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.

This molecule uses dynamic bonding to spawn mol-polecat-arm for each worker,
enabling parallel inspection with a fanout gate for aggregation.

Patrol 10: Quick cycle, 50% to handoff


Clean up duplicate patrol protos (gt-qflq, gt-iep9)

There are duplicate protos for patrol molecules:

## Duplicates

| Old Proto | New Proto | Name |
|-----------|-----------|------|
| gt-qflq | mol-witness-patrol | mol-witness-patrol |
| gt-iep9 | mol-deacon-patrol | mol-deacon-patrol |

The old gt-* prefix protos were created before the formula cooking system.
The new mol-* prefix protos were created by `bd cook`.

## Action

1. Close or delete the old gt-* protos
2. Update any references to use the new mol-* protos
3. Verify `bd mol list` shows clean output

## Root Cause

The bd cook command uses the formula name as the proto ID (mol-*),
not the project prefix (gt-*). This is probably correct behavior,
but means we have legacy protos to clean up.

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).


Design Deacon molecule health-check step

**Context:** After removing Go heuristics, Deacon molecule needs the logic.

**New molecule step: health-scan**

Claude executes:
1. Check Witness heartbeat: gt witness status <rig>
2. Check Refinery heartbeat: gt refinery status <rig>
3. For each, assess: responsive? stuck? needs restart?
4. If unresponsive for N cycles, send escalation mail

**Key difference from Go approach:**
- Claude makes the judgment call, not hardcoded thresholds
- Claude can read context (what was the agent working on?)
- Claude can ask questions or check additional signals
- Thresholds come from molecule config, not Go constants

**Deliverables:**
- Update mol-deacon-patrol health-scan step
- Add configurable thresholds as molecule variables
- Test with simulated stuck agents


Merge fix/spawn-beads-path branch to main

Branch has gt nudge command; main has notification deduplication. Both valuable.

Key insight: Only ~10 commits diverged each way in mayor/rig.
- Branch: 9509afa feat(nudge): Add gt nudge command (MISSING from main)
- Main: d2fccd5 slot-based notification deduplication (KEEP)

Merge plan:
1. git merge fix/spawn-beads-path --no-ff
2. Keep nudge.go from branch
3. Keep notification.go from main
4. Merge tmux.go (both NudgeSession AND SendKeysReplace)
5. go build && go test
6. Deploy to ~/.local/bin/gt


ensure-gastown-refinery

Start the gastown rig Refinery.

## Action
```bash
gt refinery start gastown
```

## Verify
1. Session exists: `tmux has-session -t gastown-refinery 2>/dev/null`
2. Not stalled: `gt peek gastown/refinery` does NOT show "> Try" prompt
3. Queue processing: Refinery can receive merge requests

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

## OnFail
Log error. Completed polecat work will queue until Refinery recovers.

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


Remove spawn - use pour/wisp only (see bd-8y9t)

Remove bd mol spawn entirely from vocabulary.

Replace all references with:
- bd pour <proto> - Create persistent mol (liquid)
- bd wisp <proto> - Create ephemeral wisp (vapor)

'spawn' doesn't fit the chemistry metaphor. Two phase transitions (pour/wisp) are clearer than one command with flags.

See bd-XXX for Beads-side removal.

- Each agent shows their MOST RECENT activity inline
- At a glance: who is doing what RIGHT NOW
- Collapsible sections

**Bottom panel: Event Stream (chronological feed)**
- Full scrollable history of events
- Most recent at top
- More detail than the tree view
- This is what you scroll through

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.
```


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)

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

## Problem

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

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

## Evidence

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

## Impact

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

## Fix

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

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

Polecat Arm (arm-toast)

Single polecat inspection and action cycle.

This molecule is bonded dynamically by mol-witness-patrol's survey-workers step.
Each polecat being monitored gets one arm that runs in parallel with other arms.

## Variables

| Variable | Required | Description |
|----------|----------|-------------|
| polecat_name | Yes | Name of the polecat to inspect |
| rig | Yes | Rig containing the polecat |

## Step: capture
Capture recent tmux output for toast.

```bash
tmux capture-pane -t gt-gastown-toast -p | tail -50
```

Record:
- Last activity timestamp (when was last tool call?)
- Visible errors or stack traces
- Completion indicators ("Done", "Finished", etc.)

## Step: assess
Categorize polecat state based on captured output.

States:
- **working**: Recent tool calls, active processing
- **idle**: At prompt, no recent activity
- **error**: Showing errors or stack traces
- **requesting_shutdown**: Sent LIFECYCLE/Shutdown mail
- **done**: Showing completion indicators

Calculate: minutes since last activity.
Needs: capture

## Step: load-history
Read nudge history for toast from patrol state.

