Link Existing's Browse did nothing: GET /api/filesystem/browse answered 403
"No filesystem browse roots are available".
Two rules were fighting. /root is a default blocked tree in the attachment
guard, and Codeman running as root — containers, plenty of servers — makes
homedir() exactly /root, so the picker's own allowlisted Home root was blocked;
the other candidates live under it or do not exist. The root list came out
empty and there was nothing the user could open.
The blocked trees exist to keep ~/.ssh and friends out of reach, not to seal off
the user's own home. Only trees that would swallow a configured root whole are
dropped now: /root goes when Home is it (or sits inside it), /etc holds no
configured root and is untouched. Secrets stay protected — isSensitivePath
independently matches .ssh/, .env and credentials* at any depth, and it is what
the directory probe asks about.
⚠️ Navigation must reuse the same narrowed list the roots were chosen with.
Handing the raw trees downstream admits a root and then refuses every path
inside it, which reads as a picker that opens and does nothing.
