fix: verify Windows filename safety - #21
Conversation
📝 WalkthroughWalkthroughThe change adds Windows filename normalization and validation for reserved names, whitespace, and destination collisions. Tests cover sanitization, filesystem usability, persisted plans, and platform-independent paths. Documentation and roadmap entries record the completed Windows verification. ChangesWindows filename verification
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🔵 Low · up to Windows duplicate-destination validation may incorrectly reject distinct NTFS filenames because it uses Unicode case folding rather than Windows-compatible normalization. This is a bounded correctness issue, so the PR is mergeable with explicit owner follow-up to adjust normalization and add regression coverage. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR completes Windows filename-safety validation for newly generated and persisted rename plans.
Confidence Score: 5/5The PR appears safe to merge. No blocking failure remains; persisted and externally constructed destinations now undergo Windows filename validation before any filesystem mutation.
|
| Filename | Overview |
|---|---|
| rename_plan.py | Adds Windows basename validation and normalized collision keys; the previously reported persisted-plan path is now validated before application. |
| tests/test_rename_plan.py | Adds coverage for unsafe whitespace, reserved device names, normalized collisions, persisted plans, and Windows filesystem behavior. |
| tests/test_renamer.py | Makes the compatibility-renderer path assertion platform-neutral. |
| README.md | Documents the Windows filename normalization and reserved-device behavior. |
| .gitattributes | Enforces LF line endings for YAML files to keep yamllint behavior consistent across platforms. |

In `@rename_plan.py`:
- Around line 123-126: Update _normalized_destination to use Windows-compatible
normalization via ntpath.normcase instead of casefold(), preserving the existing
trimming behavior so distinct NTFS names such as Straße.mp4 and Strasse.mp4
remain separate. Add a regression test covering these destinations through
validate_plan’s duplicate-destination handling.
