The 2026-08 audit consolidated identical bodies under different names and files (five auth views' CSS, two Workspace formatDate()s, four modal blocks) while the derive readout led with name groups (to_dict ×25, main ×5, load ×6) that were convention or coincidence. - proposal_summary ranks dup:<sha> groups above name groups, wider file spread first, and carries `files`; scoped rows (#2869) are in the readout, since that is where view-level copies live. - extract_definitions fingerprints a CSS rule by its declarations — the row identity already carries the selector — so .closed-msg / .error-block / .success-msg with one body are one dup group. One-time effect: judged css rows whose stored fingerprint predates this may show a recheck on the next refresh (the judgment stands; re-confirm).
