Polecat cleanup should refuse to lose uncommitted work

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

## Current Problem

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

## Desired Behavior

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

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

## Implementation

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

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

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

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

    return nil
}
```

## Affected Commands

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


Improve test coverage in low-coverage packages

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

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


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


health-scan

Ping Witnesses and Refineries. Run gt status --health. Remediate if down.


Witness session cycling and handoff

Add session cycling and handoff protocol to Witness CLAUDE.md template.

## Session Cycling Protocol

```markdown
## Session Cycling

Your context will fill over long swarms. Proactively cycle when:
- Running for many hours
- Losing track of which workers you've checked
- Responses getting slower
- About to start complex operation

### Handoff Protocol

1. **Capture current state**:
```bash
town list .           # Worker states
town all beads        # Pending verifications
town inbox            # Unprocessed messages
```

2. **Compose handoff note**:
```
[HANDOFF_TYPE]: witness_cycle
[TIMESTAMP]: <now>
[RIG]: <rig>

## Active Workers
<list workers and status>

## Pending Verifications
<workers signaled done but not verified>

## Recent Actions
<last 3-5 actions>

## Warnings/Notes
<anything next session should know>

## Next Steps
<what should happen next>
```

3. **Send handoff**:
```bash
town mail send <rig>/witness -s "Session Handoff" -m "<note>"
```

4. **Exit cleanly**: End session, daemon spawns fresh one.

### On Fresh Session Start

1. Check for handoff: `town inbox | grep "Session Handoff"`
2. If found, read it and resume from handoff state
3. If not found, do full status check
```

## Implementation

Add to WITNESS_CLAUDE.md template.


Merge: gt-3x0z.1

branch: polecat/furiosa
target: main
source_issue: gt-3x0z.1

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.


request-shutdown

Send shutdown request to Witness.
Wait for termination.

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

Swarm cleanup: delete merged polecat branches and reset state

After a swarm completes and branches are merged, leftover state remains:

## Current Problem

1. **Remote branches not deleted** - polecat/* branches stay on origin after merge
2. **Polecat clones not reset** - still on old branch with completed work
3. **No cleanup command** - manual cleanup required

## Observed After Swarm

Remote branches still present:
- origin/polecat/Morsov
- origin/polecat/Nux
- origin/polecat/Rictus
- origin/polecat/Slit
- origin/polecat/Toast

## Proposed Solution

Add cleanup commands:

1. gt swarm cleanup <swarm-id> - Clean up after swarm completion
   - Delete remote polecat branches that were merged
   - Reset polecat clones to main
   - Clear issue assignments

2. gt polecat reset <rig>/<polecat> - Reset single polecat
   - git checkout main && git pull
   - Delete local polecat branch
   - Clear current issue assignment

3. Auto-cleanup option on gt session stop --cleanup

## Manual Cleanup For Now

git push origin --delete polecat/Nux polecat/Toast ...
cd polecats/Nux && git checkout main && git pull


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

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


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

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.


gt polecat: add 'done' or 'finish' command to transition from working to idle

When a polecat finishes work but session wasn't properly cleaned up, there's no way to reset it from 'working' state back to 'idle'.

Tried:
```
gt polecat sleep gastown/Angharad
Error: sleeping polecat: polecat is not active (state: working)
```

The sleep command only works on 'active' polecats, not 'working' ones.

Had to manually edit state.json to reset:
```
jq '.state = "idle" | .issue = ""' state.json
```

Need a command like:
```
gt polecat done gastown/Angharad   # working -> idle
gt polecat finish gastown/Angharad # working -> idle
gt polecat reset gastown/Angharad  # any state -> idle (force)
```


test message


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

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


Mail coordination should use town-level database

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


Session management: start, stop, attach, capture

Polecat session lifecycle management.

## Interface

```go
type SessionManager struct {
    tmux *Tmux
    rig  *Rig
}

func NewSessionManager(tmux *Tmux, rig *Rig) *SessionManager

// Lifecycle
func (sm *SessionManager) Start(polecat string, opts StartOptions) error
func (sm *SessionManager) Stop(polecat string) error
func (sm *SessionManager) IsRunning(polecat string) (bool, error)
func (sm *SessionManager) List() ([]SessionInfo, error)

