Module — 8 operations
ACF and Meta Box field groups, their fields, and their values — read and written through each plugin’s own API.
Needs: Advanced Custom Fields 5.9 or newer, Meta Box 5.3 or newer. Either, both, or neither. SiteHelm reports what it found rather than requiring it — an absent integration is a named refusal, not a broken call.
Values go through the field plugin’s own update function, never straight into post meta, so its formatting, serialisation and hooks all still run.
A group is read before a value is written, so the agent uses the site’s own field key rather than inventing one.
A read still asks WordPress for a capability against the object. There is no anonymous read anywhere in the surface.
