-## Firm requirements for every entry
-
-Never consider a prompt without a proven yield. An entry **must** satisfy all
-three:
-
-1. **The prompt is available.** Published verbatim by a credible source
-   (lab PDF, official dataset, research page). Collect it as `.md` in the
-   entry folder. If the source is a PDF, machine-extract the text and note the
-   provenance in an HTML comment at the top of the file; always link the
-   authoritative source.
-2. **It is related to a research task.** Mathematics, natural sciences,
-   engineering, or biomedical discovery — not demos, toys, or benchmarks
-   without research significance.
-3. **It is battle-tested and produced significant field yield.** The result
-   must be independently verifiable: a peer-reviewed publication, wet-lab
-   validation, formal verification (e.g. Lean), or expert-reviewed proof.
-   State the yield concretely in the entry README (numbers beat adjectives).
-
-## Entry layout
-
-```
-prompts/<lab>/<entry-name>/
-  README.md          # metadata table + analysis of what made the prompt work
-  prompt.md          # the verbatim prompt(s), with provenance comment
-  transcript.md      # optional: full released transcript(s)
-```
-
-The entry `README.md` must include a metadata table with: lab, model, field,
-result (yield), date, and source links — mirroring the existing entries.
-
-## Index
-
-Update the root `README.md` gallery table when adding an entry (lab section,
-entry link, field, yield, date).
-
-## Extraction notes
-
-When converting source PDFs to `.md`:
-
-- Preserve wording exactly; only reflow line wrapping.
-- Document the source URL and any extraction caveats in a leading HTML comment.
-- Prefer official text releases (e.g. HuggingFace prompt dumps) over PDF
-  extraction when both exist.
-- Inline mathematics extracted from typeset PDFs is often imperfect — say so
-  and defer to the authoritative source.

 - Extraction provenance is documented in an HTML comment at the top of every
