Rename engineer-in-box to shiny across all docs

Systematic rename of mol-engineer-in-box to shiny throughout docs: molecular-chemistry.md, molecules.md, architecture.md, etc. The shiny name is now canonical per the Breaking Bad × Mad Max naming.

Duplicate of gt-8tmz.10 which is in the molecule algebra epic


Witness pre-kill verification protocol

Add pre-kill verification protocol to Witness CLAUDE.md template.

## Protocol for Witness Prompting

```markdown
## Pre-Kill Verification Protocol

Before killing any worker session, verify workspace is clean.

### Verification Steps

When a worker signals done:

1. **Capture worker state**:
```bash
town capture <polecat> "git status && git stash list && bd sync --status"
```

2. **Assess the output** (use your judgment):
- Is working tree clean?
- Is stash list empty?
- Is beads synced?

3. **Decision**:
- **CLEAN**: Proceed to kill session
- **DIRTY**: Send nudge with specific issues

### Nudge Templates

**Uncommitted Changes**:
```
town inject <polecat> "WITNESS CHECK: Uncommitted changes found. Please commit or discard: <files>. Signal done when clean."
```

**Beads Not Synced**:
```
town inject <polecat> "WITNESS CHECK: Beads not synced. Run 'bd sync' then commit. Signal done when complete."
```

### Kill Sequence

Only after verification passes:
```bash
town kill <polecat>
town sleep <polecat>
```

### Escalation

If worker fails verification 3+ times:
```bash
town mail send mayor/ -s "Escalation: <polecat> stuck" -m "Cannot complete cleanup after 3 attempts. Issues: <list>."
```
```

## Implementation

Add to WITNESS_CLAUDE.md template.


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)


Config package: Config, State types and JSON serialization

Config and state types with JSON serialization.

## Town Config (config/town.json)

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

## Rigs Registry (config/rigs.json)

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

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

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

## Agent State (*/state.json)

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

## Interface

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

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

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

## Validation

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


Extended addressing: Parse [machine:]rig/polecat

Extended addressing for cross-machine operations.

## Address Format

```
[machine:]rig/polecat
```

Examples:
- `wyvern/Toast` - Local machine, wyvern rig, Toast polecat
- `gcp-vm-1:wyvern/Toast` - Remote machine
- `wyvern/` - Broadcast to rig
- `gcp-vm-1:wyvern/` - Broadcast to remote rig

## Parser

```go
type Address struct {
    Machine  string  // empty = local
    Rig      string
    Polecat  string  // empty = broadcast
}

func ParseAddress(s string) (*Address, error)
func (a *Address) String() string
func (a *Address) IsLocal() bool
func (a *Address) IsBroadcast() bool
```

## Validation

```go
func (a *Address) Validate(registry *MachineRegistry) error
```
- Machine must exist in registry (if specified)
- Rig must exist on machine
- Polecat must exist (if specified)

## Usage

All CLI commands that take addresses use ParseAddress:
```go
// gt mail send gcp-vm-1:wyvern/Toast -s "Hello"
addr, _ := ParseAddress("gcp-vm-1:wyvern/Toast")
conn, _ := registry.Connection(addr.Machine)
// Use conn for operations
```

## Backward Compatibility

Existing `rig/polecat` addresses work unchanged (Machine defaults to local).


Workspace detection: Find() walking up directory tree

Find workspace root by walking up directory tree looking for Gas Town markers.

## Detection Logic

Walk up from current directory, looking for:
1. `config/town.json` - Primary marker (visible config dir per gt-iib)
2. `mayor/` directory at town level - Secondary marker

Stop at filesystem root if neither found.

## Interface

```go
// Find locates the town root from the given directory
func Find(startDir string) (string, error)

// FindOrError is like Find but returns a user-friendly error
func FindOrError(startDir string) (string, error)
```

## Return Values

- Success: Absolute path to town root
- Not found: Empty string + specific error
- Error: Empty string + wrapped error

## Edge Cases

- Symlinks: Follow them (use filepath.EvalSymlinks)
- Permissions: Return error if can't read directory
- Nested towns: Return nearest ancestor (shouldn't happen in practice
EOF
)


gt install command: Create workspace structure

Create Gas Town workspace structure.

## Command

```
gt install [path]
```

If path omitted, uses current directory.

## Created Structure

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

## Implementation

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

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

## Steps

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

## Error Cases

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

## Templates

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


Doctor framework: Check interface, Result types, Report

Framework for gt doctor health checks.

## Check Interface

```go
type Check interface {
    Name() string
    Description() string
    Run(ctx *CheckContext) *CheckResult
    Fix(ctx *CheckContext) error  // optional auto-fix
    CanFix() bool
}

type CheckContext struct {
    TownRoot string
    RigName  string  // empty for town-level checks
    Verbose  bool
}

type CheckResult struct {
    Status  CheckStatus
    Message string
    Details []string  // additional info
    FixHint string    // suggestion if not auto-fixable
}

type CheckStatus int
const (
    StatusOK CheckStatus = iota
    StatusWarning
    StatusError
)
```

## Report

```go
type Report struct {
    Timestamp time.Time
    Checks    []CheckResult
    Summary   ReportSummary
}

type ReportSummary struct {
    Total    int
    OK       int
    Warnings int
    Errors   int
}

func (r *Report) Print(w io.Writer, verbose bool)
```

## Doctor Runner

```go
type Doctor struct {
    checks []Check
}

func NewDoctor() *Doctor
func (d *Doctor) Register(check Check)
func (d *Doctor) Run(ctx *CheckContext) *Report
func (d *Doctor) Fix(ctx *CheckContext) *Report  // run with auto-fix
```

## Built-in Checks

Town-level (gt-f9x.5):
- ConfigExists, ConfigValid

    &RefineryExistsCheck{},
    &MayorCloneExistsCheck{},
    &PolecatClonesValidCheck{},
    &BeadsConfigValidCheck{},
}
```


Connection interface: Protocol for local/remote ops

Abstract interface for local vs remote (SSH) operations.

## Concept

Enable Gas Town to manage rigs on remote machines via SSH. The Connection interface abstracts whether operations happen locally or remotely.

## Interface

```go
type Connection interface {
    // Identification
    Name() string
    IsLocal() bool

    // File operations
    ReadFile(path string) ([]byte, error)
    WriteFile(path string, data []byte, perm os.FileMode) error
    MkdirAll(path string, perm os.FileMode) error
    Remove(path string) error
    Stat(path string) (os.FileInfo, error)
    Glob(pattern string) ([]string, error)

    // Command execution
    Exec(cmd string, args ...string) ([]byte, error)
    ExecDir(dir, cmd string, args ...string) ([]byte, error)

    // Tmux (for session management)
    TmuxNewSession(name, dir string) error
    TmuxKillSession(name string) error
    TmuxSendKeys(session, keys string) error
    TmuxCapturePane(session string, lines int) (string, error)
}
```

## Implementations

- LocalConnection (gt-f9x.8): Direct file/exec operations
- SSHConnection (future): Operations via SSH

## Usage

```go
func NewRigManager(conn Connection, ...) *RigManager

// Operations work the same regardless of connection type
rm.DiscoverRigs()  // uses conn.Glob, conn.ReadFile
```

## Design Notes

- Connection obtained from MachineRegistry (gt-f9x.9)
- Default is always local
- SSH connection requires machine config (host, key, user)


LocalConnection: Local file/exec/tmux operations

LocalConnection implementation for local machine operations.

## Implementation

```go
type LocalConnection struct {
    tmux *Tmux
}

func NewLocalConnection() *LocalConnection

func (c *LocalConnection) Name() string { return "local" }
func (c *LocalConnection) IsLocal() bool { return true }
```

## File Operations

Direct passthrough to os package:
```go
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.


