Evidence Fusion Ledger: Bayesian Log-Odds Waterfall

Debunking a viral claim rarely comes down to one smoking gun — real OSINT teams cross-check geolocation and EXIF metadata against the claimed scene, look up how old and reputable the publishing domain is, diff the page against its earliest Archive.org snapshot, count independent corroborating sources, and check whether cited "experts" hold real credentials. This 2D ledger renders each of those checks as a bar in a running log-odds waterfall and a marker on a live sigmoid curve, fusing whichever sources you keep active into a single Bayesian trust score, and lets you dial in a reliability threshold and a data-quality noise level to see how an investigation's confidence degrades when evidence is thin, weak, or unreliable.
