Molecule converge: iterate until AI says done

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

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

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

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

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

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


Default polecat names: Mad Max theme instead of AdjectiveNoun

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

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

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

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


Success handling: close MR, close source issue, cleanup

Handle successful merge completion.

Steps:
1. Update MR with merge_commit SHA:
   bd update <id> --body='...\nmerge_commit: <sha>'
2. Close MR with reason:
   bd close <id> --reason='merged'
3. Close source issue (the work item):
   bd close <source_issue> --reason='Merged in <mr_id>'
4. Delete source branch (if configured):
   git push origin --delete <mr.branch>
5. Log success

Configuration:
- delete_merged_branches: bool (default true)

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


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


Recover stale polecat work: 4 branches with unpushed commits

During observation of polecat workflow, found 4 polecats with unpushed work:

## Branches Pushed (preserved)
- polecat/capable: 3 commits (molecule catalog, doctor orphan detection, gt done)
- polecat/dementus: 4 commits (Witness MVP, handoff fixes)
- polecat/furiosa: 2 commits (bulk polecat removal, spawn handoff)
- polecat/rictus: 1 commit (molecule docs)

## Action Required
1. Review each branch for merge-worthiness
2. Either:
   a. Create PRs for valuable work
   b. OR discard if superseded
3. After decision, clean up polecats properly

## Root Cause
Polecats were not cleaned up after previous work sessions. This is exactly why we need:
- gt-u1k: gt shutdown should fully cleanup polecats
- gt-8v8: Refuse to lose uncommitted work
- gt-9nf: Always create fresh polecats

Test patrol cycle - verifying wisp flow


Phase 1.3: gt doctor checks for ephemeral health

Add doctor checks for ephemeral beads repo.

## Checks

1. **ephemeral-exists**: .beads-ephemeral/ directory exists for each rig
2. **ephemeral-git**: It's a valid git repo
3. **ephemeral-orphans**: Molecules started but never squashed (>24h old)
4. **ephemeral-size**: Warn if ephemeral repo is >100MB (should be cleaned)
5. **ephemeral-stale**: Molecules with no activity in last hour

## Auto-fix

--fix can:
- Create missing ephemeral repo
- Clean up old completed molecules (already squashed)
- NOT auto-squash incomplete molecules (needs AI summary)


gt crew remove: Remove crew workspace

Implement 'gt crew remove <name> [--force]' command:
- Check for uncommitted changes, unpushed commits
- Warn and require --force if dirty
- Kill any running session
- Remove directory
- Unregister from mail


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


Swarm: report generation

Generate markdown reports for completed swarms.

## Command
```
gt swarm report <swarm-id> [--save <file>]
```

## Report Content

### Header
- Swarm ID and title
- Created/completed timestamps
- Duration
- Rig name

### Task Summary
| Task | Assignee | Status | Duration |
|------|----------|--------|----------|
| gt-xxx | Toast | merged | 15m |
| gt-yyy | Nux | merged | 22m |

### Worker Contributions
- Commits per worker
- Issues closed per worker
- Lines changed (optional)

### Timeline
- Chronological events from events.jsonl
- Key milestones (started, first merge, landing)

### Issues Encountered
- Conflicts resolved
- Failed tasks (if any)
- Escalations

## Implementation
```go
func GenerateReport(swarmID string) (*SwarmReport, error)
func (r *SwarmReport) ToMarkdown() string
```

## Storage
- Save to <rig>/.gastown/swarms/<id>/report.md
- Or user-specified path with --save

## PGT Reference
gastown-py/src/gastown/swarm/manager.py generate_report()

## Acceptance Criteria
- [ ] Markdown report generated
- [ ] Includes all sections above
- [ ] Auto-saved to swarm directory
- [ ] --save allows custom path


gt rig info: Show detailed rig information

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

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


Beads CLI wrapper: shell out to bd

Wrapper for bd (beads CLI) commands.

## Interface

```go
type Beads struct {
    workDir string
}

func NewBeads(workDir string) *Beads

// Query
func (b *Beads) List(opts ListOptions) ([]*Issue, error)
func (b *Beads) Ready() ([]*Issue, error)
func (b *Beads) Show(id string) (*Issue, error)
func (b *Beads) Blocked() ([]*Issue, error)

// Mutations
func (b *Beads) Create(opts CreateOptions) (*Issue, error)
func (b *Beads) Update(id string, opts UpdateOptions) error
func (b *Beads) Close(ids ...string) error

// Sync
func (b *Beads) Sync() error
func (b *Beads) SyncStatus() (*SyncStatus, error)
```

## Data Types

```go
type Issue struct {
    ID          string
    Title       string
    Status      string
    Priority    int
    Type        string
    Description string
    Parent      string
    Children    []string
    DependsOn   []string
    Blocks      []string
}

type ListOptions struct {
    Status   string  // "open", "closed", "all"
    Type     string
    Priority int
}

type CreateOptions struct {
    Title       string
    Type        string
    Priority    int
    Description string
    Parent      string
}
```

## Implementation

Shell out to bd binary, parse JSON output where available.
```go
func (b *Beads) runBd(args ...string) ([]byte, error) {
    cmd := exec.Command("bd", args...)
    cmd.Dir = b.workDir
    return cmd.Output()
}
```

## Error Handling

- bd not installed: Clear error with install instructions
- Not a beads repo: Detect and report
- Sync conflicts: Parse and report


Beads as Universal Data Plane

## Vision

Beads is the data plane for all Gas Town operations. Everything flows through beads:
- Work items (issues, tasks, epics)
- Mail (messages between agents)
- Merge requests (queue entries)
- Workflows (composable execution patterns)
- Resources (leases, locks, quotas)
- Schedules (timed activities)

## New Bead Categories

### Molecules (Composable Workflows)
Crystallized workflow patterns that can be attached to work items.

### Timed Beads (Scheduled Work)
Beads that wake up periodically via daemon.

### Pinned Beads (Ongoing Concerns)
Beads representing persistent concerns, not discrete tasks.

### Resource Beads (Leases/Locks)
Beads representing reserved resources.

## v1 Priority

- **P0**: Molecules (enables engineer-in-box)
- **P2**: Timed, Pinned, Resource beads (post-v1)


HOP: Entity chain tracking for agents

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


Split PGT/GGT harness or migrate to GGT-only

Current ~/ai harness is shared by PGT and GGT with confusing overlap. Options:
1. Keep separate (document the coexistence)
2. Migrate fully to GGT structure
3. Create separate harnesses

This affects the beads redirect, Mayor home location, and rig structure.


gt spawn/crew setup should create .beads/redirect for worktrees

Crew clones and polecats need a .beads/redirect file pointing to the shared beads database (../../mayor/rig/.beads). Currently:

- redirect files can get deleted by git clean
- not auto-created during gt spawn or worktree setup
- missing redirects cause 'no beads database found' errors

Found missing in: gastown/joe, beads/zoey (after git clean)

Fix options:
1. gt spawn creates redirect during worktree setup
2. gt prime regenerates missing redirects
3. bd commands auto-detect worktree and find shared beads

This should be standard Gas Town rig configuration.


gt handoff: Deadlock in waitForRetirement


gt prime should detect mayor role from any rig's mayor/ folder

Currently gt prime only detects the Mayor role when run from town root (~/gt). It should also detect Mayor when run from:
- ~/gt/gastown/mayor/rig (rig's internal mayor dir)
- Any path containing /mayor/ under a rig

This would allow the mayor session to work correctly regardless of which rig directory it's attached to.


