Add gate checking to Deacon patrol loop

Integrate gate checking into Deacon's patrol cycle.

## Patrol Integration
```go
func (d *Deacon) checkGates(ctx context.Context) {
    gates, _ := d.store.ListOpenGates(ctx)

    for _, gate := range gates {
        // Check timeout
        if time.Since(gate.CreatedAt) > gate.Timeout {
            d.notifyWaiters(gate, "timeout")
            d.closeGate(gate, "timed out")
            continue
        }

        // Check condition
        if d.checkCondition(gate.AwaitType, gate.AwaitID) {
            d.notifyWaiters(gate, "cleared")
            d.closeGate(gate, "condition met")
        }

CLI: doctor diagnostics and auto-repair

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

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

Checks to Implement:

Molecule instantiation: create child beads from template

When instantiating a molecule on a work bead:

## Transaction Flow

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

## Parsing Conventions

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

## Parameterization

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

Context map provided at instantiation time.

## API

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

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

gt polecat add: should handle existing branch gracefully

## Problem

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

## Current Behavior

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

## Expected Behavior

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

## Context

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

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.


Beads as Universal Data Plane

## Vision

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

## New Bead Categories

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

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

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

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

## v1 Priority

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


Git safety audit module

Port git_audit.py safety checks to Go.

## Purpose

Before destroying polecat clones, verify no code is at risk.

## Checks

1. Uncommitted changes (staged and unstaged)
2. Unpushed commits
3. Git stashes
4. Local-only branches (not tracking remote)

## Beads-Only Classification

Some files are safe to discard:
- .beads/*
- .claude/settings.json

Changes only affecting these = "beads-only" = safe to destroy.

## Interface

```go
type GitAuditResult struct {
    Polecat              string
    Path                 string
    UncommittedFiles     []string
    UncommittedIsBeadsOnly bool
    UnpushedCommits      int
    Stashes              []StashInfo
    StashesAreBeadsOnly  bool
    LocalBranches        []string
    Error                error
}

func (r *GitAuditResult) HasCodeAtRisk() bool

func AuditPolecat(name string, path string) *GitAuditResult
func AuditPolecats(polecats []PolecatInfo) []*GitAuditResult

gt sling --force: return displaced work to ready pool

When slinging with --force to an agent with occupied hook, the displaced molecule should be returned to the ready pool rather than silently orphaned.

Current behavior:
- --force overwrites the hook attachment
- Previous work becomes orphaned (still assigned but not pinned)

Desired behavior:
1. Unpin the displaced molecule (clear assignee, set pinned=false)
2. Print warning in tool output: 'Warning: displaced gt-xxx back to ready pool'
3. Proceed with new sling

This ensures:
- No silent data loss
- Agent sees the warning and can act on it
- Human caller sees what happened
- Displaced work is discoverable via 'bd ready'

Implementation location: checkHookCollision() or the sling handlers themselves (after the --force check passes)

gt swarm is implemented but undocumented

internal/swarm/ package is fully implemented with:
- gt swarm create
- gt swarm status
- gt swarm list
- gt swarm land
- gt swarm cancel
- gt swarm start

But no documentation exists for it:
- Not in README
- Not in architecture.md (uses different terminology)
- Not in any role prompts

Either:
1. Document gt swarm as the canonical mechanism
2. Or deprecate it in favor of gt sling

Related to gt-6n13 (competing molecule mechanisms)


Swarm learning: Refinery merge queue automation

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


mol-witness-patrol

Per-rig worker monitor patrol loop.

The Witness is the Pit Boss for your rig. You watch polecats, nudge them toward
completion, verify clean git state before kills, and escalate stuck workers.

**You do NOT do implementation work.** Your job is oversight, not coding.

This molecule uses wisp storage (.beads-wisp/) for ephemeral patrol state.
Persistent state (nudge counts, handoffs) is stored in a witness handoff bead.


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.


Track merge requests as beads (type=merge-request)

Currently MRs are tracked in .gastown/refinery.json. For HOP audit trail and entity CV tracking, merge requests should be Beads entries with type=merge-request. This enables:
- Full audit trail of what was merged, when, by whom
- Entity chain contributions (who validated what)
- Cross-rig visibility of merge activity

The refinery would create an MR bead when work enters the queue, update status as it progresses (open → in_progress → merged/rejected).

Part of Beads-as-data-plane vision from HOP.


Add witness plugin hook support

Implement plugin directories for witness patrol.

Structure:
  <rig>/plugins/witness/
  ├── pre-inspection/
  │   └── stale-branch-check/
  │       └── CLAUDE.md
  └── post-action/
      └── mq-health/
          └── CLAUDE.md

run-plugins step scans these directories and bonds mol-plugin-runner for each.

Tmux wrapper: session operations

Wrapper for tmux session operations via subprocess.

## Interface

```go
type Tmux struct{}

func NewTmux() *Tmux

// Session lifecycle
func (t *Tmux) NewSession(name, workDir string) error
func (t *Tmux) KillSession(name string) error
func (t *Tmux) HasSession(name string) (bool, error)
func (t *Tmux) ListSessions() ([]string, error)

// Session interaction
func (t *Tmux) SendKeys(session, keys string) error
func (t *Tmux) CapturePane(session string, lines int) (string, error)
func (t *Tmux) AttachSession(session string) error

// Window operations (if needed)
func (t *Tmux) SelectWindow(session string, index int) error
```

## Session Naming

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

## Implementation

- Shell out to tmux binary
- CapturePane uses `tmux capture-pane -p -t <session> -S -<lines>`
- SendKeys uses `tmux send-keys -t <session> '<keys>' Enter`

## Error Handling

- "no server running": tmux not started (not an error for HasSession)
- "session not found": session doesn't exist
- Wrap all tmux errors with context

## Environment

Requires TMUX_TMPDIR or uses default socket. Don't assume tmux is running.


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.

Agent parking and resuming

Implement gt park and gt resume commands. Agent parks work on a gate, state persists across sessions. When gate condition met, Deacon sends wake mail. Agent resumes from parked state. Critical for async workflows.


Activity feed from wisp state: gt patrol status

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

## Problem

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

## Desired Commands

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

## Data Sources

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

## Use Cases

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

- Beads: implement but create PR instead of pushing to main

### mol-ready-work-aggressive

   - 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)

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

Add neighbor-check steps to all patrol molecules

Part of the 'Gas Town is a Village' antifragility design.

