gt mq submit: creates task type instead of merge-request type

## Problem

`gt mq submit` creates an issue with `type: task` but should be `type: merge-request`.

## Evidence

```
$ bd show gt-n508
gt-n508: Merge: gt-70b3
Status: open
Priority: P1
Type: task      <-- WRONG, should be merge-request
...
Description:
type: merge-request   <-- Correct type is in description, not in actual type field
```

## Impact

`gt mq list` shows empty queue because it queries for `type: merge-request`

## Fix

`gt mq submit` should set `--type merge-request` when creating the bead.


HOP: Entity chain tracking for agents

Track work history per-entity (CV chains). See ~/ai/stevey-gastown/hop/decisions/002-entity-chains.md for design. Post-v0.1 work.


Update polecat CLAUDE.md with molecule workflow

Add molecule execution guidance to polecat context:

## What to Add

### Molecule Awareness
- Polecats execute Wisps (ephemeral molecule instances)
- The work assignment mail includes molecule context
- Current step is tracked in the wisp

### Workflow Protocol
1. Read assignment (includes molecule ID and current step)
2. Execute current step
3. Update step status via bd mol step
4. Generate summary when all steps complete
5. Run bd mol squash to compress wisp into digest

### Key Commands
- bd mol show <wisp-id> - view current molecule state
- bd mol step <wisp-id> --status=complete - mark step done
- bd mol squash <wisp-id> --summary='...' - complete molecule

### Summary Generation
When completing work, generate a summary that:
- Lists what was accomplished
- Notes any deviations from the plan
- Captures key decisions made
- This becomes the permanent digest


Interactive prompts for destructive operations

Add interactive confirmations for destructive operations.

## Operations Needing Confirmation
- `gt swarm cancel` - Cancels active swarm
- `gt swarm land --force` - Force landing
- `gt polecat decommission` - Removes polecat
- `gt rig remove` - Removes rig
- `gt stop --all` - Stops all sessions
- `gt mail purge` - Permanently deletes mail

## Implementation Options

### Option 1: promptui library
```go
import "github.com/manifoldco/promptui"

prompt := promptui.Prompt{
    Label:     "Delete polecat Toast",
    IsConfirm: true,
}
result, err := prompt.Run()
```

### Option 2: Simple stdin
```go
func confirm(prompt string) bool {
    fmt.Printf("%s [y/N]: ", prompt)
    var response string
    fmt.Scanln(&response)
    return strings.ToLower(response) == "y"
}
```

## Bypass Flags
All confirmations skippable with --force or --yes:
```go
if !force && !confirm("Really cancel swarm?") {
    return nil
}
```

## Acceptance Criteria
- [ ] Destructive ops prompt by default
- [ ] --force or --yes bypasses
- [ ] Clear prompt text explaining action
- [ ] Non-interactive mode (piped input) auto-fails

Work on ga-lzh: Add gt witness attach command. Allow attaching to witness session for a rig, similar to gt mayor attach. When done, submit MR (not PR) to integration branch for Refinery.


Phase 5.1: Document ephemeral architecture

Update docs with ephemeral molecule architecture.

## Files to Update

### docs/architecture.md
- Add Ephemeral Molecules section
- Diagram: Proto → Ephemeral → Digest flow
- Explain inversion of control for summaries

### docs/molecules.md (new or update)
- Proto molecule catalog
- Ephemeral vs main beads
- Molecule lifecycle
- Summary generation guidelines

### Agent CLAUDE.md files
- Polecat: molecule workflow protocol
- Deacon: patrol cycle pattern
- Witness: patrol cycle pattern
- Refinery: patrol cycle pattern

## Key Concepts to Document

1. Everything is a molecule
2. Orchestration molecules are ephemeral
3. Only digests reach main beads
4. Agents generate their own summaries
5. Crash recovery via ephemeral persistence


bd ready --blockers: prioritize issues that block other work

bd ready should prioritize issues that are blocking other work.

**From VC**: Blocker-first prioritization in GetReadyWork(). ~100 lines.
Algorithm: baseline-failure first, then discovered:blocker, then by priority.

**Gas Town implementation**: CLI flag or default behavior:
```bash
bd ready --blockers-first  # Or make this default
```

Checks dependency graph. Issues with many dependents surface first.

**Value**: Unblocks parallelism faster. Critical path gets cleared.

**VC lesson**: Without blocker priority, work can starve on discovered issues.


gt mq reject: manual MR rejection

Implement 'gt mq reject <id> --reason "..."' for manual rejection.

Actions:
1. Verify MR exists and is open
2. Close MR with close_reason=rejected
3. Notify worker via mail (optional)
4. Do NOT close source issue (work not done)

Options:
- --reason REASON: required explanation
- --notify: send mail to worker

Reference: docs/merge-queue-design.md#cli-commands


Slim down rig root config.json to identity only

Rig root config.json should only contain identity:
- type, version, name, git_url, beads.prefix, created_at
- Remove any behavioral config (move to settings/config.json)
- Update RigConfig type to separate identity from settings
- Ensure loader reads identity from root, settings from settings/


Molecule converge: iterate until AI says done

Work isn't 'done' until AI is confident it's done. Fixes the 85% problem.

**From VC**: internal/iterative/converge.go - 3-7 iterations with AI convergence detection. ~600 lines.
Target: 20%+ more issues discovered. Observed: ~25% average improvement.

**Gas Town implementation**: Molecule converge config:
```yaml
converge:
  strategy: ai
  min_iterations: 3
  max_iterations: 7
  confidence: 0.85
```

Polecat iterates, AI checks convergence. Stop when AI is confident or max reached.

**Value**: Raw agents get to ~85% and stop. Iteration catches the remaining 15%.

**VC metrics**: Convergence rate >70%, mean 4-5 iterations for complex work.


Deacon Kernel: event processing molecule architecture

Extend the Deacon from "health orchestrator" to "event processing kernel" that runs a
molecule (rounds) each wake cycle, like an OS kernel scheduler.

## Core Insight

The Deacon already has:
- Wake cycle (daemon poke, timer, lifecycle request)
- Mail as event queue
- Health scanning
- Lifecycle processing

But it is REACTIVE. This epic makes it PROACTIVE with a structured molecule:

```
Deacon Wake
├── Step 0: Session Check (should I cycle myself?)
├── Step 1: Health Scan (Mayor, Witnesses, Crew, Refineries)
├── Step 2: Lifecycle Processing (cycle/restart/shutdown requests)
├── Step 3: Plugin Execution (scheduled, event-triggered, human-requested)
├── Step 4: Event Callbacks (timers, subscriptions)
└── Step 5: Heartbeat + Wait
```

## Key Design Decisions

1. **Session cycling first** - Token costs are quadratic with session length.
   Deacon should aggressively cycle to fresh sessions. First step of every
   wake is "do I need a new session?" based on context budget.

2. **Pinned bead with marching orders** - A pinned bead (like gt prime for
   agents) defines the Deacon's rounds molecule. This is the Deacon's
   "kernel" - its operating loop.

3. **Keepalive file for daemon quieting** - Instead of daemon tmux-poking
   the Deacon (which interrupts work), Deacon writes a keepalive file.
   Daemon reads it and backs off. Worst case: Deacon forgets, gets one
   extra heartbeat it squelches.

4. **Molecule-based rounds** - The wake cycle becomes a molecule with steps.
   Each step can have plugins (inline attention). Steps can be added/modified
   by updating the pinned bead.

## Architecture

```
Go Daemon (minimal, dumb)
├── Reads {townRoot}/deacon/keepalive.json
├── If fresh: do nothing
├── If stale: poke Deacon (fallback)
└── Process lifecycle requests (still daemon's job)

Deacon (Claude agent, smart)
├── Wakes: poke, timer, mail event
├── Writes keepalive (quiets daemon for duration of rounds)
├── Runs rounds molecule:
│   ├── session-check: cycle if context budget low
│   ├── health-scan: check agents, remediate
│   ├── lifecycle: process requests
│   ├── plugins: run scheduled/triggered plugins
│   ├── events: process timer/event callbacks
│   └── complete: update heartbeat, wait
└── Reads marching orders from pinned bead
```

## Relation to Existing Work

- Extends gt-5af (Deacon infrastructure) - CLOSED
- Relates to gt-axz (Plugin architecture) - P3
- Fits into phase3-deacon of gt-ngpz (Christmas Plan)
- Enables gt-976 (Crew lifecycle) as part of health-scan step

Work on ga-y6b: Implement Refinery as Claude agent. Convert from shell to Claude agent that processes MRs in merge queue, runs tests, merges to integration branch. When done, submit MR (not PR) to integration branch for Refinery.


Failure handling: assign back to worker, add labels

Handle merge failures appropriately.

Failure types and actions:
| Failure     | Action                                      |
|-------------|---------------------------------------------|
| conflict    | Add needs-rebase label, assign to worker    |
| tests_fail  | Add needs-fix label, assign to worker       |
| build_fail  | Add needs-fix label, assign to worker       |
| flaky_test  | Retry once, then treat as tests_fail        |
| push_fail   | Retry with backoff, escalate if persistent  |

Actions:
1. bd update <id> --status=open --assignee=<worker>
2. bd update <id> --labels=<failure-label>
3. Send mail to worker explaining failure
4. Log failure details

Reference: docs/merge-queue-design.md#handling-failures


Polecats should not push branches to remote

## Current Behavior

Polecats push their branches to origin (e.g., `polecat/furiosa`), which pollutes the remote with many short-lived branches.

## Desired Behavior

Polecats should only commit locally. The Refinery handles all remote pushes:
1. Polecat works on local `polecat/<name>` branch
2. Polecat signals done (state → idle)
3. Refinery pulls from local polecat branch
4. Refinery runs tests, merges to main
5. Refinery pushes main to remote
6. If PR review needed, Refinery creates the PR

## Benefits

- Clean remote (no branch pollution)
- Clear responsibility (Refinery is the quality gate)
- Simpler cleanup (local branches deleted with worktree)
- Less noise in GitHub UI

## Trade-offs

- If polecat crashes before Refinery merges, code is lost locally
- But beads issue remains open, another polecat can redo the work
- This is acceptable for ephemeral workers

## Implementation

In polecat CLAUDE.md or landing protocol:
- Remove `git push origin HEAD` from workflow
- Replace with just `git commit` + signal done
- Refinery handles the rest


Phase 4.2: Witness/Refinery patrol molecules

Extend ephemeral patrol pattern to Witness and Refinery.

## Witness Patrol Cycle

mol-witness-patrol-cycle:
1. scan-polecats: Check each polecat status
2. detect-stalls: Find stuck/idle polecats
3. nudge-or-escalate: Take action on stalls
4. log-status: Record cycle results
→ Squash with summary

## Refinery Patrol Cycle

mol-refinery-patrol-cycle:
1. scan-queue: Check merge queue
2. process-ready: Merge ready MRs
3. handle-failures: Deal with conflicts/failures
4. log-status: Record cycle results
→ Squash with summary

## Quiescent Mode

When no work: just log 'no activity' summary.
Witness and Refinery can sleep between cycles until triggered.


mol-deacon-patrol

CLI: polecat commands (add, remove, list, wake, sleep)

Polecat management CLI commands.

