## Persistent Work Tracking (Beads)

Git-backed work units that survive orchestrator/bot crashes and preserve workflow state.

### Problem

Current workflow: Bot A produces file, instruct Bot B to read it. Works, but if either bot dies or orchestrator crashes, there's no record of:
- What the overall goal was
- What's been completed
- What still needs to be done
- Dependencies between tasks

### Beads Concept

Inspired by [Gas Town's Beads system](https://gastown.dev/). Each work unit is a persistent file (TOML/JSON) storing:

```toml
[bead]
id = "research-arch-001"
title = "Research codebase architecture"
description = "Analyze project structure and document key components"
status = "completed"  # pending | in_progress | completed | failed
assigned_to = "research-bot-a3f2b9d1"
result_file = "/tmp/architecture-overview.md"
created_at = 1739587200
updated_at = 1739590800
depends_on = []  # Array of bead IDs that must complete first
```

### 9P Integration

Expose beads via filesystem:

```
agent/
├── beads/
│   ├── ctl              # "new <title> <role> <description>" creates bead
│   ├── list             # All beads with status
│   └── <bead-id>/
│       ├── status       # pending | in_progress | completed | failed
│       ├── title        # Human-readable name
│       ├── description  # What needs to be done
│       ├── role         # Which type of bot should handle this
│       ├── assigned_to  # Session ID of bot working on it
│       ├── result       # Output/findings (file path or inline text)
│       ├── depends_on   # Newline-separated list of bead IDs
│       └── ctl          # "claim <session-id>", "complete", "fail"
```

### Workflow

1. **Create beads**: Orchestrator or "mayor" bot breaks down goal into beads
2. **Bots claim beads**: Worker bots read `beads/list`, claim pending beads matching their role
3. **Execute**: Bot works on task, writes result
4. **Complete**: Bot marks bead as completed, writes result file path
5. **Crash recovery**: If bot dies, bead remains `in_progress`. Orchestrator can reassign or restart

### Example: Research → Development

```sh
# Create research bead
echo 'new "Research auth system" researcher "Analyze existing auth code"' | 9p write agent/beads/ctl

# Research bot claims it
echo 'claim research-bot-123' | 9p write agent/beads/research-auth-001/ctl

# Bot completes work
echo '/tmp/auth-analysis.md' | 9p write agent/beads/research-auth-001/result
echo 'complete' | 9p write agent/beads/research-auth-001/ctl

# Create dependent dev bead
echo 'new "Implement OAuth" developer "Add OAuth based on research" research-auth-001' | 9p write agent/beads/ctl

# Dev bot waits for dependency, then claims
9p read agent/beads/research-auth-001/status  # → "completed"
echo 'claim dev-bot-456' | 9p write agent/beads/impl-oauth-002/ctl
```

### Benefits

- **Crash resilient**: Work state persists on disk
- **Resumable**: New orchestrator can read beads and continue
- **Auditable**: Git-backed beads provide full history
- **Dependency tracking**: Bots wait for prerequisites automatically
- **Role-based**: Specialized bots pick up beads matching their role

### Git Integration

Commit beads after state changes:
```sh
git add agent/beads/
git commit -m "Completed: Research auth system"
```

Full audit trail of what was done, when, and by whom.

### Philosophy: Precision Over Throughput

Unlike Gas Town's "spawn 30 workers and see what sticks" approach, beads in AnviLLM enable:
- **Deliberate sequencing**: Dependencies ensure work happens in correct order
- **Quality gates**: Beads can require approval before proceeding
- **Traceability**: Every decision and result is recorded
- **Human oversight**: Orchestrator (human or bot) reviews bead results before creating dependent beads

## Approval Gates

Sessions pause for human or coordinator approval before proceeding.

### Use Case

Bot completes a task but shouldn't continue until work is reviewed:
1. Developer bot implements feature
2. Bot writes summary to `out`, transitions to `await_approval`
3. Human/reviewer reads summary, examines changes
4. Human sends approval: `echo 'approve' | 9p write agent/{session}/ctl`
5. Bot continues with next step

### States

Add new state to session lifecycle:
- `idle` → `running` → `await_approval` → `idle` (if approved)
- `idle` → `running` → `await_approval` → `stopped` (if rejected)

### 9P Interface

```
agent/<id>/approval    # Read: current approval status
                       # Write: "approve" or "reject <reason>"
```

### Workflow Example

```sh
# Developer bot context includes:
# "After implementing, write summary to out and request approval"

# Bot finishes work
echo "Implemented OAuth login. Added 3 files, 200 LOC. All tests pass." | 9p write agent/dev-123/out
echo 'request_approval' | 9p write agent/dev-123/ctl

# State transitions to await_approval
9p read agent/dev-123/state  # → "await_approval"

# Human reviews
9p read agent/dev-123/out
git diff

# Approve
echo 'approve' | 9p write agent/dev-123/approval

# Bot continues (or human sends next prompt)
```

### Integration with Beads

Beads can require approval before marking complete:
```toml
[bead]
requires_approval = true
approved_by = ""  # Session ID or "human"
```

Bot completes bead but status stays `pending_approval` until approved.

### Philosophy: Human in the Loop

Approval gates ensure precision:
- Critical changes reviewed before proceeding
- Prevents cascading errors from bad decisions
- Human maintains control over workflow direction
- Bot can work autonomously within approved boundaries

## Convoy (Grouped Work)

Collection of related beads working toward a common goal.

