beads: Stop searching upward when .beads found

## Problem

When running bd commands in a nested directory structure with multiple .beads directories, bd shows a confusing warning:

```
╔══════════════════════════════════════════════════════════════════════════╗
║ WARNING: 2 beads databases detected in directory hierarchy              ║
╠══════════════════════════════════════════════════════════════════════════╣
║ Multiple databases can cause confusion and database pollution.          ║
║                                                                          ║

╚══════════════════════════════════════════════════════════════════════════╝
```

## Why This Is Wrong

In Gas Town, nested .beads directories are **intentional and necessary**:
- Town level: /Users/stevey/gt/.beads (mail, town-level issues)
- Rig level: /Users/stevey/gt/gastown/.beads (gastown project issues)
- Worker level: polecats have their own beads in worktrees

These are **unrelated** beads instances for different scopes. They should never be consolidated.

## Expected Behavior

When bd finds a .beads directory, it should:
1. Use that directory (closest ancestor wins)
2. **Stop searching upward** - do not look for parent .beads directories
3. **No warning** about multiple databases

## Current Behavior

bd searches all the way up to root, finds all .beads directories, and warns about "multiple databases" even though they are separate, intentional instances.

## Fix

In the database discovery code, stop the upward search as soon as a .beads directory is found. The first .beads found is the one to use, and parent directories are out of scope.

## Note

This is a beads issue, filed here for tracking. Should be implemented in the beads codebase.

Merge: gt-h6eq.7

branch: polecat/dag
target: main
source_issue: gt-h6eq.7
rig: gastown


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.


survey-workers

List polecats and categorize by status.

```bash
gt polecat list <rig>
```

Needs: load-state


Advice operators: before, after, around

Implement Lisp-style advice operators for molecules:
- before(target, step) - insert step before target
- after(target, step) - insert step after target
- around(target, wrapper) - wrap target with before/after

Support glob patterns for targeting (*.implement, shiny.*, etc).


Document crew worker patrol integration

Document how mol-ready-work integrates with crew worker workflow. Cover: starting the patrol, patrol vs normal operation, backlog configuration, handoff mechanics, discovered work handling. Update CLAUDE.md with patrol section.


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


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'.


Witness: Handle LIFECYCLE work-merged mail

Witness should process the `LIFECYCLE: work merged` notification from Refinery.

## Implementation

1. In Witness mail processing, add handler for subject containing "LIFECYCLE: work merged"
2. Parse worker name from mail body
3. Update polecat state to `merged` (new state - see sibling task)
4. Log completion for metrics
5. Worktree is now eligible for cleanup on next gc cycle

## Acceptance
- Witness correctly parses and handles work-merged mail
- Polecat state updated to merged
- No action taken if polecat already cleaned up (idempotent)


Implement pinned beads for handoff state

Add pinned bead support to beads:
- Pinned beads never close, only update
- Use for persistent state like Refinery handoffs
- bd create --pinned flag
- bd list --pinned to find them
- Update description to change state


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


Work reconciliation module

Port reconcile.py work verification to Go.

## Purpose

Verify assigned issues are completed before landing.

## Interface

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

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

## Logic

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

## Handling Incomplete Work

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

## Reference

PGT: swarm/reconcile.py


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.


ensure-beads-witness

Start the beads rig Witness.

## Action
```bash
gt witness start beads
```

## Verify
1. Session exists: `tmux has-session -t beads-witness 2>/dev/null`
2. Not stalled: `gt peek beads/witness` does NOT show "> Try" prompt
3. Heartbeat fresh: Last patrol cycle < 5 min ago

## OnStall
```bash
gt nudge beads/witness "Start patrol."
sleep 30
# Re-verify
```

## OnFail
Log error. Rig polecats will be unmonitored until Witness recovers.


Polecat template: simplify completion section to just 'gt done'

Completion section lists multiple options (gt done, gt handoff, bd sync). Should just say 'gt done' with succinct guidance on when bd sync is needed. Remove the alternatives that cause confusion.


Polecat mood command and status line display

CLI and status line support for polecat mood.

## CLI Command
```
gt polecat mood <name> <emoji>   # Set mood
gt polecat mood <name>           # Get mood
```

Sets GT_MOOD environment variable in the polecat's tmux session.