Every patrol molecule should include optional neighbor-checking:
- Deacon checks Witness and Refinery health
- Witness checks Refinery health
- Refinery checks Witness health
- Polecats can peek other polecats

Use gt peek to check health states.
If stuck neighbor found, can nudge or escalate.

This creates distributed monitoring - no single point of failure.


Molecule Algebra: Work Composition DSL

Implement the molecule algebra - a declarative language for composing, transforming, and executing structured work. Enables mechanical composition without AI.

The Three Phases: Rig → Cook → Run

- **Rig**: Source-level composition (formula YAML with extends/compose)
- **Cook**: Instantiation (formula → proto → mol/wisp)
- **Run**: Execution (agents complete steps)

Two Composition Operators:
- **Rig** operates on formulas (source level)
- **Bond** operates on artifacts (protos, mols, wisps)

Key components:
- Formulas: YAML source with composition rules (.formula.yaml)
- Cook: Pre-expand macros/aspects to flat proto
- Phase verbs (pour, wisp)
- Bond: Artifact-level polymorphic composition
- Composition operators (sequence, parallel, branch, loop, gate)
- Advice operators (before, after, around - Lisp style)
- Expansion operators (macros like Rule of Five)
- Aspects (AOP cross-cutting concerns)

See docs/rig-cook-run.md for the lifecycle spec.
See docs/molecule-algebra.md for full algebra specification.

tmux notifications: display-message too subtle, use send-keys instead

## Problem

`tmux display-message` notifications are not visible enough - they appear briefly in the status bar and are easy to miss.

## Current Behavior

router.go uses:
```go
r.tmux.DisplayMessageDefault(sessionID, notification)
```

## What Works

Sending echo commands directly to the terminal:
```bash
tmux send-keys -t <session> "echo '📬 NEW MAIL from mayor'" Enter
```

## Proposed Fix

Change notification method to send visible output to the terminal, perhaps with a box/banner:
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📬 NEW MAIL from mayor
Subject: <subject>
Run: bd mail inbox
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

## Considerations

- This interrupts the terminal output (acceptable for important mail)
- Could check if Claude is mid-response and queue notification
- Or use tmux popup if available

Additional issues:
1. Enter key not sent properly when chained with send-keys
2. Need to debounce and send Enter separately
3. Correct pattern: send text, sleep briefly, then send Enter


gt channel publish command

New CLI command for ephemeral broadcast to channels.

## Deliverables

1. New command: gt channel publish <channel> <message>

2. Resolve channel to running sessions
3. Nudge each session with message
4. Report delivery status

## Usage
```bash
gt channel publish #town "Handoff in 5 minutes"
gt channel publish #rig/gastown "Merge queue paused"
```

## Dependencies
- #channel resolution (gt-???)

## Acceptance
- Command works with #channel syntax
- Message delivered to running sessions
- Clear output showing delivery status

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.


Design: Collapse mail into beads

## Proposal

Replace the separate mail system (JSONL inboxes) with beads issues using a naming convention.

## Rationale

If all state should be in beads (work items, swarm state, dependencies), why have a separate system for messages? Mail is just:
- Handoffs (agent → self)
- Commands (Mayor → Refinery)
- Escalations (Witness → Mayor)

These can all be beads issues with a special prefix.

## Design

### Convention
- Messages use `@-` prefix: `@-witness-1734012345`
- Assignee = recipient
- Status: open = unread, closed = read/acknowledged
- Priority 0 = urgent

### Commands (thin wrappers)
```bash
gt mail send witness -s "Subject" -m "Body"
  → bd create --prefix=@ --title="Subject" --assignee=witness --description="Body"

gt mail inbox
  → bd list --prefix=@ --assignee=$(gt whoami) --status=open

gt mail read @-abc
  → bd show @-abc && bd close @-abc
```

### Notification
Daemon watches for new `@-` issues and pokes relevant sessions.
Or: agents poll on heartbeat (simpler).

## What We Remove
- `mail/inbox.jsonl` files
- Mail JSONL read/write code
- Separate delivery mechanism

## What We Keep
- `gt mail` CLI (as wrapper)
- Handoff semantics
- Notification (via daemon or polling)

## Benefits
- One system, one sync, one query interface
- All communication in git history
- Simpler architecture

## Risks
- Beads prefix filtering must be efficient
- Namespace collision with user prefixes
- Performance for high-frequency messages (probably fine for handoffs)

## Decision Point
Do we need first-class mail support in beads (`bd mail` commands) or is convention sufficient?

Feed-Based Wake Model for Patrol Agents

## The Paradigm Shift

> **Backoff is not about polling less. It is about waiting for signals with a timeout.**

This epic captures the shift from time-driven to event-driven patrol wake.

## Key Insight (Recovered from 2025-12-29 session crash)

The Beads activity feed (bd activity --follow) is the universal data plane for
wake signals. Every meaningful action creates a beads mutation; agents subscribe to
the feed and wake within ~500ms. The timeout is just a safety net.

**OLD**: Time-driven. Wake because time passed. Poll less when idle.
**NEW**: Event-driven. Wake because signal arrived. Timeout is safety net.

## Architecture

ANY MUTATION:
  bd create/update/close -> issues.jsonl mutation
                        -> bd activity --follow sees it (~500ms)
                        -> All subscribed agents wake immediately

PATROL AGENT:
  Runs bd activity --follow as background source
  Any output line = wake signal
  Timeout expiry = safety net (not primary wake)

## Wake Sources (Priority Order)

| Source | Latency | Purpose |
|--------|---------|---------|
| Feed | ~500ms | Primary - any beads mutation |
| Nudge | Instant | Explicit wake (startup hooks) |
| Timeout | Backoff | Safety net for missed signals |
| Daemon | 5-60min | GUPP backstop, session recovery |

## Key Design Decisions

1. No wake_on conditions - signals carry no semantic meaning. Just wake up.
   Agent discovers reality by checking mail, beads, hook, git state.

2. Read-only commands do not wake - gt status, bd show create no mutations.

3. Daemon is recovery-focused - catches edge cases (GUPP violations, dead sessions).

4. Keepalive file deprecated - the feed replaces the keepalive mechanism.

Deacon marching orders: pinned bead with rounds molecule

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

## Concept

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

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

## Pinned Bead Structure

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

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

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

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

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

## Reading Marching Orders

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

## Updating the Kernel

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

## Bootstrap

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


Phase 4: Deacon Patrol Loop

$(cat /tmp/phase4.md)


Gate issue type and bd gate create

Add type=gate to beads schema. Implement bd gate create command with --await flag. Gates are special issues that represent wait conditions. Example: bd gate create --await timer:5m --title 'Wait for cooldown'


Day 1.4b: Create Deacon agent bead

Create gt-deacon agent bead for the Deacon (daemon beacon).

