+# ADP — Steuerungselemente & Methoden-Vertrag v0.1 (AP2.4)
+
+**Status:** vorgeschlagen — Implementierung AP2.3g/AP2.4  
+**Stand:** 2026-07-25  
+**Bezug:** `ADP_Archetype_Method_Plugin_Architecture_v0.1.md` (AP2.3), `ADP_Archetype_and_Method_Catalog_v0.2.md`, `Kairo_Method_Design_Principles_v0.1.md`  
+**Ersetzt nicht:** AP2.3 A–F; **vertieft** Schicht 1 (Methode) und schließt Restschuld AP2.3g
+
+---
+
+## 1. Problem
+
+AP2.3 hat Archetyp (Schicht 2) und Methode (Schicht 1) technisch entkoppelt:
+
+- `GET /operating-context` liefert `ui_profile` + `data_slices`
+- `MethodDefinition` trägt `data_slices` + `compatible_archetype_keys`
+
+**Offene Lücke:** Steuerungsverhalten und Control-UI hängen noch an verstreuten Stellen:
+
+| Verhalten | Heute | Soll |
+|-----------|-------|------|
+| Kritischer Pfad | FE-Hack `METHOD_UI_FEATURES` + Archetyp-If | Methode `sequential_dependency` |
+| Product ohne Sprint | Archetyp `uiFeatures` | Methode `continuous_product` |
+| Graph-Strenge | `graph/profiles.py` separat | Methoden-Vertrag |
+| Control-Panels | Page-Ifs | Steuerungselement-Registry |
+| Methodenwahl UI | alle Methoden | nur kompatible pro Archetyp |
+
+**PO-Anforderung:** Jeder Archetyp kann mit **unterschiedlichen Steuerungsmethoden** geführt werden. Methoden bringen **eigene Steuerungselemente** mit und müssen **explizit** mit Archetypen kompatibel sein — ohne React-Ifs und ohne Duplikat-Registry.
+
+---
+
+## 2. Leitentscheidung
+
+### 2.1 Drei Registries, eine Auflösung
+
+```text
+Archetyp-Registry (Schicht 2)     → IA-Hülle, OM-Fähigkeiten, Default-Methode
+Methoden-Registry (Schicht 1)     → Motor: Strategie, Slices, Elemente, Graph
+Steuerungselement-Registry        → Katalog benannter Control-/Work-Bausteine
+
+GET /initiatives/:id/operating-context
+  → resolve(archetype, method, profile?)
+```
+
+### 2.2 Auflösungsregeln (verbindlich)
+
+| Feld | Quelle | Regel |
+|------|--------|-------|
+| `ui_profile` (Nav, Routen, Outline) | **Archetyp** | unverändert |
+| `data_slices` | **Schnittmenge** | `archetype.om_capabilities ∩ method.data_slices` |
+| `steering_elements` | **Methode** | nur aktive Methode |
+| `ui_features` | **Methode** | Verhaltensflags Work/Control |
+| `graph_profile` | **Methode** | Gate-Blocking, Fulfillment |
+| `method_capabilities` | **Methode** | Strategie, Lifecycle |
+| `compatible_methods` | **Registry** | gefiltert nach Archetyp |
+
+**Archetyp ≠ Methode:** Default-Methode ist **Empfehlung**, nicht Lock. Nutzer mit `kairo.initiative.manage` darf jede **kompatible** Methode wählen.
+
+### 2.3 Kompatibilität
+
+```text
+compatible(archetype, method) :=
+  archetype_key ∈ method.compatible_archetype_keys  (oder "*")
+  AND method.data_slices ⊆ archetype.om_capabilities
+```
+
+`om_capabilities` im Archetyp-Profil entspricht fachlich den erlaubten OM-Slices (Fallback: `dataSlices` aus `ui_profile_json`).
+
+### 2.4 Methoden-Rollen (Komposition)
+
+| Rolle | Bedeutung | Beispiel |
+|-------|-----------|----------|
+| `primary` | Einziger Motor am `steering_context.method_key` | `continuous_product` |
+| `modifier` | Ergänzt Primärmethode über Profil/Policy | `agile_iteration` (Sprint auf Product) |
+
+**MVP:** ein `method_key` pro Vorhaben; `agile_iteration` als Modifier über `method_profile_key` / `work_cycle`-Policy — kein zweiter SteeringContext.
+
+---
+
+## 3. Steuerungselemente (Schicht 1b)
+
+Ein **Steuerungselement** ist ein stabiler Key, den eine Methode aktiviert. Backend und Frontend registrieren sich darauf.
