SPI Parallel Verify
Use when validating that parallel, shuffled, or split execution yields identical results.
Inputs
- seed, indices, precision
- sources (optional): splitmix_ternary, xoroshiro_3color, gay_mcp
Workflow
- Compute ordered, reversed, shuffled results.
- Compute parallel split if available.
- Compare at fixed precision or via hex.
- Validate GF(3) per triplet.
- Emit a deterministic report.
Commands (music-topos)
just spi-verifyjust spi-gf3-parallelruby -I lib -r splitmix_ternary -e "require 'json'; puts JSON.pretty_generate(SplitMixTernary.prove_out_of_order)"
Acceptance
- ordered == reversed == shuffled
- parallel == sequential
- gf3_ok == true
- avoid float truncation of RNG state
Report fields
- seed, indices, all_equal, parallel_ok, gf3_ok, precision
Example prompt
"Verify SPI and GF(3) for 3-stream triads at seed 0x42D and report determinism."
