Context

DeepSeek suggested replacing SHA-1 with blake2b. That has compatibility implications because fingerprints are user-visible.

Task

Research whether migrating stable digests is worth it and what compatibility path would be required.

Acceptance criteria

  • Short note comparing keep-SHA1-with-comment vs migrate-to-blake2b.
  • Explicitly discuss baseline/fingerprint compatibility.
  • No code behavior changes.

Verification

  • Cite affected files/functions and current fingerprint consumers.
