+# AP2.1 — Validation Findings Register
+## v0.1 (PO-Smoke → Architektur-Review)
+
+**Status:** aktiv — wird während AP2.1 ergänzt  
+**Stand:** 2026-07-28 (A1 Minimum Slice implementiert — PO Re-Abnahme ausstehend)  
+**Bezug:** `Sprint1_AP2_1_MVP_Validation_Report_v0.3.md`, `Kairo_MVP_Definition_v0.3.md` §5–8  
+**Dev:** https://dev.kairo.jinkendo.de · nach Deploy Migration **030** + A1-Slice
+
+---
+
+## 1. Zweck
+
+Dieses Register hält **PO-Beobachtungen aus der MVP-Validation** fest und ordnet sie architektonisch ein:
+
+| Kategorie | Bedeutung |
+|-----------|-----------|
+| **Bug** | Abweichung vom **aktuellen** Soll (Spec + gelieferte Architektur) — Fix ohne ADP |
+| **Config-Drift** | Inkonsistenz innerhalb der Plugin-/Profile-Schicht (kein Modellbruch) |
+| **Implementierungsschuld** | Architektur und Spec stimmen; Code liefert Teilmenge |
+| **Aufgeschoben (Spec)** | Explizit in Archetyp-/Methoden-Spec oder ADP als „später“ / Stufe B+ |
+| **Architektur-Lücke** | Zielmodell dokumentiert, tragfähige Basis fehlt oder widerspricht sich **über** Spec hinaus |
+
+**Leitfrage des Reviews:** Brauchen wir ein **neues Architektur-Design**, oder ist die Plugin-/Kernel-Schicht korrekt und es fehlen **Slices**?
+
+---
+
+## 2. Architektur-Urteil (Stand nach A1-Smoke)
+
+### 2.1 Kurzfazit (technisch)
+
+**Kein generelles Architektur-Design-Problem.** Die vier Schichten (Methode → Archetyp → Profil → UI-Composition, AP2.3/AP2.4) tragen den A1-Happy-Path **technisch**.
+
+### 2.1b PO-Produkturteil A1 (2026-07-28)
+
+**No-Go für echten Einsatz** — unabhängig vom grünen E2E-Test.
+
+> Leitfrage lässt sich nicht sinnvoll beantworten. Für tagesbezogenes Tracking (durchgeführt; optional Messwerte wie Anzahl, 45°-Spagat), aktive Einschätzung des Gate-Fortschritts und übersichtliche Steuerung ist der Vorhabentyp **unbrauchbar**. Hürden > Nutzen.
+
+| Dimension | Technische Validation | PO-Produktnutzen |
+|-----------|----------------------|------------------|
+| Happy Path (Anlage → Verify) | ✓ | ◐ — nur Demo, kein Alltag |
+| Leitfrage ≤2 Min (MVP §5.6) | — | **✗** |
+| Tages-Tracking / Übung erledigen | ✗ | **Blocker** |
+| Messgrößen / Metriken | ✗ | **Blocker** (PO) |
+| Gate-Fortschritt sichtbar steuerbar | ◐ | **✗** |
+| Übersichtlichkeit | ◐ | **✗** |
+
+**Architektur-Einordnung:** PO-Anforderungen stehen **bereits in SPEC A1 / Spec-D** (CadenceInstance, Tages-Übung, Kriterien, Metriken). Es fehlt nicht ein neues Design — es fehlt der **Minimal-Slice für nutzbaren A1**, der fälschlich als „post-MVP“ behandelt wurde.
+
+**Konsequenz AP2.1 / MVP Stufe A:** A1 erfüllt **nicht** die MVP-Nutzbarkeits-Bar §5 für PO-Abnahme. Gesamt-Go Stufe A **blockiert**, solange A1 Pflicht-Szenario bleibt (`Kairo_MVP_Definition_v0.3.md` §4).
+
+Die Validation zeigt drei **Lückentypen**:
+
+```text
+(1) Config-Drift     planOutlineKeys ≠ dataSlices          → schneller Fix
+(2) Spec-Deferred    CadenceInstance, Alternanz, metric    → geplant, Spec §11
+(3) Polymorphie-Gap  Kernel Q2 Work-Items: BE ja, FE nein  → Implementierungsschuld
+```

+
+---
+
+## 4. Detail-Notizen (Architektur-Check)
+
+### F-A1-01 — Eingang vs. Slices
+
+```text
+ui_profiles.py  initiative.maturity_journey:
+  planOutlineKeys: [profile, gates, inbox, work]   ← Nav zeigt Eingang
+  dataSlices:      [actions, roadmap, recurring, …]  ← kein "backlog"
+
+viewRegistry.js   /plan/inbox  requiredSlices: ['backlog']
+→ isRouteAllowedForMode = false → Redirect planDefaultRoute (/plan/gates)
+```
+
+**Urteil:** Plugin-Architektur funktioniert wie designed; **Profil-Seed ist inkonsistent**.
