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.


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.


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.

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.


Daemon patrol should clean stale locks

The gt daemon patrol cycle should detect and clean up stale locks.

## Problem
If daemon crashes or there are orphaned locks, they can block operations indefinitely.

## Proposed Solution
During patrol cycle:
1. Check for lock files older than threshold (e.g., 5 minutes)
2. Verify owning process is dead (check PID if stored)
3. Remove stale locks
4. Log cleanup for audit

Remove bd sync instruction from polecat startup workflow

Polecats are instructed to run `bd sync --from-main` on startup (spawn.go:634).

## Problem
- Spawn command already syncs beads before spawning (line 239)
- Polecats share rig-level beads via `.beads/redirect`
- Multiple polecats starting simultaneously all try to sync same shared beads
- This causes git conflicts/failures when many polecats spawn at once

## Observed
User reported: 'all polecats failing on beads sync on startup in one run'

## Fix
Remove line 634 from buildWorkAssignmentMail():
```
body.WriteString("2. Run \`bd sync --from-main\` to get fresh beads\n")
```

Polecats only need to sync at END of work (already in steps 5/7).

Async Coordination Gates

Agents wait for external events without polling.

## Problem
Agents cannot wait for external conditions (CI completion, human approval, timers) without wasteful polling or losing state on handoff.

## Requirements
- Gate issue type in beads (type=gate)
- bd gate create --await timer:5m / gh:run:123 / human:approve / mail:pattern
- Deacon evaluates pending gates each patrol cycle
- Agents park work on gate, resume when condition met
- Gate timeout and notification

## Gate Types
- timer:<duration> - Simple delay (5m, 1h, 24h)
- gh:run:<id> - GitHub Actions run completion
- gh:pr:<id> - PR merged/closed
- human:<prompt> - Human approval required
- mail:<pattern> - Wait for mail matching pattern

## Success Criteria
- Agent can create gate and suspend work
- Deacon wakes agent when gate condition met
- Gates survive session cycling

Consolidates gt-31eg. Parallel work with no dependencies.

Check Witness and Refinery health

Check Witness and Refinery health for each rig.

**ZFC Principle**: You (Claude) make the judgment call about what is "stuck" or "unresponsive" - there are no hardcoded thresholds in Go. Read the signals, consider context, and decide.

For each rig, run:
```bash
gt witness status <rig>
gt refinery status <rig>
```

**Signals to assess:**

| Component | Healthy Signals | Concerning Signals |
|-----------|-----------------|-------------------|
| Witness | State: running, recent activity | State: not running, no heartbeat |
| Refinery | State: running, queue processing | Queue stuck, merge failures |

**Tracking unresponsive cycles:**

Maintain in your patrol state (persisted across cycles):
```
health_state:
  <rig>:
    witness:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
    refinery:
      unresponsive_cycles: 0
      last_seen_healthy: <timestamp>
```

**Decision matrix** (you decide the thresholds based on context):

| Cycles Unresponsive | Suggested Action |
|---------------------|------------------|
| 1-2 | Note it, check again next cycle |
| 3-4 | Attempt restart: gt witness restart <rig> |
| 5+ | Escalate to Mayor with context |

**Restart commands:**
```bash
gt witness restart <rig>
gt refinery restart <rig>
```

**Escalation:**
```bash
gt mail send mayor/ -s "Health: <rig> <component> unresponsive" \
  -m "Component has been unresponsive for N cycles. Restart attempts failed.
      Last healthy: <timestamp>
      Error signals: <details>"
```

Reset unresponsive_cycles to 0 when component responds normally.


Day 3.0: Document mail protocol for patrol coordination

Document the mail protocol used for patrol coordination.

**Mail types:**
- POLECAT_DONE: Polecat → Witness (work complete, ready for merge)
- MERGE_READY: Witness → Refinery (branch ready for merge queue)
- MERGED: Refinery → Witness (merge complete, safe to nuke)
- WITNESS_PING: Witness → Deacon (health check for second-order monitoring)
- HELP: Any → escalation target (stuck, need intervention)
- HANDOFF: Any → self (session continuity)

**Format conventions:**
- Subject prefix indicates type (e.g., 'POLECAT_DONE: nux')
- Body contains structured data (branch, bead ID, etc.)

This documentation enables consistent implementation across all patrol formulas.


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).

Witness session cycling and handoff

Add session cycling and handoff protocol to Witness CLAUDE.md template.

