…ed through to inference (#17693) ## Background The published Amazon Bedrock provider rejected S3-hosted images before inference, forcing users to load image bytes into memory. ## Root Cause The model declared no native URL support, causing the core downloader to reject s3:// URLs, while Bedrock message conversion also unconditionally rejected URL-backed files. Reproduction confirmed AI_DownloadError through generateText and AI_UnsupportedFunctionalityError through direct provider use. ## Summary The provider now recognizes s3:// image URLs and serializes user and tool-result images as Bedrock s3Location sources. Bedrock image source types and a patch changeset were updated. ## Testing Added regression coverage for native S3 URL declaration and conversion of user and tool-result S3 images. ## End-to-end Validation - `AWS_REGION=us-east-1 pnpm -C examples/ai-functions exec tsx src/reproduction/amazon-bedrock-s3-image-url.ts` using a temporary Nova variant reached live Bedrock and returned `Provided S3Location not found`, confirming pass-through instead of the previous pre-inference `AI_DownloadError`. ## Related Issues Fixes #15792 Closes #17676 Backport of #17681 Co-authored-by: tommyOtsai <171396937+tommyOtsai@users.noreply.github.com>