## Status Line Integration
Update runWorkerStatusLine() to read mood:
```go
mood, _ := t.GetEnvironment(session, "GT_MOOD")
if mood != "" {
    icon = mood  // Use mood emoji instead of default
} else {
    icon = AgentTypeIcons[AgentPolecat]  // Fallback to 😺
}
```

## Storage
Mood stored in tmux session environment (ephemeral, per-session).
No persistence needed - mood is reassessed each patrol cycle.

Depends on: gt-u818 (plugin system)


gt mq list shows empty when MRs exist

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


working

Actively working. Monitor for stuck.

The polecat is processing its assigned issue ({{issue}}).
Monitor via peek. Watch for:
- Progress on commits
- Status updates in beads
- SHUTDOWN mail when done

Wait for SHUTDOWN signal from the polecat.
Variables: {{polecat}}, {{issue}}


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.


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


Update rig init to create refinery as worktree

Modify rig initialization to create refinery as a git worktree instead of a separate clone.

## Changes
- internal/rig/init.go or similar - change refinery setup
- Create worktree at <rig>/refinery/ with branch 'refinery'
- Remove clone logic for refinery
- Update any path assumptions

## Considerations
- Refinery worktree should track main (or its own branch?)
- May need to handle existing rigs (migration path)


TIDY UP: Your previous work (gt-odvf: bd mol CLI docs) wa...

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


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


Refinery tmux status: show merge queue length

Add refinery-specific status line showing:
- MQ length (pending merges)
- Currently processing item (if any)
- Maybe: success/failure counts

Implement in runRefineryStatusLine() in internal/cmd/statusline.go


save-state

Update handoff bead with new state.

Persist nudge counts and pending actions.

Needs: execute-actions


inbox-check

Process witness mail: lifecycle requests, help requests.

```bash
gt mail inbox
```

Handle by message type:
- LIFECYCLE/Shutdown: Queue for pre-kill verification
- Blocked/Help: Assess if resolvable or escalate
- HANDOFF: Load predecessor state
- Work complete: Verify issue closed, proceed to pre-kill

Record any pending actions for later steps.
Mark messages as processed when complete.


Document how to configure a Gas Town Harness

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


Merge: gt-svi.1

type: merge-request
branch: polecat/Max
target: main
source_issue: gt-svi.1
rig: gastown


Merge conflicts: Buzzard/mq-status, Dementus/harness-docs


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?


gt done: Missing command referenced in polecat docs


gt crew at/attach: Start session in crew workspace

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


bd close hooks: context check and notifications

Add hook system to bd close for context checking and notifications.

## Concept

Register hooks that run on every bd close:

# .beads/config.yaml
hooks:
  on_close:
    - command: 'gt context-check'
    - notify: 'Next step ready'

## Use cases

### Context check on close
After closing a step, check if context is getting full.
If >80%, output warning suggesting session cycling.

### Next step notification
Automatically show next ready step (complements --continue).

### Custom actions
User-defined scripts for workflow automation.

## Hook types

- command: Run shell command with env vars (BEAD_ID, BEAD_TITLE, etc)
- notify: Send message to agent
- webhook: POST to URL (future)

## Integration with context detection

The context-check hook could:
1. Capture tmux pane (if in tmux session)
2. Estimate context usage (turn count, output length)
3. If high, output: 'Context at ~85%. Consider cycling.'

## Priority
P2 - nice to have, not blocking launch.

## Related
- gt-qswb (bd mol current)
- gt-fly0 (bd close --continue)


Witness swarm landing protocol

Witness responsibilities for swarm landing cleanup.

## Trigger

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

## Landing Protocol

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

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

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

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

## Code at Risk Handling

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

## Reference

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


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.


Integration branch management for swarms

Manage integration branches for swarm merging strategy.

