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

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

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


Swarm: ephemeral rig support

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


Update templates for Propulsion Principle

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

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

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

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

Polecat name pooling: Bounded reusable names

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

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

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

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

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


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.

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
}
```

File locking for concurrent access

Add file locking for concurrent access safety.

## At-Risk Files
- .gastown/swarms.json (or per-swarm state.json)
- .gastown/refinery.json
- polecats/<name>/state.json
- inbox.jsonl files

## Go File Locking
Use syscall.Flock for advisory locking:
```go
type FileLock struct {
    file *os.File
}

func AcquireLock(path string, timeout time.Duration) (*FileLock, error) {
    f, err := os.OpenFile(path+".lock", os.O_CREATE|os.O_RDWR, 0644)
    if err != nil {
        return nil, err
    }
    // Use syscall.Flock with timeout
}

func (l *FileLock) Release() error
```

## Integration Pattern
```go
func (m *Manager) saveState(ref *Refinery) error {
    lock, err := AcquireLock(m.stateFile(), 5*time.Second)
    if err != nil {
        return fmt.Errorf("could not acquire lock: %w", err)
    }
    defer lock.Release()

    // Read-modify-write cycle
}
```

## New Package
internal/filelock/
├── lock.go     # FileLock, AcquireLock
└── lock_test.go

## Apply To
- internal/refinery/manager.go: loadState/saveState
- internal/cmd/swarm.go: SwarmStore
- internal/mail/mailbox.go: Append, rewrite
- internal/polecat/manager.go: state operations

## Timeout Handling
Default 5 second timeout. Return error if lock not acquired.

## Acceptance Criteria
- [ ] Lock files created (.lock extension)
- [ ] Timeout on lock contention
- [ ] All state files protected
- [ ] Locks released on error paths


Worker prompting: Beads write access

Add beads write access section to polecat AGENTS.md.template.

## Beads Access Section for Prompting

```markdown
## Beads Access

You have **full beads access** - create, update, and close issues.

### Quick Reference

```bash
# View work
bd ready                    # Issues ready (no blockers)
bd list                     # All open issues
bd show <id>                # Issue details

# Create issues
bd create --title="Fix bug" --type=bug --priority=2
bd create --title="Add feature" --type=feature

# Update issues
bd update <id> --status=in_progress    # Claim work
bd close <id>                          # Mark complete

# Sync (required before merge!)
bd sync                     # Commit beads changes to git
```

### When to Create Issues

Create beads issues when you discover work that:
- Is outside your current task scope
- Would benefit from tracking
- Should be done by someone else

**Good examples**:
```bash
bd create --title="Race condition in auth" --type=bug --priority=1
bd create --title="Document API rate limits" --type=task --priority=3
```

**Don't create for**:
- Tiny fixes you can do in 2 minutes
- Vague "improvements" with no scope
- Work already tracked elsewhere

### Beads Sync Protocol

**CRITICAL**: Always sync beads before merging!

```bash
bd sync                    # Commits beads changes
git add .beads/
git commit -m "beads: sync"
```

If you forget to sync, beads changes are lost when session ends.
```

## Implementation

Add to AGENTS.md.template polecat section.

Ephemeral polecats: spawn fresh, delete on completion

## Design Decision

Switch from pooled/idle polecats to ephemeral model:
- Spawn creates fresh worktree from main
- Polecat requests shutdown when done (bottom-up)
- Witness verifies handoff, kills session, deletes worktree
- No 'idle' state - polecats exist only while working

## Rationale

1. **Git worktrees are fast** - pooling optimization is obsolete
2. **Pooling creates maintenance burden:**
   - Git stashes accumulate
   - Untracked artifacts pile up
   - Branches drift from main
   - Beads DB gets stale
3. **PGT sync problems** came from persistent branches
4. **Support infrastructure exists** - Witness, Refinery, Mayor handle continuity
5. **Simpler mental model** - polecat exists = work in progress

## Lifecycle

