 name: find-skills
 description: Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

 # Find Skills
 This skill helps you discover and install skills from the open agent skills ecosystem.
 ## When to Use This Skill
 Use this skill when the user:
 - Asks "how do I do X" where X might be a common task with an existing skill
 - Says "find a skill for X" or "is there a skill for X"
 - Asks "can you do X" where X is a specialized capability
 - Expresses interest in extending agent capabilities
 - Wants to search for tools, templates, or workflows
 - Mentions they wish they had help with a specific domain (design, testing, deployment, etc.)
 ## What is the Skills CLI?
 The Skills CLI (`npx skills`) is the package manager for the open agent skills ecosystem. Skills are modular packages that extend agent capabilities with specialized knowledge, workflows, and tools.
 **Key commands:**
 - `npx skills find [query] [--owner <owner>]` - Search for skills interactively or by keyword, optionally scoped to a GitHub owner
 - `npx skills add <package>` - Install a skill from GitHub or other sources
 - `npx skills check` - Check for skill updates
 - `npx skills update` - Update all installed skills
 **Browse skills at:** https://skills.sh/
 ## How to Help Users Find Skills
 ### Step 1: Understand What They Need
 When a user asks for help with something, identify:
 1. The domain (e.g., React, testing, design, deployment)
 2. The specific task (e.g., writing tests, creating animations, reviewing PRs)
 3. Whether this is a common enough task that a skill likely exists
 ### Step 2: Check the Leaderboard First
 Before running a CLI search, check the [skills.sh leaderboard](https://skills.sh/) to see if a well-known skill already exists for the domain. The leaderboard ranks skills by total installs, surfacing the most popular and battle-tested options.
 For example, top skills for web development include:
 - `vercel-labs/agent-skills` — React, Next.js, web design (100K+ installs each)
 - `anthropics/skills` — Frontend design, document processing (100K+ installs)
 ### Step 3: Search for Skills
 If the leaderboard doesn't cover the user's need, run the find command:
 ```bash
 npx skills find [query] [--owner <owner>]
 ```
 For example:
 - User asks "how do I make my React app faster?" → `npx skills find react performance`
 - User asks "can you help me with PR reviews?" → `npx skills find pr review`
 - User asks "I need to create a changelog" → `npx skills find changelog`
 ### Step 4: Verify Quality Before Recommending
 **Do not recommend a skill based solely on search results.** Always verify:
 1. **Install count** — Prefer skills with 1K+ installs. Be cautious with anything under 100.
 2. **Source reputation** — Official sources (`vercel-labs`, `anthropics`, `microsoft`) are more trustworthy than unknown authors.
 3. **GitHub stars** — Check the source repository. A skill from a repo with <100 stars should be treated with skepticism.
 ### Step 5: Present Options to the User
 When you find relevant skills, present them to the user with:
 1. The skill name and what it does
 2. The install count and source
 3. The install command they can run
 4. A link to learn more at skills.sh
 Example response:
 ```
 I found a skill that might help! The "react-best-practices" skill provides
 React and Next.js performance optimization guidelines from Vercel Engineering.
 (185K installs)
 To install it:
 npx skills add vercel-labs/agent-skills@react-best-practices
 Learn more: https://skills.sh/vercel-labs/agent-skills/react-best-practices
 ```
 ### Step 6: Offer to Install
 If the user wants to proceed, you can install the skill for them:
 ```bash
 npx skills add <owner/repo@skill> -g -y
 ```
 The `-g` flag installs globally (user-level) and `-y` skips confirmation prompts.
 ## Common Skill Categories
 When searching, consider these common categories:
 | Category        | Example Queries                          |
 | --------------- | ---------------------------------------- |
 | Web Development | react, nextjs, typescript, css, tailwind |
 | Testing         | testing, jest, playwright, e2e           |
 | DevOps          | deploy, docker, kubernetes, ci-cd        |
 | Documentation   | docs, readme, changelog, api-docs        |
 | Code Quality    | review, lint, refactor, best-practices   |
 | Design          | ui, ux, design-system, accessibility     |
 | Productivity    | workflow, automation, git                |
 ## Tips for Effective Searches
 1. **Use specific keywords**: "react testing" is better than just "testing"
 2. **Try alternative terms**: If "deploy" doesn't work, try "deployment" or "ci-cd"
 3. **Check popular sources**: Many skills come from `vercel-labs/agent-skills` or `ComposioHQ/awesome-claude-skills`
 ## When No Skills Are Found
 If no relevant skills exist:
 1. Acknowledge that no existing skill was found
 2. Offer to help with the task directly using your general capabilities
 3. Suggest the user could create their own skill with `npx skills init`
 Example:
 ```
 I searched for skills related to "xyz" but didn't find any matches.
 I can still help you with this task directly! Would you like me to proceed?
 If this is something you do often, you could create your own skill:
 npx skills init my-xyz-skill

 ## Learned User Preferences
 - Préfère les échanges en français, avec des explications détaillées et claires (éviter le jargon flou).
- Interface : tout libellé via i18n dans les 15 fichiers `memento-note/locales/*.json` (FR et EN comme références de contenu) ; éviter le texte en dur ; traductions **contextuelles** (sens produit, pas mot à mot — ex. « connecter votre propre fournisseur ») ; lors d'une traduction complète, mettre à jour toutes les locales concernées ; si l'utilisateur demande seulement les **clés i18n**, ajouter les clés (souvent EN/FR) sans remplir les 15 locales — il traduit souvent avec un autre modèle.
+- Interface : tout libellé via i18n dans les 15 fichiers `memento-note/locales/*.json` (FR et EN comme références de contenu) ; éviter le texte en dur ; traductions **contextuelles** (sens produit, pas mot à mot — ex. « connecter votre propre fournisseur ») ; libellés FR **lisibles** (éviter jargon non expliqué : « wiki », « embed », etc.) et **aide contextuelle** où l'UX l'exige ; lors d'une traduction complète, mettre à jour toutes les locales concernées ; si l'utilisateur demande seulement les **clés i18n**, ajouter les clés (souvent EN/FR) sans remplir les 15 locales — il traduit souvent avec un autre modèle.
- Base de données : **INTERDIT TOTALEMENT** de lancer `prisma db push --force-reset`, `prisma migrate reset`, `DROP TABLE`, `TRUNCATE`, `pg_restore` avec clean, ou TOUTE commande qui vide/supprime des données — MÊME SI l'utilisateur est d'accord — sans avoir d'abord : (1) dumpé la base avec `bash /home/devparsa/dev/Momento/dump-db.sh`, (2) vérifié le dump fait au moins 1Mo, (3) obtenu un "OUI" explicite de l'utilisateur. **4 incidents de perte de données documentés (14/05, 15/05 x2, 16/05). NE JAMAIS REFAIRE ÇA.**

NE JAMAIS REFAIRE ÇA.**
- Design produit : migration depuis les gabarits `architectural-grid1` (base cible) et `architectural-grid` ; avancer pas à pas avec validation ; respecter la logique liste / carte de notes puis contenu au clic comme dans la référence.
+- Design produit : migration depuis `architectural-grid1` (base) et `architectural-grid` (prototype UI courant) ; **consulter le prototype avant toute implémentation UI** ; logique liste/carte puis contenu au clic ; parité actions liste/carte (menus « … », déplacer, génération SVG, etc.) ; contraste éditeur clair / sidebar sombre ; retirer thèmes obsolètes ; **pas de refresh/revalidation complets inutiles** (aligné prototype — mutations optimistes, pas de `revalidatePath` systématique ni resync depuis `initialNotes`) ; **Memory Echo en section inline dans l'éditeur** (pas l'ancienne modale) — similarité sur contenu **représentatif** (pas de troncature arbitraire type 200/800 car.) ; **recherche (sidebar / résultats, ex. flux « ouvrir la note ») et navigation liste des notes** (modes affichage, icônes vs initiales…) : suivre **`SearchModal` et les patterns actuels** dans `architectural-grid`, pas une approximation ou un ancien flux ; **sidebar rail** (`sidebar.tsx`) : une seule icône active ; **largeur sidebar responsive** (`components/sidebar.tsx`) — `w-80` (320px) de base, plus large en `xl`/`2xl` (grands écrans) ; garder le fallback `Suspense` de `app/(main)/layout.tsx` **aligné** sur ces largeurs (rail fixe 54px) ; `activeView` synchronisé avec pathname et query (`/insights`, `/revision`, `/home?reminders=1`) ; panneau latéral contextuel par route (pas la liste carnets sur `/insights` ou Rappels) ; **`/insights` (insights sémantiques)** : suivre **`InsightsView.tsx` + graphe réseau associé dans le prototype** (ex. composition type `NetworkGraph.tsx`) ; **distincte de `/graph`** ; ne pas substituer par une UX « géométrique » décorative ou un regroupement par carnet hors spec prototype ; lorsque données clusters en retard ou partiellement périmées, **montrer l’état dégradé exploitable plutôt qu’une page vide** ; si l'utilisateur hésite entre variantes UX, **trancher pour le design prototype** plutôt que multiplier les toggles.
- Contraste éditeur clair face à une sidebar plus sombre ; fiabiliser la navigation du sidebar en s'alignant sur la logique des dossiers de référence design.
+- Locale persane : dates en calendrier iranien (conversion), chiffres persans, et vérification RTL/positionnement global (app **et** extension Web Clipper) ; **Memory Echo** et recherche sémantique doivent fonctionner en persan (RTL, embeddings — pas de contournement « EN only ») ; attention à ne pas confondre un nom de carnet (ex. « Persan ») avec le libellé de langue.
 - Retirer les traces de bleu ou de thème obsolètes ; harmoniser les couleurs des vues (ex. Agents) avec le design courant ; revoir la cohérence des options de thème dans les paramètres.
 - Locale persane : dates en calendrier iranien (conversion), chiffres persans, et vérification RTL/positionnement global ; attention à ne pas confondre un nom de carnet (ex. « Persan ») avec le libellé de langue.
 - Flux Excalidraw / diagrammes générés : accès via notification en plus d'une simple redirection ; priorité à la mise en page et au texte contenu dans les formes ; proposer des modes visuels (ex. coloré vs plus austère) tout en visant un rendu proche du style Excalidraw (polices, look).
 - L'admin doit être intégré au nouveau design (éviter l'ancienne topbar isolée).
 - Ne pas supposer les réglages utilisateur (modes, options) sans preuve dans l'UI ou les données.
 - **Interdiction d'écrire des tests** sauf demande explicite ; en CI, seul `npm run test:unit` (`tests/unit/**`) — pas `tests/migration/` ; ne jamais générer de code superflu.
- Déploiement : privilégier le chemin rapide (artifact Next.js en CI + `Dockerfile.prebuilt`) ; éviter les rebuild Docker complets inutiles (~15 min par itération).
