+# Test Environment Verification (bf-1irl)
+
+## Date
+2026-07-02
+
+## Summary
+Verified that the Rust toolchain, cargo, and all test dependencies are properly installed and configured for the claude-print project.
+
+## Findings
+
+### Toolchain Status
+- **cargo**: 1.95.0 (f2d3ce0bd 2026-03-21) ✓
+- **rustc**: 1.95.0 (59807616e 2026-04-14) ✓
+- **rust-version required**: 1.82 (satisfied by 1.95.0) ✓
+
+### Build Dependencies
+- **build-essential**: Installed ✓
+- **libssl-dev**: Installed ✓
+- **pkg-config**: Installed ✓
+
+### Cargo Workspace
+- **Workspace members**: 2 (main + test-fixtures/mock-claude)
+- **Total packages**: 84
+- **All dependencies**: Resolvable and downloadable ✓
+
+### Test Results
+- **Library tests**: 90 passed, 0 failed
+- **Test compilation**: Successful (with minor warnings about unused imports)
+- **Integration tests**: Available in tests/integration/scenarios.rs
+
+### Notes
+- No dev-dependencies section in Cargo.toml (all dependencies are runtime deps)
+- cargo-nextest is not installed (not required, standard cargo test works fine)
+- Minor compiler warnings present (unused imports) but do not affect test functionality
+- cargo-remote wrapper detected, falling back to local execution due to uncommitted changes
+
+## Conclusion
+The test environment is fully functional with all required dependencies available.
