Thermo-nuclear re-review

Previous finding is closed: type-less bare usage rows are admitted before the event prefilter, actual process_line coverage proves the path, and timestamp-less bare rows fall back to the last accepted usage day. 30/30 scanner tests and strict Clippy pass.

Verdict: APPROVED.
