bd create --dedup: semantic deduplication before issue creation

Before creating issue, check for semantic duplicates using AI similarity.

**From VC**: internal/deduplication/ - AI-powered batch comparison. ~300 lines.
VC had issue pollution problem: 438 issues with ~350+ spam because no early dedup.

**Gas Town implementation**: CLI flag on bd create:
```bash
bd create --dedup --title="Fix auth bug" --description="..."
```

Checks recent issues (7-day window) with AI similarity. If confidence >0.85, warns or blocks.

**Value**: Prevents pollution from parallel workers discovering same issues.

**VC lesson**: 115 issues filed in single day (Nov 2) because supervisor over-discovered without dedup. Rate limiting + dedup are essential.


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)


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.


Merge: gt-92l

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


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


bd create should support molecule type

gt molecule commands expect type=molecule but bd validates against bug|feature|task|epic|chore|merge-request only


Built-in molecules: engineer-in-box, quick-fix, research

Create built-in molecules as Beads issues:

## engineer-in-box

```markdown
id: mol-engineer-in-box
type: molecule
title: Engineer in a Box

Full workflow from design to merge.

## Storage

Built-in molecules live in `<town>/.beads/` as regular issues.
Created during `gt install` or `bd init`.


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.


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

Consolidate configuration architecture: three-tier model

Rationalize Gas Town's scattered configuration into a clean three-tier model:

## Current Problems
- Config split across mayor/, .gastown/, and rig/config.json
- Runtime state mixed with configuration
- Hidden directories (.gastown/) are missed by agents
- Category confusion: identity vs config vs runtime state

## Proposed Architecture

### Tier 1: Town Config (mayor/)
```
mayor/
├── town.json      # Town identity (unchanged)
├── rigs.json      # Rig registry (unchanged)
└── config.json    # NEW: Town-level configuration
    # theme defaults, daemon settings, etc.
```

### Tier 2: Town Runtime (.runtime/)
```
~/gt/.runtime/                    # NEW: Gitignored
├── daemon.json                   # {pid, started_at, heartbeat}
├── deacon.json                   # {cycle, last_action}
└── agent-requests.json           # Lifecycle requests
```

### Tier 3: Rig Config (settings/)
```
<rig>/
├── config.json                   # Rig identity only (type, git_url, beads.prefix)
├── settings/                     # NEW: Visible, git-tracked
│   ├── config.json               # theme, merge_queue, max_workers
│   ├── namepool.json             # pool settings (style, max)
│   └── roles/                    # Per-role overrides (optional)
└── .runtime/                     # NEW: Gitignored
    ├── witness.json              # {state, started_at, stats}
    ├── refinery.json             # {state, started_at, stats}
    └── namepool-state.json       # {in_use, overflow_next}
```

## Key Principles
1. **Visible > Hidden** for config agents need to find
2. **Git-tracked** for identity and config; **gitignored** for runtime
3. **Separation of concerns**: identity, config, runtime are distinct
4. **Locality**: town config at town root, rig config at rig root

## Migration
- Move .gastown/ contents to appropriate new locations
- Update all code that reads/writes these files
- Update .gitignore patterns
- Update documentation (architecture.md, CLAUDE.md)


Molecules: Composable Workflow Beads

## Summary

Molecules are crystallized workflow patterns stored as Beads issues.
When instantiated, the molecule creates child beads forming a DAG.

## Key Insight: Molecules ARE Beads

Per HOP Decision 001: Beads IS the ledger. Molecules don't get a separate YAML format - they're issues with `type: molecule` containing prose-based step definitions.

Agents don't need rigid schemas. They parse natural language natively. A molecule is just instructions with enough structure for tooling.

## Example: Engineer in a Box

```markdown
id: mol-xyz
type: molecule
title: Engineer in a Box

This workflow takes a task from design to merge.

## Step: design
Think carefully about architecture. Consider existing patterns,
trade-offs, testability.

## Step: implement
Write clean code. Follow codebase conventions.
Needs: design

## Step: review
Review for bugs, edge cases, style issues.
Needs: implement

## Step: test
Write and run tests. Cover happy path and edge cases.
Needs: implement

## Step: submit
Submit for merge via refinery.
Needs: review, test
```

## Instantiation

```bash
# Attach molecule when spawning
gt spawn --issue gt-abc --molecule mol-xyz

