# BTerminal v3 — Research Findings
## Current Codebase Reuse Analysis
## Adversarial Review Results (2026-03-07)
### Can Reuse (with modifications)
- **Agent session infrastructure**: AgentPane, agent store, agent dispatcher, SDK messages adapter, sidecar bridge — core agent functionality stays
- **Terminal infrastructure**: TerminalPane, pty-bridge — terminal rendering unchanged
- **Markdown rendering**: MarkdownPane, highlight utils — markdown viewer stays
- **Sidecar management**: SidecarManager, agent-runner.mjs — backend agent orchestration
- **PTY management**: PtyManager — backend terminal management
- **Session persistence**: session-bridge, SessionDb — needs schema extension for projects
- **Theme system**: theme store, catppuccin CSS — visual layer unchanged
- **Notification system**: toast notifications — stays as-is
- **Claude bridge**: profiles + skills — reusable per project
- **StatusBar**: needs redesign but concept stays
### Agent: Architect (Advocate)
- Proposed full component tree, data model, 10-phase plan
- JSON config at `~/.config/bterminal/groups.json`
- Single shared sidecar (multiplexed sessions)
- ClaudeSession + TeamAgentsPanel split from AgentPane
- SQLite tables: agent_messages, project_agent_state
- MVP at Phase 5
### Must Replace
- **Layout store**: Current pane-based grid system → project-based workspace system
- **TilingGrid**: CSS Grid tiling → project box layout with internal structure
- **SessionList sidebar**: Pane list → project/group navigation
- **App.svelte**: Root layout completely changes
- **Settings dialog**: Per-app settings → per-project settings
### Agent: Devil's Advocate
- Found 12 issues, 4 critical:
1. xterm.js 4-instance ceiling (hard OOM wall)
2. Single sidecar SPOF
3. Layout store has no workspace concept
4. 384px per project unusable on 1920px
- Recommended: fix workspace concept, xterm budget, UI density, persistence before anything else
- Proposed suspend/resume ring buffer for terminals
- Proposed per-project sidecar pool (max 3) — deferred to v3.1
### Can Drop
- **Detached pane mode**: Doesn't fit the workspace model
- **Drag-resize splitters**: Project boxes have fixed internal layout
- **Layout presets (1-col, 2-col, etc.)**: Replaced by N-project horizontal layout
- **Remote machine integration**: Defer to v4 (complexity too high to combine)
- **ctx ContextPane**: Becomes a workspace tab instead of a pane type
### Agent: UX + Performance Specialist
- Wireframes for 5120px (5 projects) and 1920px (3 projects)
- Adaptive project count: `Math.floor(width / 520)`
- xterm budget: lazy-init + scrollback serialization
- RAF batching for 5 concurrent streams
- <100ms workspace switch via serialize/unmount/remount
- Memory budget: ~225MB total (within WebKit2GTK limits)
- Team panel: inline >2560px, overlay <2560px
- Command palette: Ctrl+K, floating overlay, fuzzy search
---
## Codebase Reuse Analysis
## Adversarial Agent Findings
### Survives (with modifications)
- TerminalPane.svelte — add suspend/resume lifecycle
- MarkdownPane.svelte — unchanged
- AgentTree.svelte — reused inside ClaudeSession
- ContextPane.svelte — extracted to workspace tab
- StatusBar.svelte — modified for per-project costs
- ToastContainer.svelte — unchanged

- All Rust backend (sidecar, pty, session, ctx, watcher)
- highlight.ts, agent-tree.ts utils
(To be filled by adversarial review agents)
### Replaced
- layout.svelte.ts → workspace.svelte.ts
- TilingGrid.svelte → ProjectGrid.svelte
- PaneContainer.svelte → ProjectBox.svelte
- SessionList.svelte → ProjectHeader + command palette
- SettingsDialog.svelte → SettingsTab.svelte
- AgentPane.svelte → ClaudeSession.svelte + TeamAgentsPanel.svelte
- App.svelte → full rewrite
### Dropped (v3.0)
- Detached pane mode (doesn't fit workspace model)
- Drag-resize splitters (project boxes have fixed internal layout)
- Layout presets (1-col, 2-col, etc.) — replaced by adaptive project count
- Remote machine integration (deferred to v3.1, elevated to project level)

- [x] Added `--group` CLI argument parsing in main.rs
- [x] Wrote 24 vitest tests for workspace store (workspace.test.ts)
- [x] Wrote cargo tests for groups load/save/default
#### Phase 2: Project Box Shell
- [x] Created GlobalTabBar.svelte (Sessions | Docs | Context | Settings)
- [x] Created ProjectGrid.svelte (flex + scroll-snap container)
- [x] Created ProjectBox.svelte (CSS grid: header | session-area | terminal-area)

