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


Step recovery: timeout and release

Implement recovery mechanism for stuck molecule steps.

## Problem
When a worker dies mid-step, the step stays in_progress forever.
Need timeout/release mechanism for nondeterministic idempotence.

## Solution
1. Track step start time (claimed_at timestamp)
2. Timeout: After 30 min in_progress, step returns to pending
3. Manual release: bd release <step-id>

## Implementation Options

### Option A: Beads-level timeout
- Add claimed_at field to issues
- bd ready excludes items in_progress < 30 min
- bd ready includes items in_progress > 30 min (auto-recovery)

### Option B: Daemon-level timeout
- Daemon watches in_progress items
- Moves back to pending after timeout

### Option C: Manual only (MVP)
- bd release <id> manually moves in_progress → pending
- Document recovery procedure
- Witness can automate for polecats

## Recommendation
Start with Option C (manual) for Christmas. Add Option A later.

## Acceptance
- [ ] bd release command works
- [ ] Stuck steps can be recovered
- [ ] Documented recovery procedure


Spawn --molecule integration

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

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

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

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

Files: internal/cmd/spawn.go

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

Unify warning message formatting across codebase.

## Files to modify
- internal/cmd/start.go
- internal/cmd/polecat.go
- internal/cmd/mail.go
- Any other files with inconsistent warning output

## Current inconsistency
```go

func PrintWarning(format string, args ...interface{}) {
    msg := fmt.Sprintf(format, args...)
    fmt.Printf("%s %s\n", Warning.Render("⚠ Warning:"), msg)
}
```

## Acceptance criteria
- [ ] PrintWarning helper in style package
- [ ] All warning outputs use consistent format
- [ ] Warnings go to stdout (not stderr) for consistency
- [ ] grep -rn 'Warning:' internal/cmd/ shows consistent format
- [ ] go build ./... passes

ZFC Cleanup: Move Go heuristics to Deacon molecule

Remove Go code that makes workflow decisions. All health checking, staleness
detection, nudging, and escalation belongs in the Deacon molecule where Claude
executes it once per minute.

## The Problem

Go code currently implements polling-based health inference:
- Daemon watches heartbeats with hardcoded thresholds
- Decides if agents are "stuck" based on timestamps
- Sends nudges, triggers restarts
- Parses mail subjects with regex to extract intent

This is a ZFC violation. Go should be message transport, not decision-maker.

## The Fix

Move all health/oversight logic to Deacon patrol molecule:
- Deacon runs once per minute
- Claude reads molecule steps, executes them
- Claude decides if agents are stuck (by checking mail, activity, etc.)
- Claude sends nudges/escalations via mail
- Go just routes messages

## Scope

1. daemon/daemon.go - heartbeat staleness logic
2. daemon/backoff.go - exponential backoff decisions
3. daemon/lifecycle.go - regex parsing of lifecycle intent
4. keepalive/keepalive.go - staleness thresholds
5. deacon/heartbeat.go - heartbeat age classification
6. doctor/stale_check.go - staleness detection
7. polecat/manager.go - state derivation from issues

## Success Criteria

- Go code has no hardcoded time.Duration for health decisions
- No regex parsing of mail subjects for intent
- No switch statements deciding agent state
- Deacon molecule has all oversight logic
- Go daemon is just a message router


Remove daemon heartbeat staleness logic

**Files:** daemon/daemon.go (lines 272-325), daemon/backoff.go

**Current behavior:**
- Hardcoded 2min/5min thresholds classify agent health
- Exponential backoff decides nudge intervals
- Go decides "is this agent stuck?" based on timestamps

**Fix:**
- Remove staleness classification from Go
- Remove backoff algorithm
- Daemon becomes pure message router
- Deacon molecule step checks agent health instead

**Lines to remove/refactor:**
- daemon.go:272-274 (staleness thresholds)
- daemon.go:282-295 (poke decision logic)
- daemon.go:317-325 (conditional nudging)
- backoff.go:108-120 (backoff calculations)


Remove keepalive/heartbeat staleness thresholds

**Files:**
- keepalive/keepalive.go (lines 94-111)
- deacon/heartbeat.go (lines 88-108)

**Current behavior:**
- Hardcoded thresholds: 2min=fresh, 5min=stale, 15min=very stale
- Used by daemon to decide whether to poke agents
- Go classifies agent responsiveness

**Fix:**
- Remove all hardcoded time.Duration thresholds
- Keepalive becomes pure timestamp storage
- Deacon molecule step does health assessment:
  "Check if Witness responded in last N minutes" (N from mol config)

**Lines to remove:**
- keepalive.go:96-110 (classification logic)
- heartbeat.go:91-107 (age classification)


Remove doctor staleness detection

**File:** doctor/stale_check.go (lines 11-48)

**Current behavior:**
- DefaultStaleThreshold = 1 hour hardcoded
- Scans molecules for in_progress status older than threshold
- Reports "stale" molecules automatically

**Fix:**
- Remove automatic staleness detection from doctor
- Doctor becomes pure diagnostic tool (reports facts, not judgments)
- Deacon molecule step does "orphan-check" instead:
  "Find issues in_progress with no active polecat"

**Lines to remove:**
- stale_check.go:13 (DefaultStaleThreshold constant)
- stale_check.go:243-256 (staleness classification logic)


Remove polecat state derivation from issue status

**File:** polecat/manager.go (lines 556-599)

**Current behavior:**
- Switch on issue.Status to derive polecat state
- Go decides: open/in_progress → Working, closed → Done

**Fix:**
- Polecat state comes from polecat, not inferred by Go
- Polecat signals state via mail or explicit field
- Or: remove state derivation entirely, just report issue status

**Lines to refactor:**
- manager.go:576-588 (switch statement)

**Priority:** P2 - less critical than daemon/heartbeat logic


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


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.

gt handoff: Unified agent lifecycle command

## Summary

Unified `gt handoff` command for ALL agent types to request lifecycle actions.

## Usage

gt handoff              # Context-aware default
gt handoff --shutdown   # Terminate, cleanup, don't restart
gt handoff --cycle      # Restart with handoff mail
gt handoff --restart    # Fresh restart, no handoff

## Context-Aware Defaults

| Agent Type | Default | Reason |
|------------|---------|--------|
| Polecat | --shutdown | Ephemeral, work is done |
| Witness | --cycle | Long-running, context full |
| Refinery | --cycle | Long-running, context full |
| Mayor | --cycle | Long-running, context full |
| Crew | (sends mail only) | Human-managed |

## What gt handoff Does

1. **Verify safe to stop**
   - Git state clean (no uncommitted changes)
   - Work handed off (PR exists for polecats)

2. **Send handoff mail to self** (for cycle/restart)
   - Captures current state
   - New session will read this

3. **Send lifecycle request to manager**
   - Polecats/Refinery → Witness
   - Witness/Mayor → Daemon
   - Format: mail to <manager> with action type

4. **Set state: requesting_<action>**
   - Lifecycle manager checks this before acting

5. **Wait for termination**
   - Don't self-exit - let manager kill session
   - Ensures clean handoff

## Lifecycle Request Flow

Agent                           Lifecycle Manager
  |                                    |
  | 1. gt handoff --cycle              |
  |    a. Verify git clean             |
  |    b. Send handoff mail to self    |
  |    c. Set requesting_cycle=true    |
  |    d. Send lifecycle request       |
  |------------------------------------→|
  |                                    |
  |                   2. Receive request
  |                   3. Verify state  |
  |                   4. Kill session  |
  |                   5. Start new     |
  |                      (for cycle)   |
  |                                    |
  |         New session reads handoff  |
  |         Resumes work               |

