# Story 105: Test Coverage: io/shell.rs to 95%

## User Story

As a developer, I want io/shell.rs to have at least 95% test coverage, so that regressions in shell execution edge cases are caught early.

## Acceptance Criteria

- [ ] server/src/io/shell.rs reaches at least 95% line coverage (currently 84%, 15 lines missed)
- [ ] cargo clippy passes with no warnings
- [ ] cargo test passes with all tests green
- [ ] No changes to production code, only test code added

## Out of Scope

- TBD
