GPU Kernel Refactor Audit Progress

Review Summary

  • MersenneNumberDivisorByDivisorGpuTester: Confirmed kernel bindings, resource pooling, and filtering comments (including Montgomery data handling notes) remain intact with no functional changes.
  • MersenneNumberDivisorGpuTester: Verified the divisibility helper, candidate bootstrap, and divisor-cycle integration preserve their original comments and TODO guidance verbatim.
  • MersenneNumberIncrementalGpuTester: Checked that the incremental scan workflow, residue preparation comments, and TODO placeholders stayed untouched.
  • MersenneNumberLucasLehmerGpuTester: Audited the Lucas–Lehmer kernels, TODO annotations, and GPU limiter usage to ensure they were moved verbatim.
  • MersenneNumberOrderGpuTester: Confirmed residue automaton notes, TODO entries, and kernel selections remain unchanged.
  • MersenneNumberResidueGpuTester: Ensured the residue scan notes about cycle integration and buffer zeroing are still present without logic edits.
  • NttGpuMath: Reviewed cached kernel launchers and TODO lists to verify that only structural moves occurred.
  • Pow2OddPowerTable (PrimeOrderGpuHeuristics partial): Checked the odd-power ladder implementation and comments for exact retention.
  • PrimeOrderGpuHeuristics: Validated that partial factor kernels, capability overrides, and extensive TODO documentation remain verbatim.
  • ReadOnlyGpuUInt128: Confirmed helper constructors and implicit conversions were untouched by the refactor.

Next Step

Audit complete for the GPU namespace after the kernel extraction. No further classes remain pending in this pass.
