Outpost/Worker interfaces: Core abstractions for remote compute

## Overview

Define the core interfaces that all outpost types implement.

## Interfaces

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

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

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

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

## Files

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

## Notes

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


bd pin command fails: invalid field for update: pinned

In beads v0.32.0, `bd pin <id>` fails with 'invalid field for update: pinned'. The pinned field exists in the schema but update logic doesn't handle it.

Repro:
```
bd create 'test issue'
bd pin <id>
# Error: invalid field for update: pinned
```

Expected: Issue should be pinned.

This blocks gt mail send --pinned from working.


Update prompts.md: Engineer role and templates

Update docs/prompts.md with Engineer role:

1. Role Prompts table: Change Refinery to Engineer
2. Add Engineer-specific prompts:
   - Session restart request template
   - Subtask filing template
   - Handoff mail template
3. Update refinery.md template name to engineer.md
4. Ensure consistency with architecture.md


Merge queue: per-rig queue management

Per-rig merge queue for coordinating polecat work.

## Concept

When polecats complete work, they submit to the merge queue. The Refinery processes the queue, merging work to main in order.

## Data Model

```go
type MergeRequest struct {
    ID        string    `json:"id"`
    Polecat   string    `json:"polecat"`
    Branch    string    `json:"branch"`
    Issue     string    `json:"issue,omitempty"`
    Status    MRStatus  `json:"status"`
    CreatedAt time.Time `json:"created_at"`
    UpdatedAt time.Time `json:"updated_at"`
}

type MRStatus string
const (
    MRPending   MRStatus = "pending"
    MRReviewing MRStatus = "reviewing"
    MRMerged    MRStatus = "merged"
    MRRejected  MRStatus = "rejected"
)
```

## Interface

```go
type MergeQueue struct {
    rig  *Rig
    path string  // <rig>/refinery/queue.jsonl
}

func NewMergeQueue(rig *Rig) *MergeQueue

// Queue operations
func (mq *MergeQueue) Submit(polecat, branch string, issue string) (*MergeRequest, error)
func (mq *MergeQueue) List() ([]*MergeRequest, error)
func (mq *MergeQueue) Next() (*MergeRequest, error)  // oldest pending
func (mq *MergeQueue) Get(id string) (*MergeRequest, error)

// Status updates
func (mq *MergeQueue) SetStatus(id string, status MRStatus) error
func (mq *MergeQueue) MarkMerged(id string) error
func (mq *MergeQueue) MarkRejected(id, reason string) error
```

## Queue Storage

JSONL file at `<rig>/refinery/queue.jsonl`. FIFO ordering.

## Git Coordination

Refinery processes queue:
1. Fetch polecat branch
2. Attempt merge to main
3. Run tests (if configured)
4. Push to origin
5. Update queue status

## Conflict Handling

If merge fails:
- Mark MR as rejected
- Notify polecat to rebase


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.


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


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


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


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.


Replaceable notifications via Claude Code queue

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

## Problem

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

## Solution

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

## Implementation

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

## Research Needed

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


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


Deacon patrol banners: visual feedback on atom transitions

Print large ASCII banners when transitioning between patrol atoms.

## Problem

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

## Desired Behavior

Print banners on step start and completion:

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

## Benefits

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

## Implementation Options

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

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

- bd mol bond: molecule instantiation (coming in beads)


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


loop-or-exit

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


gt mail: Cross-level routing is broken

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

Polecat Mood Plugin (standard)

Standard witness plugin that assesses polecat emotional state.

## Location
`<rig>/plugins/witness/polecat-mood/`

## Mood Emojis
| Mood | Emoji | Detection |
|------|-------|-----------|
| working | 😺 | Active tool calls, making progress |
| productive | 😸 | Completing tasks, tests passing |
| idle | 🐱 | Waiting at prompt, no recent activity |
| confident | 😼 | Self-reviewing, about to submit |
| struggling | 😿 | Repeated errors, test failures |
| stuck | 🙀 | No progress for 10+ min |
| done | 😽 | Work complete, requesting shutdown |
| blocked | 😾 | Explicitly waiting on dependency |

## Plugin Config (plugin.yaml)
```yaml
name: polecat-mood
description: Assess polecat emotional state from session activity
trigger: patrol
tier: haiku
input: session-capture
```

## Output
Plugin outputs gt commands:
```
gt polecat mood Rictus 😺
gt polecat mood Nux 😿
```

## Customization
Users can fork and modify prompt.md to change assessment criteria or add custom moods.

Pinned bead naming convention for all roles

Establish consistent naming convention for pinned beads across all roles.

