Venus reads the live game and only ever shapes the notes you would have missed: it delays, cancels, or creates a tap, drawn from a humanized timing profile it learns from your own play. Clean taps pass through untouched, so your accuracy is your own.
Catches the notes you would have missed, and when your rhythm slips it nudges your timing back on beat using the game's own feedback.
A per-key, per-difficulty timing fingerprint with warm-up and fatigue, so synthetic saves match the spread of your real taps.
Built around what osu! actually analyzes: the replay statistics, not flashy tricks. The humanization model is the product.
