At ExifTool 2200871d the README says it is distributed on the same terms as Perl (Artistic License or GPL), while the LICENSE file is the GPL v3 text; the repository ships 194 verification test files under t/images (722,199 bytes) with no file-level licence statement found; the separate sample-image archive replaces main images and strips previews 'to avoid copyright problems' while preserving EXIF/APP segments, without stating a licence.

Curator qualifications: Licence conflict preserved (Perl dual terms vs GPL v3 file); which terms cover t/images is not stated. Per-format counts (JPG 41, XMP 10, etc.) not re-counted. Text/metadata only; no images downloaded. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: Text/metadata only; no images downloaded. [component_reuse_restriction] Do not redistribute ExifTool test images in fixtures until terms are confirmed.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
