[Unreleased]

Added

• CSS relative units rule (.claude/rules/18-relative-units.md): enforces rem/em for layout CSS, px only for icons/borders/shadows

Changed

• GlobalTabBar.svelte CSS converted from px to rem: rail width 2.75rem, button 2rem, gap 0.25rem, padding 0.5rem 0.375rem, border-radius 0.375rem; rail-btn color changed from --ctp-overlay1 to --ctp-subtext0 for better contrast
• App.svelte sidebar header CSS converted from px to rem: padding 0.5rem 0.75rem, close button 1.375rem, border-radius 0.25rem
• Sidebar panel changed from fixed width (28em) to content-driven sizing: width: max-content with min-width: 16em and max-width: 50%; each tab component defines its own min-width: 22em
• Sidebar panel and panel-content overflow changed from hidden to overflow-y: auto to allow content to drive parent width
• SettingsTab.svelte padding converted from px to rem (0.75rem 1rem)
• DocsTab.svelte converted from px to rem: file-picker 14em, picker-title/file-btn/empty padding in rem
• ContextTab.svelte, DocsTab.svelte, SettingsTab.svelte all now set min-width: 22em for content-driven drawer sizing
• UI redesigned from top tab bar + right-side settings drawer to VSCode-style left sidebar: vertical icon rail (GlobalTabBar, 2.75rem, 4 SVG icons) + expandable drawer panel (content-driven width) + always-visible main workspace (ProjectGrid)
• GlobalTabBar rewritten from horizontal text tabs + gear icon to vertical icon rail with SVG icons for Sessions, Docs, Context, Settings; Props: expanded/ontoggle (was settingsOpen/ontoggleSettings)
• Settings is now a regular sidebar tab (not a special right-side drawer); WorkspaceTab type: 'sessions' | 'docs' | 'context' | 'settings'
• App.svelte layout: .main-row flex container with icon rail + optional sidebar panel + workspace; state renamed settingsOpen -> drawerOpen
• Keyboard shortcuts: Alt+1..4 (switch tabs + open drawer), Ctrl+B (toggle sidebar), Ctrl+, (toggle settings), Escape (close drawer)
• SettingsTab CSS: height: 100% (was flex: 1) for sidebar panel context

