53    "Strict format-1 graph source, owned copies, deterministic topological order, scalar/vector inference, source-path errors, missing/cyclic/disconnected links, declaration-order invariance and malformed/hostile node rejection.",
54    "Connected 32-node and 96-weighted-operation graphs compile and render natively; source/depth/constant limits reject before GPU submission.",
55    "Creator identifiers become numeric generated locals. Generated code contains engine-owned operations; native shader diagnostics map back to graph nodes.",
56    "Native compute dispatch and readback verify independently expected arithmetic outputs; a two-hour presentation clock still contributes its expected value.",
57    "Moss, gilt and lantern recipes compile all forward pipeline variants, have distinct shader identities and visibly change the scene; time changes the lantern image.",
58    "Held pipeline compilation leaves the accepted image visible. Invalid graph source and a native shader syntax failure preserve the accepted image and shader identity.",
59    "Six repeated graph/original replacements reproduce reference images with seven buffers and three textures. Actual device destruction followed by source-driven shader reconstruction restores the same image; final owned draw-resource census is zero.",
60    "The full native probe retains existing material, texture, skinning, animation, particle, lettering, physics and checkpoint controls."

62  "developmentFindings": [
63    "Review found that an initial \u00b14096 intermediate bound would clip a time input after about an hour. Changed it to \u00b110^12, which keeps the admitted arithmetic finite in float32 while covering ordinary world coordinates and multi-hour clocks; added the native two-hour check.",
64    "The initial full suite and isolated engine-pinning rerun failed three retained-engine cases on writes. A temporary diagnostic wrapper captured errno -122 (EDQUOT) in /tmp, without logging file contents. The unchanged full suite passed using an isolated workspace-disk TMPDIR, which was deleted afterward. No engine storage behavior, assertions or deadlines were relaxed.",
65    "A type-check caught overly narrow literal inference for the shared bound default; explicit numeric parameter annotations fixed it before final acceptance."
66  ],
67  "limitations": [
68    "No numbered milestone is closed; the full milestones 0\u201318 scope and approximate 75% estimate remain unchanged.",
69    "No saved-world graph material field, per-object catalog, shared revision transaction, editor workshop, graph undo or automatic player graph recovery is implemented by this foundation.",
70    "The study applies a single graph across its scene and reconstructs shaders explicitly after loss. Pipeline compilation is tested for all forward variants, but graph interaction with every imported texture/skin configuration is not separately qualified.",
71    "Admission costs are static weights, not GPU timing or hardware guarantees. Resource counts exclude native pipeline-cache memory; GPU pipelines have no explicit destroy API.",
72    "General texture/custom-normal/displacement/transparency nodes, effect graph outputs, physical-device measurements, Docker/Coolify execution, remote CI and final character/arrival art remain open."
