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)


gt rig info: Show detailed rig information

Add 'gt rig info <rig>' command to show detailed rig status.

Should show:
- Rig path and git URL
- Active polecats with status
- Refinery status
- Witness status
- Recent activity
- Beads summary (open issues count)


gt handoff: Deadlock in waitForRetirement


implement

Implement the solution for gt-test123. Follow codebase conventions.
File discovered work as new issues with bd create.

Make regular commits with clear messages.
Keep changes focused on the assigned issue.

Depends: load-context


CLI: gt stop --all (emergency swarm kill)

Emergency kill command for swarm operations.

## Commands

```bash
gt stop --all              # Kill ALL sessions across all rigs
gt stop --rig <name>       # Kill all sessions in one rig
gt stop --rig <name> --graceful  # Try graceful first, then force
```

## Implementation

### --all flag
1. List all tmux sessions matching gt-*
2. For each: capture final output, kill session
3. Update all polecat states to idle
4. Log all killed sessions
5. Send mail to Mayor: "Emergency stop executed"

### --rig flag
1. List sessions for specific rig
2. Same as above but scoped

### --graceful flag
1. First, try to inject "exit" command
2. Wait 5 seconds
3. If still running, force kill

## Output

```
Stopping all Gas Town sessions...
  [wyvern] Toast: captured output, killed
  [wyvern] Capable: captured output, killed
  [beads] Nux: captured output, killed

3 sessions stopped.
All polecat states set to 'idle'.
Mail sent to mayor/.
```

## Safety

- Always capture output before killing
- Update state files to reflect reality
- Log all operations to gt.log
- Warn if uncommitted changes detected (but still kill)

## Dependencies

Needs: Tmux wrapper, Session management, Polecat management


gt crew remove: Remove crew workspace

Implement 'gt crew remove <name> [--force]' command:
- Check for uncommitted changes, unpushed commits
- Warn and require --force if dirty
- Kill any running session
- Remove directory
- Unregister from mail


Test Task 2: Add comment to version.go


inbox-check

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


Patrol System: Agent lifecycle loops with attachments

Enable Gas Town agents to run continuous patrols, survive crashes, and hand off work across sessions.

## Core Concepts
- **Attachments**: Molecules bound to agent's pinned bead until complete
- **Patrols**: Cyclic molecules that loop (deacon, witness, refinery)
- **Quiescent**: Agents that sleep until triggered (witness, refinery)

## Design Doc
See docs/patrol-system-design.md

## Phases
Phase 1: Foundation (attachment field, daemon detection, mol-deacon-patrol)
Phase 2: Quiescent Agents (wake triggers, witness/refinery patrols)
Phase 3: Callbacks and Plugins (mail protocol, plugin runner)
Phase 4: Polish (gt patrol status, metrics, tuning)

## Key Decisions
- Attachment as field on pinned bead (not edge type, for now)
- Mail-based orchestration for all callbacks
- Queue replacement for heartbeat delivery (not pile-up)
- Burn and respawn for patrol loops (not in-place reset)


Recover stale polecat work: 4 branches with unpushed commits

During observation of polecat workflow, found 4 polecats with unpushed work:

## Branches Pushed (preserved)
- polecat/capable: 3 commits (molecule catalog, doctor orphan detection, gt done)
- polecat/dementus: 4 commits (Witness MVP, handoff fixes)
- polecat/furiosa: 2 commits (bulk polecat removal, spawn handoff)
- polecat/rictus: 1 commit (molecule docs)

## Action Required
1. Review each branch for merge-worthiness
2. Either:
   a. Create PRs for valuable work
   b. OR discard if superseded
3. After decision, clean up polecats properly

## Root Cause
Polecats were not cleaned up after previous work sessions. This is exactly why we need:
- gt-u1k: gt shutdown should fully cleanup polecats
- gt-8v8: Refuse to lose uncommitted work
- gt-9nf: Always create fresh polecats


GGT Command Parity: Complete gt command coverage

Complete gt command set to match/exceed PGT town commands.

Covers: uninstall, rig info, refinery attach, witness, session mgmt, mail UX, daemon.


gt polecat add: should handle existing branch gracefully

## Problem

`gt polecat add gastown Nux` fails if the branch `polecat/Nux` already exists.

## Current Behavior

```
fatal: a branch named 'polecat/Nux' already exists
```

## Expected Behavior

Should either:
1. Reuse the existing branch
2. Or prompt to delete/recreate
3. Or auto-suffix: polecat/Nux-2

## Context

Branch may exist from previous polecat that was removed but branch wasn't cleaned up.


gt orphans: Find lost polecat work

Add a command to find orphaned commits that were never merged to main.

## Problem
Polecat work can get lost when:
- Session killed before merge
- Refinery fails to process
- Network issues during push

## Solution
Add `gt orphans` command that:
1. Uses `git fsck --unreachable` to find dangling commits
2. Filters to recent commits (default: 7 days, configurable)
3. Excludes stash/index entries (WIP on, index on)
4. Shows commit details and suggests recovery

## Usage
```
gt orphans              # Last 7 days
gt orphans --days=14    # Last 2 weeks
gt orphans --recover    # Interactive cherry-pick
```

## Found orphans (Dec 16-20, 2025)
- 3b146c11: Fix mail read auto-ack and add Mayor startup directive
- b6fdc561: Add persistent theme config and fix crew session theming
- 97aba756: Unify gt prime to call bd prime and mail check
- ce769ca5: Add mol-bootstrap molecule for Gas Town installation
- b2219de7: Add bootstrap documentation for new Gas Town installations
- bc82348: feat: Add gt done command (already recovered)


Merge: gt-3x1

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


gt mail send should tmux-notify recipient

## Problem

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

## Expected Behavior

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

## Current Behavior

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

## Impact

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

## Implementation Notes

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

## Reference

Check PGT implementation for how it handles this.


