Quell Godot Developer Alpha is a native GDExtension package for evaluating Quell's real-time visual analysis and mitigation path in Godot projects.

Version 0.3.0-developer-alpha replaces the previous adaptive mitigation controller with Quell's hard constrained projection engine: mitigation is driven by regional temporal hazard fields (luminance and saturated red) with frame-rate-normalized dynamics, so correction stays localized to hazardous regions instead of washing out the whole frame. The public runtime interface is unchanged: QuellRuntime.enabled is the supported on/off control, while analyzer, feedback, sampling, solver, and mitigation-policy settings are internal developer-alpha preset details.

Why this update: the mitigation controller in earlier developer alphas (0.1.0 and 0.2.0) could fail to keep the corrected output below flash detection thresholds in some situations. 0.3.0 replaces that controller, and each 0.3.0 package is verified against Quell's internal benchmark release gate (saved-frame re-analysis plus an external flash detector) before packaging. This verification covers the internal benchmark only: it does NOT guarantee that mitigated output passes every detector, in every situation, or for all content. Treat 0.3.0 as an experimental developer evaluation build, not a safety guarantee.

This developer alpha is intended for engine/runtime evaluation and integration prototyping. It exposes the native QuellRuntime class and always renders the Quell logo, quell.komm64.com, and the internal Raw/After Risk graph into the final output. Those markings are intentionally part of the developer alpha, so this package is not suitable for product builds.

The first public package supports Windows x86_64 only. Linux and macOS builds are not included in this alpha package. The current native binary has been smoke-tested with Godot 4.5-stable and the local Godot 4.6 build; Godot 4.3 and 4.4 do not load this GDExtension binary.

This package is not a medical device, diagnostic tool, prevention or treatment tool, certification service, standards-conformance checker, or guarantee that content is safe for photosensitive viewers. Raw Risk and After Risk are internal Quell software signals, not clinical risk estimates.
