Executive Summary + +Void already has the hardest part done: a Terminal Bus (PR #16) with inter-terminal +communication, groups, messaging, shared context, and a `void-ctl` CLI. This is +roughly 2,300 lines of working Rust. + +What's missing is the **intelligence layer** — the part that turns raw +communication primitives into actual swarm behavior. ClawTeam (3.3k stars, +HKUDS/ClawTeam) achieves this in Python with tmux as the visual layer. We're +going to do it in pure Rust with Void's infinite canvas as the visual layer — +which is fundamentally superior because: + +1. **You can see all agents at once** — zoom out. Tmux gives you a fixed grid. +2. **Spatial arrangement conveys meaning** — leader in the center, workers around it. +3. **Canvas elements beyond terminals** — a kanban board and a network graph live + alongside the terminals, all draggable, all zoomable. +4. **GPU-accelerated at 60fps** — animated message particles between agents. + +The deliverable is: **when a user toggles "Orchestration Mode" in the sidebar, +Void transforms from a terminal emulator into an AI swarm cockpit.** + +--- + +## 2.

It appears as if the user typed (or pasted) the text. + +For AI agents specifically, the prompt is sent as a special comment that the +agent can parse: + +```bash +# ─── VOID ORCHESTRATION PROTOCOL ──────────────────────────────── +# You are running inside Void, an infinite canvas terminal emulator +# with built-in swarm intelligence.

They share the same memory space. +They already have `Arc>` handles to each other's state machines. They already +have writers that can inject bytes. They already have grid readers that can extract text. + +The terminals are *already connected*. They just don't know it yet. + +This document describes the system that makes that connection explicit: a Terminal Bus +for in-process communication, an APC escape sequence protocol for child-process access +through the existing PTY pipe, and a Group system that lets terminals form teams — with +one orchestrator directing workers, or peers collaborating as equals. + +The primary use case: an AI agent (Claude Code) running in terminal A orchestrates +other terminals — sending commands, reading output, sharing discoveries — while the +user watches everything happen simultaneously on the infinite canvas. + +### Design Principles + +- **Zero external dependencies for the bus.** The in-process layer uses only `std::sync` + and `std::collections`. No async runtime. No message broker. Just Rust. + +- **No socket, no server, no auth tokens.** Communication happens through the PTY + pipe that already exists, using APC (Application Program Command) escape sequences. + The same pipe that carries keyboard input and terminal output carries orchestration + commands. Cross-platform by default — works identically on Windows, Linux, and macOS. + +- **Opt-in complexity.** A terminal that never joins a group behaves exactly as it does + today. The orchestration system is additive, not invasive. + +- **Shell-native interface.** The `void-ctl` CLI writes APC sequences to stdout and + reads responses from stdin — through the PTY pipe. Any process that can run a shell + command can orchestrate terminals. No SDK required. + +--- + +## 2.

Core Concepts + +### 3.1 Terminal Handle + +A `TerminalHandle` is a lightweight, cloneable reference to a terminal's internal state. +It holds `Arc` clones of the same objects that `PtyHandle` owns. Creating a handle does +not create a new terminal — it creates a *window* into an existing one. + +Since `PtyHandle` already stores `term`, `writer`, `title`, `alive`, `last_input_at`, +and `last_output_at` as `Arc>` / `Arc`, cloning these Arcs into a +TerminalHandle is zero-cost and does not change PtyHandle's ownership model. + +### 3.2 Terminal Group + +A group is a named collection of terminals that can communicate. Groups have two modes: + +**Orchestrated Mode**: One terminal is the orchestrator (parent). It can send commands +to workers, read their output, and manage their lifecycle. Workers know who their parent +is and can send messages back. This is the model for AI agent orchestration. + +``` + ┌──────────────┐ + │ Orchestrator │ + │ (Term A) │ + └──┬─────┬──────┘ + │ │ + ┌────▼──┐ ┌▼──────┐ + │Worker │ │Worker │ + │(Term B)│ │(Term C)│ + └───────┘ └────────┘ +``` + +**Peer Mode**: All terminals are equal. Any member can send to any other member. There +is no parent. This is the model for collaborative workflows where multiple agents +work on different aspects of a problem and share findings. + +``` + ┌────────┐ ┌────────┐ + │ Peer A │◄───►│ Peer B │ + └────┬────┘ └────┬────┘ + │ │ + │ ┌────────┐ │ + └──► Peer C ◄──┘ + └────────┘ +``` + +### 3.3 Terminal Status + +Each terminal in a group