## Who Manages Whom

| Agent | Sends lifecycle request to |
|-------|---------------------------|
| Polecat | <rig>/witness |
| Refinery | <rig>/witness |
| Witness | daemon/ |
| Mayor | daemon/ |

## Implementation

1. Detect current role (polecat, witness, refinery, mayor, crew)
2. Apply context-aware default if no flag specified
3. Run pre-flight checks (git clean, work handed off)
4. Send handoff mail to self (if cycling)
5. Send lifecycle request to appropriate manager
6. Set requesting_<action> in state.json
7. Wait (manager will kill us)

## For Polecats (--shutdown)

Additional cleanup after kill:
- Witness removes worktree
- Witness deletes polecat branch
- Polecat ceases to exist

## Related Issues

- gt-99m: Daemon (handles Mayor/Witness lifecycle)
- gt-7ik: Ephemeral polecats (polecat cleanup)
- gt-eu9: Witness session cycling


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

Clarify Mayor vs Witness cleanup responsibilities

Document the cleanup authority model: Witness owns ALL per-worker cleanup, Mayor never involved.

## The Rule

**Witness handles ALL per-worker cleanup. Mayor is never involved.**

## Why This Matters

1. Separation of concerns: Mayor strategic, Witness operational
2. Reduced coordination overhead: No back-and-forth for routine cleanup
3. Faster shutdown: Witness kills workers immediately upon verification
4. Cleaner escalation: Mayor only hears about problems

## What Witness Handles

- Verifying worker git state before kill
- Nudging workers to fix dirty state
- Killing worker sessions
- Updating worker state (sleep/wake)
- Logging verification results

## What Mayor Handles

- Receiving swarm complete notifications
- Deciding whether to start new swarms
- Handling escalations (stuck workers after 3 retries)
- Cross-rig coordination

## Escalation Path

Worker stuck -> Witness nudges (up to 3x) -> Witness escalates to Mayor -> Mayor decides: force kill, reassign, or human

## Anti-Patterns

DO NOT: Mayor asks Witness if worker X is clean
DO: Witness reports swarm complete, all workers verified

DO NOT: Mayor kills worker sessions directly
DO: Mayor tells Witness to abort swarm, Witness handles cleanup

DO NOT: Workers report done to Mayor
DO: Workers report to Witness, Witness aggregates and reports up


gt spawn: polecats report success but no work actually happens

## Problem

gt spawn polecats have multiple silent failure modes:

### Failure Mode 1: No gt prime
- Claude starts at prompt and waits for input
- SessionStart hook doesn't auto-run 'gt prime'
- Without gt prime, polecats don't pick up work

### Failure Mode 2: No git push (CRITICAL)
- Polecat commits code locally
- Polecat closes the beads issue
- Polecat sends POLECAT_DONE
- **But code is never pushed to remote branch**
- When worktree is cleaned up, commits are lost forever
- Issue appears closed but no code exists

## Evidence

testcat on bd-d28c:
- Reported 'Work Complete' with commits 7d3447b9, cd87e541
- Closed bd-d28c
- Submitted MR bd-yx22
- But: `grep -r 'TestCreateTombstone' cmd/bd/*.go` returns nothing
- No polecat/testcat branch on remote

## Required Fixes

1. Polecats MUST push their branch before closing issues
2. Witness MUST verify branch exists on remote before cleanup
3. gt spawn should auto-nudge 'gt prime'
4. Consider: Polecat handoff should fail if unpushed commits exist

## Verification Protocol for Witness

Before accepting POLECAT_DONE:
```bash
# 1. Verify branch pushed
git branch -r | grep polecat/<name>

# 2. Verify code exists
grep -r '<expected_function>' path/to/files

# 3. Only then cleanup
```


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]
```

Ephemeral patrol molecules leaking into beads

## Problem

Ephemeral patrol orchestration molecules (e.g., mol-deacon-patrol, wisp step issues) keep appearing in bd ready output in gastown beads.

These are ephemeral/wisp issues that should:
1. Never be synced to the beads-sync branch
2. Live only in .beads-wisp/ (ephemeral storage)
3. Be squashed to digests, not persisted as regular beads

## Examples found

- gt-wisp-6ue: mol-deacon-patrol
- gt-pacdm: mol-deacon-patrol
- gt-wisp-mpm: Check own context limit
- gt-wisp-lkc: Clean dead sessions

## Investigation needed

1. Where are these being created? (gt mol bond? manual bd create?)
2. Why are they using the gt- prefix instead of staying ephemeral?
3. Is the wisp storage (.beads-wisp/) being used correctly?
4. Is bd sync accidentally picking up ephemeral issues?

## Expected behavior

Patrol molecules and their steps should be ephemeral and never appear in bd ready or bd list.

Moved from bd-exy3.

Refinery needs branch visibility: Convert to worktree or push branches

The refinery cannot see polecat branches because it is a separate clone, not a worktree.

## Problem
- Polecats are worktrees of mayor/rig (correct, per gt-4u5z)
- Refinery is still a separate clone at refinery/rig (not converted)
- Polecat branches are local to mayor/rig, invisible to refinery

## Decision (2025-12-25)
**Use a shared bare repo as the single git source of truth.**

```
gastown/
├── .repo.git/           ← Bare repo (no working tree, invisible base)
├── mayor/rig/           ← Worktree (human workspace)
├── polecats/
│   └── Toast/           ← Worktree on polecat/Toast
├── refinery/rig/        ← Worktree on main (can see all branches!)
└── crew/max/            ← Worktree or separate clone (TBD)
```

**Why bare repo:**
- No working directory to accidentally work in
- Standard git pattern (how servers work)
- All worktrees share branch visibility
- Refinery on main can merge polecat branches directly

## Implementation
1. Create `.repo.git` as bare clone
2. Convert refinery to worktree of .repo.git on main
3. Convert polecats to worktrees of .repo.git
4. Optionally convert mayor/rig (or keep as worktree)
5. Update gt rig init for new rigs
6. Write migration for existing rigs

## Evidence
Tracer bullet 2025-12-23: Refinery could not see polecat/tracer until pushed to origin.

Witness cleanup should know worktree parent repo

Witness had to discover that polecat worktrees are created from mayor/rig, not the rig root.

## Problem
When cleaning up polecat/tracer:
- Witness ran git worktree remove from gastown/ - failed
- Had to discover worktree was from mayor/rig
- Then removed correctly

## Improvement
Witness should know the worktree parent repo path (mayor/rig) and clean up from there directly.

## Evidence
Tracer bullet 2025-12-23: Witness took extra steps to figure out cleanup path.

Fixed: Witness template now uses gt polecat nuke instead of raw git worktree commands. This command knows the correct worktree parent repo and handles cleanup properly.


Optimize: Share stepMap across control flow operators

In ApplyControlFlow, both ApplyBranches and ApplyGates call buildStepMap() separately:

```go
func ApplyBranches(steps []*Step, compose *ComposeRules) ([]*Step, error) {
    stepMap := buildStepMap(steps)  // Called here
    ...
}

func ApplyGates(steps []*Step, compose *ComposeRules) ([]*Step, error) {
    stepMap := buildStepMap(steps)  // Called again here
    ...
}
```

This is inefficient for large formulas. Options:

1. Pass stepMap as a parameter to ApplyBranches/ApplyGates
2. Create an internal version that accepts stepMap, keep public API unchanged
3. Build once in ApplyControlFlow and pass down

Low priority since formula sizes are typically small.

End-to-end test of the gate workflow.

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

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

## Moved from beads

Add keyboard navigation and filtering

Keyboard navigation: j/k or arrows to move, enter to expand/collapse, q to quit. Filtering: by rig name, worker name, event type. Search within activity stream.


Witness patrol: Add banners and wisp-based execution

Bring Witness patrol up to Deacon's level of sophistication:

## Current state
- mol-witness-patrol exists (gt-qflq)
- Basic step definitions

## Needed
1. **Banners** - Print step banners like Deacon does:
   ```
   ═══════════════════════════════════════════════════════════════
     👁 POLECAT-SCAN
     Checking polecat health and nudging stale workers
   ═══════════════════════════════════════════════════════════════
   ```

2. **Wisp-based execution** - Spawn patrol as wisp, squash when complete
3. **Handoff bead attachment** - Witness needs its own handoff bead with attached_molecule
4. **Loop-or-exit step** - Context-aware cycling like Deacon
5. **Patrol summary banner** at end of each cycle

## Reference
See Deacon patrol implementation in ~/gt/deacon/CLAUDE.md


bd ready --blockers: prioritize issues that block other work

bd ready should prioritize issues that are blocking other work.

**From VC**: Blocker-first prioritization in GetReadyWork(). ~100 lines.
Algorithm: baseline-failure first, then discovered:blocker, then by priority.

**Gas Town implementation**: CLI flag or default behavior:
```bash
bd ready --blockers-first  # Or make this default
```

Checks dependency graph. Issues with many dependents surface first.

**Value**: Unblocks parallelism faster. Critical path gets cleared.

**VC lesson**: Without blocker priority, work can starve on discovered issues.


Deacon patrol banners: visual feedback on atom transitions

Print large ASCII banners when transitioning between patrol atoms.

## Problem

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

## Desired Behavior

Print banners on step start and completion:

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

## Benefits

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

## Implementation Options

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

Day 2.7a: gt install creates Deacon and Mayor agent beads

Update gt install to create agent beads:

   - gt-deacon agent bead (role_type: deacon, rig: null, agent_state: idle)
   - gt-mayor agent bead (role_type: mayor, rig: null, agent_state: idle)

2. Use bd create --type=agent or internal beads API

Files:
- internal/cmd/install.go

Moved to gt rig add instead of gt install due to routing constraints. Agent beads need to be in rig beads (not town beads) for daemon to find them via prefix routing. First rig added gets gt-deacon and gt-mayor.

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 errors instead:
```go
RunE: func(cmd *cobra.Command, args []string) error {
    ...
    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

Patrol hygiene: Witness/Refinery/Deacon inbox cleanup

## Summary
Patrol roles should clean up their inboxes as part of normal operation, not let messages accumulate.

## Witness Patrol Cleanup
- POLECAT_STARTED: archive after acknowledging
- POLECAT_DONE: archive after cleanup complete
- LIFECYCLE requests: archive after processing
- Keep only: active work, unprocessed requests

## Refinery Patrol Cleanup
- MR Ready: archive after merge/reject decision
- Swarm notices: archive after dispatch
- Keep only: pending MRs in queue

## Deacon Patrol Cleanup
- Rotate daemon.log when >10MB
- Prune state.json of dead sessions
- Archive old daemon logs (gzip, date-suffix)

## Implementation
Each patrol molecule should have a 'cleanup' phase at end of cycle.

## Related

Merge Queue in Beads: Universal chit system for all work

**Design doc**: docs/merge-queue-design.md


MR field parsing: extract structured fields from description

Parse merge-request beads to extract structured fields:
- branch: source branch name
- target: target branch (main or integration/xxx)
- source_issue: the work item being merged
- worker: who did the work
- rig: which rig
- merge_commit: (set on close)
- close_reason: (set on close)

Fields stored in description as YAML block or key: value lines.
Provide helper functions: ParseMRFields(issue) and SetMRFields(issue, fields).

Reference: docs/merge-queue-design.md#merge-request-schema


Auto-rebase on conflict: optional automatic rebase

Implement automatic rebase as conflict resolution option.

When on_conflict=auto_rebase and conflicts detected:
1. Attempt: git rebase <target> <source-branch>
2. If clean rebase: update source branch, continue merge
3. If conflicts in rebase: abort, fall back to assign_back
4. Force push rebased branch (worker's branch)

Requires:
- Worker branch must be force-pushable
- Config: on_conflict: auto_rebase

Risks:
- Force push can confuse workers
- Complex conflicts still need manual resolution

Reference: docs/merge-queue-design.md#conflict-resolution-strategies


Retry logic: exponential backoff for transient failures

Implement retry logic for transient failures.

Retryable failures:
- Push failed (network, auth transient)
- Test flaky (config: retry_flaky_tests)
- Fetch failed (network)

Retry strategy:
- Max retries: 3 (configurable)
- Backoff: 1s, 2s, 4s (exponential)
- On final failure: treat as permanent, assign back

Non-retryable failures:
- Merge conflict
- Test consistently fails
- Build error

Track retry count in MR metadata for debugging.

Reference: docs/merge-queue-design.md#failure-recovery


MQ metrics: pending count, processing time, success rate

Implement merge queue metrics collection.

Metrics to track:
- mq_pending_count: MRs waiting
- mq_processing_time: Time from submit to merge (histogram)
- mq_success_rate: Merges vs rejections
- mq_conflict_rate: How often conflicts occur
- mq_test_failure_rate: Test failures

Storage options:
- Simple: JSON file with rolling stats
- Advanced: Prometheus-compatible metrics endpoint

Display via:
- gt mq stats: summary statistics
- Dashboard widget (separate task)

Reference: docs/merge-queue-design.md#observability


MQ dashboard widget: queue status in TUI

Add merge queue status widget to the Bubbletea TUI dashboard.

Display:
┌─────────────────────────────────────────────────┐
│              MERGE QUEUE STATUS                  │

Direct landing integration: gt land uses MR or bypasses

Integrate direct landing with merge queue.

'gt land --direct' should:
1. Check if MR exists for the polecat's work
2. If MR exists: process it directly (skip queue)
3. If no MR: create temporary MR, process, close

Options:
- --direct: bypass queue (existing)
- --via-queue: ensure goes through queue (new)
- --force: skip safety checks (existing)

This ensures direct landing still creates proper records.

Reference: docs/merge-queue-design.md#direct-landing-bypass-queue


Rollback support: gt mq revert for problematic merges

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

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

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

Track revert in MR metadata for audit trail.

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


MR ID generation: prefix-mr-hash convention

Generate merge-request IDs following the convention: <prefix>-mr-<hash>

Example: gt-mr-abc123 for a gastown merge request.

This distinguishes MRs from regular issues while keeping them in the same namespace.
The hash should be derived from branch name + timestamp for uniqueness.

Implement: GenerateMRID(prefix, branch string) string

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


MR state transitions: validate open→in_progress→closed

Enforce valid state transitions for merge-requests:

Valid transitions:
- open → in_progress (Engineer claims MR)
- in_progress → closed (merge success or rejection)
- in_progress → open (failure, reassign to worker)
- open → closed (manual rejection)

Invalid:
- closed → anything (immutable once closed)

Implement validation in MR update operations.