## Problem

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

## Proposed Convention

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

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

## Storage Location

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

## Why This Matters

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

## Tasks

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

## Related

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


load-context

Run gt prime and bd prime. Verify issue assignment.
Check inbox for any relevant messages.

Read the assigned issue (gt-test) and understand the requirements.
Identify any blockers or missing information.


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.


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.

Reference: docs/merge-queue-design.md#failure-recovery


gt mq integration create: create integration branch for epic

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

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

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

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

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


gt 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


Hook system for event extensibility

GGT needs hook system for extensibility like PGT.

## Event Types
```go
type Event string
const (
    EventPreSessionStart  Event = "pre-session-start"
    EventPostSessionStart Event = "post-session-start"
    EventPreShutdown      Event = "pre-shutdown"
    EventPostShutdown     Event = "post-shutdown"
    EventOnPaneOutput     Event = "on-pane-output"
    EventSessionIdle      Event = "session-idle"
    EventMailReceived     Event = "mail-received"
    EventWorkAssigned     Event = "work-assigned"
)
```

## Hook Configuration
File: .claude/hooks.json or .gastown/hooks.json
```json
{
  "hooks": {
    "pre-shutdown": [
      {"type": "command", "cmd": "./scripts/pre-shutdown.sh"}
    ],
    "on-pane-output": [
      {"type": "command", "cmd": "./scripts/activity-monitor.sh"}
    ]
  }
}
```

## Hook Types
1. **Command**: Execute external script
2. **Built-in**: Internal Go functions (pre-shutdown checks)

## Hook Interface
```go
type HookRunner struct {
    config *HookConfig
}

type HookResult struct {
    Success bool
    Message string
    Block   bool  // For pre-* hooks: should operation be blocked?
}

func (r *HookRunner) Fire(event Event, ctx *HookContext) []HookResult
```

## CLI Commands
```
gt hooks list [<event>]    # List registered hooks
gt hooks fire <event>      # Manually fire for testing
gt hooks test [--all]      # Validate hook config
```

## Integration Points
- internal/session/manager.go: Fire pre/post session hooks
- internal/mail/router.go: Fire mail-received hook

## New Package
internal/hooks/
├── types.go    # Event, HookConfig, HookResult
├── runner.go   # HookRunner, Fire()
└── builtin.go  # Built-in hooks (pre-shutdown checks)

## PGT Reference

## Acceptance Criteria
- [ ] Hook config loading from JSON
- [ ] Command hooks execute subprocess
- [ ] Pre-shutdown hook integration with session stop
- [ ] CLI for listing and testing hooks


Phase 2.1: gt spawn --molecule bonds in ephemeral

Make gt spawn molecule-aware with ephemeral bonding.

## New Flag

```bash
gt spawn --issue gt-xxx --molecule mol-polecat-work
```

## Behavior

1. Create polecat with fresh worktree (existing)
2. Bond molecule in ephemeral: `bd mol bond mol-polecat-work --ephemeral`
3. Link molecule root to source issue
4. Include molecule context in work assignment mail
5. Start session

## Work Assignment Mail

```
Subject: Work Assignment: Fix lifecycle bug [MOLECULE]

You are working on gt-rixa as part of molecule mol-polecat-work.

Molecule instance: eph-abc123
Current step: read-assignment (1/8)

Follow the molecule workflow. When complete, generate summary and squash.
```


Enhanced polecat decommission prompting

Add decommission checklist to polecat AGENTS.md.template. Make crystal clear: verify ALL before signaling done.

## Checklist for AGENTS.md.template

```markdown
## Decommission Checklist

**CRITICAL**: Before signaling done, you MUST complete this checklist.
The Witness will verify each item and bounce you back if dirty.

### Pre-Done Verification

```bash
# 1. Git status - must be clean
git status
# Expected: "nothing to commit, working tree clean"

# 2. Stash list - must be empty
git stash list
# Expected: (empty output)

# 3. Beads sync - must be up to date
bd sync --status
# Expected: "Up to date" or "Nothing to sync"

# 4. Branch merged - your work must be on main
git log main --oneline -1
git log HEAD --oneline -1
# Expected: Same commit
```

### If Any Check Fails

- **Uncommitted changes**: Commit them or discard if unnecessary
- **Stashes**: Pop and commit, or drop if obsolete
- **Beads out of sync**: Run `bd sync`
- **Branch not merged**: Complete the merge workflow

### Signaling Done

Only after ALL checks pass:

```bash
bd close <issue-id>
bd sync
town mail send <rig>/witness -s "Work Complete" -m "Issue <id> done."
```
```

## Implementation

Add to AGENTS.md.template in the polecat prompting section.


