WalkthroughThis PR adds entity-type validation: new EntityTypeRegistry with owner-aware reference counting; a feature flag (ServerConfig/OperatorConfig.EntityTypeValidationEnabled); server-side registry initialization from cluster ContentConfiguration CRs and periodic refresh; router and HttpValidateHandler wiring to invoke ValidateEntityTypes when a registry is present; ContentConfigurationSubroutine changes to lazily init and update the registry, plus Finalize support; extended validation interface and regenerated mocks; and comprehensive tests for registry, validation, subroutine, and endpoint behaviors.

In `@cmd/server.go`:
- Around line 77-84: The startup code currently bulk-loads a snapshot via
initServerEntityTypeRegistry and hands that static
*validation.EntityTypeRegistry to server.CreateRouter, causing /validate to use
stale types; replace this with a live-updating registry or on-demand resolver:
implement a watch/informer (or a registry wrapper) that subscribes to
ContentConfiguration create/update/delete events and updates the in-memory
registry (or resolves the current set on each validation call), ensure
initServerEntityTypeRegistry becomes the bootstrap seed for the watcher and add
retry/health behavior on bootstrap failures so the handler never permanently
holds an incomplete registry; update cmd/server.go to pass this live
registry/resolver to CreateRouter and ensure validation.ContentConfiguration
consumers use the live view.
In `@pkg/subroutines/contentconfiguration.go`:
- Around line 114-127: The validator is currently run against r.entityRegistry
while it still contains this resource's prior definitions, causing stale types
and refcount inflation; before calling r.validator.ValidateEntityTypes with
validatedConfig, remove this resource's previous definitions from
r.entityRegistry, then load the candidate definitions (validate against registry
- previous + candidate), and only after successful validation apply the
remove/load transition to actually replace the registry entries (mirror this
same remove logic in the reconcile delete path so old definitions are cleaned up
on deletion); refer to r.entityRegistry, r.validator.ValidateEntityTypes,
validatedConfig, and the code that adds definitions (around the block that sets
instance.Status.Conditions) and apply the same fix for the other add/validate
block referenced (lines ~157-163).
- Around line 81-89: The registry bootstrap currently sets r.registryInitDone
true even when initEntityTypeRegistry fails because the Store(true) is executed
after the error check path returns; instead ensure registryInitDone.Store(true)
is only called after a successful initEntityTypeRegistry call and that the mutex
r.registryInitMu is unlocked in all code paths; propagate the init error (return
it) so the reconcile can retry rather than marking initialization complete.
Apply the same fix to the other bootstrap block referenced around lines 174-176
(use r.initEntityTypeRegistry, r.registryInitMu, and r.registryInitDone
consistently: lock, call initEntityTypeRegistry, on error unlock and return the
error without setting registryInitDone, on success set
registryInitDone.Store(true) then unlock).
In `@pkg/validation/entitytype.go`:
- Around line 57-74: Validate currently only checks r.types so entity types
defined in the same ContentConfiguration are treated as unknown; fix by merging
collectDefinedEntityTypes(cc) into the per-call lookup before checking
references: inside EntityTypeRegistry.Validate copy existing r.types into a
local map, add entries from collectDefinedEntityTypes(cc) (after
normalizeEntityType) into that local map, then use that combined map when
iterating refs from collectReferencedEntityTypes(cc); keep the existing RLock
for reading r.types and add a regression test ensuring a CC that defines and
references the same type (e.g., "project") passes validation.

Lines 107-108 validate against a registry that still contains this ContentConfiguration's previous definitions. Lines 151-154 only add the new definitions via
Load, without removing the old ones. This causes several problems:
- Stale types remain valid: Renaming or removing a
defineEntityleaves the old type in the registry, and validation incorrectly accepts references to it.- Refcount inflation: Repeated reconciles keep calling
Loadfor the same types, inflating reference counts.- No cleanup on deletion: When a ContentConfiguration is deleted, its definitions remain in the registry.
Before validating at line 107, remove this resource's previous definitions from the registry. After validation succeeds, apply a remove-then-load transition to replace the old definitions with the new ones. Additionally, ensure that ContentConfiguration deletion triggers removal of its definitions from the registry.

Three bugs in the entity type validation feature: 1. EntityTypeRegistry.Load was called on every successful reconcile, incrementing refcounts unboundedly. Replace Load/Remove with LoadForOwner/RemoveOwner/BulkloadWithOwners which track per-CC contributions via an owners map — repeated calls for the same owner are idempotent and spec changes are applied as a diff. 2. Deleted ContentConfigurations never had their entity types removed from the registry. Implement the subroutines.Finalizer interface on ContentConfigurationSubroutine so the lifecycle framework adds a finalizer to each CC and calls Finalize on deletion, which invokes RemoveOwner to clean up registry entries. 3. The server-side registry was a point-in-time snapshot loaded at startup. Add a refreshRegistryPeriodically goroutine that re-lists ContentConfigurations and calls Bulkload every 5 minutes.

ownerKeyfallback risks collisions across namespaces.When
UIDis empty (rare in practice, but possible in unit tests or apply-server short-circuits), the fallback iscc.Namespace + "/" + cc.Name. Two resources whosenamespace+"/"+namehappen to collide because the namespace contains a/cannot occur in Kubernetes, but mixing UID-keyed entries from real reconciles with namespace/name-keyed entries from tests within the same registry yields divergent owner identities for the same logical object.

