Partially verified: the curator re-read S15; S13, S16 were not re-read by the curator and rest on the producer's pinned reading. A systematic review of 27 human-robot interaction studies (arXiv v4, 2019; arXiv non-exclusive licence) frames robot motion with the twelve principles and its count table shows no reviewed study for Timing, Staging, Solid Drawing or Appeal, while Secondary Action and Straight Ahead/Pose to Pose were most used.

Curator qualifications: Partially verified: the curator re-read S15; S13, S16 were not re-read by the curator and rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S13: HTTP 200, bytes equal to the producer pin; S16: HTTP 200, bytes differ from the producer pin. Papers read 2026-10-22; no animation made or tested. Table read from flattened PDF text (names and counts in matching order). LA Film School blog (S16) not re-read; its squash-and-stretch opinion stays producer-reported and uncited. Thesen 2020 critique blocked (unread).

Limitations: Papers read 2026-10-22; no animation made or tested.

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