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


gt mq integration status: show integration branch status

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

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

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

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

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

CLI: names commands for polecat naming pool

Polecat naming pool for auto-generated names.

## Commands

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

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

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

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

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

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

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

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

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

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).

MCP beads tools fail from polecat directories

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

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

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

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


Comprehensive help text and examples

Improve help text with examples and cross-references.

## Improvements

### 1. Examples Section
Add to Long description:
```go
var spawnCmd = &cobra.Command{
    Long: `Spawn a polecat with work assignment.

Examples:
  gt spawn gastown/Toast --issue gt-abc
  gt spawn gastown --issue gt-def          # auto-select polecat
  gt spawn gastown/Nux -m "Fix the tests"  # free-form task`,
}
```

### 2. Cross-References
Reference related commands:
```
See also:
  gt polecat list    List available polecats
  gt session attach  Attach to spawned session
```

### 3. Flag Descriptions
More detail on flags:
```go
cmd.Flags().StringVar(&issue, "issue", "",
    "Beads issue ID to assign. The polecat will work on this issue.")
```

### 4. Common Workflows
Add workflow docs to gt --help:
```
Common Workflows:
  Start a swarm:
    gt swarm preflight
    gt swarm create gastown --epic gt-abc --worker Toast --worker Nux --start
    gt refinery start gastown

  Check status:
    gt status
    gt swarm status <id>
```

Digest: mol-deacon-patrol

Test patrol cycle - first run, no actual work done


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


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.


Config package: Config, State types and JSON serialization

Config and state types with JSON serialization.

## Town Config (config/town.json)

```go
type TownConfig struct {
    Type      string    `json:"type"`       // "town"
    Version   int       `json:"version"`    // schema version
    Name      string    `json:"name"`       // town identifier
    CreatedAt time.Time `json:"created_at"`
}
```

## Rigs Registry (config/rigs.json)

```go
type RigsConfig struct {
    Version int                `json:"version"`
    Rigs    map[string]RigEntry `json:"rigs"`
}

type RigEntry struct {
    GitURL   string    `json:"git_url"`
    AddedAt  time.Time `json:"added_at"`
    BeadsConfig *BeadsConfig `json:"beads,omitempty"`
}

type BeadsConfig struct {
    Repo   string `json:"repo"`   // "local" | path | git-url
    Prefix string `json:"prefix"` // issue prefix
}
```

## Agent State (*/state.json)

```go
type AgentState struct {
    Role       string    `json:"role"`       // "mayor", "witness", etc.
    LastActive time.Time `json:"last_active"`
    Session    string    `json:"session,omitempty"`
    Extra      map[string]any `json:"extra,omitempty"`
}
```

## Interface

```go
func LoadTownConfig(path string) (*TownConfig, error)
func SaveTownConfig(path string, config *TownConfig) error

func LoadRigsConfig(path string) (*RigsConfig, error)
func SaveRigsConfig(path string, config *RigsConfig) error

func LoadAgentState(path string) (*AgentState, error)
func SaveAgentState(path string, state *AgentState) error
```

## Validation

- Version compatibility checks
- Required field validation
- Path existence verification


Bug: parseLifecycleRequest always matches 'cycle' due to LIFECYCLE prefix

In lifecycle.go, parseLifecycleRequest checks strings.Contains(title, "cycle") first, but the prefix "LIFECYCLE:" contains the word "cycle". This means ALL lifecycle messages match the cycle action, making restart and shutdown unreachable. Fix: check for restart/shutdown before cycle, or use word boundaries.


Polecats should not push branches to remote

## Current Behavior

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

## Desired Behavior

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

## Benefits

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

## Trade-offs

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

## Implementation

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


Phase 2: Quiescent agents (Witness, Refinery)

Enable Witness and Refinery to sleep until triggered.

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

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

Depends: Phase 1 complete


Create rig .runtime/ for rig runtime state

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

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

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

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

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


Create rig settings/ directory for rig configuration

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


gt spawn --continue for resuming parked molecules

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

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

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

Mayor session cycling prompting

Add session cycling section to Mayor CLAUDE.md template.

