Blender GPU Runtime Reproducibility Under a Frozen Workload Contract

A frozen workload contract was validated for parity and control integrity. This report does not claim a completed V5 benchmark run.

Research · 2026-07-20 · FRS-2026-002

Question

Can a frozen Blender workload contract stay comparable when only historical V4 evidence exists and V5 has not been physically executed?

Scope

Frozen V5 contract controls, not a V5 physical run. Historical V4 evidence is not V5 execution evidence.

Historical V4 result only; not evidence of V5 execution

Method

The study checked artifact, scoring, and frozen-contract parity against the V5 contract. Physical V5 execution remains PENDING.

Limitations

  • V5 has not been physically executed and no V5 performance result is published.
  • No repeated runtime samples are asserted by this report.
  • Evidence covers one verified GPU configuration and cannot establish hardware-wide reproducibility.
  • Exact historical V4 runtime provenance remains insufficient.

Historical V4 evidence is not V5 execution evidence. This report publishes no V5 performance result.

What changed

FARPY treats V5 as a frozen contract, not a published performance result, until physical execution exists.