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.


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.

Swarm learning: Refinery merge queue automation

Manually merging 15 polecat branches was painful and error-prone. Refinery should automate: detect completed work, run tests, merge to main, handle conflicts. This is core Refinery value prop.

VC Pattern Integration: Bring validated ideas to Gas Town

Analysis of ~/src/vc identified 6 validated patterns from the 2nd orchestrator attempt that map cleanly to Gas Town primitives. VC achieved 254 issues closed, 90.9% gate pass rate, and 24 successful missions.

Key insight: VC built ~4300 lines of Go for features that become ~65 lines of YAML + CLI flags in Gas Town's architecture.

Child tasks track each pattern to integrate.

gt doctor: detect orphaned code on beads-sync branch

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

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

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

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

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


gt spawn should auto-start refinery/witness if not running

When spawning a polecat, the infrastructure (refinery, witness) should already be running.

## Current Behavior
spawn.go only:1. Assigns issue to polecat2. Sends work mail3. Starts polecat session

The refinery and witness must be started separately.

## Expected Behavior (per user feedback)
When spawning a polecat, if the rig's refinery or witness is not running, auto-start them.

## Options

### Option A: spawn auto-starts infrastructure
Check if refinery/witness running before spawn, start if not.

### Option B: gt swarm start <rig> command
Explicit command that:
1. Starts refinery
2. Starts witness
3. Optionally spawns polecats on bd ready issues

### Option C: gt rig start <rig>
Similar to Option B but as rig lifecycle command.

Molecules: Composable Workflow Beads

## Summary

Molecules are crystallized workflow patterns stored as Beads issues.
When instantiated, the molecule creates child beads forming a DAG.

## Key Insight: Molecules ARE Beads

Per HOP Decision 001: Beads IS the ledger. Molecules don't get a separate YAML format - they're issues with `type: molecule` containing prose-based step definitions.

Agents don't need rigid schemas. They parse natural language natively. A molecule is just instructions with enough structure for tooling.

## Example: Engineer in a Box

```markdown
id: mol-xyz
type: molecule
title: Engineer in a Box

This workflow takes a task from design to merge.

## Step: design
Think carefully about architecture. Consider existing patterns,
trade-offs, testability.

## Step: implement
Write clean code. Follow codebase conventions.
Needs: design

## Step: review
Review for bugs, edge cases, style issues.
Needs: implement

## Step: test
Write and run tests. Cover happy path and edge cases.
Needs: implement

## Step: submit
Submit for merge via refinery.
Needs: review, test
```

## Instantiation

```bash
# Attach molecule when spawning
gt spawn --issue gt-abc --molecule mol-xyz

# Creates child beads atomically:
gt-abc.design     ← ready first
gt-abc.implement  ← blocked by design
gt-abc.review     ← blocked by implement
gt-abc.test       ← blocked by implement
gt-abc.submit     ← blocked by review, test
```

Each step issue gets an `instantiated-from` edge to the molecule (with step metadata).

## Why This Matters

1. **Unified data plane**: Everything in Beads, no parallel YAML channel
2. **AI-native**: Prose instructions, not rigid schemas
3. **Error isolation**: Each step is a checkpoint - failure doesn't lose progress
4. **Scales with AI**: As agents get smarter, they handle more complex molecules

## Implementation Primitives

- `ParseMoleculeSteps()`: Extract steps from prose (convention-based)
- `InstantiateMolecule()`: Atomic transaction creating all steps + edges
- `instantiated-from` edge type: Track provenance
- Parameterization: `{{variable}}` substitution from context map


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.

Mail orchestrator daemon

Background mail orchestrator daemon.

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

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

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

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

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

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

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

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


Test issue for spawn molecule


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
```


Auto-target: MRs for epic children target integration branch

Automatically target integration branches for epic children.

When 'gt mq submit' is called:
1. Parse source issue from branch
2. Check if issue has a parent epic
3. Check if integration/<epic> branch exists
4. If yes: set target=integration/<epic>
5. If no: set target=main

This ensures batch work automatically flows to integration branches.

Also update 'gt mq submit --epic' to explicitly target an epic's integration branch.

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


gt done: Command doesn't exist but documented in polecat CLAUDE.md

The polecat CLAUDE.md documents 'gt done' as the command to signal work is ready for merge queue, but running it gives 'unknown command'. Either implement the command or update the documentation.


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.


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

## Problem

Agents naturally guess command patterns like:
- `gt witness nudge <polecat>`
- `gt polecat nudge <name>`
- `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

Create docs explaining what a harness is (private repo containing GT installation with rigs gitignored), why you'd want one, and how to set it up with beads redirects


Phase 3.2: mol-polecat-work squash step

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

## Current Steps

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

## Updated Steps

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

## Step Definitions

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

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

## Update Location

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


gt swarm: Not discovering tasks from epic dependents

gt swarm create/start shows '0 tasks loaded' even when epic has dependents.

Repro:
1. Create epic gt-hw6
2. Create tasks and add deps: bd dep add gt-xxx gt-hw6
3. gt swarm create gastown --epic gt-hw6 --worker Toast
4. Swarm shows 'Tasks: 0'

Expected: Swarm should discover tasks that depend on the epic.
Actual: Shows '(no tasks loaded)'


Bug: LIFECYCLE messages use literal <rig> placeholder

Found stale LIFECYCLE messages addressed to @<rig>/witness instead of actual rig names like @gastown/witness. Template substitution not happening.

Examples found:
- gm-bay: LIFECYCLE: polecat requesting shutdown (to @<rig>/witness)
- gm-7du, gm-94e, gm-u5x, gm-89b: same issue

Fix: Ensure rig name is substituted in lifecycle mail templates.


Plugin: work-oracle (pre-dispatch analysis)

Plugin for pre-dispatch task analysis and decomposition.

## Purpose

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

## Hook Point

Mayor consults work-oracle before spawning workers.

## Interface

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

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

## Structure

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

Uses existing plugin-as-agent architecture.

## Note

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


gt witness: Witness management commands

Add 'gt witness' command group for witness lifecycle management.

Subcommands:
- gt witness start [rig] - Start witness for a rig
- gt witness stop [rig] - Stop witness
- gt witness status [rig] - Show witness status
- gt witness attach [rig] - Attach to witness session

Witness monitors polecats and handles:
- Idle detection and cleanup
- Session health checks
- Nudging stuck agents


Fix TestHasPolecat test failure


Merge queue: per-rig queue management

Per-rig merge queue for coordinating polecat work.

## Concept

When polecats complete work, they submit to the merge queue. The Refinery processes the queue, merging work to main in order.

## Data Model

