Design org formula hierarchy pattern

Design how organizational formula hierarchies work.

## Pattern

    company-base.formula.yaml (org-wide policies)
      └── team-frontend.formula.yaml (extends company-base)
           └── project-dashboard.formula.yaml (extends team-frontend)

## Key Questions

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

## Proposed Design

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

## Deliverables

1. Document pattern in docs/formula-inheritance.md
2. Define conflict resolution rules
3. Identify implementation tasks


Implement aspect merging across formula chain

Implement merging of aspects when formulas extend each other.

## Current State

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

## Implementation

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

## Files

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

## Tests

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


Add org formula examples and tests

Create example organizational formula hierarchy and tests.

## Examples

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

## Tests

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


Conditional aspects (feature flags)

Apply aspects conditionally based on environment or config. Example: apply security-audit only when env.SECURITY_SCANNING == enabled. Adds 'when' clause to aspect composition.


Review dimensions as aspects

Refactor code-review molecule to use aspects for each review dimension (security, performance, accessibility). More flexible than current pluggable molecule approach - add/remove checks by composing aspects.


Compile-time vs runtime cooking

Distinguish two cooking modes: 1) Compile-time: produces proto with variable placeholders, for modeling/estimation/contractor handoff. 2) Runtime: produces mol with real issue IDs. Compile-time lets you pre-decompose work for untrusted executors or planning purposes.


Document Rig/Cook/Run lifecycle

The rig-cook-run.md spec is written. Propagate terminology to all relevant docs: - molecule-algebra.md (done) - molecular-chemistry.md (done) - vision.md (done) - propulsion-principle.md - sling-design.md - Any agent templates that reference cooking/instantiation


Implement bd bond command for artifact-level composition

Implement the artifact-level bond operator distinct from source-level rigging.

Bond accepts:
- Formula names (cooks inline to ephemeral proto, then bonds)
- Mol IDs (existing liquid work)
- Wisp IDs (existing vapor work)

See molecular-chemistry.md for the full bond table semantics.

**Updated 2025-12-25**: With ephemeral protos (gt-4v1eo), bond takes formula names directly and cooks inline. No pre-cooked proto beads.


Direct formula-to-wisp instantiation (skip proto)

For massive ephemeral workflows (e.g., million-step Towers of Hanoi), allow:

bd wisp towers-of-hanoi --var disks=20

This would cook + wisp in one step, never materializing the proto. Useful when:
- The proto would be huge (1M+ steps)
- The work is ephemeral (wisp, not mol)
- You don't need the intermediate artifact

Implementation: streaming cook that emits directly to wisp storage.

Related: towers-of-hanoi.formula.yaml demonstrates the use case.


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.

Related: towers-of-hanoi.formula.yaml demonstrates the need.
Depends on: gt-8tmz.8 (Runtime dynamic expansion)


Formula error handling and recovery

Specify how cooking errors are reported and recovered:
- What happens when extends chain is broken (missing formula)?
- What happens when aspect pointcut matches nothing?
- What happens when expansion produces invalid structure?
- Graceful degradation vs fail-fast semantics
- Error metadata in cooked protos

Deferred: post-launch polish


Formula versioning and migration strategy

Define how formula versions are managed:
- What does the version field mean? Semver? Integer?
- When a formula changes, what happens to existing protos?
- Do protos track their source formula version?
- Migration path: old proto + new formula = ?
- Backwards compatibility guarantees (if any)

Deferred: post-launch polish


Expansion operators: expand and map (macros)

Implement macro-style expansion operators:
- expand(target, template) - apply template to single step
- map(molecule, template) - apply template to all matching steps

Templates use {target} substitution for step references.
Rule of Five is the canonical example.


Proto debugging and inspection tools

Proto debugging and inspection tools.

With ephemeral protos (gt-4v1eo), this becomes:
- `bd cook <formula> --dry-run` - preview cooked output without persisting
- `bd cook <formula> --json` - output proto as JSON for inspection
- `bd cook <formula> --graph` - visualize step DAG

No persistent proto beads to inspect - formulas are the source of truth.


Formula validation specification

Complete validation rules for formulas:
- Required vs optional fields
- Valid step ID patterns
- Valid pointcut glob syntax
- Variable reference validation
- Compose rule ordering constraints
- Type-specific validation (workflow vs expansion vs aspect)

Deferred: post-launch polish


Consolidate molecular-chemistry.md with rig-cook-run.md

Merge rig-cook-run.md into molecular-chemistry.md as the canonical chemical algebra spec:
- Rig/Cook/Run as the lifecycle backbone
- Full generation graph: Formula → Compound Formula → Proto → Mol/Wisp
- Bond table at artifact level (symmetric)
- Rig operator at source level
- Unified vocabulary
- Archive or redirect rig-cook-run.md


Map expansion should match nested child steps


Expansion var overrides not implemented

ExpandRule.Vars field exists in schema but is ignored during expansion.

## Current State

The vars map in expand rules should override the expansion formula default variables, but currently the Vars field is not used.

## Implementation

1. In ApplyExpansions, pass rule.Vars to expandStep
2. Merge vars with formula defaults (rule.Vars wins)
3. Substitute vars in template placeholders
4. Add test: expansion with var overrides

## Files

- internal/formula/expand.go: ApplyExpansions, expandStep
- internal/formula/expand_test.go: add test case


Inline step expansion (Step.Expand field)

Step.Expand and Step.ExpandVars fields exist in schema but are not implemented.

## Current State

Steps can declare inline expansion:

    steps:
      - id: design
        expand: rule-of-five
        expand_vars:
          iterations: 3

This is more convenient than compose.expand for single-step expansions.

## Difference from compose.expand

- compose.expand: Centralized, applies after all steps parsed
- Step.Expand: Inline, step declares its own expansion

## Implementation

1. During cooking, detect steps with Expand field
2. Load referenced expansion formula
3. Replace step with expanded template (like compose.expand)
4. Pass ExpandVars as variable overrides
5. Handle recursion depth (reuse DefaultMaxExpansionDepth)

## Files

- internal/formula/types.go: Step.Expand, Step.ExpandVars (already defined)
- internal/formula/expand.go: Add inline expansion handling
- internal/formula/expand_test.go: Add test cases

## Depends On

- gt-8tmz.34 (var overrides) should be done first


Validate expanded step IDs are unique


Support nested expansion formulas


Fanout gate: waits-for children aggregation

Formalize the fanout gate pattern where a step waits for all dynamically-bonded children.

## Current State

Formulas already use this pattern informally:

    step: aggregate
    waits_for: "all-children"

But it is not in the algebra spec or implemented in the cooker.

