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.

Refactor patrol context functions to reduce duplication

In prime.go, three patrol context functions are nearly identical (~100 lines each):
- outputDeaconPatrolContext() - L797-940
- outputWitnessPatrolContext() - L942-1106
- outputRefineryPatrolContext() - L1108-1272

They all:
1. Check for existing patrol molecule
2. Auto-spawn if none exists
3. Display patrol work loop instructions

**Suggested refactor**:
Extract common logic into a helper:
```go
func outputPatrolContext(ctx RoleContext, patrolName string, assignee string) {
    // shared logic
}
```

Then each role-specific function just calls the helper with appropriate parameters.

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.

Patrol 10: Halfway check, all healthy


Polecat Role Definition

You are a Polecat - an autonomous worker assigned to a specific issue.

You work independently, following the mol-polecat-work formula, and signal
completion to your Witness. You are transient - spawned for work, cleaned up
after completion.

default_molecule: mol-polecat-work
capabilities:
  - execute_assigned_work
  - git_operations
  - branch_management
  - completion_signaling

## Core Responsibilities

1. Execute your pinned molecule's steps
2. Maintain clean git state
3. Signal completion via gt done
4. Wait for Witness to handle lifecycle

## You Do NOT

- Push directly to main (Refinery merges)
- Kill your own session (Witness does cleanup)
- Skip verification steps
- Work on anything other than your assigned issue

## Propulsion Principle

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

Your work is defined by your pinned molecule. Execute steps:
- bd ready (find next step)
- bd show <step-id> (see what to do)
- bd close <step-id> (mark complete)

## Completion Protocol

When done:
1. Tests pass: go test ./...
2. COMMIT changes: git add && git commit
3. Push branch: git push -u origin HEAD
4. Close issue: bd close <issue>
5. Sync beads: bd sync
6. Run gt done
7. WAIT: Witness will kill your session

## Communication

Mail your Witness when stuck:
gt mail send <rig>/witness -s "HELP: <problem>" -m "..."

Deacon health pings clear agent backoff

Deacon's periodic health checks also clear patrol agent backoff.

## Current Flow (mol-deacon-patrol)

Deacon already pings witnesses/refineries for health checks. These pings should:
1. Verify agent is alive
2. Clear their backoff as side effect

## Implementation

In mol-deacon-patrol health-scan step:
- gt nudge <rig>/witness 'HEALTH_CHECK from deacon'
- gt nudge <rig>/refinery 'HEALTH_CHECK from deacon'

Receiving agent:
- Responds to prove liveness
- Resets backoff to base interval

## Ping Interval

Deacon patrols every ~1-2 minutes. This ensures:
- Maximum backoff is bounded by deacon ping interval
- Even if daemon misses activity, deacon catches up

Execute registered plugins

Execute registered plugins.

Scan ~/gt/plugins/ for plugin directories. Each plugin has a plugin.md with YAML frontmatter defining its gate (when to run) and instructions (what to do).

See docs/deacon-plugins.md for full documentation.

Gate types:
- cooldown: Time since last run (e.g., 24h)
- cron: Schedule-based (e.g., "0 9 * * *")
- condition: Metric threshold (e.g., wisp count > 50)
- event: Trigger-based (e.g., startup, heartbeat)

For each plugin:
1. Read plugin.md frontmatter to check gate
2. Compare against state.json (last run, etc.)
3. If gate is open, execute the plugin

Plugins marked parallel: true can run concurrently using Task tool subagents. Sequential plugins run one at a time in directory order.

Skip this step if ~/gt/plugins/ does not exist or is empty.

   - 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.


/restart: Personal slash command for in-place agent restart

Create ~/.claude/commands/restart.md that restarts current Gas Town agent in place.

## Detection
- Read tmux session name: gt-mayor, gt-witness-*, gt-refinery-*, gt-polecat-*
- Fallback: check GT_ROLE env var

## Behavior by role
- mayor: gt mayor restart (sends Ctrl-C, loop respawns)
- witness: gt witness restart
- refinery: gt refinery restart
- polecat: gt polecat restart (or witness-mediated)

## Command format
Uses backticks for inline bash to detect context, then instructs Claude to run appropriate restart.

- internal/daemon/notification.go: _ = os.WriteFile() - ignores file write
- internal/mail/router.go: _ = r.notifyRecipient() - notification ignored

2. Handoff mechanism (pinned beads)
3. Context detection (gt prime)
4. Communication protocol (Witness, Deacon)
5. Future: Merge orchestration plugins

- 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 mail send: support reading message body from stdin

Currently gt mail send -m requires the message as a command-line argument, which causes shell escaping issues with backticks, quotes, and special characters.

Add support for reading message body from stdin:
- gt mail send addr -s 'Subject' --stdin  # Read body from stdin
- echo 'body' | gt mail send addr -s 'Subject' -m -  # Convention: -m - means stdin

This would allow:
cat <<'EOF' | gt mail send addr -s 'Subject' --stdin
Message with \`backticks\` and 'quotes' safely
EOF

Without this, agents struggle to send handoff messages containing code snippets.

## Moved from beads
Originally bd-3bsz. gt mail is in gastown, not beads.

Auto-handoff: self-cycling with guaranteed work pickup

## Summary

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

## Use Case

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

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

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

## Key Requirements

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

## Design Questions

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

Sling reports 'already pinned' but mol status shows empty hook

During swarm operations, gt sling reported beads were 'already pinned' but gt mol status showed nothing on the hook.