Machine registry: Store and manage machine configs

Registry for managing remote machines in federation.

## Data Model

```go
type Machine struct {
    Name     string `json:"name"`
    Type     string `json:"type"`      // "local", "ssh", "gcp"
    Host     string `json:"host"`      // for ssh: user@host
    KeyPath  string `json:"key_path"`  // SSH key path
    TownPath string `json:"town_path"` // Path to town on remote
}
```

## Interface

```go
type MachineRegistry struct {
    path     string  // config/federation.json
    machines map[string]*Machine
}

func NewMachineRegistry(configPath string) *MachineRegistry
func (r *MachineRegistry) Get(name string) (*Machine, error)
func (r *MachineRegistry) Add(m *Machine) error
func (r *MachineRegistry) Remove(name string) error
func (r *MachineRegistry) List() []*Machine
func (r *MachineRegistry) Connection(name string) (Connection, error)
```

## Storage

federation.json in config/:
```json
{
  "version": 1,
  "machines": {
    "local": {"type": "local"},
    "gcp-vm-1": {
      "type": "ssh",
      "host": "user@10.0.0.1",
      "key_path": "~/.ssh/gcp_key",
      "town_path": "/home/user/ai"
    }
  }
}
```

## Connection Factory

```go
func (r *MachineRegistry) Connection(name string) (Connection, error) {
    m := r.machines[name]
    switch m.Type {
    case "local":
        return NewLocalConnection(), nil
    case "ssh":
        return NewSSHConnection(m.Host, m.KeyPath), nil
    }
}
```


test pin fix 2


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.

Depends: implement


mol-code-review: Self-improving code review molecule

Create a code review molecule that enables Gas Town to self-improve through automated PR review. Flywheel: review generates quality checks, discovered issues, pattern learning.


Add Gas Town theory of operation to all role primings

All roles (Mayor, Witness, Refinery, Polecat) should get basic GT architecture context: harness, rigs, agents, mail, beads workflow


bd close --continue: auto-advance to next molecule step

Add --continue flag to bd close for seamless molecule step transitions.

## Usage

bd close <step-id> --continue [--no-auto]

## Behavior

1. Closes the specified step
2. Finds next ready step in same molecule (sibling/child)
3. By default, marks it in_progress (--no-auto to skip)
4. Outputs the transition

## Output

[checkmark] Closed gt-abc.3: Implement feature

Next ready in molecule:
  gt-abc.4: Write tests

[arrow] Marked in_progress (use --no-auto to skip)

## If no next step

[checkmark] Closed gt-abc.6: Exit decision

Molecule gt-abc complete! All steps closed.
Consider: bd mol squash gt-abc --summary '...'

## Key behaviors
- Detects parent molecule from closed step
- Finds next unblocked sibling
- Auto-claims by default (propulsion principle)
- Graceful handling when molecule is complete

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


os.Exit() calls in library code prevent proper error handling

internal/cmd/mail.go and other files have os.Exit() calls.

Issues:
- Hard to test
- Prevents graceful shutdown
- Can lose unsaved state
- Doesn't compose well in library code

Should return errors instead of calling os.Exit() directly.
Let main() decide how to exit.

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.


Polecat name pooling: Bounded reusable names

Polecats reuse names from a bounded pool (50) with overflow to sequence numbers.

## Naming Scheme
- Pool: polecat-01 through polecat-50 (prefer low numbers)
- Overflow: <rigname>-<sequenceNumber> (e.g., beads-51, gastown-52)

## Design
- Witness tracks which pool names are in use
- On spawn: pick first available from pool
- If pool exhausted: use rigname-N format
- On completion: pool name returns, sequence numbers don't

## Why?
- User experience: tmux sessions survive polecat restarts
- Users stay attached, see new polecat start (like mayor respawn loop)
- Bounded resource usage for common case
- Scales beyond 50 when needed

## Implementation
- Witness maintains name allocation in beads or local state
- Tmux session runs respawn loop (like mayor)
- Name released on graceful exit or when witness detects dead session

Mayor session cycling prompting

Add session cycling section to Mayor CLAUDE.md template.

## When to Cycle

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

## Composing Handoff Notes

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

2. Compose note with this structure:

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

## Active Swarms
<per-rig swarm status>

## Rig Status
<table of rig health>

## Pending Escalations
<issues needing your decision>

## In-Flight Decisions
<decisions being made>

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

## Delegated Work
<work sent to refineries>

## User Requests
<pending user asks>

## Next Steps
<what next session should do>

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

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

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

Molecule Workflow Engine: Composable Crystallized Workflows

# Epic: Molecule Workflow Engine

**Vision**: Molecules are crystallized, composable, nondeterministic-idempotent workflow templates. Any worker can pick up where any other worker was interrupted and continue along the molecule.

**Christmas Target**: Full molecule-based workflow engine operational by Dec 25, 2025.

## The Core Concepts

1. **Molecule**: Read-only workflow template (beads issue with type=molecule)
2. **Atom/Step**: Individual work unit with prose instructions
3. **Bond**: Dependency between steps
4. **Polymer/Derived**: Molecule composed from other molecules
5. **Instance**: Concrete beads created when molecule is attached to work

## Key Features Needed

### 1. Molecule Composition (Includes Directive)
Molecules can include other molecules:
\`\`\`markdown
## Molecule: gastown-polecat
Includes: mol-engineer-in-box

## Step: install-binary
Build and install the local gt binary.
Needs: submit
\`\`\`

### 2. Standard Molecules
- mol-install-go-binary: Single step to build/install gt
- mol-gastown-polecat: engineer-in-box + install-binary

### 3. Spawn Integration
\`gt spawn --issue <id> --molecule <mol-id>\` creates molecule instance then starts polecat on first ready step.

### 4. Nondeterministic Idempotence
- Steps are atomic (pending → in_progress → completed)
- Any worker can pick up any ready step
- Step timeout/recovery for stuck workers

## Success Criteria
- [ ] Polecats can be spawned with mol-gastown-polecat
- [ ] Derived molecules work end-to-end
- [ ] 10+ polecat swarm completes molecule workflows
- [ ] install-go-binary step runs after successful merges


Molecule composition: Includes directive

Add support for molecule composition via the Includes directive.

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

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

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

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

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


Create mol-install-go-binary molecule

Create a single-step molecule for building and installing the gt binary.

