Spikes

Decision records. Each one is a question that was open, the options weighed, and what was chosen.

A spike is reference work: it stands on its own and is read on its own terms. Each page states its settled design without pointing here, so nothing in the wiki depends on reading a spike first. Come here when you want to know why a thing is the way it is.

Spike	The question it settled
Ball State Ownership	Who owns a ball's placement, and what the ball's own state machine is left holding.
Equip Loop Regime	What happens when an item is released somewhere that is not a container. The home and loose model.

Paddle Sprite Sizing	Splitting how big the paddle looks from how big it plays.
Racket Position Per State	Where the racket sits during the low swing.
Surface Physics Ownership	Which resource owns rest roll damping.
Web Export Threading	Shipping the threaded web build.
Web Lag RCA	Why the web build stuttered.
