From cde25fa6cea8659fbb3dbd5756895d5781a12362 Mon Sep 17 00:00:00 2001 From: mao2009 <39354512+mao2009@users.noreply.github.com> Date: Mon, 24 Aug 2026 16:41:31 +0900 Subject: [PATCH] feat(analyzer): support per-diagnostic severity configuration via .editorconfig - Document Roslyn-standard .editorconfig severity configuration - Add ConsumerApp example project demonstrating severity settings - Update README.md and README_ja.md with Diagnostic Configuration section - Add test comments clarifying Roslyn's standard severity handling - Validate error/warning/none/suggestion/silent behavior - Confirm all 7 diagnostic IDs independently configurable Roslyn's built-in diagnostic severity mechanism (dotnet_diagnostic..severity) is sufficient for all current requirements. No custom severity API, Rule Set, or Preset is introduced. All 56 existing Analyzer tests pass. ConsumerApp integration tests confirm expected behavior.
