✨: dedupe ClusterObjectDeployment template and ClusterObjectSet spec into shared content struct - #3146
Introduce ClusterObjectSetContent holding the phases, progressionProbes, and collisionProtection fields shared between ClusterObjectSet.spec and ClusterObjectDeployment's template spec.
Both spec structs embed it anonymously (json:",inline"), so the existing JSON paths (.spec.phases, .spec.template.spec.phases, etc.) are unchanged.
Content fields are strictly immutable from COS creation via struct-level CEL rules on the COS-only ClusterObjectSetSpec wrapper. Optional progression probes cannot be added, changed, or removed after creation; the COD template remains mutable.
The controller now copies the content struct directly when building a ClusterObjectSet from a template, making drift between the two shapes impossible by construction.
Shared field docs are context-neutral (following the PodTemplateSpec precedent), without component-specific GroupKind-to-phase recommendations.
Motivation
The ClusterObjectDeployment template and ClusterObjectSet spec duplicated the same three fields, risking drift. Mutability differs (template is mutable, COS spec is immutable), but that is a property of the CRD schema (CEL rules), not the Go struct — so a single shared structure can serve both.
Verification
make generate manifests crd-ref-docs — regenerated schemas, apply configurations, manifests, and API reference documentation. COS-only CEL rules enforce strict content immutability; COD templates have no content-immutability rules.
make test-unit — all tests pass, including TestClusterObjectSetImmutability and TestClusterObjectDeploymentTemplateIsMutable (mutates all three content fields + optional-field removal).
Watched the new omitted-to-set progression-probe regression fail before tightening CEL; it passes afterward. Probe removal is rejected, and lifecycle updates with unchanged or omitted probes remain allowed.
make lint, make lint-api-diff (no new issues), make verify — clean.
The automatic completeness guard for future ClusterObjectSetContent fields requested in this review thread is deferred to a separate follow-up PR. The current PR retains the field-specific behavioral regression tests.
Summary by CodeRabbit
New Features
Deployment templates now group phases, progression probes, and collision protection as shared content. Changes to template content create a new deployment revision, while existing revisions remain unchanged.
Bug Fixes
Cluster object set content—including phases, progression probes, and collision protection—must remain unchanged after creation. Progression probes can no longer be added, changed, or removed after creation.
Documentation
Updated API and resource descriptions to clarify phase grouping and readiness progression, probe behavior and limits, and collision-protection inheritance.
The API now groups phases, progression probes, and collision protection in shared content used by ClusterObjectSet and ClusterObjectDeployment templates. Validation, apply configurations, deep-copy methods, controller revision construction, fixtures, CRD schemas, and API reference material now use that structure.
Changes: Shared content contract and deployment revisions
Layer / File(s)
Summary
Shared content and validation api/v1/*, helm/olmv1/base/object-controller/crd/experimental/*clusterobjectdeployments.yaml, helm/olmv1/base/object-controller/crd/experimental/*clusterobjectsets.yaml, manifests/experimental*.yaml, docs/api-reference/olmv1-api-reference.md, docs/draft/concepts/clusterobjectsets.md
The API types embed shared content for phases, progression probes, and collision protection. ClusterObjectSet spec-level validations require these fields to remain unchanged, including preventing progression probes from being added or removed. Tests and CRD schemas reflect the nested shape and validation rules. The documentation describes the shared content and phase and probe behavior.
Deep-copy and apply configurations api/v1/zz_generated.deepcopy.go, applyconfigurations/api/v1/*, applyconfigurations/utils.go
Deep-copy methods copy the shared content and its slices. Apply configurations add a shared content type and route template and spec builder methods through it. ForKind maps the content kind to its apply configuration.
Copy deployment content into revisions internal/object-controller/controllers/*, internal/object-controller/status/status_test.go, internal/operator-controller/applier/boxcutter_test.go, internal/operator-controller/controllers/boxcutter_reconcile_steps_test.go, cmd/object-controller/main_test.go
buildClusterObjectSet copies shared content from the deployment template into the revision. Related test fixtures initialize phases and collision protection through the nested content field.
operator-framework/operator-controller#3073: Changes serialization for collision protection and list semantics for phase objects, contracts relevant to the shared content fields.

Merge Risk: Minimal · up to 4cfea
This refactor moves shared revision fields into a common struct while keeping the JSON API shape. No actionable merge-blocking risk was identified from the supplied evidence, though the maintainer hold on #3147 ordering still applies.

Can we make them immutable, period? Is there any circumstance where we would need to create a COS without phases/progressionProbes/collisionProtection set, and then later patch the COS to set them?
The reason will be displayed to describe this comment to others. Learn more.
Updated in 4cfea62: COS content is now immutable from creation. Phases and collision protection use strict equality; progression probes freeze both presence and value, so they cannot be added later or removed. The probes rule retains presence guards because the field is optional—ordinary updates with probes omitted on both sides must still work. The API-server-backed tests cover these transitions and confirm COD templates remain mutable.

Do you think there'd be a way for us to add a test that somehow verifies that all fields in the ClusterObjectSetContent struct are configured as immutable?
I'm thinking a unit test that parses the Go code, finds the json field names of the ClusterObjectSetContent struct, and then looks for comments on ClusterObjectSetSpec that match the pattern for the immutable CEL expressions for each of those fields.

I will handle the automatic field-completeness guard in a separate follow-up PR, keeping the field-specific behavioral regression tests here. The existing tests cover all three current fields, but do not automatically fail when a new content field is added. For the follow-up, I plan to enumerate the struct JSON fields with reflection and require an API-server-backed mutation case for each, so a future field without coverage fails the test. That would verify the generated validation behavior rather than depend on exact Go comment or CEL-expression spelling.

Removed in 4cfea62. The shared phases field no longer recommends GroupKind-based grouping or particular phase names; it retains only the API contract around readiness gating, unique names, and limits. Regenerated the apply configurations, CRDs, manifests, and API reference. Operator-controller-specific phase ordering remains in the concept guide rather than the shared API description.
…into shared content struct
Introduce ClusterObjectSetContent holding the phases, progressionProbes,
and collisionProtection fields shared between ClusterObjectSet.spec and
ClusterObjectDeployment template specs. Both spec structs embed it
anonymously (json:",inline"), preserving the existing JSON paths.
Immutability of the content fields is enforced via struct-level CEL rules
on the COS-only ClusterObjectSetSpec wrapper, so the COD template remains
mutable.

Make COS phases and collision protection strictly immutable. Freeze both
presence and values of optional progression probes from creation, while
allowing lifecycle and metadata updates with unchanged content. Keep the
shared COD template mutable and add API-server-backed regression coverage.
Remove component-specific phase recommendations from shared field docs and
regenerate apply configurations, CRDs, manifests, and API reference output.
