decode persisted container withoutLabel lazy payload: %w

Error message

decode persisted container withoutLabel lazy payload: %w

What it means

In the persisted-Container decoder, the withoutLabel lazy case unmarshals its stored JSON payload into persistedContainerWithoutLabelLazy. This error fires when the payload is malformed or written by an incompatible schema version, blocking restoration of that Container step.

Solutions

1. Validate the payload's parentResultID and name fields
2. Invalidate and re-derive the stale persisted object
3. Escalate if reproducible on freshly persisted data