Added

• SettingsTab split font controls: separate UI font (sans-serif options: System Sans-Serif, Inter, Roboto, Open Sans, Lato, Noto Sans, Source Sans 3, IBM Plex Sans, Ubuntu) and Terminal font (monospace options: JetBrains Mono, Fira Code, Cascadia Code, Source Code Pro, IBM Plex Mono, Hack, Inconsolata, Ubuntu Mono, monospace), each with custom themed dropdown + size stepper (8-24px), font previews in own typeface
• --term-font-family and --term-font-size CSS custom properties in catppuccin.css (defaults: JetBrains Mono fallback chain, 13px)
• Deep Dark theme group: 6 new themes (Tokyo Night, Gruvbox Dark, Ayu Dark, Poimandres, Vesper, Midnight) — total 17 themes across 3 groups (Catppuccin, Editor, Deep Dark). Midnight is pure OLED black (#000000), Ayu Dark near-black (#0b0e14), Vesper warm dark (#101010)
• Multi-theme system: 7 new editor themes (VSCode Dark+, Atom One Dark, Monokai, Dracula, Nord, Solarized Dark, GitHub Dark) alongside 4 Catppuccin flavors
• ThemeId union type, ThemePalette (26-color interface), ThemeMeta (id/label/group/isDark), THEME_LIST registry with group metadata, ALL_THEME_IDS for validation
• Theme store getCurrentTheme()/setTheme() as primary API; deprecated getCurrentFlavor()/setFlavor() wrappers for backwards compat
• SettingsTab custom themed dropdown for theme selection: color swatches (base color per theme), 4 accent color dots (red/green/blue/yellow), grouped sections (Catppuccin/Editor/Deep Dark) with styled headers, click-outside and Escape to close
• SettingsTab global settings section: theme selector, UI font dropdown (sans-serif options), Terminal font dropdown (monospace options), each with size stepper (8-24px), default shell input, default CWD input — all custom themed dropdowns (no native <select>), all persisted via settings-bridge
• Typography CSS custom properties (--ui-font-family, --ui-font-size, --term-font-family, --term-font-size) in catppuccin.css with defaults; consumed by app.css body rule
• initTheme() now restores 4 saved font settings (ui_font_family, ui_font_size, term_font_family, term_font_size) from SQLite on startup alongside theme restoration
• v3 Mission Control (All Phases 1-10 complete): multi-project dashboard with project groups, per-project Claude sessions, team agents panel, terminal tabs, 3 workspace tabs (Sessions/Docs/Context) + settings drawer
• v3 session continuity (P6): persistSessionForProject() saves agent state + messages to SQLite on session complete; registerSessionProject() maps session to project; ClaudeSession.restoreMessagesFromRecords() restores cached messages on mount
• v3 workspace teardown (P7): clearAllAgentSessions() clears agent sessions on group switch; terminal tabs reset via switchGroup()
• v3 data model: groups.rs (Rust structs + load/save ~/.config/bterminal/groups.json), groups.ts (TypeScript interfaces), groups-bridge.ts (IPC adapter), --group CLI argument
• v3 workspace store (workspace.svelte.ts): replaces layout.svelte.ts, manages groups/activeGroupId/activeTab/focusedProjectId with Svelte 5 runes
• v3 SQLite migrations: agent_messages table (per-project message persistence), project_agent_state table (sdkSessionId/cost/status per project), project_id column on sessions
• 12 new Workspace components: GlobalTabBar, ProjectGrid, ProjectBox, ProjectHeader, ClaudeSession, TeamAgentsPanel, AgentCard, TerminalTabs, CommandPalette, DocsTab, ContextTab, SettingsTab
• v3 App.svelte full rewrite: GlobalTabBar + tab content area + StatusBar (no sidebar, no TilingGrid)
• 24 new vitest tests for workspace store, 7 new cargo tests for groups (total: 138 vitest + 36 cargo)
• v3 adversarial architecture review: 3 agents (Architect, Devil's Advocate, UX+Performance Specialist), 12 issues identified and resolved
• v3 Mission Control redesign planning: architecture docs (docs/v3-task_plan.md, docs/v3-findings.md, docs/v3-progress.md), codebase reuse analysis
• Claude profile/account switching: claude_list_profiles() reads ~/.config/switcher/profiles/ directories with profile.toml metadata (email, subscription_type, display_name); profile selector dropdown in AgentPane toolbar when multiple profiles available; selected profile's config_dir passed as CLAUDE_CONFIG_DIR env override to SDK
• Skill discovery and autocomplete: claude_list_skills() reads ~/.claude/skills/ (directories with SKILL.md or standalone .md files); type / in agent prompt textarea to trigger autocomplete menu with arrow key navigation, Tab/Enter selection, Escape dismiss; expandSkillPrompt() reads skill content and injects as prompt
• New frontend adapter claude-bridge.ts: ClaudeProfile and ClaudeSkill interfaces, listProfiles(), listSkills(), readSkill() IPC wrappers
• AgentPane session toolbar: editable working directory input, profile/account selector (shown when >1 profile), all rendered above prompt form
• Extended AgentQueryOptions with 5 new fields across full stack (Rust struct, sidecar JSON, SDK options): setting_sources (defaults to ['user', 'project']), system_prompt, model, claude_config_dir, additional_directories
• 4 new Tauri commands: claude_list_profiles, claude_list_skills, claude_read_skill, pick_directory
• Claude CLI path auto-detection: findClaudeCli() in both sidecar runners checks common paths (~/.local/bin/claude, ~/.claude/local/claude, /usr/local/bin/claude, /usr/bin/claude) then falls back to which/where; resolved path passed to SDK via pathToClaudeCodeExecutable option
• Early error reporting when Claude CLI is not found — sidecar emits agent_error immediately instead of cryptic SDK failure

