 - v1 is a single-file Python app (`bterminal.py`). Changes are localized.
 - v2 docs are in `docs/`. Architecture decisions are in `docs/task_plan.md`.
 - v2 Phases 1-7 + multi-machine (A-D) + profiles/skills complete. Extras: SSH, ctx, themes, detached mode, auto-updater, shiki, copy/paste, session resume, drag-resize, session groups, Deno sidecar, Claude profiles, skill discovery.
-- v3 Mission Control MVP (Phases 1-5) implemented: project groups, workspace store, 12 new Workspace components, groups.rs backend, SQLite migrations. 138 vitest + 36 cargo tests.
+- v3 Mission Control (All Phases 1-10 Complete): project groups, workspace store, 12 Workspace components, session continuity, workspace teardown, dead v2 component cleanup. 138 vitest + 36 cargo tests.
 - v3 docs: `docs/v3-task_plan.md`, `docs/v3-findings.md`, `docs/v3-progress.md`.
 - Consult Memora (tag: `bterminal`) before making architectural changes.

 - WebKit2GTK has no WebGL — xterm.js must use Canvas addon explicitly.
 - Agent sessions use `@anthropic-ai/claude-agent-sdk` query() function (migrated from raw CLI spawning due to piped stdio hang bug). SDK handles subprocess management internally. All output goes through the adapter layer (`src/lib/adapters/sdk-messages.ts`) — SDK message format matches CLI stream-json.
 - Sidecar uses a single pre-built bundle (`sidecar/dist/agent-runner.mjs`) that runs on both Deno and Node.js. SidecarCommand struct in sidecar.rs abstracts runtime (Deno preferred for faster startup, Node.js fallback). Communicates with Rust via stdio NDJSON. Claude CLI auto-detected at startup via `findClaudeCli()` — checks ~/.local/bin/claude, ~/.claude/local/claude, /usr/local/bin/claude, /usr/bin/claude, then `which claude`. Path passed to SDK via `pathToClaudeCodeExecutable` option. Agents error immediately if CLI not found. CLAUDE* env var stripping is dual-layer: (1) Rust SidecarManager uses env_clear() + envs(clean_env) to strip all CLAUDE* vars before spawning the sidecar process, (2) JS runner also strips via SDK's `env` option (defense-in-depth). Without this, nesting detection triggers when BTerminal is launched from a Claude Code terminal. Session stop uses AbortController.abort() (not process.kill()). `agent-runner-deno.ts` exists as standalone alternative runner but is NOT used by SidecarManager.
-- AgentPane does NOT stop agents in onDestroy — onDestroy fires on layout remounts, not just explicit close. Stop-on-close is handled by TilingGrid.svelte's onClose handler (checks pane type + session status before calling stopAgent).
-- Agent dispatcher (`src/lib/agent-dispatcher.ts`) is a singleton that routes sidecar events to the agent store. Also handles subagent pane spawning (SUBAGENT_TOOL_NAMES detection, toolUseToChildPane routing map).
+- AgentPane does NOT stop agents in onDestroy — onDestroy fires on layout remounts, not just explicit close. Stop-on-close is handled externally (was TilingGrid in v2, now workspace teardown in v3).
+- Agent dispatcher (`src/lib/agent-dispatcher.ts`) is a singleton that routes sidecar events to the agent store. Handles subagent routing (project-scoped sessions skip layout pane, render in TeamAgentsPanel; detached mode creates layout pane). Session persistence via registerSessionProject() + persistSessionForProject() (saves state + messages to SQLite on complete).
 - AgentQueryOptions supports `permission_mode` field (flows Rust -> sidecar -> SDK). Defaults to 'bypassPermissions', supports 'default' mode. allowDangerouslySkipPermissions is conditionally set. Also supports: `setting_sources` (defaults to ['user', 'project']), `system_prompt`, `model`, `claude_config_dir` (for multi-account), `additional_directories`.
 - Claude profiles: claude_list_profiles() reads ~/.config/switcher/profiles/ with profile.toml metadata. Profile selector in AgentPane when >1 profile. Selected profile's config_dir -> claude_config_dir -> CLAUDE_CONFIG_DIR env var override in sidecar.
 - Skill discovery: claude_list_skills() reads ~/.claude/skills/ (dirs with SKILL.md or .md files). claude_read_skill() reads content. AgentPane `/` prefix triggers autocomplete menu. Skill content injected as prompt via expandSkillPrompt().

 - Layout store persists to SQLite on every addPane/removePane/setPreset/setPaneGroup change (fire-and-forget). Restores on app startup via `restoreFromDb()`.
 - Session groups: Pane.group? field in layout store, group_name column in sessions table, collapsible group headers in sidebar. Right-click pane to set group.
 - File watcher uses notify crate v6, watches parent directory (NonRecursive), emits `file-changed` Tauri events.
-- Settings use key-value `settings` table in SQLite (session.rs). Frontend: `settings-bridge.ts` adapter, `SettingsDialog.svelte` component.
+- Settings use key-value `settings` table in SQLite (session.rs). Frontend: `settings-bridge.ts` adapter. v3 uses SettingsTab.svelte (v2 SettingsDialog.svelte deleted in P10).
 - Notifications use ephemeral toast system: `notifications.svelte.ts` store (max 5, 4s auto-dismiss), `ToastContainer.svelte` display. Agent dispatcher emits toasts on agent complete/error/crash.
-- StatusBar component spans full grid width (grid-column: 1 / -1), shows pane counts, active agents, tokens, cost.
+- StatusBar component shows active group name, project count, agent count, tokens, cost. Uses workspace store (v3 rewrite, no longer uses layout store).
 - Agent tree (AgentTree.svelte) uses SVG with recursive layout. Tree data built by `agent-tree.ts` utility from agent messages.
 - ctx integration opens `~/.claude-context/context.db` as SQLITE_OPEN_READ_ONLY — never writes. CtxDb uses Option<Connection> for graceful absence if DB doesn't exist.
 - SSH sessions spawn TerminalPane with shell=/usr/bin/ssh and args array. No SSH library needed — PTY handles it natively.
