test-case-review

Review existing test cases (legacy, others', AI) for coverage and executability: build a testable-points baseline, assess independently, revise in place with records. Not for: writing cases from scratch (test-case-writing), pipeline. 审查已有用例（存量/他人/AI 产出）的覆盖与可执行性：先建基准再独立评估，修订留审查记录。不用于：从零写用例、写时自审、流水线。
