The workflow version is a structural digest
Two implementations must agree on whether a snapshot still fits its workflow. Moving a node on the canvas is not a change to the workflow it snapshots.
The rule
Normative: this is the rule
- A workflow's version is the first 16 hexadecimal characters of a SHA-256 digest over the workflow's structural data only.
- Presentational data (labels, canvas positions) must not change it.
Rule identifiers are permanent and are never renumbered. Each implementation publishes its own standing against these rules; this specification does not.spec 1.0-draft · INT-7 · changed in spec 1.0
