Patrols: Cyclic molecules for autonomous maintenance

## Vision

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

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

## Core Concepts

### 1. Cyclic Molecules

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

Patrols have a loop_to field specifying where to restart.

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

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

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

### 3. The Beacon

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

Without beacon, nothing proactive happens.

### 4. Session Reset as Patrol Step

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

### 5. Multi-Role Patrols

Each supervisor has its own patrol:

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

### 6. Cadence Tiers

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

### 7. Best-Effort Scheduling

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

## Open Questions

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

## Related

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

## Metaphor

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

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


gt mail: Cross-level routing is broken

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


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


Phase 2: Quiescent agents (Witness, Refinery)

Enable Witness and Refinery to sleep until triggered.

## Scope
- Wake triggers: gt spawn, MR submit, mail, Deacon ping
- Wake SLA: <1 minute
- mol-witness-patrol and mol-refinery-patrol definitions
- Quiescent entry/exit protocol

## Implementation
- Kill tmux session on quiescent entry
- Preserve sandbox (worktree, state files)
- Restart session on wake trigger
- Agent checks pinned, spawns default patrol if naked

Depends: Phase 1 complete


Swarm: report generation

Generate markdown reports for completed swarms.

## Command
```
gt swarm report <swarm-id> [--save <file>]
```

## Report Content

### Header
- Swarm ID and title
- Created/completed timestamps
- Duration
- Rig name

### Task Summary
| Task | Assignee | Status | Duration |

## Implementation
```go
func GenerateReport(swarmID string) (*SwarmReport, error)
func (r *SwarmReport) ToMarkdown() string
```

## Storage
- Save to <rig>/.gastown/swarms/<id>/report.md
- Or user-specified path with --save

## PGT Reference
gastown-py/src/gastown/swarm/manager.py generate_report()

## Acceptance Criteria
- [ ] Markdown report generated
- [ ] Includes all sections above
- [ ] Auto-saved to swarm directory
- [ ] --save allows custom path


Molecule Workflow Engine: Composable Crystallized Workflows

# Epic: Molecule Workflow Engine

**Vision**: Molecules are crystallized, composable, nondeterministic-idempotent workflow templates. Any worker can pick up where any other worker was interrupted and continue along the molecule.

**Christmas Target**: Full molecule-based workflow engine operational by Dec 25, 2025.

## The Core Concepts

1. **Molecule**: Read-only workflow template (beads issue with type=molecule)
2. **Atom/Step**: Individual work unit with prose instructions
3. **Bond**: Dependency between steps
4. **Polymer/Derived**: Molecule composed from other molecules
5. **Instance**: Concrete beads created when molecule is attached to work

## Key Features Needed

### 1. Molecule Composition (Includes Directive)
Molecules can include other molecules:
\`\`\`markdown
## Molecule: gastown-polecat
Includes: mol-engineer-in-box

## Step: install-binary
Build and install the local gt binary.
Needs: submit
\`\`\`

### 2. Standard Molecules
- mol-install-go-binary: Single step to build/install gt
- mol-gastown-polecat: engineer-in-box + install-binary

### 3. Spawn Integration
\`gt spawn --issue <id> --molecule <mol-id>\` creates molecule instance then starts polecat on first ready step.

### 4. Nondeterministic Idempotence
- Steps are atomic (pending → in_progress → completed)
- Any worker can pick up any ready step
- Step timeout/recovery for stuck workers

## Success Criteria
- [ ] Polecats can be spawned with mol-gastown-polecat
- [ ] Derived molecules work end-to-end
- [ ] 10+ polecat swarm completes molecule workflows
- [ ] install-go-binary step runs after successful merges

Witness daemon: heartbeat loop, spawn ephemeral agent

Background daemon for agent lifecycle and monitoring.

## Core Responsibilities

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

## Session Lifecycle (Witness Protection)

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

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

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

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

## Interface

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

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

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

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

## Heartbeat Loop

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

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


Document merge queue architecture

Update docs/architecture.md with:

- Merge Queue section explaining Beads-native approach
- Engineer role (renamed from Refinery)
- Session restart protocol
- gt mq command reference
- Federation considerations for queue

Also update any references to .gastown/ → config/.


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.


Merge: gt-h5n.5

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


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.


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.


gt spawn beads sync warning is misleading for redirect-based polecats

## Problem

When spawning a polecat, gt spawn shows a warning:
```
Warning: beads sync: exit status 1
```

This is misleading because polecats using the redirect architecture (`.beads/redirect`) share the canonical database at `mayor/rig/.beads/beads.db`. The 'stale beads' indicated by the warning is just git branch divergence (main vs beads-sync), not actual data staleness.

