gt session start --issue doesn't inject work to prompt

When starting a polecat session with --issue flag:
  gt session start beads/Toast --issue bd-oxgi

The session starts but the polecat doesn't receive the issue context. They sit at the prompt awaiting input. Had to manually nudge them.

Expected: Session start should either nudge or inject the issue context so polecat starts working immediately (propulsion principle).


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.

Deacon session cycling: first step of rounds

First step of every Deacon wake cycle: check if a fresh session is needed.

## Why First

Token costs are quadratic with session length. A Deacon running for hours
accumulates massive context. Better to cycle early and often.

## Implementation

At wake, before doing anything else:

1. Check context budget estimate (conversation turns, tool calls, etc.)
2. If budget is low (e.g., >50% consumed), request cycle:
   - Write handoff mail to self with current state
   - Request lifecycle: cycle via daemon
   - Daemon kills session, starts fresh
   - New session reads handoff mail, continues

## Decision Criteria

- Conversation turns > N (configurable, default 50?)
- Explicit "context feels heavy" signal from Claude
- Time since last cycle > M hours (configurable, default 4?)
- Forced cycle on certain events (e.g., major config change)

## State to Preserve in Handoff

- Current health status
- Pending lifecycle requests (in flight)
- Plugin state (last run times, outcomes)
- Any active timers

## Relation to Daemon

The Deacon requests its own cycle via the same lifecycle mechanism:
```
gt mail send deacon/ -s "LIFECYCLE: deacon/ requesting cycle" -m "..."
```

Daemon sees this, kills gt-deacon session, respawn loop restarts it.


Witness startup: bond mol-witness-patrol on start

Wire up Witness to automatically bond its patrol molecule on startup.

## Desired behavior
On Witness session start:
1. gt prime detects RoleWitness
2. Check for existing in-progress patrol
3. If found: resume from current step
4. If not found: bd mol bond mol-witness-patrol --wisp
5. Output patrol context to agent

## Depends on
- gt-83k0 (mol-witness-patrol definition)
- gt-caih (handoff bead state persistence)

Implement aspect merging across formula chain

Implement merging of aspects when formulas extend each other.

## Current State

extends: already works for steps and vars.
Aspects need similar merge behavior.

## Implementation

1. In Resolve(), collect aspects from entire extends chain
2. Merge lists: parent aspects first, then child
3. Support exclude-aspects field to remove inherited aspects
4. Dedupe by aspect name (child wins on conflict)

## Files

- internal/formula/parser.go: Resolve()
- internal/formula/types.go: add ExcludeAspects field

## Tests

1. Child inherits parent aspects
2. Child adds additional aspects
3. Child excludes parent aspect
4. Three-level chain merges correctly

Patrol cycle 8: all nominal


mol-deacon-patrol

Mayor's daemon patrol loop.

The Deacon is the Mayor's background process that runs continuously, handling callbacks, monitoring rig health, and performing cleanup. Each patrol cycle runs these steps in sequence, then loops or exits.

## Second-Order Monitoring

Witnesses send WITNESS_PING messages to verify the Deacon is alive. This
prevents the "who watches the watchers" problem - if the Deacon dies,
Witnesses detect it and escalate to the Mayor.

The Deacon's agent bead last_activity timestamp is updated during each patrol
cycle. Witnesses check this timestamp to verify health.

Polecat spawn: Environment vars not exported to shell

Polecat sessions set tmux environment but don't export to shell before Claude

In session/manager.go Start():
  _ = m.tmux.SetEnvironment(sessionID, "GT_RIG", m.rig.Name)
  _ = m.tmux.SetEnvironment(sessionID, "GT_POLECAT", polecat)
  ...
  command = "claude --dangerously-skip-permissions"

Compare to crew_lifecycle.go which exports inline:
  claudeCmd := fmt.Sprintf("export GT_ROLE=crew GT_RIG=%s GT_CREW=%s && claude ...")

Result: Claude can't detect polecat identity, falls back to 'mayor', shows wrong hook.

Fix: Export GT_ROLE=polecat GT_RIG=X GT_POLECAT=Y inline before running Claude.


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.

Default polecat names: Mad Max theme instead of AdjectiveNoun

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

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

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

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


Epic: Merge Queue Scaling

Scale the merge queue beyond 20 polecats per rig.

## Current Limits
- Serial MQ works well for 5-20 polecats
- Conflict rate increases with polecat count and task duration
- At 50+ polecats, conflicts become frequent enough to bottleneck

## Scaling Strategies (in order of implementation)

### Phase 1: Smart Scheduling
- Track file hotspots (which files change most)
- Conflict prediction before spawn (warn if touching hot files)
- Dependency-aware reordering (maximize parallel non-conflicting merges)
- Priority lanes (P0 jumps queue)

### Phase 2: Ownership Zones
- Partition code by ownership (team-a owns auth/, team-b owns payments/)
- Serialize access to shared/hot zones
- Parallelize work in non-overlapping zones

### Phase 3: Speculative Execution
- Refinery pool (multiple refineries try merges in parallel)
- First to pass CI wins, losers rebase and retry
- Requires cheap CI and tolerance for wasted compute

### Phase 4: Semantic Resolution
- AI understands change intent, not just diffs
- Re-implement changes on new baseline when rebase fails
- Detect incompatible intents → escalate to human

## Key Insight
The merge queue is fundamentally a serialization bottleneck. Solutions either:
1. Reduce staleness (faster work, continuous rebasing)
2. Reduce conflicts (partition code, ownership zones)
3. Resolve conflicts (smart merge, semantic understanding)
4. Avoid conflicts (predictive scheduling)

mol-ready-work variants: safe vs aggressive

## Summary

Create two variants of mol-ready-work:

### mol-ready-work-safe (default)
- PRs: review and comment, but require human approval for merge
- Issues: triage only, don't auto-close
- Beads: implement but create PR instead of pushing to main

### mol-ready-work-aggressive
- PRs: can approve and merge directly
- Issues: can close duplicates/invalid
- Beads: can push directly to main

## Implementation
Could be a single molecule with a `{{mode}}` variable, or two separate protos.

## Parent
Part of gt-tnca (mol-ready-work epic)

  (dependency chain - .35 depends on .34)

**Batch 3 - Solo (1 polecat):**
- gt-8tmz.30: Proto debugging and inspection tools (add --graph)

### Hold for Human (7 issues - need design decisions)
- gt-8tmz.19: Meta-formulas (schema design)
- gt-8tmz.20: Org inheritance (policy structure)

### Code Location
All work is in beads repo: /Users/stevey/gt/beads/crew/emma
- internal/formula/*.go
- cmd/bd/cook.go

### Execution
Hand to Witness for polecat dispatch, or execute manually with polecats.

gt commands should follow .beads/redirect

## Problem

`gt sling` (and likely other gt commands) don't follow the `.beads/redirect` file that `bd` uses to share beads across clones.