has a status that is visible in its title bar: + +| Status | Meaning | Title Indicator | +|-----------|------------------------------------------------|-----------------| +| `idle` | Shell prompt visible, waiting for input | `[group ▲ idle]` or `[group ▼ idle]` | +| `running` | Command is executing, output is flowing | `[group ▼ running]` | +| `waiting` | Waiting for input or for another terminal | `[group ▼ waiting]` | +| `done` | Last command completed, results available | `[group ▼ done]` | +| `error` | Last command failed (non-zero exit or timeout) | `[group ▼ error]` | + +The `▲` arrow indicates orchestrator. The `▼` arrow indicates worker. The `◆` diamond +indicates peer mode. + +### 3.4 Shared Context + +The shared context is a key-value store scoped to the entire bus (global) or to a +specific group (namespaced). It lets terminals share structured data without going +through the terminal's text buffer. + +Context entries have: +- A key (string) +- A value (string, can be multi-line) +- A source terminal ID (who wrote it) +- A timestamp (when it was written) +- An optional TTL (time-to-live, auto-expire) + +### 3.5 Bus Events + +Every significant action on the bus produces an event. Terminals (or internal +subscribers) can subscribe to events with filters: + +- `CommandInjected { source, target, command }` +- `OutputChanged { terminal_id }` +- `StatusChanged { terminal_id, old_status, new_status }` +- `TerminalRegistered { terminal_id }` +- `TerminalExited { terminal_id }` +- `GroupCreated { group_id, name }` +- `GroupMemberJoined { group_id, terminal_id, role }` +- `GroupMemberLeft { group_id, terminal_id }` +- `ContextUpdated { key, source_terminal }` +- `MessageSent { from, to, payload }` + +--- + +## 4.

APC Interception Layer + +### 8.1 Overview + +APC interception lives inside each terminal's existing reader thread. Before PTY output +reaches the VTE parser, the reader scans for `\x1b_VOID;` markers (APC escape sequences). +Matching bytes are extracted, dispatched to the terminal bus, and the response is written +back through the PTY as another APC sequence.

Security Model + +### 14.1 Trust Boundary + +The PTY pipe **is** the authentication. Only the child process of a terminal's shell +(and its descendants) can write to that terminal's PTY stdout. The OS enforces this — +no token needed, no socket to protect. + +This is stronger than token-based auth: +- tmux relies on socket file permissions (can be misconfigured) +- VS Code terminal API uses random tokens (can be leaked via env) +- Jupyter notebooks use token-based auth (visible in process list) + +With APC-over-PTY, there is nothing to leak and nothing to misconfigure. + +### 14.2 Attack Surface + +- **No network surface.** There is no listening socket. Nothing to connect to from + outside the process. Port scanners find nothing. Firewalls are irrelevant. +- **No token to leak.** The only env var is `VOID_TERMINAL_ID`, which is a UUID that + identifies the terminal but does not grant access. Access comes from being a child + process of the terminal's shell. +- **No auth to bypass.** There is no authentication handshake to get wrong. If you can + write to the PTY, you are already inside the trust boundary. + +### 14.3 Process Isolation + +Each terminal's APC interception runs in that terminal's reader thread. A command +received on terminal A's PTY can only identify itself as terminal A — the terminal ID +is set by the reader thread, not by the client. A malicious child process cannot +impersonate another terminal. + +### 14.4 Permission Model + +Within the bus (unchanged from the in-process layer): +- Standalone terminals (not in a group) can be controlled by any terminal via the bus. +- In orchestrated groups, only the orchestrator can inject commands into workers. + Workers can send messages to the orchestrator but cannot inject into each other. +- In peer groups, any peer can inject into any other peer. +- Context is globally readable/writable (scoped by convention, not enforcement). + +--- + +## 15.

The bus is the foundation — fast, safe, and +invisible to terminals that don't use it. The APC layer makes the bus accessible to +child processes through the PTY pipe. The CLI makes the bus accessible to humans and +AI agents. + +The total implementation is approximately: +- Bus + types: ~800 lines of Rust +- APC interception: ~200 lines of Rust +- void-ctl: ~400 lines of Rust +- Title bar rendering: ~100 lines of Rust +- Integration changes: ~100 lines across existing files +- **Total: ~1,600 lines of new Rust code** + +Zero new external dependencies. The void-ctl binary reuses existing `serde_json` and +`uuid` crates. + +Everything stays 100% Rust. Everything works on Windows, Linux, and macOS. +Everything is opt-in.

