## PRD Analysis

### Functional Requirements

- FR1: Inscription autonome d'un nouvel utilisateur.
- FR2: Authentification sécurisée (Session/JWT).
- FR3: Isolation stricte des données (Flux, Lectures, Favoris) par compte utilisateur.
- FR4: Ajout de flux via URL (support RSS/Atom auto-détecté).
- FR5: Détection automatique des métadonnées (Titre, Icône) à l'ajout.
- FR6: Importation de flux en masse via fichier OPML.
- FR7: Gestion des flux (Renommer, Supprimer).
- FR8: Dashboard unifié "Nouveautés" trié par date.
- FR9: Mode "Lecture Plaisir" avec extraction du contenu principal (nettoyage HTML).
- FR10: Marquage "Lu" manuel ou automatique (scroll/swipe).
- FR11: Marquage "Tout lu" par flux ou global.
- FR12: Gestion des Favoris ("Star" / "Read Later").
- FR13: Push temps réel des nouveaux articles (Websockets) vers le client connecté.
- FR14: Synchronisation instantanée de l'état de lecture entre appareils.
- FR15: Liste des utilisateurs inscrits (Vue Admin).
- FR16: Suppression de compte utilisateur.

**Total FRs:** 16

### Non-Functional Requirements

- NFR1: Empreinte mémoire totale (Back+Front) < 150 Mo RAM.
- NFR2: Temps de chargement article (TTI) < 100ms perçu.
- NFR3: Score Lighthouse Mobile > 90.
- NFR4: Architecture SPA (Single Page App) optimisée "Offline First" (Optimistic UI).
- NFR5: Redémarrage conteneur (Recovery Time) < 5 secondes.
- NFR6: Résilience totale aux flux défaillants (Timeout 5s strict, pas de blocage global).
- NFR7: Isolation des données inter-utilisateurs validée par tests.
- NFR8: Aucune télémétrie ou fuite de données (Privacy by Design).

**Total NFRs:** 8

### Additional Requirements

- **Technical Stack:** Frontend SPA, Backend (Go/Rust/Node), DB SQLite, Single Docker Image.
- **Deployment:** `docker-compose up` simplicity.

### PRD Completeness Assessment

The PRD is highly focused and structured. It contains clear, testable Functional and Non-Functional requirements.
- **Strengths:** Clear separation of concerns, measurable NFRs, specific user journeys.
- **Gaps:** No specific API contract defined (deliberate for Architecture phase), no specific UI wireframes (deliberate for UX phase).
- **Verdict:** PRD is **Implementation Ready** from a requirements perspective, pending Architecture and UX decisions.

### Missing Requirements

**ALL Functional Requirements are currently uncovered.**
No "Epics & Stories" document was found. This is expected as the project is in the initial PRD phase.

### Coverage Statistics

- Total PRD FRs: 16
- FRs covered in epics: 0
- Coverage percentage: **0%**

## UX Alignment Assessment

### UX Document Status

**NOT FOUND**

### Alignment Issues

- **Implied UI Requirement:** PRD mandates "Mobile First" and "Lecture Plaisir" experience.
- **Missing Artifact:** No UX design document (Wireframes/Mockups) exists to guide frontend implementation.
- **Risk:** Developing "Lecture Plaisir" view without design validation risks "Engineered UI" (functional but ugly) which violates Success Criteria ("Adoption personnelle").

### Warnings

⚠️ **WARNING:** UX is implied but missing. Proceeding to implementation without a UX phase is high risk for the "User Success" criteria.

## Epic Quality Review

### Status: SKIPPED

**Reason:** No Epics & Stories document found to review.

## Summary and Recommendations

### Overall Readiness Status

🟡 **PARTIALLY READY** (Requirements Clear, but Architecture & Design Missing)

### Critical Issues Requiring Immediate Action

1. **Missing Technical Architecture:** The PRD lists constraints (150MB RAM, Docker), but does not define *how* to achieve them (Go vs Rust? React vs Vue? DB Schema?).
2. **Missing Visual Design:** "Lecture Plaisir" is a subjective success criteria. Attempting to code this without a visual reference is risky.
3. **Missing Planning (Epics):** No work breakdown structure exists yet.

### Recommended Next Steps

1. **Create Architecture:** Use the **Architect Agent** (`/architect`) to define the stack that meets the NFRs (ex: Go + SQLite + Preact?).
2. **Create UX Design:** Use the **UX Agent** (`/ux-designer`) to sketch the "Lecture Plaisir" view.
3. **Create Epics:** Once stack and design are clear, break down the work.

### Final Note

The PRD itself is high quality and provides a solid foundation. The "Red Indicators" (Missing Epics/Arch) are normal for this stage. **Do not start coding yet.** The project needs an architectural blueprint first.
