Connected concepts

Limits and interpretation

  • Previous accepted major-step input with explicit initial output; pure trial reads and transactional accepted-step commits. Rejected steps do not advance memory.
  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

Reference basis

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.

Implementation sources

This reference follows the public interface and locally verified numerical checks for an upcoming release.
