Overseer Crew: User-managed persistent workspaces

## Overview

Crew workers are the overseer's (human's) personal workspaces within a rig. Unlike polecats which are witness-managed and ephemeral, crew workers are:

- **Persistent**: Not auto-garbage-collected
- **User-managed**: Overseer controls lifecycle
- **Long-lived identities**: dave, emma, fred - recognizable names
- **Gas Town integrated**: Mail, handoff mechanics work
- **Tmux optional**: Can work in terminal directly

## Directory Structure

```
<rig>/
  polecats/       # Managed workers (witness controls)
  refinery/       # Merge queue processor
  witness/        # Pit boss
  crew/           # Overseer's personal workspaces
    dave/         # Full clone, persistent
    emma/         # Full clone, persistent
    fred/         # Full clone, persistent
```

## Key Differences from Polecats

- Location: crew/ instead of polecats/
- Lifecycle: User-managed, not witness-managed
- Auto-cleanup: Never (polecats auto-cleanup on swarm land)
- Issue assignment: Optional (polecats require it)
- Tmux: Optional (polecats require it)
- Mail & Handoff: Yes for both
- Identity: Persistent (polecats are ephemeral)

## CLI Commands

- gt crew add <name> [--rig <rig>] - Create crew workspace
- gt crew list [--rig <rig>] - List crew workspaces
- gt crew at <rig>/<name> - Attach to workspace (start session)
- gt crew attach <name> - Attach (infer rig from cwd)
- gt crew refresh <name> - Handoff + restart (context cycling)
- gt crew remove <name> [--force] - Remove workspace
- gt crew status [<name>] - Show workspace status

## Design Notes

- Crew workers use full git clones (not worktrees)
- Optional beads integration via BEADS_DIR
- Mail-to-self handoff works for context cycling
- No witness monitoring or nudging
- No automatic issue assignment required

## Background

Users often maintain separate repo clones for serial agent work. This is tedious to set up manually. Crew workspaces bring these into Gas Town's infrastructure while keeping user control.


Plugin: merge-oracle (merge queue analysis)

Example plugin that analyzes changesets before Refinery processes them. Builds overlap graph, classifies disjointness (parallel-safe vs needs-sequencing), uses LLM for semantic complexity, identifies high-risk patterns. Based on merge-orchestration proposal. See docs/architecture.md.


gt mail reply/thread: Conversation support

Add mail conversation features:

- gt mail reply <id> -m 'message' - Reply to a message
- gt mail thread <id> - Show all messages in a thread

Enables back-and-forth communication between agents.


Create mol-install-go-binary molecule

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

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

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

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

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

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

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


Simplify Go daemon to Deacon-watcher

Refactor internal/daemon to only: (1) check deacon/heartbeat.json every 60s, (2) poke gt-deacon if stale, (3) restart Deacon and mail for help if very stale. Remove all lifecycle processing and agent poking.


Port Gas Town to Go

Complete rewrite of Gas Town in Go for improved performance and single-binary distribution.

## Goals
- Single installable binary (gt)
- All Python functionality ported
- Federation support built-in
- Improved performance

## Phases
1. Core infrastructure (config, workspace, git wrapper)
2. Rig & polecat management
3. Session & tmux operations
4. Mail system
5. CLI commands
6. TUI (optional)


Connection interface: Protocol for local/remote ops

Abstract interface for local vs remote (SSH) operations.

## Concept

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

## Interface

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

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

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

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

## Implementations

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

## Usage

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

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

## Design Notes

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


Phase 1.2: Daemon attachment detection

Daemon polls Deacon's pinned bead to detect naked state.

## Implementation
- Daemon knows Deacon's pinned bead ID
- Every heartbeat cycle: bd show <pinned> --json
- Parse attached_molecule field
- If null/empty: Deacon is naked

## Actions on Naked
- Spawn mol-deacon-patrol
- Attach to Deacon's pinned
- Nudge Deacon to start

## Failsafes
- Keepalive file monitoring
- Stale detection (>10min no progress)
- Force nudge on stale

Depends: gt-rana.1


Phase 1.2: Configure bd for ephemeral molecule bonding

Ensure bd mol bond --ephemeral works with Gas Town setup.

## Questions for Dave

1. Does bd automatically find .beads-ephemeral/ or need explicit path?
2. How does bd mol bond --ephemeral know which repo to use?
3. Is there a redirect mechanism for ephemeral like main beads?

## Integration

From polecat/crew working directory:
```bash
bd mol bond mol-polecat-work --ephemeral --assignee $(gt whoami)
```

Should create molecule in rig's .beads-ephemeral/, not main beads.


Refinery Engineer: Role prompting and CLAUDE.md

Create refinery/CLAUDE.md with Chief Merge Engineer role context. Include:
- Role identity and responsibilities
- Decision authority (merge order, test frequency, binary rebuilds)
- Communication patterns (Witness, Deacon)
- Session lifecycle (handoff bead protocol)
- Key commands reference


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
File: .claude/hooks.json or .gastown/hooks.json
```json
{
  "hooks": {
    "pre-shutdown": [
      {"type": "command", "cmd": "./scripts/pre-shutdown.sh"}
    ],
    "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?
}

func (r *HookRunner) Fire(event Event, ctx *HookContext) []HookResult
```

## CLI Commands
```
gt hooks list [<event>]    # List registered hooks
gt hooks fire <event>      # Manually fire for testing
gt hooks test [--all]      # Validate hook config
```

## Integration Points
- internal/session/manager.go: Fire pre/post session hooks
- internal/mail/router.go: Fire mail-received hook

## New Package
internal/hooks/
├── types.go    # Event, HookConfig, HookResult
├── runner.go   # HookRunner, Fire()
└── builtin.go  # Built-in hooks (pre-shutdown checks)

## PGT Reference
gastown-py/src/gastown/hooks/

## Acceptance Criteria
- [ ] Hook config loading from JSON
- [ ] Command hooks execute subprocess
- [ ] Pre-shutdown hook integration with session stop
- [ ] CLI for listing and testing hooks


Verify architecture.md shows correct harness and rig structure

Review architecture.md diagrams:
- Verify town-level structure shows harness correctly
- Confirm rig-level mayor/rig/ is shown (it appears to be there at line 197)
- Check mermaid diagrams match ASCII diagrams
- Update if any inconsistencies found
- Cross-reference with new harness.md docs


Error handling improvements: retry logic and recovery hints

Improve error handling across GGT codebase.

## Issues Found

### 1. Silent Failures in Refinery
manager.go ProcessMR():
- git pull errors ignored
- Continues processing even on partial failures

### 2. Missing Beads CLI
Many operations silently continue if `bd` not found:
```go
// Current
tasks, err := m.loadTasksFromBeads(epicID)
if err != nil {
    // Non-fatal - swarm can start without tasks
}

// Better
if err != nil {
    return nil, fmt.Errorf("beads required: %w", err)
}
```

### 3. No Retry Logic
Network/lock errors should retry:
```go
func withRetry(attempts int, delay time.Duration, fn func() error) error {
    for i := 0; i < attempts; i++ {
        if err := fn(); err == nil {
            return nil
        }
        time.Sleep(delay)
    }
    return fmt.Errorf("failed after %d attempts", attempts)
}
```

### 4. Recovery Hints
Error messages should include fix suggestions:
```go
// Current
return fmt.Errorf("polecat not found")

// Better
return fmt.Errorf("polecat '%s' not found. Use 'gt polecat list' to see available polecats", name)
```

## Domain Error Types
```go
type SessionError struct {
    Op      string
    Polecat string
    Err     error
}

func (e *SessionError) Error() string {
    return fmt.Sprintf("session %s for %s: %v", e.Op, e.Polecat, e.Err)
}
```

## Files to Review
- internal/refinery/manager.go
- internal/swarm/manager.go
- internal/session/manager.go
- All cmd/*.go files

## Acceptance Criteria
- [ ] No silent error swallowing
- [ ] Retry logic for transient failures
- [ ] Helpful error messages with hints
- [ ] Consistent error types per domain


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


Beads epic templates for batch work patterns

Optional: Define templates for common batch work patterns.

