 ### Fixes
 
 - Security/auth labels: remove token and API-key snippets from user-facing auth status labels so `/status` and `/models` do not expose credential fragments. (#33262) thanks @cu1ch3n.
+- Security/audit denyCommands guidance: suggest likely exact node command IDs for unknown `gateway.nodes.denyCommands` entries so ineffective denylist entries are easier to correct. (#29713) thanks @liquidhorizon88-bot.
 - Docs/security hardening guidance: document Docker `DOCKER-USER` + UFW policy and add cross-linking from Docker install docs for VPS/public-host setups. (#27613) thanks @dorukardahan.
 - Docs/security threat-model links: replace relative `.md` links with Mintlify-compatible root-relative routes in security docs to prevent broken internal navigation. (#27698) thanks @clawdoo.
 - iOS/Voice timing safety: guard system speech start/finish callbacks to the active utterance to avoid misattributed start events during rapid stop/restart cycles. (#33304) thanks @mbelinky; original implementation direction by @ngutman.