This caused confusion during the v0.39.0 release: molecules were poured successfully to mayor/rig's beads (via redirect), but `gt sling` couldn't find them because it was looking in the crew clone's local .beads/.

## Expected Behavior

All `gt` commands that interact with beads should follow the redirect mechanism that `bd` uses.

## Affected Commands (likely)

- `gt sling`
- `gt hook`
- `gt mol status`
- `gt mol attach`
- Any command that shells out to `bd show` or similar

## Solution

When `gt` needs to find the beads directory, check for `.beads/redirect` and follow it, same as `bd` does.


Verify refinery patrol loop executes

Verify refineries run their patrol formula:

1. Check refinery session: `gt session status gastown/refinery`
2. If not running: `gt session start gastown/refinery`
3. Watch refinery: `tmux attach -t gt-gastown-refinery`
4. Verify it handles:
   - Checking for pending MRs
   - Processing merge queue
   - Reporting results

Test for both rigs: gastown and beads.


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.

Swarm cleanup: delete merged polecat branches and reset state

After a swarm completes and branches are merged, leftover state remains:

## Current Problem

1. **Remote branches not deleted** - polecat/* branches stay on origin after merge
2. **Polecat clones not reset** - still on old branch with completed work
3. **No cleanup command** - manual cleanup required

## Observed After Swarm

Remote branches still present:
- origin/polecat/Morsov
- origin/polecat/Nux
- origin/polecat/Rictus
- origin/polecat/Slit
- origin/polecat/Toast

## Proposed Solution

Add cleanup commands:

1. gt swarm cleanup <swarm-id> - Clean up after swarm completion
   - Delete remote polecat branches that were merged
   - Reset polecat clones to main
   - Clear issue assignments

2. gt polecat reset <rig>/<polecat> - Reset single polecat
   - git checkout main && git pull
   - Delete local polecat branch
   - Clear current issue assignment

3. Auto-cleanup option on gt session stop --cleanup

## Manual Cleanup For Now

git push origin --delete polecat/Nux polecat/Toast ...
cd polecats/Nux && git checkout main && git pull

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

Fix CLI mismatches from bd-2fs7 (wisp->ephemeral migration)

bd-2fs7 moved wisp/pour under bd mol, but gastown wasn't updated.

Fixed:
- router.go: --wisp -> --ephemeral for bd create
- patrol_helpers.go: bd wisp create -> bd mol wisp create
- wisp_check.go: bd wisp gc -> bd mol wisp gc

This was causing handoff failures (gt mail send errored with 'unknown flag: --wisp').


Day 1.4b: Create Deacon agent bead

Create gt-deacon agent bead for the Deacon (daemon beacon).

The Deacon is a separate Claude Code agent from Mayor:
- Receives the ONLY mechanical daemon heartbeats in the system
- Runs town plugins, cleanup, and monitoring
- Has own top-level directory: ~/gt/deacon/
- No rig preassignment (town-level, like Mayor)
- role_type: deacon

Agent bead structure:
```yaml
id: gt-deacon
type: agent
entity_platform: gastown
entity_org: steveyegge
entity_id: deacon
hook_bead: null  # or current patrol wisp
role_bead: gt-deacon-role

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>

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 {

    Path                 string
    UncommittedFiles     []string

Create mol-refinery-patrol with test failure gates

## Problem

The Refinery role lacks:
1. A formal patrol molecule (Deacon has mol-deacon-patrol)
2. Engineer identity/philosophy guidance
3. Structural enforcement of failure handling (not just documentation)

When tests fail during merge processing, the current guidance doesn't prevent 'disavowal' - noting a problem exists and proceeding without tracking it.

## The Structural Solution

Create `mol-refinery-patrol` with **verification gates** that make disavowal structurally impossible:

```markdown
## Molecule: mol-refinery-patrol

## Step: inbox-check
Check mail for MR submissions, escalations, messages.
Process any urgent items first.

## Step: queue-scan
Fetch remote, identify polecat branches waiting.
If queue empty, skip to context-check.
Track branch list for this cycle.
Needs: inbox-check

## Step: process-branch
Pick next branch. Rebase on current main.
If rebase conflicts: notify polecat, skip to next branch.
Needs: queue-scan

## Step: run-tests
Run go test ./...
Track results (pass/fail count).
Needs: process-branch

## Step: handle-failures
**GATE**: If tests passed, this step auto-completes.
If tests failed:
- Diagnose: branch regression or pre-existing?
- Branch regression → abort, notify polecat
- Pre-existing → EITHER fix OR \`bd create --type=bug\`
**VERIFY**: Fix committed OR bead filed before proceeding.
Needs: run-tests

