"""Unit tests for ``src.json_utils.parse_json``.
|
|
|
|
IMP-28 L4 — `_parse_json` dedup unit u2.
|
|
|
|
Pins the shared helper semantics that previously lived in
|
|
content_editor.py / design_director.py / kei_client.py (fuller form) and
|
|
pipeline.py (simple form). The fuller form is a strict superset of the
|
|
simple form; these tests cover both axes.