No Electron, no web stack. Built with eframe/egui + wgpu + +alacritty_terminal + portable-pty. + +**Orchestration** transforms Void from a terminal emulator into an AI swarm +cockpit. The user toggles a single switch in the sidebar, and Void: + +1. Spawns a **leader** terminal running Claude Code (or any AI agent) +2. Injects a **coordination protocol** into the leader's system prompt +3. The leader uses `void-ctl` to spawn **worker** terminals +4. Workers receive their own protocol and start executing tasks +5. A **kanban board** on the canvas shows real-time task progress +6. A **network graph** visualizes agent communication with animated particles +7. **Bezier edge lines** connect terminal panels showing message flow +8. All coordination happens through a **Terminal Bus** — a central registry + with IPC over localhost TCP + +The entire system is ~15,000 lines of Rust across 31 files. It compiles to a +single binary. No external dependencies beyond the AI agents themselves. + +### Why This Matters + +The AI agent landscape in 2026 is fragmented: +- **Claude Code** runs in a single terminal +- **ClawTeam** orchestrates multiple agents but requires tmux + Python +- **Cursor/Windsurf** offer multi-file editing but no true multi-agent coordination +- **aider** is single-agent +- **Codex CLI** is single-agent + +Void's orchestration makes multi-agent development **visual, native, and zero-config**. +You don't install Python. You don't configure tmux. You press a button and watch +AI agents coordinate on an infinite canvas. + +### Key Metrics + +| Metric | Target | Rationale | +|--------|--------|-----------| +| Time to first orchestration | < 3 seconds | One sidebar click | +| Agent spawn latency | < 500ms | PTY + Claude boot | +| Bus message latency | < 1ms | Localhost TCP | +| Canvas render @ 5 agents | 60 FPS | GPU-accelerated | +| Canvas render @ 20 agents | 30+ FPS | Graceful degradation | +| Memory per agent | < 50 MB | PTY + term state | +| void-ctl round trip | < 5ms | JSON-RPC over TCP | +| Task state sync | Every frame | Real-time kanban | + +--- + +## 2. Problem Statement + +### The Multi-Agent Gap + +Modern AI coding agents are powerful individually but struggle to coordinate: + +**Problem 1: No Shared Workspace** +When you run two Claude Code instances, they have no awareness of each other. +They might edit the same file simultaneously, causing conflicts. There's no +way for one to say "wait, I'm working on auth — don't touch that module." + +**Problem 2: No Task Decomposition** +A human must manually break work into pieces, paste each piece into a +separate terminal, then manually collect results. There's no automated +"here's the goal, figure out who does what." + +**Problem 3: No Visibility** +With tmux or multiple terminal windows, you can only see one pane at a time +(or a cramped split). You can't zoom out and see the whole operation. +You can't see which agent is idle, which is stuck, which is done. + +**Problem 4: No Communication Channel** +Agents can't share context. If Agent A discovers that the API uses JWT tokens, +Agent B (working on the frontend) has no way to learn this without human +intervention. + +**Problem 5: No Conflict Resolution** +When two agents edit the same file, you get merge conflicts. There's no +mechanism for git worktree isolation or coordinated file locking. + +### The Void Solution + +Void solves all five problems with a single integrated system: + +| Problem | Solution | Mechanism | +|---------|----------|-----------| +| No shared workspace | Terminal Bus | Central registry + groups | +| No task decomposition | Task system + leader protocol | Kanban + void-ctl | +| No visibility | Infinite canvas | Zoom out = see everything | +| No communication | Context store + messaging | void-ctl message/context | +| No conflict resolution | Git worktrees | Per-agent branch isolation | + +--- + +## 3.