```
Spawn:
  gt spawn --issue <id>
  → Creates fresh worktree: git worktree add polecats/<name> -b polecat/<name>
  → Initializes beads in worktree
  → Starts session, assigns work

Working:
  Polecat does task
  → Pushes to polecat/<name> branch
  → Submits to merge queue when ready

Completion (POLECAT-INITIATED):
  Polecat runs: gt handoff
  → Verifies git state clean
  → Sends mail to Witness: "Ready for shutdown"
  → Marks itself done, waits for termination

Cleanup (WITNESS-OWNED):
  Witness receives shutdown request
  → Verifies PR merged or in queue
  → Verifies no uncommitted changes
  → Kills session: gt session stop <rig>/<polecat>
  → Deletes worktree: git worktree remove polecats/<name>
  → Deletes branch: git branch -d polecat/<name>
  → Optionally: Notifies Mayor of completion
```

## Key Insight: Bottom-Up Shutdown

**Old model (wrong)**: Top-down batch shutdown - "cancel the swarm"
**New model (right)**: Bottom-up individual shutdown - polecat requests, Witness executes

This enables streaming:
- Workers come and go continuously
- No "swarm end" to trigger cleanup
- Each worker manages its own lifecycle
- Witness is the lifecycle authority

## Implementation

1. Add `gt handoff` command for polecats to request shutdown
2. Modify gt spawn to always create fresh worktree
3. Run bd init in new worktree (beads needs initialization)
4. Add shutdown request handler to Witness
5. Witness verifies handoff, then cleans up:
   - Kill session
   - Remove worktree
   - Delete branch
6. Remove 'idle' state from polecat state machine
7. Simplify gt polecat list (only shows active)

## Impact on Other Tasks

- gt-17r (Zombie cleanup): Becomes trivial - orphan worktrees
- gt-4my (Worker health): Simpler - no idle/stuck ambiguity
- gt-f9x.5/f9x.6 (Doctor): Fewer states to validate
- gt-eu9 (Witness handoff): Witness receives polecat shutdown requests


Engineer session restart protocol

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

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

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


Support numeric shortcuts in mail read (e.g., 'mail read 1')

When inbox shows numbered messages like:
* 1. gm-19b29031...  2025-12-16  mayor  Subject...
* 2. gm-19b26d51...  2025-12-16         Subject...

Users should be able to run 'gt mail read 1' instead of needing the full message ID 'gt mail read gm-19b29031f6a172206'.

Implementation:
- Track inbox message order in display
- Map numeric indices to actual message IDs
- Accept both numeric shortcuts and full IDs in 'mail read' command


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

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

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

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


gt molecule seed: create built-in molecules as beads

The molecule infrastructure is complete but built-in molecules (engineer-in-box, quick-fix, research) need to be seeded into the beads database.

## Current State
- `gt molecule list` works but shows 0 molecules
- BuiltinMolecules() in internal/beads/builtin_molecules.go has 3 molecules defined
- No way to create them as beads

## Needed
Add `gt molecule seed` command that:
1. Reads BuiltinMolecules()
2. Creates each as a bead with type: molecule
3. Uses well-known IDs (mol-engineer-in-box, mol-quick-fix, mol-research)
4. Idempotent (skip if already exists)

## Acceptance Criteria
```
gt molecule seed
gt molecule list   # Shows 3 built-in molecules
```

## Parent

gt mq reject: manual MR rejection

Implement 'gt mq reject <id> --reason "..."' for manual rejection.

Actions:
1. Verify MR exists and is open
2. Close MR with close_reason=rejected
3. Notify worker via mail (optional)
4. Do NOT close source issue (work not done)

Options:
- --reason REASON: required explanation
- --notify: send mail to worker

Reference: docs/merge-queue-design.md#cli-commands


Slim down rig root config.json to identity only

Rig root config.json should only contain identity:
- type, version, name, git_url, beads.prefix, created_at
- Remove any behavioral config (move to settings/config.json)
- Update RigConfig type to separate identity from settings
- Ensure loader reads identity from root, settings from settings/


Deacon marching orders: pinned bead with rounds molecule

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

## Concept

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