+
+| Key | Bedeutung | Typische Methode(n) |
+|-----|-----------|---------------------|
+| `next_action_primary` | Next-Action-Widget als Steuerungsdefault | alle |
+| `critical_path` | Kritischer Pfad / Execution-Graph | `sequential_dependency` |
+| `gate_fulfillment` | Gate-Fortschritt, Verify-Semantik | `program_delivery`, `product_milestone_driven`, … |
+| `work_cycle_scope` | Sprint-Zeitbox, Sprint-Backlog | `continuous_product`, `agile_iteration` |
+| `recurring_rhythm` | Rhythmen / Journey-Fokus | `maturity_progression`, `recurring_control` |
+| `queue_inbox` | Queue-Pull, Eingang prominent | `queue_pull` |
+| `maturity_stage` | Reifegrad-Stufen | `maturity_progression` |
+| `chapter_progression` | Kapitel-Fortschritt | `chapter_based_progression` |
+| `dispute_timeline` | Fristen / Verfahren | `dispute_procedure` |
+
+**Registry:** `backend/steering/elements/registry.py`  
+**Frontend:** `frontend/src/registry/steeringElementRegistry.js` — Element → Panel/Widget
+
+**Regel:** Control-/Work-Seiten composen UI aus `operating_context.steering_elements` — **keine** Archetyp-Ifs.
+
+### 3.1 UI-Features (Verhaltensflags)
+
+Zusätzlich zu Elementen (was gerendert wird) können Methoden **Verhaltensflags** setzen:
+
+| Key | Bedeutung |
+|-----|-----------|
+| `criticalPathControl` | Next-Action-Copy / Pfad-Fokus |
+| `continuousProductWorkMode` | Product-Ist ohne aktiven Sprint |
+| `steeringSnapshotOnWorkSprint` | Snapshot lazy auf Work/Sprint |
+
+Quelle: **nur Methode** (`MethodDefinition.ui_features`), nicht Archetyp.
+
+---
+
+## 4. Methoden-Vertrag (`MethodDefinition`)
+
+Erweiterung gegenüber AP2.3e:
+
+```python
+@dataclass(frozen=True)
+class MethodDefinition:
+    key: str
+    version: str

+
+---
+
+## 5. Operating Context (API-Erweiterung)
+
+`GET /api/initiatives/{id}/operating-context` liefert zusätzlich:
+
+```json
+{
+  "steering_elements": ["critical_path", "next_action_primary"],
+  "ui_features": { "criticalPathControl": true },
+  "graph_profile": {
+    "enforce_gate_blocking": true,
+    "emphasize_fulfillment": false
+  },
+  "compatible_methods": [
+    { "key": "sequential_dependency", "label": "…", "is_default": true }
+  ]
+}
+```
+
+`ui_profile.uiFeatures` am Archetyp wird **deprecated** (leer); Migration in Methoden-Registrations.
+
+---
+
+## 6. Steering API
+
+`GET /api/steering/methods?archetype_key=initiative.linear_project`
+
+- Filtert nach `method_compatible_with_archetype`
+- Response enthält `steering_elements`, `ui_features`, `compatible_archetype_keys`
+
+Methoden-Dropdown in Control zeigt nur kompatible Einträge.
+
+---
+
+## 7. Implementierungspakete
+
+| Paket | Lieferung | Abhängigkeit |
+|-------|-----------|--------------|
+| **AP2.4a** | `steering/elements/registry.py`, erweiterte `MethodDefinition`, Registrations | AP2.3e |
+| **AP2.4b** | `operating-context` + `/steering/methods` Filter | AP2.4a |
+| **AP2.4c** | FE Resolver, `steeringElementRegistry`, Pages ohne Ifs | AP2.4b |
+| **AP2.4d** | pytest + Vitest + Truth Table | AP2.4c |
+
+Optional **AP2.4e:** explizites `omCapabilities` am Archetyp-Seed (statt `dataSlices`-Missbrauch).
+
+---
+
+## 8. Erweiterungs-Workflow
+
+**Neue Methode `foo_bar`:**
+
+1. `steering/methods/registrations/foo_bar.py` — Contract vollständig
+2. Nur Keys aus `steering/elements/registry.py` referenzieren
+3. Import in `steering/__init__.py`
+4. pytest `test_method_foo_bar_contract.py`
+5. Kein Core-Edit außer Registry-Dispatcher
+
+**Neues Steuerungselement `my_panel`:**
+
+1. Eintrag in `steering/elements/registry.py`
+2. FE `steeringElementRegistry.js`
+3. Methoden, die es brauchen, tragen Key in `steering_elements`
+
+---
+
+## 9. Nicht tun
+
+- Keine Archetyp-Ifs für Control (`initiative.linear_project === …`)
+- Keine parallele Graph-Profile-Map ohne Methoden-Bezug
+- Keine Tenant-DSL für Methoden
+- Keine zweite SteeringContext-Tabelle für Komposition
+
+---
+
+## 10. Abnahme
+
+| Kriterium | Test |
+|-----------|------|
+| Operating Context liefert `steering_elements` + `ui_features` aus Methode | pytest AP2.4 |
+| Linear + `queue_pull` → keine `critical_path`, kleinere Slices | pytest AP2.3e |
+| `/steering/methods?archetype_key=…` filtert | pytest AP2.4 |
+| Control rendert Critical Path nur bei Element | Vitest + manuell |
+| Kein `METHOD_UI_FEATURES` im FE | Code-Review |
+
+---
+
+## 11. Bezug AP2.3
+
+AP2.3 A–F liefert Operating Context, Slice-Loader, Route Gating.  
+AP2.4 **schließt die methodenunabhängige Steuerungsschicht** — Voraussetzung für Archetyp-Welle 2 (B1, A3, D1) ohne Page-Patches.