In `@pkg/subroutines/contentconfiguration.go`:
- Around line 168-185: Finalize currently returns early when r.entityRegistry is
nil, leaving the entityTypeFinalizerName present and blocking deletion; update
Finalize to always attempt to remove the finalizer string (using
controllerutil.RemoveFinalizer or equivalent) from the passed obj even when
r.entityRegistry is nil, then perform the existing cleanup
(r.entityRegistry.RemoveOwner(ownerKey(instance))) only if entityRegistry is
non-nil, and finally return subroutines.OK() so the subroutines framework can
update the object and clear the finalizer; keep Finalizers() behavior unchanged
but ensure Finalize handles finalizer removal unconditionally for
ContentConfiguration instances.

In `@pkg/subroutines/contentconfiguration.go`:
- Around line 75-86: initEntityTypeRegistry currently swallows transient List
errors (see the List handling around the body of initEntityTypeRegistry) which
lets the caller mark registryInitDone true; change initEntityTypeRegistry so
that any failure from the API List call is returned (not just logged) and only a
fully successful initialization returns nil, ensuring the outer reconcile block
that calls initEntityTypeRegistry (and sets registryInitDone) only marks the
registry as initialized on success; update the error paths in
initEntityTypeRegistry (and any helper it uses for listing/loading, e.g.,
LoadForOwner) to propagate and return the error instead of swallowing it so
retries occur.

Nitpick comments:
In `@cmd/server.go`:
- Around line 154-176: loadRegistryFromCluster calls registry.Bulkload(configs)
which resets internal reference counts on validation.EntityTypeRegistry and
could silently clobber owner-contributed entries later; add a clear comment on
the server-side registry usage near loadRegistryFromCluster and the registry
construction stating it is only refreshed via Bulkload and must not be used
incrementally (i.e. do not call LoadForOwner or BulkloadWithOwners on this
instance), or alternatively create a distinct constructor (e.g.,
NewBulkOnlyRegistry) and use that here so intentions are explicit and accidental
incremental updates are prevented.
- Around line 178-189: refreshRegistryPeriodically currently polls every 5
minutes using loadRegistryFromCluster which allows up to 5 minutes of stale
EntityTypeRegistry state for ContentConfiguration changes; replace or supplement
this polling with a controller-runtime cache.Cache watch on ContentConfiguration
and hook handlers (e.g., LoadForOwner/RemoveOwner semantics) to update the
registry in real time, keeping the registry pointer in
refreshRegistryPeriodically (or the registry update path used by
loadRegistryFromCluster) in sync on Add/Update/Delete events; if implementing a
watch is out of scope, document the staleness window in comments near
refreshRegistryPeriodically and confirm the 5-minute interval meets issue `#611`
requirements and why Bulkload remains only a startup seed.
- Around line 128-152: The buildServerK8sClient function reimplements
kubeconfig/in-cluster precedence and honors KUBECONFIG before in-cluster;
replace its manual selection with controller-runtime's ctrl.GetConfig() to use
the standard precedence. Modify buildServerK8sClient to call ctrl.GetConfig(),
handle and log any error similarly, then pass the returned *rest.Config into
client.New(..., client.Options{Scheme: scheme}) and return that client (or nil
on error) so existing uses of k8sClient and the registered v1alpha1 scheme
continue to work.

In `@pkg/validation/entitytype.go`:
- Around line 96-115: The Validate method in EntityTypeRegistry currently
appends an error for every referenced occurrence because
collectReferencedEntityTypes isn't deduplicated; update
EntityTypeRegistry.Validate to track seen normalized unknown types (e.g., using
a map[string]struct{}) before appending errors so you only add one
fmt.Errorf("unknown entityType %q", ref) per distinct normalized type; use
normalizeEntityType(ref) for dedup keys and still honor selfDefined and r.types
lookups to suppress known types.
- Around line 22-48: Bulkload currently resets r.owners to an empty map and
seeds only aggregate counts, which makes it incompatible with per-owner updates
via LoadForOwner because subsequent per-owner loads will double-count types; add
a clear doc comment on the EntityTypeRegistry.Bulkload method warning that it
does not populate owner→types mappings and should not be used if LoadForOwner or
per-owner updates will be called (recommend using BulkloadWithOwners when owners
will be tracked), referencing Bulkload, BulkloadWithOwners, LoadForOwner and
r.owners so maintainers understand the incompatibility and intended alternative.
