Hardened score/race anti-cheat and multiplayer integrity (da12994)

2026-03-31

Dev-mode multiplayer bypass with bot simulation, so races can be tested solo (ac59fbf)

Opt-in challenge mods (Fog, Headwind, Tremor); each applies a 1.15× score multiplier that stacks multiplicatively (two = 1.322×, three = 1.521×). Runs using a beta mod are unranked, and the multiplier is re-derived server-side to prevent forgery (627fd45)

Hardened achievement/skin awarding to prevent cascading failures (0e478c4)
