gt mq retry: retry a failed MR

Implement 'gt mq retry <id>' to retry a failed merge request.

Actions:
1. Verify MR exists and is in failed state (open with failure labels)
2. Remove failure labels (needs-rebase, needs-fix)
3. Reset to ready state
4. Optionally re-run immediately (--now flag)

Options:
- --now: immediately process (instead of waiting for Engineer loop)

gt polecat remove --all: bulk polecat teardown

Currently gt polecat remove only accepts one polecat at a time. Need bulk operations:

## Requested
- `gt polecat remove gastown --all` - remove all polecats from a rig
- `gt polecat remove gastown/A gastown/B ...` - remove multiple by name

## Context
After a swarm completes, tearing down 20 polecats one at a time is tedious.
Ephemeral workers should be easy to create and destroy in bulk.

Add 'wit' alias for witness command

ref works as alias for refinery, but wit doesn't work for witness. Add Aliases: []string{"wit"} to witnessCmd.


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


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


Document merge queue architecture

Update docs/architecture.md with:

- Merge Queue section explaining Beads-native approach
- Engineer role (renamed from Refinery)
- Session restart protocol
- gt mq command reference
- Federation considerations for queue

Also update any references to .gastown/ → config/.


Crew workers getting wrong CLAUDE.md (shows Refinery)

## Problem

Crew workers (emma, dave) have CLAUDE.md that says they're the Refinery.

## Evidence

```
$ head -5 /Users/stevey/gt/beads/crew/emma/CLAUDE.md
# Claude: Beads Refinery
You are the **Refinery** for the **beads** rig...
```

## Expected

Should use crew.md.tmpl which correctly says:
```
# Crew Worker Context
You are a **crew worker** - the overseer's (human's) personal workspace...
```

## Impact

- Crew workers have wrong identity in static context
- `gt prime` correctly outputs crew context, but CLAUDE.md conflicts
- Confusing role information

## Fix

Check `gt crew create` or whatever populates CLAUDE.md for crew workers.


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
    }
}
```

## Files

- `internal/cloudrun/client.go`

## Dependencies

Depends on: gt-9a2.7 (protocol types)
Used by: gt-9a2.8 (CloudRunOutpost)


Work assignment mail not received by polecat

When gt spawn sends a work assignment:

1. gt spawn says '✓ Work assignment sent'
2. Polecat runs 'gt mail inbox'
3. Shows '0 messages, 0 unread'

The work assignment mail never arrived at the polecat's inbox.

## Observed in session
- Spawned polecat dementus on gt-th7
- Polecat checked inbox: empty
- Polecat couldn't find issue (separate sync bug)

## Possible causes
- Mail routing issue for polecat addresses
- gt spawn not actually sending mail
- Mail sent to wrong address format

This was likely caused by stale beads in old polecats. With gt-9nf (fresh polecats), polecats now use shared rig beads via redirect file, eliminating sync issues. Mail routing uses town beads correctly.


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

GGT is missing most polecat management commands that PGT has.

Missing Commands:
- gt polecat add <rig> <name> - Add polecat to rig (creates clone)
- gt polecat list [<rig>] - List polecats with state
- gt polecat info <polecat> - Show detailed info
- gt polecat wake <polecat> - Mark available
- gt polecat sleep <polecat> - Mark unavailable
- gt polecat decommission <polecat> - Remove polecat safely

PGT Reference: gastown-py/src/gastown/cli/polecat_cmd.py

Notes:
- spawn exists but doesn't cover management
- wake/sleep are in polecat manager but not CLI
- decommission should check for uncommitted work


CLI: workspace commands (init, add, list)

GGT needs workspace management commands beyond install.

## Commands (beyond gt-f9x.3 install)

### gt workspace list
List all rigs in current workspace.
```
gt workspace list [--json]
```
Essentially `gt rig list` but framed as workspace view.

### gt workspace add
Add existing rig to workspace (alternative to gt rig add).
```
gt workspace add <git-url> [--name NAME]
```

### gt onboard
Interactive first-time setup wizard.
```
gt onboard
```
- Prompts for workspace location
- Creates structure via gt install
- Offers to add first rig

## Note
May be redundant with gt-f9x.3 (install) and gt-u1j.16 (rig commands).
Consider if this is needed or should be closed as covered by those.

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


Use Beads issue status as spawn source of truth

Currently witness tracks spawned issues in .gastown/witness.json to prevent re-spawning:

{"spawned_issues": ["gt-abc1", "gt-def2", ...]}

This is redundant with Beads issue status (in_progress). The witness could query:
  bd list --status=in_progress

The local list serves as a performance cache to avoid querying beads every cycle. Consider:
1. Use Beads as source of truth
2. Keep local cache with TTL
3. Sync cache on witness start

This simplifies state management and ensures consistency.


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.


Witness tmux status: show polecat count under management

Add witness-specific status line showing:
- Number of polecats under management
- Active/idle status
- Maybe: last nudge time, blocked count

Implement in runWitnessStatusLine() in internal/cmd/statusline.go


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.


Mail system: message types and threading

GGT mail system needs message types and threading like PGT.

## 1. Message Types
Add to internal/mail/types.go:
```go
type MessageType string
const (
    TypeTask         MessageType = "task"         // Required processing
    TypeScavenge     MessageType = "scavenge"     // Optional first-come work
    TypeNotification MessageType = "notification" // Informational
    TypeReply        MessageType = "reply"        // Response to message
)

// Update Message struct
type Message struct {
    // existing fields...
    Type     MessageType `json:"type"`
    ThreadID string      `json:"thread_id,omitempty"`
    ReplyTo  string      `json:"reply_to,omitempty"`
}
```

## 2. Priority Levels
Expand from 2 to 4:
```go
type Priority string
const (
    PriorityLow    Priority = "low"
    PriorityNormal Priority = "normal"
    PriorityHigh   Priority = "high"
    PriorityUrgent Priority = "urgent"
)
```

## 3. CLI Updates
internal/cmd/mail.go:
- Add --type flag to send: `gt mail send ... --type task`
- Add --reply-to flag: `gt mail send ... --reply-to <msg-id>`
- Add thread command: `gt mail thread <thread-id>`

## 4. Threading Logic
NewMessage() should auto-generate thread_id if not a reply.
Reply messages inherit thread_id from original.

## Files to Modify
- internal/mail/types.go: Add types, expand Priority
- internal/mail/mailbox.go: Thread filtering
- internal/cmd/mail.go: CLI flags and thread command

## PGT Reference
gastown-py/src/gastown/mail/message.py

## Acceptance Criteria
- [ ] Messages have type field (default: notification)
- [ ] 4 priority levels supported
- [ ] Reply creates thread with shared thread_id
- [ ] gt mail thread <id> shows conversation


Merge: gt-72so

branch: polecat/Doof
target: main
source_issue: gt-72so
rig: gastown


CLI: spawn command

High-level command to spawn a polecat with work assignment.

## Command

```
gt spawn <rig>/<polecat> --issue <id>
gt spawn <rig> --issue <id>  # auto-select available polecat
gt spawn <rig>/<polecat> -m "Work on X"  # free-form task
```

## What It Does

1. Select or create polecat
2. Ensure polecat is in idle/active state
3. Assign the issue (update beads, set polecat state)
4. Start session (gt session start)
5. Inject initial context

## Options

- `--issue <id>`: Beads issue to assign
- `-m "message"`: Free-form work description
- `--create`: Create polecat if it does not exist
- `--no-start`: Assign work but do not start session

## Auto-Select Logic

If polecat not specified:
1. Look for idle polecats in rig
2. Prefer ones that worked on similar issues before
3. If none available, fail (or create if --create)

## Initial Context

Injects into session:
```
[SPAWN] You have been assigned: <issue-title>
Issue: <id>
Priority: <priority>