CLI: mail commands (send, inbox, read)

CLI: mail commands wrapping bd mail.

## Status

Current implementation works with JSONL files. Refactor to wrap bd mail CLI.

## Commands

### gt mail inbox
```
gt mail inbox [--unread] [--json]
```
Wraps: `bd mail inbox [--json]`

### gt mail read
```
gt mail read <id>
```
Wraps: `bd mail read <id> && bd mail ack <id>`
Note: bd mail read + ack marks as read.

### gt mail send
```
gt mail send <address> -s "Subject" -m "Body" [--notify]
```
Wraps: `bd mail send <recipient> -s "Subject" -m "Body"`
If --notify: inject tmux notification after send.

### gt mail delete
```
gt mail delete <id>
```
Wraps: `bd mail ack <id>` (closes the message issue)

## Address Translation

Same as gt-u1j.6:
- `mayor/` → `mayor`
- `<rig>/refinery` → `<rig>-refinery`
- `<rig>/<polecat>` → `<rig>-<polecat>`

## Dependencies

- gt-u1j.6: Mail system backend


Architecture: beads config and direct landing docs

Added to architecture.md:
- Beads multi-agent configuration table (daemon, worktree, sync-branch)
- ASCII directory layout for non-mermaid rendering
- Direct landing workflow (bypass merge queue)
- Design decisions 9 and 10 for direct landing and daemon awareness
- CLI commands for gt land


Design: Swarm shutdown and worker cleanup

Design for graceful swarm shutdown, worker cleanup, and session cycling.

## Key Decisions

1. Pre-kill verification uses model intelligence (not framework rules)
2. Witness can request restart when context filling (mail self, exit)
3. Mayor NOT involved in per-worker cleanup (Witness responsibility)
4. Clear responsibility boundaries between Mayor/Witness/Polecat

## Subtasks (implementation)

- gt-sd6: Polecat decommission checklist prompting
- gt-f8v: Witness pre-kill verification protocol
- gt-eu9: Witness session cycling and handoff
- gt-gl2: Mayor vs Witness cleanup responsibilities

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


Merge conflicts: Buzzard/mq-status, Dementus/harness-docs


Add Deacon heartbeat mechanism

Deacon writes deacon/heartbeat.json on each wake. Go daemon reads it to decide whether to poke. Add heartbeat read/write helpers.


gt witness: Witness management commands

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

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

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


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


Design: Polecat Beads write access

Design for granting polecats direct beads write access.

## Background

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

## Benefits

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

## Complications

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

## Subtasks (implementation)

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

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


Test Task 2: Add comment to version.go


Document Overseer role (human operator)

Document the Overseer role in Gas Town architecture.

## The Overseer

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

## Responsibilities

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

## Key Interactions

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

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

## Operating Cadence

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

## Commands for Overseers

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

## Documentation Updates

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

Work on gt-e11: gt mail send priority flag is incompatible with bd mail send. Run 'bd show gt-e11' for details.


Design: Additional design issues (placeholder)

Placeholder for additional design issues the user wants to raise and work through. Convert to specific subtasks as issues are identified.


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`


Deacon event/timer callbacks: reactive triggers

Implement event-triggered and timer-based callbacks in the Deacon.

## Timer Callbacks

Agents can schedule future wakes by mailing the Deacon:
```
Subject: TIMER: gastown/witness wake at 2025-12-20T16:00:00Z
Body: Please nudge me - I'm waiting for external dependency
```

Deacon processing:
1. Parse timer mail
2. Check if time has passed
3. If yes: mail the agent "WAKE: Timer fired"
4. Close the timer mail

## Event Subscriptions

Plugins/agents can subscribe to events:
```yaml
# In kernel bead or plugin config
event_triggers:
  - event: "issue.created"
    action: mail
    target: "plugins/work-oracle"

  - event: "mr.submitted"
    action: run
    plugin: "review-oracle"

  - event: "agent.stuck"
    action: escalate
    target: human
```

## Event Sources

Events come through mail to deacon/:
```
Subject: EVENT: issue.created gt-abc123
Body: New issue created in gastown rig
```

## Event Types

Initial event types:
- `issue.created` - New bead created
- `issue.closed` - Bead closed
- `mr.submitted` - Merge request submitted
- `mr.merged` - Merge request merged
- `agent.stuck` - Agent appears stuck (from health scan)
- `agent.failed` - Agent remediation failed

## Event Processing

During events step:
1. Read event mail from inbox
2. Match against subscriptions
3. Execute actions:
   - `mail`: Send mail to target
   - `run`: Execute plugin inline
   - `spawn`: Spawn subagent for plugin
   - `escalate`: Mail human

## Relation to Mail

Mail IS the event bus. No separate event system.
Events are just specially-formatted mail to deacon/.


Test: Alpha to Beta

Sibling communication test


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


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.


Crew worker CLAUDE.md prompting

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


Consolidate design docs into beads descriptions

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


MVP Cutover: GGT replaces PGT for batch work

When this is closed, stop using town and start using gt.

## Acceptance Criteria

1. gt spawn assigns issue to polecat and starts session
2. gt spawn --epic spawns workers for all epic children
3. gt session manages tmux lifecycle
4. gt send / gt inbox work for mail
5. Refinery processes merge queue with semantic merges
6. Integration branches created and landed correctly
7. gt stop --all halts all sessions
8. One successful test batch completed end-to-end

## What Must Work

- Spawn polecat with issue assignment
- Spawn workers for epic children
- Session start/stop/attach
- Mail send/inbox/read
- Refinery merge loop (semantic)
- Integration branch → main landing
- Witness cleanup protocol
- Emergency stop

## What Can Be Deferred

- Doctor checks (use PGT)
- TUI dashboard
- Plugin system
- Federation
- Ephemeral rigs
- Detailed landing reports

## Test Plan

1. Create epic with 2 tasks, spawn 2 workers
2. Verify polecats get assigned and sessions start
3. Simulate task completion
4. Verify Refinery merges to integration
5. Verify landing to main
6. Verify cleanup

## Validation

Run one real batch implementing GGT issues using GGT.

## Note

No "swarm IDs" - just spawn workers for epic, let merge queue coordinate.


Daemon heartbeat: worker and queue monitoring

Daemon periodic checks for work progress.

## Heartbeat Actions

Every N seconds (configurable):

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

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

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

## Eventually Convergent

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

Even if one signal missed, system converges.

