Deacon keepalive: quiet daemon during rounds

Replace tmux-poke interrupts with a keepalive file the daemon respects.

## Problem

Current daemon pokes Deacon via tmux SendKeys every ~5 minutes if heartbeat
is stale. This can INTERRUPT the Deacon mid-work, especially during long
plugin execution or health remediation.

## Solution

Deacon writes a keepalive file at start of rounds:
```json
{
  "timestamp": "2025-12-20T15:30:00Z",
  "expected_duration_minutes": 10,
  "action": "executing mol-deacon-rounds"
}
```

Daemon reads this and backs off:
- If keepalive is fresh AND within expected_duration: skip poke
- If keepalive is stale OR past expected_duration: poke (fallback)

## Files

- `{townRoot}/deacon/keepalive.json` - Written by Deacon
- Daemon already reads `{townRoot}/deacon/heartbeat.json` - similar pattern

## Deacon Behavior

1. Start of rounds: write keepalive with expected duration
2. End of rounds: write heartbeat (existing), clear/update keepalive
3. If rounds take longer than expected: Deacon gets one poke, squelches it

## Daemon Changes

Modify `pokeDeacon()` in daemon.go:
1. Check keepalive.json freshness and expected_duration
2. If within bounds: skip poke, log "Deacon active"
3. If past bounds: poke as fallback

## Worst Case

Deacon crashes mid-rounds without clearing keepalive:
- Daemon waits until expected_duration expires
- Then pokes, triggering respawn loop
- Max delay: expected_duration (configurable, default 10-15 min)

## Configuration

In pinned kernel bead:
```yaml
config:
  rounds_expected_duration_minutes: 10
```


Update vision.md with proto/mol/wisp terminology

Update the Steam Engine Metaphor section to use consistent phase terminology:

Current (vision.md):
- Proto molecules = fuel (templates)
- Wisps = steam (transient execution traces)
- Digests = distillate (permanent records)

New terminology:
- **Proto** = crystal/solid - frozen template
- **Mol** = liquid - reified durable instance (tracked in git)
- **Wisp** = gas - ephemeral instance (evaporates after squash)
- **Digest** = distillate - compressed summary after squash

Key clarification needed:
- Proto → bond → creates either Mol (durable) or Wisp (ephemeral)
- The choice of Mol vs Wisp depends on --wisp flag
- Default is Mol (durable, recorded in main beads)
- Wisp lives in .beads-ephemeral/, squashes away


Document the Propulsion Principle

Write canonical documentation for the Universal Gas Town Propulsion Principle.

Location: gastown/mayor/rig/docs/propulsion-principle.md

Content:
- The One Rule (hook has work → work happens)
- Why it works (stateless agents, molecule-driven)
- The sling lifecycle diagram
- Agent startup protocol
- Examples and anti-patterns

This is foundational theory-of-operation documentation.

Swarm learning: Witness needs automated context cycling

Furiosa hit 2% context during swarm work. Witness role needs automated detection of low context and should trigger session cycling before agents get stuck. Add to Witness responsibilities in prompts.md.


MR ID generation: prefix-mr-hash convention

Generate merge-request IDs following the convention: <prefix>-mr-<hash>

Example: gt-mr-abc123 for a gastown merge request.

This distinguishes MRs from regular issues while keeping them in the same namespace.
The hash should be derived from branch name + timestamp for uniqueness.

Implement: GenerateMRID(prefix, branch string) string

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

## Summary

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

## Motivation

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

## Config Types to Migrate

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

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

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

## Implementation

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

## Naming Convention

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

## Dependencies

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

gt spawn should use bd mol run for molecule attachment

Simplify Gas Town to use bd mol run for work tracking.

## Key Insight
Two distinct mechanisms, not duplicative:

| Mechanism | Purpose | Query |
|-----------|---------|-------|
| **Pinned molecule** (bd mol run) | What am I working on? | `bd list --pinned --assignee=me` |
| **Handoff mail** | Context notes for restart | `gt mail read` (self-addressed) |

The handoff is just **mail to yourself** - optional context notes.
The molecule is **the actual work** - required state.

## Current State (Overengineered)
Gas Town has custom attachment system:
- Permanent "Foo Handoff" pinned beads per identity
- AttachMolecule(pinnedBeadID, moleculeID)
- Attachment fields parsed from description
- Separate from beads pinning

## New Model (Simplified)
Use bd mol run directly:

```bash
# Spawn polecat with molecule
bd mol run mol-polecat-work --var issue=gt-xyz
# This: spawns, assigns to caller, pins root, sets in_progress
```

Query current work:
```bash
bd list --pinned --assignee=gastown/furiosa --status=in_progress
```

Handoff context (when needed):
```bash
gt mail send gastown/furiosa -s "Context notes" -m "Was on step 4..."
```

## Changes Required

### Remove from Gas Town
- AttachMolecule() / DetachMolecule()
- AttachmentFields struct and parsing
- GetAttachment() / SetAttachmentFields()
- Permanent pinned handoff beads per identity
- Daemon attachment detection (checkDeaconAttachment)

### Update gt spawn
```go
// Old: custom molecule instantiation + attachment
// New: just call bd mol run
cmd := exec.Command("bd", "mol", "run", protoID, "--var", "issue="+issueID)
```

### Update gt prime / agent context
```go
// Old: find handoff bead, parse attachment
// New: query for pinned molecule
cmd := exec.Command("bd", "list", "--pinned", "--assignee="+identity, "--status=in_progress", "--json")
```

### Update documentation
- Remove handoff bead attachment docs
- Clarify: handoff = mail, molecule = work
- Update CLAUDE.md templates

## Benefits
1. One system for work tracking (beads)
2. Simpler Gas Town code
3. bd mol squash works naturally
4. Handoff is just mail (already works)

Molecule instantiation: create child beads from template

When instantiating a molecule on a work bead:

## Transaction Flow

1. Parse molecule's `## Step:` sections from description
2. Begin SQLite transaction
3. For each step, create child issue:
   - ID: `{parent-id}.{step-ref}` or generated
   - Title: step title (from header or first line)
   - Description: step prose instructions
   - Type: task
   - Priority: inherit from parent
4. Add `instantiated-from` edge from each step to molecule:
   ```sql
   INSERT INTO dependencies (issue_id, depends_on_id, type, metadata)
   VALUES (step_id, mol_id, 'instantiated-from', '{"step": "implement"}');
   ```
5. Wire inter-step dependencies from `Needs:` lines
6. Commit transaction (atomic - all or nothing)

## Parsing Conventions

```markdown
## Step: <ref>
<prose instructions>
Needs: <step>, <step>  # optional
Tier: haiku|sonnet|opus  # optional hint
```

## Parameterization

Steps can have `{{variable}}` placeholders:
```markdown
## Step: implement
Implement {{feature_name}} in {{target_file}}.
```

Context map provided at instantiation time.

## API

```go
func (s *Store) InstantiateMolecule(mol *Issue, parent *Issue, ctx map[string]string) ([]*Issue, error)
func ParseMoleculeSteps(description string) ([]MoleculeStep, error)
```

Implementation lives in `internal/beads/molecule.go`.


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


Per-epic config overrides: custom merge settings

Allow per-epic merge configuration overrides.

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

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

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

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


tmux notifications: display-message too subtle, use send-keys instead

## Problem

`tmux display-message` notifications are not visible enough - they appear briefly in the status bar and are easy to miss.

## Current Behavior

router.go uses:
```go
r.tmux.DisplayMessageDefault(sessionID, notification)
```

## What Works

Sending echo commands directly to the terminal:
```bash
tmux send-keys -t <session> "echo '📬 NEW MAIL from mayor'" Enter
```

## Proposed Fix

Change notification method to send visible output to the terminal, perhaps with a box/banner:
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📬 NEW MAIL from mayor
Subject: <subject>
Run: bd mail inbox
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

## Considerations

- This interrupts the terminal output (acceptable for important mail)
- Could check if Claude is mid-response and queue notification
- Or use tmux popup if available

Additional issues:
1. Enter key not sent properly when chained with send-keys
2. Need to debounce and send Enter separately
3. Correct pattern: send text, sleep briefly, then send Enter

Worker cleanup: Beads sync on shutdown

Add beads sync verification to worker cleanup checklist and Witness verification.

## Update to Decommission Checklist (gt-sd6)

Add to pre-done verification:
- bd sync --status must show 'Up to date'
- git status .beads/ must show no changes

## Beads Edge Cases

Uncommitted beads changes:
  bd sync
  git add .beads/
  git commit -m 'beads: final sync'

Beads sync conflict (rare):
  git fetch origin main
  git checkout main -- .beads/
  bd sync --force
  git add .beads/
  git commit -m 'beads: resolve sync conflict'

## Update to Witness Verification (gt-f8v)

When capturing worker state:
  town capture <polecat> "bd sync --status && git status .beads/"

Check for:
- bd sync --status shows 'Up to date'
- git status .beads/ shows no changes

If beads not synced, nudge:
  WITNESS CHECK: Beads not synced. Run 'bd sync' then commit .beads/. Signal done when complete.


gt mail inbox doesn't find crew worker mail - identity mismatch

## Problem

Crew workers don't see their handoff messages when running `gt mail inbox` from their working directory.

## Root Cause

gt derives identity from cwd path, but crew workers have a different path structure:
- **cwd**: `/Users/stevey/gt/beads/crew/dave`
- **gt derives**: `beads/crew/dave` (wrong)
- **should be**: `beads/dave` (crew workers use `rig/name` format)

Messages sent to `beads/dave` don't show up because gt is looking for `beads/crew/dave`.

## Workaround

Use explicit identity flag:
```bash
gt mail inbox --identity "beads/dave"
```

## Fix

Identity detection in gt should handle crew/ subdirectory:
- Path `<rig>/crew/<name>` should derive identity as `<rig>/<name>`
- This matches how polecats work: `<rig>/polecats/<name>` → `<rig>/<name>`

## Affected

All crew workers in all rigs.

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.


gt session restart/status: Complete session management

Add missing session subcommands:

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

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


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


Adaptive backoff for daemon heartbeat

Track agent responsiveness and adjust heartbeat frequency.

## Per-Agent State

```go
type AgentBackoff struct {
    BaseInterval    time.Duration  // 60s default
    CurrentInterval time.Duration  // grows when busy
    MaxInterval     time.Duration  // 10min cap
    ConsecutiveMiss int            // pokes with no response
}
```

## Strategy Options

- **Fixed**: Always 60s (current, simple)
- **Geometric**: 60s → 90s → 135s → 202s (factor 1.5)
- **Exponential**: 60s → 120s → 240s (factor 2, aggressive)

## Recovery

When agent responds (runs a command):
- Reset ConsecutiveMiss to 0
- Return to BaseInterval immediately

## Benefits

- Reduces noise for busy agents
- Saves resources during quiet periods
- Still catches stuck agents (max interval cap)


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

Git wrapper: shell out to git

Wrapper for git operations via subprocess.

## Interface

```go
type Git struct {
    workDir string
}

func NewGit(workDir string) *Git

// Core operations
func (g *Git) Clone(url, dest string) error
func (g *Git) Checkout(ref string) error
func (g *Git) Fetch(remote string) error
func (g *Git) Pull(remote, branch string) error
func (g *Git) Push(remote, branch string, force bool) error

// Commit operations
func (g *Git) Add(paths ...string) error
func (g *Git) Commit(message string) error
func (g *Git) CommitAll(message string) error

// Query operations
func (g *Git) Status() (*GitStatus, error)
func (g *Git) CurrentBranch() (string, error)
func (g *Git) HasUncommittedChanges() (bool, error)
func (g *Git) RemoteURL(remote string) (string, error)

// Merge operations
func (g *Git) Merge(branch string) error
func (g *Git) Rebase(onto string) error
func (g *Git) AbortMerge() error
func (g *Git) AbortRebase() error
```

## Implementation

Shell out to git binary via exec.Command. Parse output where needed (Status, CurrentBranch).

