CAC-based Contract Engine

The Mathematical Engine

1. Loss Protection (0% Floor): If the client's overall Net Margin is zero or negative, the Developer fee drops to 0% so as not to increase the client's loss.

2. Anti-Bankruptcy Clamp (1% Floor): If the client is profitable but the standard Developer fee would wipe out his remaining margin, the fee is blocked and drops to a flat 1% so the client still takes some profit home.

3. The Bonus: The Developer base fee is 5%. For every 100 BDT the Actual Ad CAC drops below the Bleeding Point Baseline, the Developer fee dynamically increases by 1%.