## Interface

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

## Notifications

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


Refactor: Eliminate state.json, use beads assignee field for polecat state

## Problem

state.json in each polecat worktree duplicates data that should be in beads:
- `issue` field duplicates assignment (should be issue.assignee)
- `state` field duplicates status (derivable from issue.status)
- `name/rig/branch/clone_path` are all derivable from filesystem/git

This violates 'Beads as the data plane' (HOP Decision 001).

## Current State

```json
{
  "name": "Angharad",        // Derivable: basename(cwd)
  "rig": "gastown",          // Derivable: parent dir name
  "state": "working",        // Should be: issue.status
  "clone_path": "/path",     // Derivable: cwd
  "branch": "polecat/X",     // Derivable: git branch
  "issue": "gt-xyz",         // Should be: issue.assignee
  "timestamps": "..."        // Should be in beads history
}
```

## Target State

**Polecat identity**: Derived from worktree path
**Polecat assignment**: `issue.assignee = 'gastown/Angharad'`
**Polecat state**: Derived from issue.status (in_progress = working, closed = done)
**Polecat existence**: Worktree directory exists

## Benefits

1. Single source of truth (no sync issues)
2. Queryable: `bd list --assignee=gastown/Angharad`
3. History tracking via beads
4. Cross-agent coordination via beads sync
5. Simpler code (no state file management)

## Implementation

1. Update `gt spawn` to set issue.assignee instead of writing state.json
2. Update polecat list/status commands to query beads
3. Update Witness to query beads for polecat state
4. Remove state.json read/write code
5. Keep state.json as optional bootstrap cache (perf optimization only)


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


MR: gt-test (main)

branch: main
target: main
source_issue: gt-test


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.


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)

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


Molecule CLI: bd molecule commands

Add molecule commands to bd:

## Commands

```bash
bd molecule list              # List molecules (type: molecule)
bd molecule show <id>         # Show molecule with parsed steps
bd molecule parse <id>        # Validate and show parsed structure
bd molecule instantiate <mol-id> --parent=<issue-id>  # Create steps
bd molecule instances <mol-id>  # Show all instantiations
```

## gt spawn integration

```bash
gt spawn --issue <id> --molecule <mol-id>
```

This should:
1. Call `bd molecule instantiate` (creates child beads atomically)
2. Spawn polecat on first ready step
3. Polecat grinds through via `bd ready`

## Output Examples

```
$ bd molecule show mol-abc

mol-abc: Engineer in a Box
Type: molecule

Steps (5):
  design      → (ready first)
  implement   → Needs: design
  review      → Needs: implement
  test        → Needs: implement
  submit      → Needs: review, test

Instances: 3
```

```
$ bd molecule instances mol-abc

Parent          Status    Created
gt-xyz          done      2025-12-15
gt-abc          active    2025-12-17 (3/5 complete)
gt-def          pending   2025-12-18
```

Step recovery: timeout and release

Implement recovery mechanism for stuck molecule steps.

## Problem
When a worker dies mid-step, the step stays in_progress forever.
Need timeout/release mechanism for nondeterministic idempotence.

## Solution
1. Track step start time (claimed_at timestamp)
2. Timeout: After 30 min in_progress, step returns to pending
3. Manual release: bd release <step-id>

## Implementation Options

### Option A: Beads-level timeout
- Add claimed_at field to issues
- bd ready excludes items in_progress < 30 min
- bd ready includes items in_progress > 30 min (auto-recovery)

### Option B: Daemon-level timeout
- Daemon watches in_progress items
- Moves back to pending after timeout

### Option C: Manual only (MVP)
- bd release <id> manually moves in_progress → pending
- Document recovery procedure
- Witness can automate for polecats

## Recommendation
Start with Option C (manual) for Christmas. Add Option A later.

## Acceptance
- [ ] bd release command works
- [ ] Stuck steps can be recovered
- [ ] Documented recovery procedure

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


CLI: cleanup commands for stale state

Cleanup commands for recovering from stale state.

## Commands

### gt cleanup <polecat>
Clean stale state for specific polecat.
```
gt cleanup <rig>/<polecat> [--dry-run]
```

Actions:
- Remove orphaned state.json if clone missing
- Clear stale session references
- Reset stuck state (working → idle after timeout)

### gt cleanup --all
Clean all polecats in workspace.
```
gt cleanup --all [--dry-run]
```

## Implementation
```go
func CleanupPolecat(rigName, polecatName string, dryRun bool) (*CleanupResult, error)

type CleanupResult struct {
    OrphanedStateRemoved bool
    SessionsCleared      int
    StateReset           bool
    Warnings             []string
}
```

## Overlap with Doctor
- Doctor diagnoses and offers --fix
- Cleanup is more aggressive state recovery
- Consider merging into doctor --fix

## New File
internal/cmd/cleanup.go

## Acceptance Criteria
- [ ] Removes orphaned state files
- [ ] Clears stale session refs
- [ ] --dry-run shows what would happen
- [ ] Reports all actions taken

Swarm learning: Beads database locality gap

## PGT Bug (GGT Design Already Correct)

Mayor created issues in `~/ai/mayor/rigs/beads/.beads/` but polecats use `~/ai/beads/.beads/`. Different databases = polecats can't see Mayor's beads.

**GGT Fix**: architecture.md already specifies:
- All agents use BEADS_DIR pointing to rig-level `.beads/`
- Lines 116-143: Beads Configuration for Multi-Agent
- Lines 573-586: Rig-Level Beads via BEADS_DIR

This is a PGT implementation gap, not a design issue. GGT spawn must set BEADS_DIR correctly.

Rig management: discover, load, create rigs

Rig discovery, loading, and creation.

## Interface

```go
type Rig struct {
    Name      string
    Path      string
    GitURL    string
    Config    RigConfig
    Polecats  []string
    HasWitness bool
    HasRefinery bool
}

type RigManager struct {
    townRoot string
    config   *Config
    git      *Git
}

func NewRigManager(townRoot string, config *Config, git *Git) *RigManager

// Discovery
func (rm *RigManager) DiscoverRigs() ([]*Rig, error)
func (rm *RigManager) GetRig(name string) (*Rig, error)
func (rm *RigManager) RigExists(name string) bool

// Creation
func (rm *RigManager) AddRig(name, gitURL string) (*Rig, error)
func (rm *RigManager) RemoveRig(name string) error

// Rig state
func (rm *RigManager) LoadRigConfig(rig *Rig) error
func (rm *RigManager) SaveRigConfig(rig *Rig) error
```

## Discovery Logic

1. Read rigs.json from config/
2. For each registered rig, verify directory exists
3. Load rig-level config if present
4. Scan for polecats/ subdirectory
5. Check for witness/, refinery/ directories

## Rig Creation

1. Clone repo to town root
2. Add entry to rigs.json
3. Create agent directories (polecats/, witness/, refinery/, mayor/)
4. Update .git/info/exclude to ignore agent dirs
5. Initialize rig config

## Rig Structure

Per docs/architecture.md:
```
<rig>/
├── polecats/
├── refinery/rig/
├── witness/rig/
└── mayor/rig/
```


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-test - The source issue ID being worked on


gt crew restart command

Add a 'gt crew restart' command that kills the tmux session and restarts fresh. Useful when a crew member gets confused or needs a clean slate.

