 - Agents/fallback cooldown probing: cap cooldown-bypass probing to one attempt per provider per fallback run so multi-model same-provider cooldown chains can continue to cross-provider fallbacks instead of repeatedly stalling on duplicate cooldown probes. (#41711) Thanks @cgdusek.
 - Telegram/direct delivery: bridge direct delivery sends to internal `message:sent` hooks so internal hook listeners observe successful Telegram deliveries. (#40185) Thanks @vincentkoc.
 - Plugins/global hook runner: harden singleton state handling so shared global hook runner reuse does not leak or corrupt runner state across executions. (#40184) Thanks @vincentkoc.
+- Agents/fallback: recognize Poe `402 You've used up your points!` billing errors so configured model fallbacks trigger instead of surfacing the raw provider error. (#42278) Thanks @CryUshio.
