+4cf0408 fix(acadenice): resolve test suite failures across R3 sub-blocks (Patch 017)
+         - 17 server specs converted from vitest to Jest (vi -> jest globals)
+         - jest.mock stubs for ESM-only prosemirror/html and collaboration modules
+         - Zod v4 strict UUID fixtures fixed (version byte [1-8][89abAB] required)
+         - JwtAuthGuard.overrideGuard added to all controller specs
+         - jest.Mock explicit types to prevent 'never' arg inference
+         - Client: deleted vitest.config.ts (CJS), kept vitest.config.mts (ESM)
+         - Client: global mocks for @excalidraw/excalidraw and @/main.tsx
+         - Result: client 38/38 suites 313/313 tests, server acadenice 21/21 suites 210/210 tests, 0 TS errors

+### Questions ouvertes a trancher post-/compact (2026-05-08)
+
+**Q1 — Strategie test E2E AI-driven (Claude Code / Stagehand / Computer Use)**
+- Constat : Playwright (R3.1.e livre) couvre les chemins critiques deterministes. Manque coverage exploratoire.
+- Option A : ajouter `R3.1.f Claude Code smoke` — workflow CI pre-release qui invoke Claude via Agent SDK avec acces Playwright + scenario en markdown. ~$0.50/run Sonnet, ~$2 Opus.
+- Option B : decaler en R4.x post-release stabilization.
+- Position complementaire (pas de remplacement Playwright) : Playwright = CI a chaque push deterministe, Claude smoke = nightly creatif decouverte UX.
+- Decision a prendre : R3.1.f ou R4.x ?
+
+**Q2 — Repartition Postgres DocAdenice vs Baserow (deja livre, audit possible)**
+- Regle implicite appliquee R3.2/R3.6/R3.7/R3.8 : Baserow = donnees user-visibles (les "databases" Notion-like que Ludo cree et regarde). Postgres DocAdenice = etat plateforme (auth, RBAC, contenu pages, notifs, comments, templates, backlinks).
+- 6 tables creees dans Postgres : `acadenice_backlink`, `acadenice_template`, `acadenice_notification`, `acadenice_notification_preferences`, `acadenice_page_comment`, `acadenice_row_comment`. Plus les 3 tables RBAC R2.1.
+- Justifications : FK CASCADE, latence <50ms requise pour panel backlinks, RBAC Docmost natif applique server-side, pas de pollution workspace Ludo, coherence yjs collab pour comments.
+- A reverifier ensemble si certaines de ces 6 tables devraient migrer vers Baserow (ex: templates editables comme une table user). Mon avis : non, mais ouvert au debat.
 
 ### TODO connus non bloquants
 - Hook `WorkspaceService.create` pour seed live RBAC (actuellement seed au prochain boot)
