  "about": "A rights receipt for an asset at a public URL: a2ally fetches the asset's bytes once, hashes them, and records the license signals those bytes carry — SPDX-License-Identifier markers, named license texts, and copyright lines — on a public receipt sealed to the ledger. Anyone can re-fetch the URL, re-hash the bytes and check the receipt against them.",
  "note": "A receipt records signals; it asserts no license and no verdict. Signals found do not grant any use, and no signals found does not mean an asset is unlicensed — it means only that these bytes carried none of the listed signals when fetched. Whether a use is permitted is a license question: check_license answers those.",
