From 68b6f7f45c577d9883f2b4ec336a40ad0c91cb7f Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" <41898282+github-actions[bot]@users.noreply.github.com> Date: Thu, 13 Aug 2026 03:26:19 +0000 Subject: [PATCH 1/2] test: cover C# preprocessor ERROR-node and malformed-declaration reason branches Adds tests for previously-untested branches in getComplexityReasonFromErrorNode (if/while/for/foreach/logical-operator/ternary/try) and getComplexityReasonFromMalformedDeclaration (ternary/logical-operator), raising csharpAnalyzer.ts branch coverage from 78.32% to 87.33%.
