WalkthroughThe DPF SDK now deletes legacy unscoped DPUServiceInterfaces before creating scoped replacements. It waits for deletion, reports prolonged blocking, and returns migration errors. API core rejects unscoped startup when scoped interfaces remain. Documentation and tests cover the new behavior. ChangesDeployment-scoped ServiceInterface migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The migration changes startup cleanup and prevents unsafe mode changes, but scoped-interface detection can become incomplete when new deployment types are added, potentially allowing an unsafe revert to unscoped mode. The new delete API also lacks documented idempotency, creating integration ambiguity. These issues should be addressed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Centralize the scoped-interface suffix mapping.
crates/dpf/src/sdk.rs owns the exhaustive DpuDeploymentType suffix mapping, but scoped_service_interface_names duplicates its values. If the SDK mapping changes, the disabled-mode startup guard can miss scoped interfaces and allow unscoped, match-all resources. Expose a shared helper and preserve the -{suffix} boundary check.

Document the idempotent delete contract.
DpuServiceInterfaceRepository::delete is a new public trait method. Add a Rust documentation comment that states deletion succeeds when the resource is already absent. This preserves the retry contract for partial migration cleanup.

Kubernetes will mark the pod as ready while this blocks due to the liveness probe because the probe only checks metrics which starts early, but this blocks the API from starting.
This is the edge of my k8s knowledge, so it may not be important. What are the expectations for the API pod startup in this situation?
The relevant ordering in run.rs is:
- Metrics listener starts: line 111.
- setup_resources/DPF initialization: line 130.
- Main API listener starts: line 138.

you could also argue that the API needs a "readiness probe" in addition to a "liveliness probe", but again, you're at the limit of my k8s knowledge (and probably outside the scope of this PR)

This diff adds a one-way migration to deployment-scoped DPU service interfaces.
When scoped mode is enabled, NICo removes legacy unscoped interfaces, waits for DPF to finish deletion, then creates scoped replacements. After ten minutes it logs a detailed operator error but keeps waiting in the same startup attempt—no crash loop or repeated delete requests.
It prevents reverting to unscoped mode while scoped interfaces exist. The docs explain that the flag is read at startup, how manual cleanup completes the scoped migration, and how to return to unscoped mode safely.
It also adds repository delete support and tests for cleanup ordering, a stuck deletion continuing to wait, scoped detection, and documentation coverage.

Additional Notes
Currently there is a dpf bug that prevents unscoped interfaces from being deleted. The logs below show that the code now stops the migration if it can't delete the unscoped interfaces. Manual deletion allowed the migration to proceed.
