Reversed create/set/draw-texture handlers + gfx_render_frame: surfaces at ctx+0x52bd4[slot] (set-texture loads a file with a colorkey); objects in the ctx+0x408 registry reference a surface by slot (live) + rect + position (V24) + visible bit; render iterates the registry in ASCENDING HANDLE ORDER (= z-order) and composites visible objects. Answers both unknowns (z-order = handle; slot 0 not special). Design spec + Phase 1 plan rebuilt on this model, replacing the flawed flat-layer version. Ghidra annotated (gfx_op_0x1f8/9/b, gfx_object_bind_draw, gfx_render_frame, gfx_object_composite, gfx_op_0x20c_present_frame). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
