bd: Add town-level activity signal in PersistentPreRun

Add activity signaling to beads so daemon can detect bd usage.

In cmd/bd/main.go PersistentPreRun, add a call to write activity to
the Gas Town daemon directory if running inside a Gas Town workspace.

The signal file is ~/gt/daemon/activity.json (or detected town root).

Format:
{
  "last_command": "bd create ...",
  "actor": "gastown/crew/max",
  "timestamp": "2025-12-26T19:30:00Z"
}

Should be best-effort (silent failure) to avoid breaking bd outside Gas Town.

Document bd mol bond/squash/burn CLI

Create CLI reference documentation for molecule commands:

## bd mol bond

Instantiate a proto into a runnable molecule.

```bash
bd mol bond <proto-id> [--wisp] [--assignee=<addr>]
```

- Default: creates a Mol (durable, in main beads)
- --wisp: creates a Wisp (ephemeral, in .beads-ephemeral/)
- --assignee: who will execute this molecule

## bd mol squash

Complete a molecule and generate digest.

```bash
bd mol squash <mol-id> --summary='...'
```

- For Mol: creates digest in git history
- For Wisp: evaporates (no permanent record)
- --summary: required summary of what was accomplished

## bd mol burn

Abandon a molecule without completing.

```bash
bd mol burn <mol-id> [--reason='...']
```

- Discards molecule state
- No digest created
- Use when molecule is no longer needed

Molecules: Composable Workflow Beads

## Summary

Molecules are crystallized workflow patterns stored as Beads issues.
When instantiated, the molecule creates child beads forming a DAG.

## Key Insight: Molecules ARE Beads

Per HOP Decision 001: Beads IS the ledger. Molecules don't get a separate YAML format - they're issues with `type: molecule` containing prose-based step definitions.

Agents don't need rigid schemas. They parse natural language natively. A molecule is just instructions with enough structure for tooling.

## Example: Engineer in a Box

```markdown
id: mol-xyz
type: molecule
title: Engineer in a Box

This workflow takes a task from design to merge.

## Step: design
Think carefully about architecture. Consider existing patterns,
trade-offs, testability.

## Step: implement
Write clean code. Follow codebase conventions.
Needs: design

## Step: review
Review for bugs, edge cases, style issues.
Needs: implement

## Step: test
Write and run tests. Cover happy path and edge cases.
Needs: implement

## Step: submit
Submit for merge via refinery.
Needs: review, test
```

## Instantiation

```bash
# Attach molecule when spawning
gt spawn --issue gt-abc --molecule mol-xyz

# Creates child beads atomically:
gt-abc.design     ← ready first
gt-abc.implement  ← blocked by design
gt-abc.review     ← blocked by implement
gt-abc.test       ← blocked by implement
gt-abc.submit     ← blocked by review, test
```

Each step issue gets an `instantiated-from` edge to the molecule (with step metadata).

## Why This Matters

1. **Unified data plane**: Everything in Beads, no parallel YAML channel
2. **AI-native**: Prose instructions, not rigid schemas
3. **Error isolation**: Each step is a checkpoint - failure doesn't lose progress
4. **Scales with AI**: As agents get smarter, they handle more complex molecules

## Implementation Primitives

- `ParseMoleculeSteps()`: Extract steps from prose (convention-based)
- `InstantiateMolecule()`: Atomic transaction creating all steps + edges
- `instantiated-from` edge type: Track provenance
- Parameterization: `{{variable}}` substitution from context map

Missing space in error messages (handoff.go, prime.go)

Minor typo in error messages at two locations:

**handoff.go L895**:
```go
fmt.Println(style.Dim.Render("Run manually: bd --no-daemon wisp" + protoID))
// Missing space before protoID
```

**prime.go L1061**:
Same issue.

**Fix**: Add space before protoID:
```go
fmt.Println(style.Dim.Render("Run manually: bd --no-daemon wisp " + protoID))
```


Layered context onboarding pattern

Pattern from handoff discussion:

## Pattern: Layered Context Onboarding

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

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

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

## Recommendation

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


gt sling fails for terminated polecats even with --naked flag

## Problem
When a polecat terminates after completing work (submits MR, session ends), the polecat directory still exists but the tmux session is gone. Attempting to sling new work to that polecat fails:

```
gt sling bd-fa1q beads/Toast --naked
Error: resolving target: getting pane for gt-beads-toast: exit status 1
```

The `--naked` flag should bypass tmux pane requirements, but the error occurs during target resolution before the flag is checked.

## Expected Behavior
`gt sling <bead> <polecat> --naked` should:
1. Attach work to the polecat hook
2. Skip session creation (manual start later)
3. NOT require an existing tmux pane

## Workaround
Use crew workers instead (they have persistent sessions).

## Fix
Target resolution should check `--naked` flag before attempting pane lookup, or provide a way to respawn terminated polecats.

Patrol 14


Deacon patrol wisps should use town beads, not gastown rig beads

## Problem

The deacon is a town-level role but stores patrol wisps in gastown/mayor/rig/.beads/ (see internal/cmd/prime.go:691). This fails for users who don't have the gastown rig installed.

## Correct Architecture

Deacon -> ~/gt/.beads-wisp/ (town-level, no rig dependency)

Town-level ephemeral work (deacon patrols) should use town wisp storage, just like rig-level ephemeral work (witness/refinery patrols) uses rig wisp storage.

## Implementation Tasks

### 1. Town Setup (gt install / gt town init)

- Create ~/gt/.beads-wisp/ directory during town initialization
- Initialize as git repo (for local commits, not synced)
- Add config.yaml with wisp: true
- Ensure .beads-wisp/ is gitignored at town level

Files:
- internal/cmd/install.go (or equivalent town init)
- internal/town/manager.go (if exists)

### 2. Rig Setup (gt rig init)

Already creates <rig>/.beads-wisp/ - verify this is working:
- internal/rig/manager.go:375 (beadsDir := filepath.Join(rigPath, ".beads-wisp"))
- internal/rig/manager.go:394 (ensureGitignoreEntry)

### 3. Deacon Code Fixes

Update deacon to use town wisp storage:
- internal/cmd/prime.go:691 - change rigBeadsDir to townWispDir
- internal/cmd/sling.go - route deacon wisps to town level
- internal/daemon/daemon.go - any deacon-specific wisp handling

### 4. gt doctor Checks

Add/update doctor checks for wisp directories:
- internal/doctor/wisp_check.go - already checks rig wisps
- Add TownWispCheck to verify ~/gt/.beads-wisp/ exists
- Add TownWispGitCheck to verify it is a valid git repo
- Update existing checks to handle both town and rig levels

Files:
- internal/doctor/wisp_check.go (extend for town level)
- internal/doctor/checks.go (register new checks)

### 5. Documentation

- docs/beads-data-plane.md - already updated with three-tier architecture
- Verify wisp-architecture.md reflects town-level wisps

## Testing

1. Fresh gt install should create ~/gt/.beads-wisp/
2. gt doctor should pass with no rig installed
3. Deacon patrol should work without gastown rig
4. gt sling patrol deacon/ --wisp should route to town wisps


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

Current gt shutdown only kills tmux sessions but leaves:

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

This causes stale polecats to be reused on next startup.