## Concept

A template encodes a workflow pattern that can be instantiated as beads:

```yaml
# templates/batch-basic.yaml
name: basic-batch
description: Simple batch work pattern
phases:
  - name: startup
    issues:
      - title: "Verify workers ready"
  - name: working
    # Actual work issues added separately
  - name: cleanup
    issues:
      - title: "Merge all branches"
      - title: "Clean up workers"
      - title: "Report to Mayor"
```

## Usage

```bash
gt spawn --template basic-batch --epic gt-u1j --workers 3
```

Creates beads epic with template phases + actual work from gt-u1j children.

## Decision Point

Templates are OPTIONAL. The core design (beads as state, multi-wave orchestration) works without templates. Templates are sugar for common patterns.

Consider deferring to P3 or dropping entirely if beads epics with dependencies suffice.

## Note

No "swarm IDs" involved - templates just pre-populate epic/issue structure.


bd mail send: pinned column missing from schema

gt mail send fails with: sqlite3: SQL logic error: table issues has no column named pinned

Likely a schema migration issue - bd schema has 'pinned' field but SQLite table doesn't.

## Reproduction
gt mail send gastown/Immortan -s 'test' -m 'test'

## Error
table issues has no column named pinned

## Fix
Either:
1. Add migration to add pinned column
2. Remove pinned from insert if not present
3. Regenerate DB from JSONL


Test message

Testing GGT mail system


CLI: workspace commands (init, add, list)

GGT needs workspace management commands beyond install.

## Commands (beyond gt-f9x.3 install)

### gt workspace list
List all rigs in current workspace.
```
gt workspace list [--json]
```
Essentially `gt rig list` but framed as workspace view.

### gt workspace add
Add existing rig to workspace (alternative to gt rig add).
```
gt workspace add <git-url> [--name NAME]
```

### gt onboard
Interactive first-time setup wizard.
```
gt onboard
```
- Prompts for workspace location
- Creates structure via gt install
- Offers to add first rig

## Note
May be redundant with gt-f9x.3 (install) and gt-u1j.16 (rig commands).
Consider if this is needed or should be closed as covered by those.

## PGT Reference
gastown-py/src/gastown/cli/workspace_cmd.py


Test: Alpha to Beta

Sibling communication test


gt crew at/attach: Start session in crew workspace

Implement 'gt crew at <rig>/<name>' and 'gt crew attach <name>' commands:
- Start tmux session (optional - could just print cd instructions)
- Launch claude code in the workspace
- Deliver any pending mail
- Support --no-tmux to just print directory path
- 'attach' infers rig from cwd


Default polecat names: Mad Max theme instead of AdjectiveNoun

Current default naming for new polecats uses AdjectiveNoun convention.
Since rigs already provide namespacing, we can use more thematic names.

Suggestion: Use Mad Max / Fury Road character and vehicle names as defaults.
Examples: Furiosa, Nux, Slit, Morsov, Toast, Rictus, Warboy, etc.

Could also include:
- War Rig parts: Guzzler, Tanker, Pursuit
- Citadel roles: Imperator, Blackthumb, Organic
- Wasteland terms: Chrome, Witness, Shiny

Implementation:
- Add name generator in internal/polecat/ or similar
- Use when --create flag is used without explicit name
- Cycle through pool to avoid duplicates within a rig


Merge: gt-99a

Molecule execution support for polecats and crew

Enable agents to run bonded molecules through the full lifecycle.

## The Model
1. BOND - bd mol bond <template> --assignee <identity>
   Creates concrete issues, assigns root to agent

2. DISCOVER - Agent finds assigned molecules via bd ready
   DAG structure shows unblocked steps

3. WORK - Agent works through DAG, closing steps as done
   Can delegate children to lower-tier agents (haiku)

4. SURVIVE - Agent dies → beads persist
   Any agent resumes from DAG state

5. SUPERVISE - Witness monitors for stalled molecules
   Nudges owner or reassigns if dead

## Questions to Resolve
- Seed node terminology: seed vs root vs pole vs nucleus
- Assignee inheritance: single owner vs delegation model
- Stall detection: heartbeat vs activity timeout vs session monitoring

## Implementation
- Polecat startup: check for assigned molecules
- Polecat work loop: follow molecule DAG
- Witness: monitor molecule progress, detect stalls
- Mayor: can assign molecules, handle escalations

## Depends On
- beads: bd mol bond command (bd-usro in beads repo)


Swarm learning: Beads database locality gap

## PGT Bug (GGT Design Already Correct)

Mayor created issues in `~/ai/mayor/rigs/beads/.beads/` but polecats use `~/ai/beads/.beads/`. Different databases = polecats can't see Mayor's beads.

**GGT Fix**: architecture.md already specifies:
- All agents use BEADS_DIR pointing to rig-level `.beads/`
- Lines 116-143: Beads Configuration for Multi-Agent
- Lines 573-586: Rig-Level Beads via BEADS_DIR

This is a PGT implementation gap, not a design issue. GGT spawn must set BEADS_DIR correctly.


Harness & Priming: Document architecture and update all role contexts


Immediate daemon notification on lifecycle request

When gt handoff sends a lifecycle request to the daemon (via bd mail send deacon/), the daemon only discovers it on its next heartbeat poll (every 5 min). Workers wait unnecessarily for retirement.

## Current Behavior
1. Worker runs gt handoff
2. Lifecycle mail sent to deacon/ via beads
3. Worker blocks waiting for retirement
4. Daemon heartbeat runs (up to 5 min later)
5. Daemon processes lifecycle request and kills session

## Expected Behavior
Lifecycle requests should be processed immediately, not on poll interval.

## Proposed Solutions

### Option A: SIGUSR1 Signal (simplest)
1. Add SIGUSR1 handler in daemon that calls ProcessLifecycleRequests()
2. gt handoff reads daemon.pid and sends SIGUSR1 after mail send

### Option B: Unix Socket
1. Daemon listens on ~/gt/daemon/lifecycle.sock
2. gt handoff connects and sends 'process' message

### Option C: Watchfile + fsnotify
1. gt handoff touches ~/gt/daemon/lifecycle.trigger
2. Daemon uses fsnotify to detect and process

Recommend Option A for simplicity.

## Affected Files
- internal/daemon/daemon.go - add signal handler
- internal/cmd/handoff.go - send signal after mail


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


Phase 3: Callbacks and plugins

Mail-based callback protocol and plugin surface.

## Callbacks
- Polecat → Witness: shutdown requests
- Witness → Deacon: escalations, status
- Crew → Deacon: recycle requests
- Deacon → Mayor: escalations

## Plugins
- .beads/plugins.yaml registry
- Cooldown tracking
- Plugin runner in deacon patrol

Depends: Phase 2


CLI: all command for batch polecat operations

Batch operations across multiple polecats.