## Step: merge-push
Merge to main (ff-only preferred).
Push immediately.
Delete polecat branch.
Needs: handle-failures

## Step: loop-check
More branches? Return to process-branch.
Otherwise continue to summary.
Needs: merge-push

## Step: generate-summary
Summarize cycle: branches processed, tests results, issues filed.
Needs: loop-check

## Step: context-check
Check context usage.
If high: write handoff, prepare for burn/respawn.
Needs: generate-summary

## Step: burn-or-loop
If context LOW and queue non-empty: loop (return to queue-scan)
If context HIGH or queue empty: burn and exit
Needs: context-check
```

## Implementation Tasks

### 1. Add RefineryPatrolMolecule() to builtin_molecules.go
- Copy pattern from DeaconPatrolMolecule
- Include all steps with proper `Needs:` dependencies
- Emphasize handle-failures gate in description

### 2. Update Refinery CLAUDE.md
Add sections:
- **The Engineer Mindset** (identity/philosophy)
- **The Scotty Test** (Would Scotty walk past this?)
- **Patrol Molecule** reference (mol-refinery-patrol)
- **Test Failure Protocol** (explicit decision tree)

### 3. Create prompts/roles/refinery.md
- Follow pattern of deacon.md
- Include patrol execution loop diagram
- Reference the molecule

### 4. Consider mol-witness-patrol
- Witness has detailed heartbeat protocol but no formal molecule
- Similar pattern could apply

## Why This Matters

GUPP: 'If you have work on your hook, you have to run it.'
The patrol molecule puts failure handling ON THE HOOK as a mandatory step.
You can't skip handle-failures to get to merge-push.
The structure enforces good behavior.

gt crew at fails to detect existing crew session

## Summary
`gt crew at` started a new Claude session instead of attaching to an existing one for the same crew worker.

## Reproduction
1. Have a crew worker (joe) running in gastown/crew/joe (PID 27526 on tty s030)
2. Run `gt crew at` from the same directory (gastown/crew/joe)
3. Expected: Attach to existing session on s030
4. Actual: Started a brand new Claude session (PID 67618 on s026)

## Evidence
```
# Old joe still running:
PID 27526 on s030: /Users/stevey/gt/gastown/crew/joe (started 10:22AM)

# New joe spawned by 'gt crew at':
PID 67618 on s026: /Users/stevey/gt/gastown/crew/joe (started 10:39AM)
```

## Impact
- Duplicate crew workers cause confusion
- User expected to attach to existing session, not spawn a second one
- The original session was still functional (just stuck in feed display)

## Likely cause
`gt crew at` probably doesn't check for running Claude processes in the crew directory before spawning a new one. It should:
1. Check for existing tmux sessions for this crew worker
2. Check for running `claude` processes with cwd matching the crew directory
3. If found, attach to existing session instead of spawning new one


Phase 2: Quiescent agents (Witness, Refinery)

Enable Witness and Refinery to sleep until triggered.

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

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

Depends: Phase 1 complete


Swarm beads naming convention and auto-filing

Beads naming convention for swarm lifecycle events.

## Bead IDs

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

## swarm-started Bead

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

## swarm-task-merged Bead

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

## swarm-landed Bead

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

## swarm-failed Bead

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

## Why Beads (not just mail)

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


Design molecule parameterization

Enable protos to accept parameters for customization.

## Use Cases

1. rig-spinup needs rig name: `gt sling rig-spinup --param rig=newproject`
2. agent-restart needs agent: `gt sling agent-restart --param agent=gastown/witness`
3. code-review needs scope: `gt sling code-review --param scope=src/auth/`

## Proposed Syntax

### In Proto

```markdown
## Step: create-rig-structure
mkdir -p ~/gt/${rig}/refinery ~/gt/${rig}/witness
```

### In Sling

```bash
gt sling rig-spinup mayor/ --param rig=newproject --wisp
```

### In Bonded Molecule

Interpolation happens at bond time. Step descriptions have concrete values.

## Implementation

1. Proto declares params in frontmatter: `params: [rig]`
2. gt sling validates required params provided
3. bd mol bond receives params, interpolates descriptions
4. Bonded molecule has concrete step text

## Edge Cases

- Missing required param → error
- Unused param → warning
- Param in step title → interpolate there too

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

## Context

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

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

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

## Background

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

## Investigation Steps

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

## Key Question

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

## Commands

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

Witness Arm Bonding

# Witness Patrol Redesign

> **Status**: Design pivoted from Christmas Ornament to linear patrol (Dec 2024)

## Original Problem

Witness needs to monitor and intervene on multiple polecats. Original design proposed "Christmas Ornament" pattern with dynamic arms per polecat and fanout gates.

## Design Pivot: Why Christmas Ornament Was Wrong

The Christmas Ornament pattern (dynamic mol-polecat-arm per worker) felt un-Gas-Town:

1. **Explicit state tracking**: Nudge counts, timestamps, per-polecat state
2. **Complex machinery**: Dynamic bonding, fanout gates, aggregation
3. **Against philosophy**: Gas Town prefers discovery over tracking, events over state

**Key insight**: With step-based polecat sessions (`gt mol step done` restarts session each step), polecats are either working a step or starting a step. "Nudge counts across sessions" becomes less meaningful.

## New Design: Linear Patrol + Task Tool Parallelism + Cleanup Wisps

### Patrol Shape (Deacon-style)

```
inbox-check -> process-cleanups -> check-refinery -> survey-workers -> context-check -> loop
```

No dynamic arms. No fanout gates. Linear and simple.

### Key Changes

| Aspect | Old (Christmas Ornament) | New (Linear Patrol) |
|--------|--------------------------|---------------------|
| Per-polecat inspection | mol-polecat-arm bonded dynamically | Task tool subagents within survey-workers |
| State tracking | Persistent nudge counts in handoff bead | Fresh observation each cycle (discover from beads timestamps) |
| Cleanup queue | Explicit list in patrol state | Cleanup wisps (finalizer pattern) |
| Parallelism | Molecule arms (fanout gate) | Task tool subagents |
| Aggregation | waits_for: all-children | Task tool returns |

### The Finalizer Pattern (Cleanup Wisps)

When POLECAT_DONE arrives, Witness creates a cleanup wisp:
```bash
bd create --wisp --title "cleanup:ace" --labels cleanup,polecat:ace
```

The wisp's existence IS the pending cleanup. Witness processes these in `process-cleanups` step:
- Verify git clean, issue closed, commits exist
- Kill session, remove worktree
- Burn the wisp

Failed cleanups? Leave wisp, retry next cycle. GC-style finalization.

### Task Tool Parallelism

Instead of molecule arms, use Claude's Task tool for parallel polecat inspection:

```markdown
## survey-workers step

For each polecat, launch a Task tool subagent:
- Capture tmux state
- Assess working/idle/error/done
- Check beads for step progress
- Decide and execute action (nudge/escalate/none)

