Fixes & Improvements

This update focuses on improving SimulationA accuracy, reducing false positives, strengthening movement detection, and tightening post-setback behavior while preserving legitimate Minecraft mechanics.

Fixes

Fix #1 — Entity Collision AirJump/Fly Bypass

• Fixed an issue where nearby entities could excessively inflate uncertainty values.
• Reworked uncertainty handling to distinguish between horizontal and vertical movement.
• Entity collisions now primarily affect horizontal prediction instead of broadly weakening all movement checks.
• Significantly improved AirJump and Fly detection reliability around:
• Players
• Mobs
• Boats
• Crowded combat situations
• Reduced opportunities for movement cheats to hide inside entity collision zones.

Fix #2 — SimulationA Elytra Swap False Positives

• Fixed false positives when swapping from an Elytra to a chestplate while airborne.
• Reworked Elytra transition handling to use phased momentum recovery instead of broad protection.
• Added improved handling for residual glide momentum.
• Reduced incorrect flags caused by legitimate Elytra exit behavior.
• Preserved detection capability during the recovery period.

Fix #3 — SprintB Elytra Transition False Positives

• Fixed SprintB incorrectly flagging players immediately after exiting Elytra flight.
• Added Elytra-aware transition handling.
• Improved movement direction analysis during momentum carry-over.
• Reduced false positives without weakening omni-sprint detection.

Fix #4 — Excessive Setback Exemptions

• Fixed overly long post-setback exemption windows.
• Reduced unnecessary grace periods following:
• Lagbacks
• Teleports
• Position corrections
• Movement setbacks
• Improved detection consistency after corrective actions.
• Eliminated situations where cheats could temporarily avoid detection after a setback.

Fix #5 — Uncertainty Classification Issues

• Fixed multiple uncertainty sources being applied as blanket movement uncertainty.
• Reclassified uncertainty sources based on whether they primarily affect:
• Horizontal movement
• Vertical movement
• Both
• Reduced cases where one environmental factor unintentionally protected unrelated movement.