## Proposed Syntax

    step: aggregate
    needs: [survey-workers]
    waits-for: children-of(survey-workers)

Or simpler:

    step: aggregate
    needs: [survey-workers]
    waits-for: all-children

## Semantics

- Step cannot start until ALL children of the referenced step have completed
- Children are dynamically bonded via for-each (gt-8tmz.8)
- This is the "aggregation" half of the Christmas Ornament pattern
- If no children were bonded, the gate passes immediately

## Use Cases

**Witness Patrol:**
- survey-workers bonds N polecat-arms
- aggregate waits for all arms to complete
- Then proceeds to save-state

**Refinery Patrol:**
- Less common (sequential processing), but useful for parallel test runs

## Relationship to gate

This is a variant of gate where the condition is "all children complete" rather than
an arbitrary expression. Could be implemented as:

    gate:
      condition: "children-of(survey-workers).all(status == complete)"

But dedicated syntax is cleaner for this common pattern.

## Dependencies

- Depends on gt-8tmz.8 (for-each creates the children)
- Depends on gt-8tmz.4 (gate infrastructure)


Control flow: loop, gate, branch

Implement control flow operators for the molecule algebra.

## Core Operators

| Operator | Syntax | Purpose |
|----------|--------|---------|
| loop (fixed) | loop: { count: N, body: [steps] } | Fixed iteration |
| loop (conditional) | loop: { until: COND, max: N, body: [steps] } | Bounded conditional iteration |
| gate | gate: { before: step, condition: COND } | Wait for condition before proceeding |
| branch | branch: { from: step, steps: [a,b,c], join: step } | Parallel paths that rejoin |

Conditions evaluated mechanically (step status, output fields) per gt-8tmz.7.

## Design Review (2025-12-25)

Analyzed patrol patterns (witness, deacon, refinery) to verify these constructs
can express real Gas Town workflows. Key findings:

### Insight: Patrol Loop is OUTSIDE the Algebra

The daemon respawns patrols. Each formula describes ONE cycle. This means:
- Formulas don't need "infinite loop with burn-and-respawn"
- loop is only for **inner loops** (refinery's per-branch processing)
- "burn-or-loop" = complete cycle; daemon decides next action
- Context cycling is external, not algebraic

This significantly simplifies the algebra.

### Gap: for-each is Missing

The current proposal doesn't include for-each, but it's essential for patrol patterns:

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

Proposed syntax:

    for-each:
      collection: "survey-workers.output.polecats"
      bond: mol-polecat-arm
      vars:
        polecat_name: "{item.name}"
      parallel: true

This overlaps with gt-8tmz.8 (runtime dynamic expansion). Decision needed:
- Include for-each here as control flow, OR
- Ensure gt-8tmz.8 covers these patterns adequately

### Gap: waits-for Gate Variant

The "fanout gate" pattern (aggregate waits for all dynamically-bonded children)
needs formalization:

    step: aggregate
    waits-for: children-of(survey-workers)

Currently exists in formulas as waits_for: "all-children" but not in the algebra spec.

### What This Covers

With these operators (plus for-each), patrols become fully expressible:

**Witness Patrol:**
- for-each polecat -> bond mol-polecat-arm (parallel)
- gate with waits-for: all-children for aggregation

**Refinery Patrol:**
- for-each branch -> process pipeline (sequential)
- gate for test verification before merge

**Deacon Patrol:**
- for-each plugin -> execute if gate open
- Simple sequence otherwise

### Scope Decision

**Option A**: Implement loop, gate, branch now. Track for-each and waits-for separately.

**Option B**: Expand scope to include for-each and waits-for formalization.

Recommendation: Option A - implement core constructs, create child issues for gaps.


Aspects: AOP cross-cutting concerns

Implement aspect-oriented composition:
- Define aspects with pointcuts and advice
- Apply aspects at bond time: bd bond mol --with-aspect security
- Pointcuts use glob patterns to match join points

Enables security-audit, logging, etc. as reusable concerns.


Selection operators: glob, filter, children

Implement selection operators for targeting:
- step(id) - specific step
- glob(pattern) - pattern match (*.implement)
- filter(predicate) - status/output predicates
- children(step), descendants(step) - tree traversal

Used by advice, expansion, and aspects for targeting.


Condition evaluator for gates and loops

Implement mechanical condition evaluation:
- step.status == 'complete'
- step.output.field == value
- children(step).all(status == 'complete')
- file.exists(path), env.VAR

Keep decidable: no arbitrary code, bounded evaluation.


Runtime dynamic expansion (for-each)

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

## Syntax

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

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

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

Key patrol patterns that require this:

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

## Relationship to gt-8tmz.4

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

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

## Implementation Notes

- Bonds N instances based on step output
- Christmas Ornament pattern: fanout from single step to N parallel children
- Pairs with waits-for gate (gt-8tmz.38) for aggregation
- Collection must be iterable (array in step output)
- Each iteration gets item, index, and parent context in vars


gt sling --on flag for wisp scaffolding

Add --on flag to gt sling for applying forms to existing work:
  gt sling shiny gastown/Toast --on gt-abc123

When --on is specified, implies --wisp (scaffolding existing work).
The form shapes execution of the target bead.


Polecat cleanup should refuse to lose uncommitted work

The system should stubbornly refuse to lose work from a polecat.

## Current Problem

- gt spawn --force bypasses safety checks
- gt shutdown doesn't check for uncommitted work
- Witness cleanup doesn't check git status

## Desired Behavior

Before any polecat cleanup, check:
1. git status - any uncommitted changes?
2. git stash list - any stashes?
3. Unpushed commits on branch?
4. Unsynced beads changes?

If ANY of these exist:
- REFUSE to clean up
- Print clear error message listing what would be lost
- Require explicit --nuclear flag to force (not just --force)

## Implementation

Add to cleanupPolecat() in witness/manager.go:
```go
func (m *Manager) checkUncommittedWork(polecatName string) error {
    dir := m.polecatDir(polecatName)

    // Check git status
    if hasUncommitted, _ := git.HasUncommittedChanges(dir); hasUncommitted {
        return fmt.Errorf("polecat %s has uncommitted changes", polecatName)
    }

    // Check stashes
    if stashCount, _ := git.StashCount(dir); stashCount > 0 {
        return fmt.Errorf("polecat %s has %d stashes", polecatName, stashCount)
    }

    // Check unpushed commits
    if unpushed, _ := git.UnpushedCommits(dir); unpushed > 0 {
        return fmt.Errorf("polecat %s has %d unpushed commits", polecatName, unpushed)
    }

    return nil
}
```

## Affected Commands

- gt shutdown
- gt rig shutdown
- Witness cleanup
- gt spawn --force (should warn if overwriting)

Polecat prompting: gt mq submit on completion

Update Polecat CLAUDE.md prompting to:

1. On task completion, run: gt mq submit --issue <id>
2. This creates a merge-request bead in the queue
3. Engineer will process it

The Polecat self-reports completion to the merge queue.


Schematic: Domain-Level Formula Composition

A Schematic is a coordinated set of formulas defining an entire workflow domain.