+- Déploiement : privilégier le chemin rapide (artifact Next.js en CI + `Dockerfile.prebuilt`) ; CI/CD très robuste (pas d'image Docker obsolète en prod, pas de migrations/schéma DB via le workflow deploy) ; éviter les rebuild Docker complets inutiles (~15 min par itération) ; **ne pas pousser un déploiement quand des features clés sont inachevées** ; ne pas insister sur le déploiement tant que le produit n'est pas fini ou meilleur. **CI/CD Gitea spécifique** : (1) `actions/upload-artifact` et `download-artifact` doivent utiliser **@v3** (pas @v4 — non supporté par Gitea, erreur `GHESNotSupportedError`) ; (2) `Dockerfile.socket.prebuilt` doit utiliser `--legacy-peer-deps` dans `npm install` (conflit TipTap 3.22.5 vs 3.23.6) ; (3) le serveur de prod (192.168.1.190) **ne peut pas pull Docker Hub** (DNS cassé) — le build Docker complet échoue, seul le chemin prebuilt artifact fonctionne ; (4) `docker-entrypoint.sh` applique les migrations Prisma **avant** de démarrer le serveur Next.js (ordre correct) ; (5) rollback d'urgence : `docker tag memento-memento-note:rollback memento-memento-note:latest && docker compose up -d --force-recreate memento-note` ; (6) `scripts/deploy-prod.sh` charge `/opt/memento/.env.docker` via un **parseur robuste ligne-par-ligne** (jamais `source` — crash `unexpected EOF` sur guillemet non fermé) et teste Postgres avec `pg_isready` + credentials **du conteneur** (`$POSTGRES_USER` interne) ; (7) lint CI = `eslint --max-warnings 9999` : les **warnings ne bloquent pas**, seules les **erreurs** bloquent (ex. `no-html-link-for-pages` → `<Link>` obligatoire pour la navigation interne, pas `<a href="/">`) ; **TRAVAILLER SUR UNE BRANCHE** pendant le dev, ne push sur `main` que quand le code est testé et fonctionnel — chaque push sur `main` déclenche un déploiement automatique en production.
 - Authentification : priorité à l'inscription/connexion via **Google OAuth** (plutôt qu'un compte email/mot de passe) ; exiger une vraie déconnexion (invalidation session/cookies — pas de reconnexion implicite, y compris en navigation privée).
 - Priorité absolue à la qualité UX, même si l'implémentation est complexe (« je m'en fous si c'est complexe ») ; **ne jamais affirmer qu'un correctif ou une feature est fait sans vérification réelle** (app, prototype `architectural-grid`, ou test), **notamment navigation recherche/liste notes et vue `/insights` vs fichiers prototype** — l'utilisateur sanctionne fermement les fausses déclarations ; **ouverture note liée depuis l'éditeur** (ex. bloc live « Ouvrir ») : **split peek inline** animé (`lib/note-peek-sync.ts`, `note-editor-split-peek.tsx` — éditeur courant à **gauche**, note liée en lecture seule à **droite** en LTR ; **inversé en RTL** `fa`/`ar`), **pas nouvel onglet** ; **ne jamais annuler du code non commité** (`git checkout`, reset fichier) **sans demande explicite** (perte de travail documentée, ex. drag handle éditeur) ; **ne jamais remettre du code que l'utilisateur a explicitement retiré sans demander d'abord** (ex. `reserveUsageOrThrow` retiré intentionnellement de `organize-notebook.ts` — agent l'a remis sans demander → user mécontent) ; **correction i18n ou spec doc** : **ne pas refondre logique/UI** hors scope (ex. US-4 `structuredViewBlock` — garder le dual-mode base locale + lien carnet, pas de suppression du mode local) ; en frustration ou pour déléguer, **prévoir des prompts / briefs d'implémentation détaillés** (autre modèle ou dev), en plus des briefs outil de design.
 - Livraison : **une user story à la fois**, tester et valider avec l'utilisateur avant la suivante (pas d'auto-validation ni d'enchaînement de code non demandé) ; suivi dans `docs/user-stories.md` ; briefs pour outil de design externe sur demande ; **avant de développer une story, vérifier d'abord dans le code si la feature existe déjà** — les docs de stories (`docs/story-nextgen-editor.md`, `docs/user-stories.md`) sont **souvent périmés** (features livrées mais marquées « à faire »).
 - **Facturation & quotas IA** : limites mensuelles, tiers (BASIC/PRO/BUSINESS/ENTERPRISE) et Price IDs Stripe via **Admin > Facturation & quotas** (`/admin/billing`) — pas via `.env` pour le métier ; secrets Stripe (`STRIPE_SECRET_KEY`, webhook) restent en env serveur ; doc `memento-note/docs/admin-billing-quotas-guide.md`.
 ## Learned Workspace Facts
 - Application Next.js principalement sous `memento-note/`.
- Référentiels design du workspace : `architectural-grid1/` et `architectural-grid/` à la racine du repo Momento.
+- Référentiels design du workspace : `architectural-grid1/` et `architectural-grid/` à la racine du repo Memento.
 - i18n : 15 fichiers sous `memento-note/locales/` (de, en, es, fr, it, pt, nl, pl, ru, zh, ja, ko, ar, fa, hi) ; logique sous `memento-note/lib/i18n/` ; référence `en.json` (~2218 clés) ; auditer les « non traduits » par flatten EN vs locale (souvent valeurs identiques à l'EN).
- Workflow BMad : stories sous `docs/` (ex. `3-4-host-pays-session-logic.md`), suivi sprint dans `docs/sprint-status.yaml` ; skills sous `.claude/skills/bmad-*` ; `_bmad-output/planning-artifacts` souvent vide — planification de référence dans `docs/`.
+- Workflow BMad : stories sous `docs/` (ex. `3-4-host-pays-session-logic.md`), suivi sprint dans `docs/sprint-status.yaml` et stories courantes dans `docs/user-stories.md` ; skills sous `.claude/skills/bmad-*` ; `_bmad-output/planning-artifacts` souvent vide — planification de référence dans `docs/` ; préférer **une user story par feature** (pas de stories groupées).
- PostgreSQL Docker (`memento-postgres`) sur le port 5433 ; Redis Docker (`memento-redis`) sur le port 6379 (voir règles projet).
+- PostgreSQL Docker (`memento-postgres`) port 5433 ; Redis (`memento-redis`) port 6379 ; règles Prisma/DB dans `CLAUDE.md`.
- Règles opérationnelles Prisma et sécurité base de données décrites dans `CLAUDE.md` à la racine du repo.
+- **Admin facturation** : page `/admin/billing` (`billing-admin-client.tsx`, actions `admin-billing.ts`) — quotas par feature IA et config Stripe métier en base, effet ~60 s ; guide `memento-note/docs/admin-billing-quotas-guide.md`.
- Production : dépôt `/opt/memento` sur `192.168.1.190`, conteneur `memento-note` sur le port **3000**, URL publique **https://note.parsanet.org** (nginx + Cloudflare) ; ne pas recréer Postgres en prod (`deploy.yaml` / `deploy-prod.sh`).
+- Production : dépôt `/opt/memento` sur `192.168.1.190`, conteneur `memento-note` sur le port **3000**, URL publique **https://memento-note.com** (nginx + Cloudflare ; ancien domaine note.parsanet.org) ; `NEXTAUTH_URL` aligné sur ce domaine ; email sortant via **Resend** (`SMTP_FROM` ex. `noreply@memento-note.com`, domaine vérifié sur resend.com) ; deploy (`deploy.yaml` / `deploy-prod.sh`) **sans toucher Postgres** (pas de `postgresql-client`, pas de migrations auto en prod).
 - CI/CD Gitea : `.gitea/workflows/ci.yaml` — CI sur `ubuntu-24.04`, deploy sur runner **`docker-host`** (sur le serveur) ; deploy manuel via `.gitea/workflows/deploy.yaml` ou `bash scripts/deploy-prod.sh`.
- Migrations dans l'image prebuilt : `docker compose exec memento-note node ./node_modules/prisma/build/index.js migrate deploy` (pas `npx prisma` dans le PATH) ; helper `scripts/migrate-docker.sh`.
+- Migrations prebuilt + vérif deploy : `docker compose exec memento-note node ./node_modules/prisma/build/index.js migrate deploy` (pas `npx prisma`) ; helper `scripts/migrate-docker.sh` ; `GET /api/build-info` (SHA Git) ; comparer `127.0.0.1:3000` et domaine Cloudflare — purger cache si versions divergent ; 403 `/api/manifest` côté domaine = souvent Cloudflare.
- Vérification deploy : `GET /api/build-info` (SHA Git) ; comparer `127.0.0.1:3000` et le domaine Cloudflare — purger le cache si versions divergent ; 403 sur `/api/manifest` côté domaine = souvent Cloudflare, pas l'app.
+- Éditeur riche : `rich-text-editor.tsx` — `immediatelyRender: false` ; activer **`shouldRerenderOnTransaction: false`** (quick win perf TipTap 2.5) ; **drag handle / menu bloc** via **`@tiptap/extension-drag-handle-react`** (spec officielle — pas de double plugin `DragHandleExtension` + composant React, pas de repositionnement maison) ; poignée dans **colonne gutter fixe** du wrapper (padding + `getReferencedVirtualElement`), pas sur le bord des listes/numéros ; CSS : **pas `opacity:0` sur `.drag-handle`** (visibilité gérée par le plugin) ; config/callbacks **stables hors composant** ; fondation blocs : `tiptap-unique-id-extension.ts` / **`data-id` persisté à la sauvegarde** (références « Copier la référence ») ; **Smart Paste** : `lib/editor/smart-paste-extension.ts` ; **peek split** note source : `lib/note-peek-sync.ts` + `note-editor-split-peek.tsx` ; **conversion markdown → texte enrichi** : un **seul** convertisseur `lib/markdown-to-html.ts` (`markdownToHtml`, gfm+breaks) + une **action atomique** `convertToRichText(html)` dans `note-editor-context.tsx` (applique le HTML **immédiatement** via `setContentImmediate` — pas le `setContent` débouncé 800ms — et bascule `isMarkdown=false`) ; toolbar (`handleConvertToRichtext`) **et** chat IA contextuel (`contextual-ai-chat.tsx`, action `toRichText` → `/api/ai/convert-markdown`) passent par cette action unique (ne pas dupliquer la conversion ni oublier de basculer `isMarkdown`) ; **US-4 `structuredViewBlock`** (`tiptap-structured-view-block-extension.tsx`, `structured-view-block-embed.tsx`) : **dual-mode** — base locale autonome par défaut (`/database`, `/vue`, `isLocal: true`) + option « Lier à un carnet » (Structured Views) ; i18n `structuredViewBlock.*` ; **rejeté** : ancien `databaseBlock` « Auteurs & Œuvres » et spec embed-only `docs/story-nextgen-editor-us4-redesign.md` ; epic active `docs/story-nextgen-editor.md` — priorité **PERF > NEXTGEN > UX > MOBILE > MARKDOWN**.
- Guide utilisateur illustré : `docs/guide-utilisateur/README.md`, captures dans `docs/guide-utilisateur/screenshots/` ; régénération via `docs/guide-utilisateur/capture-screenshots.mjs` lancé depuis `memento-note/` (Playwright) ; URL lue depuis `NEXTAUTH_URL` ou `MOMENTO_DOC_BASE_URL`.
+- Sync mutations notes entre composants : `memento-note/lib/note-change-sync.ts` (`emitNoteChange`, événement `NOTE_CHANGE_EVENT`) ; tracking quotas IA : événement `ai-usage-changed` (window) — doit être dispatché depuis **tous** les points d'appel IA (recherche sémantique, auto-tag, auto-title, chat, reformulation, analyse carnet, etc.) ; UI quotas : `usage-meter.tsx` (polling 5s + écoute événement).