Reference: docs/merge-queue-design.md#state-machine


gt mq integration create: create integration branch for epic

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

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

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

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

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


gt mq integration land: merge integration branch to main

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

Actions:
1. Verify all MRs targeting integration/<epic> are merged
2. Verify integration branch exists
3. Merge integration/<epic> to main (--no-ff)
4. Run tests on main
5. Push to origin
6. Delete integration branch
7. Update epic status

Options:
- --force: land even if some MRs still open
- --skip-tests: skip test run
- --dry-run: preview only

This creates a single merge commit for the entire epic's work.

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


gt mq integration status: show integration branch status

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

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

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

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

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

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


Auto-target: MRs for epic children target integration branch

Automatically target integration branches for epic children.

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

This ensures batch work automatically flows to integration branches.

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

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


MQ config schema: merge_queue section in rig config.json

Define and implement merge_queue configuration in rig config.

Schema:
{
  "merge_queue": {
    "enabled": true,
    "target_branch": "main",
    "integration_branches": true,
    "on_conflict": "assign_back",  // or "auto_rebase"
    "run_tests": true,
    "test_command": "go test ./...",
    "delete_merged_branches": true,
    "retry_flaky_tests": 1,
    "poll_interval": "30s",
    "max_concurrent": 1
  }
}

Implement:
- Config loading in rig package
- Default values
- Validation

Reference: docs/merge-queue-design.md#configuration


Per-epic config overrides: custom merge settings

Allow per-epic merge configuration overrides.

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

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

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

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


Day 1.3: Implement bd slot set/clear commands

Add slot management commands:
- bd slot set <agent> <slot> <bead> - set slot (error if occupied)
- bd slot clear <agent> <slot> - clear slot
- bd slot show <agent> - show all slots

These enforce cardinality constraints.

CODE REVIEW (valkyrie): REQUEST CHANGES

Critical bugs found in internal/swarm/manager.go:
1. JSON field changed from 'dependents' to 'dependencies' but bd outputs 'dependents'
2. 'hooked' status removed from in_progress handling
3. Assignee field removed from task loading

These changes will break swarm coordination. Polecat_spawn.go fix is correct.

Recommendation: Revert swarm/manager.go changes, keep polecat_spawn.go fix.

REJECTED: Critical bugs in swarm/manager.go must be fixed. See notes for details. The polecat_spawn.go fix is correct but swarm changes break JSON parsing (dependents vs dependencies mismatch) and remove hooked status handling.


gt rig add: Auto-configure HQ routes.jsonl for new rigs

## Summary

When `gt rig add <rig-name>` adds a new rig to the town, it should automatically
add a routing entry to `~/gt/.beads/routes.jsonl` so that beads with that rig's
prefix can be looked up from the town root.

## Current Behavior

After running `gt rig add myproject`:
- Rig is cloned and set up
- No routing entry is added to HQ beads

## Desired Behavior

After running `gt rig add myproject`:
- Rig is cloned and set up
- Detect the rig's beads prefix (from config.yaml or existing issues)
- Add entry to `~/gt/.beads/routes.jsonl`:
  `{"prefix": "mp-", "path": "myproject/mayor/rig"}`

## Implementation Notes

1. After rig setup, check for `<rig>/mayor/rig/.beads/config.yaml`
2. Read `issue-prefix` if set, or sample an issue ID from the database
3. Append to `~/gt/.beads/routes.jsonl` if the prefix isn't already routed
4. Create routes.jsonl if it doesn't exist

## Edge Cases

- Rig has no beads yet (no prefix known) - skip routing setup, let doctor fix later
- Prefix already exists in routes.jsonl - warn and skip (or update path?)
- routes.jsonl doesn't exist - create it


Pinned beads architecture implementation

Implement the pinned beads architecture from docs/pinned-beads-design.md

Phases:
1. Doctor checks for hook validation
2. Dashboard visibility (gt hooks, gt dashboard)
3. Protocol enforcement (self-pin, audit trail)
4. Documentation updates


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
Fix suggestion: Delete duplicate(s) with bd close


Add hook-attachment-valid doctor check

Add gt doctor check to verify attached molecules exist and are not closed.

Check: hook-attachment-valid
Error if: Hook's attached_molecule field points to non-existent or closed issue
Fix suggestion: Clear attachment with gt mol detach


Add orphaned-attachments doctor check

Add gt doctor check for molecules attached to non-existent agents.

Check: orphaned-attachments
Warning if: Handoff bead exists for agent that no longer has worktree
Fix suggestion: Re-sling to active agent or close molecule


Add stale-attachments doctor check

Add gt doctor check for work stale on hook without progress.

Check: stale-attachments
Warning if: Attached molecule has no activity for >24h
Suggestion: Check agent status, consider nudge or reassignment


Implement gt hooks command

New command to show all hooks across a rig.

Usage: gt hooks [rig]

Output shows:
- All polecats and their hook status
- Witness hook status
- Refinery hook status
- Crew member hook status
- Progress bars for attached molecules


Add hook status to gt status output

Enhance gt status to show hook summary for each rig.

Current: Shows rig list and basic counts
New: Also shows occupied hooks count and any stale attachments


Implement gt mol attach-from-mail command

Allow agents to self-pin work from mail.

Usage: gt mol attach-from-mail <mail-id>

Behavior:
1. Read mail body for attached_molecule field
2. Attach molecule to agent's hook
3. Mark mail as read
4. Return control for execution

Handles case where work was sent via mail but not slung to hook.


Add audit trail for hook detach operations

Log detachment events for debugging and monitoring.

When work is detached from hook:
- Log timestamp, agent, molecule ID, reason
- If abnormal (not completion), notify Witness
- Consider adding to wisp digest for patrol cycles


Update role prompts with hook protocol

Update role prompt templates to include hook-first protocol.

Templates to update:
- polecat.md.tmpl
- deacon.md.tmpl
- witness.md.tmpl
- refinery.md.tmpl
- crew.md.tmpl

Each should include:
1. Check hook first (gt mol status)
2. If empty, check mail for attached work
3. Self-pin protocol if needed

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).

P7: escalation for mayor (wrong-rig work)


Audit hardcoded 'gastown' references in codebase

## Problem

Gas Town should work for ANY rig - not assume 'gastown' (our OSS project) is installed. Found during audit:

### Known Issue (Closed - gt-ci84)
- Deacon patrol wisps were incorrectly using `gastown/mayor/rig/.beads/` instead of town-level beads
- Status: Fixed (implemented town-level wisp storage)

### Remaining Issues

1. **log.go:272** - Fallback path heuristic:
   ```go
   possibleRoots := []string{
       home + "/gt",
       home + "/gastown",  // <-- Assumes user might have gastown as town
   }
   ```
   Should be removed or use a config-based approach.

2. **Help text examples** - Many commands use 'gastown' as the example rig:
   - `gt sling gt-abc gastown`
   - `gt witness start gastown`
   - etc.
   Consider using a generic name like 'myproject' or '<rig>'

3. **Polecat name pool** - 'gastown' is in the Mad Max themed name list.
   This is acceptable (just a name, not a path assumption).

