  "_comment": "Importable meter envelope for CUSTOM meters — for file-based import via the Mediation UI. CRITICAL DIFFERENCES from the internal meter JSON (used by create_meter): (1) tasks are nested inside versions[], not at the top level; (2) schemas[] is embedded inline; (3) latestVersion is required and must not be empty; (4) each task requires uniqueName (single letter a/b/c...) and internalName (null); (5) predecessors use [{\"id\": \"uuid\"}] objects — NOT plain strings; (6) schemaId and storeId must be the entity NAME string — NOT the numeric ID.",
