Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The design changes cluster provisioning to discover, validate, and asynchronously install add-on operators, but currently leaves several high-impact behaviors unresolved, including accidental tenant visibility, dependency ordering, duplicate installations, sensitive or oversized error reporting, misleading health status, mutable operator selection, and silent loss of requests during version skew.

Verdict: A well-structured design that demonstrates deep familiarity with OSAC patterns and provides thorough implementation detail, held back by a placeholder graduation criteria, a test plan inconsistency, and unaddressed Documentation/UI cross-cutting dimensions. Feedback: Fix the unit test description that references package_name/channel proto validation — these fields are explicitly not in the API proto per your own design, so the unit tests should describe validating the fields that ARE in the proto (title, description, version constraints, exclusions, dependencies). Replace the placeholder graduation criteria with concrete, measurable conditions (e.g., 'All CRUD operations pass e2e, order-time validation covers all 5 error paths, degraded recovery verified in CI'). Address or explicitly defer the Documentation and UI cross-cutting dimensions — both are relevant since this introduces a new API surface with CPA/TA/TU workflows. Critical (0)None. Important (6)

Verdict: A thorough, well-structured design that follows established OSAC patterns across all four criteria, with deep implementation detail (proto schemas, Go types, Ansible playbooks), clear scope boundaries, specific test scenarios, and sound architectural decisions justified against existing precedents. Feedback: The Ansible playbook's rescue block contradicts the prose: the Failure Handling section says 'the playbook continues with remaining operators' but the loop has no ignore_errors, so it stops on first failure — reconcile the code with the prose or restructure the loop to use per-operator error handling with result tracking. The Observability section states 'No new observability changes' but a new API resource and AAP job type would benefit from Prometheus metrics (installation duration, success/failure counts) to help CPAs monitor at scale without inspecting individual ClusterOrders. Consider adding a brief Terminology section (following the Networking EP pattern) to define AddOnOperator, exclusion, dependency, and published-state semantics upfront. Critical (0)None.

- Around line 205-210: Require min_ocp_version to be less than or equal to

- Around line 720-726: Update the Version Skew Strategy so deployments fail
closed when osac-operator or its CRD does not support add_on_operators, rather
than allowing unknown addOnOperators data to be silently ignored. Implement
either an explicit compatibility gate that blocks incompatible deployments or
persistence of a pending installation request until a compatible consumer is
available, ensuring requested operators cannot be reported as Ready while
dropped.

Set new records to published=false.
The publication default is still unresolved while auto-discovery creates records. If creation defaults to true, every new role becomes tenant-visible before CPA review. Set the default in the API or persistence layer, then require an explicit CPA update to publish an operator.

Keep catalog visibility consistent with operator visibility.
A catalog item can retain an add_on_operators reference after the operator is unpublished or scoped to another tenant. Catalog browsing can still show the reference, while cluster creation later fails during order-time visibility validation. Validate references on catalog-item writes and on published or tenant changes, or define atomic stale-reference handling.

Install dependencies before dependent operators.
Dependency resolution produces a set, but the AAP loop does not define a dependency order. A dependent operator can run before its dependency and fail even though order-time validation passed. Carry a deterministic dependency-first order into ClusterOrder, or topologically sort before installation. Add a transitive dependency test.

Reject inverted OCP version ranges.
The design validates semver format but does not require min_ocp_version <= max_ocp_version when both values are set. An inverted range can publish successfully and make every order fail. Add cross-field validation in the Pydantic model and API update path.

Carry an immutable operator identity into ClusterOrder.
ClusterSpec.add_on_operators contains id and name, but ClusterOrderSpec.addOnOperators keeps only the name and later resolves a role by that name. A record or role can change between order validation and the delayed AAP job. The design also allows deletion of records referenced by in-progress orders. Store an immutable resource ID plus role revision or digest, or revalidate the exact resource before launch.

Make AAP job launch idempotent across controller restarts.
The no-duplicate claim only holds after the job reference reaches status.addOnOperatorJobs. If the controller crashes after AAP accepts the job but before status persists, the next reconcile can launch a second job. Use a deterministic idempotency key based on the ClusterOrder UID and installation generation, then query and reuse that AAP job.

Sanitize and bound AAP error text before persisting it.
The design copies raw result_traceback into AddOnOperatorsReady and JobStatus.Message, which are exposed through the API and oc describe cord. Ansible failures can contain module arguments, URLs, or secret values, and a large traceback can make status updates fail.

| **Interaction with PR #227 (OSAC-1604, Granular Cluster Status Reporting):** | ||
| PR #227 redesigns the feedback controller with a table-driven map and also | ||
| maps HyperShift-driven degradation (partial NodePool failures) to `DEGRADED`. | ||
| If #227 lands first, add-on operator failures become a second independent | ||
| source of `DEGRADED`. The two sources are distinguishable by `Reason` — the | ||
| implementation should use a distinct reason (e.g., `AddOnOperatorsFailed`) | ||
| so consumers can tell operator installation failures apart from node health | ||
| issues. If this design lands first, the mapping should be built to | ||
| accommodate #227's table-driven approach. |

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Aggregate DEGRADED sources instead of clearing the condition on add-on success.
The mapping makes AddOnOperatorsReady=True emit DEGRADED=False. If a NodePool or HyperShift degradation is active at the same time, that write can clear an unrelated failure from the shared DEGRADED condition. A distinct Reason does not prevent this if the proto exposes one aggregate condition. Make the feedback controller combine all sources, or emit only the add-on failure contribution, and add a mixed-source test.

