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. |

๐ก Non-Latin-1 API keys always fail
For keys containing characters outside Latin-1, provided_key.encode("utf-8") changes the header bytes. Every valid request receives 401.

๐ Runtime secret source remains noncompliant
The test reinforces runtime use of CODEC_CARVER_API_KEYS. AGENTS.md requires this authentication path to migrate to a credential registry.

๐ Test bypasses HTTP decoding
The direct require_api_key call only proves malformed input returns 401. It never tests a valid non-ASCII key through the HTTP client.