# Creates child beads atomically:
gt-abc.design     ← ready first
gt-abc.implement  ← blocked by design
gt-abc.review     ← blocked by implement
gt-abc.test       ← blocked by implement
gt-abc.submit     ← blocked by review, test
```

Each step issue gets an `instantiated-from` edge to the molecule (with step metadata).

## Why This Matters

1. **Unified data plane**: Everything in Beads, no parallel YAML channel
2. **AI-native**: Prose instructions, not rigid schemas
3. **Error isolation**: Each step is a checkpoint - failure doesn't lose progress
4. **Scales with AI**: As agents get smarter, they handle more complex molecules

## Implementation Primitives

- `ParseMoleculeSteps()`: Extract steps from prose (convention-based)
- `InstantiateMolecule()`: Atomic transaction creating all steps + edges
- `instantiated-from` edge type: Track provenance
- Parameterization: `{{variable}}` substitution from context map


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.


implement

Implement the solution for gt-qwyu. 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


Mayor handoff mail template

Add MAYOR_HANDOFF mail template to templates.py.

## Template Function

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

## Metadata Fields

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

## Mail Priority

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


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)

mol-theme-generate: Custom name pool generation via cognition

Currently polecat name themes are hardcoded in namepool.go. Simple theme selection is fine as static config, but custom name generation should be a molecule.

Examples requiring cognition:
- "Generate 50 polecat names in the style of [book/movie/game]"
- "Create names that match the project's domain (medical, financial, etc.)"
- "Extend the mad-max theme with 20 more obscure characters"

## Molecule: theme-generate
Generate custom polecat names for a rig.

## Step: analyze-request
Understand the naming request:
- Theme style or source material
- Number of names needed
- Any constraints (length, format)

## Step: generate-candidates
Generate candidate names matching the style.
Aim for 2x the requested count.

## Step: validate-names
Filter candidates:
- No duplicates with existing themes
- Appropriate length (3-15 chars)
- No problematic terms

## Step: create-theme
Write the custom theme to rig config or beads.
Register in name pool.
Needs: validate-names

## Notes
- Output is a new theme entry in BuiltinThemes equivalent
- Could be stored as a pinned bead for persistence


Complete gt crew commands (list, attach, remove, refresh, status)

Add remaining crew subcommands to internal/cmd/crew.go:

1. gt crew list - List crew workspaces with status
2. gt crew at/attach - Start tmux session in crew workspace
3. gt crew remove - Remove crew workspace (with safety checks)
4. gt crew refresh - Context cycling with mail-to-self handoff
5. gt crew status - Show detailed workspace status

Build on existing crew add implementation in internal/cmd/crew.go.
Reference closed issues gt-cik.3-7 for original requirements.

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.


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

Witness Plugin System

Plugin infrastructure for witness patrol customization.

## Plugin Location
`<rig>/plugins/witness/<plugin-name>/`

## Plugin Structure
```
plugin.yaml   # Config: name, description, trigger, tier
prompt.md     # The prompt to run
```

## plugin.yaml Schema
```yaml
name: plugin-name
description: What it does
trigger: patrol          # When to run (patrol, on-nudge, on-shutdown)
tier: haiku              # Model tier (haiku, sonnet, opus)
input: polecat-list      # What context to gather (polecat-list, session-capture, etc)
```

## Execution
1. Witness reads plugins from directory
2. For each plugin matching current trigger:
   - Gather specified input context
   - Run prompt.md against specified tier
   - Parse output for gt commands
   - Execute commands

## CLI
- `gt plugin list <rig>` - List installed plugins
- `gt plugin run <rig> <plugin>` - Manual run


Deacon: Hierarchical health-check orchestrator

Replace daemon heartbeats with Deacon - an AI agent that keeps Gas Town running.

## Core Concept

The Deacon is a **Claude agent** (not just a Go process) that:
- Lives at town root in gt-deacon session
- Has its own mailbox (deacon/ identity in town beads)
- Is poked by a minimal Go daemon every ~60s (if idle)
- Monitors Mayor and Witnesses proactively
- Handles lifecycle requests (restart/cycle) from Mayor, Witnesses, AND Crew

## Architecture

```
Minimal Go Daemon (just watches Deacon)
         |
         v
     Deacon (Claude agent)
         |
    +----+----+
    v         v
  Mayor    Witnesses --> Polecats (Witness-managed)
    |         |
    +----+----+
         |
      Crew (lifecycle only, not monitored)
```

## Deacon Responsibilities

**Proactive monitoring:**
- Mayor health (tmux session, keepalive freshness)
- Witness health (tmux sessions, keepalive freshness)

**Reactive lifecycle:**
- Process restart/cycle requests from Mayor, Witnesses, Crew
- Kill session, create new, prime, verify startup

**Escalation:**
- Mail human (configurable) if issues can't be resolved

## Key Files

- ~/gt/DEACON.md - Role context
- ~/gt/deacon/ - State directory
  - heartbeat.json - Written each wake cycle (daemon checks this)
  - state.json - Health tracking, last scan results
- ~/gt/.beads/ - Town beads with deacon/ mail identity

## Wake Cycle

1. Write heartbeat (prevents daemon from poking)
2. Check mail (lifecycle requests)
3. Quick health scan (Mayor, Witnesses)
4. Process lifecycle requests
5. Remediate unhealthy agents
6. Update state

## Session Patterns

- Deacon: gt-deacon
- Mayor: gt-mayor
- Witness: gt-<rig>-witness
- Crew: gt-<rig>-<name> (e.g., gt-gastown-max)

## Relation to Policy Beads

Future: Deacon behavior configurable via policy beads (gt-3zw).
Initial implementation uses sensible defaults.


CLI: doctor diagnostics and auto-repair

GGT completely lacks the doctor command which is critical for debugging.

Required Commands:
- gt doctor [<rig>] - Run diagnostic checks
- gt doctor --fix - Auto-repair common issues

Checks to Implement:
Workspace Level: Config validity, Mayor mailbox, Rig registry
Rig Level: Git state, clone health, witness/refinery presence, beads sync
Swarm Level: Stuck detection, zombie sessions, heartbeat health

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


Witness patrol: cleanup idle orphan polecats

Add patrol step to find and cleanup polecats that are idle with no assigned issue. These orphans occur when polecats crash before sending DONE or Witness misses the message. Patrol should verify git is clean before removing worktree. Part of gt-rana.

gt rig reset: clear stale mail on reset/land

## Problem

When resetting or landing a rig/town, stale mail messages can confuse agents on startup. Old handoff messages, daemon notifications, and inter-agent mail should be cleaned up as part of reset.

## Current State

- `gt rig reset` exists but doesn't clear mail
- Stale messages accumulate (e.g., daemon SHUTDOWN messages)
- Agents may read outdated context on startup

## Proposed Behavior

`gt rig reset` and `gt town reset` should:
1. Close all open messages (`--type=message`) in the relevant beads
2. Optionally preserve pinned handoff beads (clear content, keep bead)
3. Log what was cleaned up