```
nudge_count = state.nudges[toast].count
last_nudge_time = state.nudges[toast].timestamp
```

This data was loaded by the parent patrol's load-state step and passed
to the arm via the bonding context.
Needs: assess

## Step: decide
Apply the nudge matrix to determine action for toast.

| State | Idle Time | Nudge Count | Action |
|-------|-----------|-------------|--------|
| working | any | any | none |
| idle | <10min | any | none |
| idle | 10-15min | 0 | nudge-1 (gentle) |
| idle | 15-20min | 1 | nudge-2 (direct) |
| idle | 20+min | 2 | nudge-3 (final) |
| idle | any | 3 | escalate |
| error | any | any | assess-severity |
| requesting_shutdown | any | any | pre-kill-verify |
| done | any | any | pre-kill-verify |

Nudge text:
1. "How's progress? Need any help?"
2. "Please wrap up soon. What's blocking you?"
3. "Final check. Will escalate in 5 min if no response."

Record decision and rationale.
Needs: load-history

## Step: execute
Take the decided action for toast.

**nudge-N**:
```bash
tmux send-keys -t gt-gastown-toast "{{nudge_text}}" Enter
```

**pre-kill-verify**:
```bash
cd polecats/toast
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred
```
If clean: kill session, remove worktree, delete branch
If dirty: record failure, retry next cycle

**escalate**:
```bash
gt mail send mayor/ -s "Escalation: toast stuck" -m "..."
```

**none**: No action needed.

Record: action taken, result, updated nudge count.
Needs: decide

## Output

The arm completes with:
- action_taken: none | nudge-1 | nudge-2 | nudge-3 | killed | escalated
- result: success | failed | pending
- updated_state: New nudge count and timestamp for toast

This data feeds back to the parent patrol's aggregate step.

Beads as Universal Data Plane

## Vision

Beads is the data plane for all Gas Town operations. Everything flows through beads:
- Work items (issues, tasks, epics)
- Mail (messages between agents)
- Merge requests (queue entries)
- Workflows (composable execution patterns)
- Resources (leases, locks, quotas)
- Schedules (timed activities)

## New Bead Categories

### Molecules (Composable Workflows)
Crystallized workflow patterns that can be attached to work items.

### Timed Beads (Scheduled Work)
Beads that wake up periodically via daemon.

### Pinned Beads (Ongoing Concerns)
Beads representing persistent concerns, not discrete tasks.

### Resource Beads (Leases/Locks)
Beads representing reserved resources.

## v1 Priority

- **P0**: Molecules (enables engineer-in-box)
- **P2**: Timed, Pinned, Resource beads (post-v1)

ZFC #10: Polecat reports cleanup status instead of Go checking git

**ZFC Violation:** internal/polecat/manager.go:192-215

Go examines git state to decide if polecat removal is safe:
```go
status, err := polecatGit.CheckUncommittedWork()
if status.StashCount > 0 || status.UnpushedCommits > 0 {
    return &UncommittedWorkError{...}
}
```

**ZFC-compliant solution:**
Polecat reports its own cleanup status via agent bead:
- state: stopped
- cleanup_status: clean | has_uncommitted | has_stash | has_unpushed
- Witness reads cleanup_status before calling nuke
- Polecat is authority on whether it's safe to remove

Epic: Async Gates for Agent Coordination

## Summary

Agents need an async primitive for waiting on external events (CI completion,
API responses, human approval). Currently they either poll wastefully or cant
resume after handoff.

## Design: Deacon-Managed Gates

### Core Concepts

**Gate** = wisp issue that blocks until external condition is met
- Type: `gate`
- Phase: wisp (never synced, ephemeral)
- Assignee: `deacon/` (Deacon monitors it)
- Fields: `await_type`, `await_id`, `timeout`, `waiters[]`

**Await Types:**
- `gh:run:<id>` - GitHub Actions run completion
- `gh:pr:<id>` - PR merged/closed
- `timer:<duration>` - Simple delay (e.g., "5m", "1h")
- `human:<prompt>` - Human approval required
- `mail:<pattern>` - Wait for mail matching pattern

### Commands

```bash
bd gate create --await <type>:<id> --timeout <duration> --notify <addr>
bd gate show <id>
bd gate list
bd gate close <id> --reason "completed"
bd gate wait <id> --notify <addr>
```

## Children (suggested breakdown)

1. Add `gate` issue type to beads
2. Add gate fields: await_type, await_id, timeout, waiters
3. Implement `bd gate create/show/list/close/wait` commands
4. Add gate checking to Deacon patrol loop
5. Implement await type handlers (gh:run, gh:pr, timer, human, mail)
6. Add gate timeout tracking and notification
7. Integration test: agent waits for CI via gate

## Open Questions

- Should gates live in wisp storage or main storage with wisp flag?
- Do we need a gate catalog (like molecule catalog)?
- Should `waits-for` dep type work with gates?


Implement gt mq CLI commands

Add gt mq subcommands as sugar over bd:

- gt mq submit: Create MR for current branch
- gt mq list: Show open merge requests
- gt mq next: Show next MR ready to process
- gt mq process: Engineer processes the queue
- gt mq reorder <id> --after <x>: Change ordering via deps
- gt mq status <id>: Show MR details

All commands should work with the Beads data plane.


Load context

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

Read the assigned issue (gt-8tmz.34) and understand the requirements.
Identify any blockers or missing information.

Runtime dynamic expansion (for-each)

Implement runtime expansion for discovered work (the for-each construct).

## Syntax

    step: survey-workers
    on-complete:
      for-each: output.polecats
      bond: mol-polecat-arm
      vars:
        polecat_name: "{item.name}"
        rig: "{item.rig}"
      parallel: true  # or sequential: true

## Design Context (from gt-8tmz.4 review)

This is **control flow**, not just expansion. It affects execution order:
- for-each with parallel: true = concurrent child execution
- for-each with sequential: true = ordered child execution

Key patrol patterns that require this:

| Pattern | Use Case |
|---------|----------|
