No blocking issues found.

The parenthesization (... || 0).to_f is correct. It ensures that if try(:[], field) returns nil, the fallback 0 is used, and then .to_f is applied to the final result. Both 0.to_f (returns 0.0) and "127.5".to_f (returns 127.5) behave as expected.
If JSONB values are stored as strings in the database, this fix addresses the root cause at the point of use. A deeper fix could normalize values at write time, but that is outside the scope of this plan and not required.
The existing rescue StandardError block on line 70 remains intact, preserving the error logging safety net.
