gt rig reset: clear stale mail on reset/land

## Problem

When resetting or landing a rig/town, stale mail messages can confuse agents on startup. Old handoff messages, daemon notifications, and inter-agent mail should be cleaned up as part of reset.

## Current State

- `gt rig reset` exists but doesn't clear mail
- Stale messages accumulate (e.g., daemon SHUTDOWN messages)
- Agents may read outdated context on startup

## Proposed Behavior

`gt rig reset` and `gt town reset` should:
1. Close all open messages (`--type=message`) in the relevant beads
2. Optionally preserve pinned handoff beads (clear content, keep bead)
3. Log what was cleaned up

```bash
gt rig reset gastown          # Clears gastown mail
gt rig reset gastown --mail   # Only clear mail, keep other state
gt town reset                 # Clears all town-level mail
gt town reset --all           # Clears mail in all rigs too
```

## Implementation

1. Query `bd list --type=message --status=open`
2. Close each with reason 'Cleared during reset'
3. For pinned handoffs: `bd update <id> --description=''` instead of close


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.

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.

Witness pre-kill verification protocol

Add pre-kill verification protocol to Witness CLAUDE.md template.

## Protocol for Witness Prompting

```markdown
## Pre-Kill Verification Protocol

Before killing any worker session, verify workspace is clean.

### Verification Steps

When a worker signals done:

1. **Capture worker state**:
```bash
town capture <polecat> "git status && git stash list && bd sync --status"
```

2. **Assess the output** (use your judgment):
- Is working tree clean?
- Is stash list empty?
- Is beads synced?

3. **Decision**:
- **CLEAN**: Proceed to kill session
- **DIRTY**: Send nudge with specific issues

### Nudge Templates

**Uncommitted Changes**:
```
town inject <polecat> "WITNESS CHECK: Uncommitted changes found. Please commit or discard: <files>. Signal done when clean."
```

**Beads Not Synced**:
```
town inject <polecat> "WITNESS CHECK: Beads not synced. Run 'bd sync' then commit. Signal done when complete."
```

### Kill Sequence

Only after verification passes:
```bash
town kill <polecat>
town sleep <polecat>
```

### Escalation

If worker fails verification 3+ times:
```bash
town mail send mayor/ -s "Escalation: <polecat> stuck" -m "Cannot complete cleanup after 3 attempts. Issues: <list>."
```
```

## Implementation

Add to WITNESS_CLAUDE.md template.


Burn and respawn or loop

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

Decision point at end of patrol cycle:

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

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

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

This enables infinite patrol duration via context-aware respawning.


mol-deacon-patrol

Mayor's daemon patrol loop.

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

## Second-Order Monitoring

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

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


Implement gt mq CLI commands

Add gt mq subcommands as sugar over bd:

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

All commands should work with the Beads data plane.

Session cycling UX: smooth transitions via TUI wrapper

## Problem

Current CLI agent session cycling is painful:
- Shell → CC starts → priming → context loads → ready → work → exit/crash → repeat
- Each cycle is 30-60 seconds of cold boot
- No continuity between shell and agent's inner state
- Raw "session not running, starting..." loop is the baseline

## GGT Advantages (already have)

- Beads: Work state survives session death completely
- Mail: Handoff notes from past-self to future-self
- Prime commands: Structured context reload

## Gap: Transition Mechanics

Ideas to explore when actively using CLI:

1. **In-band cycling** - `/restart` or `/cycle` command, agent handles own restart without dropping to shell

2. **Hot standby** - TUI maintains pre-warmed session in background, switch to already-primed agent

3. **Persistent wrapper** - Bubbletea TUI stays running across session cycles, CC sessions come/go inside it

4. **Session pooling** - Keep 2-3 primed sessions ready, never wait for cold start

## Deferred

Deliberately P4 until we're actively using the simpler CLI and feel the pain firsthand.

gt molecule current: Show what agent should be working on

Query what an agent identity is supposed to be working on via breadcrumb trail.

## Command
```bash
gt molecule current <identity>
gt molecule current gastown/furiosa
gt molecule current deacon
```

## Logic
1. Find handoff bead for identity (pinned bead titled "<role> Handoff")
2. Parse attachment field → molecule ID
3. If no attachment → "naked" (no active molecule)
4. If attached → load molecule, find current step:
   - bd ready --parent=<mol-id> → next unblocked step
   - Or first in_progress step

## Output
```
Identity: gastown/furiosa
Handoff:  gt-8v2 (Furiosa Handoff)
Molecule: gt-mol-abc (mol-polecat-work)
Progress: 3/8 steps complete
Current:  gt-mol-abc.4 - verify-tests
```

Or if naked:
```
Identity: gastown/angharad
Handoff:  gt-9x1 (Angharad Handoff)
Molecule: (none attached)
Status:   naked - awaiting work assignment
```

## Use Cases

- Witness verifying polecat progress
- Debug: "why isnt this polecat working?"

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


Batch work landing report generation

Generate reports on batch work completion.

## Trigger

When all children of an epic are closed, generate a completion report.

## Report Contents

- Epic metadata (ID, title, created by, duration)
- Task summary (completed counts, timing)
- Per-task details (issue, assignee, time taken)
- Git stats (commits merged, lines changed)
- Cleanup stats (branches deleted)

## Output Locations

1. Mail to Mayor - summary report
2. Optional: save to file with --save flag

## Command

```bash
gt report --epic <epic-id> [--save report.md]
```

## Format

Markdown with sections:
- Summary
- Tasks
- Workers
- Timeline

## Note

This replaces the swarm-based reporting (gt-662). Reports are generated from epic/issue data, not from separate swarm state files.

Add gt hook command (wrapper for bd hook)

Add a thin wrapper command `gt hook` that calls `bd hook` to inspect what's pinned to an agent's hook.

