+- **fix(tests):** drain three base-reds on the release branch — the Vietnamese locale regained parity with English (6 keys added), the chatCore SSE test now asserts the comment-free default that #10539 introduced instead of the trailer it replaced, and the Antigravity cloudcode test asserts the missing-messages guard it is named for instead of a `/ok/` regex that only ever matched the "ok" inside `: x-omniroute-tokens-in` ([#10704](https://github.com/diegosouzapw/OmniRoute/pull/10704))
