Test polecat lifecycle end-to-end

Test the full polecat lifecycle:

1. **Spawn**: Sling a test issue to a polecat
```bash
bd create --title="Test issue for polecat" --type=task
gt sling gt-<id> gastown
```

2. **Execute**: Watch polecat work
```bash
tmux attach -t gt-gastown-<name>
```

3. **Complete**: Polecat should:
   - Close the issue: `bd close gt-<id>`
   - Commit work: `git commit && git push`
   - Send POLECAT_DONE mail to witness

4. **Cleanup**: Witness should:
   - Receive POLECAT_DONE
   - Verify git state clean
   - Kill session and remove worktree

Success: Issue closed, PR merged, polecat cleaned up.


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


Witness MVP: Automated Polecat Lifecycle

Implement the Witness agent - per-rig 'pit boss' that manages polecat lifecycles.

The Witness enables hands-free swarming by automating:
- Spawning polecats for ready work
- Monitoring worker health
- Processing shutdown requests
- Cleaning up worktrees when done
- Escalating stuck workers to Mayor

Without Witness, humans must manually spawn, monitor, and kill each polecat.

## Core Loop

```
while True:
  # Handle pending shutdowns
  for polecat in polecats where state == pending_shutdown:
    verify git clean
    kill session
    remove worktree
    delete branch

  # Spawn for ready work
  ready = bd ready --parent=<epic> if epic else bd ready
  for issue in ready:
    if active_workers < max_workers:
      gt spawn --issue <id>

  # Check worker health
  for polecat in active polecats:
    if stuck (no progress for 30 min):
      nudge or escalate

  sleep 60
```

## Blocking Bugs to Fix
- gt-dsfi: handoff deadlock
- gt-n7z7: refinery foreground race condition
- gm-c6b: mail coordination (town vs rig beads)


Phase 5.2: Ephemeral error handling and recovery

Handle edge cases in ephemeral molecule lifecycle.

## Scenarios

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

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

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

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

## Implementation

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

## Key Concepts

1. **Campaign** (gt-camx5): Molecule-wrapped Epic graph for orchestrated execution
2. **Schematic** (gt-8ws7o): Domain-level formula composition
3. **Protocol** (gt-y3jb9): Type system for formulas
4. **SDK** (gt-ihzqr): Developer tooling (Forge, Lab, Validator)
5. **Mol Mall** (gt-vm85o): Package registry for distribution

## Design Principles

- Chemistry metaphor: atoms → molecules → compounds → materials
- Two orthogonal dimensions: work tracking × workflow execution
- Campaign is the convergence point
- Everything compiles down to executable molecules

CLI: cleanup commands for stale state

Cleanup commands for recovering from stale state.

## Commands

### gt cleanup <polecat>
Clean stale state for specific polecat.
```
gt cleanup <rig>/<polecat> [--dry-run]
```

Actions:
- Remove orphaned state.json if clone missing
- Clear stale session references
- Reset stuck state (working → idle after timeout)

### gt cleanup --all
Clean all polecats in workspace.
```
gt cleanup --all [--dry-run]
```

## Implementation
```go
func CleanupPolecat(rigName, polecatName string, dryRun bool) (*CleanupResult, error)

type CleanupResult struct {
    OrphanedStateRemoved bool
    SessionsCleared      int
    StateReset           bool
    Warnings             []string
}
```

## Overlap with Doctor
- Doctor diagnoses and offers --fix
- Cleanup is more aggressive state recovery
- Consider merging into doctor --fix

## New File
internal/cmd/cleanup.go

## Acceptance Criteria
- [ ] Removes orphaned state files
- [ ] Clears stale session refs
- [ ] --dry-run shows what would happen
- [ ] Reports all actions taken

Patrol cycle 2: Processed 3 POLECAT_DONE (nux=ESCALATED, slit=DEFERRED, furiosa=COMPLETED). Wrong-rig issue escalated to Mayor. All 3 gastown polecat sessions stopped.


Update lifecycle mail targets to deacon/

Update Mayor, Witness, and Crew handoff code to send lifecycle requests to deacon/ instead of daemon/. Update internal/cmd/handoff.go and related code.


CRITICAL: gt doctor orphan-processes kills active crew sessions

## Problem

The deacon's patrol runs `gt doctor --fix` which includes an orphan-processes check. This check is incorrectly identifying ACTIVE crew sessions as orphaned and killing them.

## Impact

- Crew workers are being killed mid-session
- Work is lost
- The deacon is currently disabled until this is fixed

## Root Cause

The orphan-processes detection logic in `internal/doctor/` doesn't properly identify crew workers. It likely:
1. Doesn't recognize the `gt-<rig>-<name>` session pattern for crew
2. Or misidentifies the Claude process as orphaned when it has a valid tmux parent

## Workaround

The patrol formula was updated to instruct deacon not to run `--fix` if orphan-processes reports any PIDs. But this workaround failed - the deacon still killed crew.

## Fix Required

1. Update `internal/doctor/identity_check.go` or `branch_check.go` to properly detect crew sessions
2. Add crew session patterns to the valid session detection
3. Add test coverage for crew worker scenarios

## Files

- internal/doctor/identity_check.go

Silent error handling with _ = err patterns

Multiple locations intentionally ignore errors with comments like 'Ignore errors'. While some are valid (best-effort operations), others should be audited:

- witness/manager.go:542 - Ignores cmd.Run() error
- refinery/manager.go:411, 438, 509 - Ignores loadState and git pull errors
- swarm/manager.go:47 - Ignores getGitHead error
- polecat/manager.go:69, 284 - Ignores pool.Load and DeleteBranch errors
- swarm/integration.go:101, 137 - Ignores git pull and push errors

Each should be evaluated: log it, handle it, or confirm ignoring is intentional.

Patrols: Cyclic molecules for autonomous maintenance

## Vision

Patrols are **cyclic molecules** - workflow loops that give Gas Town its autonomous nervous system. While regular molecules are DAGs that terminate, patrols loop forever, performing maintenance tasks at varying cadences.

This is the "steam engine" of Gas Town: converting episodic Claude sessions into continuous autonomous operation.

## Core Concepts

### 1. Cyclic Molecules

Regular molecule:     A -> B -> C -> done
Patrol molecule:      A -> B -> C --+
                      ^             |
                      +-------------+

Patrols have a loop_to field specifying where to restart.