```bash
gt rig reset gastown          # Clears gastown mail
gt rig reset gastown --mail   # Only clear mail, keep other state
gt town reset                 # Clears all town-level mail
gt town reset --all           # Clears mail in all rigs too
```

## Implementation

1. Query `bd list --type=message --status=open`
2. Close each with reason 'Cleared during reset'
3. For pinned handoffs: `bd update <id> --description=''` instead of close


CloudRun cost tracking: Usage monitoring and limits

## Overview

Track Cloud Run usage costs and enforce spending limits.

## Cost Model

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

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

## Implementation

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

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

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

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

## Cost Cap Enforcement

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

## Config

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

## CLI

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

## Files

Implement shared beads architecture for rig

Implement redirect-based shared beads to eliminate git sync overhead within a rig.

## Background
Each polecat currently has its own .beads/ directory synced via git. This burns tokens on sync operations.

## Solution
Use bd's redirect feature:
1. Create single shared .beads/ at rig root
2. Polecats get redirect files pointing to shared location
3. All agents connect to same daemon
4. SQLite WAL + daemon serialization handles concurrency

## Implementation
1. Create shared .beads/ at rig root (e.g., ~/gt/gastown/.beads/)
2. Update gt spawn to create redirect files:
   mkdir -p polecats/nux/.beads
   echo ../../.beads > polecats/nux/.beads/redirect
3. Test that all polecats connect to same daemon
4. Remove git sync from intra-rig workflow
5. Keep JSONL export for backup/cross-rig only

## Reference
beads/polecats/rictus/internal/beads/beads.go:45 - followRedirect()


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.

Refinery background daemon mode

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

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

## Requirements

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

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

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

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

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

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

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

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

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

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

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

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


Swarms of One: Lightweight single-worker task dispatch

Design and implement a lightweight pattern for firing off single workers to handle tasks without full swarm overhead.

## Context

Currently we have:
- town spawn: Creates a polecat in a rig with issue assignment
- Swarms (sw-*): Full lifecycle tracking with manifest, state, events, reports
- Ephemeral rigs (rig-*): Temporary worker groups for swarms

What's missing: A simple way to say 'fire off a worker to do X' without swarm ceremony.

## Design Questions

1. Should this be a new command like 'gt fire' or an option on existing commands?
2. Should single tasks still get swarm IDs (sw-N) for consistency/queryability?
3. Should it default to creating new workers or support --reuse for idle polecats?
4. How does this relate to crew workers (gt-cik)?

## Possible Interface

gt fire --rig gastown --issue gt-xyz [--prompt '...']
gt fire gastown/QuickTask --issue gt-xyz

## Related

- gt-kmn: Swarm System epic


Plugin: plan-oracle (work decomposition)

Plugin that helps decompose epics/issues into sub-tasks. Analyzes scope, identifies dependencies, estimates complexity for parallelization, creates beads for sub-tasks with dependency links.


Polecats should not push branches to remote

## Current Behavior

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

## Desired Behavior

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

## Benefits

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

## Trade-offs

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

## Implementation

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


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.

Add gt deacon start/stop/status commands

Add CLI commands: gt deacon start (spawn gt-deacon session), gt deacon stop (kill session), gt deacon status (show health state). Similar to gt mayor commands.


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.

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.


Update vision.md with proto/mol/wisp terminology

Update the Steam Engine Metaphor section to use consistent phase terminology:

Current (vision.md):
- Proto molecules = fuel (templates)
- Wisps = steam (transient execution traces)
- Digests = distillate (permanent records)

New terminology:
- **Proto** = crystal/solid - frozen template
- **Mol** = liquid - reified durable instance (tracked in git)
- **Wisp** = gas - ephemeral instance (evaporates after squash)
- **Digest** = distillate - compressed summary after squash

Key clarification needed:
- Proto → bond → creates either Mol (durable) or Wisp (ephemeral)
- The choice of Mol vs Wisp depends on --wisp flag
- Default is Mol (durable, recorded in main beads)
- Wisp lives in .beads-ephemeral/, squashes away


MR field parsing: extract structured fields from description

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

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

Document bd mol bond/squash/burn CLI

Create CLI reference documentation for molecule commands:

## bd mol bond

Instantiate a proto into a runnable molecule.

```bash
bd mol bond <proto-id> [--wisp] [--assignee=<addr>]
```

- Default: creates a Mol (durable, in main beads)
- --wisp: creates a Wisp (ephemeral, in .beads-ephemeral/)
- --assignee: who will execute this molecule

## bd mol squash

Complete a molecule and generate digest.

```bash
bd mol squash <mol-id> --summary='...'
```

- For Mol: creates digest in git history
- For Wisp: evaporates (no permanent record)
- --summary: required summary of what was accomplished

## bd mol burn

Abandon a molecule without completing.

```bash
bd mol burn <mol-id> [--reason='...']
```

- Discards molecule state
- No digest created
- Use when molecule is no longer needed


orphan-check

Find abandoned work. Check for in_progress issues with no active agent.


Digest: mol-deacon-patrol

Test patrol cycle - first run, no actual work done


Molecule composition: Includes directive

Add support for molecule composition via the Includes directive.

## Format
\`\`\`markdown
## Molecule: derived-name
Includes: mol-base-molecule

## Step: additional-step
Additional instructions here.
Needs: step-from-base
\`\`\`

## Implementation
1. Add \`Includes:\` parsing to ParseMoleculeSteps()
2. Resolve included molecule by ID
3. Merge steps from included molecule
4. Allow new steps to depend on included steps
5. Support multiple includes (polymers)

## Files to modify
- internal/beads/molecule.go
- internal/beads/molecule_test.go

## Acceptance
- [ ] Parse Includes directive
- [ ] Resolve and merge included steps
- [ ] Dependencies across molecules work
- [ ] Multiple includes supported
- [ ] Tests cover composition scenarios


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)


Activity feed from wisp state: gt patrol status

Enable mayor and gt tool to quickly see what patrol agents are doing.

## Problem

The mayor and gt tool cannot quickly see what the deacon (or other patrol agents) are doing.
Need a way to extract an activity feed from the current wisp state.

## Desired Commands

- gt patrol status: Show current patrol state (step, timing, cycle count)
- gt patrol history: Show recent patrol cycles (from digests)
- gt patrol feed: Live tail of patrol activity

## Data Sources

- .beads-wisp/issues.jsonl: Current wisp with step progress
- .beads/issues.jsonl: Digests from squashed patrols
- heartbeat.json: Last activity timestamp

## Use Cases

1. Mayor checking deacon: Is the deacon doing anything?
2. Debugging hangs: What step is it stuck on?
3. Operator monitoring: Dashboard of patrol health
4. Summaries for handoffs: Auto-generate patrol digest

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.


Witness updates: Remove issue filing proxy

Update Witness prompting to remove issue filing proxy, since polecats now have direct beads access.

## Remove from Witness Prompting

The following is NO LONGER Witness responsibility:
- Processing polecat 'file issue' mail requests
- Creating issues on behalf of polecats
- Forwarding issue creation requests

## Add: Legacy Request Handling

If Witness receives an old-style 'please file issue' request:

1. Respond with update:
   town inject <polecat> "UPDATE: You have direct beads access now. Use bd create to file issues yourself."

2. Do not file the issue - let the polecat learn the new workflow.

## Keep in Witness Prompting

- Monitoring polecat progress
- Nudge protocol
- Pre-kill verification
- Session lifecycle management

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
```

