fix(file): strip Windows verbatim prefix from /api/fs/browse paths#453
Merged
Conversation
fs::canonicalize returns extended-length (verbatim) paths on Windows (\\?\C:\DEV), which the endpoint serialized verbatim into current_path, parent_path and item paths. The WebUI stored that string as the conversation workspace, breaking Claude Code spawning (cmd.exe shims reject verbatim working directories) and splitting the same directory into two project-list entries. Strip \\?\ and \\?\UNC\ prefixes at the response boundary; sandbox checks keep comparing canonical (verbatim) forms internally. Fixes iOfficeAI/AionUi#3191

Problem
iOfficeAI/AionUi#3191 — on Windows, selecting a directory in the WebUI picker stores paths like
\\?\C:\DEV\xxxxxas the conversation workspace. Claude Code then fails to connect (cmd.exe-based CLI shims reject verbatim working directories), and the same directory shows up as two different projects in the sidebar (C:\DEV\xxxxxfrom old sessions vs\\?\C:\DEV\xxxxxfrom new ones).Root cause
The
/api/fs/browseendpoint (added in #235, replacing the legacy Express implementation in AionUi) resolves paths withfs::canonicalize, which on Windows returns extended-length (verbatim) paths —\\?\C:\DEV. Those strings were serialized verbatim intocurrent_path,parent_pathand every itempath. The legacy Express endpoint built paths with Node'spath.joinand never produced this form, so this is an M6-cutover regression.Fix
Strip
\\?\(and\\?\UNC\→\\) at the response-serialization boundary inbrowse.rs. Internal sandbox checks keep comparing canonical (verbatim) forms, so the allow-list semantics are unchanged.Tests
