The Grain of Before

The memory is an explicitly programmed grain state, not evidence of autobiographical memory in physical materials. Measurements establish directional bias but do not establish visible ridge splitting, perceptual readability, or expanded human expression; no images were inspected or user evaluation supplied. Only two histories with one seed and default parameters were tested. Waiting, forgetting, the learning-zero control, and robustness across other gestures remain untested. Exact reproduction demonstrates determinism for these executions, not broader validity. The 24-by-18 grid and rounded field values limit spatial detail, and grain cannot uniquely recover an event history. No peer comparison or runtime and byte-budget measurements were provided. No earlier execution errors were reported.