The Deacon is a separate Claude Code agent from Mayor:
- Receives the ONLY mechanical daemon heartbeats in the system
- Runs town plugins, cleanup, and monitoring
- Has own top-level directory: ~/gt/deacon/
- No rig preassignment (town-level, like Mayor)
- role_type: deacon

Agent bead structure:
```yaml
id: gt-deacon
type: agent
entity_platform: gastown
entity_org: steveyegge
entity_id: deacon
hook_bead: null  # or current patrol wisp
role_bead: gt-deacon-role
state: idle
role_type: deacon
```

Must be created alongside mayor, witness, refinery agent beads.

Dogs: Deacon's Helper Workers

## Overview

Dogs are reusable workers managed by the Deacon for infrastructure and cleanup tasks.
They parallel how Polecats serve the Witness, but at town level with cross-rig scope.

## Key Concepts

- **Dogs**: Deacon-managed, reusable, infrastructure/cleanup tasks
- **Kennel**: Where dogs live (`deacon/dogs/`)
- **Multi-rig worktrees**: Dogs have worktrees into multiple rigs for cross-rig work

## Cats vs Dogs

| Aspect | Polecats | Dogs |
|--------|----------|------|
| Manager | Witness | Deacon |
| Scope | Per-rig | Town (cross-rig) |
| Lifecycle | Ephemeral | Reusable |
| Work | Features | Infrastructure |
| Location | `<rig>/polecats/` | `deacon/dogs/` |

## Implementation

### Phase 1: Dog Infrastructure
- `gt dog add/remove/list/call/status` commands
- Kennel directory structure (`~/gt/deacon/dogs/`)
- Multi-rig worktree creation
- Dog state tracking

### Phase 2: Deacon Dispatch
- Sling support for `deacon/dogs` target
- Pool management (spawn/retire logic)
- Completion mail handling

### Phase 3: Infrastructure Formulas
- mol-convoy-cleanup
- mol-dep-propagate
- mol-digest-generate

### Phase 4: Deacon Refactor
- Patrol becomes detect → dispatch
- Heavy work moves to dog slings

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

Molecule Phase Terminology Documentation

Document the three-phase molecule lifecycle with consistent terminology:

## The Phases (States of Matter)

| Phase | State | Nature |
|-------|-------|--------|
| **Proto** | Solid/Crystal | Frozen template, static definition in catalog |
| **Mol** | Liquid | Reified instance, malleable, tracked in git (durable) |
| **Wisp** | Gas | Evaporates after squash, ephemeral orchestration |

## Documentation Gaps Identified

### High Priority
1. Update vision.md Steam Engine metaphor to use proto/mol/wisp terminology
2. Add lifecycle diagram: Proto → bond → Mol or Wisp → squash → Digest
3. Document Go types for phases (ProtoMolecule, etc.)
4. Document .beads-ephemeral/ structure and purpose

### Medium Priority
5. Update CLAUDE.md files (polecat, witness, refinery) with molecule workflow
6. Document bd mol bond/squash/burn CLI API with examples
7. Add polecat guide: Executing molecules and generating summaries

### Low Priority
8. Add terminology glossary to architecture.md
9. Create troubleshooting playbook for stuck molecules
10. Add reference diagrams for state transitions

## Current State
- architecture.md has good molecule basics but uses inconsistent terminology
- vision.md has Steam Engine metaphor (proto=fuel, wisp=steam, digest=distillate)
- molecules.md has detailed reference but needs phase clarity
- builtin_molecules.go has 8 molecules but no phase documentation in code


Burn and respawn or loop

End of patrol cycle decision.

If context is LOW:
- Burn this wisp (no audit trail needed for patrol cycles)
- Sleep briefly to avoid tight loop (30-60 seconds)
- Return to inbox-check step

If context is HIGH:
- Burn wisp with summary digest
- Exit cleanly (daemon will respawn fresh Witness)

```bash
bd mol burn   # Destroy ephemeral wisp
```

The daemon ensures Witness is always running.


Design: Failure modes and recovery

Document failure modes and recovery strategies for Gas Town operations.

## Critical Failure Modes

### 1. Agent Crash Mid-Operation

**Scenario**: Polecat crashes while committing, Witness crashes while verifying

**Detection**:
- Session suddenly gone (tmux check fails)
- State shows 'working' but no session
- Heartbeat stops (for Witness)

**Recovery**:
- Doctor detects via ZombieSessionCheck
- Capture any recoverable state
- Reset agent state to 'idle'
- For Witness: auto-restart via supervisor or manual gt witness start

### 2. Git State Corruption

**Scenario**: Merge conflict, failed rebase, detached HEAD

**Detection**:
- Git commands fail
- Dirty state that won't commit
- Branch diverged from origin

**Recovery**:
- gt doctor reports git health issues
- Manual intervention recommended
- Severe cases: remove clone, re-clone

### 3. Beads Sync Conflict

**Scenario**: Two polecats modify same issue

**Detection**:
- bd sync fails with conflict
- Beads tombstone mechanism handles most cases

**Recovery**:
- Beads has last-write-wins semantics
- bd sync --force in extreme cases
- Issues may need manual dedup

### 4. Tmux Failure

**Scenario**: Tmux server crashes, socket issues

**Detection**:
- All sessions inaccessible
- "no server running" errors

**Recovery**:
- Kill any orphan processes
- tmux kill-server && tmux start-server
- All agent states reset to idle
- Re-spawn active work

### 5. Claude API Issues

**Scenario**: Rate limits, outages, context limits

**Detection**:
- Sessions hang or produce errors
- Repeated failure patterns

**Recovery**:
- Exponential backoff (handled by Claude Code)
- For context limits: session cycling (mail-to-self)
- For outages: wait and retry

### 6. Disk Full

**Scenario**: Clones, logs, or beads fill disk

**Detection**:
- Write operations fail
- git/bd commands error

**Recovery**:
- Clean up logs: rm ~/.gastown/logs/*
- Remove old polecat clones
- gt doctor --fix can clean some cruft

### 7. Network Failure

**Scenario**: Can't reach GitHub, API servers

**Detection**:
- git fetch/push fails
- Claude sessions hang

**Recovery**:
- Work continues locally
- Queue pushes for later
- Sync when connectivity restored

## Recovery Principles

1. **Fail safe**: Prefer stopping over corrupting
2. **State is recoverable**: Git and beads have recovery mechanisms
3. **Doctor heals**: gt doctor --fix handles common issues
4. **Emergency stop**: gt stop --all as last resort
5. **Human escalation**: Some failures need Overseer intervention

## Implementation

- Document each failure mode in architecture.md
- Ensure doctor checks cover detection
- Add recovery hints to error messages
- Log all failures for debugging

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

GGT is missing most polecat management commands that PGT has.

