Context Audit

This is the current high-level status of the context and renderer stack.

Surface	Status	Notes
`core.context`	Active	Shared context abstraction used everywhere.
`context.*` multiplexer/window/control/type/platform_utils	Active	Core windowing and command-routing layer.
`opengl.*`	Active	Primary GPU renderer path.
`sdl.*`	Active	Important desktop backend; Windows dock-host rendering is active and still being smoke-tested against GUI regressions.
`raylib.*`	Active	Active and feature-rich, especially for docked-window workflows.
`sfml.*`	Active	Supported, but still more delicate due to GL/context behavior and dock-host activation order.
`software.*`	Active	Fallback/debug path.
`noop.context`	Minimal	Headless placeholder.
`vulkan.*`	Experimental	Under active migration, not a stable default backend.
`opengl.renderer`	Review candidate	Looks more archival than central; keep under review.
Retired legacy context stack	Retired	Historical snapshots have been removed; keep migration work in active modules and documented feature maps instead.

Practical guidance

Prefer module-backed active context surfaces under Engine/modules/ and Engine/src/.
Use the active modules plus legacy_feature_map.md for migration help, not deleted archive snapshots.
On Windows, launch multi-context smoke runs from the asset-bearing output directory so docked backend panes do not drift away from the editor host's runtime assets.
Treat Vulkan and a few minor archival helpers as incomplete until their paths are explicitly finished and tested.