Should:
- Kill existing tmux session if running
- Start fresh session with claude
- Run gt prime to reinitialize context

Alias: gt crew rs


Haiku-based smart stuck detection

Use Haiku to analyze tmux state when signals are ambiguous.

## When to Invoke

Only as escalation tier:
1. Keepalive is stale (> 2 min)
2. Tmux shows claude is running (not idle shell)
3. Heuristics can't determine state

## Prompt

Capture last 50 lines of tmux pane, ask Haiku:
'Is this Claude agent: WORKING | STUCK | IDLE | WAITING_FOR_HUMAN?'

## Cost

~$0.001 per check. At 1 check/min worst case = $0.06/hour.
In practice, most checks avoided by keepalive signal.

## Configuration

```toml
[daemon]
smart_detection = true
smart_model = "haiku"
smart_threshold = "2m"  # only check if stale > 2min
```

Human escalation: notify overseer when self-heal fails

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

**Implementation**: Config in town.json or similar:
```yaml
escalation:
  contact: steve@example.com  # or slack webhook
  triggers:
    - daemon_cant_restart
    - session_missing_5min
```

**Trigger points**:
- Go daemon can't restart a session after N attempts
- Agent detects it's stuck and can't recover
- Witness can't reach polecat

**Mechanism**:
- Simple: `gt mail send --human` already exists
- Enhanced: email/slack via external script

**Weight**: Small config + one code path in daemon
**Value**: High for unattended operation - human gets notified instead of silent failure


Polecat mood command and status line display

CLI and status line support for polecat mood.

## CLI Command
```
gt polecat mood <name> <emoji>   # Set mood
gt polecat mood <name>           # Get mood
```

Sets GT_MOOD environment variable in the polecat's tmux session.

## Status Line Integration
Update runWorkerStatusLine() to read mood:
```go
mood, _ := t.GetEnvironment(session, "GT_MOOD")
if mood != "" {
    icon = mood  // Use mood emoji instead of default
} else {
    icon = AgentTypeIcons[AgentPolecat]  // Fallback to 😺
}
```

## Storage
Mood stored in tmux session environment (ephemeral, per-session).
No persistence needed - mood is reassessed each patrol cycle.

Depends on: gt-u818 (plugin system)


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


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


Auto-rebase on conflict: optional automatic rebase

Implement automatic rebase as conflict resolution option.

When on_conflict=auto_rebase and conflicts detected:
1. Attempt: git rebase <target> <source-branch>
2. If clean rebase: update source branch, continue merge
3. If conflicts in rebase: abort, fall back to assign_back
4. Force push rebased branch (worker's branch)

Requires:
- Worker branch must be force-pushable
- Config: on_conflict: auto_rebase

Risks:
- Force push can confuse workers
- Complex conflicts still need manual resolution

Reference: docs/merge-queue-design.md#conflict-resolution-strategies


Refinery Engineer: Role prompting and CLAUDE.md

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

Phase 5.1: Document ephemeral architecture

Update docs with ephemeral molecule architecture.

## Files to Update

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

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

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

## Key Concepts to Document

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


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.


Worker cleanup: Beads sync on shutdown

Add beads sync verification to worker cleanup checklist and Witness verification.

## Update to Decommission Checklist (gt-sd6)

Add to pre-done verification:
- bd sync --status must show 'Up to date'
- git status .beads/ must show no changes

## Beads Edge Cases

Uncommitted beads changes:
  bd sync
  git add .beads/
  git commit -m 'beads: final sync'

Beads sync conflict (rare):
  git fetch origin main
  git checkout main -- .beads/
  bd sync --force
  git add .beads/
  git commit -m 'beads: resolve sync conflict'

## Update to Witness Verification (gt-f8v)

When capturing worker state:
  town capture <polecat> "bd sync --status && git status .beads/"

Check for:
- bd sync --status shows 'Up to date'
- git status .beads/ shows no changes

If beads not synced, nudge:
  WITNESS CHECK: Beads not synced. Run 'bd sync' then commit .beads/. Signal done when complete.


gt spawn beads sync warning is misleading for redirect-based polecats

## Problem

When spawning a polecat, gt spawn shows a warning:
```
Warning: beads sync: exit status 1
```

This is misleading because polecats using the redirect architecture (`.beads/redirect`) share the canonical database at `mayor/rig/.beads/beads.db`. The 'stale beads' indicated by the warning is just git branch divergence (main vs beads-sync), not actual data staleness.

## Expected Behavior

gt spawn should either:
1. Skip the beads sync check for polecats using redirects (they share the canonical DB)
2. Or provide a clearer message like 'beads redirect active, using shared database'

## Reproduction

```bash
gt spawn --issue gt-xxx --rig gastown --create
# Shows 'Warning: beads sync: exit status 1' even though beads are current
```

## Root Cause

spawn.go calls beads sync and treats any non-zero exit as a warning. But with redirects, the polecat doesn't need its own beads - it uses the canonical source via the redirect chain:
```
polecat/.beads/redirect -> ../../.beads -> gastown/.beads/redirect -> mayor/rig/.beads
```

## Fix Options

1. Check for .beads/redirect before calling sync
2. Have bd sync return 0 when redirect is present
3. Suppress the warning in spawn when redirect exists


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)


Town-level beads: Real DB for coordination mail

Implement Option A from mail redesign: Town gets real beads DB for coordination.

## Background

Mail is now Beads. But currently:
- Town .beads/redirect points to rig beads
- mayor/mail/ has legacy JSONL files
- Cross-rig coordination has no clear home

## Design

Town beads = coordination, cross-rig mail, mayor inbox, handoffs
Rig beads = project issues, work items

Matches HOP hierarchy: platform > project > worker

## Structure

~/gt/
  .beads/           # REAL beads DB (prefix: gm-)
  mayor/
    town.json
    state.json      # NO mail/ directory
  gastown/
    .beads/         # Rig beads (prefix: ga-)

## Tasks

1. Delete ~/gt/.beads/redirect
2. Run bd init --prefix gm at ~/gt/ (town beads)
3. Delete ~/gt/mayor/mail/ directory
4. Update gt mail to use beads not JSONL
5. Add mail fields (thread_id, reply_to, msg_type)
6. Update gt prime for two-tier model
7. Update docs/architecture.md

## Addressing

- mayor/ -> town beads
- rig/agent -> rig beads
- Cross-rig -> town beads


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.


gt refinery attach: Attach to refinery session

Add 'gt refinery attach [rig]' command to attach to refinery tmux session.

Mirrors 'gt mayor attach' pattern. If rig not specified, use current rig context.


Deacon plugin scheduler: cron-like execution

Implement scheduled plugin execution in the Deacon's plugins step.

## Concept

Plugins are just directories with config. Deacon checks which are due
and executes them during the plugins step of rounds.