## Expected Behavior

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

## Current Code

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

## Fix

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


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.


Polecat mood command and status line display

CLI and status line support for polecat mood.

## CLI Command
```
gt polecat mood <name> <emoji>   # Set mood
gt polecat mood <name>           # Get mood
```

Sets GT_MOOD environment variable in the polecat's tmux session.

## Status Line Integration
Update runWorkerStatusLine() to read mood:
```go
mood, _ := t.GetEnvironment(session, "GT_MOOD")
if mood != "" {
    icon = mood  // Use mood emoji instead of default
} else {
    icon = AgentTypeIcons[AgentPolecat]  // Fallback to 😺
}
```

## Storage
Mood stored in tmux session environment (ephemeral, per-session).
No persistence needed - mood is reassessed each patrol cycle.

Depends on: gt-u818 (plugin system)


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
```

gt sling to town roles should use Town beads

## Problem

When Mayor starts from ~/gt (town root), `gt mol status` couldn't find beads pinned in rig beads.

## Solution

Added cross-rig scanning for town-level roles (mayor, deacon):
1. First check local beads directory
2. If nothing found AND target is a town-level role, scan all registered rigs
3. Return first pinned bead found

This makes `gt mol status` work correctly regardless of where Mayor is when checking hook status.

## Tested

1. `gt sling gt-552hb mayor` from gastown/mayor/rig/ - pins in rig beads ✓
2. `gt mol status` from ~/gt - finds the pinned bead via cross-rig scan ✓

2. Close MR with reason:
   bd close <id> --reason='merged'
3. Close source issue (the work item):
   bd close <source_issue> --reason='Merged in <mr_id>'
4. Delete source branch (if configured):
   git push origin --delete <mr.branch>
5. Log success

Phase 2: Awareness and real-time channels (announce:, #channel)

## Scope

Extensions for awareness broadcasting and ephemeral real-time communication.

### Deliverables

1. **announce:name** - Shared single-copy bulletin board
   - Informational, not work-creating
   - Recipients check when convenient, missing is OK
   - Use case: 'Bob is refactoring logging, be aware'
2. **#channel resolution** - Dynamic tmux scan for running agents
   - #rig/gastown → tmux sessions matching gastown/*
   - #town → all Gas Town sessions
3. **gt channel publish** - Ephemeral nudge broadcast to channel

### Key semantics
- announce: shared copy (1 message, N readers) vs list: (N copies, N obligations)
- #channel ephemeral - no storage, real-time only
- Channels resolve against running sessions, not filesystem


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.


Guardrail: Verify commits exist before closing polecat issues

## Updated Approach (ZFC)

The original proposal was for mechanical guardrails in bd close. This contradicts the ZFC principle: all decisions go to models, not code.

## Correct Solution

The verification should happen in **mol-polecat-arm** execute step, not bd close:

In the pre-kill-verify action:
```bash
# Current steps
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred

# ADD: Verify productive work
git log --oneline --grep='<issue-id>' | head -1
# If no commits AND issue being closed as 'done' → flag for review
```

The agent (Witness) makes the decision. The mol gives it the verification step.

## Why Not Code Guardrails

Polecats have legitimate reasons to close issues without commits:
- Already done (someone else fixed it)
- Deferred (out of scope)
- Escalated (needs human decision)
- Duplicate (merged with another issue)

A code guardrail would block all these. The mol step lets the agent verify AND make the judgment call.

## Implementation

Update mol-polecat-arm execute step to include commit verification for 'done' closures.

Patrol 3: All agents healthy.


Unify tmux session lifecycle: prefer exec-over-shell pattern

## Context

When `gt crew at` is run from INSIDE the target session, it uses `execClaude()` which
replaces the shell with Claude directly. This is actually preferable behavior:
- Cleaner exit (no intermediate shell prompt)
- More reliable for programmatic worker recycling
- Better UX for humans

But currently this only happens accidentally when you run `gt crew at` while already
in the session at a shell prompt.

## Current behavior

1. Session created: `tmux new-session` starts with shell
2. Claude started via `send-keys` → shell spawns claude as child
3. Exit claude → return to shell → exit shell → session ends

With exec path (only if already in session):
1. `execClaude()` replaces shell with claude
2. Exit claude → session ends (no intermediate shell)

## Desired behavior

Consider making exec-the-shell the DEFAULT for all crew/persistent sessions:
- Spawn session with shell
- Wait for ready
- Use `respawn-pane -k` with claude command (kills shell, starts claude directly)

This gives the cleaner lifecycle without requiring the user to be inside the session.

Molecule-based Witness Patrol

Wire up mol-witness-patrol as a tracking ledger for the Go-based witness.

## Key Insight

The molecule is NOT an executor - it's a **tracking structure**. The existing
Go code in internal/witness/manager.go continues to run the patrol loop.
The molecule instance provides visibility, audit trail, and polecat tracking.

## Current State

- Witness runs as Go code with direct patrol logic
- mol-witness-patrol and mol-polecat-arm exist as molecule definitions
- gt mol bond creates dynamic children
- No molecule tracking of actual witness operations

## Target State

1. When witness starts → instantiate mol-witness-patrol on its hook
2. When Go code discovers polecat → bond mol-polecat-arm child
3. When polecat completes/dies → close that arm issue
4. gt mol progress shows current patrol state
5. Molecule survives wisp burns via handoff bead

## Benefits

- Visibility: gt mol status gastown/witness shows active arms
- Audit: Each polecat inspection is a trackable issue
- Consistency: Same tracking model as polecats with molecules
- Progress: gt mol progress works for witness too

## Non-Goals

- NOT replacing Go code with Claude session
- NOT running molecule steps as prompts
- NOT requiring Claude for witness operation


Phase verbs: pour and wisp commands

Implement the phase transition verbs:
- bd pour <proto> - instantiate as persistent mol
- bd wisp <proto> - instantiate as ephemeral wisp
- Update bd mol bond to inherit phase from target

These replace the current --wisp flag with cleaner verb semantics.


mol-deacon-patrol

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.


Implement town activity logging

Add centralized logging for Gas Town agent lifecycle events.

## Events to Log
- spawn: new agent created
- wake: agent resumed
- nudge: message injected
- handoff: agent handed off (intentional restart)
- done: agent finished work
- crash: agent exited unexpectedly
- kill: agent killed intentionally

## Implementation
- Add internal/log/town.go with LogEvent() function
- Log to ~/gt/logs/town.log or .beads/town.log
- Add gt log command to view/tail/filter logs
- Include timestamps, agent identity, context

## Log Format
```
2025-12-26 15:30:45 [spawn] gastown/crew/max spawned for gt-xyz
2025-12-26 15:31:02 [nudge] gastown/crew/max nudged with "start work"
2025-12-26 15:45:33 [crash] gastown/crew/max exited unexpectedly (signal 9)

