers set -e; use if/elif/else instead

- proto: FileEntry, FileListResp types; MsgFileListReq/Resp msg types;
CmdGetFileList + EvtFileList IPC types; Files field on IpcMessage
- mesh: ShareDir field + ScanShareDir(); on DataChannel open, auto-send
MsgFileListReq to new peer; handle MsgFileListReq (scan + reply) and
MsgFileListResp (emit EvtFileList to IPC subscribers)
- ipc: get_file_list command — own list returned immediately; remote peer
list requested via DataChannel (response arrives as EvtFileList event)
- daemon: -share-dir flag wired to mesh.ShareDir
- test scripts: pass -share-dir /home/frejoh/Downloads/{alice,bob,charlie};
test-network.sh verifies each peer's own file list via get_file_list
- FUTURE.md: document per-network share directories and multi-network design

- TUI: replace per-call bufio.Scanner with a goroutine+channel reader
(lineReader) so a single scanner lives for the connection lifetime;
previous pattern silently dropped messages due to scanner read-ahead
- test-tui.sh / test-network.sh: add `return 0` to wait_port — when the
port opens and the while condition becomes false, bash returned the
condition's exit code (1) to the caller, tripping set -e immediately
- .gitignore: use /tui (root-only) instead of tui to avoid ignoring cmd/tui/

ipc: CmdSendMessage now routes to the named recipient only (m.SendTo) when
the "to" field is set, rather than broadcasting to all peers. Group messages
continue to use Broadcast. This is the correct privacy behaviour for DMs.
test-network.sh:
- Resolve each peer's hex id from get_state before joining the network,
using a retry loop with timeout to handle slow daemon startup.
- Added a DM section: alice→bob, bob→alice, charlie→alice, alice→charlie.
DMs use the "to" + "room":"dm:<peer_id>" convention.
- Fixed jq -cn (compact) instead of jq -n (pretty) so the IPC newline-
delimited protocol receives a single JSON line per command.
- pretty() now renders DMs as 📨 DM <from→to> rather than 💬 #room.
- Persistence check now breaks down totals by group vs DM message count.

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.