## Commands

### gt all start
```
gt all start [--awake-only] [<specs>...]
```
Start sessions for multiple polecats.
- --awake-only: Only start awake polecats
- specs: Polecat names, rig/polecat patterns

### gt all stop
```
gt all stop [<specs>...] [--force]
```
Stop sessions for multiple polecats.

### gt all status
```
gt all status [<specs>...] [--json]
```
Show status of multiple polecats.

### gt all attach
```
gt all attach [<specs>...]
```
Attach to multiple sessions in tmux panes/windows.

### gt all run
```
gt all run <command> [<specs>...]
```
Run command in multiple polecat sessions.

## Spec Patterns
- `Toast`: Specific polecat (in default/current rig)
- `gastown/Toast`: Specific rig/polecat
- `gastown/*`: All polecats in rig
- `*`: All polecats everywhere

## Implementation
```go
func expandSpecs(specs []string, awakeOnly bool) ([]*polecat.Polecat, error) {
    // Expand patterns to list of polecats
}

func runForAll(polecats []*polecat.Polecat, action func(*polecat.Polecat) error) error {
    // Run action for each, collect errors
}
```

## New File
internal/cmd/all.go

## PGT Reference
gastown-py/src/gastown/cli/all_cmd.py

## Acceptance Criteria
- [ ] Pattern expansion works
- [ ] Parallel execution where safe
- [ ] Aggregate error reporting
- [ ] --awake-only filter works


gt refinery start: doesn't actually start a session

## Problem

`gt refinery start gastown` reports success but doesn't start a tmux session.

## Evidence

```
$ gt refinery start gastown
Starting refinery for gastown...
✓ Refinery started for gastown

$ tmux list-sessions | grep refinery
(nothing)

$ gt refinery status gastown
State: ○ stopped
```

## Expected

Should start a tmux session (e.g., gt-gastown-refinery) with Claude processing the merge queue.

## Related

- gt-kcee: Witness commands also need implementation
- The refinery 'start' may just be updating state.json without spawning a session


/restart: Personal slash command for in-place agent restart

Create ~/.claude/commands/restart.md that restarts current Gas Town agent in place.

## Detection
- Read tmux session name: gt-mayor, gt-witness-*, gt-refinery-*, gt-polecat-*
- Fallback: check GT_ROLE env var

## Behavior by role
- mayor: gt mayor restart (sends Ctrl-C, loop respawns)
- witness: gt witness restart
- refinery: gt refinery restart
- polecat: gt polecat restart (or witness-mediated)

## Command format
Uses backticks for inline bash to detect context, then instructs Claude to run appropriate restart.


Implement bd mol bond --ephemeral flag

Add --ephemeral flag to bd mol bond command to support ephemeral molecule bonding.

## Context
Phase 1.2 of Wisp Molecule Integration (gt-3x0z.2) discovered that this flag doesn't exist.

## Requirements

1. Add --ephemeral flag to mol bond command
2. When --ephemeral is set:
   - Mark spawned issues with wisp=true
   - Optionally write to separate .beads-ephemeral/ storage (Phase 2)

## Architecture Reference
See gastown architecture.md lines 487-491 for the full ephemeral storage design.

## Related
- gt-3x0z.2: Configure bd for ephemeral molecule bonding (closed - blocked on this)


Merge: gt-rana.3

branch: polecat/dementus
target: main
source_issue: gt-rana.3
rig: gastown


Update config location: .gastown/ → config/

Move rig configuration from hidden .gastown/ to visible config/:
- config/rig.json: Rig configuration
- config/engineer.json: Engineer settings (test command, etc.)
- config/witness.json: Witness settings (heartbeat interval, etc.)

Hidden directories are poorly discovered by AI agents.


HOP: Skill vectors on work items

Add skill embeddings to work items for capability-based matching. See ~/ai/stevey-gastown/hop/CONTEXT.md. Post-v0.1 work.


Phase 1.3: gt doctor checks for ephemeral health

Add doctor checks for ephemeral beads repo.

## Checks

1. **ephemeral-exists**: .beads-ephemeral/ directory exists for each rig
2. **ephemeral-git**: It's a valid git repo
3. **ephemeral-orphans**: Molecules started but never squashed (>24h old)
4. **ephemeral-size**: Warn if ephemeral repo is >100MB (should be cleaned)
5. **ephemeral-stale**: Molecules with no activity in last hour

## Auto-fix

--fix can:
- Create missing ephemeral repo
- Clean up old completed molecules (already squashed)
- NOT auto-squash incomplete molecules (needs AI summary)


Merge: gt-frs

branch: polecat/Slit
target: main
source_issue: gt-frs
rig: gastown


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.


Rollback support: gt mq revert for problematic merges

Implement 'gt mq revert <mr-id>' for rolling back merges.

Actions:
1. Find merge commit from closed MR
2. Create revert commit: git revert <merge-commit>
3. Push revert to target branch
4. Create 'reverted' MR tracking the revert
5. Optionally reopen source issue

Options:
- --reason REASON: required explanation
- --reopen-issue: reopen the source work item

Track revert in MR metadata for audit trail.

Reference: docs/merge-queue-design.md#open-questions


Plugin: plan-oracle (work decomposition)

Plugin that helps decompose epics/issues into sub-tasks. Analyzes scope, identifies dependencies, estimates complexity for parallelization, creates beads for sub-tasks with dependency links.


CLI: doctor diagnostics and auto-repair

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

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

Checks to Implement:
Workspace Level: Config validity, Mayor mailbox, Rig registry
Rig Level: Git state, clone health, witness/refinery presence, beads sync
Swarm Level: Stuck detection, zombie sessions, heartbeat health

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


Enhance Mayor CLAUDE.md with GGT milestone tracking

Update ~/ai/CLAUDE.md (Mayor startup context) with:

1. GGT Self-Hosting Milestone section
   - Track progress toward gt replacing town
   - Key blockers: gt-h5n (merge queue), gt-974 (daemon)
   - What "self-hosting" means (GGT working on itself)

2. Recent Architecture Decisions
   - Engineer = role, Refinery = place
   - Merge queue in Beads (not branch discovery)
   - Session restart protocol

3. Transition Plan
   - Current: use town commands (PGT)
   - Target: use gt commands (GGT)
   - Switch criteria: gt-b1g closed

Keep it concise - Mayor context should be quick to scan.


LocalConnection: Local file/exec/tmux operations

LocalConnection implementation for local machine operations.

## Implementation

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

func NewLocalConnection() *LocalConnection

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

## File Operations

Direct passthrough to os package:
```go
func (c *LocalConnection) ReadFile(path string) ([]byte, error) {
    return os.ReadFile(path)
}
// etc.
```

## Command Execution

Uses exec.Command:
```go
func (c *LocalConnection) Exec(cmd string, args ...string) ([]byte, error) {
    return exec.Command(cmd, args...).Output()
}
```

## Tmux

Delegates to Tmux wrapper:
```go
func (c *LocalConnection) TmuxNewSession(name, dir string) error {
    return c.tmux.NewSession(name, dir)
}
```

## Notes

Straightforward implementation - this is the "baseline" connection that SSHConnection will mirror remotely.


Mayor startup protocol prompting

Add startup protocol to Mayor CLAUDE.md template.

## On Session Start

1. Check for handoff:
   town inbox | grep "Session Handoff"

2. If handoff found:
   - Read it: town read <msg-id>
   - Process pending escalations (highest priority)
   - Check status of noted swarms
   - Verify rig health matches notes
   - Continue with documented next steps

3. If no handoff:
   town status     # Overall health
   town rigs       # Each rig
   bd ready        # Work items
   town inbox      # Any messages
   Build your own picture of current state.

4. After processing handoff:
   - Archive or delete the handoff message
   - You now own the current state

## Handoff Best Practices

- Be specific: 'Toast has merge conflict in auth/middleware.go' not 'Toast is stuck'
- Include context: Why decisions are pending, what you were thinking
- Prioritize next steps: What is most urgent
- Note time-sensitive items: Anything that might have changed since handoff


Deacon event/timer callbacks: reactive triggers

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

## Timer Callbacks

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

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

## Event Subscriptions

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

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

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

## Event Sources

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

## Event Types

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

## Event Processing

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

## Relation to Mail

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


Merge fix/spawn-beads-path branch to main

Branch has gt nudge command; main has notification deduplication. Both valuable.