## Branch Naming

- Integration branch: `integration/<swarm-id>` (e.g., integration/sw-1)
- Worker branches: `<swarm-id>/<polecat>` (e.g., sw-1/Toast)

## Operations

```go
// Create integration branch at swarm start
func (m *SwarmManager) CreateIntegrationBranch(swarmID string) error
// - Creates from BaseCommit
// - Pushes to origin

// Merge worker branch to integration
func (r *Refinery) MergeToIntegration(swarmID, workerBranch string) error
// - Fetches worker branch
// - Merges to integration/<swarm-id>
// - Handles conflicts (semantic merge)

// Land integration to main
func (r *Refinery) LandToMain(swarmID string) error
// - Merges integration/<swarm-id> to main
// - Pushes to origin
// - Triggers cleanup

// Cleanup branches after landing
func (m *SwarmManager) CleanupBranches(swarmID string) error
// - Deletes integration/<swarm-id> (local + remote)
// - Deletes all <swarm-id>/<polecat> branches
```

## All Workers Same Base

When swarm starts:
1. Record current main HEAD as BaseCommit
2. All polecats branch from BaseCommit
3. Integration branch also starts at BaseCommit

This ensures clean merges within the swarm.

## Reference

PGT: ephemeral.py (create_integration_branch, merge_integration_to_main)


Crew workers: design documentation and remaining work

## Summary

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

## Current Implementation

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

### Crew vs Polecat

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

## Known Bugs

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

## Potential Enhancements

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


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


Implement mol bond command for dynamic child molecules

Add 'gt mol bond' command that creates child molecules at runtime with variable substitution.

Usage from mol-witness-patrol survey-workers step:
```bash
bd mol bond mol-polecat-arm $PATROL_WISP_ID \
  --ref arm-$polecat \
  --var polecat_name=$polecat \
  --var rig=<rig>
```

This creates child wisps like patrol-x7k.arm-ace with variables expanded.

Implementation:
1. Add 'bond' subcommand to mol command
2. Accept: proto ID, parent ID, --ref for child suffix, --var key=value pairs
3. Call InstantiateMolecule with Context map populated from --var flags
4. Return created child ID

Critical for Christmas Ornament pattern - without this, Witness cannot spawn per-polecat inspection arms.


Plugin/molecule catalog integration design

Two currently independent systems:
1. Disk-based plugins (~~/gt/plugins/) - Deacon patrol extensions
2. Molecule catalog (protos in beads) - bd pour/wisp/bond

Investigate integration points:
- User-contributed molecules bonded to catalog
- Dynamic molecule attachment during execution (e.g., 'attach security sniffer because we noticed condition X')
- How plugins could contribute protos
- How protos could trigger plugins

Not blocking launch. Future design investigation.


Runtime dynamic expansion (for-each)

Implement runtime expansion for discovered work:
- on-complete: for-each: output.items
- Bonds N instances based on step output
- Christmas Ornament pattern support

Enables dynamic survey-workers → polecat-arm bonding.


Deacon patrol banners: visual feedback on atom transitions

Print large ASCII banners when transitioning between patrol atoms.

## Problem

When the deacon progresses through patrol atoms (steps), there is no visual feedback.
The operator cannot easily see what the deacon is doing without reading the full output.

## Desired Behavior

Print banners on step start and completion:

  INBOX-CHECK - Checking for lifecycle requests, escalations, timers
  INBOX-CHECK COMPLETE - Processed 3 messages, 0 lifecycle requests

## Benefits

1. Scanability: Operator can glance at tmux and see what is happening
2. Progress tracking: Easy to see where in the patrol loop we are
3. Debugging: Clear demarcation between steps for troubleshooting

## Implementation Options

1. In deacon CLAUDE.md: Instruct agent to print banners
2. gt patrol step start/end: Commands that print banners
3. bd mol step hooks: Automatically on step transitions

## Related

- gt-rana: Patrol System


gt mq integration create: create integration branch for epic

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

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

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

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

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


gt sling: nudge crew/mayor if session is running

When slinging to crew or mayor, if they have an active tmux session, send a nudge notification so they know work has landed on their hook.

Currently only slingToPolecat nudges (lines 514-521 in internal/cmd/sling.go).

Missing nudge in:
- slingToCrew (line ~669)
- slingToMayor (line ~876)

NOT applicable to patrol-based agents (witness, refinery, deacon) - they run on cycles and pick up work via hook check, not interactive nudge.

Implementation:
1. For crew: need to determine session name (e.g., gastown-crew-max)
2. Check if session running via tmux
3. If running, call t.NudgeSession() with appropriate message


gt mol command tree: status, catalog, burn, squash

Add gt mol subcommand as agent-side API for molecule operations.

Commands needed:
- gt mol status - What's on my hook? (pinned molecule, current step, progress)
- gt mol catalog - List available protos (delegate to bd mol catalog)
- gt mol burn - Burn current attachment
- gt mol squash - Squash current molecule to digest

This completes the agent-side API and makes the docs (sling-design.md, propulsion-principle.md) match reality.

