probes: 75

The exact question asked of a corpus, kept verbatim (code column): a Python regex on one document, a SPARQL query on a public endpoint, a shell request. result_count/result_of is the re-run figure on result_date; matches_excerpt says whether that figure is the one quoted in the observation (0 = differs, both kept).
