After hello verification, the connecting peer sends history_request to
the first peer it meets (one per room, no fan-out). The responder queries
SQLite and replies with a history_chunk. Received history is stored via
INSERT OR IGNORE (mid dedup) and emitted as history_loaded IPC events.
- proto: MsgHistoryRequest/Chunk types, HistoryEntry, EvtHistoryLoaded,
ComputeMsgID (sha256 content-addressed ID), MsgID field on ChatMessage
- store: ALTER TABLE ADD COLUMN msg_id + unique index migration (idempotent);
RecentMessagesSince query (msg_id IS NOT NULL filter); msg_id persisted on save
- mesh: RequestHistoryFrom, HandleHistoryRequest, HandleHistoryChunk methods;
historyRequested/historyFirstPeer state to ensure single-peer requests
- peer: dispatch history_request/history_chunk; RequestHistoryFrom after hello;
stamp MsgID on incoming chat messages
- ipc: stamp MsgID on outgoing group chat messages
- EXTENSIONS.md: EXT-007 documented

Daemon:
- Per-network download directories (-download-dir flag, set_download_dir IPC)
- File transfer resume after disconnection: .tmp.meta sidecars survive
interruption; resume_offset in file-accept lets sender seek and continue
- set_download_dir IPC command; download_dir reported in state_snapshot
Protocol:
- PeerMessage.ResumeOffset (EXT-006) for file transfer resume
- IpcMessage.ShareNetworks json tag changed from "networks" to "network_ids"
to fix duplicate json tag collision with Networks []NetworkInfo
Desktop app (cmd/app):
- Wails v2 shell embedding daemon logic directly (no subprocess)
- System tray on Linux/Windows via getlantern/systray; macOS hides to Dock
- OS notifications for message_received and file_complete via Wails events
- notray build tag for headless/CI builds without GTK tray headers
- build-app.sh: builds web frontend, copies dist, runs wails build
Web / PWA:
- manifest.json + Apple touch icon meta tags for mobile "Add to Home Screen"
- PNG icons (192px, 512px, 180px) generated from SVG
- Wails EventsOn("notify") hook in App.tsx for native OS notifications
CI:
- .gitea/workflows/build.yml: server binaries cross-compiled for 5 platforms,
desktop app for Linux amd64, release artifacts published on v* tags
Docs:
- README: download dir, file transfer resume, desktop app, PWA, CI sections
- EXTENSIONS.md: EXT-004 daemon mode marked shipped; EXT-006 resume added
- FUTURE.md: roadmap updated

- Signed invites: waste: URI gains inviter+sig fields (Ed25519); hello
carries the invite so receiving peers can verify against known keys
- RequireInvite per-network flag: rejects peers without valid signed invite
- Hash-based hang links: #waste:base64 fragment pre-fills join form without
server-side leakage of network name
- Multi-share: shares.json (daemon) + waste_shares localStorage (browser);
IPC add_share/remove_share/list_shares commands
- EXTENSIONS.md: addendum documenting all waste-go protocol deviations from
YAW/2; all extensions are additive and backward compatible
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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.

When a peer's hello is verified, send a gossip burst of currently
connected peers so the new peer can discover and connect to nodes it
hasn't met yet — without relying on the anchor for a full peer-join
notification for each one.
- mesh: add PendingConnect chan for gossip-discovered peer IDs
- peer: send gossip burst after hello; push unknown peers from incoming
gossip onto PendingConnect (skip self + already-connected)
- anchor: drain PendingConnect per runOnce, initiate startOffer for
unknown peers using the same lexicographic tiebreak as anchor join;
drain goroutine is scoped to the runOnce lifetime to avoid using stale
sessions after a reconnect

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).

- 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

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.