// Interaction
func (sm *SessionManager) Attach(polecat string) error
func (sm *SessionManager) Capture(polecat string, lines int) (string, error)
func (sm *SessionManager) Inject(polecat string, message string) error

type StartOptions struct {
    WorkDir   string   // defaults to polecat clone dir
    Issue     string   // optional: issue to work on
    Command   string   // optional: override claude command
}

type SessionInfo struct {
    Polecat   string
    SessionID string
    Running   bool
    StartedAt time.Time
}
```

## Session Naming

`gt-<rig>-<polecat>` (e.g., `gt-wyvern-Toast`)

## Start Flow

1. Verify polecat clone exists
2. Check no existing session
3. Create tmux session in polecat workdir
4. Send initial command: `claude` or custom
5. If issue provided, inject initial prompt

## Stop Flow

1. Capture final output (for logging)
2. Send exit/quit command
3. Wait briefly for graceful shutdown
4. Kill session if still running

## Capture

Uses tmux capture-pane to get recent output. Returns last N lines.

## Inject

Sends text to session via tmux send-keys. Used for:
- Mail notifications
- Witness nudges
- User messages


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


Phase 4.1: mol-deacon-patrol uses ephemeral

Deacon patrol cycles run as ephemeral molecules.

## Current Deacon Loop

```
while running:
    check_heartbeat()
    check_mail()
    sleep(interval)
```

## Molecule-Based Loop

```
while running:
    mol = bd mol bond mol-deacon-patrol-cycle --ephemeral
    execute_cycle(mol):
        check_heartbeat()
        check_mail()
        log_status()
    summary = generate_cycle_summary()
    bd squash mol --summary summary
    sleep(interval)
```

## Benefits

- Each cycle is tracked
- Digests show daemon health over time
- Can query: 'show me patrol cycles from last hour'
- Crash mid-cycle → ephemeral shows where we were


Design: Mayor session cycling and handoff

Design for Mayor session cycling and structured handoff.

## Overview

Mayor coordinates across all rigs and runs for extended periods. Needs session cycling pattern with structured handoff notes.

## Key Elements

1. Session cycling recognition (when to cycle)
2. Handoff note format (structured state capture)
3. Handoff delivery (mail to self)
4. Fresh session startup (reading and resuming)

## Subtasks (implementation)

- gt-g2d: Mayor session cycling prompting
- gt-sye: Mayor startup protocol prompting
- gt-vci: Mayor handoff mail template
- gt-1le: town handoff command (optional, P2)

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


Adaptive backoff for daemon heartbeat

Track agent responsiveness and adjust heartbeat frequency.

## Per-Agent State

```go
type AgentBackoff struct {
    BaseInterval    time.Duration  // 60s default
    CurrentInterval time.Duration  // grows when busy
    MaxInterval     time.Duration  // 10min cap
    ConsecutiveMiss int            // pokes with no response
}
```

## Strategy Options

- **Fixed**: Always 60s (current, simple)
- **Geometric**: 60s → 90s → 135s → 202s (factor 1.5)
- **Exponential**: 60s → 120s → 240s (factor 2, aggressive)

## Recovery

When agent responds (runs a command):
- Reset ConsecutiveMiss to 0
- Return to BaseInterval immediately

## Benefits

- Reduces noise for busy agents
- Saves resources during quiet periods
- Still catches stuck agents (max interval cap)


Implement shared beads architecture for rig

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

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

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

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

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


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.


Work on ga-lue: Implement Witness as Claude agent. Conver...

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


Interrupt vs Queue mail semantics

Add priority/delivery semantics to mail messages.

## Semantics

| Type | Delivery | Use Case |
|------|----------|----------|
| Interrupt | tmux send-keys | Lifecycle, URGENT, stuck detection |
| Queue | Create message only | Normal mail, status, heartbeat |

## Implementation

- `bd mail send --interrupt` uses tmux send-keys notification
- Default is queue (agent checks with `gt mail check`)
- Urgent flag on messages for interrupt delivery

## Agent Side

- `gt mail check --quiet` - non-blocking check for queued mail
- `gt mail wait` - block until mail arrives (for idle agents)
- Heartbeats become queued, agent checks at natural breakpoints


Cross-project dependency workflow (Gas Town side)

Gas Town integration for cross-project dependencies.

## Components
- gt-zniu: gt park command (park molecule on external dep)
- gt-in3x: gt spawn --continue (resume parked molecule)
- gt-5uf3: Patrol auto-resume (future)

## Design Doc
See: docs/cross-project-deps.md

## Depends on Beads
- bd-h807: Cross-project dependency support (epic)

## Launch Plan
Phase 1 (launch): gt park + gt spawn --continue (manual resume)
Phase 2 (later): Patrol auto-resume


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


Phase 5.2: Ephemeral error handling and recovery

Handle edge cases in ephemeral molecule lifecycle.

## Scenarios

### Agent dies mid-molecule
- Ephemeral state persists
- Witness detects stall (no heartbeat)
- Options:
  a. Nudge agent to resume
  b. Reassign to new agent
  c. Escalate to Mayor

### Squash fails
- Retry with exponential backoff
- If persistent failure, escalate
- Don't lose the ephemeral state until squash succeeds

### Orphaned molecules
- Molecule started, never completed
- gt doctor detects (>24h old with no activity)
- Options:
  a. Manual review
  b. Auto-abandon with 'abandoned' digest
  c. Reassign

### Ephemeral repo corruption
- Re-init from scratch
- Active molecules are lost
- Main beads is source of truth for assigned work

## Implementation

Add error handling to:
- bd mol bond (handle init failures)
- bd squash (retry logic)
- gt doctor (recovery suggestions)


Town-level beads: Real DB for coordination mail

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

## Background

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

## Design

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

Matches HOP hierarchy: platform > project > worker

## Structure

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

## Tasks

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

## Addressing

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


Polecats must not create GitHub PRs

Polecats should never use 'gh pr create' or create GitHub pull requests.

## Correct Workflow
1. Polecat works on polecat/<name> branch
2. Commits and pushes to origin
3. Creates beads MR issue (type: merge-request)
4. Refinery processes the MR and merges to main

## Wrong Workflow
- Using gh pr create
- Creating GitHub pull requests directly

## Why
- Refinery is our merge queue processor
- GitHub PRs bypass our workflow
- Beads MRs are the coordination mechanism


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


self-review

Review your own changes. Look for:
- Bugs and edge cases
- Style issues
- Missing error handling
- Security concerns

Fix any issues found before proceeding.

Swarm state persistence: manifest + state + events

Upgrade swarm persistence to match PGT pattern.

## Current State
Single .gastown/swarms.json with all swarms.

## Target State (per-swarm)
```
.gastown/swarms/
└── <swarm-id>/
    ├── manifest.json  # Immutable config
    ├── state.json     # Mutable progress
    ├── events.jsonl   # Audit log
    └── report.md      # Generated report
```

## File Schemas

### manifest.json (immutable after creation)
```json
{
  "id": "sw-1",
  "title": "Epic description",

