docs: add NICo upgrade guide

[shayan1995]

Summary

• Adds docs/manuals/upgrade.md — a comprehensive guide for upgrading an existing NICo installation using setup.sh
• Documents per-phase idempotent behavior on re-run, what is preserved vs. what changes, pre-upgrade checklist, timing estimates, and post-upgrade verification
• Includes detailed 2.0→2.1 version-specific notes covering the MetalLB CRD ownership migration (fix from fix(helm-prereqs): re-apply MetalLB CRDs after helmfile sync to survive 2.0→2.1 upgrade #4997), DPF version update, and startupProbe requirement (bug(machine-a-tron): scale-mode pod is liveness-killed during init above ~2,300 hosts (registers hosts before binding redfish port) #4298)
• Covers rollback procedure with PostgreSQL snapshot command and per-component upgrade recipes
• Wired into docs/index.yml under Getting Started > Installation Options and cross-linked from helm-prereqs/README.md and the Quick Start Guide

Validated on dev6: the 2.0→2.1 MetalLB upgrade path described in the doc matches what was tested and confirmed working with #4997.

Closes #5012

Test plan

• Docs render correctly in the Fern doc site (check index.yml wiring)
• All relative links resolve (../manuals/upgrade.md from quick-start.md)
• Version-specific MetalLB notes match the behavior of setup.sh post-fix(helm-prereqs): re-apply MetalLB CRDs after helmfile sync to survive 2.0→2.1 upgrade #4997

Walkthrough

This PR adds PR scan-range resolution, DPU UEFI password staging and rotation, site-explorer coordination, network-adapter discovery, REST API updates, Helm upgrade handling, PXE network readiness checks, and broad workflow and test changes.

Changes

CI and deployment workflows

Layer / File(s)	Summary
PR scanning and workflow actions .github/ci/*, .github/workflows/*	PR scan ranges now resolve through GitHub API data and merge-base calculation. Workflows use the dsx-ai-factory action fork and explicit scan revisions.
Upgrade and deployment configuration helm-prereqs/*, bluefield/charts/*, pxe/*	MetalLB CRD handling, DPF configuration injection, DPU-agent proxy configuration, and PXE NIC readiness behavior were updated.
Upgrade documentation docs/*, helm-prereqs/README.md	Installation upgrade procedures and DPF configuration behavior are documented.

DPU UEFI and credential rotation

Layer / File(s)	Summary
DPU UEFI API and CLI crates/rpc/proto/*, rest-api/proto/*, crates/admin-cli/*, crates/api-core/*	A SetDpuUefiPassword RPC and CLI command stage DPU UEFI credentials through Redfish. RBAC rules cover the new operation.
DPU UEFI controller flow crates/api-model/*, crates/machine-controller/*, crates/redfish/*	The controller selects eligible DPUs, resolves credential candidates, stages changes, restarts DPUs, records convergence, and handles quarantine and retry states.
BMC rotation coordination crates/credential-rotation/*, crates/*-controller/*, crates/api-db/*	BMC rotation now pauses site exploration, waits for acknowledgements, preserves rotation state during credential-store failures, and resumes site exploration transactionally.

Discovery and API behavior

Layer / File(s)	Summary
Network-adapter port inventory crates/bmc-explorer/*, crates/site-explorer/*, crates/api-model/*, crates/rpc/*	Linked Lenovo chassis ports now provide deduplicated MAC inventory. Port data remains distinct from system Ethernet interfaces.
Machine interface reconciliation crates/site-explorer/src/machine_creator.rs, crates/api-db/src/predicted_machine_interface.rs	Zero-DPU reconciliation preserves settled primary interfaces, validates ownership, and adopts declared adapter-port interfaces.
REST API contracts rest-api/api/*, rest-api/db/*, rest-api/workflow/*, rest-api/openapi/*	Operating-system usability now supports provider-owned templated iPXE records. SKU creation timestamps and read-only Ethernet-device validation are propagated through storage, workflows, and OpenAPI.