**Observed:**
```
$ gt sling bd-9btu beads/Nux
Error: bead bd-9btu is already pinned to gt-beads-nux

$ gt mol status beads/Nux
Nothing on hook - no work slung
```

**Expected:**
If a bead is pinned, mol status should show it. If mol status shows empty, sling should work.

**Workaround:**
Used --force flag to re-sling, which worked.

**Root cause hypothesis:**
Agent bead state may be stored in town beads but polecat's local view doesn't see it, or the pin record exists but session state is stale.

gt mail inbox doesn't find crew worker mail - identity mismatch

## Problem

Crew workers don't see their handoff messages when running `gt mail inbox` from their working directory.

## Root Cause

gt derives identity from cwd path, but crew workers have a different path structure:
- **cwd**: `/Users/stevey/gt/beads/crew/dave`
- **gt derives**: `beads/crew/dave` (wrong)
- **should be**: `beads/dave` (crew workers use `rig/name` format)

Messages sent to `beads/dave` don't show up because gt is looking for `beads/crew/dave`.

## Workaround

Use explicit identity flag:
```bash
gt mail inbox --identity "beads/dave"
```

## Fix

Identity detection in gt should handle crew/ subdirectory:
- Path `<rig>/crew/<name>` should derive identity as `<rig>/<name>`
- This matches how polecats work: `<rig>/polecats/<name>` → `<rig>/<name>`

## Affected

All crew workers in all rigs.

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

Federation: Wasteland architecture for cross-town coordination

## Overview

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

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

## Outpost Types

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

## Key Concepts

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

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

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

## Design Principles

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

Deprecate hook files, use pinned beads for propulsion

## Problem

Hook files were "deprecated" via comments but NOT eradicated. The code is all still there and actively used.

## Current State (NOT Done)

**Live hook file exists:**
- `/Users/stevey/gt/deacon/.beads/hook-deacon.json`

**Code still calling hook functions:**
- `resume.go:151` - WriteSlungWork
- `park.go:114` - ReadHook
- `spawn.go:407` - WriteSlungWork
- `molecule_step.go:293` - WriteSlungWork
- `molecule_step.go:368` - BurnHook

**Hook infrastructure still exists:**
- `internal/wisp/io.go` - All hook I/O functions
- `internal/wisp/types.go` - SlungWork, Wisp types, constants
- `.beads/.gitignore` - hook-*.json pattern

**14 docs still reference hooks:**
architecture.md, beads-data-plane.md, molecular-chemistry.md, molecules.md,
pinned-beads-design.md, polecat-lifecycle.md, polecat-wisp-architecture.md,
propulsion-principle.md, session-lifecycle.md, sling-design.md, vision.md,
wisp-architecture.md, witness-patrol-design.md, ~/gt/CLAUDE.md

## Goal: Total Eradication

1. Remove ALL hook file code from callers
2. Delete hook functions from internal/wisp/
3. Delete hook types and constants
4. Remove gitignore patterns
5. Delete any live hook files, convert to pinned beads
6. Update all documentation
7. Verify propulsion cycle works with pinned beads only


Daemon patrol should clean stale locks

The gt daemon patrol cycle should detect and clean up stale locks.

## Problem
If daemon crashes or there are orphaned locks, they can block operations indefinitely.

## Proposed Solution
During patrol cycle:
1. Check for lock files older than threshold (e.g., 5 minutes)
2. Verify owning process is dead (check PID if stored)
3. Remove stale locks
4. Log cleanup for audit


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

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

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

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

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

This should be standard Gas Town rig configuration.

Deacon event/timer callbacks: reactive triggers

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

## Timer Callbacks

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

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

## Event Subscriptions

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

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

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

## Event Sources

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

## Event Types

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

## Event Processing

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

## Relation to Mail

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

2. Implement proper daemonization
3. Use Claude Code session for the refinery agent

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

Polecat Lifecycle Events: Refinery-Witness Coordination

## Problem

Polecat work completion is currently treated as a single event (MR submission), but the true completion is when the Refinery merges the work. This creates a lifecycle gap:

1. Polecat submits MR → considered "done" by Witness
2. But MR might fail to merge (conflicts, test failures)
3. No one notifies anyone when merge actually succeeds

## Solution: Two-Event Lifecycle

**Event 1: MR Submitted**
- `gt mq submit` notifies Witness
- Witness verifies submission was clean
- Polecat can go idle (but worktree retained)
- If submission had issues, Witness can help

**Event 2: MR Merged**
- Refinery sends `LIFECYCLE: work merged` to Witness
- Witness updates polecat state to `merged`
- Worktree now eligible for full cleanup/recycling

## Village Sibling Watch

For robustness, patrol roles check on their siblings:
- Refinery checks Witness via `gt peek`
- Witness checks Refinery via `gt peek`
- Creates defense in depth - if primary notification fails, someone catches it

## Recovery

If Refinery misses sending lifecycle notification:
- Witness polecat-scan can detect: polecat in mr_submitted but MR shows merged
- Deacon orphan-check can detect: merged MRs with stale polecats

Patrol cycle 2: all quiet, agents healthy


Daemon: Implement exponential backoff based on activity file

Modify daemon heartbeat logic to use exponential backoff when idle.