 - Roadmap / écart prototype vs prod : Web Clipper — **`ClipperSimulator.tsx` = référence design uniquement** (pas de simulateur en prod) ; extension **`memento-note/extension/`** v0.3 **Side Panel** (clip page/sélection/lien ; popup Chrome se ferme au clic page — Side Panel pour la sélection) ; i18n extension **15 langues** (`_locales/`, détection locale navigateur ; script `extension/i18n/generate-translations.cjs`) ; **`host_permissions`** incl. LAN ; **URL serveur configurable en dev**, adresse prod figée en release ; cookies/session alignés avec l'instance cible ; **Flashcards IA SM-2 livrées** : `/revision`, `/api/flashcards/*`, génération depuis l'éditeur (GraduationCap) — réf. prototype `RevisionView.tsx` ; **Structured Views partiellement livrées** : schéma par carnet, Table/Kanban, champs partagés et valeurs par note (`/home` + toolbar carnet) — **suivi de tâches par carnet via Kanban structuré** (pas de vue agrégée Notes/Tâches sur la home ; cases à cocher inline dans les notes) ; **Éditeur Next-Gen livré** (doc `docs/story-nextgen-editor.md` **périmé** — vérifier le code) : US-1 poignée gutter unique (`editor-block-drag-handle.tsx` + `lib/editor/global-drag-handle-extension.ts`, extension Novel `tiptap-extension-global-drag-handle`), US-2 menu action bloc (`block-action-menu.tsx`), US-3 Smart Paste transclusion (`smart-paste-extension.ts` + `smart-paste-menu.tsx`), US-4 database inline (`structuredViewBlock`), plus `data-id` / `liveBlock` / peek split ; **`/insights` livré** : `app/(main)/insights/page.tsx` + `network-graph.tsx` (clusters sémantiques, bridge notes ; **≠ `/graph`**) ; **US-TEMPORAL reporté** ; encore en gap : transclusion bidirectionnelle complète, graphe knowledge enrichi (`GraphKnowledgeMap.tsx`) ; publication **Chrome Web Store** : icônes 16/48/128, privacy policy, `host_permissions` prod restreints vs build dev ; **Wizards** : `NotebookOrganizerDialog` (tags/doublons) branché via bouton "Tags IA" dans `home-client.tsx` — `StructuredViewsWizard` encore **orphelin** (pas de point d'entrée UI) ; **Publication web** (`note-editor-toolbar.tsx`) : deux modes — simple (copie directe) + IA (2-3 templates, reformulation adaptée au contenu, KaTeX pour équations, images incluses) — quota IA consommé uniquement sur publication IA ; **champs DB publication** sur modèle `Note` : `publicSlug` (pas `publishedSlug`), `publishedContent` (pas `publishedHtml`) — `publishMode` est paramètre API uniquement (`mode: 'simple' | 'ai'`), **pas** un champ en base.

-**ESLint config strategy:** Use the flat config format (`eslint.config.mjs`) with Next.js core-web-vitals + TypeScript strict rules.

Lint now passes with only warnings (34 `react-hooks/exhaustive-deps`) and 4 fixable errors in `extension/i18n/generate-translations.cjs`.

 ## Intent
 **Problem:** Users have hundreds of notes but no automatic way to discover thematic clusters or connections between unrelated topics. Notes remain siloed in notebooks, and users manually create links between related concepts across different notebooks.
 **Approach:** Implement automatic clustering using density-based algorithm (HDBSCAN equivalent) on note embeddings, detect "bridge notes" that connect multiple clusters, and provide AI-powered suggestions for missing connections. Visualize clusters graphically with a dashboard showing insights and connection opportunities.
 ## Boundaries & Constraints
 **Always:**
 - Use existing pgvector embeddings from NoteEmbedding table
 - Cluster per-user only (never cross-user data)
 - All SQL uses parameterized queries (no interpolation)
 - HDBSCAN: Node.js compatible implementation or custom density-based clustering
 - Bridge score = len(clusters_touched) / max_clusters (0-1 range)
 - Threshold for cluster membership: >= 0.3 similarity
 - Threshold for bridge detection: >= 0.5 cosine similarity to >= 2 clusters
 - Incremental recalculation only when > 5% embeddings changed or > 10 notes modified
 **Ask First:**
 - External Python microservice vs Node.js native clustering
 - Cluster auto-naming: exact LLM prompt wording
 - Dashboard UI placement: separate page vs modal vs sidebar panel
 - Visualization library: D3.js, Cytoscape.js, or React Flow
 **Never:**
 - HDBSCAN pip install (Python) — we are a Node.js stack
 - Real-time clustering on every note save
 - Cross-user cluster analysis
 - Modifying existing NoteLink or MemoryEchoInsight behavior
 - Manual cluster assignment by users (out of scope for v1)
 ## I/O & Edge-Case Matrix
 | Scenario | Input / State | Expected Output / Behavior | Error Handling |
 |----------|--------------|---------------------------|----------------|
 | CLUSTER_NEW_USER | User with < 10 notes, no existing clusters | Empty cluster list, message "Need more notes to cluster" | Return gracefully with status: insufficient_data |
 | CLUSTER_EXISTING | User with 100+ notes, embeddings exist | N clusters (3-50), each with auto-generated name | Log errors, continue with partial results |
 | BRIDGE_DETECTION | Note similar to cluster A (0.7) and cluster B (0.6) | Marked as bridge, bridge_score = 0.5, clusters_connected = [A, B] | Skip if similarity < 0.5 |
 | NO_BRIDGES | User with isolated clusters (no cross-cluster similarities) | Empty bridge list, suggestions for missing connections | Return empty array |
 | SUGGEST_CONNECTIONS | Cluster A (Recipes) and Cluster B (Health) unconnected | 3 AI-suggested bridge note ideas with titles/descriptions | Fallback to generic "Connect [A] and [B]" if LLM fails |
 | INCREMENTAL_UPDATE | 3 notes modified out of 200 | Skip recalculation (< 5% threshold) | Return cached results |
 | MAJOR_UPDATE | 15 notes modified out of 200 | Trigger full recalculation | Queue background job, return immediately |
 | EMBEDDING_MISSING | Note exists but no embedding in NoteEmbedding | Exclude from clustering | Log warning, continue with available notes |

 ## Tasks & Acceptance
 **Execution:**
 - [x] `memento-note/prisma/schema.prisma` -- Add NoteCluster and BridgeNote models with proper indexes -- Store cluster mappings and bridge metadata
 - [x] `memento-note/lib/ai/services/clustering.service.ts` -- Implement density-based clustering (HDBSCAN-style in Node.js) -- Core algorithm for automatic note grouping
 - [x] `memento-note/lib/ai/services/bridge-notes.service.ts` -- Implement bridge detection and AI suggestion generation -- Find cross-cluster connections
 - [x] `memento-note/app/api/clusters/route.ts` -- Create cluster listing and recalculation endpoints -- REST API for cluster operations
 - [x] `memento-note/app/api/bridge-notes/route.ts` -- Create bridge notes and suggestions endpoints -- REST API for bridge operations
 - [x] `memento-note/app/api/cron/clusters/route.ts` -- Create cron endpoint for scheduled recalculation -- Automated background processing
 - [x] `memento-note/components/cluster-visualization.tsx` -- Build interactive graph with cluster coloring -- Visual representation of note clusters
 - [x] `memento-note/components/bridge-notes-dashboard.tsx` -- Build insights dashboard with stats and suggestions -- User-facing cluster and bridge information
 - [x] `memento-note/app/(main)/insights/page.tsx` -- Create main insights page -- Container for visualization and dashboard
 - [x] `memento-note/lib/ai/services/clustering.service.ts` -- Add cluster auto-naming via LLM -- Human-readable cluster names
 - [x] `memento-note/lib/ai/services/bridge-notes.service.ts` -- Add incremental recalculation logic -- Efficient updates without full recompute
 **Acceptance Criteria:**
 - Given a user with 50+ notes with embeddings, when the clustering API is called, then notes are grouped into 3-20 clusters based on semantic similarity
 - Given a cluster has been created, when the cluster is viewed, then it has an auto-generated name (2-4 words) describing the common theme
 - Given a note is similar to >= 2 clusters with cosine >= 0.5, when bridge detection runs, then the note is marked as a bridge note with correct bridge_score
 - Given isolated clusters exist (no bridges), when suggestions are requested, then 3 AI-generated bridge note ideas are returned per cluster pair
 - Given the insights page is loaded, when displayed, then clusters are color-coded and bridge notes have golden borders
 - Given < 10 notes exist for a user, when clustering is requested, then API returns insufficient_data status gracefully
 - Given > 5% of notes have been modified, when the cron runs, then full recalculation is triggered
 - Given <= 5% of notes have been modified, when the cron runs, then cached results are returned
 ## Design Notes
 ### Clustering Algorithm Choice
 Since HDBSCAN is Python-only and we're a Node.js stack, we implement a simplified density-based clustering:
 1. **Pairwise similarity matrix**: Use pgvector cosine similarity for all note pairs
 2. **DBSCAN variant**: 
   - For each note, find neighbors within epsilon = 0.3 cosine distance
   - Form clusters from dense regions (min_cluster_size = 3)
   - Mark outliers as noise (cluster_id = -1)
 This approximates HDBSCAN's core benefits: no preset cluster count, outlier detection, handles varying cluster sizes.
 ### Bridge Score Formula
 ```
 bridge_score = len(clusters_touched) / max_possible_clusters
 ```
 - A note touching 2 of 5 clusters = 0.4
 - A note touching 5 of 5 clusters = 1.0 (super-connector)
 ### Cluster Naming
 Use the 5 most central notes (highest mean similarity to other cluster members) as context for LLM:
 ```
 "Here are 5 notes from a cluster. Summarize the common theme in 2-4 words:
 1. [title] - [content snippet]
 2. ..."
 ```
 ### UI Visualization
 - **Clusters**: Each cluster gets a unique hue (HSL color wheel)
 - **Bridge notes**: Golden border + 1.5x size
 - **Isolated clusters**: Grayed out with "Isolated" badge
 - **Click interaction**: Click cluster to zoom and show note list
 ### Cron Strategy
 - **Daily**: At 2 AM server time, recalculate for all active users
 - **Incremental check**: Track last_modified timestamp on embeddings; if delta < 5%, skip
 ## Verification
 **Commands:**
 - `npx prisma migrate dev --name add_clustering_support` -- Creates NoteCluster and BridgeNote tables
 - `npx prisma generate` -- Regenerates Prisma client with new models
 - `npm run build` -- Ensures TypeScript compilation succeeds
 **Manual checks:**
 - Visit /insights page — should show cluster visualization or "Need more notes" message
 - Create 30+ test notes with varied topics — check that clusters form and have sensible names
 - Modify a note and check it — clusters should update within 24h or via manual recalculate
 - Check that bridge notes are visually distinct (golden border) in visualization
 - POST /api/clusters/recalculate — should return 202 and trigger background job
 - GET /api/bridge-notes/suggestions — should return AI-generated connection ideas

 <frozen-after-approval reason="human-owned intent — do not modify unless human renegotiates">
 ## Intent
 **Problem:** The Memento workspace spans multiple deployable and reference projects (memento-note, mcp-server, extension, mobile, monitoring, CI/CD, prototypes) without a consolidated security and quality audit; several P0 issues were found (open uploads, MCP auth bypass, fail-open quotas).
 **Approach:** Deliver a prioritized cross-project audit report (bugs + improvements) and, upon approval, remediate Phase 1 P0 security items first — app uploads/auth, MCP tenant isolation, extension Store readiness — before UX/i18n/prototype parity work.
 ## Boundaries & Constraints
 **Always:** No destructive DB commands; backup via `dump-db.sh` before any schema change; i18n via 15 locales when touching UI; follow prototype `architectural-grid` for UX gaps; fail-closed for billing quotas in production.
 **Ask First:** Whether to fail-open vs fail-closed quotas during Redis outage; whether MCP `x-user-id` should be removed entirely or restricted to internal network; Chrome Web Store host_permissions scope; archiving `architectural-grid1` vs keeping both prototypes.
 **Never:** `prisma migrate reset`, `db push --force-reset`, `pg_dump --clean` in deploy scripts; exposing API keys in client bundles; shipping extension with dev `host_permissions`; implementing all audit items in one PR.