Design Principles + +### 4.1 One-Click Activation + +Orchestration must be zero-config. The user clicks "Orchestration" in the +sidebar, and everything happens automatically: +- Leader terminal spawns +- Claude launches with protocol injected +- Kanban board appears on canvas +- Network graph appears on canvas +- Existing terminals join as workers + +No TOML editing. No command-line flags. No configuration files. + +### 4.2 Canvas-Native + +Every orchestration element lives on the infinite canvas as a first-class +panel. Kanban boards, network graphs, terminals — all are draggable, resizable, +zoomable. The user arranges them however they want. + +### 4.3 Agent-Agnostic + +The orchestration protocol works with any AI agent that can run shell commands: +- Claude Code (`claude`) +- OpenAI Codex CLI (`codex`) +- aider (`aider`) +- Custom agents +- Even plain bash scripts + +The only requirement is that the agent can execute `void-ctl` commands. + +### 4.4 Observable by Default + +The user should never wonder "what's happening?" The kanban board shows task +state. The network graph shows communication. Edge overlays show message flow. +Status indicators show which agents are working vs. idle. + +### 4.5 Fail Gracefully + +If an agent crashes, the terminal shows it. If a task fails, the kanban shows +it. If the bus server dies, terminals still work as normal terminals. Orchestration +is a layer on top — removing it doesn't break anything. + +### 4.6 Single Binary + +The entire orchestration system compiles into the `void` binary. `void-ctl` is +a separate binary in the same Cargo workspace. No external processes, no daemons, +no Python, no Node.js. + +--- + +## 5.

Terminal Bus — The Foundation + +### 7.1 Overview + +The Terminal Bus is the central nervous system of Void's orchestration. It's a +struct that lives in `VoidApp` behind `Arc>` and provides: + +1. **Terminal Registry** — knows every terminal's ID, PTY writer, term state +2. **Group Management** — orchestrated (leader/worker) or peer mode +3. **Command Injection** — write bytes into any terminal's PTY +4. **Output Reading** — read any terminal's screen or scrollback +5. **Status Tracking** — idle detection, manual status updates +6. **Task System** — create, assign, track tasks with dependencies +7. **Context Store** — shared key-value with TTL and group scoping +8. **Messaging** — direct messages between terminals +9. **Event System** — filtered subscriptions for real-time updates + +### 7.2 Struct Definition + +```rust +pub struct TerminalBus { + /// All registered terminals, keyed by UUID. + terminals: HashMap, + + /// Terminal status (separate from TerminalHandle to avoid nested locking). + statuses: HashMap, + + /// All active groups, keyed by UUID. + groups: HashMap, + + /// Mapping from terminal ID to its group ID (if any). + terminal_to_group: HashMap, + + /// Shared context store. + context: HashMap, + + /// Event subscribers. + subscribers: Vec<(Uuid, EventFilter, mpsc::Sender)>, + + /// All tasks, keyed by UUID. + tasks: HashMap, + + /// Reverse dependency index: task_id → vec of tasks that depend on it. + task_dependents: HashMap>, + + /// Pending actions that require VoidApp access. + pub pending_spawns: Vec, + pub pending_closes: Vec, +} +``` + +### 7.3 Terminal Handle + +```rust +#[derive(Clone)] +pub struct TerminalHandle { + pub id: Uuid, + pub term: Arc>>, + pub writer: Arc>>, + pub title: Arc>, + pub alive: Arc, + pub last_input_at: Arc>, + pub last_output_at: Arc>, + pub workspace_id: Uuid, +} +``` + +The `TerminalHandle` is intentionally lightweight — it's a collection of `Arc` +references to the `PtyHandle`'s internal state. Cloning a handle is cheap +(just incrementing reference counts). The bus never owns the terminal — it just +has a view into it. + +### 7.4 Terminal Registration Flow + +``` +PtyHandle::spawn() + │ + ├── Creates: term, writer, alive, title, last_input_at, last_output_at + │ (all wrapped in Arc> or Arc) + │ + ├── Spawns 