101* `managed-settings.json` must be a regular file (not a symlink), owned by root, and not group- or world-writable.
101* `managed-settings.json` must be a regular file (not a symlink), owned by root, readable by the users it configures, and not group- or world-writable.

104104A file that fails these checks is rejected: none of its settings are applied, the app treats the device as managed but unreadable, and local settings are also disabled until the file is fixed and the app is relaunched. The reason is logged to `main.log` in the app's logs directory, `~/.config/Claude/logs/` (or `~/.config/Claude-3p/logs/` once the app is running in 3P mode). Search the log for `managed-settings.json`. The same log names any key that fails schema validation.
No line in this hunk matches that.