## Tasks
1. Remove `home + "/gastown"` fallback from log.go
2. Consider updating help examples to use generic rig names
3. Full code audit to ensure no other hardcoded assumptions

## Context
Gas Town is the orchestration framework. 'gastown' is just our OSS project that happens to use it. Users installing Gas Town for their own projects should never see anything that assumes 'gastown' rig exists.

gt polecat remove --all: bulk polecat teardown

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

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

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

Track merge requests as beads (type=merge-request)

Currently MRs are tracked in .gastown/refinery.json. For HOP audit trail and entity CV tracking, merge requests should be Beads entries with type=merge-request. This enables:
- Full audit trail of what was merged, when, by whom
- Entity chain contributions (who validated what)
- Cross-rig visibility of merge activity

The refinery would create an MR bead when work enters the queue, update status as it progresses (open → in_progress → merged/rejected).

Add to internal/mail/types.go:
```go
type MessageType string
const (
    TypeTask         MessageType = "task"         // Required processing
    TypeScavenge     MessageType = "scavenge"     // Optional first-come work
    TypeNotification MessageType = "notification" // Informational
    TypeReply        MessageType = "reply"        // Response to message
)

// Update Message struct
type Message struct {
    // existing fields...
    Type     MessageType `json:"type"`
    ThreadID string      `json:"thread_id,omitempty"`
    ReplyTo  string      `json:"reply_to,omitempty"`
}
```

## 2. Priority Levels
Expand from 2 to 4:
```go
type Priority string
const (
    PriorityLow    Priority = "low"
    PriorityNormal Priority = "normal"
    PriorityHigh   Priority = "high"
    PriorityUrgent Priority = "urgent"
)
```

## 3. CLI Updates
internal/cmd/mail.go:
- Add --type flag to send: `gt mail send ... --type task`
- Add --reply-to flag: `gt mail send ... --reply-to <msg-id>`
- Add thread command: `gt mail thread <thread-id>`

## 4. Threading Logic
NewMessage() should auto-generate thread_id if not a reply.
Reply messages inherit thread_id from original.

## Files to Modify
- internal/mail/types.go: Add types, expand Priority
- internal/mail/mailbox.go: Thread filtering
- internal/cmd/mail.go: CLI flags and thread command

## PGT Reference
gastown-py/src/gastown/mail/message.py

## Acceptance Criteria
- [ ] Messages have type field (default: notification)
- [ ] 4 priority levels supported
- [ ] Reply creates thread with shared thread_id
- [ ] gt mail thread <id> shows conversation


Polecat writes files outside worktree (integration test)

During integration test gt-7psb8, polecat furiosa was asked to create ~/gt/gastown/test-polecat-integration.txt

It used Write tool with relative path '../../test-polecat-integration.txt' which resolved to gastown root instead of its worktree at ~/gt/gastown/polecats/furiosa/

Observed:
- File created at ~/gt/gastown/test-polecat-integration.txt (WRONG)
- Furiosa worktree at ~/gt/gastown/polecats/furiosa/ has no such file
- Furiosa branch has no commits of any new files

Root cause: Claude Code resolves relative paths from cwd, and the polecat may have been in the wrong directory or used incorrect path.

This caused the entire merge to be empty (branch at same commit as main).

Remove pinned field workaround after beads fix

## Summary

Once bd-phtv is fixed in beads, we can remove the workaround documentation and potentially simplify the pinToHook() implementation.

## Current Workaround

The handoff bead attachment mechanism (AttachMolecule) is used as the primary work assignment mechanism instead of the pinned field. This works correctly but adds complexity.

## Changes After Beads Fix

1. Remove the NOTE comment in internal/beads/beads.go:Pin() explaining the bug
2. Consider simplifying pinToHook() if the pinned field becomes reliable
3. Update gt-o3is to reference the fix

## Blocked By

This issue is blocked by external:beads:pinned-field-fix (bd-phtv).
When that capability is shipped, this issue becomes ready.

## Related

- gt-o3is: Original investigation that found this bug
- bd-phtv: The beads fix (in ~/gt/beads)

BLOCKED: Can't add external:beads:pinned-field-fix dependency due to bd-ucgz (migration invariants bug). Once that's fixed, add: bd dep add gt-hj9e external:beads:pinned-field-fix

Day 1.7: Define per-rig agent bead ID pattern

Document and implement the agent bead ID pattern for per-rig agents.

Pattern: gt-<role>-<rig>
Examples:
- gt-witness-gastown
- gt-refinery-gastown
- gt-refinery-beads
- gt-polecat-gastown-nux

Town-level agents (no rig):
- gt-mayor
- gt-deacon

This pattern enables:
- Consistent lookup: bd show gt-witness-gastown
- Routing: routes.jsonl maps prefixes
- Filtering: bd list --type=agent --rig=gastown

Update:

Add merge queue observability

## Problem

The per-rig merge queue (refinery) lacks visibility into its operational state.
Operators can't easily tell:
- When the queue is backing up (items waiting)
- When it's empty/idle
- Queue depth over time
- Processing rate

## Requirements

- Surface queue depth (pending items count)
- Show current processing state (idle, processing, blocked)
- Indicate when queue is backing up (growing faster than draining)
- Make this accessible via `gt status` or similar command

## Possible Approaches

1. Add queue stats to `gt status` output
2. Create dedicated `gt mq status` command
3. Emit metrics/events that can be consumed
4. Add to witness monitoring scope

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)

Heartbeat convention: simple liveness signal for agents

Lightweight liveness signal extracted from Deacon epic (gt-5af).

**Implementation**: Each agent writes a timestamp file on activity:
```bash
echo '{"ts":"'$(date -Iseconds)'"}' > ~/gt/<role>/heartbeat.json
```

**Integration points**:
- SessionStart hook writes heartbeat
- Periodic activity (mail check, work completion) refreshes it
- `gt status` shows staleness (e.g., 'mayor: 5m ago')

**Weight**: ~5 lines per agent
**Value**: Quick debugging - see which agents are active at a glance

No monitoring daemon needed - human checks `gt status` when curious.

GGT Command Parity: Complete gt command coverage

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

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


Fix potential race conditions in state file operations

Non-atomic state file operations could cause data loss:

All packages with state files (witness, refinery, crew, swarm):
State is loaded, modified, and saved without locking:
  ref, err := m.loadState()
  // ... modify ref ...
  return m.saveState(ref)

If two processes modify state simultaneously, one update may be lost.

internal/polecat/namepool.go (lines 179-194):
Save() uses RLock() but performs file I/O - should use write lock.

internal/swarm/manager.go:
swarms map[string]*Swarm accessed without mutex but multiple goroutines could call Create/GetSwarm.

Suggestion:
1. Use file locking (flock) for critical state updates
2. Or use atomic write pattern (write to temp, then rename)
3. Add mutex to swarm.Manager.swarms map


Pillar 2: Patrol Ignition

Witness and Refinery patrol loops fire reliably.

Key deliverables:
- Witness patrol reads agent beads for polecat state
- Witness sends MERGE_READY to refinery on completion
- Refinery processes MERGE_READY mail
- Both send completion signals

Subsumes existing work:
- gt-6qyt1: Refinery event-driven merge queue
- gt-qpwv4: Witness detect completion
- gt-dtw9u: Witness active monitoring

Crew agent beads never created (dead code in reportAgentState)

## Problem

In prime.go, reportAgentState is called for ALL roles including crew workers.
The function calls bd.UpdateAgentState for crew with ID like gt-crew-gastown-max.

But crew agent beads are NEVER created:
- Polecats: Created on spawn (polecat/manager.go:167)
- Infrastructure: Created by doctor/install (doctor/agent_beads_check.go)
- Crew: Nothing creates them

The error is silently ignored, so this doesn't break anything, but it's dead code.

