# Universal CapTP Derivation Skill

Traces capability derivation chains through 3×3 expert poset with GF(3) conservation.

## Core Principle

> **A capability IS the (seed, index) tuple. Expertise IS the trit alignment.**

## 3×3 Expert Poset Structure

| Layer | Validator (-1) | Coordinator (0) | Generator (+1) | Domain |
|-------|----------------|-----------------|----------------|--------|
| 1 | Jules Hedges | John Baez | Fabrizio Genovese | categorical-games |
| 2 | David Egolf | Mike Shulman | sarahzrf | sheaf-theory |
| 3 | Betweenness | Mantissa | ModalNoah | neural-categorical |

## Derivation Chains

```
capability(-1) → vat(0) → invoke(+1)     [spawn-lifecycle]
membrane(-1)   → netlayer(0) → lambda(+1) [invoke-path]
handoff(-1)    → syrup(0) → sturdy_ref(+1) [transfer-path]
revoke(-1)     → promise(0) → goblin(+1)   [revoke-path]
```

## Superposition States

Each capability exists in superposition across expert domains:
- **generator-dominant**: Red channel highest (trit=+1)
- **coordinator-dominant**: Green channel highest (trit=0)
- **validator-dominant**: Blue channel highest (trit=-1)
- **superposed**: Balanced RGB

## GF(3) Conservation

```
Term Σ + Expert Σ ≡ 0 (mod 3)
```

Current state: **COHERENT** (residue = 0)

## Commands

```bash
# Trace derivation chains
python3 -c "import duckdb; c=duckdb.connect('culture_evolution.duckdb'); print(c.execute('SELECT * FROM derivation_chains').df())"

# View expert triads
python3 -c "import duckdb; c=duckdb.connect('culture_evolution.duckdb'); print(c.execute('SELECT * FROM expert_triads').df())"

# Query NOW superposition
python3 -c "import duckdb; c=duckdb.connect('culture_evolution.duckdb'); print(c.execute('SELECT * FROM now_superposition').df())"

# Universal skill derivation
python3 -c "import duckdb; c=duckdb.connect('culture_evolution.duckdb'); print(c.execute('SELECT * FROM universal_skill_derivation LIMIT 20').df())"
```

## Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

### Graph Theory
- **networkx** [○] via bicomodule
  - Universal graph hub

### Bibliography References

- `general`: 734 citations in bib.duckdb



## SDF Interleaving

This skill connects to **Software Design for Flexibility** (Hanson & Sussman, 2021):

### Primary Chapter: 6. Layering

**Concepts**: layered data, metadata, provenance, units

### GF(3) Balanced Triad

```
universal-captp-derivation (+) + SDF.Ch6 (+) + [balancer] (+) = 0
```

**Skill Trit**: 1 (PLUS - generation)

### Secondary Chapters

- Ch10: Adventure Game Example
- Ch1: Flexibility through Abstraction

### Connection Pattern

Layering adds metadata. This skill tracks provenance or annotations.
## Cat# Integration

This skill maps to **Cat# = Comod(P)** as a bicomodule in the equipment structure:

```
Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826
```

### GF(3) Naturality

The skill participates in triads satisfying:
```
(-1) + (0) + (+1) ≡ 0 (mod 3)
```

This ensures compositional coherence in the Cat# equipment structure.