### User Requirements (verbatim)
### User Requirements
1. Projects arranged in **project groups** (many groups, switch between them)
2. Each group has **up to 5 projects** shown horizontally
3. Group/project config via **main menu** (command palette / hidden drawer, on keystroke)
4. Per-project settings:
- Claude subscription (multi-account via switcher-claude)
- Working directory
- Project icon (nerd font, suggested but settable)
- Project name
- Project identifier (derived from name, lowercase-dashed, settable)
- Project description (optional)
- Enabled flag (bool)
3. Group/project config via **main menu** (command palette / hidden drawer, Ctrl+K)
4. Per-project settings: Claude subscription, working dir, icon (nerd font), name, identifier, description, enabled
5. Project group = workspace on screen
6. Each project box has:
- **Claude session box** (default open, continues previous session)
- **Team agents window** (to the right, shows spawned subagents)
- **Terminal tabs below** (agent terminals + user terminals, tabbed)
7. **3 workspace tabs**:
- Tab 1: Sessions view (described above)
- Tab 2: MD file viewer (auto-discovered from projects, choosable)
- Tab 3: Settings editor (per-project settings)
6. Each project box: Claude session (default, resume previous) + team agents (right) + terminal tabs (below)
7. **4 workspace tabs**: Sessions | Docs | Context | Settings
8. App launchable with `--group <name>` CLI arg
9. JSON config file defines all groups
9. JSON config file defines all groups (`~/.config/bterminal/groups.json`)
10. Session continuity: resume previous + restore history visually
11. SSH sessions: spawnable within a project's terminal tabs or in separate tabs
12. ctx viewer: separate tab
11. SSH sessions: spawnable within a project's terminal tabs
12. ctx viewer: workspace tab #3

## Architecture Questions for Adversarial Review
## Architecture (Post-Adversarial Review)
1. **Config format**: JSON file vs SQLite for group/project definitions?
2. **Layout engine**: How to arrange up to 5 project boxes with internal subdivisions?
3. **Session isolation**: One sidecar per project? Shared sidecar with project context?
4. **State management**: How to handle workspace switching (mount/unmount vs hide/show)?
5. **What survives from v2**: Which components/stores/adapters carry over?
6. **Tab implementation**: Browser-style tabs or Svelte component switching?
7. **Command palette**: Build custom or use a library?
8. **Auto-discovery**: Which MD files to surface per project?
9. **Performance**: 5 projects x (session + agents + terminals) = potentially many active panes
### Adversarial Review Summary
3 agents reviewed the architecture: Architect (advocate), Devil's Advocate (attacker), UX+Performance Specialist.
**12 issues identified by Devil's Advocate. Resolutions:**
| # | Issue | Severity | Resolution |
|---|---|---|---|
| 1 | xterm.js 4-instance ceiling (WebKit2GTK OOM) | Critical | Lazy-init + scrollback serialization. Budget: 4 active xterm, unlimited suspended (text buffer). Enforced in code. |
| 2 | Single sidecar = SPOF for all projects | Critical | Accept for v3.0 (existing crash recovery). Per-project pool deferred to v3.1 if needed. |
| 3 | Session identity collision (sdkSessionId not persisted) | Major | Persist sdkSessionId in SQLite `project_agent_state` table. Per-project CLAUDE_CONFIG_DIR isolation. |
| 4 | Layout store has no workspace concept | Critical | Full rewrite: `workspace.svelte.ts` replaces `layout.svelte.ts`. |
| 5 | 384px per project unusable on 1920px | Major | Adaptive: compute visible count from viewport width (`Math.floor(width / 520)`). 5@5120px, 3@1920px, scroll-snap for rest. min-width 480px. |
| 6 | JSON config + SQLite = split-brain | Major | JSON for groups/projects config (human-editable). SQLite for session state. JSON loaded at startup only, no hot-reload. |
| 7 | Agent dispatcher is global singleton, no project scoping | Major | Add projectId to AgentSession. Dispatcher routes by project. Per-project cleanup on workspace switch. |
| 8 | Markdown discovery undefined | Minor | Priority list: CLAUDE.md, README.md, docs/*.md (max 20). Rust command scans with depth limit. |
| 9 | Keyboard shortcut conflicts (3 layers) | Major | Shortcut manager: Terminal layer (focused only), Workspace layer (Ctrl+1-5), App layer (Ctrl+K, Ctrl+G). |
| 10 | Remote machine support orphaned | Major | Elevate to project level (project.remote_machine_id). Defer integration to v3.1. |
| 11 | No graceful degradation for broken projects | Major | Project health state: healthy/degraded/unavailable/error. Colored dot indicator. |
| 12 | Flat event stream wastes CPU for hidden projects | Minor | Buffer messages for inactive workspace projects. Flush on activation. |

