Pull request overview

Adds a new role primitive to the operator-component-framework to manage Kubernetes rbac.authorization.k8s.io/v1 Role resources using the same builder/mutation/flavor patterns as existing primitives, plus supporting docs and an example.

Changes:

Introduces pkg/primitives/role (resource, builder, mutator, flavors) and associated unit tests.
Adds a shared PolicyRulesEditor under pkg/mutation/editors for typed .rules manipulation.
Adds an end-to-end example (examples/role-primitive) and documentation (docs/primitives/role.md) for the new primitive.

Claude Review Cycle 1 Complete

Addressed:

Added pkg/primitives/role entry to the Built-in Primitives table in docs/primitives.md so the new primitive is discoverable from the documentation index.

Intentionally ignored:

Capabilities table formatting (role.md line 13): The table already uses correct single-pipe Markdown formatting — no double || exists. False positive.
gofmt formatting (policyrules_test.go lines 63, 79): gofmt -d reports no diff — the file is already correctly formatted. False positive.

Claude Review Cycle 2 Complete

Addressed:
None — all comments were evaluated and determined to be either invalid or not actionable within the scope of this PR.

Intentionally ignored:

policyrules_test.go lines 64 and 80 ("syntax error in composite literal"): False positive. The Go syntax is correct — rbacv1.PolicyRule{...}, with a trailing comma before the closing ) is valid Go. Confirmed by successful go build ./... and go test ./....
mutator.go line 26 ("beginFeature() won't be called between mutations"): Technically accurate that the unexported beginFeature() method prevents satisfying the FeatureMutator interface from outside internal/generic. However, this is the exact same pattern used by the existing configmap and deployment primitives. The role primitive correctly follows the established codebase convention. This is not a role-specific issue to address here.
docs/primitives.md line 125 ("PR description says no shared files modified"): Valid observation about the PR checklist description, not a code issue. The PR description could be updated to reflect that docs/primitives.md and pkg/mutation/editors/policyrules.go are new shared additions.

Addressed:

NewPolicyRulesEditor nil guard (policyrules.go:22): Added nil panic guard with descriptive message, matching ConfigMapDataEditor pattern. Added unit test for the panic behavior.
Docs EnableSecretAccess reference (role.md:286): Replaced EnableSecretAccess with EnableTracing to match the actual ExampleAppSpec fields used in examples/role-primitive.

Intentionally ignored:

Test syntax issue (policyrules_test.go:63): The code is valid Go. The } closes the struct literal and ) on the next line closes the AddRule call — this compiles and runs correctly. No change needed.

Addressed:
None

Intentionally ignored:

role.md table formatting (line 13): The tables in docs/primitives/role.md already use standard single-pipe markdown format, identical to docs/primitives/configmap.md. The claim about "double leading pipes" does not match the actual file content — the tables render correctly on GitHub.
Shared files modification (primitives.md line 134): The changes to shared files (docs/primitives.md — one row added to the primitives table; pkg/mutation/editors/policyrules.go — a new shared editor) are minimal and necessary to register the new primitive. This is a PR description/checklist accuracy concern, not a code quality issue. The PR description checklist can be updated separately if needed.

Address Copilot review comment requesting integration tests for Identity/Object/Mutate/ExtractData, mirroring the existing ConfigMap resource_test.go coverage. Tests cover baseline mutation, feature-gated mutations, feature ordering, custom field applicators (success and error), deep-copy safety, and data extractor error propagation.

- Add nil panic guard to NewPolicyRulesEditor for consistency with NewConfigMapDataEditor - Add unit test for nil panic behavior - Fix docs referencing non-existent EnableSecretAccess field (use EnableTracing to match example code) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Initialize the first feature plan inline instead of calling beginFeature(), matching the fix applied to deployment and configmap mutators. This prevents an empty feature from being created when the generic helper in mutator_helper.go calls fm.beginFeature(). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Align with architectural change in main where FeatureMutator interface now requires exported BeginFeature() instead of unexported beginFeature(). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Addressed:
None

Intentionally ignored:

pkg/mutation/editors/policyrules_test.go:80 - Copilot flagged a supposed brace/paren mismatch in the append call. This is a false positive. The syntax is valid Go: rbacv1.PolicyRule{...} is the struct literal closed by } on the same line, followed by , as the append argument separator, and ) closing the append( call on the next line. The code compiles successfully and the test passes.
