- Regular combined fee and creator tax: at most 20%.
- Protocol share of the fee bucket: at most 50%.
- Anti-snipe window: at most 60 seconds; starting setting at most 10,000 bps.

- Minimum output for guarded swap operations: non-zero.
- Graduation price discontinuity: at most 1%.
Which values can change?
Section titled “Which values can change?”The owner can update quote settings, defaults, and future-launch infrastructure. Existing gauges retain their curve parameters, allocation, fee rates, initial anti-snipe settings and infrastructure. Creator tax is fixed at launch. The current recipient may change fee recipient and buyback preference under the contract’s authorization rules.
The pool’s base hook rate is copied from its adapter at graduation. Read the adapter’s launch state after graduation instead of inferring it from the current factory curve fee.
