Reserve collects liquidity held by AMM from creating new pools

[Chris-Hibbert]

What is the Problem Being Solved?

See https://github.com/Agoric/agoric-sdk/pull/5377/files#r877423297

#5377 changed the process for adding new pools to the AMM to enforce a minimum liquidity, and hold the corresponding liquidity tokens for the reserve.

Description of the Design

? How should the reserve receive the funds?

• PULL
  • + In general, pull is more reusable. Downside
  • - requires polling, especially wasteful given that pool creation is rare
• PUSH
  • simpler to wire up
  • matches liquidation penalty proceeds to reserve #5387

Decision: PUSH

Security Considerations

legibility, bootstrap dependency issues. This needs to be done in a way that is visible and subject to governance, without allowing the process to be subverted.

Test Plan

test deliver of funds. proving security properties is external to the testing.
