slv.inversion.cache.DEFAULT_COMPONENT_REVISIONS

slv.inversion.cache.DEFAULT_COMPONENT_REVISIONS: dict[str, int] = {'forward_operator': 2}

bumped when slv changes what it builds for the same config, so a file cached before the change is not read as the new kind. slv’s own revision is not in the key (see _version_tag()). forward_operator 2: receptors with an empty footprint have a row of zeros, so a missing row means no footprint.