## Expected Behavior

gt spawn should either:
1. Skip the beads sync check for polecats using redirects (they share the canonical DB)
2. Or provide a clearer message like 'beads redirect active, using shared database'

## Reproduction

```bash
gt spawn --issue gt-xxx --rig gastown --create
# Shows 'Warning: beads sync: exit status 1' even though beads are current
```

## Root Cause

spawn.go calls beads sync and treats any non-zero exit as a warning. But with redirects, the polecat doesn't need its own beads - it uses the canonical source via the redirect chain:
```
polecat/.beads/redirect -> ../../.beads -> gastown/.beads/redirect -> mayor/rig/.beads
```

## Fix Options

1. Check for .beads/redirect before calling sync
2. Have bd sync return 0 when redirect is present
3. Suppress the warning in spawn when redirect exists


Document harness concept in docs/harness.md

Create comprehensive harness documentation:
- What is a harness (installation directory)
- Recommended structure and naming
- .beads/redirect for default project
- config/ contents (rigs.json, town.json)
- Mayor home vs rig-level mayor/
- Example configurations
- Relationship to rigs


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)


gt prime: Refinery context detection and output

Update gt prime to detect Refinery role:
- Detect from directory: refinery/rig/ = Refinery
- Show handoff bead reference
- Show merge queue status
- Show polecat branches with unmerged commits
- Show last actions summary


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.

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


Complete gt crew commands (list, attach, remove, refresh, status)

Add remaining crew subcommands to internal/cmd/crew.go:

1. gt crew list - List crew workspaces with status
2. gt crew at/attach - Start tmux session in crew workspace
3. gt crew remove - Remove crew workspace (with safety checks)
4. gt crew refresh - Context cycling with mail-to-self handoff
5. gt crew status - Show detailed workspace status

Build on existing crew add implementation in internal/cmd/crew.go.
Reference closed issues gt-cik.3-7 for original requirements.

Refinery background daemon mode

Refinery currently only works in foreground mode. Background daemon is stubbed.

## Current State
manager.go line 128-129:
```go
// Background mode: spawn a new process
// For MVP, we just mark as running - actual daemon implementation in gt-ov2
return nil
```

## Requirements

### 1. Background Process Spawning
```go
func (m *Manager) Start(foreground bool) error {
    if !foreground {
        // Spawn gt refinery start --foreground as subprocess
        cmd := exec.Command(os.Args[0], "refinery", "start", m.rig.Name, "--foreground")
        cmd.Start()  // Don't wait
        // Record PID
    }
}
```

### 2. PID File Management
- Write PID to .gastown/refinery.pid
- Check PID validity on status
- Clean up stale PID files

### 3. Log Output
- Redirect stdout/stderr to .gastown/refinery.log
- Log rotation (optional for MVP)

### 4. Graceful Shutdown
- Handle SIGTERM/SIGINT
- Complete current merge before exit
- Update state to stopped

### 5. Health Check
- Process existence check via kill -0
- Optional: heartbeat file with timestamp

## Files to Modify
- internal/refinery/manager.go: Start(), Status(), process spawning

## Acceptance Criteria
- [ ] gt refinery start <rig> spawns background process
- [ ] gt refinery status shows running with PID
- [ ] gt refinery stop sends SIGTERM and waits
- [ ] Logs written to .gastown/refinery.log
- [ ] Survives terminal close

gt rig reset --stale: Clear orphaned in_progress items

Reset in_progress issues when their assigned agent no longer exists.

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

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

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

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

Add role-specific subcommands that delegate to core commands (agent UX)

- `gt crew restart <member>`

But these don't exist - the actual commands are:
- `gt nudge <session> <message>`
- `gt polecat reset <name>`

This creates friction in agent UX. Agents shouldn't have to memorize the 'correct' command structure.

## Proposal

Add subcommands to each role that delegate to core commands with argument reordering:

```
gt witness nudge furiosa "Start working"
  → gt nudge gt-gastown-furiosa "Start working"

gt polecat nudge gastown/furiosa "Check mail"
  → gt nudge gt-gastown-furiosa "Check mail"

gt crew nudge gastown/max "Wake up"
  → gt nudge gt-crew-gastown-max "Wake up"
```

## Benefits

1. **Discoverable**: Agents explore `gt witness --help` and find nudge
2. **Lenient**: Multiple valid ways to express the same intent
3. **Role-contextual**: Commands under the role namespace feel natural
4. **Extensible**: Pattern works for future subcommands (status, reset, etc.)

## Implementation

Each role command (witness, polecat, crew, refinery) gets thin wrapper subcommands:

```go
// In witness.go
witnessCmd.AddCommand(&cobra.Command{
    Use:   "nudge <polecat> <message>",
    Short: "Nudge a polecat (delegates to gt nudge)",
    RunE: func(cmd *cobra.Command, args []string) error {
        session := formatSession(rig, args[0])
        return runNudge(session, args[1])
    },
})
```

## Future Candidates

Other subcommands to add as role-specific aliases:
- `gt polecat status <name>` (already exists, good pattern)
- `gt witness check <polecat>` → trigger a manual check
- `gt refinery merge <mr-id>` → process specific MR
- `gt crew send <member> <message>` → mail to crew member


Session management: start, stop, attach, capture

Polecat session lifecycle management.