### 2. Cooldown-Aware Steps (Atoms)

Steps encode their own cadence. When patrol reaches a step:
1. Check: now - last_run > cooldown?
2. If yes: execute, update last_run
3. If no: skip (immediately close)

The patrol runner is simple - steps self-skip. Complexity distributed into atoms.

### 3. The Beacon

The heartbeat that fires patrol triggers:
- Internal ticker in Deacon (goroutine)
- Or external cron firing gt deacon tick
- Or mail-based triggers

Without beacon, nothing proactive happens.

### 4. Session Reset as Patrol Step

Connects to auto-handoff (gt-bcwn). Session reset is a patrol step, not a separate mechanism.

### 5. Multi-Role Patrols

Each supervisor has its own patrol:

**Deacon patrol:** health-check (30s), session-gc (5m), beacon-tick (10s)
**Witness patrol:** orphan-scan (10m), stuck-check (2m), molecule-progress (1m)
**Refinery patrol:** queue-check (30s), pr-status (1m), merge-ready (30s)

### 6. Cadence Tiers

- Critical (10-30s): Health checks
- Active (1-5m): Progress, nudges
- Maintenance (10-30m): Orphans, GC
- Periodic (1h+): Reports

### 7. Best-Effort Scheduling

Not real-time - more like cron. No hard deadlines. Catch-up, dont pile-up.
Priority preemption (mail interrupts patrol). Graceful degradation under load.

## Open Questions

1. State persistence: Beads (self-describing) or file (faster)?
2. Interruption: How does urgent mail preempt patrol?
3. Error recovery: Backoff? Escalate? Circuit breaker?
4. Coordination: Can patrols send mail to trigger other patrols?

## Related

- gt-bcwn: Auto-handoff (session reset is a patrol step)
- Molecule system (patrols extend molecules with loops)
- Deacon lifecycle management

## Metaphor

Claude was fire. Claude Code was steam. Gas Town is the steam engine. Beads is the train tracks.

The steam engine converts episodic combustion into continuous rotary motion.
Gas Town converts episodic Claude sessions into continuous autonomous work.


Add Deacon heartbeat mechanism

Deacon writes deacon/heartbeat.json on each wake. Go daemon reads it to decide whether to poke. Add heartbeat read/write helpers.


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.

- internal/mrqueue/ - MR queue management
- internal/claude/ - Claude integration
- internal/style/ - Terminal styling
- internal/constants/ - Constants

Priority for testing:
1. lock/ - prevents duplicate agents, critical for correctness
2. witness/ - agent lifecycle management
3. mrqueue/ - merge request processing

Overall: 37 test files for 160 Go files (23% by file count)


Day 1.3: Implement bd slot set/clear commands

Add slot management commands:
- bd slot set <agent> <slot> <bead> - set slot (error if occupied)
- bd slot clear <agent> <slot> - clear slot
- bd slot show <agent> - show all slots

These enforce cardinality constraints.

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.

Polecat template: move startup announcement into molecule

Template has STARTUP PROTOCOL with 'Announce: beads Polecat furiosa, checking in.' This should be a startup step in the polecat molecule, not prose instruction in CLAUDE.md. The molecule drives behavior, not the template prose.


Molecule CLI: bd molecule commands

Add molecule commands to bd:

## Commands

```bash
bd molecule list              # List molecules (type: molecule)
bd molecule show <id>         # Show molecule with parsed steps
bd molecule parse <id>        # Validate and show parsed structure
bd molecule instantiate <mol-id> --parent=<issue-id>  # Create steps
bd molecule instances <mol-id>  # Show all instantiations
```

## gt spawn integration

```bash
gt spawn --issue <id> --molecule <mol-id>
```

This should:
1. Call `bd molecule instantiate` (creates child beads atomically)
2. Spawn polecat on first ready step
3. Polecat grinds through via `bd ready`

## Output Examples

```
$ bd molecule show mol-abc

mol-abc: Engineer in a Box
Type: molecule

Steps (5):
  design      → (ready first)
  implement   → Needs: design
  review      → Needs: implement
  test        → Needs: implement
  submit      → Needs: review, test

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).


Refinery Role Definition

You are the Refinery - merge queue processor for your rig. You process
completed polecat work, merging it to main one branch at a time with
sequential rebasing.

Your mission: Process the merge queue sequentially, rebasing each branch
atop the current baseline before merging.

default_molecule: mol-refinery-patrol
capabilities:
  - merge_queue_processing
  - sequential_rebase
  - conflict_resolution
  - verification_gates

## The Engineer Mindset

You are Scotty in the engine room. The merge queue is your warp core.

The Beads Promise: Work is never lost. If you discover ANY problem:
1. Fix it now (preferred if quick), OR
2. File a bead and proceed (tracked for cleanup crew)

There is NO third option. Never "disavow" by noting something exists and moving on.

The Scotty Test: Before proceeding past any failure, ask yourself:
"Would Scotty walk past a warp core leak because it existed before his shift?"

## Propulsion Principle

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

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

## Sequential Rebase Protocol

WRONG (parallel merge - causes conflicts):
  main -> branch-A (old main) + branch-B (old main) = CONFLICTS

RIGHT (sequential rebase):
  main -> merge A (rebased on main) -> merge B (rebased on main+A)

After every merge, main moves. Next branch MUST rebase on new baseline.

## Verification Gate

The handle-failures step is a verification gate:
- Tests PASSED: Gate satisfied, proceed to merge
- Tests FAILED (branch caused): Abort, notify polecat, skip branch
- Tests FAILED (pre-existing): MUST fix OR file bead - cannot proceed without

## Commands

### Patrol
- gt mol status - Check attached patrol
- bd ready / bd show / bd close - Step management
- bd mol spawn <mol> --wisp - Spawn patrol wisp

### Git Operations
- git fetch origin - Fetch all remote branches
- git branch -r | grep polecat - List polecat branches
- git rebase origin/main - Rebase on current main
- git push origin main - Push merged changes

### Communication
- gt mail inbox - Check for messages
- gt mail send <addr> -s "Subject" -m "Message" - Notify workers

Witness daemon: heartbeat loop, spawn ephemeral agent

Background daemon for agent lifecycle and monitoring.

## Core Responsibilities

1. **Heartbeat monitoring**: Check agent health periodically
2. **Session lifecycle**: Restart agents after handoff (Witness Protection)
3. **Polecat monitoring**: Track worker progress, nudging
4. **Escalation**: Report failures to Mayor

## Session Lifecycle (Witness Protection)

The daemon enables autonomous long-running operation by cycling agent sessions:

```go
type SessionLifecycle struct {
    AgentType string  // "witness", "refinery"
    StatePath string  // path to state.json
}

func (d *Daemon) monitorSessionLifecycle(agent SessionLifecycle) {
    // 1. Detect session exit
    // 2. Check state.json for requesting_cycle: true
    // 3. If cycle requested: start new session, clear flag
    // 4. If unexpected exit: escalate to Mayor
}
```

See architecture.md Key Decision #12: Agent Session Lifecycle.

## Interface

```go
type Daemon struct {
    rig      *Rig
    polecats *PolecatManager
    sessions *SessionManager
    config   DaemonConfig
}

type DaemonConfig struct {
    HeartbeatInterval time.Duration  // default: 30s
    NudgeThreshold    int            // nudges before escalation
    MaxWorkers        int            // from rig config
}

func NewDaemon(rig *Rig) *Daemon
func (d *Daemon) Start() error
func (d *Daemon) Stop() error

// Lifecycle
func (d *Daemon) CycleSession(agentType string) error
func (d *Daemon) SpawnWorker(issueID string) error
func (d *Daemon) ShutdownWorker(polecat string) error
```

## Heartbeat Loop

Every HeartbeatInterval:
1. Check Witness session (restart if cycle requested)
2. Check Refinery session (restart if cycle requested)
3. For each active polecat: assess progress, nudge if stuck
4. Query `bd ready` for new work, spawn up to max_workers

Clean dead sessions

Clean dead sessions and orphaned state.

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

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

# Fix everything
gt doctor --fix
```

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

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


Verify refinery patrol loop executes

Verify refineries run their patrol formula:

1. Check refinery session: `gt session status gastown/refinery`
2. If not running: `gt session start gastown/refinery`
3. Watch refinery: `tmux attach -t gt-gastown-refinery`
4. Verify it handles:
   - Checking for pending MRs
   - Processing merge queue
   - Reporting results

Test for both rigs: gastown and beads.

Wraps: `bd mail inbox [--json]`

### gt mail read
```
gt mail read <id>
```
Wraps: `bd mail read <id> && bd mail ack <id>`
Note: bd mail read + ack marks as read.

### gt mail send
```
gt mail send <address> -s "Subject" -m "Body" [--notify]
```
Wraps: `bd mail send <recipient> -s "Subject" -m "Body"`
If --notify: inject tmux notification after send.

### gt mail delete
```
gt mail delete <id>
```
Wraps: `bd mail ack <id>` (closes the message issue)

Distinguish two cooking modes: 1) Compile-time: produces proto with variable placeholders, for modeling/estimation/contractor handoff. 2) Runtime: produces mol with real issue IDs. Compile-time lets you pre-decompose work for untrusted executors or planning purposes.

Witness: aggregate completion and notify Mayor

## Problem
No signal when swarm completes. Mayor must manually check.

## ZFC-Compliant Solution
Add step to `mol-witness-patrol.formula.toml`:

```toml
[[step]]
id = "check-swarm-completion"
title = "Report swarm completion to Mayor"
description = """
1. Check state.json for active swarm tracking:
   - swarm_id, start_time, assigned_beads[], completed_beads[]
2. For each completed merge (from cleanup step):
   - Add bead to completed_beads
3. If all assigned_beads are in completed_beads:
   - Calculate duration
   - Send summary to Mayor:
     gt mail send mayor/ -s "SWARM_COMPLETE: <swarm_id>" -m "All N polecats merged in Xm"
   - Clear swarm tracking from state.json
"""
depends_on = ["cleanup-merged-polecats"]
```

## Swarm Initialization
When Mayor slings a batch, they should:
```bash
# Mayor creates swarm tracking
gt mail send <rig>/witness -s "SWARM_START" -m '{"swarm_id": "batch-123", "beads": ["bd-a", "bd-b", "bd-c"]}'
```

Witness parses SWARM_START and initializes tracking in state.json.

## Why This Works
- Mayor initiates batch with SWARM_START mail
- Witness tracks progress in its own state
- Witness signals completion via mail
- All coordination is agent-to-agent via mail

## Files
- formulas/mol-witness-patrol.formula.toml


Molecule format bridge: convert embedded markdown to child issues

## Problem

Two molecule formats exist:
1. **Old (gastown builtin)**: Steps embedded as markdown in Description field, parsed by ParseMoleculeSteps()
2. **New (bd mol)**: Steps as child issues in proper beads DAG

The daemon's InstantiateMolecule() uses the old format. bd mol spawn uses the new format.

## Options

### Option A: Require child issues (new format)
- Update daemon to use bd mol spawn instead of InstantiateMolecule
- Deprecate embedded markdown format
- Pro: One format, simpler
- Con: Breaking change for existing molecules

### Option B: Build a bridge
- In InstantiateMolecule, detect format:
  - If Description has ## Step: markers → parse to child issues
  - If issue has children with template label → use directly
- Convert old format to new format on instantiation
- Pro: Backward compatible
- Con: More complexity

## Recommendation

Option B - build the bridge. On instantiation, convert markdown steps to child issues. This unifies execution while preserving authoring flexibility.

Phase 1: Core messaging primitives (@group, list:, queue:)

## Scope

Core messaging infrastructure that enables multi-recipient and work-queue patterns.

### Deliverables

1. **Config directory structure** - ~/gt/config/ with lists.json, queues.json
2. **@group dynamic resolution** - Filesystem scan for agent directories
   - @rig/gastown → scan gastown/ for agents
   - @town → scan all rigs
   - @witnesses, @crew/gastown, etc.
3. **list:name static lookup** - Fan-out to N copies (each recipient gets work item)
4. **queue:name with claim** - Shared storage, atomic claim via bd update --claim
5. **Fan-out at send time** - gt mail send handles expansion

### Key semantics
- @group and list: both fan out (N copies, N obligations)
- queue: shared copy, first-to-claim wins
- All resolve at send time, not receive time

Witness session cycling and handoff

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

## Session Cycling Protocol

```markdown
## Session Cycling

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

### Handoff Protocol

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

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

## Active Workers
<list workers and status>

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

## Recent Actions
<last 3-5 actions>

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

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

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

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

### On Fresh Session Start

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

## Implementation

Add to WITNESS_CLAUDE.md template.

Patrol agents subscribe to bd activity --follow

Each patrol agent (Deacon, Witness, Refinery) should run bd activity --follow as a background process. Any output line is a wake signal. This is the primary wake mechanism.

Implementation:
1. Add feed subscription to await-signal step logic
2. Agent starts bd activity --follow on entering await-signal
3. Any line of output breaks the wait immediately
4. Timeout still applies as safety net

Enhanced polecat decommission prompting

Add decommission checklist to polecat AGENTS.md.template. Make crystal clear: verify ALL before signaling done.

## Checklist for AGENTS.md.template

```markdown
## Decommission Checklist

**CRITICAL**: Before signaling done, you MUST complete this checklist.
The Witness will verify each item and bounce you back if dirty.

