Overview

The formulas section of an import document — which is not the shape SerializeFormula emits (docs/core-gem-contract.md §4.2). Four differences, each of which would silently produce a file that does not round-trip:

  • one flat entry per version, repeating key/scope/owner, rather than a formula with a nested versions array;
  • owner as a {type, id} object, omitted entirely when nil;
  • no id, formula_id, version_number, created_at or updated_at — none of them are import keys;
  • required written out as a real boolean, because the import default is "anything not literally false" and omitting it is therefore not the same as round-tripping it.

Version order is load-bearing, not cosmetic. SupersedeFormulaVersions applies entries in file order, so a version that takes over the tail of a range has to land after the one giving it up; an out-of-order export re-imports straight into PartialSupersedeError.