## Plugin Registration

Plugins are registered in:
1. Pinned kernel bead (preferred)
2. `{townRoot}/plugins/` directory scan (fallback)

Each plugin has:
```json
{
  "name": "beads-hygiene",
  "schedule": "0 2 * * *",
  "last_run": "2025-12-20T02:00:00Z",
  "enabled": true,
  "attention_budget": "low",
  "max_duration_minutes": 30
}
```

## Schedule Format

Standard cron format: `minute hour day month weekday`
- `0 2 * * *` - 2 AM daily
- `0 4 * * 0` - 4 AM Sundays
- `*/15 * * * *` - Every 15 minutes

## Execution

During plugins step:
1. Load plugin schedules from kernel bead + directory
2. For each plugin:
   a. Parse schedule, check if due (last_run + schedule)
   b. If due, execute:
      - Read `plugins/{name}/CLAUDE.md` for context
      - Run plugin logic (inline or spawn subagent)
      - Record outcome and update last_run
3. Continue to next step

## Plugin Execution Modes

- **inline**: Deacon runs the plugin logic directly (simple, fast)
- **subagent**: Spawn a polecat-like agent for the plugin (complex, parallel)
- **mail**: Send mail to another agent to do the work (delegation)

## State Tracking

`{townRoot}/deacon/plugin-state.json`:
```json
{
  "plugins": {
    "beads-hygiene": {
      "last_run": "2025-12-20T02:00:00Z",
      "last_outcome": "success",
      "run_count": 42,
      "failure_count": 2
    }
  }
}
```

## Relation to gt-axz

This implements the execution side of the plugin architecture (gt-axz).
gt-axz defines the format; this task implements the scheduler.

Phase 1.2: Configure bd for ephemeral molecule bonding

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

## Questions for Dave

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

## Integration

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

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


Merge: gt-92l

branch: polecat/Ace
target: main
source_issue: gt-92l
rig: gastown


Bug: LIFECYCLE messages use literal <rig> placeholder

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

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

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


LocalOutpost: Refactor current polecat spawning

## Overview

Refactor current local polecat spawning to implement the Outpost interface.

## Current State

Polecat spawning is ad-hoc. This task wraps it in LocalOutpost.

## Implementation

```go
type LocalOutpost struct {
    name       string
    maxWorkers int
    tmux       *Tmux
    workers    map[string]*LocalWorker
}

func NewLocalOutpost(config OutpostConfig) *LocalOutpost

func (o *LocalOutpost) Type() OutpostType { return OutpostLocal }

func (o *LocalOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    // Create tmux session
    // Start claude in pane
    // Return LocalWorker
}
```

## LocalWorker

```go
type LocalWorker struct {
    id      string
    session string  // tmux session name
    issue   string
    status  WorkerStatus
}

func (w *LocalWorker) Attach() error {
    // tmux attach-session
}
```

## Notes

- This should be a refactor, not new functionality
- Existing polecat code becomes LocalOutpost internals
- Tests should pass before and after

Depends on: gt-9a2.1 (interfaces)


Batch work landing report generation

Generate reports on batch work completion.

## Trigger

When all children of an epic are closed, generate a completion report.

## Report Contents

- Epic metadata (ID, title, created by, duration)
- Task summary (completed counts, timing)
- Per-task details (issue, assignee, time taken)
- Git stats (commits merged, lines changed)
- Cleanup stats (branches deleted)

## Output Locations

1. Mail to Mayor - summary report
2. Optional: save to file with --save flag

## Command

```bash
gt report --epic <epic-id> [--save report.md]
```

## Format

Markdown with sections:
- Summary
- Tasks
- Workers
- Timeline

## Note

This replaces the swarm-based reporting (gt-662). Reports are generated from epic/issue data, not from separate swarm state files.

## Reference

PGT: swarm/report.py (for format ideas, ignore swarm ID patterns)


Design: Swarm shutdown and worker cleanup

Design for graceful swarm shutdown, worker cleanup, and session cycling.

## Key Decisions

1. Pre-kill verification uses model intelligence (not framework rules)
2. Witness can request restart when context filling (mail self, exit)
3. Mayor NOT involved in per-worker cleanup (Witness responsibility)
4. Clear responsibility boundaries between Mayor/Witness/Polecat

## Subtasks (implementation)

- gt-sd6: Polecat decommission checklist prompting
- gt-f8v: Witness pre-kill verification protocol
- gt-eu9: Witness session cycling and handoff
- gt-gl2: Mayor vs Witness cleanup responsibilities

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


Fix golangci-lint errcheck warnings (~160 issues)

Running golangci-lint shows ~160 errcheck warnings for unchecked error returns.

Common patterns:
- t.SetEnvironment() return values
- os.WriteFile(), os.RemoveAll()
- MarkFlagRequired() on cobra commands
- Various manager methods

Run: golangci-lint run ./...

Could batch fix with:
1. Add explicit _ = for intentionally ignored errors
2. Handle errors properly where they matter
3. Consider adding //nolint:errcheck for cobra flag setup

        "https://%s-%s.a.run.app",
        cfg.Service, cfg.Region,
    )
    return &CloudRunOutpost{

## Spawn

```go
func (o *CloudRunOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    req := WorkRequest{
        IssueID: issue,
        Rig:     RigConfig{URL: cfg.RigURL, Branch: cfg.GitBranch},
        Beads:   BeadsConfig{URL: cfg.BeadsURL, Branch: "beads-sync"},
        Branch:  "polecat/" + issue,
    }

    events, err := o.client.DispatchWork(context.Background(), req)
    if err != nil {
        return nil, err
    }

    worker := &CloudRunWorker{
        id:      uuid.New().String(),
        outpost: o.name,
        issue:   issue,
        events:  events,
        status:  WorkerStatusWorking,
    }

    o.mu.Lock()
    o.workers[worker.id] = worker
    o.mu.Unlock()

    go worker.monitor()
    return worker, nil
}
```

## CloudRunWorker

```go
type CloudRunWorker struct {
    id      string
    outpost string
    issue   string
    status  WorkerStatus
    events  <-chan WorkEvent
    logs    []string
}

func (w *CloudRunWorker) Attach() error {
    return errors.New("Cloud Run workers do not support attach")
}

func (w *CloudRunWorker) Logs() (io.Reader, error) {
    return strings.NewReader(strings.Join(w.logs, "\n")), nil
}
```

Recreate beads rigs with fresh clones

## Problem

Beads rigs have schema mismatches (missing thread_id column, etc.) from development iteration.

## Tasks

1. Shut down any active polecats
2. Delete existing beads rigs: mayor/rig, refinery/rig, witness/rig, crew/*
3. Re-clone from beads repo
4. Run bd init in each new clone

## Rigs to recreate

- /Users/stevey/gt/beads/mayor/rig
- /Users/stevey/gt/beads/refinery/rig
- /Users/stevey/gt/beads/crew/* (if any)

## Source

Clone from beads repo (need to confirm remote URL)


Polecats should not bd sync on startup

Polecats all share the same beads database at the rig level. The refinery and mayor/witness manage syncing beads.

