The most direct open source found is Mohr's 2019 QUT PhD thesis (CC BY-NC-ND 4.0 per the repository record). It reports, from Menache (2011, a book not read here), a three-way split: squash and stretch and anticipation, follow-through and exaggeration beyond physical limits 'cannot be accomplished with mocap'; overlapping action, straight-ahead action, ease in/out, arcs and secondary motion occur naturally; timing, appeal and personality work either way. Mohr tests this by practice (four cycles with several performers, the last with a mime artist) and finds cartoon-style movement is achievable at the capture stage under stated conditions, while squash and stretch stayed bound to the performer's body and pose-to-pose capture was used to get past physical limits. Evidence is qualitative practice research, not a controlled comparison; a 50-student experiment (Mou 2018) is consistent on extreme poses but does not test the twelve principles.

Curator qualifications: All 7 excerpts located in the Mohr thesis copy; the three-way split is reported from Menache (2011, unread), so it is second-hand. Thesis licence CC BY-NC-ND 4.0 per repository record (producer). 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: [component_reuse_restriction] Menache claim second-hand; repository licence not re-read by curator.

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