## Usage

```bash
gt hook                    # Show what's on current agent's hook
gt hook --agent deacon     # Show Deacon's hook
gt hook --agent gastown/furiosa  # Show polecat's hook
```

## Implementation

Thin wrapper in gt that:
1. Determines current agent identity
2. Calls `bd hook [--agent <name>]`
3. Formats output for gt context

## Why gt wrapper?

- Consistent with gt ecosystem (gt mail, gt status, etc.)
- Can add gt-specific context (session status, etc.)
- Easier discovery for gt users

Support space-separated rig/polecat syntax in gt polecat commands

## Problem
`gt polecat remove beads obsidian` fails with:
```
Error: invalid address 'beads': invalid address format: expected 'rig/polecat', got 'beads'
```

Requires slash syntax: `gt polecat remove beads/obsidian`

## Proposal
Support both syntaxes for ergonomics:
```bash
gt polecat remove beads/obsidian    # address syntax (current)
gt polecat remove beads obsidian    # positional syntax (proposed)
```

## Implementation
In polecat subcommands that take rig/polecat addresses:
- If arg contains `/`, use as-is
- If two args without `/`, join with `/`
- Apply to: remove, status, sync, reset, done

```go
func normalizePolecatAddress(args []string) string {
    if len(args) == 1 && strings.Contains(args[0], "/") {
        return args[0]
    }
    if len(args) == 2 {
        return args[0] + "/" + args[1]
    }
    // error handling...
}
```

## Rationale
- Unambiguous context - polecat commands always take rig + name
- Matches positional arg patterns in docker, kubectl, etc.
- Reduces agent friction (natural first guess is space-separated)
- Slash syntax remains valid for consistency with mail addresses


Design: Collapse mail into beads

## Proposal

Replace the separate mail system (JSONL inboxes) with beads issues using a naming convention.

## Rationale

If all state should be in beads (work items, swarm state, dependencies), why have a separate system for messages? Mail is just:
- Handoffs (agent → self)
- Commands (Mayor → Refinery)
- Escalations (Witness → Mayor)

These can all be beads issues with a special prefix.

## Design

### Convention
- Messages use `@-` prefix: `@-witness-1734012345`
- Assignee = recipient
- Status: open = unread, closed = read/acknowledged
- Priority 0 = urgent

### Commands (thin wrappers)
```bash
gt mail send witness -s "Subject" -m "Body"
  → bd create --prefix=@ --title="Subject" --assignee=witness --description="Body"

gt mail inbox
  → bd list --prefix=@ --assignee=$(gt whoami) --status=open

gt mail read @-abc
  → bd show @-abc && bd close @-abc
```

### Notification
Daemon watches for new `@-` issues and pokes relevant sessions.
Or: agents poll on heartbeat (simpler).

## What We Remove
- `mail/inbox.jsonl` files
- Mail JSONL read/write code
- Separate delivery mechanism

## What We Keep
- `gt mail` CLI (as wrapper)
- Handoff semantics
- Notification (via daemon or polling)

## Benefits
- One system, one sync, one query interface
- All communication in git history
- Simpler architecture

## Risks
- Beads prefix filtering must be efficient
- Namespace collision with user prefixes
- Performance for high-frequency messages (probably fine for handoffs)

## Decision Point
Do we need first-class mail support in beads (`bd mail` commands) or is convention sufficient?

Beads epic templates for batch work patterns

Optional: Define templates for common batch work patterns.

## Concept

A template encodes a workflow pattern that can be instantiated as beads:

```yaml
# templates/batch-basic.yaml
name: basic-batch
description: Simple batch work pattern
phases:
  - name: startup
    issues:
      - title: "Verify workers ready"
  - name: working
    # Actual work issues added separately
  - name: cleanup
    issues:
      - title: "Merge all branches"
      - title: "Clean up workers"
      - title: "Report to Mayor"
```

## Usage

```bash
gt spawn --template basic-batch --epic gt-u1j --workers 3
```

Creates beads epic with template phases + actual work from gt-u1j children.

## Decision Point

Templates are OPTIONAL. The core design (beads as state, multi-wave orchestration) works without templates. Templates are sugar for common patterns.

Consider deferring to P3 or dropping entirely if beads epics with dependencies suffice.

## Note

No "swarm IDs" involved - templates just pre-populate epic/issue structure.

Hook ergonomics: auto-replace completed pins

## Problem

When pinning a new bead, if the old pinned bead is complete, the new pin should automatically replace it. Currently this fails and requires manual unpinning (which doesn't exist as a command).

Observed friction:
1. Old patrol wisp 100% complete, still pinned
2. Created new patrol wisp
3. `gt mol attach` failed: 'not pinned'
4. Tried to close old wisp: 'cannot close pinned issue'
5. Tried `gt hook unpin`: command doesn't exist
6. Stuck in limbo

## Proposed fix

- `gt hook <new-bead>` auto-replaces if old pin is complete
- Require `--force` if old pin is incomplete
- `gt mol attach` should auto-pin if bead isn't pinned

## Orphan detection

Unpinned incomplete molecules aren't stale orphans until they create graph pressure (blocking other work). Orphan detection should focus on dependency blocking, not just 'unpinned' status.

gt sling --force: return displaced work to ready pool

When slinging with --force to an agent with occupied hook, the displaced molecule should be returned to the ready pool rather than silently orphaned.

Current behavior:
- --force overwrites the hook attachment
- Previous work becomes orphaned (still assigned but not pinned)

Desired behavior:
1. Unpin the displaced molecule (clear assignee, set pinned=false)
2. Print warning in tool output: 'Warning: displaced gt-xxx back to ready pool'
3. Proceed with new sling

This ensures:
- No silent data loss
- Agent sees the warning and can act on it
- Human caller sees what happened
- Displaced work is discoverable via 'bd ready'

Implementation location: checkHookCollision() or the sling handlers themselves (after the --force check passes)


Burn and respawn or loop

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

Decision point at end of patrol cycle:

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

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

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

This enables infinite patrol duration via context-aware respawning.

