The export chat feature repeated the initial user prompt 3 times because it was included from input_data.messages in the MESSAGES_SNAPSHOT, echoed again in run_messages, and then unconditionally prepended by the export utility. Replace the blind unshift with deduplication logic that ensures the initial prompt appears exactly once. Closes #1320 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
✅ Deploy Preview for cheerful-kitten-f556a0 canceled.
