Grid Search for Hyperparameter Optimization

Identity Notes & Concept Scope This is the general Cartesian-grid hyperparameter search, distinct from the maintained fairness reduction that enumerates Lagrange-multiplier-derived costs and constructs cost-sensitive classifier responses. It is also distinct from grid-based spatial path planning, independent random search, adaptive refinement of a grid, and halving-based resource allocation. Grid locations can be chosen in transformed coordinates; equal spacing in raw numerical values is not required by the Cartesian-product definition. No normalized identity match was found across all 442 pinned AIO labels/scoped synonyms and 259 preceding native IDs/names/aliases. Full-checkout fixed-string searches included ignored and hidden files in both worktree and main checkout, returning 26 lines in each checkout. These were prior candidate leads, source references and neighboring-method mentions, not existing records for these identities. Nine exact AIO CLASS nodes with synonyms and outgoing edges and six neighboring native mechanisms were inspected. Absence is bounded to this snapshot and semantic neighborhood.