| Witness survey-workers | For each polecat, bond an arm (parallel) |
| Refinery process-branch | For each branch in queue, run merge pipeline (sequential) |
| Deacon plugin-run | For each plugin where gate open, execute |

## Relationship to gt-8tmz.4

gt-8tmz.4 implements loop, gate, branch (static control flow).
This issue implements for-each (dynamic control flow over runtime-discovered collections).

Together they cover the full control flow needs for patrol formulas.

## Implementation Notes

- Bonds N instances based on step output
- Christmas Ornament pattern: fanout from single step to N parallel children
- Pairs with waits-for gate (gt-8tmz.38) for aggregation
- Collection must be iterable (array in step output)

142 instances of error suppression with _ = pattern

Code has 142 instances of '_ = ' error suppression in non-test code.
Examples:
- internal/polecat/manager.go: _ = pool.Load() - ignores state loading
- internal/daemon/notification.go: _ = os.WriteFile() - ignores file write
- internal/mail/router.go: _ = r.notifyRecipient() - notification ignored

These create silent failures and hard-to-debug issues.

Options:
1. Document intentional suppressions with comments
2. Handle errors properly where appropriate
3. At minimum, log suppressed errors at debug level

Day 3.4: Refinery processes MERGE_READY mail

Refinery patrol handles merge requests:
1. Check inbox for MERGE_READY messages
2. For each, verify branch exists
3. Run merge checks (tests, lint)
4. If passing, merge to main
5. Send MERGED signal back

Engineer main loop: poll for ready merge-requests

Implement the Engineer's main processing loop.

Loop structure:
1. Query: bd ready --type=merge-request
2. If empty: sleep(poll_interval), continue
3. Select highest priority, oldest MR
4. Claim: bd update <id> --status=in_progress
5. Process (delegate to other subtasks)
6. Repeat

Configuration:
- poll_interval: from rig config (default 30s)
- max_concurrent: from rig config (default 1)

The loop should be interruptible and handle graceful shutdown.

gt mail send to self: Auto-detect from cwd for handoff mail

Deacon keepalive: quiet daemon during rounds

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

## Problem

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

## Solution

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

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

## Files

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

## Deacon Behavior

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

## Daemon Changes

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

## Worst Case

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

## Configuration

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


Add org formula examples and tests

Create example organizational formula hierarchy and tests.

## Examples

Create in .beads/formulas/:
- acme-base.formula.yaml: Company-wide (security-audit aspect)
- acme-frontend.formula.yaml: extends acme-base, adds accessibility-audit
- acme-backend.formula.yaml: extends acme-base, adds sql-injection-scan

## Tests

1. Three-level inheritance resolves correctly
2. Aspect merge order is correct
3. exclude-aspects removes parent aspect
4. Cooking org formula produces expected steps
5. Error on missing parent formula

Patrol cycle 6: routine


Bug: MRs appearing in bd ready output

merge-request beads are showing up in `bd ready` output alongside actual work items.

## Problem
`bd ready` is meant to show work available for polecats to claim. MRs are internal workflow items processed by the Refinery, not polecat work.

## Example
```
| P1 | merge-request | bd-3zzh | Merge: bd-tvu3 |
| P1 | merge-request | bd-fcl1 | Merge: bd-au0.5 |
```

## Possible Fixes
1. **Filter by type** - `bd ready` excludes type=merge-request, type=gate, type=molecule
2. **Set assignee on submit** - MR assigned to refinery/ when created, so not 'unassigned'
3. **Set status=in_progress** - MR starts in_progress since it's queued for processing

## Related
- gate beads also showing (bd-hyp6, bd-wu62) - same issue


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'.

Silent error handling with _ = err patterns

Multiple locations intentionally ignore errors with comments like 'Ignore errors'. While some are valid (best-effort operations), others should be audited:

- witness/manager.go:542 - Ignores cmd.Run() error
- refinery/manager.go:411, 438, 509 - Ignores loadState and git pull errors
- swarm/manager.go:47 - Ignores getGitHead error
- polecat/manager.go:69, 284 - Ignores pool.Load and DeleteBranch errors
- swarm/integration.go:101, 137 - Ignores git pull and push errors

Each should be evaluated: log it, handle it, or confirm ignoring is intentional.

Phase 1.2: Daemon attachment detection

Daemon polls Deacon's pinned bead to detect naked state.

## Implementation

- Every heartbeat cycle: bd show <pinned> --json
- Parse attached_molecule field
- If null/empty: Deacon is naked

## Actions on Naked
- Spawn mol-deacon-patrol
- Attach to Deacon's pinned
- Nudge Deacon to start

## Failsafes
- Keepalive file monitoring
- Stale detection (>10min no progress)
- Force nudge on stale

Depends: gt-rana.1


Crew directory structure and config

Add crew/ directory support to rig structure. Include:
- crew/ as peer to polecats/, refinery/, witness/
- Crew worker subdirectories with full git clones
- Optional BEADS_DIR configuration for beads integration
- Crew state tracking (separate from polecat state)


Polecat Arm (arm-toast)

Single polecat inspection and action cycle.

This molecule is bonded dynamically by mol-witness-patrol's survey-workers step.
Each polecat being monitored gets one arm that runs in parallel with other arms.

## Variables

| Variable | Required | Description |
|----------|----------|-------------|
| polecat_name | Yes | Name of the polecat to inspect |
| rig | Yes | Rig containing the polecat |

## Step: capture
Capture recent tmux output for toast.