### Pre-Done Verification

```bash
# 1. Git status - must be clean
git status
# Expected: "nothing to commit, working tree clean"

# 2. Stash list - must be empty
git stash list
# Expected: (empty output)

# 3. Beads sync - must be up to date
bd sync --status
# Expected: "Up to date" or "Nothing to sync"

# 4. Branch merged - your work must be on main
git log main --oneline -1
git log HEAD --oneline -1
# Expected: Same commit
```

### If Any Check Fails

- **Uncommitted changes**: Commit them or discard if unnecessary
- **Stashes**: Pop and commit, or drop if obsolete
- **Beads out of sync**: Run `bd sync`
- **Branch not merged**: Complete the merge workflow

### Signaling Done

Only after ALL checks pass:

```bash
bd close <issue-id>
bd sync
town mail send <rig>/witness -s "Work Complete" -m "Issue <id> done."
```
```

## Implementation

Add to AGENTS.md.template in the polecat prompting section.


Add gt deacon start/stop/status commands

Add CLI commands: gt deacon start (spawn gt-deacon session), gt deacon stop (kill session), gt deacon status (show health state). Similar to gt mayor commands.


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

Patrol 4: All healthy


Witness Role Definition

You are the Witness - per-rig worker monitor. You watch polecats, nudge them
toward completion, verify clean git state before kills, and escalate stuck
workers to the Mayor.

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

default_molecule: mol-witness-patrol
capabilities:
  - monitor_workers
  - nudge_stuck
  - pre_kill_verify
  - session_lifecycle
  - escalation

## Core Responsibilities

1. Monitor workers: Track polecat health and progress
2. Nudge: Prompt slow workers toward completion
3. Pre-kill verification: Ensure git state is clean before killing sessions
4. Session lifecycle: Kill sessions, update worker state
5. Self-cycling: Hand off to fresh session when context fills
6. Escalation: Report stuck workers to Mayor

Key principle: You own ALL per-worker cleanup. Mayor is never involved in
routine worker management.

## Propulsion Principle

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

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

## Nudge Protocol

Progress through stages. Track nudge count per worker per issue.
- First Nudge (10+ min idle): Gentle inquiry
- Second Nudge (15 min): Direct question
- Third Nudge (20 min): Final warning
After 3 nudges with no progress -> escalate to Mayor

## Pre-Kill Verification

Before killing ANY polecat session:
1. gt polecat git-state <name> - Must be clean
2. Check for uncommitted work
3. Check for unpushed commits
4. Verify issue closed
5. Verify PR submitted (if applicable)

## Commands

- gt polecat list <rig> - See all polecats
- gt polecat git-state <name> - Check git cleanliness
- tmux capture-pane -t gt-<rig>-<name> -p | tail -40 - Session inspection
- gt mail inbox - Check messages
- gt mail send mayor/ -s "Subject" -m "Message" - Escalate


Merge execution: merge, test, push

Implement the actual merge execution.

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

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

Handle push failures with retry logic.

Deacon stuck-session detection and force-kill protocol

Deacon detects and kills genuinely stuck/hung Claude Code sessions.

## The Problem

Claude Code sessions can get stuck:
- Infinite loop / hung tool call
- Crashed but tmux session still exists
- Unresponsive to nudges

`gt rig boot` is idempotent (won't kill) - it only starts if not running.
Someone needs to detect stuck sessions and force-kill them.

## Detection Protocol

During Deacon health rounds:

1. **Ping test**: `gt nudge <agent> 'HEALTH_CHECK'`
2. **Wait for response**: Agent should update agent bead `last_activity`
3. **Timeout**: If no activity update within N seconds, mark suspicious
4. **Consecutive failures**: After M consecutive failures, declare stuck

## Force-Kill Protocol

When stuck detected:

```bash
# 1. Log the intervention
gt mail send <agent> -s 'FORCE_KILL: unresponsive' -m 'Deacon detected...'

# 2. Kill the tmux session
tmux kill-session -t <session-name>

# 3. Update agent bead state
bd update <agent-bead> --status=killed --reason='Deacon force-kill: unresponsive'

# 4. Notify mayor (optional, for visibility)
gt mail send mayor/ -s 'Agent killed: <agent>' -m 'Reason: unresponsive...'
```

## Recovery

After force-kill, the agent is 'asleep'. Normal wake mechanisms apply:
- `gt rig boot` restarts it
- Or stays asleep until next activity trigger

## Parameters (configurable)

- ping_timeout: 30s (how long to wait for response)
- consecutive_failures: 3 (how many before force-kill)
- cooldown: 5m (minimum time between force-kills of same agent)

## NOT Deacon's Job

- Graceful shutdown (agent does this itself)
- Context-based recycling (agent self-handoffs)
- Normal backoff/sleep transitions

Deacon only force-kills when agent is genuinely unresponsive.

Define constants for magic strings

Several magic strings are hardcoded throughout the codebase:
- "mayor" appears in 20+ places as a path component
- "main" branch name appears in 20+ places
- "beads-sync" branch name in multiple files
- "rigs.json" filename

These should be constants in a central location for maintainability.


Beads CLI wrapper: shell out to bd

Wrapper for bd (beads CLI) commands.

## Interface

```go
type Beads struct {
    workDir string
}

func NewBeads(workDir string) *Beads

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

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

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

## Data Types

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

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

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

## Implementation

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

## Error Handling

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


Refactor gt swarm to use beads backing

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

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

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

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

Fanout gate: waits-for children aggregation

Formalize the fanout gate pattern where a step waits for all dynamically-bonded children.

## Current State

Formulas already use this pattern informally:

    step: aggregate
    waits_for: "all-children"

But it is not in the algebra spec or implemented in the cooker.