Add unit tests for daemon package

The daemon package has no unit tests. Need tests for:
- Config and state serialization
- Session name pattern matching (isWitnessSession)
- Lifecycle request parsing
- Identity to session mapping


Default crew name should be something better than 'main'

When creating a new rig, the default crew worker name is 'main'. This is confusing since:

1. 'main' is also the git branch name
2. It doesn't convey that this is the user's personal workspace
3. Crew names should feel more personal/distinct

Consider alternatives like:
- 'home' - the user's home base
- 'desk' - their personal desk
- 'joe/max/etc' - actual name-based defaults
- Let user pick during rig init


CLI: rig commands (list, show, add)

Rig management CLI commands.

## Commands

### gt rig list
List all registered rigs.
```
gt rig list [--json]
```
Output:
- Rig name
- Git URL
- Polecat count
- Witness/Refinery status

### gt rig show
Show details for a specific rig.
```
gt rig show <name> [--json]
```
Output:
- Full rig info
- Polecats with status
- Recent activity
- Beads summary (open issues)

### gt rig add
Add a new rig to the town.
```
gt rig add <name> <git-url>
gt rig add <name> --local <path>
```
Steps:
- Clone repo to town root (or link local)
- Register in rigs.json
- Create agent directories
- Configure git exclude

### gt rig remove
Remove a rig from the town.
```
gt rig remove <name> [--force]
```
- Warns if active polecats
- --force required if uncommitted changes

## Implementation

```go
var rigCmd = &cobra.Command{Use: "rig"}
rigCmd.AddCommand(rigListCmd, rigShowCmd, rigAddCmd, rigRemoveCmd)
```


Patrols: Cyclic molecules for autonomous maintenance

## Vision

Patrols are **cyclic molecules** - workflow loops that give Gas Town its autonomous nervous system. While regular molecules are DAGs that terminate, patrols loop forever, performing maintenance tasks at varying cadences.

This is the "steam engine" of Gas Town: converting episodic Claude sessions into continuous autonomous operation.

## Core Concepts

### 1. Cyclic Molecules

Regular molecule:     A -> B -> C -> done
Patrol molecule:      A -> B -> C --+
                      ^             |
                      +-------------+

Patrols have a loop_to field specifying where to restart.

### 2. Cooldown-Aware Steps (Atoms)

Steps encode their own cadence. When patrol reaches a step:
1. Check: now - last_run > cooldown?
2. If yes: execute, update last_run
3. If no: skip (immediately close)

The patrol runner is simple - steps self-skip. Complexity distributed into atoms.

### 3. The Beacon

The heartbeat that fires patrol triggers:
- Internal ticker in Deacon (goroutine)
- Or external cron firing gt deacon tick
- Or mail-based triggers

Without beacon, nothing proactive happens.

### 4. Session Reset as Patrol Step

Connects to auto-handoff (gt-bcwn). Session reset is a patrol step, not a separate mechanism.

### 5. Multi-Role Patrols

Each supervisor has its own patrol:

**Deacon patrol:** health-check (30s), session-gc (5m), beacon-tick (10s)
**Witness patrol:** orphan-scan (10m), stuck-check (2m), molecule-progress (1m)
**Refinery patrol:** queue-check (30s), pr-status (1m), merge-ready (30s)

### 6. Cadence Tiers

- Critical (10-30s): Health checks
- Active (1-5m): Progress, nudges
- Maintenance (10-30m): Orphans, GC
- Periodic (1h+): Reports

### 7. Best-Effort Scheduling

Not real-time - more like cron. No hard deadlines. Catch-up, dont pile-up.
Priority preemption (mail interrupts patrol). Graceful degradation under load.

## Open Questions

1. State persistence: Beads (self-describing) or file (faster)?
2. Interruption: How does urgent mail preempt patrol?
3. Error recovery: Backoff? Escalate? Circuit breaker?
4. Coordination: Can patrols send mail to trigger other patrols?

## Related

- gt-bcwn: Auto-handoff (session reset is a patrol step)
- Molecule system (patrols extend molecules with loops)
- Deacon lifecycle management

## Metaphor

Claude was fire. Claude Code was steam. Gas Town is the steam engine. Beads is the train tracks.

The steam engine converts episodic combustion into continuous rotary motion.
Gas Town converts episodic Claude sessions into continuous autonomous work.


Doctor check: Worker health and stuck detection

Detect and report stuck workers via gt doctor.

## Checks

### WorkerHealthCheck
- List all active workers (polecats with state=working)
- Check last activity timestamp for each
- Flag as potentially stuck if no progress for configurable threshold (default: 30 min)
- Check if Witness is running for the rig
- Verify Witness last heartbeat time

### Stuck Detection Criteria
- Polecat state=working but session not running
- Polecat state=working but output unchanged for threshold
- Witness not responding to health checks
- Multiple polecats in same rig all stuck

## Output

```
[WARN] Workers in rig 'wyvern' may be stuck:
  - Toast: working for 45m, no recent output
  - Capable: working for 52m, session not found
  - Witness: last heartbeat 20m ago

  Suggestions:
  - gt witness status wyvern
  - gt capture wyvern/Toast 50
  - gt stop --rig wyvern (kill all)
```

## Auto-Fix

Cannot auto-fix stuck workers (risk of data loss), but can:
- Restart Witness daemon if crashed
- Send warning mail to Mayor


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

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.


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)


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.

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.


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


Ephemeral rig support for ad-hoc batch work

Support for temporary worker rigs for ad-hoc batch work.

