Crash log from the shipped v0.9.5+mc26.3 (01:34 2026-09-19, client):

Mixin apply for mod anglesnap failed GameRendererMixin -> GameRenderer:
InvalidInjectionException: @Inject::resetBobMatrix(Lnet/minecraft/client/DeltaTracker;...CallbackInfo;)V
Expected (CallbackInfo)V but found (DeltaTracker;CallbackInfo)V
-> RuntimeException: Mixin transformation of net.minecraft.client.renderer.GameRenderer failed

Root cause (verified against fabric-loom 26.3 minecraft-merged.jar with javap):

26.3 GameRenderer.renderLevel() no longer takes a DeltaTracker parameter (26.2 was renderLevel(DeltaTracker)). The injected handler must be resetBobMatrix(CallbackInfo); any other descriptor makes Mixin fail at boot. Both the released 0.9.5/0.9.4 jars and origin/main still carry the old 26.2 signature.
Second latent bug in the same jars: MinecraftClientMixin shadows the screen field on Minecraft, which no longer exists in 26.3 (it moved to Gui). 0.9.5's client.gui.screen()/gui.setScreen() rewrite was correct; this fix restores that access for the null-check and keeps setScreenAndShow(Screen) (the method still exists in 26.3 and does exactly what it did in 26.2: gui.setScreen + a forced renderFrame).
bobHurt/bobView and MouseMixin targets were verified unchanged in 26.3.

Changes: GameRendererMixin handler signature; MinecraftClientMixin screen access; mod_version 0.9.4+mc26.3 -> 0.9.8+mc26.3 (0.9.5 was the last shipped tag).
Pins: minecraft 26.3, loader 0.19.5, fabric-api 0.160.7+26.3 (unchanged on main). Local ./gradlew build green.
