Corrections Log
When HORIZON publishes incorrect data we log the correction here. The record is updated, the prior version's hash is preserved, and a new audit entry is created. We never silently overwrite history.
2026-05-13 — Per-country death attribution capped
Issue: The v1.5 extractor attributed cluster-total death counts to individual countries via article-origin metadata. Specifically, US news articles reporting the MV Hondius cluster total of 3 deaths were incorrectly attributed as 3 US-national deaths.
Fix: Extractor upgraded to v1.6 with the article-metadata fallback removed. Added a global authoritative cap that rejects per-country proposals where the proposed count exceeds the WHO Disease Outbreak News total. DB reset for affected countries (US: 11/0/3 → 1/0/0, ES: 1/0/0 → 0/0/0).

2026-05-13 — Live AIS source corrected
Issue: MV Hondius position on the live map was stale because the only working AIS source (myshiptracking.com public page) was serving cached data more than 7 hours old. AISStream had no satellite coverage for the vessel's mid-ocean position; Kpler subscription unresolved.
Fix: CruiseMapper connector added as a fresh live AIS source; verified to return current vessel position within minutes of the AIS receiver. Dead-reckoning algorithm upgraded to COG/SOG projection (pure for first 6h, blended for 6–12h, route-interpolation fallback).
