Compute a deterministic SHA256 hash from a config dictionary.
This is the single source of truth for identity hashing across the entire
system. The dict is serialized with sorted keys and compact separators to
ensure determinism.
- Parameters:
config_dict (Dict[str, Any]) – A JSON-serializable dictionary.
- Returns:
Hex-encoded SHA256 hash string.
- Return type:
str
- Raises:
TypeError – If config_dict contains values that are not JSON-serializable.
