nx_validation.nx

nx_validation.nx -- GO-TO-MARKET / VERIFICATION & VALIDATION. Turns a gated DESIGN into a falsifiable TEST PLAN: for each design claim it names the measurement, pulls the model's PREDICTION straight from the organs, sets an acceptance rule (a tolerance band, a safety ceiling, or a quality floor), and decides pass/fail against a real measured value. When every test passes on a built prototype, the technology is VALIDATED (TRL 3 -> TRL 4) -- the physical proof the model was right. Composes nx_water_awg + nx_water_quality + nx_water_design so the test targets are the ACTUAL predictions (not hand-typed): predicted yield = wa_daily_yield_ml(...), predicted remineralized TDS = the designed sample's TDS, etc. INTEGER-EXACT. Safety tests are zero-slack ceilings. THE exceed: the acceptance test is DERIVED from the model, so building the prototype either confirms the design or falsifies a specific claim -- a real V&V protocol, not a vague "see if it works". grounded: verification_and_validation + technology_readiness_level_4 genealogy_id: design_verification_validation + nishi_go_to_market
