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. When ColorManagement.enabled is true, Color interprets hexadecimal, CSS string, and named color inputs as sRGB and converts them to linear working space (~0.216 for 0x808080), whereas numeric constructors assume linear space (~0.502).
  2. Color.getHex() converts working color space to sRGB, returning 0x808080 for hex-initialized colors but 0xbcbcbc for linear 0.502 numeric inputs.
  3. Setting ColorManagement.enabled to false bypasses color space conversions, causing new Color(0x808080).r to equal 128/255 (~0.502) and match numeric constructor values.
  4. Setting ColorManagement.workingColorSpace to SRGBColorSpace keeps sRGB hex inputs unchanged without linear transfer transformation.