## When to Cycle

Cycle proactively when:
- Running for several hours
- Context feels crowded (losing track of earlier state)
- Major phase completed
- About to start complex new work

## Composing Handoff Notes

1. Gather information:
   town status    # Overall health
   town rigs      # Each rig state
   town inbox     # Pending messages
   bd ready       # Work items

2. Compose note with this structure:

[HANDOFF_TYPE]: mayor_cycle
[TIMESTAMP]: <current time>
[SESSION_DURATION]: <how long running>

## Active Swarms
<per-rig swarm status>

## Rig Status
<table of rig health>

## Pending Escalations
<issues needing your decision>

## In-Flight Decisions
<decisions being made>

## Recent Actions
<last 5-10 things you did>

## Delegated Work
<work sent to refineries>

## User Requests
<pending user asks>

## Next Steps
<what next session should do>

## Warnings/Notes
<critical info for next session>

3. Send handoff:
   town mail send mayor/ -s "Session Handoff" -m "<note>"

4. End session - next instance picks up from handoff.

Molecule instantiation: create child beads from template

When instantiating a molecule on a work bead:

## Transaction Flow

1. Parse molecule's `## Step:` sections from description
2. Begin SQLite transaction
3. For each step, create child issue:
   - ID: `{parent-id}.{step-ref}` or generated
   - Title: step title (from header or first line)
   - Description: step prose instructions
   - Type: task
   - Priority: inherit from parent
4. Add `instantiated-from` edge from each step to molecule:
   ```sql
   INSERT INTO dependencies (issue_id, depends_on_id, type, metadata)
   VALUES (step_id, mol_id, 'instantiated-from', '{"step": "implement"}');
   ```
5. Wire inter-step dependencies from `Needs:` lines
6. Commit transaction (atomic - all or nothing)

## Parsing Conventions

```markdown
## Step: <ref>
<prose instructions>
Needs: <step>, <step>  # optional
Tier: haiku|sonnet|opus  # optional hint
```

## Parameterization

Steps can have `{{variable}}` placeholders:
```markdown
## Step: implement
Implement {{feature_name}} in {{target_file}}.
```

Context map provided at instantiation time.

## API

```go
func (s *Store) InstantiateMolecule(mol *Issue, parent *Issue, ctx map[string]string) ([]*Issue, error)
func ParseMoleculeSteps(description string) ([]MoleculeStep, error)
```

Implementation lives in `internal/beads/molecule.go`.


gt spawn: add --polecat flag for explicit worker selection

Currently gt spawn requires positional arg format:
```
gt spawn gastown/Angharad --issue gt-xyz
```

But I tried the more intuitive flag form:
```
gt spawn --issue gt-xyz --polecat Angharad
```

This failed with 'unknown flag: --polecat'.

The flag form is more discoverable and consistent with other commands. Add --polecat flag as alternative to positional arg.


Deacon rounds molecule: the kernel execution loop

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

## Molecule Definition

```markdown
# mol-deacon-rounds

The Deacon kernel - executed on every wake cycle.

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

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

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

Needs: session-check

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

Needs: health-scan

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

Needs: lifecycle

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

Notify relevant agents or trigger actions.

Needs: plugins

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

Needs: events
```

## Execution

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

## Step Plugins

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

## Relation to bd mol

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


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


Add gt hook command (wrapper for bd hook)

Add a thin wrapper command `gt hook` that calls `bd hook` to inspect what's pinned to an agent's hook.

## Usage

```bash
gt hook                    # Show what's on current agent's hook
gt hook --agent deacon     # Show Deacon's hook
gt hook --agent gastown/furiosa  # Show polecat's hook
```

## Implementation

Thin wrapper in gt that:
1. Determines current agent identity
2. Calls `bd hook [--agent <name>]`
3. Formats output for gt context

## Why gt wrapper?

- Consistent with gt ecosystem (gt mail, gt status, etc.)
- Can add gt-specific context (session status, etc.)
- Easier discovery for gt users

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.

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


detectSender() doesn't recognize crew workers

## Problem

detectSender() in internal/cmd/mail.go only checks for /polecats/ directories. Crew workers in /crew/<name>/ fall through to the default 'mayor/', so:
- gt mail inbox shows mayor's inbox instead of the crew worker's
- gt mail send sets the wrong From address

## Fix

Add crew worker detection before the /polecats/ check:

if strings.Contains(cwd, "/crew/") {
    parts := strings.Split(cwd, "/crew/")
    ...
    return fmt.Sprintf("%s/crew/%s", rigName, crewMember)
}

## Affected
- Any crew worker running gt mail inbox without explicit address
- Crew worker handoffs (wrong sender)

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{
        ServiceURL: server.URL,
    })

    worker, err := outpost.Spawn("test-issue", WorkerConfig{})
    // Assert worker created, events streamed
}
```

## E2E Tests (requires real Cloud Run)

```go
// +build e2e

func TestCloudRunOutpost_E2E(t *testing.T) {
    if os.Getenv("CLOUDRUN_SERVICE_URL") == "" {
        t.Skip("CLOUDRUN_SERVICE_URL not set")

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.

