~60 call sites across 24 model files now ride _json_read with each site's exact default preserved; 34 classes newly adopt the mixin (registry contract test expanded to 36). Reverses the old 'bare sites stay raising' ruling: a corrupt row degrades to its default instead of 500ing every serializing endpoint (docstring updated). Ratchet: json.loads( appears only in json_column_mixin.py. Known pre-existing: test_host_inventory enumerate_filesystems failures on this machine (verified via clean-tree stash rerun).