3 threads: reader, event, waiter + │ + └── Returns PtyHandle to Workspace::spawn_terminal() + +Workspace::spawn_terminal() + │ + ├── Creates TerminalPanel with PtyHandle + │ + ├── If bus is available: + │ Builds TerminalHandle from PtyHandle's Arc fields + │ bus.register(handle) + │ │ + │ ├── statuses.insert(id, Idle) + │ ├── terminals.insert(id, handle) + │ └── emit(TerminalRegistered { id, title }) + │ + └── Pushes TerminalPanel into workspace.panels + +Workspace::close_panel_with_bus(idx) + │ + ├── Removes panel from workspace.panels + │ + └── If bus is available: + bus.deregister(id) + │ + ├── Removes from group (if any) + ├── Removes from terminals + statuses + └── emit(TerminalExited { id }) +``` + +### 7.5 Command Injection + +The primary mechanism for inter-terminal control: + +```rust +pub fn inject_bytes( + &mut self, + target: Uuid, + bytes: &[u8], + source: Option, +) -> Result<(), BusError> +``` + +**Process:** +1. Look up target in `terminals` HashMap +2. Check if target is alive (`AtomicBool::load`) +3. Check injection permission (orchestrator → worker only in orchestrated mode) +4. Lock the PTY writer (`Arc>>`) +5. `writer.write_all(bytes)` + `writer.flush()` +6. Update status to Running (if non-empty command) +7. Emit `CommandInjected` event + +**Permission model in orchestrated groups:** +- Orchestrator → any worker: ✅ +- Worker → orchestrator: ✅ (for reporting) +- Worker → other worker: ❌ (must go through orchestrator) +- Outside group → any: ✅ (no restrictions) +- Peer → peer: ✅ (all equal) + +### 7.6 Output Reading + +Two modes of reading terminal content: + +**Screen reading** (`read_screen`): +- Reads the visible screen content (what the user sees) +- Returns one string per screen line +- Fastest — only reads `screen_lines` rows + +**Scrollback reading** (`read_output`): +- Reads the last N lines including scrollback history +- Returns one string per line, most recent last +- Capped at `MAX_READ_LINES` (10,000) for safety +- Used by void-ctl `read` command + +Both methods: +1. Lock the Term state (`Arc>>`) +2. Iterate over the grid cells +3. Build strings character by character +4. Trim trailing whitespace +5. Return `Vec` + +### 7.7 Idle Detection + +**Automatic detection:** +``` +Terminal is considered idle when: + last_output_at.elapsed() >= IDLE_THRESHOLD (2 seconds) +AND started_at.elapsed() > IDLE_THRESHOLD +``` + +**tick_statuses()** — called every frame by VoidApp: +- Scans all terminals with `Running` status +- If output has been silent for 2+ seconds after a command started: + - Transitions to `Done { finished_at: Instant::now() }` + - Emits `StatusChanged` event + +**wait_idle()** — blocking poll (used by void-ctl): +- Takes a handle clone (so bus lock is not held) +- Polls `last_output_at.elapsed()` every 100ms +- Returns when quiet for `quiet_period` or timeout reached + +--- + +## 8. IPC Protocol Design + +### 8.1 Dual Transport: APC + TCP + +Void supports two IPC transports between terminals and the bus: + +**APC (Application Program Command) escape sequences:** +``` +Request: \x1b_VOID;{json_payload}\x1b\\ +Response: \x1b_VOID;{json_response}\x1b\\ +``` + +APC sequences are embedded in the terminal's data stream. The PTY reader +intercepts them before they reach the VTE parser. This is elegant but has +a critical flaw: **Windows conpty strips APC sequences**. + +**TCP (localhost JSON-RPC):** +``` +Request: {"jsonrpc":"2.0","id":1,"method":"list_terminals","params":{}}\n +Response: {"jsonrpc":"2.0","id":1,"result":{...