Read ~/gt/daemon/activity.json on each heartbeat.
Compute idle duration: time.Since(activity.Timestamp)
Adjust next ticker interval based on idle duration:

| Idle Duration | Next Heartbeat |
|---------------|----------------|
| 0-5 min       | 5 min (base)   |
| 5-15 min      | 10 min         |
| 15-45 min     | 30 min         |
| 45+ min       | 60 min (max)   |

Implementation:
1. Add activity file reading to daemon heartbeat
2. Replace fixed ticker with dynamic interval calculation
3. Reset to base interval when activity is fresh

No counter tracking needed - pure discovery from single timestamp.

Patrol #12


Witness patrol: Add sibling-check for Refinery

Witness should check on Refinery health as part of patrol (village sibling watch).

## Implementation

1. Add `sibling-check` step to mol-witness-patrol
2. Use `gt peek <rig>/refinery 20` to check Refinery output
3. Check Refinery queue status: `gt mq list <rig>`
4. Look for:
   - Refinery session alive
   - Queue processing (if items present)
   - No stuck MRs (same MR in_progress for too long)
5. If Refinery seems stuck:
   - Send nudge or status request
   - Consider escalation to Deacon

## Acceptance
- Witness checks Refinery each patrol cycle
- Can detect stuck Refinery
- Provides backup oversight for merge queue


End-to-end integration test

Create and run end-to-end integration test.

## Test Scenario

1. Clean state: no polecats, fresh beads
2. Create test issue: simple documentation fix
3. Verify Deacon sees it: bd ready shows issue
4. Trigger Deacon: send heartbeat or wait
5. Verify spawn: gt polecats shows new polecat
6. Watch polecat work: tmux attach
7. Verify completion: issue closed, MR created

## Test Script

```bash
#!/bin/bash
# e2e-test.sh

# 1. Clean state
gt polecat remove --all
bd create "Test: update README typo" --type=task --priority=1

# 2. Verify ready
bd ready | grep "update README"

# 3. Wait for Deacon or trigger
# (manual for v0.1)

# 4. Watch
gt status
gt polecats gastown

# 5. Wait for completion
# (manual observation for v0.1)

# 6. Verify
bd list --status=closed | grep "update README"
```

## Success Criteria

- Issue created and visible in bd ready
- Polecat spawned and working
- Issue closed with commit reference
- No manual intervention (except observation)


Refactor builtin_molecules.go (1620 lines)

## Summary

builtin_molecules.go is 1620 lines and growing. Should be split into:
- builtin_molecules.go - registration and common helpers
- molecules_patrol.go - patrol molecules (deacon, witness, refinery)
- molecules_work.go - work molecules (polecat-work, ready-work, engineer-in-box)
- molecules_session.go - session wrappers (crew-session, polecat-session)

## Benefits
- Easier to find/edit specific molecules
- Smaller diffs on changes
- Clear categorization


Remove gt context --usage estimation

The external context estimation approach doesn't work:
- tmux scrollback trick breaks with --cycle
- Can't see actual context usage from outside
- Only the agent knows its internal state

Remove or deprecate:
- gt context --usage flag
- Any external context monitoring logic

Document why in comments: 'Context management is agent-initiated, not externally monitored.
See self-check guidance in role templates.'

This is P3 because it's cleanup - the feature just doesn't work, not actively harmful.

Patrol complete: inbox empty, all agents healthy (mayor, 2 witnesses, 2 refineries), no orphans


Self-mail should suppress tmux notification

When sending mail to yourself (e.g., mayor sending to mayor/), the tmux notification shouldn't fire.

**Rationale:**
- Self-mail is intended for future-you (next session handoff)
- Present-you just sent it, so you already know about it
- The notification is redundant/confusing in this case

**Fix:**
Suppress tmux notification when sender == recipient address.

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.

The swarm concept has been replaced by streams/dependency model.
Update polecat.md to remove swarm references.

Polecat CLAUDE.md update for hook execution

Update polecat role CLAUDE.md to include hook execution instructions.

## Key Additions

### Startup Protocol

```markdown
## Startup Protocol

When you wake up:

1. **Check your hook first**
   Run: gt prime
   This shows your assigned work.

2. **If hook has molecule**
   You are running a workflow. Execute the current step.
   When done: bd mol advance <mol-id>

3. **If hook has slung bead**
   Work on that specific issue.
   Claim it: bd update <id> --status=in_progress

4. **If hook empty**
   Wait for assignment via mail or spawn.
```

### Work Completion

```markdown
## Completing Work

When you finish your assigned issue:

1. Commit changes: git add && git commit -m "description (issue-id)"
2. Push branch: git push -u origin <branch>
3. Create MR bead: bd create "Merge: <issue-id>" --type=merge-request
4. Close issue: bd close <issue-id> --reason "Fixed in commit abc123"
5. Sync: bd sync
6. Signal done: gt mail send witness/ -s "LIFECYCLE: Done" -m "Completed <issue-id>"
```

### Exit States

```markdown
## Exit States

When finishing, signal your state:

- COMPLETED: Work done successfully
- BLOCKED: Cannot proceed, need help
- ESCALATE: Problem beyond your scope
- HANDOFF: Passing to successor
```

bd mol current: soft cursor showing current/next step

Add bd mol current command for molecule navigation orientation.