Blocks: deacon.md.tmpl update (can't use gt mol status until it exists)


check-refinery

Ensure the refinery is alive and processing merge requests.

Needs: inbox-check


Convert MR queue to wisp storage

MR queue should use wisp storage (.beads-wisp/) instead of durable beads.

## Design (Simplified)

With refinery as worktree, polecats and refinery share the same machine. No cross-machine MR coordination needed. Wisps are the natural fit.

### Storage
- Location: `.beads-wisp/mq/<mr-id>.json`
- Format: Same MRFields structure (branch, target, source_issue, worker, rig)
- Lifecycle: Create on submit, delete after merge

### Code Changes

1. **MR Creation** (done.go, mq_submit.go)
   - Write to `.beads-wisp/mq/` instead of `bd create --type=merge-request`
   - Generate ID: `mr-<timestamp>-<random>` or similar

2. **Refinery Query** (refinery/manager.go, engineer.go)
   - Read from `.beads-wisp/mq/` directory
   - List files, parse JSON, process in order

3. **Cleanup**
   - Delete MR file after successful merge
   - On failure, leave file (refinery retries)

### What Stays in Beads
- Source issues (the work being merged) - still tracked in beads
- Merge commits reference source issue ID
- `bd close <issue>` still happens on merge

### Benefits
- No sync overhead for transient MR state
- Simpler model (file per MR, delete when done)
- Consistent with wisp philosophy (ephemeral operational state)

### Not Needed
- Digest squashing (MRs are deleted, not accumulated)
- Cross-machine visibility (single-machine architecture)


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


detectSender() doesn't recognize crew workers

## Problem

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

## Current Code (line 445)

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

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

## Symptom

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

## Fix

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

## Also Check

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


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.


gt swarm start: Does not spawn polecat sessions

gt swarm start marks swarm as 'active' but doesn't start any polecat sessions.

Repro:
1. gt swarm create gastown --epic gt-hw6 --worker Toast --worker Nux
2. gt swarm start gt-hw6
3. gt session list - shows no new sessions

Expected: Polecat sessions should start for each worker.
Actual: No sessions started, workers sit idle.


Add agent abstraction layer to support non-Claude agents

Currently Gas Town hardcodes 'claude --dangerously-skip-permissions' throughout the codebase for spawning agents. We should add an abstraction layer to support other AI agents (e.g., Gemini CLI, OpenAI agents, local models).

Locations that spawn Claude:
- internal/cmd/mayor.go:131
- internal/cmd/deacon.go:150
- internal/cmd/witness.go:280
- internal/cmd/crew.go (multiple locations)
- internal/cmd/up.go:190, 229
- internal/session/manager.go:146
- internal/refinery/manager.go:207

Suggested approach:
1. Create an agent package with an interface
2. Add configuration for agent type in town/rig config
3. Replace hardcoded claude commands with agent.Spawn() calls
4. Support agents: claude, gemini, openai, local (ollama, etc.)

Integration test: agent waits for CI via gate

End-to-end test of the gate workflow.

## Test Scenario
1. Agent creates gate: bd gate create --await gh:run:123 --timeout 5m --notify beads/dave
2. Agent writes handoff and exits
3. Deacon patrol checks gate condition
4. (Mock) GitHub run completes
5. Deacon notifies waiter and closes gate
6. New agent session reads mail and resumes

## Test Requirements
- Mock GitHub API responses
- Test timeout path
- Test multiple waiters
- Verify mail notifications sent

## Moved from beads
Originally bd-rl5t. Tests Deacon patrol which is in gastown.

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)


Phase verbs: pour and wisp commands

Implement the phase transition verbs:
- bd pour <proto> - instantiate as persistent mol
- bd wisp <proto> - instantiate as ephemeral wisp
- Update bd mol bond to inherit phase from target

These replace the current --wisp flag with cleaner verb semantics.


Witness handoff bead state persistence

Implement state persistence for Witness across wisp cycles.

