greentic-runner
Die zentrale Produktions-Runtime, die Flows hostet und ausführt, Sessions verwaltet und alle Plattformdienste koordiniert.
Greentic folgt einer geschichteten Architektur mit klarer Trennung der Zuständigkeiten:

greentic-flow
Flow-Schemadefinition, Intermediate Representation (IR), Loader und Validator für .ygtc-Dateien.
greentic-pack
Pack-Builder-CLI zum Erstellen signierter .gtpack-Archive mit Flows, Komponenten und Assets.
greentic-component
CLI zum Erstellen von Komponenten und Runtime-Hilfsprogramme zum Bauen von WASM-Komponenten.

| WASM Runtime | Wasmtime v41 | Ausführung des Component Model |
| Async Runtime | Tokio v1 | Asynchrone I/O, Task-Scheduling |
| HTTP Server | Axum v0.8 | REST-API, Webhooks |
| Message Bus | Internal event bus | Ereignisverteilung, Pub/Sub |

Tenant └── Environment (prod, staging, dev) └── Team └── Channel (messaging provider instance) └── Session (user conversation state)Die TenantCtx-Struktur fließt durch alle Operationen:
pub struct TenantCtx { pub tenant_id: String, pub env_id: String, pub team_id: Option<String>,}Greentic verwendet die Spezifikation WebAssembly Interface Types (WIT) zur Definition von Komponentenschnittstellen:
// greentic-interfaces/wit/greentic/component@0.6.0/package.witpackage greentic:component@0.6.0;
interface control { should-cancel: func() -> bool; yield-now: func();}
interface node { use greentic:types-core/core@0.6.0.{capability-id, component-id, flow-id, node-error, step-id, tenant-ctx};
record invocation-envelope { ctx: tenant-ctx, flow-id: flow-id, step-id: step-id, component-id: component-id, attempt: u32, payload-cbor: list<u8>, metadata-cbor: option<list<u8>>, }