## Molecule Definition
\`\`\`markdown
## Molecule: install-go-binary
Single step to rebuild and install the gt binary after code changes.

## Step: install
Build and install the gt binary locally.

Run from the rig directory:
\`\`\`
go build -o gt ./cmd/gt
go install ./cmd/gt
\`\`\`

Verify the installed binary is updated:
\`\`\`
which gt
gt --version  # if we have version command
\`\`\`
\`\`\`

## Implementation
1. Add to builtin_molecules.go
2. Update SeedBuiltinMolecules to include it
3. Run gt molecule seed

## Acceptance
- [ ] mol-install-go-binary exists in beads
- [ ] Can be instantiated standalone
- [ ] Can be included by other molecules


Create mol-gastown-polecat derived molecule

Create the standard Gas Town polecat workflow molecule.

## Molecule Definition
\`\`\`markdown
## Molecule: gastown-polecat
Full workflow for Gas Town polecats including binary installation.

Includes: mol-engineer-in-box

## Step: install-binary
After merge is submitted, rebuild and install the local gt binary.
This ensures the latest code is available to all local agents.

Run from the rig directory:
\`\`\`
go build -o gt ./cmd/gt
go install ./cmd/gt
\`\`\`

Needs: submit
\`\`\`

## Why This Molecule
Every polecat that pushes to main should also rebuild the binary.
This ensures the installed gt is always current with main.

## Implementation
1. Add to builtin_molecules.go (after Includes support lands)
2. Update SeedBuiltinMolecules
3. Run gt molecule seed

## Acceptance
- [ ] mol-gastown-polecat exists
- [ ] Includes all engineer-in-box steps
- [ ] Adds install-binary step after submit
- [ ] Can be used with gt spawn --molecule


Step recovery: timeout and release

Implement recovery mechanism for stuck molecule steps.

## Problem
When a worker dies mid-step, the step stays in_progress forever.
Need timeout/release mechanism for nondeterministic idempotence.

## Solution
1. Track step start time (claimed_at timestamp)
2. Timeout: After 30 min in_progress, step returns to pending
3. Manual release: bd release <step-id>

## Implementation Options

### Option A: Beads-level timeout
- Add claimed_at field to issues
- bd ready excludes items in_progress < 30 min
- bd ready includes items in_progress > 30 min (auto-recovery)

### Option B: Daemon-level timeout
- Daemon watches in_progress items
- Moves back to pending after timeout

### Option C: Manual only (MVP)
- bd release <id> manually moves in_progress → pending
- Document recovery procedure
- Witness can automate for polecats

## Recommendation
Start with Option C (manual) for Christmas. Add Option A later.

## Acceptance
- [ ] bd release command works
- [ ] Stuck steps can be recovered
- [ ] Documented recovery procedure


Spawn --molecule integration

Implement gt spawn --molecule flag for molecule-based polecat workflows.

Usage: gt spawn --issue gt-xyz --molecule mol-gastown-polecat

Behavior:
1. Validate molecule exists and is well-formed
2. Create molecule instance (child beads) under the issue
3. Find first ready step(s) in the instance
4. Spawn polecat with first ready step as initial work

Implementation:
1. Add --molecule flag to spawn command
2. Call molecule.Instantiate()
3. Query ready steps from instance
4. Pass first ready step to polecat context

Files: internal/cmd/spawn.go

Acceptance:
- --molecule flag works
- Creates proper molecule instance
- Polecat starts on first ready step
- End-to-end test with actual polecat

ZFC Cleanup: Move Go heuristics to Deacon molecule

Remove Go code that makes workflow decisions. All health checking, staleness
detection, nudging, and escalation belongs in the Deacon molecule where Claude
executes it once per minute.

## The Problem

Go code currently implements polling-based health inference:
- Daemon watches heartbeats with hardcoded thresholds
- Decides if agents are "stuck" based on timestamps
- Sends nudges, triggers restarts
- Parses mail subjects with regex to extract intent

This is a ZFC violation. Go should be message transport, not decision-maker.

## The Fix

Move all health/oversight logic to Deacon patrol molecule:
- Deacon runs once per minute
- Claude reads molecule steps, executes them
- Claude decides if agents are stuck (by checking mail, activity, etc.)
- Claude sends nudges/escalations via mail
- Go just routes messages

## Scope

1. daemon/daemon.go - heartbeat staleness logic
2. daemon/backoff.go - exponential backoff decisions
3. daemon/lifecycle.go - regex parsing of lifecycle intent
4. keepalive/keepalive.go - staleness thresholds
5. deacon/heartbeat.go - heartbeat age classification
6. doctor/stale_check.go - staleness detection
7. polecat/manager.go - state derivation from issues

## Success Criteria

- Go code has no hardcoded time.Duration for health decisions
- No regex parsing of mail subjects for intent
- No switch statements deciding agent state
- Deacon molecule has all oversight logic
- Go daemon is just a message router


Remove daemon heartbeat staleness logic

**Files:** daemon/daemon.go (lines 272-325), daemon/backoff.go

**Current behavior:**
- Hardcoded 2min/5min thresholds classify agent health
- Exponential backoff decides nudge intervals
- Go decides "is this agent stuck?" based on timestamps

**Fix:**
- Remove staleness classification from Go
- Remove backoff algorithm
- Daemon becomes pure message router
- Deacon molecule step checks agent health instead

**Lines to remove/refactor:**
- daemon.go:272-274 (staleness thresholds)
- daemon.go:282-295 (poke decision logic)
- daemon.go:317-325 (conditional nudging)
- backoff.go:108-120 (backoff calculations)


Remove keepalive/heartbeat staleness thresholds

**Files:**
- keepalive/keepalive.go (lines 94-111)
- deacon/heartbeat.go (lines 88-108)

**Current behavior:**
- Hardcoded thresholds: 2min=fresh, 5min=stale, 15min=very stale
- Used by daemon to decide whether to poke agents
- Go classifies agent responsiveness

**Fix:**
- Remove all hardcoded time.Duration thresholds
- Keepalive becomes pure timestamp storage
- Deacon molecule step does health assessment:
  "Check if Witness responded in last N minutes" (N from mol config)

**Lines to remove:**
- keepalive.go:96-110 (classification logic)
- heartbeat.go:91-107 (age classification)


Remove doctor staleness detection

**File:** doctor/stale_check.go (lines 11-48)

**Current behavior:**
- DefaultStaleThreshold = 1 hour hardcoded
- Scans molecules for in_progress status older than threshold
- Reports "stale" molecules automatically

**Fix:**
- Remove automatic staleness detection from doctor
- Doctor becomes pure diagnostic tool (reports facts, not judgments)
- Deacon molecule step does "orphan-check" instead:
  "Find issues in_progress with no active polecat"

**Lines to remove:**
- stale_check.go:13 (DefaultStaleThreshold constant)
- stale_check.go:243-256 (staleness classification logic)


Remove polecat state derivation from issue status

**File:** polecat/manager.go (lines 556-599)

**Current behavior:**
- Switch on issue.Status to derive polecat state
- Go decides: open/in_progress → Working, closed → Done

