This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. Setting TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK to '1' fails to bypass gencode version validation because the check strictly requires 'true', continuing to raise VersionError on newer gencode
  2. Setting TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK to case-insensitive 'true' disables gencode validation and allows newer gencode to load without VersionError
  3. Importing gencode generated by a newer protoc version raises VersionError identifying the version mismatch
  4. Importing gencode generated by an older protoc version succeeds without error on a newer runtime
  5. Dynamic mutations to TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK take effect immediately on subsequent validation calls rather than caching on module import