## Commands

### gt polecat list
List polecats in a rig.
```
gt polecat list <rig> [--json]
gt polecat list --all [--json]
```
Output:
- Name
- State (idle/active/working/done/stuck)
- Current issue (if any)
- Session status (running/stopped)

### gt polecat add
Add a new polecat to a rig.
```
gt polecat add <rig> <name>
```
- Creates polecat directory
- Clones rig repo
- Creates work branch
- Initializes state

### gt polecat remove
Remove a polecat from a rig.
```
gt polecat remove <rig>/<polecat> [--force]
```
- Fails if session running
- Warns if uncommitted changes
- --force bypasses checks

### gt polecat wake
Mark polecat as active (ready for work).
```
gt polecat wake <rig>/<polecat>
```
Transitions: idle → active

### gt polecat sleep
Mark polecat as idle (not available).
```
gt polecat sleep <rig>/<polecat>
```
Transitions: active → idle
Fails if session running (stop first).

## Address Format

`<rig>/<polecat>` for operations on specific polecat.
`<rig>` for list command.

## Implementation

```go
var polecatCmd = &cobra.Command{Use: "polecat"}
polecatCmd.AddCommand(listCmd, addCmd, removeCmd, wakeCmd, sleepCmd)
```


detectSender() doesn't recognize crew workers

## Problem

`detectSender()` in mail.go only detects polecats, not crew workers.

## Current Code (line 445)

```go
// If in a rig's polecats directory, extract address
if strings.Contains(cwd, "/polecats/") {
    // extract rig/polecat
}

// Default to mayor
return "mayor/"
```

## Symptom

Emma (crew worker at `/Users/stevey/gt/beads/crew/emma`) runs:
- `gt mail inbox` → checks `mayor/` inbox (wrong!)
- Should check `beads/emma` or `beads/crew/emma`

## Fix

Add crew detection:
```go
// If in a rig's crew directory, extract address
if strings.Contains(cwd, "/crew/") {
    parts := strings.Split(cwd, "/crew/")
    if len(parts) >= 2 {
        rigPath := parts[0]
        crewName := strings.Split(parts[1], "/")[0]
        rigName := filepath.Base(rigPath)
        return fmt.Sprintf("%s/%s", rigName, crewName)
    }
}
```

## Also Check

- `gt prime` correctly detects role, so there may be another detection function that works
- Should unify detection logic


Rename .beads-ephemeral to .beads-wisps in docs

The wisp storage directory should be named `.beads-wisps/` not `.beads-ephemeral/`.

Also fix the architecture: Witness and Refinery share mayor/rig's beads and wisps.
They don't have separate ephemeral stores.

## Files to update
- docs/wisp-architecture.md
- docs/architecture.md
- ~/gt/docs/patrol-system-design.md
- ~/gt/CLAUDE.md

## Changes
1. Rename `.beads-ephemeral/` → `.beads-wisps/` everywhere
2. Remove incorrect references to witness/.beads-ephemeral/ and refinery/rig/.beads-ephemeral/
3. Clarify that all rig-level patrols use mayor/rig/.beads-wisps/


Patrol System: Agent lifecycle loops with attachments

Enable Gas Town agents to run continuous patrols, survive crashes, and hand off work across sessions.

## Core Concepts
- **Attachments**: Molecules bound to agent's pinned bead until complete
- **Patrols**: Cyclic molecules that loop (deacon, witness, refinery)
- **Quiescent**: Agents that sleep until triggered (witness, refinery)

## Design Doc
See docs/patrol-system-design.md

## Phases
Phase 1: Foundation (attachment field, daemon detection, mol-deacon-patrol)
Phase 2: Quiescent Agents (wake triggers, witness/refinery patrols)
Phase 3: Callbacks and Plugins (mail protocol, plugin runner)
Phase 4: Polish (gt patrol status, metrics, tuning)

## Key Decisions
- Attachment as field on pinned bead (not edge type, for now)
- Mail-based orchestration for all callbacks
- Queue replacement for heartbeat delivery (not pile-up)
- Burn and respawn for patrol loops (not in-place reset)


Remove unused style helper functions

internal/style/style.go defines RenderSuccess, RenderWarning, RenderError, and RenderInfo helper functions that are never used. Code uses style.Success.Render() directly instead. Either use the helpers consistently or remove them.


Phase 1.1: Attachment field on pinned beads

Add attached_molecule field to pinned bead schema.

## Schema Change
Add to handoff/pinned bead issues:
- attached_molecule: string (root issue ID of attached mol)
- attached_at: timestamp

## Implementation
- Update beads Issue struct if needed
- Or: use labels/metadata field
- Ensure bd show displays attachment info

## Acceptance
- Can set/clear attachment on a bead
- bd show displays attachment status


Swarm cleanup: delete merged polecat branches and reset state

After a swarm completes and branches are merged, leftover state remains:

## Current Problem

1. **Remote branches not deleted** - polecat/* branches stay on origin after merge
2. **Polecat clones not reset** - still on old branch with completed work
3. **No cleanup command** - manual cleanup required

## Observed After Swarm

Remote branches still present:
- origin/polecat/Morsov
- origin/polecat/Nux
- origin/polecat/Rictus
- origin/polecat/Slit
- origin/polecat/Toast

## Proposed Solution

Add cleanup commands:

1. gt swarm cleanup <swarm-id> - Clean up after swarm completion
   - Delete remote polecat branches that were merged
   - Reset polecat clones to main
   - Clear issue assignments

2. gt polecat reset <rig>/<polecat> - Reset single polecat
   - git checkout main && git pull
   - Delete local polecat branch
   - Clear current issue assignment

3. Auto-cleanup option on gt session stop --cleanup

## Manual Cleanup For Now

git push origin --delete polecat/Nux polecat/Toast ...
cd polecats/Nux && git checkout main && git pull


gt mail reply/thread: Conversation support

Add mail conversation features:

- gt mail reply <id> -m 'message' - Reply to a message
- gt mail thread <id> - Show all messages in a thread

Enables back-and-forth communication between agents.


Digest: mol-deacon-patrol

Test patrol cycle - first run, no actual work done


Mayor startup protocol prompting

Add startup protocol to Mayor CLAUDE.md template.

## On Session Start

1. Check for handoff:
   town inbox | grep "Session Handoff"

2. If handoff found:
   - Read it: town read <msg-id>
   - Process pending escalations (highest priority)
   - Check status of noted swarms
   - Verify rig health matches notes
   - Continue with documented next steps

3. If no handoff:
   town status     # Overall health
   town rigs       # Each rig
   bd ready        # Work items
   town inbox      # Any messages
   Build your own picture of current state.

4. After processing handoff:
   - Archive or delete the handoff message
   - You now own the current state

## Handoff Best Practices

- Be specific: 'Toast has merge conflict in auth/middleware.go' not 'Toast is stuck'
- Include context: Why decisions are pending, what you were thinking
- Prioritize next steps: What is most urgent
- Note time-sensitive items: Anything that might have changed since handoff


CloudRun cost tracking: Usage monitoring and limits

## Overview

Track Cloud Run usage costs and enforce spending limits.

## Cost Model

Cloud Run pricing (approximate):
- CPU: ~$0.000024/vCPU-second
- Memory: ~$0.0000025/GiB-second
- Requests: ~$0.40/million

For 5-minute worker (2 vCPU, 4GB):
- CPU: 300 × 2 × $0.000024 = $0.0144
- Memory: 300 × 4 × $0.0000025 = $0.003
- **Total: ~$0.017 per session**

## Implementation

```go
type CostTracker struct {
    cpuRate    float64  // per vCPU-second
    memRate    float64  // per GiB-second
    sessions   []SessionCost
    mu         sync.RWMutex
}

type SessionCost struct {
    WorkerID  string
    StartTime time.Time
    EndTime   time.Time
    CPUs      float64
    MemoryGiB float64
}

func (t *CostTracker) RecordSession(workerID string, start, end time.Time, cpus, mem float64) {
    t.mu.Lock()
    defer t.mu.Unlock()
    t.sessions = append(t.sessions, SessionCost{...})
}

func (t *CostTracker) CurrentCost() float64 {
    t.mu.RLock()
    defer t.mu.RUnlock()
    var total float64
    for _, s := range t.sessions {
        duration := s.EndTime.Sub(s.StartTime).Seconds()
        total += duration * s.CPUs * t.cpuRate
        total += duration * s.MemoryGiB * t.memRate
    }
    return total
}
```

## Cost Cap Enforcement

```go
func (o *CloudRunOutpost) Spawn(...) (Worker, error) {
    if o.costCap > 0 && o.costTracker.CurrentCost() >= o.costCap {
        return nil, ErrCostCapExceeded
    }
    // ... spawn worker
}
```

## Config

```yaml
outposts:
  - name: cloudrun-burst
    type: cloudrun
    cost_cap_hourly: 5.00   # Stop spawning if hourly cost exceeds $5
    cost_cap_daily: 50.00   # Daily limit
```

## CLI

```bash
gt outpost status cloudrun-burst
# Shows: Cost (today): $0.42 / $50.00 cap
```

## Files

- `internal/cloudrun/cost.go`

## Dependencies

Depends on: gt-9a2.8 (basic CloudRunOutpost)


Outpost/Worker interfaces: Core abstractions for remote compute

## Overview

Define the core interfaces that all outpost types implement.

## Interfaces

```go
type OutpostType string
const (
    OutpostLocal    OutpostType = "local"
    OutpostSSH      OutpostType = "ssh"
    OutpostCloudRun OutpostType = "cloudrun"
)

type Outpost interface {
    Name() string
    Type() OutpostType
    MaxWorkers() int
    ActiveWorkers() int
    Spawn(issue string, config WorkerConfig) (Worker, error)
    Workers() []Worker
    Ping() error
    SendMail(worker string, msg Message) error  // optional
}

type Worker interface {
    ID() string
    Outpost() string
    Status() WorkerStatus  // idle, working, done, failed
    Issue() string
    Attach() error         // for interactive outposts
    Logs() (io.Reader, error)
    Stop() error
}

type WorkerConfig struct {
    RigPath    string
    BeadsDir   string
    GitBranch  string
    Context    map[string]string  // hints for worker
}
```

## Files

- `internal/outpost/outpost.go` - Outpost interface
- `internal/outpost/worker.go` - Worker interface
- `internal/outpost/config.go` - WorkerConfig, OutpostType

## Notes

This is the foundation for all federation work. Keep interfaces minimal - we can extend later.


Design: Polecat Beads write access

Design for granting polecats direct beads write access.

## Background

With Beads v0.30.0 tombstone-based rearchitecture, we have solid multi-agent support. Reversing the original read-only decision.

## Benefits

- Simplifies architecture (no mail-based issue filing proxy)
- Empowers polecats to file discovered work
- Beads handles work-disavowal

## Complications

For OSS projects where you cannot commit to project .beads/, need per-rig beads repo configuration.

## Subtasks (implementation)

- gt-zx3: Per-rig beads configuration schema
- gt-e1y: Worker prompting updates for beads access
- gt-cjb: Witness proxy removal
- gt-082: Beads sync in decommission checklist

**Design complete.** Each subtask has full specification in its description.


Shutdown request handler

Handle polecat shutdown requests:

When polecat runs 'gt handoff --shutdown':
1. Polecat sends mail to <rig>/witness requesting shutdown
2. Witness receives mail
3. Witness verifies:
   - Git working tree is clean
   - Work is submitted (MR exists or in queue)
   - No uncommitted beads changes
4. If clean:
   - gt session stop <rig>/<polecat>
   - git worktree remove polecats/<name>
   - git branch -d polecat/<name>
5. If not clean:
   - Send nudge back to polecat
   - Track retry count

Depends on fixing gt-dsfi (handoff deadlock).


Merge Queue in Beads: Universal chit system for all work

**Design doc**: docs/merge-queue-design.md


Pinned bead naming convention for all roles

Establish consistent naming convention for pinned beads across all roles.

