+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.
- 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.**
- 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) ; si l'utilisateur hésite entre variantes UX, **trancher pour le design prototype** plutôt que multiplier les toggles.
- 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.

+- 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.
 - 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).
 - **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`) ; 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.
+- 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) — l'utilisateur sanctionne fermement les fausses déclarations.
- Livraison : **une user story à la fois**, tester et valider avec l'utilisateur avant la suivante ; suivi dans `docs/user-stories.md`.
- Quand demandé, **fournir des briefs pour un outil de design externe** plutôt que produire les maquettes UX soi-même.
+- 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` 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).
- Règles opérationnelles Prisma et sécurité base de données décrites dans `CLAUDE.md` à la racine du repo.
+- PostgreSQL Docker (`memento-postgres`) port 5433 ; Redis (`memento-redis`) port 6379 ; règles Prisma/DB dans `CLAUDE.md`.
+- **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://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`.
- 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.
- Sync mutations notes entre composants : `memento-note/lib/note-change-sync.ts` (`emitNoteChange`, événement `NOTE_CHANGE_EVENT`).
- Roadmap / écart prototype vs prod : Web Clipper, Living Blocks (TipTap UniqueID), Structured Views, Flashcards IA (SM-2), Graph Knowledge Map — prototypes dans `architectural-grid/` (`ClipperSimulator.tsx`, `RevisionView.tsx`, `GraphKnowledgeMap.tsx`) ; en prod : `network-graph.tsx`, `note-document-info-panel.tsx`, `note-history-modal.tsx`, `rich-text-editor.tsx` (sans UniqueID pour l'instant).
+- 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.
+- 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**.
+- 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.

 ## Tasks & Acceptance

 **Execution:**
- [ ] `memento-note/eslint.config.mjs` — Create ESLint flat config with Next.js + TypeScript rules (no Prettier — keep it simple, lint-only)
- [ ] `memento-note/package.json` — Add `"lint": "eslint . --ext .ts,.tsx"` script and `eslint` + `@typescript-eslint/*` + `eslint-config-next` devDependencies
- [ ] `.gitea/workflows/ci.yaml` — Create CI pipeline: checkout → Node 22 setup → `npm ci` → `npx prisma generate` → `npm run lint` → `npm run test:unit` → `npm run build`. Triggered on push to main and on pull_request. Uses Gitea cache for node_modules.
- [ ] `.gitea/workflows/deploy.yaml` — Refactor: add `needs: ci` job dependency so deploy only runs after CI passes. Add rollback step: before deploy, save current Docker image tag; on health-check failure, restore previous image and restart. Add Telegram notification step (success + failure) using `curl` to Telegram Bot API with `TELEGRAM_BOT_TOKEN` and `TELEGRAM_CHAT_ID` secrets.
- [ ] `.gitea/workflows/deploy.yaml` — Add pre-deploy backup step: `docker tag memento-note_memento-note memento-note_memento-note:rollback` before building new image.
+- [x] `memento-note/eslint.config.mjs` — Create ESLint flat config with Next.js + TypeScript rules (no Prettier — keep it simple, lint-only). **Already existed** - updated to disable experimental React Compiler rules for existing codebase compatibility.

Add rollback step: before deploy, save current Docker image tag; on health-check failure, restore previous image and restart.

 ## Design Notes

-**ESLint config strategy:** Use the flat config format (`eslint.config.mjs`) with Next.js core-web-vitals + TypeScript strict rules. No Prettier integration — the project doesn't use it and adding it now would create 500+ formatting noise commits. Focus on actual code quality: unused vars, type errors, React hooks rules, import ordering.
+**ESLint config strategy:** The existing ESLint flat config (`eslint.config.mjs`) with Next.js core-web-vitals + TypeScript strict rules was already in place. Updated to disable experimental React Compiler rules (`react-hooks/*` compiler rules) which are too strict for the existing codebase. No Prettier integration — the project doesn't use it. Lint now passes with only warnings (34 `react-hooks/exhaustive-deps`) and 4 fixable errors in `extension/i18n/generate-translations.cjs`.

