# BTerminal — Project Guide for Claude

## Project Overview

Terminal emulator with SSH and Claude Code session management. v1 (GTK3+VTE Python) is production-stable. v2 redesign (Tauri 2.x + Svelte 5 + Claude Agent SDK) Phases 1-7 + multi-machine (A-D) + profiles/skills complete. Packaging: .deb + AppImage via GitHub Actions CI. v3 Mission Control (All Phases 1-10 Complete + Production Readiness): multi-project dashboard with project groups, per-project Claude sessions with session continuity, team agents panel, terminal tabs, VSCode-style left sidebar, multi-agent orchestration (Tier 1 management agents: Manager/Architect/Tester/Reviewer with role-specific tabs, btmsg inter-agent messaging, bttask kanban task board with optimistic locking). Production features: sidecar crash recovery/supervision, FTS5 full-text search, plugin system (sandboxed, 35 tests), Landlock sandboxing, secrets management (system keyring), OS + in-app notifications, keyboard-first UX (18+ palette commands), agent health monitoring + dead letter queue, audit logging, error classification. Hardening: TLS relay support, WAL checkpoint (5min), subagent delegation fix.

- 17 themes in 3 groups: 4 Catppuccin (Mocha default) + 7 Editor + 6 Deep Dark (Tokyo Night, Gruvbox Dark, Ayu Dark, Poimandres, Vesper, Midnight)
- CSS uses rem/em for layout; px only for icons/borders (see `.claude/rules/18-relative-units.md`)
- Session configs stored as JSON
- Single-file Python app (v1) — will change to multi-file Rust+Svelte (v2)
- Polish language in some code comments (v1 legacy)
