 ## Conclusion
 
 Ces consignes constituent un cadre de production strict. Elles imposent une analyse préalable via un arbre des fichiers, un typage TypeScript sans contournement, une non-duplication systématique, une architecture fondée sur des abstractions pertinentes, l’usage raisonné de patterns, une journalisation exhaustive des erreurs et un refus explicite des fallbacks implicites. Appliquées rigoureusement, elles conduisent à un code TypeScript robuste, évolutif et cohérent avec un référentiel de qualité de haut niveau.

+# Contributing to zapwall4science
+
+## Principles
+- No fallbacks or silent failures.
+- No analytics; no tests added unless explicitly requested.
+- Respect lint, type-check, accessibility and exactOptionalPropertyTypes.
+- No `ts-ignore`, no untyped `any`, no console logs if a logger exists.
+
+## Setup
+- Node 18+, npm
+- `npm install`
+- `npm run lint`
+- `npm run type-check`
+
+## Coding guidelines
+- Split large components/functions to stay within lint limits (max-lines, max-lines-per-function).
+- Prefer typed helpers/hooks; avoid duplication.
+- Errors must surface with clear messages; do not swallow exceptions.
+- Storage: IndexedDB encrypted (AES-GCM) via `lib/storage/cryptoHelpers.ts`; use provided helpers.
+- Nostr: use `lib/articleMutations.ts` and `lib/nostr*.ts` helpers; no direct fallbacks.
+
+## Workflow
+- Branch from main; keep commits focused.
+- Run lint + type-check before PR.
+- Document fixes in `fixKnowledge/` and features in `features/`.
+
+## Accessibility
+- Respect ARIA, keyboard, contrast requirements; no regressions.
+
+## What not to do
+- No analytics, no ad-hoc tests, no environment overrides, no silent retry/fallback.

+Permettre aux auteurs d’éditer ou supprimer leurs articles en publiant des événements Nostr dédiés (update + delete), avec confirmation explicite côté UI.
+
+**Impacts**
+- Parcours auteur : édition depuis la liste de mes articles, suppression confirmée avant envoi de l’événement kind 5.
+- Stockage local : contenu privé ré-encrypté et ré-enregistré pour les mises à jour.
+- Pas d’impact côté lecteurs (pas de fallback).
+
+**Modifications**
+- `lib/articleMutations.ts` : publication update/delete (tags e, replace), réutilisation du stockage chiffré.
+- `components/UserArticles.tsx`, `components/UserArticlesList.tsx`, `components/UserArticlesEditPanel.tsx` : UI édition/suppression avec confirmation, découpage pour respecter lint/max-lines.
+- `lib/articleInvoice.ts` : factorisation des tags de preview.
+
+**Modalités de déploiement**
+Standard front : build Next.js habituel. Pas de migrations ni dépendances supplémentaires.
+
+**Modalités d’analyse**
+- Vérifier qu’un auteur connecté peut éditer puis voir son article mis à jour dans la liste.
+- Vérifier que la suppression publie l’événement et retire l’article de la liste locale.
+- Sur erreur de publication, message d’erreur affiché (aucun fallback silencieux).

+# Notifications scope (Dec 2025)
+
+**Decision:** Do not implement notifications for mentions, reposts, or likes. Only payment notifications remain active. If comment notifications are later requested, they must be explicitly approved.
+
+**Impacts:**
+- No parsing/subscription for mention/repost/like events.
+- UI does not surface badges or panels for these types.
+- Avoids extra relay traffic and parsing logic.
+
+**Constraints/quality:**
+- No fallbacks.
+- No analytics.
+- Keep error logging structured if new notification types are ever added.