## Concept

Like an orchestra score to instrument parts - says how formulas fit together.

```toml
# shiny-engineering.schematic
[schematic]
name = "The Shiny Way"
description = "Full engineering workflow from issue to production"

[formulas]
planning = "@gastown/shiny"
development = "@gastown/polecat-work"
review = "@gastown/review"
release = "@gastown/release"

[flow]
default = "planning >> development >> review >> release"

[constraints]
all_code_reviewed = true
tests_before_deploy = true
```

## Relationship to Other Concepts

- **Schematic** (workflow dimension) = composition of Formulas
- **Campaign** (work dimension) = composition of Epics
- Schematic compiles to Campaign, like Formula compiles to Molecule

## Use Cases

1. Define "The Shiny Way" for a team/org
2. Encode compliance requirements
3. Standardize workflows across projects
4. Enable workflow reuse and sharing

## Open Questions

1. File format - TOML? YAML? Extend formula syntax?
2. Validation - how to verify schematic consistency?
3. Overrides - can project override org schematic?

Daemon: integration test with real lifecycle

Need an end-to-end test that:
1. Starts daemon
2. Starts a test agent session
3. Sends lifecycle request to daemon
4. Verifies session was killed and restarted
5. Cleans up

Could use a mock 'agent' that's just a shell script.

- internal/cmd/polecat.go (836 lines)
- internal/witness/manager.go (808 lines)

Refinery background daemon mode

The refinery 'gt refinery start' command only works in foreground mode (--foreground). Need to implement background daemon mode for production use.

Options:
1. Use a separate tmux session for the refinery
2. Implement proper daemonization
3. Use Claude Code session for the refinery agent

For MVP, option 1 (tmux session) is probably simplest.


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)


Add crew lifecycle support to Deacon

Currently crew sessions (like gastown/crew/max, beads/crew/dave) are marked as 'human-managed' and excluded from automated lifecycle.

## Current State
- `getManager(RoleCrew)` returns `"human"` (handoff.go:273)
- `gt handoff` for crew just prints a message, no lifecycle request sent
- Crew cannot request automated refresh from Deacon

## Desired State
Crew members should be able to request lifecycle actions from Deacon:
- `gt handoff --cycle` sends request to Deacon, which kills/restarts the crew session
- Useful when: context full, running molecules that need fresh session, automation

## Implementation
1. Change `getManager(RoleCrew)` to return `"deacon/"` (or new crew manager)
2. Teach Deacon to recognize crew session naming pattern
3. Add crew to Deacon's respawn loop handling
4. Test with `gt nudge` for reliable message delivery

## Use Case
Running a molecule (e.g., version-bump) and discovering mid-workflow that a fresh session is needed. Agent should be able to request refresh automatically rather than requiring human intervention.

## Related
- gt nudge: reliable message delivery to Claude sessions
- bd mol bond: molecule instantiation (coming in beads)


Work request: gt-976 crew lifecycle support

Hey Max, filed gt-976 for you - adding crew lifecycle support to Deacon.

Currently crew is 'human-managed' and can't request automated refresh. Would be useful for molecules that need fresh sessions mid-workflow.

Key changes:
- getManager(RoleCrew) → return deacon/ instead of human
- Teach Deacon crew session patterns
- Test with gt nudge

Priority 2, no rush but would unblock molecule automation for crew.

gt daemon: Background service management

## Summary

ONE daemon for all Gas Town - a simple Go process (not a Claude agent) that:
1. Pokes agents periodically (heartbeat)
2. Processes lifecycle requests
3. Restarts sessions when agents request cycling

## Architecture

Daemon (gt daemon)
- Pokes Mayor: "HEARTBEAT: check your rigs"
- Pokes each Witness: "HEARTBEAT: check your workers"
- Has inbox at daemon/ for lifecycle requests
- Restarts sessions on cycle requests

## NOT the daemon's job:
- Making decisions (Witnesses do that)
- Running Claude (it's a Go process)
- Processing work (polecats do that)
- Direct polecat management (Witnesses do that)

The daemon is a **dumb scheduler** - poke things, execute lifecycle requests. All intelligence is in agents.

## Commands

- gt daemon start: Start daemon (background)
- gt daemon stop: Stop daemon
- gt daemon status: Show daemon status
- gt daemon logs: View daemon logs

## Daemon Loop

Every heartbeat interval:
1. Poke Mayor
2. For each rig: Poke Witness
3. Process lifecycle requests from daemon/ inbox
4. Check for dead sessions, restart if cycle requested

## Lifecycle Request Handling

Daemon checks its inbox (daemon/) for lifecycle requests:
- From Mayor: cycle/restart Mayor session
- From Witnesses: cycle/restart Witness session

On request:
1. Verify agent state shows requesting_cycle
2. Kill session
3. Start new session
4. Clear requesting_cycle flag

## Poke Protocol

Poke = tmux inject "HEARTBEAT: do your job"
- Agent ignores if already working
- Agent wakes up if idle
- Idempotent - multiple pokes are fine

## Lifecycle Hierarchy

- Daemon manages: Mayor, all Witnesses
- Witness manages: Polecats, Refinery (per rig)
- Crew: self-managed (human workspace)

Federation: Wasteland architecture for cross-town coordination

## Overview

Federation enables Gas Town to scale across machines via **Outposts** - remote compute environments that can run workers.

**Design doc**: docs/federation-design.md

## Outpost Types

| Type | Description | Cost Model |
|------|-------------|------------|
| Local | Current model (tmux panes) | Free |
| SSH/VM | Full Gas Town clone on VM | Always-on |
| CloudRun | Container workers on GCP | Pay-per-use |

## Key Concepts

### Outpost Abstraction
```go
type Outpost interface {
    Name() string
    Type() OutpostType  // local, ssh, cloudrun
    MaxWorkers() int
    Spawn(issue string, config WorkerConfig) (Worker, error)
    Workers() []Worker
    Ping() error
}
```

### Cloud Run Workers
- Persistent HTTP/2 connections solve zero-to-one cold start
- Pay only when working (~$0.017 per 5-min session)
- Scale 0→N automatically
- Git clone via persistent volumes

### SSH/VM Outposts
- Full Gas Town clone on remote machine
- SSH for commands, git for sync
- Good for long-running autonomous work

## Design Principles

1. **Outpost abstraction** - support multiple backends
2. **Local-first** - remote is for overflow/burst
3. **Git as source of truth** - code and beads sync everywhere
4. **HTTP for Cloud Run** - dont force mail onto containers
5. **Graceful degradation** - works with any subset of outposts

Outpost/Worker interfaces: Core abstractions for remote compute

## Overview

Define the core interfaces that all outpost types implement.