 </frozen-after-approval>
 ## Code Map
 - `memento-note/app/api/uploads/[...path]/route.ts` -- uploads served without session check
 - `memento-note/app/api/image-proxy/route.ts` -- open SSRF proxy
 - `memento-note/lib/entitlements.ts` -- Redis fail-open on AI quotas
 - `memento-note/auth.config.ts` -- `/insights`, `/graph`, `/revision`, `/support` not gated
 - `memento-note/context/notebooks-context.tsx` -- broken AI toast note move (no home refresh)
 - `mcp-server/index-sse.js` -- `x-user-id` header auth bypass
 - `mcp-server/tools.js` -- missing userId filter + `ensureUserId()` first-user fallback
 - `memento-note/extension/dist-chrome-store/` -- missing PNG icons, wide host_permissions
 - `memento-mobile/app.json` -- references missing `assets/`
 - `monitoring/metrics-token` -- placeholder secret committed
 - `scripts/deploy-prod.sh` -- `pg_dump --clean`, full Docker build fallback
 - `docker-compose.yml` -- MCP/Ollama ports bound 0.0.0.0
 ## Tasks & Acceptance
 **Execution (Phase 1 — P0 security only, if approved):**
 - [x] `memento-note/app/api/uploads/[...path]/route.ts` -- require auth + verify note ownership for file path -- prevent private attachment leak
 - [x] `memento-note/app/api/image-proxy/route.ts` -- require auth + domain allowlist -- close SSRF/abuse
 - [x] `memento-note/lib/entitlements.ts` -- fail-closed when Redis unavailable in production -- align with billing policy
 - [x] `memento-note/auth.config.ts` -- add `/insights`, `/graph`, `/revision`, `/support` to protected routes -- match API 401 behavior
 - [x] `mcp-server/index-sse.js` -- remove or restrict `x-user-id`; require API key on all tool paths -- close identity spoofing
 - [x] `mcp-server/tools.js` -- always scope queries to authenticated userId; remove `ensureUserId()` fallback -- multi-tenant isolation
 - [x] `docker-compose.yml` -- bind MCP `127.0.0.1:3001:3001` -- reduce network exposure
 **Acceptance Criteria:**
 - Given an unauthenticated request, when GET `/api/uploads/notes/{uuid}.png`, then response is 401/403
 - Given Redis down in production, when AI quota check runs, then request is denied (not unlimited)
 - Given unauthenticated browser, when navigating to `/insights`, then redirect to login
 - Given MCP request with only `x-user-id` header and no API key, when tool invoked, then 401
 - Given authenticated user A, when MCP lists notes, then only user A notes returned
 ## Spec Change Log
 ## Design Notes
 Full audit by project (2026-06-20):
 **memento-note CRITICAL:** open uploads; image-proxy SSRF; fail-open quotas; middleware gaps; XSS via `dangerouslySetInnerHTML` (published pages, peek, SVG gallery); weak mobile HMAC; broken AI toast note move.
 **mcp-server CRITICAL:** `x-user-id` spoofing; null userId returns all users' data; port 3001 public; Prisma schema drift vs main app.
 **extension CRITICAL:** Store build missing PNG icons; `host_permissions` too broad for CWS.
 **mobile CRITICAL:** missing assets folder; NativeWind configured but not installed.
 **monitoring CRITICAL:** placeholder metrics token in git; Grafana on 0.0.0.0:3002.
 **CI/CD CRITICAL:** manual deploy triggers full Docker build (fails on prod); `pg_dump --clean` in deploy script.
 **prototypes MEDIUM:** Gemini API key in Vite client bundle; port 3000 conflict; grid vs grid1 divergence.
 **Deferred phases:** P1 insights i18n + GraphKnowledgeMap; P2 editor drag-handle migration; P3 mobile EAS/CI; P4 monitoring alert cleanup.
 ## Verification
 **Commands:**
 - `cd memento-note && npm run test:unit` -- expected: pass (no regressions on touched modules)
 - Manual curl unauthenticated upload URL -- expected: 401/403 after Phase 1
 **Manual checks:**
 - Logged-out visit to `/insights` redirects to login
 - MCP tool call without API key returns 401
 ## Suggested Review Order
 **Upload access control**
 - Ownership check before serving note attachments; published notes stay public
  [`route.ts:30`](../../memento-note/app/api/uploads/[...path]/route.ts#L30)
 - Prisma lookup tying filename to note content/images
  [`upload-access.ts:4`](../../memento-note/lib/upload-access.ts#L4)
 **SSRF / image proxy**
 - Session gate + blocked private hosts on server-side fetch
  [`route.ts:6`](../../memento-note/app/api/image-proxy/route.ts#L6)
 - Shared SSRF hostname denylist
  [`ssrf-guard.ts:2`](../../memento-note/lib/ssrf-guard.ts#L2)
 **Billing quotas fail-closed**
 - Production denies when Redis is unavailable
  [`entitlements.ts:88`](../../memento-note/lib/entitlements.ts#L88)
 - Routes return 503 instead of silent fail-open
  [`route.ts:81`](../../memento-note/app/api/chat/route.ts#L81)
 **Auth middleware**
 - Protect insights, graph, revision, support routes
  [`auth.config.ts:30`](../../memento-note/auth.config.ts#L30)
 **MCP multi-tenant isolation**
 - API key only; x-user-id removed
  [`index-sse.js:291`](../../mcp-server/index-sse.js#L291)
 - Mandatory userId on all tool handlers
  [`tools.js:490`](../../mcp-server/tools.js#L490)
 **Infrastructure**
 - MCP port bound to localhost only
  [`docker-compose.yml:130`](../../docker-compose.yml#L130)
 **Tests**
 - Fail-open dev vs fail-closed prod entitlements
  [`entitlements.test.ts:145`](../../memento-note/tests/unit/entitlements.test.ts#L145)

 ## Intent
 **Problem:** TipTap DragHandle component uses `visibility: hidden/visible` to show/hide, but the CSS `.drag-handle` wrapper had `opacity: 0` which worked independently. However, the inner `.notion-drag-handle` class was styled as a standalone block without being visible when its parent `.drag-handle` was hidden. The CSS cascade meant the inner element had no intrinsic visibility logic — it only appeared to work when the parent opacity changed.
 **Approach:** Restructure the CSS so `.drag-handle` (the TipTap-managed wrapper) handles all visibility via `opacity` and `pointer-events`, and `.notion-drag-handle` (the inner content wrapper) styles only the visual appearance of the drag handle icon. The parent-child relationship is now explicit in CSS with `pointer-events: none` on the hidden state.
 ## Code Map
 - `memento-note/app/globals.css:1087-1135` -- DragHandle CSS: fix visibility cascade, add inner wrapper styles
 - `memento-note/components/rich-text-editor.tsx` -- Already uses DragHandleExtension and drag-handle-react (confirmed on disk)
 ## Tasks & Acceptance
 **Execution:**
 - [x] `memento-note/app/globals.css` -- Fix .drag-handle visibility cascade, add pointer-events, restructure inner .notion-drag-handle as child element
 **Acceptance Criteria:**
 - Given a note is open in the editor, when the user hovers over a block (paragraph, heading, list item), then the drag handle appears in the gutter with blue hover state
 - Given the drag handle is visible, when the user clicks it, then the block action menu opens
 - Given the drag handle is in its default hidden state, when the editor loads, then no drag handle is visible (opacity: 0, pointer-events: none)
 ## Spec Change Log
 <!-- Empty - one-shot fix with no review loops -->
 ## Suggested Review Order
 1. `memento-note/app/globals.css:1087-1135` -- CSS changes only; verify cascade correctness

 # Spec: GDPR Analytics Sync + Error Reporting Hardening
 ## Context
 Deferred work from Story 4.1 (GDPR Cookie Consent):
 - AC5 anonymousAnalytics DB sync was not implemented
 - Original constraint: "zero DB writes in 4.1, 100% client consent"
 - Now removing constraint to implement proper sync
 ## Goals
 1. **Primary**: Sync cookie consent `anonymousAnalytics` to database for authenticated users
 2. **Secondary**: Verify error reporting is properly wired (legitimate interest, no consent needed)
 ## Acceptance Criteria
 ### AC1: Authenticated user consent syncs to DB
 - When a logged-in user accepts/rejects analytics via banner or preferences, `UserAISettings.anonymousAnalytics` is updated in DB
 - Guest users (no session) continue using localStorage only
 ### AC2: Cross-device consistency
 - User's analytics consent persists across devices when logged in
 - Initial consent load prefers DB value when local storage is empty
 ### AC3: Error reporting verification
 - Existing error reporting continues to work without consent (legitimate interest)
 - Verify `/api/debug/client-error` route exists and is wired
 ## Tasks
 - [ ] Task 1: Create server action for consent sync
 - [ ] Task 2: Update cookie consent utilities
 - [ ] Task 3: Update banner and dialog components
 - [ ] Task 4: Verify error reporting route
 ## Code Map
 ### New/Modified Files
 | File | Change |
 |------|--------|
 | `lib/consent/cookie-consent.ts` | Add `saveConsentWithSync()` client wrapper |
 | `app/actions/cookie-consent.ts` | NEW - Server action for DB sync |
 | `components/legal/cookie-consent-banner.tsx` | Use new sync action |
 | `components/legal/cookie-preferences-dialog.tsx` | Use new sync action |
 | `app/api/debug/client-error/route.ts` | Verify exists |
 ### Design Notes
 - Server action calls `updateAISettings({ anonymousAnalytics: boolean })`
 - Client-side: combine `setConsent()` + server action in parallel
 - Server action silently succeeds for guests (no session) — component ignores result
 - Error reporting uses `/api/debug/client-error` — already exists, no consent gate needed
 ## Spec Change Log
 - 2026-05-30: Created spec for deferred AC5 implementation
 - 2026-05-30: Added error reporting verification as secondary goal

 ## Intent
 **Problem:** La vue en graphe (`NoteGraphView`) ne tire parti que de balayages de texte rudimentaires (mentions de titre, tags partagés et similarité Jaccard en mémoire qui est désactivée au-delà de 500 notes) pour tracer les liaisons. Elle ignore totalement :
 1. Les liaisons explicites manuelles créées par l'utilisateur via des WikiLinks (`[[Note]]`) et enregistrées dans la table `NoteLink` de la base de données.
 2. Les connexions sémantiques riches générées en arrière-plan par l'IA ("Memory Echo") et enregistrées dans la table `MemoryEchoInsight` de la base de données.
 Cela donne à la vue en graphe un aspect incomplet et décousu, limitant grandement la sérendipité et la découverte de connaissances.
 **Approach:** 
 1. Modifier la route API `/api/graph` pour requêter et fusionner les liaisons manuelles (`NoteLink`) et les connexions sémantiques saines non rejetées (`MemoryEchoInsight` avec `dismissed = false`).
 2. Introduire des types de liaisons explicites (`explicit_link` et `semantic_echo`) dans le flux de données de l'API.
 3. Mettre à jour le composant de rendu React `<NoteGraphView />` pour styliser et différencier visuellement ces relations clés avec des couleurs HSL premium, des épaisseurs de trait adaptées et des motifs (pleins vs. pointillés) pour enrichir l'expérience utilisateur et clarifier la structure du graphe.
 ## Boundaries & Constraints
 **Always:**
 - Filtrer rigoureusement toutes les requêtes Prisma par `userId` pour garantir l'étanchéité des données utilisateur.
 - Exclure toutes les liaisons (sources ou cibles) pointant vers des notes archivées ou envoyées à la corbeille (`trashedAt !== null`).
 - Exclure les connexions sémantiques marquées comme rejetées (`dismissed: true`).
 - Assurer un fort contraste visuel sur le graphe en harmonie avec la charte graphique premium existante (pas de couleurs agressives non maîtrisées).
 **Ask First:**
 - Faut-il plafonner le nombre total de liens sémantiques ou Jaccard affichés simultanément pour éviter de surcharger visuellement les graphes de grande taille (au-delà de 200 notes) ?