## Interface

```go
type SessionManager struct {
    tmux *Tmux
    rig  *Rig
}

func NewSessionManager(tmux *Tmux, rig *Rig) *SessionManager

// Lifecycle
func (sm *SessionManager) Start(polecat string, opts StartOptions) error
func (sm *SessionManager) Stop(polecat string) error
func (sm *SessionManager) IsRunning(polecat string) (bool, error)
func (sm *SessionManager) List() ([]SessionInfo, error)

// Interaction
func (sm *SessionManager) Attach(polecat string) error
func (sm *SessionManager) Capture(polecat string, lines int) (string, error)
func (sm *SessionManager) Inject(polecat string, message string) error

type StartOptions struct {
    WorkDir   string   // defaults to polecat clone dir
    Issue     string   // optional: issue to work on
    Command   string   // optional: override claude command
}

type SessionInfo struct {
    Polecat   string
    SessionID string
    Running   bool
    StartedAt time.Time
}
```

## Session Naming

`gt-<rig>-<polecat>` (e.g., `gt-wyvern-Toast`)

## Start Flow

1. Verify polecat clone exists
2. Check no existing session
3. Create tmux session in polecat workdir
4. Send initial command: `claude` or custom
5. If issue provided, inject initial prompt

## Stop Flow

1. Capture final output (for logging)
2. Send exit/quit command
3. Wait briefly for graceful shutdown
4. Kill session if still running

## Capture

Uses tmux capture-pane to get recent output. Returns last N lines.

## Inject

Sends text to session via tmux send-keys. Used for:
- Mail notifications
- Witness nudges
- User messages


Swarms of One: Lightweight single-worker task dispatch

Design and implement a lightweight pattern for firing off single workers to handle tasks without full swarm overhead.

## Context

Currently we have:
- town spawn: Creates a polecat in a rig with issue assignment
- Swarms (sw-*): Full lifecycle tracking with manifest, state, events, reports
- Ephemeral rigs (rig-*): Temporary worker groups for swarms

What's missing: A simple way to say 'fire off a worker to do X' without swarm ceremony.

## Design Questions

1. Should this be a new command like 'gt fire' or an option on existing commands?
2. Should single tasks still get swarm IDs (sw-N) for consistency/queryability?
3. Should it default to creating new workers or support --reuse for idle polecats?
4. How does this relate to crew workers (gt-cik)?

## Possible Interface

gt fire --rig gastown --issue gt-xyz [--prompt '...']
gt fire gastown/QuickTask --issue gt-xyz

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.


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


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


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.

BUG: gt done doesn't push branch to origin - work lost when worktree deleted

## Problem

`gt done` creates a merge-request record in beads but **never pushes the branch to origin**.

When polecats are cleaned up (worktrees deleted), the branch is lost forever. The MR record exists but there's no actual branch to merge.

## Evidence

12 MQ items had `ready` status but no corresponding branches on origin. All polecat worktrees were deleted, losing all work.

## Impact

**CRITICAL**: All polecat work is silently lost unless polecats manually push (which they don't know to do).

## Fix

In `done.go`, before creating the MR:
1. `git push origin <branch>` to push the branch to remote
2. Only create MR record if push succeeds

## Location
`mayor/rig/internal/cmd/done.go:124-135`


🤝 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


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.


gt session capture: Support positional line count argument

Make 'gt session capture gastown/Toast 50' work.

Currently requires: gt session capture gastown/Toast -n 50
Should also accept: gt session capture gastown/Toast 50

Agent UX principle: commands should work the way agents guess they work.

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

Swarm state persistence: manifest + state + events

Upgrade swarm persistence to match PGT pattern.

## Current State
Single .gastown/swarms.json with all swarms.

## Target State (per-swarm)
```
.gastown/swarms/
└── <swarm-id>/
    ├── manifest.json  # Immutable config
    ├── state.json     # Mutable progress
    ├── events.jsonl   # Audit log
    └── report.md      # Generated report
```

## File Schemas

### manifest.json (immutable after creation)
```json
{
  "id": "sw-1",
  "title": "Epic description",
  "epic_id": "gt-abc",
  "rig": "gastown",
  "base_commit": "abc123",
  "integration_branch": "swarm/sw-1",
  "target_branch": "main",
  "workers": ["Toast", "Nux"],
  "tasks": [{"id": "gt-xyz", "title": "..."}],
  "created_at": "2024-01-01T00:00:00Z"
}
```

### state.json (mutable)
```json
{
  "state": "active",
  "task_states": {
    "gt-xyz": {"state": "merged", "assignee": "Toast"}
  },
  "updated_at": "2024-01-01T01:00:00Z",
  "error": null
}
```

### events.jsonl (append-only audit)
```jsonl
{"event": "created", "ts": "...", "data": {...}}
{"event": "task_assigned", "ts": "...", "data": {...}}
{"event": "task_merged", "ts": "...", "data": {...}}
```

## Benefits
- Audit trail via events.jsonl
- Manifest immutability prevents corruption
- Cleaner separation of concerns
- Per-swarm isolation

## Migration
Keep backward compat with swarms.json during transition.

## Files to Modify
- internal/swarm/manager.go: Refactor persistence
- internal/cmd/swarm.go: SwarmStore → directory-based

## Acceptance Criteria
- [ ] Per-swarm directory structure
- [ ] Events logged to JSONL
- [ ] Manifest immutable after creation
- [ ] List command aggregates from directories


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`.
