+# Story 175: Add Rust test coverage reporting with cargo-llvm-cov
+
+## User Story
+
+As a project owner, I want Rust test coverage reports generated and stored in a standard location, so that agents and QA can track whether stories improve or degrade test coverage.
+
+## Acceptance Criteria
+
+- [ ] cargo-llvm-cov is installed and runnable in the project
+- [ ] Running cargo nextest via llvm-cov produces coverage output in JSON and lcov formats
+- [ ] Coverage reports are written to .story_kit/coverage/server.json and .story_kit/coverage/server.lcov
+- [ ] STACK.md quality gates section is updated to document the coverage command
+- [ ] .gitignore excludes .story_kit/coverage/ output files
+
+## Out of Scope
+
+- TBD