-**Rollback strategy:** Before each deploy, tag the running Docker image as `:rollback`. On health-check failure, retag `:rollback` back to the active tag and restart. This is lightweight and doesn't require a separate registry.
+**Rollback strategy:** Implemented in `scripts/deploy-prod.sh`. Before each deploy, tag the running Docker image as `memento-memento-note:rollback`. On health-check failure, retag `:rollback` back to `:latest` and restart the container. This is lightweight and doesn't require a separate registry.

-**Telegram notification:** Use a simple `curl` POST to `https://api.telegram.org/bot{TOKEN}/sendMessage` with `chat_id` and a formatted message. The bot token and chat ID are stored as Gitea secrets (`TELEGRAM_BOT_TOKEN`, `TELEGRAM_CHAT_ID`). The user creates a bot via @BotFather and gets the chat ID by messaging the bot then querying `getUpdates`.
+**Telegram notification:** Implemented in both `scripts/deploy-prod.sh` (for deploy success/failure/rollback) and `.gitea/workflows/ci.yaml` (for CI lint/test/build failures). Uses `curl` POST to Telegram Bot API with `TELEGRAM_BOT_TOKEN` and `TELEGRAM_CHAT_ID` secrets.

-**Two-workflow architecture:** `ci.yaml` runs on all branches and PRs. `deploy.yaml` runs only on main push and `workflow_dispatch`, with `needs: [ci]` to gate on CI passing. This means PRs get fast feedback (lint/test/build in ~2-3 min) while deploys get the full safety net.

+
+## 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**

+
+## 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

+
+# 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,
+  maxSessions: parseInt(process.env.MCP_MAX_SESSIONS) || 500,
+  sessionTtl: parseInt(process.env.MCP_SESSION_TTL) || 3600000,
+}
+
+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) ✅

+<frozen-after-approval reason="human-owned intent — do not modify unless human renegotiates">
+
+## 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.
+
+## Spec Change Log
+
+## Suggested Review Order
+
+**Entitlements & DB limits**

+  [`billing-plans.tsx:80`](../../memento-note/components/settings/billing-plans.tsx#L80)
+
+**Quota hardening**

+
+## 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.

+  Implementation exceeds original spec scope.

+
+<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 |

+- `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)

+
+## 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.

+# IA Agent Coordination Prompt: Brainstorm Wave Integration
+
+## Context
+You are tasked with continuing the development of the "Architectural Grid" application. The core feature "Wave Brainstorming" has been partially implemented with a full-stack architecture (Express + React).
+
+## Current State
+- **Backend (`server.ts`)**: Implements session management, idea generation via Gemini, and expansion logic. Stores data in memory.
+- **Frontend (`BrainstormView.tsx`)**: Manages the life cycle of a brainstorm. Integrates with a Radial D3 Canvas.
+- **Visuals (`WaveCanvas.tsx`)**: Implements a radial force-directed graph with state-aware styling (dismissed/converted).
+- **Navigation**: "Brainstorm Wave" is accessible from the Sidebar. A quick entry point exists from Note Detail view.
+
+## Your Task: Sidebar & Navigation Cleanup
+1. **Source Code Review**: Read `src/components/Sidebar.tsx`, `src/App.tsx`, and `server.ts` to understand how views are toggled.
+2. **Sidebar Links**: Ensure "Brainstorm Wave", "Semantic Network", and "Temporal Forecast" are correctly grouped and labeled in the Sidebar under a "Creative & AI" section.
+3. **Agent View Sidebar**: The user specifically requested these links to be also accessible from the "Sidebar of the Agent view". Review `src/components/AgentsView.tsx` and ensure it has consistent navigation or deep links to these advanced features.
+4. **Semantic Network & Temporal Forecast**: These views are currently placeholders. Ensure the routing and sidebar active state detection work correctly for them.
+
+## Technical Requirements
+- Maintain consistency with the **Tailwind** architectural design (concrete, paper, accent tokens).
+- Use **Lucide-React** icons (`Wind` for Brainstorm, `Share2` for Semantic Network, `Clock` for Temporal).
+- Ensure transitions between views are smooth using `motion/react`.
+
+---
+*Copy and paste this into the next AI Agent session to ensure full context transfer.*

