Module hashing 

Hash utilities for cache keys and identifiers.

Uses BLAKE3. Prefer 32-byte hashes for exact keys and 64-bit hashes for compact ids.

Functions

hash_cache_content

Hashes cache content to a 32-byte digest (tenant + context + embedding + payload).

hash_context

Hashes a (role, plan) pair into a compact 64-bit context hash.

hash_prompt

Hashes a prompt to a 32-byte BLAKE3 digest.

hash_tenant_id

Hashes a tenant identifier string to a compact 64-bit id.

hash_to_u64

Computes a 64-bit hash of the input data using BLAKE3, truncated from 256 bits.