**Fix:**
- Polecat state comes from polecat, not inferred by Go
- Polecat signals state via mail or explicit field
- Or: remove state derivation entirely, just report issue status

**Lines to refactor:**
- manager.go:576-588 (switch statement)

**Priority:** P2 - less critical than daemon/heartbeat logic


Design Deacon molecule health-check step

**Context:** After removing Go heuristics, Deacon molecule needs the logic.

**New molecule step: health-scan**

Claude executes:
1. Check Witness heartbeat: gt witness status <rig>
2. Check Refinery heartbeat: gt refinery status <rig>
3. For each, assess: responsive? stuck? needs restart?
4. If unresponsive for N cycles, send escalation mail

**Key difference from Go approach:**
- Claude makes the judgment call, not hardcoded thresholds
- Claude can read context (what was the agent working on?)
- Claude can ask questions or check additional signals
- Thresholds come from molecule config, not Go constants

**Deliverables:**
- Update mol-deacon-patrol health-scan step
- Add configurable thresholds as molecule variables
- Test with simulated stuck agents


Remove lifecycle intent parsing from Go

daemon/lifecycle.go parses mail subjects with regex looking for restart/shutdown/cycle keywords, then executes actions. Fix: use structured message types in mail body instead of parsing subjects. Go reads action field, does not interpret text.


gt handoff: Unified agent lifecycle command

## Summary

Unified `gt handoff` command for ALL agent types to request lifecycle actions.

## Usage

gt handoff              # Context-aware default
gt handoff --shutdown   # Terminate, cleanup, don't restart
gt handoff --cycle      # Restart with handoff mail
gt handoff --restart    # Fresh restart, no handoff

## Context-Aware Defaults

| Agent Type | Default | Reason |
|------------|---------|--------|
| Polecat | --shutdown | Ephemeral, work is done |
| Witness | --cycle | Long-running, context full |
| Refinery | --cycle | Long-running, context full |
| Mayor | --cycle | Long-running, context full |
| Crew | (sends mail only) | Human-managed |

## What gt handoff Does

1. **Verify safe to stop**
   - Git state clean (no uncommitted changes)
   - Work handed off (PR exists for polecats)

2. **Send handoff mail to self** (for cycle/restart)
   - Captures current state
   - New session will read this

3. **Send lifecycle request to manager**
   - Polecats/Refinery → Witness
   - Witness/Mayor → Daemon
   - Format: mail to <manager> with action type

4. **Set state: requesting_<action>**
   - Lifecycle manager checks this before acting

5. **Wait for termination**
   - Don't self-exit - let manager kill session
   - Ensures clean handoff

## Lifecycle Request Flow

Agent                           Lifecycle Manager
  |                                    |
  | 1. gt handoff --cycle              |
  |    a. Verify git clean             |
  |    b. Send handoff mail to self    |
  |    c. Set requesting_cycle=true    |
  |    d. Send lifecycle request       |
  |------------------------------------→|
  |                                    |
  |                   2. Receive request
  |                   3. Verify state  |
  |                   4. Kill session  |
  |                   5. Start new     |
  |                      (for cycle)   |
  |                                    |
  |         New session reads handoff  |
  |         Resumes work               |

## Who Manages Whom

| Agent | Sends lifecycle request to |
|-------|---------------------------|
| Polecat | <rig>/witness |
| Refinery | <rig>/witness |
| Witness | daemon/ |
| Mayor | daemon/ |

## Implementation

1. Detect current role (polecat, witness, refinery, mayor, crew)
2. Apply context-aware default if no flag specified
3. Run pre-flight checks (git clean, work handed off)
4. Send handoff mail to self (if cycling)
5. Send lifecycle request to appropriate manager
6. Set requesting_<action> in state.json
7. Wait (manager will kill us)

## For Polecats (--shutdown)

Additional cleanup after kill:
- Witness removes worktree
- Witness deletes polecat branch
- Polecat ceases to exist

## Related Issues

- gt-99m: Daemon (handles Mayor/Witness lifecycle)
- gt-7ik: Ephemeral polecats (polecat cleanup)
- gt-eu9: Witness session cycling

Clarify Mayor vs Witness cleanup responsibilities

Document the cleanup authority model: Witness owns ALL per-worker cleanup, Mayor never involved.

## The Rule

**Witness handles ALL per-worker cleanup. Mayor is never involved.**

## Why This Matters

1. Separation of concerns: Mayor strategic, Witness operational
2. Reduced coordination overhead: No back-and-forth for routine cleanup
3. Faster shutdown: Witness kills workers immediately upon verification
4. Cleaner escalation: Mayor only hears about problems

## What Witness Handles

- Verifying worker git state before kill
- Nudging workers to fix dirty state
- Killing worker sessions
- Updating worker state (sleep/wake)
- Logging verification results

## What Mayor Handles

- Receiving swarm complete notifications
- Deciding whether to start new swarms
- Handling escalations (stuck workers after 3 retries)
- Cross-rig coordination

## Escalation Path

Worker stuck -> Witness nudges (up to 3x) -> Witness escalates to Mayor -> Mayor decides: force kill, reassign, or human

## Anti-Patterns

DO NOT: Mayor asks Witness if worker X is clean
DO: Witness reports swarm complete, all workers verified

DO NOT: Mayor kills worker sessions directly
DO: Mayor tells Witness to abort swarm, Witness handles cleanup

DO NOT: Workers report done to Mayor
DO: Workers report to Witness, Witness aggregates and reports up


gt spawn: polecats report success but no work actually happens

## Problem

gt spawn polecats have multiple silent failure modes:

### Failure Mode 1: No gt prime
- Claude starts at prompt and waits for input
- SessionStart hook doesn't auto-run 'gt prime'
- Without gt prime, polecats don't pick up work

### Failure Mode 2: No git push (CRITICAL)
- Polecat commits code locally
- Polecat closes the beads issue
- Polecat sends POLECAT_DONE
- **But code is never pushed to remote branch**
- When worktree is cleaned up, commits are lost forever
- Issue appears closed but no code exists

## Evidence

testcat on bd-d28c:
- Reported 'Work Complete' with commits 7d3447b9, cd87e541
- Closed bd-d28c
- Submitted MR bd-yx22
- But: `grep -r 'TestCreateTombstone' cmd/bd/*.go` returns nothing
- No polecat/testcat branch on remote

## Required Fixes

1. Polecats MUST push their branch before closing issues
2. Witness MUST verify branch exists on remote before cleanup
3. gt spawn should auto-nudge 'gt prime'
4. Consider: Polecat handoff should fail if unpushed commits exist

## Verification Protocol for Witness

Before accepting POLECAT_DONE:
```bash
# 1. Verify branch pushed
git branch -r | grep polecat/<name>

# 2. Verify code exists
grep -r '<expected_function>' path/to/files

# 3. Only then cleanup
```

Fixed: Added BranchPushedToRemote() check to verifyPolecatState - witness now verifies branches are pushed before cleanup


Digest: mol-deacon-patrol

Patrol: 4 msgs (2 blocked on bd mol current, 2 handoffs). 11 polecats, 18 sessions. Swarm in progress.


