+# Story 171: Persist test results to story files
+
+## User Story
+
+As a project owner, I want test results written to the story markdown file when record_tests is called, so that there's a durable paper trail that survives server restarts.
+
+## Acceptance Criteria
+
+- [ ] record_tests appends or updates a Test Results section in the story markdown file
+- [ ] Test results section shows test name, status (pass/fail), and details for each recorded test
+- [ ] Results persist across server restarts by being read back from the file on load
+- [ ] ensure_acceptance reads from the persisted file data, not just in-memory state
+
+## Out of Scope
+
+- TBD
