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. FileInfo instantiates with name, unknown type, zero size, empty rawModifiedAt, and undefined optional fields
  2. FileInfo boolean getters isFile, isDirectory, and isSymbolicLink reflect FileType enum values
  3. FileInfo date getter and setter provide backwards compatibility with rawModifiedAt
  4. FileInfo.UnixPermission defines Read, Write, and Execute bitmask values (4, 2, 1)
  5. parseList populates FileInfo with Unix permissions, owner, group, and size from Unix listing format
  6. parseList populates FileInfo with parsed modifiedAt Date, size, and uniqueID from MLSD listing format