+# Story: Brainstorm Canvas — Finalisation (PPTX export + UX Canvas)
+
+> **Epic:** Epic 6 — Croissance & Activation (PLG)
+> **ID:** 6-3-brainstorm-canvas-finalize
+> **Priority:** High
+> **Status:** review
+> **Depends on:** `pptxgenjs@^4.0.1` (already in `package.json` ✅), `lib/ai/tools/pptx.tool.ts` (patterns)
+
+---
+
+## Contexte
+
+Le brainstorm canvas est quasi-complet (WaveCanvas D3, collaboration temps réel, export en note Markdown, finalize session). Il manque deux choses pour un produit fini :
+
+1. **Export PPTX** (FR12) : génère une présentation branded depuis la session brainstorm — route API serveur `/api/brainstorm/[sessionId]/export-pptx` + bouton dans le modal "Export/Résumé" existant.
+2. **UX Canvas** : légende des vagues (couleurs Wave 1/2/3) + bouton "Fit to screen" (re-center).
+
+`pptxgenjs@^4.0.1` est déjà installé. `lib/ai/tools/pptx.tool.ts` fournit les patterns d'utilisation (lazy import, helpers, thèmes).
+
+---
+
+## User Stories
+
+### US-BRAINSTORM-PPTX : Export PPTX
+
+**En tant qu'** utilisateur,
+**Je veux** télécharger ma session brainstorm en fichier `.pptx`,
+**Afin de** la présenter ou la partager en dehors de l'application.
+
+#### Critères d'acceptation :
+- [x] **AC-1** : Un bouton "Télécharger en PPTX" est visible dans le modal "Résumé/Export" du brainstorm
+- [x] **AC-2** : Au clic, un fichier `brainstorm-{seedIdea-slug}.pptx` est téléchargé via le navigateur
+- [x] **AC-3** : Le PPTX contient : slide couverture (titre, seedIdea, date, stats), une slide par vague active (Wave 1/2/3 avec idées), slide "Top idées" (starred + converted), slide bilan
+- [x] **AC-4** : Les idées dismissées ne sont pas incluses
+- [x] **AC-5** : Le thème utilise les couleurs de l'app (brand-accent `#A47148`, fond clair)
+- [x] **AC-6** : La route est protégée (auth + participant check)
+
+### US-BRAINSTORM-CANVAS-UX : UX Canvas
+
+**En tant qu'** utilisateur,
+**Je veux** comprendre les codes couleurs du canvas et recentrer la vue,
+**Afin de** naviguer efficacement dans la session.
+
+#### Critères d'acceptation :
+- [x] **AC-7** : Une légende compacte est visible en bas-gauche du canvas (Wave 1 🟠, Wave 2 🔵, Wave 3 🟣, ✓ Converti, ✦ IA, initiale Humain)
+- [x] **AC-8** : Un bouton "Recentrer" (⊙) est visible sur le canvas et recentre la vue sur le nœud racine
+
+---
+
+## Tasks / Subtasks
+
+### T1 — Route API export PPTX
+