}}\n +``` + +TCP is the primary transport. The bus server listens on `127.0.0.1:{port}` +with an OS-assigned port. The port is exposed via `VOID_BUS_PORT` env var. +void-ctl connects to this port. + +### 8.2 Why Both? + +| Feature | APC | TCP | +|---------|-----|-----| +| Works on Windows | ❌ (conpty strips it) | ✅ | +| Works on Linux | ✅ | ✅ | +| Works on macOS | ✅ | ✅ | +| No external process | ✅ (inline in PTY stream) | ❌ (requires void-ctl) | +| Bidirectional | ✅ | ✅ | +| Latency | ~0 (same process) | ~1ms (TCP roundtrip) | + +In practice, TCP via void-ctl is the canonical path. APC is preserved for +potential future use on Unix systems where inline communication is desirable. + +### 8.3 JSON-RPC 2.0 Protocol + +All bus communication uses JSON-RPC 2.0: + +```json +// Request +{ + "jsonrpc": "2.0", + "id": 1, + "method": "list_terminals", + "params": { + "_caller": "550e8400-e29b-41d4-a716-446655440000" + } +} + +// Success response +{ + "jsonrpc": "2.0", + "id": 1, + "result": { + "terminals": [...] + } +} + +// Error response +{ + "jsonrpc": "2.0", + "id": 1, + "error": { + "code": -32602, + "message": "terminal not found: ..." + } +} +``` + +Every request from void-ctl includes `_caller` — the terminal ID of the +calling terminal. This is used for: +- Permission checks (orchestrator vs. worker) +- Auto-resolving "me" in owner filters +- Workspace-scoped listing + +### 8.4 APC Extraction Algorithm + +The APC extractor handles partial sequences across read boundaries: + +``` +Input stream: [normal bytes...] \x1b_VOID;{json}\x1b\\ [more normal bytes...] + ^ ^ + APC start APC end (ST) + +Output: +- passthrough: [normal bytes...] [more normal bytes...] +- commands: ["{json}"] +``` + +**Boundary handling:** +- If a read boundary falls in the middle of `\x1b_VOID;`, the partial + match is saved in an accumulator +- Next read continues from where accumulation left off +- This handles arbitrarily fragmented reads + +**Terminator:** +- `0x9C` — ST (String Terminator) +- `\x1b\\` — ESC + backslash (alternative ST) +- Both are supported + +--- + +## 9. Security Model + +### 9.1 Threat Surface + +Orchestration introduces new attack vectors: + +| Threat | Vector | Mitigation | +|--------|--------|------------| +| Malicious command injection | Agent sends `void-ctl send "rm -rf /"` | Permission checks in bus | +| Bus server hijacking | External process connects to TCP port | Localhost-only binding | +| Prompt injection via context | Agent puts malicious prompt in context store | Context is data, not commands | +| Agent escape | Worker tries to control orchestrator | Role-based permissions | +| Port scanning | Attacker discovers bus port | Random OS-assigned port | +| File system access via worktrees | Agent modifies files outside worktree | Git worktree boundaries | + +### 9.2 Permission Rules + +**Injection permissions (who can send commands to whom):** + +``` +In Orchestrated Group: + Orchestrator → Worker: ✅ (primary control path) + Worker → Orchestrator: ✅ (for reporting back) + Worker → Worker: ❌ (must go through orchestrator) + +In Peer Group: + Peer → Peer: ✅ (all equal) + +Not in same group: + Any → Any: ✅ (no group restrictions) + +Status setting: + Self → Self: ✅ (always) + Orchestrator → Worker: ✅ (can override) + Worker → Orchestrator: ❌ (denied) + Worker → Worker: ❌ (denied) +``` + +### 9.3 Localhost-Only Binding + +The TCP bus server binds to `127.0.0.1:0` (localhost, random port). This means: +- Only processes on the same machine can connect +- The port is not exposed to the network +- No authentication is needed (same-machine trust) +- The port number is only known to child processes via `VOID_BUS_PORT` + +### 9.4 Claude Code Integration Security + +When launching Claude Code in orchestration mode, we use: +``` +claude --dangerously-skip-permissions --append-system-prompt "..." -p "..." +``` + +The `--dangerously-skip-permissions` flag is required for autonomous operation. +The user accepts this when enabling orchestration. The flag name itself serves +as informed consent. + +**Mitigations:** +- Each worker can be isolated in a git worktree (separate branch) +- The leader protocol explicitly tells agents not to modify critical files +- The kanban board provides visibility into what agents are doing +- The user can always read a worker's terminal output via the network graph + +--- + +## 10. Performance Budget + +### 10.1 Frame Budget + +At 60 FPS, each frame has 16.67ms.

