+## Triage 2026-08-15
+- Symptôme: sur l'interface web PC, l'accès aux fichiers échoue avec `missing Origin header`.
+- Diagnostic convergent UX/Architect: rejet backend `403` sur validation `Origin` appliquée aux routes `/api/*`, y compris des `GET` fichiers browser-safe.
+- Branche locale créée par Git: `fix/214-web-origin-header-file-access` depuis `develop`.
+- Direction de fix: conserver le contrôle strict `Origin` pour `POST`/`OPTIONS`/WS, mais accepter les `GET` lecture/fichiers sans header `Origin` et ajouter des tests de non-régression.
+- UX: si un message utilisateur reste nécessaire, ne pas exposer le texte technique brut `missing Origin header`.
+
+## Implémentation DevBackend
+- Fichier modifié: `crates/web-server/src/lib.rs`.
+- Politique livrée: `GET /api/project-files`, `/api/project-files/download-file`, `/api/project-files/download-directory` acceptés sans `Origin`; validation stricte maintenue si `Origin` est présent.
+- Non-régression attendue: `POST /api/pair` sans `Origin` toujours refusé, WebSocket sans `Origin` toujours refusé.
+- Tests DevBackend:
+  - `cargo fmt --package web-server` => OK
+  - `cargo test -p web-server origin_header` => OK (3 tests)
+  - `cargo test -p web-server authorized_project_file_gets_allow_missing_origin_header` => OK
+  - `cargo test -p web-server` => KO (`Too many open files`)
+  - `cargo test -p web-server -- --test-threads=1` => échecs PTY/WebSocket non reliés au correctif Origin selon DevBackend
+
+## Verdict QA
+- QA a ajouté un test négatif complémentaire pour verrouiller qu'une route fichier non-GET sans `Origin` reste refusée.
+- Commande validante principale: `cargo test -p web-server origin_header -- --nocapture` => VERT (4/4)
+- Rejeu ciblé: `cargo test -p web-server non_get_project_file_route_still_requires_origin_header -- --nocapture` => VERT
+- Conclusion: `GET /api/project-files*` sans `Origin` accepté; `POST /api/pair`, WebSocket et route fichier non-GET sans `Origin` refusés.