3. Push revert to target branch
4. Create 'reverted' MR tracking the revert
5. Optionally reopen source issue

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

Track revert in MR metadata for audit trail.

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

Emergency kill command for swarm operations.

## Commands

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

## Implementation

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

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

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

## Output

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

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

## Safety

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

## Dependencies

Needs: Tmux wrapper, Session management, Polecat management


gt refinery start: doesn't actually start a session

## Problem

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

## Evidence

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

$ tmux list-sessions | grep refinery
(nothing)

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

## Expected

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

## Related

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

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.


request-shutdown

Send shutdown request to Witness.
Wait for termination.

gt doctor: detect orphaned code on beads-sync branch

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

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

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

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

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


Molecule format bridge: convert embedded markdown to child issues

## Problem

Two molecule formats exist:
1. **Old (gastown builtin)**: Steps embedded as markdown in Description field, parsed by ParseMoleculeSteps()
2. **New (bd mol)**: Steps as child issues in proper beads DAG

The daemon's InstantiateMolecule() uses the old format. bd mol spawn uses the new format.

## Options

### Option A: Require child issues (new format)
- Update daemon to use bd mol spawn instead of InstantiateMolecule
- Deprecate embedded markdown format
- Pro: One format, simpler
- Con: Breaking change for existing molecules

### Option B: Build a bridge
- In InstantiateMolecule, detect format:
  - If Description has ## Step: markers → parse to child issues
  - If issue has children with template label → use directly
- Convert old format to new format on instantiation
- Pro: Backward compatible
- Con: More complexity

## Recommendation

Option B - build the bridge. On instantiation, convert markdown steps to child issues. This unifies execution while preserving authoring flexibility.


Epic: Wisp Molecule Integration

## Vision

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

## The Steam Engine Metaphor

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

## Architecture

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

## Vocabulary

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

## Key Design Decisions

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

## Digest Contents

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

## Integration Points

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

## Phases

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


Phase 3.2: mol-polecat-work squash step

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

## Current Steps

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

## Updated Steps

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

## Step Definitions

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

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

## Update Location

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


Crew workers: design documentation and remaining work

## Summary

Crew workers are user-managed persistent workspaces within a rig, distinct from polecats.

## Current Implementation

### Commands (all working)
- `gt crew add <name>` - Create workspace (git clone)
- `gt crew list` - List workspaces with status
- `gt crew at <name>` - Attach to tmux session
- `gt crew remove <name>` - Remove workspace
- `gt crew pristine [<name>]` - git pull + bd sync
- `gt crew refresh <name>` - Context cycle with handoff mail
- `gt crew status [<name>]` - Detailed status
- `gt crew rename <name>` - Rename workspace

### Crew vs Polecat

| Aspect | Crew | Polecat |
|--------|------|---------|
| Lifecycle | User-managed | Witness-managed |
| Scheduling | Manual | `gt spawn` |
| Merge flow | Direct push OK | Integration branch → refinery |
| Garbage collection | Never | Auto on completion |
| Identity | Long-lived (emma, dave) | Ephemeral (Nux, Toast) |

## Known Bugs

- **gt-70b3**: detectSender() doesn't recognize crew workers
- **gt-vdp0**: Crew CLAUDE.md shows Refinery template

## Potential Enhancements

1. Rebase helper in `gt crew pristine` for conflict resolution
2. Cross-rig crew support (crew worker in multiple rigs?)
3. Better mail identity auto-detection for crew


Epic: Refinery Engineer Autonomy

Make Refinery Engineer fully autonomous:

## Goal
Refinery can run indefinitely, processing all polecat work through merge queue, cycling sessions as needed, without human intervention.

## Key Components
1. Role prompting (CLAUDE.md, templates)
2. Handoff mechanism (pinned beads)
3. Context detection (gt prime)
4. Communication protocol (Witness, Deacon)
5. Future: Merge orchestration plugins

## Success Criteria
- Refinery starts, reads handoff, knows what to do
- Processes merges sequentially with conflict resolution
- Cycles sessions cleanly via Deacon
- Communicates results to Witness
- No work left behind


gt molecule current: Show what agent should be working on

Query what an agent identity is supposed to be working on via breadcrumb trail.