Refinery needs branch visibility: Convert to worktree or push branches

The refinery can't see polecat branches because it's a separate clone, not a worktree.

## Problem
- Polecats are worktrees of mayor/rig (correct, per gt-4u5z)
- Refinery is still a separate clone at refinery/rig (not converted)
- Polecat branches are local to mayor/rig, invisible to refinery

## Current Workaround
Push polecat branch to origin before gt done.

## Options
1. Convert refinery to worktree of mayor/rig (preferred - matches gt-4u5z design)
2. Have gt done push the branch before creating MR
3. Have refinery fetch from mayor/rig directly

## Evidence
Tracer bullet 2025-12-23: Refinery couldn't see polecat/tracer until we pushed it to origin.


Witness cleanup should know worktree parent repo

Witness had to discover that polecat worktrees are created from mayor/rig, not the rig root.

## Problem
When cleaning up polecat/tracer:
- Witness ran git worktree remove from gastown/ - failed
- Had to discover worktree was from mayor/rig
- Then removed correctly

## Improvement
Witness should know the worktree parent repo path (mayor/rig) and clean up from there directly.

## Evidence
Tracer bullet 2025-12-23: Witness took extra steps to figure out cleanup path.


Integration test: agent waits for CI via gate

End-to-end test of the gate workflow.

## Test Scenario
1. Agent creates gate: bd gate create --await gh:run:123 --timeout 5m --notify beads/dave
2. Agent writes handoff and exits
3. Deacon patrol checks gate condition
4. (Mock) GitHub run completes
5. Deacon notifies waiter and closes gate
6. New agent session reads mail and resumes

## Test Requirements
- Mock GitHub API responses
- Test timeout path
- Test multiple waiters
- Verify mail notifications sent

## Moved from beads
Originally bd-rl5t. Tests Deacon patrol which is in gastown.


Add keyboard navigation and filtering

Keyboard navigation: j/k or arrows to move, enter to expand/collapse, q to quit. Filtering: by rig name, worker name, event type. Search within activity stream.


Witness patrol: Add banners and wisp-based execution

Bring Witness patrol up to Deacon's level of sophistication:

## Current state
- mol-witness-patrol exists (gt-qflq)
- Basic step definitions

## Needed
1. **Banners** - Print step banners like Deacon does:
   ```
   ═══════════════════════════════════════════════════════════════
     👁 POLECAT-SCAN
     Checking polecat health and nudging stale workers
   ═══════════════════════════════════════════════════════════════
   ```

2. **Wisp-based execution** - Spawn patrol as wisp, squash when complete
3. **Handoff bead attachment** - Witness needs its own handoff bead with attached_molecule
4. **Loop-or-exit step** - Context-aware cycling like Deacon
5. **Patrol summary banner** at end of each cycle

## Reference
See Deacon patrol implementation in ~/gt/deacon/CLAUDE.md

Implemented in witness.md.tmpl: banners, wisp-based execution, handoff bead attachment, loop-or-exit, patrol summary


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.


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

## Related

- gt-rana: Patrol System

Merge Queue in Beads: Universal chit system for all work

**Design doc**: docs/merge-queue-design.md


MR field parsing: extract structured fields from description

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

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

Reference: docs/merge-queue-design.md#merge-request-schema


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

Reference: docs/merge-queue-design.md#conflict-resolution-strategies


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


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


MQ dashboard widget: queue status in TUI

Add merge queue status widget to the Bubbletea TUI dashboard.

Display:
┌─────────────────────────────────────────────────┐
│              MERGE QUEUE STATUS                  │
├─────────────────────────────────────────────────┤

Direct landing integration: gt land uses MR or bypasses

Integrate direct landing with merge queue.

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

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

This ensures direct landing still creates proper records.

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


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


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

Reference: docs/merge-queue-design.md#id-convention


MR state transitions: validate open→in_progress→closed

Enforce valid state transitions for merge-requests:

Valid transitions:
- open → in_progress (Engineer claims MR)
- in_progress → closed (merge success or rejection)
- in_progress → open (failure, reassign to worker)
- open → closed (manual rejection)

Invalid:
- closed → anything (immutable once closed)

Implement validation in MR update operations.

Reference: docs/merge-queue-design.md#state-machine


gt mq integration create: create integration branch for epic

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

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

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

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

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


gt mq integration land: merge integration branch to main

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

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

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

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

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


gt mq integration status: show integration branch status

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

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

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

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

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

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


Auto-target: MRs for epic children target integration branch

Automatically target integration branches for epic children.

When 'gt mq submit' is called:
1. Parse source issue from branch
2. Check if issue has a parent epic
3. Check if integration/<epic> branch exists
4. If yes: set target=integration/<epic>
5. If no: set target=main

This ensures batch work automatically flows to integration branches.

Also update 'gt mq submit --epic' to explicitly target an epic's integration branch.

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


MQ config schema: merge_queue section in rig config.json

Define and implement merge_queue configuration in rig config.

Schema:
{
  "merge_queue": {
    "enabled": true,
    "target_branch": "main",
    "integration_branches": true,
    "on_conflict": "assign_back",  // or "auto_rebase"
    "run_tests": true,
    "test_command": "go test ./...",
    "delete_merged_branches": true,
    "retry_flaky_tests": 1,
    "poll_interval": "30s",
    "max_concurrent": 1
  }
}

Implement:
- Config loading in rig package
- Default values
- Validation

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


Per-epic config overrides: custom merge settings

Allow per-epic merge configuration overrides.

Epic can specify merge_config in its description:
  merge_config:
    run_tests: true
    test_command: 'go test -race ./...'
    on_conflict: assign_back

When processing MRs for an epic:
1. Load rig-level merge_queue config
2. Check if epic has merge_config
3. Merge epic config over rig config
4. Use merged config for processing

Use cases:
- Risky refactors: more thorough testing
- Urgent fixes: skip some checks
- Experimental work: different test suite

Reference: docs/merge-queue-design.md#per-epic-overrides


Pinned beads architecture implementation

Implement the pinned beads architecture from docs/pinned-beads-design.md

Phases:
1. Doctor checks for hook validation
2. Dashboard visibility (gt hooks, gt dashboard)
3. Protocol enforcement (self-pin, audit trail)
4. Documentation updates

Completed and merged to main in gt-h6eq swarm


Add hook-singleton doctor check

Add gt doctor check to ensure each agent has at most one handoff bead.

Check: hook-singleton
Error if: Multiple pinned beads with same '{role} Handoff' title
Fix suggestion: Delete duplicate(s) with bd close


Add hook-attachment-valid doctor check

Add gt doctor check to verify attached molecules exist and are not closed.

Check: hook-attachment-valid
Error if: Hook's attached_molecule field points to non-existent or closed issue
Fix suggestion: Clear attachment with gt mol detach


Add orphaned-attachments doctor check

Add gt doctor check for molecules attached to non-existent agents.

Check: orphaned-attachments
Warning if: Handoff bead exists for agent that no longer has worktree
Fix suggestion: Re-sling to active agent or close molecule


Add stale-attachments doctor check

Add gt doctor check for work stale on hook without progress.