## Interfaces

const (
    OutpostLocal    OutpostType = "local"
    OutpostSSH      OutpostType = "ssh"
    OutpostCloudRun OutpostType = "cloudrun"
)

type Outpost interface {
    Name() string
    Type() OutpostType
    MaxWorkers() int
    ActiveWorkers() int
    Spawn(issue string, config WorkerConfig) (Worker, error)
    Workers() []Worker
    Ping() error
    SendMail(worker string, msg Message) error  // optional
}

type Worker interface {
    ID() string
    Outpost() string

## Manual Setup Guide

```markdown
# Setting Up a VM Outpost

## Prerequisites
- GCE VM (or any Linux machine with SSH access)
- SSH key pair
- Git configured on VM

## Steps

1. Install Claude Code on VM:
   ```bash
   ssh user@vm
   npm install -g @anthropic-ai/claude-code
   ```

2. Clone Gas Town:
   ```bash
   mkdir -p ~/ai
   cd ~/ai
   gt install .
   ```

3. Configure Git credentials:
   ```bash
   git config --global user.name "Your Name"
   git config --global credential.helper store
   ```

4. Add outpost to local config:
   ```bash
   gt outpost add ssh \
     --name gce-burst \
     --host 10.0.0.5 \
     --user steve \
     --key ~/.ssh/gce_worker \
     --town-path /home/steve/ai \
     --max-workers 8
   ```

5. Test connectivity:
   ```bash
   gt outpost ping gce-burst
   ```
```

HTTP work server: gt worker serve command

## Overview

HTTP server that runs inside Cloud Run containers, accepting work requests.

## Command

```bash
gt worker serve --port 8080
```

## Implementation

```go
type WorkServer struct {
    port    int
    handler *WorkHandler
}

func (s *WorkServer) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    switch r.URL.Path {
    case "/work":
        s.handleWork(w, r)
    case "/health":
        s.handleHealth(w, r)
    default:
        http.NotFound(w, r)
    }
}

func (s *WorkServer) handleWork(w http.ResponseWriter, r *http.Request) {
    // 1. Parse WorkRequest
    // 2. Clone/pull repo
    // 3. Start Claude on issue
    // 4. Stream WorkEvents as NDJSON
    // 5. Return WorkResult
}
```

## Streaming Response

```go
func (s *WorkServer) streamEvents(w http.ResponseWriter, events <-chan WorkEvent) {
    flusher, _ := w.(http.Flusher)
    encoder := json.NewEncoder(w)
    for event := range events {
        encoder.Encode(event)
        flusher.Flush()
    }
}

HTTP work client: CloudRun dispatch client

## Overview

HTTP client for dispatching work to Cloud Run and streaming results back.

## Implementation

```go
type WorkClient struct {
    serviceURL string
    httpClient *http.Client  // HTTP/2 enabled
}

func NewWorkClient(serviceURL string) *WorkClient {
    return &WorkClient{
        serviceURL: serviceURL,
        httpClient: &http.Client{
            Transport: &http2.Transport{},

CloudRun persistent connections: HTTP/2 keepalive

## Overview

Implement persistent HTTP/2 connections to keep Cloud Run containers warm.

## Problem

Cloud Run has cold start latency when scaling from 0. Persistent connections keep containers warm.

## Implementation

```go
type PersistentConnectionManager struct {
    serviceURL string
    conn       net.Conn
    client     *http2.ClientConn
    mu         sync.Mutex
    lastUsed   time.Time
    keepAlive  time.Duration
}

func (m *PersistentConnectionManager) GetConnection() (*http2.ClientConn, error) {
    m.mu.Lock()
    defer m.mu.Unlock()

    // Reuse existing connection if healthy
    if m.client != nil && m.client.CanTakeNewRequest() {
        m.lastUsed = time.Now()
        return m.client, nil
    }

    // Create new connection
    return m.dial()
}

func (m *PersistentConnectionManager) keepAliveLoop() {
    ticker := time.NewTicker(m.keepAlive / 2)
    for range ticker.C {
        m.mu.Lock()
        if time.Since(m.lastUsed) > m.keepAlive {
            // Connection idle too long, close it
            m.close()
        } else {
            // Send ping to keep alive
            m.ping()
        }
        m.mu.Unlock()
    }
}
```

## Integration with CloudRunOutpost

```go
type CloudRunOutpost struct {
    // ...existing fields...
    connMgr *PersistentConnectionManager
}

func (o *CloudRunOutpost) Spawn(...) {
    conn, err := o.connMgr.GetConnection()
    // Use connection for work dispatch
}
```

## Config

```yaml
outposts:
  - name: cloudrun-burst
    type: cloudrun
    # ...
    keep_alive: 5m  # Keep connection warm for 5 minutes
```

CloudRun cost tracking: Usage monitoring and limits

## Overview

Track Cloud Run usage costs and enforce spending limits.

## Cost Model

Cloud Run pricing (approximate):
- CPU: ~$0.000024/vCPU-second
- Memory: ~$0.0000025/GiB-second
- Requests: ~$0.40/million

For 5-minute worker (2 vCPU, 4GB):
- CPU: 300 × 2 × $0.000024 = $0.0144
- Memory: 300 × 4 × $0.0000025 = $0.003
- **Total: ~$0.017 per session**

## Implementation

```go
type CostTracker struct {
    cpuRate    float64  // per vCPU-second
    memRate    float64  // per GiB-second
    sessions   []SessionCost
    mu         sync.RWMutex
}

type SessionCost struct {
    WorkerID  string
    StartTime time.Time
    EndTime   time.Time
    CPUs      float64
    MemoryGiB float64
}

func (t *CostTracker) RecordSession(workerID string, start, end time.Time, cpus, mem float64) {
    t.mu.Lock()
    defer t.mu.Unlock()
    t.sessions = append(t.sessions, SessionCost{...})
}

func (t *CostTracker) CurrentCost() float64 {
    t.mu.RLock()
    defer t.mu.RUnlock()
    var total float64
    for _, s := range t.sessions {
        duration := s.EndTime.Sub(s.StartTime).Seconds()
        total += duration * s.CPUs * t.cpuRate
        total += duration * s.MemoryGiB * t.memRate
    }
    return total
}
```

## Cost Cap Enforcement

```go
func (o *CloudRunOutpost) Spawn(...) (Worker, error) {
    if o.costCap > 0 && o.costTracker.CurrentCost() >= o.costCap {
        return nil, ErrCostCapExceeded
    }
    // ... spawn worker
}
```

## Config

```yaml
outposts:
  - name: cloudrun-burst
    type: cloudrun
    cost_cap_hourly: 5.00   # Stop spawning if hourly cost exceeds $5
    cost_cap_daily: 50.00   # Daily limit
```

## CLI

```bash
gt outpost status cloudrun-burst
# Shows: Cost (today): $0.42 / $50.00 cap
```

Outpost error handling: Retry logic and resilience

## Overview

Error handling and retry logic for outpost operations.

