 - Agents/error rendering: ignore stale assistant `errorMessage` fields on successful turns so background/tool-side failures no longer prepend synthetic billing errors over valid replies. (#40616) Thanks @ingyukoh.
 - Agents/fallback: recognize Venice `402 Insufficient USD or Diem balance` billing errors so configured model fallbacks trigger instead of surfacing the raw provider error. (#43205) Thanks @Squabble9.
 - Dependencies: refresh workspace dependencies except the pinned Carbon package, and harden ACP session-config writes against non-string SDK values so newer ACP clients fail fast instead of tripping type/runtime mismatches.
+- Gateway/config errors: surface up to three validation issues in top-level `config.set`, `config.patch`, and `config.apply` error messages while preserving structured issue details. (#42664) Thanks @huntharo.