Check: stale-attachments
Warning if: Attached molecule has no activity for >24h
Suggestion: Check agent status, consider nudge or reassignment


Implement gt hooks command

New command to show all hooks across a rig.

Usage: gt hooks [rig]

Output shows:
- All polecats and their hook status
- Witness hook status
- Refinery hook status
- Crew member hook status
- Progress bars for attached molecules

Implemented gt hooks command with progress bars and JSON output


Add hook status to gt status output

Enhance gt status to show hook summary for each rig.

Current: Shows rig list and basic counts
New: Also shows occupied hooks count and any stale attachments

Implemented: added HookInfo struct, hook discovery, and output to gt status


Implement gt mol attach-from-mail command

Allow agents to self-pin work from mail.

Usage: gt mol attach-from-mail <mail-id>

Behavior:
1. Read mail body for attached_molecule field
2. Attach molecule to agent's hook
3. Mark mail as read
4. Return control for execution

Handles case where work was sent via mail but not slung to hook.


Add audit trail for hook detach operations

Log detachment events for debugging and monitoring.

When work is detached from hook:
- Log timestamp, agent, molecule ID, reason
- If abnormal (not completion), notify Witness
- Consider adding to wisp digest for patrol cycles


Update role prompts with hook protocol

Update role prompt templates to include hook-first protocol.

Templates to update:
- polecat.md.tmpl
- deacon.md.tmpl
- witness.md.tmpl
- refinery.md.tmpl
- crew.md.tmpl

Each should include:
1. Check hook first (gt mol status)
2. If empty, check mail for attached work
3. Self-pin protocol if needed


session-gc

Clean dead sessions. Run gt gc --sessions.


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 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.

## Related
- gt-c92: CLI: all command for batch polecat operations


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.


Mail system: message types and threading

GGT mail system needs message types and threading like PGT.

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

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

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

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

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

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

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

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

Remove pinned field workaround after beads fix

## Summary

Once bd-phtv is fixed in beads, we can remove the workaround documentation and potentially simplify the pinToHook() implementation.

## Current Workaround

The handoff bead attachment mechanism (AttachMolecule) is used as the primary work assignment mechanism instead of the pinned field. This works correctly but adds complexity.

## Changes After Beads Fix

1. Remove the NOTE comment in internal/beads/beads.go:Pin() explaining the bug
2. Consider simplifying pinToHook() if the pinned field becomes reliable
3. Update gt-o3is to reference the fix

## Blocked By

This issue is blocked by external:beads:pinned-field-fix (bd-phtv).
When that capability is shipped, this issue becomes ready.

## Related

Heartbeat convention: simple liveness signal for agents

Lightweight liveness signal extracted from Deacon epic (gt-5af).

**Implementation**: Each agent writes a timestamp file on activity:
```bash
echo '{"ts":"'$(date -Iseconds)'"}' > ~/gt/<role>/heartbeat.json
```

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

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

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


GGT Command Parity: Complete gt command coverage

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

- Session health checks
- Nudging stuck agents


Update deacon.md.tmpl with correct molecule commands

The deacon prompt references commands that don't exist:
- gt mol bond → should be bd mol run or gt mol arm
- gt mol status → needs gt mol command tree first

Update after gt mol command tree is implemented.

Depends on: gt mol command tree issue

Updated deacon.md with correct commands: gt mol status, bd mol spawn, gt mol squash


Update templates for Propulsion Principle

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

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

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

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

All four templates updated with Propulsion Principle


mol-polecat-work

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


Deacon session cycling: first step of rounds

First step of every Deacon wake cycle: check if a fresh session is needed.

## Why First

Token costs are quadratic with session length. A Deacon running for hours
accumulates massive context. Better to cycle early and often.

## Implementation

At wake, before doing anything else:

1. Check context budget estimate (conversation turns, tool calls, etc.)
2. If budget is low (e.g., >50% consumed), request cycle:
   - Write handoff mail to self with current state
   - Request lifecycle: cycle via daemon
   - Daemon kills session, starts fresh
   - New session reads handoff mail, continues

## Decision Criteria

- Conversation turns > N (configurable, default 50?)
- Explicit "context feels heavy" signal from Claude
- Time since last cycle > M hours (configurable, default 4?)
- Forced cycle on certain events (e.g., major config change)

## State to Preserve in Handoff

- Current health status
- Pending lifecycle requests (in flight)
- Plugin state (last run times, outcomes)
- Any active timers

## Relation to Daemon

The Deacon requests its own cycle via the same lifecycle mechanism:
```
gt mail send deacon/ -s "LIFECYCLE: deacon/ requesting cycle" -m "..."
```

Daemon sees this, kills gt-deacon session, respawn loop restarts it.


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.


