 ### Fixes
 
+- Discord/Gateway: handle close code 4014 (missing privileged gateway intents) without crashing the gateway. Thanks @thewilloftheshadow.
 - Security/Net: strip sensitive headers (`Authorization`, `Proxy-Authorization`, `Cookie`, `Cookie2`) on cross-origin redirects in `fetchWithSsrFGuard` to prevent credential forwarding across origin boundaries. (#20313) Thanks @afurm.
 - Auto-reply/Runner: emit `onAgentRunStart` only after agent lifecycle or tool activity begins (and only once per run), so fallback preflight errors no longer mark runs as started. (#21165) Thanks @shakkernerd.
 - Auto-reply/Prompt caching: restore prefix-cache stability by keeping inbound system metadata session-stable and moving per-message IDs (`message_id`, `message_id_full`, `reply_to_id`, `sender_id`) into untrusted conversation context. (#20597) Thanks @anisoptera.