Supporting runtime changes

Layer / File(s)	Summary
Configuration and state validation crates/api-core/src/cfg/*, crates/health/*, crates/host-support/*	DPF service overlays merge with defaults. Leak detection requires enabled resources. Agent configuration accepts defaults and machine-identity proxy settings.
Hardware and state tests crates/bmc-explorer/src/hw/*, crates/bmc-mock/*, crates/api-core/src/tests/*	Supermicro GB300 BIOS expectations, BOSS discovery transitions, and mock Redfish resources were updated and tested.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 635c8

The current head is not merge-ready: credential rotation can bypass unrelated suppressions or report success before a DPU restart applies the change, inventory reconciliation can expose provider-owned operating systems across provider boundaries, and malformed persisted data can panic the controller. The upgrade guide also misstates command scope and omits required post-upgrade checks. These create concrete security, correctness, and availability risks that should be fixed before merge.

Report invalid ADMIN_LOCK_ADMISSION values instead of falling back silently.

The parse chain discards two distinct operator errors. A non-numeric value (for example sixteen) and a clamped value (for example 0 or 1000) both resolve without any signal. The effective permit count then differs from the operator's intent, and the only symptom is throughput behaviour under load — the hardest place to diagnose it.

Emit the resolved value once at initialization, and warn when the supplied value is rejected or clamped.

Consider tolerating a transient get_revision failure until the deadline.

Model the revision state as an enum instead of comparing a string literal.

state is an Option<String> compared against the literal "applied" in apply_status. NVUE revision states are a known, finite vocabulary. The repository guidelines require modelling such values as an enum with Display and FromStr, rather than passing bare strings.

A dedicated enum with a catch-all for unmodelled values preserves the current behavior, which treats an unknown state as Pending, and removes the magic literal. The Display implementation also keeps the last_state field of NvueClientError::RevisionApplyFailed readable.

As per coding guidelines: "When a value has a known, finite set of possibilities, model it with an enum (or a struct of enums) and implement traits Display and FromStr — do not pass it around as a bare String or &str literal."

Consider extracting the timestamp normalization into a helper.

.UTC().Round(time.Microsecond) is applied independently in FromProto (Line 151), Create (Line 267), and Update (Line 383). The logic itself is correct in all three places.

Extracting a small helper, for example func normalizeCreated(t time.Time) time.Time { return t.UTC().Round(time.Microsecond) }, removes the duplication and gives one place to change if the rounding granularity ever needs to differ.

Consider threading serde_json::Map to remove the panicking downcast.

Every caller builds the values with serde_json::json!({ ... }), so the object invariant holds today. The expect still encodes that invariant at runtime rather than in the type system, and the repository's Rust guidelines discourage panicking operations. Accepting &mut serde_json::Map<String, serde_json::Value> and converting once at the ServiceDefinition boundary makes the invariant unrepresentable to violate. This is optional; the current form is sound.

As per coding guidelines: "Do not use a panicking operation — including unwrap(), expect(), panic!, assert!, or unreachable! — when failure can be caused by routine or malformed request data, persisted data, configuration, the network, hardware, or a recoverable dependency failure."

691-868: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Consider splitting this reconciliation into two helpers.

The logic is correct as written. The demote-before-adopt ordering protects the single-primary index, the selected_primary_has_real_row gate correctly avoids clearing a settled primary while the replacement exists only as a prediction, and the comment explaining why retained boot-interface ids are not copied into predictions documents a genuinely non-obvious decision.

The concern is maintainability. The function spans roughly 180 lines with four nesting levels, and it interleaves two distinct concerns: reconciling existing machine_interfaces rows and reconciling predicted_machine_interfaces rows. Extracting the two branch bodies of the loop into reconcile_owned_interface and reconcile_predicted_interface would let each invariant be read and tested in isolation without changing behavior.

One smaller readability note: min_by_key(|interface| interface.interface_type == InterfaceType::Bmc) appears at lines 709 and 741 and relies on false < true to prefer the non-BMC row. The intent is correct but not self-evident. A short comment, or a named helper such as prefer_non_bmc, would make the selection rule explicit at both sites.

Consider distinct PCI paths per NIC in the fixture.

