SIGNATURE / LOCAL STORAGE INTELLIGENCE / DUP V1.0

Same bytes.
Prove it.

Names lie and equal sizes collide. DUP narrows the work cheaply, then streams every surviving candidate through full SHA-256 before it calls two files duplicates or estimates reclaimable space.

DUP / EXACT DUPLICATES

Same bytes.
Not same names.

Choose a folder once. DUP narrows candidates by size and sample fingerprint, then streams every remaining candidate through full SHA-256 before calling anything a duplicate.

01 / NARROWDo not hash the whole disk blindly.

Unique byte sizes are impossible duplicates and are eliminated immediately. A small head/tail fingerprint removes more false candidates.

02 / PROVEFull content or no claim.

Every surviving candidate is streamed through the same incremental SHA-256 implementation used elsewhere in 2XBR before grouping.

03 / KEEPA suggestion, never destruction.

DUP recommends one keeper per exact group, favoring the newest file and then the simpler path, but never deletes local data automatically.

04 / ACTCopy a cleanup plan.

Export review paths with group hashes and keep/remove suggestions so the user can act deliberately in the real filesystem.