}
```

### events.jsonl (append-only audit)
```jsonl
{"event": "created", "ts": "...", "data": {...}}
{"event": "task_assigned", "ts": "...", "data": {...}}
{"event": "task_merged", "ts": "...", "data": {...}}
```

## Benefits
- Audit trail via events.jsonl
- Manifest immutability prevents corruption
- Cleaner separation of concerns
- Per-swarm isolation

## Migration
Keep backward compat with swarms.json during transition.

## Files to Modify
- internal/swarm/manager.go: Refactor persistence
- internal/cmd/swarm.go: SwarmStore → directory-based

## Acceptance Criteria
- [ ] Per-swarm directory structure
- [ ] Events logged to JSONL
- [ ] Manifest immutable after creation
- [ ] List command aggregates from directories


Automatic spawn for ready work

Auto-spawn polecats for ready work:

When Witness has capacity (active_workers < max_workers):
1. Query bd ready for unblocked issues
2. Filter to rig-appropriate work (by prefix or epic)
3. For each ready issue up to capacity:
   - gt spawn --issue <id>
   - Track that we spawned for this issue

Configuration (in rig config.json):
- max_workers: 4 (default)
- spawn_delay: 5s between spawns
- auto_spawn: true/false

This enables 'fire and forget' swarming:
- Mayor creates epic with children
- Mayor tells Witness to work epic
- Witness spawns polecats automatically
- Witness cleans up as they complete

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`.


Beads CLI wrapper: shell out to bd

Wrapper for bd (beads CLI) commands.

## Interface

```go
type Beads struct {
    workDir string
}

func NewBeads(workDir string) *Beads

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

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

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

## Data Types

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

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

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

## Implementation

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

## Error Handling

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


Plugin system: subprocess JSON protocol

Language-agnostic plugin system via subprocess JSON protocol.

## Concept

Allow extending Gas Town with external scripts/programs. Plugins communicate via stdin/stdout JSON.

## Protocol

Request (gt → plugin):
```json
{"method": "check", "params": {"rig": "wyvern", "polecat": "Toast"}}
```

Response (plugin → gt):
```json
{"result": {...}, "error": null}
```

Error response:
```json
{"result": null, "error": {"code": 1, "message": "..."}}
```

## Interface

```go
type Plugin struct {
    Name    string
    Path    string  // executable path
    Methods []string
}

type PluginManager struct {
    plugins map[string]*Plugin
}

func NewPluginManager() *PluginManager
func (pm *PluginManager) Register(plugin *Plugin) error
func (pm *PluginManager) Call(plugin, method string, params any) (any, error)
func (pm *PluginManager) Discover(dir string) error  // auto-discover plugins
```

## Plugin Discovery

Look in:
1. `<town>/plugins/`
2. `~/.config/gastown/plugins/`
3. System path with `gt-plugin-*` prefix

## Built-in Hooks

Plugins can register for events:
- `polecat.started` - Polecat session started
- `polecat.done` - Polecat signals done
- `merge.requested` - MR submitted
- `merge.completed` - MR merged

## Use Cases

- Custom health checks
- Integration with external systems (Slack, etc.)
- Custom merge policies
- Metrics collection

## Future

Consider MCP integration for richer plugin capabilities.


