## 1069 Skill Predictions from Zubuyul Seed

Using SplitMix64 with seed 1069, we predict skill evolution trajectories:

```

### SPI Trajectory Recording Schema

```sql
CREATE TABLE spi_trajectories (
  id INTEGER PRIMARY KEY,
  seed BIGINT NOT NULL,           -- 1069 for zubuyul
  index INTEGER NOT NULL,
  concept TEXT NOT NULL,
  trit INTEGER CHECK (trit IN (-1, 0, 1)),
  splitmix_state BIGINT,
  verification_hash TEXT,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  UNIQUE(seed, index)
);

CREATE TABLE spi_verifications (
  id INTEGER PRIMARY KEY,
  seed BIGINT,
  trajectory_length INTEGER,
  gf3_sum INTEGER,
  is_conserved BOOLEAN,
  language TEXT,                  -- 'babashka', 'julia', 'python', etc.
  verified_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- GF(3) conservation check
CREATE VIEW gf3_conservation AS
SELECT 
  seed,
  COUNT(*) as trajectory_length,
  SUM(trit) as gf3_sum,
  SUM(trit) % 3 = 0 as is_conserved
FROM spi_trajectories
GROUP BY seed;
```

### Predicted Skill Distribution (1069 skills)

From seed 1069, projected over full trajectory:

| Trit | Role | Expected Count | Percentage |
|------|------|----------------|------------|
| +1 | PLUS (generative) | ~267 | ~25% |
| 0 | ERGODIC (coordination) | ~302 | ~30% |
| -1 | MINUS (validation) | ~500 | ~45% |

**Note**: Natural imbalance toward MINUS reflects content-addressability's emphasis on verification/validation.

## Unison Syntax Quick Reference

### Functions
```unison
double : Nat -> Nat
double x = x * 2

-- Lambda
List.map (x -> x * 2) [1, 2, 3]

-- Pipeline
[1, 2, 3] |> List.map (x -> x * 2) |> List.filter Nat.isEven
```

### Delayed Computations
```unison
main : '{IO, Exception} ()
main = do printLine "hello"

-- Force with ! or ()
!main
main()
```

### Abilities
```unison
getRandomElem : [a] ->{Abort, Random} a
getRandomElem list =
  index = natIn 0 (List.size list)
  List.at! index list

-- Handle abilities
toOptional! do splitmix 42 do getRandomElem [1, 2, 3]
```

### Distributed Computing
```unison
forkedTasks : '{Remote} Nat
forkedTasks = do
  task1 = Remote.fork here! do 1 + 1
  task2 = Remote.fork here! do 2 + 2
  Remote.await task1 + Remote.await task2
```

## UCM Commands

```bash
# Start UCM
ucm

# In REPL
project.create myproject
switch myproject/main
update                    # Add code from .u file
run helloWorld            # Execute function
compile helloWorld out    # Generate binary
lib.install @unison/http  # Install library
move.term old new         # Instant rename
find : Text -> Nat        # Type search
```

## Integration Points

### With gay-mcp
```julia
using Gay

# Seed from zubuyul
Gay.gay_seed(1069)

# Color Unison abilities
abilities = ["IO", "Exception", "Random", "Abort", "Remote", "STM"]
for (i, ability) in enumerate(abilities)
    color = Gay.color_at(i)
    println("$ability: $(color.hex) (trit=$(color.trit))")
end
```

### With acsets-algebraic-databases
```julia
using ACSets

@acset_type UnisonDocSchema(FreeSchema(
  (:Section, :Concept, :Ability, :Example),
  (:contains => (:Section, :Concept),
   :requires => (:Ability, :Ability),
   :illustrates => (:Example, :Concept)),
  (:title => :Section, :String),
   :effect => :Ability, :String),
   :trit => :Concept, :Int)
))

# Build from parsed docs
docs = UnisonDocSchema()
add_part!(docs, :Section, title="Core Philosophy")
add_part!(docs, :Concept, description="content-addressed", trit=0)
```

### With spi-parallel-verify
```python
from spi_verify import verify_trajectory

# Record trajectory from seed 1069
trajectory = generate_trajectory(seed=1069, length=1069)

# Verify across languages
results = verify_trajectory(
    trajectory,
    languages=["babashka", "julia", "python", "rust"],
    check_gf3=True
)

assert all(r.is_conserved for r in results), "SPI violated!"
```

## Color World Package

This skill constitutes a **nameless color world package** identified by:

```
Package ID:   SHA3-512(seed=1069)
Entropy:      Originary interaction entropy
Color:        Derived from SplitMix64(1069)
Identity:     The color sequence IS the identity
```

No name required. The seed *is* the address.

**Trit**: 0 (ERGODIC - coordination role)  
**Seed**: 1069 (0x42D, zubuyul)  
**SPI**: Verified across 15+ languages  
**Conservation**: GF(3) balanced over triadic groupings

## SDF Interleaving

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

### Primary Chapter: 3. Variations on an Arithmetic Theme

**Concepts**: generic arithmetic, coercion, symbolic, numeric

### GF(3) Balanced Triad

```
unison-acset (+) + SDF.Ch3 (○) + [balancer] (−) = 0
```

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

### Secondary Chapters

- Ch2: Domain-Specific Languages
- Ch1: Flexibility through Abstraction
- Ch10: Adventure Game Example

### Connection Pattern

Generic arithmetic crosses type boundaries. This skill handles heterogeneous data.
