- Wheel inspection when package data, dependencies, or extras change.
- Deterministic CI coverage; keep credentialed live-target tests opt-in.

For an adapter that packages or launches a third-party harness, also verify the
repository integration rather than relying on the development workspace:

- Install the packed artifact using the documented consumer command and verify
its required runtime and peer dependencies in that isolated environment.
- When `doctor` checks an executable requirement, test its resolution on every
supported platform. Match the exact command-launch semantics rather than
assuming a platform's shell or extension-search behavior.
- Do not commit generated reference changes caused solely by a local
tool-version difference.

## Integrate an Upstream Harness Deliberately

When an adapter wraps a third-party SDK, executable, service, or embedded
runtime, establish the supported integration boundary before relying on it:

- Identify the exact upstream release, required runtime, and documented
installation path. Verify that path in an isolated consumer environment;
do not infer it from a development workspace's dependency layout.
- Check whether required upstream packages and executables can be resolved
before loading them. Report a missing requirement differently from a
dependency that was found but failed during import or initialization.
- Decide whether the harness may discover project files, user-home
configuration, plugins, instructions, or credentials. If Fabric does not

Use NeMo Fabric for both product references.

The changed text uses standalone Fabric for the product. The path instruction requires NVIDIA NeMo Fabric on first use and NeMo Fabric thereafter. Replace both occurrences.

When applicable, add focused evidence for the decisions above:

- Run a real-harness regression with temporary project and user-home inputs
when configuration discovery could affect a Fabric runtime.
- For a stateful harness, make a later result observably depend on an earlier
invocation; a test that merely invokes twice does not prove continuity.
- Test a configured external endpoint against a local deterministic server when
its security or forwarding behavior is adapter-owned.

Sensitive Data Exposure

CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Require credential-safe transport evidence for authenticated upstream endpoints. A local HTTP server does not test encrypted transport, certificate validation, or redirect handling. When the adapter owns the connection, require those checks and ensure redirects do not forward credentials to another origin. Preserve the existing SDK-owned loopback transport contract.

- When a live-provider check is intended to be provider-agnostic, do not
hard-code a vendor or model.

Do not claim automated NeMo Fabric conformance until the published conformance
suite exists and the exact adapter release passes it.
