Application fees left behind

This detector asks whether platform fees survived on revenue that no longer exists, and computes proportional returns matching Stripe’s rounding exactly.

Formula and guard

Proportional share half-up; net-margin check prevents double-counting against reversals already made.

Currencies

Zero-decimal (JPY…) and three-decimal (BHD…) handled explicitly — display stays correct where naive division errs 100×.

Standalone fee refunds

Waivers and corrections reasoned from charge outward so legitimate operations never masquerade as leaks.

Worked example

$250 charge, $25 fee, 40% refunded → $10 owed back, flagged only if net position negative.
