本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。 MIT-0

契约

  1. pooch.create initializes a Pooch instance with base URL, cache directory, and file hash registry
  2. pooch.Pooch.get_url formats full download URLs for registered filenames
  3. pooch.Pooch.is_available verifies remote file availability via HTTP HEAD checks and raises ValueError if the file is not in registry
  4. pooch.Pooch.fetch downloads and validates remote files against registered checksums, returning local cache file paths
  5. pooch.Pooch.fetch reuses cached local files on subsequent calls without making additional network requests
  6. pooch.Pooch.fetch unpacks gzip archives when passed a pooch.Decompress processor
  7. pooch.retrieve downloads and validates single files directly to custom paths with SHA256 checksum verification
  8. pooch.retrieve raises ValueError when the downloaded content does not match the expected known_hash
  9. pooch.file_hash computes cryptographic SHA256 checksums of local files