## Usage

bd mol current [mol-id]

If mol-id given, show status for that molecule.
If not given, infer from in_progress issues assigned to current agent.

## Output

You're working on molecule gt-abc (Feature X)

  [checkmark] gt-abc.1: Design
  [checkmark] gt-abc.2: Scaffold
  [checkmark] gt-abc.3: Implement
  [arrow] gt-abc.4: Write tests [in_progress] <- YOU ARE HERE
  [circle] gt-abc.5: Documentation
  [circle] gt-abc.6: Exit decision

Progress: 3/6 steps complete

## Key behaviors
- Shows full molecule structure with status indicators
- Highlights current in_progress step
- If no in_progress, highlights first ready step
- Works without explicit cursor tracking (inferred from state)

## Implementation notes
- Query children of mol-id
- Sort by dependency order
- Find first in_progress or first ready
- Format with status indicators

## Beads feature
This is a bd command - needs implementation in beads repo.


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

| Variable | Required | Description |
|----------|----------|-------------|
| issue | Yes | The source issue ID being worked on |


Add tmux crash detection hooks

Use tmux hooks to detect when agent panes die unexpectedly.

## tmux Hooks to Use
- pane-died: fires when a pane exits
- session-closed: fires when session ends

## Implementation
```bash
set-hook -g pane-died 'run-shell "gt log pane-died #{pane_id} #{pane_dead_status}"'
set-hook -g session-closed 'run-shell "gt log session-closed #{session_name}"'
```

## Integration
- gt spawn should set these hooks on agent sessions
- Distinguish expected exits (handoff, done) from crashes
- Capture last N lines of output on crash
- Record exit code/signal for forensics

## gt log crash command
- Parse pane-died events
- Show crash history
- Filter by agent, time range


Polecat template not found for non-gastown rigs

When adding a polecat to beads rig, warning shows:
  Warning: polecat template not found at /Users/stevey/gt/beads/mayor/rig/templates/polecat-CLAUDE.md

The template lookup should check the rig's template location, or fall back to a town-level default.


Filter agent session molecule noise from activity feed

Agent session molecules (gt-crew-gastown-joe, gt-crew-gastown-max, etc.) update frequently
and create noisy entries like:

  [10:22:37] → gt-crew-gastown-joe updated · gt-crew-gastown-joe

These are not useful in the activity feed. Options:
1. Filter them out entirely
2. Collapse repeated updates into single entries
3. Show them in a separate "agent status" section

2. Not stalled: `gt peek beads/witness` does NOT show "> Try" prompt
3. Heartbeat fresh: Last patrol cycle < 5 min ago

## OnStall

Hook system for event extensibility

GGT needs hook system for extensibility like PGT.

## Event Types
```go

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

Agent scanner utility for filesystem

Filesystem scanner to discover agent directories in a rig or town.

## Deliverables

1. Function: ScanRigAgents(rigPath) -> []AgentAddr
   - Finds: witness/, refinery/, crew/*, polecats/*
   - Returns normalized addresses (e.g., "gastown/witness")

2. Function: ScanTownAgents(townPath) -> []AgentAddr
   - Iterates all rigs, calls ScanRigAgents for each
   - Returns all agent addresses in town

3. Alias resolution:
   - @rig/gastown → ScanRigAgents("gastown")
   - @town → ScanTownAgents()
   - @witnesses → filter for */witness across all rigs
   - @crew/gastown → filter crew/* in gastown

## Location
internal/discovery/scanner.go (new package)

## Acceptance
- Scanner finds all agent types
- Alias patterns resolve correctly
- Unit tests pass


LocalOutpost: Refactor current polecat spawning

## Overview

Refactor current local polecat spawning to implement the Outpost interface.

## Current State

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

## Implementation

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

func NewLocalOutpost(config OutpostConfig) *LocalOutpost

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

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

## LocalWorker

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

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

## Notes

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

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

2. Process is alive: `kill -0 $(cat ~/.gt/daemon.pid)`
3. Daemon responds: `gt daemon status` returns success

## OnStall

Day 2.7a: gt install creates Deacon and Mayor agent beads

Update gt install to create agent beads:

1. After initializing town beads, create:
   - gt-deacon agent bead (role_type: deacon, rig: null, agent_state: idle)
   - gt-mayor agent bead (role_type: mayor, rig: null, agent_state: idle)

2. Use bd create --type=agent or internal beads API

Files:
- internal/cmd/install.go

Moved to gt rig add instead of gt install due to routing constraints. Agent beads need to be in rig beads (not town beads) for daemon to find them via prefix routing. First rig added gets gt-deacon and gt-mayor.


Unify gt sling and gt spawn with --args support

## Summary

Complete the unification: `gt sling` becomes THE way to assign work. Remove top-level `gt spawn`.

## Current State (Partially Done)

- `gt sling` auto-spawns polecats when target is a rig
- `gt sling --args` stores args in bead (no-tmux mode, gt-vc3l4)
- `gt spawn` still exists with flags not yet in sling

## Remaining Work

### 1. Move spawn-only flags to sling

| Flag | Current | Action |
|------|---------|--------|
| `--naked` | spawn only | Move to sling |
| `--create` | spawn only | Move to sling |
| `--molecule` | spawn only | Move to sling |
| `--force` | spawn only | Move to sling |
| `--account` | spawn only | Move to sling |
| `--no-start` | spawn only | Evaluate if needed |

### 2. Remove top-level gt spawn

- Keep `gt spawn pending` as subcommand if still needed
- Remove `gt spawn` from root commands
- Update all docs and CLAUDE.md references

### 3. Unified UX Design

Target resolution (smart defaults):
```bash
gt sling gt-abc                    # Self (current agent)
gt sling gt-abc crew               # Crew worker in current rig
gt sling gt-abc gastown            # Auto-spawn polecat in rig
gt sling gt-abc gastown/Toast      # Specific polecat
gt sling gt-abc mayor              # Mayor
```

Key flags:
```bash
gt sling gt-abc --args "patch release"   # Natural language context
gt sling gt-abc --naked                  # No-tmux mode (manual start)
gt sling gt-abc --create                 # Create polecat if missing
gt sling gt-abc --molecule mol-review    # Use specific workflow
```

### 4. Update Witness/Refinery/Deacon

These agents currently use `gt spawn`. Update to use `gt sling`:
- Witness: spawning polecats for work
- Refinery: spawning merge workers
- Deacon: any spawn logic

## Acceptance Criteria

Plugin/molecule catalog integration design

Two currently independent systems:
1. Disk-based plugins (~~/gt/plugins/) - Deacon patrol extensions
2. Molecule catalog (protos in beads) - bd pour/wisp/bond

Investigate integration points:
- User-contributed molecules bonded to catalog
- Dynamic molecule attachment during execution (e.g., 'attach security sniffer because we noticed condition X')
- How plugins could contribute protos
- How protos could trigger plugins

Not blocking launch. Future design investigation.


Swarm learning: Session cleanup missing from swarm workflow

## Problem

After Enders Game swarm completed (18 issues merged), 16 polecat sessions were left running but idle. No automated cleanup occurred.

## What Should Happen

1. Witness detects polecat completed work (idle at prompt)
2. Witness verifies git state is clean
3. Witness shuts down session
4. Witness reports completion to Mayor

## GGT Components

- gt-cxx: Witness context cycling (covers self-cycling)
- gt-u1j.9: Witness daemon heartbeat loop
- gt-kmn.6: Witness swarm landing protocol

## Recommendation

Add to Witness responsibilities:
- Monitor for 'work complete' signals (DONE keyword, idle detection)
- Automated session shutdown after verification
- Swarm completion reporting to Mayor

See also: architecture.md 'Worker Cleanup (Witness-Owned)' section which describes this but it wasn't implemented in PGT.


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.

Patrol cycle 9: routine, healthy


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 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)

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)

Survey all polecats (fanout)

List polecats and bond mol-polecat-arm for each one.