<description>

Work on this issue. Signal DONE when complete.
```

## Implementation

Orchestrates PolecatManager + SessionManager + Beads:
```go
func Spawn(rig, polecat, issue string, opts SpawnOptions) error
```


gt shutdown should fully cleanup polecats (worktrees, branches, inboxes)

Current gt shutdown only kills tmux sessions but leaves:

1. Git worktrees in polecats/ directory
2. Polecat branches (polecat/<name>)
3. Inbox messages
4. Beads assignee state

This causes stale polecats to be reused on next startup.

## Expected Behavior

gt shutdown should:
1. Kill all polecat tmux sessions (current behavior)
2. For each polecat with StateIdle or StateDone:
   - Remove worktree
   - Delete branch
   - Clear inbox
3. For polecats with uncommitted work:
   - REFUSE to clean up
   - Report which polecats have uncommitted changes
   - Require --force or --nuclear to proceed

## Current Code

- start.go:runImmediateShutdown() only calls t.KillSession()
- Witness cleanupPolecat() does full cleanup but isn't called by shutdown

## Fix

Either:
1. Call Witness cleanup for each polecat during shutdown
2. OR add rig.ShutdownPolecats() that does the full cleanup


gt mail send: --priority flag should work like bd mail send

UX inconsistency: gt mail send passes flags that bd mail send doesn't support.

## Root Cause

router.go line 42 passes `--priority` to bd:
```go
args = append(args, "--priority", fmt.Sprintf("%d", beadsPriority))
```

But `bd mail send` only has `--urgent` (boolean), not `--priority`.

## Fix Options

1. Add `--priority` flag to `bd mail send` (preferred - more expressive)
2. Change router to only use `--urgent` when priority=0

## Also Affected

- `--type` flag (line 46) - bd mail send doesn't have this
- `--thread-id` flag (line 51) - bd mail send doesn't have this
- `--reply-to` flag (line 56) - bd mail send doesn't have this

The router assumes bd mail send has features it doesn't have.


Design: Failure modes and recovery

Document failure modes and recovery strategies for Gas Town operations.

## Critical Failure Modes

### 1. Agent Crash Mid-Operation

**Scenario**: Polecat crashes while committing, Witness crashes while verifying

**Detection**:
- Session suddenly gone (tmux check fails)
- State shows 'working' but no session
- Heartbeat stops (for Witness)

**Recovery**:
- Doctor detects via ZombieSessionCheck
- Capture any recoverable state
- Reset agent state to 'idle'
- For Witness: auto-restart via supervisor or manual gt witness start

### 2. Git State Corruption

**Scenario**: Merge conflict, failed rebase, detached HEAD

**Detection**:
- Git commands fail
- Dirty state that won't commit
- Branch diverged from origin

**Recovery**:
- gt doctor reports git health issues
- Manual intervention recommended
- Severe cases: remove clone, re-clone

### 3. Beads Sync Conflict

**Scenario**: Two polecats modify same issue

**Detection**:
- bd sync fails with conflict
- Beads tombstone mechanism handles most cases

**Recovery**:
- Beads has last-write-wins semantics
- bd sync --force in extreme cases
- Issues may need manual dedup

### 4. Tmux Failure

**Scenario**: Tmux server crashes, socket issues

**Detection**:
- All sessions inaccessible
- "no server running" errors

**Recovery**:
- Kill any orphan processes
- tmux kill-server && tmux start-server
- All agent states reset to idle
- Re-spawn active work

### 5. Claude API Issues

**Scenario**: Rate limits, outages, context limits

**Detection**:
- Sessions hang or produce errors
- Repeated failure patterns

**Recovery**:
- Exponential backoff (handled by Claude Code)
- For context limits: session cycling (mail-to-self)
- For outages: wait and retry

### 6. Disk Full

**Scenario**: Clones, logs, or beads fill disk

**Detection**:
- Write operations fail
- git/bd commands error

**Recovery**:
- Clean up logs: rm ~/.gastown/logs/*
- Remove old polecat clones
- gt doctor --fix can clean some cruft

### 7. Network Failure

**Scenario**: Can't reach GitHub, API servers

**Detection**:
- git fetch/push fails
- Claude sessions hang

**Recovery**:
- Work continues locally
- Queue pushes for later
- Sync when connectivity restored

## Recovery Principles

1. **Fail safe**: Prefer stopping over corrupting
2. **State is recoverable**: Git and beads have recovery mechanisms
3. **Doctor heals**: gt doctor --fix handles common issues
4. **Emergency stop**: gt stop --all as last resort
5. **Human escalation**: Some failures need Overseer intervention

## Implementation

- Document each failure mode in architecture.md
- Ensure doctor checks cover detection
- Add recovery hints to error messages
- Log all failures for debugging


Design: Plugin architecture (agents-as-plugins)

Plugin system where plugins are just additional agents with identities, mailboxes, and beads access. See docs/architecture.md Plugins section. No special framework - just directory conventions and mail-based invocation.

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)

Witness daemon: heartbeat loop, spawn ephemeral agent

Background daemon for agent lifecycle and monitoring.

## Core Responsibilities

1. **Heartbeat monitoring**: Check agent health periodically
2. **Session lifecycle**: Restart agents after handoff (Witness Protection)
3. **Polecat monitoring**: Track worker progress, nudging
4. **Escalation**: Report failures to Mayor

## Session Lifecycle (Witness Protection)

The daemon enables autonomous long-running operation by cycling agent sessions:

```go
type SessionLifecycle struct {
    AgentType string  // "witness", "refinery"
    StatePath string  // path to state.json
}

func (d *Daemon) monitorSessionLifecycle(agent SessionLifecycle) {
    // 1. Detect session exit
    // 2. Check state.json for requesting_cycle: true
    // 3. If cycle requested: start new session, clear flag
    // 4. If unexpected exit: escalate to Mayor
}
```

See architecture.md Key Decision #12: Agent Session Lifecycle.

## Interface

```go
type Daemon struct {
    rig      *Rig
    polecats *PolecatManager
    sessions *SessionManager
    config   DaemonConfig
}

type DaemonConfig struct {
    HeartbeatInterval time.Duration  // default: 30s
    NudgeThreshold    int            // nudges before escalation
    MaxWorkers        int            // from rig config
}

func NewDaemon(rig *Rig) *Daemon
func (d *Daemon) Start() error
func (d *Daemon) Stop() error

// Lifecycle
func (d *Daemon) CycleSession(agentType string) error
func (d *Daemon) SpawnWorker(issueID string) error
func (d *Daemon) ShutdownWorker(polecat string) error
```

## Heartbeat Loop

Every HeartbeatInterval:
1. Check Witness session (restart if cycle requested)
2. Check Refinery session (restart if cycle requested)
3. For each active polecat: assess progress, nudge if stuck
4. Query `bd ready` for new work, spawn up to max_workers


Update config location: .gastown/ → config/

Move rig configuration from hidden .gastown/ to visible config/:
- config/rig.json: Rig configuration
- config/engineer.json: Engineer settings (test command, etc.)
- config/witness.json: Witness settings (heartbeat interval, etc.)

Hidden directories are poorly discovered by AI agents.


Policy beads: config in data plane

Use sentinel/policy beads for configuration instead of external config. Examples: daemon notifications on/off, heartbeat intervals. Config lives in the bead graph, can be toggled by closing/opening policy beads.


Update documentation for new config architecture

Update docs to reflect new structure:
- docs/architecture.md: Directory structure section
- CLAUDE.md files: Config references
- Add docs/configuration.md with full reference


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.

Reference: docs/merge-queue-design.md#state-machine


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.


GGT Command Parity: Complete gt command coverage

Complete gt command set to match/exceed PGT town commands.

Covers: uninstall, rig info, refinery attach, witness, session mgmt, mail UX, daemon.


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


Merge: gt-3x0z.3

branch: polecat/rictus
target: main
source_issue: gt-3x0z.3
rig: gastown


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


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.


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


CLI: witness commands (start, stop, status)

Witness daemon CLI commands.

## Commands

### gt witness start
Start the witness daemon for a rig.
```
gt witness start <rig> [--interval <seconds>]
```
- Starts background daemon process
- Default heartbeat interval: 30s
- Logs to <rig>/witness/witness.log

### gt witness stop
Stop the witness daemon.
```
gt witness stop <rig>
```
- Graceful shutdown
- Completes current heartbeat cycle

### gt witness status
Show witness status.
```
gt witness status <rig> [--json]
```
Output:
- Running/stopped
- Last heartbeat time
- Polecats being monitored
- Recent nudges/escalations

### gt witness logs
View witness logs.
```
gt witness logs <rig> [--follow] [--lines <n>]
```
- --follow: Continuous output (like tail -f)
- --lines: Number of lines (default 50)

## Daemon Management

Witness runs as background process:
- PID stored in <rig>/witness/witness.pid
- Uses nohup for persistence
- Logs structured JSON events

## Implementation

