Selecting ~100 changed files in a WSL worktree and hitting Stage All did nothing: the files stayed unstaged and the operation reported a failure. Bulk stage/unstage/discard chunked pathspecs 100 at a time, a count picked against a raw argv. A WSL-routed write is not a raw argv -- it is folded into one login-shell command line that shell-quotes every pathspec, quotes the result again, and embeds it three times (one branch per guest shell), so the finished line runs ~3.4x the raw pathspec bytes. Realistic project paths blew past the 32767-character CreateProcess cap at 100 paths and wsl.exe refused to spawn, with nothing staged. Chunking now measures the finished command line through the real resolver, so the wrapper's quoting rules live in one place and native, WSL and SSH hosts each get the budget of the host that actually spawns. A pathspec too long to fit alone still ships alone rather than being dropped, and no chunk is ever emitted empty -- a pathspec-free `clean -ffdx` would have swept the whole worktree. The tracked-path listing behind that discard also fences the WSL login shell now. Its stdout was parsed NUL-delimited without a fence, so Ubuntu's interactive rc banner glued itself onto the first record: that path failed to match anything git reported and was treated as untracked, sending a tracked file to `git clean` instead of `git restore`. Not observing a path in ls-files output is not evidence the path is untracked. The Windows command-line cap and its libuv-aware length estimate move out of the WSL runner into src/shared/windows-command-line-budget.ts, shared by both callers.