 **Never:**
 - Modifier la structure de la base de données Prisma (pas de changement de schéma).
 - Lancer de commande destructive sur la base de données (`prisma db push --force-reset` ou équivalent).
 - Supprimer ou désactiver les liaisons textuelles existantes (`title_mention`, `shared_label`, `jaccard`), qui restent d'excellents compléments de découverte.
 ## I/O & Edge-Case Matrix
 | Scenario | Input / State | Expected Output / Behavior | Error Handling |
 |----------|--------------|---------------------------|----------------|
 | HAPPY_PATH | L'utilisateur possède des notes connectées par WikiLinks et des Memory Echo Insights | L'API `/api/graph` retourne un tableau fusionné contenant des arêtes de types `explicit_link`, `semantic_echo`, `title_mention`, etc. | N/A |
 | EMPTY_STATE | Aucune liaison, aucune note | L'API retourne `{ nodes: [], edges: [], clusters: [] }` de manière propre sans planter. | Retourne des tableaux vides de manière sécurisée |
 | TRASHED_NOTES | Des liaisons (`NoteLink` ou `MemoryEchoInsight`) pointent vers des notes supprimées | Les arêtes correspondantes sont filtrées et exclues du graphe final. | Filtrage en amont lors de la construction des listes |
 | STUB_LINKS | Des wikilinks pointent vers des notes inexistantes (stubs) | Filtrage des arêtes orphelines (seuls les couples de notes existantes et valides sont renvoyés). | Ignorer l'arête si l'ID source ou cible n'est pas dans le set des notes chargées |
 ## Code Map
 - `memento-note/app/api/graph/route.ts` -- Route API GET principale assemblant la liste des nœuds, des arêtes et des clusters de carnets.
 - `memento-note/components/note-graph-view.tsx` -- Composant de rendu 2D interactif utilisant `react-force-graph-2d` pour dessiner les arêtes et les groupes.
 - `memento-note/prisma/schema.prisma` -- Fichier de schéma Prisma contenant les définitions des tables `NoteLink` et `MemoryEchoInsight`.
 ## Tasks & Acceptance
 **Execution:**
 - [x] `memento-note/app/api/graph/route.ts` -- Modifier la route pour interroger en parallèle `prisma.noteLink` et `prisma.memoryEchoInsight`, filtrer les éléments invalides/corrompus/supprimés, et les injecter avec les types `explicit_link` et `semantic_echo`.
 - [x] `memento-note/components/note-graph-view.tsx` -- Enrichir la logique de mappage des arêtes du graphe pour attribuer des styles visuels premium à chaque type de lien (WikiLinks en vert émeraude épais et plein, Échos sémantiques IA en violet pointillés, etc.).
 - [x] `memento-note/components/note-graph-view.tsx` -- Rendre la légende des carnets (clusters) interactive : ajouter un état `selectedNotebookId` pour filtrer à la volée les nœuds et arêtes du graphe. Styliser les boutons actifs/inactifs de manière premium avec des micro-animations.
 - [x] `memento-note/components/note-graph-view.tsx` -- Afficher le nom du carnet dans le panneau latéral de détail de la note sous forme de tag interactif cliquable pour isoler instantanément le carnet sélectionné.
 **Acceptance Criteria:**
 - **Given** une note A contenant un WikiLink vers une note B (`NoteLink` enregistré) et une note C sémantiquement proche de la note A (`MemoryEchoInsight` enregistré)
 - **When** l'utilisateur charge la vue en graphe
 - **Then** l'API renvoie les relations avec les types `explicit_link` et `semantic_echo`
 - **And** le visualiseur dessine le lien A-B en trait vert plein et le lien A-C en trait violet pointillé.
 ## Design Notes
 ### Configuration Visuelle des Liens dans `note-graph-view.tsx`
 Nous utiliserons les associations de couleurs et d'épaisseurs suivantes pour offrir une lisibilité optimale sur fond clair/sombre :
 ```typescript
 // Exemple de configuration stylistique
 const LINK_STYLES = {
  explicit_link: { color: '#10b981', width: 2.2, dash: false },  // Vert émeraude (WikiLink manuel)
  semantic_echo: { color: '#a78bfa', width: 1.8, dash: true },   // Violet pastel (Écho sémantique IA)
  title_mention: { color: '#f59e0b', width: 1.6, dash: false },  // Orange ambré (Mention de titre automatique)
  shared_label:  { color: '#3b82f6', width: 1.2, dash: false },  // Bleu vif (Tags partagés)
  jaccard:       { color: '#cbd5e1', width: 0.8, dash: false }   // Gris clair (Similarité sémantique simple)
 }
 ```
 Pour les pointillés (dash) dans `react-force-graph-2d`, nous adapterons l'objet du graphe ou appliquerons la configuration de rendu des lignes Canvas via l'API Native si nécessaire, ou plus simplement en les configurant élégamment dans le dessin.
 ## Verification
 **Commands:**
 - `npx tsc --noEmit` -- Vérification de l'absence totale d'erreurs de typage TypeScript dans le projet après modification.
 ## Suggested Review Order
 **Backend API & Relationships Integration**
 - Requête Prisma sécurisée pour charger en parallèle les liaisons WikiLinks (`NoteLink`) et les échos sémantiques IA (`MemoryEchoInsight`).
  [`route.ts:66`](../../memento-note/app/api/graph/route.ts#L66)
 - Priorisation des liaisons qualitatives sur les mentions textuelles et assemblage des arêtes du graphe.
  [`route.ts:161`](../../memento-note/app/api/graph/route.ts#L161)
 **Frontend Visualizations & Legend**
 - Mappage des arêtes vers les nouvelles couleurs de liaison et gestion de la propriété de pointillés.
  [`note-graph-view.tsx:112`](../../memento-note/components/note-graph-view.tsx#L112)
 - Configuration de la propriété de rendu en pointillés `linkLineDash` sur le composant ForceGraph2D.
  [`note-graph-view.tsx:278`](../../memento-note/components/note-graph-view.tsx#L278)
 - Rendu du panneau de légende des liaisons dans le coin inférieur gauche pour une expérience utilisateur premium.
  [`note-graph-view.tsx:340`](../../memento-note/components/note-graph-view.tsx#L340)
 **Interactive Filtering & Notebook Navigation**
 - Boutons de légende interactifs pour isoler ou réinitialiser le filtre par carnet à la volée.
  [`note-graph-view.tsx:342`](../../memento-note/components/note-graph-view.tsx#L342)
 - Tag cliquable dans le panneau latéral de détails pour isoler instantanément le carnet associé.

 title: MCP Server Robustness Improvements
 status: done
 priority: high
 completedDate: 2026-05-24

 # Spec: MCP Server Robustness Improvements
 ## Context
 Memento currently uses MCP SDK v1.0.4 with a working but potentially fragile implementation. With MCP SDK v2 coming in Q1 2026, we need to:
 1. Make the current implementation more robust
 2. Prepare for v2 migration
 3. Add production-ready features
 ## Goals
 1. **Error Handling**: Add structured error responses and recovery mechanisms
 2. **Observability**: Add metrics, logging, and health monitoring
 3. **Performance**: Add rate limiting, request queuing, and response caching
 4. **Security**: Add request validation, input sanitization, and audit logging
 5. **Testing**: Add comprehensive test suite
 6. **Documentation**: Improve API documentation and examples
 ## Tasks
 ### 1. Error Handling & Resilience
 **File**: `mcp-server/errors.js` (new)
 ```javascript
 // Structured error codes
 export const McpErrors = {
  INVALID_INPUT: { code: -32600, message: 'Invalid Request' },
  NOT_FOUND: { code: -32601, message: 'Tool not found' },
  DATABASE_ERROR: { code: -32603, message: 'Internal error' },
  RATE_LIMITED: { code: 429, message: 'Rate limit exceeded' },
  AUTH_FAILED: { code: 401, message: 'Authentication failed' },
 }
 // Error response wrapper
 export function mcpError(code, detail) {
  return {
    content: [{ type: 'text', text: JSON.stringify({
      error: true,
      code,
      message: McpErrors[code]?.message || 'Unknown error',
      detail,
      timestamp: new Date().toISOString(),
    }) }],
  }
 }
 ```
 **File**: `mcp-server/index-sse.js`
 - Add try-catch around all tool handlers
 - Add circuit breaker for database connections
 - Add graceful degradation when DB is unavailable
 - Add request timeout enforcement
 ### 2. Observability
 **File**: `mcp-server/metrics.js` (new)
 ```javascript
 export const metrics = {
  requests: { total: 0, byTool: {}, byStatus: {} },
  errors: { total: 0, byType: {} },
  latency: { p50: 0, p95: 0, p99: 0 },
  auth: { successes: 0, failures: 0 },
 }
 export function recordRequest(tool, status, latency) {
  metrics.requests.total++
  metrics.requests.byTool[tool] = (metrics.requests.byTool[tool] || 0) + 1
  metrics.requests.byStatus[status] = (metrics.requests.byStatus[status] || 0) + 1
  // Update latency percentiles
 }
 export function getMetrics() {
  return { ...metrics, uptime: process.uptime() }
 }
 ```
 **Add endpoints**:
 - `GET /metrics` - Export metrics in Prometheus format
 - `GET /healthz` - Detailed health check (DB, cache, auth)
 - `GET /debug/connections` - Active connections info
 ### 3. Performance
 **File**: `mcp-server/rate-limit.js` (new)
 ```javascript
 import { LRUCache } from 'lru-cache'
 const rateLimits = new LRUCache({
  max: 1000,
  ttl: 60000, // 1 minute
 })
 export function checkRateLimit(identifier, limit = 100) {
  const key = `rl:${identifier}`
  const current = rateLimits.get(key) || 0
  if (current >= limit) return false
  rateLimits.set(key, current + 1)
  return true
 }
 ```
 **Add to `index-sse.js`**:
 - Apply rate limiting per API key
 - Add request queuing for concurrent requests
 - Add response caching for read-only tools (get_notes, get_notebooks)
 ### 4. Security
 **File**: `mcp-server/validation.js` (new)
 ```javascript
 import { z } from 'zod'
 export const noteIdSchema = z.string().min(1).max(100).regex(/^[a-zA-Z0-9_-]+$/)
 export const titleSchema = z.string().min(1).max(500)
 export const contentSchema = z.string().max(1000000) // 1MB limit
 export const colorSchema = z.enum(['default', 'red', 'orange', 'yellow', 'green', 'teal', 'blue', 'purple', 'pink', 'gray'])
 export const notebookIdSchema = z.string().uuid()
 export function validateToolInput(toolName, input) {
  // Validate based on tool schema
  return { valid: true, errors: [] }
 }
 ```
 **Add audit logging**:
 - Log all tool invocations with user, timestamp, parameters
 - Store audit logs in `systemConfig` or separate table
 - Add `GET /audit/logs` endpoint (admin only)
 ### 5. Testing
 **File**: `mcp-server/test/tools.test.js` (new)
 ```javascript
 import { describe, it, expect } from 'vitest'
 import { registerTools } from '../tools.js'
 describe('MCP Tools', () => {
  it('create_note should create a note', async () => {
    // Test implementation
  })
  it('get_notes should filter by notebook', async () => {
    // Test implementation
  })
  it('should handle invalid input gracefully', async () => {
    // Test implementation
  })
 })
 ```
 **Add tests for**:
 - All tool handlers
 - Authentication flows
 - Rate limiting
 - Error scenarios
 ### 6. Documentation
 **Update files**:
 - `mcp-server/README.md` - Add all tools with examples
 - `mcp-server/MIGRATION.md` - Guide for v1 to v2 migration
 - `memento-note/docs/mcp-integration.md` - User-facing guide
 ### 7. Configuration
 **File**: `mcp-server/config.js` (new)
 ```javascript
 export const config = {
  port: parseInt(process.env.PORT) || 3001,
  databaseUrl: process.env.DATABASE_URL,
  requireAuth: process.env.MCP_REQUIRE_AUTH === 'true',
  logLevel: process.env.MCP_LOG_LEVEL || 'info',
  requestTimeout: parseInt(process.env.MCP_REQUEST_TIMEOUT) || 30000,
  rateLimit: parseInt(process.env.MCP_RATE_LIMIT) || 100,

 }
 export function validateConfig() {
  const errors = []
  if (!config.databaseUrl) errors.push('DATABASE_URL is required')
  return errors
 }
 ```
 ## Dependencies
 - None - can be implemented incrementally
 ## Success Criteria
 1. All tool handlers have structured error responses
 2. `/metrics` endpoint returns useful metrics
 3. Rate limiting prevents abuse
 4. All inputs are validated before processing
 5. Test coverage > 80% for critical paths
 6. Documentation is complete and accurate
 ## Migration Path for SDK v2 (Q1 2026)
 When SDK v2 is released:
 1. Update `@modelcontextprotocol/sdk` to v2
 2. Update transport initialization
 3. Update tool registration API
 4. Update error handling to new schema
 5. Run all tests to verify compatibility
 6. Update documentation for v2 features
 ## Implementation Order
 1. Error handling (blocking, high impact) ✅
 2. Configuration validation (blocking, high impact) ✅
 3. Observability metrics (non-blocking, high value) ✅
 4. Input validation (non-blocking, security) ✅
 5. Rate limiting (non-blocking, security) ✅
 6. Testing (non-blocking, quality) ✅
 7. Documentation (ongoing) ✅

 ## Intent
 **Problem:** Subscription tiers, AI quotas, and Stripe business config are split between hardcoded code (`TIER_LIMITS`), server `.env` (price IDs, billing flag), and a minimal admin override (tier dropdown only). Operators cannot adjust limits or billing settings without redeploy; quota enforcement has a TOCTOU race (`check` then `increment`); token analytics are partially broken.