Missing Commands:
- gt polecat add <rig> <name> - Add polecat to rig (creates clone)
- gt polecat list [<rig>] - List polecats with state
- gt polecat info <polecat> - Show detailed info
- gt polecat wake <polecat> - Mark available
- gt polecat sleep <polecat> - Mark unavailable
- gt polecat decommission <polecat> - Remove polecat safely

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

Notes:
- spawn exists but doesn't cover management
- wake/sleep are in polecat manager but not CLI
- decommission should check for uncommitted work


mol sling command: attach molecule to agent hook

Add `gt mol sling <molecule-id>` command to attach a molecule to the current agent's hook.

## Behavior

```bash
gt mol sling mol-witness-patrol
```

1. Find agent identity from cwd (witness, polecat, crew, etc.)
2. Find or create agent's handoff bead
3. Attach molecule to handoff bead (attached_molecule field)
4. Create root issue for this molecule instance
5. Instantiate molecule steps under the root

## Difference from mol attach

- `mol attach` attaches to an existing pinned bead
- `mol sling` creates a fresh instance for execution

## Output

```
🧬 Slung mol-witness-patrol on gastown/witness
  Instance: gt-xyz (9 steps)
  First step: inbox-check
```

## Implementation

- Reuse InstantiateMolecule from molecule.go
- Create wrapper issue for the instance
- Set attached_molecule on handoff bead

Day 2.7: Bootstrap creates agent beads

Bootstrap commands must create agent beads for ZFC compliance.

## Problem
- `gt install` doesn't create Deacon/Mayor agent beads
- `gt rig add` doesn't create Witness/Refinery agent beads
- `gt doctor` doesn't verify agent beads exist
- Current beads were created manually (not reproducible)

## Impact
Patrol ignition (gt-qpoxz) depends on agent beads existing.
Without bootstrap creating them, fresh installs will fail.

## Required
1. gt install: Create gt-deacon and gt-mayor beads
2. gt rig add: Create gt-witness-<rig> and gt-refinery-<rig> beads
3. gt doctor: Add agent-beads-exist check
4. gt doctor --fix: Create missing agent beads

Polecat Arm (arm-toast)

Single polecat inspection and action cycle.

This molecule is bonded dynamically by mol-witness-patrol's survey-workers step.
Each polecat being monitored gets one arm that runs in parallel with other arms.

## Variables

| Variable | Required | Description |
|----------|----------|-------------|
| polecat_name | Yes | Name of the polecat to inspect |
| rig | Yes | Rig containing the polecat |

## Step: capture
Capture recent tmux output for toast.

```bash
tmux capture-pane -t gt-gastown-toast -p | tail -50
```

Record:
- Last activity timestamp (when was last tool call?)
- Visible errors or stack traces
- Completion indicators ("Done", "Finished", etc.)

## Step: assess
Categorize polecat state based on captured output.

States:
- **working**: Recent tool calls, active processing
- **idle**: At prompt, no recent activity
- **error**: Showing errors or stack traces
- **requesting_shutdown**: Sent LIFECYCLE/Shutdown mail
- **done**: Showing completion indicators

Calculate: minutes since last activity.
Needs: capture

## Step: load-history
Read nudge history for toast from patrol state.

```
nudge_count = state.nudges[toast].count
last_nudge_time = state.nudges[toast].timestamp
```

This data was loaded by the parent patrol's load-state step and passed
to the arm via the bonding context.
Needs: assess

## Step: decide
Apply the nudge matrix to determine action for toast.

| State | Idle Time | Nudge Count | Action |
|-------|-----------|-------------|--------|
| working | any | any | none |
| idle | <10min | any | none |
| idle | 10-15min | 0 | nudge-1 (gentle) |
| idle | 15-20min | 1 | nudge-2 (direct) |
| idle | 20+min | 2 | nudge-3 (final) |
| idle | any | 3 | escalate |
| error | any | any | assess-severity |
| requesting_shutdown | any | any | pre-kill-verify |
| done | any | any | pre-kill-verify |

Nudge text:
1. "How's progress? Need any help?"
2. "Please wrap up soon. What's blocking you?"
3. "Final check. Will escalate in 5 min if no response."

Record decision and rationale.
Needs: load-history

## Step: execute
Take the decided action for toast.

**nudge-N**:
```bash
tmux send-keys -t gt-gastown-toast "{{nudge_text}}" Enter
```

**pre-kill-verify**:
```bash
cd polecats/toast
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred
```
If clean: kill session, remove worktree, delete branch
If dirty: record failure, retry next cycle

**escalate**:
```bash
gt mail send mayor/ -s "Escalation: toast stuck" -m "..."
```

**none**: No action needed.

Record: action taken, result, updated nudge count.
Needs: decide

## Output

The arm completes with:
- action_taken: none | nudge-1 | nudge-2 | nudge-3 | killed | escalated
- result: success | failed | pending
- updated_state: New nudge count and timestamp for toast

This data feeds back to the parent patrol's aggregate step.

Agent beads hook_bead field never populated

## Problem

The witness patrol formula expects polecat agent beads to have:

  hook_bead: <current-work-id>

This field is used by the witness to see what the polecat is working on.

But looking at the code, hook_bead is never set:

1. Polecat agent bead created (polecat/manager.go:167-170) - no hook_bead
2. reportAgentState called (prime.go:1067) - passes nil for hookBead
3. UpdateAgentState preserves existing hook_bead if nil (beads.go:633-635)

Since hook_bead starts empty and is never updated, the witness cannot use
agent beads to see what polecats are working on.

## Found in commit

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

## Related to

- gt-0lop3 (Agent state lifecycle incomplete for polecats)

## Suggested fix

When a polecat is assigned work (via gt sling or similar), update the agent
bead's hook_bead field:

  bd.UpdateAgentState(agentID, 'running', &hookBeadID)

Witness: bond mol-polecat-arm when discovering polecat

When witness discovers a polecat during healthCheck(), bond a mol-polecat-arm child.