Changed

• SettingsTab global settings restructured to single-column layout with labels above controls, split into "Appearance" (theme, UI font, terminal font) and "Defaults" (shell, CWD) subsections; all native <select> replaced with custom themed dropdowns
• Font setting keys changed from font_family/font_size to ui_font_family/ui_font_size + term_font_family/term_font_size; UI font fallback changed from monospace to sans-serif
• app.css body font-family and font-size now use CSS custom properties (var(--ui-font-family), var(--ui-font-size)) instead of hardcoded values
• Theme system generalized from Catppuccin-only to multi-theme: all 17 themes map to same --ctp-* CSS custom properties (26 vars) — zero component-level changes needed
• CatppuccinFlavor type deprecated in favor of ThemeId; CatppuccinPalette deprecated in favor of ThemePalette; FLAVOR_LABELS and ALL_FLAVORS deprecated in favor of THEME_LIST and ALL_THEME_IDS

Fixed

• SettingsTab theme dropdown sizing: set min-width: 180px on trigger container, min-width: 280px and max-height: 400px on dropdown menu, white-space: nowrap on option labels to prevent text truncation
• SettingsTab input overflow: added min-width: 0 on .setting-row to prevent flex children from overflowing container
• SettingsTab a11y: project field labels changed from <div><label> to wrapping <label><span class="field-label"> pattern for proper label/input association
• SettingsTab CSS: removed unused .project-field label selector, simplified input selector to .project-field input:not([type="checkbox"])

Removed

• Dead update_ssh_session() method from session.rs and its unit test (method was unused after SSH CRUD refactoring)
• Stale TilingGrid reference in AgentPane.svelte comment (TilingGrid was deleted in v3 P10)

Changed

• StatusBar rewritten for v3 workspace store: shows active group name, project count, agent count instead of pane counts; version label updated to "BTerminal v3"
• Agent dispatcher subagent routing: project-scoped sessions skip layout pane creation (subagents render in TeamAgentsPanel instead); detached mode still creates layout pane
• AgentPane cwd prop renamed to initialCwd — now editable via text input in session toolbar instead of fixed prop

Removed

• Dead v2 components deleted in P10 (~1,836 lines): TilingGrid.svelte (328), PaneContainer.svelte (113), PaneHeader.svelte (44), SessionList.svelte (374), SshSessionList.svelte (263), SshDialog.svelte (281), SettingsDialog.svelte (433)
• Empty component directories removed: Layout/, Sidebar/, Settings/, SSH/
• Sidecar runners now pass settingSources (defaults to ['user', 'project']), systemPrompt, model, and additionalDirectories to SDK query() options
• Sidecar runners inject CLAUDE_CONFIG_DIR into clean env when claudeConfigDir provided in query message (multi-account support)

Fixed

• AgentPane Svelte 5 event modifier syntax: on:click changed to onclick (Svelte 5 requires lowercase event handler attributes, not colon syntax)
• CLAUDE* env var stripping now applied at Rust level in SidecarManager (bterminal-core/src/sidecar.rs): env_clear() + envs(clean_env) strips all CLAUDE-prefixed vars before spawning sidecar process, providing primary defense against nesting detection (JS-side stripping retained as defense-in-depth)

Changed

• Sidecar resolution unified: single pre-built agent-runner.mjs bundle replaces separate agent-runner-deno.ts + agent-runner.ts lookup; same .mjs file runs under both Deno and Node.js
• resolve_sidecar_command() in sidecar.rs now checks deno/node availability upfront before searching paths, improved error message with runtime availability note
• Removed agent-runner-deno.ts from tauri.conf.json bundled resources (only dist/agent-runner.mjs shipped)

Added

• @anthropic-ai/claude-agent-sdk ^0.2.70 npm dependency for sidecar agent session management
• build:sidecar npm script for esbuild bundling of agent-runner.ts (SDK bundled in, no external dependency at runtime)
• permission_mode field in AgentQueryOptions (Rust, TypeScript) — flows from controller through sidecar to SDK, defaults to 'bypassPermissions', supports 'default' mode