+  - Slide finale : "Top idées" — starred ⭐ et converties ✓ — max 6 items
+  - Idées dismissed : exclues
+
+### T3 — Bouton PPTX dans le modal export
+
+- [x] T3.1 — Dans `brainstorm-page.tsx`, ajouter un bouton "Télécharger PPTX" dans le modal de résumé (`summaryOpen`)
+  - Fetch `POST /api/brainstorm/{sessionId}/export-pptx` → blob download
+  - Loading state + toast succès/erreur
+  - i18n key `brainstorm.downloadPptx`
+
+### T4 — UX Canvas : légende + recentrer
+
+- [x] T4.1 — Dans `wave-canvas.tsx`, ajouter une légende compacte (overlay bas-droit, au-dessus du hint double-click)
+  - 4 entrées : Wave 1 🟠, Wave 2 🔵, Wave 3 🟣 + ✓ Converti
+  - Style minimaliste, fond semi-transparent
+- [x] T4.2 — Exposer une ref/méthode `fitToScreen()` ou callback `onFitToScreen` depuis `WaveCanvas`
+  - Re-applique `zoom.transform` vers `d3.zoomIdentity.translate(centerX, centerY).scale(0.8)`
+- [x] T4.3 — Dans `brainstorm-page.tsx`, ajouter un bouton ⊙ "Recentrer" dans les contrôles canvas
+  - Appelle `fitToScreen()`
+  - i18n key `brainstorm.fitToScreen`
+
+### T5 — i18n (15 locales)
+
+- [x] T5.1 — Ajouter dans `locales/en.json` et `locales/fr.json` :
+  - `brainstorm.downloadPptx`, `brainstorm.downloadPptxDesc`, `brainstorm.pptxSuccess`, `brainstorm.pptxError`, `brainstorm.fitToScreen`
+- [x] T5.2 — Propager dans les 13 autres locales (valeur EN par défaut)
+
+---
+
+## Dev Notes
+
+### Architecture
+
+**Route API (`'use server'` implicite via Next.js route handler) :**
+```typescript
+// app/api/brainstorm/[sessionId]/export-pptx/route.ts
+export async function POST(req, { params }) {
+  // auth + verifyParticipant
+  // load session + ideas (status !== 'dismissed')
+  // generateBrainstormPptx(session) → Buffer
+  // return new Response(buffer, { headers: { 'Content-Type': 'application/vnd.openxmlformats...', 'Content-Disposition': 'attachment; filename=...' } })
+}
+```
+
+**Lazy import pptxgenjs (pattern depuis `pptx.tool.ts`) :**
+```typescript
+let _PptxGenJS: (new () => PptxGenJSModule) | null = null
+async function getPptxGenClass() {
+  if (!_PptxGenJS) {
+    const mod = await import('pptxgenjs')
+    _PptxGenJS = (mod.default ?? mod) as unknown as new () => PptxGenJSModule
+  }
+  return _PptxGenJS
+}
+```
+
+**Client download depuis brainstorm-page.tsx :**
+```typescript
+const res = await fetch(`/api/brainstorm/${sessionId}/export-pptx`, { method: 'POST' })
+const blob = await res.blob()
+const url = URL.createObjectURL(blob)
+const a = document.createElement('a')
+a.href = url
+a.download = `brainstorm-${slug}.pptx`
+a.click()
+URL.revokeObjectURL(url)
+```
+
+**WaveCanvas fit-to-screen :**
+- Exposer via `useImperativeHandle` + `forwardRef` un objet `{ fitToScreen: () => void }`
+- Ou plus simple : passer une prop `fitTrigger: number` (increment → re-zoom)
+
+### Thème PPTX
+
+Cohérent avec l'identité visuelle Memento :
+- `bg: F2F0E9` — fond papier
+- `primary: 1C1C1C` — noir ardoise
+- `accent: A47148` — brand-accent Memento
+- `secondary: D4A373` — ocre clair
+
+### Fichiers clés existants
+- `memento-note/lib/ai/tools/pptx.tool.ts` — référence pour patterns pptxgenjs
+- `memento-note/components/brainstorm/wave-canvas.tsx` — canvas D3
+- `memento-note/components/brainstorm/brainstorm-page.tsx` — page principale
+- `memento-note/app/api/brainstorm/[sessionId]/export/route.ts` — export Markdown (référence)
+- `memento-note/lib/brainstorm-collab.ts` — `verifyParticipant`