## Proposed Syntax

    step: aggregate
    needs: [survey-workers]
    waits-for: children-of(survey-workers)

Or simpler:

    step: aggregate
    needs: [survey-workers]
    waits-for: all-children

## Semantics

- Step cannot start until ALL children of the referenced step have completed
- Children are dynamically bonded via for-each (gt-8tmz.8)
- This is the "aggregation" half of the Christmas Ornament pattern
- If no children were bonded, the gate passes immediately

## Use Cases

**Witness Patrol:**
- survey-workers bonds N polecat-arms
- aggregate waits for all arms to complete
- Then proceeds to save-state

**Refinery Patrol:**
- Less common (sequential processing), but useful for parallel test runs

## Relationship to gate

This is a variant of gate where the condition is "all children complete" rather than
an arbitrary expression. Could be implemented as:

    gate:
      condition: "children-of(survey-workers).all(status == complete)"

But dedicated syntax is cleaner for this common pattern.

## Dependencies

- Depends on gt-8tmz.8 (for-each creates the children)
- Depends on gt-8tmz.4 (gate infrastructure)

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


Update Deacon template to emphasize staying in ~/gt/deacon directory

The Deacon template should instruct the agent to stay in ~/gt/deacon/ as much as possible, and always return there after any excursion. This prevents issues with identity detection (mail, mol status) which depend on cwd.


Add gate checking to Deacon patrol loop

Integrate gate checking into Deacon's patrol cycle.

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

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

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

    }
}

Human escalation path design

Flesh out the human escalation mechanism for Gas Town errors. Currently: errors mail Mayor, Mayor startup prompts about escalations. Need: structured escalation channel, escalation severity levels, and clear documentation. All edge cases in molecular algebra can write warnings to this channel.


Add gt hook command (wrapper for bd hook)

Add a thin wrapper command `gt hook` that calls `bd hook` to inspect what's pinned to an agent's hook.

## Usage

```bash
gt hook                    # Show what's on current agent's hook
gt hook --agent deacon     # Show Deacon's hook
gt hook --agent gastown/furiosa  # Show polecat's hook
```

## Implementation

Thin wrapper in gt that:
1. Determines current agent identity
2. Calls `bd hook [--agent <name>]`
3. Formats output for gt context

## Why gt wrapper?

- Consistent with gt ecosystem (gt mail, gt status, etc.)
- Can add gt-specific context (session status, etc.)
- Easier discovery for gt users

Mail orchestrator daemon

Background mail orchestrator daemon.

## Command
```
gt mail orchestrate [--interval N] [--once] [--verbose]
```

## Purpose
Background process that:
1. Monitors outbox for pending mail
2. Delivers to recipient inboxes
3. Handles offline recipients (retry later)
4. Cleans delivered messages from outbox

## Why Needed?
Current mail is synchronous. If recipient is offline or mailbox locked, send fails.
Orchestrator enables async delivery with retry.

## Implementation
```go
func (o *Orchestrator) Run(interval time.Duration) error {
    ticker := time.NewTicker(interval)
    for range ticker.C {
        o.processOutbox()
    }
}

func (o *Orchestrator) processOutbox() {
    // List outbox/*.json
    // For each, attempt delivery
    // On success, delete from outbox
    // On failure, increment retry count
}
```

## Outbox Structure
```
<town>/mayor/mail/outbox/
├── msg-abc123.json
└── msg-def456.json
```

## Lower Priority
Current synchronous delivery works. Orchestrator is optimization.

## Acceptance Criteria
- [ ] Background daemon mode
- [ ] Retry failed deliveries
- [ ] --once for single pass
- [ ] Configurable interval


Design: Failure modes and recovery

Document failure modes and recovery strategies for Gas Town operations.

## Critical Failure Modes

### 1. Agent Crash Mid-Operation

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

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

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

### 2. Git State Corruption

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

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

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

### 3. Beads Sync Conflict

**Scenario**: Two polecats modify same issue

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

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

### 4. Tmux Failure

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

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

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

### 5. Claude API Issues

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

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

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

### 6. Disk Full

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

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

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

### 7. Network Failure

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

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

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

## Recovery Principles

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

## Implementation

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


Create activity aggregator

Component that connects to multiple rig beads daemons and merges their activity into a unified view. Polls GetMutations and GetWorkerStatus from each rig, groups by rig/worker. Handles connection failures gracefully.

BLOCKED BY (Beads rig):
- bd-gqxd: Enrich MutationEvent with title and assignee
- bd-l13p: Add GetWorkerStatus RPC endpoint
- bd-0oqz: Add GetMoleculeProgress RPC endpoint


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.


Test shiny formula end-to-end

Test the shiny (engineer-in-box) formula:

1. **Create issue with formula**:
```bash
gt sling shiny --var feature="Add hello world endpoint" gastown
```

2. **Watch polecat execute shiny steps**:
   - design: Architecture thinking
   - implement: Write the code
   - review: Self-review
   - test: Run tests
   - submit: Create PR

3. **Verify output**:
   - Design notes in issue/commit
   - Implementation matches design
   - Tests pass
   - PR created and ready for merge

Success: A reviewed, tested PR from a single command.

Startup hooks nudge Deacon

When a new Claude session starts (via startup hook), it should nudge Deacon so Deacon knows a new agent has appeared. This is one of Deacons extra wake sources for GUPP backstop.

Implementation: Add gt nudge deacon session-started to the startup hook chain.


Implement shared beads architecture for rig

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

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

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

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

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


gt doctor: add Claude settings.json validation

Add a new doctor check to validate Claude Code settings in worker directories:

**Check for:**
1. .claude/settings.json exists in polecats/*, crew/*, witness/rig, refinery/rig
2. SessionStart hook has 'gt prime' command
3. Autonomous roles (polecat, witness, refinery) have 'gt mail check --inject' in SessionStart
4. Interactive roles (crew, mayor) have mail check in UserPromptSubmit only

**Auto-fix capability:**
Use internal/claude.EnsureSettingsForRole() to create missing settings files.

Context: The spawn priming race condition fix (gt-6957) added embedded settings templates. Doctor should validate these are in place.

gt spawn: Notify Deacon and Witness on polecat start

When gt spawn creates a polecat, it should mail both Deacon and Witness:

```
gt mail send <rig>/witness -s 'POLECAT_STARTED furiosa' -m 'Issue: gt-xxx'
gt mail send deacon/ -s 'POLECAT_STARTED gastown/furiosa' -m 'Issue: gt-xxx'
```

This enables:
- Witness to bond a lease to its patrol wisp
- Deacon to verify worker started (redundancy)
- Both to nudge if worker is idle at prompt

Part of the village self-monitoring architecture.

