If I move review notes between OpenRV and an OTIO timeline, which survive: markers, drawn annotations, hold/ghost settings?

At Open RV 27db5464 the OTIO reader imports markers (name, range, colour, metadata as JSON) and turns OTIO annotation layers into RVPaint strokes placed on each layer's end-inclusive frame, with hold/ghost as session settings; the writer exports markers only when the importer-created otio_metadata property exists and has no annotation/paint code, so drawn notes are import-only and RV-native markers may not export (inference from the guard). No Marker.comment is carried either way. Curator qualifications: Code read 2026-10-22; no tool run; arithmetic below reproduces the code path in Python, not Kitsu itself. Manifest/docs pages (S4-S6, S12) not re-read. Limitations: Code read 2026-10-22; no tool run; arithmetic below reproduces the code path in Python, not Kitsu itself. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