## Problem

Every role needs a pinned bead for molecule attachment, handoff state, and identity.
We need a consistent naming convention so gt tools can find the pinned bead for any role.

## Proposed Convention

  {role}.pinned                    - Singleton roles (deacon, mayor)
  {rig}-{role}.pinned              - Per-rig roles (witness, refinery)
  {rig}-{name}.pinned              - Named agents (polecats, crew)

Examples:
- deacon.pinned
- mayor.pinned
- gastown-witness.pinned
- gastown-refinery.pinned
- gastown-furiosa.pinned (polecat)
- gastown-max.pinned (crew)

## Storage Location

| Role | Pinned Bead Location |
|------|---------------------|
| Mayor | ~/gt/.beads/ (town level) |
| Deacon | ~/gt/.beads/ (town level) |
| Witness | {rig}/.beads/ (rig level) |
| Refinery | {rig}/.beads/ (rig level) |
| Polecat | {rig}/polecats/{name}/.beads/ |
| Crew | {rig}/crew/{name}/.beads/ |

## Why This Matters

1. Name recycling: Polecats reuse names so their pinned beads persist
2. Molecule attachment: gt mol bond needs to find the pinned bead
3. gt prime: Can show you are working on X from pinned bead
4. Crash recovery: Resume from pinned beads attached molecule

## Tasks

- Document naming convention in architecture.md
- Update gt prime to find pinned bead by convention
- Update gt mol bond to use conventional name
- Create pinned beads on role startup if missing
- Add gt pinned command to show/manage pinned beads

## Related

- gt-rana.1: Attachment field on pinned beads (closed)
- gt-id36.2: Deacon marching orders (pinned bead)


Tmux status line: rig color themes and worker identity display

## Summary

Customize tmux status line for Gas Town workers with:
1. Per-rig configurable color themes
2. Clear worker name and role visibility

## Current Problem

- Only mayor shows in status line (and truncated)
- Can't tell which rig/worker you're looking at
- All sessions look the same

## Proposed Design

### Per-rig colors
```yaml
# In rig config or beads
theme:
  primary: '#ff6600'    # Orange for gastown
  secondary: '#333333'
  accent: '#ffcc00'
```

### Status line format
```
[gastown/Rictus] polecat | gt-70b3 | branch: polecat/Rictus
[beads/emma] crew | working | branch: main
[mayor] coordinator | idle
```

### Components
- Rig name with rig color
- Worker name
- Role (polecat/crew/mayor/witness/refinery)
- Current issue or status
- Branch name

## Configuration

Could use pinned beads for this (see gm-w13, beads-6v2):
- `bd show <rig>-theme` returns theme config
- Stored as pinned bead, always available
- Part of 'config in beads data plane' initiative

Implementation complete. Core features: per-rig color themes, dynamic status line with issue/mail indicators, gt theme/issue commands. Ready for testing.


Epic: Wisp Molecule Integration

## Vision

Integrate Beads wisp molecules into Gas Town. All orchestration work runs as wisp molecules - patrols, polecat workflows, batch operations. Only digests reach main beads.

## The Steam Engine Metaphor

```
Engine does work → generates steam
Steam wisps rise → execution trace
Steam condenses → digest (distillate)
Steam dissipates → cleaned up (burned)
```

## Architecture

```
Proto Molecules (templates)
    ↓ bd mol bond
Wisps (.beads-wisps/ or inline)
    ↓ bd mol squash + AI summary
Main Beads (digests only)
```

## Vocabulary

| Term | Meaning |
|------|---------|
| bond | Attach proto to work (creates wisps) |
| wisp | Temporary execution step (steam rising) |
| squash | Condense wisps into digest |
| burn | Destroy wisps without record |
| digest | Permanent condensed record (distillate) |

## Key Design Decisions

1. **Wisp location**: Per-rig or inline in main beads with wisp flag
2. **Summary generation**: Agent that did work generates summary (inversion of control)
3. **Squash timing**: Final step of molecule workflow, before signaling done
4. **Crash recovery**: Wisps persist, Witness detects stalls, new agent resumes
5. **Patrols**: Each cycle is fresh wisp molecule, squashed on completion

## Digest Contents

- Molecule type and instance ID
- Assignee, start/end times
- Source issue reference
- AI-generated summary
- Outcomes (issues closed, commits, branches)

## Integration Points

- gt rig init: Configure wisp storage
- gt spawn --molecule: Bond creates wisps
- gt prime: Show wisp molecule context
- Polecat CLAUDE.md: Summary + squash protocol
- gt doctor: Wisp health checks
- Deacon/Witness/Refinery: Patrol molecules

## Phases

Phase 1: Wisp setup infrastructure
Phase 2: Spawn integration
Phase 3: Completion flow (summary + squash)
Phase 4: Patrol integration
Phase 5: Documentation and polish


Engineer session restart protocol

Implement session restart flow for when the Engineer needs to split work:

1. Engineer creates subtask(s) in Beads assigned to self
2. Engineer sends handoff mail to self (🤝 HANDOFF)
3. Engineer sends restart request to Witness
4. Witness verifies:
   - Handoff mail exists in Engineer outbox/sent
   - Subtasks filed in Beads
5. Witness restarts the Refinery session (new Engineer context)

This enables "occasionally consistent, eventually convergent" work patterns.
The Refinery continues; the Engineer gets fresh context.


Create Refinery role template

Add Refinery template to internal/templates/roles/:
- refinery.md.tmpl with full role context
- Variables: rig name, working directory, handoff bead ID
- Update SeedRoleTemplates to include it
- gt prime uses this template for Refinery context


Timed Beads: Scheduled recurring work

## Summary

Timed beads wake up periodically and get injected into the ready queue by the daemon.

## Schema Extension

```yaml
id: gt-weekly-sync
type: task  # or sentinel
schedule: "0 9 * * 1"  # cron: Monday 9am
# OR
interval: 24h          # every 24 hours
tier: haiku            # cheap model for routine checks
next_run: 2025-12-20T09:00:00Z
```

## Daemon Integration

Daemon heartbeat loop:
1. Check timed beads where `next_run <= now`
2. For each due bead:
   - Inject into ready queue (set status to open if needed)
   - Update `next_run` based on schedule/interval
3. Witnesses pick up work via `bd ready`

## Use Cases

- Weekly team sync reminders
- Daily health checks
- Periodic cleanup tasks
- Scheduled reports

## Interaction with Pinned Beads

A pinned bead can be timed - it wakes up periodically but never closes.
This is how you model "background services" in Gas Town.


Merge: gt-3x1

branch: polecat/Slit
target: main
source_issue: gt-3x1
rig: gastown


Default polecat names: Mad Max theme instead of AdjectiveNoun

Current default naming for new polecats uses AdjectiveNoun convention.
Since rigs already provide namespacing, we can use more thematic names.

Suggestion: Use Mad Max / Fury Road character and vehicle names as defaults.
Examples: Furiosa, Nux, Slit, Morsov, Toast, Rictus, Warboy, etc.

Could also include:
- War Rig parts: Guzzler, Tanker, Pursuit
- Citadel roles: Imperator, Blackthumb, Organic
- Wasteland terms: Chrome, Witness, Shiny

Implementation:
- Add name generator in internal/polecat/ or similar
- Use when --create flag is used without explicit name
- Cycle through pool to avoid duplicates within a rig


Document harness concept in docs/harness.md

Create comprehensive harness documentation:
- What is a harness (installation directory)
- Recommended structure and naming
- .beads/redirect for default project
- config/ contents (rigs.json, town.json)
- Mayor home vs rig-level mayor/
- Example configurations
- Relationship to rigs


Phase 5.2: Ephemeral error handling and recovery

Handle edge cases in ephemeral molecule lifecycle.

## Scenarios

### Agent dies mid-molecule
- Ephemeral state persists
- Witness detects stall (no heartbeat)
- Options:
  a. Nudge agent to resume
  b. Reassign to new agent
  c. Escalate to Mayor

### Squash fails
- Retry with exponential backoff
- If persistent failure, escalate
- Don't lose the ephemeral state until squash succeeds

### Orphaned molecules
- Molecule started, never completed
- gt doctor detects (>24h old with no activity)
- Options:
  a. Manual review
  b. Auto-abandon with 'abandoned' digest
  c. Reassign

### Ephemeral repo corruption
- Re-init from scratch
- Active molecules are lost
- Main beads is source of truth for assigned work

## Implementation

Add error handling to:
- bd mol bond (handle init failures)
- bd squash (retry logic)
- gt doctor (recovery suggestions)


Add Gas Town theory of operation to all role primings

All roles (Mayor, Witness, Refinery, Polecat) should get basic GT architecture context: harness, rigs, agents, mail, beads workflow


Implement gt mol status command

Show what's on an agent's hook.

```bash
gt mol status [target]
```

Output:
- What's slung (molecule name, associated issue)
- Current phase and progress
- Whether it's a wisp
- Next action hint

If no target, shows current agent's status.

Acceptance:
- [ ] Read pinned bead attachment
- [ ] Display molecule/issue info
- [ ] Show phase progress
- [ ] Indicate wisp vs durable


Merge execution: merge, test, push

Implement the actual merge execution.

Steps:
1. git checkout <mr.target>
2. git merge <mr.branch> --no-ff -m 'Merge <branch>: <title>'
3. If config.run_tests:
   - Run test_command (from config)
   - If failed: git reset --hard HEAD~1, return Failure(tests_failed)
4. git push origin <mr.target>
5. Return Success(merge_commit=HEAD)

Configuration:
- run_tests: bool (default true)
- test_command: string (default 'go test ./...')

Handle push failures with retry logic.

Reference: docs/merge-queue-design.md#process-merge-steps


Layered context onboarding pattern

Pattern from handoff discussion:

## Pattern: Layered Context Onboarding

Town CLAUDE.md (user/org) -> Rig CLAUDE.md (project) -> Role priming

## Ultra-compressed HOP for workers (no reveal)

- Permanent record: All work tracked. Outcomes matter.
- Quality gates: Molecule steps exist for a reason.
- Attribution: Completions build your track record.
- Handoff clean: Leave state any worker can continue.

## Recommendation

Create Town @AGENTS.md for shared worker context that all workers see.
This provides common behavioral guidance without revealing full HOP context.


Merge: gt-g44u.2

branch: polecat/Doof
target: main
source_issue: gt-g44u.2
rig: gastown


Heartbeat convention: simple liveness signal for agents

Lightweight liveness signal extracted from Deacon epic (gt-5af).

**Implementation**: Each agent writes a timestamp file on activity:
```bash
echo '{"ts":"'$(date -Iseconds)'"}' > ~/gt/<role>/heartbeat.json
```

**Integration points**:
- SessionStart hook writes heartbeat
- Periodic activity (mail check, work completion) refreshes it
- `gt status` shows staleness (e.g., 'mayor: 5m ago')

**Weight**: ~5 lines per agent
**Value**: Quick debugging - see which agents are active at a glance

No monitoring daemon needed - human checks `gt status` when curious.


Refinery background daemon mode

Refinery currently only works in foreground mode. Background daemon is stubbed.