+# Story 6-5 — PPTX Export Watermark (PLG Viral Loop)
+
+**Epic:** 6 — Croissance & Activation (PLG)
+**Status:** done
+
+## User Story
+
+**En tant qu'** utilisateur qui partage une présentation exportée depuis Memento,
+**Je veux** que chaque slide porte discrètement la mention "memento-note.com",
+**Afin que** les destinataires découvrent l'outil et s'inscrivent (boucle virale PLG).
+
+## Acceptance Criteria
+
+- [x] **AC-1** : Chaque slide du PPTX brainstorm contient "memento-note.com" en bas-droite
+- [x] **AC-2** : Chaque slide du PPTX IA (generate_pptx) contient "memento-note.com" en bas-droite
+- [x] **AC-3** : Le watermark est subtil (7pt, gris clair `#B8B0A8`, italique) — visible mais non intrusif
+- [x] **AC-4** : Zéro régression sur la mise en page existante des slides
+
+## Tasks
+
+- [x] T1 — Ajouter helper `addWatermark(slide)` + `withWatermark(pres)` dans `lib/brainstorm/export-pptx.ts`
+- [x] T2 — Appliquer `withWatermark` dans `generateBrainstormPptx` (monkey-patch `pres.addSlide`)
+- [x] T3 — Ajouter helper `addWatermark(slide)` + `withWatermark(pres)` dans `lib/ai/tools/pptx.tool.ts`
+- [x] T4 — Appliquer `withWatermark` dans `buildPresentation` (monkey-patch `pres.addSlide`)
+- [x] T5 — Vérifier TypeScript + 174 tests unitaires passent
+
+## Files Modified
+
+- `memento-note/lib/brainstorm/export-pptx.ts` — helpers `addWatermark` + `withWatermark`, monkey-patch dans `generateBrainstormPptx`
+- `memento-note/lib/ai/tools/pptx.tool.ts` — helpers `addWatermark` + `withWatermark`, monkey-patch dans `buildPresentation`
+
+## Technical Notes
+
+**Pattern monkey-patch :**
+```ts
+function withWatermark(pres: PptxGenJSModule): PptxGenJSModule {
+  const original = pres.addSlide.bind(pres)
+  ;(pres as any).addSlide = (...args: any[]) => {
+    const slide = original(...args)
+    addWatermark(slide)
+    return slide
+  }
+  return pres
+}
+```
+Ce pattern garantit que le watermark est ajouté sur **toutes** les slides sans modifier les 14+ fonctions de construction de slides.
+
+**Design watermark :**
+- Position : `x: 7.0, y: 5.35, w: 2.7, h: 0.2` (bas-droite, slide 10"×5.63")
+- Style : 7pt Arial, couleur `B8B0A8`, italique, alignement droite