## Error Handling

- Wrap git stderr in error messages
- Detect specific failures (merge conflict, auth failure, not a repo)
- Return structured errors for callers to handle

## Testing

- Use temp directories with real git repos
- Test both success and failure paths

Fetch and conflict check: git operations for MR

Implement git operations for MR processing.

Steps:
1. git fetch origin <mr.branch>
2. git checkout <mr.target> (main or integration/xxx)
3. git merge --no-commit --no-ff <mr.branch> (test merge)
4. Check for conflicts
5. If conflicts: abort and return Failure(conflict, files)
6. If clean: abort (actual merge in next step)

Helper functions:
- FetchBranch(branch string) error
- CheckConflicts(source, target string) ([]string, error)

CLI: mail commands (send, inbox, read)

CLI: mail commands wrapping bd mail.

## Status

Current implementation works with JSONL files. Refactor to wrap bd mail CLI.

## Commands

### gt mail inbox
```
gt mail inbox [--unread] [--json]
```
Wraps: `bd mail inbox [--json]`

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

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

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

## Address Translation

Same as gt-u1j.6:
- `mayor/` → `mayor`
- `<rig>/refinery` → `<rig>-refinery`
- `<rig>/<polecat>` → `<rig>-<polecat>`

## Dependencies

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.

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

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.

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)


Architecture: beads config and direct landing docs

Added to architecture.md:
- Beads multi-agent configuration table (daemon, worktree, sync-branch)
- ASCII directory layout for non-mermaid rendering
- Direct landing workflow (bypass merge queue)
- Design decisions 9 and 10 for direct landing and daemon awareness
- CLI commands for gt land


CLI: names commands for polecat naming pool

Polecat naming pool for auto-generated names.

## Commands

### gt names generate
```
gt names generate [--count N]
```
Generate N names from pool.

### gt names add
```
gt names add <name>...
```
Add custom names to pool.

### gt names list
```
gt names list
```
Show available and used names.

### gt names reset
```
gt names reset [--keep-used]
```
Reset pool to defaults.

## Config File
<rig>/town/naming.json:
```json
{
  "enabled": true,
  "auto_refill": true,
  "refill_threshold": 5,
  "pool": {
    "available": ["Toast", "Nux", "Capable", ...],
    "used": ["Alice", "Bob"]
  }
}
```

## Default Pool
Mad Max themed: Toast, Nux, Capable, Furiosa, Immortan, etc.

## Integration
gt polecat add calls naming pool if no name given:
```go
if name == "" {
    name, err = naming.Generate(rigPath)
}
```

## New Package
internal/naming/
├── pool.go     # Pool management
└── defaults.go # Default name lists

## Acceptance Criteria
- [ ] Auto-generate names on polecat add
- [ ] Track used vs available
- [ ] Auto-refill when low
- [ ] Custom names addable


mol-deacon-patrol

Deacon patrol molecule template. Label: template


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.


Activity feed from wisp state: gt patrol status

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

## Problem

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

## Desired Commands

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

## Data Sources

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

## Use Cases

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

gt spawn --continue for resuming parked molecules

Add `--continue` flag to gt spawn for resuming parked molecules:

```bash
gt spawn --continue gt-mol-root
```

This:
1. Finds molecule root
2. Verifies molecule is in "parked" state (in_progress, no assignee)
3. Checks external deps are now satisfied
4. Spawns polecat with molecule context
5. Polecat reads handoff mail and continues from blocked step

Part of cross-project dependency system.
See: docs/cross-project-deps.md

Depends on: gt-zniu (gt park)
Depends on Beads: bd-zmmy (bd ready resolution)


Merge: gt-h5n.5

branch: polecat/Scabrous
target: main
source_issue: gt-h5n.5
rig: gastown


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.


Outpost/Worker interfaces: Core abstractions for remote compute

## Overview

Define the core interfaces that all outpost types implement.

## Interfaces

```go
type OutpostType string
const (
    OutpostLocal    OutpostType = "local"
    OutpostSSH      OutpostType = "ssh"
    OutpostCloudRun OutpostType = "cloudrun"
)

type Outpost interface {
    Name() string
    Type() OutpostType
    MaxWorkers() int
    ActiveWorkers() int
    Spawn(issue string, config WorkerConfig) (Worker, error)
    Workers() []Worker
    Ping() error
    SendMail(worker string, msg Message) error  // optional
}

type Worker interface {
    ID() string
    Outpost() string
    Status() WorkerStatus  // idle, working, done, failed
    Issue() string
    Attach() error         // for interactive outposts
    Logs() (io.Reader, error)
    Stop() error
}

type WorkerConfig struct {
    RigPath    string
    BeadsDir   string
    GitBranch  string
    Context    map[string]string  // hints for worker
}
```

## Files

- `internal/outpost/outpost.go` - Outpost interface
- `internal/outpost/worker.go` - Worker interface
- `internal/outpost/config.go` - WorkerConfig, OutpostType

## Notes

This is the foundation for all federation work. Keep interfaces minimal - we can extend later.


Polecat name pooling: Bounded reusable names

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

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

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

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

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


Direct landing integration: gt land uses MR or bypasses

Integrate direct landing with merge queue.

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

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

This ensures direct landing still creates proper records.

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


Work assignment mail not received by polecat

When gt spawn sends a work assignment:

1. gt spawn says '✓ Work assignment sent'
2. Polecat runs 'gt mail inbox'
3. Shows '0 messages, 0 unread'

The work assignment mail never arrived at the polecat's inbox.

