Sorted low-confidence-first by default so the tricky names get your attention before the easy ones.
"Accurate real name" should always match the real name on the site (e.g. Csaba Kercso-Magos), never a nickname --
put announced/preferred names (Chabba, LJ, Lucy, Steph) in the separate "Prefers" column instead.
Edit directly in the row; tick Reviewed as you go -- reviewed rows are protected from every future regeneration.
Export when done and drop the file back into nzihl-broadcast-assets/assets/pronunciations.json.
This page loads that file live on every visit, so you're always looking at the current data.
Pick "Mat" or "Michael" in "Reviewing as" below to enable editing -- browsing/searching still works either way.