Define Engineer as the Refinery agent role

Clarify the distinction:

  - `gt refinery start/stop/status` commands
  - tmux session name: `refinery` or `<rig>-refinery`

- **Engineer** = role/agent who works in the Refinery
  - CLAUDE.md prompting: "You are an Engineer..."
  - Documentation: "The Engineer processes merge requests..."
  - Mail address: `<rig>/engineer` (or `<rig>/refinery`?)

Updates needed:
- Add Engineer role description to docs
- Update CLAUDE.md templates for refinery agents
- Keep `gt refinery` commands as-is (they manage the place)
- Internal code stays `internal/refinery/` (the module)

Patrol agent state.json not updated on activity

Witness and Refinery state.json files show last_active from Dec 19 even though sessions have been running. The state should update each patrol cycle.

Evidence:
```
$ cat beads/witness/state.json
{"role": "witness", "last_active": "2025-12-19T17:50:00Z"}

$ cat beads/refinery/state.json
{"role": "refinery", "last_active": "2025-12-19T17:50:00Z"}
```

Expected: last_active should update each time the agent runs a patrol cycle.

Impact: Can't tell if patrol agents are actually active vs just having an open tmux session.

gt nudge should accept partial/fuzzy session names

Currently gt nudge requires the exact tmux session name (e.g., gt-gastown-crew-max). Should be more forgiving:

1. Accept partial matches when unambiguous (e.g., 'max' → gt-gastown-crew-max)
2. Accept shorthand like 'gastown/max' or 'crew/max'
3. Show helpful error with suggestions when ambiguous

Examples that should work:
- gt nudge max '...' → matches gt-gastown-crew-max
- gt nudge gastown/max '...' → matches gt-gastown-crew-max
- gt nudge beads-dave '...' → matches gt-beads-crew-dave

ZFC #10: Polecat reports cleanup status instead of Go checking git

**ZFC Violation:** internal/polecat/manager.go:192-215

Go examines git state to decide if polecat removal is safe:
```go
status, err := polecatGit.CheckUncommittedWork()
if status.StashCount > 0 || status.UnpushedCommits > 0 {
    return &UncommittedWorkError{...}
}
```

**ZFC-compliant solution:**
Polecat reports its own cleanup status via agent bead:
- state: stopped
- cleanup_status: clean | has_uncommitted | has_stash | has_unpushed
- Witness reads cleanup_status before calling nuke
- Polecat is authority on whether it's safe to remove

**Relates to:** Day 4.1/4.2 (recycle/nuke commands)

gt mail send should tmux-notify recipient

## Problem

When mail is sent via gt mail send, the recipient session does not get a tmux notification. In Python Gas Town (PGT), mail delivery triggers a tmux display-message or similar notification so the agent knows mail arrived.

## Expected Behavior

When gt mail send <addr> is called:
1. Mail is delivered to recipient inbox
2. If recipient has an active tmux session, send notification
3. Notification should be visible (display-message or bell)

## Current Behavior

Mail is delivered but no notification. Agent has to poll inbox to discover new mail.

## Impact

- Agents miss time-sensitive messages
- Heartbeat pokes from daemon will not wake agents
- Coordination is slower (polling vs push)

## Implementation Notes

After successful mail delivery, check if recipient has active session:
- gt session list can identify active sessions
- tmux display-message or send-keys can notify
- Could inject a visible prompt like "[MAIL] New message from <sender>"

## Reference

Check PGT implementation for how it handles this.

Epic: Patrol parity - Witness and Refinery match Deacon sophistication

Bring Witness and Refinery patrols up to Deacon's level of sophistication.

## Deacon has
1. Defined patrol molecule with clear steps
2. Wisp-based execution (spawn, run, squash, loop)
3. Daemon monitoring with auto-nudge on naked state
4. Handoff bead attachment mechanism
5. Banners for observability
6. Context-aware loop-or-exit

## Children
- gt-h1n5: Witness patrol: Add banners and wisp-based execution
- gt-qz2l: Refinery patrol: Add banners and wisp-based execution
- gt-poxd: Create handoff beads for Witness and Refinery roles

## Success criteria
- Tailing a Witness or Refinery session shows clear banners
- Patrols spawn as wisps and squash to digests
- Each role has a handoff bead with attached_molecule
- Daemon monitors Witness/Refinery nakedness (stretch goal)


Update refinery to read local branches

Refinery manager needs to access polecat branches locally instead of fetching from origin.

## Changes

- internal/refinery/engineer.go - local branch access
- Remove DeleteRemoteBranch calls (branches are local now)
- Update merge workflow to work with local refs

## Key insight
All worktrees share the same .git - refinery can see polecat/nux branch directly.

Activity feed from wisp state: gt patrol status

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

## Problem

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

## Desired Commands

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

## Data Sources

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

## Use Cases

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

Activity feed improvements

Make the activity feed (gt feed) a first-class TUI experience using charmbracelet.

## Vision

A real-time dashboard showing all Gas Town activity with:
- Agent tree organized by role (mayor, witnesses, crew, polecats)
- Live event stream
- Vim-style navigation
- Filtering and search

## Architecture

Two-tier event system:
- ~/gt/.events.jsonl (raw, audit) - all events from gt, bd, agents
- Feed daemon curates → ~/gt/.feed.jsonl (user-facing) - filtered, deduped

TUI reads from curated feed for smooth UX.

## Layout (Dashboard + Stream)

## Key Features
1. Real-time updates - events stream in live
2. Agent tree - all agents grouped by role with status
3. Vim-style navigation - j/k, gg/G, /search
4. Filtering - by rig, role, event type, time
5. Collapsible sections
6. Details on select

## Tech Stack
- bubbletea - TUI framework
- bubbles - viewport, list components
- lipgloss - styling (already have)

## Success Criteria
- Feed is beautiful and scannable at a glance
- Agent activity visible in real-time
- Works in any terminal, degrades gracefully for pipes

ZFC #4: Replace daemon identity parsing with agent self-registration

**ZFC Violation:** internal/daemon/lifecycle.go:209-309

The daemon has embedded switch statements that parse agent identity strings to determine:
- Session names
- Working directories
- Which agents need pre-sync
- Restart commands

**Current anti-pattern:**
```go
if strings.HasSuffix(identity, "-refinery") {
    needsPreSync = true
    workDir = filepath.Join(...)
}
```

**ZFC-compliant solution:**
Agent types self-register via role beads:
- Role bead contains: working_dir, session_name_pattern, needs_sync, restart_command
- Daemon reads role bead to get lifecycle config
- No identity string parsing in Go

**Depends on:** Day 1.5 (role beads exist)

Outpost error handling: Retry logic and resilience

## Overview

Error handling and retry logic for outpost operations.