- gt rig show <rig> - Show detailed rig info
- gt rig remove <rig> - Remove a rig

Pinned beads should appear first in mail inbox

Currently bd mail inbox sorts by priority then date, but pinned beads (handoff context) should always appear at the top.

**Current behavior:**
- Pinned beads mixed in with regular mail based on priority/date

**Expected behavior:**
- Pinned beads always first in inbox (before priority sorting)
- This enables handoff beads to be the default first item an agent sees

**Implementation:**
1. In mail.go runMailInbox(), after filtering, sort pinned beads to top
2. Within pinned and non-pinned groups, maintain priority/date sort

**Related:**
- gt-r8ej: Implement pinned beads for handoff state
- gt-8h4: Pinned Beads epic

**Acceptance criteria:**
- bd mail inbox shows pinned beads first
- Pinned beads still sorted by priority/date among themselves
- Non-pinned mail sorted normally after pinned section


Phase 3: Polecat Work Cycle

# Phase 3: Polecat Work Cycle

The complete lifecycle of a single polecat working a single issue.

## The Cycle

```
spawn → wake → prime → read hook → work → submit → complete → cleanup
```

## Step by Step

### 1. Spawn (Deacon/Mayor initiates)

```bash
gt spawn --issue gt-xxx --rig gastown
```

Creates fresh worktree, assigns issue, creates polecat session.

### 2. Wake (Claude starts)

Polecat Claude session starts. SessionStart hook fires.

### 3. Prime (Context loads)

```bash
gt prime  # Runs automatically via hook
```

Loads CLAUDE.md, injects beads context, checks hook.

### 4. Read Hook

gt prime finds the assigned issue on the hook:

```
## Your Hook: gt-xxx

You have been assigned this issue. Begin work now.

Title: Fix authentication bug
Priority: P1
Description: ...

Claim it with: bd update gt-xxx --status=in_progress
```

### 5. Work

Polecat:
- Claims issue: `bd update gt-xxx --status=in_progress`
- Reads relevant code
- Makes changes
- Commits with issue ID

### 6. Submit

Polecat:
- Pushes branch
- Creates MR bead: `bd create "Merge: gt-xxx" --type=merge-request`
- Signals completion

### 7. Complete

Polecat:
- Closes the issue: `bd close gt-xxx --reason "Fixed in commit abc123"`
- Syncs beads: `bd sync`

### 8. Cleanup

Polecat:
- Sends completion mail to Witness
- Session terminates (or awaits next assignment)

## The mol-polecat-work Molecule

This is already defined. The polecat should be bonded to it on spawn.

Key steps:
1. orient - Read context, understand codebase
2. claim - Update issue status
3. work - Implement the fix
4. test - Run tests, verify
5. submit - Push, create MR
6. handoff - Signal done, sync

## Implementation

### gt spawn enhancements

- Automatically pin mol-polecat-work to new polecat
- Pass issue ID as variable
- Ensure hook is set before Claude starts

### Polecat CLAUDE.md

Must include:
- Hook reading instructions
- Molecule execution pattern
- Exit state vocabulary (COMPLETED, BLOCKED, ESCALATE)

## Acceptance Criteria

- gt spawn creates polecat with issue on hook
- Polecat wakes and begins work automatically
- Polecat completes issue and submits MR
- Issue is closed with commit reference


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.


Polecat template: fix hard-to-parse sentence about persistence

This sentence is hard to parse: 'When in doubt, prefer bd—persistence you don't need beats lost context'. Rewrite for clarity, e.g., 'When in doubt, use bd for tracking - unnecessary persistence is better than lost context.'


Witness swarm landing protocol

Witness responsibilities for swarm landing cleanup.

## Trigger

Witness receives "swarm-landed" mail from Refinery containing:
- swarm_id
- merge_commit
- action: "cleanup"

## Landing Protocol

### Phase 1: Preflight
Verify all polecat sessions stopped:
- Check tmux for active sessions
- Kill any remaining sessions
- Wait for graceful shutdown

### Phase 2: Git Audit
For each polecat in swarm:
- Check for uncommitted changes
- Check for unpushed commits
- Check for stashes
- Classify as "beads-only" (safe) or "code at risk"
- If code at risk: escalate, abort landing

### Phase 3: Cleanup
For each polecat:
- Clear state entry (mark as idle)
- Delete inbox (or archive)
- Delete worker branch (local + remote)

### Phase 4: Final Report
- Update swarm state to "landed"
- File landing report bead
- Mail Mayor with summary

## Code at Risk Handling

If git audit finds code at risk:
1. Abort cleanup for that polecat
2. Mail Mayor with details
3. Human intervention required

## Reference

PGT: swarm/landing.py (6-phase protocol), swarm/git_audit.py


Survey all polecats (fanout)

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

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

For each polecat discovered, dynamically bond an inspection arm:

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

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

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

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


Runtime dynamic expansion (for-each)

Implement runtime expansion for discovered work (the for-each construct).