## Problem
Wisps burn between cycles, but Witness needs to remember:
- Which workers have been nudged
- How many times (nudge_count)
- When was last nudge
- Last observed activity

## Solution
Witness handoff bead with worker_states field:

```json
{
  "id": "gt-witness-state",
  "type": "handoff",
  "assignee": "<rig>/witness",
  "pinned": true,
  "worker_states": {
    "furiosa": {
      "issue": "gt-123",
      "nudge_count": 2,
      "last_nudge": "2024-12-22T10:00:00Z"
    }
  },
  "last_patrol": "2024-12-22T10:05:00Z"
}
```

## Implementation
1. On patrol start: bd show <witness-handoff-id> to load state
2. During patrol: update in-memory state
3. On save-state step: bd update to persist
4. State survives wisp burn/squash

## Depends on
- gt-83k0 (mol-witness-patrol definition)


Fetch and conflict check: git operations for MR

Implement git operations for MR processing.

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

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

Polecat state tracking: Add mr_submitted and merged states

Track polecat lifecycle state separate from session state.

## New States

| State | Meaning |
|-------|---------|
| active | Working on assigned issue |
| mr_submitted | MR submitted, waiting for merge |
| idle | No current work, session may be alive |
| merged | Work successfully merged by Refinery |
| retired | Session killed, worktree removed |

## Implementation

1. Add state field to polecat tracking (state.json or beads)
2. `gt polecat update <name> --state=<state>`
3. `gt polecat list` shows state column
4. State transitions:
   - active → mr_submitted (on gt mq submit)
   - mr_submitted → merged (on Refinery notification)
   - merged → retired (on worktree cleanup)

## Acceptance
- Polecat state tracked and queryable
- State transitions happen at correct lifecycle points
- `gt polecat list` shows current state


Polecat template: fix hard-to-parse sentence about persistence

This sentence is hard to parse: 'When in doubt, prefer bd—persistence you don't need beats lost context'. Rewrite for clarity, e.g., 'When in doubt, use bd for tracking - unnecessary persistence is better than lost context.'


MVP Cutover: GGT replaces PGT for batch work

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

## Acceptance Criteria

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

## What Must Work

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

## What Can Be Deferred

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

## Test Plan

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

## Validation

Run one real batch implementing GGT issues using GGT.

## Note

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


gt 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)

Define mol-gastown-boot proto structure

Create the proto molecule definition with all steps.

## Proto Definition

Each step has:
- Title (step name)
- Description with Action/Verify/OnStall/OnFail sections
- Dependencies (Needs: directive)

## Steps

1. ensure-daemon
   - Action: gt daemon status || gt daemon start
   - Verify: daemon PID exists and responding

2. ensure-deacon
   - Action: gt deacon start
   - Verify: session exists, not stalled, heartbeat fresh
   - OnStall: gt nudge deacon/ "Start patrol."

3. ensure-witnesses (parallel container)
   - ensure-gastown-witness
   - ensure-beads-witness
   - Verify each: session exists, not stalled

4. ensure-refineries (parallel container)
   - ensure-gastown-refinery
   - ensure-beads-refinery
   - Verify each: session exists, not stalled

5. verify-town-health
   - Action: gt status
   - Verify: all expected agents shown

## Output

Proto stored in beads as molecule type issue.

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.

Formula versioning and migration strategy

Define how formula versions are managed:
- What does the version field mean? Semver? Integer?
- When a formula changes, what happens to existing protos?
- Do protos track their source formula version?
- Migration path: old proto + new formula = ?
- Backwards compatibility guarantees (if any)

Deferred: post-launch polish


Create Refinery role template

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


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


Epic: Refinery Engineer Autonomy

Make Refinery Engineer fully autonomous:

## Goal
Refinery can run indefinitely, processing all polecat work through merge queue, cycling sessions as needed, without human intervention.

## Key Components
1. Role prompting (CLAUDE.md, templates)
2. Handoff mechanism (pinned beads)
3. Context detection (gt prime)
4. Communication protocol (Witness, Deacon)
5. Future: Merge orchestration plugins

## Success Criteria
- Refinery starts, reads handoff, knows what to do
- Processes merges sequentially with conflict resolution
- Cycles sessions cleanly via Deacon
- Communicates results to Witness
- No work left behind


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)


Work request: gt-976 crew lifecycle support

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

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

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

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

- Dave (beads/crew/dave)