+
+### F-A1-02 / F-A1-06 — CadenceInstance-Schicht
+
+| Schicht | Spec | Code heute |
+|---------|------|------------|
+| RecurringElement | Container + Bindung Stufe | ✓ |
+| Cadence / Wochentage / Alternanz | Spec A1 §4.3–4.5 | ✗ |
+| CadenceInstance (eine offene Instanz) | Spec-D D4, Kernel Q2 | ✗ (nur `next_due_at` am Element) |
+| Erfüllung → nächste Instanz | Spec A1 Happy Path §9.3 | ◐ (manuell / overdue-Logik minimal) |
+
+**Urteil:** **Kein falsches Design** — Normalization-Programm beschreibt Ziel; MVP lieferte **Minimal-Rhythmus**. Spec A1 §11 listet das explizit als Lücke.
+
+### F-A1-03 — Work-Item-Polymorphie (Kernel Q2)
+
+| Work Item | Next Action BE | Next Action FE Link |
+|-----------|----------------|---------------------|
+| Action | ✓ | ✓ |
+| Backlog | ✓ | ✓ |
+| Recurring / Cadence | ✓ (`recurring_due`) | ✗ (nur Text `recommended_action`) |
+
+**Urteil:** **Architektur-Lücke nur in der Präsentationsschicht** — Steering-Kernel und Strategies sind erweiterbar; FE muss polymorphe Ziele unterstützen (Link-Typ-Registry analog Backend `kind`).
+
+### F-A1-04 / F-A1-05 — Kriterien & Metriken
+
+- **Evidence → satisfied:** beabsichtigt (`roadmap_criteria.prepare_criteria_for_verify`).
+- **Manuelle Kriterien:** bleiben offen bis manuell / waived — korrekt.
+- **Metriken:** Schema vorbereitet, **keine** Regel-Engine — ADP „später“.
+
+**Urteil:** Gate-Modell ist **generisch genug**; fehlende Metrik-Auswertung ist **Feature-Deferral**, kein Redesign.
+
+### F-A1-07 — Activity Set bei Stufenwechsel
+
+`maturity_stage_transition.on_maturity_stage_reached`:
+
+- pausiert aktive Recurring ✓  
+- aktiviert nächste Stufe ✓  
+- legt neue Recurring-Übung an ✓  
+- **keine** Stage-Actions, **keine** Graph-Aktivierung weiterer Plan-APs  
+
+Spec A1 §4.4 verlangt volles Set — **Implementierungsschuld**, Scope AP2.0e war Minimal-Slice.
+
+---
+
+## 5. Abgleich mit SPEC_A1 §11 (Ist-Stand-Tabelle)
+
+| Spec §11 Zeile | Validation bestätigt |
+|----------------|-------------------|
+| Multi-Übung / Alternanz fehlt | F-A1-02 ✓ |
+| Stage Activity Set Teilmenge | F-A1-07 ✓ |
+| UI Stufe-Detail lückenhaft | F-A1-02, F-A1-03 ✓ |
+| steering_elements FE/BE Parität | F-A1-03 (recurring in Kontrolle ✓, Work ◐) |
+
+**Keine neue Spec-Zeile nötig** — Register präzisiert PO-Sicht für AP2.1.
+
+**Urteil:** **Kein falsches Design** — PO-Anforderung = Spec §4 / Spec-D. MVP lieferte **Infrastruktur ohne Ist-Schicht**. Für PO-Abnahme ist das **kein „später“**, sondern **fehlender A1-Kern**.
+
+### F-A1-09 / F-A1-10 — PO-Leitfrage & Unübersichtlichkeit
+
+**PO (2026-07-28, wörtlich zusammengefasst):**
+
+- Leitfrage nicht sinnvoll beantwortbar  
+- Tages-Tracking + optional Messwerte (Anzahl, Grad, …) + aktive Gate-Einschätzung **erforderlich** für echten Einsatz  
+- Extreme Unübersichtlichkeit → **Hürden größer als Nutzen**
+
+**Architektur:** Symptome von fehlendem CadenceInstance-Modell, Work-UI auf AP statt Übung, IA-Rauschen (Eingang, Journey). **Kein Widerspruch** zwischen Vision und Spec — **Widerspruch zwischen geliefertem MVP-Slice und PO-Mindestnutzen**.
