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. SourceMapGenerator generates a v3 source map with mappings between generated and original positions
  2. SourceMapGenerator sets and embeds original source file content in sourcesContent
  3. SourceMapConsumer resolves original source, line, column, and symbol name from generated coordinates
  4. SourceMapConsumer resolves generated line and column coordinates from original positions
  5. SourceMapConsumer returns all generated positions corresponding to an original line
  6. SourceMapConsumer retrieves embedded original source content for a source identifier
  7. SourceMapConsumer iterates over all mappings in generated order
  8. SourceNode constructs composite source trees and produces generated code with an accurate source map
