Contributor guide
Research direction
No file, test, or entry point is named. Begin by reproducing the reported benchmark with 1 million JSON-string attributes and LIKE '%%', then locate the existing LIKE query path and establish a measured performance baseline; done means faster queries with unchanged results.