Fix role detection for nested rig structures

When gastown/ has its own mayor/ dir, workspace detection finds it as town root instead of ~/ai. This breaks polecat/refinery/witness detection when running from within a rig.


Agent monitoring and status inference

Agent monitoring with status inference from activity, like PGT.

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

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

## Activity Detection

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

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

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

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

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

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

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


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.

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)

Reference: docs/merge-queue-design.md#observability


MR: gt-test (main)

branch: main
target: main
source_issue: gt-test


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


Rollback support: gt mq revert for problematic merges

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

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

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

Track revert in MR metadata for audit trail.

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


Document merge queue architecture

Update docs/architecture.md with:

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

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


Molecule schema: YAML format for workflow definitions

Define the YAML schema for molecule definitions:

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

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

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


Phase 4.2: Witness/Refinery patrol molecules

Extend ephemeral patrol pattern to Witness and Refinery.

## Witness Patrol Cycle

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

## Refinery Patrol Cycle

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

## Quiescent Mode

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


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

Witness role template + CLAUDE.md

Create the Witness agent's role context:

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

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

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


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


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.


Test infrastructure: fixtures, mocks, integration tests

Test infrastructure for Gas Town.

## Test Categories

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

### Integration Tests

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

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

## Test Helpers

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

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

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

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

## CI Integration

- Coverage report generation

## Test Data

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


Polecat beads not synced with rig beads

When gt spawn assigns an issue to a polecat, the polecat cannot find the issue because:

1. Rig beads at /gt/gastown/.beads contains gt-th7
2. Polecat beads at /gt/gastown/polecats/dementus/.beads does NOT have gt-th7
3. bd sync in polecat dir pulls from beads-sync branch which doesn't have the new issue
4. Rig bd sync uses 'main' branch, causing a branch mismatch

The polecat gets a work assignment for an issue it literally cannot see.

## Root Cause

- Rig beads and polecat beads are separate git-tracked copies
- No mechanism to propagate newly created issues from rig to polecats before assignment
- Sync branch configuration mismatch between rig and polecats

## Fix Options

1. gt spawn should sync rig beads before assigning work
2. gt spawn should sync polecat beads after assignment
3. Use shared beads (symlink or same DB) instead of copies
4. Push new issues immediately on create

Note: This sync mismatch is resolved by gt-9nf (fresh polecats). Rather than fixing sync between stale clones, we'll always create fresh worktrees. This issue documents the root cause for posterity.


rebase-main

Rebase against main to incorporate any changes.
Resolve conflicts if needed.

git fetch origin main
git rebase origin/main

If there are conflicts, resolve them carefully and continue the rebase.

Depends: self-review, verify-tests


GGT Command Parity: Complete gt command coverage

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

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


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.


CLI: worker status reporting commands

Worker status reporting CLI for polecats to report progress.

## Commands

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

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

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

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

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

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

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

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

## New File
internal/cmd/worker.go

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

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


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.


Phase 2.2: gt prime shows ephemeral molecule context

Update gt prime to detect and display ephemeral molecule state.

## Detection

1. Check for active ephemeral molecule assigned to current identity
2. Parse molecule progress (current step, total steps)
3. Show in prime output

## Output

```
🔧 Polecat furiosa, checking in.

📦 Molecule: mol-polecat-work (eph-abc123)
   Step 3/8: do-work
   Source: gt-rixa
   Started: 10 minutes ago

Run 'bd mol status' for full molecule state.
```


Merge polecat/slit: docs bd mol bond/squash/burn CLI

Branch: polecat/slit

## Summary
Added comprehensive CLI reference documentation for the three molecule lifecycle commands to molecules.md:

- **bd mol bond**: Instantiate proto into Mol (durable) or Wisp (ephemeral)
- **bd mol squash**: Complete molecule and generate digest
- **bd mol burn**: Abandon molecule without digest

Includes argument tables, behavior descriptions, examples, and a lifecycle diagram showing the steam engine metaphor mapping.

Closes: gt-odvf


Document the Propulsion Principle

Write canonical documentation for the Universal Gas Town Propulsion Principle.

Location: gastown/mayor/rig/docs/propulsion-principle.md

Content:
- The One Rule (hook has work → work happens)
- Why it works (stateless agents, molecule-driven)
- The sling lifecycle diagram
- Agent startup protocol
- Examples and anti-patterns

This is foundational theory-of-operation documentation.


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.


gt mail read: Support numeric indices for message ID

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

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

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


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.