Changed

• Sidecar agent runners migrated from raw claude CLI spawning (child_process.spawn/Deno.Command) to @anthropic-ai/claude-agent-sdk query() function — fixes silent hang when CLI spawned with piped stdio (known bug github.com/anthropics/claude-code/issues/6775)
• agent-runner.ts: sessions now use { query: Query, controller: AbortController } map instead of ChildProcess map; stop uses controller.abort() instead of child.kill()
• agent-runner-deno.ts: sessions now use AbortController map; uses npm:@anthropic-ai/claude-agent-sdk import specifier
• Deno sidecar permissions expanded: added --allow-write and --allow-net flags in sidecar.rs (required by SDK)
• CLAUDE* env var stripping now passes clean env via SDK's env option in query() instead of filtering process.env before spawn
• SDK permissionMode and allowDangerouslySkipPermissions now dynamically set based on permission_mode option (was hardcoded to bypassPermissions)
• build:sidecar esbuild command no longer uses --external for SDK (SDK bundled into output)

Fixed

• AgentPane onDestroy no longer kills running agent sessions on component remount — stopAgent() moved from AgentPane.svelte onDestroy to TilingGrid.svelte onClose handler, ensuring agents only stop on explicit user close action

Previously Added

• Exponential backoff reconnection in RemoteManager: on disconnect, spawns async task with 1s/2s/4s/8s/16s/30s-cap backoff, uses attempt_tcp_probe() (TCP-only, no WS upgrade, 5s timeout, default port 9750), emits remote-machine-reconnecting and remote-machine-reconnect-ready events
• Frontend reconnection listeners: onRemoteMachineReconnecting and onRemoteMachineReconnectReady in remote-bridge.ts; machines store sets status to 'reconnecting' and auto-calls connectMachine() on ready
• Relay command response propagation: bterminal-relay now sends structured responses (pty_created, pong, error) back to client via shared event channel with commandId correlation
• send_error() helper in bterminal-relay for consistent error reporting across all command handlers
• PTY creation confirmation flow: pty_create command returns pty_created event with session ID and commandId; RemoteManager emits remote-pty-created Tauri event
• bterminal-core shared crate with EventSink trait: extracted PtyManager and SidecarManager into reusable crate at v2/bterminal-core/, EventSink trait abstracts event emission for both Tauri and WebSocket contexts
• bterminal-relay WebSocket server binary: standalone Rust binary at v2/bterminal-relay/ with token auth (--port, --token, --insecure CLI flags), rate limiting (10 attempts, 5min lockout), per-connection isolated PTY + sidecar managers
• RemoteManager for multi-machine WebSocket connections: v2/src-tauri/src/remote.rs manages WebSocket client connections to relay instances, 12 new Tauri commands for remote operations, heartbeat ping every 15s
• Remote machine management UI in settings: SettingsDialog "Remote Machines" section for add/remove/connect/disconnect
• Auto-grouping of remote panes in sidebar: remote panes auto-grouped by machine label in SessionList
• remote-bridge.ts adapter for remote machine IPC operations
• machines.svelte.ts store for remote machine state management (Svelte 5 runes)
• Pane.remoteMachineId field in layout store for local vs remote routing
• TauriEventSink (event_sink.rs) implementing EventSink trait for Tauri AppHandle
• Multi-machine support architecture design (docs/multi-machine.md): WebSocket NDJSON protocol, pre-shared token + TLS auth, autonomous relay model
• Subagent cost aggregation: getTotalCost() recursive helper in agents store aggregates cost across parent + all child sessions; total cost displayed in parent pane done-bar when children present
• 10 new subagent routing tests in agent-dispatcher.test.ts: spawn, dedup, child message routing, init/cost forwarding, fallbacks (28 total dispatcher tests, 114 vitest tests overall)
• TAURI_SIGNING_PRIVATE_KEY secret set in GitHub repo for auto-update signing
• Agent teams/subagent support (Phase 7): auto-detects subagent tool calls ('Agent', 'Task', 'dispatch_agent'), spawns child agent panes with parent/child navigation, routes messages via parentId field
• Agent store parent/child hierarchy: AgentSession extended with parentSessionId, parentToolUseId, childSessionIds; findChildByToolUseId() and getChildSessions() query functions
• AgentPane parent link bar: SUB badge with navigate-to-parent button for subagent panes
• AgentPane children bar: clickable chips per child subagent with status-colored indicators (running/done/error)
• SessionList subagent icon: subagent panes show '↳' instead of '*' in sidebar
• Session groups/folders: group_name column in sessions table, setPaneGroup in layout store, collapsible group headers in sidebar with arrow/count, right-click pane to set group
• Auto-update signing key: generated minisign keypair, pubkey configured in tauri.conf.json updater section
• Deno-first sidecar: SidecarCommand struct in sidecar.rs, resolve_sidecar_command() prefers Deno (runs TS directly) with Node.js fallback, both runners bundled via tauri.conf.json resources
• Vitest integration tests: layout.test.ts (30 tests), agent-bridge.test.ts (11 tests), agent-dispatcher.test.ts (28 tests) — total 114 vitest tests passing
• E2E test scaffold: v2/tests/e2e/README.md documenting WebDriver approach
• Terminal copy/paste: Ctrl+Shift+C copies selection, Ctrl+Shift+V pastes from clipboard to PTY (TerminalPane.svelte)
• Terminal theme hot-swap: onThemeChange() callback registry in theme.svelte.ts, open terminals update immediately when flavor changes
• Agent tree node click: clicking a tree node scrolls to the corresponding message in the agent pane (scrollIntoView smooth)
• Agent tree subtree cost: cumulative cost displayed in yellow below each tree node label (subtreeCost utility)
• Agent session resume: follow-up prompt input after session completes or errors, passes resume_session_id to SDK
• Pane drag-resize handles: splitter overlays in TilingGrid with mouse drag, supports 2-col/3-col/2-row layouts with 10-90% ratio clamping
• Auto-update CI workflow: release.yml generates latest.json with version, platform URL, and signature from .sig file; uploads as release artifact
• Deno sidecar proof-of-concept: agent-runner-deno.ts with same NDJSON protocol, compiles to single binary via deno compile
• Vitest test suite: sdk-messages.test.ts (SDK message adapter) and agent-tree.test.ts (tree builder/cost), vite.config.ts test config, npm run test script
• Cargo test suite: session.rs tests (SessionDb CRUD for sessions, SSH sessions, settings, layout) and ctx.rs tests (CtxDb error handling with missing database)
• tempfile dev dependency for Rust test isolation