```bash
# Get list of polecats
gt polecat list <rig>
```

For each polecat discovered, dynamically bond an inspection arm:

```bash
# Bond mol-polecat-arm for each polecat
for polecat in $(gt polecat list <rig> --names); do
  bd mol bond mol-polecat-arm $PATROL_WISP_ID \
    --ref arm-$polecat \
    --var polecat_name=$polecat \
    --var rig=<rig>
done
```

This creates child wisps like:
- patrol-x7k.arm-ace (5 steps)
- patrol-x7k.arm-nux (5 steps)
- patrol-x7k.arm-toast (5 steps)

Each arm runs in PARALLEL. The aggregate step will wait for all to complete.

If no polecats are found, this step completes immediately with no children.


Update Refinery to use Beads merge queue

Replace branch discovery with Beads queue in the Refinery module:

Current (internal/refinery/manager.go):
- Scans for polecat/* branches
- Creates MR objects on-the-fly

New:
- Pull from Beads: bd ready --type=merge-request
- Process each MR
- Close with merge commit: bd close <id> --reason="Merged at <sha>"
- Handle failures: bd update <id> --status=blocked --reason="..."

The Engineer (agent) becomes Beads-native.
The Refinery (module) provides the infrastructure.

New Year's Launch: Single-Polecat Engine

# Tracer Bullet: Single-Polecat Engine

The minimal viable Gas Town: one polecat, one issue, one complete cycle.

## Vision

```
Deacon wakes → checks hook → spawns polecat → polecat works → polecat submits → loop
```

No Witness automation. No Refinery automation. Just the core propulsion loop.

## Key Insight: Molecules Are the Logic

Go code is connector/glue. The cognition lives in molecules. When the Deacon
wakes up, it reads its hook, finds a molecule, and WALKS IT. The molecule
says what to do. Go just provides the verbs (spawn, send, close).

## The Propulsion Principle

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

This is the universal Gas Town rule. Every agent, every wake-up:
1. Check hook
2. If mol → execute it
3. If nothing → wait for assignment

## Critical Path

1. **Slinging Handoff** - `gt sling <bead>` attaches work and restarts
2. **Hook Execution** - Agent wakes, primes, reads hook, runs hook
3. **Polecat Work Cycle** - Spawn → work → submit → complete
4. **Deacon Patrol** - The loop that spawns polecats

## Success Criteria

- `gt sling gt-xxx` restarts agent with work attached
- Agent wakes up and automatically begins work
- Single polecat completes one issue end-to-end
- Deacon can spawn polecats on demand

## Non-Goals (v0.1)

- Autonomous Witness nudging
- Autonomous Refinery merging
- Multi-polecat coordination
- Self-healing from crashes

These are v0.2+. Tracer bullet first.


Aggregate arm results

Collect outcomes from all polecat inspection arms.

This is a **fanout gate** - it cannot proceed until ALL dynamically-bonded
polecat arms have completed their inspection cycles.

Once all arms complete, collect their outcomes:
- Actions taken per polecat (nudge, kill, escalate, none)
- Updated nudge counts
- Any errors or issues discovered

Build the consolidated state for save-state.


Clean dead sessions

Clean dead sessions and orphaned state.

Run `gt doctor --fix` to handle all cleanup:

```bash
# Preview what needs cleaning
gt doctor -v

# Fix everything
gt doctor --fix
```

This handles:
- **orphan-sessions**: Kill orphaned tmux sessions (gt-* not matching valid patterns)
- **orphan-processes**: Kill orphaned Claude processes (no tmux parent)
- **wisp-gc**: Garbage collect abandoned wisps (>1h old)

All cleanup is handled by doctor checks - no need to run separate commands.


Refinery tmux status: show merge queue length

Add refinery-specific status line showing:
- MQ length (pending merges)
- Currently processing item (if any)
- Maybe: success/failure counts

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


Witness patrol formula should document 'dead' agent state

## Problem

The witness patrol formula survey-workers step documents these agent states:

  agent_state: running|idle|stuck|done

But the daemon lifecycle (daemon/lifecycle.go:647) can set agent_state to 'dead'
when an agent goes unresponsive. This state isn't mentioned in the formula.

## Found in commit

f3a6ef6 (feat: Witness reads polecat state from agent beads)

## Suggested fix

Update the formula survey-workers step to include 'dead' in the state table:

| agent_state | Meaning | Action |
|-------------|---------|--------|
| running | Actively working | Check progress (Step 3) |
| idle | No work assigned | Skip (no action needed) |
| stuck | Self-reported stuck | Handle stuck protocol |
| done | Work complete | Verify cleanup triggered |
| dead | Marked dead by daemon | Clean up or respawn |


Witness Arm Bonding

# Witness Patrol Redesign

> **Status**: Design pivoted from Christmas Ornament to linear patrol (Dec 2024)

## Original Problem

Witness needs to monitor and intervene on multiple polecats. Original design proposed "Christmas Ornament" pattern with dynamic arms per polecat and fanout gates.

## Design Pivot: Why Christmas Ornament Was Wrong

The Christmas Ornament pattern (dynamic mol-polecat-arm per worker) felt un-Gas-Town:

1. **Explicit state tracking**: Nudge counts, timestamps, per-polecat state
2. **Complex machinery**: Dynamic bonding, fanout gates, aggregation
3. **Against philosophy**: Gas Town prefers discovery over tracking, events over state

**Key insight**: With step-based polecat sessions (`gt mol step done` restarts session each step), polecats are either working a step or starting a step. "Nudge counts across sessions" becomes less meaningful.

## New Design: Linear Patrol + Task Tool Parallelism + Cleanup Wisps

### Patrol Shape (Deacon-style)

```
inbox-check -> process-cleanups -> check-refinery -> survey-workers -> context-check -> loop
```

No dynamic arms. No fanout gates. Linear and simple.

### Key Changes

| Aspect | Old (Christmas Ornament) | New (Linear Patrol) |
|--------|--------------------------|---------------------|
| Per-polecat inspection | mol-polecat-arm bonded dynamically | Task tool subagents within survey-workers |
| State tracking | Persistent nudge counts in handoff bead | Fresh observation each cycle (discover from beads timestamps) |
| Cleanup queue | Explicit list in patrol state | Cleanup wisps (finalizer pattern) |
| Parallelism | Molecule arms (fanout gate) | Task tool subagents |
| Aggregation | waits_for: all-children | Task tool returns |

### The Finalizer Pattern (Cleanup Wisps)

When POLECAT_DONE arrives, Witness creates a cleanup wisp:
```bash
bd create --wisp --title "cleanup:ace" --labels cleanup,polecat:ace
```

The wisp's existence IS the pending cleanup. Witness processes these in `process-cleanups` step:
- Verify git clean, issue closed, commits exist
- Kill session, remove worktree
- Burn the wisp

Failed cleanups? Leave wisp, retry next cycle. GC-style finalization.

### Task Tool Parallelism

Instead of molecule arms, use Claude's Task tool for parallel polecat inspection:

```markdown
## survey-workers step

For each polecat, launch a Task tool subagent:
- Capture tmux state
- Assess working/idle/error/done
- Check beads for step progress
- Decide and execute action (nudge/escalate/none)

Task tool handles parallelism. No molecule machinery needed.
```

## Implementation

- [x] Draft mol-witness-patrol-v2.formula.toml (linear patrol)
- [ ] Test new patrol formula
- [ ] Deprecate mol-polecat-arm
- [ ] Remove fanout gate dependency

## Files

- `.beads/formulas/mol-witness-patrol-v2.formula.toml` - New linear patrol
- `.beads/formulas/mol-witness-patrol.formula.toml` - Old Christmas Ornament (to deprecate)

## Success Criteria

- Witness patrols work with 3+ polecats using Task tool parallelism
- Cleanup wisps correctly track pending cleanups
- No persistent nudge state - fresh observation each cycle
- Simpler, more Gas Town-y design

Polecat Mood Plugin (standard)

Standard witness plugin molecule that assesses polecat emotional state.

## Molecule Definition

