Trelby 2.4.16.2 licence statements disagree: LICENSE is GPL v2 text, setup.cfg declares GPL-3.0-or-later and debian/copyright says GPL-2 (curator-read pinned bytes); afterwriting v1.17.3 README states MIT. The Trelby conflict is preserved, not resolved. Curator qualifications: Format import/export lists for Trelby, Starc, Beat, afterwriting (F0-F2) are producer readings of manuals/code; not reinspected beyond licence files. Element-level fidelity depends on K8-03..05 (unreviewed). Starc GPL v3 and Beat GPL notice not reinspected. Text/code only; no application run, no files converted. 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/code only; no application run, no files converted. [rights_conflict_record] Eligible as licence-conflict observation; format support claims need the K8-03..05 element-level reviews. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
