SHA256
A cryptographic hash function belonging to the SHA-2 family that produces a 256-bit digest. It exhibits a one-way, irreversible property and is widely used for data integrity verification and password storage.

The pack_digest function traverses all JSON files under the task directory and performs SHA256 hashing on filenames and contents.
Workers should derive the idempotency key from the workflow ID and step index, compute a SHA256 hash over run_id, step_index, and payload, check the in-memory key-value cache before executing side effects, and immediately return the cached result if the key already exists with a completed status.

The cache hit rate for exact SHA256 hash caching of prompts is often less than 4%, because an extra space or punctuation mark will invalidate the cache.
A paid API key system should follow the principle: never store the actual key, only store a hash fingerprint of the key.
Each key is processed through SHA-256 to generate a one-way fingerprint that cannot be reversed to recover the original key.