Typical void-ctl calls: +- Request: ~200 bytes (JSON-RPC envelope + params) +- Response: ~500 bytes (result payload) +- Round trip: < 1ms + +Even with aggressive polling (void-ctl task wait at 5s intervals), +the bus server handles < 1 request/second per terminal. + +### 10.4 Scaling Limits + +| Scenario | Terminals | Tasks | FPS | Notes | +|----------|-----------|-------|-----|-------| +| Duo | 2 | 5 | 60 | Sweet spot | +| Trio | 3 | 10 | 60 | Common case | +| Fullstack | 4 | 20 | 60 | Still smooth | +| Research | 6 | 15 | 55+ | Slight pressure | +| Hedge Fund | 8 | 30 | 50+ | Network layout gets busy | +| Stress Test | 20 | 100 | 30+ | Graceful degradation | + +The bottleneck at scale is the network graph's force-directed layout +(O(n²) repulsion forces). Beyond 20 nodes, we should switch to Barnes-Hut +(O(n log n)) but this is a future optimization. + +--- + +# Part III — Core Systems + +--- + +## 11. Terminal Registration & Lifecycle + +### 11.1 Registration + +Every terminal that spawns in Void is automatically registered with the bus: + +```rust +// In Workspace::spawn_terminal() +if let Some(bus) = bus { + let handle = TerminalHandle { + id: panel.id, + term: pty.term.clone(), + writer: pty.writer.clone(), + title: pty.title.clone(), + alive: pty.alive.clone(), + last_input_at: pty.last_input_at.clone(), + last_output_at: pty.last_output_at.clone(), + workspace_id: self.id, + }; + bus.lock().unwrap().register(handle); +} +``` + +The registration is unconditional — every terminal participates in the bus, +whether or not orchestration is active. This means void-ctl works even without +orchestration mode (for power users who want manual control). + +### 11.2 Environment Variables + +When a terminal spawns, its PTY process inherits two env vars: + +``` +VOID_TERMINAL_ID=550e8400-e29b-41d4-a716-446655440000 +VOID_BUS_PORT=54321 +``` + +These are set before the shell starts, so they're available to all child +processes. void-ctl reads them to know its own identity and how to reach the bus. + +### 11.3 Deregistration + +Terminals deregister when: +1. **User closes the panel** — `Workspace::close_panel_with_bus()` +2. **Workspace is deleted** — all panels deregistered +3. **Child process exits** — detected by waiter thread (eventually) + +Deregistration: +1. Removes terminal from its group (if any) +2. If terminal was the orchestrator, dissolves the group +3. Removes from terminals + statuses HashMaps +4. Emits `TerminalExited` event +5. Tasks owned by this terminal are NOT automatically reassigned + (the leader should handle this) + +### 11.4 Terminal Info + +For API responses, terminals are serialized as: + +```rust +pub struct TerminalInfo { + pub id: Uuid, + pub title: String, + pub alive: bool, + pub workspace_id: Uuid, + pub group_id: Option, + pub group_name: Option, + pub role: TerminalRole, + pub status: TerminalStatus, + pub last_output_elapsed_ms: u64, + pub last_input_elapsed_ms: u64, +} +``` + +This is computed on-the-fly from the live `TerminalHandle` + bus state. +It's never cached — always reflects current reality. + +--- + +## 12. Group System + +### 12.1 Group Modes + +**Orchestrated Mode:** +- One terminal is the **orchestrator** (leader) +- All other terminals are **workers** +- Hierarchy is enforced: + - Orchestrator can inject into any worker + - Workers cannot inject into each other + - Workers can message the orchestrator + +**Peer Mode:** +- All terminals are **peers** +- No hierarchy: + - Any peer can inject into any other + - Any peer can set any peer's status + - No concept of leader + +### 12.2 Group Struct + +```rust +pub struct TerminalGroup { + pub id: Uuid, + pub name: String, + pub mode: GroupMode, + pub members: Vec, + pub created_at: Instant, + pub context_prefix: String, +} + +pub enum GroupMode { + Orchestrated { orchestrator: Uuid }, + Peer, +} +``` + +### 12.3 Group Lifecycle + +``` +Create: + bus.create_orchestrated_group("team-1", leader_id) + → Creates group with leader as sole member + → Emits GroupCreated + GroupMemberJoined + +Join: + bus.join_group(terminal_id, group_id) + → Adds terminal to group.members + → Sets terminal_to_group mapping + → Role is determined by group mode (worker or peer) + → Emits GroupMemberJoined + +Leave: + bus.leave_group(terminal_id) + → Removes from group.members + → If orchestrator leaves → dissolve entire group + → If last member leaves → dissolve + → Emits GroupMemberLeft + +Dissolve: + bus.dissolve_group(group_id) + → Removes all member mappings + → Cleans up group-scoped context + → Emits GroupDissolved +``` + +### 12.4 Group Name Uniqueness + +Group names must be unique within the bus. Attempting to create a group with +a duplicate name returns `BusError::GroupNameTaken`. This prevents confusion +when joining groups by name. + +### 12.5 Group Context Scoping + +Each group has a `context_prefix` equal to `"{group_name}:"`.