## Current State
manager.go line 128-129:
```go
// Background mode: spawn a new process
// For MVP, we just mark as running - actual daemon implementation in gt-ov2
return nil
```

## Requirements

### 1. Background Process Spawning
```go
func (m *Manager) Start(foreground bool) error {
    if !foreground {
        // Spawn gt refinery start --foreground as subprocess
        cmd := exec.Command(os.Args[0], "refinery", "start", m.rig.Name, "--foreground")
        cmd.Start()  // Don't wait
        // Record PID
    }
}
```

### 2. PID File Management
- Write PID to .gastown/refinery.pid
- Check PID validity on status
- Clean up stale PID files

### 3. Log Output
- Redirect stdout/stderr to .gastown/refinery.log
- Log rotation (optional for MVP)

### 4. Graceful Shutdown
- Handle SIGTERM/SIGINT
- Complete current merge before exit
- Update state to stopped

### 5. Health Check
- Process existence check via kill -0
- Optional: heartbeat file with timestamp

## Files to Modify
- internal/refinery/manager.go: Start(), Status(), process spawning

## Acceptance Criteria
- [ ] gt refinery start <rig> spawns background process
- [ ] gt refinery status shows running with PID
- [ ] gt refinery stop sends SIGTERM and waits
- [ ] Logs written to .gastown/refinery.log
- [ ] Survives terminal close


Add crew lifecycle support to Deacon

Currently crew sessions (like gastown/crew/max, beads/crew/dave) are marked as 'human-managed' and excluded from automated lifecycle.

## Current State
- `getManager(RoleCrew)` returns `"human"` (handoff.go:273)
- `gt handoff` for crew just prints a message, no lifecycle request sent
- Crew cannot request automated refresh from Deacon

## Desired State
Crew members should be able to request lifecycle actions from Deacon:
- `gt handoff --cycle` sends request to Deacon, which kills/restarts the crew session
- Useful when: context full, running molecules that need fresh session, automation

## Implementation
1. Change `getManager(RoleCrew)` to return `"deacon/"` (or new crew manager)
2. Teach Deacon to recognize crew session naming pattern
3. Add crew to Deacon's respawn loop handling
4. Test with `gt nudge` for reliable message delivery

## Use Case
Running a molecule (e.g., version-bump) and discovering mid-workflow that a fresh session is needed. Agent should be able to request refresh automatically rather than requiring human intervention.

## Related
- gt nudge: reliable message delivery to Claude sessions
- bd mol bond: molecule instantiation (coming in beads)


Git wrapper: shell out to git

Wrapper for git operations via subprocess.

## Interface

```go
type Git struct {
    workDir string
}

func NewGit(workDir string) *Git

// Core operations
func (g *Git) Clone(url, dest string) error
func (g *Git) Checkout(ref string) error
func (g *Git) Fetch(remote string) error
func (g *Git) Pull(remote, branch string) error
func (g *Git) Push(remote, branch string, force bool) error

// Commit operations
func (g *Git) Add(paths ...string) error
func (g *Git) Commit(message string) error
func (g *Git) CommitAll(message string) error

// Query operations
func (g *Git) Status() (*GitStatus, error)
func (g *Git) CurrentBranch() (string, error)
func (g *Git) HasUncommittedChanges() (bool, error)
func (g *Git) RemoteURL(remote string) (string, error)

// Merge operations
func (g *Git) Merge(branch string) error
func (g *Git) Rebase(onto string) error
func (g *Git) AbortMerge() error
func (g *Git) AbortRebase() error
```

## Implementation

Shell out to git binary via exec.Command. Parse output where needed (Status, CurrentBranch).

## Error Handling

- Wrap git stderr in error messages
- Detect specific failures (merge conflict, auth failure, not a repo)
- Return structured errors for callers to handle

## Testing

- Use temp directories with real git repos
- Test both success and failure paths


CLI: worker status reporting commands

Worker status reporting CLI for polecats to report progress.

## Commands

### gt worker started
```
gt worker started <issue-id> [-m MESSAGE]
```
Reports work started on issue.

### gt worker progress
```
gt worker progress <issue-id> <0-100> [-m MESSAGE]
```
Reports percentage complete.

### gt worker blocked
```
gt worker blocked <issue-id> <reason> [-m MESSAGE]
```
Reports blocked status with reason.

### gt worker completed
```
gt worker completed <issue-id> [-m MESSAGE]
```
Reports task completion.

### gt worker failed
```
gt worker failed <issue-id> <reason> [-m MESSAGE]
```
Reports task failure.

## Implementation
Each command sends mail to refinery with structured content:
```go
type WorkerStatusReport struct {
    IssueID    string
    Status     string  // started|progress|blocked|completed|failed
    Progress   int     // 0-100 for progress
    Reason     string  // for blocked/failed
    Message    string  // optional detail
    ReportedAt time.Time
}
```

## Message Format
Subject: "[STATUS] <issue-id>: <status>"
Body: JSON-encoded WorkerStatusReport

## Default Recipient
```go
// Determine from context
func getDefaultRecipient() string {
    rig := os.Getenv("GT_RIG")
    if rig != "" {
        return rig + "/refinery"
    }
    return "refinery/"
}
```

## New File
internal/cmd/worker.go

## PGT Reference
gastown-py/src/gastown/cli/worker_cmd.py

## Acceptance Criteria
- [ ] All 5 commands implemented
- [ ] Status sent as mail to refinery
- [ ] Structured JSON body for parsing
- [ ] Works from polecat session context


gt mail read: Support numeric indices for message ID

Allow 'gt mail read 1' to read the first message in inbox.

Current behavior requires full message ID like 'msg-abc123'.
Should support:
- Numeric index: 'gt mail read 1' reads first/newest message
- Partial ID match: 'gt mail read abc' matches 'msg-abc123'

This is a UX improvement - agents frequently type 'gt mail read 1'.


HTTP work server: gt worker serve command

## Overview

HTTP server that runs inside Cloud Run containers, accepting work requests.

## Command

```bash
gt worker serve --port 8080
```

## Implementation

```go
type WorkServer struct {
    port    int
    handler *WorkHandler
}

func (s *WorkServer) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    switch r.URL.Path {
    case "/work":
        s.handleWork(w, r)
    case "/health":
        s.handleHealth(w, r)
    default:
        http.NotFound(w, r)
    }
}

func (s *WorkServer) handleWork(w http.ResponseWriter, r *http.Request) {
    // 1. Parse WorkRequest
    // 2. Clone/pull repo
    // 3. Start Claude on issue
    // 4. Stream WorkEvents as NDJSON
    // 5. Return WorkResult
}
```

## Streaming Response

```go
func (s *WorkServer) streamEvents(w http.ResponseWriter, events <-chan WorkEvent) {
    flusher, _ := w.(http.Flusher)
    encoder := json.NewEncoder(w)
    for event := range events {
        encoder.Encode(event)
        flusher.Flush()
    }
}
```

mol-polecat-work

Full polecat lifecycle from assignment to decommission.

This proto enables nondeterministic idempotence for polecat work.
A polecat that crashes after any step can restart, read its molecule state,
and continue from the last completed step. No work is lost.

Variables:
- gt-qwyu - The source issue ID being worked on


gt mail: Cross-level routing is broken

When Mayor sends mail to rig worker, message lands in wrong beads database. Sender's beads vs recipient's.


Consolidate design docs into beads descriptions

The markdown design docs (swarm-shutdown-design.md, polecat-beads-access-design.md, mayor-handoff-design.md) will decay. Extract key decisions and prompting templates into the beads descriptions themselves, then archive or remove the markdown files. Beads are the source of truth.


gt spawn --create should auto-add polecat if missing

## Problem

`gt spawn gastown --issue gt-xxx --create` fails if no polecats exist.

## Current Behavior

```
Error: auto-select polecat: no available polecats in rig 'gastown'
```

## Expected Behavior

`--create` should:
1. Create a new polecat if none exist
2. Or create the specified polecat if `gt spawn gastown/NewName --create`

## Workaround

Must manually run `gt polecat add gastown Name` first.

## Principle

Agent UX should be forgiving - if I say spawn with --create, make it work.


Merge: gt-5wb7

branch: polecat/nux
target: main
source_issue: gt-5wb7
rig: gastown


Create mol-gastown-polecat derived molecule

Create the standard Gas Town polecat workflow molecule.

## Molecule Definition
\`\`\`markdown
## Molecule: gastown-polecat
Full workflow for Gas Town polecats including binary installation.

Includes: mol-engineer-in-box

## Step: install-binary
After merge is submitted, rebuild and install the local gt binary.
This ensures the latest code is available to all local agents.

Run from the rig directory:
\`\`\`
go build -o gt ./cmd/gt
go install ./cmd/gt
\`\`\`

Needs: submit
\`\`\`

## Why This Molecule
Every polecat that pushes to main should also rebuild the binary.
This ensures the installed gt is always current with main.

## Implementation
1. Add to builtin_molecules.go (after Includes support lands)
2. Update SeedBuiltinMolecules
3. Run gt molecule seed

## Acceptance
- [ ] mol-gastown-polecat exists
- [ ] Includes all engineer-in-box steps
- [ ] Adds install-binary step after submit
- [ ] Can be used with gt spawn --molecule


LocalConnection: Local file/exec/tmux operations

LocalConnection implementation for local machine operations.

## Implementation

```go
type LocalConnection struct {
    tmux *Tmux
}

func NewLocalConnection() *LocalConnection

func (c *LocalConnection) Name() string { return "local" }
func (c *LocalConnection) IsLocal() bool { return true }
```

## File Operations

Direct passthrough to os package:
```go
func (c *LocalConnection) ReadFile(path string) ([]byte, error) {
    return os.ReadFile(path)
}
// etc.
```

## Command Execution

Uses exec.Command:
```go
func (c *LocalConnection) Exec(cmd string, args ...string) ([]byte, error) {
    return exec.Command(cmd, args...).Output()
}
```

## Tmux

Delegates to Tmux wrapper:
```go
func (c *LocalConnection) TmuxNewSession(name, dir string) error {
    return c.tmux.NewSession(name, dir)
}
```

## Notes

Straightforward implementation - this is the "baseline" connection that SSHConnection will mirror remotely.


Swarm learning: Witness needs automated context cycling

Furiosa hit 2% context during swarm work. Witness role needs automated detection of low context and should trigger session cycling before agents get stuck. Add to Witness responsibilities in prompts.md.


bd ready --type: missing type filter for MQ integration

bd ready lacks --type flag that engineer.go expects.

## Code (internal/refinery/engineer.go)
readyMRs, err := e.beads.ReadyWithType("merge-request")

## Actual bd ready
No --type flag - only supports assignee, label, priority filters.

## Impact
Refinery can't find merge-requests in queue, so MQ doesn't process anything.

## Fix Options
1. Add --type flag to bd ready
2. Use bd list --type=merge-request --status=open instead
3. Both (ready filters for unblocked, list for all)

This is blocking the entire MQ pipeline.

HTTP work client: CloudRun dispatch client

## Overview

HTTP client for dispatching work to Cloud Run and streaming results back.

