Caret-based full-line completion samples extracted from permissively licensed C# repositories with csharp-dataset-prepare. Each sample is an exact editor position: leftcontext ends at the caret, targettext is the rest of the physical line (no newline), rightcontext follows it. Original source is reconstructable from offsets; every row carries repositoryid, revision, relativepath and license for attribution. Splits are assigned per repository group (forks/near-copies together); cross-repository duplicate files are kept once. No code was built or executed. See the builder repository for the data contract, leakage policy and benchmarks. For every sample the builder removes the hidden target…