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.
```

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


Refactor: Eliminate state.json, use beads assignee field for polecat state

## Problem

state.json in each polecat worktree duplicates data that should be in beads:
- `issue` field duplicates assignment (should be issue.assignee)
- `state` field duplicates status (derivable from issue.status)
- `name/rig/branch/clone_path` are all derivable from filesystem/git

This violates 'Beads as the data plane' (HOP Decision 001).

## Current State

```json
{
  "name": "Angharad",        // Derivable: basename(cwd)
  "rig": "gastown",          // Derivable: parent dir name
  "state": "working",        // Should be: issue.status
  "clone_path": "/path",     // Derivable: cwd
  "branch": "polecat/X",     // Derivable: git branch
  "issue": "gt-xyz",         // Should be: issue.assignee
  "timestamps": "..."        // Should be in beads history
}
```

## Target State

**Polecat identity**: Derived from worktree path
**Polecat assignment**: `issue.assignee = 'gastown/Angharad'`
**Polecat state**: Derived from issue.status (in_progress = working, closed = done)
**Polecat existence**: Worktree directory exists

## Benefits

1. Single source of truth (no sync issues)
2. Queryable: `bd list --assignee=gastown/Angharad`
3. History tracking via beads
4. Cross-agent coordination via beads sync
5. Simpler code (no state file management)

## Implementation

1. Update `gt spawn` to set issue.assignee instead of writing state.json
2. Update polecat list/status commands to query beads
3. Update Witness to query beads for polecat state
4. Remove state.json read/write code
5. Keep state.json as optional bootstrap cache (perf optimization only)

Guardrail: Verify commits exist before closing polecat issues

When closing an issue that was assigned to a polecat, verify that at least one commit references the issue ID.

## Problem
A polecat can be cleaned up before completing work. If someone then manually closes the issue (or automation does), we lose track that the work was never done.

## Proposed Solution
Add a pre-close check:
```bash
git log --oneline --all --grep='<issue-id>' | head -1
```

If no commits found, warn or block the close.

## Where to Implement
Options:
1. **bd close** - Add --verify flag or make it default for polecat-assigned issues
2. **Witness cleanup** - Verify before clearing assignee
3. **gt polecat done** - Check before marking done

Refinery needs manual restart/handoff mechanism

Refinery sessions can get stuck or need restart. Currently requires manual intervention. Need: 1) gt refinery restart command, 2) Refinery self-handoff on context fill, 3) Auto-recovery from stuck states.


mol-witness-patrol

Per-rig worker monitor patrol loop using the Christmas Ornament pattern.

The Witness is the Pit Boss for your rig. You watch polecats, nudge them toward
completion, verify clean git state before kills, and escalate stuck workers.

**You do NOT do implementation work.** Your job is oversight, not coding.

## The Christmas Ornament Shape

This molecule uses dynamic bonding to create inspection arms per-polecat:

```

## Phases

### PREFLIGHT (fixed steps)
1. inbox-check - Process lifecycle requests, help messages
2. check-refinery - Ensure MQ is alive and processing
3. load-state - Read persistent state (nudge counts, etc.)

### DISCOVERY (spawns dynamic arms)
4. survey-workers - List polecats, bond mol-polecat-arm per polecat
5. run-plugins - Bond mol-plugin-runner for each witness plugin

### CLEANUP (gate + fixed steps)
6. aggregate - GATE: WaitsFor all arms + plugins to complete
7. save-state - Persist nudge counts, action log
8. generate-summary - Create digest content
9. context-check - Check if context is high
10. burn-or-loop - Squash/burn wisp, then loop or exit

## Dynamic Arms

Each polecat gets mol-polecat-arm bonded as a wisp child:
- capture - Capture tmux output
- assess - Categorize state (working/idle/error/done)
- load-history - Get nudge counts for this polecat
- decide - Apply nudge matrix
- execute - Take action (nudge/kill/escalate/none)

Arms run in PARALLEL. The aggregate step waits for all to complete.

