The FDX conformance suite is the test corpus we use to verify that a screenplay survives the round trip from Final Draft to Arqo and back to Final Draft. Every fixture below exercises a feature that real-world production drafts depend on — locked scene labels with letter suffixes, the WGA revision-mark cycle, scene properties with ARGB colours, multi-paragraph script notes, the lot.
For each fixture the suite parses the bytes, projects them into a shared canonical screenplay model, emits FDX back out, re-parses the emitted bytes, and structurally deep-equals the two canonical forms. Any difference is a fail. There is no half-credit; no “close enough.”
