[HYPERSHELL-78][HYPERSHELL-96] fix(control-plane): GC Event namespace and e2e reaper

[squizzi]

Fixes periodic namespace GC failing after events:create RBAC was granted: recordGCEvent now sets involvedObject.namespace to the control-plane namespace so the apiserver accepts the Event. Adds unit coverage for that field alignment. Kind e2e seeds a synthetic orphaned namespace after gateway provisioning (30s reaper interval in the Kind overlay) and validates periodic reap plus a GarbageCollected Event in step 11 while steps 3–10 run in parallel with the reaper. Updates e2e-testing.spec.md and adds E2E_ORPHAN_GC_TIMEOUT.

Test plan

• go test ./components/control-plane/internal/reconciler/...
• E2E_INFRA_DRIVER=kind bash tests/e2e/e2e-openshell.sh

Summary by CodeRabbit

• Bug Fixes

  • Restricted gateway namespace garbage collection to eligible gateway workloads.
  • Prevented managed database namespaces from being unintentionally removed.
  • Improved garbage-collection events with complete API version and namespace metadata.

• Tests

  • Expanded end-to-end coverage for orphan and delete-triggered namespace cleanup.
  • Added validation for cleanup events and retained database namespaces.

• Chores

  • Shortened cleanup intervals in Kind-based test environments.
  • Added configurable timeout and diagnostics for orphan cleanup verification.

Walkthrough

The reconciler now limits namespace GC to gateway workload namespaces and records complete involved-object references on GC events. Kind and E2E tests cover periodic orphan cleanup and delete-driven namespace cleanup.

Changes

Namespace garbage collection

Layer / File(s)	Summary
Gateway namespace scope and deletion components/control-plane/internal/gateway/namespace.go, components/control-plane/internal/gateway/namespace_test.go	GC now accepts managed gateway namespaces and excludes ManagedDatabase namespaces. Tests cover classification and deletion retention.
Reconciler filtering and GC events components/control-plane/internal/reconciler/namespace.go, components/control-plane/internal/reconciler/namespace_test.go	The reconciler applies gateway-only filtering. GC events now include API version and control-plane namespace fields. Tests verify both behaviors.
Periodic orphan GC E2E validation deploy/kind/kustomization.yaml, tests/e2e/lib.sh, tests/e2e/e2e-openshell.sh	Kind uses 30-second GC settings. E2E tests seed backdated orphan namespaces, verify deletion and GarbageCollected events, and collect focused GC logs.
GC requirements and E2E specification specs/platform/openshell-gateway-namespace-gc.spec.md, specs/platform/e2e-testing.spec.md	Specifications define gateway-only periodic GC, database namespace exclusion, event recording, and E2E timing settings.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 42b63

The change is merge-ready after normal checks; only a non-blocking clarification to the documented namespace-matching rule remains.

Amber Analysis

This change set aligns GC Event involvedObject with Kubernetes validation, scopes periodic and delete-driven GC to gateway-prefixed namespaces (not openshell-db-*), and adds Kind e2e coverage for the periodic reaper. Prior findings (spec requirement scope, DeleteManagedNamespace label-only delete, e2e annotate race, Kind comment) are addressed.

Overall assessment: APPROVE
Confidence: High

No remaining Blocker, Critical, or Major findings. I did not re-flag the CodeRabbit APIVersion test request; TestRecordGCEvent_InvolvedObjectNamespaceMatchesEventNamespace now asserts v1.

Findings Summary (ordered by severity, highest first):

None.

Convention Checklist (omit conventions not applicable to the diff):

Convention	Result
No panic() in production code	Pass
Errors wrapped with fmt.Errorf context	Pass
errors.IsNotFound handled for 404 scenarios	Pass
No secrets in logs or responses	Pass
Proper context propagation (no context.TODO())	Pass
Reconcile pattern used (not create-or-skip)	Pass
Conventional commit messages	Pass
Input validated	Pass

Clarify the GC namespace grammar.

The implementation intentionally uses prefix-only matching to support pre-existing orphan namespaces, and the E2E fixture intentionally uses a non-hex name. Update the GC specification to state this rule explicitly: managed openshell-* names are eligible, except openshell-db-*; <hex> describes API-generated names.
