# 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