Plugin surface for daemon lifecycle hooks

Allow rigs to customize daemon behavior via hooks/plugins.

## Hook Points

- on_heartbeat: Called during daemon heartbeat cycle
- on_worker_idle: Called when worker goes idle
- on_worker_stuck: Called when stuck detection triggers
- on_lifecycle_request: Called before processing lifecycle

## Configuration

```
<rig>/config/daemon-hooks.json
{
  "on_heartbeat": "./hooks/check-ci-status.sh",
  "on_worker_idle": "./hooks/maybe-assign-work.sh",
  "idle_threshold": "5m",
  "custom_signals": [
    {"name": "ci_status", "command": "./hooks/get-ci.sh"}
  ]
}
```

## Signal Contribution

Hooks can return signals that feed into decision engine:
- SKIP_POKE: Don't poke this agent
- FORCE_POKE: Override backoff, poke now
- CUSTOM_DATA: Extra context for logging

## Use Cases

- Check CI status before interrupting test runs
- Auto-assign work when worker becomes idle
- Custom stuck detection for specific workflows


gt uninstall: Clean removal of Gas Town harness

Add 'gt uninstall' command to cleanly remove a Gas Town installation.

Should:
- Remove harness directory structure
- Optionally preserve rigs/data with --keep-data flag
- Warn about running sessions
- Clean up any global config references


gt daemon: Background service management

## Summary

ONE daemon for all Gas Town - a simple Go process (not a Claude agent) that:
1. Pokes agents periodically (heartbeat)
2. Processes lifecycle requests
3. Restarts sessions when agents request cycling

## Architecture

Daemon (gt daemon)
- Pokes Mayor: "HEARTBEAT: check your rigs"
- Pokes each Witness: "HEARTBEAT: check your workers"
- Has inbox at daemon/ for lifecycle requests
- Restarts sessions on cycle requests

## NOT the daemon's job:
- Making decisions (Witnesses do that)
- Running Claude (it's a Go process)
- Processing work (polecats do that)
- Direct polecat management (Witnesses do that)

The daemon is a **dumb scheduler** - poke things, execute lifecycle requests. All intelligence is in agents.

## Commands

- gt daemon start: Start daemon (background)
- gt daemon stop: Stop daemon
- gt daemon status: Show daemon status
- gt daemon logs: View daemon logs

## Daemon Loop

Every heartbeat interval:
1. Poke Mayor
2. For each rig: Poke Witness
3. Process lifecycle requests from daemon/ inbox
4. Check for dead sessions, restart if cycle requested

## Lifecycle Request Handling

Daemon checks its inbox (daemon/) for lifecycle requests:
- From Mayor: cycle/restart Mayor session
- From Witnesses: cycle/restart Witness session

On request:
1. Verify agent state shows requesting_cycle
2. Kill session
3. Start new session
4. Clear requesting_cycle flag

## Poke Protocol

Poke = tmux inject "HEARTBEAT: do your job"
- Agent ignores if already working
- Agent wakes up if idle
- Idempotent - multiple pokes are fine

## Lifecycle Hierarchy

- Daemon manages: Mayor, all Witnesses
- Witness manages: Polecats, Refinery (per rig)
- Crew: self-managed (human workspace)

## Related Issues

- gt-kmn.11: Daemon heartbeat details
- gt-gby: gt handoff command (unified lifecycle)
- gt-u1j.9: Fold witness daemon into this


gt crew at/attach: Start session in crew workspace

Implement 'gt crew at <rig>/<name>' and 'gt crew attach <name>' commands:
- Start tmux session (optional - could just print cd instructions)
- Launch claude code in the workspace
- Deliver any pending mail
- Support --no-tmux to just print directory path
- 'attach' infers rig from cwd


Implement gt mol status command

Show what's on an agent's hook.

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

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

If no target, shows current agent's status.

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

func (c *LocalConnection) ReadFile(path string) ([]byte, error) {
    return os.ReadFile(path)
}
// etc.
```

## Command Execution

Uses exec.Command:
```go
func (c *LocalConnection) Exec(cmd string, args ...string) ([]byte, error) {
    return exec.Command(cmd, args...).Output()
}
```

## Tmux

Delegates to Tmux wrapper:
```go
func (c *LocalConnection) TmuxNewSession(name, dir string) error {
    return c.tmux.NewSession(name, dir)
}
```

## Notes

Straightforward implementation - this is the "baseline" connection that SSHConnection will mirror remotely.


Work on gt-e11: gt mail send priority flag is incompatibl...

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


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


gt mq submit: creates task type instead of merge-request type

## Problem

`gt mq submit` creates an issue with `type: task` but should be `type: merge-request`.

## Evidence

