autotune, autoskill and confidence each carried their own idea of what an improvement is, and autotune's two efficiency rules were the same sentence twice. They now route to one skill that names three axes to move at once — fewer tokens, less time, higher quality — and the rules that decide when a proposal counts: at least one axis better, none damaged, quality never the currency, observed friction instead of a guessed percentage. Applying its own rule, autotune gets shorter rather than longer. The test holds the coupling, so a later rewrite cannot silently drop a route.