## Syntax

    step: survey-workers
    on-complete:
      for-each: output.polecats
      bond: mol-polecat-arm
      vars:
        polecat_name: "{item.name}"
        rig: "{item.rig}"
      parallel: true  # or sequential: true

## Design Context (from gt-8tmz.4 review)

This is **control flow**, not just expansion. It affects execution order:
- for-each with parallel: true = concurrent child execution
- for-each with sequential: true = ordered child execution

Key patrol patterns that require this:

| Pattern | Use Case |
|---------|----------|
| Witness survey-workers | For each polecat, bond an arm (parallel) |
| Refinery process-branch | For each branch in queue, run merge pipeline (sequential) |
| Deacon plugin-run | For each plugin where gate open, execute |

## Relationship to gt-8tmz.4

gt-8tmz.4 implements loop, gate, branch (static control flow).
This issue implements for-each (dynamic control flow over runtime-discovered collections).

Together they cover the full control flow needs for patrol formulas.

## Implementation Notes

- Bonds N instances based on step output
- Christmas Ornament pattern: fanout from single step to N parallel children
- Pairs with waits-for gate (gt-8tmz.38) for aggregation
- Collection must be iterable (array in step output)
- Each iteration gets item, index, and parent context in vars

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

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
```

Add gt role command group with env-based role detection

# gt role Command Group

Make role detection less fragile by using env var injection instead of cwd detection.

## Env Vars
- `GT_ROLE` - authoritative role name (mayor, witness, refinery, polecat, crew)
- `GT_ROLE_HOME` - canonical home directory for the role

## Detection Precedence
1. `$GT_ROLE` env var (authoritative)
2. Fall back to cwd-based detection (legacy/manual)
3. Warn if they disagree

## Subcommands
- `gt role` / `gt role show` - show current role
- `gt role home [ROLE]` - show home dir for role
- `gt role detect` - force cwd-based detection (debugging)
- `gt role list` - list all known roles
- `gt role env` - print export statements

## Integration Points
- gt prime - show role, warn on mismatch
- gt mol status - use gt role instead of own detection
- gt handoff - preserve GT_ROLE, reset to home
- All spawners - inject GT_ROLE and GT_ROLE_HOME

## Background
Mayor wandered to refinery dir, handoff preserved it, role detection broke.
Env var injection makes role stable across cd operations.

Plugin system: subprocess JSON protocol

Language-agnostic plugin system via subprocess JSON protocol.

## Concept

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

## Protocol

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

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

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

## Interface

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

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

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

## Plugin Discovery

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

## Built-in Hooks

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

## Use Cases

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

## Future

Consider MCP integration for richer plugin capabilities.


Polecats should not bd sync on startup

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

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

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

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

Polecat template not found for non-gastown rigs

Epic: Wisp Molecule Integration

## Vision

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

## The Steam Engine Metaphor

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

## Architecture

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

## Vocabulary

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

## Key Design Decisions

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

## Digest Contents

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

## Integration Points

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

## Phases

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

Polecat beads not synced with rig beads

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

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

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

## Root Cause

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

## Fix Options

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

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

gt park command for parking molecules on external deps

Add `gt park` command for when polecat hits external dependency:

```bash
gt park --step=gt-mol.3 --waiting="beads:mol-run-assignee"
```

This command:
1. Adds blocked_by: external:beads:mol-run-assignee to the step
2. Clears assignee on the step
3. Clears assignee on molecule root
4. Sends handoff mail to self with context
5. Shuts down polecat session

The molecule enters "parked" state (derived: in_progress + no assignee + blocked step).

Part of cross-project dependency system.

gt mail: Cross-level routing is broken

**Problem:**
When Mayor (at ~/gt) sends mail to a rig worker (gastown/crew/max), the message lands in town-level beads (~/.beads/) but the recipient checks rig-level beads (crew/max/.beads/).

**Reproduction:**
```bash
cd ~/gt
gt mail send gastown/crew/max -s 'Test' -m 'body'
# Message goes to ~/gt/.beads/ with prefix hq-*

cd ~/gt/gastown/crew/max
gt mail inbox
# Does NOT see the message - it's looking in crew/max/.beads/
```

**Root cause:**
`findBeadsWorkDir()` walks up from CWD to find .beads. `Router.Send()` runs `bd create` in that directory. This means messages always go to the sender's beads, not the recipient's.

**Fix options:**
1. Route based on recipient address - if sending to rig/*, use that rig's .beads
2. Use a single shared beads database for all mail (simpler but less isolated)
3. Teach agents to check both levels (workaround, not fix)

**Related:**
- gt-ngu1: Pinned beads sorting (done but pointless if mail doesn't route)
- This blocks all cross-level mail functionality


Add deacon/ mail identity support

Ensure deacon/ works as a mail identity in town-level beads. Test with bd mail send deacon/ and bd mail inbox --identity deacon/.

Mayor management CLI commands.

## Commands

### gt mayor start
```
gt mayor start [--continue] [--agent AGENT]
```
- --continue: Resume from previous session (check for handoff mail)
- --agent: claude (default) or other agent type

### gt mayor attach
```
gt mayor attach
```
Attach to running Mayor session.

### gt mayor stop
```
gt mayor stop [--grace-period N]
```
Stop Mayor session with optional grace period.

### gt mayor status
```
gt mayor status [--json]
```
Show Mayor running status.

## Session Management
Session name: `gt-mayor`
Working directory: `<town>/mayor/rig/` or `<town>/mayor/`

## Implementation
Similar to session commands but for special Mayor context.

```go
func getMayorPath(townRoot string) string {
    return filepath.Join(townRoot, "mayor")
}

func getMayorSessionName() string {
    return "gt-mayor"
}

Clean up ~/gt root directory cruft

The town root has accumulated various directories and files that need review:

**To evaluate:**
- daemon/ - old daemon code? move or delete?
- deacon/ - WIP deacon work? consolidate with gastown?
- mayor/ - old mayor structure?
- AGENTS.md - is this still used?
- gt binary at root - should be gitignored

**Already correct:**
- .beads/, .claude/, .gastown/, .runtime/ - runtime dirs
- beads/, gastown/ - rig directories
- docs/hop/ - strategic docs
- CLAUDE.md - mayor context

Clean up, consolidate, update .gitignore as needed.


Remove legacy .beads-wisp/ infrastructure

The wisp simplification (gt-fgms + bd-bkul) changed wisps to be just a flag on issues in the main .beads/ database. JSONL export filters Wisp=true issues. No separate directory needed.