 **Approach:** Add a secure admin **Billing & Quotas** console backed by DB (`PlanEntitlement` + `SystemConfig`), keep Stripe secrets in infra env only, unify quota enforcement on atomic `reserveUsageOrThrow`, and expose usage dashboards with audit logging for manual tier overrides.
 ## Boundaries & Constraints
 **Always:**
 - `STRIPE_SECRET_KEY` and `STRIPE_WEBHOOK_SECRET` stay in server env / secrets vault — never in `SystemConfig`, never editable from browser.
 - Stripe remains authoritative for paid subscriptions; webhooks drive state; manual admin tier changes are support overrides only.
 - Quota gating unit stays **requests per feature per calendar month** (not token-based blocking).
 - Redis quota checks fail-open with structured error logging (industry standard for AI rate limits).
 - All admin mutations require `role === ADMIN`; i18n for new UI strings in `locales/en.json` and `locales/fr.json` minimum.
 - Non-destructive DB migration only; seed `PlanEntitlement` from current `TIER_LIMITS` defaults.
 **Ask First:**
 - Adding new Prisma models beyond `PlanEntitlement` (e.g. full `FeatureFlag` wiring).
 - Changing Stripe products/prices in live Stripe Dashboard (ops action, not code).
 - Switching to usage-based Stripe Meter / Metronome billing.
 **Never:**
 - Store `sk_*` or `whsec_*` in plaintext DB or admin forms.
 - Run `prisma migrate reset`, `db push --accept-data-loss`, or any destructive DB command.
 - Replace Redis real-time counters with synchronous PostgreSQL writes on every AI request.
 - Add automated tests unless explicitly requested later.
 ## I/O & Edge-Case Matrix
 | Scenario | Input / State | Expected Output / Behavior | Error Handling |
 |----------|--------------|---------------------------|----------------|
 | Admin saves tier limit | ADMIN edits PRO `chat` limit 50→75 | `PlanEntitlement` upserted; next `getLimit()` returns 75; existing Redis counters unchanged until period rollover | 403 if non-admin; 400 if invalid feature or negative limit |
 | Admin saves Stripe price ID | ADMIN sets `STRIPE_PRICE_PRO_MONTHLY` in SystemConfig | `resolvePriceId('PRO','month')` reads DB value; env used only as fallback | 400 if empty when billing enabled |
 | User at quota | User on BASIC, 30/30 `semantic_search` used | `reserveUsageOrThrow` returns 402 `QUOTA_EXCEEDED` | Fail-open if Redis down (allow + log alert) |
 | Concurrent AI requests | Two requests at limit−1 | Only one succeeds; second gets 402 (atomic Lua) | N/A |
 | Admin manual tier override | ADMIN sets user to BUSINESS | `Subscription` upserted; `AuditLog` entry with actor, target, old/new tier | Cannot override own tier (existing rule) |
 | Billing disabled | `BILLING_ENABLED=false` in SystemConfig | `/settings/billing` shows disabled state; checkout buttons hidden | N/A |
 | suggest-charts usage | Successful chart suggestion | `incrementUsageAsync` called once (not broken 4-arg call) | N/A |
 </frozen-after-approval>
 ## Code Map
 - `memento-note/prisma/schema.prisma` — add `PlanEntitlement` model (`tier`, `feature`, `limitValue`; unique on `[tier, feature]`; `null` limitValue = unlimited; omit row or sentinel = feature unavailable per tier)
 - `memento-note/prisma/migrations/*` — additive migration + seed from current `TIER_LIMITS`
 - `memento-note/lib/entitlements.ts` — load limits from DB with in-memory cache (TTL ~60s) and hardcoded fallback; export `getLimit()` async; keep fail-open on Redis errors
 - `memento-note/lib/billing/stripe-prices.ts` — read price IDs via `getConfigValue()` with env fallback; remove sole dependence on `process.env`
 - `memento-note/lib/config.ts` — add billing keys to `ENV_FALLBACKS` (`BILLING_ENABLED`, four `STRIPE_PRICE_*`)
 - `memento-note/app/actions/admin-billing.ts` — server actions: `getPlanEntitlements`, `updatePlanEntitlement`, `updateBillingConfig`, `getUsageOverview`
 - `memento-note/app/(admin)/admin/billing/page.tsx` — admin UI: tier limits matrix, billing config, usage summary table
 - `memento-note/app/(admin)/admin/billing/billing-admin-form.tsx` — client form component
 - `memento-note/components/admin-sidebar.tsx` — nav link `/admin/billing`
 - `memento-note/app/actions/admin.ts` — log `SUBSCRIPTION_OVERRIDE` audit on `updateUserSubscription`
 - `memento-note/lib/audit-log.ts` — extend `AuditAction` with `SUBSCRIPTION_OVERRIDE`, `BILLING_CONFIG_UPDATED`, `PLAN_ENTITLEMENT_UPDATED`
 - `memento-note/components/settings/billing-plans.tsx` — read `billingEnabled` from `/api/billing/status` instead of build-time env only
 - `memento-note/app/api/billing/status/route.ts` — include `billingEnabled` from SystemConfig
 - `memento-note/app/api/ai/suggest-charts/route.ts` — fix usage tracking (use `incrementUsageAsync`, not broken `trackFeatureUsage` call)
 - AI routes using `checkEntitlementOrThrow` + `incrementUsageAsync` — migrate to `reserveUsageOrThrow` only (remove duplicate increment on success); include chat route
 ## Tasks & Acceptance
 **Execution:**
 - [x] `prisma/schema.prisma` + migration — add `PlanEntitlement`, seed defaults from `TIER_LIMITS` — DB-backed limits without breaking existing users
 - [x] `lib/entitlements.ts` — async limit loader with cache + fallback; update `canUseFeature`, `reserveUsageOrThrow`, `getUserQuotas` — single source of truth
 - [x] `lib/billing/stripe-prices.ts` + `lib/config.ts` — SystemConfig-backed price IDs and `BILLING_ENABLED` — admin-editable business config
 - [x] `app/actions/admin-billing.ts` — CRUD entitlements + billing config + usage overview query (join `UsageLog` + Redis snapshot) — secure admin API surface
 - [x] `app/(admin)/admin/billing/*` + `components/admin-sidebar.tsx` — admin UI section — operator-facing management
 - [x] `app/actions/admin.ts` + `lib/audit-log.ts` — audit trail for tier overrides and config changes — support accountability
 - [x] AI routes (grep `checkEntitlementOrThrow`) + `app/api/chat/route.ts` — switch to `reserveUsageOrThrow`; drop redundant `incrementUsageAsync` on success — fix TOCTOU race
 - [x] `app/api/ai/suggest-charts/route.ts` — fix broken usage call — restore quota accounting
 - [x] `app/api/billing/status/route.ts` + `components/settings/billing-plans.tsx` — runtime billing flag — no redeploy to toggle billing UI
 - [x] `locales/en.json` + `locales/fr.json` — i18n keys under `admin.billing.*` — FR/EN reference labels
 **Acceptance Criteria:**
 - Given an ADMIN on `/admin/billing`, when they change PRO `chat` limit and save, then a new entitlement check within 60s reflects the new limit without app restart.
 - Given a BASIC user at quota, when two parallel AI requests arrive, then at most one succeeds and the other returns HTTP 402.
 - Given `BILLING_ENABLED` is false in SystemConfig, when a user opens `/settings/billing`, then checkout/upgrade actions are hidden and a clear disabled message is shown.
 - Given an ADMIN changes a user's tier from `/admin/users`, when the change succeeds, then an `AuditLog` row records actor, target user, old tier, and new tier.
 - Given Stripe price IDs are set in SystemConfig (env unset), when checkout is initiated, then the correct Stripe price is used.
 - Given Redis is unreachable, when an AI request is made, then the request is allowed (fail-open) and an error is logged server-side.
 - Given `STRIPE_SECRET_KEY` remains env-only, when inspecting `SystemConfig` table, then no `sk_` or `whsec_` values exist.
 ## Design Notes
 **PlanEntitlement limit encoding:** `limitValue: null` → unlimited; positive integer → monthly request cap; omit row (or explicit `-1` sentinel if needed) → feature not available on tier (maps to current `undefined` in `TIER_LIMITS`).
 **Cache invalidation:** After admin saves entitlements, call a small `invalidateEntitlementCache()` so changes apply immediately without waiting for TTL.
 **Quota migration pattern:** Replace `await checkEntitlementOrThrow(userId, feature)` + `incrementUsageAsync(...)` with `await reserveUsageOrThrow(userId, feature)` at request start. Do not increment again on success. For streaming chat, reserve before `streamText`; no post-finish increment.
 **Usage dashboard:** Show per-tier aggregate from `UsageLog` (last synced month) plus optional live Redis read for current month top features — degraded state if sync cron stale is acceptable (show `syncedAt`).
 ## Verification
 **Commands:**
 - `cd memento-note && npm run test:unit -- tests/unit/entitlements.test.ts` — expected: pass after async limit loader changes
 - `cd memento-note && npx tsc --noEmit` — expected: no type errors
 **Manual checks:**
 - ADMIN `/admin/billing`: edit a limit, save, verify `/api/usage/current` reflects new cap for a test user on that tier.
 - Non-admin GET to admin-billing server actions returns unauthorized.
 - Two rapid AI calls at quota−1: only one succeeds.

 ## Intent
 **Problem:** L'utilisateur veut que l'IA analyse sa note et propose des graphiques pertinents basés sur les données détectées. Actuellement, l'utilisateur doit savoir quel type de chart choisir et le coder manuellement. Il manque un flux "magique" où l'IA propose et l'utilisateur choisit.