## Changes to witness/manager.go

In healthCheck() when iterating polecats:
1. Check if arm already exists for this polecat (arm-{name})
2. If not, call: gt mol bond mol-polecat-arm --parent=$PATROL_ID --ref=arm-{name} --var polecat_name={name} --var rig={rig}
3. Track arm issue ID in handoff state

## Arm Lifecycle

- Created when polecat first seen
- Updated as inspection happens (nudges, state changes)
- Closed when polecat cleaned up

## Deduplication

Check handoffState.WorkerStates[name].ArmID before creating.
Needs: gt-59zd.3


Town & Rig Management: install, doctor, federation

Reify the Gas Town installation as a first-class concept.

## Goals
- Installable: gt install [path] creates complete installation
- Diagnosable: gt doctor checks and fixes issues
- Federable: Clone town to VMs with central control

## Architecture Reference

See docs/architecture.md for full design, especially:
- Directory structure (Town Level / Rig Level sections)
- Configuration (town.json, rigs.json schemas)
- Key design decisions (visible config dir, decentralized agents)


mol-deacon-patrol

Mayor's daemon patrol loop.

The Deacon is the Mayor's background process that runs continuously, handling callbacks, monitoring rig health, and performing cleanup. Each patrol cycle runs these steps in sequence, then loops or exits.

## Second-Order Monitoring

Witnesses send WITNESS_PING messages to verify the Deacon is alive. This
prevents the "who watches the watchers" problem - if the Deacon dies,
Witnesses detect it and escalate to the Mayor.

The Deacon's agent bead last_activity timestamp is updated during each patrol
cycle. Witnesses check this timestamp to verify health.


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

Add gate timeout tracking and notification

Implement timeout and notification logic for gates.

## Timeout Behavior
1. Gate created with timeout (e.g., 30m)
2. Deacon tracks elapsed time during patrol
3. If timeout reached:
   - Notify all waiters: 'Gate timed out'
   - Close gate with timeout reason
   - Waiter can retry, escalate, or fail gracefully

## Notification
- Use gt mail send to notify waiters
- Include gate ID, await type, and reason in message
- Support multiple waiters notification

## Moved from beads
Originally bd-ykqu. Gate notifications are Deacon's job in gastown.

mol-ready-work: graceful GitHub/label handling

## Summary

mol-ready-work assumes:
- GitHub repo exists with gh CLI configured
- Labels 'untriaged' and 'triaged' exist

Should handle gracefully:
1. No GitHub repo (beads-only project) → skip GH backlogs
2. Missing labels → skip that backlog tier, don't error
3. gh CLI not authenticated → warn and skip GH backlogs

## Implementation
Add checks in scan-backlogs step:
```bash
# Check if gh is available and authenticated
if gh auth status &>/dev/null; then
  # scan GH backlogs
fi
```

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

Molecule await-signal step type

Add await-signal as a molecule step type for patrol agents.

## Step Definition

```toml
[[steps]]
id = "await-signal"
type = "wait"
backoff = { base = "30s", multiplier = 2, max = "10m" }
description = "Wait for signal, then check reality"
```

## Behavior

1. Sleep for current backoff interval
2. Wake immediately on nudge (or timeout expires)
3. Proceed to next step (check-reality)
4. If no work found, loop back with increased backoff
5. If work found, reset backoff to base

## Implementation Options

A. Formula-level: Define in TOML, agent interprets
B. Code-level: Agent implements wait loop with backoff

Option A is cleaner but needs formula parser support.
Option B works now but less declarative.

## Used By

gt sling: nudge witness+refinery when dispatching to polecat

When gt sling dispatches work to a polecat, wake the rig's witness and refinery.

## Boot+Nudge Pattern

```go
// After successful polecat dispatch
func wakeRigAgents(rig string) {
    // Level 2: Start if asleep
    exec.Command("gt", "rig", "boot", rig).Run()

    // Level 1: Clear backoff if running
    t := tmux.NewTmux()
    t.NudgeSession(fmt.Sprintf("gt-%s-witness", rig), "wake")
    t.NudgeSession(fmt.Sprintf("gt-%s-refinery", rig), "wake")
}
```

## Graceful Behavior

- `gt rig boot` is idempotent (no-op if already running)
- Nudge failures are silent (session might not exist yet)
- Agents discover what happened by checking reality

## Reference

See ~/gt/docs/patrol-system-design.md (Two-Level Wake section)


Polecat Arm (arm-toast)

Single polecat inspection and action cycle.

This molecule is bonded dynamically by mol-witness-patrol's survey-workers step.
Each polecat being monitored gets one arm that runs in parallel with other arms.

## Variables

| Variable | Required | Description |
|----------|----------|-------------|
| polecat_name | Yes | Name of the polecat to inspect |
| rig | Yes | Rig containing the polecat |

## Step: capture
Capture recent tmux output for toast.

```bash
tmux capture-pane -t gt-gastown-toast -p | tail -50
```

Record:
- Last activity timestamp (when was last tool call?)
- Visible errors or stack traces
- Completion indicators ("Done", "Finished", etc.)

## Step: assess
Categorize polecat state based on captured output.

States:
- **working**: Recent tool calls, active processing
- **idle**: At prompt, no recent activity
- **error**: Showing errors or stack traces
- **requesting_shutdown**: Sent LIFECYCLE/Shutdown mail
- **done**: Showing completion indicators

Calculate: minutes since last activity.
Needs: capture

## Step: load-history
Read nudge history for toast from patrol state.

```
nudge_count = state.nudges[toast].count
last_nudge_time = state.nudges[toast].timestamp
```

This data was loaded by the parent patrol's load-state step and passed
to the arm via the bonding context.
Needs: assess

## Step: decide
Apply the nudge matrix to determine action for toast.

| State | Idle Time | Nudge Count | Action |
|-------|-----------|-------------|--------|
| working | any | any | none |
| idle | <10min | any | none |
| idle | 10-15min | 0 | nudge-1 (gentle) |
| idle | 15-20min | 1 | nudge-2 (direct) |
| idle | 20+min | 2 | nudge-3 (final) |
| idle | any | 3 | escalate |
| error | any | any | assess-severity |
| requesting_shutdown | any | any | pre-kill-verify |
| done | any | any | pre-kill-verify |

Nudge text:
1. "How's progress? Need any help?"
2. "Please wrap up soon. What's blocking you?"
3. "Final check. Will escalate in 5 min if no response."

