 | Package | Layer | Description |

-| `@singularity-ai/spectra-agent` | **Agent** | Agent loop with multi-turn tool dispatch. `defineTool()` with Zod validation, before/after hooks, parallel/sequential execution, retry with backoff, abort support. |
-| `@singularity-ai/spectra-app` | **Infrastructure** | Production runtime — `SessionEngine` (full lifecycle orchestration), `SessionManager` (CRUD + fork + audit/tree), `SessionStore` (in-memory, filesystem, SQLite, Redis), `LocalRateLimiter` + `RedisRateLimiter` (distributed sliding window), `CompositeRateLimiter` (tenant+user+provider), `CircuitBreaker`, `SseBridge` (SSE with WS-compatible interface), `HealthProbe` (K8s ready). |
