Bug Description

Agent completes tasks successfully but doesn't send the final completion message until I interrupt to ask for status. The work is already done (files created, tools executed), but the turn never finishes on its own.

Steps to Reproduce

  1. Send long-running task request via Telegram (e.g., "convert report to audio")
  2. Agent starts work, sends status updates every 3 minutes
  3. Wait for completion (verify files created, check timestamps)
  4. Observe: no final "done" message sent
  5. Send interrupt: /status or "what's the status?"
  6. Observe: agent immediately responds "Done" with already-completed work

Expected Behavior

Agent should automatically send completion message when task finishes, without requiring user interrupt.

Actual Behavior

Example from May 7, 2026:

8:13 PM - User: "convert report to audio" 8:14 PM - Agent: "On it" [executes read_file ×7, text_to_speech ×13, ffmpeg] 8:16-8:28 PM - Agent sends status heartbeats every 3 min 8:28 PM - Last heartbeat: "15 min elapsed — receiving stream response" [silence - work is complete but no message sent] 8:29 PM - User: "What is status of audio file" 8:29 PM - Agent: "Done — full audio version is ready" [file already existed]

Root Cause Analysis (optional)

The bug is in gateway/run.py line 949. len(history) counts session_meta entries but agent_messages was built from filtered history, causing message retrieval to fail silently when the count mismatches. The completion message gets queued but never sent until user interrupt forces a flush.
