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
- generatedPositionFor maps original source, 1-based line, and 0-based column to generated line and column
- generatedPositionFor returns null line and column when the queried position or source is not mapped
- generatedPositionFor with GREATEST_LOWER_BOUND finds the generated position of the nearest mapping at or before the queried column
- generatedPositionFor with LEAST_UPPER_BOUND finds the generated position of the nearest mapping at or after the queried column
- generatedPositionFor correctly resolves positions across multiple source files in a single TraceMap
