What

When the Workflow tool receives its args as a JSON-encoded string starting with { or [, it now parses it back into a real object or array rather than failing. The repair is controlled by the tengu_jade_compass flag, which falls back to on, so absent a server value the repair applies. With the flag off the same case is only recorded, and the original malformed input is passed through unchanged.

Details
  • The detected shape is classified as args_json_string_to_object or args_json_string_to_array, each with a _named variant.
  • When the flag is off, a _detect_only suffix is added to that classification.
Evidence

args_json_string_to_object

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