Key insight: Only ~10 commits diverged each way in mayor/rig.
- Branch: 9509afa feat(nudge): Add gt nudge command (MISSING from main)
- Main: d2fccd5 slot-based notification deduplication (KEEP)

Merge plan:
1. git merge fix/spawn-beads-path --no-ff
2. Keep nudge.go from branch
3. Keep notification.go from main
4. Merge tmux.go (both NudgeSession AND SendKeysReplace)
5. go build && go test
6. Deploy to ~/.local/bin/gt


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.

Work on ga-p6r: Add handoff protocol to spawn priming. Ensure polecats receive handoff context when spawned. When done, submit MR (not PR) to integration branch for Refinery.


Work reconciliation module

Port reconcile.py work verification to Go.

## Purpose

Verify assigned issues are completed before landing.

## Interface

```go
type ReconcileResult struct {
    CompletedIssues  []IssueInfo
    IncompleteIssues []IssueInfo
    AllComplete      bool
    PolecatsChecked  []string
    Errors           []string
}

func ReconcileWork(rig string, polecats []string) *ReconcileResult
func GetAssignedIssues(assignee string) []IssueInfo
func UnassignIssue(issueID string, resetStatus bool) error
```

## Logic

1. Get list of polecats in swarm
2. For each polecat, query beads for assigned issues
3. Categorize as completed (closed) or incomplete (open/in_progress)
4. Return summary for landing decision

## Handling Incomplete Work

If issues incomplete:
- Abort landing (default)
- Or force landing (leaves work unfinished)
- Unassign incomplete issues for future work

## Reference

PGT: swarm/reconcile.py


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.


gt crew list: List crew workspaces

Implement 'gt crew list [--rig <rig>]' command:
- List all crew workers in rig(s)
- Show status (session running, last activity)
- Show current branch and git status summary
- Support --json output


Town root .beads has schema mismatch with bd

The .beads directory at town root (/Users/stevey/gt/.beads) has an incompatible schema:

```
Error: failed to open database: failed to initialize schema: sqlite3: SQL logic error: no such column: thread_id
```

Meanwhile, gastown/.beads (symlinked to mayor/rig/.beads) works fine.

## Impact

- gt mail inbox fails at town root
- gt handoff sends mail to broken db
- Daemon can't check its inbox

## Options

1. Delete town root .beads/beads.db and let it recreate
2. Symlink town root .beads to gastown/.beads
3. Run schema migration on existing db

## Root Cause

Likely a beads version upgrade that added thread_id column, but the town root db was created before that.


Architecture: Decentralized rig structure with per-rig agents

## Decision

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

## Town Level Structure

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

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

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

## Key Decisions

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

## Role Detection

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

## Migration from PGT

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


Doctor check: Worker health and stuck detection

Detect and report stuck workers via gt doctor.

## Checks

### WorkerHealthCheck
- List all active workers (polecats with state=working)
- Check last activity timestamp for each
- Flag as potentially stuck if no progress for configurable threshold (default: 30 min)
- Check if Witness is running for the rig
- Verify Witness last heartbeat time

### Stuck Detection Criteria
- Polecat state=working but session not running
- Polecat state=working but output unchanged for threshold
- Witness not responding to health checks
- Multiple polecats in same rig all stuck

## Output

```
[WARN] Workers in rig 'wyvern' may be stuck:
  - Toast: working for 45m, no recent output
  - Capable: working for 52m, session not found
  - Witness: last heartbeat 20m ago

  Suggestions:
  - gt witness status wyvern
  - gt capture wyvern/Toast 50
  - gt stop --rig wyvern (kill all)
```

## Auto-Fix

Cannot auto-fix stuck workers (risk of data loss), but can:
- Restart Witness daemon if crashed
- Send warning mail to Mayor


Merge: gt-g44u.1

branch: polecat/Ace

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

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

## Root Cause

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

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

## Fix Options

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

## Also Affected

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

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


Test message

Test body


Interrupt vs Queue mail semantics

Add priority/delivery semantics to mail messages.

## Semantics

| Type | Delivery | Use Case |
|------|----------|----------|
| Interrupt | tmux send-keys | Lifecycle, URGENT, stuck detection |
| Queue | Create message only | Normal mail, status, heartbeat |

## Implementation

- `bd mail send --interrupt` uses tmux send-keys notification
- Default is queue (agent checks with `gt mail check`)
- Urgent flag on messages for interrupt delivery

## Agent Side

- `gt mail check --quiet` - non-blocking check for queued mail
- `gt mail wait` - block until mail arrives (for idle agents)
- Heartbeats become queued, agent checks at natural breakpoints


Deacon Kernel: event processing molecule architecture

Extend the Deacon from "health orchestrator" to "event processing kernel" that runs a
molecule (rounds) each wake cycle, like an OS kernel scheduler.

## Core Insight

The Deacon already has:
- Wake cycle (daemon poke, timer, lifecycle request)
- Mail as event queue
- Health scanning
- Lifecycle processing

But it is REACTIVE. This epic makes it PROACTIVE with a structured molecule:

```
Deacon Wake
├── Step 0: Session Check (should I cycle myself?)
├── Step 1: Health Scan (Mayor, Witnesses, Crew, Refineries)
├── Step 2: Lifecycle Processing (cycle/restart/shutdown requests)
├── Step 3: Plugin Execution (scheduled, event-triggered, human-requested)
├── Step 4: Event Callbacks (timers, subscriptions)
└── Step 5: Heartbeat + Wait
```

## Key Design Decisions

1. **Session cycling first** - Token costs are quadratic with session length.
   Deacon should aggressively cycle to fresh sessions. First step of every
   wake is "do I need a new session?" based on context budget.

2. **Pinned bead with marching orders** - A pinned bead (like gt prime for
   agents) defines the Deacon's rounds molecule. This is the Deacon's
   "kernel" - its operating loop.

3. **Keepalive file for daemon quieting** - Instead of daemon tmux-poking
   the Deacon (which interrupts work), Deacon writes a keepalive file.
   Daemon reads it and backs off. Worst case: Deacon forgets, gets one
   extra heartbeat it squelches.

4. **Molecule-based rounds** - The wake cycle becomes a molecule with steps.
   Each step can have plugins (inline attention). Steps can be added/modified
   by updating the pinned bead.

## Architecture

```
Go Daemon (minimal, dumb)
├── Reads {townRoot}/deacon/keepalive.json
├── If fresh: do nothing
├── If stale: poke Deacon (fallback)
└── Process lifecycle requests (still daemon's job)

Deacon (Claude agent, smart)
├── Wakes: poke, timer, mail event
├── Writes keepalive (quiets daemon for duration of rounds)
├── Runs rounds molecule:
│   ├── session-check: cycle if context budget low
│   ├── health-scan: check agents, remediate
│   ├── lifecycle: process requests
│   ├── plugins: run scheduled/triggered plugins
│   ├── events: process timer/event callbacks
│   └── complete: update heartbeat, wait
└── Reads marching orders from pinned bead
```

## Relation to Existing Work

- Extends gt-5af (Deacon infrastructure) - CLOSED
- Relates to gt-axz (Plugin architecture) - P3
- Fits into phase3-deacon of gt-ngpz (Christmas Plan)
- Enables gt-976 (Crew lifecycle) as part of health-scan step


gt mq integration create: create integration branch for epic

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

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

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

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

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


Batch Work System: Integration branch, merge queue, landing

## Overview

This epic tracks batch work coordination in GGT. Key insight: **work is a stream, not discrete swarms**.

There are no "swarm IDs" - the epic IS the grouping, the merge queue IS the coordination. "Swarming an epic" is colloquial for spawning multiple workers on its children.

