New Features

LAN Chat — Decentralized P2P Messaging

Chat directly with other ggcode instances on your local network. No relay server needed.

TUI Quick-Send (# mode):

• Type # to enter chat mode — send LAN Chat messages without opening a panel
• Auto-fills @nick from the last unread message for instant replies
• Type @ for participant autocomplete (humans and agents)
• Press Esc to exit

TUI /chat panel:

• Full message history with broadcast and DM support
• @mention autocomplete for routing messages to specific users or agents
• /nick <name> to set your nickname
• File attachments via drag-and-drop
• @agent message approvals (Y/A/N/R) — route messages to your agent with consent

Desktop GUI:

• LAN Chat sidebar tab with multi-room view (broadcast + DMs)
• Unread badges per room and total badge in sidebar
• Contact list showing online participants
• Inline @agent approvals

Agent integration:

• Agents can use the lanchat tool to send messages, list participants, and read history
• Messages from other instances' agents require approval before reaching your agent

Architecture:

• Discovery: Pure-Go mDNS (_ggcode._tcp) — no external dependencies
• Transport: Direct HTTP between instances (no relay)
• Authentication: Built-in community key for zero-config trust
• Privacy: Messages stay on your LAN

Shell and Chat Modes Independent of Agent State

Shell mode ($/!) and chat mode (#) now work regardless of whether the agent
is running. Previously, both modes were blocked when the agent was busy.

• Shell commands execute immediately without entering the agent queue
• Chat messages are sent via LAN Chat, never reaching the agent
• Esc priority: exits shell/chat mode before offering to cancel the agent
• shellOwnedLoading flag cleanly separates shell loading state from agent loading state

Bug Fixes

• relay: Always forward client messages to server, even when appendEvent() reports dedup. Prevents mobile messages from being silently dropped after relay restarts
• relay: Add nil-guard on stats in handleClientEncrypted for consistency with all other call sites
• winget: Rewrote publish-winget.ps1 to generate complete manifest from scratch (fixes top-level ProductCode and AppsAndFeaturesEntries validation)
• winget: Force top-level Scope: user in manifest patch
• lanchat: Fix handler type mismatch causing panic on key press
• lanchat: WorkspaceMeta struct missing json tags (caused desktop frontend field mismatch)
• lanchat: Desktop LanChatView message dedup — race between initial load and event listener could show duplicate messages
• lanchat: Clear unread count when entering # chat mode with @nick prefill
• a2a: Replaced hashicorp/mdns with pure-Go implementation to fix peer flickering and eliminate CGO dependency
• a2a: Auto-detect default route interface for mDNS advertising (avoids advertising on Docker/VPN interfaces)
• ci: Removed echo-plugin e2e test that failed cross-platform