394 - 413, The feedback controller’s AddOnOperatorsReady mapping must not clear
an existing aggregate DEGRADED condition when add-ons become ready. Update the
mapping around feedback controller condition aggregation to preserve or combine
active HyperShift/NodePool degradation, or emit only the add-on failure
contribution, and add a test covering simultaneous add-on and NodePool
degradation.
| ## Version Skew Strategy | ||
|
|
||
| The fulfillment-service and osac-operator are deployed together via | ||
| osac-installer. Version skew is limited to the deployment window. In either | ||
| direction, the unknown/unpopulated `addOnOperators` field is safely ignored | ||
| (Go JSON unmarshalling skips unknown fields), so operators simply aren't | ||
| installed until both components are upgraded. |

Fail closed when the consumer does not support add_on_operators.
The stated skew behavior allows the fulfillment service to accept an operator set while an older osac-operator or CRD ignores it. The cluster can reach Phase=Ready with the requested operators silently dropped, and the old order data may not be recoverable after upgrade. Gate incompatible deployments, or persist a pending installation request until a compatible consumer is available.

720 - 726, Update the Version Skew Strategy so deployments fail closed when
osac-operator or its CRD does not support add_on_operators, rather than allowing
unknown addOnOperators data to be silently ignored. Implement either an explicit
compatibility gate that blocks incompatible deployments or persistence of a
pending installation request until a compatible consumer is available, ensuring
requested operators cannot be reported as Ready while dropped.

There was a problem hiding this comment.
After #228 ClusterCatalogItem.fields would then govern it through an AddOnOperatorReferenceListFieldPolicy, rather than adding a plain repeated add_on_operators field directly to ClusterCatalogItem. During cluster creation, the selected list would be materialized into ClusterSpec.add_on_operators.
This shouldn’t be a problem, just something to keep in mind when implementing the two designs.

What controller, ClusterOrder or a new one? I would recommend adding a specific purpose reconciler for addOnOperators

Yes, we will use a separate controller for addOnOperators. I updated the doc to state it more explicitly

@trewest I'm missing the part where a user can retrieve "what add on operators are installed in my cluster?". Not requested, but something like status. Is this left out on purpose? |

@rccrdpccl It was not left out intentionally but made me realize we were missing a way to retrieve granular per-operator statuses and messages. Updated the design to support concurrent operator installation, status tracking and feedback to fulfillment-service |

…, and migration (osac-project#726) ## Summary - Add the `AddOnOperator` resource to the fulfillment-service API. - Provide private CRUD and `Signal` APIs plus public read-only `List` and `Get` APIs. - Store add-on operators as shared platform data; public visibility is controlled by `published`. - Add SemVer-compatible range validation, including OCP shorthand such as `4.17`, and `ADDON_OPERATOR_DEFAULT_PUBLISHED` support. - Add persistence, active-object tracking, name uniqueness, event payloads, reference lookups, and generated clients. ## Scope This PR intentionally supports shared platform operators only. Add-on operators are owned by the `shared` metadata tenant and are visible to all tenants when published. Tenant-specific visibility scopes are deferred to a follow-up design and implementation so the initial resource can use the existing metadata tenancy and reference-resolution model. ## Deferred - Tenant-specific operator visibility and scope-aware operator references. - Reverse-reference deletion and unpublish protection for future catalog-item links ([OSAC-4715](https://redhat.atlassian.net/browse/OSAC-4715)). - Catalog-item and cluster attachment/order-time operator resolution. ## Test Plan - Private CRUD, signaling, shared ownership, publication defaults, and SemVer-compatible range validation. - OCP shorthand version coverage such as `4.17` and `4.18`. - Public published filtering and read access. - Migration table creation, shared-tenant ownership, uniqueness, soft deletion, foreign keys, and immutability. - Generated protobuf clients for fulfillment-service, osac-operator, and metering-service. - Focused unit tests, migration tests, linting, and generated-code checks. ## Design [OSAC-4090 Add-On Operator Support](osac-project/enhancement-proposals#226) --------- Signed-off-by: Trey West <trwest@redhat.com>

sets (mutual exclusivity, OCP version constraints, dependency resolution), and a
separate AAP job for operator installation after cluster provisioning. Installation
status is tracked via a non-gating
