 ### Fixes
 
 - Telegram/DM draft finalization reliability: require verified final-text draft emission before treating preview finalization as delivered, and fall back to normal payload send when final draft delivery is not confirmed (preventing missing final responses and preserving media/button delivery). (#32118) Thanks @OpenCils.
-- Discord/audit wildcard warnings: ignore "\*" wildcard keys when counting unresolved guild channels so doctor/status no longer warns on allow-all configs. (#33125) Thanks @thewilloftheshadow.
+- Discord/audit wildcard warnings: ignore "*" wildcard keys when counting unresolved guild channels so doctor/status no longer warns on allow-all configs. (#33125) Thanks @thewilloftheshadow.
+- Discord/channel resolution: default bare numeric recipients to channels, harden allowlist numeric ID handling with safe fallbacks, and avoid inbound WS heartbeat stalls. (#33142) Thanks @thewilloftheshadow.
 - Exec heartbeat routing: scope exec-triggered heartbeat wakes to agent session keys so unrelated agents are no longer awakened by exec events, while preserving legacy unscoped behavior for non-canonical session keys. (#32724) thanks @altaywtf
 - macOS/Tailscale remote gateway discovery: add a Tailscale Serve fallback peer probe path (`wss://<peer>.ts.net`) when Bonjour and wide-area DNS-SD discovery return no gateways, and refresh both discovery paths from macOS onboarding. (#32860) Thanks @ngutman.
 - Telegram/multi-account default routing clarity: warn only for ambiguous (2+) account setups without an explicit default, add `openclaw doctor` warnings for missing/invalid multi-account defaults across channels, and document explicit-default guidance for channel routing and Telegram config. (#32544) thanks @Sid-Qin.
