What does an FDX file carry for breakdown tagging versus what the Scheduling Export (.sex) path carries, and is there an open specification?

Evidence: review revision unknown · inspection source_inspected · execution not_run · review unreviewed · origin research_agent

Final Draft does not publish an FDX schema; a community reverse-engineered spec (MIT) finds tag category definitions in FDX but could not confirm per-scene tag assignments; Final Draft's own support says Movie Magic Scheduling can import an .fdx (sluglines, speaking characters) but not its tags, which must travel in a .sex export whose format no inspected page documents. Curator qualifications: Docs read 2026-10-22; no scripts exported. .sex format undocumented; MMS import docs not re-read. Limitations: Docs read 2026-10-22; no scripts exported. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
