In Open RV 27db5464 the test annotation tool, the OTIO annotation import hook and the Mu Annotate mode all write paint components named type:id:frame:annotation and register them in frame:N.order, so any of them can produce drawings the viewer renders the same way. Curator qualifications: Code read 2026-10-22 at OpenRV 27db5464; nothing run. Curator amendment CA-AM-0040 (2026-10-22): Correction (curator, code_derived_inference): only the two Python writers (annot_tools.py, otio_reader annotation_hook.py) name components type:id:frame:annotation. The Mu Annotate mode (annotate_mode.mu L446, readback d5223ff5) names them '%s.%s:%d:%d:%s_%d' = type:id:frame:<encoded user>_<process id>, and the reference manual (chapter sixteen, readback e9fcd704) documents type:id:frame:user. All three register names in frame:N.order, so rendering is unaffected, but tools that parse the last name field get 'annotation' for imported or scripted strokes and a user/process tag for hand-drawn ones. Limitations: Code read 2026-10-22 at OpenRV 27db5464; nothing run. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
