How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Hugging Face Git LFS batch API actions.upload header Authorization presigned S3
💡 Result:
Hugging Face follows the standard Git LFS Batch API protocol for handling file uploads [1][2]. When an LFS file is uploaded, the process involves an interaction between the LFS client (such as the huggingface_hub library) and the Hugging Face Hub's LFS batch endpoint [3]. 1. Batch Request: The client sends a POST request to the LFS batch endpoint (e.g., /info/lfs/objects/batch) with the OID and size of the file [3][2]. 2. Upload Instructions: If the server does not already have the object, it returns an upload action object [1][2]. This object contains a presigned URL in the href field and, if required, an Authorization header in the header dictionary [4][5]. 3. Upload Execution: The client then performs a PUT request to the provided href [4][5]. If the Batch API response included a header object with authorization details, the client includes these headers in the PUT request to authenticate the upload directly to the underlying storage (typically Amazon S3) [4][1][6]. 4. Verification: If the Batch API response includes a verify action, the client sends a POST request to the specified verify URL after the upload is complete to confirm the object was successfully received [4][5]. The Hugging Face Hub uses Amazon S3 as its primary storage backend for Git LFS [6]. The presigned URL mechanism offloads the actual file transfer to S3, bypassing the Hub's main application servers for the binary data [4][6]. The huggingface_hub library handles these steps automatically, including constructing the necessary headers and managing multi-part uploads if the batch response indicates their use [5][3].

Forward the LFS upload Authorization header.
When actions.upload.header.Authorization is present, the PUT must send it. The bare client prevents the Hub bearer token from leaking to storage URLs. Add a wiremock test that checks the action header is present and the Hub bearer is absent.

Render the configured Hugging Face repository.
HfTopModelPublisher::with_config accepts a custom repository, but the model card always prints and loads DEFAULT_REPO. A configured repository therefore publishes a card with broken load instructions. Pass self.repo through build_hub_files and hub_readme, then test a non-default repository.