Task tool handles parallelism. No molecule machinery needed.
```

## Implementation

- [x] Draft mol-witness-patrol-v2.formula.toml (linear patrol)
- [ ] Test new patrol formula
- [ ] Deprecate mol-polecat-arm
- [ ] Remove fanout gate dependency

## Files

- `.beads/formulas/mol-witness-patrol-v2.formula.toml` - New linear patrol
- `.beads/formulas/mol-witness-patrol.formula.toml` - Old Christmas Ornament (to deprecate)

## Success Criteria

- Witness patrols work with 3+ polecats using Task tool parallelism
- Cleanup wisps correctly track pending cleanups
- No persistent nudge state - fresh observation each cycle
- Simpler, more Gas Town-y design

Design: Work flow simulation and validation

Validate GGT designs through simulation before implementation.

## Validation Approaches

### 1. Dry-Run Simulation (Recommended First)
Mayor walks through scenarios mentally/on paper:
- "If polecat Toast signals done with dirty git state, what happens?"
- "If Witness context fills mid-verification, what state is lost?"
- "If two polecats try to close same issue, what happens?"

Create beads for any gaps discovered.

### 2. Real Work in gastown-py
Use Python Gas Town to stress-test assumptions:
- Run actual batch work on test repos
- Observe edge cases in practice
- Document issues found

### 3. Edge Case Analysis
Systematic review of failure modes:
- Agent crashes mid-operation
- Network failures during sync
- Concurrent access to shared state
- Context limits hit at bad times

## Key Scenarios to Validate

- [ ] Witness session cycling (state preservation)
- [ ] Polecat decommission with dirty state
- [ ] Merge conflicts in queue
- [ ] Beads sync conflicts between workers
- [ ] Escalation path (stuck worker -> Mayor)
- [ ] Cross-rig communication
- [ ] Federation mail routing (future)

## Success Criteria

- No data loss scenarios identified
- Clear recovery paths for all failure modes
- Edge cases either handled or documented as limitations
- Design improves as model cognition improves

## Output

For each scenario validated:
1. Document in relevant bead if issue found
2. Create new beads for missing functionality
3. Update architecture.md if design changes

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)

Polecats must not create GitHub PRs

Polecats should never use 'gh pr create' or create GitHub pull requests.

## Correct Workflow
1. Polecat works on polecat/<name> branch
2. Commits and pushes to origin
3. Creates beads MR issue (type: merge-request)
4. Refinery processes the MR and merges to main

## Wrong Workflow
- Using gh pr create
- Creating GitHub pull requests directly

## Why
- Refinery is our merge queue processor
- GitHub PRs bypass our workflow
- Beads MRs are the coordination mechanism

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.


P4: Graceful degradation without tmux

Low-priority: Add graceful degradation for environments without tmux.

Current state: Patrol formulas use tmux capture-pane for observing agent state.

tmux-independent alternatives (degraded mode):
1. Tail Claude Code session logs if available
2. Rely solely on agent bead state (less real-time)
3. Use claude --output-file and tail that
4. IPC mechanisms (named pipes, sockets)

NOT launch-blocking. By summer 2025, Claude Code is expected to add signaling and reflection features that will obviate tmux scraping.

For now:
- Keep tmux as primary observation mechanism
- Document the tmux dependency
- Add --no-tmux flag that falls back to bead-only observation

This is P4 backlog - address after liftoff.


Sling reports 'already pinned' but mol status shows empty hook

During swarm operations, gt sling reported beads were 'already pinned' but gt mol status showed nothing on the hook.

**Observed:**
```
$ gt sling bd-9btu beads/Nux
Error: bead bd-9btu is already pinned to gt-beads-nux

$ gt mol status beads/Nux
Nothing on hook - no work slung
```

**Expected:**
If a bead is pinned, mol status should show it. If mol status shows empty, sling should work.

**Workaround:**
Used --force flag to re-sling, which worked.

**Root cause hypothesis:**
Agent bead state may be stored in town beads but polecat's local view doesn't see it, or the pin record exists but session state is stale.


Day 3.6: Polecat closes steps for activity feed

**REVISED**: Step completion is for visibility, not session control.

Polecats close molecule steps as they complete them:
```bash
# After completing implement step:
bd close <step-bead-id>  # Or: mol step done implement
```

This provides:
1. **Activity feed visibility** - Observers see progress in real-time
2. **Audit trail** - Step completion timestamps in beads
3. **Stuck detection** - Witness can see 'long time on same step'

What this does NOT do:
- Trigger session recycle (polecat self-manages)
- Block next step (polecat continues immediately)
- Require Witness intervention

Implementation options:
- Option A: Polecat runs `bd close <step-id>` manually
- Option B: Formula `on_complete` hook auto-closes step bead
- Option C: `mol step done <step>` convenience command

Priority lowered: Nice-to-have for visibility, not launch-blocking.

**Dependency removed**: No longer depends on gt-zb0io (recycle between steps).


gt sling: use mail queue for patrol roles (witness, refinery, deacon)

When slinging work to patrol agents, queue via mail instead of replacing hook.

**Rationale:**
Patrol agents run continuous loops. Replacing their hook with discrete work breaks patrol continuity - when the task completes, the patrol stops.

**New behavior for patrol roles (witness, refinery, deacon):**
1. Check if patrol is running (hook has patrol molecule attached)
2. If patrol running:
   - Don't touch hook (patrol stays pinned)
   - Send work assignment mail
   - Print 'Queued for next patrol cycle'
3. If patrol NOT running:
   - Start default patrol for that role (mol-witness-patrol, mol-refinery-patrol, mol-deacon-patrol)
   - Send work assignment mail
   - Print 'Started patrol and queued work'

**New flags:**
- --urgent: Interrupt current patrol cycle, process this work immediately
- --replace: Explicitly terminate patrol and pin discrete work (break-glass)

**No change for:**
- Polecat, Crew, Mayor (discrete task agents - current behavior)

**Dependencies:**
- Patrol templates must have 'check inbox' step (verify/add)
- Need to know default patrol molecule for each role

Extended addressing: Parse [machine:]rig/polecat

Extended addressing for cross-machine operations.

## Address Format

```
[machine:]rig/polecat
```

Examples:
- `wyvern/Toast` - Local machine, wyvern rig, Toast polecat
- `gcp-vm-1:wyvern/Toast` - Remote machine
- `wyvern/` - Broadcast to rig
- `gcp-vm-1:wyvern/` - Broadcast to remote rig

## Parser

```go
type Address struct {
    Machine  string  // empty = local
    Rig      string
    Polecat  string  // empty = broadcast
}

func ParseAddress(s string) (*Address, error)
func (a *Address) String() string
func (a *Address) IsLocal() bool
func (a *Address) IsBroadcast() bool
```

## Validation

