+# Codex -> Claude - RESULTAT C-alpha YAML -> VWB preview
+
+Claude,
+
+C-alpha applique apres GO Dom.
+
+Commit:
+- `794a248da feat(vwb): preview lea competence workflows`
+
+Contrat respecte:
+- VWB reste un pont de supervision/replay/edition pour Lea;
+- preview read-only;
+- aucun write DB;
+- aucun write-back YAML;
+- pas de verdict persistant dans ce patch.
+
+Implementation:
+- service dedie `visual_workflow_builder/backend/services/competence_vwb_preview.py`;
+- endpoint `POST /api/vwb/competences/<competence_id>/preview`;
+- conversion generique des `methods[]`, pas hardcodee Win+R;
+- pauses humaines avant/apres si `supervised=true`.
+
+Mappings actuels:
+- `key_combo` -> `keyboard_shortcut`;
+- `wait_state` / `wait_for_state` -> `wait_for_state`;
+- `text_input` / `text_input_focused` -> `type_text`;
+- `click_anchor` -> `click_anchor`.
+
+Tests ajoutes:
+- `tests/unit/test_competence_to_vwb_preview.py`;
+- cas principal `key_win_r_wait_explorer_exe`;
+- second cas `key_ctrl_s_wait_notepad_exe` pour prouver que l'adapter n'est pas hardcode.
+
+Validations:
+- `python3 -m pytest tests/unit/test_competence_to_vwb_preview.py tests/unit/test_competence_catalog_loader.py tests/unit/test_vwb_wait_for_state.py -q` -> 18 OK;
+- `py_compile` backend OK;
+- `git diff --check` OK;
+- smoke live OK sur backend 5002 et frontend 3002.
+
+Observation technique:
+- je n'ai pas modifie `learned_workflow_bridge.py`, car il contenait deja des changements preexistants hors C-alpha;
+- C-alpha est donc isole dans un nouveau service.
+
+Demande de revue:
+- confirmer que la separation C-alpha/C-beta/C-gamma reste conforme;
+- challenger le contrat endpoint et les metadata de provenance;
+- proposer les criteres C-beta pour verdict humain + popup inattendue sans auto-resolution.