```bash
tmux capture-pane -t gt-gastown-toast -p | tail -50
```

Record:
- Last activity timestamp (when was last tool call?)
- Visible errors or stack traces
- Completion indicators ("Done", "Finished", etc.)

## Step: assess
Categorize polecat state based on captured output.

States:
- **working**: Recent tool calls, active processing
- **idle**: At prompt, no recent activity
- **error**: Showing errors or stack traces
- **requesting_shutdown**: Sent LIFECYCLE/Shutdown mail
- **done**: Showing completion indicators

Calculate: minutes since last activity.
Needs: capture

## Step: load-history
Read nudge history for toast from patrol state.

```
nudge_count = state.nudges[toast].count
last_nudge_time = state.nudges[toast].timestamp
```

This data was loaded by the parent patrol's load-state step and passed
to the arm via the bonding context.
Needs: assess

## Step: decide
Apply the nudge matrix to determine action for toast.

| State | Idle Time | Nudge Count | Action |
|-------|-----------|-------------|--------|
| working | any | any | none |
| idle | <10min | any | none |
| idle | 10-15min | 0 | nudge-1 (gentle) |
| idle | 15-20min | 1 | nudge-2 (direct) |
| idle | 20+min | 2 | nudge-3 (final) |
| idle | any | 3 | escalate |
| error | any | any | assess-severity |
| requesting_shutdown | any | any | pre-kill-verify |
| done | any | any | pre-kill-verify |

Nudge text:
1. "How's progress? Need any help?"
2. "Please wrap up soon. What's blocking you?"
3. "Final check. Will escalate in 5 min if no response."

Record decision and rationale.
Needs: load-history

## Step: execute
Take the decided action for toast.

**nudge-N**:
```bash
tmux send-keys -t gt-gastown-toast "{{nudge_text}}" Enter
```

**pre-kill-verify**:
```bash
cd polecats/toast
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred
```
If clean: kill session, remove worktree, delete branch
If dirty: record failure, retry next cycle

**escalate**:
```bash
gt mail send mayor/ -s "Escalation: toast stuck" -m "..."
```

**none**: No action needed.

Record: action taken, result, updated nudge count.
Needs: decide

## Output

The arm completes with:
- action_taken: none | nudge-1 | nudge-2 | nudge-3 | killed | escalated
- result: success | failed | pending
- updated_state: New nudge count and timestamp for toast

This data feeds back to the parent patrol's aggregate step.

Design: Failure modes and recovery

Document failure modes and recovery strategies for Gas Town operations.

## Critical Failure Modes

### 1. Agent Crash Mid-Operation

**Scenario**: Polecat crashes while committing, Witness crashes while verifying

**Detection**:
- Session suddenly gone (tmux check fails)
- State shows 'working' but no session
- Heartbeat stops (for Witness)

**Recovery**:
- Doctor detects via ZombieSessionCheck
- Capture any recoverable state
- Reset agent state to 'idle'
- For Witness: auto-restart via supervisor or manual gt witness start

### 2. Git State Corruption

**Scenario**: Merge conflict, failed rebase, detached HEAD

**Detection**:
- Git commands fail
- Dirty state that won't commit
- Branch diverged from origin

**Recovery**:
- gt doctor reports git health issues
- Manual intervention recommended
- Severe cases: remove clone, re-clone

### 3. Beads Sync Conflict

**Scenario**: Two polecats modify same issue

**Detection**:
- bd sync fails with conflict
- Beads tombstone mechanism handles most cases

**Recovery**:
- Beads has last-write-wins semantics
- bd sync --force in extreme cases
- Issues may need manual dedup

### 4. Tmux Failure

**Scenario**: Tmux server crashes, socket issues

**Detection**:
- All sessions inaccessible
- "no server running" errors

**Recovery**:
- Kill any orphan processes
- tmux kill-server && tmux start-server
- All agent states reset to idle
- Re-spawn active work

### 5. Claude API Issues

**Scenario**: Rate limits, outages, context limits

**Detection**:
- Sessions hang or produce errors
- Repeated failure patterns

**Recovery**:
- Exponential backoff (handled by Claude Code)
- For context limits: session cycling (mail-to-self)
- For outages: wait and retry

### 6. Disk Full

**Scenario**: Clones, logs, or beads fill disk

**Detection**:
- Write operations fail
- git/bd commands error

**Recovery**:
- Clean up logs: rm ~/.gastown/logs/*
- Remove old polecat clones
- gt doctor --fix can clean some cruft

### 7. Network Failure

**Scenario**: Can't reach GitHub, API servers

**Detection**:
- git fetch/push fails
- Claude sessions hang

**Recovery**:
- Work continues locally
- Queue pushes for later
- Sync when connectivity restored

## Recovery Principles

1. **Fail safe**: Prefer stopping over corrupting
2. **State is recoverable**: Git and beads have recovery mechanisms
3. **Doctor heals**: gt doctor --fix handles common issues
4. **Emergency stop**: gt stop --all as last resort
5. **Human escalation**: Some failures need Overseer intervention

## Implementation

- Document each failure mode in architecture.md
- Ensure doctor checks cover detection
- Add recovery hints to error messages
- Log all failures for debugging

MQ conflict prediction: file hotspot tracking

Track which files change frequently to predict conflicts before spawn.

## Goal
Before spawning a polecat on an issue, warn if the target files are "hot" (recently changed by other MRs).

## Approach
1. Track file change frequency per MR (sliding window, e.g., last 24h)
2. At spawn time, analyze issue description / planned changes
3. If touching hot files, either:
   - Warn and proceed
   - Suggest waiting for queue to clear
   - Auto-assign to ownership zone (future)

## Implementation
- Add file_changes log to refinery state (or separate hotspot.json)
- After each merge, record changed files with timestamp
- gt spawn checks hotspots before assignment
- Optional: Witness patrol aggregates hotspot data

## Example
```
$ gt spawn --issue gt-xyz
Warning: This issue likely touches auth/login.go
  - Changed 3 times in last 2 hours
  - 2 MRs pending that also touch this file
Proceed anyway? [y/N]
```

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


Update architecture.md: Engineer role and Beads merge queue

Update docs/architecture.md with recent design decisions:

1. Agent table: Change "Refinery" role to "Engineer"
   - Refinery = place/module/directory
   - Engineer = role (agent that works in the Refinery)

2. Merge Queue section: Document Beads-native model
   - MRs are beads issues with --type=merge-request
   - gt mq commands (submit, list, next, process, reorder)
   - Ordering via depends-on links

3. CLI section: Add gt mq commands

4. Key Design Decisions: Add decisions for:
   - #15: Merge Queue in Beads
   - #16: Engineer role (distinct from Refinery place)
   - #17: Session restart protocol for Engineer

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.

## Key Questions

1. How are org formulas discovered? (search path? explicit import?)
2. How do aspects merge across levels?
3. Can child override parent aspects?
4. How to handle aspect conflicts?

## Proposed Design

- Formulas use extends: just like today
- Aspect lists merge (child appends to parent)
- Child can exclude parent aspects via "exclude-aspects: [name]"
- Search path: local -> rig -> org (configurable)

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)

Witness Plugin System

Patrol extensions via molecule bonding.

## Core Insight

Plugins ARE molecules. No separate format needed.

## How It Works

```
mol-witness-patrol
    │
    ├── survey-workers
    │
    ├── plugin-run ←── bonds registered plugin molecules
    │       │
    │       ├── mol-mood-check (if registered)
    │       ├── mol-security-scan (if registered)
    │       └── mol-custom-X (user-installed)
    │
    └── aggregate (WaitsFor: all-children)
```

## Plugin Molecule Structure

A plugin is just a molecule proto with specific labels:

```json
{
  "id": "mol-mood-check",
  "title": "Polecat Mood Check",
  "description": "Assess polecat emotional state from output. Vars: {{polecat_name}}, {{captured_output}}",
  "labels": ["template", "plugin", "witness", "tier:haiku"],
  "issue_type": "task"
}
```

Labels encode metadata:
- `plugin` - marks as bondable plugin
- `witness` / `deacon` / `refinery` - which patrol can use it
- `tier:haiku` / `tier:sonnet` - model tier hint

## Registration

Plugins registered in rig config or molecules.jsonl:

```bash
# Install from Mol Mall
bd mol install mol-mood-check

# Or add to ~/.beads/molecules.jsonl manually
```

## Execution

The `plugin-run` step in patrol:

```bash
# For each registered plugin molecule matching this patrol:
bd mol bond mol-mood-check $PATROL_WISP \
  --ref mood-{{polecat_name}} \
  --var polecat_name=$POLECAT \
  --var captured_output="$OUTPUT"
```

## CLI

- `bd mol list --label plugin` - List available plugins
- `bd mol install <id>` - Install from Mol Mall
- `gt patrol plugins <role>` - Show plugins for a patrol role

## Benefits

- No YAML schema to maintain
- No separate plugin loading code
- Plugins are versioned, synced, auditable (they are beads)
- Distribution via Mol Mall (molecules.jsonl registry)
- Same {{var}} substitution as all molecules

Epic: Fix swarm orchestration - witness/refinery/polecat lifecycle

## Problem Statement

The bd-9115 swarm execution required excessive manual intervention from Mayor. The witness, refinery, and polecat lifecycle components didn't coordinate automatically.

## What Should Have Happened

