WalkthroughThe change adds alert-rule preview, single-rule update, and single-rule delete APIs. It centralizes rule mutation planning, ownership checks, desired-object generation, and non-atomic update handling. Unit, router, parity, and end-to-end tests cover the new flows. ChangesAlert rule management
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR adds alert-rule previews and refactors create/update planning, but valid restore previews may fail with a server panic and some updates may apply label changes that the preview does not show. These correctness risks should be fixed before merging. Sequence Diagram(s)sequenceDiagram

143-146: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winReturn the response body for non-200 preview responses.
On a non-200 status the helper discards the body and returns
(status, nil, nil). Callers such aspreviewCreateWithTokenreport only the numeric status. When an RBAC case returns an unexpected status, the server message is lost, and the failure is hard to diagnose.
createRuleViaAPIat Lines 93-99 already includes the body in its error. Align the preview helper with that behavior.♻️ Proposed change to preserve the server message
if resp.StatusCode != http.StatusOK { - _, _ = io.ReadAll(resp.Body) - return resp.StatusCode, nil, nil + body, readErr := io.ReadAll(resp.Body) + if readErr == nil && len(body) > 0 { + log.Printf("preview returned %d: %s", resp.StatusCode, string(body)) + } + return resp.StatusCode, nil, nil }An alternative is to widen the signature to return the raw body, so each caller can include it in its own

Inline comments:
In `@api/openapi.yaml`:
- Around line 161-177: Declare the repository’s existing authentication security
scheme globally in the OpenAPI document, or explicitly on POST /rules/preview
and the related new single-rule operations, so authenticated access is required
and the documented 401/403 responses are consistent.
In `@docs/alert-management.md`:
- Around line 45-49: Update the API overview table to add the preview operation
using POST /api/v1/alerting/rules/preview, then add a concise preview section
stating that it does not persist changes and documenting writable, managedBy,
resources, and desiredRule.
In `@pkg/management/plan_arc_mutation.go`:
- Around line 88-100: Update computeARCRestoreMutation to return
arcMutationResult{noOp: true} immediately when existingArc is nil, before
accessing existingArc.Spec.Configs; preserve the existing filtering and deletion
behavior for non-nil ARC values.
In `@pkg/management/plan_create_platform.go`:
- Around line 94-107: Update createPlatformPlan.toRuleChangePlan to return both
the plan and an error, propagate the error from alertingRuleDesiredObject
instead of discarding it, and return no plan on failure. Adjust
PreviewAlertRuleCreate to handle and propagate the new return signature while
preserving the existing successful preview behavior.
In `@pkg/management/preview_alert_rule_test.go`:
- Around line 80-82: Make the create-preview persistence assertion meaningful in
the test using mockRules: initialize UpdateFunc before invoking the preview and
track whether it is called, then assert the flag remains false; also configure
and verify CreateFunc remains uncalled, confirming preview does not persist
through either update or create.
Apply the same fix in `@pkg/management/platform_update_parity_test.go` around
lines 348 - 365: The parity fixture can persist through
PrometheusRules().Update, which is not currently tracked.
In `@pkg/management/rule_changes.go`:
- Around line 210-225: The alertingRuleEnabledChange helper fabricates
CurrentValue and reports changes for no-op requests. Update
planDropRestoreChange to pass the actual current drop state into
alertingRuleEnabledChange, then have the helper return no entries when that
state already matches enabled; otherwise use the passed state as CurrentValue
and enabled as NewValue.
In `@pkg/management/update_alert_rule_labels.go`:
- Around line 95-101: Update applyUserDefinedLabelMap and
diffLabelSemanticChanges to use the same shared filter for provenance labels,
ensuring labels excluded from semantic diffs cannot be modified through the
write path; preserve normal user-defined label updates and return the existing
validation error behavior for invalid protected-label changes.
In `@pkg/management/update_platform_alert_rule_test.go`:
- Around line 595-608: Update the assertions after UpdatePlatformAlertRule in
the test around createdARC so AlertRelabelConfig creation is mandatory rather
than conditional. Fail when createdARC is nil, then verify the protected
alertname label is absent and the allowed new_label is present with value
new_value, proving the update applied while filtering only the protected label.
In `@test/e2e/preview_alert_rule_test.go`:
- Around line 282-297: Update the single-rule cache synchronization setup so it
waits for ruleInY, ruleInZ, and ruleInY2 before the single-rule update cases use
them. In test/e2e/preview_alert_rule_test.go lines 282-297,
test/e2e/single_alert_rule_test.go lines 317-349, and
test/e2e/single_alert_rule_test.go lines 141-145, adjust the
waitForSingleUpdateCacheSync flow and its callers as needed; preserve the
existing expected 403/200 assertions.

Reject unprotected provenance labels on the write path.
isProtectedLabel omits four labels that diffLabelSemanticChanges excludes. applyUserDefinedLabelMap can change these labels, and a request that also changes a normal label can persist the unpreviewed changes. Use one shared filter for both paths.

Wait for all rule IDs before the single-rule update cases. waitForSingleUpdateCacheSync waits only for ruleInY, but later cases use ruleInZ and ruleInY2. If the relabeled-rules cache has not included either ID, those requests can return 404 instead of the expected 403 or 200. Wait for all three IDs.

Add POST /api/v1/alerting/rules/preview for create and update dry-run. Share planning logic with execute paths, return multi-resource change plans with desiredObject, and add unit plus e2e RBAC coverage. Fix golangci-lint: remove unused helper, switch on managedBy, simplify ObjectMeta field access. Signed-off-by: Shirly Radco <sradco@redhat.com> Co-authored-by: AI Assistant <noreply@cursor.com>