## Observed in session
- Spawned polecat dementus on gt-th7
- Polecat checked inbox: empty
- Polecat couldn't find issue (separate sync bug)

## Possible causes
- Mail routing issue for polecat addresses
- gt spawn not actually sending mail
- Mail sent to wrong address format

This was likely caused by stale beads in old polecats. With gt-9nf (fresh polecats), polecats now use shared rig beads via redirect file, eliminating sync issues. Mail routing uses town beads correctly.


CLI: gt refinery commands (start, stop, status, queue)

CLI commands for managing the Refinery agent.

## Commands

```bash
gt refinery start <rig>      # Start refinery for a rig
gt refinery stop <rig>       # Stop refinery
gt refinery status <rig>     # Show refinery status
gt refinery queue <rig>      # Show merge queue
```

## gt refinery start

Starts the Refinery daemon for the specified rig.

Options:
- --foreground: Run in foreground (default: background)
- --auto-merge: Enable auto-merge (default: from config)

## gt refinery stop

Stops a running Refinery. Gracefully finishes current MR if processing.

## gt refinery status

Shows:
- Running state (running/stopped)
- Current MR being processed (if any)
- Queue length
- Last merge time
- Recent activity

## gt refinery queue

Shows the merge queue:
```
Merge queue for 'wyvern':
  1. [pending] Toast/polecat-auth-fix (15m ago)
  2. [pending] Capable/polecat-new-feature (5m ago)

1 merged today, 0 rejected
```

## Implementation

Uses gt-ov2 (Refinery agent) for daemon functionality.


Create Refinery role template

Add Refinery template to internal/templates/roles/:
- refinery.md.tmpl with full role context
- Variables: rig name, working directory, handoff bead ID
- Update SeedRoleTemplates to include it
- gt prime uses this template for Refinery context


CLI: witness commands (start, stop, status)

Witness daemon CLI commands.

## Commands

### gt witness start
Start the witness daemon for a rig.
```
gt witness start <rig> [--interval <seconds>]
```
- Starts background daemon process
- Default heartbeat interval: 30s
- Logs to <rig>/witness/witness.log

### gt witness stop
Stop the witness daemon.
```
gt witness stop <rig>
```
- Graceful shutdown
- Completes current heartbeat cycle

### gt witness status
Show witness status.
```
gt witness status <rig> [--json]
```
Output:
- Running/stopped
- Last heartbeat time
- Polecats being monitored
- Recent nudges/escalations

### gt witness logs
View witness logs.
```
gt witness logs <rig> [--follow] [--lines <n>]
```
- --follow: Continuous output (like tail -f)
- --lines: Number of lines (default 50)

## Daemon Management

Witness runs as background process:
- PID stored in <rig>/witness/witness.pid
- Uses nohup for persistence
- Logs structured JSON events

## Implementation

```go
var witnessCmd = &cobra.Command{Use: "witness"}
witnessCmd.AddCommand(startCmd, stopCmd, statusCmd, logsCmd)
```

Start launches daemon via exec, status reads PID file and pings process.


Outpost integration tests: Mock and E2E testing

## Overview

Integration tests for the outpost system.

## Mock Outpost

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

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

## Unit Tests

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

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

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

## Integration Tests (with mocked Cloud Run)

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

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

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

## E2E Tests (requires real Cloud Run)

```go
// +build e2e

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

## Files

- `internal/outpost/mock_test.go`
- `internal/outpost/manager_test.go`
- `internal/outpost/cloudrun_test.go`
- `internal/cloudrun/integration_test.go`

## Dependencies

Depends on: gt-9a2.8 (CloudRunOutpost), gt-9a2.15 (error handling)
Lower priority - can be done after implementations work.


HTTP work client: CloudRun dispatch client

## Overview

HTTP client for dispatching work to Cloud Run and streaming results back.

## Implementation

```go
type WorkClient struct {
    serviceURL string
    httpClient *http.Client  // HTTP/2 enabled
}

func NewWorkClient(serviceURL string) *WorkClient {
    return &WorkClient{
        serviceURL: serviceURL,
        httpClient: &http.Client{
            Transport: &http2.Transport{},
            Timeout:   0,  // No timeout for streaming
        },
    }
}

func (c *WorkClient) DispatchWork(ctx context.Context, req WorkRequest) (<-chan WorkEvent, error) {
    // 1. POST to /work
    // 2. Return channel that streams WorkEvents
    // 3. Close channel when done/error
}
```

## Streaming Reader

```go
func (c *WorkClient) streamEvents(body io.Reader, events chan<- WorkEvent) {
    defer close(events)
    decoder := json.NewDecoder(body)
    for {
        var event WorkEvent
        if err := decoder.Decode(&event); err != nil {
            return
        }
        events <- event
    }
}
```

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.

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


init.go: Replace custom contains() with strings.Contains


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.


Merge: gt-3x1.3

branch: polecat/Doof
target: main
source_issue: gt-3x1.3
rig: gastown


Molecule CLI: bd molecule commands

Add molecule commands to bd:

## Commands

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

## gt spawn integration

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

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

## Output Examples

