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. SourceMapConsumer parses raw source map and resolves original position for a generated coordinate
  2. SourceMapConsumer resolves original position with GREATEST_LOWER_BOUND and LEAST_UPPER_BOUND bias options
  3. SourceMapConsumer resolves generated position for an original source line and column
  4. SourceMapConsumer returns all generated positions matching an original source line
  5. SourceMapConsumer retrieves embedded source content by file name
  6. SourceMapConsumer iterates over mappings in GENERATED_ORDER and ORIGINAL_ORDER
  7. SourceMapConsumer checks whether contents are embedded for all source files