## Activity Feed

This design enables real-time visibility:

```
[14:32:08] + patrol-x7k.arm-ace bonded (5 steps)
[14:32:09] → patrol-x7k.arm-ace.capture in_progress
[14:32:10] ✓ patrol-x7k.arm-ace.capture completed
[14:32:14] ✓ patrol-x7k.arm-ace.decide completed (action: nudge-1)
[14:32:17] ✓ patrol-x7k.arm-ace COMPLETE
```

## Storage

- Wisp storage: .beads-wisp/ (ephemeral, gitignored)
- Persistent state: witness handoff bead (nudge counts, etc.)
- Digests: Squashed summaries in permanent beads

## Dependencies

- bd-xo1o: Dynamic Molecule Bonding epic (in beads rig)
  - bd mol bond with variable substitution
  - WaitsFor directive for fanout gates
  - Activity feed query

Swarm learning: Session cleanup missing from swarm workflow

## Problem

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

## What Should Happen

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

## GGT Components

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

## Recommendation

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

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


Add compaction recovery protocol to role templates

After context compaction (summarization), agents may be disoriented.

Add guidance to recognize and recover:
- 'If you feel you've lost earlier context or are disoriented, run: gt prime'
- 'This re-injects your role, current work, and pending messages'
- 'It's safe to prime multiple times - it just outputs context'

This is the fallback path when self-check is missed and compaction happens.
Compaction isn't catastrophic if priming is robust.


ensure-daemon

Verify the Gas Town daemon is running.

## Action
```bash
gt daemon status || gt daemon start
```

## Verify
1. Daemon PID file exists: `~/.gt/daemon.pid`
2. Process is alive: `kill -0 $(cat ~/.gt/daemon.pid)`
3. Daemon responds: `gt daemon status` returns success

## OnStall
Daemon startup failed. Try:
```bash
gt daemon stop
sleep 2
gt daemon start
```

## OnFail
Cannot start daemon. Log error and continue - some commands work without daemon.


inspect-workers

Capture output for each working polecat.

```bash
gt peek <rig>/<polecat>
```

Needs: survey-workers


Swarm learning: Beads database locality gap

## PGT Bug (GGT Design Already Correct)

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

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

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


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


Human escalation path design

Flesh out the human escalation mechanism for Gas Town errors. Currently: errors mail Mayor, Mayor startup prompts about escalations. Need: structured escalation channel, escalation severity levels, and clear documentation. All edge cases in molecular algebra can write warnings to this channel.


Built-in molecules: engineer-in-box, quick-fix, research

Create built-in molecules as Beads issues:

## engineer-in-box

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

Full workflow from design to merge.

## Step: design
Think carefully about architecture. Consider:
- Existing patterns in the codebase
- Trade-offs between approaches
- Testability and maintainability

Write a brief design summary before proceeding.

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

## Step: review
Self-review the changes. Look for:
- Bugs and edge cases
- Style issues
- Missing error handling
Needs: implement

## Step: test
Write and run tests. Cover happy path and edge cases.
Fix any failures before proceeding.
Needs: implement

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

## quick-fix

```markdown
id: mol-quick-fix
type: molecule
title: Quick Fix

Fast path for small changes.

## Step: implement
Make the fix. Keep it focused.

## Step: test
Run relevant tests. Fix any regressions.
Needs: implement

## Step: submit
Submit for merge.
Needs: test
```

## research

```markdown
id: mol-research
type: molecule
title: Research

Investigation workflow.

## Step: investigate
Explore the question. Search code, read docs,
understand context. Take notes.

## Step: document
Write up findings. Include:
- What you learned
- Recommendations
- Open questions
Needs: investigate
```

## Storage

Built-in molecules live in `<town>/.beads/` as regular issues.
Created during `gt install` or `bd init`.


gt refinery attach: Attach to refinery session

Add 'gt refinery attach [rig]' command to attach to refinery tmux session.

Mirrors 'gt mayor attach' pattern. If rig not specified, use current rig context.


Town & Rig Management: install, doctor, federation

Reify the Gas Town installation as a first-class concept.

## Goals
- Installable: gt install [path] creates complete installation
- Diagnosable: gt doctor checks and fixes issues
- Federable: Clone town to VMs with central control

## Architecture Reference

See docs/architecture.md for full design, especially:
- Directory structure (Town Level / Rig Level sections)
- Configuration (town.json, rigs.json schemas)
- Key design decisions (visible config dir, decentralized agents)


Formula inheritance trees for organizational policies

Support organizational formula hierarchies where teams extend a company-base-formula. Each team can add required aspects (accessibility audit for frontend, SQL injection scan for backend). Enables policy enforcement across an organization.


gt sling --on flag for wisp scaffolding

Add --on flag to gt sling for applying forms to existing work:
  gt sling shiny gastown/Toast --on gt-abc123

When --on is specified, implies --wisp (scaffolding existing work).
The form shapes execution of the target bead.