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

## Pinned Bead Structure

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

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

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

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

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

## Reading Marching Orders

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

## Updating the Kernel

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

## Bootstrap

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

bd ready --type: missing type filter for MQ integration

bd ready lacks --type flag that engineer.go expects.

## Code (internal/refinery/engineer.go)
readyMRs, err := e.beads.ReadyWithType("merge-request")

## Actual bd ready
No --type flag - only supports assignee, label, priority filters.

## Impact
Refinery can't find merge-requests in queue, so MQ doesn't process anything.

## Fix Options
1. Add --type flag to bd ready
2. Use bd list --type=merge-request --status=open instead
3. Both (ready filters for unblocked, list for all)

This is blocking the entire MQ pipeline.


Add human escalation configuration

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

Implement handoffs using pinned beads

Replace the current mail-based handoff system with pinned beads.

## Current Problem

Handoff messages get closed before the successor can read them because:
1. `gt mail read` auto-acks (closes) messages
2. `bd mail inbox` only shows open messages
3. Successor sees empty inbox

## Solution

Use pinned beads for handoffs:
- One pinned bead per role: `mayor-handoff`, `<rig>-refinery-handoff`, etc.
- Predecessor updates the content before cycling
- Successor reads on startup via `gt prime`
- Never closes - always available

## Implementation

### 1. Create handoff beads on first cycle
- `bd create --title='Mayor Handoff' --type=task --status=pinned --assignee=mayor`
- Store ID in role config or use well-known naming convention

### 2. Update gt handoff command
- Instead of `bd mail send`, update the pinned handoff bead
- `bd update <handoff-id> --description='...handoff content...'`

### 3. Update gt prime
- Read the role's handoff bead
- Display content to successor

### 4. Compression/reset
- `gt rig reset` clears handoff content
- Or manual: `bd update <handoff-id> --description=''`

## Dependencies

Requires beads-6v2 (StatusPinned) to be implemented first.

Session pre-shutdown checks

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

## Pre-Shutdown Checks

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

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

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

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

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

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

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

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

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

Polecat CLAUDE.md: configure auto-approve for bd and gt commands

Polecats get stuck waiting for bash command approval when running
bd and gt commands. Need to configure Claude Code to auto-approve these.

Options:
1. Add allowedTools to polecat CLAUDE.md
2. Configure .claude/settings.json in polecat directory
3. Use --dangerously-skip-permissions flag (not recommended)

Should auto-approve:
- bd (beads commands)
- gt (gastown commands)
- go build/test
- git status/add/commit/push

Should still require approval:
- rm -rf
- Arbitrary commands outside project

Related to polecat prompting (gt-e1y, gt-sd6).


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.

Hook system for event extensibility

GGT needs hook system for extensibility like PGT.

## Event Types
```go
type Event string
const (
    EventPreSessionStart  Event = "pre-session-start"
    EventPostSessionStart Event = "post-session-start"
    EventPreShutdown      Event = "pre-shutdown"
    EventPostShutdown     Event = "post-shutdown"
    EventOnPaneOutput     Event = "on-pane-output"
    EventSessionIdle      Event = "session-idle"
    EventMailReceived     Event = "mail-received"
    EventWorkAssigned     Event = "work-assigned"
)
```

## Hook Configuration

    ],
    "on-pane-output": [
      {"type": "command", "cmd": "./scripts/activity-monitor.sh"}
    ]
  }
}
```