```
$ bd molecule show mol-abc

mol-abc: Engineer in a Box
Type: molecule

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

Instances: 3
```

```
$ bd molecule instances mol-abc

Parent          Status    Created
gt-xyz          done      2025-12-15
gt-abc          active    2025-12-17 (3/5 complete)
gt-def          pending   2025-12-18
```


Refinery agent: merge queue processing loop

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

## Interface

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

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

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

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

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

## Processing Loop

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

## Merge Strategy

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

## Test Integration

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

## Notifications

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

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

## Dependencies

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


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.

Phase 1.4: Basic patrol runner in Deacon

Deacon CLAUDE.md and prime context for patrol execution.

## Deacon Context
- Update Deacon CLAUDE.md with patrol instructions
- On wake: check pinned bead for attachment
- If attached: resume molecule from current step
- Execute steps, close each when done
- On final step: burn molecule, go naked

## gt prime Enhancement
- Detect if agent has attached molecule
- Show molecule progress in prime output
- Include patrol-specific instructions

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)


TODO: Check if issue is child of configured epic in Witness

witness/manager.go:688 has a TODO to filter issues by whether they're children of the configured epic. Currently this filter is skipped.


Test: New Router

Testing bd create for mail


Create .runtime/ for town-level runtime state

Move ephemeral town state to .runtime/:
- Create ~/gt/.runtime/ directory structure
- Move daemon/state.json → .runtime/daemon.json
- Move deacon/heartbeat.json → .runtime/deacon.json
- Move .gastown/agent-state.json → .runtime/agent-requests.json
- Move .gastown/keepalive.json → .runtime/keepalive.json
- Update .gitignore to ignore .runtime/
- Update all code references


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.


🤝 HANDOFF: Timing fixes applied

Fixed mayor attach timing bug. Completed: timing fix, gt-tulx, Emma beads-6v2. Remaining P1: gt-17zr, gt-kcee, gt-szsq. Run gt prime on startup.


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

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

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

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

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

This should be standard Gas Town rig configuration.


Ephemeral rig support for ad-hoc batch work

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

## Use Case

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

## Interface

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

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

## Directory Structure

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

## Cleanup Trigger

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

## Note

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

## Reference

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


Slim down rig root config.json to identity only

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


request-shutdown

Send shutdown request to Witness.
Wait for termination.

The polecat is now ready to be cleaned up.
Do not exit directly - wait for Witness to kill the session.

Depends: generate-summary


gt spawn: Enter key needs debounce delay after paste

## Problem

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

## Observed Behavior

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

## Expected Behavior

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

## Root Cause

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

## Impact

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

## References

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


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


mol-deacon-patrol

Deacon patrol molecule template. Label: template


Implement gt sling command

The unified work dispatch command.

```bash
gt sling <thing> <target> [options]
```

Implements spawn + assign + pin in one operation. See sling-design.md.

Acceptance:
- [ ] Parse thing (proto name, issue ID, epic ID)
- [ ] Parse target (agent address)
- [ ] Spawn molecule if proto
- [ ] Assign to target agent
- [ ] Pin to agent's hook (pinned bead)
- [ ] Support --wisp flag for ephemeral
- [ ] Support --molecule flag for issue+workflow
- [ ] Error if hook already occupied (unless --force)


Deacon plugin scheduler: cron-like execution

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

## Concept

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

## Plugin Registration

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

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

## Schedule Format

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

## Execution

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

## Plugin Execution Modes

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

## State Tracking

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

## Relation to gt-axz

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


Deacon 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.


Review and audit all GGT beads

Thorough review of all filed beads in gastown GGT repo. Check for: consistency, completeness, correct dependencies, accurate descriptions, proper prioritization. Ensure beads are self-contained and dont rely on external docs.


LocalOutpost: Refactor current polecat spawning

## Overview

Refactor current local polecat spawning to implement the Outpost interface.

## Current State

Polecat spawning is ad-hoc. This task wraps it in LocalOutpost.

## Implementation

```go
type LocalOutpost struct {
    name       string
    maxWorkers int
    tmux       *Tmux
    workers    map[string]*LocalWorker
}

func NewLocalOutpost(config OutpostConfig) *LocalOutpost

func (o *LocalOutpost) Type() OutpostType { return OutpostLocal }

func (o *LocalOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    // Create tmux session
    // Start claude in pane
    // Return LocalWorker
}
```

## LocalWorker

```go
type LocalWorker struct {
    id      string
    session string  // tmux session name
    issue   string
    status  WorkerStatus
}

func (w *LocalWorker) Attach() error {
    // tmux attach-session
}
```

## Notes

- This should be a refactor, not new functionality
- Existing polecat code becomes LocalOutpost internals
- Tests should pass before and after

Depends on: gt-9a2.1 (interfaces)


Witness MVP: Automated Polecat Lifecycle

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

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

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

## Core Loop

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

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

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

  sleep 60
```

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


Polecats should auto-cleanup after MR submission

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

## Desired Flow

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

## Implementation Options

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

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

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

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


gt install command: Create workspace structure

Create Gas Town workspace structure.

## Command

```
gt install [path]
```

If path omitted, uses current directory.

