+# Chantier « fondations produit » — relecture, équipes, XLIFF (2026-08-29)
+
+> Décision de la session : **aucune intégration DeepL**. Tout ce qui suit est
+> 100 % moteur maison/LLM existants.
+
+## 1. Fondation : persistance des segments par job
+
+- **Modèle `TranslationSegment`** (`database/models.py`) : paires (source,
+  traduction) par job et par utilisateur, avec statut de relecture
+  (`pending | approved | edited`), texte relu, index, horodatages.
+- **Migration `f7e8d9c0b1a2`** (alembic) : `translation_segments`,
+  `workspaces`, `workspace_members`, `glossaries.workspace_id`. Appliquée et
+  vérifiée sur base vierge (chaîne complète 001→tête) et sur la base de dev.
+- **Capture** (`translators/segments.py`) : un `SegmentRecorder` est injecté
+  par la route dans les 4 traducteurs (docx/xlsx/pptx/pdf). Il enregistre
+  chaque paire unique dans l'ordre du document ; les paires identiques
+  (non traduites) sont ignorées pour garder la liste actionnable.
+- **Overrides** : `set_segment_overrides()` applique les traductions
+  **relues par l'humain** mot pour mot lors de la reconstruction — priorité
+  maximale (avant TM et provider), zéro appel API, zéro dérive.
+- **Persistance** : après un job réussi, la route stocke les segments en
+  base (best-effort, n'échoue jamais le job).
+
+## 2. API de relecture (`routes/review_routes.py`)
+
+| Endpoint | Rôle |
+|---|---|
+| `GET /api/v1/translations/{job_id}/segments` | Liste des segments + compteurs (accès propriétaire ou token du job) |
+| `PATCH /api/v1/segments/{id}` | Éditer (`reviewed_text` + `status=edited`) ou approuver — alimente aussi la TM par utilisateur (les traductions relues sont réutilisées dans les jobs suivants) |
+| `POST /api/v1/translations/{job_id}/rebuild` | Reconstruit le document avec les segments approuvés/modifiés (le texte relu est appliqué tel quel) puis pointe le téléchargement dessus |
+| `GET /api/v1/translations/{job_id}/xliff` | Export **XLIFF 1.2** (les segments modifiés exportent leur texte relu) |
+| `POST /api/v1/translations/{job_id}/xliff` | Import XLIFF : met à jour les segments (cible ≠ machine → `edited`, sinon `approved`) |
+
+Note UX : la reconstruction nécessite le fichier source encore présent
+(rétention 30 min). Au-delà, le messageInvite à re-téléverser — et les
+segments approuvés étant dans la TM, la nouvelle traduction les réutilise
+automatiquement.
+
+## 3. Éditeur de relecture (frontend)
+
+- **`/dashboard/reviews/[jobId]`** — tableau côte à côte Source |
+  Traduction, édition inline, badges de statut, approbation unitaire ou
+  « Tout approuver », **Reconstruire et télécharger** (blob authentifié),
+  export/import XLIFF. Libellés 13 locales.
+- **Lien « Relire et corriger la traduction »** sur l'écran de fin de
+  traduction (`TranslationComplete`).
+
+## 4. Espaces de travail équipes (`routes/workspace_routes.py`)
+
+- Modèles `Workspace` / `WorkspaceMember` (rôles `owner | admin | member`).
+- Endpoints : création (plan **Business** requis), liste (avec rôle,
+  sièges utilisés/limite), ajout de membre **par e-mail** avec
+  **application de la limite de sièges** du plan du propriétaire
+  (Business = 5, Enterprise illimité), retrait (owner impossible à retirer).
+- **Glossaires partagés** : `glossaries.workspace_id` — le contrôle d'accès
+  (`get_glossary_terms`, `validate_glossary_access`) accepte désormais le
+  propriétaire **et les membres du workspace**.
+- **Page `/dashboard/teams`** : création d'espace, liste des membres,
+  invitation (e-mail + rôle), retrait, compteur de sièges, gate Business.
+- Facturation multi-sièges : v1 = application de la limite de sièges du
+  plan. (La facturation au siège réel côté Stripe — subscription items —
+  reste un chantier facturation à part.)
+
+## 5. Tests & vérifications
+
+- Nouveaux tests (`tests/test_review_foundation.py`, 11) : recorder,
+  overrides, **capture→rebuild de bout en bout sur un vrai docx** (le texte
+  relu atterrit dans le fichier reconstruit, le reste reste machine),
+  structure XLIFF + échappement XML, sièges, CRUD workspace, glossaire
+  partagé (membre OK / extérieur refusé).
+- Suite backend complète : voir résultat final ci-dessous.
+- `tsc --noEmit` OK sur les deux frontends ; navigation « Équipe » (Pro+)
+  et lien « Relire » ajoutés.
+
+## 6. Non livré (justifié)
+
+- **IDML / DITA** : spécifications de formats complètes à part entière
+  (structure InDesign / arbres DITA) — nouveaux parseurs dédiés, à
+  chiffrer séparément.
+- **Facturation Stripe au siège** (mètre temps réel des sièges) : la
+  limite plan est appliquée ; le mètre Stripe nécessite des subscription
+  items et un webhooks sièges.
+- **Éditeur de relecture temps réel multi-utilisateur** (verrouillage de
+  segment, présence) : nécessite WebSocket + verrous — v1 = relecture
+  solo/équipe asynchrone.