## Architecture

- **Epics** group related work
- **Issues** are individual tasks
- **Dependencies** encode ordering (multi-wave emerges automatically)
- **Merge queue** coordinates completed work
- **Workers** process issues independently

See Key Decision #11 in docs/architecture.md: "Work is a Stream (No Swarm IDs)"

## What This Epic Covers

1. Integration branch management for batch merges
2. Refinery semantic merge processing
3. Witness landing protocol (cleanup)
4. Report generation (epic-based, not swarm-ID-based)
5. Git safety auditing
6. Work reconciliation

## What Was Removed

- Swarm IDs (sw-1, sw-2, etc.)
- Per-swarm directories (.gastown/swarms/<id>/)
- Swarm manifest/state/events files
- swarm-started/swarm-landed beads

These were redundant - beads already provides hierarchy, status, dependencies, and history.

## References

- Architecture: docs/architecture.md (Key Decision #11, Multi-Wave Work Processing)
- PGT: swarm/manager.py, swarm/landing.py (behavioral reference, but ignore swarm ID patterns)


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

Resource Beads: Leases, locks, and quotas

Resource beads represent reserved resources. Types: vm, lock, slot, quota. Fields: holder, expires, renewable. Daemon monitors for expiry and manages contention.


Interactive prompts for destructive operations

Add interactive confirmations for destructive operations.

## Operations Needing Confirmation
- `gt swarm cancel` - Cancels active swarm
- `gt swarm land --force` - Force landing
- `gt polecat decommission` - Removes polecat
- `gt rig remove` - Removes rig
- `gt stop --all` - Stops all sessions
- `gt mail purge` - Permanently deletes mail

## Implementation Options

### Option 1: promptui library
```go
import "github.com/manifoldco/promptui"

prompt := promptui.Prompt{
    Label:     "Delete polecat Toast",
    IsConfirm: true,
}
result, err := prompt.Run()
```

### Option 2: Simple stdin
```go
func confirm(prompt string) bool {
    fmt.Printf("%s [y/N]: ", prompt)
    var response string
    fmt.Scanln(&response)
    return strings.ToLower(response) == "y"
}
```

## Bypass Flags
All confirmations skippable with --force or --yes:
```go
if !force && !confirm("Really cancel swarm?") {
    return nil
}
```

## Acceptance Criteria
- [ ] Destructive ops prompt by default
- [ ] --force or --yes bypasses
- [ ] Clear prompt text explaining action
- [ ] Non-interactive mode (piped input) auto-fails


Outpost assignment policy: Smart work routing

## Overview

Policy engine for deciding which outpost gets which work.

## Policy Configuration

```yaml
policy:
  # Default order of preference
  default_preference: [local, gce-burst, cloudrun-burst]

  # Rules applied in order
  rules:
    # Background work → Cloud Run (cheap)
    - condition: "priority >= P3"
      prefer: cloudrun-burst

    # Long tasks → VM (persistent)
    - condition: "estimated_duration > 30m"
      prefer: gce-burst

    # Specific epic → specific outpost
    - condition: "epic == gt-abc"
      prefer: local
```

## Implementation

```go
type AssignmentPolicy struct {
    DefaultPreference []string
    Rules             []PolicyRule
}

type PolicyRule struct {
    Condition string   // Simple expression
    Prefer    string   // Outpost name
    Require   string   // Must use this outpost
}

func (p *AssignmentPolicy) SelectOutpost(
    issue Issue,
    outposts map[string]Outpost,
) Outpost {
    // Check rules in order
    for _, rule := range p.Rules {
        if rule.Matches(issue) {
            if op, ok := outposts[rule.Prefer]; ok {
                if op.ActiveWorkers() < op.MaxWorkers() {
                    return op
                }
            }
        }
    }

    // Fall back to default preference
    for _, name := range p.DefaultPreference {
        if op, ok := outposts[name]; ok {
            if op.ActiveWorkers() < op.MaxWorkers() {
                return op
            }
        }
    }

    return nil  // All outposts at capacity
}
```

## Condition Language

Simple expressions, not a full DSL:

```
priority >= P3
priority == P0
estimated_duration > 30m
epic == gt-abc
type == bug
label contains "urgent"
```

## Files

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

## Problem

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

## Evidence

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

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

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

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

After nudge, polecat immediately starts working correctly.

## Hypothesis

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

## Resolution Plan

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

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

## Workaround

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


Phase 3.2: mol-polecat-work squash step

Add summary+squash as final steps in mol-polecat-work.

## Current Steps

1. read-assignment
2. understand-task
3. implement-solution
4. verify-tests
5. commit-work
6. signal-done

## Updated Steps

1. read-assignment
2. understand-task
3. implement-solution
4. verify-tests
5. commit-work
6. **generate-summary** ← NEW
7. **squash-molecule** ← NEW
8. signal-done

## Step Definitions

### generate-summary
Agent writes a concise summary following the template.
Save to a local variable or temp file.

### squash-molecule
Run: bd squash $MOLECULE_ROOT --summary "$SUMMARY"
This creates digest in main beads, cleans ephemeral.

## Update Location

This requires updating the mol-polecat-work definition in beads molecule catalog.


CLI: plugin commands (list, status)

Add gt plugins <rig> to list plugins and gt plugin status <name> to check plugin state. Simple directory scan of <rig>/plugins/.


Test: release command verification


Remove gt mail dependency on bd mail commands

Replaced bd mail send/inbox/read/ack with bd create/list/show/close. Messages are now stored as beads issues with type=message.


Machine registry: Store and manage machine configs

Registry for managing remote machines in federation.

## Data Model

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

## Interface

    }
}
```


gt mq submit: create MR from current branch

Implement 'gt mq submit' command that creates a merge-request bead.

Auto-detection logic:
1. Branch: current git branch
2. Issue: parse from branch name (polecat/Nux/gt-xyz → gt-xyz)
3. Target: main (or integration branch if --epic specified)
4. Worker: parse from branch name
5. Rig: current rig

Options:
- --branch BRANCH: explicit source branch
- --issue ISSUE: explicit source issue
- --epic EPIC: target integration/EPIC instead of main
- --priority P: override priority (default: inherit from source issue)

Creates merge-request bead and prints MR ID.

🤝 HANDOFF: Investigate beads-sync divergence (221 files)

## Context

gt doctor now detects orphaned code on beads-sync branch. Running it shows:

  beads-sync-orphans: 221 file(s) on beads-sync not in main

This is in the gastown repo (checking from crew/max).

## Background

- Earlier today we recovered orphaned mail migration code lost in merge 96c773f
- Recently simplified architecture: all workers use mayor/rig/.beads (redirects)
- This simplification may have caused beads-sync branch to diverge unexpectedly

## Investigation Steps

1. From crew/max run: git diff main..beads-sync --stat
2. Check if beads-sync should even exist anymore (was for multi-clone sync)
3. If obsolete with redirect architecture, consider deleting it
4. If it has legitimate changes, cherry-pick or merge to main

## Key Question

With all workers using mayor/rig/.beads via redirects, is beads-sync still needed?

## Commands

git log main..beads-sync --oneline | head -20
git diff main..beads-sync -- *.go | head -100


gt mq submit: creates task type instead of merge-request type

## Problem

`gt mq submit` creates an issue with `type: task` but should be `type: merge-request`.

## Evidence

```
$ bd show gt-n508
gt-n508: Merge: gt-70b3
Status: open
Priority: P1
Type: task      <-- WRONG, should be merge-request
...
Description:
type: merge-request   <-- Correct type is in description, not in actual type field
```

## Impact

`gt mq list` shows empty queue because it queries for `type: merge-request`

## Fix

`gt mq submit` should set `--type merge-request` when creating the bead.

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


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.


Timed Beads: Scheduled recurring work

## Summary

Timed beads wake up periodically and get injected into the ready queue by the daemon.

## Schema Extension

