We engineered this zero-bloat Python 3.12+ / AsyncIO blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

AI Dev Tool: Serverless S3/R2 Presigned Multipart Upload Signer on Cloudflare Edge
This module implements a serverless presigned multipart upload signer for S3/R2 on Cloudflare Edge.
It utilizes an exponential backoff strategy with jitter for handling retries and provides structured JSON logging.
The module is designed to operate within bounded concurrency limits to prevent overload.
Usage:
python -m ai_dev_tool_presigner --bucket <bucket_name> --key <object_key> --part-size <part_size> --num-parts <num_parts>
Configuration:
The module uses a typed configuration with strict validation to ensure correct settings.
The configuration includes the following parameters:
- bucket: The name of the S3/R2 bucket.
- key: The key of the object to be uploaded.
- part-size: The size of each part in the multipart upload.
- num-parts: The number of parts in the multipart upload.
Error Handling:
The module uses deterministic error handling to ensure consistent behavior in case of errors.
It logs errors in a structured JSON format for easy analysis and debugging.
