fix: downloads are marked and keep their extension; Explorer files are refused

2026-10-01T09:47:39Z

The desktop app writes the Mark-of-the-Web on each file it saves on Windows, as a browser does. Bidirectional controls are reserved characters in a saved name (portable-name.js and paths.sanitize_for_download, and again in the main process), so a name cannot display one extension and carry another. The node refuses uploads of files Windows Explorer acts on by itself: desktop.ini, .lnk, .url, .scf, .library-ms, .searchConnector-ms (F-19). Co-Authored-By: Claude Opus 5.5

fix(node): an upload never replaces a file, nor shares a part with another

2026-10-01T07:57:11Z

A name an upload in flight will take is reserved; each upload writes its own `name..part`; the finished file is published by a hard link, which refuses an existing target, and takes the next free name if one appeared meanwhile — the last ack names it. Two members sending one name at once wrote one part and published it twice; a file copied in during an upload was replaced (F-09). Co-Authored-By: Claude Opus 5.5

refactor(node): move uploads out of webrtc_server

2026-09-24T14:45:38Z

UploadMixin in transport/webrtc/upload_handlers.py, with the upload cap; _upload_chunk moved unchanged, _append_chunk joins webrtc/disk.py. Co-Authored-By: Claude Opus 5.5
