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. assert tifffile.__version__ == '2026.7.31'
  2. tifffile.imwrite writes 2D uint8 image arrays to TIFF format and tifffile.imread recovers identical array shape, dtype, and pixel values
  3. tifffile.imwrite writes 3D RGB image arrays and tifffile.imread preserves dimensions and multi-channel pixel data
  4. tifffile.imwrite supports uint16 and float32 numeric data types with lossless roundtrip verification
  5. tifffile.TiffFile opens TIFF streams in a context manager and provides access to pages, series, shape, and dtype metadata
  6. tifffile.TiffFile raises tifffile.TiffFileError when attempting to read corrupted or non-TIFF binary data
