Ask the Index

Ask a question this corpus can actually answer.

Questions are answered from public Index pages and the source records behind them. Every sentence in an answer carries the record it came from, and the assistant states when the corpus cannot support an answer rather than filling the gap.

What an answer looks like

Ask a question above. Each answer is assembled in the same four parts, so you always know where a number came from and where it stops.

  1. AnswerProse that states what the literature and the regulatory instruments support, written to the same register as the pages it draws from.
  2. Values usedThe specific limits and concentrations behind the answer, each tied to its instrument, its basis, and the record it was read from.
  3. What it does not coverThe edges of the answer, named plainly — adjacent metals, jurisdictions, or brand-level data the corpus does not hold.
  4. SourcesThe Index pages and source records cited, each a link you can open and check for yourself.