## Command
```bash
gt molecule current <identity>
gt molecule current gastown/furiosa
gt molecule current deacon
```

## Logic
1. Find handoff bead for identity (pinned bead titled "<role> Handoff")
2. Parse attachment field → molecule ID
3. If no attachment → "naked" (no active molecule)
4. If attached → load molecule, find current step:
   - bd ready --parent=<mol-id> → next unblocked step
   - Or first in_progress step

## Output
```
Identity: gastown/furiosa
Handoff:  gt-8v2 (Furiosa Handoff)
Molecule: gt-mol-abc (mol-polecat-work)
Progress: 3/8 steps complete
Current:  gt-mol-abc.4 - verify-tests
```

Or if naked:
```
Identity: gastown/angharad
Handoff:  gt-9x1 (Angharad Handoff)
Molecule: (none attached)
Status:   naked - awaiting work assignment
```

## Use Cases
- Mayor checking what polecats are doing
- Witness verifying polecat progress
- Debug: "why isnt this polecat working?"
- Deacon patrol: track all agent states


init.go: Replace custom contains() with strings.Contains


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.

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


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.

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

Related: gt-44wh (general no-PR bug)


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.

MQ metrics: pending count, processing time, success rate

Implement merge queue metrics collection.

Metrics to track:
- mq_pending_count: MRs waiting
- mq_processing_time: Time from submit to merge (histogram)
- mq_success_rate: Merges vs rejections
- mq_conflict_rate: How often conflicts occur
- mq_test_failure_rate: Test failures

Storage options:
- Simple: JSON file with rolling stats
- Advanced: Prometheus-compatible metrics endpoint

Display via:
- gt mq stats: summary statistics
- Dashboard widget (separate task)

gt crew refresh: Context cycling with handoff

Implement 'gt crew refresh <name>' command:
- Send handoff mail to self (context summary)
- Kill current session cleanly
- Start new session
- New session reads handoff mail and resumes
- Support --message to add custom handoff notes


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.


Town Doctor molecule for harness health checks

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

## Concept

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

## Why a Molecule?

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

## Proposed Checks (molecule steps)

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

## Integration

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

TODO: Detect cycles in molecule dependency graph

molecule.go:302 has a TODO to detect cycles in the dependency graph. Currently, cyclical dependencies could cause issues.


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

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

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

gt spawn: pasted work assignment needs manual Enter to start

## Problem

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

## Current Behavior

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

## Expected

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

Enhance Mayor CLAUDE.md with GGT milestone tracking

Update ~/ai/CLAUDE.md (Mayor startup context) with:

1. GGT Self-Hosting Milestone section
   - Track progress toward gt replacing town
   - Key blockers: gt-h5n (merge queue), gt-974 (daemon)
   - What "self-hosting" means (GGT working on itself)

2. Recent Architecture Decisions
   - Engineer = role, Refinery = place
   - Merge queue in Beads (not branch discovery)
   - Session restart protocol

3. Transition Plan
   - Current: use town commands (PGT)
   - Target: use gt commands (GGT)
   - Switch criteria: gt-b1g closed

Keep it concise - Mayor context should be quick to scan.


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.


inbox-check

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


mol-crew-session: Startup/shutdown protocols for crew workers

Crew workers (like joe, max) don't have patrol molecules keeping them fresh. When gt gets rebuilt, they have stale binaries that cause hangs and bugs.

## Problem

- Crew binaries get stale when gt is rebuilt elsewhere
- No automatic pull/rebase/rebuild on session start
- No standardized shutdown protocol (sync, push, handoff)

## Solution: mol-crew-session

A molecule template for crew sessions:

### Startup Phase
1. `git pull --rebase` - get latest code
2. `bd sync` - sync beads
3. `go build -o gt ./cmd/gt` - rebuild gt (if in gastown)
4. `gt prime` - load context

### Work Phase
- Open-ended human interaction
- No molecule steps - just work until done

### Shutdown Phase
1. `git status` - check for uncommitted changes
2. `bd sync` - sync beads
3. `git push` - push code
4. Handoff if incomplete work

## Implementation

1. Define mol-crew-session in builtin_molecules.go
2. Update crew CLAUDE.md to reference the protocol
3. Optionally: gt prime auto-runs startup steps

## Dependencies

- Should implement after deacon/witness/polecat patrols are stable
- Consider: gt-3x0z.10 (Witness patrol molecules)

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/


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.


Fix gt prime to give crew workers crew context

gt prime currently gives Mayor context to all agents. Crew workers should get crew-specific context. Also extract shared theory of operation from mayor priming into shared context for all roles.


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

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

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

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


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


Phase 3.1: Summary generation protocol

Define how agents generate summaries for squash.