But legacy .beads-wisp/ infrastructure still exists and should be removed:

## Gas Town (gt) cleanup:
- `internal/rig/manager.go`: Remove `initWispBeads()` call from `AddRig()`
- `internal/wisp/io.go`: Delete entire file (old abstraction layer)
- `internal/cmd/install.go`: Remove any .beads-wisp setup
- `docs/wisp-architecture.md`: Update to reflect 'just a flag' model

## Beads (bd) cleanup:
- `cmd/bd/doctor/wisp_check.go`: Remove WispExistsCheck, WispGitCheck, WispSizeCheck (check .beads-wisp dirs)
- Keep WispOrphansCheck and WispStaleCheck but rewrite to query main DB for Wisp=true issues

## Filesystem cleanup:
- Delete ~/gt/.beads-wisp/
- Delete ~/gt/gastown/.beads-wisp/
- Delete all per-rig .beads-wisp/ directories
- Remove .beads-wisp from .gitignore entries

## Verify:
- `gt mail send --wisp` still works (creates issue with Wisp=true in main DB)
- `bd sync` still filters wisps from JSONL
- `bd mol squash/burn` still work on Wisp=true issues

Evaluate pending async gates

Evaluate pending async gates.

Gates are async coordination primitives that block until conditions are met.
The Deacon is responsible for monitoring gates and closing them when ready.

**Timer gates** (await_type: timer):
Check if elapsed time since creation exceeds the timeout duration.

```bash
# List all open gates
bd gate list --json

# For each timer gate, check if elapsed:
# - CreatedAt + Timeout < Now → gate is ready to close
# - Close with: bd gate close <id> --reason "Timer elapsed"
```

**GitHub gates** (await_type: gh:run, gh:pr) - handled in separate step.

**Human/Mail gates** - require external input, skip here.

After closing a gate, the Waiters field contains mail addresses to notify.
Send a brief notification to each waiter that the gate has cleared.


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

gt spawn: Enter key needs debounce delay after paste

## Problem

When spawning polecats via `gt spawn`, instructions are pasted into tmux but workers often sit idle at prompt because the Enter key arrives before the paste is fully processed.

## Observed Behavior

- Instructions pasted via tmux send-keys
- Enter key sent immediately after
- Worker session shows prompt with no input (paste not submitted)
- Requires manual intervention to nudge workers

## Expected Behavior

- Paste completes fully
- Enter key submits the pasted instructions
- Worker begins executing immediately

## Root Cause

Likely a race condition between paste buffer processing and keypress handling. Need either:
1. Debounce delay before sending Enter
2. Longer delay (Tmax) to ensure paste completes
3. Alternative submission mechanism

## Impact

- Swarm of 10 workers had multiple stalls at startup
- Required manual tmux send-keys to unstick them
- Defeats purpose of automated spawning

## References

- Observed during Mad Max swarm (Dec 18, 2025)
- Affects gt spawn command in internal/cmd/spawn.go

## Action

2. Not stalled: `gt peek deacon/` does NOT show "> Try" prompt
3. Heartbeat fresh: `deacon/heartbeat.json` modified < 2 min ago

## OnStall
```bash

sleep 30
# Re-verify
```

## OnFail

Tests are running slow during MQ processing. Investigate and optimize:
- Profile test execution time

- Consider parallel test execution
- Cache expensive setup where possible


Check Witness and Refinery health

Check Witness and Refinery health for each rig.

**ZFC Principle**: You (Claude) make the judgment call about what is "stuck" or "unresponsive" - there are no hardcoded thresholds in Go. Read the signals, consider context, and decide.

For each rig, run:
```bash
gt witness status <rig>
gt refinery status <rig>
```

**Signals to assess:**

| Component | Healthy Signals | Concerning Signals |
|-----------|-----------------|-------------------|
| Witness | State: running, recent activity | State: not running, no heartbeat |
| Refinery | State: running, queue processing | Queue stuck, merge failures |

**Tracking unresponsive cycles:**

Maintain in your patrol state (persisted across cycles):
```
health_state:
  <rig>:
    witness:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
    refinery:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
```

**Decision matrix** (you decide the thresholds based on context):

| Cycles Unresponsive | Suggested Action |
|---------------------|------------------|
| 1-2 | Note it, check again next cycle |
| 3-4 | Attempt restart: gt witness restart <rig> |
| 5+ | Escalate to Mayor with context |

**Restart commands:**
```bash
gt witness restart <rig>
gt refinery restart <rig>
```

**Escalation:**
```bash
gt mail send mayor/ -s "Health: <rig> <component> unresponsive" \
  -m "Component has been unresponsive for N cycles. Restart attempts failed.
      Last healthy: <timestamp>
      Error signals: <details>"
```

Reset unresponsive_cycles to 0 when component responds normally.

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

## Interface

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

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

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

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

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

## Processing Loop

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

## Merge Strategy

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

## Test Integration

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

## Notifications

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

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

## Dependencies

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


Configuration in Beads: use pinned beads for rig/agent config

## Summary

Move configuration from JSON files into Beads data plane using pinned beads.

## Motivation

- Config becomes versionable and syncable like issues
- Agents can read config via `bd show`
- Unified data model for everything
- Supports the 'Beads as Universal Data Plane' vision (gt-aqm)

## Config Types to Migrate

### Rig-level (pinned per rig)
- Theme/colors for tmux status line
- Default branch naming conventions
- Merge queue settings
- Witness thresholds

### Agent-level (pinned per role)
- Handoffs (already planned - gt-cu7r)
- Agent preferences
- Current focus/context

### Town-level (pinned at town root)
- Cross-rig settings
- Federation config
- Global themes

## Implementation

1. Implement StatusPinned (beads-6v2) ✓ in progress
2. Create config pinned beads on rig init
3. Add `bd config get/set` commands that read/write pinned beads
4. Migrate existing config.json fields

## Naming Convention

```
<prefix>-cfg-<scope>
gt-cfg-theme      # gastown theme
bd-cfg-merge      # beads merge settings
gm-cfg-town       # town-level config
```

## Dependencies

- beads-6v2: Add StatusPinned to beads schema
- gm-w13: Pinned Beads epic


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.