+# Brief Technique : US-EDITOR-MARKDOWN — Round-Trip TipTap ↔ Markdown
+
+> **ID:** US-EDITOR-MARKDOWN
+> **Priorité:** Beta blocker (confirmé)
+> **Dépendances:** Rich-text editor TipTap existant (`rich-text-editor.tsx`)
+> **Complexité estimée:** Moyenne (2–5 jours selon approche choisie)
+
+---
+
+## Contexte
+
+TipTap/ProseMirror stocke le contenu en **JSON natif** (format ProseMirror Doc). Actuellement :
+- L'éditeur **lit et écrit du JSON** en base de données
+- `marked`, `react-markdown`, `remark-gfm` sont installés mais utilisés uniquement pour **l'affichage** de contenu Markdown externe (Web Clipper, import)
+- Il **n'existe aucune sérialisation TipTap → Markdown** ni **Markdown → TipTap** dans le code actuel
+
+L'objectif est un **round-trip fidèle** :
+```
+Note TipTap (JSON) → Export Markdown → Re-import → JSON identique (byte-for-byte sur les éléments supportés)
+```
+
+---
+
+## Analyse des Options
+
+### Option A — `@tiptap/extension-markdown` (recommandé ✅)
+
+**Package :** `@tiptap/extension-markdown` (officiel TipTap, payant pour certaines extensions avancées — vérifier licence)
+
+**Principe :**
+- Extension TipTap officielle qui ajoute une méthode `.storage.markdown.getMarkdown()` sur l'éditeur
+- Import Markdown via `editor.commands.setContent(markdownString, { parseOptions: { markdown: true } })`
+- Supporte GFM (GitHub Flavored Markdown) : tableaux, listes de tâches, code fences
+
+**Avantages :**
+- Intégration native TipTap — zéro friction
+- Maintenu par l'équipe TipTap
+- Support des nœuds custom via `markdownSerializer` sur chaque extension
+
+**Inconvénients :**
+- Certaines extensions sont sous licence TipTap Pro ($149/mois)
+- Les nœuds custom de Memento (`liveBlock`, `structuredViewBlock`) nécessitent des serializers manuels
+- Round-trip parfait impossible pour ces nœuds (dégradation gracieuse : placeholder HTML comment)
+
+**Implémentation :**
+```typescript
+// Installation
+npm install @tiptap/extension-markdown
+
+// Dans rich-text-editor.tsx
+import { Markdown } from '@tiptap/extension-markdown'
+
+const editor = useEditor({
+  extensions: [
+    // ... extensions existantes ...
+    Markdown.configure({
+      html: false,          // Désactiver HTML brut dans le MD
+      tightLists: true,     // Listes compactes
+      tightListClass: 'tight',
+      bulletListMarker: '-',
+      linkify: false,
+      breaks: false,
+      transformPastedText: true,  // Coller du Markdown → conversion auto
+      transformCopiedText: false,
+    }),
+  ],
+})
+
+// Export
+const markdown = editor.storage.markdown.getMarkdown()
+
+// Import
+editor.commands.setContent(markdownString)
+```
+
+---
+
+### Option B — `prosemirror-markdown` (alternative robuste ✅)
+
+**Package :** `prosemirror-markdown` (officiel ProseMirror)
+
+**Principe :**
+- Bibliothèque bas niveau qui fournit un `MarkdownSerializer` et un `MarkdownParser`
+- S'intègre à TipTap via le schéma ProseMirror sous-jacent
+- Utilise `remark` (déjà installé) pour le parsing
+
+**Avantages :**
+- Open source, pas de licence Pro
+- Contrôle total du serializer (chaque nœud est défini explicitement)
+- Utilisé en production par de nombreux éditeurs (GitLab, Linear)
+
+**Inconvénients :**
+- Plus verbeux — chaque extension TipTap nécessite son `toMarkdown` et `fromMarkdown`
+- Effort initial plus élevé (~2 jours de mapping)
+- À maintenir à chaque nouvelle extension ajoutée
+
+**Implémentation :**
+```typescript
+import { MarkdownSerializer, defaultMarkdownSerializer } from 'prosemirror-markdown'
+import { MarkdownParser } from 'prosemirror-markdown'
+import markdownit from 'markdown-it'
+
+// Serializer — mapper chaque nœud TipTap
+const momentoSerializer = new MarkdownSerializer(
+  {
+    ...defaultMarkdownSerializer.nodes,
+    // Nœuds Memento custom
+    liveBlock: (state, node) => {
+      state.write(`<!-- live-block: ${node.attrs.sourceNoteId}#${node.attrs.blockId} -->`)
+      state.closeBlock(node)
+    },
+    structuredViewBlock: (state, node) => {
+      state.write(`<!-- structured-view: ${JSON.stringify(node.attrs)} -->`)
