trust_baseline: 0.5 — at the default 0.8 only S-11 cleared (1 of 17); the corpus is weak relative to 0.8, so per the corpus-fit rule the baseline was lowered to 0.5, at which 12 sources clear and the ranking discriminates. All combined_score values recomputed at 0.5.
scoring_rubric: trust_score ∈ [0,1] = P(finding replicates cleanly); usefulness ≈1–5 log scale = how much the data moves the question if true; combined_score = usefulness × (trust_score − 0.5), ≤ 0 ⇒ not curated.
rank_departures: none. The top 5 by combined_score already cover both sides (research-related: S-15; zoonosis: S-12, S-2, S-4; neutral/foundational: S-11) and rest on 5 distinct data-bases (S-12, S-15, S-11, D-2, S-4) — no dataset monoculture. Script reported no strong skew at baseline 0.5, so no swap or unrepresented-position include was needed.
D-node reconciliation: D-4 (scorer A) merged into D-1 (scorer B) — same SARS-CoV-2 reference-genome / early-GISAID dataset. S-9 data_basis repointed D-4 → D-1; D-4 tombstoned (merged_into: [[D-1 …]]) and moved to data-bases/merged/. D-2 (Huanan swabs) and D-3 (Worobey case-geolocation) confirmed distinct, left live.