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
```


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.


Deacon plugin scheduler: cron-like execution

Implement scheduled plugin execution in the Deacon's plugins step.

## Concept

Plugins are just directories with config. Deacon checks which are due
and executes them during the plugins step of rounds.

## Plugin Registration

Plugins are registered in:
1. Pinned kernel bead (preferred)
2. `{townRoot}/plugins/` directory scan (fallback)

Each plugin has:
```json
{
  "name": "beads-hygiene",
  "schedule": "0 2 * * *",
  "last_run": "2025-12-20T02:00:00Z",
  "enabled": true,
  "attention_budget": "low",
  "max_duration_minutes": 30
}
```

## Schedule Format

Standard cron format: `minute hour day month weekday`
- `0 2 * * *` - 2 AM daily
- `0 4 * * 0` - 4 AM Sundays
- `*/15 * * * *` - Every 15 minutes

## Execution

During plugins step:
1. Load plugin schedules from kernel bead + directory
2. For each plugin:
   a. Parse schedule, check if due (last_run + schedule)
   b. If due, execute:
      - Read `plugins/{name}/CLAUDE.md` for context
      - Run plugin logic (inline or spawn subagent)
      - Record outcome and update last_run
3. Continue to next step

## Plugin Execution Modes

- **inline**: Deacon runs the plugin logic directly (simple, fast)
- **subagent**: Spawn a polecat-like agent for the plugin (complex, parallel)
- **mail**: Send mail to another agent to do the work (delegation)

## State Tracking

`{townRoot}/deacon/plugin-state.json`:
```json
{
  "plugins": {
    "beads-hygiene": {
      "last_run": "2025-12-20T02:00:00Z",
      "last_outcome": "success",
      "run_count": 42,
      "failure_count": 2
    }
  }
}
```

## Relation to gt-axz

This implements the execution side of the plugin architecture (gt-axz).
gt-axz defines the format; this task implements the scheduler.


Deacon event/timer callbacks: reactive triggers

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

## Timer Callbacks

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

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

## Event Subscriptions

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

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

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

## Event Sources

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

## Event Types

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

## Event Processing

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

## Relation to Mail

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


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.

mol-deacon-patrol

[RESURRECTED] This issue was deleted but recreated as a tombstone to preserve hierarchical structure.

Original description:
Deacon patrol molecule template. Label: template


inbox-check

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


loop-or-exit

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


Fix blocking bugs (gt-dsfi, gt-n7z7, gm-c6b)

Fix bugs blocking Witness functionality:

1. gt-dsfi: handoff deadlock
   - Polecats hang when trying to exit
   - Blocks shutdown request handler

2. gt-n7z7: refinery foreground race condition
   - Sometimes detects parent as already running
   - Blocks reliable Refinery startup

3. gm-c6b: mail coordination
   - Cross-rig mail should use town-level database
   - Affects Witness <-> Mayor communication

These should be fixed early as they'll block integration testing.

Fixed gt-dsfi and gt-n7z7. Issue gm-c6b not found in database.


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.

## 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

    └── 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


Polecat Lifecycle Events: Refinery-Witness Coordination

## Problem

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

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

## Solution: Two-Event Lifecycle

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

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

## Village Sibling Watch

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

## Recovery

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


Refinery: Add lifecycle-notify step to patrol

After successful merge in handleSuccess(), send lifecycle notification to Witness.

## Implementation

1. Add new mail type: `LIFECYCLE: work merged`
2. In engineer.go handleSuccess(), after closing MR and source issue:
   ```
   gt mail send <rig>/witness -s "LIFECYCLE: work merged" -m "
   Worker: <polecat>
   MR: <mr-id>
   Issue: <source-issue>
   Commit: <merge-commit>
   Action: Polecat work merged. Worktree eligible for recycling.
   "
   ```

3. Update mol-refinery-patrol to include lifecycle-notify step between merge-push and loop-check

## Acceptance
- Successful merges send mail to Witness
- Mail includes worker name, MR id, source issue, commit SHA


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)


MQ Submit: Notify Witness on MR submission

When `gt mq submit` is run, notify the Witness so it can verify the submission.

## Implementation

1. In mq_submit.go after successful MR creation:
   ```
   gt mail send <rig>/witness -s "LIFECYCLE: mr submitted" -m "
   Worker: <polecat>
   MR: <mr-id>
   Branch: <branch-name>
   Target: <target-branch>
   Action: Verify MR submission, help polecat if needed.
   "
   ```

2. This happens BEFORE the existing polecat auto-cleanup logic

## Acceptance
- MR submission sends notification to Witness
- Witness receives mail with all relevant details
- Works for both polecat and crew submissions


Witness: Verify MR submission on notification

When Witness receives `LIFECYCLE: mr submitted`, verify the submission was clean.

## Implementation

1. Add handler for "LIFECYCLE: mr submitted" mail
2. Check MR status: `gt mq status <mr-id>`
3. If MR looks good (status=open, no errors): log success, allow polecat to idle
4. If MR has issues:
   - Check polecat git state
   - Nudge polecat to fix if session still alive
   - Log issue for monitoring

## Acceptance
- Witness verifies MR after submission notification
- Can detect problematic submissions
- Provides early intervention opportunity


Polecat state tracking: Add mr_submitted and merged states

Track polecat lifecycle state separate from session state.

## New States

| State | Meaning |
|-------|---------|
| active | Working on assigned issue |
| mr_submitted | MR submitted, waiting for merge |
| idle | No current work, session may be alive |
| merged | Work successfully merged by Refinery |
| retired | Session killed, worktree removed |

## Implementation

1. Add state field to polecat tracking (state.json or beads)
2. `gt polecat update <name> --state=<state>`
3. `gt polecat list` shows state column
4. State transitions:
   - active → mr_submitted (on gt mq submit)
   - mr_submitted → merged (on Refinery notification)
   - merged → retired (on worktree cleanup)

## Acceptance
- Polecat state tracked and queryable
- State transitions happen at correct lifecycle points
- `gt polecat list` shows current state


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)


Witness patrol: Add sibling-check for Refinery

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

## Implementation

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

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


Recovery: Detect orphaned merged polecats

Safety net for when Refinery misses sending lifecycle notification.

## Detection Points

**Witness polecat-scan**:
- For each polecat in `mr_submitted` state:
  - Check MR status: `gt mq status <mr-id>`
  - If MR is closed/merged but polecat state is still mr_submitted:
    - Update polecat state to `merged`
    - Log recovery action

**Deacon orphan-check**:
- Query all closed MRs
- Cross-reference with polecat states
- If merged MR but polecat not in merged/retired state:
  - Send correction to Witness
  - Log for metrics (indicates Refinery notification missed)

## Acceptance
- Orphaned polecats detected and corrected
- Recovery is logged for monitoring
- No work lost due to missed notifications


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

Depends on Beads: bd-zmmy (bd ready resolution)


gt sling: nudge crew/mayor if session is running

When slinging to crew or mayor, if they have an active tmux session, send a nudge notification so they know work has landed on their hook.

Currently only slingToPolecat nudges (lines 514-521 in internal/cmd/sling.go).

Missing nudge in:
- slingToCrew (line ~669)
- slingToMayor (line ~876)

NOT applicable to patrol-based agents (witness, refinery, deacon) - they run on cycles and pick up work via hook check, not interactive nudge.

Implementation:
1. For crew: need to determine session name (e.g., gastown-crew-max)
2. Check if session running via tmux
3. If running, call t.NudgeSession() with appropriate message


Molecular Chemistry Cleanup: Fix inaccurate molecule depictions

## The Correct Model

According to molecular-chemistry.md, the hierarchy is:

Formula (YAML DSL) --cook--> Proto (template beads) --pour/wisp--> Mol/Wisp (actual work)

- **Formulas**: YAML files in .beads/formulas/ that define workflow structure
- **Cook**: Transform formula to proto beads (with [template] label)
- **Proto**: Template beads with child beads for each step
- **Pour**: Proto to Mol (persistent liquid)
- **Wisp**: Proto to Wisp (ephemeral vapor)

## What's Wrong

We have legacy code and docs that use the OLD model where molecules are defined
in Go code as structs with embedded markdown, instead of as formula YAML cooked into proto beads.

---

## MAJOR ISSUES

### 1. Go Code: molecules_*.go (DELETE OR REWRITE)

**Files:**
- internal/beads/builtin_molecules.go
- internal/beads/molecules_patrol.go (19KB!)
- internal/beads/molecules_session.go (13KB)
- internal/beads/molecules_work.go (13KB)

**Problem:** Defines molecules as Go structs with embedded markdown descriptions.
This is completely wrong. Molecules should come from:
1. Formula YAML files cooked into proto beads
2. Proto beads with child beads for each step

**Used by:**
- install.go:seedBuiltinMolecules() - seeds during install
- catalog.go - includes in catalog
- molecule_list.go:ExportBuiltinMolecules()

**Fix:** Delete these files. Create formula YAML files instead. Update seeding
to cook formulas into protos.

### 2. Role Templates: Steps Listed in Markdown (REWRITE)

**Files:**
- prompts/roles/deacon.md - Lists 7 patrol steps
- prompts/roles/refinery.md - Lists 10 patrol steps
- prompts/roles/witness.md - Procedural "Heartbeat Protocol" (not molecule-based!)
- prompts/roles/polecat.md - References molecule steps

**Problem:** The steps are listed in the markdown template, but they should be
discovered from the proto beads via bd mol current. Templates should say
"check your hook, run your patrol" without duplicating step definitions.

**Fix:** Templates should describe HOW to run a patrol (propulsion principle,
bd mol current, bd close --continue), not WHAT the steps are.

### 3. Protos are Empty/Missing (CREATE)

**Current state:**
- gt-iep9 (mol-deacon-patrol) - Only 2 child steps
- gt-qflq (mol-witness-patrol) - EMPTY (0 children)
- mol-refinery-patrol - DOESN'T EXIST

**Fix:** Create formula YAML files for each patrol, cook them into proper protos
with child beads for each step.

---

## MEDIUM ISSUES

### 4. Command Confusion: spawn vs pour/wisp

**Files:**
- prompts/roles/deacon.md - Uses bd mol spawn ... --assignee=deacon
- prompts/roles/refinery.md - Uses bd mol spawn ... --wisp
- Various docs

**Problem:** The correct commands per molecular-chemistry.md:
- bd pour proto - Create persistent mol (liquid)
- bd wisp proto - Create ephemeral wisp (vapor)
- bd mol spawn - Old/deprecated

**Fix:** Update all references to use bd wisp for patrols, bd pour for
persistent work.

### 5. Command Confusion: gt mol vs bd mol

**Files:** Various docs and templates

**Problem:** Some use gt mol status, others bd mol status. Need to clarify:
- gt mol = Gas Town wrapper (if it exists, what does it add?)
- bd mol = Beads molecule commands (authoritative)

**Fix:** Audit and standardize. If gt mol is a thin wrapper, remove it.

### 6. polecat-wisp-architecture.md (UPDATE OR DELETE)

**File:** docs/polecat-wisp-architecture.md

**Problem:** References adding molecules to builtin_molecules.go - old model.

### 7. manager.go (UPDATE)

**File:** internal/rig/manager.go

**Problem:** Comment references "subset of builtin_molecules.go for seeding"

---

## IMPLEMENTATION ORDER

1. **Create formula YAML files** for the 3 patrol molecules:
   - mol-deacon-patrol.formula.yaml
   - mol-witness-patrol.formula.yaml
   - mol-refinery-patrol.formula.yaml

2. **Implement bd cook** if not already working to create protos from formulas

3. **Cook the formulas** into proto beads with proper child beads

4. **Update role templates** to use propulsion principle without step lists

5. **Delete molecules_*.go** once formulas are working

6. **Update install.go** to cook formulas instead of seeding Go structs

7. **Audit gt mol vs bd mol** and standardize


Create patrol formula YAML files

Create formula YAML files for:
- mol-deacon-patrol.formula.yaml
- mol-witness-patrol.formula.yaml
- mol-refinery-patrol.formula.yaml

Use the step definitions currently in molecules_patrol.go as reference.
Store in .beads/formulas/

Created 4 patrol formula YAML files in .beads/formulas/


Cook patrol formulas into proto beads

Use bd cook to transform formula YAML into proto beads with proper child beads for each step.

Verify with bd mol show that protos have all children.


Delete molecules_*.go files

Remove legacy Go-defined molecules:
- internal/beads/builtin_molecules.go
- internal/beads/molecules_patrol.go
- internal/beads/molecules_session.go
- internal/beads/molecules_work.go

Update install.go to cook formulas instead of seeding Go structs.
Update catalog.go if needed.


Rewrite role templates without step lists

Update:
- prompts/roles/deacon.md
- prompts/roles/refinery.md
- prompts/roles/witness.md

Templates should describe HOW to run patrols (propulsion principle, bd mol current, bd close --continue) not WHAT the steps are. Steps come from proto beads.


Standardize bd mol vs gt mol commands

Audit all docs and templates for command usage.

Clarify:
- gt mol = Gas Town wrapper (what does it add?)
- bd mol = Beads molecule commands (authoritative)

If gt mol is thin wrapper, consider removing.


Remove spawn - use pour/wisp only (see bd-8y9t)

Remove bd mol spawn entirely from vocabulary.

Replace all references with:
- bd pour <proto> - Create persistent mol (liquid)
- bd wisp <proto> - Create ephemeral wisp (vapor)

'spawn' doesn't fit the chemistry metaphor. Two phase transitions (pour/wisp) are clearer than one command with flags.

See bd-XXX for Beads-side removal.

Implement mol bond command for dynamic child molecules

Add 'gt mol bond' command that creates child molecules at runtime with variable substitution.

Usage from mol-witness-patrol survey-workers step:
```bash
bd mol bond mol-polecat-arm $PATROL_WISP_ID \
  --ref arm-$polecat \
  --var polecat_name=$polecat \
  --var rig=<rig>
```

This creates child wisps like patrol-x7k.arm-ace with variables expanded.

Implementation:
1. Add 'bond' subcommand to mol command
2. Accept: proto ID, parent ID, --ref for child suffix, --var key=value pairs
3. Call InstantiateMolecule with Context map populated from --var flags
4. Return created child ID

Critical for Christmas Ornament pattern - without this, Witness cannot spawn per-polecat inspection arms.

Implemented mol bond command for dynamic child molecule creation

Polecat doesn't auto-start after spawn inject - requires manual nudge

## Problem

After `gt spawn --issue <id> --create`, the polecat session shows Claude Code started with the injected prompt, but Claude doesn't begin processing. The prompt just sits there until manually nudged.

## Evidence