```go
type MergeRequest struct {
    ID        string    `json:"id"`
    Polecat   string    `json:"polecat"`
    Branch    string    `json:"branch"`
    Issue     string    `json:"issue,omitempty"`
    Status    MRStatus  `json:"status"`
    CreatedAt time.Time `json:"created_at"`
    UpdatedAt time.Time `json:"updated_at"`
}

type MRStatus string
const (
    MRPending   MRStatus = "pending"
    MRReviewing MRStatus = "reviewing"
    MRMerged    MRStatus = "merged"
    MRRejected  MRStatus = "rejected"
)
```

## Interface

```go
type MergeQueue struct {
    rig  *Rig
    path string  // <rig>/refinery/queue.jsonl
}

func NewMergeQueue(rig *Rig) *MergeQueue

// Queue operations
func (mq *MergeQueue) Submit(polecat, branch string, issue string) (*MergeRequest, error)
func (mq *MergeQueue) List() ([]*MergeRequest, error)
func (mq *MergeQueue) Next() (*MergeRequest, error)  // oldest pending
func (mq *MergeQueue) Get(id string) (*MergeRequest, error)

// Status updates
func (mq *MergeQueue) SetStatus(id string, status MRStatus) error
func (mq *MergeQueue) MarkMerged(id string) error
func (mq *MergeQueue) MarkRejected(id, reason string) error
```

## Queue Storage

JSONL file at `<rig>/refinery/queue.jsonl`. FIFO ordering.

## Git Coordination

Refinery processes queue:
1. Fetch polecat branch
2. Attempt merge to main
3. Run tests (if configured)
4. Push to origin
5. Update queue status

## Conflict Handling

If merge fails:
- Mark MR as rejected
- Notify polecat to rebase


Mayor startup protocol prompting

Add startup protocol to Mayor CLAUDE.md template.

## On Session Start

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

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

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

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

## Handoff Best Practices

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


Implement gt mol status command

Show what's on an agent's hook.

```bash
gt mol status [target]
```

Output:
- What's slung (molecule name, associated issue)
- Current phase and progress
- Whether it's a wisp
- Next action hint

If no target, shows current agent's status.

Acceptance:
- [ ] Read pinned bead attachment
- [ ] Display molecule/issue info
- [ ] Show phase progress
- [ ] Indicate wisp vs durable


gt mq integration status: show integration branch status

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

Display:
- Integration branch name and creation date
- Commits ahead of main
- MRs merged to integration (closed)
- MRs pending (open, targeting integration)
- Comparison: main..integration/<epic>

Output example:
  Integration: integration/gt-auth-epic
  Created: 2025-12-17
  Ahead of main: 5 commits

  Merged MRs (3):
    gt-mr-001  Fix login timeout
    gt-mr-002  Fix session expiry
    gt-mr-003  Update auth config

  Pending MRs (1):
    gt-mr-004  Update auth tests (in_progress)

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


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)

Config package: Config, State types and JSON serialization

Config and state types with JSON serialization.

## Town Config (config/town.json)

```go
type TownConfig struct {
    Type      string    `json:"type"`       // "town"
    Version   int       `json:"version"`    // schema version
    Name      string    `json:"name"`       // town identifier
    CreatedAt time.Time `json:"created_at"`
}
```

## Rigs Registry (config/rigs.json)

```go
type RigsConfig struct {
    Version int                `json:"version"`
    Rigs    map[string]RigEntry `json:"rigs"`
}

type RigEntry struct {
    GitURL   string    `json:"git_url"`
    AddedAt  time.Time `json:"added_at"`
    BeadsConfig *BeadsConfig `json:"beads,omitempty"`
}

type BeadsConfig struct {
    Repo   string `json:"repo"`   // "local" | path | git-url
    Prefix string `json:"prefix"` // issue prefix
}
```

## Agent State (*/state.json)

```go
type AgentState struct {
    Role       string    `json:"role"`       // "mayor", "witness", etc.
    LastActive time.Time `json:"last_active"`
    Session    string    `json:"session,omitempty"`
    Extra      map[string]any `json:"extra,omitempty"`
}
```

## Interface