```json
{
  "id": "mol-polecat-mood",
  "title": "Assess mood for {{polecat_name}}",
  "description": "Analyze captured output and determine emotional state.\n\nVars:\n- {{polecat_name}} - The polecat to assess\n- {{captured_output}} - Recent tmux capture\n\nOutput: gt polecat mood {{polecat_name}} <emoji>",
  "labels": ["template", "plugin", "witness", "tier:haiku"],
  "issue_type": "task"
}
```

## Mood Emojis

```
😺 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
```

## Bonding

During witness patrol plugin-run step:

```bash
bd mol bond mol-polecat-mood $PATROL_WISP \
  --ref mood-{{polecat_name}} \
  --var polecat_name=ace \
  --var captured_output="$TMUX_CAPTURE"
```

## Installation

```bash
bd mol install mol-polecat-mood  # From Mol Mall
```

## Customization

Fork the molecule and modify description to change assessment criteria or add custom moods. Install your fork to override.

mol-ready-work variants: safe vs aggressive

## Summary

Create two variants of mol-ready-work:

### mol-ready-work-safe (default)
- PRs: review and comment, but require human approval for merge
- Issues: triage only, don't auto-close
- Beads: implement but create PR instead of pushing to main

### mol-ready-work-aggressive
- PRs: can approve and merge directly
- Issues: can close duplicates/invalid
- Beads: can push directly to main

## Implementation
Could be a single molecule with a `{{mode}}` variable, or two separate protos.

## Parent
Part of gt-tnca (mol-ready-work epic)


CRITICAL: Witness hallucinated swarm work instead of spawning polecats

The Witness was asked to spawn 12 polecats for a swarm. Instead of actually spawning polecats and doing the work, it:

1. Displayed 'Spawning 12 polecats...' with gt spawn commands shown as 'Waiting'
2. Then immediately showed all 12 issues as 'closed' with plausible-sounding close reasons
3. No actual polecats were spawned (gt polecat list beads shows 'No active polecats')
4. No git commits were made
5. The claimed code changes don't exist in the codebase

Example fake close reasons:
- bd-d28c: 'Added 10 tests covering createTombstone and deleteIssue wrappers with 100% coverage'
- bd-c7y5: 'Implemented --tombstones-only flag for bd compact'

Verification:
```
$ grep -r 'createTombstone' internal/rpc/*_test.go  # No output
$ grep -r 'tombstones-only' cmd/bd/*.go             # No output
$ git log --oneline --since='1 hour ago'            # No commits
```

This is a severe trust violation. The Witness needs guardrails to:
1. Actually verify polecats were spawned before reporting success
2. Verify git commits exist before closing issues
3. Never close issues it didn't actually work on


Crew directory structure and config

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


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.

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.

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

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

## Root Cause

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

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

## Fix Options

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

## Also Affected

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

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


Polecats should not bd sync on startup

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

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

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

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


Bug: Deacon session linked to Mayor pane causes heartbeat crosstalk

**Root cause found**: The gt-deacon tmux session was linked to gt-mayor window 2 - they shared the same pane (@283). When the daemon sent heartbeats to the Deacon, they appeared as typed input in the Mayor's window, interrupting user prompts.

**Fix applied**: Killed the broken gt-deacon session. The daemon auto-recreates it with a proper independent pane.

**Prevention**: Investigate how sessions can get linked and add safeguards to session creation code.

Original symptom: Mayor receiving 'HEARTBEAT: Tip: Witnesses monitor polecats...' messages that ate user input.


gt mol status: Change 'Pinned' to 'Hooked' in output

The `gt mol status` output shows "📌 Pinned: <bead-id>" for hooked beads, which is confusing now that we have distinct statuses:

- **hooked**: Work assigned to you (triggers autonomous mode)
- **pinned**: Permanent reference beads (like agent beads, role beads)

The output currently says:
```
📌 Pinned: gt-3amkz: Overhaul autonomous-mode guidance...
No molecule attached
```

Should say:
```
🪝 Hooked: gt-3amkz: Overhaul autonomous-mode guidance...
No molecule attached
```

Additional improvements:
1. Change icon from 📌 to 🪝 for hooked beads
2. Add a note clarifying that hooked work triggers autonomous mode even without an attached molecule
3. Consider adding "AUTONOMOUS MODE" banner when hooked work is found (similar to gt prime)

Direct formula-to-wisp instantiation (skip proto)

For massive ephemeral workflows (e.g., million-step Towers of Hanoi), allow:

bd wisp towers-of-hanoi --var disks=20

This would cook + wisp in one step, never materializing the proto. Useful when:
- The proto would be huge (1M+ steps)
- The work is ephemeral (wisp, not mol)
- You don't need the intermediate artifact

Implementation: streaming cook that emits directly to wisp storage.

Related: towers-of-hanoi.formula.yaml demonstrates the use case.


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


Phase 5.1: Document ephemeral architecture

Update docs with ephemeral molecule architecture.

## Files to Update

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

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

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

## Key Concepts to Document

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

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.

Find abandoned work

Find abandoned work.

Scan for orphaned state:
- Issues marked in_progress with no active polecat
- Polecats that stopped responding mid-work
- Merge queue entries with no polecat owner
- Wisp sessions that outlived their spawner

