The branch stored scopejson, desiredstate and params as sa.JSON, the only JSON
columns in the product. MySQL 5.6 has no JSON type - it arrived in 5.7 - and the
migration failed there with a bare syntax error near the word JSON.
They are TEXT now, through a JSONText type decorator, so the seventeen call sites
still assign and read dicts. The convention elsewhere is already TEXT:
guides.blocksjson, geenforce.manifestjson.
Spec regenerated: 331 paths, 477 operations across 22 surfaces.
