Detailed Description

Patches or rebuilds Fabric state from a previously encoded EXR + JSON schema pair.

Does what the classes allow and reports the rest. Emitters, Sensors, Agents (including Locus and Presence) are patched by id or constructed; their Expanses are restored. Optional fields (position, orientation, color, size) are applied only when the schema records them, except that an absent position clears the entity's position. Callable name mismatches between schema and live entity are warned but do not abort the patch.

Live objects are never invented. Sinks, typed influences and perceptions, attachments, a Locus's view targets and every wiring source that needs a window, a network source or a callable are reported as warnings, and a wiring that cannot be restored falls back to commit_driven. A Hull needs a buffer and is skipped; a Mantle comes back as its plain box. Files from schema versions k_schema_min_version up to k_schema_version are read, with fields added since taking their defaults.
