  "description": "Anonymized sample of the record structure Keystone's Modular Index computes from. Every module passport that ingests into the registry contributes a record of this shape; the Modular Index (Standard, Pro, and Enterprise tiers) aggregates them into live industry benchmarks. Sample is illustrative, uses synthetic module identifiers, and does not represent any actual manufacturer, project, or transaction.",