```yaml
id: gt-weekly-sync
type: task  # or sentinel
schedule: "0 9 * * 1"  # cron: Monday 9am
# OR
interval: 24h          # every 24 hours
tier: haiku            # cheap model for routine checks
next_run: 2025-12-20T09:00:00Z
```

## Daemon Integration

Daemon heartbeat loop:
1. Check timed beads where `next_run <= now`
2. For each due bead:
   - Inject into ready queue (set status to open if needed)
   - Update `next_run` based on schedule/interval
3. Witnesses pick up work via `bd ready`

## Use Cases

- Weekly team sync reminders
- Daily health checks
- Periodic cleanup tasks
- Scheduled reports

## Interaction with Pinned Beads

A pinned bead can be timed - it wakes up periodically but never closes.
This is how you model "background services" in Gas Town.

CloudRun cost tracking: Usage monitoring and limits

## Overview

Track Cloud Run usage costs and enforce spending limits.

## Cost Model

Cloud Run pricing (approximate):
- CPU: ~$0.000024/vCPU-second
- Memory: ~$0.0000025/GiB-second
- Requests: ~$0.40/million

For 5-minute worker (2 vCPU, 4GB):
- CPU: 300 × 2 × $0.000024 = $0.0144
- Memory: 300 × 4 × $0.0000025 = $0.003
- **Total: ~$0.017 per session**

## Implementation

```go
type CostTracker struct {
    cpuRate    float64  // per vCPU-second
    memRate    float64  // per GiB-second
    sessions   []SessionCost
    mu         sync.RWMutex
}

type SessionCost struct {
    WorkerID  string
    StartTime time.Time
    EndTime   time.Time
    CPUs      float64
    MemoryGiB float64
}

func (t *CostTracker) RecordSession(workerID string, start, end time.Time, cpus, mem float64) {
    t.mu.Lock()
    defer t.mu.Unlock()
    t.sessions = append(t.sessions, SessionCost{...})
}

func (t *CostTracker) CurrentCost() float64 {
    t.mu.RLock()
    defer t.mu.RUnlock()
    var total float64
    for _, s := range t.sessions {
        duration := s.EndTime.Sub(s.StartTime).Seconds()
        total += duration * s.CPUs * t.cpuRate
        total += duration * s.MemoryGiB * t.memRate
    }
    return total
}
```

## Cost Cap Enforcement

```go
func (o *CloudRunOutpost) Spawn(...) (Worker, error) {
    if o.costCap > 0 && o.costTracker.CurrentCost() >= o.costCap {
        return nil, ErrCostCapExceeded
    }
    // ... spawn worker
}
```

## Config

```yaml
outposts:
  - name: cloudrun-burst
    type: cloudrun
    cost_cap_hourly: 5.00   # Stop spawning if hourly cost exceeds $5
    cost_cap_daily: 50.00   # Daily limit
```

## CLI

```bash
gt outpost status cloudrun-burst
# Shows: Cost (today): $0.42 / $50.00 cap
```

## Files

- `internal/cloudrun/cost.go`

## Dependencies

Depends on: gt-9a2.8 (basic CloudRunOutpost)


Design: Polecat Beads write access

Design for granting polecats direct beads write access.

## Background

With Beads v0.30.0 tombstone-based rearchitecture, we have solid multi-agent support. Reversing the original read-only decision.

## Benefits

- Simplifies architecture (no mail-based issue filing proxy)
- Empowers polecats to file discovered work
- Beads handles work-disavowal

## Complications

For OSS projects where you cannot commit to project .beads/, need per-rig beads repo configuration.

## Subtasks (implementation)

- gt-zx3: Per-rig beads configuration schema
- gt-e1y: Worker prompting updates for beads access
- gt-cjb: Witness proxy removal
- gt-082: Beads sync in decommission checklist

**Design complete.** Each subtask has full specification in its description.


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.

Molecule converge: iterate until AI says done

Work isn't 'done' until AI is confident it's done. Fixes the 85% problem.

**From VC**: internal/iterative/converge.go - 3-7 iterations with AI convergence detection. ~600 lines.
Target: 20%+ more issues discovered. Observed: ~25% average improvement.

**Gas Town implementation**: Molecule converge config:
```yaml
converge:
  strategy: ai
  min_iterations: 3
  max_iterations: 7
  confidence: 0.85
```

Polecat iterates, AI checks convergence. Stop when AI is confident or max reached.

**Value**: Raw agents get to ~85% and stop. Iteration catches the remaining 15%.

**VC metrics**: Convergence rate >70%, mean 4-5 iterations for complex work.


Git safety audit module

Port git_audit.py safety checks to Go.

## Purpose

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

## Checks

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

## Beads-Only Classification

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

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

## Interface

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

func (r *GitAuditResult) HasCodeAtRisk() bool

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

CLI: worker status reporting commands

Worker status reporting CLI for polecats to report progress.

## Commands

### gt worker started
```
gt worker started <issue-id> [-m MESSAGE]
```
Reports work started on issue.

### gt worker progress
```
gt worker progress <issue-id> <0-100> [-m MESSAGE]
```
Reports percentage complete.

### gt worker blocked
```
gt worker blocked <issue-id> <reason> [-m MESSAGE]
```
Reports blocked status with reason.

### gt worker completed
```
gt worker completed <issue-id> [-m MESSAGE]
```
Reports task completion.

### gt worker failed
```
gt worker failed <issue-id> <reason> [-m MESSAGE]
```
Reports task failure.

## Implementation
Each command sends mail to refinery with structured content:
```go
type WorkerStatusReport struct {
    IssueID    string
    Status     string  // started|progress|blocked|completed|failed
    Progress   int     // 0-100 for progress
    Reason     string  // for blocked/failed
    Message    string  // optional detail
    ReportedAt time.Time
}
```

## Message Format
Subject: "[STATUS] <issue-id>: <status>"
Body: JSON-encoded WorkerStatusReport

## Default Recipient
```go
// Determine from context
func getDefaultRecipient() string {
    rig := os.Getenv("GT_RIG")
    if rig != "" {
        return rig + "/refinery"
    }
    return "refinery/"
}
```

## New File
internal/cmd/worker.go

## PGT Reference
gastown-py/src/gastown/cli/worker_cmd.py

## Acceptance Criteria
- [ ] All 5 commands implemented
- [ ] Status sent as mail to refinery
- [ ] Structured JSON body for parsing
- [ ] Works from polecat session context


Fix gt prime to give crew workers crew context

gt prime currently gives Mayor context to all agents. Crew workers should get crew-specific context. Also extract shared theory of operation from mayor priming into shared context for all roles.


Plugin: work-oracle (pre-dispatch analysis)

Plugin for pre-dispatch task analysis and decomposition.

## Purpose

Before dispatching workers for an epic, ask work-oracle to:
- Validate task breakdown
- Identify parallelization opportunities
- Predict conflicts between tasks
- Suggest worker count

## Hook Point

Mayor consults work-oracle before spawning workers.

## Interface

Input (via mail):
- Epic ID with proposed child issues
- Rig context (current state of codebase)

Output (via mail + bead):
- Recommended task groupings
- Dependency suggestions
- Risk assessment (which files might conflict)
- Optimal worker count

## Structure