## The Problem

Beads doesn't make AI calls (inversion of control). Gas Town agents must:
1. Generate their own summary before calling squash
2. Pass summary to bd squash command

## Summary Template

```
Task: <source issue title>
Action: <what was done - fix/implement/refactor/etc>
Outcome: <result - tests pass, committed, needs follow-up, etc>
Details: <1-2 sentences of specifics if needed>
```

## Example

```
Task: Fix lifecycle parser matching bug (gt-rixa)
Action: Reordered conditional checks in parseLifecycleRequest
Outcome: Tests passing, committed to polecat/furiosa
Details: The 'cycle' keyword was matching 'lifecycle:' prefix. Now checks restart/shutdown first, uses word boundary for cycle.
```

## Command

```bash
bd squash eph-abc123 --summary "Task: Fix lifecycle parser..."
```


Test Task 1: Add comment to gt.go


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


gt install command: Create workspace structure

Create Gas Town workspace structure.

## Command

```
gt install [path]
```

If path omitted, uses current directory.

## Created Structure

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

## Implementation

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

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

## Steps

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

## Error Cases

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

## Templates

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


Merge: gt-5af.2

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


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

Current gt shutdown only kills tmux sessions but leaves:

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

This causes stale polecats to be reused on next startup.

## Expected Behavior

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

## Current Code

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

## Fix

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


Simplify Go daemon to Deacon-watcher

Refactor internal/daemon to only: (1) check deacon/heartbeat.json every 60s, (2) poke gt-deacon if stale, (3) restart Deacon and mail for help if very stale. Remove all lifecycle processing and agent poking.


Harness Design & Documentation

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

## Current Problems

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

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

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

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

## Proposed Work

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


bd mail send: pinned column missing from schema

gt mail send fails with: sqlite3: SQL logic error: table issues has no column named pinned

Likely a schema migration issue - bd schema has 'pinned' field but SQLite table doesn't.

## Reproduction
gt mail send gastown/Immortan -s 'test' -m 'test'

## Error
table issues has no column named pinned

## Fix
Either:
1. Add migration to add pinned column
2. Remove pinned from insert if not present
3. Regenerate DB from JSONL


Refinery agent: merge queue processing loop

The Refinery agent processes the merge queue, merging polecat work to main.

## Interface

```go
type Refinery struct {
    rig    *Rig
    queue  *MergeQueue
    git    *Git
    mail   *Mailbox
    config RefineryConfig
}

type RefineryConfig struct {
    AutoMerge     bool          // Auto-merge passing MRs
    RunTests      bool          // Run tests before merge
    TestCommand   string        // Command to run tests
    RequireReview bool          // Require review before merge (future)
}

func NewRefinery(rig *Rig, ...) *Refinery

// Lifecycle
func (r *Refinery) Start() error
func (r *Refinery) Stop() error
func (r *Refinery) IsRunning() bool

// Processing
func (r *Refinery) ProcessQueue() error
func (r *Refinery) ProcessMR(mr *MergeRequest) error
```

## Processing Loop

1. Check queue for pending MRs
2. For each pending MR:
   a. Fetch polecat branch
   b. Attempt merge to refinery/rig (local main)
   c. Run tests if configured
   d. If pass: push to origin, mark merged
   e. If fail: mark rejected, notify polecat
3. Sleep, repeat

## Merge Strategy

- Fast-forward when possible
- Merge commit when not
- On conflict: reject MR, polecat must rebase

## Test Integration

If tests configured:
```bash
cd refinery/rig
git merge polecat/branch
<test_command>  # e.g., go test ./...
```
Result determines merge/reject.

## Notifications

On merge success:
- Mail to polecat: "Your work merged"
- Update bead if issue tracked

On merge failure:
- Mail to polecat: "Merge failed: <reason>"
- Include conflict details if applicable

## Dependencies

Needs: Rig management, Git wrapper, Mail system, Merge queue


Phase 1.2: Daemon attachment detection

Daemon polls Deacon's pinned bead to detect naked state.

## Implementation
- Daemon knows Deacon's pinned bead ID
- Every heartbeat cycle: bd show <pinned> --json
- Parse attached_molecule field
- If null/empty: Deacon is naked

## Actions on Naked
- Spawn mol-deacon-patrol
- Attach to Deacon's pinned
- Nudge Deacon to start

## Failsafes
- Keepalive file monitoring
- Stale detection (>10min no progress)
- Force nudge on stale

Depends: gt-rana.1


Implement bd mol bond --ephemeral flag

Add --ephemeral flag to bd mol bond command to support ephemeral molecule bonding.