```go
func LoadTownConfig(path string) (*TownConfig, error)
func SaveTownConfig(path string, config *TownConfig) error

func LoadRigsConfig(path string) (*RigsConfig, error)
func SaveRigsConfig(path string, config *RigsConfig) error

func LoadAgentState(path string) (*AgentState, error)
func SaveAgentState(path string, state *AgentState) error
```

## Validation

- Version compatibility checks
- Required field validation
- Path existence verification


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


gt spawn: pasted work assignment needs manual Enter to start

## Problem

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

## Current Behavior

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

## Expected

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

## Related

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


Work on ga-lue: Implement Witness as Claude agent. Conver...

Work on ga-lue: Implement Witness as Claude agent. Convert from shell script to Claude agent that monitors polecats, nudges idle ones, handles escalations. When done, submit MR (not PR) to integration branch for Refinery.


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.


Merge execution: merge, test, push

Implement the actual merge execution.

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

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

Handle push failures with retry logic.

mol-code-review: Self-improving code review molecule

Create a code review molecule that enables Gas Town to self-improve through automated PR review. Flywheel: review generates quality checks, discovered issues, pattern learning.


Daemon: configurable heartbeat interval

Heartbeat interval is hardcoded to 60s. Should be configurable via:
- town.json config
- Command line flag
- Environment variable

Default 60s is reasonable but some deployments may want faster/slower.


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

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)


Automatic spawn for ready work

Auto-spawn polecats for ready work:

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

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

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


Merge: gt-g44u.1

Merge: gt-xw7b

branch: polecat/morsov
target: main
source_issue: gt-xw7b
rig: gastown


Fix blocking bugs (gt-dsfi, gt-n7z7, gm-c6b)

Fix bugs blocking Witness functionality:

1. gt-dsfi: handoff deadlock
   - Polecats hang when trying to exit
   - Blocks shutdown request handler

2. gt-n7z7: refinery foreground race condition
   - Sometimes detects parent as already running
   - Blocks reliable Refinery startup

3. gm-c6b: mail coordination
   - Cross-rig mail should use town-level database
   - Affects Witness <-> Mayor communication

These should be fixed early as they'll block integration testing.

Fixed gt-dsfi and gt-n7z7. Issue gm-c6b not found in database.


CloudRun persistent connections: HTTP/2 keepalive

## Overview

Implement persistent HTTP/2 connections to keep Cloud Run containers warm.

## Problem

Cloud Run has cold start latency when scaling from 0. Persistent connections keep containers warm.

## Implementation

```go
type PersistentConnectionManager struct {
    serviceURL string
    conn       net.Conn
    client     *http2.ClientConn
    mu         sync.Mutex
    lastUsed   time.Time
    keepAlive  time.Duration
}

func (m *PersistentConnectionManager) GetConnection() (*http2.ClientConn, error) {
    m.mu.Lock()
    defer m.mu.Unlock()

    // Reuse existing connection if healthy
    if m.client != nil && m.client.CanTakeNewRequest() {
        m.lastUsed = time.Now()
        return m.client, nil
    }

    // Create new connection
    return m.dial()
}

func (m *PersistentConnectionManager) keepAliveLoop() {
    ticker := time.NewTicker(m.keepAlive / 2)
    for range ticker.C {
        m.mu.Lock()
        if time.Since(m.lastUsed) > m.keepAlive {
            // Connection idle too long, close it
            m.close()
        } else {
            // Send ping to keep alive
            m.ping()
        }
        m.mu.Unlock()
    }
}
```

## Integration with CloudRunOutpost

```go
type CloudRunOutpost struct {
    // ...existing fields...
    connMgr *PersistentConnectionManager
}

func (o *CloudRunOutpost) Spawn(...) {
    conn, err := o.connMgr.GetConnection()
    // Use connection for work dispatch
}
```

## Config

```yaml
outposts:
  - name: cloudrun-burst
    type: cloudrun
    # ...
    keep_alive: 5m  # Keep connection warm for 5 minutes
```

## Files

- `internal/cloudrun/connection.go`

## Dependencies

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


Recreate beads rigs with fresh clones

## Problem

Beads rigs have schema mismatches (missing thread_id column, etc.) from development iteration.

## Tasks

1. Shut down any active polecats
2. Delete existing beads rigs: mayor/rig, refinery/rig, witness/rig, crew/*
3. Re-clone from beads repo
4. Run bd init in each new clone

## Rigs to recreate

- /Users/stevey/gt/beads/mayor/rig
- /Users/stevey/gt/beads/refinery/rig
- /Users/stevey/gt/beads/crew/* (if any)

## Source

Clone from beads repo (need to confirm remote URL)


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
```


Phase 1.3: mol-deacon-patrol definition

Define the Deacon patrol molecule in builtin_molecules.go.

## Steps
1. inbox-check - Handle callbacks from agents
2. health-scan - Ping Witnesses and Refineries
3. plugin-run - Execute registered plugins
4. orphan-check - Find abandoned work
5. session-gc - Clean dead sessions
6. context-check - Check own context limit
7. loop-or-exit - Burn and let daemon respawn, or exit if context high

## Implementation
- Add DeaconPatrolMolecule() to builtin_molecules.go
- Add to BuiltinMolecules() list
- Test with bd mol show mol-deacon-patrol


Test

Body


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.


CLI: cleanup commands for stale state

Cleanup commands for recovering from stale state.

## Commands

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

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

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

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

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

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

## New File
internal/cmd/cleanup.go

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


Add gt decommission command for clean swarm/worker shutdown

Single command to cleanly shut down a swarm and its workers: cancel swarm, stop sessions, optionally remove polecats. E.g. gt decommission gt-hw6 --cleanup

Molecule Phase Terminology Documentation

Document the three-phase molecule lifecycle with consistent terminology:

## The Phases (States of Matter)

| Phase | State | Nature |
|-------|-------|--------|
| **Proto** | Solid/Crystal | Frozen template, static definition in catalog |
| **Mol** | Liquid | Reified instance, malleable, tracked in git (durable) |
| **Wisp** | Gas | Evaporates after squash, ephemeral orchestration |

## Documentation Gaps Identified

### High Priority
1. Update vision.md Steam Engine metaphor to use proto/mol/wisp terminology
2. Add lifecycle diagram: Proto → bond → Mol or Wisp → squash → Digest
3. Document Go types for phases (ProtoMolecule, etc.)
4. Document .beads-ephemeral/ structure and purpose

### Medium Priority
5. Update CLAUDE.md files (polecat, witness, refinery) with molecule workflow
6. Document bd mol bond/squash/burn CLI API with examples
7. Add polecat guide: Executing molecules and generating summaries

### Low Priority
8. Add terminology glossary to architecture.md
9. Create troubleshooting playbook for stuck molecules
10. Add reference diagrams for state transitions

## Current State
- architecture.md has good molecule basics but uses inconsistent terminology
- vision.md has Steam Engine metaphor (proto=fuel, wisp=steam, digest=distillate)
- molecules.md has detailed reference but needs phase clarity
- builtin_molecules.go has 8 molecules but no phase documentation in code

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


Fix gt prime to give crew workers crew context

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


gt mq status: detailed MR view

Implement 'gt mq status <id>' command for detailed MR view.