Record decision and rationale.
Needs: load-history

## Step: execute
Take the decided action for toast.

**nudge-N**:
```bash
tmux send-keys -t gt-gastown-toast "{{nudge_text}}" Enter
```

**pre-kill-verify**:
```bash
cd polecats/toast
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred
```
If clean: kill session, remove worktree, delete branch
If dirty: record failure, retry next cycle

**escalate**:
```bash
gt mail send mayor/ -s "Escalation: toast stuck" -m "..."
```

**none**: No action needed.

Record: action taken, result, updated nudge count.
Needs: decide

## Output

The arm completes with:
- action_taken: none | nudge-1 | nudge-2 | nudge-3 | killed | escalated
- result: success | failed | pending
- updated_state: New nudge count and timestamp for toast

This data feeds back to the parent patrol's aggregate step.

Patrol 20: All agents healthy - triggering handoff


BUG: gt handoff --dry-run still sends mail

In handoff.go, the dry-run check happens AFTER sendHandoffMail() is called. This means --dry-run still sends mail.

**Location**: handoff.go L126-143

**Observed**: Testing with `gt handoff --dry-run -s 'Test' -m 'Message'` actually sent mail to mayor.

**Fix**: Move mail sending inside the non-dry-run block, or check dry-run first.

```go
// Current (buggy):
if handoffSubject \!= "" || handoffMessage \!= "" {
    sendHandoffMail(...)  // Executes even in dry-run\!
}
if handoffDryRun {        // Too late

Refinery patrol: Add sibling-check step

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

## Implementation

1. Add `sibling-check` step to mol-refinery-patrol (early in cycle)
2. Use `gt peek <rig>/witness 20` to check Witness output
3. Look for signs of health:
   - Recent activity (tool calls, log messages)
   - No error stack traces
   - Responsive to pings
4. If Witness seems stuck:
   - Send status request mail
   - Note for potential escalation
   - Don't block Refinery work

## Acceptance
- Refinery checks Witness each patrol cycle
- Anomalies logged
- Non-blocking (Refinery continues even if Witness is down)

gt nudge doesn't work with crew addresses

## Bug

`gt nudge beads/crew/dave "message"` fails because it uses the polecat session manager which produces wrong session names.

## Expected
Session name: `gt-beads-crew-dave` (hyphen)

## Actual
Session name: `gt-beads-crew/dave` (slash, from polecat manager)

## Root Cause

In nudge.go line 46-57, parseAddress returns polecatName=`crew/dave`, then SessionName keeps the slash.

## Fix

Detect `crew/` prefix and use crewSessionName() instead.


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.

Remove schedule/phase terminology from code

Temporal/schedule language in identifiers is an anti-pattern.

## Found Issues

### beads repo
- `examples/multi-phase-development/` directory
  - Rename to `examples/dependency-sequenced-work/` or similar

### gastown repo
- `internal/cmd/start.go` lines 178-195
  - Uses "Phase 1:", "Phase 2:", etc. in printf output
  - Change to descriptive names: "Interrupting agents...", "Requesting handoff...", etc.

- `internal/swarm/landing.go` lines ~50-70
  - Comments say "// Phase 1: Stop all polecat sessions"
  - Change to "// Step: Stop all polecat sessions" or just remove phase labels

## Why This Matters

Phase/version language in names:
1. Implies a fixed schedule (antithetical to dependency-driven work)
2. Creates confusion with molecule "phases" (solid/liquid/gas)
3. Encourages temporal thinking that leads to backwards dependencies

## What To Keep

- Molecule phase terminology (pour/wisp/proto) - this is chemistry, not scheduling
- Version fields inside files (version: 1) - this is semantic versioning

Consider gt polecats --status=idle for swarm dispatch

The dispatch-swarm-work step in mol-witness-patrol uses a complex jq command to find idle polecats:

```bash
bd list --type=agent --json | jq '[.[] | select(.description | contains("role_type: polecat") and contains("agent_state: idle"))]'
```

Consider adding a dedicated command:
```bash
gt polecats <rig> --status=idle
```

Benefits:
- Simpler for formula authors
- Encapsulates agent bead schema details
- Could add --json output for programmatic use

Low priority - the jq approach works, this is just ergonomics.

Merge queue: per-rig queue management

Per-rig merge queue for coordinating polecat work.

## Concept

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

## Data Model

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

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

## Interface

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

func NewMergeQueue(rig *Rig) *MergeQueue

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

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

## Queue Storage

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

## Git Coordination

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

## Conflict Handling

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

    URL    string `json:"url"`
    Branch string `json:"branch"`
}
```

## Response Types (streaming NDJSON)

```go
type WorkEvent struct {
    Type     string `json:"type"`  // status, log, progress, result, error
    Status   string `json:"status,omitempty"`
    Line     string `json:"line,omitempty"`
    Percent  int    `json:"percent,omitempty"`
    Branch   string `json:"branch,omitempty"`
    PRURL    string `json:"pr_url,omitempty"`
    Code     string `json:"code,omitempty"`
    Message  string `json:"message,omitempty"`
}

type WorkResult struct {
    Status  string `json:"status"`  // done, failed
    Branch  string `json:"branch"`
    PRURL   string `json:"pr_url,omitempty"`
    Error   string `json:"error,omitempty"`
}
```

## Files

CLI API Audit: gt and bd command structure review before OSS launch

# CLI API Audit for OSS Launch

Before launching Gas Town + Beads as an SDK, we need to ensure the command-line
API is intelligently designed, consistent, intuitive, and structurally sound.

## Current State Audit

### gt (Gas Town) - 50+ top-level commands

**Agent Lifecycle:**

- `gt polecat` - worker management (subcommands: add, remove, list, etc.)
- `gt crew` - persistent workspace management
- `gt spawn` - create polecat with work

**Work Lifecycle:**
- `gt spawn` - assign work to new polecat
- `gt sling` - hook work + start immediately
- `gt hook` - attach work durably
- `gt handoff` - pass work to fresh session
- `gt done` - signal work complete
- `gt release` - release stuck issues

**Infrastructure:**
- `gt daemon`, `gt up`, `gt down`, `gt start`, `gt stop`, `gt shutdown`
- `gt init`, `gt install`, `gt doctor`

**Communication:**
- `gt mail` (subcommands: send, inbox, read, etc.)
- `gt nudge`, `gt broadcast`

**Molecules:**
- `gt molecule` / `gt mol` (17 subcommands!)

### bd (Beads) - Well-categorized but some sprawl

**Core CRUD:**
- `bd create`, `bd show`, `bd update`, `bd close`, `bd list`

**Molecules:**
- `bd mol` (5 subcommands: catalog, show, bond, run, distill)
- `bd wisp` (3 subcommands: create, gc, list)
- `bd pour` (top-level alias for instantiation)
- `bd cook` (compile formula to proto)