```
$ gt spawn --issue gt-rixa --rig gastown --create
...
✓ Session started. Attach with: gt session at gastown/furiosa
  Polecat nudged to start working
  Witness notified to monitor startup
```

Session shows:
```
> You have a work assignment. Run 'gt mail inbox' to see it, then start
  working on issue gt-rixa.

  ⏵⏵ bypass permissions on (shift+tab to cycle)
```

But Claude doesn't respond. Manual nudge required:
```
$ gt nudge gt-gastown-furiosa "Please start working..."
```

After nudge, polecat immediately starts working correctly.

## Hypothesis

The spawn inject happens before Claude Code is fully initialized. The text arrives in the input buffer, but Claude hasn't started listening yet. By the time Claude starts, the input has already been 'consumed' as initial prompt text but not submitted.

## Resolution Plan

This will be solved by the **polecat molecule workflow** (mol-polecat-work), which provides structured lifecycle management. The molecule approach handles startup, work, and shutdown as discrete steps with proper state tracking.

**Blocked on**: beads/crew/dave completing ephemeral molecules (bd mol bond, ephemeral beads repo).

## Workaround

For now, use `gt nudge` if a polecat doesn't start within ~30 seconds of spawn.

Work assignment messages should auto-close on completion

When a polecat completes work on an issue, the work assignment message (msg-type:task) stays open. Found 7 stale work assignments in gastown after swarm completed.

Proposal: When bd close is called on an issue, auto-close any work assignment messages that reference that issue in their body.

Alternative: Work assignment messages could use a different lifecycle - perhaps they should be acked (closed) when the polecat starts working, not when they finish.