```
<rig>/plugins/work-oracle/
├── CLAUDE.md       # Analysis prompts
├── mail/inbox.jsonl
└── state.json
```

Uses existing plugin-as-agent architecture.

## Note

Was "swarm-oracle" - renamed because there are no swarm IDs. This plugin helps plan batch work, not manage swarm entities.


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.


Document Overseer role (human operator)

Document the Overseer role in Gas Town architecture.

## The Overseer

The **Overseer** is the human operator of Gas Town. Not an agent - a person.

## Responsibilities

| Area | Overseer Does | Mayor/Agents Do |
|------|---------------|-----------------|
| Strategy | Define project goals | Execute toward goals |
| Priorities | Set priority order | Work in priority order |
| Escalations | Final decision on stuck work | Escalate to Overseer |
| Resources | Provision machines | Use allocated resources |
| Quality | Review & approve swarm output | Produce output |
| Operations | Run gt commands, monitor dashboards | Do the work |

## Key Interactions

### Overseer → Mayor
- Start/stop Mayor sessions
- Direct Mayor via conversation
- Review Mayor recommendations
- Approve cross-rig decisions

### Mayor → Overseer (Escalations)
- Stuck workers after retries
- Resource decisions (add machines, polecats)
- Ambiguous requirements
- Architecture decisions

## Operating Cadence

Typical Overseer workflow:
1. Morning: Check status, review overnight work
2. During day: Monitor, respond to escalations, adjust priorities
3. End of day: Review progress, plan next batch

## Commands for Overseers

```bash
gt status              # Quick health check
gt doctor              # Detailed diagnostics
gt doctor --fix        # Auto-repair issues
gt inbox               # Messages from agents
gt stop --all          # Emergency halt
```

## Documentation Updates

Add to docs/architecture.md:
- Overseer section under Agent Roles
- Clarify Mayor reports to Overseer
- Add Overseer to workflow diagrams


gt spawn: pasted work assignment needs manual Enter to start

## Problem

After `gt spawn` pastes the work assignment into Claude, the session waits for Enter.

## Current Behavior

1. `gt spawn gastown/Rictus --issue gt-xxx`
2. Session starts, work is pasted
3. Claude shows 'Pasted text #1 +53 lines' but doesn't start
4. Must manually send Enter or attach and press Enter

## Expected

The spawn should send Enter after pasting to kick off the work.

## Related

Same debounce issue as tmux notifications (gt-vnp9).


Add gt crew rename command


gt spawn: Not injecting work instructions to session

gt spawn starts session but doesn't inject the issue assignment.

Repro:
1. gt spawn gastown/Toast --issue gt-2ux
2. Session starts but polecat just sees Claude prompt
3. No issue context injected

Expected: Polecat should receive issue details automatically.
Actual: Polecat sits at blank prompt, needs manual injection.


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)


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


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.
```


Epic: Wisp Molecule Integration

## Vision

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

## The Steam Engine Metaphor

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

## Architecture

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

## Vocabulary

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

## Key Design Decisions

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

## Digest Contents

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

## Integration Points

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

## Phases

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


Polecat beads not synced with rig beads

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

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

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

## Root Cause

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

## Fix Options

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

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

```

## Add Flow

1. Create directory: `<rig>/polecats/<name>/`
2. Clone rig repo into it (or copy from rig root)
3. Create new branch: `polecat/<name>`
4. Initialize polecat state file
5. Create mail inbox

## Remove Flow

1. Verify session not running
2. Check for uncommitted changes (warn/error)
3. Remove directory
4. Clean up state

## State Persistence

Store in `<rig>/polecats/<name>/state.json`


bd pin command fails: invalid field for update: pinned

In beads v0.32.0, `bd pin <id>` fails with 'invalid field for update: pinned'. The pinned field exists in the schema but update logic doesn't handle it.

Repro:
```
bd create 'test issue'
bd pin <id>
# Error: invalid field for update: pinned
```

Expected: Issue should be pinned.

This blocks gt mail send --pinned from working.


gt spawn should create fresh polecat worktree, never reuse

Currently gt spawn tries to reuse existing polecats, which causes:

1. Stale beads database
2. Stale code (behind main/integration)
3. Old inbox messages
4. Git history pollution

## Current Behavior

gt spawn:
1. Looks for idle polecat in pool
2. If found, reuses existing worktree
3. Assigns new issue

## Desired Behavior

gt spawn:
1. Always create FRESH polecat from current main/integration
2. Fresh worktree with clean beads
3. No reuse of old worktrees

## Name Pool Still Useful

Keep name pool for:
- Allocating themed names (mad-max, etc.)
- Tracking which names are in use

But worktrees should be created fresh each time.

## Implementation

In spawn.go, before starting work:
1. If worktree exists: remove it first
2. Create fresh worktree from integration branch
3. Sync beads from rig to polecat
4. Then proceed with work assignment

This ensures polecats always start with latest code and beads.


Refinery gates: test/lint/build before merge

Before merging polecat work to main, run configurable quality gates.

**From VC**: internal/gates/ - parallel execution with timeout, any failure = overall failure.

**Gas Town implementation**: Refinery config with gate commands:
```yaml
gates:
  test:
    cmd: go test ./...
    timeout: 5m
  lint:
    cmd: golangci-lint run
    timeout: 2m
  build:
    cmd: go build ./...
    timeout: 3m
parallel: true
```

If gates fail, don't merge. Polecat can iterate and retry.

**Value**: Prevents broken code from reaching main. VC had 90.9% gate pass rate.

**VC complexity**: ~200 lines Go
**Gas Town complexity**: ~10 lines YAML


Crew directory structure and config

Add crew/ directory support to rig structure. Include:
- crew/ as peer to polecats/, refinery/, witness/
- Crew worker subdirectories with full git clones
- Optional BEADS_DIR configuration for beads integration
- Crew state tracking (separate from polecat state)

Deacon rounds molecule: the kernel execution loop

Define and implement mol-deacon-rounds - the molecule the Deacon executes each wake.

## Molecule Definition

```markdown
# mol-deacon-rounds

The Deacon kernel - executed on every wake cycle.

## Step: session-check
Check context budget. If low, cycle to fresh session.
Needs: (none - always runs first)

## Step: health-scan
Check health of all monitored agents:
- Mayor (gt-mayor session)
- Witnesses (gt-*-witness sessions)
- Refineries (gt-*-refinery sessions)
- Crew (gt-*-* sessions, lifecycle only)

Remediate unhealthy agents:
- Restart dead sessions
- Nudge stuck agents
- Escalate if remediation fails

Needs: session-check

## Step: lifecycle
Process pending lifecycle requests from mail:
- LIFECYCLE: <identity> requesting cycle
- LIFECYCLE: <identity> requesting restart
- LIFECYCLE: <identity> requesting shutdown

Needs: health-scan

## Step: plugins
Run due plugins:
1. Check scheduled plugins (cron-like)
2. Check event-triggered plugins (from mail events)
3. Check human-requested plugins (from mail)
4. Execute each, record outcomes

Needs: lifecycle

## Step: events
Process timer and event callbacks:
- TIMER: <identity> wake at <time>
- EVENT: <type> <payload>

Notify relevant agents or trigger actions.

Needs: plugins

## Step: complete
Finalize the cycle:
1. Update heartbeat.json
2. Clear/update keepalive.json
3. Log summary
4. Return to prompt (wait for next wake)

Needs: events
```

## Execution

The Deacon reads this molecule from its pinned bead and executes steps in order.
Each step:
1. Announces "Starting <step>"
2. Performs the step logic
3. Records outcome
4. Proceeds to next step

## Step Plugins

Each step can have inline plugins (additional attention):
```yaml
step: health-scan
  plugins:
    - advanced-diagnostics  # Run if basic scan finds issues
```

## Relation to bd mol

Uses the same molecule format as bd mol for polecats.
Deacon molecule is special: it's the kernel, not work.


Remove stale migration docs from gastown-py

The gastown-py repo has migration-related documentation that is now misinformation since we have made design decisions. Remove or clearly mark as obsolete: any docs about migration paths, old architecture assumptions, or superseded designs.

Test Epic: GGT MVP Validation


Deacon: Hierarchical health-check orchestrator

Replace daemon heartbeats with Deacon - an AI agent that keeps Gas Town running.

## Core Concept

The Deacon is a **Claude agent** (not just a Go process) that:
- Lives at town root in gt-deacon session
- Has its own mailbox (deacon/ identity in town beads)
- Is poked by a minimal Go daemon every ~60s (if idle)
- Monitors Mayor and Witnesses proactively
- Handles lifecycle requests (restart/cycle) from Mayor, Witnesses, AND Crew

## Architecture