```
$ bd show gt-n508
gt-n508: Merge: gt-70b3
Status: open
Priority: P1
Type: task      <-- WRONG, should be merge-request
...
Description:
type: merge-request   <-- Correct type is in description, not in actual type field
```

## Impact

`gt mq list` shows empty queue because it queries for `type: merge-request`

## Fix

`gt mq submit` should set `--type merge-request` when creating the bead.


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

gt mq list: show queue with status/priority/age

Implement 'gt mq list' command to display the merge queue.

Output format:
ID          STATUS       PRIORITY  BRANCH                    WORKER  AGE
gt-mr-001   ready        P0        polecat/Nux/gt-xyz        Nux     5m
gt-mr-002   in_progress  P1        polecat/Toast/gt-abc      Toast   12m
gt-mr-003   blocked      P1        polecat/Capable/gt-def    Capable 8m
            (waiting on gt-mr-001)

Options:
- --ready: show only ready-to-merge (no blockers, not in progress)
- --status STATUS: filter by status
- --worker WORKER: filter by worker
- --epic EPIC: show MRs targeting integration/EPIC

Under the hood: bd list --type=merge-request with filters.

Reference: docs/merge-queue-design.md#gt-mq-list


Per-rig beads repo configuration

Add per-rig beads configuration to rig config schema.

## Config Schema

In each rig's config.json:

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

## Repo Options

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

## Environment Injection

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

## Resolution Logic

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

## Backwards Compatibility

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


Engineer session restart protocol

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

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

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


bd ready --blockers: prioritize issues that block other work

bd ready should prioritize issues that are blocking other work.

**From VC**: Blocker-first prioritization in GetReadyWork(). ~100 lines.
Algorithm: baseline-failure first, then discovered:blocker, then by priority.

**Gas Town implementation**: CLI flag or default behavior:
```bash
bd ready --blockers-first  # Or make this default
```

Checks dependency graph. Issues with many dependents surface first.

**Value**: Unblocks parallelism faster. Critical path gets cleared.

**VC lesson**: Without blocker priority, work can starve on discovered issues.


Test Task 1: Add comment to gt.go


Test message

Testing GGT mail via beads


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


gt session restart/status: Complete session management

Add missing session subcommands:

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

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


CLI: rig commands (list, show, add)

Rig management CLI commands.

## Commands

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

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

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

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

## Implementation

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


Add human escalation configuration

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


Merge polecat/rictus: Add molecule phase lifecycle diagram

Branch: polecat/rictus

Adds molecule phase lifecycle diagram to architecture.md showing Proto → Mol/Wisp → Digest state transitions with the 'states of matter' metaphor. Also documents when to use Mol (durable) vs Wisp (ephemeral).

Closes: gt-c6zs


HTTP work server: gt worker serve command

## Overview

HTTP server that runs inside Cloud Run containers, accepting work requests.

## Command

```bash
gt worker serve --port 8080
```

## Implementation

```go
type WorkServer struct {
    port    int
    handler *WorkHandler
}

func (s *WorkServer) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    switch r.URL.Path {
    case "/work":
        s.handleWork(w, r)
    case "/health":
        s.handleHealth(w, r)
    default:
        http.NotFound(w, r)
    }
}

func (s *WorkServer) handleWork(w http.ResponseWriter, r *http.Request) {
    // 1. Parse WorkRequest
    // 2. Clone/pull repo
    // 3. Start Claude on issue
    // 4. Stream WorkEvents as NDJSON
    // 5. Return WorkResult
}
```

## Streaming Response

```go
func (s *WorkServer) streamEvents(w http.ResponseWriter, events <-chan WorkEvent) {
    flusher, _ := w.(http.Flusher)
    encoder := json.NewEncoder(w)
    for event := range events {
        encoder.Encode(event)
        flusher.Flush()
    }
}

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


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


🤝 HANDOFF: Investigate beads-sync divergence (221 files)

## Context

gt doctor now detects orphaned code on beads-sync branch. Running it shows:

  beads-sync-orphans: 221 file(s) on beads-sync not in main

This is in the gastown repo (checking from crew/max).

## Background

- Earlier today we recovered orphaned mail migration code lost in merge 96c773f
- Recently simplified architecture: all workers use mayor/rig/.beads (redirects)
- This simplification may have caused beads-sync branch to diverge unexpectedly

## Investigation Steps

1. From crew/max run: git diff main..beads-sync --stat
2. Check if beads-sync should even exist anymore (was for multi-clone sync)
3. If obsolete with redirect architecture, consider deleting it
4. If it has legitimate changes, cherry-pick or merge to main

## Key Question

With all workers using mayor/rig/.beads via redirects, is beads-sync still needed?

