From 7c0af5489798fa6c78c2e29d4f823d62c15fdb97 Mon Sep 17 00:00:00 2001 From: zhangxiang Date: Sun, 2 Aug 2026 18:42:45 +0800 Subject: [PATCH] test(hooks): enhance focus-trap mutation score to 85.25% and finalize release acceptance - Increase use-focus-trap mutation score from 42.62% to 85.25% (exceeds 50% target) - Add 40 new test cases: focus cycling, Edge Cases, Focusable Elements Detection - Fix jsdom offsetParent limitation via prototype-level mock - Remove temporary debug file (__debug.test.tsx) - Update test-strategy-plan.md to v1.9 with mutation score and debt tracking - Update README.md with final acceptance progress - Quality gates: TypeScript 0 errors, ESLint 0 errors, 121 suites/1549 tests passed -
