Bug type

Behavior bug (incorrect output/state without crash)

Summary

Description

After streaming completes, a duplicate final message is sent instead of the draft preview being edited in-place. One of the duplicates is then deleted after a short delay.

Environment

• OS: Windows 11 + WSL2 Ubuntu 24.04
• Channel: Telegram DM
• Networking: WSL2 mirrored mode

Configuration

"streaming": "partial"

Related

Possibly related to fixes in 2026.3.7 changelog:

• Telegram/DM draft streaming restoration (fix(telegram): restore DM draft streaming #39398)
• Telegram/DM draft finalization reliability
• Telegram/DM draft duplicate display

Issue persists after updating to 2026.3.7.

Log Evidence

Duplicate messages consistently appear within ~1 second of each other, correlating with stale-socket health-monitor restarts:

10:10:24 telegram sendMessage ok message=2892
10:10:25 telegram sendMessage ok message=2893

10:31:50 telegram sendMessage ok message=2929
10:31:51 telegram sendMessage ok message=2930

11:52:55 telegram sendMessage ok message=2979
11:52:56 telegram sendMessage ok message=2980

Steps to reproduce

1. Configure Telegram channel with streaming: "partial"
2. Send any message to the agent
3. Observe streaming output in Telegram DM

Expected behavior

The streaming draft preview should be edited in-place into the final message. No duplicate message should appear at any point.

Actual behavior

1. Streaming draft preview appears (message updates in-place while generating)
2. Streaming completes
3. A second complete message is sent containing the full streamed content
4. After a short delay, one of the two duplicate messages is deleted