## Found in commit

f3a6ef6 (feat: Witness reads polecat state from agent beads)

## Decision

**Create crew agent beads** on first gt prime if they don't exist.

Crew workers are human-managed but their state is still valuable for:
- Town-wide status dashboards
- Understanding who's working on what
- Consistent agent bead model across all agent types

## Implementation

In prime.go reportAgentState(), before calling UpdateAgentState:
1. Try to get the agent bead
2. If it doesn't exist, create it with CreateAgentBead
3. Then update state as normal

     "cleanup/gastown": ["gastown/witness", "deacon/"]

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.

Polecat sessions terminate unexpectedly during work

During swarm bd-784c, polecat sessions (Toast, Nux) terminated mid-task without completing their work.

**Observed:**
- Polecats were actively working (edits in progress, tests running)
- Sessions suddenly showed 'not running' in gt polecat status
- tmux sessions existed but were empty/reset
- Work was partially complete (some commits made, issue still open)

**Impact:**
- Lost work progress
- Required manual intervention to restart
- Unclear if work was saved/committed

**Suggestion:**
- Add session health monitoring
- Auto-restart on unexpected termination
- Log session exit reasons

Implemented session health monitoring and auto-restart for crashed polecats. Changes include: (1) daemon now proactively checks polecat session health and auto-restarts crashed sessions with work-on-hook, (2) added polecat support to lifecycle identity mapping, (3) added 'gt session check' command for manual health checking.


Add tmux crash detection hooks

Use tmux hooks to detect when agent panes die unexpectedly.

## tmux Hooks to Use
- pane-died: fires when a pane exits
- session-closed: fires when session ends

## Implementation
```bash
set-hook -g pane-died 'run-shell "gt log pane-died #{pane_id} #{pane_dead_status}"'
set-hook -g session-closed 'run-shell "gt log session-closed #{session_name}"'
```

## Integration
- gt spawn should set these hooks on agent sessions
- Distinguish expected exits (handoff, done) from crashes
- Capture last N lines of output on crash
- Record exit code/signal for forensics

## gt log crash command
- Parse pane-died events
- Show crash history
- Filter by agent, time range

crew_add.go: Agent bead ID uses wrong format

In internal/cmd/crew_add.go:84, the agent bead ID is constructed as:

This produces 'gt-crew-gastown-joe' but existing beads and the session name format use:

  gt-<rig>-crew-<name>  (e.g., gt-gastown-crew-joe)

This causes agent beads to not be found/matched properly.

Fix: Change line 84 to:

  crewID := fmt.Sprintf("gt-%s-crew-%s", rigName, name)

Already fixed by max in c31bff4 - now uses beads.CrewBeadIDWithPrefix()

Deacon Kernel: event processing molecule architecture

Extend the Deacon from "health orchestrator" to "event processing kernel" that runs a
molecule (rounds) each wake cycle, like an OS kernel scheduler.

## Core Insight

The Deacon already has:
- Wake cycle (daemon poke, timer, lifecycle request)
- Mail as event queue
- Health scanning
- Lifecycle processing

But it is REACTIVE. This epic makes it PROACTIVE with a structured molecule:

```
Deacon Wake
├── Step 0: Session Check (should I cycle myself?)
├── Step 1: Health Scan (Mayor, Witnesses, Crew, Refineries)
├── Step 2: Lifecycle Processing (cycle/restart/shutdown requests)
├── Step 3: Plugin Execution (scheduled, event-triggered, human-requested)
├── Step 4: Event Callbacks (timers, subscriptions)
└── Step 5: Heartbeat + Wait
```

## Key Design Decisions

1. **Session cycling first** - Token costs are quadratic with session length.
   Deacon should aggressively cycle to fresh sessions. First step of every
   wake is "do I need a new session?" based on context budget.

2. **Pinned bead with marching orders** - A pinned bead (like gt prime for
   agents) defines the Deacon's rounds molecule. This is the Deacon's
   "kernel" - its operating loop.

3. **Keepalive file for daemon quieting** - Instead of daemon tmux-poking
   the Deacon (which interrupts work), Deacon writes a keepalive file.
   Daemon reads it and backs off. Worst case: Deacon forgets, gets one
   extra heartbeat it squelches.

4. **Molecule-based rounds** - The wake cycle becomes a molecule with steps.
   Each step can have plugins (inline attention). Steps can be added/modified
   by updating the pinned bead.

## Architecture

```
Go Daemon (minimal, dumb)
├── Reads {townRoot}/deacon/keepalive.json
├── If fresh: do nothing
├── If stale: poke Deacon (fallback)
└── Process lifecycle requests (still daemon's job)

Deacon (Claude agent, smart)
├── Wakes: poke, timer, mail event
├── Writes keepalive (quiets daemon for duration of rounds)
├── Runs rounds molecule:
│   ├── session-check: cycle if context budget low
│   ├── health-scan: check agents, remediate
│   ├── lifecycle: process requests
│   ├── plugins: run scheduled/triggered plugins
│   ├── events: process timer/event callbacks
│   └── complete: update heartbeat, wait
└── Reads marching orders from pinned bead
```

## Relation to Existing Work

- Extends gt-5af (Deacon infrastructure) - CLOSED
- Relates to gt-axz (Plugin architecture) - P3
- Fits into phase3-deacon of gt-ngpz (Christmas Plan)
- Enables gt-976 (Crew lifecycle) as part of health-scan step


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.


Deacon marching orders: pinned bead with rounds molecule

Create a pinned bead that defines the Deacon's rounds molecule - its "kernel".

## Concept

Like `gt prime` gives agents their context, a pinned bead gives the Deacon
its operating instructions. This bead defines:

1. The rounds molecule (steps to execute each wake)
2. Registered plugins (scheduled, event-triggered)
3. Configuration (timeouts, thresholds, escalation rules)

## Pinned Bead Structure

```yaml
# gt-deacon-kernel (pinned)
title: "Deacon Kernel Configuration"
type: policy
pinned: true

molecule: mol-deacon-rounds
  steps:
    - session-check: "Check context budget, cycle if needed"
    - health-scan: "Check Mayor, Witnesses, Refineries, Crew"
    - lifecycle: "Process pending lifecycle requests"
    - plugins: "Run due scheduled plugins"
    - events: "Process timer callbacks, event subscriptions"
    - complete: "Update heartbeat, return to wait"

plugins:
  scheduled:
    - name: beads-hygiene
      schedule: "0 2 * * *"  # 2 AM daily
    - name: branch-cleanup
      schedule: "0 4 * * 0"  # 4 AM Sundays

  event_triggers:
    - event: "issue.created"
      plugin: work-oracle
    - event: "mr.submitted"
      plugin: review-oracle

config:
  session_cycle_threshold_turns: 50
  session_cycle_threshold_hours: 4
  health_scan_timeout_seconds: 60
  plugin_timeout_minutes: 30
  escalation_after_failures: 3
```

## Reading Marching Orders

On wake, Deacon:
1. `bd show --pinned` to find the kernel bead
2. Parse molecule steps
3. Execute in order

## Updating the Kernel

To change Deacon behavior:
1. `bd update gt-deacon-kernel` with new config
2. Next wake cycle picks up changes
3. No code changes required

## Bootstrap

If no pinned bead exists, Deacon uses hardcoded defaults from DEACON.md.
First installation creates the pinned bead.