```go
var witnessCmd = &cobra.Command{Use: "witness"}
witnessCmd.AddCommand(startCmd, stopCmd, statusCmd, logsCmd)
```

Start launches daemon via exec, status reads PID file and pings process.

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).


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.

mol-swarm-cleanup: Post-swarm debris cleanup molecule

After a 20+ worker swarm completed, found significant beads debris:
- 18 stale messages (work assignments, lifecycle requests, swarm instructions)
- 3 completed issues still open/in_progress
- Test messages accumulated

Need: Document a post-swarm checklist or create gt swarm cleanup command that:
1. Closes stale work assignment messages
2. Reviews in_progress issues for completion
3. Closes orphaned lifecycle messages
4. Optionally archives test messages


Agent monitoring and status inference

Agent monitoring with status inference from activity, like PGT.

## Agent Status Enum
```go
type AgentStatus string
const (
    StatusAvailable AgentStatus = "available"
    StatusWorking   AgentStatus = "working"
    StatusThinking  AgentStatus = "thinking"
    StatusBlocked   AgentStatus = "blocked"
    StatusWaiting   AgentStatus = "waiting"
    StatusReviewing AgentStatus = "reviewing"
    StatusIdle      AgentStatus = "idle"
    StatusPaused    AgentStatus = "paused"
    StatusError     AgentStatus = "error"
    StatusOffline   AgentStatus = "offline"
)
```

## Status Sources (priority order)
```go
type StatusSource string
const (
    SourceBossOverride StatusSource = "boss"      // Witness/Mayor sets
    SourceSelfReported StatusSource = "self"      // Agent reports own status
    SourceInferred     StatusSource = "inferred"  // Detected from activity
)
```

## Activity Detection

### Pattern Registry
```go
var activityPatterns = []struct {
    Pattern string
    Status  AgentStatus
}{
    {"Thinking...", StatusThinking},
    {"BLOCKED:", StatusBlocked},
    {"Error:", StatusError},
    // etc
}
```

### Idle Detection
No pane output for N seconds → StatusIdle

### Resource Monitoring (optional)
CPU/memory via os.Process

## New Package
internal/monitoring/
├── types.go      # AgentStatus, StatusReport
├── detector.go   # PatternRegistry, detect from output
├── tracker.go    # Per-agent status tracking
└── idle.go       # Idle timeout detection

## Integration
- Session capture output → monitoring detector
- Status shown in gt status, gt session list

## PGT Reference
gastown-py/src/gastown/monitoring/

## Acceptance Criteria
- [ ] Status enum with 10 states
- [ ] Pattern-based detection from pane output
- [ ] Idle detection with configurable timeout
- [ ] Status visible in CLI output


Improve test coverage in low-coverage packages

Several packages have low test coverage:
- internal/cmd: 6.8%
- internal/mail: 3.6%
- internal/daemon: 12.1%
- internal/doctor: 14.5%
- internal/refinery: 20.6%
- internal/session: 27.8%
- internal/git: 28.8%

Priority should be given to mail, cmd, and daemon packages which handle critical functionality.


Machine registry: Store and manage machine configs

Registry for managing remote machines in federation.

## Data Model

```go
type Machine struct {
    Name     string `json:"name"`
    Type     string `json:"type"`      // "local", "ssh", "gcp"
    Host     string `json:"host"`      // for ssh: user@host
    KeyPath  string `json:"key_path"`  // SSH key path
    TownPath string `json:"town_path"` // Path to town on remote
}
```

## Interface

```go
type MachineRegistry struct {
    path     string  // config/federation.json
    machines map[string]*Machine
}

func NewMachineRegistry(configPath string) *MachineRegistry
func (r *MachineRegistry) Get(name string) (*Machine, error)
func (r *MachineRegistry) Add(m *Machine) error
func (r *MachineRegistry) Remove(name string) error
func (r *MachineRegistry) List() []*Machine
func (r *MachineRegistry) Connection(name string) (Connection, error)
```

## Storage

federation.json in config/:
```json
{
  "version": 1,
  "machines": {
    "local": {"type": "local"},
    "gcp-vm-1": {
      "type": "ssh",
      "host": "user@10.0.0.1",
      "key_path": "~/.ssh/gcp_key",
      "town_path": "/home/user/ai"
    }
  }
}
```

## Connection Factory

```go
func (r *MachineRegistry) Connection(name string) (Connection, error) {
    m := r.machines[name]
    switch m.Type {
    case "local":
        return NewLocalConnection(), nil
    case "ssh":
        return NewSSHConnection(m.Host, m.KeyPath), nil
    }
}
```


gt spawn --continue for resuming parked molecules

Add `--continue` flag to gt spawn for resuming parked molecules:

```bash
gt spawn --continue gt-mol-root
```

This:
1. Finds molecule root
2. Verifies molecule is in "parked" state (in_progress, no assignee)
3. Checks external deps are now satisfied
4. Spawns polecat with molecule context
5. Polecat reads handoff mail and continues from blocked step

Part of cross-project dependency system.
See: docs/cross-project-deps.md

Depends on: gt-zniu (gt park)
Depends on Beads: bd-zmmy (bd ready resolution)


TODO: Check if issue is child of configured epic in Witness

witness/manager.go:688 has a TODO to filter issues by whether they're children of the configured epic. Currently this filter is skipped.


Resource Beads: Leases, locks, and quotas

Resource beads represent reserved resources. Types: vm, lock, slot, quota. Fields: holder, expires, renewable. Daemon monitors for expiry and manages contention.


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.


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.


Daemon: verify requesting_cycle before kill

Per gt-gby spec, daemon should verify agent state shows requesting_cycle=true before killing session. Currently kills on any lifecycle request without verification.

Requires state.json in agent workspace with requesting_cycle field.


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"
```

Configuration in Beads: use pinned beads for rig/agent config

## Summary

Move configuration from JSON files into Beads data plane using pinned beads.

## Motivation

- Config becomes versionable and syncable like issues
- Agents can read config via `bd show`
- Unified data model for everything
- Supports the 'Beads as Universal Data Plane' vision (gt-aqm)

## Config Types to Migrate

### Rig-level (pinned per rig)
- Theme/colors for tmux status line
- Default branch naming conventions
- Merge queue settings
- Witness thresholds

### Agent-level (pinned per role)
- Handoffs (already planned - gt-cu7r)
- Agent preferences
- Current focus/context

### Town-level (pinned at town root)
- Cross-rig settings
- Federation config
- Global themes

## Implementation

1. Implement StatusPinned (beads-6v2) ✓ in progress
2. Create config pinned beads on rig init
3. Add `bd config get/set` commands that read/write pinned beads
4. Migrate existing config.json fields

## Naming Convention

```
<prefix>-cfg-<scope>
gt-cfg-theme      # gastown theme
bd-cfg-merge      # beads merge settings
gm-cfg-town       # town-level config
```

## Dependencies

- beads-6v2: Add StatusPinned to beads schema
- gm-w13: Pinned Beads epic

Implement gt sling command

The unified work dispatch command.

```bash
gt sling <thing> <target> [options]
```

Implements spawn + assign + pin in one operation. See sling-design.md.

Acceptance:
- [ ] Parse thing (proto name, issue ID, epic ID)
- [ ] Parse target (agent address)
- [ ] Spawn molecule if proto
- [ ] Assign to target agent
- [ ] Pin to agent's hook (pinned bead)
- [ ] Support --wisp flag for ephemeral
- [ ] Support --molecule flag for issue+workflow
- [ ] Error if hook already occupied (unless --force)

Daemon: configurable heartbeat interval

Heartbeat interval is hardcoded to 60s. Should be configurable via:
- town.json config
- Command line flag
- Environment variable

Default 60s is reasonable but some deployments may want faster/slower.


gt spawn should use bd mol run for molecule attachment

Simplify Gas Town to use bd mol run for work tracking.

## Key Insight
Two distinct mechanisms, not duplicative:

| Mechanism | Purpose | Query |
|-----------|---------|-------|
| **Pinned molecule** (bd mol run) | What am I working on? | `bd list --pinned --assignee=me` |
| **Handoff mail** | Context notes for restart | `gt mail read` (self-addressed) |

The handoff is just **mail to yourself** - optional context notes.
The molecule is **the actual work** - required state.