**Hook/Pin:**
- `bd pin` - attach mol to agent hook
- `bd unpin` - remove from hook
- `bd hook` - inspect what's on hook

## Structural Concerns

### 1. gt is sprawling (50+ top-level commands)

Many commands could be subcommands:
```
# Current                      # Could be
gt up/down/start/stop         gt daemon {up|down|start|stop}
gt spawn/sling/hook/handoff   gt work {spawn|sling|hook|handoff}
gt mayor/deacon/witness       gt agent {mayor|deacon|witness|...}
```

### 2. Overlap between gt and bd

| Concept | gt | bd |
|---------|----|----|
| Hook | `gt hook` | `bd pin`, `bd hook` |
| Mail | `gt mail` | `bd mail` (delegates) |
| Molecules | `gt mol` (17 cmds) | `bd mol` (5 cmds) |

Which owns what? User confusion likely.

### 3. Naming inconsistencies

- `gt polecat` (noun) vs `gt spawn` (verb) - both about polecats
- `gt done` vs `gt handoff` - both end work but different
- `bd mol run` vs `bd pour` - both instantiate

### 4. Subcommand depth decisions

**Good patterns:**
- `bd mol {catalog|show|bond|run|distill}` - coherent group
- `gt mail {send|inbox|read|archive}` - coherent group

**Questionable patterns:**
- `bd create --wisp` AND `bd wisp create` - two ways to do same thing
- `gt spawn --molecule X` AND `gt mol instantiate` - overlap

### 5. Flag vs subcommand guidelines needed

When to use flags vs subcommands?
- `--json` as flag ✓ (modifier)
- `--wisp` as flag for create? Or separate `bd wisp create`?
- `--molecule` on spawn? Or separate workflow?

## Recommendations to Evaluate

### A. Consolidate gt top-level commands

Group related commands:
```
gt agent {mayor|deacon|witness|refinery|polecat}
gt work {spawn|sling|hook|handoff|done}
gt infra {daemon|up|down|doctor}
```

### B. Clarify gt vs bd ownership

| Domain | Owner | Other defers |
|--------|-------|--------------|
| Issues | bd | gt uses bd |
| Agents | gt | bd doesn't touch |
| Molecules | bd mol | gt mol wraps for UX |
| Hooks | bd pin/hook | gt hook wraps |
| Mail | gt mail | bd mail delegates |

### C. Apply consistent naming

- All agent commands: nouns (`gt polecat`, `gt mayor`)
- All work commands: verbs (`gt spawn`, `gt sling`, `gt hook`)
- Avoid synonyms: pick one term and stick with it

### D. Flag vs subcommand rule

- Flags: modify behavior of command (`--json`, `--force`, `--wisp`)
- Subcommands: distinct operations (`mol run`, `mol squash`, `mol burn`)
- Exception: very common operations can have top-level aliases

## Tasks

1. [ ] Review gt command groupings - propose consolidation
2. [ ] Review bd command groupings - check for sprawl
3. [ ] Document gt vs bd ownership boundaries
4. [ ] Identify and resolve naming inconsistencies
5. [ ] Document flag vs subcommand decision criteria
6. [ ] Create migration plan for any breaking changes
7. [ ] Update help text to be consistent
8. [ ] Test agent UX: can Claude guess commands correctly?

## Success Criteria

- New user can guess command structure intuitively
- `gt --help` fits on one screen (or is well-categorized)
- No duplicate functionality between gt and bd
- Consistent naming throughout
- Claude agents can discover commands without documentation

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

Refinery emits activity events

Refinery emits events to activity stream for MQ lifecycle:

Events to emit:
- merge_started: When refinery begins processing an MR
- merged: When MR successfully merged to main
- merge_failed: When merge fails (conflict, tests, etc.)
- merge_skipped: When MR skipped (already merged, etc.)

Events should include: MR ID, worker, branch, timestamp, reason (for failures)

This replaces stats tracking in .runtime/refinery.json

gt rig reset --stale: Clear orphaned in_progress items

Reset in_progress issues when their assigned agent no longer exists.

## Problem
When polecats die without cleanup, their issues remain in_progress forever.
Need a way to bulk-reset these orphaned items.

## Command
```bash
gt rig reset --stale [--dry-run]
```

## Logic
For each in_progress issue in rig:
1. Parse assignee (e.g., "gastown/furiosa")
2. Map to tmux session name (gt-gastown-furiosa)
3. If session does NOT exist:
   - Reset status to "open"
   - Clear assignee
4. Exception: skip crew/* assignees (persistent identities)
   OR check if crew tmux session exists

## Output
```
Resetting stale work in gastown:
  gt-abc: gastown/furiosa (no session) → open
  gt-def: gastown/nux (no session) → open
  Skipped: gt-xyz: gastown/crew/max (persistent)
Reset 2 issues, skipped 1
```

ApplyBranches/ApplyGates mutate steps in place

ApplyBranches and ApplyGates claim to return a modified steps slice, but they actually mutate the original steps via the pointer map from buildStepMap().

```go
// ApplyBranches docstring says:
// Returns the modified steps slice (steps are modified in place for dependencies).
```

This is technically documented but violates the pattern established by ApplyLoops and ApplyAdvice which return new step slices.

Options:
1. Document explicitly that these functions mutate in place (current behavior)
2. Clone steps before modification for true immutability
3. Accept this as intentional since it's an optimization

The current behavior is safe because cook.go doesn't reuse the input slice, but could cause subtle bugs if callers expect immutability.

Recommend option 1 (document) or 2 (clone) for consistency.


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


Architecture: Decentralized rig structure with per-rig agents

## Decision

Adopt decentralized architecture where each rig contains all its agents (mayor/, witness/, refinery/, polecats/) rather than centralizing mayor clones at town level.

