Explanation
The title "✨ add template.metadata to ClusterObjectDeployment" matches the main change. The diff adds spec.template.metadata (labels and annotations) to ClusterObjectDeployment, propagates it to each ClusterObjectSet revision, and uses the ✨ prefix that the template requires for minor, compatible changes. The title is specific and concise. It omits the validation behavior, but the title does not need to cover every detail.
Full details: Description check
-
Explanation
The description follows the repository template. It gives a clear summary and motivation: a generic spec.template.metadata that propagates to every ClusterObjectSet revision, with the controller staying agnostic to the keys. It explains the behavior (template-hash override, hashing and omitzero, 32-property and 256 KiB limits), the validation with the InvalidSpecification reason, and the testing done (unit, envtest, experimental e2e). The Reviewer Checklist is not ticked, and the description does not link a related GitHub issue. These are minor gaps, so the check passes.

- Line 72: Resolve the optionalfields lint failure for
ClusterObjectDeploymentTemplate.Metadata while retaining its value type and
omitzero tag; make the field’s optionality explicit in validation, or add a
narrowly scoped lint exception if empty metadata is valid.
- Around line 92-93: Update the Annotations validation on
ClusterObjectDeployment to enforce the combined UTF-8 byte size of all
annotation keys and values against Kubernetes’ 256 KiB total annotation limit.
Replace the per-value CEL size check with validation that counts bytes, not
string code points, and includes every annotation.
- Around line 85-86: Validate template labels at the deployment boundary using
Kubernetes label-key and label-value rules, and report invalid template metadata
before attempting revision creation. Locate the template metadata Labels field
and the revision-creation flow; ensure invalid labels such as keys with multiple
slashes are rejected before propagation to a ClusterObjectSet.

You're not doing this for Annotations (which is a direct close), in case it's missing?
There was a problem hiding this comment.
annotations is just cloned and placed directly in the COS annotations. There's nothing to mutate. With the labels, we need to add the template hash label.

[P2] Bound this diagnostic before writing status. ValidateLabels includes the rejected value in its error. A 40,000-character ASCII label value is accepted by the nested template schema, but produces a 40,109-byte condition message here. I reproduced this against envtest: Status().Update is rejected with status.conditions[1].message: Too long: may not be more than 32768 bytes, so the promised Progressing=False/InvalidSpecification condition is never persisted.
Please summarize oversized rejected values and cap the complete diagnostic, with a regression test that writes status through the API server.

Fixed in 5e5883a. Two changes:
setConditionnow caps every condition message at 1024 bytes (UTF-8-safe,...[truncated]marker) — well under the API server's 32768-bytemetav1.Condition.messagelimit — so a status write can never be rejected for an oversized message, for this condition or any future one.validateTemplateMetadatanow omits any rejected label/annotation value longer than 64 bytes, replacing it with<N bytes omitted>instead of echoing it, so the diagnostic stays readable (field path + reason + size).
Covered by unit tests: Test_validateTemplateMetadata asserts an oversized value is omitted rather than echoed, and Test_setCondition_capsMessage asserts the message cap.

Add a generic spec.template.metadata (labels + annotations) to the ClusterObjectDeployment template, mirroring orb-operator's ClusterObjectDeploymentTemplateMetadata, and propagate it verbatim onto every ClusterObjectSet revision the controller creates. This is the Kubernetes Deployment.spec.template.metadata -> Pod pattern. It lets a ClusterObjectDeployment carry arbitrary per-revision metadata (e.g. bundle annotations) down to its revisions without the controller knowing what the keys mean. buildClusterObjectSet clones the template metadata onto each revision and stamps the controller-managed template-hash label last so it always wins over a caller-supplied value. Because metadata is part of the hashed template (and omitzero), a metadata change cuts a new revision while a metadata-less deployment keeps the same hash (no re-rollout churn). Labels and annotations are each capped at 32 properties (MaxProperties) at the CRD, matching orb. Because the metadata is propagated verbatim onto each revision's ClusterObjectSet, the reconciler validates spec.template.metadata against the API server's own label/annotation rules (label key/value format, annotation key format, and the total annotation size limit); invalid metadata sets Progressing=False with reason InvalidSpecification and a user-facing message and skips revision creation, so the error is actionable on the ClusterObjectDeployment instead of silently stalling at ClusterObjectSet creation. Includes unit coverage (propagation, template-hash override, hash participation, no-churn, empty metadata, invalid-metadata InvalidSpecification including combined annotation size over the total limit), CRD validation tests, and experimental e2e scenarios for propagation and invalid metadata.

Because the metadata is propagated verbatim onto each revision's
ClusterObjectSet, invalid labels/annotations would otherwise be rejected by the API server at revision creation and silently stall the rollout.

On invalid metadata it setsProgressing=Falsewith reasonInvalidSpecificationand a user-facing message, and skips revision creation — so the error is actionable on theClusterObjectDeploymentitself.Testing