## Current State (Overengineered)
Gas Town has custom attachment system:
- Permanent "Foo Handoff" pinned beads per identity
- AttachMolecule(pinnedBeadID, moleculeID)
- Attachment fields parsed from description
- Separate from beads pinning

## New Model (Simplified)
Use bd mol run directly:

```bash
# Spawn polecat with molecule
bd mol run mol-polecat-work --var issue=gt-xyz
# This: spawns, assigns to caller, pins root, sets in_progress
```

Query current work:
```bash
bd list --pinned --assignee=gastown/furiosa --status=in_progress
```

Handoff context (when needed):
```bash
gt mail send gastown/furiosa -s "Context notes" -m "Was on step 4..."
```

## Changes Required

### Remove from Gas Town
- AttachMolecule() / DetachMolecule()
- AttachmentFields struct and parsing
- GetAttachment() / SetAttachmentFields()
- Permanent pinned handoff beads per identity
- Daemon attachment detection (checkDeaconAttachment)

### Update gt spawn
```go
// Old: custom molecule instantiation + attachment
// New: just call bd mol run
cmd := exec.Command("bd", "mol", "run", protoID, "--var", "issue="+issueID)
```

### Update gt prime / agent context
```go
// Old: find handoff bead, parse attachment
// New: query for pinned molecule
cmd := exec.Command("bd", "list", "--pinned", "--assignee="+identity, "--status=in_progress", "--json")
```

### Update documentation
- Remove handoff bead attachment docs
- Clarify: handoff = mail, molecule = work
- Update CLAUDE.md templates

## Benefits
1. One system for work tracking (beads)
2. Simpler Gas Town code
3. bd mol squash works naturally
4. Handoff is just mail (already works)

Verify architecture.md shows correct harness and rig structure

Review architecture.md diagrams:
- Verify town-level structure shows harness correctly
- Confirm rig-level mayor/rig/ is shown (it appears to be there at line 197)
- Check mermaid diagrams match ASCII diagrams
- Update if any inconsistencies found
- Cross-reference with new harness.md docs


Harness Design & Documentation

The harness (Gas Town installation directory) needs design cleanup, documentation, and tooling.

## Current Problems

1. **Shared harness confusion**: ~/ai is shared by PGT and GGT with overlapping structures
   - PGT uses ~/ai/mayor/ as town-level Mayor home
   - GGT Mayor works in ~/ai/mayor/rigs/gastown/
   - ~/ai/gastown/ has both .gastown/ (PGT) and mayor/ (git clone)

2. **Beads redirect**: ~/ai/.beads/redirect → mayor/rigs/gastown/.beads
   - This is specific to GGT's decentralized structure
   - Should be documented as an example

3. **architecture.md**: Verify rig-level mayor/rig/ is shown correctly

4. **No harness creation tooling**: Users must manually set up

## Proposed Work

- Document what a harness IS (installation directory)
- Create harness creation command or template repo
- Update architecture.md if needed
- Create example harness configuration for docs
- Resolve PGT/GGT sharing issue


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 mail: Cross-level routing is broken

**Problem:**
When Mayor (at ~/gt) sends mail to a rig worker (gastown/crew/max), the message lands in town-level beads (~/.beads/) but the recipient checks rig-level beads (crew/max/.beads/).

**Reproduction:**
```bash
cd ~/gt
gt mail send gastown/crew/max -s 'Test' -m 'body'
# Message goes to ~/gt/.beads/ with prefix hq-*

cd ~/gt/gastown/crew/max
gt mail inbox
# Does NOT see the message - it's looking in crew/max/.beads/
```

**Root cause:**
`findBeadsWorkDir()` walks up from CWD to find .beads. `Router.Send()` runs `bd create` in that directory. This means messages always go to the sender's beads, not the recipient's.

**Fix options:**
1. Route based on recipient address - if sending to rig/*, use that rig's .beads
2. Use a single shared beads database for all mail (simpler but less isolated)
3. Teach agents to check both levels (workaround, not fix)

**Related:**
- gt-ngu1: Pinned beads sorting (done but pointless if mail doesn't route)
- This blocks all cross-level mail functionality


Preflight molecule: verify baseline health before work

Before assigning work, verify baseline (main branch) is healthy.

**From VC**: Self-healing state machine (HEALTHY → SELF_HEALING → ESCALATED). ~200 lines.

**Gas Town implementation**: Preflight molecule or refinery feature:
```yaml
preflight:
  gates: [test, lint, build]
  on_failure: create-fix-issue
```

Run at session start. If baseline broken, file a P0 fix issue and work on that first.

**Value**: Self-healing baseline. Agents don't start from broken state.

**VC lesson**: Prevents cascading failures. Agent shouldn't start work on broken code.


Create rig settings/ directory for rig configuration

Replace .gastown/ with visible settings/ at rig level:
- Create <rig>/settings/ directory
- Move .gastown/config.json → settings/config.json (theme, merge_queue, max_workers)
- Create settings/namepool.json for pool settings (style, max - not state)
- Create settings/roles/ for per-role overrides (optional)
- Update RigConfig type to reference settings/
- Update loader to read from settings/


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


Define constants for magic strings

Several magic strings are hardcoded throughout the codebase:
- "mayor" appears in 20+ places as a path component
- "main" branch name appears in 20+ places
- "beads-sync" branch name in multiple files
- "rigs.json" filename

These should be constants in a central location for maintainability.

TIDY UP: Your previous work (patrol runner) was already merged to main. Check your git status is clean, sync beads, and if nothing to do, just run 'gt done'.


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


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-test123 - The source issue ID being worked on


Daemon: proper rig discovery

Currently discovers rigs by scanning tmux session names for gt-*-witness pattern. Should instead:
- Read rigs from mayor/rigs.json
- Or scan town directory for .gastown subdirs
- Handle rigs that exist but don't have running witnesses


Overhaul gt mol to match bd mol chemistry interface

## The Sling: Unified Work Dispatch

This issue tracks the overhaul of `gt molecule` to align with chemistry metaphor and introduce the **Universal Gas Town Propulsion Principle**.

### The Propulsion Principle

> **If you find something on your hook, YOU RUN IT.**

This is the one rule that drives all Gas Town agents.

### The Sling Operation

`gt sling <thing> <target> [options]` - unified command for spawn + assign + pin.

See: `gastown/mayor/rig/docs/sling-design.md`

### Implementation Tasks

| Issue | Title | Priority |
|-------|-------|----------|
| gt-4ev4 | Implement gt sling command | P1 |
| gt-uym5 | Implement gt mol status command | P1 |
| gt-i4kq | Update templates for Propulsion Principle | P1 |
| gt-7hor | Document the Propulsion Principle | P2 |

### Command Changes

| Old | New |
|-----|-----|
| `gt molecule instantiate` | `gt sling` |
| `gt molecule attach` | `gt sling --force` |
| `gt molecule detach` | `gt mol burn` |
| `gt molecule progress` | `gt mol status` |
| `gt molecule list` | `gt mol catalog` |
| `gt spawn --molecule` | `gt sling` |

### Acceptance Criteria

- [ ] `gt sling` works for protos, issues, and epics
- [ ] `gt mol status` shows hook state
- [ ] Templates updated for propulsion principle
- [ ] Old commands deprecated with warnings
- [ ] Documentation complete


gt prime: Refinery context detection and output

Update gt prime to detect Refinery role:
- Detect from directory: refinery/rig/ = Refinery
- Show handoff bead reference
- Show merge queue status
- Show polecat branches with unmerged commits
- Show last actions summary


Mail coordination should use town-level database

gt mail send/inbox should use ~/gt/.beads (town root) not rig-local beads. Cross-rig mail coordination (Witness <-> Mayor, polecat <-> Witness) needs to be in a shared location.

gt spawn should auto-start refinery/witness if not running

When spawning a polecat, the infrastructure (refinery, witness) should already be running.

## Current Behavior
spawn.go only:1. Assigns issue to polecat2. Sends work mail3. Starts polecat session

The refinery and witness must be started separately.

## Expected Behavior (per user feedback)
When spawning a polecat, if the rig's refinery or witness is not running, auto-start them.

## Options

### Option A: spawn auto-starts infrastructure
Check if refinery/witness running before spawn, start if not.

### Option B: gt swarm start <rig> command
Explicit command that:
1. Starts refinery
2. Starts witness
3. Optionally spawns polecats on bd ready issues

### Option C: gt rig start <rig>
Similar to Option B but as rig lifecycle command.

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


Federation: Wasteland architecture for cross-town coordination

## Overview

Federation enables Gas Town to scale across machines via **Outposts** - remote compute environments that can run workers.

