Corrections

  • 2026-08-24 app: apps A destination may only be published once it has been resolved, not assumed. (Edition-specific official destinations assumed Each edition points at the same verified official entry point until Task 7 verifies edition-specific destinations; no score change)
  • 2026-08-23 price: prices/kr Price facts must carry the date they were observed so staleness is visible. (Korean tier prices recorded without a stated observation date Every Korean price observation carries an explicit 2026-08-12 observation date; no score change)
  • 2026-08-22 methodology: 0.1 The published weight table needed an unambiguous definition before any score was calculated. (Overall product/local-language component described as a single dimension Overall product/local-language component is the mean of product reliability and local-language performance; score changed)