```
Mayor slings 6 beads to rig
    ↓
Polecats auto-spawn with synced beads, work pinned
    ↓
Polecats work autonomously
    ↓
Witness monitors progress, nudges stuck polecats
    ↓
Polecat completes → pushes branch → signals completion
    ↓
Refinery detects ready branch → rebases → merges → deletes branch
    ↓
Witness detects merge → nukes polecat worktree
    ↓
When all done → Witness notifies Mayor
```

## What Actually Happened

1. **gt sling failed to pin beads** - polecat worktrees had stale JSONL
2. **Manual intervention** - had to checkout latest JSONL, pin, nudge each polecat
3. **Witness was passive** - never nudged or checked on polecats
4. **Refinery waited for requests** - didn't detect completed branches
5. **Manual lifecycle** - Mayor had to close beads, nuke polecats
6. **Manual merge coordination** - had to mail refinery with merge order

## Root Cause: Branch Hysteresis

Polecat branches persist across runs and drift from main/beads-sync:
- `polecat/foo` created weeks ago from old main
- New work slung to `polecat/foo`
- JSONL in branch doesn't have new beads
- Pin fails

## Open Questions

### Q1: Fresh branches per run?
Should each polecat spawn create a NEW branch from latest main/beads-sync?
```
gt sling bd-xxx rig
  → creates polecat/foo-20251227-1630 from origin/main
  → ensures JSONL is current
  → after merge, branch deleted forever
```
Pros: No drift, always current
Cons: Branch proliferation, naming complexity

### Q2: Rebase existing branches?
Or should we rebase persistent polecat branches before work?
```
gt sling bd-xxx rig/foo
  → git fetch origin
  → git rebase origin/main
  → now JSONL is current
```
Pros: Keeps simple naming
Cons: Rebase can fail with conflicts

### Q3: Just cherry-pick JSONL?
Minimal fix - grab latest JSONL before pinning:
```
git checkout origin/beads-sync -- .beads/issues.jsonl
bd import  # refresh DB
bd pin bd-xxx
```
Pros: Simple, surgical
Cons: Doesn't fix code drift, just beads

### Q4: Shared beads DB?
Could polecats share a DB (via symlink or sqlite over network)?
Pros: Always consistent
Cons: Locking complexity, daemon conflicts

### Q5: Who owns polecat lifecycle?
- Witness? (current assumption)
- Refinery? (after merge)
- gt sling? (on spawn)
- New "foreman" role?

```go
package session

import "fmt"

const Prefix = "gt-"

func MayorSessionName() string { return Prefix + "mayor" }

Add logging for silently ignored errors

attached_args: Add logging for silently ignored errors

Add logging for silently ignored errors.

## Problem
Many places use `_ =` pattern to ignore errors without any logging, making debugging difficult.

## Files to modify
- internal/cmd/start.go (lines 167, 322-323, 429, 747-753, 886-888)
- internal/cmd/polecat.go (search for `_ =`)
- internal/session/manager.go (lines 140-154)
- internal/refinery/manager.go (line 399)
- internal/keepalive/keepalive.go (document as intentional)

## Implementation options

### Option A: Add comments explaining safety
```go
_ = m.saveState(ref) // Non-fatal: state will be recreated on next run
```

### Option B: Log warnings (preferred for important operations)
```go
if err := m.saveState(ref); err != nil {
    log.Printf("warning: failed to save state: %v", err)
}
```

## Guidelines
- Use logging for: state saves, config writes, cleanup operations
- Use comments for: truly benign operations (e.g., closing already closed file)
- keepalive is intentionally best-effort - add package-level comment

## Acceptance criteria
- [ ] All `_ =` in start.go have comment OR logging
- [ ] All `_ =` in session/manager.go have comment OR logging
- [ ] refinery/manager.go:399 has logging
- [ ] keepalive package has doc comment explaining best-effort design
- [ ] grep '`_ =`' shows all have justification
- [ ] go build ./... passes

gt spawn: Notify Deacon and Witness on polecat start

When gt spawn creates a polecat, it should mail both Deacon and Witness:

```
gt mail send <rig>/witness -s 'POLECAT_STARTED furiosa' -m 'Issue: gt-xxx'
gt mail send deacon/ -s 'POLECAT_STARTED gastown/furiosa' -m 'Issue: gt-xxx'
```

This enables:
- Witness to bond a lease to its patrol wisp
- Deacon to verify worker started (redundancy)
- Both to nudge if worker is idle at prompt

Swarm-in-Beads: Discovery-based swarm execution

Swarm-in-Beads: Make swarm state derive from beads, not separate JSON. See ~/gt/docs/swarm-architecture.md for full design. Core principles: discovery over tracking, ready front model, nondeterministic idempotence.


Polecat Role Definition

You are a Polecat - an autonomous worker assigned to a specific issue.

You work independently, following the mol-polecat-work formula, and signal
completion to your Witness. You are transient - spawned for work, cleaned up
after completion.

default_molecule: mol-polecat-work
capabilities:
  - execute_assigned_work
  - git_operations
  - branch_management
  - completion_signaling

## Core Responsibilities

1. Execute your pinned molecule's steps
2. Maintain clean git state
3. Signal completion via gt done
4. Wait for Witness to handle lifecycle

## You Do NOT

- Push directly to main (Refinery merges)
- Kill your own session (Witness does cleanup)
- Skip verification steps
- Work on anything other than your assigned issue

## Propulsion Principle

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

Your work is defined by your pinned molecule. Execute steps:
- bd ready (find next step)
- bd show <step-id> (see what to do)
- bd close <step-id> (mark complete)

## Completion Protocol

When done:
1. Tests pass: go test ./...
2. COMMIT changes: git add && git commit
3. Push branch: git push -u origin HEAD
4. Close issue: bd close <issue>
5. Sync beads: bd sync
6. Run gt done
7. WAIT: Witness will kill your session

## Communication

Mail your Witness when stuck:
gt mail send <rig>/witness -s "HELP: <problem>" -m "..."

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


Unified Beads Namespace - prefix-based routing across town

Vision: Run bd commands from anywhere in town, with prefix-based routing.

Current state:
- Town beads at ~/gt/.beads/ with hq-* prefix
- Rig beads at ~/gt/<rig>/mayor/rig/.beads/ with rig-specific prefixes (gt-, bd-, wy-, etc.)
- Redirects allow agents to use specific beads location
- No automatic prefix-based routing

Desired state:
- bd show gt-xyz from ANYWHERE in town → routes to gastown beads
- bd show hq-abc from ANYWHERE in town → routes to town beads
- bd show wy-def from ANYWHERE in town → routes to wyvern beads
- Prefix determines beads location automatically

Implementation options:
1. Registry file at town root mapping prefix → beads location
2. bd wrapper/hook that reads prefix and routes
3. Unified store with namespace prefixes (more invasive)

3. Reset to ready state
4. Optionally re-run immediately (--now flag)

Options:
- --now: immediately process (instead of waiting for Engineer loop)

Test Patrol Parent

Test parent for Christmas Ornament pattern


Refinery Role Definition

You are the Refinery - merge queue processor for your rig. You process
completed polecat work, merging it to main one branch at a time with
sequential rebasing.

Your mission: Process the merge queue sequentially, rebasing each branch
atop the current baseline before merging.

default_molecule: mol-refinery-patrol
capabilities:
  - merge_queue_processing
  - sequential_rebase
  - conflict_resolution
  - verification_gates

## The Engineer Mindset

You are Scotty in the engine room. The merge queue is your warp core.

The Beads Promise: Work is never lost. If you discover ANY problem:
1. Fix it now (preferred if quick), OR
2. File a bead and proceed (tracked for cleanup crew)

There is NO third option. Never "disavow" by noting something exists and moving on.

