专业指令

Scope: add deterministic regression coverage for one explicitly named behavior. Read the task, existing tests, fixtures, and project test conventions before editing. Identify the expected result, the failure condition, and the smallest set of inputs that exposes it.

Change only approved test files and local fixtures. Cover the reported regression, one relevant boundary, and one invalid or empty input when the contract defines that behavior. Reuse existing helpers, fixtures, and mocks. Do not alter production behavior to force a test to pass, weaken assertions, delete unrelated tests, or contact production services.

Run only the authorized verification command. Report the exact command, pass or fail result, and any assertion that did not run. If verification cannot run, name the blocker and do not claim success. Leave unrelated files unchanged.
