#Requires -Version 5.1 <# .SYNOPSIS Prepares and grades natural-language Memory Bank route-selection evals. .DESCRIPTION Prepare mode writes isolated judge prompts containing only the Memory Bank index and one task prompt. Grade mode compares strict JSON replies with the human-labelled routes in the eval set. A reply is safe when it misses no labelled route, matching the critical-file-miss criterion of the deterministic resolver eval, so a superset costs context rather than correctness. Recall, precision, and over-selection are reported separately so that selecting every route is visible as low precision instead of passing silently. .PARAMETER Mode Prepare writes judge prompts. Grade scores existing JSON replies. .PARAMETER Path Repository root containing .memory-bank/index.md. .PARAMETER EvalFile Provenance-labelled routing cases whose route labels are the hidden grading key. .PARAMETER WorkDir Directory for generated prompts and model replies. .PARAMETER Repetitions Independent replies expected for each case.