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)


mol-deacon-patrol

Mayor's daemon patrol loop.

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

## Second-Order Monitoring

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

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


Molecule format bridge: convert embedded markdown to child issues

## Problem

Two molecule formats exist:
1. **Old (gastown builtin)**: Steps embedded as markdown in Description field, parsed by ParseMoleculeSteps()
2. **New (bd mol)**: Steps as child issues in proper beads DAG

The daemon's InstantiateMolecule() uses the old format. bd mol spawn uses the new format.

## Options

### Option A: Require child issues (new format)
- Update daemon to use bd mol spawn instead of InstantiateMolecule
- Deprecate embedded markdown format
- Pro: One format, simpler
- Con: Breaking change for existing molecules

### Option B: Build a bridge
- In InstantiateMolecule, detect format:
  - If Description has ## Step: markers → parse to child issues
  - If issue has children with template label → use directly
- Convert old format to new format on instantiation
- Pro: Backward compatible
- Con: More complexity

## Recommendation

Option B - build the bridge. On instantiation, convert markdown steps to child issues. This unifies execution while preserving authoring flexibility.

gt context --usage: estimate remaining context via tmux line count

## Summary

Implement `gt context --usage` to estimate remaining context capacity.

## Approach

Use tmux scrollback buffer line count as proxy for token usage:
- `tmux capture-pane -p | wc -l` gives current line count
- Heuristics (tunable per model):
  - Opus 4.5: ~1800 lines = warning threshold
  - ~2000+ lines = critical, need handoff

## Output Format
```
Context Usage: 1642 lines (~82%)
Status: WARNING - consider handoff soon
```

## Notes
- Heuristics are model-specific, need config
- Line count is proxy, not exact token count
- Good enough for autonomous patrol decisions

4. For each merged branch:
   - gt mail send <rig>/witness -s "MERGED: polecat/<name>" -m "Branch merged successfully"
   - Delete the MERGE_READY mail
"""
depends_on = ["inbox-check"]
```

## Queue State
Refinery agent tracks queue in `state.json`:
```json
{
  "merge_queue": ["polecat/foo", "polecat/bar"],
  "last_merged": "polecat/baz"
}
```

## Why This Works
- Refinery Claude agent runs formula
- Agent handles conflicts with judgment
- Mail is coordination primitive
- State persists in agent's state.json

## Files
- formulas/mol-refinery-patrol.formula.toml


Tmux status line: rig color themes and worker identity display

## Summary

Customize tmux status line for Gas Town workers with:
1. Per-rig configurable color themes
2. Clear worker name and role visibility

## Current Problem

- Only mayor shows in status line (and truncated)
- Can't tell which rig/worker you're looking at
- All sessions look the same

## Proposed Design

### Per-rig colors
```yaml
# In rig config or beads
theme:
  primary: '#ff6600'    # Orange for gastown
  secondary: '#333333'
  accent: '#ffcc00'
```

### Status line format
```
[gastown/Rictus] polecat | gt-70b3 | branch: polecat/Rictus
[beads/emma] crew | working | branch: main
[mayor] coordinator | idle
```

### Components
- Rig name with rig color
- Worker name
- Role (polecat/crew/mayor/witness/refinery)
- Current issue or status
- Branch name

## Configuration

Could use pinned beads for this (see gm-w13, beads-6v2):
- `bd show <rig>-theme` returns theme config
- Stored as pinned bead, always available
- Part of 'config in beads data plane' initiative

Implementation complete. Core features: per-rig color themes, dynamic status line with issue/mail indicators, gt theme/issue commands. Ready for testing.

Config package: Config, State types and JSON serialization

Config and state types with JSON serialization.

## Town Config (config/town.json)

```go
type TownConfig struct {
    Type      string    `json:"type"`       // "town"
    Version   int       `json:"version"`    // schema version
    Name      string    `json:"name"`       // town identifier
    CreatedAt time.Time `json:"created_at"`
}
```

## Rigs Registry (config/rigs.json)

```go
type RigsConfig struct {
    Version int                `json:"version"`
    Rigs    map[string]RigEntry `json:"rigs"`
}

type RigEntry struct {
    GitURL   string    `json:"git_url"`
    AddedAt  time.Time `json:"added_at"`
    BeadsConfig *BeadsConfig `json:"beads,omitempty"`
}

type BeadsConfig struct {
    Repo   string `json:"repo"`   // "local" | path | git-url
    Prefix string `json:"prefix"` // issue prefix
}
```

## Agent State (*/state.json)

```go
type AgentState struct {
    Role       string    `json:"role"`       // "mayor", "witness", etc.
    LastActive time.Time `json:"last_active"`
    Session    string    `json:"session,omitempty"`
    Extra      map[string]any `json:"extra,omitempty"`
}
```

## Interface

```go
func LoadTownConfig(path string) (*TownConfig, error)
func SaveTownConfig(path string, config *TownConfig) error

func LoadRigsConfig(path string) (*RigsConfig, error)
func SaveRigsConfig(path string, config *RigsConfig) error