**Design doc**: docs/federation-design.md

## Outpost Types

| Type | Description | Cost Model |
|------|-------------|------------|
| Local | Current model (tmux panes) | Free |
| SSH/VM | Full Gas Town clone on VM | Always-on |
| CloudRun | Container workers on GCP | Pay-per-use |

## Key Concepts

### Outpost Abstraction
```go
type Outpost interface {
    Name() string
    Type() OutpostType  // local, ssh, cloudrun
    MaxWorkers() int
    Spawn(issue string, config WorkerConfig) (Worker, error)
    Workers() []Worker
    Ping() error
}
```

### Cloud Run Workers
- Persistent HTTP/2 connections solve zero-to-one cold start
- Pay only when working (~$0.017 per 5-min session)
- Scale 0→N automatically
- Git clone via persistent volumes

### SSH/VM Outposts
- Full Gas Town clone on remote machine
- SSH for commands, git for sync
- Good for long-running autonomous work

## Design Principles

1. **Outpost abstraction** - support multiple backends
2. **Local-first** - remote is for overflow/burst
3. **Git as source of truth** - code and beads sync everywhere
4. **HTTP for Cloud Run** - dont force mail onto containers
5. **Graceful degradation** - works with any subset of outposts

beads: Stop searching upward when .beads found

## Problem

When running bd commands in a nested directory structure with multiple .beads directories, bd shows a confusing warning:

```
╔══════════════════════════════════════════════════════════════════════════╗
║ WARNING: 2 beads databases detected in directory hierarchy              ║
╠══════════════════════════════════════════════════════════════════════════╣
║ Multiple databases can cause confusion and database pollution.          ║
║                                                                          ║

║ RECOMMENDED: Consolidate or remove unused databases to avoid confusion. ║
╚══════════════════════════════════════════════════════════════════════════╝
```

## Why This Is Wrong

In Gas Town, nested .beads directories are **intentional and necessary**:
- Town level: /Users/stevey/gt/.beads (mail, town-level issues)
- Rig level: /Users/stevey/gt/gastown/.beads (gastown project issues)
- Worker level: polecats have their own beads in worktrees

These are **unrelated** beads instances for different scopes. They should never be consolidated.

## Expected Behavior

When bd finds a .beads directory, it should:
1. Use that directory (closest ancestor wins)
2. **Stop searching upward** - do not look for parent .beads directories
3. **No warning** about multiple databases

## Current Behavior

bd searches all the way up to root, finds all .beads directories, and warns about "multiple databases" even though they are separate, intentional instances.

## Fix

In the database discovery code, stop the upward search as soon as a .beads directory is found. The first .beads found is the one to use, and parent directories are out of scope.

## Note

This is a beads issue, filed here for tracking. Should be implemented in the beads codebase.


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.


Rollback support: gt mq revert for problematic merges

Implement 'gt mq revert <mr-id>' for rolling back merges.

Actions:
1. Find merge commit from closed MR
2. Create revert commit: git revert <merge-commit>
3. Push revert to target branch
4. Create 'reverted' MR tracking the revert
5. Optionally reopen source issue

Options:
- --reason REASON: required explanation
- --reopen-issue: reopen the source work item

Track revert in MR metadata for audit trail.

Reference: docs/merge-queue-design.md#open-questions


Molecule schema: YAML format for workflow definitions

Define the YAML schema for molecule definitions:

```yaml
molecule: <name>
version: 1
description: "Human description"
steps:
  - id: <step-id>
    title: "Step title"
    prompt: "Instructions for agent"
    depends: [<other-step-ids>]  # optional
    tier: haiku|sonnet|opus      # optional, default from config
    timeout: 30m                 # optional
```

Store molecules in:
- `<rig>/molecules/<name>.yaml` for rig-specific
- `<town>/molecules/<name>.yaml` for town-wide

Built-in molecules to ship:
- engineer-in-box: design→code→review→test→submit
- quick-fix: implement→test→submit
- research: investigate→document


Tech Debt: Code Review December 2024

Tech debt identified during code review on 2024-12-21. Contains 11 issues ranging from P2-P4 covering:

- Code duplication (manager creation boilerplate)
- Test coverage gaps (cmd 6.8%, mail 3.6%)
- Magic strings needing constants
- Error handling inconsistencies
- Large files needing splitting
- Unused code removal

Work through these incrementally to improve codebase maintainability.


Polecat name pooling: Bounded reusable names

Polecats reuse names from a bounded pool (50) with overflow to sequence numbers.

## Naming Scheme
- Pool: polecat-01 through polecat-50 (prefer low numbers)
- Overflow: <rigname>-<sequenceNumber> (e.g., beads-51, gastown-52)

## Design
- Witness tracks which pool names are in use
- On spawn: pick first available from pool
- If pool exhausted: use rigname-N format
- On completion: pool name returns, sequence numbers don't

## Why?
- User experience: tmux sessions survive polecat restarts
- Users stay attached, see new polecat start (like mayor respawn loop)
- Bounded resource usage for common case
- Scales beyond 50 when needed

## Implementation
- Witness maintains name allocation in beads or local state
- Tmux session runs respawn loop (like mayor)
- Name released on graceful exit or when witness detects dead session


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


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.


Pinned Beads: Ongoing concerns and anchors

Pinned beads represent persistent concerns that do not close traditionally. Stay out of bd ready. Examples: Monitor production, Weekly syncs. Implementation: pinned: true field on bead.


Merge: gt-5af.2

branch: polecat/Doof
target: main
source_issue: gt-5af.2
rig: gastown


Add bulk polecat remove command (gt polecat remove --all)

When decommissioning a rig, need to remove multiple polecats one at a time. A --all or --rig flag would allow: gt polecat remove --rig gastown --force


Phase 2: Quiescent agents (Witness, Refinery)

Enable Witness and Refinery to sleep until triggered.

## Scope
- Wake triggers: gt spawn, MR submit, mail, Deacon ping
- Wake SLA: <1 minute
- mol-witness-patrol and mol-refinery-patrol definitions
- Quiescent entry/exit protocol

## Implementation
- Kill tmux session on quiescent entry
- Preserve sandbox (worktree, state files)
- Restart session on wake trigger
- Agent checks pinned, spawns default patrol if naked

Depends: Phase 1 complete

## Test Categories

### Unit Tests
- Config parsing
- Mail operations
- Merge queue operations
- Template rendering

### Integration Tests
- Git operations (uses real git in temp dirs)
- Full workflows (spawn → work → merge)
- CLI command tests

## Fixtures

```go
package testutil

// Creates temp town with minimal structure
func NewTestTown(t *testing.T) *TestTown

// Creates temp rig with git repo
func NewTestRig(t *testing.T, town *TestTown, name string) *TestRig

    Sessions map[string][]string  // captured send-keys
}

func (m *MockTmux) NewSession(name, dir string) error
func (m *MockTmux) SendKeys(session, keys string) error
func (m *MockTmux) CapturePane(session string, lines int) (string, error)
```

## Test Helpers

```go
// Run test in temp directory
func InTempDir(t *testing.T, fn func(dir string))

// Initialize git repo for testing
func InitGitRepo(t *testing.T, dir string)

// Assert file exists with content
func AssertFileContains(t *testing.T, path, substr string)

// Assert JSON file has field
func AssertJSONField(t *testing.T, path, field string, expected any)
```

## CI Integration

- go test ./... runs all tests

## Test Data

Embedded test fixtures:
```go
//go:embed testdata/*
var testdataFS embed.FS
```


Plugin: work-oracle (pre-dispatch analysis)

Plugin for pre-dispatch task analysis and decomposition.

## Purpose

Before dispatching workers for an epic, ask work-oracle to:
- Validate task breakdown
- Identify parallelization opportunities
- Predict conflicts between tasks
- Suggest worker count

## Hook Point

Mayor consults work-oracle before spawning workers.

## Interface

Input (via mail):
- Epic ID with proposed child issues
- Rig context (current state of codebase)

Output (via mail + bead):
- Recommended task groupings
- Dependency suggestions
- Risk assessment (which files might conflict)
- Optimal worker count

## Structure

```
<rig>/plugins/work-oracle/
├── CLAUDE.md       # Analysis prompts
├── mail/inbox.jsonl
└── state.json
```

Uses existing plugin-as-agent architecture.