+
+---
+
+## 6. Priorisierte Follow-ups (PO-gesteuert)
+
+### 6.1 A1 Minimum Usability Slice (vor erneuter A1-Abnahme)
+
+**Implementiert (2026-07-28, uncommitted):** Migration 030, `cadence_instance` + `POST /api/recurring/{id}/complete`, `WorkTodayPracticePanel`, Next-Action-Link `#today-practice`, Gate-Fortschritt in `MaturityStagePanel`, Eingang aus A1-Nav. **Offen:** PO Re-Abnahme; Metric-Kriterium manuell (Slice #5, optional vor Re-Test).
+
+| # | Lieferung | Decke PO-Schmerz | Status |
+|---|-----------|------------------|--------|
+| 1 | **CadenceInstance + „Heute erledigt“** | Tages-Tracking | ✓ implementiert |
+| 2 | **Ausführen/Today = Übung** | Nutzen Alltag | ✓ implementiert |
+| 3 | **Kontrolle: Gate-Fortschritt** | Gate-Einschätzung | ✓ implementiert (Kriterien offen/erfüllt) |
+| 4 | **IA A1** (Eingang weg) | Unübersichtlichkeit | ✓ implementiert |
+| 5 | **Metric-Kriterium manuell** | Messgrößen | ◐ Messnotiz am Complete; Auto-Engine weiter offen |
+
+Alternanz, volle Metric-Engine, Activity-Set-Automation → **nach** Slice 1–4.
+
+### 6.2 Technische Quick-Wins (P0)
+
+| Prio | ID | Slice |
+|------|-----|-------|
+| P0 | F-A1-01 | Eingang aus A1-Nav |
+| P1 | F-A1-03 | Next Action → Recurring/Übung-Aktion |
+
+---
+
+## 7. Konsequenz für AP2.1 / MVP Stufe A
+
+| Option | Bedeutung |
+|--------|-----------|
+| **A — A1 nachziehen** | Validation pausieren; **A1 Minimum Slice** (§6.1) liefern; A1 erneut smoke-testen |
+| **B — MVP-Definition anpassen** | A1 vorübergehend aus Stufe-A-Abnahfe (PO-Entscheidung + Doku) — **nur wenn A2+B2b als MVP reichen** |
+| **C — Gesamt No-Go** | AP2.1 stoppt bei Stufe A bis A1 oder Scope-Entscheidung |
+
+**Empfehlung:** **Option A** — Architektur trägt; Spec war richtig; Implementierung war zu dünn. A2/B2b-Smoke **parallel** möglich, Gesamt-Go aber nicht ohne A1-Lösung (Option A oder explizite B).

+| 1 | **`cadence_instances`** + API `complete` | F-A1-02, F-A1-06 | Eine offene Instanz pro aktivem Recurring; „Heute erledigt“ → nächste Fälligkeit |
+| 2 | **`WorkTodayPracticePanel`** | F-A1-03 | Ausführen/Today zeigt Übung zuerst; optional Messnotiz |
+| 3 | **Next Action → Übung** | F-A1-03 | Klickbarer Pfad zu Today-Übung |
+| 4 | **Gate-Fortschritt** am aktiven Stufe-Panel | F-A1-04 | Kriterien offen/erfüllt sichtbar + Link Gate-Detail |
+| 5 | **IA A1** | F-A1-01, F-A1-10 | Eingang aus Nav; Plan-Outline nur profile + gates + work |

+```text
+A1.1  Migration 030 + cadence_instance service + complete API + pytest
+A1.2  WorkTodayPracticePanel + Composition + NextAction-Link
+A1.3  MaturityStagePanel Gate-Fortschritt + ui_profile IA
+A1.4  Re-Validation A1 (PO) → Report §3 Go/Bedingt
+```
+
+---
+
+## 5. Re-Abnahme-Kriterien (PO)
+
+1. PO kann **heute** Übung als erledigt markieren (+ optional Messnotiz).  
+2. **Leitfrage ≤2 Min:** „Welche Übung heute?“ — ohne AP-Detour.  
+3. **Kontrolle:** aktive Stufe + Kriterien-Fortschritt erkennbar.  
+4. Kein Eingang-Redirect / Nav-Rauschen.
+
+---
+
+*Nach Abschluss: Findings Register F-A1-* auf erledigt setzen; AP2.1 A1 erneut smoke-testen.*
