 # Changelog — FlowDeck

+## v4.10.0 (2026-09-05) — FlowDeck Agent : agent IA natif conversationnel
+
+> Implémentation complète du pilier « Agent IA » : un agent ReAct intégré qui **agit** sur le
+> workspace (pas seulement répond) — panneau de chat, boucle raisonnement→action, streaming SSE,
+> 18 outils avec snapshots rollback, permissions par rôle, contexte automatique, custom agents,
+> déclencheurs planifiés, skills réutilisables et multi-LLM (offline mock + 8 providers).
+
+### Added
+- **Interface conversationnelle** : panneau agent dans le sidebar (🤖 Agents) piloté par Alpine.js +
+  streaming SSE ; FAB ouvrant le chat ; historique de conversations.
+- **Boucle ReAct** (`app/services/agent_engine.py`) : raisonnement → action → observation, max 12
+  itérations, budget de tokens, timeout, journal d'audit + fonction `undo_action()` (rollback).
+- **Streaming SSE** : endpoint `/api/agent/conversations/{id}/run` qui émet `reasoning`, `action`
+  et `final` en temps réel.
+- **18 outils** (`app/services/tool_registry.py`) : `search_workspace`, `read_collection`,
+  `read_page`, `create_collection`, `create_view`, `add_property`, `create_page`, `update_page`,
+  `write_blocks`, `add_relation`, `create_sub_item`, `add_dependency`, `apply_template`,
+  `delete_page`, `delete_collection`, `read_gitea_issues`, `sync_gitea`, `create_gitea_issue` —
+  chacun avec `ToolResult` + snapshot d'undo réversible.
+- **Permissions** (`app/services/permission_manager.py`) : même ACL que l'utilisateur par rôle
+  workspace (viewer/editor/admin/owner) + gating des outils.
+- **Contexte automatique** (`app/services/context_builder.py`) : snapshot du workspace actif,
+  collections, pages, mentions `@`, fichiers uploadés injectés dans le prompt système.
+- **Multi-LLM** (`app/services/llm_client.py`) : OpenAI, Anthropic, Google, Ollama, DeepSeek,
+  QwenCloud, NVIDIA, OpenRouter + **offline mock** (planner déterministe, aucune clé requise).
+- **Custom agents, skills, déclencheurs** : CRUD agents + conversations, `agent_*` tables
+  (`agents`, `agent_conversations`, `agent_messages`, `agent_actions`, `agent_skills`,
+  `agent_triggers`), skills (`/api/agent/skills`, apply), scheduler de fond pour triggers planifiés.
+
+### Infra
+- `VERSION` → 4.10.0 ; config LLM (`LLM_PROVIDER/MODEL/API_KEY/API_BASE`, `AGENT_MAX_*`) ;
+  exclusions CSRF `/api/agent` ; routeur agent + tâche scheduler dans le lifespan de `app/main.py`.
+
+### Tests
+- **226 tests verts** (+18 v4.10.0 : schéma DB, mock LLM, permissions, outils+undo, engine ReAct +
+  audit + rollback, CRUD agents/conversations, streaming SSE, skills, tools, providers).