## Use Case

Ad-hoc batch work where you want temporary workers:
- gt spawn --epic <epic-id> --ephemeral --workers 3
- Creates temp rig with 3 clones
- Workers process epic children
- Work merges through queue
- Clones cleaned up when done

## Interface

```go
type EphemeralRig struct {
    ID               string
    GitURL           string
    BaseCommit       string
    Workers          []string
    IntegrationBranch string
    EpicID           string  // associated epic (for cleanup trigger)
    CreatedAt        time.Time
}

func InitEphemeralRig(gitURL string, numWorkers int) (*EphemeralRig, error)
func (r *EphemeralRig) AddWorker(name string) error
func (r *EphemeralRig) Destroy(force bool) error
```

## Directory Structure

```
<rig>/ephemeral/
└── rig-a3f7/
    ├── config.json
    ├── Alice/     # clone
    ├── Bob/       # clone
    └── Carol/     # clone
```

## Cleanup Trigger

When all issues in the associated epic are closed AND merged, the ephemeral rig can be destroyed.

## Note

No swarm ID needed - the epic ID provides the grouping. Ephemeral rig is just a convenience for temporary clones.

## Reference

PGT: ephemeral.py (for structure, ignore swarm ID coupling)


Add crew lifecycle support to Deacon

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

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

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

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

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

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


Git wrapper: shell out to git

Wrapper for git operations via subprocess.

## Interface

```go
type Git struct {
    workDir string
}

func NewGit(workDir string) *Git

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

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

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

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

## Implementation

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

## Error Handling

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

## Testing

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


gt mail read: Support numeric indices for message ID

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

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

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


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/.

Work on ga-lue: Implement Witness as Claude agent. Convert from shell script to Claude agent that monitors polecats, nudges idle ones, handles escalations. When done, submit MR (not PR) to integration branch for Refinery.


Outpost CLI commands: gt outpost list/status/add

## Overview

CLI commands for managing outposts.

## Commands

```bash
# List configured outposts
gt outpost list
NAME            TYPE       WORKERS   STATUS
local           local      2/4       healthy
gce-burst       ssh        0/8       healthy
cloudrun-burst  cloudrun   0/20      healthy

# Detailed status
gt outpost status [name]
Outpost: cloudrun-burst
Type: cloudrun
Project: my-gcp-project
Region: us-central1
Service: gastown-worker
Active Workers: 3/20
Cost (today): $0.42
Status: healthy

# Add new outpost interactively

Test Epic: GGT MVP Validation


Add bulk session stop command (gt session stop --all)

When decommissioning a rig, need to stop multiple sessions one at a time. A --all or --rig flag would allow: gt session stop --rig gastown


gt nudge should accept flexible session identifiers

Currently `gt nudge` requires the exact tmux session name (e.g., `gt-gastown-furiosa`).

It should also accept:
- `gastown/furiosa` (rig/polecat format)
- `furiosa` (polecat name, infer rig from cwd or require if ambiguous)

The session list command shows `gastown/furiosa` format, but nudge rejects it:
```
gt session list → shows 'gastown/furiosa'
gt nudge gastown/furiosa 'msg' → 'session not found'
gt nudge gt-gastown-furiosa 'msg' → works
```

Should normalize all these formats to the tmux session name internally.


Doctor check: Zombie session cleanup

Detect and clean up zombie tmux sessions via gt doctor.

## Problem

Zombie sessions occur when:
- Agent crashes without cleanup
- gt kill fails mid-operation
- System restart leaves orphan sessions
- Session naming collision

## Checks

### ZombieSessionCheck
- List all tmux sessions matching gt-* pattern
- Cross-reference with known polecats
- Flag sessions with no corresponding polecat state
- Flag sessions for removed polecats
- Check session age vs polecat creation time

### Detection Criteria
- Session exists but polecat directory doesn't
- Session name doesn't match any registered polecat
- Polecat state=idle but session running
- Multiple sessions for same polecat

## Output

```
[WARN] Zombie tmux sessions detected:
  - gt-wyvern-OldPolecat (polecat removed)
  - gt-beads-Unknown (no matching polecat)
  - gt-wyvern-Toast (duplicate session)

  Run 'gt doctor --fix' to clean up
```

## Auto-Fix (--fix flag)

- Kill orphan tmux sessions
- Update polecat state to match reality
- Log all cleanup actions

## Safety

- Never kill sessions where polecat state=working
- Prompt before killing if --fix used without --force
- Create audit log of killed sessions


Direct landing integration: gt land uses MR or bypasses

Integrate direct landing with merge queue.

'gt land --direct' should:
1. Check if MR exists for the polecat's work
2. If MR exists: process it directly (skip queue)
3. If no MR: create temporary MR, process, close

Options:
- --direct: bypass queue (existing)
- --via-queue: ensure goes through queue (new)
- --force: skip safety checks (existing)

This ensures direct landing still creates proper records.

Reference: docs/merge-queue-design.md#direct-landing-bypass-queue


Session cycling UX: smooth transitions via TUI wrapper

## Problem

Current CLI agent session cycling is painful:
- Shell → CC starts → priming → context loads → ready → work → exit/crash → repeat
- Each cycle is 30-60 seconds of cold boot
- No continuity between shell and agent's inner state
- Raw "session not running, starting..." loop is the baseline

## GGT Advantages (already have)

- Beads: Work state survives session death completely
- Mail: Handoff notes from past-self to future-self
- Prime commands: Structured context reload

## Gap: Transition Mechanics

Ideas to explore when actively using CLI:

1. **In-band cycling** - `/restart` or `/cycle` command, agent handles own restart without dropping to shell

2. **Hot standby** - TUI maintains pre-warmed session in background, switch to already-primed agent

3. **Persistent wrapper** - Bubbletea TUI stays running across session cycles, CC sessions come/go inside it

4. **Session pooling** - Keep 2-3 primed sessions ready, never wait for cold start

## Deferred

Deliberately P4 until we're actively using the simpler CLI and feel the pain firsthand.


Implement gt mol status command

Show what's on an agent's hook.

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

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

If no target, shows current agent's status.

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


Use cmd.OutOrStdout instead of fmt.Print in refinery

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

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


Phase 3: Callbacks and plugins

Mail-based callback protocol and plugin surface.

