…is (B-0073) (#96) CodeQL was scanning .NET build artifacts under obj/ and bin/, including auto-generated xunit test entry points (`XunitAutoGeneratedEntry*.cs`). Findings on those files ask us to fix MSBuild's output, not source — wrong dependency direction. Empirically discovered 2026-04-28 while diagnosing why all 6 LFG PRs were BLOCKED with all-green CI: two open `cs/missed-ternary-operator` alerts on `obj/Release/net10.0/XunitAutoGenerated*.cs` were among 13 total Code Scanning alerts gating the LFG `code_quality:severity=all` ruleset on every PR. This config change drops 2 of 13 alerts via a single structural change with zero source-code risk. Composes with B-0073 (which covers the remaining 10 source alerts + 1 Scorecard meta-finding) and task #306 (the original 'Analyze (csharp) on PR' workflow-cost concern, which this helps reduce by limiting scan scope). Verification: next CodeQL run on main should report 11 (or fewer) open alerts instead of 13.

Pull request overview
Updates the repo’s CodeQL configuration to stop analyzing .NET build output directories that produce generated C# sources and false-positive alerts, unblocking CodeQL gating for PRs.
Changes:
- Extend
.github/codeql/codeql-config.ymlpaths-ignoreto exclude**/obj/**and**/bin/**. - Document the rationale for excluding these build artifact directories (generated xUnit scaffolding and compiler intermediates).