## Error Types

```go
var (
    ErrOutpostUnreachable = errors.New("outpost unreachable")
    ErrWorkerSpawnFailed  = errors.New("worker spawn failed")
    ErrWorkerTimeout      = errors.New("worker timed out")
    ErrCostCapExceeded    = errors.New("cost cap exceeded")
    ErrAllOutpostsBusy    = errors.New("all outposts at capacity")
)
```

## Retry Policy

```go
type RetryPolicy struct {
    MaxAttempts     int
    InitialBackoff  time.Duration
    MaxBackoff      time.Duration
    BackoffFactor   float64
    RetryableErrors []error
}

func DefaultRetryPolicy() *RetryPolicy {
    return &RetryPolicy{
        MaxAttempts:    3,
        InitialBackoff: 1 * time.Second,
        MaxBackoff:     30 * time.Second,
        BackoffFactor:  2.0,
        RetryableErrors: []error{
            ErrOutpostUnreachable,
            ErrWorkerSpawnFailed,
        },
    }
}
```

## Retry Implementation

```go
func (m *OutpostManager) SpawnWithRetry(issue string, cfg WorkerConfig) (Worker, error) {
    var lastErr error
    backoff := m.retryPolicy.InitialBackoff

    for attempt := 0; attempt < m.retryPolicy.MaxAttempts; attempt++ {
        outpost := m.policy.SelectOutpost(issue, m.outposts)
        if outpost == nil {
            return nil, ErrAllOutpostsBusy
        }

        worker, err := outpost.Spawn(issue, cfg)
        if err == nil {
            return worker, nil
        }

        if !m.isRetryable(err) {
            return nil, err
        }

        lastErr = err
        time.Sleep(backoff)
        backoff = min(backoff * m.retryPolicy.BackoffFactor, m.retryPolicy.MaxBackoff)
    }

    return nil, fmt.Errorf("spawn failed after %d attempts: %w",
        m.retryPolicy.MaxAttempts, lastErr)
}
```

## Outpost Health Tracking

```go
type OutpostHealth struct {
    LastPing      time.Time
    LastError     error
    FailureCount  int
    CircuitBreaker bool  // If true, skip this outpost
}

func (m *OutpostManager) updateHealth(name string, err error) {
    // Track failures, open circuit breaker after N failures
    // Auto-reset after successful ping
}
```

## Config

```yaml
policy:
  retry:
    max_attempts: 3
    initial_backoff: 1s
    max_backoff: 30s

  circuit_breaker:
    failure_threshold: 5
    reset_timeout: 1m
```

Witness patrol wisp with polecat leases

Witness should maintain a rolling patrol wisp that tracks active polecats:

```
wisp-witness-patrol
├── lease: furiosa (boot → working → done)
├── lease: nux (working)
└── lease: slit (done, closed)
```

When POLECAT_STARTED arrives:
- bd mol bond mol-polecat-lease wisp-patrol --var polecat=X

Patrol loop iterates leases:
- gt peek $polecat
- If idle: gt nudge
- If shutdown received: close lease

When all leases closed:
- bd mol squash wisp-xxx --summary='N polecats processed'

Requires mol-polecat-lease proto definition.

Patrol cycle 12: All healthy


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.

Unify gt sling and gt spawn with --args support

## Summary

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

## Current State (Partially Done)

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

## Remaining Work

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

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

### 2. Remove top-level gt spawn

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

### 3. Unified UX Design

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

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

### 4. Update Witness/Refinery/Deacon

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

## Acceptance Criteria

- [ ] All spawn flags available in sling
- [ ] `gt spawn` removed (or hidden/deprecated)
- [ ] Witness uses `gt sling <rig>` for polecat work
- [ ] Docs updated
- [ ] Both human and agent UX is clean

@group dynamic resolution in mail router

## @group Dynamic Resolution in Mail Router

Wire agent bead queries into mail router for @group addresses.

## Updated Approach (post agent-as-bead + Dogs)

Agent discovery uses bead queries:

```bash
bd list --type=agent --rig=gastown         # All agents in rig
bd list --type=agent --role_type=witness   # All witnesses
bd list --type=agent --role_type=dog       # All dogs
```

## Supported Patterns

| Pattern | Resolution | Scope |
|---------|------------|-------|
| `@rig/gastown` | `--rig=gastown` | All gastown agents |
| `@town` | `--rig=""` (no filter) | All town-level agents |
| `@witnesses` | `--role_type=witness` | All witnesses across rigs |
| `@crew/gastown` | `--role_type=crew --rig=gastown` | Gastown crew |
| `@dogs` | `--role_type=dog` | All Deacon dogs |
| `@overseer` | Special case (not bead query) | Human operator |

## Deliverables

1. Parse @group syntax in router
2. Resolve via `bd list --type=agent` queries
3. Fan-out at send time (N copies, one per recipient)
4. Special handling for `@overseer` (single recipient, uses overseer.json)

## @overseer Special Case

The overseer is the human operator - NOT an agent bead. Resolution:
- Load `mayor/overseer.json`
- Use `overseer/` as recipient address
- No bead query needed

## Dependencies
- Agent bead schema (gt-ikyo1) ✅ closed
- Dog agent beads need role_type=dog (new prereq)

## Acceptance
- @rig/gastown sends to all gastown agents
- @dogs sends to all Deacon dogs
- @overseer sends to human operator
- Each recipient gets own message copy

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

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

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

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

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

This should be standard Gas Town rig configuration.


gt sling pinToHook doesn't set pinned boolean field

## Updated Root Cause Analysis (2025-12-23)

The issue is **NOT** in gt as originally thought. It's in the beads (bd) codebase.