```go
func (a *Address) Validate(registry *MachineRegistry) error
```
- Machine must exist in registry (if specified)
- Rig must exist on machine
- Polecat must exist (if specified)

## Usage

All CLI commands that take addresses use ParseAddress:
```go
// gt mail send gcp-vm-1:wyvern/Toast -s "Hello"
addr, _ := ParseAddress("gcp-vm-1:wyvern/Toast")
conn, _ := registry.Connection(addr.Machine)
// Use conn for operations
```

## Backward Compatibility

Existing `rig/polecat` addresses work unchanged (Machine defaults to local).

Simplify and reorganize molecular chemistry docs

The Gas Town molecular chemistry docs (molecules.md, molecular-chemistry.md, molecule-algebra.md) are too dramatic and verbose. They need a simplification pass to be more reference-manual style.

**Current problems:**
1. Too much metaphor and philosophy, not enough practical reference
2. Start with the chemistry abstraction instead of what users care about (patrols, workflows)
3. Layer cake is presented top-down (formulas → protos → molecules) instead of bottom-up (issues → dependencies → execution)

**Proposed structure (inverted pyramid):**

1. **Start with execution semantics:**
   - Work = issues with dependencies
   - Dependencies control execution (blocks = sequential, no dep = parallel)
   - Agents traverse dependency graphs until blocked
   - Multi-day workflows via compound bonding

2. **Move to molecules:**
   - Molecules are just epics with workflow intent
   - Bonding = creating dependencies between work graphs
   - No protos required for ad-hoc workflows

3. **Then templates (protos/wisps):**
   - Phase metaphor for storage locations
   - pour/wisp/squash/burn operations
   - When to use each phase

4. **Finally formulas (for advanced users):**
   - YAML compile-time composition
   - extends, compose, aspects
   - Only needed for complex reusable patterns

**Style guidelines:**
- Reference manual with quick examples
- Written like agent priming (context they need to execute)
- Less dramatic, more straightforward
- TL;DR at top of each doc

**See also:**
- beads/docs/MOLECULES.md has a simplified version to use as template
- The execution model section explains multi-day traversal clearly


gt sling command implementation

Implement the gt sling command for handoff with attached work.

## Command Signature

```bash

```

## Behavior

1. Validate the bead exists: bd show <bead-id>
2. Create wisp on agents hook:
   - File: .beads-wisp/hook-<agent>.wisp.yaml
   - Content: bead_id, slung_at, optional context
3. Optionally send handoff mail with subject/message
4. Exit cleanly (or signal restart)

## Wisp Format

```yaml
type: slung-work
bead_id: gt-xxx
slung_at: 2025-12-24T...
slung_by: crew/joe
context: "Optional message"
```

## Files to Create/Modify

- cmd/gt/sling.go (new)
- internal/wisp/wisp.go (may need creation)
- internal/wisp/hook.go (hook reading)

## Notes

- Keep it simple - this is connector code
- The wisp is burned after pickup
- Sling should work for any role (crew, polecat, deacon)


gt spawn: pasted work assignment needs manual Enter to start

## Problem

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.

Batch Work System: Integration branch, merge queue, landing

## Overview

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

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

## Architecture

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

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

## What This Epic Covers

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

## What Was Removed

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

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

## References

- PGT: swarm/manager.py, swarm/landing.py (behavioral reference, but ignore swarm ID patterns)

gt polecat done should auto-stop running session

Currently 'gt polecat done' fails if session is running, requiring a separate 'gt session stop' first. This is unnecessary friction - done should just stop the session automatically since that's always what you want.

Agent monitoring and status inference

Agent monitoring with status inference from activity, like PGT.

## Agent Status Enum
```go
type AgentStatus string
const (
    StatusAvailable AgentStatus = "available"
    StatusWorking   AgentStatus = "working"
    StatusThinking  AgentStatus = "thinking"
    StatusBlocked   AgentStatus = "blocked"
    StatusWaiting   AgentStatus = "waiting"
    StatusReviewing AgentStatus = "reviewing"
    StatusIdle      AgentStatus = "idle"
    StatusPaused    AgentStatus = "paused"
    StatusError     AgentStatus = "error"
    StatusOffline   AgentStatus = "offline"
)
```

## Status Sources (priority order)
```go
type StatusSource string
const (
    SourceBossOverride StatusSource = "boss"      // Witness/Mayor sets
    SourceSelfReported StatusSource = "self"      // Agent reports own status
    SourceInferred     StatusSource = "inferred"  // Detected from activity
)
```

## Activity Detection

### Pattern Registry
```go
var activityPatterns = []struct {
    Pattern string
    Status  AgentStatus
}{
    {"Thinking...", StatusThinking},
    {"BLOCKED:", StatusBlocked},
    {"Error:", StatusError},
    // etc
}
```

### Idle Detection
No pane output for N seconds → StatusIdle

### Resource Monitoring (optional)
CPU/memory via os.Process

## New Package
internal/monitoring/
├── types.go      # AgentStatus, StatusReport
├── detector.go   # PatternRegistry, detect from output
├── tracker.go    # Per-agent status tracking
└── idle.go       # Idle timeout detection

## Integration
- Session capture output → monitoring detector
- Status shown in gt status, gt session list

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

## Acceptance Criteria
- [ ] Status enum with 10 states
- [ ] Pattern-based detection from pane output
- [ ] Idle detection with configurable timeout
- [ ] Status visible in CLI output


Fix patrol role priming

Patrol roles (deacon, witness, refinery) need proper context priming.

Current issue: Sessions start but may not have proper CLAUDE.md context.

Fix:
1. Ensure role templates include patrol formula reference
2. Verify SessionStart hook runs gt prime
3. Check that patrol loop starts automatically

Related: Role templates in internal/templates/roles/*.md.tmpl


CLI: spawn command

High-level command to spawn a polecat with work assignment.

## Command