## Town Level Structure

```
~/ai/                              # Town root
├── config/                        # Town config (VISIBLE, not hidden)
│   ├── town.json                  # {"type": "town"}
│   ├── rigs.json                  # Registry of managed rigs
│   └── federation.json            # Wasteland config (future)
│
├── mayor/                         # Mayor's HOME at town level
│   ├── CLAUDE.md
│   ├── mail/inbox.jsonl
│   └── state.json
│
└── <rigs>/                        # Managed projects
```

## Rig Level Structure (e.g., wyvern)

```
wyvern/                            # Rig = clone of project repo
├── .git/info/exclude              # Gas Town adds: polecats/ refinery/ witness/ mayor/
├── .beads/                        # Beads (if project uses it)
├── [project files]                # Clean project code on main
│
├── polecats/                      # Worker clones
│   └── <name>/                    # Each is a git clone
│
├── refinery/
│   ├── rig/                       # Refinery's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
├── witness/                       # NEW: Per-rig pit boss
│   ├── rig/                       # Witness's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
└── mayor/
    ├── rig/                       # Mayor's clone for this rig
    └── state.json
```

## Key Decisions

1. **Visible config dir**: `config/` not `.gastown/` (models don't find hidden dirs)
2. **Witness per-rig**: Each rig has its own Witness (pit boss) with its own clone
3. **Mayor decentralized**: Mayor's clones live IN each rig at `<rig>/mayor/rig/`
4. **Minimal invasiveness**: Only `.git/info/exclude` modified, no commits to project
5. **Clone subdir name**: Keep `rig/` for consistency (refinery/rig/, witness/rig/, mayor/rig/)

## Role Detection

- Town root or mayor/ → Mayor (town level)
- Rig root → Mayor (canonical main)
- <rig>/mayor/rig/ → Mayor (rig-specific)
- <rig>/refinery/rig/ → Refinery
- <rig>/witness/rig/ → Witness
- <rig>/polecats/<name>/ → Polecat

## Migration from PGT

- `mayor/rigs/<rig>/` → `<rig>/mayor/rig/`
- `<rig>/town/` → eliminated (rig root IS the clone)
- Add `witness/` to each rig

Design: Swarm shutdown and worker cleanup

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

## Key Decisions

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

## Subtasks (implementation)

- gt-f8v: Witness pre-kill verification protocol
- gt-eu9: Witness session cycling and handoff
- gt-gl2: Mayor vs Witness cleanup responsibilities

Refactor gt swarm to use beads backing

Migrate gt swarm commands from .runtime/swarms.json to beads molecules.

Current gt swarm stores state in .runtime/swarms.json - violating discovery over tracking.
The refactored version should use bd swarm create/status to work with beads molecules.

Implementation:
- gt swarm create calls bd swarm create
- gt swarm status calls bd swarm status
- gt swarm list queries bd list --mol-type=swarm
- Remove .runtime/swarms.json dependency

CROSS-RIG DEPENDENCIES (must complete first in beads repo):
- bd-oxgi: mol_type schema field
- bd-fa1q: bd swarm create command
- bd-5x0j: bd swarm status command

gt mq list shows empty when MRs exist

The gt mq list command returns empty results even when merge requests exist in the queue.


Swarm status doesn't update after task completions

During swarm bd-784c, the swarm status remained at '9% (1/11 tasks merged)' even after 5 tasks were completed and closed.

**Expected:**
Swarm status should reflect actual completion count, either by:
1. Polling issue status from beads
2. Updating when polecats close issues
3. Updating when commits are pushed to integration branch

**Impact:**
Coordinator had to manually check bd list to know actual progress.

gt sling: use mail queue for patrol roles (witness, refinery, deacon)

When slinging work to patrol agents, queue via mail instead of replacing hook.

**Rationale:**
Patrol agents run continuous loops. Replacing their hook with discrete work breaks patrol continuity - when the task completes, the patrol stops.

**New behavior for patrol roles (witness, refinery, deacon):**
1. Check if patrol is running (hook has patrol molecule attached)
2. If patrol running:
   - Don't touch hook (patrol stays pinned)
   - Send work assignment mail
   - Print 'Queued for next patrol cycle'
3. If patrol NOT running:
   - Start default patrol for that role (mol-witness-patrol, mol-refinery-patrol, mol-deacon-patrol)
   - Send work assignment mail
   - Print 'Started patrol and queued work'

**New flags:**
- --urgent: Interrupt current patrol cycle, process this work immediately
- --replace: Explicitly terminate patrol and pin discrete work (break-glass)

**No change for:**
- Polecat, Crew, Mayor (discrete task agents - current behavior)

**Dependencies:**
- Patrol templates must have 'check inbox' step (verify/add)
- Need to know default patrol molecule for each role

Optimize: Share stepMap across control flow operators

In ApplyControlFlow, both ApplyBranches and ApplyGates call buildStepMap() separately:

```go
func ApplyBranches(steps []*Step, compose *ComposeRules) ([]*Step, error) {
    stepMap := buildStepMap(steps)  // Called here
    ...
}

func ApplyGates(steps []*Step, compose *ComposeRules) ([]*Step, error) {
    stepMap := buildStepMap(steps)  // Called again here
    ...
}
```

This is inefficient for large formulas. Options:

1. Pass stepMap as a parameter to ApplyBranches/ApplyGates
2. Create an internal version that accepts stepMap, keep public API unchanged
3. Build once in ApplyControlFlow and pass down

Low priority since formula sizes are typically small.


Witness: Handle LIFECYCLE work-merged mail

Witness should process the `LIFECYCLE: work merged` notification from Refinery.

## Implementation

1. In Witness mail processing, add handler for subject containing "LIFECYCLE: work merged"
2. Parse worker name from mail body
3. Update polecat state to `merged` (new state - see sibling task)
4. Log completion for metrics
5. Worktree is now eligible for cleanup on next gc cycle

## Acceptance
- Witness correctly parses and handles work-merged mail
- Polecat state updated to merged
- No action taken if polecat already cleaned up (idempotent)


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 polecat remove --all: bulk polecat teardown

Currently gt polecat remove only accepts one polecat at a time. Need bulk operations:

## Requested
- `gt polecat remove gastown --all` - remove all polecats from a rig
- `gt polecat remove gastown/A gastown/B ...` - remove multiple by name

## Context
After a swarm completes, tearing down 20 polecats one at a time is tedious.
Ephemeral workers should be easy to create and destroy in bulk.

gt crew next: Return self when only window in cycle group

## Problem
`gt crew next --session 'gt-mayor'` returns exit code 1 when the Mayor is the only window in that cycle group.

## Expected Behavior
When an agent is the only member of its cycle group (or not in any configured cycle group), `gt crew next` should return the current session itself rather than failing.

## Context
- C-b n in Mayor's session triggers this command
- Currently only rig crews have configured cycle groups
- Mayor is not part of any crew cycle group, so it should just return itself

## Fix
If no other windows exist in the cycle group, return the current session name instead of error.