The Scotty Test: Before proceeding past any failure, ask yourself:
"Would Scotty walk past a warp core leak because it existed before his shift?"

## Propulsion Principle

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

Your work is defined by the mol-refinery-patrol molecule. Execute steps:
- bd ready (find next step)
- bd show <step-id> (see what to do)
- bd close <step-id> (mark complete)

## Sequential Rebase Protocol

WRONG (parallel merge - causes conflicts):
  main -> branch-A (old main) + branch-B (old main) = CONFLICTS

RIGHT (sequential rebase):
  main -> merge A (rebased on main) -> merge B (rebased on main+A)

After every merge, main moves. Next branch MUST rebase on new baseline.

## Verification Gate

The handle-failures step is a verification gate:
- Tests PASSED: Gate satisfied, proceed to merge
- Tests FAILED (branch caused): Abort, notify polecat, skip branch
- Tests FAILED (pre-existing): MUST fix OR file bead - cannot proceed without

## Commands

### Patrol
- gt mol status - Check attached patrol
- bd ready / bd show / bd close - Step management
- bd mol spawn <mol> --wisp - Spawn patrol wisp

### Git Operations
- git fetch origin - Fetch all remote branches
- git branch -r | grep polecat - List polecat branches
- git rebase origin/main - Rebase on current main
- git push origin main - Push merged changes

### Communication

CloudRun protocol types: WorkRequest, WorkEvent, WorkResult

## Overview

HTTP protocol types for Cloud Run work dispatch. **Types only** - server and client are separate tasks.

## Request Type

```go
type WorkRequest struct {
    IssueID string          `json:"issue_id"`
    Rig     RigConfig       `json:"rig"`
    Beads   BeadsConfig     `json:"beads"`
    Branch  string          `json:"worker_branch"`
    Context map[string]any  `json:"context,omitempty"`
}

type RigConfig struct {
    URL    string `json:"url"`
    Branch string `json:"branch"`
}

type BeadsConfig struct {
    URL    string `json:"url"`
    Branch string `json:"branch"`
}
```

## Response Types (streaming NDJSON)

```go
type WorkEvent struct {
    Type     string `json:"type"`  // status, log, progress, result, error
    Status   string `json:"status,omitempty"`
    Line     string `json:"line,omitempty"`
    Percent  int    `json:"percent,omitempty"`
    Branch   string `json:"branch,omitempty"`
    PRURL    string `json:"pr_url,omitempty"`
    Code     string `json:"code,omitempty"`
    Message  string `json:"message,omitempty"`
}

type WorkResult struct {
    Status  string `json:"status"`  // done, failed
    Branch  string `json:"branch"`
    PRURL   string `json:"pr_url,omitempty"`
    Error   string `json:"error,omitempty"`
}
```

## Files

- `internal/cloudrun/protocol.go` - All types above

## Notes

This is just types. Server (gt-9a2.7b) and client (gt-9a2.7c) are separate tasks.
Small, focused task - can complete quickly.


Daemon heartbeat: worker and queue monitoring

Daemon periodic checks for work progress.

## Heartbeat Actions

Every N seconds (configurable):

1. Check Witness health per rig
   - Poke if witness needs to nudge workers

2. Check Refinery queue per rig
   - Poke if pending work in queue

3. Check work completion
   - If epic children all closed, notify Mayor

## Eventually Convergent

Multiple signals reinforce state:
- Polecat signals done → Witness notices → pokes Refinery
- Daemon heartbeat → checks queue → pokes Refinery
- Beads status → queryable by any agent

Even if one signal missed, system converges.

## Interface

```go
func (d *Daemon) HeartbeatLoop() {
    for {
        for _, rig := range d.rigs {
            d.CheckWitness(rig)
            d.CheckRefinery(rig)
            d.CheckWorkProgress(rig)
        }
        time.Sleep(d.config.HeartbeatInterval)
    }
}
```

## Notifications

Use mail with low priority for heartbeat pokes.
Agents can ignore if already processing.

gt park command for parking molecules on external deps

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

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

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

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

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

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

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)

- Get cwd
- Find workspace
- Parse target argument
- Determine rig from address or role

## Implementation
Extract helper function:
```go

    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 {

    }
    if townRoot == "" {
        return nil, fmt.Errorf("not in a Gas Town workspace")
    }
    // ... rest of target detection logic ...
}
```

## Acceptance criteria

gt crew remove: Does not close agent bead

When running 'gt crew remove <name>', the command removes the crew workspace directory but does not close the associated agent bead (gt-<rig>-crew-<name>).

This leaves orphaned agent beads in the system after crew removal.

The remove command should close the agent bead with a reason like 'Crew workspace removed'.


Remove lifecycle intent parsing from Go

daemon/lifecycle.go parses mail subjects with regex looking for restart/shutdown/cycle keywords, then executes actions. Fix: use structured message types in mail body instead of parsing subjects. Go reads action field, does not interpret text.


Molecule Algebra: Work Composition DSL

Implement the molecule algebra - a declarative language for composing, transforming, and executing structured work. Enables mechanical composition without AI.

The Three Phases: Rig → Cook → Run

- **Rig**: Source-level composition (formula YAML with extends/compose)
- **Cook**: Instantiation (formula → proto → mol/wisp)
- **Run**: Execution (agents complete steps)

Two Composition Operators:
- **Rig** operates on formulas (source level)
- **Bond** operates on artifacts (protos, mols, wisps)

Key components:
- Formulas: YAML source with composition rules (.formula.yaml)
- Cook: Pre-expand macros/aspects to flat proto
- Phase verbs (pour, wisp)
- Bond: Artifact-level polymorphic composition
- Composition operators (sequence, parallel, branch, loop, gate)
- Advice operators (before, after, around - Lisp style)
- Expansion operators (macros like Rule of Five)
- Aspects (AOP cross-cutting concerns)

See docs/rig-cook-run.md for the lifecycle spec.
See docs/molecule-algebra.md for full algebra specification.

No-tmux mode: naked Claude Code operation without daemon/tmux

## Problem

Tmux is crashing workers. The daemon relies on tmux for:
- Session management (creating/killing panes)
- Nudging agents via SendKeys
- Crash detection via pane-died hooks

When tmux is unstable, the entire Gas Town operation fails.