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
```


Deacon rounds molecule: the kernel execution loop

Define and implement mol-deacon-rounds - the molecule the Deacon executes each wake.

## Molecule Definition

```markdown
# mol-deacon-rounds

The Deacon kernel - executed on every wake cycle.

## Step: session-check
Check context budget. If low, cycle to fresh session.
Needs: (none - always runs first)

## Step: health-scan
Check health of all monitored agents:
- Mayor (gt-mayor session)
- Witnesses (gt-*-witness sessions)
- Refineries (gt-*-refinery sessions)
- Crew (gt-*-* sessions, lifecycle only)

Remediate unhealthy agents:
- Restart dead sessions
- Nudge stuck agents
- Escalate if remediation fails

Needs: session-check

## Step: lifecycle
Process pending lifecycle requests from mail:
- LIFECYCLE: <identity> requesting cycle
- LIFECYCLE: <identity> requesting restart
- LIFECYCLE: <identity> requesting shutdown

Needs: health-scan

## Step: plugins
Run due plugins:
1. Check scheduled plugins (cron-like)
2. Check event-triggered plugins (from mail events)
3. Check human-requested plugins (from mail)
4. Execute each, record outcomes

Needs: lifecycle

## Step: events
Process timer and event callbacks:
- TIMER: <identity> wake at <time>
- EVENT: <type> <payload>

Notify relevant agents or trigger actions.

Needs: plugins

## Step: complete
Finalize the cycle:
1. Update heartbeat.json
2. Clear/update keepalive.json
3. Log summary
4. Return to prompt (wait for next wake)

Needs: events
```

## Execution

The Deacon reads this molecule from its pinned bead and executes steps in order.
Each step:
1. Announces "Starting <step>"
2. Performs the step logic
3. Records outcome
4. Proceeds to next step

## Step Plugins

Each step can have inline plugins (additional attention):
```yaml
step: health-scan
  plugins:
    - advanced-diagnostics  # Run if basic scan finds issues
```

## Relation to bd mol

Uses the same molecule format as bd mol for polecats.
Deacon molecule is special: it's the kernel, not work.


Deacon plugin scheduler: cron-like execution

Implement scheduled plugin execution in the Deacon's plugins step.

## Concept

Plugins are just directories with config. Deacon checks which are due
and executes them during the plugins step of rounds.

## Plugin Registration

Plugins are registered in:
1. Pinned kernel bead (preferred)
2. `{townRoot}/plugins/` directory scan (fallback)

Each plugin has:
```json
{
  "name": "beads-hygiene",
  "schedule": "0 2 * * *",
  "last_run": "2025-12-20T02:00:00Z",
  "enabled": true,
  "attention_budget": "low",
  "max_duration_minutes": 30
}
```

## Schedule Format

Standard cron format: `minute hour day month weekday`
- `0 2 * * *` - 2 AM daily
- `0 4 * * 0` - 4 AM Sundays
- `*/15 * * * *` - Every 15 minutes

## Execution

During plugins step:
1. Load plugin schedules from kernel bead + directory
2. For each plugin:
   a. Parse schedule, check if due (last_run + schedule)
   b. If due, execute:
      - Read `plugins/{name}/CLAUDE.md` for context
      - Run plugin logic (inline or spawn subagent)
      - Record outcome and update last_run
3. Continue to next step

## Plugin Execution Modes

- **inline**: Deacon runs the plugin logic directly (simple, fast)
- **subagent**: Spawn a polecat-like agent for the plugin (complex, parallel)
- **mail**: Send mail to another agent to do the work (delegation)

## State Tracking

`{townRoot}/deacon/plugin-state.json`:
```json
{
  "plugins": {
    "beads-hygiene": {
      "last_run": "2025-12-20T02:00:00Z",
      "last_outcome": "success",
      "run_count": 42,
      "failure_count": 2
    }
  }
}
```

## Relation to gt-axz

This implements the execution side of the plugin architecture (gt-axz).
gt-axz defines the format; this task implements the scheduler.


Deacon event/timer callbacks: reactive triggers

Implement event-triggered and timer-based callbacks in the Deacon.

## Timer Callbacks

Agents can schedule future wakes by mailing the Deacon:
```
Subject: TIMER: gastown/witness wake at 2025-12-20T16:00:00Z
Body: Please nudge me - I'm waiting for external dependency
```

Deacon processing:
1. Parse timer mail
2. Check if time has passed
3. If yes: mail the agent "WAKE: Timer fired"
4. Close the timer mail

## Event Subscriptions

Plugins/agents can subscribe to events:
```yaml
# In kernel bead or plugin config
event_triggers:
  - event: "issue.created"
    action: mail
    target: "plugins/work-oracle"

  - event: "mr.submitted"
    action: run
    plugin: "review-oracle"

  - event: "agent.stuck"
    action: escalate
    target: human
```

## Event Sources

Events come through mail to deacon/:
```
Subject: EVENT: issue.created gt-abc123
Body: New issue created in gastown rig
```

## Event Types

Initial event types:
- `issue.created` - New bead created
- `issue.closed` - Bead closed
- `mr.submitted` - Merge request submitted
- `mr.merged` - Merge request merged
- `agent.stuck` - Agent appears stuck (from health scan)
- `agent.failed` - Agent remediation failed

## Event Processing

During events step:
1. Read event mail from inbox
2. Match against subscriptions
3. Execute actions:
   - `mail`: Send mail to target
   - `run`: Execute plugin inline
   - `spawn`: Spawn subagent for plugin
   - `escalate`: Mail human

## Relation to Mail

Mail IS the event bus. No separate event system.
Events are just specially-formatted mail to deacon/.

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.

Patrol 8: All healthy


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

Fix bugs blocking Witness functionality:

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

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

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

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

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


Agent bead creation uses wrong prefix for non-gastown rigs

When adding a polecat to beads rig, agent bead creation fails:
  Error: issue ID 'gt-polecat-beads-Toast' does not match configured prefix 'bd'

The agent bead ID should use the rig's prefix (bd-) not hardcoded gt-.

Fixed: Added WithPrefix variants to agent bead ID functions, updated crew_add.go, rig/manager.go, and doctor/agent_beads_check.go to use rig's configured prefix


Formula SDK: Developer Tooling for Workflow Authors

SDK for creating, testing, debugging, and validating formulas.

## Components

### Forge (Creation)
```bash
mol forge new my-workflow        # Scaffold new formula
mol forge extend base-workflow   # Create variant
mol forge lint my-workflow       # Check syntax/style
```

### Lab (Testing)
```bash
mol lab run my-workflow --dry-run   # Mock execution
mol lab test my-workflow            # Run formula tests
mol lab trace my-workflow           # Step-through debug
```

### Validator (Verification)
```bash
mol validate my-workflow                    # Check well-formedness
mol validate my-workflow --protocol=Reviewable  # Check protocol compliance
mol validate my-workflow --schematic=shiny  # Check schematic compatibility
```

### Analyzer (Static Analysis)
```bash
mol analyze my-workflow --deps     # Dependency graph
mol analyze my-workflow --coverage # Step coverage
mol analyze my-workflow --cycles   # Detect cycles
```

## Relationship to Other Concepts

The SDK operates on:
- Formulas (source level)
- Protos (compiled level)
- Molecules (runtime level)

And validates against:
- Protocols (type system)
- Schematics (domain composition)

## Open Questions

1. Bundled vs separate - mol subcommands or formula-kit binary?
2. IDE integration - LSP for formula files?
3. Test harness - how to mock steps? fixtures?

Architecture: Decentralized rig structure with per-rig agents

## Decision

Adopt decentralized architecture where each rig contains all its agents (mayor/, witness/, refinery/, polecats/) rather than centralizing mayor clones at town level.

## Town Level Structure

