๐ Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a ๐ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: โช Minimal ยท up to This change makes malformed non-ASCII API-key headers return the existing 401 response instead of causing a server error. The remaining environment-based key configuration concern predates this change and is not worsened by it, so no actionable merge-blocking risk remains. ๐ฅ Pre-merge checks | โ 4 | โ 1โ Failed checks (1 warning)

๐ API keys still bypass registry
get_configured_api_keys still reads secrets from the environment. Repository policy requires runtime secrets from a credential registry, with environment variables limited to bootstrap transport.

๐ Info: Encoding preserves key matches
Starlette decodes header bytes as Latin-1. Encoding both operands changes bytes equally, so configured non-ASCII keys still match while avoiding string comparison failures.