## Error Types

```go
var (
    ErrOutpostUnreachable = errors.New("outpost unreachable")
    ErrWorkerSpawnFailed  = errors.New("worker spawn failed")
    ErrWorkerTimeout      = errors.New("worker timed out")
    ErrCostCapExceeded    = errors.New("cost cap exceeded")
    ErrAllOutpostsBusy    = errors.New("all outposts at capacity")
)
```

## Retry Policy

```go
type RetryPolicy struct {
    MaxAttempts     int
    InitialBackoff  time.Duration
    MaxBackoff      time.Duration
    BackoffFactor   float64
    RetryableErrors []error
}

func DefaultRetryPolicy() *RetryPolicy {
    return &RetryPolicy{
        MaxAttempts:    3,
        InitialBackoff: 1 * time.Second,
        MaxBackoff:     30 * time.Second,
        BackoffFactor:  2.0,
        RetryableErrors: []error{
            ErrOutpostUnreachable,
            ErrWorkerSpawnFailed,
        },
    }
}
```

## Retry Implementation

```go
func (m *OutpostManager) SpawnWithRetry(issue string, cfg WorkerConfig) (Worker, error) {
    var lastErr error
    backoff := m.retryPolicy.InitialBackoff

    for attempt := 0; attempt < m.retryPolicy.MaxAttempts; attempt++ {
        outpost := m.policy.SelectOutpost(issue, m.outposts)
        if outpost == nil {
            return nil, ErrAllOutpostsBusy
        }

        worker, err := outpost.Spawn(issue, cfg)
        if err == nil {
            return worker, nil
        }

        if !m.isRetryable(err) {
            return nil, err
        }

        lastErr = err
        time.Sleep(backoff)
        backoff = min(backoff * m.retryPolicy.BackoffFactor, m.retryPolicy.MaxBackoff)
    }

    return nil, fmt.Errorf("spawn failed after %d attempts: %w",
        m.retryPolicy.MaxAttempts, lastErr)
}
```

## Outpost Health Tracking

```go
type OutpostHealth struct {
    LastPing      time.Time
    LastError     error
    FailureCount  int
    CircuitBreaker bool  // If true, skip this outpost
}

func (m *OutpostManager) updateHealth(name string, err error) {
    // Track failures, open circuit breaker after N failures
    // Auto-reset after successful ping
}
```

## Config

```yaml
policy:
  retry:
    max_attempts: 3
    initial_backoff: 1s
    max_backoff: 30s

  circuit_breaker:
    failure_threshold: 5
    reset_timeout: 1m
```

## Files

Can be done after basic outpost implementations work.


Outpost integration tests: Mock and E2E testing

## Overview

Integration tests for the outpost system.

## Mock Outpost

```go
type MockOutpost struct {
    name        string
    maxWorkers  int
    spawnDelay  time.Duration
    spawnError  error
    workers     []*MockWorker
}

func (o *MockOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    if o.spawnError != nil {
        return nil, o.spawnError
    }
    time.Sleep(o.spawnDelay)
    worker := &MockWorker{id: uuid.New().String(), issue: issue}
    o.workers = append(o.workers, worker)
    return worker, nil
}
```

## Unit Tests

```go
func TestOutpostManager_SelectOutpost(t *testing.T) {
    // Test policy-based selection
}

func TestOutpostManager_SpawnWithRetry(t *testing.T) {
    // Test retry logic with transient failures
}

func TestCloudRunOutpost_CostTracking(t *testing.T) {
    // Test cost calculation and caps
}
```

## Integration Tests (with mocked Cloud Run)

```go
func TestCloudRunOutpost_Integration(t *testing.T) {
    // Start mock HTTP server
    server := httptest.NewServer(mockWorkHandler())
    defer server.Close()

    outpost := NewCloudRunOutpost(OutpostConfig{
        ServiceURL: server.URL,
    })

    worker, err := outpost.Spawn("test-issue", WorkerConfig{})
    // Assert worker created, events streamed
}
```

## E2E Tests (requires real Cloud Run)

```go
// +build e2e

func TestCloudRunOutpost_E2E(t *testing.T) {
    if os.Getenv("CLOUDRUN_SERVICE_URL") == "" {
        t.Skip("CLOUDRUN_SERVICE_URL not set")
    }
    // Test against real Cloud Run service
}
```

LocalOutpost: Refactor current polecat spawning

## Overview

Refactor current local polecat spawning to implement the Outpost interface.

## Current State

Polecat spawning is ad-hoc. This task wraps it in LocalOutpost.

## Implementation

```go
type LocalOutpost struct {
    name       string
    maxWorkers int
    tmux       *Tmux
    workers    map[string]*LocalWorker
}

func NewLocalOutpost(config OutpostConfig) *LocalOutpost

func (o *LocalOutpost) Type() OutpostType { return OutpostLocal }

func (o *LocalOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    // Create tmux session
    // Start claude in pane
    // Return LocalWorker
}
```

## LocalWorker

```go
type LocalWorker struct {
    id      string
    session string  // tmux session name
    issue   string
    status  WorkerStatus
}

func (w *LocalWorker) Attach() error {
    // tmux attach-session
}
```

## Notes

- This should be a refactor, not new functionality
- Existing polecat code becomes LocalOutpost internals
- Tests should pass before and after

Depends on: gt-9a2.1 (interfaces)

SSHOutpost: Full Gas Town clone on remote VM

## Overview

Implement SSHOutpost for running workers on remote VMs via SSH.

## Model

Remote VM has a full Gas Town clone. SSHOutpost:
- Connects via SSH
- Spawns tmux sessions on remote
- Uses remote git clone for code/beads
- Syncs via git push/pull

## Implementation

```go
type SSHOutpost struct {
    name       string
    host       string
    user       string
    keyPath    string
    townPath   string  // e.g., /home/steve/ai
    maxWorkers int
    conn       *ssh.Client
}

func NewSSHOutpost(config OutpostConfig) (*SSHOutpost, error)

func (o *SSHOutpost) Spawn(issue string, cfg WorkerConfig) (Worker, error) {
    // SSH: create tmux session on remote
    // SSH: start claude in session
    // Return SSHWorker
}

func (o *SSHOutpost) Ping() error {
    // Test SSH connectivity
}
```

## SSHWorker

```go
type SSHWorker struct {
    outpost *SSHOutpost
    id      string
    session string
    issue   string
}

func (w *SSHWorker) Attach() error {
    // SSH + tmux attach (opens terminal)
}

func (w *SSHWorker) Logs() (io.Reader, error) {
    // SSH: tmux capture-pane
}
```

## Prerequisites on Remote VM

1. Gas Town clone at townPath
2. Claude Code installed
3. Git credentials configured
4. SSH key access

## Integration with gt-f9x.7-8

This builds on the Connection interface from gt-f9x.7/8. SSHOutpost uses SSHConnection internally for remote operations.