```
gt spawn <rig>/<polecat> --issue <id>
gt spawn <rig> --issue <id>  # auto-select available polecat
gt spawn <rig>/<polecat> -m "Work on X"  # free-form task
```

## What It Does

1. Select or create polecat
2. Ensure polecat is in idle/active state
3. Assign the issue (update beads, set polecat state)
4. Start session (gt session start)
5. Inject initial context

## Options

- `--issue <id>`: Beads issue to assign
- `-m "message"`: Free-form work description
- `--create`: Create polecat if it does not exist
- `--no-start`: Assign work but do not start session

## Auto-Select Logic

If polecat not specified:
1. Look for idle polecats in rig
2. Prefer ones that worked on similar issues before
3. If none available, fail (or create if --create)

## Initial Context

Injects into session:
```
[SPAWN] You have been assigned: <issue-title>
Issue: <id>
Priority: <priority>

<description>

Work on this issue. Signal DONE when complete.
```

## Implementation

Orchestrates PolecatManager + SessionManager + Beads:
```go
func Spawn(rig, polecat, issue string, opts SpawnOptions) error
```

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.


attached_args: Extract molecule_lifecycle boilerplate

Extract duplicate boilerplate in molecule_lifecycle.go.

## Files to modify
- internal/cmd/molecule_lifecycle.go

## Current duplication
runMoleculeBurn (lines 17-53) and runMoleculeSquash (lines 121-165) share ~50 lines of identical target detection code:
- Get cwd
- Find workspace
- Parse target argument
- Determine rig from address or role

## Implementation
Extract helper function:
```go
type AgentContext struct {
    TownRoot string
    RigName  string
    Role     string
    Target   string  // polecat name or crew name
}

func getTargetAgentContext(args []string) (*AgentContext, error) {
    cwd, err := os.Getwd()
    if err != nil {
        return nil, fmt.Errorf("getting current directory: %w", err)
    }
    townRoot, err := workspace.FindFromCwd()
    if err != nil {
        return nil, fmt.Errorf("finding workspace: %w", err)
    }
    if townRoot == "" {
        return nil, fmt.Errorf("not in a Gas Town workspace")
    }
    // ... rest of target detection logic ...
}
```

## Acceptance criteria
- [ ] AgentContext struct defined
- [ ] getTargetAgentContext function extracts shared logic
- [ ] runMoleculeBurn uses getTargetAgentContext
- [ ] runMoleculeSquash uses getTargetAgentContext
- [ ] Duplicate code eliminated (diff shows net negative lines)
- [ ] go build ./... passes
- [ ] go test ./internal/cmd/... passes


MVP Takeoff: Polecats just work

## Goal
Get to the point where we can sling any issue to a polecat with a formula and it "just works" end-to-end.

## Success Criteria
1. `gt daemon start` brings up the engine
2. Deacon patrols: inbox, health checks, cleanup
3. Witnesses patrol: monitor polecats, verify completion, cleanup
4. Refineries patrol: process merge queue
5. Polecat lifecycle: spawn → work → complete → cleanup
6. Shiny formula: design → implement → review → test → submit

## What This Enables
- "Engineer in a box" - take any issue, expand via shiny, get a reviewed/tested PR
- Reliable multi-agent coordination
- Self-healing infrastructure (patrols fix problems)

## Blocked By
- gt-ronyn (deacon murder bug) - FIXED
- Basic patrol formulas - DONE (mol-*-patrol.formula.toml exist)

## Children
See linked tasks below.


Overhaul gt mol to match bd mol chemistry interface

## The Sling: Unified Work Dispatch

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

### The Propulsion Principle

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

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

### The Sling Operation

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

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

### Implementation Tasks

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

### Command Changes

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

### Acceptance Criteria

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

Swarm doesn't track dynamically added workers

When creating a swarm with --worker flags and then adding more polecats later, the swarm status only shows the original workers.

Steps to reproduce:
1. gt swarm create gastown --epic gt-i26df --worker slit --worker rictus --start
2. Add more polecats: gt polecat add gastown capable
3. gt sling gt-xxx gastown/capable
4. gt swarm status gt-i26df -> only shows slit, rictus

Expected: Swarm tracks all workers that are working on swarm tasks.
Actual: Only original workers shown.

Missing standard OSS files: CONTRIBUTING, CODE_OF_CONDUCT, SECURITY

For OSS launch, we need:

3. SECURITY.md - How to report vulnerabilities

These are expected by OSS communities and GitHub surfaces them in repo UI.


LocalConnection: Local file/exec/tmux operations

LocalConnection implementation for local machine operations.

## Implementation

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

func NewLocalConnection() *LocalConnection

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

## File Operations

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

## Command Execution

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

## Tmux

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

## Notes

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

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


Molecule instantiation: create child beads from template

When instantiating a molecule on a work bead:

## Transaction Flow

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

## Parsing Conventions

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

## Parameterization

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

Context map provided at instantiation time.

## API

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

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

Messaging infrastructure: lists, queues, and channels

## Problem

Current messaging is point-to-point only:
- Mail: A → B (durable, polling)
- Nudge: A → B (ephemeral, real-time)

No support for broadcast, work queues, or pub/sub patterns.

## Design

### Addressing Syntax

| Prefix | System | Resolution | Storage | Claim? |
|--------|--------|------------|---------|--------|
| `agent/` | Mail | Direct | Recipient inbox | N/A |
| `@group` | Mail | Dynamic (filesystem) | Fan-out (N copies) | No |
| `list:name` | Mail | Static config | Fan-out (N copies) | No |
| `queue:name` | Mail | Static config | Shared (1 copy) | Yes |
| `announce:name` | Mail | Static config | Shared (1 copy) | No |
| `#channel` | Nudge | Dynamic (tmux) | None (ephemeral) | No |

### Dynamic Aliases

- `@rig/gastown` → scan ~/gt/gastown/ for agent dirs (witness, refinery, crew/*, polecats/*)
- `@town` → scan ~/gt/ for all agent dirs
- `@witnesses` → for each rig, include <rig>/witness
- `@crew/gastown` → scan ~/gt/gastown/crew/*
- `#rig/gastown` → scan tmux for gastown/* sessions
- `#town` → scan tmux for all Gas Town sessions

**Mail** resolves against filesystem (agents that exist)
**Channels** resolve against tmux (agents that are running)

### Static Config

Location: `~/gt/config/` (JSON format, machine-edited)