func LoadAgentState(path string) (*AgentState, error)
func SaveAgentState(path string, state *AgentState) error
```

Plugin/molecule catalog integration design

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

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

Not blocking launch. Future design investigation.

Fix failing beads tests: TestIntegration and TestPolecatWorkMolecule


Refactor gt swarm to use beads backing

Migrate gt swarm commands from .runtime/swarms.json to beads molecules.

Current gt swarm stores state in .runtime/swarms.json - violating discovery over tracking.
The refactored version should use bd swarm create/status to work with beads molecules.

Implementation:
- gt swarm create calls bd swarm create
- gt swarm status calls bd swarm status
- gt swarm list queries bd list --mol-type=swarm
- Remove .runtime/swarms.json dependency

CROSS-RIG DEPENDENCIES (must complete first in beads repo):
- bd-oxgi: mol_type schema field
- bd-fa1q: bd swarm create command
- bd-5x0j: bd swarm status command

Create PolecatArmMolecule() for per-polecat inspection

Add PolecatArmMolecule() to builtin_molecules.go.

Steps:
- capture: Capture tmux output
- assess: Categorize state
- load-history: Get nudge counts
- decide: Apply nudge matrix
- execute: Take action

Uses variable substitution:
- {{polecat_name}}
- {{rig}}

This proto is bonded dynamically by survey-workers step.


Phase 1.4: Basic patrol runner in Deacon

Deacon CLAUDE.md and prime context for patrol execution.

## Deacon Context
- Update Deacon CLAUDE.md with patrol instructions
- On wake: check pinned bead for attachment
- If attached: resume molecule from current step
- Execute steps, close each when done
- On final step: burn molecule, go naked

## gt prime Enhancement
- Detect if agent has attached molecule
- Show molecule progress in prime output
- Include patrol-specific instructions

Depends: gt-rana.3


Review: Witness patrol template changes (gt-h1n5)

Polecat rictus implemented significant witness.md.tmpl changes: banners, wisp-based execution, handoff bead attachment, loop-or-exit, patrol summary. Review for correctness and consistency with deacon pattern.


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

Add mutex to swarm.Manager for thread safety

attached_args: Add swarm.Manager mutex for thread safety

Fix potential race condition in swarm manager's map access.

## Files to modify
- internal/swarm/manager.go
- internal/swarm/manager_test.go (add concurrency test)

## Problem
The swarms map[string]*Swarm is accessed without synchronization:
```go
type Manager struct {
    swarms map[string]*Swarm  // No mutex protection
}
```

Multiple goroutines could call Create(), GetSwarm(), etc. simultaneously.

## Implementation
```go
type Manager struct {
    mu     sync.RWMutex
    swarms map[string]*Swarm
}

func (m *Manager) GetSwarm(id string) *Swarm {
    m.mu.RLock()
    defer m.mu.RUnlock()
    return m.swarms[id]
}
```

## Acceptance criteria
- [ ] sync.RWMutex added to Manager struct
- [ ] All map accesses protected by mutex
- [ ] RLock for reads, Lock for writes
- [ ] Concurrency test added
- [ ] go test -race ./internal/swarm/... passes


mol-witness-patrol

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

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

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

## The Christmas Ornament Shape

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

```

                 ⬣ base (cleanup)
```

## Phases

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

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

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

## Dynamic Arms

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

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

## Activity Feed

This design enables real-time visibility:

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

## Storage

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

## Dependencies

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

mol-deacon-patrol

Mayor's daemon patrol loop.

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

## Second-Order Monitoring

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

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


mol-polecat-work

Full polecat lifecycle from assignment to decommission.

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

Variables:
- gt-1wmw - The source issue ID being worked on

Crew CLAUDE.md overwritten by polecat template

The crew worker CLAUDE.md files (crew/max, crew/joe, crew/jack) have been overwritten with the polecat-CLAUDE.md template content.

**Expected**: Crew workers should have mayor-like context (they share the rig repo, work on main branch, plan work)

**Actual**: Crew CLAUDE.md says 'Polecat ace' and includes polecat-specific instructions (don't push to main, wait for Witness to kill session, etc.)

**Impact**:
- Crew workers getting wrong identity context
- Ready Front planning guidance in gotchas section was lost
- Crew workers told not to push to main (but they should)

**Root cause**: Likely gt polecat template deployment hit crew directories

**Fix needed**:
- Restore crew CLAUDE.md template (or create one if missing)
- Ensure template deployment only targets polecats/ directories
- Add Ready Front planning section to crew template


Evaluate pending async gates

Evaluate pending async gates.

Gates are async coordination primitives that block until conditions are met.
The Deacon is responsible for monitoring gates and closing them when ready.

**Timer gates** (await_type: timer):
Check if elapsed time since creation exceeds the timeout duration.

```bash
# List all open gates
bd gate list --json

# For each timer gate, check if elapsed:
# - CreatedAt + Timeout < Now → gate is ready to close
# - Close with: bd gate close <id> --reason "Timer elapsed"
```

**GitHub gates** (await_type: gh:run, gh:pr) - handled in separate step.

**Human/Mail gates** - require external input, skip here.

After closing a gate, the Waiters field contains mail addresses to notify.
Send a brief notification to each waiter that the gate has cleared.


request-shutdown

Send shutdown request to Witness.
Wait for termination.

The polecat is now ready to be cleaned up.
Do not exit directly - wait for Witness to kill the session.

Refinery Role Definition

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

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

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

## The Engineer Mindset

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

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

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

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

## Propulsion Principle

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

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

## Sequential Rebase Protocol

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

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

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

## Verification Gate

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

## Commands

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

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

### Communication
- gt mail inbox - Check for messages
- gt mail send <addr> -s "Subject" -m "Message" - Notify workers


@group dynamic resolution in mail router

Wire agent bead queries into mail router for @group addresses.

## Updated Approach (post agent-as-bead)

Agent discovery now uses bead queries instead of filesystem scanning:

```bash
# Instead of filesystem scan
bd list --type=agent --rig=gastown

# Filter by role
bd list --type=agent --role_type=witness
bd list --type=agent --role_type=crew --rig=gastown
```

## Deliverables

1. Parse @group syntax in router:
   - @rig/gastown → bd list --type=agent --rig=gastown
   - @town → bd list --type=agent
   - @witnesses → bd list --type=agent --role_type=witness
   - @crew/gastown → bd list --type=agent --role_type=crew --rig=gastown

2. Fan-out at send time:
   - Resolve @group to list of agent bead IDs
   - Create N message copies (one per recipient)
   - Each recipient gets their own message

3. Update gt mail send to handle @group

## Dependencies
- Agent bead schema (gt-ikyo1) - enables type=agent queries
- Agent beads must exist for resolution to return results

## Acceptance
- @rig/gastown sends to all gastown agents
- Each recipient has own message copy
- Works with existing mail infrastructure

Crew workers: design documentation and remaining work

## Summary

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

## Current Implementation

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

### Crew vs Polecat

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

## Known Bugs

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

## Potential Enhancements

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


File locking for concurrent access

Add file locking for concurrent access safety.

## At-Risk Files
- .gastown/swarms.json (or per-swarm state.json)
- .gastown/refinery.json
- polecats/<name>/state.json
- inbox.jsonl files

## Go File Locking
Use syscall.Flock for advisory locking:
```go
type FileLock struct {
    file *os.File
}

func AcquireLock(path string, timeout time.Duration) (*FileLock, error) {
    f, err := os.OpenFile(path+".lock", os.O_CREATE|os.O_RDWR, 0644)
    if err != nil {
        return nil, err
    }
    // Use syscall.Flock with timeout
}

func (l *FileLock) Release() error
```

## Integration Pattern
```go
func (m *Manager) saveState(ref *Refinery) error {
    lock, err := AcquireLock(m.stateFile(), 5*time.Second)
    if err != nil {
        return fmt.Errorf("could not acquire lock: %w", err)
    }
    defer lock.Release()

    // Read-modify-write cycle
}
```

## New Package
internal/filelock/
├── lock.go     # FileLock, AcquireLock
└── lock_test.go

## Apply To
- internal/refinery/manager.go: loadState/saveState
- internal/cmd/swarm.go: SwarmStore
- internal/mail/mailbox.go: Append, rewrite
- internal/polecat/manager.go: state operations

## Timeout Handling
Default 5 second timeout. Return error if lock not acquired.

## Acceptance Criteria
- [ ] Lock files created (.lock extension)
- [ ] Timeout on lock contention
- [ ] All state files protected
- [ ] Locks released on error paths

Computed range expansion (for-each over expressions)

Support for-each expansion over computed ranges, not just static lists:

for-each:
  var: move_num
  range: "1..2^{disks}"  # Computed at cook time

This enables formulas like Towers of Hanoi where the step count is a function of input variables. The range expression is evaluated during cooking.

Day 2.7: Bootstrap creates agent beads

Bootstrap commands must create agent beads for ZFC compliance.

## Problem
- `gt install` doesn't create Deacon/Mayor agent beads
- `gt rig add` doesn't create Witness/Refinery agent beads
- `gt doctor` doesn't verify agent beads exist
- Current beads were created manually (not reproducible)

## Impact
Patrol ignition (gt-qpoxz) depends on agent beads existing.
Without bootstrap creating them, fresh installs will fail.

## Required
1. gt install: Create gt-deacon and gt-mayor beads
2. gt rig add: Create gt-witness-<rig> and gt-refinery-<rig> beads
3. gt doctor: Add agent-beads-exist check
4. gt doctor --fix: Create missing agent beads

Implement meta-formula generator in parser

Implement the generator that expands meta-formulas into concrete formulas.

## Implementation

1. Detect type: meta-formula in parser
2. Evaluate for-each values
3. For each value, instantiate the formula template
4. Substitute {var} placeholders with current value
5. Return list of generated Formula structs

## API

    func (p *Parser) ExpandMetaFormula(mf *MetaFormula) ([]*Formula, error)

## Edge Cases

- Empty values list: return empty slice
- Duplicate generated names: error
- Nested meta-formulas: error (not supported initially)

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

Use atomic write pattern for state files

attached_args: Atomic write pattern for state files

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

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

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

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

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

Run `gt doctor` for detailed diagnostics.


Plugin: work-oracle (pre-dispatch analysis)

Plugin for pre-dispatch task analysis and decomposition.

## Purpose

Before dispatching workers for an epic, ask work-oracle to:
- Validate task breakdown
- Identify parallelization opportunities
- Predict conflicts between tasks
- Suggest worker count

## Hook Point

Mayor consults work-oracle before spawning workers.

## Interface

Input (via mail):
- Epic ID with proposed child issues
- Rig context (current state of codebase)

Output (via mail + bead):
- Recommended task groupings
- Dependency suggestions
- Risk assessment (which files might conflict)
- Optimal worker count

## Structure

```

Bug: bd update --parent doesn't persist

The --parent flag on bd update reports success but doesn't persist the parent field.

bd update gt-9kp3t --parent=gt-d0jqp --no-daemon -v
# Output: ✓ Updated issue: gt-9kp3t

bd show gt-9kp3t --json | jq '.[0].parent'
# Returns: null

grep gt-9kp3t .beads/issues.jsonl | head -1 | jq '.parent'
# Returns: null (field not present)
```

**Root cause hypothesis:**
The update handler processes the --parent flag but either:
1. Doesn't write it to the Issue struct
2. Doesn't include it in the JSONL export
3. The field name doesn't match what export expects

**Files to check:**

Ensure refinery is alive

Ensure the refinery is alive and processing merge requests.

**Redundant system**: This check runs in both gt spawn and Witness patrol
to ensure the merge queue processor stays operational.