+# Séries, média NIP-95 et événements Nostr (spec v1, Jan 2026)
+
+## 1) Événements et tags (rien en local)
+
+Namespace tag communs (tous les events) :
+- `site`: `zapwall4science`
+- `category`: `science-fiction` | `scientific-research`
+- `author`: pubkey auteur
+- `series`: id série (event id de la série)
+- `article`: id article (event id de l’article)
+
+Kinds proposés (réutilisation kind 1 pour compat) :
+- Série : kind `1` avec tag `kind_type: series`
+  - tags : `site`, `category`, `author`, `series` (self id), `title`, `description`, `cover` (URL NIP-95), `preview`
+- Article : kind `1` avec tag `kind_type: article`
+  - tags : `site`, `category`, `author`, `series`, `article` (self id), `title`, `preview`, `banner` (URL NIP-95), `media` (0..n URLs NIP-95)
+  - contenu markdown public (preview) ; privé chiffré inchangé côté storage
+- Avis (critique) : kind `1` avec tag `kind_type: review`
+  - tags : `site`, `category`, `author`, `series`, `article`, `reviewer` (pubkey), `title`, `created_at`
+  - contenu = avis en clair
+- Achat article (zap receipt) : kind `9735` (zap) avec tags standard `p`, `e`, plus `site`, `category`, `author`, `series`, `article`, `kind_type: purchase`
+  - amount = millisats, hors frais site gérés off-chain
+- Paiement remerciement avis : kind `9735` zap avec `kind_type: review_tip`, tags `site`, `category`, `author`, `series`, `article`, `reviewer`, `review_id`
+- Paiement sponsoring : kind `9735` zap avec `kind_type: sponsoring`, tags `site`, `category`, `author`, `series` (optionnel), `article` (présentation si ciblé)
+
+Notes :
+- Tous les cumuls (sponsoring, paiements article, remerciements avis) calculés via zap receipts filtrés par `kind_type`.
+- Séries sans sponsoring autorisées (0).
+
+## 2) Média NIP-95 (images/vidéos)
+
+- Upload via NIP-95 (encrypted file events). Contraintes :
+  - Images/photos : max 5 Mo, png/jpg/jpeg/webp.
+  - Vidéos : max 45 Mo.
+- Stockage chiffré (même logique qu’articles) ; URL NIP-95 insérée dans markdown et bannière.
+- Validation côté client : type MIME, taille, échec → erreur surfacée (pas de fallback).
+
+## 3) Pages / navigation
+
+Hiérarchie : site → catégorie (SF/Recherche) → auteurs → auteur → série → articles → article.
+
+- Page auteur : liste des séries (cover type “livre”, titre, desc, preview, cumul sponsoring/paiements agrégés via zap receipts). Profil Nostr affiché.
+- Page série : détails série (cover, desc, preview), cumul sponsoring série + paiements articles de la série, liste d’articles de la série.
+- Article : preview public, contenu privé chiffré inchangé, bannière NIP-95, média insérés dans markdown.

+
+## 5) Wording “critiques”
+
+- Affichage des avis en tant que “critiques”.
+- Liste des critiques : afficher contenu + auteur (pubkey→profil) ; pas de liste distincte “critiques” séparée des avis (juste les avis).
+
+## 6) TODO d’implémentation (proposé)
+
+- Types : étendre `types/nostr.ts` avec Series, Review, media refs; enum `KindType`.
+- Upload NIP-95 : service dédié (validation taille/type, retour URL).
+- Publisher : ajouter création série (event), article avec tags série/media/banner.
+- Parsing : `nostrEventParsing` pour séries/articles/avis avec tags `kind_type`.
+- Aggregation : service zap pour cumuls (sponsoring/purchase/review_tip) par auteur/série.
+- UI :
+  - Form auteur/série/article (cover/banner, sélection série, markdown+preview, upload media).
+  - Pages auteur/série avec stats cumulées.
+- Pas de stockage local pour méta (tout via events).

+# Storage encryption (IndexedDB) – Dec 2025
+
+**Scope**
+- Encrypt private article content and invoices stored in IndexedDB using Web Crypto (AES-GCM).
+- Deterministic per-article secret derived from a persisted master key.
+- No fallbacks; fails if IndexedDB or Web Crypto is unavailable.
+
+**Key management**
+- Master key generated once in browser (`article_storage_master_key`, random 32 bytes, base64) and kept in localStorage.
+- Per-article secret: `<masterKey>:<articleId>` (used only client-side).
+
+**Implementation**
+- `lib/storage/cryptoHelpers.ts`: AES-GCM helpers (base64 encode/decode, encrypt/decrypt).
+- `lib/storage/indexedDB.ts`: store/get now require a secret; payloads encrypted; unchanged API surface via `storageService`.
+- `lib/articleStorage.ts`: derives per-article secret, encrypts content+invoice on write, decrypts on read, same expiration (30 days).
+
+**Behavior**
+- If IndexedDB or crypto is unavailable, operations throw (no silent fallback).
+- Existing data written before encryption won’t decrypt; new writes are encrypted.
+
+**Next steps (optional)**
+- Rotate master key with migration plan.
+- Add per-user secrets or hardware-bound keys if required.

