 ### Fixes
 
+- Sessions: skip trailing custom transcript entries when checking tail assistant replies so embedded CLI gap-fill does not duplicate canonical assistant output. (#83635) Thanks @yaoyi1222.
 - Telegram: keep verbose tool progress visible without mirroring non-final progress into active session transcripts, preventing embedded provider replies from aborting mid-run. (#83631) Thanks @kurplunkin.
 - CLI: enforce the documented Node.js 22.19 runtime floor in the source launcher.
 - Agents/replies: persist queued follow-up user messages and assistant error stubs only once across model-fallback retries, preventing repeated provider rejections from corrupted same-role session transcripts. Fixes #83404. (#83417) Thanks @yetval.
