At ink 35c63e52 (v1.2.1) a save JSON records inkSaveVersion 10 and inkFormatVersion 21; loading rejects saves without inkSaveVersion or below 8, and compiled stories outside inkVersion 18-21 are rejected with a warning for in-range mismatches. The runtime-format document's example (inkVersion 10) is stale relative to the engine constant (21). Curator qualifications: Curator addition (code inference): the save loader has no upper-bound check, so a save written by a newer engine (inkSaveVersion > 10) is not rejected by the version gate; behaviour after that is unverified. RunningYourInk.md ToJson/LoadJson section (E4) not re-read. Static reading at 35c63e52; no ink story compiled or loaded. Limitations: Static reading at 35c63e52; no ink story compiled or loaded. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
