Step contract in 0.2.0

The 0.2.0 bundle uses its pinned built-in and sidecar contracts as part of the complete release. It does not provide the later Describe capability handshake or contract-version enforcement documented for Next.

:::warning No public plugin compatibility guarantee

Building a step against a source contract does not make it compatible, entitled, trusted, or deployable with 0.2.0. There is no supported 0.2.0 live plugin marketplace.

:::

Safe compatibility rule

• Use only step artifacts pinned in the installed release bundle.
• Confirm the component is reconciled by the pinned Operator.
• Confirm the runtime executes its phase.
• Validate representative traffic after activation.
• Treat empty, failed, or mismatched capability behavior as unsupported.

nexoctl scaffold and validation commands can assist development, but they do not establish a supported runtime deployment contract.
