### Deliverables
**Phase 1: LatticeServer Refactor**
**Phase 1: LatticeServer Refactor** ✓
- [x] `LatticeServer` struct in `lattice-net` wrapping `Arc<Node>` + `Endpoint`
- [x] Move `join_mesh`, `sync_with_peer`, `sync_all` to `LatticeServer` methods
- [x] Encapsulate `spawn_accept_loop` inside `LatticeServer`
- [x] Encapsulate accept loop inside `LatticeServer` (via Router + ProtocolHandler)
- [x] CLI uses `LatticeServer` instead of raw `Node` + `Endpoint`
- [ ] Route sync command through `LatticeServer` (not raw functions)
- [ ] Integration test: invite → join → sync end-to-end
- [ ] Periodic background sync with known peers
- [ ] Track last sync time per peer
**Phase 2: Gossip Protocol**
- [ ] Proto: `GossipAnnounce` message with author + latest seq + HLC
- [ ] `LatticeServer::spawn_gossip_loop` for periodic announcements
- [ ] On receiving announce: detect missing entries, trigger sync
- [ ] Track last-seen per peer for staleness detection
**Phase 2: Gossip Protocol** ✓ (iroh-gossip)
- [x] Router handles both `lattice-sync/1` and `/iroh-gossip/1` ALPNs
- [x] `NodeEvent::RootStoreActivated` emitted when root store opens
- [x] Auto-join gossip topic on root store activation
- [x] Broadcast local entries to gossip topic on commit
- [x] Receive gossip entries and apply to store
- [x] Topic ID via `blake3::hash("lattice/{store_id}")`
- [ ] Gossip bootstrap peers from `/peers/` (needs Prefix Watch)
**Next: Prefix Watch (reactive store updates)**
- [ ] `store.watch_prefix(prefix) -> Receiver<WatchEvent>`
- [ ] `WatchEvent::Put { key, value }` / `WatchEvent::Delete { key }`
- [ ] StoreActor tracks watchers per prefix, emits on matching put/delete
- [ ] LatticeServer uses `/peers/` watch to update gossip bootstrap peers dynamically
- [ ] Enables reactive patterns: config changes, presence, app-level subscriptions
---
## Technical Debt
**Logging**
- [ ] Replace `println!`/`eprintln!` with `tracing` crate (`tracing::info!`, `tracing::error!`)
- Standard in Rust async ecosystem, used by Iroh internally
**Lifecycle Management (Zombie Tasks)**
- [ ] Spawned infinite loops (`spawn_node_event_listener`, `spawn_entry_forward_loop`, gossip receive loop) keep running if `LatticeServer` is dropped
- [ ] Use `tokio_util::sync::CancellationToken` or keep `JoinHandle`s for graceful shutdown
**Error Handling**
- [ ] Replace `Result<..., String>` with `anyhow::Result` or define `LatticeNetError` enum
- String errors make it hard to handle specific failure cases
---
## Future
- offline nodes should not delay sync
- sync command should transitive sync all peers
- Gossip:
- gossip new entries to peers
- backfill missing entries from peers (how do peers notice missing entries?)