Display:
- All MR fields (branch, target, source_issue, worker, rig)
- Current status with timestamps
- Dependencies (what it's waiting on)
- Blockers (what's waiting on it)
- Processing history (attempts, failures)

Under the hood: bd show <id> with MR-specific formatting.

Reference: docs/merge-queue-design.md#command-details


Witness patrol: cleanup idle orphan polecats

Add patrol step to find and cleanup polecats that are idle with no assigned issue. These orphans occur when polecats crash before sending DONE or Witness misses the message. Patrol should verify git is clean before removing worktree. Part of gt-rana.


gt crew restart command

Add a 'gt crew restart' command that kills the tmux session and restarts fresh. Useful when a crew member gets confused or needs a clean slate.

Should:
- Kill existing tmux session if running
- Start fresh session with claude
- Run gt prime to reinitialize context

Alias: gt crew rs


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?

Update config location: .gastown/ → config/

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

Hidden directories are poorly discovered by AI agents.


Witness Plugin System

Plugin infrastructure for witness patrol customization.

## Plugin Location
`<rig>/plugins/witness/<plugin-name>/`

## Plugin Structure
```
plugin.yaml   # Config: name, description, trigger, tier
prompt.md     # The prompt to run
```

## plugin.yaml Schema
```yaml
name: plugin-name
description: What it does
trigger: patrol          # When to run (patrol, on-nudge, on-shutdown)
tier: haiku              # Model tier (haiku, sonnet, opus)
input: polecat-list      # What context to gather (polecat-list, session-capture, etc)
```

## Execution
1. Witness reads plugins from directory
2. For each plugin matching current trigger:
   - Gather specified input context
   - Run prompt.md against specified tier
   - Parse output for gt commands
   - Execute commands

## CLI
- `gt plugin list <rig>` - List installed plugins
- `gt plugin run <rig> <plugin>` - Manual run


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


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

## Related

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

Reference: docs/merge-queue-design.md#id-convention

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

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

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

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


Create mol-gastown-polecat derived molecule

Create the standard Gas Town polecat workflow molecule.

## Molecule Definition
\`\`\`markdown
## Molecule: gastown-polecat
Full workflow for Gas Town polecats including binary installation.

Includes: mol-engineer-in-box

## Step: install-binary
After merge is submitted, rebuild and install the local gt binary.
This ensures the latest code is available to all local agents.

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

Needs: submit
\`\`\`

## Why This Molecule
Every polecat that pushes to main should also rebuild the binary.
This ensures the installed gt is always current with main.

## Implementation
1. Add to builtin_molecules.go (after Includes support lands)
2. Update SeedBuiltinMolecules
3. Run gt molecule seed

## Acceptance
- [ ] mol-gastown-polecat exists
- [ ] Includes all engineer-in-box steps
- [ ] Adds install-binary step after submit
- [ ] Can be used with gt spawn --molecule

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


Patrol step: check parked molecules for unblock

Add patrol step to Deacon for checking parked molecules:

```yaml
- step: check-parked-molecules
  action: |
    For each molecule with:
      - status: in_progress
      - assignee: null
      - has step with external: blocked_by
    Check if external deps are now satisfied.
    If yes: spawn polecat to resume the molecule.
```

This automates the resume process - no manual intervention needed when
upstream dependencies ship.

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

Depends on: gt-in3x (spawn --continue)
Priority: P3 (future automation, not required for launch)


gt mail read: Support numeric indices for message ID

Allow 'gt mail read 1' to read the first message in inbox.

Current behavior requires full message ID like 'msg-abc123'.
Should support:
- Numeric index: 'gt mail read 1' reads first/newest message
- Partial ID match: 'gt mail read abc' matches 'msg-abc123'

This is a UX improvement - agents frequently type 'gt mail read 1'.


Update prompts.md: Engineer role and templates

Update docs/prompts.md with Engineer role:

