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.

Contract
- decodedMap returns a DecodedSourceMap object with decoded 2D mappings array from a TraceMap initialized with encoded VLQ string
- decodedMap preserves source map metadata including version, file, sources, sourcesContent, names, and sourceRoot
- decodedMap correctly decodes 1-segment, 4-segment, and 5-segment mapping tokens
- decodedMap works with TraceMap initialized from a JSON string or an already-decoded source map
- decodedMap output is a plain object serializable with JSON.stringify and compatible with standard source map consumers
- decodedMap preserves ignoreList when present in the source map