 **Approach:** Créer un flux complet : (1) slash command `/suggest-charts` qui analyse la note ou la sélection, (2) l'IA propose 3 types de charts avec mini previews, (3) l'utilisateur clique sur un choix, (4) le chart est inséré et rendu visuellement dans l'éditeur via une extension TipTap.
 ## Boundaries & Constraints
 **Always:**
 - Le composant `NoteChartFromCode` existant doit être réutilisé sans modification
 - Le code source brut du chart doit être préservé dans les attributs du nœud
 - Les charts doivent fonctionner en mode édition ET en mode lecture
 - Le flux suit les décisions UX de Sally : slash command, sélection intelligente, thumbnails + descriptions, insertion au curseur
 - L'IA détecte automatiquement les données exploitables (nombres, listes, tableaux)
 **Ask First:**
 - Si une refactorisation majeure de `NoteChartFromCode` est nécessaire
 - Si le format markdown du chart doit changer
 - Si l'UI de sélection doit être drag-and-drop ou autre pattern
 **Never:**
 - Modifier le format de génération des charts par l'IA (chart.tool.ts)
 - Créer un nouveau composant de chart à côté de `NoteChartFromCode`
 - Implémenter un éditeur visuel de chart complex (le code reste la source de vérité)
 - Faire des suggestions automatiques intrusives (toujours déclenché par l'utilisateur)
 ## I/O & Edge-Case Matrix

 | LOADING_STATE | Commande slash activée | Animation "🔍 Analyse des données..." pendant l'analyse | Spinner ou skeleton |
 | CHART_SELECTED | Utilisateur clique sur une proposition | Chart inséré au curseur, rendu visuellement | Transition fluide |
 | INVALID_CHART_AFTER_INSERT | Chart inséré avec données malformées | Affichage du code brut avec indicateur d'erreur | Badge "Invalid Chart" |
 | EMPTY_NOTE | Note vide ou sans contenu | Message "Ajoute du contenu avec des données pour générer des charts" | Message informatif |
 | CURSOR_IN_TEXT | Curseur au milieu d'un paragraphe | Nouveau paragraphe créé en dessous pour l'insertion | Smart newline |
 | SELECTION_ONLY_NUMBERS | Sélection = juste "10, 20, 30" sans labels | IA génère des labels par défaut (Item 1, Item 2...) | Chart quand même fonctionnel |

 - Given les 3 propositions sont affichées, when l'utilisateur clique sur une, then le chart est inséré au curseur et rendu visuellement (pas comme code brut)
 - Given une note sans données exploitables, when l'utilisateur demande des suggestions, then un message friendly explique qu'aucune donnée n'a été détectée
 - Given un chart rendu visuellement, when l'utilisateur double-clique ou clique le bouton edit, then la vue bascule vers le code source pour édition
 - Given une note avec des charts, when elle est sauvegardée et rechargée, then tous les charts sont rendus correctement avec leurs données préservées
 - Given le curseur est au milieu d'un paragraphe, when un chart est inséré, then un nouveau paragraphe est créé en dessous pour éviter d'écraser le texte

 ### Structure du Modal de Suggestions
 ```typescript
 interface ChartSuggestion {
  type: 'bar' | 'line' | 'pie' | 'horizontal-bar' | 'area' | 'radar' | 'funnel' | 'gauge'
  title: string
  data: { label: string; value: number }[]
  description: string // "Bar chart: Comparaison des ventes par mois"
  rationale?: string // Pourquoi l'IA a choisi ce type
 }
 interface SuggestChartsResponse {
  suggestions: ChartSuggestion[3] // Exactement 3
  analyzedText: string // Ce qui a été analysé (pour feedback)
  detectedData: string // Description des données détectées
 }
 ```
 ### Format d'Insertion TipTap
 Le chart est inséré comme un code block avec language="chart" :
 ```html
 <pre><code class="language-chart">bar
 Ventes par Mois
 Jan: 5000
 Feb: 7500
 Mar: 6200</code></pre>
 ```
 L'extension TipTap détecte ensuite ce pattern et le rend visuellement avec NoteChartFromCode.
 ### Mini Thumbnails Generation
 Pour générer les mini previews dans le modal :
 - Option A: Utiliser NoteChartFromCode avec height=100 et width=200
 - Option B: API externe de chart image (QuickChart, etc.)
 - Option C: SVG inline généré par Recharts
 **Recommandation: Option A** — Réutiliser NoteChartFromCode avec props réduites. Plus simple et cohérent avec le rendu final.
 ### Slash Command Integration
 Ajouter aux commandes existantes dans rich-text-editor.tsx :
 ```typescript
 {
  title: 'Suggest Charts',
  description: 'AI suggère des graphiques basés sur votre contenu',
  icon: BarChart3,
  category: 'IA Note',
  isAi: true,
  command: (editor) => {
    openChartSuggestions(editor)
  }
 }
 ```
 ### Extension TipTap Structure (référence CustomImage)
 ```typescript
 export const ChartExtension = Node.create({
  name: 'chartBlock',
  group: 'block',
  code: true,
  parseHTML() {
    return [{
      tag: 'pre',
      getAttrs: node => {
        const codeEl = (node as HTMLElement).querySelector('code')
        return codeEl?.classList.contains('language-chart') ? {} : false
      }
    }]
  },
  renderHTML() {
    return ['pre', {}, ['code', { class: 'language-chart' }, 0]]
  },
  addNodeView() {
    return ReactNodeViewRenderer(ChartBlockView, {
      contentEditable: false,
    })
  }
 })
 ```
 ## Verification
 **Commands:**
 - `npm run build` -- expected: Build成功 sans erreurs TypeScript
 - `npm run lint` -- expected: Pas d'erreurs de linting dans les nouveaux fichiers
 - `npm run test` -- expected: Tests passent (si applicable)
 **Manual checks:**
 - Créer une note avec des données numériques, taper `/suggest-charts` → 3 propositions s'affichent
 - Sélectionner une partie de la note, taper `/suggest-charts` → Propositions basées sur la sélection
 - Cliquer sur une proposition → Chart inséré et rendu visuellement
 - Double-cliquer sur le chart → Vue code pour édition
 - Recharger la page → Charts toujours rendus correctement
 - Note vide → Message informatif "aucune donnée détectée"
 ## Suggested Review Order
 **Entry point: Slash command integration**
 - User triggers chart suggestions via `/suggest-charts` in menu

 <frozen-after-approval reason="human-owned intent — do not modify unless human renegotiates">
 ## Intent
 **Problem:** The home **Notes / Tasks** toggle only aggregates Markdown `- [ ]` / `- [x]` lines from `Note.content`. Rich-text TipTap task lists (HTML in `content`) and legacy `checklist` notes (`checkItems` JSON) are invisible in Tasks view, stats column, and sort-by-tasks — causing empty or misleading UX when users create to-dos via the editor or legacy data.
 **Approach:** Introduce a single extraction layer (`lib/tasks/`) that normalizes tasks from all three sources into a stable `UnifiedTask` model with source-specific stable IDs; update toggle/save paths to write back to the correct storage; refresh i18n to explain supported formats without Markdown-only wording.
 ## Boundaries & Constraints
 **Always:** No DB schema migration in v1 unless human approves; reuse existing `content` / `checkItems` fields; toggle must use optimistic `updateNote` + `onNotePatch`; all user-facing strings via i18n (EN+FR minimum); no new tests unless explicitly requested; do not conflate Structured Views `checkbox` properties with inline note tasks.
 **Ask First:** Deprecate vs revive `type: checklist` (dedicated note type); one-way migration of legacy `checkItems` → Markdown or TipTap; nested TipTap task support in aggregated view; scope of 15-locale fill vs EN/FR keys only.
 **Never:** Treat Structured View kanban/status as Tasks view; store a parallel tasks table; rewrite entire editor serialization to JSON; run destructive DB commands; claim done without manual verification on markdown + richtext + checklist sample notes.
 ## I/O & Edge-Case Matrix
 | Scenario | Input / State | Expected Output / Behavior | Error Handling |
 |----------|--------------|---------------------------|----------------|
 | Markdown tasks | `type: markdown`, content with `- [ ]` lines | Tasks listed; toggle flips `[ ]`↔`[x]` in content | Skip malformed lines |
 | TipTap tasks | `type: richtext`, HTML with `ul[data-type="taskList"]` | Tasks listed with text from `<p>` inside `li`; toggle updates `data-checked` + checkbox | Skip items without parseable text |
 | Checklist note | `type: checklist`, `checkItems: [{id,text,checked}]` | All items listed; toggle updates matching item by `id` | Normalize legacy `done` → `checked` on read |
 | Mixed note | Markdown lines + TipTap HTML in same richtext note | Both sources extracted (dedupe by normalized text optional v2) | No double-toggle same semantic item in v1 if ambiguous |
 | Empty scope | Notebook with no extractable tasks | Empty state with format-agnostic hint | No errors |
 | Toggle race | User toggles in Tasks while note open in editor | Last write wins or editor refresh via `emitNoteChange` | Log + refetch on mismatch |
 | API update | `PUT /api/notes` with `checkItems` | Same JSON.stringify behavior as server actions | Align API with actions in same PR |
 </frozen-after-approval>
 ## Code Map
 - `memento-note/components/notes-list-views.tsx` — current `extractTasksFromNotes`, `getNoteTasksStats`, `handleToggleTask`, Tasks UI
 - `memento-note/components/home-client.tsx` — Notes/Tasks toggle, passes notes into list views
 - `memento-note/lib/types.ts` — `CheckItem`, `NoteType`
 - `memento-note/lib/utils.ts` — `parseNote`, `checkItems` deserialization
 - `memento-note/components/rich-text-editor.tsx` — TipTap TaskList/TaskItem extensions
 - `memento-note/components/note-editor/note-editor-context.tsx` — save forces `checkItems: null`; dormant checklist handlers
 - `memento-note/components/note-checklist.tsx` — checklist UI (legacy card path)
 - `memento-note/components/note-card.tsx` — checklist toggle via `updateNote({ checkItems })`
 - `memento-note/app/actions/notes.ts` — canonical server update, JSON.stringify checkItems
 - `memento-note/app/api/notes/[id]/route.ts` — API checkItems inconsistency
 - `memento-note/locales/en.json`, `fr.json` — `notes.viewTasks`, `tasksEmptyHint`, etc.
 - `memento-note/lib/note-preview.ts` — excerpt may leak `[ ]` syntax
 ## Tasks & Acceptance
 **Execution (proposed — after study approval):**
 - [ ] `memento-note/lib/tasks/types.ts` — define `UnifiedTask`, `TaskSource`, stable `taskKey` — single contract for UI
 - [ ] `memento-note/lib/tasks/extract-tasks.ts` — extract from markdown lines, TipTap HTML (DOMParser or regex+guard), checkItems — replaces inline regex in list views
 - [ ] `memento-note/lib/tasks/toggle-task.ts` — source-aware write-back to content or checkItems — replaces fragile lineIndex-only toggle
 - [ ] `memento-note/components/notes-list-views.tsx` — wire extract/toggle helpers; show source badge optional — keep UI, fix data layer
 - [ ] `memento-note/locales/en.json`, `fr.json` — tasksEmptyHint, tasksHeader, optional `tasksSourceMarkdown` / `tasksSourceRichText` / `tasksSourceChecklist` — honest UX
 - [ ] `memento-note/app/api/notes/[id]/route.ts` — stringify checkItems like server actions — fix API drift
 **Acceptance Criteria:**
 - Given a markdown note with `- [ ] Buy milk`, when user opens Tasks view for that notebook, then the task appears and toggling persists after reload.
