1. Strip trailing garbled IPA after proper [IPA] brackets (e.g. "sea [sˈiː] si:" → "sea [sˈiː]") 2. Add prefix matching for merged tokens where OCR joined headword with garbled IPA (e.g. "schoolbagsku:lbæg" → "schoolbag [skˈuːlbæɡ]") 3. Broaden guard to also trigger on trailing non-dictionary words (e.g. "scare skea" → "scare [skˈɛə]") Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