## Implementation

```go
type WorkClient struct {
    serviceURL string
    httpClient *http.Client  // HTTP/2 enabled
}

func NewWorkClient(serviceURL string) *WorkClient {
    return &WorkClient{
        serviceURL: serviceURL,
        httpClient: &http.Client{
            Transport: &http2.Transport{},
            Timeout:   0,  // No timeout for streaming
        },
    }
}

func (c *WorkClient) DispatchWork(ctx context.Context, req WorkRequest) (<-chan WorkEvent, error) {
    // 1. POST to /work
    // 2. Return channel that streams WorkEvents
    // 3. Close channel when done/error
}
```

## Streaming Reader

```go
func (c *WorkClient) streamEvents(body io.Reader, events chan<- WorkEvent) {
    defer close(events)
    decoder := json.NewDecoder(body)
    for {
        var event WorkEvent
        if err := decoder.Decode(&event); err != nil {
            return
        }
        events <- event
    }
}

Test message

Testing GGT mail integration


Add --fart as easter egg alias for bd mol bond

Add a hidden alias for the bond command:

```bash
bd mol fart mol-polecat-work --wisp
# equivalent to:
bd mol bond mol-polecat-work --wisp
```

## Context
The fart joke: instantiating a proto can produce either:
- A Mol (solid/substantial output)
- A Wisp (gas/ephemeral output)

## Implementation
- Add 'fart' as an alias in the mol subcommand
- No documentation needed (easter egg)
- Maybe a fun message: 'Bonding molecule...' or similar

Low priority, just for fun.


gt install command: Create workspace structure

Create Gas Town workspace structure.

## Command

```
gt install [path]
```

If path omitted, uses current directory.

## Created Structure

```
<path>/
├── config/
│   ├── town.json      # {"type": "town", "version": 1, ...}
│   └── rigs.json      # {"version": 1, "rigs": {}}
│
└── mayor/
    ├── CLAUDE.md      # Mayor role prompting (from template)
    ├── mail/
    │   └── inbox.jsonl  # Empty inbox
    └── state.json     # Initial mayor state
```

## Implementation

```go
func Install(path string, opts InstallOptions) error

type InstallOptions struct {
    TownName string  // defaults to directory name
    Force    bool    // overwrite existing
}
```

## Steps

1. Validate path (exists, writable)
2. Check not already a town (unless --force)
3. Create config/ directory
4. Write town.json with name and timestamp
5. Write empty rigs.json
6. Create mayor/ directory structure
7. Write CLAUDE.md from template
8. Create empty inbox.jsonl
9. Write initial state.json

## Error Cases

- Path does not exist: Create it (like mkdir -p)
- Already a town: Error unless --force
- Permission denied: Clear error message
- Inside existing town: Warn (nested towns not recommended)

## Templates

Mayor CLAUDE.md comes from embedded template (see gt-u1j.20).


gt witness: Witness management commands

Add 'gt witness' command group for witness lifecycle management.

Subcommands:
- gt witness start [rig] - Start witness for a rig
- gt witness stop [rig] - Stop witness
- gt witness status [rig] - Show witness status
- gt witness attach [rig] - Attach to witness session

Witness monitors polecats and handles:
- Idle detection and cleanup
- Session health checks
- Nudging stuck agents


gt doctor: Detect and clean up orphaned sessions/processes

## Problem
Orphaned tmux sessions and Claude processes accumulate over time, consuming memory.

## Discovered Orphans
- gt-deacon: Idle Claude session, not part of any rig

## Proposed Solution

### gt doctor --check (default)
Detect issues without fixing:
- Orphan sessions (not matching rig/polecat/crew/witness/refinery/mayor pattern)
- Claude processes without parent tmux session
- Tmux sessions without Claude (stuck at bash prompt)
- Polecats marked 'working' but session idle

### gt doctor --fix
Clean up detected issues:
- Kill orphan sessions
- Kill orphan Claude processes
- Optionally reset stuck polecat state

### gt gc (alternative name)
Short alias for cleanup operations.

## Acceptance Criteria
- [ ] Detects orphan sessions
- [ ] Detects orphan processes
- [ ] Safe cleanup (doesn't kill active work)
- [ ] Reports what was cleaned

Immediate daemon notification on lifecycle request

When gt handoff sends a lifecycle request to the daemon (via bd mail send deacon/), the daemon only discovers it on its next heartbeat poll (every 5 min). Workers wait unnecessarily for retirement.

## Current Behavior
1. Worker runs gt handoff
2. Lifecycle mail sent to deacon/ via beads
3. Worker blocks waiting for retirement
4. Daemon heartbeat runs (up to 5 min later)
5. Daemon processes lifecycle request and kills session

## Expected Behavior
Lifecycle requests should be processed immediately, not on poll interval.

## Proposed Solutions

### Option A: SIGUSR1 Signal (simplest)
1. Add SIGUSR1 handler in daemon that calls ProcessLifecycleRequests()
2. gt handoff reads daemon.pid and sends SIGUSR1 after mail send

### Option B: Unix Socket
1. Daemon listens on ~/gt/daemon/lifecycle.sock
2. gt handoff connects and sends 'process' message

### Option C: Watchfile + fsnotify
1. gt handoff touches ~/gt/daemon/lifecycle.trigger
2. Daemon uses fsnotify to detect and process

Recommend Option A for simplicity.

## Affected Files
- internal/daemon/daemon.go - add signal handler
- internal/cmd/handoff.go - send signal after mail

Witness session startup (gt witness start)

Implement gt witness start <rig>

Should:
1. Verify rig exists and has witness/ directory
2. Check for existing witness session (don't double-start)
3. Create tmux session: gt-<rig>-witness
4. Start Claude Code with --dangerously-skip-permissions
5. Send gt prime to load context
6. Send startup prompt

Similar pattern to refinery startup in internal/refinery/manager.go


Connection interface: Protocol for local/remote ops

Abstract interface for local vs remote (SSH) operations.

## Concept

Enable Gas Town to manage rigs on remote machines via SSH. The Connection interface abstracts whether operations happen locally or remotely.

## Interface

```go
type Connection interface {
    // Identification
    Name() string
    IsLocal() bool

    // File operations
    ReadFile(path string) ([]byte, error)
    WriteFile(path string, data []byte, perm os.FileMode) error
    MkdirAll(path string, perm os.FileMode) error
    Remove(path string) error
    Stat(path string) (os.FileInfo, error)
    Glob(pattern string) ([]string, error)

    // Command execution
    Exec(cmd string, args ...string) ([]byte, error)
    ExecDir(dir, cmd string, args ...string) ([]byte, error)

    // Tmux (for session management)
    TmuxNewSession(name, dir string) error
    TmuxKillSession(name string) error
    TmuxSendKeys(session, keys string) error
    TmuxCapturePane(session string, lines int) (string, error)
}
```

## Implementations

- LocalConnection (gt-f9x.8): Direct file/exec operations
- SSHConnection (future): Operations via SSH

## Usage

```go
func NewRigManager(conn Connection, ...) *RigManager

// Operations work the same regardless of connection type
rm.DiscoverRigs()  // uses conn.Glob, conn.ReadFile
```

## Design Notes

- Connection obtained from MachineRegistry (gt-f9x.9)
- Default is always local
- SSH connection requires machine config (host, key, user)


gt mq integration status: show integration branch status

Implement 'gt mq integration status <epic>' command.

Display:
- Integration branch name and creation date
- Commits ahead of main
- MRs merged to integration (closed)
- MRs pending (open, targeting integration)
- Comparison: main..integration/<epic>

Output example:
  Integration: integration/gt-auth-epic
  Created: 2025-12-17
  Ahead of main: 5 commits

  Merged MRs (3):
    gt-mr-001  Fix login timeout
    gt-mr-002  Fix session expiry
    gt-mr-003  Update auth config

  Pending MRs (1):
    gt-mr-004  Update auth tests (in_progress)

Use cmd.OutOrStdout instead of fmt.Print in refinery

refinery/manager.go and refinery/engineer.go use fmt.Print/Println directly for user output (30+ occurrences). This breaks testability and doesn't follow cobra best practices. Should use cmd.OutOrStdout() or pass an io.Writer.

Affected files:
- internal/refinery/manager.go (lines 222, 360-361, 369, 387-393, 519, 537, 672)
- internal/refinery/engineer.go (lines 190-211, 249, 294-297, 325-353, 362-366)


Document the Propulsion Principle

Write canonical documentation for the Universal Gas Town Propulsion Principle.

Location: gastown/mayor/rig/docs/propulsion-principle.md

Content:
- The One Rule (hook has work → work happens)
- Why it works (stateless agents, molecule-driven)
- The sling lifecycle diagram
- Agent startup protocol
- Examples and anti-patterns

This is foundational theory-of-operation documentation.


Crew worker CLAUDE.md prompting

Create CLAUDE.md template for crew workers:
- Explain crew worker role (overseer's personal workspace)
- Include mail-to-self handoff instructions
- Document gt crew refresh for context cycling
- Explain no witness monitoring (user-managed)
- Include beads usage if BEADS_DIR configured


CloudRun worker container: Dockerfile and entrypoint

## Overview

Docker container image for Cloud Run workers.

## Dockerfile

```dockerfile
FROM golang:1.21-alpine AS builder
WORKDIR /app
COPY . .
RUN go build -o gt ./cmd/gt

FROM ubuntu:22.04

# Install Claude Code

Plugin system: subprocess JSON protocol

Language-agnostic plugin system via subprocess JSON protocol.

## Concept

Allow extending Gas Town with external scripts/programs. Plugins communicate via stdin/stdout JSON.

## Protocol

Request (gt → plugin):
```json
{"method": "check", "params": {"rig": "wyvern", "polecat": "Toast"}}
```

Response (plugin → gt):
```json
{"result": {...}, "error": null}
```

Error response:
```json
{"result": null, "error": {"code": 1, "message": "..."}}
```

## Interface

```go
type Plugin struct {
    Name    string
    Path    string  // executable path
    Methods []string
}

type PluginManager struct {
    plugins map[string]*Plugin
}

func NewPluginManager() *PluginManager
func (pm *PluginManager) Register(plugin *Plugin) error
func (pm *PluginManager) Call(plugin, method string, params any) (any, error)
func (pm *PluginManager) Discover(dir string) error  // auto-discover plugins
```

## Plugin Discovery

Look in:
1. `<town>/plugins/`
2. `~/.config/gastown/plugins/`
3. System path with `gt-plugin-*` prefix

## Built-in Hooks

Plugins can register for events:
- `polecat.started` - Polecat session started
- `polecat.done` - Polecat signals done
- `merge.requested` - MR submitted
- `merge.completed` - MR merged

## Use Cases

- Custom health checks
- Integration with external systems (Slack, etc.)
- Custom merge policies
- Metrics collection

## Future

Consider MCP integration for richer plugin capabilities.


Define Engineer as the Refinery agent role

Clarify the distinction:

- **Refinery** = place/module/directory/workspace
  - `<rig>/refinery/` directory structure
  - `gt refinery start/stop/status` commands
  - tmux session name: `refinery` or `<rig>-refinery`

- **Engineer** = role/agent who works in the Refinery
  - CLAUDE.md prompting: "You are an Engineer..."
  - Documentation: "The Engineer processes merge requests..."
  - Mail address: `<rig>/engineer` (or `<rig>/refinery`?)

Updates needed:
- Add Engineer role description to docs
- Update CLAUDE.md templates for refinery agents
- Keep `gt refinery` commands as-is (they manage the place)
- Internal code stays `internal/refinery/` (the module)

Future consideration: Multiple Engineers in one Refinery for parallel merge processing.


Add mayor/config.json for town-level configuration

Create new town-level config file:
- Add TownConfig.Config field to types.go
- Create mayor/config.json with theme defaults, daemon settings
- Update loader to read/write mayor/config.json
- Migrate any town-level config from .gastown/ to here


Phase 4.1: mol-deacon-patrol uses ephemeral

Deacon patrol cycles run as ephemeral molecules.

## Current Deacon Loop

```
while running:
    check_heartbeat()
    check_mail()
    sleep(interval)
```

## Molecule-Based Loop

```
while running:
    mol = bd mol bond mol-deacon-patrol-cycle --ephemeral
    execute_cycle(mol):
        check_heartbeat()
        check_mail()
        log_status()
    summary = generate_cycle_summary()
    bd squash mol --summary summary
    sleep(interval)
```

## Benefits

- Each cycle is tracked
- Digests show daemon health over time
- Can query: 'show me patrol cycles from last hour'
- Crash mid-cycle → ephemeral shows where we were


plugin-run

Execute plugins from ~/gt/plugins/. Check gates, run eligible plugins.


