Defects in GitGalaxy's function call graph found by comparing it against a compiler or type-checker reference: pyan3 for Python, the TypeScript compiler's type checker (tests/tools/ts_callgraph.js) for TypeScript, and future references for other languages. The comparison runs as the Level 2 call-resolution gate (tests/tools/call_graph_resolution.py, graph-accuracy-audit.yml). Every issue it surfaces goes here: a wrong confident link, a link into a bodyless signature, a call the engine never extracts, a reference-tool gap. Also here are the PRs that add a language's reference or fix what it finds. Numbers quoted in these issues are against a reference, not ground truth. Check disagreements against source before claiming them (CLAUDE.md, "Comparative-correctness claims").