The generated ids and the Boot0003 starting offset are correct, and the line continuation at lines 151-152 adds no stray whitespace to the device path.

One fidelity note: pci_path is a single shared literal, so the embedded 1G NIC and the DPU host NIC both advertise PciRoot(0x0)/Pci(0x10,0x0)/Pci(0x0,0x0) and differ only in the MAC segment. Real firmware reports a distinct PCI path per device. If any boot-order logic ever matches or deduplicates boot options by UEFI device path, this fixture would not expose that behavior. Varying one PCI function digit per NIC would keep the fixture representative at negligible cost.

♻️ Proposed fixture refinement

Unknown service names are silently discarded.

The _ => continue arm accepts any misspelled table name, for example [dpf.services.dpu_agnet], and keeps the compiled-in defaults. The operator then ships an unintended chart or image version with no diagnostic. This repository already treats config typos as parse failures elsewhere in this file (see secrets_config_rejects_misspelled_field). Reject the unknown key instead.

🛡️ Proposed fix

+        const SERVICE_NAMES: &[&str] =
+            &["dts", "doca_hbn", "dpu_agent", "dhcp_server", "fmds", "otel"];
         for (name, configured) in configured {
             let service = match name.as_str() {

Record convergence only after the DPU restart confirms the staged password.

uefi_setup(..., true, ...) only stages the BIOS setting. The setting commits on a later DPU restart. This code records DpuUefi convergence before that restart occurs.

The rotation engine can then treat the DPU as complete while it still has the old password. Keep this operation pending, and record convergence after the target DPU restart succeeds and confirms the applied setting.

This conflicts with the supplied ManagedHostState::RotatingDpuUefi contract, which defines the sequence as stage, restart, then record convergence.

Add a duplicate port-MAC regression test or define disambiguation.

explored_endpoints permits the same port MAC in rows with different addresses, while by_mac returns an owner only when exactly one row matches. Two reports with the same port MAC therefore return no owner.

Prevent foreign suppressions from opening the escape hatch

ensure_present preserves an existing unacknowledged operator row, including its old requested_at. The timeout must apply only when every unacknowledged row is rotation-owned. Otherwise, a stale rotation row for one MAC can allow the whole multi-MAC rotation to proceed while another MAC has only a foreign, unacknowledged suppression.

Include macs in the warning fields. Add tests for the timeout branch, including foreign-only and mixed-scope suppressions.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard the attempt arithmetic against a zero or non-integer poll interval.

SCOUT_NETWORK_POLL_INTERVAL is operator-tunable. $((network_wait_seconds / network_poll_interval)) raises a division-by-zero error when the value is 0, and a syntax error for a fractional value such as 0.5. Both abort the helper on the boot path with a shell diagnostic instead of a readable reason. Validate the two knobs before the arithmetic.

As per path instructions: review shell scripts for "strict-mode assumptions, error propagation".

🛡️ Proposed fix

+case "$network_poll_interval" in
+	''|*[!0-9]*|0) network_poll_interval=1 ;;
+esac
+case "$network_wait_seconds" in
+	''|*[!0-9]*) network_wait_seconds=60 ;;
+esac
 probe_attempts=0
 probe_max_attempts=$((network_wait_seconds / network_poll_interval))
 [ "$probe_max_attempts" -lt 1 ] && probe_max_attempts=1

In `@pxe/common_files/forge-scout-network.sh` around lines 71 - 73, Validate the
tunable network wait and poll interval values before the probe_attempts
arithmetic, rejecting zero, negative, non-integer, and otherwise invalid values
with a clear diagnostic and controlled exit. Update the initialization around
probe_max_attempts so division is only performed after validation, while
preserving the existing minimum-attempt behavior.

Enforce provider scoping in inventory reconciliation.

At rest-api/workflow/pkg/activity/operatingsystem/operatingsystem.go:716-722, reject associations when an existing provider-owned OS and the reporting Site have different InfrastructureProviderID values. Otherwise, a foreign TemplatedIPXE OS can become visible to the Site's tenants, and IsTenantUsable permits its use. Add a cross-provider regression test.