+# Lint & type fixes (exactOptionalPropertyTypes)
+
+**Problem:** TypeScript strict optional props and nostr-tools API differences caused `npm run type-check` and `next lint` to fail.
+
+**Impact:** Build blocked (exact optional props errors, nostr-tools signing types), lint blocked (`max-lines-per-function`, `prefer-const`).
+
+**Root cause:** Code was written against older nostr-tools typings and passed `undefined` into optional props under `exactOptionalPropertyTypes`.
+
+**Corrections (code):**
+- Normalized optional props handling (conditional spreads) across editor, fields, notifications, storage, markdown rendering.
+- Added safe category handling for article drafts; tightened defaults and guards.
+- Aligned signing with nostr-tools 1.17.0 (explicit `pubkey`/`created_at`, hash/sign helpers).
+- Fixed async return contracts, removed unused params, and satisfied lint structure rules.
+- Kept storage and notification payloads free of `undefined` fields; guarded link rendering.
+
+**Modifications (files):** `components/ArticleEditor*.tsx`, `components/ArticleField.tsx`, `components/UserArticles.tsx`, `components/CategorySelect.tsx`, `lib/{nostr,nostrRemoteSigner,nostrconnect,articlePublisher,articleStorage,markdownRenderer,notifications,zapVerification}.ts`, `hooks/useArticles.ts`, `hooks/useUserArticles.ts`, `types/nostr-tools-extended.ts`, `package.json` (nostr-tools 1.17.0).
+
+**Deployment:** No special steps; run `npm run lint && npm run type-check` (already clean).
+
+**Analysis:** Ensured strict optional handling without fallbacks, restored compatibility with stable nostr-tools API, and kept functions within lint boundaries.

+## Problème
+Erreurs TypeScript `exactOptionalPropertyTypes` et avertissements ESLint `max-lines-per-function` sur les composants de sélection de séries (ArticleEditorForm, Profile, UserArticles).
+
+## Impacts
+- Blocage du `tsc --noEmit` et du lint, empêchant le déploiement.
+- Risque de régressions UI (sélection de série) si les props optionnelles sont mal typées.
+
+## Cause
+Propagation de props optionnelles (`seriesOptions`, `onSelectSeries`, `selectedSeriesId`) sans inclure explicitement `undefined` dans les signatures avec `exactOptionalPropertyTypes: true`.
+
+## Root cause
+Contrats de composants non alignés sur les exigences strictes TypeScript (exactOptionalPropertyTypes) et fonctions trop longues (>40 lignes) dans ArticleEditorForm et UserArticles.
+
+## Corrections
+- Typage explicite des props optionnelles avec `| undefined` et propagation conditionnelle des props.
+- Refactoring des fonctions longues : extraction des handlers (SeriesSelect) et découpage de `createLayoutProps`.
+
+## Modifications
+- `components/ArticleEditor.tsx`, `components/ArticleEditorForm.tsx`, `components/ProfileArticlesSection.tsx`, `components/ProfileSeriesBlock.tsx`, `components/SeriesSection.tsx`, `components/SeriesList.tsx`, `components/SeriesCard.tsx`, `components/UserArticles.tsx`, `components/UserArticlesList.tsx`, `components/ProfileView.tsx`.
+- Ajustements de typage et réduction des fonctions >40 lignes.
+
+## Modalités de déploiement
+Pas d’action spécifique : lint et type-check passent (`npm run lint`, `npm run type-check`). Déployer via la pipeline habituelle.
+
+## Modalités d'analyse
+- Vérifier `npm run lint` et `npm run type-check`.
+- Tester la sélection/filtrage de série dans l’éditeur d’articles et sur la page profil (navigation série).
