"""Agent App sandbox file-system inspector (read-only).
Exposes the PRD "rc1-like sandbox file system, downloadable not editable" view
for an Agent App conversation: list a directory, preview a file, or download a
file from the conversation's shell-layer workspace. The API never touches
shellctl directly — it resolves the conversation's sandbox ``session_id`` from
the stored session snapshot and proxies to the agent backend's read-only
workspace endpoints.