## Callbacks
- Polecat → Witness: shutdown requests
- Witness → Deacon: escalations, status
- Crew → Deacon: recycle requests
- Deacon → Mayor: escalations

## Plugins
- .beads/plugins.yaml registry
- Cooldown tracking
- Plugin runner in deacon patrol

Depends: Phase 2


SwarmManager: create, start, update, query operations

SwarmManager operations for creating and managing swarms.

## Interface

```go
type SwarmManager struct {
    rig    *Rig
    beads  *BeadsWrapper  // shells out to bd CLI
}

func NewSwarmManager(rig *Rig) *SwarmManager

// Lifecycle
func (m *SwarmManager) Create(epicID string, workers []string) (*Swarm, error)
func (m *SwarmManager) Start(swarmID string) error
func (m *SwarmManager) UpdateState(swarmID string, state SwarmState) error
func (m *SwarmManager) Cancel(swarmID string, reason string) error

// Queries (delegate to beads)
func (m *SwarmManager) GetSwarm(id string) (*Swarm, error)
func (m *SwarmManager) GetReadyTasks(swarmID string) ([]SwarmTask, error)
func (m *SwarmManager) GetActiveTasks(swarmID string) ([]SwarmTask, error)
func (m *SwarmManager) IsComplete(swarmID string) (bool, error)
```

## Implementation Notes

- `GetReadyTasks` wraps `bd ready --parent <epicID>`
- `IsComplete` checks if all child issues are closed
- State transitions update the epic's description or a tag field
- No separate manifest files - beads IS the source of truth


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.


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.


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

loop-or-exit

Decision: burn and loop if context low, exit for respawn if context high.


Deacon keepalive: quiet daemon during rounds

Replace tmux-poke interrupts with a keepalive file the daemon respects.

## Problem

Current daemon pokes Deacon via tmux SendKeys every ~5 minutes if heartbeat
is stale. This can INTERRUPT the Deacon mid-work, especially during long
plugin execution or health remediation.

## Solution

Deacon writes a keepalive file at start of rounds:
```json
{
  "timestamp": "2025-12-20T15:30:00Z",
  "expected_duration_minutes": 10,
  "action": "executing mol-deacon-rounds"
}
```

Daemon reads this and backs off:
- If keepalive is fresh AND within expected_duration: skip poke
- If keepalive is stale OR past expected_duration: poke (fallback)

## Files

- `{townRoot}/deacon/keepalive.json` - Written by Deacon
- Daemon already reads `{townRoot}/deacon/heartbeat.json` - similar pattern

## Deacon Behavior

1. Start of rounds: write keepalive with expected duration
2. End of rounds: write heartbeat (existing), clear/update keepalive
3. If rounds take longer than expected: Deacon gets one poke, squelches it

## Daemon Changes

Modify `pokeDeacon()` in daemon.go:
1. Check keepalive.json freshness and expected_duration
2. If within bounds: skip poke, log "Deacon active"
3. If past bounds: poke as fallback

## Worst Case

Deacon crashes mid-rounds without clearing keepalive:
- Daemon waits until expected_duration expires
- Then pokes, triggering respawn loop
- Max delay: expected_duration (configurable, default 10-15 min)

## Configuration

In pinned kernel bead:
```yaml
config:
  rounds_expected_duration_minutes: 10
```


P0: Multiple agents can claim same worker identity

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

## Fix Implemented

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

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

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

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


gt handoff deadlock at handoff.go:125

When running 'gt handoff -m "message"' after successful MR submit, go panics with 'fatal error: all goroutines are asleep - deadlock\!' at handoff.go:125. The shutdown request still appears to be sent successfully but the command crashes. Stack trace shows issue is in runHandoff select statement.


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.


Create .runtime/ for town-level runtime state

Move ephemeral town state to .runtime/:
- Create ~/gt/.runtime/ directory structure
- Move daemon/state.json → .runtime/daemon.json
- Move deacon/heartbeat.json → .runtime/deacon.json
- Move .gastown/agent-state.json → .runtime/agent-requests.json
- Move .gastown/keepalive.json → .runtime/keepalive.json
- Update .gitignore to ignore .runtime/
- Update all code references


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.


Swarm: ephemeral rig support

PGT has ephemeral rigs for swarms - temporary worker groups that are destroyed after landing.

Missing Features:
- gt swarm init [--rig <name>|--git-url <url>] [--num-workers N]
- gt swarm worker add/remove/list <rig-id>
- gt swarm rigs - List ephemeral rigs
- gt swarm destroy <rig-id> - Destroy ephemeral rig

Mail orchestrator daemon

Background mail orchestrator daemon.

## Command
```
gt mail orchestrate [--interval N] [--once] [--verbose]
```

## Purpose
Background process that:
1. Monitors outbox for pending mail
2. Delivers to recipient inboxes
3. Handles offline recipients (retry later)
4. Cleans delivered messages from outbox

## Why Needed?
Current mail is synchronous. If recipient is offline or mailbox locked, send fails.
Orchestrator enables async delivery with retry.

## Implementation
```go
func (o *Orchestrator) Run(interval time.Duration) error {
    ticker := time.NewTicker(interval)
    for range ticker.C {
        o.processOutbox()
    }
}

func (o *Orchestrator) processOutbox() {
    // List outbox/*.json
    // For each, attempt delivery
    // On success, delete from outbox
    // On failure, increment retry count
}
```

## Outbox Structure
```
<town>/mayor/mail/outbox/
├── msg-abc123.json
└── msg-def456.json
```

## Lower Priority
Current synchronous delivery works. Orchestrator is optimization.

## Acceptance Criteria
- [ ] Background daemon mode
- [ ] Retry failed deliveries
- [ ] --once for single pass
- [ ] Configurable interval


Update templates for Propulsion Principle

Overhaul agent prompts to embody the Universal Gas Town Propulsion Principle:

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

Templates to update:
- [ ] deacon.md.tmpl - Check hook first, no decision logic
- [ ] polecat.md.tmpl - Propulsion startup, follow molecule
- [ ] witness.md.tmpl - Sling wisps when spawning agents
- [ ] refinery.md.tmpl - Accept slung epics

Key changes:
1. Remove 'should I run this?' decision points
2. Add 'check your hook' as step 1 of startup
3. Make molecule-following the default mode
4. Simplify - agents don't think, they execute

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


gt mq integration land: merge integration branch to main

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

Actions:
1. Verify all MRs targeting integration/<epic> are merged
2. Verify integration branch exists
3. Merge integration/<epic> to main (--no-ff)
4. Run tests on main
5. Push to origin
6. Delete integration branch
7. Update epic status

Options:
- --force: land even if some MRs still open
- --skip-tests: skip test run
- --dry-run: preview only

This creates a single merge commit for the entire epic's work.