```
~/ai/                              # Town root
├── config/                        # Town config (VISIBLE, not hidden)
│   ├── town.json                  # {"type": "town"}
│   ├── rigs.json                  # Registry of managed rigs
│   └── federation.json            # Wasteland config (future)
│
├── mayor/                         # Mayor's HOME at town level
│   ├── CLAUDE.md
│   ├── mail/inbox.jsonl
│   └── state.json
│
└── <rigs>/                        # Managed projects
```

## Rig Level Structure (e.g., wyvern)

```
wyvern/                            # Rig = clone of project repo
├── .git/info/exclude              # Gas Town adds: polecats/ refinery/ witness/ mayor/
├── .beads/                        # Beads (if project uses it)
├── [project files]                # Clean project code on main
│
├── polecats/                      # Worker clones
│   └── <name>/                    # Each is a git clone
│
├── refinery/
│   ├── rig/                       # Refinery's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
├── witness/                       # NEW: Per-rig pit boss
│   ├── rig/                       # Witness's clone
│   ├── state.json
│   └── mail/inbox.jsonl
│
└── mayor/
    ├── rig/                       # Mayor's clone for this rig
    └── state.json
```

## Key Decisions

1. **Visible config dir**: `config/` not `.gastown/` (models don't find hidden dirs)
2. **Witness per-rig**: Each rig has its own Witness (pit boss) with its own clone
3. **Mayor decentralized**: Mayor's clones live IN each rig at `<rig>/mayor/rig/`
4. **Minimal invasiveness**: Only `.git/info/exclude` modified, no commits to project
5. **Clone subdir name**: Keep `rig/` for consistency (refinery/rig/, witness/rig/, mayor/rig/)

## Role Detection

- Town root or mayor/ → Mayor (town level)
- Rig root → Mayor (canonical main)
- <rig>/mayor/rig/ → Mayor (rig-specific)
- <rig>/refinery/rig/ → Refinery
- <rig>/witness/rig/ → Witness
- <rig>/polecats/<name>/ → Polecat

## Migration from PGT

- `mayor/rigs/<rig>/` → `<rig>/mayor/rig/`
- `<rig>/town/` → eliminated (rig root IS the clone)
- Add `witness/` to each rig

Day 1.1: Add type=agent to bead schema

Add agent as a valid bead type in the schema. This is the foundation for agent-as-bead.

Parent: gt-d0jqp

Re-opened: Close reason referenced non-existent commit 927e8374. Type=agent not yet implemented in bd CLI.


bd update --claim for work queue semantics

Atomic claim operation for work queue messages.

## Deliverables

1. Add --claim flag to bd update
2. Atomic operation:
   - Sets assignee to claimer
   - Sets status to in_progress
   - Fails if already claimed
3. Conflict detection:
   - If already claimed, return error: "already claimed by X"
4. Integration with gt mail for queue messages

## Example
```bash
gt mail queue cleanup/gastown  # See available work
bd update msg-xxx --claim       # Claim it atomically
# Returns error if someone else claimed first
```

## Dependencies
- queue: shared storage (gt-???)

## Acceptance
- --claim sets assignee + status atomically
- Double-claim returns clear error
- Works with queue messages

Implemented --claim flag for bd update: sets assignee + status atomically, fails if already claimed. Branch: feature/claim-flag pushed to beads repo.


Polecat Lifecycle Events: Refinery-Witness Coordination

## Problem

Polecat work completion is currently treated as a single event (MR submission), but the true completion is when the Refinery merges the work. This creates a lifecycle gap:

1. Polecat submits MR → considered "done" by Witness
2. But MR might fail to merge (conflicts, test failures)
3. No one notifies anyone when merge actually succeeds

## Solution: Two-Event Lifecycle

**Event 1: MR Submitted**
- `gt mq submit` notifies Witness
- Witness verifies submission was clean
- Polecat can go idle (but worktree retained)
- If submission had issues, Witness can help

**Event 2: MR Merged**
- Refinery sends `LIFECYCLE: work merged` to Witness
- Witness updates polecat state to `merged`
- Worktree now eligible for full cleanup/recycling

## Village Sibling Watch

For robustness, patrol roles check on their siblings:
- Refinery checks Witness via `gt peek`
- Witness checks Refinery via `gt peek`
- Creates defense in depth - if primary notification fails, someone catches it

## Recovery

If Refinery misses sending lifecycle notification:
- Witness polecat-scan can detect: polecat in mr_submitted but MR shows merged
- Deacon orphan-check can detect: merged MRs with stale polecats


Refinery: Add lifecycle-notify step to patrol

After successful merge in handleSuccess(), send lifecycle notification to Witness.

## Implementation

1. Add new mail type: `LIFECYCLE: work merged`
2. In engineer.go handleSuccess(), after closing MR and source issue:
   ```
   gt mail send <rig>/witness -s "LIFECYCLE: work merged" -m "
   Worker: <polecat>
   MR: <mr-id>
   Issue: <source-issue>
   Commit: <merge-commit>
   Action: Polecat work merged. Worktree eligible for recycling.
   "
   ```

3. Update mol-refinery-patrol to include lifecycle-notify step between merge-push and loop-check

## Acceptance
- Successful merges send mail to Witness
- Mail includes worker name, MR id, source issue, commit SHA


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)


MQ Submit: Notify Witness on MR submission

When `gt mq submit` is run, notify the Witness so it can verify the submission.

## Implementation

1. In mq_submit.go after successful MR creation:
   ```
   gt mail send <rig>/witness -s "LIFECYCLE: mr submitted" -m "
   Worker: <polecat>
   MR: <mr-id>
   Branch: <branch-name>
   Target: <target-branch>
   Action: Verify MR submission, help polecat if needed.
   "
   ```

2. This happens BEFORE the existing polecat auto-cleanup logic

## Acceptance
- MR submission sends notification to Witness
- Witness receives mail with all relevant details
- Works for both polecat and crew submissions


Witness: Verify MR submission on notification

When Witness receives `LIFECYCLE: mr submitted`, verify the submission was clean.

## Implementation

1. Add handler for "LIFECYCLE: mr submitted" mail
2. Check MR status: `gt mq status <mr-id>`
3. If MR looks good (status=open, no errors): log success, allow polecat to idle
4. If MR has issues:
   - Check polecat git state
   - Nudge polecat to fix if session still alive
   - Log issue for monitoring

## Acceptance
- Witness verifies MR after submission notification
- Can detect problematic submissions
- Provides early intervention opportunity


Polecat state tracking: Add mr_submitted and merged states

Track polecat lifecycle state separate from session state.

## New States

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

## Implementation

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

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


Refinery patrol: Add sibling-check step

Refinery should check on Witness health as part of patrol (village sibling watch).

## Implementation

1. Add `sibling-check` step to mol-refinery-patrol (early in cycle)
2. Use `gt peek <rig>/witness 20` to check Witness output
3. Look for signs of health:
   - Recent activity (tool calls, log messages)
   - No error stack traces
   - Responsive to pings
4. If Witness seems stuck:
   - Send status request mail
   - Note for potential escalation
   - Don't block Refinery work

## Acceptance
- Refinery checks Witness each patrol cycle
- Anomalies logged
- Non-blocking (Refinery continues even if Witness is down)