Adaptive backoff for daemon heartbeat

Track agent responsiveness and adjust heartbeat frequency.

## Per-Agent State

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

## Strategy Options

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

## Recovery

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

## Benefits

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


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

Update deacon.md.tmpl with correct molecule commands

The deacon prompt references commands that don't exist:
- gt mol bond → should be bd mol run or gt mol arm
- gt mol status → needs gt mol command tree first

Update after gt mol command tree is implemented.

Depends on: gt mol command tree issue


gt install command: Create workspace structure

Create Gas Town workspace structure.

## Command

```
gt install [path]
```

If path omitted, uses current directory.

## Created Structure

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

## Implementation

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

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

## Steps

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

## Error Cases

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

## Templates

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


Refinery as Worktree: Local MR Integration

Move refinery from separate clone to git worktree. Polecats stop pushing to origin - refinery sees their branches locally. MRs become wisps (ephemeral). Only main gets pushed after merge.

## Goals
- Origin stays clean (only main + beads-sync branches)
- No orphaned polecat branches ever
- Simpler mental model for MR coordination
- Faster integration (no network for local MR ops)

## Trade-offs
- Machine crash = redo pending work (acceptable, beads track state)
- Future federation needs different approach (bundles or integration branch)

## Components Affected
- Rig initialization (refinery setup)
- Spawn/polecat workflow (remove origin push)
- Refinery manager (local branch access)
- Documentation (architecture, workflows)
- Molecule templates (remove push instructions)


implement

Implement the solution for gt-qwyu. 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


bd list --parent: filter by parent issue

Add --parent flag to bd list to filter issues by parent.

Example:
```bash
bd list --parent=gt-h5n --status=open
```

Would show all open children of gt-h5n.

Useful for:
- Checking epic progress
- Finding swarmable work within an epic
- Molecule step listing


session stop: --force flag is defined but not used


Fix golangci-lint errcheck warnings (~160 issues)

Running golangci-lint shows ~160 errcheck warnings for unchecked error returns.

Common patterns:
- t.SetEnvironment() return values
- os.WriteFile(), os.RemoveAll()
- MarkFlagRequired() on cobra commands
- Various manager methods

Run: golangci-lint run ./...

Could batch fix with:
1. Add explicit _ = for intentionally ignored errors
2. Handle errors properly where they matter
3. Consider adding //nolint:errcheck for cobra flag setup


P0: Multiple agents can claim same worker identity

Multiple Claude Code sessions running simultaneously all think they are 'dave' on beads/crew/dave. No detection or prevention of identity collision. This breaks the single-agent-per-worker assumption.

## Fix Implemented

1. **Lock Package** (`internal/lock/lock.go`):
   - PID-based lockfile at `<worker>/.gastown/agent.lock`
   - Contains PID, timestamp, session ID, hostname
   - Stale lock detection (checks if owning PID is dead)

2. **Prevention in gt prime**:
   - Workers (crew/polecat) acquire identity lock before loading context
   - If another live process holds the lock, prime fails with clear error
   - Shows lock holder details and resolution steps

3. **Detection with gt agents**:
   - `gt agents check` - scans for collisions and stale locks
   - `gt agents fix` - cleans stale locks
   - JSON output available for patrol tooling

4. **Correction in gt doctor**:
   - New `identity-collision` check
   - `gt doctor --fix` cleans stale locks


load-context

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

Read the assigned issue (gt-test123) and understand the requirements.
Identify any blockers or missing information.

Per-epic config overrides: custom merge settings

Allow per-epic merge configuration overrides.

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

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

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

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


Architecture: beads config and direct landing docs

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


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)


Role templates: rename 'Dependency Trap' to 'Gotchas when Filing Beads'

The 'Dependency Trap' heading is too specific. Rename to something like 'Gotchas when Filing Beads' or 'Beads Filing Tips'. Applies to all role templates (polecat, crew, mayor, witness, refinery, deacon).


Expansion operators: expand and map (macros)

Implement macro-style expansion operators:
- expand(target, template) - apply template to single step
- map(molecule, template) - apply template to all matching steps

Templates use {target} substitution for step references.
Rule of Five is the canonical example.