+## v5.10.0 — Éditeur : interactions de bloc ⬜ (non commencé)
+> **Objectif** : parité de manipulation des blocs avec Notion. Actuellement les blocs sont
+> éditables mais *statiques* : impossible de les déplacer, dupliquer ou annuler une action.
+
+- [ ] **Drag & drop des blocs** — poignée ⋮⋮ au survol de chaque bloc, drag vertical pour réordonner, indicateur de drop (ligne bleue), support multi-sélection de blocs (Shift+clic → déplacement groupé)
+- [ ] **Menu contextuel de bloc** — clic sur ⋮⋮ : Turn into (changer le type), Duplicate, Copy link to block, Move to, Delete, couleur de texte/fond
+- [ ] **Undo / Redo** — Ctrl+Z / Ctrl+Shift+Z ou Ctrl+Y sur l'état des blocs (pile d'opérations inversibles par page, conservée en mémoire du tab)
+- [ ] **Duplicate block** — Ctrl+D sur le bloc courant (copie insérée juste en dessous)
+- [ ] **Slash command étendue** — la commande `/` propose aussi : Turn into, Duplicate, et toutes les actions du menu bloc
+- [ ] **En-têtes de tableau (bloc table v4.8.0)** — toggles « First row as header » / « First column as header » dans la config du bloc table, rendu `<th>` correspondant en preview et exports
+
+## v5.11.0 — Wiki-links & mentions de page ⬜ (non commencé)
+> **Objectif** : le graphe de connaissances Notion. Complète les backlinks de v5.4.0
+> (section « Lié depuis ») par la création des liens depuis l'éditeur.
+
+- [ ] **Wiki-links `[[`** — taper `[[` ouvre un picker de pages (recherche fuzzy, toutes collections), Enter insère un lien interne rendu comme chip de page (icône + titre mis à jour dynamiquement)
+- [ ] **Mention de page `@`** — dans le menu @ existant (utilisateurs v4.9.0), ajouter l'onglet « Pages » : `@` suivi d'un nom de page crée un lien inline
+- [ ] **Mention de date `@`** — `@today`, `@tomorrow`, `@2026-10-01` rendus comme chips de date
+- [ ] **Renommage propagé** — renommer une page met à jour le libellé affiché de tous ses liens internes (résolution au rendu via `page_id`, pas de texte dur)
+
+## v5.12.0 — Templates & verrouillage de page ⬜ (non commencé)
+> **Objectif** : démarrage rapide productif et protection des pages stabilisées.
+> Les `page_templates` existent (v2.0.0/v4.2.0) mais uniquement côté collections.
+
+- [ ] **Template picker global** — sur « + New page » : galerie de templates (Empty, Meeting notes, Weekly report, To-do list…) + templates custom utilisateur
+- [ ] **Bouton « Use template »** — duplication du contenu du template dans la nouvelle page
+- [ ] **Page lock** — toggle 🔒 dans le menu « … » : page en lecture seule (édition désactivée pour tous sauf owner/admin), indicateur visuel en topbar
+- [ ] **Full-width mode** — toggle pour passer la page en pleine largeur (comme Notion)
+- [ ] **Small text / typo options** — option de page : taille de police réduite, serif/mono
+
+## v5.13.0 — Collaboration temps réel ⬜ (non commencé)
+> **Objectif** : avancer depuis v6.0.0 le chantier n°1 de la parité Notion en équipe.
+> Sans realtime, FlowDeck reste un outil mono-utilisateur partagé.
+
+- [ ] **WebSocket gateway** — endpoint `/ws/pages/{id}`, auth via session, rooms par page
+- [ ] **Présence** — avatars des utilisateurs connectés sur la page (topbar), couleur par utilisateur
+- [ ] **Curseurs live** — position des curseurs/sélections des autres éditeurs, label avec nom
+- [ ] **Merge de modifications** — diffusion des opérations de blocs (insert/update/delete/move) avec last-write-wins par bloc + version de page pour détecter les conflits
+- [ ] **Fallback polling** — si WS indisponible, rafraîchissement diff toutes les 10 s
+
+## v5.14.0 — Synced blocks ⬜ (non commencé)
+> **Objectif** : avancer depuis v6.0.0 un bloc Notion très utilisé (même contenu dans
+> plusieurs pages, édité une fois).
+
+- [ ] **Bloc `synced_block`** — table `synced_blocks` (source de vérité) + références par page ; slash command `/synced`
+- [ ] **Rendu** — ring rouge + badge « Synced » sur le bloc ; édition à un endroit => mise à jour partout (via rooms WS v5.13.0 si actives, sinon au reload)
+- [ ] **Unsync** — action « Unsync » qui convertit l'instance en copie indépendante
+- [ ] **Copy & sync across pages** — copier un bloc dans une autre page avec option « Paste and sync »

+"""FlowDeck — LLM client abstraction (v4.10.0).
+
+Abstraction over multiple LLM providers so the agent never talks to the DB
+directly — it emits *tool intentions* (function calls) that AgentEngine turns
+into guarded internal actions.
+
+Supported providers (OpenAI-compatible chat-completions JSON response):
+  openai, anthropic*, google*, deepseek, qwencloud, nvidia, openrouter, ollama.
+  (* routed through an OpenAI-compatible gateway / any configured api_base)
+
+When no API key is configured (or provider == "offline") the client falls back
+to a deterministic, dependency-free *mock planner*. This keeps the whole agent
+functional — and fully testable — with zero external calls, which is what the
+local deployment and the test-suite rely on.
