One worksheet, one header-row table, a bounded numeric/boolean function set (IF/AND/OR/NOT/ROUND/ABS/SUM/AVERAGE/MIN/MAX/COUNT) — anything else (VLOOKUP, cross-sheet refs, non-uniform per-row formulas, …) is named and reported in rejectedColumns rather than guessed; the rest of the sheet still compiles. The returned spec is NOT …
Search document — Deterministic, LLM-free search over an uploaded PDF/DOCX: ranks the document's pages/sections against your query (term-overlap, no embedding model, no network call) and returns the top matches with page/section citations and verbatim quotes. Cost is bounded by topK, never by document length — use this instead of reading a whole large document into your own context.