## Current Behavior
Polecat startup runs bd sync, causing:
- Contention when multiple polecats spawn simultaneously
- Unnecessary sync operations
- Potential race conditions

## Desired Behavior
- Polecats should NOT run bd sync on startup
- They read from the shared beads database
- Only refinery/witness/mayor sync beads

## Implementation
Remove bd sync from polecat spawn/startup sequence.


Swarm learning: Spawn should auto-notify polecats

town spawn assigns issues but doesn't notify polecats. Required separate 'town session send' to inject prompts. This should be one atomic operation - spawn assigns AND pokes the polecat to start working.


Add crew session pattern to lifecycle handling

Update identityToSession and restartSession to handle crew patterns: gastown/max -> gt-gastown-max. Crew workers can request lifecycle but are not proactively monitored.


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.


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
```


Spawn inject: Enter not submitted after multiline paste

When gt spawn injects a multiline context (85+ lines), Claude Code shows
'[Pasted text #1 +85 lines]' but the prompt is not submitted.

The tmux SendKeys function does include 'Enter' but it appears to not work
for long pasted text:

```go
func (t *Tmux) SendKeys(session, keys string) error {
    _, err := t.run("send-keys", "-t", session, keys, "Enter")
    return err
}
```

Possible fixes:
1. Use tmux paste-buffer instead of send-keys for long text
2. Send Enter separately after the text
3. Use bracketed paste mode correctly

Reproduction:
```bash
gt spawn gastown/Nux --issue gt-u1j.13 --create
# Session shows pasted text but waits at prompt
```


gt orphans: Find lost polecat work

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

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

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

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

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


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)

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


Swarm package: Swarm, SwarmTask, SwarmState types

Define core swarm types.

## Types (in `internal/swarm/`)

```go
// SwarmState represents swarm lifecycle
type SwarmState string
const (
    SwarmCreated   SwarmState = "created"
    SwarmActive    SwarmState = "active"
    SwarmMerging   SwarmState = "merging"
    SwarmLanded    SwarmState = "landed"
    SwarmFailed    SwarmState = "failed"
    SwarmCancelled SwarmState = "cancelled"
)

// Swarm references a beads epic that tracks swarm work
type Swarm struct {
    ID          string      // matches beads epic ID
    RigName     string
    EpicID      string      // beads epic tracking this swarm
    BaseCommit  string      // git SHA all workers branch from
    Integration string      // integration branch name
    State       SwarmState
    CreatedAt   time.Time
    Workers     []string    // polecat names assigned
}

// SwarmTask represents a single task in the swarm (maps to beads issue)
type SwarmTask struct {
    IssueID   string  // beads issue ID
    Assignee  string  // polecat name
    Branch    string  // worker branch name
    State     string  // mirrors beads status
}
```

## Note

Swarm state is primarily stored IN beads. These types are in-memory representations for the SwarmManager to work with. No separate manifest.json files.

CLI: worker status reporting commands

Worker status reporting CLI for polecats to report progress.

## Commands

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

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

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

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

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

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

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

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

## New File
internal/cmd/worker.go

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

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


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


CLI: mail commands (send, inbox, read)

CLI: mail commands wrapping bd mail.

## Status

Current implementation works with JSONL files. Refactor to wrap bd mail CLI.

## Commands

### gt mail inbox
```
gt mail inbox [--unread] [--json]
```
Wraps: `bd mail inbox [--json]`

### gt mail read
```
gt mail read <id>
```
Wraps: `bd mail read <id> && bd mail ack <id>`
Note: bd mail read + ack marks as read.

### gt mail send
```
gt mail send <address> -s "Subject" -m "Body" [--notify]
```
Wraps: `bd mail send <recipient> -s "Subject" -m "Body"`
If --notify: inject tmux notification after send.

### gt mail delete
```
gt mail delete <id>
```
Wraps: `bd mail ack <id>` (closes the message issue)

## Address Translation

Same as gt-u1j.6:
- `mayor/` → `mayor`
- `<rig>/refinery` → `<rig>-refinery`
- `<rig>/<polecat>` → `<rig>-<polecat>`

## Dependencies

- gt-u1j.6: Mail system backend


Add molecules.jsonl as separate catalog file for template molecules


gt session restart/status: Complete session management

Add missing session subcommands:

- gt session restart <rig> <polecat> - Restart a session (stop + start)
- gt session status <rig> <polecat> - Show session status details

status should show:
- Running state
- Uptime
- Current activity
- Last output timestamp


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


Swarm: report generation

Generate markdown reports for completed swarms.

## Command
```
gt swarm report <swarm-id> [--save <file>]
```

## Report Content

### Header
- Swarm ID and title
- Created/completed timestamps
- Duration
- Rig name

### Task Summary
| Task | Assignee | Status | Duration |
|------|----------|--------|----------|
| gt-xxx | Toast | merged | 15m |
| gt-yyy | Nux | merged | 22m |

### Worker Contributions
- Commits per worker
- Issues closed per worker
- Lines changed (optional)

### Timeline
- Chronological events from events.jsonl
- Key milestones (started, first merge, landing)

### Issues Encountered
- Conflicts resolved
- Failed tasks (if any)
- Escalations

## Implementation
```go
func GenerateReport(swarmID string) (*SwarmReport, error)
func (r *SwarmReport) ToMarkdown() string
```

## Storage
- Save to <rig>/.gastown/swarms/<id>/report.md
- Or user-specified path with --save

## PGT Reference
gastown-py/src/gastown/swarm/manager.py generate_report()

## Acceptance Criteria
- [ ] Markdown report generated
- [ ] Includes all sections above
- [ ] Auto-saved to swarm directory
- [ ] --save allows custom path


Success handling: close MR, close source issue, cleanup

Handle successful merge completion.

Steps:
1. Update MR with merge_commit SHA:
   bd update <id> --body='...\nmerge_commit: <sha>'
2. Close MR with reason:
   bd close <id> --reason='merged'
3. Close source issue (the work item):
   bd close <source_issue> --reason='Merged in <mr_id>'
4. Delete source branch (if configured):
   git push origin --delete <mr.branch>
5. Log success

Configuration:
- delete_merged_branches: bool (default true)

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


Per-rig beads repo configuration

Add per-rig beads configuration to rig config schema.

## Config Schema

In each rig's config.json:

```json
{
  "version": 1,
  "name": "wyvern",
  "git_url": "https://github.com/steveyegge/wyvern",
  "beads": {
    "repo": "local",    // "local" | "<path>" | "<git-url>"
    "root": null,       // Override bd --root (optional)
    "prefix": "wyv"     // Issue prefix for this rig
  }
}
```

## Repo Options

| Value | Meaning | Use Case |
|-------|---------|----------|
| `"local"` | Use project's `.beads/` | Own projects, full commit access |
| `"<path>"` | Use beads at path | OSS contributions |
| `"<git-url>"` | Clone and use repo | Team shared beads |

## Environment Injection

When spawning polecats, Gas Town sets:
```bash
export BEADS_ROOT="<resolved-path>"
```

## Resolution Logic

