Sticky header with tabs as one block on desktop. Fixed header + bottom nav on
mobile. Full-width dark header (#0a0a1a) edge-to-edge with 15px fade gradient.
Tab icons on desktop (inline) and mobile (stacked). Safe area inset support for
phone notches. Lightboxes close on tab switch.
Profiles lightbox (name, bio, visibility, circle profiles) and redundancy
lightbox moved from settings to My Posts. Sync All and Stored Anchors moved
into Network Diagnostics popover. Network indicator click opens diagnostics.
Settings streamlined — removed profile editor, diagnostics button, sync,
redundancy, anchor management.
Keepalive fix: tokio::time::sleep in select! never fired; switched to interval.
Auto-reconnect on unexpected disconnect with 3s delay. notify_growth on
disconnect. Tab badge fix preserving icon spans. Feed re-render skip during
media playback.

Eliminate all conn_mgr lock holds during network I/O across 14 actor commands
and bi-stream handlers. PostFetch, TcpPunch, PullFromPeer, FetchEngagement,
ResolveAddress, AnchorProbe use brief locks for data gathering only. WormLookup,
ContentSearch, WormQuery use connection snapshots for lock-free cascade fan-out.
RelayIntroduce extracts forwarding data under brief lock, does I/O outside.
BlobRequest, PostFetchRequest, ManifestRefresh use Arc clones instead of conn_mgr
lock. ConnectionActor hoists shared Arcs (storage, blob_store, endpoint) for
lock-free access. ResolveAddress adds 5s per-query timeout (was unbounded).
Initial exchange failure now aborts mesh upgrade (was silently continuing with
broken connection). connect_to_peer/connect_to_anchor use consistent 15s timeout.
Rebalance connects outside the lock via pending_connects pattern.
StoragePool: 8 concurrent SQLite connections in WAL mode replace single
Mutex<Storage>. Reads run fully parallel; writes serialize at SQLite level only.
PRAGMA busy_timeout=5000 for graceful write contention.
Mobile bottom nav bar (<=768px) with icon tabs. Text sizes: XS/S/M/L/XL
(75%/100%/125%/150%/200%), default M. localStorage persistence for instant
restore. Toast repositioned above mobile nav.

Welcome screen with staggered counters while backend bootstraps. Header status
ticker for new posts/messages/reactions/comments/connection changes. Notification
fallback chain (Tauri plugin → Web API → notify-rust). Responsive text scaling
(Small/Normal/Large, persisted). Diagnostics moved to popover with on-demand
connections. Share details lightbox with QR code. Connect string prefers external
address. Stale N1 fix (disconnected routes excluded). Replication handler actively
fetches posts+blobs from requester. Hole punch registers remote address for relay.
Replication semaphore (3 concurrent). Peer labels show truncated node ID.

Security:
- Reaction signatures: ed25519 sign/verify (sign_reaction, verify_reaction_signature)
Backward-compatible — unsigned reactions from old nodes still accepted
- Comment signature verification: verify_comment_signature now called on receipt
- Reaction removal authorization: only reactor or post author can remove
- BlobHeader author verification: lookup actual author from storage, don't trust payload
Lock contention (4 fixes):
- ManifestPush discovery: cm lock released before PostFetch I/O
- Pull request handler: load under lock, filter without lock, brief re-lock for is_deleted
- Pull sender: split into two brief locks (store posts, then batch upstream+sync)
- Engagement checker: batch all chunk results, single lock for writes
Data cleanup:
- Post deletion cleans post_downstream, post_upstream, seen_engagement tables
- Added TODO-hardening.md documenting remaining DOS/security/lock/data issues

Encrypted slots in BlobHeader:
- Private posts get noise-prefilled receipt slots (64B, 1 per participant)
and comment slots (256B, ceil(participants/3), expandable)
- Slot key derived from post CEK via BLAKE3 — only participants can read
- CDN relays propagate opaque encrypted bytes without decryption
- 3 new BlobHeaderDiffOps: WriteReceiptSlot, WriteCommentSlot, AddCommentSlots
Receipt system:
- States: empty(0), delivered(1), seen(2), reacted(3)
- Slot index = position in sorted participant NodeId list
- Author can pre-feed emoji reaction at creation time
- 6 new crypto tests for slot encrypt/decrypt/derivation
Node methods:
- write_receipt_slot, write_comment_slot with upstream+downstream propagation
- read_receipt_slots, read_comment_slots with CEK-based decryption
- get_post_cek_and_participants helper for both Encrypted and GroupEncrypted
IPC: write_message_receipt, write_message_comment, get_message_receipts,
get_message_comments
Frontend:
- DM chat bubbles show delivery indicators (check → double → blue → emoji)
- Opening conversation auto-marks incoming messages as seen
- React button on messages with emoji prompt

Comment edit & delete:
- EditComment/DeleteComment BlobHeaderDiffOps with upstream+downstream propagation
- Trust-based: comment author can edit/delete, post author can delete
- Storage: edit_comment(), delete_comment() methods
- Frontend: inline edit (Enter/Escape), delete with confirm
Native notifications:
- tauri-plugin-notification for system notifications on all platforms
- Triggers for messages, new posts, reactions, and comments
- notif_reacts setting added, button-group toggles replace dropdowns
- _notifReady flag prevents startup spam
Protocol hardening:
- BlobHeaderDiffOp::Unknown variant with #[serde(other)] for forward compatibility
- Old nodes silently skip unknown ops instead of crashing
UI fixes:
- Self removed from Following list
- Offline follows in lightbox popup (auto-show if no one online)
- Sent DMs filtered from My Posts
- Comment threading scoped to closest .post (fixes duplicate ID issue)
- Select dropdown text legible in WebKitGTK (black on white options)

Security & stability:
- Incoming auth-fail rate limiting per source IP (3 attempts, then exponential backoff)
- Schema versioning via PRAGMA user_version with migration framework
Networking:
- IPv6 http_addr fix: advertise actual public IPv6 instead of 0.0.0.0
- N2/N3 TTL reduced from 7 days to 5 hours
- Full N1/N2 state re-broadcast every 4 hours
- Bootstrap isolation recovery: 24h check with sticky N1 advertising
- Bidirectional engagement propagation (upstream + downstream)
- Auto downstream registration on pull sync and push notification
- post_upstream table for CDN tree traversal
Media & UI:
- Video preload="auto" for share links and in-app blob URLs
- Following: Online/Offline split with last-seen timestamps
- DMs filtered from My Posts tab
- Image lightbox, audio player, file attachments with download prompt
- Share link unroutable address filtering