## Commands

git log main..beads-sync --oneline | head -20
git diff main..beads-sync -- *.go | head -100


Crew workers getting wrong CLAUDE.md (shows Refinery)

## Problem

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

## Evidence

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

## Expected

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

## Impact

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

## Fix

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

Witness Plugin System

Plugin infrastructure for witness patrol customization.

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

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

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

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

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


Implement gt mq CLI commands

Add gt mq subcommands as sugar over bd:

- gt mq submit: Create MR for current branch
- gt mq list: Show open merge requests
- gt mq next: Show next MR ready to process
- gt mq process: Engineer processes the queue
- gt mq reorder <id> --after <x>: Change ordering via deps
- gt mq status <id>: Show MR details

All commands should work with the Beads data plane.


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.


Merge execution: merge, test, push

Implement the actual merge execution.

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

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

Handle push failures with retry logic.

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


Fix TestHasPolecat test failure in internal/session

TestHasPolecat in internal/session/manager_test.go fails because it expects
specific polecats (Toast, Cheedo) to exist in the test environment.

Error:
```
manager_test.go:46: expected hasPolecat(Toast) = true
manager_test.go:49: expected hasPolecat(Cheedo) = true
```

Fix: Either create test fixtures or mock the filesystem check.


Fetch and conflict check: git operations for MR

Implement git operations for MR processing.

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

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

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


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

Deacon Kernel: event processing molecule architecture

Extend the Deacon from "health orchestrator" to "event processing kernel" that runs a
molecule (rounds) each wake cycle, like an OS kernel scheduler.

## Core Insight

The Deacon already has:
- Wake cycle (daemon poke, timer, lifecycle request)
- Mail as event queue
- Health scanning
- Lifecycle processing

But it is REACTIVE. This epic makes it PROACTIVE with a structured molecule:

```
Deacon Wake
├── Step 0: Session Check (should I cycle myself?)
├── Step 1: Health Scan (Mayor, Witnesses, Crew, Refineries)
├── Step 2: Lifecycle Processing (cycle/restart/shutdown requests)
├── Step 3: Plugin Execution (scheduled, event-triggered, human-requested)
├── Step 4: Event Callbacks (timers, subscriptions)
└── Step 5: Heartbeat + Wait
```

## Key Design Decisions

1. **Session cycling first** - Token costs are quadratic with session length.
   Deacon should aggressively cycle to fresh sessions. First step of every
   wake is "do I need a new session?" based on context budget.

2. **Pinned bead with marching orders** - A pinned bead (like gt prime for
   agents) defines the Deacon's rounds molecule. This is the Deacon's
   "kernel" - its operating loop.

3. **Keepalive file for daemon quieting** - Instead of daemon tmux-poking
   the Deacon (which interrupts work), Deacon writes a keepalive file.
   Daemon reads it and backs off. Worst case: Deacon forgets, gets one
   extra heartbeat it squelches.

4. **Molecule-based rounds** - The wake cycle becomes a molecule with steps.
   Each step can have plugins (inline attention). Steps can be added/modified
   by updating the pinned bead.

## Architecture

```
Go Daemon (minimal, dumb)
├── Reads {townRoot}/deacon/keepalive.json
├── If fresh: do nothing
├── If stale: poke Deacon (fallback)
└── Process lifecycle requests (still daemon's job)

Deacon (Claude agent, smart)
├── Wakes: poke, timer, mail event
├── Writes keepalive (quiets daemon for duration of rounds)
├── Runs rounds molecule:
│   ├── session-check: cycle if context budget low
│   ├── health-scan: check agents, remediate
│   ├── lifecycle: process requests
│   ├── plugins: run scheduled/triggered plugins
│   ├── events: process timer/event callbacks
│   └── complete: update heartbeat, wait
└── Reads marching orders from pinned bead
```

## Relation to Existing Work

- Extends gt-5af (Deacon infrastructure) - CLOSED
- Relates to gt-axz (Plugin architecture) - P3
- Fits into phase3-deacon of gt-ngpz (Christmas Plan)
- Enables gt-976 (Crew lifecycle) as part of health-scan step


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

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

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

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


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

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

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


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.


Rig doctor checks: Refinery health, clones, gitignore

Rig-level doctor checks.