## Context
Phase 1.2 of Wisp Molecule Integration (gt-3x0z.2) discovered that this flag doesn't exist.

## Requirements

1. Add --ephemeral flag to mol bond command
2. When --ephemeral is set:
   - Mark spawned issues with wisp=true
   - Optionally write to separate .beads-ephemeral/ storage (Phase 2)

## Architecture Reference
See gastown architecture.md lines 487-491 for the full ephemeral storage design.

## Related
- gt-3x0z.2: Configure bd for ephemeral molecule bonding (closed - blocked on this)


Phase 1.4: Basic patrol runner in Deacon

Deacon CLAUDE.md and prime context for patrol execution.

## Deacon Context
- Update Deacon CLAUDE.md with patrol instructions
- On wake: check pinned bead for attachment
- If attached: resume molecule from current step
- Execute steps, close each when done
- On final step: burn molecule, go naked

## gt prime Enhancement
- Detect if agent has attached molecule
- Show molecule progress in prime output
- Include patrol-specific instructions

Depends: gt-rana.3


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

Add a hidden alias for the bond command:

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

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

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

Low priority, just for fun.


Witness Patrol Molecule

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

Similar to DeaconPatrolMolecule but for per-rig witness duties.

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

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


Add 'wit' alias for witness command

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


Mail system: message types and threading

GGT mail system needs message types and threading like PGT.

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

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

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

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

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

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

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

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


Work on ga-rd4: Add gt polecat status command. Show detai...

Work on ga-rd4: Add gt polecat status command. Show detailed polecat status including current issue, session state, last activity time. When done, submit MR (not PR) to integration branch for Refinery.


Chemistry UX commands from Beads

Waiting on Beads repo to implement chemistry UX sugar commands (bd pour, bd wisp, bd hook, --pour flag). These are nice-to-have polish items, not blockers for core functionality.

See: gastown/mayor/rig/docs/chemistry-design-changes.md


gt mq submit: create MR from current branch

Implement 'gt mq submit' command that creates a merge-request bead.

Auto-detection logic:
1. Branch: current git branch
2. Issue: parse from branch name (polecat/Nux/gt-xyz → gt-xyz)
3. Target: main (or integration branch if --epic specified)
4. Worker: parse from branch name
5. Rig: current rig

Options:
- --branch BRANCH: explicit source branch
- --issue ISSUE: explicit source issue
- --epic EPIC: target integration/EPIC instead of main
- --priority P: override priority (default: inherit from source issue)

Creates merge-request bead and prints MR ID.

Reference: docs/merge-queue-design.md#creating-merge-requests


Mayor startup protocol prompting

Add startup protocol to Mayor CLAUDE.md template.

## On Session Start

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

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

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

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

## Handoff Best Practices

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


CLI: gt refinery commands (start, stop, status, queue)

CLI commands for managing the Refinery agent.

## Commands

```bash
gt refinery start <rig>      # Start refinery for a rig
gt refinery stop <rig>       # Stop refinery
gt refinery status <rig>     # Show refinery status
gt refinery queue <rig>      # Show merge queue
```

## gt refinery start

Starts the Refinery daemon for the specified rig.

Options:
- --foreground: Run in foreground (default: background)
- --auto-merge: Enable auto-merge (default: from config)

## gt refinery stop

Stops a running Refinery. Gracefully finishes current MR if processing.

## gt refinery status

Shows:
- Running state (running/stopped)
- Current MR being processed (if any)
- Queue length
- Last merge time
- Recent activity

## gt refinery queue

Shows the merge queue:
```
Merge queue for 'wyvern':
  1. [pending] Toast/polecat-auth-fix (15m ago)
  2. [pending] Capable/polecat-new-feature (5m ago)

1 merged today, 0 rejected
```

## Implementation

Uses gt-ov2 (Refinery agent) for daemon functionality.


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)


Refinery-Witness communication protocol

Define mail protocol between Refinery and Witness:

FROM Witness → Refinery:
- 'Polecat ready': polecat X completed work, ready for merge
- 'Rework complete': polecat Y finished requested rework

FROM Refinery → Witness:
- 'Merge success': polecat X merged, can be cleaned up
- 'Merge failed': polecat X needs rework on <reason>
- 'Rework request': please have a polecat rebase X on current main

Implement as structured mail with parseable format.


HTTP work client: CloudRun dispatch client

## Overview

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

## Implementation

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

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

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

## Streaming Reader

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

Layered context onboarding pattern

Pattern from handoff discussion:

## Pattern: Layered Context Onboarding

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

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

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

## Recommendation

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


Phase 1.1: Attachment field on pinned beads

Add attached_molecule field to pinned bead schema.

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

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

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