Clarify for each docs/tech document whether it describes the current (implemented) or target (planned) architecture, and reconcile with the readme/roadmap source of truth: - ARCHI_APP, ARCHI_CPU_GPU, ARCHI_RENDU: mark status=target and add a banner stating the GPU-driven two-pass pipeline, persistent VRAM buffers and scene auto-render are not implemented (they are ROADMAP Phase 3 / README roadmap items 1-3). render() still cannot draw the scene. - ARCHI_ARENES: status=target/deferred. String IDs are the current design; slotmap generational handles are the deferred 'typed handles' step and the slotmap dependency is currently absent (supersedes the retired dep). - FRAME_LOOP: stays status=current; correct the described API flow (Frame based via get_next_frame/Renderer::present, plus the low-level begin_frame/end_frame variant) and move the single-buffer VRAM note to target. - README: label each tech doc as current or target in the Documentation section.