Merge: gt-xw7b

branch: polecat/morsov
target: main
source_issue: gt-xw7b
rig: gastown


gt done: Missing command referenced in polecat docs


Create rig .runtime/ for rig runtime state

Move ephemeral rig state to .runtime/:
- Create <rig>/.runtime/ directory
- Move .gastown/witness.json → .runtime/witness.json
- Move .gastown/refinery.json → .runtime/refinery.json
- Move .gastown/namepool.json (state portion) → .runtime/namepool-state.json
- Update .gitignore to ignore .runtime/
- Update all code references


Add no-PR instructions to mol-polecat-work at two points

Update mol-polecat-work in builtin_molecules.go to explicitly forbid GitHub PRs.

## Two Points to Add Instructions

### 1. submit-work step
When polecat is ready to submit:
- Push branch to origin
- Create beads merge-request issue
- DO NOT use gh pr create or GitHub PRs

### 2. CLAUDE.md polecat context
Add to polecat role instructions:
- Never use gh pr create
- Never create GitHub pull requests
- The Refinery processes merges via beads MR issues

## Why Two Points
- Molecule step description guides the workflow
- CLAUDE.md reinforces at context level
- Belt and suspenders approach

## Implementation
1. Update PolecatWorkMolecule() submit-work step description
2. Update prompts/roles/polecat.md with explicit prohibition

gt refinery start: doesn't actually start a session

## Problem

`gt refinery start gastown` reports success but doesn't start a tmux session.

## Evidence

```
$ gt refinery start gastown
Starting refinery for gastown...
✓ Refinery started for gastown

$ tmux list-sessions | grep refinery
(nothing)

$ gt refinery status gastown
State: ○ stopped
```

## Expected

Should start a tmux session (e.g., gt-gastown-refinery) with Claude processing the merge queue.

## Related

- gt-kcee: Witness commands also need implementation
- The refinery 'start' may just be updating state.json without spawning a session


Fix blocking bugs (gt-dsfi, gt-n7z7, gm-c6b)

Fix bugs blocking Witness functionality:

1. gt-dsfi: handoff deadlock
   - Polecats hang when trying to exit
   - Blocks shutdown request handler

2. gt-n7z7: refinery foreground race condition
   - Sometimes detects parent as already running
   - Blocks reliable Refinery startup

3. gm-c6b: mail coordination
   - Cross-rig mail should use town-level database
   - Affects Witness <-> Mayor communication

These should be fixed early as they'll block integration testing.

Fixed gt-dsfi and gt-n7z7. Issue gm-c6b not found in database.

Outpost assignment policy: Smart work routing

## Overview

Policy engine for deciding which outpost gets which work.

## Policy Configuration

```yaml
policy:
  # Default order of preference
  default_preference: [local, gce-burst, cloudrun-burst]

  # Rules applied in order
  rules:
    # Background work → Cloud Run (cheap)
    - condition: "priority >= P3"
      prefer: cloudrun-burst

    # Long tasks → VM (persistent)
    - condition: "estimated_duration > 30m"
      prefer: gce-burst

    # Specific epic → specific outpost
    - condition: "epic == gt-abc"
      prefer: local
```

## Implementation

```go
type AssignmentPolicy struct {
    DefaultPreference []string
    Rules             []PolicyRule
}

type PolicyRule struct {
    Condition string   // Simple expression
    Prefer    string   // Outpost name
    Require   string   // Must use this outpost
}

func (p *AssignmentPolicy) SelectOutpost(
    issue Issue,
    outposts map[string]Outpost,
) Outpost {
    // Check rules in order
    for _, rule := range p.Rules {
        if rule.Matches(issue) {
            if op, ok := outposts[rule.Prefer]; ok {
                if op.ActiveWorkers() < op.MaxWorkers() {
                    return op
                }
            }
        }
    }

    // Fall back to default preference
    for _, name := range p.DefaultPreference {
        if op, ok := outposts[name]; ok {
            if op.ActiveWorkers() < op.MaxWorkers() {
                return op
            }
        }
    }

    return nil  // All outposts at capacity
}
```

## Condition Language

Simple expressions, not a full DSL:

```
priority >= P3
priority == P0
estimated_duration > 30m
epic == gt-abc
type == bug
label contains "urgent"
```

Test Task 1: Add comment to gt.go


Post-work discovery: AI analysis finds follow-on issues

AI analyzes completed work to discover: bugs, punted work, follow-on tasks.

**From VC**: Supervisor.AnalyzeResult() with iterative refinement. ~300 lines.

**Gas Town implementation**: Post-work hook in molecule:
```yaml
post_work:
  discover:
    - bugs
    - punted_items
    - follow_on_work
  file_as: beads
```

Polecat output gets analyzed by AI, discovered work becomes beads issues.

**Value**: Nothing gets forgotten. VC found ~25% more issues with refinement.

**Key**: Use semantic deduplication (gt-xxx) to avoid pollution.


Daemon heartbeat: worker and queue monitoring

Daemon periodic checks for work progress.

## Heartbeat Actions

Every N seconds (configurable):

1. Check Witness health per rig
   - Poke if witness needs to nudge workers

2. Check Refinery queue per rig
   - Poke if pending work in queue

3. Check work completion
   - If epic children all closed, notify Mayor

## Eventually Convergent

Multiple signals reinforce state:
- Polecat signals done → Witness notices → pokes Refinery
- Daemon heartbeat → checks queue → pokes Refinery
- Beads status → queryable by any agent

Even if one signal missed, system converges.

## Interface

```go
func (d *Daemon) HeartbeatLoop() {
    for {
        for _, rig := range d.rigs {
            d.CheckWitness(rig)
            d.CheckRefinery(rig)
            d.CheckWorkProgress(rig)
        }
        time.Sleep(d.config.HeartbeatInterval)
    }
}
```

## Notifications

Use mail with low priority for heartbeat pokes.
Agents can ignore if already processing.


Crew directory structure and config

Add crew/ directory support to rig structure. Include:
- crew/ as peer to polecats/, refinery/, witness/
- Crew worker subdirectories with full git clones
- Optional BEADS_DIR configuration for beads integration
- Crew state tracking (separate from polecat state)


Witness pre-kill verification protocol

Add pre-kill verification protocol to Witness CLAUDE.md template.

## Protocol for Witness Prompting

```markdown
## Pre-Kill Verification Protocol

Before killing any worker session, verify workspace is clean.

### Verification Steps

When a worker signals done:

1. **Capture worker state**:
```bash
town capture <polecat> "git status && git stash list && bd sync --status"
```

2. **Assess the output** (use your judgment):
- Is working tree clean?
- Is stash list empty?
- Is beads synced?

3. **Decision**:
- **CLEAN**: Proceed to kill session
- **DIRTY**: Send nudge with specific issues

### Nudge Templates

**Uncommitted Changes**:
```
town inject <polecat> "WITNESS CHECK: Uncommitted changes found. Please commit or discard: <files>. Signal done when clean."
```

**Beads Not Synced**:
```
town inject <polecat> "WITNESS CHECK: Beads not synced. Run 'bd sync' then commit. Signal done when complete."
```

### Kill Sequence

Only after verification passes:
```bash
town kill <polecat>
town sleep <polecat>
```

### Escalation

If worker fails verification 3+ times:
```bash
town mail send mayor/ -s "Escalation: <polecat> stuck" -m "Cannot complete cleanup after 3 attempts. Issues: <list>."
```
```

## Implementation

Add to WITNESS_CLAUDE.md template.


Document Overseer role (human operator)

Document the Overseer role in Gas Town architecture.

## The Overseer

The **Overseer** is the human operator of Gas Town. Not an agent - a person.

## Responsibilities

| Area | Overseer Does | Mayor/Agents Do |
|------|---------------|-----------------|
| Strategy | Define project goals | Execute toward goals |
| Priorities | Set priority order | Work in priority order |
| Escalations | Final decision on stuck work | Escalate to Overseer |
| Resources | Provision machines | Use allocated resources |
| Quality | Review & approve swarm output | Produce output |
| Operations | Run gt commands, monitor dashboards | Do the work |

## Key Interactions

### Overseer → Mayor
- Start/stop Mayor sessions
- Direct Mayor via conversation
- Review Mayor recommendations
- Approve cross-rig decisions

### Mayor → Overseer (Escalations)
- Stuck workers after retries
- Resource decisions (add machines, polecats)
- Ambiguous requirements
- Architecture decisions

## Operating Cadence

Typical Overseer workflow:
1. Morning: Check status, review overnight work
2. During day: Monitor, respond to escalations, adjust priorities
3. End of day: Review progress, plan next batch

## Commands for Overseers

```bash
gt status              # Quick health check
gt doctor              # Detailed diagnostics
gt doctor --fix        # Auto-repair issues
gt inbox               # Messages from agents
gt stop --all          # Emergency halt
```

## Documentation Updates

Add to docs/architecture.md:
- Overseer section under Agent Roles
- Clarify Mayor reports to Overseer
- Add Overseer to workflow diagrams


Design GGT prompt architecture

Audit PGT prompts and design canonical prompt system for GGT. Create docs/prompts.md with inventory, gap analysis, and Witness prompt design.


Update harness beads redirect for GGT

Change ~/ai/.beads/redirect from mayor/rigs/gastown/.beads to gastown/mayor/.beads for the GGT directory structure


Add agent abstraction layer to support non-Claude agents

Currently Gas Town hardcodes 'claude --dangerously-skip-permissions' throughout the codebase for spawning agents. We should add an abstraction layer to support other AI agents (e.g., Gemini CLI, OpenAI agents, local models).

Locations that spawn Claude:
- internal/cmd/mayor.go:131
- internal/cmd/deacon.go:150
- internal/cmd/witness.go:280
- internal/cmd/crew.go (multiple locations)
- internal/cmd/up.go:190, 229
- internal/session/manager.go:146
- internal/refinery/manager.go:207

Suggested approach:
1. Create an agent package with an interface
2. Add configuration for agent type in town/rig config
3. Replace hardcoded claude commands with agent.Spawn() calls
4. Support agents: claude, gemini, openai, local (ollama, etc.)


Phase 3.2: mol-polecat-work squash step

Add summary+squash as final steps in mol-polecat-work.

## Current Steps

1. read-assignment
2. understand-task
3. implement-solution
4. verify-tests
5. commit-work
6. signal-done

## Updated Steps

1. read-assignment
2. understand-task
3. implement-solution
4. verify-tests
5. commit-work
6. **generate-summary** ← NEW
7. **squash-molecule** ← NEW
8. signal-done

## Step Definitions

### generate-summary
Agent writes a concise summary following the template.
Save to a local variable or temp file.

### squash-molecule
Run: bd squash $MOLECULE_ROOT --summary "$SUMMARY"
This creates digest in main beads, cleans ephemeral.

## Update Location

This requires updating the mol-polecat-work definition in beads molecule catalog.


Test: release command verification


Mayor handoff mail template

Add MAYOR_HANDOFF mail template to templates.py.

## Template Function

def mayor_handoff(
    active_swarms: List[SwarmStatus],
    rig_status: Dict[str, RigStatus],
    pending_escalations: List[Escalation],
    in_flight_decisions: List[Decision],
    recent_actions: List[str],
    delegated_work: List[DelegatedItem],
    user_requests: List[str],
    next_steps: List[str],
    warnings: Optional[str] = None,
    session_duration: Optional[str] = None,
) -> Message:
    metadata = {
        'template': 'MAYOR_HANDOFF',
        'timestamp': datetime.utcnow().isoformat(),
        'session_duration': session_duration,
        'active_swarm_count': len(active_swarms),
        'pending_escalation_count': len(pending_escalations),
    }
    # ... format sections ...
    return Message.create(
        sender='mayor/',
        recipient='mayor/',
        subject='Session Handoff',
        body=body,
        priority='high',
    )

## Metadata Fields

- template: MAYOR_HANDOFF
- timestamp: ISO format
- session_duration: Human readable
- active_swarm_count: Number of active swarms
- pending_escalation_count: Number of escalations

## Mail Priority

Use priority='high' to ensure handoff is seen on startup.


