bwrap processes mount args in order. When the SDK binary lives under $HOME (e.g. ~/.config/Claude/claude-code-vm/), the --ro-bind of its parent directory was added before --dir $HOME. The later --dir wiped out the bind, causing "bwrap: execvp ... No such file or directory". Move --dir $HOME first so the home skeleton exists before subdirectory bind mounts are layered on top of it.

Hey! Good catch on the bwrap mount ordering. The diagnosis is spot on. bwrap processes args sequentially, so --dir $HOME after --ro-bind sdkDir wipes the bind mount when the SDK path lives under $HOME. The reorder is the correct fix.
One thing to clean up before merging: the diff includes ~80 lines of whitespace-only changes in resolveSubpath, buildSpawnEnv, and buildMountMap. Those functions are functionally identical before and after. The extra churn makes the diff harder to review and pollutes git blame for future contributors trying to trace actual logic changes.
Can you resubmit with only the functional reorder? The easiest way is usually to reset and re-apply just the lines you intended to change. Something like:
git diff HEAD~1 --statto confirm which files changed- Reset and selectively stage only the reorder hunks
- Force-push the cleaned branch
The actual fix is ~15 lines and reads cleanly on its own. I'd like to keep the diff tight so it's obvious what changed and why.
Once the whitespace noise is removed, this is good to merge.
