Code Review
This pull request updates the TRANSCRIPT_MODELS configuration and enhances error handling in createTranscript by capturing the last error encountered during model iteration. The reviewer suggested safely converting errors to strings to prevent potential TypeError exceptions and recommended conditionally formatting the final error message to avoid displaying 'undefined' in edge cases where no error is captured.

Google retired gemini-3.1-flash-lite-preview, causing all video/audio transcript requests to fail with 404 since 2026-07-09. The fallback loop only continued on 429/RESOURCE_EXHAUSTED, so the second model (gemini-2.5-flash) was never tried and the AI response was written as ERROR. - Replace the retired preview model with GA gemini-3.1-flash-lite - Also try the next model on 404/NOT_FOUND (model retired or inaccessible), not just quota errors - Include the last error in the all-models-failed message instead of assuming quota limits Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Google retired

createTranscriptonlycontinued to the next model on429+RESOURCE_EXHAUSTED; any other error was re-thrown. So the second model (gemini-2.5-flash) was never attempted, and the AI response was written asERROR. ~248 video/audio articles since then have no transcript. Image OCR (Vision API) was unaffected.Changes