```go
func ResolveBeadsRoot(rigConfig *RigConfig, rigPath string) (string, error) {
    beads := rigConfig.Beads
    switch {
    case beads.Root != "":
        return beads.Root, nil
    case beads.Repo == "local" || beads.Repo == "":
        return filepath.Join(rigPath, ".beads"), nil
    case strings.HasPrefix(beads.Repo, "/"):
        return beads.Repo, nil
    case strings.Contains(beads.Repo, "://"):
        return cloneAndResolve(beads.Repo)
    default:
        return filepath.Join(rigPath, beads.Repo), nil
    }
}
```

## Backwards Compatibility

If `beads` section missing, assume `"repo": "local"`.


gt polecat add: should handle existing branch gracefully

## Problem

`gt polecat add gastown Nux` fails if the branch `polecat/Nux` already exists.

## Current Behavior

```
fatal: a branch named 'polecat/Nux' already exists
```

## Expected Behavior

Should either:
1. Reuse the existing branch
2. Or prompt to delete/recreate
3. Or auto-suffix: polecat/Nux-2

## Context

Branch may exist from previous polecat that was removed but branch wasn't cleaned up.


request-shutdown

Send shutdown request to Witness.
Wait for termination.

The polecat is now ready to be cleaned up.
Do not exit directly - wait for Witness to kill the session.

Depends: generate-summary


Keepalive signal from bd/gt commands

Every bd and gt command should touch a keepalive file to signal 'agent is alive/working'.

## Implementation

Touch `<workspace>/.gastown/keepalive.json`:
```json
{"last_command": "bd show gt-99m", "timestamp": "2025-12-18T13:45:00Z"}
```

## Usage by Daemon

- Fresh (< 2 min) → agent is working, skip heartbeat
- Stale (2-5 min) → might be thinking, gentle poke
- Very stale (> 5 min) → likely idle, safe to interrupt

## Benefits

- Zero cost (just file I/O)
- Works during long tool calls
- Doesn't require agent cooperation
- Foundation for smarter backoff strategies


Test message

Test body


Implement handoffs using pinned beads

Replace the current mail-based handoff system with pinned beads.

## Current Problem

Handoff messages get closed before the successor can read them because:
1. `gt mail read` auto-acks (closes) messages
2. `bd mail inbox` only shows open messages
3. Successor sees empty inbox

## Solution

Use pinned beads for handoffs:
- One pinned bead per role: `mayor-handoff`, `<rig>-refinery-handoff`, etc.
- Predecessor updates the content before cycling
- Successor reads on startup via `gt prime`
- Never closes - always available

## Implementation

### 1. Create handoff beads on first cycle
- `bd create --title='Mayor Handoff' --type=task --status=pinned --assignee=mayor`
- Store ID in role config or use well-known naming convention

### 2. Update gt handoff command
- Instead of `bd mail send`, update the pinned handoff bead
- `bd update <handoff-id> --description='...handoff content...'`

### 3. Update gt prime
- Read the role's handoff bead
- Display content to successor

### 4. Compression/reset
- `gt rig reset` clears handoff content
- Or manual: `bd update <handoff-id> --description=''`

## Dependencies

Requires beads-6v2 (StatusPinned) to be implemented first.


Add human escalation configuration

Add overseer contact config to mayor/town.json. Deacon uses this for escalation when it cannot resolve issues. Support email and/or other notification methods.


Create DEACON.md role context

Create ~/gt/DEACON.md with the Deacon's role context, wake cycle instructions, and command reference. Model after existing CLAUDE.md for Mayor.


Auto-handoff: self-cycling with guaranteed work pickup

## Summary

A mechanism for agents to self-cycle: send handoff mail, request Deacon to kill the process, and automatically restart to pick up the work.

## Use Case

User says: `auto-handoff: gt-bug3`

The agent:
1. Sends handoff mail documenting current state
2. Requests Deacon to terminate the session
3. Deacon restarts the agent in background
4. New session picks up the handoff and continues working

When the user returns to terminal, the old session is gone but work continues in background. User can reattach.

## Key Requirements

- **Guaranteed pickup**: Something in the hook and/or handoff must ensure the new session picks up the work (not just a passive "check inbox")
- **Background execution**: Work continues without user presence
- **Reattachability**: User can reconnect to see progress

## Design Questions

1. Can molecules help coordinate this? (e.g., molecule binds the handoff + auto-restart)
2. What hook handles the pickup guarantee?
3. How does Deacon know to restart vs just kill?
4. How does user reattach to a background agent?

## Related

- Deacon lifecycle management
- Handoff hooks


Polecat prompting: gt mq submit on completion

Update Polecat CLAUDE.md prompting to:

1. On task completion, run: gt mq submit --issue <id>
2. This creates a merge-request bead in the queue
3. Engineer will process it

The Polecat self-reports completion to the merge queue.


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.


Document how to configure a Gas Town Harness

Create docs explaining what a harness is (private repo containing GT installation with rigs gitignored), why you'd want one, and how to set it up with beads redirects

Beads epic templates for batch work patterns

Optional: Define templates for common batch work patterns.

## Concept

A template encodes a workflow pattern that can be instantiated as beads:

```yaml
# templates/batch-basic.yaml
name: basic-batch
description: Simple batch work pattern
phases:
  - name: startup
    issues:
      - title: "Verify workers ready"
  - name: working
    # Actual work issues added separately
  - name: cleanup
    issues:
      - title: "Merge all branches"
      - title: "Clean up workers"
      - title: "Report to Mayor"
```

## Usage

```bash
gt spawn --template basic-batch --epic gt-u1j --workers 3
```

Creates beads epic with template phases + actual work from gt-u1j children.

## Decision Point

Templates are OPTIONAL. The core design (beads as state, multi-wave orchestration) works without templates. Templates are sugar for common patterns.

Consider deferring to P3 or dropping entirely if beads epics with dependencies suffice.

## Note

No "swarm IDs" involved - templates just pre-populate epic/issue structure.

CloudRunOutpost: Basic implementation

## Overview

Basic CloudRunOutpost implementation. Persistent connections and cost tracking are separate tasks.

## Implementation

```go
type CloudRunOutpost struct {
    name        string
    project     string
    region      string
    service     string
    maxWorkers  int
    client      *WorkClient
    workers     map[string]*CloudRunWorker
    mu          sync.RWMutex
}

func NewCloudRunOutpost(cfg OutpostConfig) (*CloudRunOutpost, error) {
    serviceURL := fmt.Sprintf(
        "https://%s-%s.a.run.app",
        cfg.Service, cfg.Region,
    )
    return &CloudRunOutpost{
        name:       cfg.Name,
        project:    cfg.Project,
        region:     cfg.Region,
        service:    cfg.Service,
        maxWorkers: cfg.MaxWorkers,
        client:     NewWorkClient(serviceURL),
        workers:    make(map[string]*CloudRunWorker),
    }, nil
}
```

## Spawn

