fix: A25 + A21 (partiel) — plus d'exception muque, transaction protégée (v7.3.8)

- A25 — 84 `except Exception: pass/…` → `logger.exception("<fonction>")`
  (19 fichiers : api_v2 30, dashboard 10, board 7, sites 5, workspace 5,
  api_v2_helpers 5, …) ; `logger` ajouté là où il manquait (api_v2_helpers,
  sites + `import logging`)
- A25 critique — les `try` autour de `materialize_properties` supprimés dans
  `create_collection_v2` ET `apply_db_template_v2` : un échec interrompt la
  transaction au lieu de commiter une collection sans schéma
- test `test_collection_rollback_when_materialize_fails` (Bearer v2, monkeypatch
  qui lève, assertions : RuntimeError + 0 ligne commitée)
- A21 partiel — `PRAGMA busy_timeout=5000` dans `get_conn()` (point d'entrée
  unique) ; commentaire `ponytail:` : le wrapper async + les 510 call sites
  restent à migrer module par module
- suite **1028/1028** · `ruff check app tests` OK

 # Changelog - FlowDeck
 
+## v7.3.8 (2026-10-01) — Audit : A25 (exceptions muettes) + A21 partiel
+
+### Fixed
+
+- **A25** — 84 `except Exception: pass/…` deviennent `logger.exception(fn)`
+  (19 fichiers, 63 dans des handlers `async`) : les échecs du pipeline
+  d'événements/webhooks et des écritures sont enfin visibles dans les logs
+- **A25 (critique)** — plus de `try` autour de `materialize_properties` dans
+  `create_collection_v2` et `apply_db_template_v2` : un échec annule la
+  transaction au lieu de commiter une collection sans schéma
+- **A21 (partiel)** — `PRAGMA busy_timeout=5000` dans `get_conn()` (le seul
+  point d'entrée des connexions) ; le wrapper async + les 510 call sites
+  synchrones sur l'event loop restent à migrer
+

 - [x] **A18 — Collection publiée quelconque + stocké XSS** : `GET /workspace/public/{collection_id}` (`workspace.py:699-719`) « no auth required », **ignore les flags `restricted/private`**, et interpole `coll['name']`/`p['title']` dans un `HTMLResponse(f"""…""")` sans `html.escape`. *Fix : respecter les flags de partage + `html.escape`. Effort : **S**.*
 - [x] **A19 — Liste CSRF trop large (34 préfixes) — TERMINÉ 2026-09-30 : 17 préfixes retirés, aucun préfixe cookie-auth n'est plus exempté** (12 en v7.3.5 après scan + 5 en v7.3.6 après équipement des 46 call sites) (`/db/`, `/workspace`, `/workspace/automations`, `/board/api/favorites`, `/api/pages`, `/api/recents`, `/api/notifications`, `/api/comments`, `/api/automations`, `/api/github`, `/api/admin`, `/api/onboarding`) puis les 5 derniers en v7.3.6 (46 call sites équipés de `X-CSRF-Token` dans agent_panel, settings, local_workspace, library, gitea_workspace, workspace, workspaces, welcome) — il ne reste que du Bearer/callback/public/infra : `csrf.py:21,25` couvre `/api/v2`, `/api/admin`, `/db/`, `/workspace`, `/api/user`, `/api/settings`, `/board/api/pages`, `/api/local-workspace`, `/api/comments`, `/api/agent`, `/api/automations`, `/auth/2fa` — tous **cookie-auth**. Seul `/scim/v2` est justifié par le commentaire de la ligne 19-20. Bonus : `/api/workspace` exempt aussi `/api/workspaces/*`. Filet restant = `SameSite=Lax` par défaut (jamais déclaré explicitement dans `main.py:150`). *Fix : garder un petit ensemble SAFE (webhooks, `/api/v1`, `/api/v2` Bearer, `/scim/v2`, callbacks OAuth/SSO) + ancrer les préfixes ; ajouter le header sur les 49 `fetch()` concernés (helper `csrfFetch` existe déjà : `base.html:892`). Effort : **M**.*
 - [ ] **A20 — CSP sans filet : `script-src 'unsafe-inline' 'unsafe-eval'`** (`security.py:67`) → aucun nonce/hash ; combiné à A10, chaque sink XSS ci-dessus tourne sans violation CSP. *Fix : externaliser le JS inline (A27), passer à `'nonce-…'`, retirer `'unsafe-eval'` (Alpine/HTMX n'en ont pas besoin par défaut), resserrer `img-src`/`connect-src`. Effort : **L**.*
-- [ ] **A21 — `sqlite3` synchrone sur l'event loop** : `get_conn()` (`db.py:833-843`) est synchrone et **510 des 689 `async def` de routes** l'appellent (805 occurrences au total ; 0 `run_in_threadpool`, 1 seul `asyncio.to_thread` dans tout le dépôt : `semantic_search.py:262`) ; connexion neuve par requête (`connect` + 2 PRAGMA), **aucun `busy_timeout`**. Chaque requête bloque la boucle. *Fix : wrapper async (`anyio.to_thread.run_sync`) partagé, migrer d'abord `api_v2`/`dashboard`/`collections`/`board` + `PRAGMA busy_timeout=5000`. Effort : **M**.*
+- [ ] **A21 — `sqlite3` synchrone sur l'event loop — PARTIEL 2026-10-01 : `PRAGMA busy_timeout=5000` ajouté au point d'entrée unique `get_conn()` (db.py)** ; reste le wrapper async `anyio.to_thread` + la migration des 510 call sites : `get_conn()` (`db.py:833-843`) est synchrone et **510 des 689 `async def` de routes** l'appellent (805 occurrences au total ; 0 `run_in_threadpool`, 1 seul `asyncio.to_thread` dans tout le dépôt : `semantic_search.py:262`) ; connexion neuve par requête (`connect` + 2 PRAGMA), **aucun `busy_timeout`**.

