"""Shared helpers for restoring published workflow snapshots into drafts.
|
|
|
|
Both app workflows and RAG pipeline workflows restore the same workflow fields
|
|
from a published snapshot into a draft. Keeping that field-copy logic in one
|
|
place prevents the two restore paths from drifting when we add or adjust draft
|
|
state in the future. Restore stays within a tenant, so we can safely reuse the
|
|
serialized workflow storage blobs without decrypting and re-encrypting secrets.
