The `FAILED_HATCH_PUNISHMENT` parameter should be dynamic, defined in terms of committee size/stake.

Edit: Remove `BOND`, because an attacker will just borrow the required tokens.  
Your pricing strategy fails to account for short positions where the attacker profits from a token crash.

Doesn’t seem impractical. Deploying a smart contract that reads the L2 state and pays out colluders is trivial enough that an LLM could write it today.

Replace `WITHDRAWAL_TAX` with a simple time lock.

Use the L1 aution instead of registering+lottery (just-in-time bond).

At the proposed hatch-rate, how many users can exit within 30 days?