Outpost integration tests: Mock and E2E testing

## Overview

Integration tests for the outpost system.

## Mock Outpost

```go
type MockOutpost struct {
    name        string
    maxWorkers  int
    spawnDelay  time.Duration
    spawnError  error
    workers     []*MockWorker
}

func (o *MockOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    if o.spawnError != nil {
        return nil, o.spawnError
    }
    time.Sleep(o.spawnDelay)
    worker := &MockWorker{id: uuid.New().String(), issue: issue}
    o.workers = append(o.workers, worker)
    return worker, nil
}
```

## Unit Tests

```go
func TestOutpostManager_SelectOutpost(t *testing.T) {
    // Test policy-based selection
}

func TestOutpostManager_SpawnWithRetry(t *testing.T) {
    // Test retry logic with transient failures
}

func TestCloudRunOutpost_CostTracking(t *testing.T) {
    // Test cost calculation and caps
}
```

## Integration Tests (with mocked Cloud Run)

```go
func TestCloudRunOutpost_Integration(t *testing.T) {
    // Start mock HTTP server
    server := httptest.NewServer(mockWorkHandler())
    defer server.Close()

    outpost := NewCloudRunOutpost(OutpostConfig{

File locking for concurrent access

Add file locking for concurrent access safety.

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

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

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

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

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

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

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

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

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

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


Worker prompting: Beads write access

Add beads write access section to polecat AGENTS.md.template.

## Beads Access Section for Prompting

```markdown
## Beads Access

You have **full beads access** - create, update, and close issues.

### Quick Reference

```bash
# View work
bd ready                    # Issues ready (no blockers)
bd list                     # All open issues
bd show <id>                # Issue details

# Create issues
bd create --title="Fix bug" --type=bug --priority=2
bd create --title="Add feature" --type=feature

# Update issues
bd update <id> --status=in_progress    # Claim work
bd close <id>                          # Mark complete

# Sync (required before merge!)
bd sync                     # Commit beads changes to git
```

### When to Create Issues

Create beads issues when you discover work that:
- Is outside your current task scope
- Would benefit from tracking
- Should be done by someone else

**Good examples**:
```bash
bd create --title="Race condition in auth" --type=bug --priority=1
bd create --title="Document API rate limits" --type=task --priority=3
```

**Don't create for**:
- Tiny fixes you can do in 2 minutes
- Vague "improvements" with no scope
- Work already tracked elsewhere

### Beads Sync Protocol

**CRITICAL**: Always sync beads before merging!

```bash
bd sync                    # Commits beads changes
git add .beads/
git commit -m "beads: sync"
```

If you forget to sync, beads changes are lost when session ends.
```

## Implementation

Add to AGENTS.md.template polecat section.

Work on ga-yp3: Polecat inbox system for reliable work assignment. This is P1 priority. See bd show ga-yp3 for full design spec.


Ephemeral polecats: spawn fresh, delete on completion

## Design Decision

Switch from pooled/idle polecats to ephemeral model:
- Spawn creates fresh worktree from main
- Polecat requests shutdown when done (bottom-up)
- Witness verifies handoff, kills session, deletes worktree
- No 'idle' state - polecats exist only while working

## Rationale

1. **Git worktrees are fast** - pooling optimization is obsolete
2. **Pooling creates maintenance burden:**
   - Git stashes accumulate
   - Untracked artifacts pile up
   - Branches drift from main
   - Beads DB gets stale
3. **PGT sync problems** came from persistent branches
4. **Support infrastructure exists** - Witness, Refinery, Mayor handle continuity
5. **Simpler mental model** - polecat exists = work in progress

## Lifecycle

```
Spawn:
  gt spawn --issue <id>
  → Creates fresh worktree: git worktree add polecats/<name> -b polecat/<name>
  → Initializes beads in worktree
  → Starts session, assigns work

Working:
  Polecat does task
  → Pushes to polecat/<name> branch
  → Submits to merge queue when ready

Completion (POLECAT-INITIATED):
  Polecat runs: gt handoff
  → Verifies git state clean
  → Sends mail to Witness: "Ready for shutdown"
  → Marks itself done, waits for termination

Cleanup (WITNESS-OWNED):
  Witness receives shutdown request
  → Verifies PR merged or in queue
  → Verifies no uncommitted changes
  → Kills session: gt session stop <rig>/<polecat>
  → Deletes worktree: git worktree remove polecats/<name>
  → Deletes branch: git branch -d polecat/<name>
  → Optionally: Notifies Mayor of completion
```

## Key Insight: Bottom-Up Shutdown

**Old model (wrong)**: Top-down batch shutdown - "cancel the swarm"
**New model (right)**: Bottom-up individual shutdown - polecat requests, Witness executes

This enables streaming:
- Workers come and go continuously
- No "swarm end" to trigger cleanup
- Each worker manages its own lifecycle
- Witness is the lifecycle authority

## Implementation

1. Add `gt handoff` command for polecats to request shutdown
2. Modify gt spawn to always create fresh worktree
3. Run bd init in new worktree (beads needs initialization)
4. Add shutdown request handler to Witness
5. Witness verifies handoff, then cleans up:
   - Kill session
   - Remove worktree
   - Delete branch
6. Remove 'idle' state from polecat state machine
7. Simplify gt polecat list (only shows active)

## Impact on Other Tasks

- gt-17r (Zombie cleanup): Becomes trivial - orphan worktrees
- gt-4my (Worker health): Simpler - no idle/stuck ambiguity
- gt-f9x.5/f9x.6 (Doctor): Fewer states to validate
- gt-eu9 (Witness handoff): Witness receives polecat shutdown requests


Engineer session restart protocol

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

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

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


Support numeric shortcuts in mail read (e.g., 'mail read 1')

When inbox shows numbered messages like:
* 1. gm-19b29031...  2025-12-16  mayor  Subject...
* 2. gm-19b26d51...  2025-12-16         Subject...

Users should be able to run 'gt mail read 1' instead of needing the full message ID 'gt mail read gm-19b29031f6a172206'.

Implementation:
- Track inbox message order in display
- Map numeric indices to actual message IDs
- Accept both numeric shortcuts and full IDs in 'mail read' command


gt crew at: auto-prime when exec'ing Claude in-session

When running 'gt crew at <name>' from inside the target session, we exec Claude directly. But this means we can't send 'gt prime' afterward since we ARE the process.

Possible solutions:
1. Claude startup hook that runs gt prime
2. Pass prompt as argument to claude CLI
3. Wrapper script approach

Related: crew resume prompt also can't be sent in this path.


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
```