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.

mol-gastown-boot: Mayor-driven town bootstrap

Mayor bootstraps Gas Town via a verification-gated lifecycle molecule.

## Vision

When user says "boot up gas town", Mayor slings `mol-gastown-boot` and executes it.
Each step has **action + verification** - steps stay open until outcome is confirmed.

## Key Principles

1. **No daemon-based timeouts** - Mayor keeps trying until verified
2. **Verification-gated steps** - Not "command ran" but "outcome confirmed"
3. **gt peek for verification** - Capture session output to detect stalls
4. **gt nudge for recovery** - Reliable message delivery to unstick agents
5. **Parallel where possible** - Witnesses can start in parallel
6. **Ephemeral execution** - Boot is a wisp, squashed to digest

## Proto Catalog

Town maintains a catalog of protos at `~/gt/molecules/`:

```

```

## Step Template

Each step in description includes action + verification:

```markdown
## Step: ensure-deacon

### Action
gt deacon start

### Verify
1. Session gt-deacon exists: `tmux has-session -t gt-deacon`
2. Not stalled: `gt peek deacon/` does NOT show "> Try"
3. Recent heartbeat: deacon/heartbeat.json < 2 min old

### On Stall
gt nudge deacon/ "Start patrol."
Wait 30s, re-verify.

### On Fail
Log error, continue to next step (town can run with degraded deacon)
```

## Event-Triggered Lifecycle

Beyond manual slinging, events can trigger lifecycle wisps:

| Event | Triggers |
|-------|----------|
| `gt town start` | mol-gastown-boot wisp |
| `gt rig add <name>` | mol-rig-spinup wisp |
| `gt rig remove <name>` | mol-rig-spindown wisp |
| Agent crash detected | mol-agent-restart wisp |

## Parameterization (Future)

For rig-spinup/spindown, need to pass rig name:

```bash
gt sling rig-spinup mayor/ --param rig=newproject
```

Molecule steps interpolate `${rig}` in their descriptions.

Move mol run semantics from bd into gt spawn

Currently gt spawn shells out to bd mol run for the pour+assign+pin combo. This blurs the architectural boundary between bd (data layer) and gt (orchestration layer).

## Current State
- bd mol run = bd pour + bd update --status=in_progress + bd pin --for me
- gt spawn calls: exec.Command("bd", "mol", "run", ...)

## Proposed Change
Move the combo logic into gt spawn directly:
1. gt spawn calls bd pour (create issues from template)
2. gt spawn calls bd update --status=in_progress (claim work)
3. gt spawn calls bd pin (set pinned flag)
4. gt spawn does session/tmux orchestration

This keeps bd as pure data operations and gt as the orchestration layer.

## Why
- Cleaner separation of concerns
- bd mol run feels like orchestration but it's in the data layer
- gt should own the "start a workflow" semantics

## Coordination
beads side will deprecate bd mol run once gt no longer depends on it.

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

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

## Root Cause

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

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

## Fix Options

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

## Also Affected

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

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

Daemon should auto-start as part of town bootstrap

The Go daemon should be started automatically when the town boots up (mol-gastown-boot). Currently it requires manual 'gt daemon start'.

The daemon is critical infrastructure - it monitors the Deacon and nudges it when naked. Without it, the Deacon patrol loop doesn't run.


gt orphans: Find lost polecat work

Add a command to find orphaned commits that were never merged to main.

## Problem
Polecat work can get lost when:
- Session killed before merge
- Refinery fails to process
- Network issues during push

## Solution
Add `gt orphans` command that:
1. Uses `git fsck --unreachable` to find dangling commits
2. Filters to recent commits (default: 7 days, configurable)
3. Excludes stash/index entries (WIP on, index on)
4. Shows commit details and suggests recovery

## Usage
```
gt orphans              # Last 7 days
gt orphans --days=14    # Last 2 weeks
gt orphans --recover    # Interactive cherry-pick
```

CloudRunOutpost: Basic implementation

## Overview

Basic CloudRunOutpost implementation. Persistent connections and cost tracking are separate tasks.

## Implementation

```go
type CloudRunOutpost struct {
    name        string
    project     string
    region      string
    service     string
    maxWorkers  int
    client      *WorkClient
    workers     map[string]*CloudRunWorker
    mu          sync.RWMutex
}

func NewCloudRunOutpost(cfg OutpostConfig) (*CloudRunOutpost, error) {
    serviceURL := fmt.Sprintf(
        "https://%s-%s.a.run.app",
        cfg.Service, cfg.Region,
    )
    return &CloudRunOutpost{

        client:     NewWorkClient(serviceURL),
        workers:    make(map[string]*CloudRunWorker),
    }, nil
}
```

## Spawn

```go
func (o *CloudRunOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    req := WorkRequest{
        IssueID: issue,
        Rig:     RigConfig{URL: cfg.RigURL, Branch: cfg.GitBranch},
        Beads:   BeadsConfig{URL: cfg.BeadsURL, Branch: "beads-sync"},
        Branch:  "polecat/" + issue,
    }

    events, err := o.client.DispatchWork(context.Background(), req)
    if err != nil {
        return nil, err
    }

    worker := &CloudRunWorker{
        id:      uuid.New().String(),
        outpost: o.name,

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.

Add NODE_OPTIONS crash logging to claude invocations

## Background

Investigation in bd-6df0 found that NODE_OPTIONS can enable Node.js crash reporting for Claude Code:

```bash
NODE_OPTIONS="--report-on-fatalerror --report-uncaught-exception --report-directory=$HOME/.claude/crash-reports"
```

## Proposal

Modify gt to set NODE_OPTIONS when spawning claude sessions. Key locations in gastown:

- `internal/cmd/up.go` - deacon, witness, crew, polecat spawning
- `internal/cmd/start.go` - refinery, crew spawning
- `internal/cmd/mayor.go` - mayor spawning
- `internal/cmd/handoff.go` - handoff respawning
- `internal/cmd/crew_helpers.go` - execClaude()
- `internal/daemon/lifecycle.go` - daemon-managed spawns

## Implementation

1. Create helper function to build NODE_OPTIONS string
2. Set env var before each claude invocation
3. Ensure ~/.claude/crash-reports/ directory exists
4. Optionally add `gt doctor` check to clean old reports

## Benefits

- Crash diagnostics without user config changes
- All gt-managed sessions automatically covered
- Reports available for debugging unexpected terminations

Check Witness and Refinery health

Check Witness and Refinery health for each rig.

**ZFC Principle**: You (Claude) make the judgment call about what is "stuck" or "unresponsive" - there are no hardcoded thresholds in Go. Read the signals, consider context, and decide.

For each rig, run:
```bash
gt witness status <rig>
gt refinery status <rig>
```

**Signals to assess:**

| Component | Healthy Signals | Concerning Signals |
|-----------|-----------------|-------------------|
| Witness | State: running, recent activity | State: not running, no heartbeat |
| Refinery | State: running, queue processing | Queue stuck, merge failures |

**Tracking unresponsive cycles:**

Maintain in your patrol state (persisted across cycles):
```
health_state:
  <rig>:
    witness:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
    refinery:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
```

**Decision matrix** (you decide the thresholds based on context):

| Cycles Unresponsive | Suggested Action |
|---------------------|------------------|
| 1-2 | Note it, check again next cycle |
| 3-4 | Attempt restart: gt witness restart <rig> |
| 5+ | Escalate to Mayor with context |

**Restart commands:**
```bash
gt witness restart <rig>
gt refinery restart <rig>
```

**Escalation:**
```bash
gt mail send mayor/ -s "Health: <rig> <component> unresponsive" \
  -m "Component has been unresponsive for N cycles. Restart attempts failed.
      Last healthy: <timestamp>
      Error signals: <details>"
```

Reset unresponsive_cycles to 0 when component responds normally.


Daemon: integration test with real lifecycle

Need an end-to-end test that:
1. Starts daemon
2. Starts a test agent session
3. Sends lifecycle request to daemon
4. Verifies session was killed and restarted
5. Cleans up

Polecats should auto-cleanup after MR submission

Currently polecats must manually run 'gt handoff --shutdown' after completing work. This is error-prone and leaves stale polecats around.

## Desired Flow

1. Polecat completes work
2. Polecat runs 'gt mq submit' (or similar)
3. MR is added to integration queue
4. **Polecat automatically cleans up** (no manual handoff needed)

## Implementation Options

### Option A: mq submit triggers cleanup
In 'gt mq submit':
1. Submit MR to queue
2. Automatically run cleanup (same as gt handoff --shutdown)
3. Polecat session terminates

### Option B: Refinery triggers cleanup
When Refinery picks up MR:
1. Refinery processes MR
2. Sends message to Witness: 'CLEANUP: <polecat>'
3. Witness cleans up polecat

### Option C: Molecule-driven
Define cleanup as final phase of polecat-work molecule:
1. code → test → submit-mr → cleanup

## Note
This reinforces the ephemeral model: polecats exist only for the duration of a single task.

Haiku-based smart stuck detection

Use Haiku to analyze tmux state when signals are ambiguous.

## When to Invoke

Only as escalation tier:
1. Keepalive is stale (> 2 min)
2. Tmux shows claude is running (not idle shell)
3. Heuristics can't determine state

## Prompt

Capture last 50 lines of tmux pane, ask Haiku:
'Is this Claude agent: WORKING | STUCK | IDLE | WAITING_FOR_HUMAN?'

## Cost

~$0.001 per check. At 1 check/min worst case = $0.06/hour.
In practice, most checks avoided by keepalive signal.

## Configuration

```toml
[daemon]
smart_detection = true
smart_model = "haiku"
smart_threshold = "2m"  # only check if stale > 2min
```


New Year's Launch: Single-Polecat Engine

# Tracer Bullet: Single-Polecat Engine

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

## Vision

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

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

## Key Insight: Molecules Are the Logic

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

## The Propulsion Principle

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

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

## Critical Path

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

## Success Criteria

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

## Non-Goals (v0.1)

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

These are v0.2+. Tracer bullet first.

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.


Digest: mol-deacon-patrol

Patrol complete: 0 messages, agents healthy, no cleanup needed


Nudge newly spawned polecats

Nudge newly spawned polecats that are ready for input.

When polecats are spawned, their Claude session takes 10-20 seconds to initialize.
The spawn command returns immediately without waiting. This step finds spawned
polecats that are now ready and sends them a trigger to start working.

```bash
# For each rig with polecats
for rig in gastown beads; do
    gt polecats $rig
    # For each working polecat, check if Claude is ready
    # Use tmux capture-pane to look for "> " prompt
done
```

For each ready polecat that hasn't been triggered yet:
1. Send "Begin." to trigger UserPromptSubmit hook
2. The hook injects mail, polecat sees its assignment
3. Mark polecat as triggered in state

Use WaitForClaudeReady from tmux package (polls for "> " prompt).
Timeout: 60 seconds per polecat. If not ready, try again next cycle.


Handle callbacks from agents

Handle callbacks from agents.

Check the Mayor's inbox for messages from:
- Witnesses reporting polecat status
- Refineries reporting merge results
- Polecats requesting help or escalation
- External triggers (webhooks, timers)

```bash
gt mail inbox
# For each message:
gt mail read <id>
# Handle based on message type
```

Callbacks may spawn new polecats, update issue state, or trigger other actions.

Ephemeral rig support for ad-hoc batch work

Support for temporary worker rigs for ad-hoc batch work.

## Use Case

Ad-hoc batch work where you want temporary workers:
- gt spawn --epic <epic-id> --ephemeral --workers 3
- Creates temp rig with 3 clones
- Workers process epic children
- Work merges through queue
- Clones cleaned up when done

## Interface

```go
type EphemeralRig struct {
    ID               string
    GitURL           string
    BaseCommit       string
    Workers          []string
    IntegrationBranch string
    EpicID           string  // associated epic (for cleanup trigger)
    CreatedAt        time.Time
}

func InitEphemeralRig(gitURL string, numWorkers int) (*EphemeralRig, error)
func (r *EphemeralRig) AddWorker(name string) error
func (r *EphemeralRig) Destroy(force bool) error
```

## Directory Structure

