test(telegram): cover getFile file-too-big errors

CHANGELOG.md

@@ -42,7 +42,9 @@ Docs: https://docs.openclaw.ai
 - Telegram: disable block streaming when `channels.telegram.streamMode` is `off`, preventing newline/content-block replies from splitting into multiple messages. (#17679) Thanks @saivarunk.
 - Telegram: route non-abort slash commands on the normal chat/topic sequential lane while keeping true abort requests (`/stop`, `stop`) on the control lane, preventing command/reply race conditions from control-lane bypass. (#17899) Thanks @obviyus.
 - Telegram: ignore `<media:...>` placeholder lines when extracting `MEDIA:` tool-result paths, preventing false local-file reads and dropped replies. (#18510) Thanks @yinghaosang.
+- Telegram: skip retries when inbound media `getFile` fails with Telegram's 20MB limit and continue processing message text, avoiding dropped messages for oversized attachments. (#18531) Thanks @brandonwise.
 - Auto-reply/TTS: keep tool-result media delivery enabled in group chats and native command sessions (while still suppressing tool summary text) so `NO_REPLY` follow-ups do not drop successful TTS audio. (#17991) Thanks @zerone0x.
+- Agents/Tools: deliver tool-result media even when verbose tool output is off so media attachments are not dropped. (#16679)
 - Discord: optimize reaction notification handling to skip unnecessary message fetches in `off`/`all`/`allowlist` modes, streamline reaction routing, and improve reaction emoji formatting. (#18248) Thanks @thewilloftheshadow and @victorGPT.
 - CLI/Pairing: make `openclaw qr --remote` prefer `gateway.remote.url` over tailscale/public URL resolution and register the `openclaw clawbot qr` legacy alias path. (#18091)
 - CLI/QR: restore fail-fast validation for `openclaw qr --remote` when neither `gateway.remote.url` nor tailscale `serve`/`funnel` is configured, preventing unusable remote pairing QR flows. (#18166) Thanks @mbelinky.