## Parent
gt-4nn: Molecules epic


gt mq reject: manual MR rejection

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

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

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

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


Slim down rig root config.json to identity only

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


Deacon marching orders: pinned bead with rounds molecule

Create a pinned bead that defines the Deacon's rounds molecule - its "kernel".

## Concept

Like `gt prime` gives agents their context, a pinned bead gives the Deacon
its operating instructions. This bead defines:

1. The rounds molecule (steps to execute each wake)
2. Registered plugins (scheduled, event-triggered)
3. Configuration (timeouts, thresholds, escalation rules)

## Pinned Bead Structure

```yaml
# gt-deacon-kernel (pinned)
title: "Deacon Kernel Configuration"
type: policy
pinned: true

molecule: mol-deacon-rounds
  steps:
    - session-check: "Check context budget, cycle if needed"
    - health-scan: "Check Mayor, Witnesses, Refineries, Crew"
    - lifecycle: "Process pending lifecycle requests"
    - plugins: "Run due scheduled plugins"
    - events: "Process timer callbacks, event subscriptions"
    - complete: "Update heartbeat, return to wait"

plugins:
  scheduled:
    - name: beads-hygiene
      schedule: "0 2 * * *"  # 2 AM daily
    - name: branch-cleanup
      schedule: "0 4 * * 0"  # 4 AM Sundays

  event_triggers:
    - event: "issue.created"
      plugin: work-oracle
    - event: "mr.submitted"
      plugin: review-oracle

config:
  session_cycle_threshold_turns: 50
  session_cycle_threshold_hours: 4
  health_scan_timeout_seconds: 60
  plugin_timeout_minutes: 30
  escalation_after_failures: 3
```

## Reading Marching Orders

On wake, Deacon:
1. `bd show --pinned` to find the kernel bead
2. Parse molecule steps
3. Execute in order

## Updating the Kernel

To change Deacon behavior:
1. `bd update gt-deacon-kernel` with new config
2. Next wake cycle picks up changes
3. No code changes required

## Bootstrap

If no pinned bead exists, Deacon uses hardcoded defaults from DEACON.md.
First installation creates the pinned bead.

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

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

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

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

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

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

This is blocking the entire MQ pipeline.


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.

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.

Session pre-shutdown checks

Session stop should verify clean state before killing, like PGT.

## Pre-Shutdown Checks

### 1. Git Working Tree Clean
```go
func checkGitClean(clonePath string) error {
    // git status --porcelain
    // Fail if any output
}
```

### 2. All Commits Pushed
```go
func checkCommitsPushed(clonePath string) error {
    // git log origin/HEAD..HEAD
    // Fail if any unpushed commits
}
```

### 3. Assigned Issues Handled
```go
func checkIssuesHandled(polecat *Polecat) error {
    // If polecat.Issue != "", check if closed or reassigned
}
```

### 4. Beads Synced
```go
func checkBeadsSynced(clonePath string) error {
    // bd sync --status in clone directory
}
```

## Behavior on Failure
1. First attempt: Nudge worker to fix
2. Retry up to 3 times with delay
3. After retries: Escalate to Witness/Mayor

## Integration
Modify internal/session/manager.go Stop():
```go
func (m *Manager) Stop(polecat string, force bool) error {
    if !force {
        if err := m.runPreShutdownChecks(polecat); err != nil {
            return fmt.Errorf("pre-shutdown checks failed: %w", err)
        }
    }
    // existing stop logic
}
```

## Flags
- --force: Skip checks
- --grace-period N: Time to wait for fixes

## Dependencies
- Ties into gt-69l (hook system) - can be hook-based
- Ties into gt-f8v (Witness pre-kill verification)

## Acceptance Criteria
- [ ] Stop fails if uncommitted changes (without --force)
- [ ] Stop fails if unpushed commits
- [ ] Clear error messages with fix instructions
- [ ] --force bypasses all checks

gt mq list: doesn't show submitted MRs

After submitting MRs with gt mq submit, gt mq list gastown shows empty queue.

## Reproduction
1. gt mq submit --issue gt-h5n.5 --branch polecat/Scabrous
2. gt mq list gastown → (empty)
3. bd list --type=merge-request → shows the MR

## Expected
gt mq list should show submitted MRs

## MR example
gt-ts4u has rig: gastown in description, type=merge-request, status=open

Polecat CLAUDE.md: configure auto-approve for bd and gt commands

Polecats get stuck waiting for bash command approval when running
bd and gt commands. Need to configure Claude Code to auto-approve these.

Options:
1. Add allowedTools to polecat CLAUDE.md
2. Configure .claude/settings.json in polecat directory
3. Use --dangerously-skip-permissions flag (not recommended)

Should auto-approve:
- bd (beads commands)
- gt (gastown commands)
- go build/test
- git status/add/commit/push

Should still require approval:
- rm -rf
- Arbitrary commands outside project

Related to polecat prompting (gt-e1y, gt-sd6).


Merge execution: merge, test, push

Implement the actual merge execution.

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

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

Handle push failures with retry logic.