## Session Cycling Protocol

```markdown
## Session Cycling

Your context will fill over long swarms. Proactively cycle when:
- Running for many hours
- Losing track of which workers you've checked
- Responses getting slower
- About to start complex operation

### Handoff Protocol

1. **Capture current state**:
```bash
town list .           # Worker states
town all beads        # Pending verifications
town inbox            # Unprocessed messages
```

2. **Compose handoff note**:
```
[HANDOFF_TYPE]: witness_cycle
[TIMESTAMP]: <now>
[RIG]: <rig>

## Active Workers
<list workers and status>

## Pending Verifications
<workers signaled done but not verified>

## Recent Actions
<last 3-5 actions>

## Warnings/Notes
<anything next session should know>

## Next Steps
<what should happen next>
```

3. **Send handoff**:
```bash
town mail send <rig>/witness -s "Session Handoff" -m "<note>"
```

4. **Exit cleanly**: End session, daemon spawns fresh one.

### On Fresh Session Start

1. Check for handoff: `town inbox | grep "Session Handoff"`
2. If found, read it and resume from handoff state
3. If not found, do full status check
```

## Implementation

Add to WITNESS_CLAUDE.md template.

   - 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

Molecule execution support for polecats and crew

Enable agents to run bonded molecules through the full lifecycle.

## The Model
1. BOND - bd mol bond <template> --assignee <identity>
   Creates concrete issues, assigns root to agent

2. DISCOVER - Agent finds assigned molecules via bd ready
   DAG structure shows unblocked steps

3. WORK - Agent works through DAG, closing steps as done
   Can delegate children to lower-tier agents (haiku)

4. SURVIVE - Agent dies → beads persist
   Any agent resumes from DAG state

5. SUPERVISE - Witness monitors for stalled molecules
   Nudges owner or reassigns if dead

## Questions to Resolve
- Seed node terminology: seed vs root vs pole vs nucleus
- Assignee inheritance: single owner vs delegation model
- Stall detection: heartbeat vs activity timeout vs session monitoring

## Implementation
- Polecat startup: check for assigned molecules
- Polecat work loop: follow molecule DAG
- Witness: monitor molecule progress, detect stalls
- Mayor: can assign molecules, handle escalations

## Depends On
- beads: bd mol bond command (bd-usro in beads repo)


CLI: gt refinery commands (start, stop, status, queue)

CLI commands for managing the Refinery agent.

## Commands

```bash
gt refinery start <rig>      # Start refinery for a rig
gt refinery stop <rig>       # Stop refinery
gt refinery status <rig>     # Show refinery status
gt refinery queue <rig>      # Show merge queue
```

## gt refinery start

Starts the Refinery daemon for the specified rig.

Options:
- --foreground: Run in foreground (default: background)
- --auto-merge: Enable auto-merge (default: from config)

## gt refinery stop

Stops a running Refinery. Gracefully finishes current MR if processing.

## gt refinery status

Shows:
- Running state (running/stopped)
- Current MR being processed (if any)
- Queue length
- Last merge time
- Recent activity

## gt refinery queue

Shows the merge queue:
```
Merge queue for 'wyvern':
  1. [pending] Toast/polecat-auth-fix (15m ago)
  2. [pending] Capable/polecat-new-feature (5m ago)

1 merged today, 0 rejected
```

## Implementation

Uses gt-ov2 (Refinery agent) for daemon functionality.

Update architecture documentation

Update all documentation to reflect refinery-as-worktree model.

## Files to update
- docs/architecture.md (if exists)
- CLAUDE.md references to refinery
- mayor/rig/docs/*.md - any refinery docs
- wisp-architecture.md - add MR wisp details
- README files mentioning clone vs worktree

## Key messages
- Refinery is worktree, not clone
- Polecat branches stay local
- Only main pushed to origin
- MRs are wisps (ephemeral)


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.

Polecat .beads/ contamination from stale branches

**Fixed in commit 8699b7b**

## Problem

When polecats are spawned from branches that previously had bd sync run on them, the .beads/ directory from the branch contains stale issues.jsonl, config.yaml, etc.

The setupSharedBeads() function was creating a redirect file, but NOT cleaning up the existing .beads/ contents first.

## Root Cause

1. Old polecat branch has .beads/ tracked in git (from previous bd sync)
2. gt spawn uses Add() which reuses existing branch
3. WorktreeAddExisting() checks out branch, including .beads/ files
4. setupSharedBeads() creates redirect, but other files remain
5. bd commands see stale data

## Fix

setupSharedBeads() now:
1. Removes entire .beads/ directory if it exists
2. Recreates fresh with only redirect file
3. Redirect points directly to mayor/rig/.beads (not through rig root)

Check own context limit

Check own context limit.

The Deacon runs in a Claude session with finite context.
Check if approaching the limit:

```bash
gt context --usage
```

If context is high (>80%), prepare for handoff:
- Summarize current state
- Note any pending work
- Write handoff to molecule state

This enables the Deacon to burn and respawn cleanly.