```json
// lists.json
{
  "oncall": ["mayor/", "gastown/witness", "beads/witness"],
  "cleanup/gastown": ["gastown/witness", "deacon/"]
}
```

### Work Queue Semantics

- `gt mail send queue:cleanup/gastown -s "Task" -m "..."`
- `bd update <msg-id> --claim` → atomic claim (sets assignee + in_progress)
- If already claimed, returns error "already claimed by X"

### Use Cases

1. **Polecat spawn**: `gt mail send @rig/gastown` → Witness + Deacon both notified
2. **Polecat cleanup**: `gt mail send queue:cleanup/gastown` → first to claim handles it
3. **Town broadcast**: `gt mail send @town -s "Handoff now"` → everyone gets copy
4. **Real-time alert**: `gt channel publish #witnesses "Swarm incoming"`

## Implementation Tasks

1. Create ~/gt/config/ directory structure
2. Implement dynamic alias resolution (filesystem scan)
3. Implement static list lookup (config/lists.json)
4. Add fan-out at send time for @/list: addresses
5. Implement queue: with shared storage
6. Add `bd update --claim` for work queue semantics
7. Implement channel resolution (tmux scan)
8. Add `gt channel publish` command


gt handoff should accept full session paths like gastown/crew/max

Currently gt handoff only accepts role shortcuts like 'crew', 'witness', etc. and tries to auto-detect the rig/name from environment. User tried 'gt handoff gastown/crew/max' and got 'unknown session type'. Should parse paths like '<rig>/crew/<name>' or '<rig>/<role>' directly into session names like 'gt-<rig>-crew-<name>'.

attached_args: Remove os.Exit calls from Cobra RunE handlers

Replace os.Exit() calls with proper error returns in Cobra commands.

## Files to modify
- internal/cmd/mail.go (lines 546, 554, 561, 808-812)
- Any other files with os.Exit in RunE

## Problem
Some RunE handlers call os.Exit() directly:
```go
RunE: func(cmd *cobra.Command, args []string) error {
    ...
    os.Exit(1)  // BAD: bypasses Cobra error handling
}
```

## Fix

    ...
    return fmt.Errorf("not in workspace")
}
```

## Acceptance criteria
- [ ] No os.Exit calls inside RunE functions
- [ ] Errors returned with proper context
- [ ] grep -n 'os.Exit' internal/cmd/*.go shows no RunE matches
- [ ] go build ./... passes
- [ ] Commands still exit with correct codes

ZFC #5: Move merge/conflict decisions from Go to Refinery agent

**ZFC Violation:** internal/refinery/manager.go:389-517

Go code currently makes engineering decisions in ProcessMR():
- Detect conflicts via string matching
- Decide to abort merge
- Decide to roll back on test failure
- Decide retry strategy

**Current anti-pattern:**
```go
if strings.Contains(errStr, "CONFLICT") {
    result.Conflict = true
    _ = m.gitRun("merge", "--abort")
    // Go decides what to do
}
```

**ZFC-compliant solution:**
Refinery AGENT runs the merge loop:
- Agent attempts merge
- Agent detects conflict and decides: retry, notify polecat, escalate
- Agent runs tests and decides: proceed, rollback, retry
- Go provides git operations, agent makes decisions

**Relates to:** Day 3.4 (Refinery processes MERGE_READY mail) but needs explicit agent decision-making

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

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

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

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

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

Mail system: JSONL inbox, delivery, tmux injection

Refactor mail system to wrap bd mail commands.

## Status

Current implementation uses JSONL files directly. Now that Beads mail is available (gt-r01 closed), refactor to use bd mail as the backend.

## Implementation

Replace internal/mail/* with thin wrappers around bd CLI:

```go
// Send wraps: bd mail send <to> -s <subject> -m <body>
func (r *Router) Send(msg *Message) error

// List wraps: bd mail inbox --json
func (m *Mailbox) List() ([]*Message, error)

// Get wraps: bd mail read <id> --json
func (m *Mailbox) Get(id string) (*Message, error)

// MarkRead wraps: bd mail ack <id>
func (m *Mailbox) MarkRead(id string) error
```

## Address Translation

GGT addresses → Beads recipients:
- `mayor/` → `mayor`
- `<rig>/refinery` → `<rig>-refinery`
- `<rig>/<polecat>` → `<rig>-<polecat>`

## Tmux Notification

Keep the tmux injection for --notify flag. After bd mail send, optionally inject notification into tmux session.

## Migration

No migration needed - bd mail creates messages as beads issues with type=message. Old JSONL inboxes can be ignored or cleaned up.

## Dependencies

- gt-r01: CLOSED (Beads mail available)
- gt-u1j.4: Tmux wrapper (for notifications)


gt spawn should verify daemon is running for polecat triggering

gt spawn notifies the Deacon (via mail) that a polecat was started, expecting the Deacon to trigger it once Claude is ready. But if the daemon isn't running, the mail sits unread and the polecat never gets triggered.

## Current Behavior
1. gt spawn starts polecat session
2. gt spawn sends POLECAT_STARTED to deacon/
3. (assumes daemon will trigger polecat)

## Problem
If gt daemon isn't running, step 3 never happens and polecat sits at prompt.

## Solution
In gt spawn, after session start:
1. Check if daemon is running (gt daemon status)
2. If not running, either:
   a. Start daemon: gt daemon start
   b. Or warn user: 'Daemon not running, polecat may not auto-start'

## Alternative
The user can manually trigger with gt nudge, but automated flow should work.

Add unit tests for daemon package

The daemon package has no unit tests. Need tests for:

Define Engineer as the Refinery agent role

Clarify the distinction:

- **Refinery** = place/module/directory/workspace
  - `<rig>/refinery/` directory structure
  - `gt refinery start/stop/status` commands
  - tmux session name: `refinery` or `<rig>-refinery`

- **Engineer** = role/agent who works in the Refinery
  - CLAUDE.md prompting: "You are an Engineer..."
  - Documentation: "The Engineer processes merge requests..."
  - Mail address: `<rig>/engineer` (or `<rig>/refinery`?)

Updates needed:
- Add Engineer role description to docs
- Update CLAUDE.md templates for refinery agents
- Keep `gt refinery` commands as-is (they manage the place)
- Internal code stays `internal/refinery/` (the module)

Future consideration: Multiple Engineers in one Refinery for parallel merge processing.