## Created Structure

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

## Implementation

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

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

## Steps

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

## Error Cases

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

## Templates

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


Add Gas Town theory of operation to all role primings

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


Witness pre-kill verification protocol

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

## Protocol for Witness Prompting

```markdown
## Pre-Kill Verification Protocol

Before killing any worker session, verify workspace is clean.

### Verification Steps

When a worker signals done:

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

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

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

### Nudge Templates

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

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

### Kill Sequence

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

### Escalation

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

## Implementation

Add to WITNESS_CLAUDE.md template.


Work request: gt-976 crew lifecycle support

Hey Max, filed gt-976 for you - adding crew lifecycle support to Deacon.

Currently crew is 'human-managed' and can't request automated refresh. Would be useful for molecules that need fresh sessions mid-workflow.

Key changes:
- getManager(RoleCrew) → return deacon/ instead of human
- Teach Deacon crew session patterns
- Test with gt nudge

Priority 2, no rush but would unblock molecule automation for crew.

- Dave (beads/crew/dave)

Overhaul gt mol to match bd mol chemistry interface

## The Sling: Unified Work Dispatch

This issue tracks the overhaul of `gt molecule` to align with chemistry metaphor and introduce the **Universal Gas Town Propulsion Principle**.

### The Propulsion Principle

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

This is the one rule that drives all Gas Town agents.

### The Sling Operation

`gt sling <thing> <target> [options]` - unified command for spawn + assign + pin.

See: `gastown/mayor/rig/docs/sling-design.md`

### Implementation Tasks

| Issue | Title | Priority |
|-------|-------|----------|
| gt-4ev4 | Implement gt sling command | P1 |
| gt-uym5 | Implement gt mol status command | P1 |
| gt-i4kq | Update templates for Propulsion Principle | P1 |
| gt-7hor | Document the Propulsion Principle | P2 |

### Command Changes

| Old | New |
|-----|-----|
| `gt molecule instantiate` | `gt sling` |
| `gt molecule attach` | `gt sling --force` |
| `gt molecule detach` | `gt mol burn` |
| `gt molecule progress` | `gt mol status` |
| `gt molecule list` | `gt mol catalog` |
| `gt spawn --molecule` | `gt sling` |

### Acceptance Criteria

- [ ] `gt sling` works for protos, issues, and epics
- [ ] `gt mol status` shows hook state
- [ ] Templates updated for propulsion principle
- [ ] Old commands deprecated with warnings
- [ ] Documentation complete


Polecats should not bd sync on startup

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

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

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

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

Harness Design & Documentation

The harness (Gas Town installation directory) needs design cleanup, documentation, and tooling.

## Current Problems

1. **Shared harness confusion**: ~/ai is shared by PGT and GGT with overlapping structures
   - PGT uses ~/ai/mayor/ as town-level Mayor home
   - GGT Mayor works in ~/ai/mayor/rigs/gastown/
   - ~/ai/gastown/ has both .gastown/ (PGT) and mayor/ (git clone)

2. **Beads redirect**: ~/ai/.beads/redirect → mayor/rigs/gastown/.beads
   - This is specific to GGT's decentralized structure
   - Should be documented as an example

3. **architecture.md**: Verify rig-level mayor/rig/ is shown correctly

4. **No harness creation tooling**: Users must manually set up

## Proposed Work

- Document what a harness IS (installation directory)
- Create harness creation command or template repo
- Update architecture.md if needed
- Create example harness configuration for docs
- Resolve PGT/GGT sharing issue


Add molecule to update local go binary on push to main

When pushing to main branch, automatically rebuild and install the gt binary on the local machine so changes are immediately available.


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

Deacon tmux status bar: heartbeat timing and patrol state

## Problem

The deacon shows patrol output but lacks real-time observability:
- No indication of when last heartbeat occurred
- No indication of when next heartbeat is scheduled
- No visibility into current patrol step

## Desired Behavior

The tmux status bar for gt-deacon should show:

```
⛪ Deacon | ❤ 2m ago | ⏰ 3m | 📍 health-scan (3/7)
```

Components:
- **Role icon**: ⛪ (deacon identity)
- **Last heartbeat**: ❤ 2m ago (time since last heartbeat file update)
- **Next heartbeat**: ⏰ 3m (time until daemon would poke)
- **Current step**: 📍 health-scan (3/7) (current patrol atom, step N of M)

## Implementation

1. **Read heartbeat.json** for last update time
2. **Calculate next poke** based on daemon interval (default 5m)
3. **Read current wisp** from .beads-wisp/ to get patrol progress
4. **Update tmux status** periodically or on state change

Options:
- tmux status-right with shell script
- gt deacon status --tmux for formatted output
- Hook into patrol step completion

Design: Collapse mail into beads

## Proposal

Replace the separate mail system (JSONL inboxes) with beads issues using a naming convention.

## Rationale

If all state should be in beads (work items, swarm state, dependencies), why have a separate system for messages? Mail is just:
- Handoffs (agent → self)
- Commands (Mayor → Refinery)
- Escalations (Witness → Mayor)

These can all be beads issues with a special prefix.

## Design

### Convention
- Messages use `@-` prefix: `@-witness-1734012345`
- Assignee = recipient
- Status: open = unread, closed = read/acknowledged
- Priority 0 = urgent

### Commands (thin wrappers)
```bash
gt mail send witness -s "Subject" -m "Body"
  → bd create --prefix=@ --title="Subject" --assignee=witness --description="Body"

gt mail inbox
  → bd list --prefix=@ --assignee=$(gt whoami) --status=open

gt mail read @-abc
  → bd show @-abc && bd close @-abc
```

### Notification
Daemon watches for new `@-` issues and pokes relevant sessions.
Or: agents poll on heartbeat (simpler).

## What We Remove
- `mail/inbox.jsonl` files
- Mail JSONL read/write code
- Separate delivery mechanism

## What We Keep
- `gt mail` CLI (as wrapper)
- Handoff semantics
- Notification (via daemon or polling)

## Benefits
- One system, one sync, one query interface
- All communication in git history
- Simpler architecture

## Risks
- Beads prefix filtering must be efficient
- Namespace collision with user prefixes
- Performance for high-frequency messages (probably fine for handoffs)

## Decision Point
Do we need first-class mail support in beads (`bd mail` commands) or is convention sufficient?

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 error handling: Retry logic and resilience

## Overview

Error handling and retry logic for outpost operations.

## Error Types

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

## Retry Policy

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

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

## Retry Implementation

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

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

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

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

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

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

## Outpost Health Tracking

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

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

## Config

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

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

## Files

- `internal/outpost/retry.go`
- `internal/outpost/health.go`

## Dependencies

Depends on: gt-9a2.3 (OutpostManager)
Can be done after basic outpost implementations work.

Work on gt-fix-bugs: Fix blocking infrastructure bugs. See issue for details. Run 'bd show gt-fix-bugs' to see the full issue.


Merge: gt-h5n.5

branch: polecat/Scabrous
target: main
source_issue: gt-h5n.5
rig: gastown


Phase 1.1: Attachment field on pinned beads

Add attached_molecule field to pinned bead schema.

## Schema Change
Add to handoff/pinned bead issues:
- attached_molecule: string (root issue ID of attached mol)
- attached_at: timestamp

## Implementation
- Update beads Issue struct if needed
- Or: use labels/metadata field
- Ensure bd show displays attachment info

## Acceptance
- Can set/clear attachment on a bead
- bd show displays attachment status


Rig management: discover, load, create rigs

Rig discovery, loading, and creation.

## Interface

