[json]

The [json] section carries advanced restart metadata used by internal JSON interfaces. Most users should configure the calculation through the normal route and [guess] section instead.

scf_type, basis, library, do_init

Keyword	Type	Default	Meaning
scf_type	string	empty	Saved/imported SCF reference metadata used by a JSON guess.
basis	string	empty	Saved/imported basis metadata used by a JSON guess.
library	string	empty	Saved/imported basis-library mapping used by a JSON guess.
do_init	string	no	Internal no/yes marker set when a JSON basis/library mismatch requires updating scf.init_*; not a normal user switch.

These keys are compatibility metadata, not an alternative to the .oqp method, basis, and reference syntax.