Fixed

• Sidecar env var leak: both agent-runner.ts and agent-runner-deno.ts now strip ALL CLAUDE* prefixed env vars before spawning the claude CLI, preventing silent hangs when BTerminal is launched from within a Claude Code terminal session (previously only CLAUDECODE was removed)

Changed

• RemoteManager reconnection probe refactored from attempt_ws_connect() (full WS handshake + auth) to attempt_tcp_probe() (TCP-only connect, no resource allocation on relay)
• bterminal-relay command handlers refactored: all error paths now use send_error() helper instead of log::error!() only; pong response sent via event channel instead of no-op
• RemoteManager disconnect handler: scoped mutex release before event emission to prevent deadlocks; spawns reconnection task
• PtyManager and SidecarManager extracted from src-tauri to bterminal-core shared crate (src-tauri now has thin re-export wrappers)
• Cargo workspace structure at v2/ level: members = [src-tauri, bterminal-core, bterminal-relay], Cargo.lock moved from src-tauri/ to workspace root
• agent-bridge.ts and pty-bridge.ts extended with remote routing (check remoteMachineId, route to remote_* commands)
• Agent dispatcher refactored to split messages: parentId-bearing messages routed to child panes via toolUseToChildPane Map, main session messages stay in parent
• Agent store createAgentSession() now accepts optional parent parameter for registering bidirectional parent/child links
• Agent store removeAgentSession() cleans up parent's childSessionIds on removal
• Sidecar manager refactored from Node.js-only to Deno-first with Node.js fallback (SidecarCommand abstraction)
• Session struct: added group_name field with serde default
• SessionDb: added update_group method, list/save queries updated for group_name column
• SessionList sidebar: uses Svelte 5 snippets for grouped pane rendering with collapsible headers
• Agent tree NODE_H increased from 32 to 40 to accommodate subtree cost display
• release.yml build step now passes TAURI_SIGNING_PRIVATE_KEY and PASSWORD env vars from secrets
• release.yml uploads latest.json alongside .deb and .AppImage artifacts
• vitest ^4.0.18 added as npm dev dependency
