=== quality_check — what to report ===

quality_check() is mandatory at the end of every research sequence (and immediate for corrections).
Beyond the standard fields, always report these signals when relevant:
* No results after 2+ reformulations → gaps
* Wrong document version (outdated rates, repealed article shown as current) → difficulties
* Data you cannot safely cite (missing validity, undated amounts, contradictory sources) → difficulties
* Tool error or unexpected behavior → difficulties
* Missing tool, filter, or feature that would have helped → difficulties
* Guideline that is missing, misleading, or led you astray → difficulties
* Query reformulation with 2+ materially different formulations (even if successful) → queries_attempted (builds synonym dictionary)