## Goal

Enable Gas Town to operate without tmux or the daemon, relying solely on:
- Naked Claude Code sessions (terminal or IDE)
- Deacon self-handoff and patrol robustness
- Pinned beads for propulsion (already implemented)
- **Beads as universal data plane** - args, context, everything flows through beads

## Key Insight: Beads Replace SendKeys

Currently --args is injected via tmux SendKeys. In no-tmux mode:
- Store args in the pinned bead description (attached_args field)
- gt prime reads and displays args from pinned bead
- Wisps are infinite ephemeral sticky notes - use them for transient context
- No prompt injection needed - agent discovers everything via bd show

## Degraded Behavior (No-Tmux Mode)

**What still works:**
- Propulsion via pinned beads (agents pick up work on startup)
- Self-handoff (agents can cycle themselves)
- Patrol loops (Deacon, Witness, Refinery keep running)
- Mail system (beads-based, no tmux needed)
- Args passed via bead description

**What is degraded:**
- **No interrupts**: Cannot nudge busy agents mid-task
- **Polling only**: Agents must actively check inbox (no push notifications)
- **Await steps block**: "Wait for human" steps require manual agent restart
- **No crash detection**: pane-died hooks unavailable
- **Manual startup**: Human must start each agent in separate terminal

**Workflow implications:**
- Patrol agents work fine (they poll as part of their loop)
- Task workers need restart to pick up new work
- Cannot redirect a busy worker to urgent task
- Human must monitor and restart crashed agents

## Requirements

1. **gt sling --args stores in bead**: Write args to pinned bead description
2. **gt prime displays args**: Read attached_args from pinned bead
3. **gt spawn --naked**: Assign work without creating tmux session
4. **Documentation**: Explain no-tmux mode and degraded behavior
5. **Deacon self-sustaining**: Must cycle reliably without daemon

## Acceptance Criteria

- Can assign work with args without tmux
- Agent discovers args via gt prime / bd show on startup
- Deacon patrol runs indefinitely via self-handoff
- Workers started manually pick up pinned work
- Documentation explains what works vs degraded in no-tmux mode

Patrol #14


mol-crew-session: Startup/shutdown protocols for crew workers

Crew workers (like joe, max) don't have patrol molecules keeping them fresh. When gt gets rebuilt, they have stale binaries that cause hangs and bugs.

## Problem

- Crew binaries get stale when gt is rebuilt elsewhere
- No automatic pull/rebase/rebuild on session start
- No standardized shutdown protocol (sync, push, handoff)

## Solution: mol-crew-session

A molecule template for crew sessions:

### Startup Phase
1. `git pull --rebase` - get latest code
2. `bd sync` - sync beads
3. `go build -o gt ./cmd/gt` - rebuild gt (if in gastown)
4. `gt prime` - load context

### Work Phase
- Open-ended human interaction
- No molecule steps - just work until done

### Shutdown Phase
1. `git status` - check for uncommitted changes
2. `bd sync` - sync beads
3. `git push` - push code
4. Handoff if incomplete work

## Implementation

1. Define mol-crew-session in builtin_molecules.go
2. Update crew CLAUDE.md to reference the protocol
3. Optionally: gt prime auto-runs startup steps

Rollback support: gt mq revert for problematic merges

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

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

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

Track revert in MR metadata for audit trail.

Nudge newly spawned polecats

Nudge newly spawned polecats that are ready for input.

When polecats are spawned, their Claude session takes 10-20 seconds to initialize.
The spawn command returns immediately without waiting. This step finds spawned
polecats that are now ready and sends them a trigger to start working.

```bash
# For each rig with polecats
for rig in gastown beads; do
    gt polecats $rig
    # For each working polecat, check if Claude is ready
    # Use tmux capture-pane to look for "> " prompt
done
```

For each ready polecat that hasn't been triggered yet:
1. Send "Begin." to trigger UserPromptSubmit hook
2. The hook injects mail, polecat sees its assignment
3. Mark polecat as triggered in state

Use WaitForClaudeReady from tmux package (polls for "> " prompt).
Timeout: 60 seconds per polecat. If not ready, try again next cycle.

Plugin system: subprocess JSON protocol

Language-agnostic plugin system via subprocess JSON protocol.

## Concept

Allow extending Gas Town with external scripts/programs. Plugins communicate via stdin/stdout JSON.

## Protocol

Request (gt → plugin):
```json
{"method": "check", "params": {"rig": "wyvern", "polecat": "Toast"}}
```

Response (plugin → gt):
```json
{"result": {...}, "error": null}
```

Error response:
```json
{"result": null, "error": {"code": 1, "message": "..."}}
```

## Interface

```go
type Plugin struct {
    Name    string
    Path    string  // executable path
    Methods []string
}

type PluginManager struct {
    plugins map[string]*Plugin
}

func NewPluginManager() *PluginManager
func (pm *PluginManager) Register(plugin *Plugin) error
func (pm *PluginManager) Call(plugin, method string, params any) (any, error)
func (pm *PluginManager) Discover(dir string) error  // auto-discover plugins
```

## Plugin Discovery

Look in:
1. `<town>/plugins/`
2. `~/.config/gastown/plugins/`
3. System path with `gt-plugin-*` prefix

## Built-in Hooks

Plugins can register for events:
- `polecat.started` - Polecat session started
- `polecat.done` - Polecat signals done
- `merge.requested` - MR submitted
- `merge.completed` - MR merged

## Use Cases

- Custom health checks
- Integration with external systems (Slack, etc.)
- Custom merge policies
- Metrics collection

## Future

Consider MCP integration for richer plugin capabilities.

Implement await type handlers (gh:run, gh:pr, timer, human, mail)

Implement condition checking for each await type.

## Handlers Needed
- gh:run:<id> - Check GitHub Actions run status via gh CLI
- gh:pr:<id> - Check PR merged/closed status via gh CLI
- timer:<duration> - Simple elapsed time check
- human:<prompt> - Check for human approval (via mail?)
- mail:<pattern> - Check for mail matching pattern

Move polecat pending tracking from Deacon to Witness

Problem: gt deacon pending handles polecat observation at the wrong level. Hierarchy should be Witness→polecats, Deacon→Witnesses.

Solution:
1. Add gt witness pending - shows pending polecats in this rig
2. Route POLECAT_STARTED mail to Witness (not just Deacon)
3. Deacon keeps backup role but does not directly manage polecats

Depends on gt-0yqqw (messaging infrastructure) for proper routing.

Startup hook should validate attached molecule is still open

When the SessionStart hook outputs attached_molecule from the handoff bead, it should check if that molecule is still open. If closed, it should:
1. Clear the stale attachment
2. Auto-spawn a fresh patrol molecule
3. Attach the new patrol

Currently it just outputs the stale reference without validation, leaving the Deacon confused about what to run.


Add hook-singleton doctor check

Add gt doctor check to ensure each agent has at most one handoff bead.

Check: hook-singleton
Error if: Multiple pinned beads with same '{role} Handoff' title

Add neighbor-check steps to all patrol molecules

Part of the 'Gas Town is a Village' antifragility design.

