Looks good. This is a straightforward dependency pinning change in mix.exs with no behavioral code changes, and the selected versions align with the lockfile versions noted in the PR description.

Quick sanity notes:

• Pinning removes version drift and improves reproducibility/supply-chain control.
• Runtime-impacting deps (req, optional nx, optional abacus) are pinned to concrete versions already in use.
• Dev/test-only deps (ex_doc, mimic) are similarly pinned and low risk.

No concrete correctness, security, migration, or API breakage issue is evident from this diff.