## Hook Types
1. **Command**: Execute external script
2. **Built-in**: Internal Go functions (pre-shutdown checks)

## Hook Interface
```go
type HookRunner struct {
    config *HookConfig
}

type HookResult struct {
    Success bool
    Message string
    Block   bool  // For pre-* hooks: should operation be blocked?
}

Swarm learning: Session cleanup missing from swarm workflow

## Problem

After Enders Game swarm completed (18 issues merged), 16 polecat sessions were left running but idle. No automated cleanup occurred.

## What Should Happen

1. Witness detects polecat completed work (idle at prompt)
2. Witness verifies git state is clean
3. Witness shuts down session
4. Witness reports completion to Mayor

## GGT Components

- gt-cxx: Witness context cycling (covers self-cycling)
- gt-u1j.9: Witness daemon heartbeat loop
- gt-kmn.6: Witness swarm landing protocol

## Recommendation

Add to Witness responsibilities:
- Monitor for 'work complete' signals (DONE keyword, idle detection)
- Automated session shutdown after verification
- Swarm completion reporting to Mayor

See also: architecture.md 'Worker Cleanup (Witness-Owned)' section which describes this but it wasn't implemented in PGT.


Crew workers: design documentation and remaining work

## Summary

Crew workers are user-managed persistent workspaces within a rig, distinct from polecats.

## Current Implementation

### Commands (all working)
- `gt crew add <name>` - Create workspace (git clone)
- `gt crew list` - List workspaces with status
- `gt crew at <name>` - Attach to tmux session
- `gt crew remove <name>` - Remove workspace
- `gt crew pristine [<name>]` - git pull + bd sync
- `gt crew refresh <name>` - Context cycle with handoff mail
- `gt crew status [<name>]` - Detailed status
- `gt crew rename <name>` - Rename workspace

### Crew vs Polecat

| Aspect | Crew | Polecat |
|--------|------|---------|
| Lifecycle | User-managed | Witness-managed |
| Scheduling | Manual | `gt spawn` |
| Merge flow | Direct push OK | Integration branch → refinery |
| Garbage collection | Never | Auto on completion |
| Identity | Long-lived (emma, dave) | Ephemeral (Nux, Toast) |

## Known Bugs

- **gt-70b3**: detectSender() doesn't recognize crew workers
- **gt-vdp0**: Crew CLAUDE.md shows Refinery template

## Potential Enhancements

1. Rebase helper in `gt crew pristine` for conflict resolution
2. Cross-rig crew support (crew worker in multiple rigs?)
3. Better mail identity auto-detection for crew


load-context

Run gt prime and bd prime. Verify issue assignment.
Check inbox for any relevant messages.

Read the assigned issue ({{issue}}) and understand the requirements.
Identify any blockers or missing information.


Add harness overview to Mayor priming

Update gt prime Mayor context to explain the harness concept: umbrella repo for GT installation, rigs underneath, Mayor sits above all rigs


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


Success handling: close MR, close source issue, cleanup

Handle successful merge completion.

Steps:
1. Update MR with merge_commit SHA:
   bd update <id> --body='...\nmerge_commit: <sha>'
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

Configuration:
- delete_merged_branches: bool (default true)

Preflight molecule: verify baseline health before work

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

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

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

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

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

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


gt session restart/status: Complete session management

Add missing session subcommands:

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

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

gt doctor: detect orphaned code on beads-sync branch

After merging beads-sync to main, some code changes can be lost if the merge conflict resolution drops files.

Add a doctor check that runs:
  git diff main..beads-sync -- '*.go' '*.md'

If there are differences in code files (not just .beads/), warn about potentially orphaned work.

Today's incident: Merge 96c773f lost mailbox.go and router.go changes from 5791752, requiring re-implementation.

Acceptance:
- gt doctor warns if beads-sync has unmerged code changes
- Excludes .beads/ directory (expected to differ)
- Shows file list of orphaned changes


orphan-check

Find abandoned work. Check for in_progress issues with no active agent.


Plugin surface for daemon lifecycle hooks

Allow rigs to customize daemon behavior via hooks/plugins.

## Hook Points

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

## Configuration

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

## Signal Contribution

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

## Use Cases

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


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).
