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

- internal/invite: Encode/Decode waste:<base64json{anchor,network}>
- proto: CmdGenerateInvite + EvtInviteGenerated + InviteString field
- ipc: track active network name; handle generate_invite (returns invite
string when joined to a network, errors if not joined or no anchor)
- daemon: --join <invite> flag — decodes anchor URL + network name,
sets anchor and auto-joins on startup
- tui: --join <invite> flag — extracts network name, skips -network
requirement; ctrl+i generates invite and shows it full-screen;
Esc dismisses the invite overlay
- FUTURE.md: document multi-network derived-identity design

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.
