feat(parser): C# language pack via optional extra - #63
Merged
Conversation
graphlm[csharp] pulls tree-sitter-c-sharp; the resolver lives in-tree (graphlm/parsers/csharp.py). using static Ns.Type and using Alias = Type resolve to Ns/Type.cs. A namespace using Ns; resolves only when exactly one scanned file lives in that namespace directory — two or more files are dropped (GRAPH_DIFF fan-out, same reason as Java wildcards) and mark the list not exhaustive (ADR-007). using System; misses are third-party, not partial. Without the extra: zero C# edges, one log line, never a crash. graphlm[all] now includes csharp. Verified: csharp_project exact edge set (4 edges + cycle); pytest 732 passed / 5 skipped with extras; mypy clean. Co-authored-by: Grok 4.6 <noreply@x.ai>

C#
usingnames a namespace, not a file. Fan-out to every file in the namespace would churn every importer's edge set when a type is added. Unique-or-drop is the honest v1; the model still infers the rest.Verification