---
## Layout System
### Project Grid (Flexbox + scroll-snap)
```css
.project-grid {
display: flex;
gap: 4px;
height: 100%;
overflow-x: auto;
scroll-snap-type: x mandatory;
}
.project-box {
flex: 0 0 calc((100% - (N-1) * 4px) / N);
scroll-snap-align: start;
min-width: 480px;
}
```
N computed from viewport: `Math.min(projects.length, Math.max(1, Math.floor(containerWidth / 520)))`
### Project Box Internal Layout
```
┌─ ProjectHeader (28px) ──────────────────┐
├─────────────────────┬───────────────────┤
│ ClaudeSession │ TeamAgentsPanel │
│ (flex: 1) │ (240px or overlay)│
├─────────────────────┴───────────────────┤
│ [Tab1] [Tab2] [+] TabBar 26px │
├─────────────────────────────────────────┤
│ Terminal content (xterm or scrollback) │
└─────────────────────────────────────────┘
```
Team panel: inline at >2560px, overlay at <2560px. Collapsed when no subagents.
### Responsive Breakpoints
| Width | Visible Projects | Team Panel |
|-------|-----------------|------------|
| 5120px+ | 5 | inline 240px |
| 3840px | 4 | inline 200px |
| 2560px | 3 | overlay |
| 1920px | 3 | overlay |
| <1600px | 1 + project tabs | overlay |
### xterm.js Budget: 4 Active Instances
| State | xterm? | Memory |
|-------|--------|--------|
| Active-Focused | Yes | ~20MB |
| Active-Background | Yes (if budget allows) | ~20MB |
| Suspended | No (HTML pre scrollback) | ~200KB |
| Uninitialized | No (placeholder) | 0 |
On focus: serialize least-recent xterm scrollback, destroy it, create new for focused tab, reconnect PTY.
### Project Accent Colors (Catppuccin)
| Slot | Color | Variable |
|------|-------|----------|
| 1 | Blue | --ctp-blue |
| 2 | Green | --ctp-green |
| 3 | Mauve | --ctp-mauve |
| 4 | Peach | --ctp-peach |
| 5 | Pink | --ctp-pink |
---
## Sidecar Strategy
**Single shared sidecar** (unchanged from v2). Per-project isolation via:
- `cwd` per query (already implemented)
- `claude_config_dir` per query (already implemented)
- `session_id` routing (already implemented)
No sidecar changes needed for v3.0.
---
## Keyboard Shortcuts
| Shortcut | Action | Layer |
|----------|--------|-------|
| Ctrl+K | Command palette | App |
| Ctrl+G | Switch group (palette filtered) | App |
| Ctrl+1..5 | Focus project by index | App |
| Alt+1..4 | Switch workspace tab | App |
| Ctrl+N | New terminal in focused project | Workspace |
| Ctrl+Shift+N | New agent query | Workspace |
| Ctrl+Tab | Next terminal tab | Project |
| Ctrl+W | Close terminal tab | Project |
| Ctrl+, | Settings tab | App |
| Ctrl+Shift+C/V | Copy/paste in terminal | Terminal |

| Decision | Rationale | Date |
|---|---|---|
| (pending adversarial review) | | |
| JSON for groups config, SQLite for session state | JSON is human-editable, shareable, version-controllable. SQLite for ephemeral runtime state. Load at startup only. | 2026-03-07 |
| Adaptive project count from viewport width | 5@5120px, 3@1920px, scroll-snap for overflow. min-width 480px. Better than forcing 5 at all sizes. | 2026-03-07 |
| Single shared sidecar (v3.0) | Existing multiplexed protocol handles concurrent sessions. Per-project pool deferred to v3.1 if crash isolation needed. Saves ~200MB RAM. | 2026-03-07 |
| xterm budget: 4 active, unlimited suspended | WebKit2GTK OOM at ~5 instances. Serialize scrollback to text buffer, destroy xterm, recreate on focus. PTY stays alive. | 2026-03-07 |
| Flexbox + scroll-snap over CSS Grid | Allows horizontal scroll on narrow screens. Scroll-snap gives clean project-to-project scrolling. | 2026-03-07 |
| Team panel: inline >2560px, overlay <2560px | Adapts to available space. Collapsed when no subagents running. | 2026-03-07 |
| 4 workspace tabs (Sessions/Docs/Context/Settings) | ctx viewer as separate tab per user requirement. Docs auto-discovered from projects. | 2026-03-07 |
| Project accent colors from Catppuccin palette | Visual distinction: blue/green/mauve/peach/pink per slot 1-5. Applied to border + header tint. | 2026-03-07 |
| Remote machines deferred to v3.1 | Elevate to project level (project.remote_machine_id) but don't implement in MVP. | 2026-03-07 |
| Keyboard shortcut layers: App > Workspace > Terminal | Prevents conflicts. Terminal captures raw keys only when focused. App layer uses Ctrl+K/G. | 2026-03-07 |
| AgentPane splits into ClaudeSession + TeamAgentsPanel | Team agents shown inline in right panel, not as separate panes. Saves xterm/pane slots. | 2026-03-07 |
| Unmount/remount on group switch | Serialize xterm scrollbacks, destroy, remount new group. <100ms perceived. Frees ~80MB. | 2026-03-07 |
