E.4.DPF:5.7 - Framework-evolution slice

A new controlled-environment study changes the admissible nutrient range used only by HC.NutrientMonitoring. Because this example selected a broad, refreshable G.2 pack, first revise that pack and preserve the displaced source reading. Use E.4.PFR to identify the nutrient pattern, its source-reuse relation, and its dependent examples as the affected set; use E.21 to evaluate the revised pattern body; use E.23 for repeated improvement of that pattern edition; and use G.11 for currentness, telemetry, and deprecation or supersession of exposed editions. Unaffected climate-control and harvest-feedback patterns remain current. E.4.PFAD stays closed while framework family, pattern split, relation structure, publication-form, presentation-carrier or access-route architecture, and dependency boundary remain unchanged; a change to one of those decisions makes PFAD current again.
