R11M.4 — Native HDR lighting, deterministic exports and complete turret parity

This release combines the complete R11A–R11L native lighting line with the R11M.4 runtime repair. The engine now uses one protected rendering and gameplay contract across Level Editor, Test Game, Windows EXE, EXE Developer, HTML5 and HTML5 Developer. The goal is not only better graphics: it is to make the same project behave, look and simulate the same way in every place where the creator tests or publishes it.

1. What the native lighting pipeline actually does

• Twenty-one compiled Windows x64 lighting DLLs split the renderer into focused modules: GPU capability checks, G-buffer creation, scene submission, HDR light accumulation, tiled culling, PBR materials, SDF shadows, temporal stabilization, bloom, color grading, volumetric fog and performance diagnostics. This modular design keeps heavy native work outside the Python frame loop while preserving protected Python/OpenGL fallback paths.
• The renderer works in linear HDR space, so lights can carry energy above 1.0 before tone mapping. Materials respond through physically based rules instead of a simple brightness overlay, while shadows and post-processing are cached, budgeted and allowed to fall back independently if one optional pass fails.

2. Runtime parity and turret behavior

• R11M.4 moves all five turret families onto a deterministic HTML scheduler. Ice can chill and then freeze; Gum reduces speed, jump and dash freedom while applying a tether pull; Gas stacks duration and changes controls on a fixed schedule; Fire creates a terrain-aware stream with burn and heat; Corrosive Acid fires a three-shot burst and progressively cuts small cells from damageable terrain.
• Acid erosion is no longer only a visual effect. The runtime maintains a polygon-aware terrain mask, rebuilds collision after material is removed, stores the erosion mask for later frames and spreads acid pools along reachable surfaces. This makes the same acid hole exist in gameplay, collision and rendering instead of appearing only on screen.
• The HTML presentation was also cleaned: the unintended center health bar, browser-only grid/vignette/letterbox glow and duplicate WebGL post-processing were removed. Camera shake is off unless a project explicitly enables it, and the shake offset is calculated once per frame so jumping does not create a different browser-only view.

3. Codebase scale and verification

• The package contains 392 Python files with 84,021 physical lines and 26 Rust source files with 6,989 physical lines. The main source languages together contain 97,382 physical lines. DLLs are compiled binaries, so they are reported as 21 deployment lighting modules plus the separate performance core rather than as “lines of DLL code.”
• Verification covers both source structure and runtime behavior: R11M.4 turret parity passed 34/34 checks, the active-level repair passed 9/9, the R11L pipeline passed its native build and compatibility suites, and headless Chromium completed the HTML runtime without JavaScript or startup errors. These checks confirm the shipped logic, while long-duration testing on a broad real-hardware matrix remains a roadmap task.