### Concept

Convoy = group of beads + shared context + coordinator

```toml
[convoy]
id = "auth-system-001"
title = "Implement authentication system"
goal = "Add OAuth and session management to application"
status = "in_progress"  # planning | in_progress | completed | failed
coordinator = "planner-bot-789"
created_at = 1739587200
updated_at = 1739590800
beads = [
  "research-auth-001",
  "impl-oauth-002",
  "write-tests-003",
  "review-security-004"
]
```

### 9P Integration

```
agent/
├── convoys/
│   ├── ctl              # "new <title> <goal>" creates convoy
│   ├── list             # All convoys with status
│   └── <convoy-id>/
│       ├── title
│       ├── goal
│       ├── status
│       ├── coordinator  # Session ID managing this convoy
│       ├── beads        # Newline-separated bead IDs
│       ├── context      # Shared context for all beads in convoy
│       └── ctl          # "add_bead <id>", "complete", "abandon"
```

### Workflow

1. **Create convoy**: Planner bot or human defines high-level goal
2. **Break down**: Coordinator creates beads for convoy
3. **Execute**: Worker bots claim and complete beads
4. **Coordinate**: Coordinator monitors progress, creates new beads as needed
5. **Complete**: All beads done, convoy marked complete

### Example

```sh
# Create convoy
echo 'new "Implement auth system" "Add OAuth and session management"' | 9p write agent/convoys/ctl

# Coordinator creates beads
echo 'new "Research auth" researcher "Analyze requirements"' | 9p write agent/beads/ctl
echo 'add_bead research-auth-001' | 9p write agent/convoys/auth-system-001/ctl

echo 'new "Implement OAuth" developer "Add OAuth based on research" research-auth-001' | 9p write agent/beads/ctl
echo 'add_bead impl-oauth-002' | 9p write agent/convoys/auth-system-001/ctl

# Workers execute beads
# Coordinator monitors, adds more beads if needed
# Convoy completes when all beads done
```

### Shared Context

All beads in convoy inherit convoy context:
```
When working on beads in this convoy, remember:
- Target: web application with React frontend
- Security: OWASP top 10 compliance required
- Timeline: 2 weeks
- Constraints: Must integrate with existing user database
```

### Benefits

- **Cohesion**: Related work grouped together
- **Context sharing**: All workers understand overall goal
- **Progress tracking**: See convoy completion percentage
- **Coordination**: Coordinator adjusts plan based on results
- **Resumability**: Convoy persists across crashes

### Philosophy: Deliberate Orchestration

Convoys enable precision through:
- **Explicit goals**: Clear definition of what success looks like
- **Adaptive planning**: Coordinator adjusts based on results
- **Shared understanding**: All workers have convoy context
- **Traceable decisions**: Why each bead was created

Unlike Gas Town's "spawn workers and hope", convoys are deliberate, coordinated, and traceable.

## Conductor Bot

A meta-bot that orchestrates workflows by watching status and dispatching prompts.

### Role

- Monitors status files of worker bots
- Issues coordination prompts when bots enter `await`
- Defines workflow through prompt injection, not hardcoded logic

### Example: Adversarial Review Cycle

Conductor's initial prompt:
```
You are coordinating a code review cycle between 5 reviewer bots and 1 dev bot.

Workflow:
1. Tell reviewers: "Review the code in dev/out, write feedback to your out"
2. Wait for all 5 reviewers to enter await
3. Tell dev: "Read reviewer1/out through reviewer5/out, apply feedback, write updated diff to out"
4. Wait for dev to enter await
5. Repeat from step 1 until reviewers report no issues

Monitor status files. Only proceed when all expected bots are in await.
```

Conductor reads status, sends prompts to `in` files, watches for `await`. The workflow is entirely prompt-driven.

### Benefits

- Workflows defined in natural language, not code
- Easy to modify - just change conductor's prompt
- Conductor can be swapped, forked, or layered (conductor of conductors)
- Worker bots stay simple - they just do tasks and write to `out`

### Conductor as Bot vs External Process

Could be:
- Another LLM bot (flexible, can adapt, but slower and uses tokens)
- A simple script that polls status and sends canned prompts (fast, deterministic)
- Hybrid: script handles timing, bot handles decisions when workflow branches

### 9p-Native Conductor

9p makes coordination trivial. Conductor just reads/writes files - no IPC, no sockets, no message queues. The filesystem *is* the coordination API.

Pseudocode:
```
while true:
    for bot in bots:
        status = read(bot/status)
        if status == "await" and bot in pending:
            next = workflow.next(bot)
            write(next.bot/in, next.prompt)
            pending.remove(bot)
            pending.add(next.bot)
    sleep(poll_interval)
```

Could be 50 lines of rc, Python, or Go. Workflow definitions could be:
- Hardcoded in the conductor
- Loaded from a config file
- Defined in a `workflow` file in 9p itself (conductor reads its own instructions from the filesystem)

## Ephemeral Sessions

Task-oriented sessions that perform a single action then stop automatically.

### Lifecycle

`idle` → `running` → `stopped`

No persistent interaction. Bot receives prompt, executes, writes result to `out`, transitions to `stopped`.

### Design Questions

- **Restartable?** Should `stopped` ephemeral sessions support `restart`, or only `kill`? If restartable, they become regular sessions. If not, simpler lifecycle but less flexible.
- **Non-interactive?** Could enforce no tmux attachment, or allow attachment for debugging but expect no human input.
- **Kill vs Stop?** Maybe ephemeral sessions go straight to `exited` instead of `stopped`. Or use `stopped` but auto-cleanup after some timeout.

### Use Cases

- One-off code reviews: "review this diff" → done
- Batch processing: spawn 10 ephemeral sessions, each processes one file
- Fire-and-forget queries: "what's the status of X?" → answer in `out`, session dies

### Implementation

Flag in session creation: `echo 'new claude /project ephemeral' | 9p write agent/ctl`

Daemon marks session as ephemeral. When backend exits cleanly (not crash), transition to `stopped` or `exited` instead of auto-restart. Optionally auto-cleanup after N seconds.