```bash
# Check if refinery session is running

# Check for merge requests in queue
bd list --type=merge-request --status=open
```

If merge requests are waiting AND refinery is not running:
```bash
gt session start <rig>/refinery
gt mail send <rig>/refinery -s "PATROL: Wake up" -m "Merge requests in queue. Please process."
```

If refinery is running but queue is non-empty for >30 min, send nudge.

Analysis: Beads database size and hygiene strategy

Audit beads database size and plan medium-term hygiene.

## Questions
1. How many issues total (including tombstones)?
2. Size of issues.jsonl?
3. Growth rate per day/week?
4. What percentage are tombstones?

## Hygiene Topics
- Compaction: squash tombstones periodically
- Archival: move old closed issues to archive file
- Pruning: delete truly stale items (test beads, old MRs)
- Sync efficiency: large JSONL = slow sync

## Action Items
- [ ] Count total issues by status
- [ ] Count tombstones
- [ ] Measure file sizes
- [ ] Propose hygiene schedule


Feed daemon: curate raw events into user-facing feed

Goroutine in gt daemon that transforms raw events into curated activity feed.

## Input
- Tails ~/gt/.events.jsonl (raw events from gt, bd, agents)

## Output
- Writes ~/gt/.feed.jsonl (curated, user-facing)

## Processing
1. Filter by visibility tag (drop audit-only events)
2. Dedupe repeated updates (5 molecule updates → "agent active")
3. Aggregate related events (3 issues closed → "batch complete")
4. Future: AI summarization via haiku for complex activity

## Integration
- Runs as goroutine in existing gt daemon
- Starts when daemon starts
- Graceful shutdown on daemon stop

Refinery startup: bond mol-refinery-patrol on start

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

## Current state
- mol-refinery-patrol exists in builtin_molecules.go
- prompts/roles/refinery.md describes the protocol
- Refinery doesn't auto-bond on startup

## Desired behavior
On Refinery session start:
1. gt prime detects RoleRefinery
2. Check for existing in-progress patrol: bd list --status=in_progress --assignee=refinery
3. If found: resume from current step
4. If not found: bd mol bond mol-refinery-patrol --wisp
5. Output patrol context to agent

## Implementation options
A) Add to gt prime (outputRefineryPatrolContext)
B) Add startup hook in refinery CLAUDE.md
C) Both (prime detects, template reinforces)

## Testing
- Start refinery session
- Verify patrol bonds automatically
- Kill mid-patrol, restart, verify resumes

## Depends on
- gt-3x0z.10 (existing issue for Refinery patrol)


Mayor startup protocol prompting

Add startup protocol to Mayor CLAUDE.md template.

## On Session Start

1. Check for handoff:
   town inbox | grep "Session Handoff"

2. If handoff found:
   - Read it: town read <msg-id>
   - Process pending escalations (highest priority)
   - Check status of noted swarms
   - Verify rig health matches notes
   - Continue with documented next steps

3. If no handoff:
   town status     # Overall health
   town rigs       # Each rig
   bd ready        # Work items
   town inbox      # Any messages
   Build your own picture of current state.

4. After processing handoff:
   - Archive or delete the handoff message
   - You now own the current state

## Handoff Best Practices

- Be specific: 'Toast has merge conflict in auth/middleware.go' not 'Toast is stuck'
- Include context: Why decisions are pending, what you were thinking
- Prioritize next steps: What is most urgent
- Note time-sensitive items: Anything that might have changed since handoff


142 instances of error suppression with _ = pattern

- internal/mail/router.go: _ = r.notifyRecipient() - notification ignored

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

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

Add await-work and plugin-run steps to mol-refinery-patrol

## Context

The mol-refinery-patrol needs two additional steps:

### 1. await-work (Decision Point)

Not just 'wait for signal' but a crossroads:
- Check for pending signals (mail, nudge, human)
- Check plugin gates (any plugins need to run?)
- Check maintenance schedule (daily/weekly due?)
- Evaluate context and decide next action

Position: Between burn-or-loop and inbox-check (the loop point)

### 2. plugin-run (Like Deacon)

Refinery needs plugin support for:
- **Monitors**: Flag PRs touching sensitive code
- **Gates**: Block merges under certain conditions
- **Schedulers**: Reorder queue based on priority/urgency
- **Maintenance**: Weekly cleanup, audits, stats
- **Audits**: Log merge statistics, track patterns

Position: After queue-scan, before process-branch

## Implementation

Update RefineryPatrolMolecule() in builtin_molecules.go to include:
- await-work step with decision tree
- plugin-run step with gate types

mol-deacon-patrol

Mayor's daemon patrol loop.

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

## Second-Order Monitoring

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

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

Remove redundant gt prime SendKeys from crew commands

The crew commands (gt crew at, gt crew restart) still send 'gt prime' via SendKeys after session creation:
- internal/cmd/crew_at.go:97, 121

This is now redundant because SessionStart hook handles priming automatically.

**Low priority** - these aren't causing bugs (just duplicate work), unlike the spawn race condition that was fixed. Can be cleaned up when convenient.

Patrol exponential backoff for cost savings

Implement exponential backoff for patrol agents (witness, refinery, deacon) when idle.

## Design (from patrol-system-design.md)

Backoff curve:
- Base interval: 30 seconds
- Multiplier: 2x per idle cycle
- Maximum interval: 10 minutes (configurable cap)

Backoff clears on:
1. gt/bd commands - activity feed daemon detects command execution
2. gt nudge - direct wake signal to agent session
3. Mail received - new message in agent inbox
4. Deacon ping - periodic health check

## Implementation

Track backoff state in patrol molecule:
- current_interval: current sleep duration
- idle_cycles: count of cycles with no work found

On each patrol cycle:
- If work found: reset to base interval
- If no work: double interval (up to cap)

On nudge received:
- Reset to base interval
- Poll immediately

## Files

- Patrol formulas: mol-witness-patrol, mol-refinery-patrol, mol-deacon-patrol
- Or implement in Go daemon layer for backoff timing

## Notes

This is a cost optimization - reduces API calls during quiet periods.
Separate from quiescent state (session killed) - backoff keeps session running.

The daemon ensures Witness is always running.


Day 4.1: Implement gt polecat recycle command

Add gt polecat recycle <name> command:
- Kill the Claude session (tmux kill-session)
- Preserve the sandbox (branch/worktree)
- Update agent bead state to 'stopped'
- Leave for respawn on next step

This enables session-per-step.

Parent: gt-4a2qt


Timer gate evaluation

Implement timer gate type. Format: timer:<duration> (5m, 1h, 24h). Deacon evaluates pending timer gates each patrol cycle. Gate closes when duration elapsed since creation. Simplest gate type - implement first.

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

Phase 1.3: gt doctor checks for ephemeral health

Add doctor checks for ephemeral beads repo.

## Checks

1. **ephemeral-exists**: .beads-ephemeral/ directory exists for each rig
2. **ephemeral-git**: It's a valid git repo
3. **ephemeral-orphans**: Molecules started but never squashed (>24h old)
4. **ephemeral-size**: Warn if ephemeral repo is >100MB (should be cleaned)
5. **ephemeral-stale**: Molecules with no activity in last hour

## Auto-fix

--fix can:
- Create missing ephemeral repo
- Clean up old completed molecules (already squashed)
- NOT auto-squash incomplete molecules (needs AI summary)

Witness session startup (gt witness start)

Implement gt witness start <rig>

Should:
1. Verify rig exists and has witness/ directory
2. Check for existing witness session (don't double-start)
3. Create tmux session: gt-<rig>-witness
4. Start Claude Code with --dangerously-skip-permissions
5. Send gt prime to load context
6. Send startup prompt

Similar pattern to refinery startup in internal/refinery/manager.go


bd ready --type: missing type filter for MQ integration

bd ready lacks --type flag that engineer.go expects.

## Code (internal/refinery/engineer.go)
readyMRs, err := e.beads.ReadyWithType("merge-request")

## Actual bd ready
No --type flag - only supports assignee, label, priority filters.

## Impact
Refinery can't find merge-requests in queue, so MQ doesn't process anything.

## Fix Options
1. Add --type flag to bd ready
2. Use bd list --type=merge-request --status=open instead
3. Both (ready filters for unblocked, list for all)

This is blocking the entire MQ pipeline.


Witness emits activity events

Witness emits events to activity stream for patrol activity:

Events to emit:
- patrol_started: When witness begins patrol cycle
- polecat_checked: When witness checks a polecat
- polecat_nudged: When witness nudges a stuck polecat
- escalation_sent: When witness escalates to Mayor/Deacon
- patrol_complete: When patrol cycle finishes

This replaces stats tracking in .runtime/witness.json


gt feed: Activity feed command with tmux-aware modes

## Context

`bd activity` exists and works well for streaming beads mutation events. However:
- It's not discoverable via `gt` (the agent coordination CLI)
- No tmux-aware behavior for when Gas Town is running in tmux
- The planned TUI (gt-rivr) was tombstoned - need a simpler approach

## Requirements

### Without tmux (standalone mode)
- `gt feed` streams activity to stdout (like `bd activity --follow`)
- Supports filtering by rig, time window, event type
- Works in any terminal

### With tmux (integrated mode)
- Could open/attach to a dedicated activity pane
- Or provide a way to send feed to a specific pane
- Integrate with existing gt tmux session management

## Design Questions

1. **Command name**: `gt feed` vs `gt activity` vs `gt watch`?
2. **Tmux integration**: Dedicated pane? Split? Popup?
3. **Cross-rig aggregation**: Merge events from multiple rig daemons?
4. **Filtering UX**: By rig, by molecule, by event type?

## Implementation Options

**Phase 1: Simple wrapper**
- `gt feed` shells out to `bd activity --follow`
- Add `--rig` flag for filtering
- Works identically with/without tmux

**Phase 2: Tmux-aware**
- Detect if running in gt tmux session
- Offer to open in dedicated pane
- `gt feed --pane` to force pane mode

**Phase 3: Cross-rig** (if needed)
- Aggregate from multiple rig daemons
- Unified activity stream across town

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

## Problem

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

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

## Evidence

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

## Impact

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

## Fix

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

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

Polecat 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).

Patrol 3: 14 sessions healthy, no changes


mol-deacon-patrol

Mayor's daemon patrol loop.

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

## Second-Order Monitoring

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

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

Witness daemon: heartbeat loop, spawn ephemeral agent

Background daemon for agent lifecycle and monitoring.

## Core Responsibilities

1. **Heartbeat monitoring**: Check agent health periodically
2. **Session lifecycle**: Restart agents after handoff (Witness Protection)
3. **Polecat monitoring**: Track worker progress, nudging
4. **Escalation**: Report failures to Mayor

## Session Lifecycle (Witness Protection)

The daemon enables autonomous long-running operation by cycling agent sessions:

```go
type SessionLifecycle struct {
    AgentType string  // "witness", "refinery"
    StatePath string  // path to state.json
}

func (d *Daemon) monitorSessionLifecycle(agent SessionLifecycle) {
    // 1. Detect session exit
    // 2. Check state.json for requesting_cycle: true
    // 3. If cycle requested: start new session, clear flag
    // 4. If unexpected exit: escalate to Mayor
}
```

See architecture.md Key Decision #12: Agent Session Lifecycle.

## Interface

```go
type Daemon struct {
    rig      *Rig
    polecats *PolecatManager
    sessions *SessionManager
    config   DaemonConfig
}

type DaemonConfig struct {
    HeartbeatInterval time.Duration  // default: 30s
    NudgeThreshold    int            // nudges before escalation
    MaxWorkers        int            // from rig config
}

func NewDaemon(rig *Rig) *Daemon
func (d *Daemon) Start() error
func (d *Daemon) Stop() error

// Lifecycle
func (d *Daemon) CycleSession(agentType string) error
func (d *Daemon) SpawnWorker(issueID string) error
func (d *Daemon) ShutdownWorker(polecat string) error
```

## Heartbeat Loop

Every HeartbeatInterval:
1. Check Witness session (restart if cycle requested)
2. Check Refinery session (restart if cycle requested)
3. For each active polecat: assess progress, nudge if stuck
4. Query `bd ready` for new work, spawn up to max_workers

Proto marketplace: shareable molecule templates

Enable sharing protos between Gas Town installations.

## Vision

A public registry of protos that users can pull and use:

```bash
gt proto search "code review"
gt proto install gastown/code-review
gt sling code-review gastown/Toast --wisp
```

## Registry Design

### Local Catalog
`~/gt/molecules/` - user-defined and installed protos

### Remote Registry
`registry.gastown.dev/protos/` (future)
- Browse online catalog
- Version-controlled protos
- Rating/reviews
- Usage statistics

## Proto Package Format