```
<rig>/ephemeral/
└── rig-a3f7/
    ├── config.json
    ├── Alice/     # clone
    ├── Bob/       # clone
    └── Carol/     # clone
```

## Cleanup Trigger

When all issues in the associated epic are closed AND merged, the ephemeral rig can be destroyed.

## Note

No swarm ID needed - the epic ID provides the grouping. Ephemeral rig is just a convenience for temporary clones.

## Reference

PGT: ephemeral.py (for structure, ignore swarm ID coupling)


Plugin: Plan-to-Epic converter

## Purpose

Help users create beads epics from various planning inputs.

## Inputs
- Markdown task lists
- GitHub issues
- Linear/Jira exports
- Free-form descriptions
- Existing beads epics

## Output
- Beads epic with properly structured children
- Dependencies set for wave ordering
- Priorities assigned
- Ready for `gt spawn --epic <id>`

## Implementation Options

### Option A: CLI Tool
```bash
gt plan import --from github --repo owner/repo --label batch-candidate
gt plan import --from markdown tasks.md
gt plan structure <epic-id>  # analyze and add dependencies
```

### Option B: Plugin Agent
A plugin at `<rig>/plugins/plan-oracle/` that:
- Receives planning requests via mail
- Analyzes scope and requirements
- Creates structured beads epic
- Sets dependencies based on analysis

### Option C: Interactive Mode
```bash
gt plan create
# Walks through questions, creates epic interactively
```

## Axiom

As stated: 'The Planning phase should end in the creation of a workable Beads plan.'

This plugin bridges the gap between human planning and machine-executable work.

## Priority

P2 - Nice to have for MVP. Manual epic creation works for now.

## Note

No "swarm IDs" - output is just a beads epic with children. Workers process it independently.


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.

Human and mail gates

Implement human:<prompt> gate (requires explicit approval command). Implement mail:<pattern> gate (waits for mail matching pattern). These enable async human-in-loop workflows.


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.


Outpost integration tests: Mock and E2E testing

## Overview

Integration tests for the outpost system.

## Mock Outpost

```go
type MockOutpost struct {
    name        string
    maxWorkers  int
    spawnDelay  time.Duration
    spawnError  error
    workers     []*MockWorker
}

func (o *MockOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    if o.spawnError != nil {
        return nil, o.spawnError
    }
    time.Sleep(o.spawnDelay)
    worker := &MockWorker{id: uuid.New().String(), issue: issue}
    o.workers = append(o.workers, worker)
    return worker, nil
}
```

## Unit Tests

```go
func TestOutpostManager_SelectOutpost(t *testing.T) {
    // Test policy-based selection
}

func TestOutpostManager_SpawnWithRetry(t *testing.T) {
    // Test retry logic with transient failures
}

func TestCloudRunOutpost_CostTracking(t *testing.T) {
    // Test cost calculation and caps
}
```

## Integration Tests (with mocked Cloud Run)

```go
func TestCloudRunOutpost_Integration(t *testing.T) {
    // Start mock HTTP server
    server := httptest.NewServer(mockWorkHandler())
    defer server.Close()

    outpost := NewCloudRunOutpost(OutpostConfig{
        ServiceURL: server.URL,
    })

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

## E2E Tests (requires real Cloud Run)

```go
// +build e2e

func TestCloudRunOutpost_E2E(t *testing.T) {
    if os.Getenv("CLOUDRUN_SERVICE_URL") == "" {
        t.Skip("CLOUDRUN_SERVICE_URL not set")
    }
    // Test against real Cloud Run service
}
```

type WorkRequest struct {
    IssueID string          `json:"issue_id"`
    Rig     RigConfig       `json:"rig"`
    Beads   BeadsConfig     `json:"beads"`
    Branch  string          `json:"worker_branch"`
    Context map[string]any  `json:"context,omitempty"`
}

type RigConfig struct {
    URL    string `json:"url"`
    Branch string `json:"branch"`
}

type BeadsConfig struct {
    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"`

    Branch  string `json:"branch"`
    PRURL   string `json:"pr_url,omitempty"`
    Error   string `json:"error,omitempty"`
}
```

## Files

- `internal/cloudrun/protocol.go` - All types above

## Notes

This is just types. Server (gt-9a2.7b) and client (gt-9a2.7c) are separate tasks.
Small, focused task - can complete quickly.

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)

Witness commands: gt witness start/stop/status needed

## Summary

No `gt witness` command exists. The witness should:
- Monitor polecats for stuck/idle state
- Nudge polecats that seem blocked
- Report status to mayor
- Handle polecat lifecycle

## Expected Commands

```bash
gt witness start gastown   # Start witness for rig
gt witness stop gastown    # Stop witness
gt witness status          # Show witness status
```

## Current State

- Witness directory exists: /Users/stevey/gt/gastown/witness/
- Has state.json but no active process
- gt status shows 'Witnesses: 0'

## Context

Full polecat flow needs witness monitoring for production use.


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.

Consolidate configuration architecture: three-tier model

Rationalize Gas Town's scattered configuration into a clean three-tier model:

## Current Problems
- Config split across mayor/, .gastown/, and rig/config.json
- Runtime state mixed with configuration
- Hidden directories (.gastown/) are missed by agents
- Category confusion: identity vs config vs runtime state

## Proposed Architecture

### Tier 1: Town Config (mayor/)
```
mayor/
├── town.json      # Town identity (unchanged)
├── rigs.json      # Rig registry (unchanged)
└── config.json    # NEW: Town-level configuration
    # theme defaults, daemon settings, etc.
```

### Tier 2: Town Runtime (.runtime/)
```
~/gt/.runtime/                    # NEW: Gitignored
├── daemon.json                   # {pid, started_at, heartbeat}
├── deacon.json                   # {cycle, last_action}
└── agent-requests.json           # Lifecycle requests
```

### Tier 3: Rig Config (settings/)
```
<rig>/
├── config.json                   # Rig identity only (type, git_url, beads.prefix)
├── settings/                     # NEW: Visible, git-tracked
│   ├── config.json               # theme, merge_queue, max_workers
│   ├── namepool.json             # pool settings (style, max)
│   └── roles/                    # Per-role overrides (optional)
└── .runtime/                     # NEW: Gitignored
    ├── witness.json              # {state, started_at, stats}
    ├── refinery.json             # {state, started_at, stats}
    └── namepool-state.json       # {in_use, overflow_next}
```

## Key Principles
1. **Visible > Hidden** for config agents need to find
2. **Git-tracked** for identity and config; **gitignored** for runtime
3. **Separation of concerns**: identity, config, runtime are distinct
4. **Locality**: town config at town root, rig config at rig root

## Migration
- Move .gastown/ contents to appropriate new locations
- Update all code that reads/writes these files
- Update .gitignore patterns
- Update documentation (architecture.md, CLAUDE.md)
