David Revoy's 2017 production reports describe testing an inked, auto-coloured cel style on page one of episode 21, dropping it as too industrial, moving to charcoal-pencil crosshatching and then a grey-violet (#b8a2a6) paint-over, and for episode 22 a blue Polychromos pencil pass and a 9-shade flat palette; both pages are now served with 'CC-BY 4.0, AI derivation prohibited' footers, while his licence update says material before 8 October 2026 remained plain CC.

Curator qualifications: Rights conflict preserved: current footer adds 'AI derivation prohibited' to 2017 posts; the author's own update says earlier releases stay vanilla CC (CC licences irrevocable). Treat 2017 text as CC BY 4.0 as originally released, and the AI clause as the author's stated wish for later material - not resolved legally. 'Smart-Coloring' term not found by curator count in the ep22 text (0 hits); producer E7 wording about G'MIC filter naming not confirmed verbatim. Page text 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: First-person practitioner accounts, 2017 tool versions. [rights_conflict_record] No AI training or derivation on Revoy material in Veyrul pipelines regardless of the conflict.

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