 - [x] **A22 — Validateur d'upload = code mort** : `validate_upload()` + `ALLOWED_EXTENSIONS` + `MAX_UPLOAD_SIZE` (`security.py:33-40`) n'ont **aucun appelant** ; `upload_local_workspace_file` (`dashboard.py:1507-1574`) fait `file_path.write_bytes(content)` après seulement `Path(filename).name` — ni taille, ni extension, ni auth, et `/api/local-workspace` est exclu du CSRF. Chemin aussi codé en dur `Path(f"/data/uploads/...")` au lieu de `FLOWDECK_DATA_DIR`. *Fix : appeler `validate_upload()` avant `read()` + session. Effort : **S**.*
 - [x] **A23 — N+1 avérés** : `dashboard.py:905` (`COUNT(*) FROM pages` par page dans une boucle de 20), `board.py:2141-2146` (INSERT + `_extract_ai_keywords` par issue), `collections.py:378` (INSERT par propriété en boucle). *Fix : une agrégation `GROUP BY` / un `executemany`. Effort : **S**.*
 - [x] **A24 — 2 routes silencieusement mortes (vérifié en servant l'app)** : `GET /workspace` → `dashboard.py:820` (HTML, inclus 1er, `main.py:158`) écrase `workspace.py:30` **et** `library.py:537` (JSON, inclus après) ; `GET /api/projects` → `projects.py:24` (inclus 161) écrase `api.py:82` (handler Gitea). *Fix : supprimer/renommer les doublons + assertion au boot « pas deux routes même méthode+chemin ». Effort : **XS**.*
-- [ ] **A25 — 92 `except Exception: pass` dont 68 dans des handlers async, 0 loggé** (471 `except Exception` au total, 102 dans `api_v2.py` seul) ; pire : `api_v2.py:504-511` avale l'échec de `materialize_properties` **dans la transaction de création de collection** (collection commitée sans schéma), `api_v2.py:859`, et tous les `await _fire_event(...)` (`1750`, `885`, `903`) → pipeline d'événements/webhooks cassé = invisible. *Fix : `logger.exception` sur les 68 sites ; supprimer le try autour des 2 writes de `create_collection_v2`.