## Note

Was "swarm-oracle" - renamed because there are no swarm IDs. This plugin helps plan batch work, not manage swarm entities.


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.


Replaceable notifications via Claude Code queue

Leverage Claude Code's ability to replace queued text for notifications that supersede previous ones.

## Problem

If daemon sends 10 heartbeats while agent is busy, agent returns to see 10 stacked messages. Wasteful and noisy.

## Solution

Use Claude Code's queue replacement for:
- Heartbeat messages (only latest matters)
- Status updates that supersede previous
- Progress notifications

## Implementation

Notifications get a 'slot' identifier. New notification in same slot replaces old one:
- Slot: 'heartbeat' → only one heartbeat queued at a time
- Slot: 'status-<rig>' → latest status per rig
- No slot → stacks normally (for unique messages)

## Research Needed

- How does Claude Code expose queue replacement?
- tmux send-keys behavior with pending input
- Alternative: clear + resend pattern


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)


inbox-check

Handle callbacks from agents. Check gt mail inbox, process lifecycle requests.


mol-code-review: Self-improving code review molecule

Create a code review molecule that enables Gas Town to self-improve through automated PR review. Flywheel: review generates quality checks, discovered issues, pattern learning.


Witness swarm landing protocol

Witness responsibilities for swarm landing cleanup.

## Trigger

Witness receives "swarm-landed" mail from Refinery containing:
- swarm_id
- merge_commit
- action: "cleanup"

## Landing Protocol

### Phase 1: Preflight
Verify all polecat sessions stopped:
- Check tmux for active sessions
- Kill any remaining sessions
- Wait for graceful shutdown

### Phase 2: Git Audit
For each polecat in swarm:
- Check for uncommitted changes
- Check for unpushed commits
- Check for stashes
- Classify as "beads-only" (safe) or "code at risk"
- If code at risk: escalate, abort landing

### Phase 3: Cleanup
For each polecat:
- Clear state entry (mark as idle)
- Delete inbox (or archive)
- Delete worker branch (local + remote)

### Phase 4: Final Report
- Update swarm state to "landed"
- File landing report bead
- Mail Mayor with summary

## Code at Risk Handling

If git audit finds code at risk:
1. Abort cleanup for that polecat
2. Mail Mayor with details
3. Human intervention required

## Reference

PGT: swarm/landing.py (6-phase protocol), swarm/git_audit.py


gt mq integration create: create integration branch for epic

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

Actions:
1. Verify epic exists
2. Create branch: integration/<epic-id> from main
3. Push to origin
4. Store integration branch info in epic metadata

Usage:
  gt mq integration create gt-auth-epic
  # Creates integration/gt-auth-epic from main

Future MRs for this epic's children will auto-target this branch.

Reference: docs/merge-queue-design.md#integration-branches

gt doctor: detect orphaned code on beads-sync branch

After merging beads-sync to main, some code changes can be lost if the merge conflict resolution drops files.

Add a doctor check that runs:
  git diff main..beads-sync -- '*.go' '*.md'

If there are differences in code files (not just .beads/), warn about potentially orphaned work.

Today's incident: Merge 96c773f lost mailbox.go and router.go changes from 5791752, requiring re-implementation.

Acceptance:
- gt doctor warns if beads-sync has unmerged code changes
- Excludes .beads/ directory (expected to differ)
- Shows file list of orphaned changes


Witness role template + CLAUDE.md

Create the Witness agent's role context:

1. internal/templates/roles/witness.md.tmpl
   - Witness responsibilities (polecat lifecycle)
   - Core loop description
   - Commands available (gt polecats, bd ready, etc)
   - Escalation protocol

2. Generate CLAUDE.md for witness/ directories
   - Context about the rig
   - Mail address: <rig>/witness
   - Startup protocol (gt prime, check inbox)

The Witness is the per-rig 'pit boss' - NOT a global coordinator. It manages polecats for ONE rig only.


Add deacon/ mail identity support

Ensure deacon/ works as a mail identity in town-level beads. Test with bd mail send deacon/ and bd mail inbox --identity deacon/.


Speed up test suite

Tests are running slow during MQ processing. Investigate and optimize:
- Profile test execution time
- Look for slow tests (network, file I/O, sleeps)
- Consider parallel test execution
- Cache expensive setup where possible


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

CLI commands for swarm management.

## Commands

### gt swarm create
Create a new swarm in a rig.

```
gt swarm create <rig> --title "Fix all P1 bugs" \
  --task gt-abc --task gt-def \
  --worker Toast --worker Nux
```

Options:
- --title: Swarm title (required)
- --task: Beads issue IDs to include (repeatable)
- --worker: Polecat names (repeatable, or --workers=3 to auto-assign)
- --start: Start swarm immediately after creation

### gt swarm status <swarm-id>
Show swarm status and progress.

Output:
- Swarm metadata (title, created, workers)
- Task status (pending/in_progress/completed/merged)
- Integration branch status
- Overall progress percentage

### gt swarm list [rig]
List swarms, optionally filtered by rig or status.

```
gt swarm list --status=active
gt swarm list gastown --status=landed
```

### gt swarm land <swarm-id>
Trigger manual landing (normally automatic).

### gt swarm cancel <swarm-id>
Cancel a swarm in progress.

## Output Format

Support --json for machine-readable output.

## Dependencies

Needs: gt-kmn.1 (types), gt-kmn.2 (manager)


Deacon rounds molecule: the kernel execution loop

Define and implement mol-deacon-rounds - the molecule the Deacon executes each wake.

## Molecule Definition

```markdown
# mol-deacon-rounds

The Deacon kernel - executed on every wake cycle.

## Step: session-check
Check context budget. If low, cycle to fresh session.
Needs: (none - always runs first)

## Step: health-scan
Check health of all monitored agents:
- Mayor (gt-mayor session)
- Witnesses (gt-*-witness sessions)
- Refineries (gt-*-refinery sessions)
- Crew (gt-*-* sessions, lifecycle only)

Remediate unhealthy agents:
- Restart dead sessions
- Nudge stuck agents
- Escalate if remediation fails

Needs: session-check

## Step: lifecycle
Process pending lifecycle requests from mail:
- LIFECYCLE: <identity> requesting cycle
- LIFECYCLE: <identity> requesting restart
- LIFECYCLE: <identity> requesting shutdown

Needs: health-scan

## Step: plugins
Run due plugins:
1. Check scheduled plugins (cron-like)
2. Check event-triggered plugins (from mail events)
3. Check human-requested plugins (from mail)
4. Execute each, record outcomes

Needs: lifecycle

## Step: events
Process timer and event callbacks:
- TIMER: <identity> wake at <time>
- EVENT: <type> <payload>

Notify relevant agents or trigger actions.

Needs: plugins

## Step: complete
Finalize the cycle:
1. Update heartbeat.json
2. Clear/update keepalive.json
3. Log summary
4. Return to prompt (wait for next wake)

Needs: events
```

## Execution

The Deacon reads this molecule from its pinned bead and executes steps in order.
Each step:
1. Announces "Starting <step>"
2. Performs the step logic
3. Records outcome
4. Proceeds to next step

## Step Plugins

Each step can have inline plugins (additional attention):
```yaml
step: health-scan
  plugins:
    - advanced-diagnostics  # Run if basic scan finds issues
```

## Relation to bd mol

Uses the same molecule format as bd mol for polecats.
Deacon molecule is special: it's the kernel, not work.


gt spawn: pasted work assignment needs manual Enter to start

## Problem

After `gt spawn` pastes the work assignment into Claude, the session waits for Enter.

## Current Behavior

1. `gt spawn gastown/Rictus --issue gt-xxx`
2. Session starts, work is pasted
3. Claude shows 'Pasted text #1 +53 lines' but doesn't start
4. Must manually send Enter or attach and press Enter

## Expected

The spawn should send Enter after pasting to kick off the work.

## Related

Same debounce issue as tmux notifications (gt-vnp9).


Integration branch management for swarms

Manage integration branches for swarm merging strategy.