Batch Work System: Integration branch, merge queue, landing

## Overview

This epic tracks batch work coordination in GGT. Key insight: **work is a stream, not discrete swarms**.

There are no "swarm IDs" - the epic IS the grouping, the merge queue IS the coordination. "Swarming an epic" is colloquial for spawning multiple workers on its children.

## Architecture

- **Epics** group related work
- **Issues** are individual tasks
- **Dependencies** encode ordering (multi-wave emerges automatically)
- **Merge queue** coordinates completed work
- **Workers** process issues independently

See Key Decision #11 in docs/architecture.md: "Work is a Stream (No Swarm IDs)"

## What This Epic Covers

1. Integration branch management for batch merges
2. Refinery semantic merge processing
3. Witness landing protocol (cleanup)
4. Report generation (epic-based, not swarm-ID-based)
5. Git safety auditing
6. Work reconciliation

## What Was Removed

- Swarm IDs (sw-1, sw-2, etc.)
- Per-swarm directories (.gastown/swarms/<id>/)
- Swarm manifest/state/events files
- swarm-started/swarm-landed beads

These were redundant - beads already provides hierarchy, status, dependencies, and history.

## References

- Architecture: docs/architecture.md (Key Decision #11, Multi-Wave Work Processing)
- PGT: swarm/manager.py, swarm/landing.py (behavioral reference, but ignore swarm ID patterns)


CLI: names commands for polecat naming pool

Polecat naming pool for auto-generated names.

## Commands

### gt names generate
```
gt names generate [--count N]
```
Generate N names from pool.

### gt names add
```
gt names add <name>...
```
Add custom names to pool.

### gt names list
```
gt names list
```
Show available and used names.

### gt names reset
```
gt names reset [--keep-used]
```
Reset pool to defaults.

## Config File
<rig>/town/naming.json:
```json
{
  "enabled": true,
  "auto_refill": true,
  "refill_threshold": 5,
  "pool": {
    "available": ["Toast", "Nux", "Capable", ...],
    "used": ["Alice", "Bob"]
  }
}
```

## Default Pool
Mad Max themed: Toast, Nux, Capable, Furiosa, Immortan, etc.

## Integration
gt polecat add calls naming pool if no name given:
```go
if name == "" {
    name, err = naming.Generate(rigPath)
}
```

## New Package
internal/naming/
├── pool.go     # Pool management
└── defaults.go # Default name lists

## Acceptance Criteria
- [ ] Auto-generate names on polecat add
- [ ] Track used vs available
- [ ] Auto-refill when low
- [ ] Custom names addable


session-gc

Clean dead sessions. Run gt gc --sessions.


Bug: refinery --foreground detects parent session as already running

When gt refinery start gastown runs:
1. Creates tmux session gt-gastown-refinery
2. Sends 'gt refinery start gastown --foreground' into the session
3. The foreground command checks HasSession() - finds the session it's inside
4. Returns 'already running' error

The foreground mode check should either:
- Skip the tmux session check (only check PID)
- Use a different indicator that the daemon loop is running
- Pass a flag to indicate we're being called from the background starter

Workaround: Manually run 'gt refinery start gastown --foreground' from a fresh session.


Overseer Crew: User-managed persistent workspaces

## Overview

Crew workers are the overseer's (human's) personal workspaces within a rig. Unlike polecats which are witness-managed and ephemeral, crew workers are:

- **Persistent**: Not auto-garbage-collected
- **User-managed**: Overseer controls lifecycle
- **Long-lived identities**: dave, emma, fred - recognizable names
- **Gas Town integrated**: Mail, handoff mechanics work
- **Tmux optional**: Can work in terminal directly

## Directory Structure

```
<rig>/
  polecats/       # Managed workers (witness controls)
  refinery/       # Merge queue processor
  witness/        # Pit boss
  crew/           # Overseer's personal workspaces
    dave/         # Full clone, persistent
    emma/         # Full clone, persistent
    fred/         # Full clone, persistent
```

## Key Differences from Polecats

- Location: crew/ instead of polecats/
- Lifecycle: User-managed, not witness-managed
- Auto-cleanup: Never (polecats auto-cleanup on swarm land)
- Issue assignment: Optional (polecats require it)
- Tmux: Optional (polecats require it)
- Mail & Handoff: Yes for both
- Identity: Persistent (polecats are ephemeral)

## CLI Commands

- gt crew add <name> [--rig <rig>] - Create crew workspace
- gt crew list [--rig <rig>] - List crew workspaces
- gt crew at <rig>/<name> - Attach to workspace (start session)
- gt crew attach <name> - Attach (infer rig from cwd)
- gt crew refresh <name> - Handoff + restart (context cycling)
- gt crew remove <name> [--force] - Remove workspace
- gt crew status [<name>] - Show workspace status

## Design Notes

- Crew workers use full git clones (not worktrees)
- Optional beads integration via BEADS_DIR
- Mail-to-self handoff works for context cycling
- No witness monitoring or nudging
- No automatic issue assignment required

## Background

Users often maintain separate repo clones for serial agent work. This is tedious to set up manually. Crew workspaces bring these into Gas Town's infrastructure while keeping user control.


MR field parsing: extract structured fields from description

Parse merge-request beads to extract structured fields:
- branch: source branch name
- target: target branch (main or integration/xxx)
- source_issue: the work item being merged
- worker: who did the work
- rig: which rig
- merge_commit: (set on close)
- close_reason: (set on close)

Fields stored in description as YAML block or key: value lines.
Provide helper functions: ParseMRFields(issue) and SetMRFields(issue, fields).

Define the Deacon patrol molecule in builtin_molecules.go.

## Steps
1. inbox-check - Handle callbacks from agents
2. health-scan - Ping Witnesses and Refineries
3. plugin-run - Execute registered plugins
4. orphan-check - Find abandoned work
5. session-gc - Clean dead sessions
6. context-check - Check own context limit
7. loop-or-exit - Burn and let daemon respawn, or exit if context high

## Implementation
- Add DeaconPatrolMolecule() to builtin_molecules.go
- Add to BuiltinMolecules() list
- Test with bd mol show mol-deacon-patrol


gt swarm: Not discovering tasks from epic dependents

gt swarm create/start shows '0 tasks loaded' even when epic has dependents.

Repro:
1. Create epic gt-hw6
2. Create tasks and add deps: bd dep add gt-xxx gt-hw6
3. gt swarm create gastown --epic gt-hw6 --worker Toast
4. Swarm shows 'Tasks: 0'

Expected: Swarm should discover tasks that depend on the epic.
Actual: Shows '(no tasks loaded)'


Phase 1.2: Configure bd for ephemeral molecule bonding

Ensure bd mol bond --ephemeral works with Gas Town setup.

## Questions for Dave

1. Does bd automatically find .beads-ephemeral/ or need explicit path?
2. How does bd mol bond --ephemeral know which repo to use?
3. Is there a redirect mechanism for ephemeral like main beads?

## Integration

From polecat/crew working directory:
```bash
bd mol bond mol-polecat-work --ephemeral --assignee $(gt whoami)
```

Should create molecule in rig's .beads-ephemeral/, not main beads.


gt polecat: add 'done' or 'finish' command to transition from working to idle

When a polecat finishes work but session wasn't properly cleaned up, there's no way to reset it from 'working' state back to 'idle'.

Tried:
```
gt polecat sleep gastown/Angharad
Error: sleeping polecat: polecat is not active (state: working)
```

The sleep command only works on 'active' polecats, not 'working' ones.

Had to manually edit state.json to reset:
```
jq '.state = "idle" | .issue = ""' state.json
```

Need a command like:
```
gt polecat done gastown/Angharad   # working -> idle
gt polecat finish gastown/Angharad # working -> idle
gt polecat reset gastown/Angharad  # any state -> idle (force)
```


submit-merge

Submit to merge queue. Create branch if needed.

Work on ga-ct2: Add MR workflow to polecat completion. When polecat completes work, auto-create MR to integration branch. When done, submit MR (not PR) to integration branch for Refinery.


Architecture: Decentralized rig structure with per-rig agents

## Decision

Adopt decentralized architecture where each rig contains all its agents (mayor/, witness/, refinery/, polecats/) rather than centralizing mayor clones at town level.

## Town Level Structure

```
~/ai/                              # Town root
├── config/                        # Town config (VISIBLE, not hidden)
│   ├── town.json                  # {"type": "town"}
│   ├── rigs.json                  # Registry of managed rigs
│   └── federation.json            # Wasteland config (future)
│
├── mayor/                         # Mayor's HOME at town level
│   ├── CLAUDE.md
│   ├── mail/inbox.jsonl
│   └── state.json
│
└── <rigs>/                        # Managed projects
```

## Rig Level Structure (e.g., wyvern)

```
wyvern/                            # Rig = clone of project repo
├── .git/info/exclude              # Gas Town adds: polecats/ refinery/ witness/ mayor/
├── .beads/                        # Beads (if project uses it)
├── [project files]                # Clean project code on main
│
├── polecats/                      # Worker clones
│   └── <name>/                    # Each is a git clone
│
├── refinery/
│   ├── rig/                       # Refinery's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
├── witness/                       # NEW: Per-rig pit boss
│   ├── rig/                       # Witness's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
└── mayor/
    ├── rig/                       # Mayor's clone for this rig
    └── state.json
```

## Key Decisions

1. **Visible config dir**: `config/` not `.gastown/` (models don't find hidden dirs)
2. **Witness per-rig**: Each rig has its own Witness (pit boss) with its own clone
3. **Mayor decentralized**: Mayor's clones live IN each rig at `<rig>/mayor/rig/`
4. **Minimal invasiveness**: Only `.git/info/exclude` modified, no commits to project
5. **Clone subdir name**: Keep `rig/` for consistency (refinery/rig/, witness/rig/, mayor/rig/)

## Role Detection

- Town root or mayor/ → Mayor (town level)
- Rig root → Mayor (canonical main)
- <rig>/mayor/rig/ → Mayor (rig-specific)
- <rig>/refinery/rig/ → Refinery
- <rig>/witness/rig/ → Witness
- <rig>/polecats/<name>/ → Polecat

## Migration from PGT

- `mayor/rigs/<rig>/` → `<rig>/mayor/rig/`
- `<rig>/town/` → eliminated (rig root IS the clone)
- Add `witness/` to each rig

Testing gt mail


Phase 2.3: Polecat CLAUDE.md molecule workflow protocol

Update polecat prompting for molecule-based work.

## CLAUDE.md Updates

Add section on molecule workflow:

```markdown
## Molecule Workflow

When assigned a molecule (check gt prime output):

1. Follow molecule steps in order
2. Mark steps complete: bd mol step complete <step-id>
3. Before signaling done:
   a. Generate summary of work performed
   b. Run: bd squash <molecule-root> --summary "<your summary>"
4. Then signal done as normal

### Summary Guidelines

Your summary should include:
- What was the task?
- What did you do?
- What was the outcome?
- Any issues or follow-ups?

Keep it to 2-4 sentences. This becomes the permanent record.
```


Refinery Engineer: Role prompting and CLAUDE.md

Create refinery/CLAUDE.md with Chief Merge Engineer role context. Include:
- Role identity and responsibilities
- Decision authority (merge order, test frequency, binary rebuilds)
- Communication patterns (Witness, Deacon)
- Session lifecycle (handoff bead protocol)
- Key commands reference


Bug: LIFECYCLE messages use literal <rig> placeholder

Found stale LIFECYCLE messages addressed to @<rig>/witness instead of actual rig names like @gastown/witness. Template substitution not happening.

