Daemon side:
- internal/shares: new package reads/writes shares.json next to identity
- proto: add ShareEntry type, add_share/remove_share/list_shares IPC commands,
shares_list event, path field on FileEntry
- netmgr: load shares.json on startup; ScanAllShares combines legacy ShareDir
with shares.json entries (recursive walk with relative paths)
- mesh: ScanFiles callback lets manager inject multi-share scanning without
mesh knowing about shares.json
- ipc: handle add_share, remove_share, list_shares commands
Browser side:
- ShareManager component replaces FolderPicker: shows list of named shares
with remove/re-pick buttons; persists share records to waste_shares in
localStorage (name, global flag, networkId)
- FolderPicker retained for internal use; Sidebar now uses ShareManager

Hooks pc.OnConnectionStateChange in WireDataChannel to emit peer_status
events. On connected, calls pc.GetStats() to find the nominated candidate
pair and report candidateType (host/srflx/relay) and remote address.

Protocol:
- invite.go: include full 64-char `net` hash in waste: invite blob
(matches yaw2's `net` field — any client parsing the base64 JSON can
join without knowing the plaintext name). Expose NetHash() helper.
- netmgr: add JoinByHash() — join via full 64-char hex hash alone,
storing the short ID as display name. Enables joining yaw2 networks
from a URL that only carries the hash.
- anchor: expose RunByHash() so netmgr can pass a pre-computed hash
directly without a name→hash roundtrip.
- ipc/proto: add network_hash field to join_network — routes to
JoinByHash when present and network_name is absent.
Web UI:
- Parse ?net=<64hex> (yaw2 URL param) and ?a=<anchor> in addition to
existing ?n= / ?invite= params. Hash-only joins send network_hash.
- Sidebar shows yaw: contact card (yaw:<masterID>?n=<alias>) using the
master identity — compatible with yaw2 contact card format. Click to
copy to clipboard.

Messaging:
- Append \n to WS IPC sends so bufio.Scanner fires (messages from web
were silently dropped — the line scanner never saw a newline)
- Handle session_ready in web store to update peer aliases after hello
Alias resolution:
- Seed AddPeer alias from SQLite cache so returning peers resolve
immediately, before hello exchange completes
- Remove stale SavePeer call from AddPeer (was writing placeholder IDs)
- Add PeerAlias() point-lookup to store
Onboarding redesign:
- Three-state UI: disconnected (daemon instructions), connecting,
connected-no-network (join form)
- Read ?n= / ?network= / ?anchor= / ?invite=waste:... URL params to
pre-fill the join form for invite links
- Show daemon alias + peer ID before any network is joined
(master_alias + master_id now included in state_snapshot)
- Identity backup: export (passphrase-protected yaw-key-backup-1 JSON,
download button) and restore (paste + passphrase verify)

Each network now carries its own share dir, set at join_network time via
optional share_dir field or updated live with set_share_dir. The global
-share-dir daemon flag becomes a fallback default.
- proto: add ShareDir/DownloadDir to NetworkInfo and IpcMessage
- netmgr: Join accepts shareDir override; SetShareDir updates live
- ipc: wire join_network share_dir and set_share_dir command
- daemon: remove -share-dir from auto-join path (pass "" for default)
- test-network.sh: per-network join with share_dir; isolation verification
section confirms alice/friends and alice/work share dirs are independent
- test-tui.sh: join_network with share_dir; peer IDs resolved after join
All tests pass: YAW/2.1 FS, share isolation, file transfer, persistence.

Upgrades the signaling layer from static X25519 (2.0) to per-session
ephemeral X25519 (2.1). Recorded signaling traffic cannot be decrypted
even if long-term Ed25519 keys later leak, because esk is zeroed on
session close.
Protocol:
- Each peer generates a fresh X25519 keypair (esk/epk) per session.
- Peers exchange signed `ekey` messages sealed under static keys before
the offer/answer. Offer/answer/candidate payloads are then sealed with
ephemeral keys (crypto_box(·, peer_epk, my_esk)).
- ekey sig binds both peer IDs and the epk to prevent replay to third parties.
- Offerer waits up to 2 s for the peer's ekey; if none arrives it falls back
to YAW/2.0 static-key sealing and logs "2.0 fallback offer".
- 2.0 peers silently ignore the unknown `ekey` kind — full interop preserved.
Implementation:
- crypto.go: add EphemeralKey.PublicRaw/PrivateRaw/Wipe helpers.
- proto.go: add SigEkey kind; EPK/V/EkeySig fields on SignalingPayload.
- anchor/client.go: replace flat pcs map with peerSession struct tracking
ephemeral keys, peerEPK, and fs flag; openBoxAuto tries ephemeral then
static; sealAndSend chooses seal based on session state.
- test-network.sh: pipe daemon stderr through tee to daemon.log; add
YAW/2.1 FS verification section.
- test-tui.sh: same daemon.log capture.
- README.md: document 2.1 forward secrecy, file transfer IPC, updated roadmap.

File chunks travel over a per-transfer "f:<xid>" WebRTC DataChannel —
direct DTLS-encrypted P2P, the anchor never sees file data. Once the
initial handshake is done the anchor can disappear and transfers continue.
Key design choices:
- Receiver sends "ok" on the file DC before sender streams, eliminating
a race where tiny files could be fully sent/closed before the receiver's
OnMessage handler is registered (open-race §6 analogue for data DCs).
- Auto-accept: receiver accepts every incoming offer immediately.
- Download dir: per-network at <data-dir>/downloads-<netid>/.
- Backpressure: bufferedAmountLowThreshold to avoid overwhelming the DC.
- SHA-256 verified on receive; mismatches emit EvtError and discard temp file.
- IPC: send_file {peer_id, path} → offers the named file from share dir.
- EvtFileComplete {transfer_id, path} emitted on success.
IPC command: {"type":"send_file","peer_id":"<hex>","path":"<filename>"}

Five interop issues fixed against PROTOCOL.md:
- Join signature now covers nonce_raw || net_ascii (64-char UTF-8 hex
string) as specified in §5.1, not net_raw_bytes. Both anchor server
and client updated to match.
- Chat wire fields renamed to spec names: text/ts (Unix ms int64)
replacing body/sent_at (ISO timestamp). Flat layout on PeerMessage
matches §8 exactly; store and TUI updated accordingly.
- Direct messages now use the spec "pm" type (flat {type,mid,text,ts})
instead of chat+to. Receiver reconstructs a ChatMessage with
dm:<short-id> room for IPC/storage. §8 compliant.
- File transfer message types changed to spec hyphenated names:
file-offer, file-accept, file-cancel, file-done with spec field
names (name/size not filename/size_bytes). §9 compliant.
- DataChannel open-race (§14 gotcha #3) fixed with sync.Once: doOpen
fires on OnOpen callback or immediately if the channel is already
open when WireDataChannel is called (answerer race).
Also fixes two bugs found during testing:
- mid was missing from outgoing wire messages, causing all received
messages to arrive with mid="" and collide on the UNIQUE DB
constraint. mid is now included on all sent chat/pm messages; a
random mid is generated for any received message that omits it.
- Test scripts hardened: kill -9 + active lsof polling replaces blind
sleep for port cleanup; join_network sent before peer_field queries
(local_peer is now network-scoped and nil until joined).

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

- 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