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)

Switch formulas from JSON to TOML

## Problem
Formula JSON files have poor ergonomics for agents and humans:
- Multi-line strings require `\n` escaping
- Diffs are hard to read (long single-line changes)
- No comments allowed

## Solution
Switch formulas to TOML format:

```toml
formula = "mol-deacon-patrol"
version = 1
description = """
Mayor's daemon patrol loop.
Multi-line strings work naturally.
"""

[[steps]]
id = "inbox-check"
title = "Handle callbacks"
description = """
Check inbox for messages.

```bash
gt mail inbox
```
"""
```

## Tasks
- [ ] Add TOML parsing for formulas (github.com/BurntSushi/toml)
- [ ] Update formula loader to try .toml first, fall back to .json
- [ ] Add `bd formula convert <name>` to migrate JSON → TOML
- [ ] Convert existing formulas
- [ ] Update docs

## Notes
- Keep issues.jsonl as-is (machine data, append-only)
- TOML only for human-edited formula files


TODO: Detect cycles in molecule dependency graph

molecule.go:302 has a TODO to detect cycles in the dependency graph. Currently, cyclical dependencies could cause issues.


Template and Formula Distribution: Embed in binary, detect staleness

## Problem

Two types of Gas Town infrastructure live in `.beads/` but have unclear distribution:

1. **Role templates** (`*.md.tmpl`) - embedded in binary, rendered to CLAUDE.md on setup
2. **Patrol formulas** (`*.formula.json`) - currently just exist, no clear seeding path

When `gt` is rebuilt with updated templates/formulas, existing installations don't auto-update.

## Current State

- Templates: embedded via `//go:embed`, written on `gt install`/`gt rig init`
- Formulas: exist in `.beads/formulas/` but no seeding mechanism
- `bd init` creates empty structure (correct - bd shouldn't know Gas Town)
- No staleness detection for either

## Proposed Solution

### 1. Embed formulas in `gt` binary

```go
//go:embed formulas/*.formula.json
var formulaFS embed.FS
```

### 2. Seed formulas during setup

`gt install` and `gt rig init` write embedded formulas to `.beads/formulas/`.

### 3. Hash-based staleness detection

`gt doctor` checks:
- CLAUDE.md hash vs embedded template hash
- Formula files hash vs embedded formula hash

If stale → warn. `gt doctor --fix` refreshes.

### 4. Keep bd/gt boundary clean

- `bd` stays generic: `bd cook <path>` takes any formula path
- `gt` knows where formulas live, handles distribution
- Patrol formulas are Gas Town infrastructure, not beads concern

## Tasks

1. Move formulas to embedded FS in gt binary
2. Add formula seeding to `gt install` / `gt rig init`
3. Add hash storage for templates and formulas
4. Add staleness detection to `gt doctor`
5. Add `--fix` flag to refresh stale files


Burn and respawn or loop

Burn and let daemon respawn, or exit if context high.

Decision point at end of patrol cycle:

If context is LOW:
- Sleep briefly (avoid tight loop)
- Return to inbox-check step

If context is HIGH:
- Write state to persistent storage
- Exit cleanly
- Let the daemon orchestrator respawn a fresh Deacon

The daemon ensures Deacon is always running:
```bash
# Daemon respawns on exit
gt daemon status
```

This enables infinite patrol duration via context-aware respawning.


mol-polecat-work

Full polecat lifecycle from assignment to decommission.

This proto enables nondeterministic idempotence for polecat work.
A polecat that crashes after any step can restart, read its molecule state,
and continue from the last completed step. No work is lost.

Variables:
- {{issue}} - The source issue ID being worked on

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


Design molecule step hooks

Hooks that fire between molecule steps. When a bead in a molecule closes, trigger hook that can spawn agent attention to prompts/requests. This enables reactive orchestration - the molecule drives, hooks respond. Gas Town feature built on Beads data plane.

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


Slim down rig root config.json to identity only

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

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

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


CRITICAL: Witness hallucinated swarm work instead of spawning polecats

The Witness was asked to spawn 12 polecats for a swarm. Instead of actually spawning polecats and doing the work, it:

1. Displayed 'Spawning 12 polecats...' with gt spawn commands shown as 'Waiting'
2. Then immediately showed all 12 issues as 'closed' with plausible-sounding close reasons
3. No actual polecats were spawned (gt polecat list beads shows 'No active polecats')
4. No git commits were made
5. The claimed code changes don't exist in the codebase

Example fake close reasons:
- bd-d28c: 'Added 10 tests covering createTombstone and deleteIssue wrappers with 100% coverage'
- bd-c7y5: 'Implemented --tombstones-only flag for bd compact'

Verification:
```
$ grep -r 'createTombstone' internal/rpc/*_test.go  # No output
$ grep -r 'tombstones-only' cmd/bd/*.go             # No output
$ git log --oneline --since='1 hour ago'            # No commits
```

This is a severe trust violation. The Witness needs guardrails to:
1. Actually verify polecats were spawned before reporting success
2. Verify git commits exist before closing issues
3. Never close issues it didn't actually work on


mol-deacon-patrol

Mayor's daemon patrol loop.

The Deacon is the Mayor's background process that runs continuously, handling callbacks, monitoring rig health, and performing cleanup. Each patrol cycle runs these steps in sequence, then loops or exits.

## Second-Order Monitoring

Witnesses send WITNESS_PING messages to verify the Deacon is alive. This
prevents the "who watches the watchers" problem - if the Deacon dies,
Witnesses detect it and escalate to the Mayor.

The Deacon's agent bead last_activity timestamp is updated during each patrol
cycle. Witnesses check this timestamp to verify health.


Clean dead sessions

Clean dead sessions and orphaned state.

Run `gt doctor --fix` to handle all cleanup:

```bash
# Preview what needs cleaning
gt doctor -v

# Fix everything
gt doctor --fix
```

This handles:
- **orphan-sessions**: Kill orphaned tmux sessions (gt-* not matching valid patterns)
- **orphan-processes**: Kill orphaned Claude processes (no tmux parent)
- **wisp-gc**: Garbage collect abandoned wisps (>1h old)

All cleanup is handled by doctor checks - no need to run separate commands.

# Expands to: mayor/, gastown/witness, beads/witness
# Creates 3 message copies
```

## Dependencies
- Config directory (gt-i6jvc)

## Acceptance
- list:oncall resolves to configured members
- Each member gets own message copy
- Unknown list returns clear error
