Kubernetes-Native Architecture +**Status**: MANDATORY +**Applies To**: All components (Backend, Operator, Runner orchestration) + All features MUST be built using Kubernetes primitives and patterns: -- Custom Resource Definitions (CRDs) for domain objects (AgenticSession, ProjectSettings, RFEWorkflow) -- Operators for reconciliation loops and lifecycle management -- Jobs for execution workloads with proper resource limits -- ConfigMaps and Secrets for configuration management -- Services and Routes for network exposure -- RBAC for authorization boundaries +- **Custom Resource Definitions (CRDs)** for domain objects + - `AgenticSession` - AI execution sessions + - `ProjectSettings` - Multi-tenant project configuration + - `RFEWorkflow` - Request for Enhancement workflows -**Rationale**: Kubernetes-native design ensures portability, scalability, and enterprise-grade operational tooling. Violations create operational complexity and reduce platform value. +- **Operators** for reconciliation loops and lifecycle management + - Watch for CR changes + - Reconcile to desired state + - Handle edge cases and failure scenarios -### II. Security & Multi-Tenancy First +- **Jobs** for execution workloads + - Proper resource limits (CPU, memory) + - Timeout configuration + - Failure policies and retry logic + +- **ConfigMaps and Secrets** for configuration management + - Secrets for sensitive data (API keys, tokens) + - ConfigMaps for non-sensitive configuration + - Project-scoped isolation -Security and isolation MUST be embedded in every component: +- **Services and Routes** for network exposure + - Internal ClusterIP for inter-component communication + - NodePort/LoadBalancer/Ingress for external access + - TLS termination at appropriate layers -- **Authentication**: All user-facing endpoints MUST use user tokens via `GetK8sClientsForRequest()` -- **Authorization**: RBAC checks MUST be performed before resource access -- **Token Security**: NEVER log tokens, API keys, or sensitive headers; use redaction in logs -- **Multi-Tenancy**: Project-scoped namespaces with strict isolation -- **Principle of Least Privilege**: Service accounts with minimal permissions -- **Container Security**: SecurityContext with `AllowPrivilegeEscalation: false`, drop all capabilities -- **No Fallback**: Backend service account ONLY for CR writes and token minting, never as fallback +- **RBAC** for authorization boundaries + - Namespace-scoped roles for multi-tenancy + - ClusterRoles only when truly cluster-wide access needed + - Service accounts with minimal permissions -**Rationale**: Security breaches and privilege escalation destroy trust. Multi-tenant isolation is non-negotiable for enterprise deployment. +**Rationale**: Kubernetes-native design ensures portability, scalability, and enterprise-grade operational tooling. Violations create operational complexity, reduce platform value, and prevent leveraging Kubernetes ecosystem tools. -### III. Type Safety & Error Handling (NON-NEGOTIABLE) +**Violation Consequences**: Features built outside Kubernetes patterns create: +- Operational silos requiring custom tooling +- Scaling limitations +- Security gaps in multi-tenant isolation +- Incompatibility with enterprise deployment requirements + +--- + +### II. Security & Multi-Tenancy First + +**Status**: NON-NEGOTIABLE +**Applies To**: All components with user-facing endpoints or resource access + +Security and isolation MUST be embedded in every component from initial design: + +#### Authentication +- All user-facing endpoints MUST use user tokens via `GetK8sClientsForRequest()` +- No unauthenticated endpoints except health checks and metrics +- Token validation on every request +- Session management following security best practices + +#### Authorization +- RBAC checks MUST be performed before resource access +- Project-scoped authorization enforced at API layer +- Validate user permissions before Kubernetes client operations +- Deny by default - explicit grants required + +#### Token Security +- NEVER log tokens, API keys, or sensitive headers +- Use redaction in logs (e.g., `token=****`) +- Secrets stored in Kubernetes Secrets with appropriate RBAC +- Rotate tokens regularly (document rotation procedures) + +#### Multi-Tenancy +- Project-scoped namespaces with strict isolation +- Network policies preventing cross-project access +- Resource quotas per project/namespace +- Separate service accounts per project + +#### Principle of Least Privilege +- Service accounts with minimal permissions +- No cluster-admin except for installation +- Namespace-admin only for project owners +- Read-only access by default + +#### Container Security +- SecurityContext with `AllowPrivilegeEscalation: false` +- Drop all capabilities, add only required ones +- Run as non-root user (UID > 1000) +- Read-only root filesystem where possible + +#### Backend Service Account Usage +- Backend service account ONLY for: + - CR writes to Kubernetes + - Token minting for temporary access +- NEVER use as fallback for failed user authentication +- Never use for user resource access + +**Rationale**: Security breaches and privilege escalation destroy trust and platform viability.