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


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
```

Add unit tests for daemon package

The daemon package has no unit tests. Need tests for:
- Config and state serialization
- Session name pattern matching (isWitnessSession)
- Lifecycle request parsing
- Identity to session mapping


gt molecule current: Show what agent should be working on

Query what an agent identity is supposed to be working on via breadcrumb trail.

## Command
```bash
gt molecule current <identity>
gt molecule current gastown/furiosa
gt molecule current deacon
```

## Logic
1. Find handoff bead for identity (pinned bead titled "<role> Handoff")
2. Parse attachment field → molecule ID
3. If no attachment → "naked" (no active molecule)
4. If attached → load molecule, find current step:
   - bd ready --parent=<mol-id> → next unblocked step
   - Or first in_progress step

## Output
```
Identity: gastown/furiosa
Handoff:  gt-8v2 (Furiosa Handoff)
Molecule: gt-mol-abc (mol-polecat-work)
Progress: 3/8 steps complete
Current:  gt-mol-abc.4 - verify-tests
```

Or if naked:
```
Identity: gastown/angharad
Handoff:  gt-9x1 (Angharad Handoff)
Molecule: (none attached)
Status:   naked - awaiting work assignment
```

## Use Cases
- Mayor checking what polecats are doing
- Witness verifying polecat progress
- Debug: "why isnt this polecat working?"
- Deacon patrol: track all agent states

gt spawn: add --polecat flag for explicit worker selection

Currently gt spawn requires positional arg format:
```
gt spawn gastown/Angharad --issue gt-xyz
```

But I tried the more intuitive flag form:
```
gt spawn --issue gt-xyz --polecat Angharad
```

This failed with 'unknown flag: --polecat'.

The flag form is more discoverable and consistent with other commands. Add --polecat flag as alternative to positional arg.


Merge: gt-5af.6

Phase 5.1: Document ephemeral architecture

Update docs with ephemeral molecule architecture.

## Files to Update

### docs/architecture.md
- Add Ephemeral Molecules section
- Diagram: Proto → Ephemeral → Digest flow
- Explain inversion of control for summaries

### docs/molecules.md (new or update)
- Proto molecule catalog
- Ephemeral vs main beads
- Molecule lifecycle
- Summary generation guidelines

### Agent CLAUDE.md files
- Polecat: molecule workflow protocol
- Deacon: patrol cycle pattern
- Witness: patrol cycle pattern
- Refinery: patrol cycle pattern

## Key Concepts to Document

1. Everything is a molecule
2. Orchestration molecules are ephemeral
3. Only digests reach main beads
4. Agents generate their own summaries
5. Crash recovery via ephemeral persistence


Merge: gt-a95

branch: polecat/Ace

Session cycling UX: smooth transitions via TUI wrapper

## Problem

Current CLI agent session cycling is painful:
- Shell → CC starts → priming → context loads → ready → work → exit/crash → repeat
- Each cycle is 30-60 seconds of cold boot
- No continuity between shell and agent's inner state
- Raw "session not running, starting..." loop is the baseline

## GGT Advantages (already have)

- Beads: Work state survives session death completely
- Mail: Handoff notes from past-self to future-self
- Prime commands: Structured context reload

## Gap: Transition Mechanics

Ideas to explore when actively using CLI:

1. **In-band cycling** - `/restart` or `/cycle` command, agent handles own restart without dropping to shell

2. **Hot standby** - TUI maintains pre-warmed session in background, switch to already-primed agent

3. **Persistent wrapper** - Bubbletea TUI stays running across session cycles, CC sessions come/go inside it

4. **Session pooling** - Keep 2-3 primed sessions ready, never wait for cold start

## Deferred

Deliberately P4 until we're actively using the simpler CLI and feel the pain firsthand.


Implement gt harness create command

Add scaffolding command to create a new harness:
- gt harness create [path]
- Creates config/, mayor/, .beads/redirect (optional)
- Optionally initializes git
- Generates CLAUDE.md with Mayor role
- Could also offer a template repo alternative


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


Town Doctor molecule for harness health checks

Create a Town Doctor molecule that any Gas Town agent can run to diagnose and repair harness issues.

## Concept

Instead of just `gt doctor` as a CLI command with hardcoded checks, create a **molecule** (checklist workflow) that:
- Any agent (Mayor, Witness, Polecat) can instantiate
- Walks the agent through diagnostic steps
- Agent uses judgment to fix issues found
- Works as a structured troubleshooting guide

## Why a Molecule?

1. **Agent-driven**: The agent running it becomes "the doctor" temporarily
2. **Extensible**: Add new checks by updating the molecule, not code
3. **Contextual**: Agent can reason about issues, not just run scripts
4. **Self-healing**: Agent can fix problems it finds, not just report them

## Proposed Checks (molecule steps)

1. Verify harness structure (mayor/, .beads/, CLAUDE.md exist)
2. Validate config files (town.json, rigs.json parse correctly)
3. Check beads health (bd doctor, redirect validity)
4. Verify git state (clean working tree, proper remotes)
5. Check rig integrity (each registered rig exists, has config.json)
6. Validate agent clones (mayor/rig/, refinery/rig/ exist and are valid)
7. Check for orphaned worktrees/branches
8. Verify daemon state (if running)

## Integration

- `gt doctor` could instantiate the molecule for the current agent
- Or agent can run `bd ready` and pick up doctor tasks when prioritized
- Results logged to beads for audit trail

Design: Polecat Beads write access

Design for granting polecats direct beads write access.

## Background

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

## Benefits

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

## Complications

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

## Subtasks (implementation)

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

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

gt polecat remove --all: bulk polecat teardown

Currently gt polecat remove only accepts one polecat at a time. Need bulk operations:

## Requested
- `gt polecat remove gastown --all` - remove all polecats from a rig
- `gt polecat remove gastown/A gastown/B ...` - remove multiple by name

## Context
After a swarm completes, tearing down 20 polecats one at a time is tedious.
Ephemeral workers should be easy to create and destroy in bulk.

## Related

Update Refinery to use Beads merge queue

Replace branch discovery with Beads queue in the Refinery module:

Current (internal/refinery/manager.go):
- Scans for polecat/* branches
- Creates MR objects on-the-fly

New:
- Pull from Beads: bd ready --type=merge-request
- Process each MR
- Close with merge commit: bd close <id> --reason="Merged at <sha>"
- Handle failures: bd update <id> --status=blocked --reason="..."

The Engineer (agent) becomes Beads-native.
The Refinery (module) provides the infrastructure.


Workspace cleanup: preflight and postflight

Workspace preflight and postflight commands for clean state management.

## Preflight
```
gt preflight [--rig <rig>] [--dry-run]
```

Run before starting batch work:
1. Clean stale mail in inboxes
2. Check for stuck workers (warn)
3. Check rig health (polecats, refinery)
4. Verify git state is clean
5. Run bd sync to ensure beads current

## Postflight
```
gt postflight [--rig <rig>] [--archive-mail] [--dry-run]
```

Run after batch work completes:
1. Archive old mail with --archive-mail
2. Clean up stale integration branches
3. Sync beads
4. Report on rig state

## Implementation
```go
func Preflight(rigName string, dryRun bool) (*PreflightReport, error)
func Postflight(rigName string, opts PostflightOptions) (*PostflightReport, error)
```

## Report Structures
```go
type PreflightReport struct {
    MailCleaned    int
    RigHealthy     bool
    StuckWorkers   []string
    Warnings       []string
}

