Cross-Language Strong Parallelism Invariance Verification

Version: 1.0.0
Trit: -1 (Validator - verifies cross-language consistency)
Bundle: verification

Overview

Polyglot-SPI verifies that the SPI (Strong Parallelism Invariance) seed 0xf061ebbc2ca74d78 produces identical color sequences across all supported languages. This ensures deterministic parallel execution regardless of runtime.

The SPI Invariant

GAY_SEED = 0x598F318E2B9E884
splitmix64(GAY_SEED) → 0xf061ebbc2ca74d78 (index 0)

This value MUST be identical in:
- Julia (Gay.jl)
- Rust (gay-rs, tf-moose)
- Python (gay_spi.py)
- TypeScript (eg-walker)
- Clojure (spi.cljd)
- Haskell (GaySPI.hs)
- Go (gay-go)
- Zig (gay_spi_zig.zig)
- OCaml (gay_spi.ml)
- Unison (gay.u)
- Common Lisp (slime)
- Scheme (geiser-chicken)
- Babashka (gay_spi_sci.bb)

2. generate-verification-suite

Generate test files for a new language.

from polyglot_spi import generate_tests

generate_tests(
    language="kotlin",
    output_path="gay_spi.kt",
    seed=0x598F318E2B9E884,
    expected_values={
        0: 0xf061ebbc2ca74d78,

        9: 0xd726fcf3f1d357d5
    }
)

3. splitmix64-reference

Canonical SplitMix64 implementation for comparison.

def splitmix64(state: int) -> tuple[int, int]:
    """
    Reference SplitMix64 implementation.
    Returns (next_state, output_value).
    """
    state = (state + 0x9E3779B97F4A7C15) & 0xFFFFFFFFFFFFFFFF
    z = state
    z = ((z ^ (z >> 30)) * 0xBF58476D1CE4E5B9) & 0xFFFFFFFFFFFFFFFF
    z = ((z ^ (z >> 27)) * 0x94D049BB133111EB) & 0xFFFFFFFFFFFFFFFF
    return state, (z ^ (z >> 31)) & 0xFFFFFFFFFFFFFFFF

# Verify
GAY_SEED = 0x598F318E2B9E884
state, value = splitmix64(GAY_SEED)
assert value == 0xf061ebbc2ca74d78

4. color-sequence-verify

Verify full color sequences match across languages.

def verify_color_sequence(n: int = 100) -> bool:
    """
    Generate n colors in each language and compare.
    """
    reference = julia_generate_colors(n)

            if ref != actual:
                raise AssertionError(
                    f"Mismatch at index {i}: {lang} produced {actual}, expected {ref}"
                )
    
    return True

5. trit-sequence-verify

Verify GF(3) trit sequences are identical.

def verify_trit_sequence(n: int = 1000) -> bool:
    """
    Trits must sum to 0 mod 3 for every consecutive triple.
    """
    trits = generate_trits(n, seed=0xf061ebbc2ca74d78)
    
    for i in range(0, n - 2, 3):
        triple_sum = trits[i] + trits[i+1] + trits[i+2]
        if triple_sum % 3 != 0:
            raise AssertionError(f"GF(3) violation at index {i}")
    
    return True
