"""
Which folder (possibly a subfolder of a shared root) is the Videos app's
entry point for a group. Same shape as test_apps_enabled_policy.py: a
signed operator instruction, per-group (unlike tmdb_config, which is
node-wide), stored via roster.py's group_settings table.

Specific to this one: a non-empty path must resolve to a real, readable
directory inside one of the group's own roots before a challenge is ever
issued — refusing a typo up front, the same way an empty apps set is
refused up front rather than round-tripped to the operator's browser.