## Branch Naming

- Integration branch: `integration/<swarm-id>` (e.g., integration/sw-1)
- Worker branches: `<swarm-id>/<polecat>` (e.g., sw-1/Toast)

## Operations

```go
// Create integration branch at swarm start
func (m *SwarmManager) CreateIntegrationBranch(swarmID string) error
// - Creates from BaseCommit
// - Pushes to origin

// Merge worker branch to integration
func (r *Refinery) MergeToIntegration(swarmID, workerBranch string) error
// - Fetches worker branch
// - Merges to integration/<swarm-id>
// - Handles conflicts (semantic merge)

// Land integration to main
func (r *Refinery) LandToMain(swarmID string) error
// - Merges integration/<swarm-id> to main
// - Pushes to origin
// - Triggers cleanup

// Cleanup branches after landing
func (m *SwarmManager) CleanupBranches(swarmID string) error
// - Deletes integration/<swarm-id> (local + remote)
// - Deletes all <swarm-id>/<polecat> branches
```

## All Workers Same Base

When swarm starts:
1. Record current main HEAD as BaseCommit
2. All polecats branch from BaseCommit
3. Integration branch also starts at BaseCommit

This ensures clean merges within the swarm.

## Reference

PGT: ephemeral.py (create_integration_branch, merge_integration_to_main)


Refinery background daemon mode

The refinery 'gt refinery start' command only works in foreground mode (--foreground). Need to implement background daemon mode for production use.

Options:
1. Use a separate tmux session for the refinery
2. Implement proper daemonization
3. Use Claude Code session for the refinery agent

For MVP, option 1 (tmux session) is probably simplest.


Refinery semantic merge processing loop

Implement the Refinery semantic merge loop for processing polecat work.

## Overview

The Refinery is a fully empowered Claude Code agent that:
1. Fetches polecat branches
2. Merges to integration branch
3. Resolves conflicts semantically (re-implements if needed)
4. Runs tests
5. Escalates only when truly stuck

## Processing Loop

1. Check queue for completed tasks (polecat done, not yet merged)
2. For each task:
   - Fetch polecat branch
   - Attempt merge to integration/<swarm-id>
   - On conflict: semantic resolution (understand intent, re-implement)
   - Run tests if configured
   - On success: mark merged, file bead, notify witness
   - On failure: notify polecat (test fail) or escalate (stuck)
3. When all tasks merged: land integration to main

## Semantic Merge

When git merge fails, Refinery:
1. Reads polecat changes and beads issue
2. Understands intent
3. Re-implements on current integration branch
4. Only escalates if truly blocked

## Daemon Poking

Refinery is poked by:
- Daemon heartbeat (periodic)
- Witness notification (polecat done)
- Mayor request (check queue)

## Dependencies

Needs: gt-u1j.6 (mail), gt-u1j.3 (git), gt-u1j.14 (merge queue)

## Reference

See PGT ephemeral.py for branch operations.


implement

Implement the solution for gt-test123. Follow codebase conventions.
File discovered work as new issues with bd create.

Make regular commits with clear messages.
Keep changes focused on the assigned issue.

Depends: load-context


CLI: rig commands (add, list, show, remove)

GGT needs rig management commands.

Missing Commands:
- gt rig add <git-url> [--name NAME] - Add rig to workspace
- gt rig list - List all rigs with status
- gt rig show <rig> - Show detailed rig info
- gt rig remove <rig> - Remove a rig

PGT Reference: gastown-py/src/gastown/cli/rig_cmd.py

Current State:
- gt init creates rig structure but no ongoing management
- Rig discovery in internal/rig/manager.go but not exposed via CLI


Mail system: JSONL inbox, delivery, tmux injection

Refactor mail system to wrap bd mail commands.

## Status

Current implementation uses JSONL files directly. Now that Beads mail is available (gt-r01 closed), refactor to use bd mail as the backend.

## Implementation

Replace internal/mail/* with thin wrappers around bd CLI:

```go
// Send wraps: bd mail send <to> -s <subject> -m <body>
func (r *Router) Send(msg *Message) error

// List wraps: bd mail inbox --json
func (m *Mailbox) List() ([]*Message, error)

// Get wraps: bd mail read <id> --json
func (m *Mailbox) Get(id string) (*Message, error)

// MarkRead wraps: bd mail ack <id>
func (m *Mailbox) MarkRead(id string) error
```

## Address Translation

GGT addresses → Beads recipients:
- `mayor/` → `mayor`
- `<rig>/refinery` → `<rig>-refinery`
- `<rig>/<polecat>` → `<rig>-<polecat>`

## Tmux Notification

Keep the tmux injection for --notify flag. After bd mail send, optionally inject notification into tmux session.

## Migration

No migration needed - bd mail creates messages as beads issues with type=message. Old JSONL inboxes can be ignored or cleaned up.

## Dependencies

- gt-r01: CLOSED (Beads mail available)
- gt-u1j.4: Tmux wrapper (for notifications)


Refinery startup: Use Claude agent instead of foreground mode

WIP found in stash: Refactor refinery startup to spawn Claude as the refinery agent rather than using gt refinery start --foreground.

Changes needed:
- Use refineryDir (refinery/rig) as working directory
- Start Claude with --dangerously-skip-permissions
- Wait for shell ready, then Claude ready
- Send gt prime, then refinery startup prompt
- Remove foreground mode complexity

Related: gt-n7z7 (refinery --foreground race condition bug)


MCP beads tools fail from polecat directories

The beads MCP plugin (plugin:beads:beads) fails to find issues when invoked from polecat directories.

## Observed
- Polecat in /gt/gastown/polecats/dementus
- MCP tool: plugin:beads:beads - show (issue_id: 'gt-th7')
- Error: 'bd command failed: Error: no issue found matching gt-th7'

## Expected
MCP tools should work the same as running bd directly.

## Note
This may be related to gt-tmm (beads sync issue) rather than an MCP-specific bug. The MCP tool uses bd under the hood, and bd can't find the issue because the polecat's beads database is stale.


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.


request-shutdown

Send shutdown request to Witness.
Wait for termination.

The polecat is now ready to be cleaned up.

CLI: core commands (status, prime, version, init)

Essential CLI commands for Gas Town operation.

## Commands

### gt status
Show overall town status.
```
gt status [--json]
```
Output:
- Town name and location
- Number of rigs
- Active polecats across all rigs
- Witness status per rig
- Recent activity summary

### gt prime
Output role context for current directory.
```
gt prime
```
Detects role from directory:
- Town root or mayor/ → Mayor context
- <rig>/witness/rig/ → Witness context
- <rig>/refinery/rig/ → Refinery context
- <rig>/polecats/<name>/ → Polecat context

### gt version
Show version information.
```
gt version [--short]
```
Output: version, git commit, build date.

### gt init
Initialize current rig for Gas Town (alternative to gt install for existing repos).
```
gt init [--force]
```
Creates Gas Town structure in existing git repo.

## Implementation

Each command is a Cobra subcommand under root:
```go
var statusCmd = &cobra.Command{...}
var primeCmd = &cobra.Command{...}
var versionCmd = &cobra.Command{...}
var initCmd = &cobra.Command{...}
```

Register in cmd/gt/main.go.

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 session capture: Support positional line count argument

Make 'gt session capture gastown/Toast 50' work.

Currently requires: gt session capture gastown/Toast -n 50
Should also accept: gt session capture gastown/Toast 50

Agent UX principle: commands should work the way agents guess they work.


implement

Implement the solution for {{issue}}. Follow codebase conventions.
File discovered work as new issues with bd create.

Make regular commits with clear messages.
Keep changes focused on the assigned issue.

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.


Witness Patrol Molecule

Create mol-witness-patrol molecule for witness heartbeat loop.

Similar to DeaconPatrolMolecule but for per-rig witness duties.

## Steps
1. inbox-check - Process witness mail
2. survey-workers - List polecats, check status
3. inspect-workers - Capture pane output, assess state
4. plugin-run - Execute plugins from <rig>/plugins/witness/
5. decide-actions - Determine nudges, escalations
6. execute-actions - Send nudges, process shutdowns
7. context-check - Check own context, handoff if needed
8. loop-or-exit - Continue or cycle

The plugin-run step enables user customization of the patrol loop.


Polecat cleanup should refuse to lose uncommitted work

The system should stubbornly refuse to lose work from a polecat.

## Current Problem

- gt spawn --force bypasses safety checks
- gt shutdown doesn't check for uncommitted work
- Witness cleanup doesn't check git status

## Desired Behavior

Before any polecat cleanup, check:
1. git status - any uncommitted changes?
2. git stash list - any stashes?
3. Unpushed commits on branch?
4. Unsynced beads changes?