type PostflightReport struct {
    MailArchived   int
    BranchesCleaned int
    Warnings       []string
}
```

## Note

These are workspace maintenance commands, not tied to "swarm" lifecycle. Run them anytime to keep the rig clean.

## Acceptance Criteria
- [ ] Preflight cleans stale state
- [ ] Postflight archives old mail
- [ ] Both have --dry-run mode
- [ ] Clear reports of actions taken


Spawn --molecule integration

Implement gt spawn --molecule flag for molecule-based polecat workflows.

Usage: gt spawn --issue gt-xyz --molecule mol-gastown-polecat

Behavior:
1. Validate molecule exists and is well-formed
2. Create molecule instance (child beads) under the issue
3. Find first ready step(s) in the instance
4. Spawn polecat with first ready step as initial work

Implementation:
1. Add --molecule flag to spawn command
2. Call molecule.Instantiate()
3. Query ready steps from instance
4. Pass first ready step to polecat context

Files: internal/cmd/spawn.go

Acceptance:
- --molecule flag works
- Creates proper molecule instance
- Polecat starts on first ready step
- End-to-end test with actual polecat


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

    // 1. Parse WorkRequest
    // 2. Clone/pull repo
    // 3. Start Claude on issue
    // 4. Stream WorkEvents as NDJSON
    // 5. Return WorkResult
}
```

## Streaming Response

```go
func (s *WorkServer) streamEvents(w http.ResponseWriter, events <-chan WorkEvent) {
    flusher, _ := w.(http.Flusher)
    encoder := json.NewEncoder(w)
    for event := range events {
        encoder.Encode(event)
        flusher.Flush()
    }
}

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.


Crew workers getting wrong CLAUDE.md (shows Refinery)

## Problem

Crew workers (emma, dave) have CLAUDE.md that says they're the Refinery.

## Evidence

```
$ head -5 /Users/stevey/gt/beads/crew/emma/CLAUDE.md
# Claude: Beads Refinery
You are the **Refinery** for the **beads** rig...
```

## Expected

Should use crew.md.tmpl which correctly says:
```
# Crew Worker Context
You are a **crew worker** - the overseer's (human's) personal workspace...
```

## Impact

- Crew workers have wrong identity in static context
- `gt prime` correctly outputs crew context, but CLAUDE.md conflicts
- Confusing role information

## Fix

Check `gt crew create` or whatever populates CLAUDE.md for crew workers.


Merge: gt-3x1.3

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


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


Rollback support: gt mq revert for problematic merges

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

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

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

Track revert in MR metadata for audit trail.

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


gt crew status: Show workspace status

Implement 'gt crew status [<name>]' command:
- Show session state (running/stopped)
- Show git status (branch, uncommitted changes, unpushed)
- Show last commit info
- Show mail inbox status (unread count)
- If no name given, show all crew workers


Phase 2.3: Polecat CLAUDE.md molecule workflow protocol

Update polecat prompting for molecule-based work.

## CLAUDE.md Updates

Add section on molecule workflow:

```markdown
## Molecule Workflow

When assigned a molecule (check gt prime output):

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

### Summary Guidelines

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

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


Cross-project dependency workflow (Gas Town side)

Gas Town integration for cross-project dependencies.

## Components
- gt-zniu: gt park command (park molecule on external dep)
- gt-in3x: gt spawn --continue (resume parked molecule)
- gt-5uf3: Patrol auto-resume (future)

## Design Doc
See: docs/cross-project-deps.md

## Depends on Beads
- bd-h807: Cross-project dependency support (epic)

## Launch Plan
Phase 1 (launch): gt park + gt spawn --continue (manual resume)
Phase 2 (later): Patrol auto-resume

Work on ga-lzh: Add gt witness attach command. Allow attaching to witness session for a rig, similar to gt mayor attach. When done, submit MR (not PR) to integration branch for Refinery.


Inconsistent error wrapping patterns

Error handling is inconsistent across the codebase:

1. Some functions use fmt.Errorf with %w for wrapping, others don't
2. return nil, nil patterns (40+ occurrences) sometimes represent 'not found' and sometimes 'error but continue' - should use sentinel errors
3. Some places return nil for errors when they should propagate them

Examples of nil,nil that might need review:
- internal/git/git.go:272, 308
- internal/crew/manager.go:227
- internal/witness/manager.go:517, 523, 530, 775
- internal/beads/beads.go:225, 492


Plugin: Plan-to-Epic converter

## Purpose

Help users create beads epics from various planning inputs.

## Inputs
- Markdown task lists
- GitHub issues
- Linear/Jira exports
- Free-form descriptions
- Existing beads epics

## Output
- Beads epic with properly structured children
- Dependencies set for wave ordering
- Priorities assigned
- Ready for `gt spawn --epic <id>`

## Implementation Options

### Option A: CLI Tool
```bash
gt plan import --from github --repo owner/repo --label batch-candidate
gt plan import --from markdown tasks.md
gt plan structure <epic-id>  # analyze and add dependencies
```

### Option B: Plugin Agent
A plugin at `<rig>/plugins/plan-oracle/` that:
- Receives planning requests via mail
- Analyzes scope and requirements
- Creates structured beads epic
- Sets dependencies based on analysis

### Option C: Interactive Mode
```bash
gt plan create
# Walks through questions, creates epic interactively
```

## Axiom

As stated: 'The Planning phase should end in the creation of a workable Beads plan.'

