dc:description "analysis.py downloads the Hamburger and Hamilton PDF and extracts the text layer with pdftotext. It counts beat or pulsat, heart, two-vessel phrases, somite, neural fold, optic vesicle and blood island, and splits the text on stage headings. A stage counts as the beating heart only when its own text has both heart and beat or pulsat. This text layer has heart and has none of the beat or vessel phrases, so those clauses are unscored and no earlier-organ comparison is made.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0 stages whose text says the heart beats (n = 6). Interpretation: Aristotle's hen's egg is the chick. 'A speck of blood that beats' is the first stage text that says the heart beats or pulsates. 'Two vein-ducts with blood lead from it' is a pair of vessels in that description. Somites, neural folds, optic vesicles and blood islands appearing in an earlier stage mean something else is described before the beating heart. The three-day timing in the passage is not scored, because stage series are numbered rather than locked to three days in the text that will be parsed.";

"The extracted text names the heart six times, including fusion of the heart primordia and an S-shaped heart, and it never matches beat or pulsat. It also never matches two vessels, two veins, two arteries or vitelline. The beating and vessel clauses are unscored.",
"The text layer misreads some stage numbers, for example the thirteen-somite description is headed Stage 22. A dropped word is possible. No second copy was fetched because heart and somite were readable. The PDF states no license in the extracted text. n is the number of stage blocks that mention the heart.";

The claim fails if any earlier stage matches somite, neural fold, optic vesicle, or blood island, or if the heart description says the heart does not beat, or if vessels leading from it are stated as absent. If the PDF has no usable text layer after one further open copy of the same paper is tried, the verdict is inconclusive with reason data-unavailable. A textbook or embryology-wiki table is not admissible. If the series describes a heart but never says it beats, the beating clause is unscored and the verdict is mixed if another clause was scored, otherwise inconclusive with reason not-operationalizable.";