Depends on: gt-9a2.1 (interfaces), gt-f9x.7 (Connection interface)

Outpost assignment policy: Smart work routing

## Overview

Policy engine for deciding which outpost gets which work.

## Policy Configuration

```yaml
policy:
  # Default order of preference
  default_preference: [local, gce-burst, cloudrun-burst]

  # Rules applied in order
  rules:
    # Background work → Cloud Run (cheap)
    - condition: "priority >= P3"
      prefer: cloudrun-burst

    # Long tasks → VM (persistent)
    - condition: "estimated_duration > 30m"
      prefer: gce-burst

    # Specific epic → specific outpost
    - condition: "epic == gt-abc"
      prefer: local
```

## Implementation

```go
type AssignmentPolicy struct {
    DefaultPreference []string
    Rules             []PolicyRule
}

type PolicyRule struct {
    Condition string   // Simple expression
    Prefer    string   // Outpost name
    Require   string   // Must use this outpost
}

func (p *AssignmentPolicy) SelectOutpost(
    issue Issue,
    outposts map[string]Outpost,
) Outpost {
    // Check rules in order
    for _, rule := range p.Rules {
        if rule.Matches(issue) {
            if op, ok := outposts[rule.Prefer]; ok {
                if op.ActiveWorkers() < op.MaxWorkers() {
                    return op
                }
            }
        }
    }

    // Fall back to default preference
    for _, name := range p.DefaultPreference {
        if op, ok := outposts[name]; ok {
            if op.ActiveWorkers() < op.MaxWorkers() {
                return op
            }
        }
    }

    return nil  // All outposts at capacity
}
```

## Condition Language

Simple expressions, not a full DSL:

```
priority >= P3
priority == P0
estimated_duration > 30m
epic == gt-abc
type == bug
label contains "urgent"
```

Polecat wisp architecture: Proto → Wisp → Mol pattern

Design the three-layer architecture for polecat lifecycle:

## The Insight

Polecats should run a ONE-SHOT WISP (not looping like patrols):

**Step 1: Onboard**
- Read full polecat protocol (polecat.md template)
- Learn Gas Town operation, exit strategies, molecule protocol
- This is the 'how to be a polecat' education

**Step 2: Execute Mol**
- Run the assigned molecule (the actual work item)
- Could span multiple sessions via session continuity
- The mol is pure work content (epic, issue, feature)

**Step 3: Cleanup**
- Run final step of the wisp
- Self-delete / request shutdown

## Three Layers

- **Proto**: polecat.md template (instructions for being a polecat)
- **Wisp**: One-shot harness instantiated from proto (wraps the mol)
- **Mol**: The work item (issue/epic being processed)

## Why This Matters

1. **Separation of concerns**: Protocol (how) vs Work (what)
2. **Reusability**: Same wisp harness wraps any mol
3. **Extensibility**: Plugin points for custom behavior
4. **Session continuity**: Wisp handles multi-session, not the mol
5. **Blurred control/data planes**: Intentional in Gas Town

## Design Questions

1. How does proto (polecat.md) become a wisp instance?
2. What are the plugin/extension points?
3. Should all 'engineer in a box' mols use proto → wisp → mol?
4. How does this relate to refinery/deacon patterns?

CLI: worker status reporting commands

Worker status reporting CLI for polecats to report progress.

## Commands

### gt worker started
```
gt worker started <issue-id> [-m MESSAGE]
```
Reports work started on issue.

### gt worker progress
```
gt worker progress <issue-id> <0-100> [-m MESSAGE]
```
Reports percentage complete.

### gt worker blocked
```
gt worker blocked <issue-id> <reason> [-m MESSAGE]
```
Reports blocked status with reason.

### gt worker completed
```
gt worker completed <issue-id> [-m MESSAGE]
```
Reports task completion.

### gt worker failed
```
gt worker failed <issue-id> <reason> [-m MESSAGE]
```
Reports task failure.

## Implementation
Each command sends mail to refinery with structured content:
```go
type WorkerStatusReport struct {
    IssueID    string
    Status     string  // started|progress|blocked|completed|failed
    Progress   int     // 0-100 for progress
    Reason     string  // for blocked/failed
    Message    string  // optional detail
    ReportedAt time.Time
}
```

## Message Format
Subject: "[STATUS] <issue-id>: <status>"
Body: JSON-encoded WorkerStatusReport

## Default Recipient
```go
// Determine from context
func getDefaultRecipient() string {
    rig := os.Getenv("GT_RIG")
    if rig != "" {
        return rig + "/refinery"
    }
    return "refinery/"
}
```

## New File
internal/cmd/worker.go

## PGT Reference
gastown-py/src/gastown/cli/worker_cmd.py

## Acceptance Criteria
- [ ] All 5 commands implemented
- [ ] Status sent as mail to refinery
- [ ] Structured JSON body for parsing
- [ ] Works from polecat session context

gt spawn should create fresh polecat worktree, never reuse

Currently gt spawn tries to reuse existing polecats, which causes:

1. Stale beads database
2. Stale code (behind main/integration)
3. Old inbox messages
4. Git history pollution

## Current Behavior

gt spawn:
1. Looks for idle polecat in pool
2. If found, reuses existing worktree
3. Assigns new issue

## Desired Behavior

gt spawn:
1. Always create FRESH polecat from current main/integration
2. Fresh worktree with clean beads
3. No reuse of old worktrees

## Name Pool Still Useful

Keep name pool for:
- Allocating themed names (mad-max, etc.)
- Tracking which names are in use

But worktrees should be created fresh each time.

## Implementation

In spawn.go, before starting work:
1. If worktree exists: remove it first
2. Create fresh worktree from integration branch
3. Sync beads from rig to polecat
4. Then proceed with work assignment

This ensures polecats always start with latest code and beads.

Deacon tmux status bar: heartbeat timing and patrol state

## Problem

The deacon shows patrol output but lacks real-time observability:
- No indication of when last heartbeat occurred
- No indication of when next heartbeat is scheduled
- No visibility into current patrol step

## Desired Behavior

The tmux status bar for gt-deacon should show:

```
⛪ Deacon | ❤ 2m ago | ⏰ 3m | 📍 health-scan (3/7)
```

Components:
- **Role icon**: ⛪ (deacon identity)
- **Last heartbeat**: ❤ 2m ago (time since last heartbeat file update)
- **Next heartbeat**: ⏰ 3m (time until daemon would poke)
- **Current step**: 📍 health-scan (3/7) (current patrol atom, step N of M)

## Implementation

1. **Read heartbeat.json** for last update time
2. **Calculate next poke** based on daemon interval (default 5m)
3. **Read current wisp** from .beads-wisp/ to get patrol progress
4. **Update tmux status** periodically or on state change

Options:
- tmux status-right with shell script
- gt deacon status --tmux for formatted output
- Hook into patrol step completion

gt spawn should verify daemon is running for polecat triggering

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

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

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

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

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

Daemon must delete LIFECYCLE messages after processing

## Problem

Crew workers were being killed every 5 minutes.