Every patrol molecule should include optional neighbor-checking:
- Deacon checks Witness and Refinery health
- Witness checks Refinery health
- Refinery checks Witness health
- Polecats can peek other polecats

Use gt peek to check health states.
If stuck neighbor found, can nudge or escalate.

This creates distributed monitoring - no single point of failure.

Dynamic arm bonding in witness patrol

Witness survey step uses bd mol bond to attach mol-polecat-arm for each active worker. Variables: worker name, rig. Arms become children of the patrol molecule. Requires on_complete/for_each runtime support.


list: static mailing list lookup

Static mailing list support via config file.

## Deliverables

1. Load lists from ~/gt/config/lists.json
2. Parse list:name syntax in router
3. Fan-out at send time (same as @group)
4. Error handling for unknown list names

## Example
```bash
gt mail send list:oncall -s "Alert" -m "System down"
# 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

## Test cases to cover
1. Lock() acquires lock successfully
2. Lock() blocks when lock held by another
3. Unlock() releases lock
4. TryLock() returns immediately if locked
5. IsLocked() detects lock state
6. Lock file contains correct PID
7. Stale lock detection (if implemented)

## Acceptance criteria
- [ ] internal/lock/lock_test.go created
- [ ] At least 5 test functions
- [ ] Tests pass: go test ./internal/lock/...
- [ ] Coverage > 70%: go test -cover ./internal/lock/...

gt doctor: detect orphaned code on beads-sync branch

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

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

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

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

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


Bug: LIFECYCLE messages use literal <rig> placeholder

Remove all hardcoded gastown dependencies from gt codebase

The Go codebase should not have hardcoded dependencies on gastown (the rig name).

Found in prime.go outputDeaconPatrolContext() - FIXED in this session.

Other potential issues to audit:
- Check all patrol context functions (Witness, Refinery) for similar patterns
- Ensure rig-specific paths are derived from context, not hardcoded
- Test with a different rig name to verify

The principle: Gas Town should work with any rig name, not just gastown.

CLI: mail commands (send, inbox, read)

CLI: mail commands wrapping bd mail.

## Status

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

## Commands

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

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

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

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

## Address Translation

Polecat Arm (arm-toast)

Single polecat inspection and action cycle.

This molecule is bonded dynamically by mol-witness-patrol's survey-workers step.
Each polecat being monitored gets one arm that runs in parallel with other arms.

## Variables

| Variable | Required | Description |
|----------|----------|-------------|
| polecat_name | Yes | Name of the polecat to inspect |
| rig | Yes | Rig containing the polecat |

## Step: capture
Capture recent tmux output for toast.

```bash
tmux capture-pane -t gt-gastown-toast -p | tail -50
```

Record:
- Last activity timestamp (when was last tool call?)
- Visible errors or stack traces
- Completion indicators ("Done", "Finished", etc.)

## Step: assess
Categorize polecat state based on captured output.

States:
- **working**: Recent tool calls, active processing
- **idle**: At prompt, no recent activity
- **error**: Showing errors or stack traces
- **requesting_shutdown**: Sent LIFECYCLE/Shutdown mail
- **done**: Showing completion indicators

Calculate: minutes since last activity.
Needs: capture

## Step: load-history
Read nudge history for toast from patrol state.

```
nudge_count = state.nudges[toast].count
last_nudge_time = state.nudges[toast].timestamp
```

This data was loaded by the parent patrol's load-state step and passed
to the arm via the bonding context.
Needs: assess

## Step: decide
Apply the nudge matrix to determine action for toast.

| State | Idle Time | Nudge Count | Action |
|-------|-----------|-------------|--------|
| working | any | any | none |
| idle | <10min | any | none |
| idle | 10-15min | 0 | nudge-1 (gentle) |
| idle | 15-20min | 1 | nudge-2 (direct) |
| idle | 20+min | 2 | nudge-3 (final) |
| idle | any | 3 | escalate |
| error | any | any | assess-severity |
| requesting_shutdown | any | any | pre-kill-verify |
| done | any | any | pre-kill-verify |

Nudge text:
1. "How's progress? Need any help?"
2. "Please wrap up soon. What's blocking you?"
3. "Final check. Will escalate in 5 min if no response."

Record decision and rationale.
Needs: load-history

## Step: execute
Take the decided action for toast.

**nudge-N**:
```bash
tmux send-keys -t gt-gastown-toast "{{nudge_text}}" Enter
```

**pre-kill-verify**:
```bash
cd polecats/toast
git status                    # Must be clean
git log origin/main..HEAD     # Check for unpushed
bd show <assigned-issue>      # Verify closed/deferred
```
If clean: kill session, remove worktree, delete branch
If dirty: record failure, retry next cycle

**escalate**:
```bash
gt mail send mayor/ -s "Escalation: toast stuck" -m "..."
```

**none**: No action needed.

Record: action taken, result, updated nudge count.
Needs: decide

## Output

The arm completes with:
- action_taken: none | nudge-1 | nudge-2 | nudge-3 | killed | escalated
- result: success | failed | pending
- updated_state: New nudge count and timestamp for toast

This data feeds back to the parent patrol's aggregate step.

Use atomic write pattern for state files

attached_args: Atomic write pattern for state files

Prevent data loss from concurrent state file writes using atomic write pattern.

## Files to modify
- internal/witness/manager.go
- internal/refinery/manager.go
- internal/crew/manager.go
- internal/swarm/manager.go

## Problem
State is saved directly to file - if process crashes mid-write, file corrupts.

## Implementation
Replace direct writes with atomic pattern:
```go
func atomicWriteJSON(path string, v interface{}) error {
    data, err := json.MarshalIndent(v, "", "  ")
    if err != nil {
        return err
    }
    tmpFile := path + ".tmp"
    if err := os.WriteFile(tmpFile, data, 0644); err != nil {
        return err
    }
    return os.Rename(tmpFile, path)  // Atomic on POSIX
}
```

## Acceptance criteria
- [ ] atomicWriteJSON helper created (in internal/util or similar)
- [ ] All 4 manager saveState methods use atomic writes
- [ ] .tmp files cleaned up on success
- [ ] go test ./... passes
- [ ] Manual test: state files survive kill -9


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.


Wire up created_by field for beads issues

## Goal
Add actor/creator attribution to beads issues created by gastown.

## Done
- Added CreatedBy field to Issue struct
- Added Actor field to CreateOptions
- Pass --actor to bd create

## Remaining
1. Add ActorString() method to RoleInfo
2. Update beads.Create() callers to pass Actor
3. Update direct bd create exec calls to add --actor

## Context
Beads GH #748 added created_by field. Gastown needs to populate it.