```
Minimal Go Daemon (just watches Deacon)
         |
         v
     Deacon (Claude agent)
         |
    +----+----+
    v         v
  Mayor    Witnesses --> Polecats (Witness-managed)
    |         |
    +----+----+
         |
      Crew (lifecycle only, not monitored)
```

## Deacon Responsibilities

**Proactive monitoring:**
- Mayor health (tmux session, keepalive freshness)
- Witness health (tmux sessions, keepalive freshness)

**Reactive lifecycle:**
- Process restart/cycle requests from Mayor, Witnesses, Crew
- Kill session, create new, prime, verify startup

**Escalation:**
- Mail human (configurable) if issues can't be resolved

## Key Files

- ~/gt/DEACON.md - Role context
- ~/gt/deacon/ - State directory
  - heartbeat.json - Written each wake cycle (daemon checks this)
  - state.json - Health tracking, last scan results
- ~/gt/.beads/ - Town beads with deacon/ mail identity

## Wake Cycle

1. Write heartbeat (prevents daemon from poking)
2. Check mail (lifecycle requests)
3. Quick health scan (Mayor, Witnesses)
4. Process lifecycle requests
5. Remediate unhealthy agents
6. Update state

## Session Patterns

- Deacon: gt-deacon
- Mayor: gt-mayor
- Witness: gt-<rig>-witness
- Crew: gt-<rig>-<name> (e.g., gt-gastown-max)

## Relation to Policy Beads

Future: Deacon behavior configurable via policy beads (gt-3zw).
Initial implementation uses sensible defaults.

CloudRun protocol types: WorkRequest, WorkEvent, WorkResult

## Overview

HTTP protocol types for Cloud Run work dispatch. **Types only** - server and client are separate tasks.

## Request Type

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

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

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

## Response Types (streaming NDJSON)

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

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

## Files

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

## Notes

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


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


Daemon heartbeat: worker and queue monitoring

Daemon periodic checks for work progress.

## Heartbeat Actions

Every N seconds (configurable):

1. Check Witness health per rig
   - Poke if witness needs to nudge workers

2. Check Refinery queue per rig
   - Poke if pending work in queue

3. Check work completion
   - If epic children all closed, notify Mayor

## Eventually Convergent

Multiple signals reinforce state:
- Polecat signals done → Witness notices → pokes Refinery
- Daemon heartbeat → checks queue → pokes Refinery
- Beads status → queryable by any agent

Even if one signal missed, system converges.

## Interface

```go
func (d *Daemon) HeartbeatLoop() {
    for {
        for _, rig := range d.rigs {
            d.CheckWitness(rig)
            d.CheckRefinery(rig)
            d.CheckWorkProgress(rig)
        }
        time.Sleep(d.config.HeartbeatInterval)
    }
}
```

## Notifications

Use mail with low priority for heartbeat pokes.
Agents can ignore if already processing.


Clarify Mayor vs Witness cleanup responsibilities

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

## The Rule

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

## Why This Matters

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

## What Witness Handles

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

## What Mayor Handles

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

## Escalation Path

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

## Anti-Patterns

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

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

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


Automatic spawn for ready work

Auto-spawn polecats for ready work:

When Witness has capacity (active_workers < max_workers):
1. Query bd ready for unblocked issues
2. Filter to rig-appropriate work (by prefix or epic)
3. For each ready issue up to capacity:
   - gt spawn --issue <id>
   - Track that we spawned for this issue

Configuration (in rig config.json):
- max_workers: 4 (default)
- spawn_delay: 5s between spawns
- auto_spawn: true/false

This enables 'fire and forget' swarming:
- Mayor creates epic with children
- Mayor tells Witness to work epic
- Witness spawns polecats automatically
- Witness cleans up as they complete


Update prompts.md: Engineer role and templates

Update docs/prompts.md with Engineer role:

1. Role Prompts table: Change Refinery to Engineer
2. Add Engineer-specific prompts:
   - Session restart request template
   - Subtask filing template
   - Handoff mail template
3. Update refinery.md template name to engineer.md
4. Ensure consistency with architecture.md


Design: Swarm shutdown and worker cleanup

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

## Key Decisions

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

## Subtasks (implementation)

- gt-sd6: Polecat decommission checklist prompting
- gt-f8v: Witness pre-kill verification protocol
- gt-eu9: Witness session cycling and handoff
- gt-gl2: Mayor vs Witness cleanup responsibilities

**Design complete.** Each subtask has full specification in its description.


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.

Rig doctor checks: Refinery health, clones, gitignore

Rig-level doctor checks.

## Checks

### RigIsGitRepo
- Verify .git/ directory exists
- Verify git status works
- Fix: Cannot auto-fix

### GitExcludeConfigured
- Check .git/info/exclude contains Gas Town dirs
- Required entries: polecats/ witness/ refinery/ mayor/
- Fix: Append missing entries

### WitnessExists
- Verify witness/ directory exists
- Verify witness/rig/ is a git clone
- Verify witness/mail/inbox.jsonl exists
- Fix: Create structure, clone repo

### RefineryExists
- Verify refinery/ directory exists
- Verify refinery/rig/ is a git clone
- Verify refinery/mail/inbox.jsonl exists
- Fix: Create structure, clone repo

### MayorCloneExists
- Verify mayor/ directory exists
- Verify mayor/rig/ is a git clone
- Fix: Create structure, clone repo

### PolecatClonesValid
- For each polecat in polecats/:
  - Verify is a git clone
  - Verify on polecat branch
  - Warn if has uncommitted changes
- Fix: Cannot auto-fix (data loss risk)

### BeadsConfigValid (if applicable)
- If .beads/ exists, verify bd commands work
- Check beads sync status
- Warn if out of sync
- Fix: Run bd sync

## Implementation

```go
var RigChecks = []Check{
    &RigIsGitRepoCheck{},
    &GitExcludeConfiguredCheck{},
    &WitnessExistsCheck{},
    &RefineryExistsCheck{},
    &MayorCloneExistsCheck{},
    &PolecatClonesValidCheck{},
    &BeadsConfigValidCheck{},

Witness swarm landing protocol

Witness responsibilities for swarm landing cleanup.

## Trigger

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

## Landing Protocol

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

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

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

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

## Code at Risk Handling

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

## Reference

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


Update architecture.md: Engineer role and Beads merge queue

Update docs/architecture.md with recent design decisions:

1. Agent table: Change "Refinery" role to "Engineer"
   - Refinery = place/module/directory
   - Engineer = role (agent that works in the Refinery)

2. Merge Queue section: Document Beads-native model
   - MRs are beads issues with --type=merge-request
   - gt mq commands (submit, list, next, process, reorder)
   - Ordering via depends-on links

3. CLI section: Add gt mq commands

4. Key Design Decisions: Add decisions for:
   - #15: Merge Queue in Beads
   - #16: Engineer role (distinct from Refinery place)
   - #17: Session restart protocol for Engineer


bd create --dedup: semantic deduplication before issue creation

Before creating issue, check for semantic duplicates using AI similarity.

**From VC**: internal/deduplication/ - AI-powered batch comparison. ~300 lines.
VC had issue pollution problem: 438 issues with ~350+ spam because no early dedup.

**Gas Town implementation**: CLI flag on bd create:
```bash
bd create --dedup --title="Fix auth bug" --description="..."
```

Checks recent issues (7-day window) with AI similarity. If confidence >0.85, warns or blocks.

**Value**: Prevents pollution from parallel workers discovering same issues.

**VC lesson**: 115 issues filed in single day (Nov 2) because supervisor over-discovered without dedup. Rate limiting + dedup are essential.