 - Given a richtext note with TipTap task list in saved HTML, when user opens Tasks view, then tasks appear with correct checked state.
 - Given a checklist note with `checkItems`, when user opens Tasks view, then items appear and toggle updates `checkItems` not content.
 - Given empty notebook, when user opens Tasks view, then empty state text does not mention Markdown-only format.
 - Given user toggles task in aggregated view, when note is reopened, then editor reflects the same checked state.
 ## Design Notes
 **Recommended architecture:** pure functions in `lib/tasks/` — no new DB columns. `UnifiedTask` fields: `taskKey`, `noteId`, `noteTitle`, `text`, `completed`, `source: 'markdown'|'tiptap'|'checklist'`, `locator` (lineIndex | domPath | checkItemId).
 **TipTap HTML (observed):** `ul[data-type="taskList"] > li[data-type="taskItem"][data-checked="true|false"]` with label+checkbox and content in nested `div > p`. Toggle: flip `data-checked`, sync `input:checked`, preserve HTML structure.
 **Checklist type decision:** AGENTS.md documents type as legacy/semi-dead. v1 should **read** existing `checkItems` in Tasks view; reviving full checklist editor is a separate story.
 **i18n:** Replace Markdown-only hint with product copy: tasks are collected from checkboxes in notes (lists in rich text, markdown, or checklist notes). Optional short “How it works” link/tooltip.
 **Out of scope v1:** Structured Views checkbox properties; cross-note deduplication; migrating all checklist notes to richtext; nested task hierarchy display.
 ## Verification
 **Commands:**
 - `cd memento-note && npm run lint` — expected: no new errors in touched files
 **Manual checks:**
 - Create 3 notes in one notebook: markdown with `- [ ]`, richtext with TipTap todo block, import/mock checklist with checkItems — all visible in Tasks view, each toggle survives refresh.

 <frozen-after-approval reason="human-owned intent — do not modify unless human renegotiates">
 ## Intent
 **Problem:** The current `/database` slash command inserts a self-contained "Authors & Works" relational block with hardcoded Jules Verne / Liu Cixin demo data stored as JSON blobs in TipTap node attributes — completely disconnected from Structured Views (NotebookSchema / NoteProperty), duplicating a data model and confusing users who expect a real notebook-linked view.
 **Approach:** Replace the current `databaseBlock` TipTap node and its three files (extension, editor component, types) with a new `structuredViewBlock` node that stores only a reference (`notebookId`, `displayMode`, `filter`), then reads live data from the existing Structured Views API — or falls back gracefully when the notebook has no schema.
 ## Boundaries & Constraints
 **Always:**
 - The block stores only a reference (`notebookId` + metadata attrs) — never serialises note rows/property values into TipTap HTML.
 - The editor must receive `notebookId` from its parent (`note-content-area.tsx`) for the block to resolve its schema.
 - i18n: all labels go through `useLanguage()` with keys in EN/FR minimum; no hardcoded strings.
 - Mutations (add note, edit property value) use optimistic updates via `NOTE_REQUEST_SAVE_EVENT` — no full revalidatePath.
 - If the current notebook has no `NotebookSchema`, show a contextual callout ("This notebook has no structured view — set one up from the notebook header") instead of a blank block; never auto-insert demo data.
 - Migration: silently drop legacy `databaseBlock` nodes on load (treat as unknown node, ProseMirror drops them or show an "outdated block" placeholder).
 - On delete of the block: only the TipTap reference node is removed; no Prisma records are affected.
 - RTL (fa, ar): the block wrapper must respect `dir="auto"`.
 **Ask First:**
 - Whether the block should support inline editing of property values (clicking a cell to edit) or be read-only with a "Open in notebook" CTA only — founder decides before coding begins.
 - Whether Kanban view is in scope for v1 inline (complex drag-and-drop inside a TipTap NodeView) or deferred to v2.
 **Never:**
 - Insert any demo data (no Jules Verne, no placeholders rows, no fake schema).
 - Create a second data storage system parallel to NotebookSchema/NoteProperty.
 - Store note rows or property values in TipTap node attributes.
 - Copy the `DatabaseBlockEditor` or `database-block-types.ts` pattern.
 - Use `revalidatePath` for mutations from inside the block.
 ## I/O & Edge-Case Matrix
 | Scenario | Input / State | Expected Output / Behavior | Error Handling |
 |----------|--------------|---------------------------|----------------|
 | Happy path — structured notebook | Note in structured notebook, user types `/vue` → insert block | Block renders table of notes with their schema properties | — |
 | No schema on notebook | Note is in a plain notebook (no NotebookSchema) | Block shows callout "Set up a structured view from the notebook header" with link | CTA links to notebook toolbar wizard |
 | Note not in any notebook | Note has no `notebookId` | Block shows "This block requires a notebook. Move this note to a notebook to use it." | Graceful inline message |
 | Legacy `databaseBlock` node found on load | HTML contains `data-database-block="true"` | ProseMirror skips the node (unknown type after extension removal); optionally show 1-line deprecation placeholder | No crash, no data loss on other content |
 | API error fetching schema | `GET /api/notebooks/:id/schema` 500 | Block shows error state with retry button | Console.error, no spinner freeze |
 | Inline edit (if in scope) — optimistic patch | User edits a cell → PATCH `/api/notes/:id/properties` | Optimistic update on cell, save triggered via NOTE_REQUEST_SAVE_EVENT | Rollback cell on API error |

 ## Code Map
 - `memento-note/components/tiptap-database-block-extension.tsx` -- **DELETE** — legacy authors/works TipTap node
 - `memento-note/components/database-block-editor.tsx` -- **DELETE** — legacy authors/works editor
 - `memento-note/lib/editor/database-block-types.ts` -- **DELETE** — legacy types with Verne/Cixin data
 - `memento-note/components/tiptap-structured-view-block-extension.tsx` -- **NEW** — TipTap Node extension (`structuredViewBlock`, attrs: `notebookId`, `displayMode: 'table'|'gallery'`, `filterJson`)
 - `memento-note/components/structured-view-block-embed.tsx` -- **NEW** — React NodeView component; fetches schema via SWR(`/api/notebooks/${notebookId}/schema`) and renders `NotesStructuredTable` or `NotesGalleryView` in read-only mode (or editable if founder approves inline edit)
 - `memento-note/components/note-editor/note-content-area.tsx` -- **MODIFY** — pass `notebookId={note.notebookId}` to `<RichTextEditor>`
 - `memento-note/components/rich-text-editor.tsx` -- **MODIFY** — accept `notebookId?: string` prop; pass it to editor storage; register `StructuredViewBlockExtension` in place of `DatabaseBlockExtension`; update slash command entry (label, keywords, handler); update block action menu's "Transform into" option
 - `memento-note/components/block-action-menu.tsx` -- **MODIFY** — replace `database` option with `structuredView`; import from new extension
 - `memento-note/locales/en.json` + `fr.json` -- **MODIFY** — add keys: `structuredViewBlock.insertLabel`, `structuredViewBlock.insertDesc`, `structuredViewBlock.noSchema`, `structuredViewBlock.noNotebook`, `structuredViewBlock.openInNotebook`, `structuredViewBlock.displayModeTable`, `structuredViewBlock.displayModeGallery`; remove all `databaseBlock.*` keys (after verifying no other consumer)
 ## Tasks & Acceptance
 **Execution:**
 - [ ] `memento-note/lib/editor/database-block-types.ts` -- DELETE file -- eliminates Verne/Cixin hardcoded data and legacy type definitions
 - [ ] `memento-note/components/database-block-editor.tsx` -- DELETE file -- removes authors/works editor UI
 - [ ] `memento-note/components/tiptap-database-block-extension.tsx` -- DELETE file -- removes legacy TipTap node extension
 - [ ] `memento-note/components/tiptap-structured-view-block-extension.tsx` -- CREATE — TipTap Node `structuredViewBlock` with attrs `{ notebookId: string, displayMode: 'table'|'gallery', filterJson: string }`, `ReactNodeViewRenderer(StructuredViewBlockEmbed)`
 - [ ] `memento-note/components/structured-view-block-embed.tsx` -- CREATE — NodeView wrapper: SWR fetch schema, conditional rendering (no-schema callout / no-notebook callout / table or gallery view), RTL-safe wrapper, `dir="auto"`
 - [ ] `memento-note/components/note-editor/note-content-area.tsx` -- MODIFY — add `notebookId={note.notebookId ?? undefined}` prop to both `<RichTextEditor>` instances
 - [ ] `memento-note/components/rich-text-editor.tsx` -- MODIFY — (a) add `notebookId?: string` to props, store in `editor.storage.structuredViewBlock = { notebookId }`; (b) swap `DatabaseBlockExtension` for `StructuredViewBlockExtension`; (c) update slash entry: title key `structuredViewBlock.insertLabel`, description key `structuredViewBlock.insertDesc`, keywords `['vue', 'tableau', 'structuré', 'structured', 'view', 'database', 'db']`; (d) update slash handler to call `insertStructuredViewBlockAtSelection(editor, notebookId)`
 - [ ] `memento-note/components/block-action-menu.tsx` -- MODIFY — replace `database` transform option with `structuredView`; update import
 - [ ] `memento-note/locales/en.json` + `fr.json` -- MODIFY — add new i18n keys (see Code Map); remove `databaseBlock.*` keys
 **Acceptance Criteria:**
 - Given a note in a structured notebook, when user types `/vue` or `/structured`, then a `structuredViewBlock` node is inserted showing the notebook's notes and their properties — no demo data appears.
 - Given the block is inserted, when the notebook has no schema, then the block shows a callout with a link to the notebook header wizard — no crash, no empty white box.
 - Given the note has no notebookId, when `/vue` is triggered, then the block shows an inline "requires a notebook" message.
 - Given a note with a legacy `data-database-block` node, when the note is opened, then the legacy block is silently dropped (or shown as deprecated placeholder) and the rest of the note content is intact.
 - Given the block is visible, when user resizes or the app language is Persian (fa, RTL), then the block layout is mirrored correctly.
 - Given the slash command menu opens, when user searches "database" or "db", then the new `structuredViewBlock` entry appears (backward-compatible keywords).
 - Given "Transform into" is opened in the block action menu, the "Database" option is replaced by "Vue structurée" / "Structured View".
 ## Spec Change Log
 ## Design Notes
 **Why reference-only attrs?** Storing note rows in TipTap HTML scales to O(notes × properties) per keystroke — unacceptable for perf. The reference pattern (`notebookId` only) is how Notion "linked database" blocks work and aligns with Memento's already-existing API layer.
 **notebookId propagation:** The editor currently receives only `noteId`. The smallest change is to add `notebookId` as a prop to `RichTextEditor` (already used by `note-content-area.tsx`). No context change needed.
 **Legacy migration:** ProseMirror silently drops unknown node types when the corresponding extension is not registered. Removing `DatabaseBlockExtension` from the extensions array is sufficient for new sessions. For existing notes with the old HTML, the `data-database-block` div will parse as an unrecognised block and ProseMirror will omit it. If this is too silent, add a `parseHTML` rule in the new extension that matches `div[data-database-block]` and converts it to a deprecated-placeholder paragraph.
 ## Verification
 **Commands:**
 - `npm run lint --prefix memento-note` -- expected: 0 errors (no imports from deleted files)
 - `npm run build --prefix memento-note` -- expected: build succeeds, no missing module errors
 **Manual checks (if no CLI):**
 - Open a note in a structured notebook → type `/vue` → confirm block appears with real notes (not Jules Verne).
 - Open a note in a plain notebook → type `/vue` → confirm "no schema" callout appears.
 - Open a note with a saved legacy `databaseBlock` → confirm note loads cleanly, no crash.
 - Switch app language to `fa` → confirm block layout is RTL-mirrored.