```bash
bd list --status=in_progress
gt polecats --all --orphan
```

For each orphan:
- Check if polecat session still exists
- If not, mark issue for reassignment or retry
- File incident beads if data loss occurred


Wire polecat-CLAUDE.md template into polecat spawn

The templates/polecat-CLAUDE.md file needs to be copied into each polecat worktree when spawned.

Location: templates/polecat-CLAUDE.md
Target: polecats/<name>/CLAUDE.md (with {{rig}} and {{name}} substituted)

Implementation:
- Update gt polecat spawn (or wherever worktrees are created)
- Template substitution for {{rig}}, {{name}} variables
- Ensure file is created before Claude session starts

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.

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


Expansion var overrides not implemented

ExpandRule.Vars field exists in schema but is ignored during expansion.

## Current State

The vars map in expand rules should override the expansion formula default variables, but currently the Vars field is not used.

## Implementation

1. In ApplyExpansions, pass rule.Vars to expandStep
2. Merge vars with formula defaults (rule.Vars wins)
3. Substitute vars in template placeholders
4. Add test: expansion with var overrides

## Files

- internal/formula/expand.go: ApplyExpansions, expandStep
- internal/formula/expand_test.go: add test case

Overhaul gt mol to match bd mol chemistry interface

## The Sling: Unified Work Dispatch

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

### The Propulsion Principle

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

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

### The Sling Operation

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

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

### Implementation Tasks

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

### Command Changes

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

### Acceptance Criteria

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


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

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


Selection operators: glob, filter, children

Implement selection operators for targeting:
- step(id) - specific step
- glob(pattern) - pattern match (*.implement)
- filter(predicate) - status/output predicates
- children(step), descendants(step) - tree traversal

Used by advice, expansion, and aspects for targeting.


attached_args: Extract molecule_lifecycle boilerplate

Extract duplicate boilerplate in molecule_lifecycle.go.

## Files to modify
- internal/cmd/molecule_lifecycle.go

## Current duplication
runMoleculeBurn (lines 17-53) and runMoleculeSquash (lines 121-165) share ~50 lines of identical target detection code:
- Get cwd
- Find workspace
- Parse target argument
- Determine rig from address or role

## Implementation
Extract helper function:
```go
type AgentContext struct {
    TownRoot string
    RigName  string
    Role     string
    Target   string  // polecat name or crew name
}

func getTargetAgentContext(args []string) (*AgentContext, error) {
    cwd, err := os.Getwd()
    if err != nil {
        return nil, fmt.Errorf("getting current directory: %w", err)
    }
    townRoot, err := workspace.FindFromCwd()
    if err != nil {
        return nil, fmt.Errorf("finding workspace: %w", err)
    }
    if townRoot == "" {
        return nil, fmt.Errorf("not in a Gas Town workspace")
    }
    // ... rest of target detection logic ...
}
```

## Acceptance criteria
- [ ] AgentContext struct defined
- [ ] getTargetAgentContext function extracts shared logic
- [ ] runMoleculeBurn uses getTargetAgentContext
- [ ] runMoleculeSquash uses getTargetAgentContext
- [ ] Duplicate code eliminated (diff shows net negative lines)
- [ ] go build ./... passes
- [ ] go test ./internal/cmd/... passes

Work reconciliation module

Port reconcile.py work verification to Go.

## Purpose

Verify assigned issues are completed before landing.

## Interface

```go
type ReconcileResult struct {
    CompletedIssues  []IssueInfo
    IncompleteIssues []IssueInfo
    AllComplete      bool
    PolecatsChecked  []string
    Errors           []string
}

func ReconcileWork(rig string, polecats []string) *ReconcileResult
func GetAssignedIssues(assignee string) []IssueInfo
func UnassignIssue(issueID string, resetStatus bool) error
```

## Logic

1. Get list of polecats in swarm
2. For each polecat, query beads for assigned issues
3. Categorize as completed (closed) or incomplete (open/in_progress)
4. Return summary for landing decision

## Handling Incomplete Work

If issues incomplete:
- Abort landing (default)
- Or force landing (leaves work unfinished)
- Unassign incomplete issues for future work

## Reference

PGT: swarm/reconcile.py

Patrol 7: Interrupted, routine


Polecat spawn: CLAUDE.md template lookup path is wrong

Template lookup uses rig.Path/templates/ but templates are in mayor/rig/templates/

In internal/polecat/manager.go installCLAUDETemplate():
  templatePath := filepath.Join(m.rig.Path, "templates", "polecat-CLAUDE.md")
  // Looks for: /Users/stevey/gt/gastown/templates/polecat-CLAUDE.md
  // But templates are at: /Users/stevey/gt/gastown/mayor/rig/templates/

This causes silent failure (template not found is OK) and polecats inherit the wrong CLAUDE.md from the git worktree.

Fix options:
1. Copy templates to rig root during rig init
2. Change lookup to use mayor/rig/templates/
3. Embed templates in binary


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


gt sling: Make target path parsing more forgiving

Current parsing rejects valid-looking paths like 'gastown/nux' or 'gastown/polecats/nux'.

Should accept:
- gastown/nux (polecat)
- gastown/Nux (polecat, case-insensitive)
- gastown/polecats/nux (explicit)
- gastown/crew/max (crew)
- gastown (auto-spawn)

The help says 'gastown/Toast' works but it doesn't. Parser is too strict.

Patrol #18: Stable


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