Examples found:
- gm-bay: LIFECYCLE: polecat requesting shutdown (to @<rig>/witness)
- gm-7du, gm-94e, gm-u5x, gm-89b: same issue

Fix: Ensure rig name is substituted in lifecycle mail templates.


gt rig info: Show detailed rig information

Add 'gt rig info <rig>' command to show detailed rig status.

Should show:
- Rig path and git URL
- Active polecats with status
- Refinery status
- Witness status
- Recent activity
- Beads summary (open issues count)


gt orphans: Find lost polecat work

Add a command to find orphaned commits that were never merged to main.

## Problem
Polecat work can get lost when:
- Session killed before merge
- Refinery fails to process
- Network issues during push

## Solution
Add `gt orphans` command that:
1. Uses `git fsck --unreachable` to find dangling commits
2. Filters to recent commits (default: 7 days, configurable)
3. Excludes stash/index entries (WIP on, index on)
4. Shows commit details and suggests recovery

## Usage
```
gt orphans              # Last 7 days
gt orphans --days=14    # Last 2 weeks
gt orphans --recover    # Interactive cherry-pick
```

## Found orphans (Dec 16-20, 2025)
- 3b146c11: Fix mail read auto-ack and add Mayor startup directive
- b6fdc561: Add persistent theme config and fix crew session theming
- 97aba756: Unify gt prime to call bd prime and mail check
- ce769ca5: Add mol-bootstrap molecule for Gas Town installation
- b2219de7: Add bootstrap documentation for new Gas Town installations
- bc82348: feat: Add gt done command (already recovered)


Spawn --molecule integration

Implement gt spawn --molecule flag for molecule-based polecat workflows.

Usage: gt spawn --issue gt-xyz --molecule mol-gastown-polecat

Behavior:
1. Validate molecule exists and is well-formed
2. Create molecule instance (child beads) under the issue
3. Find first ready step(s) in the instance
4. Spawn polecat with first ready step as initial work

Implementation:
1. Add --molecule flag to spawn command
2. Call molecule.Instantiate()
3. Query ready steps from instance
4. Pass first ready step to polecat context

Files: internal/cmd/spawn.go

Acceptance:
- --molecule flag works
- Creates proper molecule instance
- Polecat starts on first ready step
- End-to-end test with actual polecat


Deacon patrol banners: visual feedback on atom transitions

Print large ASCII banners when transitioning between patrol atoms.

## Problem

When the deacon progresses through patrol atoms (steps), there is no visual feedback.
The operator cannot easily see what the deacon is doing without reading the full output.

## Desired Behavior

Print banners on step start and completion:

  INBOX-CHECK - Checking for lifecycle requests, escalations, timers
  INBOX-CHECK COMPLETE - Processed 3 messages, 0 lifecycle requests

## Benefits

1. Scanability: Operator can glance at tmux and see what is happening
2. Progress tracking: Easy to see where in the patrol loop we are
3. Debugging: Clear demarcation between steps for troubleshooting

## Implementation Options

1. In deacon CLAUDE.md: Instruct agent to print banners
2. gt patrol step start/end: Commands that print banners
3. bd mol step hooks: Automatically on step transitions

Cross-project dependency workflow (Gas Town side)

Gas Town integration for cross-project dependencies.

## Components
- gt-zniu: gt park command (park molecule on external dep)
- gt-in3x: gt spawn --continue (resume parked molecule)
- gt-5uf3: Patrol auto-resume (future)

## Design Doc
See: docs/cross-project-deps.md

## Depends on Beads
- bd-h807: Cross-project dependency support (epic)

## Launch Plan
Phase 1 (launch): gt park + gt spawn --continue (manual resume)
Phase 2 (later): Patrol auto-resume


Track operational stats as entity/audit beads

Witness and refinery track operational stats in JSON files:
- total_merged, today_merged, total_failed (refinery)
- total_checks, total_nudges, total_escalations (witness)

For HOP entity CV tracking, these could become:
- type=audit beads (daily roll-ups of operational metrics)
- Entity chain entries showing validator activity

This provides observability and contributes to entity reputation tracking (e.g., refinery X has merged 500 PRs with 2% failure rate).

Not critical for launch but aligns with HOP Platform of Platforms vision.

Plugin surface for daemon lifecycle hooks

Allow rigs to customize daemon behavior via hooks/plugins.

## Hook Points

- on_heartbeat: Called during daemon heartbeat cycle
- on_worker_idle: Called when worker goes idle
- on_worker_stuck: Called when stuck detection triggers
- on_lifecycle_request: Called before processing lifecycle

## Configuration

```
<rig>/config/daemon-hooks.json
{
  "on_heartbeat": "./hooks/check-ci-status.sh",
  "on_worker_idle": "./hooks/maybe-assign-work.sh",
  "idle_threshold": "5m",
  "custom_signals": [
    {"name": "ci_status", "command": "./hooks/get-ci.sh"}
  ]
}
```

## Signal Contribution

Hooks can return signals that feed into decision engine:
- SKIP_POKE: Don't poke this agent
- FORCE_POKE: Override backoff, poke now
- CUSTOM_DATA: Extra context for logging

## Use Cases

- Check CI status before interrupting test runs
- Auto-assign work when worker becomes idle
- Custom stuck detection for specific workflows


File locking for concurrent access

Add file locking for concurrent access safety.

## At-Risk Files
- .gastown/swarms.json (or per-swarm state.json)
- .gastown/refinery.json
- polecats/<name>/state.json
- inbox.jsonl files

## Go File Locking
Use syscall.Flock for advisory locking:
```go
type FileLock struct {
    file *os.File
}

func AcquireLock(path string, timeout time.Duration) (*FileLock, error) {
    f, err := os.OpenFile(path+".lock", os.O_CREATE|os.O_RDWR, 0644)
    if err != nil {
        return nil, err
    }
    // Use syscall.Flock with timeout
}

func (l *FileLock) Release() error
```

## Integration Pattern
```go
func (m *Manager) saveState(ref *Refinery) error {
    lock, err := AcquireLock(m.stateFile(), 5*time.Second)
    if err != nil {
        return fmt.Errorf("could not acquire lock: %w", err)
    }
    defer lock.Release()

    // Read-modify-write cycle
}
```

## New Package
internal/filelock/
├── lock.go     # FileLock, AcquireLock
└── lock_test.go

## Apply To
- internal/refinery/manager.go: loadState/saveState
- internal/cmd/swarm.go: SwarmStore
- internal/mail/mailbox.go: Append, rewrite
- internal/polecat/manager.go: state operations

## Timeout Handling
Default 5 second timeout. Return error if lock not acquired.

## Acceptance Criteria
- [ ] Lock files created (.lock extension)
- [ ] Timeout on lock contention
- [ ] All state files protected
- [ ] Locks released on error paths


CLI: gt swarm commands (create, status, list, land)

EXTERNAL: Beads Messaging & Knowledge Graph (bd-kwro)

Tracking issue for external dependency on Beads v0.30.2 messaging features.

Beads epic: bd-kwro in ~/src/beads (steveyegge/beads repo)

This blocks GGT work that depends on:
- bd mail send/inbox/read/ack commands
- message issue type
- replies_to threading
- Hooks system for notifications
- Identity configuration

GGT mail commands will be thin wrappers around bd mail once available.

When bd-kwro ships in Beads v0.30.2, close this and unblock dependent work.


P0: Multiple agents can claim same worker identity

Multiple Claude Code sessions running simultaneously all think they are 'dave' on beads/crew/dave. No detection or prevention of identity collision. This breaks the single-agent-per-worker assumption.

## Fix Implemented

1. **Lock Package** (`internal/lock/lock.go`):
   - PID-based lockfile at `<worker>/.gastown/agent.lock`
   - Contains PID, timestamp, session ID, hostname
   - Stale lock detection (checks if owning PID is dead)

2. **Prevention in gt prime**:
   - Workers (crew/polecat) acquire identity lock before loading context
   - If another live process holds the lock, prime fails with clear error
   - Shows lock holder details and resolution steps

3. **Detection with gt agents**:
   - `gt agents check` - scans for collisions and stale locks
   - `gt agents fix` - cleans stale locks
   - JSON output available for patrol tooling

4. **Correction in gt doctor**:
   - New `identity-collision` check
   - `gt doctor --fix` cleans stale locks

MR state transitions: validate open→in_progress→closed

Enforce valid state transitions for merge-requests:

Valid transitions:
- open → in_progress (Engineer claims MR)
- in_progress → closed (merge success or rejection)
- in_progress → open (failure, reassign to worker)
- open → closed (manual rejection)

Invalid:
- closed → anything (immutable once closed)

Implement validation in MR update operations.

Town Doctor molecule for harness health checks

Create a Town Doctor molecule that any Gas Town agent can run to diagnose and repair harness issues.

## Concept

Instead of just `gt doctor` as a CLI command with hardcoded checks, create a **molecule** (checklist workflow) that:
- Any agent (Mayor, Witness, Polecat) can instantiate
- Walks the agent through diagnostic steps
- Agent uses judgment to fix issues found
- Works as a structured troubleshooting guide

## Why a Molecule?

1. **Agent-driven**: The agent running it becomes "the doctor" temporarily
2. **Extensible**: Add new checks by updating the molecule, not code
3. **Contextual**: Agent can reason about issues, not just run scripts
4. **Self-healing**: Agent can fix problems it finds, not just report them

## Proposed Checks (molecule steps)

1. Verify harness structure (mayor/, .beads/, CLAUDE.md exist)
2. Validate config files (town.json, rigs.json parse correctly)
3. Check beads health (bd doctor, redirect validity)
4. Verify git state (clean working tree, proper remotes)
5. Check rig integrity (each registered rig exists, has config.json)
6. Validate agent clones (mayor/rig/, refinery/rig/ exist and are valid)
7. Check for orphaned worktrees/branches
8. Verify daemon state (if running)

## Integration

- `gt doctor` could instantiate the molecule for the current agent
- Or agent can run `bd ready` and pick up doctor tasks when prioritized
- Results logged to beads for audit trail

CLI: gt stop --all (emergency swarm kill)

Emergency kill command for swarm operations.

## Commands

```bash
gt stop --all              # Kill ALL sessions across all rigs
gt stop --rig <name>       # Kill all sessions in one rig
gt stop --rig <name> --graceful  # Try graceful first, then force
```

## Implementation

### --all flag
1. List all tmux sessions matching gt-*
2. For each: capture final output, kill session
3. Update all polecat states to idle
4. Log all killed sessions
5. Send mail to Mayor: "Emergency stop executed"

### --rig flag
1. List sessions for specific rig
2. Same as above but scoped

### --graceful flag
1. First, try to inject "exit" command
2. Wait 5 seconds
3. If still running, force kill

## Output

```
Stopping all Gas Town sessions...
  [wyvern] Toast: captured output, killed
  [wyvern] Capable: captured output, killed
  [beads] Nux: captured output, killed

3 sessions stopped.
All polecat states set to 'idle'.
Mail sent to mayor/.
```

## Safety

- Always capture output before killing
- Update state files to reflect reality
- Log all operations to gt.log
- Warn if uncommitted changes detected (but still kill)

## Dependencies

Needs: Tmux wrapper, Session management, Polecat management
