debugViz_driver

The ambient edit-mode debug-visualization driver. Requiring it registers the built-in providers (bounds, frustum, bones, colliders, icons, wireframe) with @builtin::modules.debugViz; the editor entrypoint requires it and calls tick(dt) every frame.

local DebugVizDriver = require("@builtin::modules.debugViz_driver")

-- In the editor entrypoint's per-frame hook:
DebugVizDriver.tick(dt)

• register() — register the built-in providers. Idempotent: registerProvider replaces by name and a guard makes a re-require a no-op, so a category toggled off in the panel survives a module reload. Called on require and by tick.
• tick(dt) — per-frame hook for both modes. Edit mode always rebuilds the overlay; play mode rebuilds only while a debug session is active (debugViz.setPlaySession) and otherwise clears the batch, so play mode carries no debug-draw cost by default.

There is no per-entity opt-in — the overlay is editor tooling, driven here for the whole scene. Toggle categories through the Debug → Visualization panel or the debug toolbox.