```go
type Rig struct {
    Name      string
    Path      string
    GitURL    string
    Config    RigConfig
    Polecats  []string
    HasWitness bool
    HasRefinery bool
}

type RigManager struct {
    townRoot string
    config   *Config
    git      *Git
}

func NewRigManager(townRoot string, config *Config, git *Git) *RigManager

// Discovery
func (rm *RigManager) DiscoverRigs() ([]*Rig, error)
func (rm *RigManager) GetRig(name string) (*Rig, error)
func (rm *RigManager) RigExists(name string) bool

// Creation
func (rm *RigManager) AddRig(name, gitURL string) (*Rig, error)
func (rm *RigManager) RemoveRig(name string) error

// Rig state
func (rm *RigManager) LoadRigConfig(rig *Rig) error
func (rm *RigManager) SaveRigConfig(rig *Rig) error
```

## Discovery Logic

1. Read rigs.json from config/
2. For each registered rig, verify directory exists
3. Load rig-level config if present
4. Scan for polecats/ subdirectory
5. Check for witness/, refinery/ directories

## Rig Creation

1. Clone repo to town root
2. Add entry to rigs.json
3. Create agent directories (polecats/, witness/, refinery/, mayor/)
4. Update .git/info/exclude to ignore agent dirs
5. Initialize rig config

## Rig Structure

Per docs/architecture.md:
```
<rig>/
├── polecats/
├── refinery/rig/
├── witness/rig/
└── mayor/rig/
```


Pinned bead naming convention for all roles

Establish consistent naming convention for pinned beads across all roles.

## Problem

Every role needs a pinned bead for molecule attachment, handoff state, and identity.
We need a consistent naming convention so gt tools can find the pinned bead for any role.

## Proposed Convention

  {role}.pinned                    - Singleton roles (deacon, mayor)
  {rig}-{role}.pinned              - Per-rig roles (witness, refinery)
  {rig}-{name}.pinned              - Named agents (polecats, crew)

Examples:
- deacon.pinned
- mayor.pinned
- gastown-witness.pinned
- gastown-refinery.pinned
- gastown-furiosa.pinned (polecat)
- gastown-max.pinned (crew)

## Storage Location

| Role | Pinned Bead Location |
|------|---------------------|
| Mayor | ~/gt/.beads/ (town level) |
| Deacon | ~/gt/.beads/ (town level) |
| Witness | {rig}/.beads/ (rig level) |
| Refinery | {rig}/.beads/ (rig level) |
| Polecat | {rig}/polecats/{name}/.beads/ |
| Crew | {rig}/crew/{name}/.beads/ |

## Why This Matters

1. Name recycling: Polecats reuse names so their pinned beads persist
2. Molecule attachment: gt mol bond needs to find the pinned bead
3. gt prime: Can show you are working on X from pinned bead
4. Crash recovery: Resume from pinned beads attached molecule

## Tasks

- Document naming convention in architecture.md
- Update gt prime to find pinned bead by convention
- Update gt mol bond to use conventional name
- Create pinned beads on role startup if missing
- Add gt pinned command to show/manage pinned beads

Refinery background daemon mode

The refinery 'gt refinery start' command only works in foreground mode (--foreground). Need to implement background daemon mode for production use.

Options:
1. Use a separate tmux session for the refinery
2. Implement proper daemonization
3. Use Claude Code session for the refinery agent

For MVP, option 1 (tmux session) is probably simplest.

TIDY UP: Your previous work (gt-odvf: bd mol CLI docs) was already merged to main. Check your git status is clean, sync beads, and if nothing to do, just run 'gt done'.


Shutdown request handler

Handle polecat shutdown requests:

When polecat runs 'gt handoff --shutdown':
1. Polecat sends mail to <rig>/witness requesting shutdown
2. Witness receives mail
3. Witness verifies:
   - Git working tree is clean
   - Work is submitted (MR exists or in queue)
   - No uncommitted beads changes
4. If clean:
   - gt session stop <rig>/<polecat>
   - git worktree remove polecats/<name>
   - git branch -d polecat/<name>
5. If not clean:
   - Send nudge back to polecat
   - Track retry count

Depends on fixing gt-dsfi (handoff deadlock).


Crew workers: design documentation and remaining work

## Summary

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

## Current Implementation

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

### Crew vs Polecat

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

## Known Bugs

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

## Potential Enhancements

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


Daemon: proper rig discovery

Currently discovers rigs by scanning tmux session names for gt-*-witness pattern. Should instead:
- Read rigs from mayor/rigs.json
- Or scan town directory for .gastown subdirs
- Handle rigs that exist but don't have running witnesses


MVP Cutover: GGT replaces PGT for batch work

When this is closed, stop using town and start using gt.

## Acceptance Criteria

1. gt spawn assigns issue to polecat and starts session
2. gt spawn --epic spawns workers for all epic children
3. gt session manages tmux lifecycle
4. gt send / gt inbox work for mail
5. Refinery processes merge queue with semantic merges
6. Integration branches created and landed correctly
7. gt stop --all halts all sessions
8. One successful test batch completed end-to-end

## What Must Work

- Spawn polecat with issue assignment
- Spawn workers for epic children
- Session start/stop/attach
- Mail send/inbox/read
- Refinery merge loop (semantic)
- Integration branch → main landing
- Witness cleanup protocol
- Emergency stop

## What Can Be Deferred

- Doctor checks (use PGT)
- TUI dashboard
- Plugin system
- Federation
- Ephemeral rigs
- Detailed landing reports

## Test Plan

1. Create epic with 2 tasks, spawn 2 workers
2. Verify polecats get assigned and sessions start
3. Simulate task completion
4. Verify Refinery merges to integration
5. Verify landing to main
6. Verify cleanup

## Validation

Run one real batch implementing GGT issues using GGT.

## Note

No "swarm IDs" - just spawn workers for epic, let merge queue coordinate.


gt done: Missing command referenced in polecat docs


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 crew session pattern to lifecycle handling

Update identityToSession and restartSession to handle crew patterns: gastown/max -> gt-gastown-max. Crew workers can request lifecycle but are not proactively monitored.


Swarm beads naming convention and auto-filing

Beads naming convention for swarm lifecycle events.

## Bead IDs

- swarm-started:<swarm-id>     # Filed when swarm begins
- swarm-task-merged:<swarm-id>:<task-id>  # Filed per task merge
- swarm-landed:<swarm-id>      # Filed when merged to main
- swarm-failed:<swarm-id>      # Filed on unrecoverable failure

## swarm-started Bead

Filed by: Mayor/Refinery at swarm creation
Contains:
- Swarm title and description
- List of tasks (issue IDs)
- List of workers (polecat names)
- Base commit SHA

## swarm-task-merged Bead

Filed by: Refinery after each successful merge
Contains:
- Task issue ID and title
- Polecat name
- Merge commit SHA
- Test results summary

## swarm-landed Bead

Filed by: Refinery after landing to main
Contains:
- Final merge commit SHA
- Stats: tasks completed, time taken
- List of all merged task beads
- Integration branch name (now deleted)

## swarm-failed Bead

Filed by: Refinery on unrecoverable failure
Contains:
- Failure reason
- Tasks merged vs not merged
- Recovery guidance

## Why Beads (not just mail)

- Persistent, queryable, synced to git
- Other agents can check status without mail
- Creates audit trail
- Works when agents offline


Mayor session cycling prompting

Add session cycling section to Mayor CLAUDE.md template.

## When to Cycle

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

## Composing Handoff Notes

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

2. Compose note with this structure:

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

## Active Swarms
<per-rig swarm status>

## Rig Status
<table of rig health>

## Pending Escalations
<issues needing your decision>

## In-Flight Decisions
<decisions being made>

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

## Delegated Work
<work sent to refineries>

## User Requests
<pending user asks>

## Next Steps
<what next session should do>

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

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

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


Update docs to reflect molecule-first paradigm

Gas Town is fundamentally a molecule execution engine. Documentation should reflect this more clearly.

## Issues Found

### 1. gt spawn examples show molecule as optional
README.md line 116: `gt spawn --issue <id> # Start polecat on issue`
Should emphasize: polecats execute molecules, not just issues.

### 2. Architecture.md spawn examples inconsistent
Line 344 shows molecule: `gt spawn --issue gt-xyz --molecule mol-engineer-in-box`
Line 1434 shows without: `gt spawn --issue <id>`

### 3. Config vs molecule distinction not clear
outposts.yaml shows static policy - should note when molecules apply.

### 4. Operational molecules section is good but buried
Lines 430-566 cover operational molecules well. Should be more prominent.

## Updates Needed
- [ ] README: Update spawn examples to show molecule usage
- [ ] architecture.md: Ensure all spawn examples include molecules
- [ ] architecture.md: Add section on "when config vs molecule"
- [ ] architecture.md: Move operational molecules higher in document
- [ ] Add principle: "If it requires cognition, it's a molecule"
- [ ] federation-design.md: Note that policy can escalate to mol-outpost-assign

## Key Message
Gas Town doesn't spawn workers on issues. It spawns workers on molecules.
The issue is just the seed data for the molecule execution.


detectSender() doesn't recognize crew workers

## Problem

`detectSender()` in mail.go only detects polecats, not crew workers.

## Current Code (line 445)