## Checks

### RigIsGitRepo
- Verify .git/ directory exists
- Verify git status works
- Fix: Cannot auto-fix

### GitExcludeConfigured
- Check .git/info/exclude contains Gas Town dirs
- Required entries: polecats/ witness/ refinery/ mayor/
- Fix: Append missing entries

### WitnessExists
- Verify witness/ directory exists
- Verify witness/rig/ is a git clone
- Verify witness/mail/inbox.jsonl exists
- Fix: Create structure, clone repo

### RefineryExists
- Verify refinery/ directory exists
- Verify refinery/rig/ is a git clone
- Verify refinery/mail/inbox.jsonl exists
- Fix: Create structure, clone repo

### MayorCloneExists
- Verify mayor/ directory exists
- Verify mayor/rig/ is a git clone
- Fix: Create structure, clone repo

### PolecatClonesValid
- For each polecat in polecats/:
  - Verify is a git clone
  - Verify on polecat branch
  - Warn if has uncommitted changes
- Fix: Cannot auto-fix (data loss risk)

### BeadsConfigValid (if applicable)
- If .beads/ exists, verify bd commands work
- Check beads sync status
- Warn if out of sync
- Fix: Run bd sync

## Implementation

```go
var RigChecks = []Check{
    &RigIsGitRepoCheck{},
    &GitExcludeConfiguredCheck{},
    &WitnessExistsCheck{},
    &RefineryExistsCheck{},
    &MayorCloneExistsCheck{},
    &PolecatClonesValidCheck{},
    &BeadsConfigValidCheck{},
}
```


Merge: gt-rana.3

branch: polecat/dementus
target: main
source_issue: gt-rana.3
rig: gastown


Design: Work flow simulation and validation

Validate GGT designs through simulation before implementation.

## Validation Approaches

### 1. Dry-Run Simulation (Recommended First)
Mayor walks through scenarios mentally/on paper:
- "If polecat Toast signals done with dirty git state, what happens?"
- "If Witness context fills mid-verification, what state is lost?"
- "If two polecats try to close same issue, what happens?"

Create beads for any gaps discovered.

### 2. Real Work in gastown-py
Use Python Gas Town to stress-test assumptions:
- Run actual batch work on test repos
- Observe edge cases in practice
- Document issues found

### 3. Edge Case Analysis
Systematic review of failure modes:
- Agent crashes mid-operation
- Network failures during sync
- Concurrent access to shared state
- Context limits hit at bad times

## Key Scenarios to Validate

- [ ] Witness session cycling (state preservation)
- [ ] Polecat decommission with dirty state
- [ ] Merge conflicts in queue
- [ ] Beads sync conflicts between workers
- [ ] Escalation path (stuck worker -> Mayor)
- [ ] Cross-rig communication
- [ ] Federation mail routing (future)

## Success Criteria

- No data loss scenarios identified
- Clear recovery paths for all failure modes
- Edge cases either handled or documented as limitations
- Design improves as model cognition improves

## Output

For each scenario validated:
1. Document in relevant bead if issue found
2. Create new beads for missing functionality
3. Update architecture.md if design changes

Auto-rebase on conflict: optional automatic rebase

Implement automatic rebase as conflict resolution option.

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

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

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

Add agent abstraction layer to support non-Claude agents

Currently Gas Town hardcodes 'claude --dangerously-skip-permissions' throughout the codebase for spawning agents. We should add an abstraction layer to support other AI agents (e.g., Gemini CLI, OpenAI agents, local models).

Locations that spawn Claude:
- internal/cmd/mayor.go:131
- internal/cmd/deacon.go:150
- internal/cmd/witness.go:280
- internal/cmd/crew.go (multiple locations)
- internal/cmd/up.go:190, 229
- internal/session/manager.go:146
- internal/refinery/manager.go:207

Suggested approach:
1. Create an agent package with an interface
2. Add configuration for agent type in town/rig config
3. Replace hardcoded claude commands with agent.Spawn() calls
4. Support agents: claude, gemini, openai, local (ollama, etc.)


request-shutdown

Send shutdown request to Witness.
Wait for termination.

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

CLI: spawn command

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

## Command

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

## What It Does

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

## Options

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

## Auto-Select Logic

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

## Initial Context

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

<description>

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

## Implementation

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

gt crew remove: Remove crew workspace

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


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.


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.


Polecat prompting: gt mq submit on completion

Update Polecat CLAUDE.md prompting to:

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

The Polecat self-reports completion to the merge queue.

gt session capture: Support positional line count argument

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

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

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

Deacon keepalive: quiet daemon during rounds

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

## Problem

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

## Solution

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

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

## Files

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

## Deacon Behavior

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

## Daemon Changes

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

## Worst Case

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

## Configuration

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


Session pre-shutdown checks

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

## Pre-Shutdown Checks

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

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

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

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

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

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

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

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

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


gt 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)

Preflight molecule: verify baseline health before work

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

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

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

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

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

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

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.


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.


MR ID generation: prefix-mr-hash convention

Generate merge-request IDs following the convention: <prefix>-mr-<hash>

Example: gt-mr-abc123 for a gastown merge request.

This distinguishes MRs from regular issues while keeping them in the same namespace.
The hash should be derived from branch name + timestamp for uniqueness.

Implement: GenerateMRID(prefix, branch string) string