Resource Lifecycle Management -Kubernetes resources MUST have proper lifecycle management: +**Status**: MANDATORY +**Applies To**: All Kubernetes resource creation and deletion + +Kubernetes resources MUST have proper lifecycle management to prevent resource leaks: + +#### OwnerReferences (ALWAYS Required) + +- ALWAYS set on child resources (Jobs, Secrets, PVCs, Services, ConfigMaps) +- Use `Controller: true` for primary owner +- Enables automatic cascading deletion +- Prevents orphaned resources + +```go +// Example: Set owner reference +ownerRef := metav1.OwnerReference{ + APIVersion: session.APIVersion, + Kind: session.Kind, + Name: session.Name, + UID: session.UID, + Controller: ptr.To(true), + BlockOwnerDeletion: ptr.To(false), // Important for multi-tenant +} +job.OwnerReferences = []metav1.OwnerReference{ownerRef} +``` + +#### BlockOwnerDeletion (Do NOT Use) + +- **Never set `BlockOwnerDeletion: true`** +- Causes permission issues in multi-tenant environments +- Prevents cascading deletion when expected +- Users without delete permissions on children cannot delete parent + +#### Idempotency + +- Resource creation MUST check existence first +- Handle `AlreadyExists` errors gracefully +- Compare existing resource with desired state +- Update if necessary, no-op if already correct + +```go +// Example: Idempotent create +secret, err := clientset.CoreV1().Secrets(namespace).Get(ctx, name, metav1.GetOptions{}) +if apierrors.IsNotFound(err) { + // Create new secret + secret, err = clientset.CoreV1().Secrets(namespace).Create(ctx, newSecret, metav1.CreateOptions{}) +} else if err != nil { + return fmt.Errorf("failed to get secret: %w", err) +} +// Secret exists, optionally update if needed +``` + +#### Cleanup on Deletion + +- Rely on OwnerReferences for automatic cascading deletes +- Use finalizers ONLY when external cleanup required +- Remove finalizers after cleanup completes +- Handle finalizer failures gracefully + +#### Goroutine Safety + +- Exit monitoring goroutines when parent resource deleted +- Use context cancellation for graceful shutdown +- Prevent goroutine leaks on resource deletion + +```go +// Example: Context-aware goroutine +go func(ctx context.Context) { + for { + select { + case <-ctx.Done(): + log.Info("stopping monitor", "reason", ctx.Err()) + return + case <-ticker.C: + // Do monitoring work + } + } +}(ctx) +``` + +**Rationale**: Resource leaks waste cluster capacity, cause quota exhaustion, and eventually lead to outages. Proper lifecycle management ensures automatic cleanup and prevents orphaned resources that accumulate over time. -- **OwnerReferences**: ALWAYS set on child resources (Jobs, Secrets, PVCs, Services) -- **Controller References**: Use `Controller: true` for primary owner -- **No BlockOwnerDeletion**: Causes permission issues in multi-tenant environments -- **Idempotency**: Resource creation MUST check existence first -- **Cleanup**: Rely on OwnerReferences for cascading deletes -- **Goroutine Safety**: Exit monitoring goroutines when parent resource deleted +**Violation Consequences**: +- Orphaned resources accumulate indefinitely +- Quota exhaustion prevents new resources +- Manual cleanup required (toil) +- Production outages from resource exhaustion +- Storage leaks from abandoned PVCs -**Rationale**: Resource leaks waste cluster capacity and cause outages.