## Root Cause

Old stale LIFECYCLE messages from days ago were sitting in the deacon's inbox. The daemon's ProcessLifecycleRequests() was re-finding and re-processing them every 5-minute heartbeat cycle.

The closeMessage() function in lifecycle.go calls 'gt mail delete' but failures are silent - the message stays in the inbox and gets reprocessed on the next heartbeat.

## Fix Required

1. Ensure closeMessage() actually deletes the message
2. If delete fails, log the error AND mark the message as read so it's not reprocessed
3. Consider adding a 'processed' label or moving to a processed folder

Update polecat CLAUDE.md with molecule workflow

Add molecule execution guidance to polecat context:

## What to Add

### Molecule Awareness
- Polecats execute Wisps (ephemeral molecule instances)
- The work assignment mail includes molecule context
- Current step is tracked in the wisp

### Workflow Protocol
1. Read assignment (includes molecule ID and current step)
2. Execute current step
3. Update step status via bd mol step
4. Generate summary when all steps complete
5. Run bd mol squash to compress wisp into digest

### Key Commands
- bd mol show <wisp-id> - view current molecule state
- bd mol step <wisp-id> --status=complete - mark step done
- bd mol squash <wisp-id> --summary='...' - complete molecule

### Summary Generation
When completing work, generate a summary that:
- Lists what was accomplished
- Notes any deviations from the plan
- Captures key decisions made
- This becomes the permanent digest


Refinery background daemon mode

Refinery currently only works in foreground mode. Background daemon is stubbed.

## Current State
manager.go line 128-129:
```go
// Background mode: spawn a new process
// For MVP, we just mark as running - actual daemon implementation in gt-ov2
return nil
```

## Requirements

### 1. Background Process Spawning
```go
func (m *Manager) Start(foreground bool) error {
    if !foreground {
        // Spawn gt refinery start --foreground as subprocess
        cmd := exec.Command(os.Args[0], "refinery", "start", m.rig.Name, "--foreground")
        cmd.Start()  // Don't wait
        // Record PID
    }
}
```

### 2. PID File Management
- Write PID to .gastown/refinery.pid
- Check PID validity on status
- Clean up stale PID files

### 3. Log Output
- Redirect stdout/stderr to .gastown/refinery.log
- Log rotation (optional for MVP)

### 4. Graceful Shutdown
- Handle SIGTERM/SIGINT
- Complete current merge before exit
- Update state to stopped

### 5. Health Check
- Process existence check via kill -0
- Optional: heartbeat file with timestamp

## Files to Modify
- internal/refinery/manager.go: Start(), Status(), process spawning

## Acceptance Criteria
- [ ] gt refinery start <rig> spawns background process
- [ ] gt refinery status shows running with PID
- [ ] gt refinery stop sends SIGTERM and waits
- [ ] Logs written to .gastown/refinery.log
- [ ] Survives terminal close


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

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

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

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

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

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

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

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

gt sling: auto-sync beads in new polecat worktrees

## Problem
`gt sling <bead> <rig>` could fail to pin because polecat worktree branches persisted and diverged from current state.

## Root Cause
- Polecat branches (`polecat/<name>`) were reused across runs
- Stale branches could diverge from main and beads-sync
- Branch reuse logic was complex with fallback behavior

## Solution Implemented
**Fresh unique branches per polecat run**

Instead of syncing beads (Options A/B/C), we changed the branch model:

1. **Unique timestamped branches**: Each polecat run creates `polecat/<name>-<timestamp>`
2. **No branch reuse**: Each spawn starts fresh from current HEAD
3. **Simplified code**: Removed branch existence checks and reset logic
4. **Garbage collection**: Added `gt polecat gc <rig>` to clean up old branches

### Why This Works
- Polecats already use beads redirect (`../../mayor/rig/.beads`)
- Mayor's beads are authoritative - polecats read from there
- Fresh branches ensure clean starting state
- Old branches are ephemeral (never pushed to origin)

### Files Changed
- `internal/polecat/manager.go`: Add/Recreate/CleanupStaleBranches
- `internal/git/git.go`: ListBranches helper
- `internal/cmd/polecat.go`: `gt polecat gc` command

### Commands Added
```
gt polecat gc <rig>           # Clean up stale branches
gt polecat gc <rig> --dry-run # Show what would be deleted
```

Implemented fresh unique branches per polecat run. Added gt polecat gc for cleanup.

Polecats should not bd sync on startup

Polecats all share the same beads database at the rig level. The refinery and mayor/witness manage syncing beads.

## Current Behavior
Polecat startup runs bd sync, causing:
- Contention when multiple polecats spawn simultaneously
- Unnecessary sync operations
- Potential race conditions

## Desired Behavior
- Polecats should NOT run bd sync on startup
- They read from the shared beads database
- Only refinery/witness/mayor sync beads

## Implementation
Remove bd sync from polecat spawn/startup sequence.

Witness Patrol Molecule

Create mol-witness-patrol molecule for witness heartbeat loop.

Similar to DeaconPatrolMolecule but for per-rig witness duties.

## Steps
1. inbox-check - Process witness mail
2. survey-workers - List polecats, check status
3. inspect-workers - Capture pane output, assess state
4. plugin-run - Execute plugins from <rig>/plugins/witness/
5. decide-actions - Determine nudges, escalations
6. execute-actions - Send nudges, process shutdowns
7. context-check - Check own context, handoff if needed
8. loop-or-exit - Continue or cycle

The plugin-run step enables user customization of the patrol loop.


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`


Beads as Universal Data Plane

## Vision

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

## New Bead Categories

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

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

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

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

## v1 Priority

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

Design: Plugin architecture (agents-as-plugins)

Plugin system where plugins are just additional agents with identities, mailboxes, and beads access. See docs/architecture.md Plugins section. No special framework - just directory conventions and mail-based invocation.


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
- Mayor checking what polecats are doing
- Witness verifying polecat progress
- Debug: "why isnt this polecat working?"
- Deacon patrol: track all agent states

mol-ready-work variants: safe vs aggressive

## Summary

Create two variants of mol-ready-work:

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

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

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

MVP Cutover: GGT replaces PGT for batch work

When this is closed, stop using town and start using gt.