Auto-Spawn & Auto-Launch + +### 20.1 How void-ctl spawn Works + +When an agent runs `void-ctl spawn`: + +1. void-ctl sends: `{"method": "spawn", "params": {"count": 1, "group": "team-1"}}` +2. Bus server receives the request +3. `dispatch_bus_method("spawn", params, caller_id, bus)` is called +4. The bus pushes to `pending_spawns`: + ```rust + PendingSpawn { + group_name: Some("team-1"), + cwd: None, + title: None, + command: Some("claude"), + } + ``` +5. void-ctl returns: `{"result": {"queued": true}}` + +On the next frame, VoidApp::update() processes `pending_spawns`: + +1. `spawn_terminal()` → creates TerminalPanel + PtyHandle +2. If `group_name` is set: + a. `bus.join_group_by_name(panel_id, group_name)` + b. Write worker protocol to temp file + c. Build claude launch command with protocol + d. `bus.inject_bytes(panel_id, launch_cmd)` +3. If no group but `command` is set: + a. `bus.inject_bytes(panel_id, command + "\r")` + +### 20.2 Auto-Launch Sequence + +The launch command for a worker: + +```bash +claude --dangerously-skip-permissions \ + --append-system-prompt "$(cat '/tmp/void-orchestration-{gid}/worker-{id}.md')" \ + -p "You are a WORKER agent. Check your tasks with void-ctl task list --owner me and start working." +``` + +This means: +1. Terminal spawns with a fresh shell +2. The claude launch command is injected immediately +3. Claude boots up with the worker protocol in its system prompt +4. Claude reads the kick-off message via `-p` +5. Claude runs `void-ctl task list --owner me` to find its tasks +6. Claude starts working + +The worker is fully autonomous from this point. + +### 20.3 PendingSpawn Struct + +```rust +pub struct PendingSpawn { + pub group_name: Option, // auto-join this group + pub cwd: Option, // working directory override + pub title: Option, // panel title + pub command: Option, // command to run after spawn +} +``` + +### 20.4 PendingClose + +Similarly, `void-ctl close ` queues a close: + +```rust +bus.pending_closes.push(target_id); +``` + +VoidApp processes this by finding the panel index and calling +`close_panel_with_bus()`. + +--- + +# Part V — Visual Systems + +--- + +## 21.

Or create a rollback task + +### 46.3 Event Sourcing + +Void's bus event system follows event sourcing principles: + +- Every state change emits an event +- Events are the source of truth for the network visualization +- Events drive the edge overlay animation +- The kanban reads state (not events) for simplicity + +**Full event sourcing would add:** +- Event log persistence (replay past orchestrations) +- Event-driven state reconstruction +- Time-travel debugging + +This is a future roadmap item. + +### 46.4 CQRS (Command Query Responsibility Segregation) + +The bus API naturally follows CQRS: + +**Commands (mutations):** +- `inject`, `set_status`, `group_create`, `group_join`, `group_leave` +- `context_set`, `context_delete`, `message_send` +- `task.create`, `task.update_status`, `task.assign`, `task.delete` +- `spawn`, `close` + +**Queries (reads):** +- `list_terminals`, `read_output`, `wait_idle` +- `group_list` +- `context_get`, `context_list`, `message_list` +- `task.list`, `task.get` + +All commands emit events. All queries are side-effect-free. + +### 46.5 Actor Model + +Each terminal can be viewed as an actor: + +- **State:** Terminal content, status, group membership +- **Mailbox:** PTY stdin (bytes), messages (via context store) +- **Behavior:** Process commands, emit events + +The bus is the actor system: +- Routes messages between actors +- Manages actor lifecycle (register/deregister) +- Provides discovery (list_terminals) + +This is similar to Erlang/OTP or Akka actors, but implemented with +standard Rust concurrency primitives (Arc, Mutex, mpsc). + +--- + +## 47.

Send message: "void-ctl message send 'Health check: are you OK?'" + 2. Read worker output: "void-ctl read --lines 20" + 3. If worker is broken: don't assign more tasks + 4. Create new worker: "void-ctl spawn" +``` + +### 47.6 Competing Consumers Pattern + +Multiple workers compete for unassigned tasks: + +```bash +# Leader creates unassigned tasks +void-ctl task create "Process item 1" # no --assign +void-ctl task create "Process item 2" +void-ctl task create "Process item 3" + +# Workers self-assign +# Worker A: void-ctl task assign +# Worker B: void-ctl task assign +# Worker A finishes, self-assigns: void-ctl task assign +``` + +### 47.7 Priority Queue Pattern + +Tasks with different priorities are processed in order: + +```bash +void-ctl task create "Critical fix" --priority 255 +void-ctl task create "Nice to have" --priority 50 +void-ctl task create "Important feature" --priority 200 +``` + +Workers check `void-ctl task list --owner me` and pick the highest-priority +pending task.