```go
// If in a rig's polecats directory, extract address
if strings.Contains(cwd, "/polecats/") {
    // extract rig/polecat
}

// Default to mayor
return "mayor/"
```

## Symptom

Emma (crew worker at `/Users/stevey/gt/beads/crew/emma`) runs:
- `gt mail inbox` → checks `mayor/` inbox (wrong!)
- Should check `beads/emma` or `beads/crew/emma`

## Fix

Add crew detection:
```go
// If in a rig's crew directory, extract address
if strings.Contains(cwd, "/crew/") {
    parts := strings.Split(cwd, "/crew/")
    if len(parts) >= 2 {
        rigPath := parts[0]
        crewName := strings.Split(parts[1], "/")[0]
        rigName := filepath.Base(rigPath)
        return fmt.Sprintf("%s/%s", rigName, crewName)
    }
}
```

## Also Check

- `gt prime` correctly detects role, so there may be another detection function that works
- Should unify detection logic


Add gt deacon start/stop/status commands

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


Policy beads: config in data plane

Use sentinel/policy beads for configuration instead of external config. Examples: daemon notifications on/off, heartbeat intervals. Config lives in the bead graph, can be toggled by closing/opening policy beads.


MCP beads tools fail from polecat directories

The beads MCP plugin (plugin:beads:beads) fails to find issues when invoked from polecat directories.

## Observed
- Polecat in /gt/gastown/polecats/dementus
- MCP tool: plugin:beads:beads - show (issue_id: 'gt-th7')
- Error: 'bd command failed: Error: no issue found matching gt-th7'

## Expected
MCP tools should work the same as running bd directly.

## Note
This may be related to gt-tmm (beads sync issue) rather than an MCP-specific bug. The MCP tool uses bd under the hood, and bd can't find the issue because the polecat's beads database is stale.


MR state transitions: validate open→in_progress→closed

Enforce valid state transitions for merge-requests:

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

Invalid:
- closed → anything (immutable once closed)

Implement validation in MR update operations.

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


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


gt crew refresh: Context cycling with handoff

Implement 'gt crew refresh <name>' command:
- Send handoff mail to self (context summary)
- Kill current session cleanly
- Start new session
- New session reads handoff mail and resumes
- Support --message to add custom handoff notes
