Summary:\n- show provider-prefixed fallback labels for nested OpenRouter model ids in Telegram model picker\n- add regression coverage and changelog credit\n\nVerification:\n- pnpm test extensions/telegram/src/model-buttons.test.ts\n- OPENCLAW_TESTBOX=0 pnpm check:changed
When a Telegram turn ends with no visible final response, the dispatcher synthesized a NO_REPLY payload that silent-reply rewrite could turn into visible DM chatter such as "All quiet on my side."
Gate that synthesized fallback on group chats. DMs with no queued final response now stay quiet, while group/forum fallback behavior remains available when policy asks for a visible rewrite.
Tests:
- pnpm test extensions/telegram/src/bot-message-dispatch.test.ts
- pnpm check:changed
Move sentBlockMediaUrls recording from before sends to after successful
delivery completion. If a block send throws, the URL is not recorded,
so final fallback delivery retains the media attachment instead of
incorrectly deduplicating it.
Add regression tests for both success-path dedup and failure-path
media preservation.
Addresses ClawSweeper P2: block-failure → final-media-loss.
Non-streaming Telegram delivers each MEDIA: attachment twice — once
from the media-only block reply and once from the final reply. Track
media URLs sent via block replies and filter duplicates from final
replies.
Closes#78372
Telegram's deliverReplies dispatches via Grammy SDK directly, bypassing
deliverOutboundPayloads where the channel-mirror writer runs. Outbound
assistant replies were never appended to the session transcript, leaving
Telegram .jsonl files empty (the sessions.json sessionFile path was
populated but the file was never created on disk).
Add an optional transcriptMirror callback param to deliverReplies and
populate it from bot-message-dispatch's deliveryBaseOptions. Reuses the
existing appendAssistantMessageToSessionTranscript helper that
deliverOutboundPayloads already calls. Also mirrors preview-finalized
replies so the transcript captures all final assistant output.
Plugin SDK boundary expansion: re-export
appendAssistantMessageToSessionTranscript from
plugin-sdk/agent-harness-runtime so extension code can call it without
reaching into core src/. API baseline regenerated.
Addresses openclaw#75991 for telegram + CLI runtime combinations.
Supersedes openclaw#77484 (incorporates reviewer feedback: preview-
finalized mirror + changelog entry).
