Nine categories, nine ceilings
Every bonus in the game belongs to one of nine categories, A through I: genetics, deviation, rupture, social and guild, apparatus, account and prestige, progress, temporary, and signed acceleration. Each category carries its own ceiling, and each ceiling is published. A bonus that fits no category does not exist.
One engine applies the limit
No system applies its own bonus. Every system declares its contribution to a single engine that composes the stack and enforces the cap. Exclusions live in the same place: deviation and rupture never coexist, and rupture occupies the apparatus slot rather than stacking beside it.
The numbers are the contract
Legal damage ceiling is 8,86×. Peak per blow is 47,8× — the figure the anti-cheat assumes, so anything above it is rejected as impossible rather than debated. Rate bonuses to EXP and loot stop at ×1,875. A ceiling that cannot be proven is not a ceiling, so the build runs tests that demonstrate each limit before shipping.
