WHEN two people or agents changed the same house design in parallel, starting from the same version, and both changes must be kept (like synchronising with a Revit central model). Three-way merge, element by element and field by field: a change made on one side goes through; the same field changed differently on both sides, or an element deleted on one side and modified on the other, is returned as a conflict, never silently overwritten. An opening stays on its own wall even if the other side deleted a wall before it. Pass `resolutions` {conflict id: central | local} to settle conflicts. Elements keep a persistent identity (ifc_guid, equal to their IFC GlobalId, or your own external_id). Pass `empreinte_base` (SHA-256 of the base you loaded) to refuse a merge on another base; the answer gives the SHA-256 of the three versions and of the result.
