WalkthroughThe REST and Flow APIs now use Core rack and component identifiers. Flow UUIDs remain internal. Rack and component lookup, task filters, operation targets, models, tests, and OpenAPI documentation now use external identifiers. ChangesCore identifier migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change makes Core identifiers canonical at the REST boundary, but the current implementation can still drop Core rack and component identifiers during internal conversion, leaving persisted racks or round-tripped data unresolvable through the new API contract. Those correctness issues should be fixed before merge, and the breaking identifier migration requires coordinated rollout across clients and services. Sequence Diagram(s)sequenceDiagram

When an id filter is provided, this constructs an ExternalRef with the ID but leaves its type at COMPONENT_TYPE_UNKNOWN. Flow passes every operation target through ComponentTargetFrom, which rejects unknown external component types, so tray validation, power, and firmware operations using the newly advertised Core IDs fail before inventory resolution; the same type-less shape is used by the single-tray and slot-resolved handlers. Either resolve the ID to a typed target first or add an untyped, ambiguity-checked Core-ID target form.
Useful? React with 👍 / 👎.

Before we move forward with the review:
- Are the Rack IDs coming from RMS? Then there's no reason to highlight them as Core ID. It should be considered the unique identifier used across all of NICo. In descriptions we should say
Unique identifier for Rack within NICo - Are these Rack/Component IDs string names?
idandcomponentIdseems confusing. Can we remove one of them?- We don't want gRPC details leaking in REST e.g.
core.rack.rack_id

Preserve rack identifiers in inverse conversions.
ComponentFrom does not restore Component.RackExternalID, and RackFrom does not restore Rack.ExternalID from RackId. A protobuf-to-domain-to-protobuf conversion can clear both identifiers. Add both assignments and a round-trip test.

Propagate rack_id in the inbound protobuf conversion.
protobuf.RackFrom in rest-api/flow/internal/converter/protobuf/converter.go:239-271 does not assign r.GetRackId() to rack.Rack.ExternalID. A write request that contains a Core rack ID loses that ID before dao.RackTo persists the rack. Later external-ID lookups cannot resolve that rack.

REST currently exposes Flow's internal rack and component table UUIDs as public rack and tray identifiers. That leaks persistence details and makes the REST contract inconsistent with Core.
This change makes Core identifiers canonical at the REST boundary:
core.rack.rack_idcore.machine.idcore.switch.idGET /tray/{id}accepts either a Core component ID or the component BMC MAC addressFlow now resolves these external identifiers internally for inventory and task operations, while its table UUIDs remain implementation details. Existing lookup RPCs and request fields are reused: Core identifiers are resolved first, then legacy Flow UUIDs are accepted as a compatibility fallback. The REST models, handlers, OpenAPI specification, generated SDK, and published documentation use the same contract. The existing
componentIdresponse field remains as a compatibility alias and always equalsid.Component external IDs are unique only within a component type. An untyped lookup that matches more than one component returns an ambiguity error instead of selecting one; clients can use the component BMC MAC address to resolve that case.

Closes #5380
Type of Change
Breaking Changes
Rack and tray identifiers are no longer Flow UUIDs. Clients that persist or validate these identifiers as UUIDs must use the corresponding Core IDs instead. Tray lookup also accepts a component BMC MAC address. The OpenAPI breaking check reports the expected removal of the UUID format from the affected public fields.
Testing
Verified with:
Additional Notes
The Flow protobuf changes add only the Core identifier fields needed in responses. Rack and component lookups, task filters, and operation targets reuse their existing RPCs and request fields.
