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. new CSSStyleSheet() initializes an empty stylesheet with empty cssRules and null parentStyleSheet
  2. insertRule parses and inserts CSSStyleRule into cssRules and sets parentStyleSheet reference
  3. insertRule supports inserting CSSMediaRule at specific index maintaining rule order
  4. insertRule throws RangeError INDEX_SIZE_ERR when insert index is out of bounds or negative
  5. deleteRule removes rule at index and updates cssRules list
  6. deleteRule throws RangeError INDEX_SIZE_ERR when target index is out of bounds or negative
  7. toString serializes all rules in cssRules to newline-delimited CSS text