```
gastown-code-review-1.0.0/
├── PROTO.md          # Main proto definition
├── README.md         # Usage documentation
├── LICENSE           # Usage terms
└── plugins/          # For pluggable molecules
    ├── security/
    └── performance/
```

## Commands

```bash
gt proto list              # Show installed protos
gt proto search <query>    # Search registry
gt proto install <name>    # Install from registry
gt proto publish <path>    # Publish to registry
gt proto update            # Update all installed
```

## For Now

Start with local catalog. Marketplace is future phase.
Ensure proto format is registry-compatible from the start.


tmux link-window auto-selects new window, causing agent confusion

## Summary

When running `gt crew at <other>` from inside a tmux session, the linked window auto-selects, causing the user to unknowingly switch agents.

## Root Cause

`internal/tmux/tmux.go:535-538` - `LinkWindow` doesn't use `-d` flag:
```go
_, err := t.run("link-window", "-s", source)  // Missing -d!
```

By default, `tmux link-window` selects the newly linked window.

## Reproduction

1. Be in Max's tmux session talking to Max
2. Ask Max to run `gt crew at joe`
3. Max creates Joe's session and links it
4. User is now in Joe's window without realizing it
5. Max appears to have 'disappeared'

## Fix

Add `-d` flag to prevent auto-selection:
```go
_, err := t.run("link-window", "-s", source, "-d")
```

Wisp directory and format

Define and implement the .beads-wisp directory structure.

## Directory Structure

```
<clone>/.beads-wisp/
  hook-<agent>.wisp.yaml     # Slung work for this agent
  patrol-<id>.wisp.yaml      # Patrol cycle state (future)
```

## Wisp File Format

```yaml
type: slung-work | patrol-cycle
created_at: ISO timestamp
created_by: entity who created it

# For slung-work:
bead_id: gt-xxx
context: optional message

# For patrol-cycle (future):
formula: mol-deacon-patrol
current_step: inbox-check
step_states: {...}
```

## Key Properties

- NOT git tracked (.beads-wisp/ in .gitignore)
- Ephemeral - burned after use
- Local to each clone
- Fast writes (no sync needed)

## Implementation

- internal/wisp/dir.go - Directory creation/management
- internal/wisp/types.go - Wisp type definitions
- internal/wisp/io.go - Read/write operations

Phase 1: Slinging Handoff

# Phase 1: Slinging Handoff

The restart-and-resume loop. This is the fundamental propulsion mechanism.

## What It Does

```bash
gt sling gt-xxx
```

1. Creates a wisp on the agent's hook containing the bead
2. Sends handoff mail (optional context)
3. Triggers session restart (daemon SIGUSR1 or direct respawn)
4. Fresh Claude wakes up
5. SessionStart hook runs `gt prime`
6. Agent reads hook → finds the slung bead
7. Agent executes the work

## Why Wisp, Not Mol

The sling is ephemeral scaffolding. It says "run this bead" - nothing more.
Once the work is picked up, the wisp can be burned. No permanent record needed
for the handoff wrapper itself; the actual work is tracked in the bead.

## Implementation

### gt sling command

```go
// cmd: gt sling <bead-id> [-s subject] [-m message]
func sling(beadID string, subject, message string) {
    // 1. Create wisp on hook
    //    - Creates .beads-wisp/hook-<agent>.wisp.yaml
    //    - Contains: bead_id, slung_at, context

    // 2. Optional: send handoff mail
    //    - gt mail send <self> -s "🤝 HANDOFF: <subject>" -m "<message>"

    // 3. Trigger restart
    //    - For crew: just exit (human restarts)
    //    - For polecats: signal daemon (SIGUSR1)
    //    - For deacon: signal daemon (SIGUSR1)
}
```

### Hook Reading in gt prime

```go
// In gt prime, after loading context:
func checkHook(agent string) *SlungWork {
    wispPath := ".beads-wisp/hook-" + agent + ".wisp.yaml"
    if exists(wispPath) {
        return parseWisp(wispPath)
    }
    return nil
}
```

### Agent Response to Slung Work

When agent wakes and finds slung work:

1. Read the wisp: `hook-<agent>.wisp.yaml`
2. Get the bead ID
3. Show the bead: `bd show <bead-id>`
4. Begin working on it
5. Burn the wisp (it's been picked up

## Files Changed

-  - New command
-  - Wisp creation/reading
-  - Hook check on startup
- Role CLAUDE.md files - Instructions for hook processing

## Acceptance Criteria

- [ ]  creates wisp on hook
- [ ] Agent restart picks up the slung work
- [ ] Work begins automatically (no human nudge)
- [ ] Wisp is burned after pickup

Execute registered plugins

Execute registered plugins.

Scan ~/gt/plugins/ for plugin directories. Each plugin has a plugin.md with
YAML frontmatter defining its gate (when to run) and instructions (what to do).

See docs/deacon-plugins.md for full documentation.

Gate types:
- cooldown: Time since last run (e.g., 24h)
- cron: Schedule-based (e.g., "0 9 * * *")
- condition: Metric threshold (e.g., wisp count > 50)
- event: Trigger-based (e.g., startup, heartbeat)

For each plugin:
1. Read plugin.md frontmatter to check gate
2. Compare against state.json (last run, etc.)
3. If gate is open, execute the plugin

Plugins marked parallel: true can run concurrently using Task tool subagents.
Sequential plugins run one at a time in directory order.

Skip this step if ~/gt/plugins/ does not exist or is empty.

## Behavior by role
- mayor: gt mayor restart (sends Ctrl-C, loop respawns)
- witness: gt witness restart
- refinery: gt refinery restart
- polecat: gt polecat restart (or witness-mediated)

## Command format
Uses backticks for inline bash to detect context, then instructs Claude to run appropriate restart.