## Acceptance Criteria

1. gt spawn assigns issue to polecat and starts session
2. gt spawn --epic spawns workers for all epic children
3. gt session manages tmux lifecycle
4. gt send / gt inbox work for mail
5. Refinery processes merge queue with semantic merges
6. Integration branches created and landed correctly
7. gt stop --all halts all sessions
8. One successful test batch completed end-to-end

## What Must Work

- Spawn polecat with issue assignment
- Spawn workers for epic children
- Session start/stop/attach
- Mail send/inbox/read
- Refinery merge loop (semantic)
- Integration branch → main landing
- Witness cleanup protocol
- Emergency stop

## What Can Be Deferred

- Doctor checks (use PGT)
- TUI dashboard
- Plugin system
- Federation
- Ephemeral rigs
- Detailed landing reports

## Test Plan

1. Create epic with 2 tasks, spawn 2 workers
2. Verify polecats get assigned and sessions start
3. Simulate task completion
4. Verify Refinery merges to integration
5. Verify landing to main
6. Verify cleanup

## Validation

Run one real batch implementing GGT issues using GGT.

## Note

No "swarm IDs" - just spawn workers for epic, let merge queue coordinate.

gt orphans: Find lost polecat work

Add a command to find orphaned commits that were never merged to main.

## Problem
Polecat work can get lost when:
- Session killed before merge
- Refinery fails to process
- Network issues during push

## Solution
Add `gt orphans` command that:
1. Uses `git fsck --unreachable` to find dangling commits
2. Filters to recent commits (default: 7 days, configurable)
3. Excludes stash/index entries (WIP on, index on)
4. Shows commit details and suggests recovery

## Usage
```
gt orphans              # Last 7 days
gt orphans --days=14    # Last 2 weeks
gt orphans --recover    # Interactive cherry-pick
```

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

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

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

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

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

This should be standard Gas Town rig configuration.

Auto-handoff: self-cycling with guaranteed work pickup

## Summary

A mechanism for agents to self-cycle: send handoff mail, request Deacon to kill the process, and automatically restart to pick up the work.

## Use Case

User says: `auto-handoff: gt-bug3`

The agent:
1. Sends handoff mail documenting current state
2. Requests Deacon to terminate the session
3. Deacon restarts the agent in background
4. New session picks up the handoff and continues working

When the user returns to terminal, the old session is gone but work continues in background. User can reattach.

## Key Requirements

- **Guaranteed pickup**: Something in the hook and/or handoff must ensure the new session picks up the work (not just a passive "check inbox")
- **Background execution**: Work continues without user presence
- **Reattachability**: User can reconnect to see progress

## Design Questions

1. Can molecules help coordinate this? (e.g., molecule binds the handoff + auto-restart)
2. What hook handles the pickup guarantee?
3. How does Deacon know to restart vs just kill?
4. How does user reattach to a background agent?

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.

rebase-main

Rebase against main to incorporate any changes.
Resolve conflicts if needed.

git fetch origin main
git rebase origin/main

If there are conflicts, resolve them carefully and continue the rebase.

Depends: self-review, verify-tests


Keepalive signal from bd/gt commands

Every bd and gt command should touch a keepalive file to signal 'agent is alive/working'.

## Implementation

Touch `<workspace>/.gastown/keepalive.json`:
```json
{"last_command": "bd show gt-99m", "timestamp": "2025-12-18T13:45:00Z"}
```

## Usage by Daemon

- Fresh (< 2 min) → agent is working, skip heartbeat
- Stale (2-5 min) → might be thinking, gentle poke
- Very stale (> 5 min) → likely idle, safe to interrupt

## Benefits

- Zero cost (just file I/O)
- Works during long tool calls
- Doesn't require agent cooperation
- Foundation for smarter backoff strategies


stderr suppression hides critical errors

Multiple files set cmd.Stderr = nil:
- prime.go
- up.go
- orphans.go
- daemon.go

This hides git errors and command failures.

Should capture stderr for debugging and log when errors occur,
rather than suppressing entirely.

gt sling should accept raw issues, not just molecules

Currently gt sling only works with molecules. When you try to sling a raw issue:

  gt sling gt-9uy0 gastown/crew/max
  Error: invalid thing: issue not found

Options:
1. Auto-wrap issues in a simple work molecule (mol-issue-work?)
2. Create a minimal 'envelope' molecule on the fly
3. Just pin the issue directly without a molecule wrapper

The friction of needing a molecule for every piece of work discourages using the sling mechanism for ad-hoc tasks.

Related: crew workers often want to pick up an issue without formal molecule choreography.

gt spawn should auto-start refinery/witness if not running

When spawning a polecat, the infrastructure (refinery, witness) should already be running.

## Current Behavior
spawn.go only:1. Assigns issue to polecat2. Sends work mail3. Starts polecat session

The refinery and witness must be started separately.

## Expected Behavior (per user feedback)
When spawning a polecat, if the rig's refinery or witness is not running, auto-start them.

## Options

### Option A: spawn auto-starts infrastructure
Check if refinery/witness running before spawn, start if not.

### Option B: gt swarm start <rig> command
Explicit command that:
1. Starts refinery
2. Starts witness
3. Optionally spawns polecats on bd ready issues

### Option C: gt rig start <rig>
Similar to Option B but as rig lifecycle command.

## Problem

`gt polecat add gastown Nux` fails if the branch `polecat/Nux` already exists.

## Current Behavior

```

```

## Expected Behavior

Should either:
1. Reuse the existing branch
2. Or prompt to delete/recreate
3. Or auto-suffix: polecat/Nux-2

## Context

Branch may exist from previous polecat that was removed but branch wasn't cleaned up.


Human escalation: notify overseer when self-heal fails

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

**Implementation**: Config in town.json or similar:
```yaml
escalation:
  contact: steve@example.com  # or slack webhook
  triggers:
    - daemon_cant_restart
    - session_missing_5min
```

**Trigger points**:
- Go daemon can't restart a session after N attempts
- Agent detects it's stuck and can't recover
- Witness can't reach polecat

**Mechanism**:
- Simple: `gt mail send --human` already exists
- Enhanced: email/slack via external script

**Weight**: Small config + one code path in daemon
**Value**: High for unattended operation - human gets notified instead of silent failure


gt nudge should accept partial/fuzzy session names

Currently gt nudge requires the exact tmux session name (e.g., gt-gastown-crew-max). Should be more forgiving:

1. Accept partial matches when unambiguous (e.g., 'max' → gt-gastown-crew-max)
2. Accept shorthand like 'gastown/max' or 'crew/max'
3. Show helpful error with suggestions when ambiguous

Examples that should work:
- gt nudge max '...' → matches gt-gastown-crew-max
- gt nudge gastown/max '...' → matches gt-gastown-crew-max
- gt nudge beads-dave '...' → matches gt-beads-crew-dave

detectSender() doesn't recognize crew workers

## Problem

detectSender() in internal/cmd/mail.go only checks for /polecats/ directories. Crew workers in /crew/<name>/ fall through to the default 'mayor/', so:

- gt mail send sets the wrong From address

## Fix

Add crew worker detection before the /polecats/ check:

if strings.Contains(cwd, "/crew/") {
    parts := strings.Split(cwd, "/crew/")
    ...
    return fmt.Sprintf("%s/crew/%s", rigName, crewMember)