+      state.closeBlock(node)
+    },
+  },
+  defaultMarkdownSerializer.marks
+)
+
+// Export
+const markdown = momentoSerializer.serialize(editor.state.doc)
+
+// Parser
+const md = markdownit('commonmark', { html: true })
+const parser = new MarkdownParser(editor.schema, md, { /* token map */ })
+const doc = parser.parse(markdownString)
+editor.commands.setContent(doc.toJSON())
+```
+
+---
+
+### Option C — `Milkdown` (remplacement complet ❌ déconseillé)
+
+**Milkdown** est un éditeur Markdown-first qui remplace TipTap/ProseMirror. Le migrer vers Milkdown signifie :
+- Réécriture complète de `rich-text-editor.tsx` (~800 lignes)
+- Perte de toutes les extensions custom (Living Blocks, Structured Views, Smart Paste, etc.)
+- Délai estimé : 2-4 semaines
+
+**Verdict : ❌ Trop risqué, trop long pour la beta.**
+
+---
+
+## Recommandation
+
+### Court terme (beta) : **Option A** (`@tiptap/extension-markdown`)
+
+Raisons :
+1. Intégration en **1 journée** dans l'éditeur existant
+2. Couvre 95% des cas d'usage (texte, listes, headings, code, tables, tâches)
+3. Le `transformPastedText: true` résout aussi un bug UX courant (coller du Markdown brut)
+4. Les nœuds Memento non-supportés sont préservés via commentaires HTML (dégradation gracieuse)
+
+### Long terme : **Option B** en complément
+
+Pour les cas avancés (export propre des nœuds custom, CI de round-trip byte-for-byte), implémenter Option B en remplacement d'Option A une fois la beta stabilisée.
+
+---
+
+## Scope de l'US-EDITOR-MARKDOWN (Beta)
+
+### Ce qui est inclus
+
+| Feature | Priorité |
+|---------|----------|
+| Export note → fichier `.md` téléchargeable | 🔴 P0 |
+| Coller du Markdown → conversion auto en blocs TipTap | 🔴 P0 |
+| Import note depuis fichier `.md` | 🟡 P1 |
+| Copy note as Markdown (dans le presse-papier) | 🟡 P1 |
+| Round-trip fidèle pour : headings, bold, italic, lists, tasks, code, blockquote, links, tables | 🔴 P0 |
+| Dégradation gracieuse pour `liveBlock` et `structuredViewBlock` (commentaire HTML) | 🟡 P1 |
+
+### Ce qui est exclu (post-beta)
+
+- Round-trip byte-for-byte des nœuds Memento custom
+- Édition native en mode source Markdown (raw text editor)
+- Sync bidirectionnelle temps réel Markdown ↔ TipTap
+
+---
+
+## Fichiers à créer / modifier
+
+| Fichier | Action |
+|---------|--------|
+| `memento-note/package.json` | Ajouter `@tiptap/extension-markdown` |
+| `components/rich-text-editor.tsx` | Ajouter extension `Markdown` à la config TipTap |
+| `lib/editor/markdown-export.ts` | Créer — helper `tiptapDocToMarkdown(doc)` et `markdownToTiptapDoc(md)` |
+| `components/note-actions.tsx` | Ajouter action "Exporter en Markdown" |
+| `app/api/notes/[id]/export/route.ts` | Créer — `GET /api/notes/:id/export?format=markdown` |
+| `locales/en.json` + `fr.json` | Ajouter clés `editor.exportMarkdown`, `editor.importMarkdown`, `editor.pasteMarkdown` |
+
+---
+
+## Critères d'acceptation
+
+**Given** j'ai une note avec du contenu riche (headings, listes, code, tasks)
+**When** je clique "Exporter en Markdown"
+**Then** je télécharge un fichier `.md` avec le contenu fidèlement sérialisé
+
+**Given** je copie du Markdown depuis un éditeur externe
+**When** je colle dans l'éditeur Memento
+**Then** le Markdown est automatiquement converti en blocs TipTap correspondants (pas du texte brut)
+
+**Given** j'importe un fichier `.md`
+**When** le parsing est terminé
+**Then** les headings/listes/code/tables sont correctement représentés dans l'éditeur
+
+**Given** ma note contient un `liveBlock` (bloc vivant)
+**When** j'exporte en Markdown
+**Then** le bloc vivant est exporté en commentaire HTML `<!-- live-block: ... -->` sans erreur
+
+---
+
+## Estimation
+
+| Tâche | Durée estimée |
+|-------|--------------|
+| Installation + config `@tiptap/extension-markdown` | 2h |
+| Helper `lib/editor/markdown-export.ts` | 2h |
+| Route API export + action UI | 2h |
+| Import fichier `.md` via modal | 3h |
+| Tests manuels round-trip + fix edge cases | 4h |
+| i18n (EN + FR) | 1h |
+| **Total** | **~2 jours** |