This plugin bridges the gap between human planning and machine-executable work.

## Priority

P2 - Nice to have for MVP. Manual epic creation works for now.

## Note

No "swarm IDs" - output is just a beads epic with children. Workers process it independently.

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.


Add gt hook command (wrapper for bd hook)

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

## Usage

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

## Implementation

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

## Why gt wrapper?

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

## Related

- bd hook command (implemented by Dave)
- Chemistry UX design: gastown/mayor/rig/docs/chemistry-design-changes.md


Swarm learning: Spawn should auto-notify polecats

town spawn assigns issues but doesn't notify polecats. Required separate 'town session send' to inject prompts. This should be one atomic operation - spawn assigns AND pokes the polecat to start working.


town handoff command (optional)

CLI commands for session handoff workflow (optional convenience).

## Commands

### gt handoff
Generate handoff interactively.
```
gt handoff [--send]
```
- Collects current state (status, inbox, beads)
- Prompts for additional notes
- --send: Mail to self and exit

### gt resume
Check for and display pending handoff.
```
gt resume
```
- Checks inbox for handoff message
- Displays formatted handoff if found
- Suggests next actions

## Implementation

These are convenience wrappers. The same workflow can be done manually:
```bash
# Manual handoff
town status > /tmp/handoff
town inbox >> /tmp/handoff
bd ready >> /tmp/handoff
# Edit and send
town mail send mayor/ -s "Session Handoff" -f /tmp/handoff
```

## Priority

P2 - Optional. Manual workflow works fine. Nice to have for UX.

## Notes

Part of session cycling workflow designed in gt-u82.


gt park command for parking molecules on external deps

Add `gt park` command for when polecat hits external dependency:

```bash
gt park --step=gt-mol.3 --waiting="beads:mol-run-assignee"
```

This command:
1. Adds blocked_by: external:beads:mol-run-assignee to the step
2. Clears assignee on the step
3. Clears assignee on molecule root
4. Sends handoff mail to self with context
5. Shuts down polecat session

The molecule enters "parked" state (derived: in_progress + no assignee + blocked step).

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

Depends on Beads: bd-om4a (external: blocked_by support)


Worker prompting: Beads write access

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

## Beads Access Section for Prompting

```markdown
## Beads Access

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

### Quick Reference

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

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

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

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

### When to Create Issues

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

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

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

### Beads Sync Protocol

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

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

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

## Implementation

Add to AGENTS.md.template polecat section.


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


mol-outpost-assign: Intelligent work routing to outposts

The federation design shows outposts.yaml with a static policy section. Simple preference ordering is fine as config, but intelligent work routing should be a molecule.

Current static approach:
```yaml
policy:
  default_preference: [local, gce-burst, cloudrun-burst]
```

Cases requiring cognition:
- "This is a long-running research task, route to VM not CloudRun"
- "This touches sensitive code, keep local"
- "These 5 issues are related, batch them to same outpost"
- "CloudRun cost is high today, prefer local even if slower"

## Molecule: outpost-assign
Intelligent work-to-outpost routing.

## Step: classify-work
Analyze the issue/work item:
- Expected duration (quick fix vs multi-hour)
- Resource requirements
- Sensitivity/security tier
- Related work (same epic?)

## Step: check-capacity
Query outpost status:
- Current load on each
- Cost accrued today
- Health status

## Step: select-outpost
Choose optimal outpost based on:
- Work classification
- Capacity/cost
- Policy constraints
Needs: classify-work, check-capacity

## Step: emit-assignment
Record decision in beads for audit.
Needs: select-outpost

## Notes
- This molecule is invoked by Mayor/Witness when spawning
- Simple cases can short-circuit to static policy
- Full analysis only for ambiguous cases


Add no-PR instructions to mol-polecat-work at two points

Update mol-polecat-work in builtin_molecules.go to explicitly forbid GitHub PRs.

## Two Points to Add Instructions

### 1. submit-work step
When polecat is ready to submit:
- Push branch to origin
- Create beads merge-request issue
- DO NOT use gh pr create or GitHub PRs

### 2. CLAUDE.md polecat context
Add to polecat role instructions:
- Never use gh pr create
- Never create GitHub pull requests
- The Refinery processes merges via beads MR issues

## Why Two Points
- Molecule step description guides the workflow
- CLAUDE.md reinforces at context level
- Belt and suspenders approach

## Implementation
1. Update PolecatWorkMolecule() submit-work step description
2. Update prompts/roles/polecat.md with explicit prohibition

Related: gt-44wh (general no-PR bug)


File locking for concurrent access

Add file locking for concurrent access safety.

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

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

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

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

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

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

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

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

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

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

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.


gt mq list shows empty when MRs exist

The gt mq list command returns empty results even when merge requests exist in the queue.


Design: Plugin architecture (agents-as-plugins)

Plugin system where plugins are just additional agents with identities, mailboxes, and beads access. See docs/architecture.md Plugins section. No special framework - just directory conventions and mail-based invocation.


Molecule composition: Includes directive

Add support for molecule composition via the Includes directive.

## Format
\`\`\`markdown
## Molecule: derived-name
Includes: mol-base-molecule

## Step: additional-step
Additional instructions here.
Needs: step-from-base
\`\`\`

## Implementation
1. Add \`Includes:\` parsing to ParseMoleculeSteps()
2. Resolve included molecule by ID
3. Merge steps from included molecule
4. Allow new steps to depend on included steps
5. Support multiple includes (polymers)

## Files to modify
- internal/beads/molecule.go
- internal/beads/molecule_test.go

## Acceptance
- [ ] Parse Includes directive
- [ ] Resolve and merge included steps
- [ ] Dependencies across molecules work
- [ ] Multiple includes supported
- [ ] Tests cover composition scenarios


Plugin: plan-oracle (work decomposition)

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