Summary by CodeRabbit
WalkthroughThe change adds backend-neutral NVOS update contracts, implements durable RMS-backed submission, and updates rack maintenance to use the new manager with profile validation and explicit error classification. A DPF reprovisioning test now retains the configured rack ID. ChangesNVOS update submission
DPF reprovisioning test support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new backend-neutral NVOS update path deletes maintenance credentials before retryable failures are handled, which can turn transient update failures into terminal rack errors, and an interruption after backend acceptance could leave work untracked and risk duplicate updates. Merge should wait for these reliability issues to be addressed; telemetry and failure classification also need explicit follow-up. Sequence Diagram(s)sequenceDiagram

234-243: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winPreserve the ambiguous-outcome classification for this mutating call.
This branch maps every RPC failure to
Internal. The other mutating RMS submissions in this file (rms_ensure_switch_password_rotation,rms_batch_reset_switch_factory_default) classify ambiguous transport or deadline failures asOperationOutcomeUnknown, because RMS can accept the work before the local call fails. An NVOS image submission is destructive and reboots switches, so the same distinction applies here. Consider mappingUnavailable,DeadlineExceeded, andCancelledtoOperationOutcomeUnknown, keepingInternalfor failures that prove no dispatch occurred. If the classification is deliberate, the doc comment onNvosUpdateManager::start_nvos_updateshould state why a resubmission is safe.🤖 Prompt for AI Agents

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The unconditional token deletion makes the retryable branch unreachable.
Line 2760 deletes the rack maintenance access token before the result is classified. The comment on line 2763 states that Internal and RejectedBeforeDispatch stay handler errors so that Start is retried. On that retry, load_rack_maintenance_access_token at line 2646 runs again and finds no token, so the handler transitions the rack to Error with a credential-load message instead of the real submission failure. A transient RMS failure therefore ends the maintenance request terminally, and the surfaced cause is misleading.
Delete the token only on the paths that will not be retried, in the same way the firmware branch does at line 2289.
🐛 Proposed fix
- delete_rack_maintenance_access_token(ctx.services.credential_manager.as_ref(), id)
- .await;
-
// Invalid requests cannot succeed on retry. Backend submission
// failures remain handler errors so the Start state is retried.

- Ok(job) => job,
+ Ok(job) => {
+ delete_rack_maintenance_access_token(

This is a valid finding and is a pre-existing bug before this refactor. Tracking this issue separately in #5616 as this PR is scoped to refactoring.

@jayzhudev, thanks for confirming. Tracking the token-lifecycle fix in #5616 keeps this refactoring pull request focused.