### What happens:
1. `bd pin` correctly sets pinned=1 in SQLite
2. Any subsequent `bd` command (even `bd show`) resets pinned to 0
3. This happens even with `--no-auto-import` and `--sandbox` flags

### Evidence:
```bash
$ bd --no-daemon pin gt-k08o --for=max
📌 Pinned gt-k08o to max's hook

$ sqlite3 beads.db 'SELECT id, pinned FROM issues WHERE id="gt-k08o"'
gt-k08o|1   # ← Correct immediately after pin

$ bd --no-daemon --no-auto-import show gt-k08o
[shows issue without pinned field]

$ sqlite3 beads.db 'SELECT id, pinned FROM issues WHERE id="gt-k08o"'
gt-k08o|0   # ← WRONG\! bd show overwrote it
```

### Where to look:
The bug is likely in one of these beads code paths:
- Some import/hydration running despite --no-auto-import
- WAL mode not flushing before subsequent reads
- Multi-repo or redirect handling corrupting pinned field

### Workaround:
The handoff bead attachment mechanism (AttachMolecule) works correctly.
The pinned field is cosmetic for `bd hook` visibility only.
gt sling correctly uses AttachMolecule for work assignment.

### Next steps:
Create a beads issue to fix this properly in the bd codebase.
This is not a gt issue.

gt rig reset --stale: Clear orphaned in_progress items

Reset in_progress issues when their assigned agent no longer exists.

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

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

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

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

gt polecat done should auto-stop running session

Currently 'gt polecat done' fails if session is running, requiring a separate 'gt session stop' first. This is unnecessary friction - done should just stop the session automatically since that's always what you want.


gt mail: Cross-level routing is broken

When Mayor sends mail to rig worker, message lands in wrong beads database. Sender's beads vs recipient's.


Conditional aspects (feature flags)

Apply aspects conditionally based on environment or config. Example: apply security-audit only when env.SECURITY_SCANNING == enabled. Adds 'when' clause to aspect composition.


attached_args: Refactor runStart into focused helper functions

Break up the 126-line runStart function in start.go.

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

## Current structure (lines 129-255)
runStart does:
1. Crew path detection
2. Workspace verification
3. Mayor session start
4. Deacon session start
5. Optional rig agent startup
6. Configured crew auto-start

## Refactoring plan
Extract these helpers:
```go
func startMayorSession(townRoot string, verbose bool) error
func startDeaconSession(townRoot string) error
func startRigAgents(townRoot string, rigs []string) error
func startConfiguredCrew(townRoot string, config *TownConfig) error
```

## Acceptance criteria
- [ ] runStart reduced to <50 lines
- [ ] 4 helper functions extracted
- [ ] Each helper is <40 lines
- [ ] No change in behavior
- [ ] go test ./internal/cmd/... passes
- [ ] Manual test: gt start works correctly


Self-mail should suppress tmux notification

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

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

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


detectSender() doesn't recognize crew workers

## Problem

detectSender() in internal/cmd/mail.go only checks for /polecats/ directories. Crew workers in /crew/<name>/ fall through to the default 'mayor/', so:
- gt mail inbox shows mayor's inbox instead of the crew worker's
- gt mail send sets the wrong From address

## Fix

Add crew worker detection before the /polecats/ check:

if strings.Contains(cwd, "/crew/") {
    parts := strings.Split(cwd, "/crew/")
    ...
    return fmt.Sprintf("%s/crew/%s", rigName, crewMember)
}

## Affected
- Any crew worker running gt mail inbox without explicit address
- Crew worker handoffs (wrong sender)


Add neighbor-check steps to all patrol molecules

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

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

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

This creates distributed monitoring - no single point of failure.

mol-polecat-arm

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.

## Variables

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

## Steps

### capture
Capture recent tmux output for this polecat.

```bash
tmux capture-pane -t gt-{{rig}}-{{polecat_name}} -p | tail -50
```

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

### assess
Categorize polecat state.

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

### load-history
Read nudge history for this polecat from patrol state.

```
nudge_count = state.nudges[{{polecat_name}}].count
last_nudge_time = state.nudges[{{polecat_name}}].timestamp
```

Needs: assess

### decide
Apply the nudge matrix to determine action.

| 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

### execute
Take the decided action.

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

**pre-kill-verify**:
```bash
cd polecats/{{polecat_name}}
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: {{polecat_name}} 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

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

Phase 2.3: Polecat CLAUDE.md molecule workflow protocol

Update polecat prompting for molecule-based work.

## CLAUDE.md Updates

Add section on molecule workflow:

```markdown
## Molecule Workflow

When assigned a molecule (check gt prime output):

1. Follow molecule steps in order
2. Mark steps complete: bd mol step complete <step-id>
3. Before signaling done:
   a. Generate summary of work performed
   b. Run: bd squash <molecule-root> --summary "<your summary>"
4. Then signal done as normal

### Summary Guidelines

Your summary should include:
- What was the task?
- What did you do?
- What was the outcome?
- Any issues or follow-ups?

Keep it to 2-4 sentences. This becomes the permanent record.

Polecat wisp architecture: Proto → Wisp → Mol pattern

Design the three-layer architecture for polecat lifecycle:

## The Insight

Polecats should run a ONE-SHOT WISP (not looping like patrols):

**Step 1: Onboard**
- Read full polecat protocol (polecat.md template)
- Learn Gas Town operation, exit strategies, molecule protocol
- This is the 'how to be a polecat' education

**Step 2: Execute Mol**
- Run the assigned molecule (the actual work item)
- Could span multiple sessions via session continuity
- The mol is pure work content (epic, issue, feature)

**Step 3: Cleanup**
- Run final step of the wisp
- Self-delete / request shutdown

## Three Layers

- **Proto**: polecat.md template (instructions for being a polecat)
- **Wisp**: One-shot harness instantiated from proto (wraps the mol)
- **Mol**: The work item (issue/epic being processed)

## Why This Matters

1. **Separation of concerns**: Protocol (how) vs Work (what)
2. **Reusability**: Same wisp harness wraps any mol
3. **Extensibility**: Plugin points for custom behavior
4. **Session continuity**: Wisp handles multi-session, not the mol
5. **Blurred control/data planes**: Intentional in Gas Town

## Design Questions

1. How does proto (polecat.md) become a wisp instance?
2. What are the plugin/extension points?
3. Should all 'engineer in a box' mols use proto → wisp → mol?
4. How does this relate to refinery/deacon patterns?