If ANY of these exist:
- REFUSE to clean up
- Print clear error message listing what would be lost
- Require explicit --nuclear flag to force (not just --force)

## Implementation

Add to cleanupPolecat() in witness/manager.go:
```go
func (m *Manager) checkUncommittedWork(polecatName string) error {
    dir := m.polecatDir(polecatName)

    // Check git status
    if hasUncommitted, _ := git.HasUncommittedChanges(dir); hasUncommitted {
        return fmt.Errorf("polecat %s has uncommitted changes", polecatName)
    }

    // Check stashes
    if stashCount, _ := git.StashCount(dir); stashCount > 0 {
        return fmt.Errorf("polecat %s has %d stashes", polecatName, stashCount)
    }

    // Check unpushed commits
    if unpushed, _ := git.UnpushedCommits(dir); unpushed > 0 {
        return fmt.Errorf("polecat %s has %d unpushed commits", polecatName, unpushed)
    }

    return nil
}
```

## Affected Commands

- gt shutdown
- gt rig shutdown
- Witness cleanup
- gt spawn --force (should warn if overwriting)


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


Add molecule to update local go binary on push to main

When pushing to main branch, automatically rebuild and install the gt binary on the local machine so changes are immediately available.


Prompt templates: role contexts, nudge messages

Prompt templates for role contexts and messages.

## Template Types

### Role CLAUDE.md Templates

For gt prime and CLAUDE.md generation:
- Mayor template
- Witness template
- Refinery template
- Polecat template

### Message Templates

For notifications and nudges:
- Spawn assignment
- Witness nudge
- Escalation to Mayor
- Session handoff

## Implementation

```go
//go:embed templates/*.md.tmpl
var templateFS embed.FS

type Templates struct {
    fs embed.FS
}

func NewTemplates() *Templates
func (t *Templates) RenderRole(role string, data RoleData) (string, error)
func (t *Templates) RenderMessage(name string, data any) (string, error)
```

## Template Data

```go
type RoleData struct {
    Role      string
    RigName   string
    TownRoot  string
    Polecats  []string
    Commands  []CommandHelp
}

type SpawnData struct {
    Issue       string
    Title       string
    Priority    int
    Description string
}

type NudgeData struct {
    Polecat    string
    Reason     string
    NudgeCount int
    MaxNudges  int
}
```

## Template Location

Embedded in binary via go:embed:
```
internal/templates/
├── roles/
│   ├── mayor.md.tmpl
│   ├── witness.md.tmpl
│   ├── refinery.md.tmpl
│   └── polecat.md.tmpl
└── messages/
    ├── spawn.md.tmpl
    ├── nudge.md.tmpl
    └── escalation.md.tmpl
```

## Usage

gt prime uses role templates.
gt spawn uses spawn template.
Witness uses nudge/escalation templates.


Error handling improvements: retry logic and recovery hints

Improve error handling across GGT codebase.

## Issues Found

### 1. Silent Failures in Refinery
manager.go ProcessMR():
- git pull errors ignored
- Continues processing even on partial failures

### 2. Missing Beads CLI
Many operations silently continue if `bd` not found:
```go
// Current
tasks, err := m.loadTasksFromBeads(epicID)
if err != nil {
    // Non-fatal - swarm can start without tasks
}

// Better
if err != nil {
    return nil, fmt.Errorf("beads required: %w", err)
}
```

### 3. No Retry Logic
Network/lock errors should retry:
```go
func withRetry(attempts int, delay time.Duration, fn func() error) error {
    for i := 0; i < attempts; i++ {
        if err := fn(); err == nil {
            return nil
        }
        time.Sleep(delay)
    }
    return fmt.Errorf("failed after %d attempts", attempts)
}
```

### 4. Recovery Hints
Error messages should include fix suggestions:
```go
// Current
return fmt.Errorf("polecat not found")

// Better
return fmt.Errorf("polecat '%s' not found. Use 'gt polecat list' to see available polecats", name)
```

## Domain Error Types
```go
type SessionError struct {
    Op      string
    Polecat string
    Err     error
}

func (e *SessionError) Error() string {
    return fmt.Sprintf("session %s for %s: %v", e.Op, e.Polecat, e.Err)
}
```

## Files to Review
- internal/refinery/manager.go
- internal/swarm/manager.go
- internal/session/manager.go
- All cmd/*.go files

## Acceptance Criteria
- [ ] No silent error swallowing
- [ ] Retry logic for transient failures
- [ ] Helpful error messages with hints
- [ ] Consistent error types per domain


Inconsistent error wrapping patterns

Error handling is inconsistent across the codebase:

1. Some functions use fmt.Errorf with %w for wrapping, others don't
2. return nil, nil patterns (40+ occurrences) sometimes represent 'not found' and sometimes 'error but continue' - should use sentinel errors
3. Some places return nil for errors when they should propagate them

Examples of nil,nil that might need review:
- internal/git/git.go:272, 308
- internal/crew/manager.go:227
- internal/witness/manager.go:517, 523, 530, 775
- internal/beads/beads.go:225, 492


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)

Reference: docs/merge-queue-design.md#integration-branches


gt handoff: Deadlock bug in runHandoff

Running 'gt handoff' from a polecat causes a deadlock:

Stack trace shows:
- goroutine 1 [select (no cases)] in runHandoff
- File: internal/cmd/handoff.go:125

The command successfully sends the shutdown request but then hangs with 'fatal error: all goroutines are asleep - deadlock!'

gt rig reset --stale: Clear orphaned in_progress items

Reset in_progress issues when their assigned agent no longer exists.

## Problem
When polecats die without cleanup, their issues remain in_progress forever.
Need a way to bulk-reset these orphaned items.

## Command
```bash
gt rig reset --stale [--dry-run]
```

## Logic
For each in_progress issue in rig:
1. Parse assignee (e.g., "gastown/furiosa")
2. Map to tmux session name (gt-gastown-furiosa)
3. If session does NOT exist:
   - Reset status to "open"
   - Clear assignee
4. Exception: skip crew/* assignees (persistent identities)
   OR check if crew tmux session exists

## Output
```
Resetting stale work in gastown:
  gt-abc: gastown/furiosa (no session) → open
  gt-def: gastown/nux (no session) → open
  Skipped: gt-xyz: gastown/crew/max (persistent)
Reset 2 issues, skipped 1
```

Fetch and conflict check: git operations for MR

Implement git operations for MR processing.

Steps:
1. git fetch origin <mr.branch>
2. git checkout <mr.target> (main or integration/xxx)
3. git merge --no-commit --no-ff <mr.branch> (test merge)
4. Check for conflicts
5. If conflicts: abort and return Failure(conflict, files)
6. If clean: abort (actual merge in next step)

Helper functions:
- FetchBranch(branch string) error
- CheckConflicts(source, target string) ([]string, error)

gt molecule seed: create built-in molecules as beads

The molecule infrastructure is complete but built-in molecules (engineer-in-box, quick-fix, research) need to be seeded into the beads database.

## Current State
- `gt molecule list` works but shows 0 molecules
- BuiltinMolecules() in internal/beads/builtin_molecules.go has 3 molecules defined
- No way to create them as beads

## Needed
Add `gt molecule seed` command that:
1. Reads BuiltinMolecules()
2. Creates each as a bead with type: molecule
3. Uses well-known IDs (mol-engineer-in-box, mol-quick-fix, mol-research)
4. Idempotent (skip if already exists)

## Acceptance Criteria
```
gt molecule seed
gt molecule list   # Shows 3 built-in molecules
```

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.)


BUG: gt done doesn't push branch to origin - work lost when worktree deleted

## Problem

`gt done` creates a merge-request record in beads but **never pushes the branch to origin**.

When polecats are cleaned up (worktrees deleted), the branch is lost forever. The MR record exists but there's no actual branch to merge.

## Evidence

12 MQ items had `ready` status but no corresponding branches on origin. All polecat worktrees were deleted, losing all work.

## Impact

**CRITICAL**: All polecat work is silently lost unless polecats manually push (which they don't know to do).

## Fix

In `done.go`, before creating the MR:
1. `git push origin <branch>` to push the branch to remote
2. Only create MR record if push succeeds

## Location
`mayor/rig/internal/cmd/done.go:124-135`
