ProcessWire Page Edit Permission Missing Field‑Level Restriction

Desired field‑level edit control

Administrators need a role that can edit pages based on a template but should be prevented from modifying certain fields, such as internal metadata or hidden fields, while still allowing edits to other fields on the same page.

ProcessWire core grants edit permission at the template level, which makes all fields on a page editable for any user with that role. There is no built‑in setting to restrict individual fields, and administrators often resort to custom hooks or third‑party modules, which can introduce ordering issues and inconsistency.

The absence of a native mechanism forces site builders to evaluate trade‑offs between development effort, maintenance overhead, and potential data‑integrity risks when deciding how to protect sensitive fields.

Is there a core configuration option to enable field‑level edit restrictions? Can a hook be implemented reliably to lock fields without risking a race condition where the field is saved before the restriction runs? Are there any officially supported modules that provide field‑level permissions without requiring custom code?