```go
func (o *CloudRunOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    req := WorkRequest{
        IssueID: issue,
        Rig:     RigConfig{URL: cfg.RigURL, Branch: cfg.GitBranch},
        Beads:   BeadsConfig{URL: cfg.BeadsURL, Branch: "beads-sync"},
        Branch:  "polecat/" + issue,
    }

    events, err := o.client.DispatchWork(context.Background(), req)
    if err != nil {
        return nil, err
    }

    worker := &CloudRunWorker{
        id:      uuid.New().String(),
        outpost: o.name,
        issue:   issue,
        events:  events,
        status:  WorkerStatusWorking,
    }

    o.mu.Lock()
    o.workers[worker.id] = worker
    o.mu.Unlock()

    go worker.monitor()
    return worker, nil
}
```

## CloudRunWorker

```go
type CloudRunWorker struct {
    id      string
    outpost string
    issue   string
    status  WorkerStatus
    events  <-chan WorkEvent
    logs    []string
}

func (w *CloudRunWorker) Attach() error {
    return errors.New("Cloud Run workers do not support attach")
}

func (w *CloudRunWorker) Logs() (io.Reader, error) {
    return strings.NewReader(strings.Join(w.logs, "\n")), nil
}
```

## Files

- `internal/outpost/cloudrun.go`

## Dependencies

Depends on: gt-9a2.1 (interfaces), gt-9a2.12 (HTTP client)
Blocks: gt-9a2.13 (persistent connections), gt-9a2.14 (cost tracking)


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.


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.


Witness pre-kill verification protocol

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

## Protocol for Witness Prompting

```markdown
## Pre-Kill Verification Protocol

Before killing any worker session, verify workspace is clean.

### Verification Steps

When a worker signals done:

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

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

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

### Nudge Templates

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

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

### Kill Sequence

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

### Escalation

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

## Implementation

Add to WITNESS_CLAUDE.md template.


Polecats should auto-cleanup after MR submission

Currently polecats must manually run 'gt handoff --shutdown' after completing work. This is error-prone and leaves stale polecats around.

## Desired Flow

1. Polecat completes work
2. Polecat runs 'gt mq submit' (or similar)
3. MR is added to integration queue
4. **Polecat automatically cleans up** (no manual handoff needed)

## Implementation Options

### Option A: mq submit triggers cleanup
In 'gt mq submit':
1. Submit MR to queue
2. Automatically run cleanup (same as gt handoff --shutdown)
3. Polecat session terminates

### Option B: Refinery triggers cleanup
When Refinery picks up MR:
1. Refinery processes MR
2. Sends message to Witness: 'CLEANUP: <polecat>'
3. Witness cleans up polecat

### Option C: Molecule-driven
Define cleanup as final phase of polecat-work molecule:
1. code → test → submit-mr → cleanup

## Note
This reinforces the ephemeral model: polecats exist only for the duration of a single task.


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


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.

Retry logic: exponential backoff for transient failures

Implement retry logic for transient failures.

Retryable failures:
- Push failed (network, auth transient)
- Test flaky (config: retry_flaky_tests)
- Fetch failed (network)

Retry strategy:
- Max retries: 3 (configurable)
- Backoff: 1s, 2s, 4s (exponential)
- On final failure: treat as permanent, assign back

Non-retryable failures:
- Merge conflict
- Test consistently fails
- Build error

Track retry count in MR metadata for debugging.

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

Polecat management CLI commands.

## Commands

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

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

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

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

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

## Address Format

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

## Implementation

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


gt spawn: Not injecting work instructions to session

gt spawn starts session but doesn't inject the issue assignment.

Repro:
1. gt spawn gastown/Toast --issue gt-2ux
2. Session starts but polecat just sees Claude prompt
3. No issue context injected

Expected: Polecat should receive issue details automatically.
Actual: Polecat sits at blank prompt, needs manual injection.


Phase 4.2: Witness/Refinery patrol molecules

Extend ephemeral patrol pattern to Witness and Refinery.

## Witness Patrol Cycle

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

## Refinery Patrol Cycle

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

## Quiescent Mode

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


TIDY UP: Your previous work (gt-odvf: bd mol CLI docs) wa...

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


Phase 4: Polish and observability

Production readiness.

## Commands
- gt patrol status - Show patrol state for all agents
- gt patrol history - Recent patrol activity

## Observability
- Metrics collection
- Alert thresholds
- Dashboard (optional)

## Tuning
- Cooldown optimization
- Wake SLA verification
- Error threshold tuning

Depends: Phase 3

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)


Update lifecycle mail targets to deacon/

Update Mayor, Witness, and Crew handoff code to send lifecycle requests to deacon/ instead of daemon/. Update internal/cmd/handoff.go and related code.


Bubbletea TUI dashboard

Interactive TUI using Charm Bubbletea. Root model, view routing, Lipgloss theme. Includes: dashboard, rig explorer, polecat detail with live tail, mail view, beads view, spawn wizard.


Patrol System: Agent lifecycle loops with attachments

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

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

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

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

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


Merge: gt-h5n.5

branch: polecat/Scabrous
target: main
source_issue: gt-h5n.5
rig: gastown


Deacon event/timer callbacks: reactive triggers

Implement event-triggered and timer-based callbacks in the Deacon.

## Timer Callbacks

Agents can schedule future wakes by mailing the Deacon:
```
Subject: TIMER: gastown/witness wake at 2025-12-20T16:00:00Z
Body: Please nudge me - I'm waiting for external dependency
```

Deacon processing:
1. Parse timer mail
2. Check if time has passed
3. If yes: mail the agent "WAKE: Timer fired"
4. Close the timer mail

## Event Subscriptions

Plugins/agents can subscribe to events:
```yaml
# In kernel bead or plugin config
event_triggers:
  - event: "issue.created"
    action: mail
    target: "plugins/work-oracle"

  - event: "mr.submitted"
    action: run
    plugin: "review-oracle"

  - event: "agent.stuck"
    action: escalate
    target: human
```

## Event Sources

Events come through mail to deacon/:
```
Subject: EVENT: issue.created gt-abc123
Body: New issue created in gastown rig
```

## Event Types

Initial event types:
- `issue.created` - New bead created
- `issue.closed` - Bead closed
- `mr.submitted` - Merge request submitted
- `mr.merged` - Merge request merged
- `agent.stuck` - Agent appears stuck (from health scan)
- `agent.failed` - Agent remediation failed

## Event Processing

During events step:
1. Read event mail from inbox
2. Match against subscriptions
3. Execute actions:
   - `mail`: Send mail to target
   - `run`: Execute plugin inline
   - `spawn`: Spawn subagent for plugin
   - `escalate`: Mail human

## Relation to Mail

Mail IS the event bus. No separate event system.
Events are just specially-formatted mail to deacon/.


Swarm learning: Refinery merge queue automation

Manually merging 15 polecat branches was painful and error-prone. Refinery should automate: detect completed work, run tests, merge to main, handle conflicts. This is core Refinery value prop.


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


Daemon: integration test with real lifecycle

Need an end-to-end test that:
1. Starts daemon
2. Starts a test agent session
3. Sends lifecycle request to daemon
4. Verifies session was killed and restarted
5. Cleans up

Could use a mock 'agent' that's just a shell script.
