This is the canonical technical reference for ItsGoin. It describes the vision, the architecture, and the current state of every subsystem — with full implementation detail. This document is versioned; each update records what changed.
v0.4.3 (2026-03-22): Lock contention overhaul — all conn_mgr lock holds during network I/O eliminated. PostFetch, TcpPunch, PullFromPeer, FetchEngagement, ResolveAddress, AnchorProbe, WormLookup, ContentSearch now use brief locks for data gathering only. Bi-stream handlers (BlobRequest, WormQuery, RelayIntroduce, PostFetchRequest, ManifestRefresh) fully lock-free for I/O. ConnectionActor hoists shared Arcs (storage, blob_store, endpoint) for lock-free access. ResolveAddress adds 5s per-query timeout (was unbounded). Worm cascade uses connection snapshots. Initial exchange failure now aborts mesh upgrade (was silently continuing). connect_to_peer/connect_to_anchor use 15s timeout. StoragePool — 8 concurrent SQLite connections in WAL mode replace single Mutex<Storage>. Reads run fully parallel; writes serialize only at SQLite level. Bottom nav bar for mobile/tablet (≤768px) with icon tabs. Text sizes: XS 75%, S 100%, M 125% (default), L 150%, XL 200%. Text size persisted to localStorage for instant restore.

Bottom nav bar for mobile/tablet (≤768px) with icon tabs. Text sizes: XS 75%, S 100%, M 125% (default), L 150%, XL 200%. Text size persisted to localStorage for instant restore. Fix: blocking_lock panic inside async runtime (prevented app startup). StoragePool reduced to 4 connections for Android compatibility.
v0.4.2 (2026-03-22): Welcome screen — startup shows “How’s it goin?” with staggered counters (connections, posts, messages, reacts, comments) while backend bootstraps. Status ticker — header ticker for new posts, messages, reactions, comments, connection changes. Notification improvements — Tauri plugin → Web Notification → notify-rust fallback chain, Linux native notifications. Responsive text scaling — Small/Normal/Large (100%/150%/200%), persisted via settings. Diagnostics popover — diagnostics moved from inline section to overlay, connections on-demand, timers removed. Share details lightbox with QR code. Connect string prefers external address (UPnP/public IPv6/observed). Stale N1 fix — disconnected social routes excluded from N1 share. Replication handler fix — actively fetches posts + blobs from requester after accepting replication. Hole punch fix — target-side registers publicly routable remote address for relay introduction. Replication semaphore (3 concurrent max). Peer labels show truncated node ID.
v0.4.1 (2026-03-21): Security hardening — reaction signatures (ed25519), comment signature verification on receipt, reaction removal authorization, BlobHeader author verification. Lock contention fixes — ManifestPush discovery (cm lock released during I/O), pull request handler (filter without lock), pull sender (split into brief locks), engagement checker (batch writes per chunk). Data cleanup — post deletion cleans downstream/upstream/seen tables.
v0.4.0 (2026-03-21): Protocol v4 — header-driven sync. ManifestPush as primary post notification. Slim PullSyncRequest (per-author timestamps, not full post ID list). Tiered engagement checks (5min/1hr/4hr/24hr by content age). Multi-upstream (3 max) with fallback chain. Auto-prefetch followed authors <90d. Self Last Encounter per-author tracking. Encrypted-but-not-for-us CDN caching. Serial engagement polling. ~90% bandwidth reduction for established nodes.
