swingset bootstrap config for vaults and oracles for a test network

[dckc]

What is the Problem Being Solved?

decentral-devnet-config.json doesn't include oracles.
decentral-core-config.json isn't sufficient to bootstrap vaults without splicing in proposals and addresses.

A nearby problem is a similar configuration for mainnet, but let's leave the details of that until we're closer to being able to test it on emerynet.

Description of the Design

Use fixed addresses with known mnemonics / keys.

Security Considerations

Be sure not to re-use the test accounts in production.

Scaling Considerations

This is sort of an attempt to scale up the number of users who can test our code straightforwardly.

Other than that, none that I can think of.

Test Plan

• Try it with agoric start
• Try integrating it into some of the smoketest scripts
• Try it with instagoric (see also Instagoric Support for vaults release #6956)

committeeSize 1 vs. 3

I have a draft and I'm trying it with agoric start local-chain. It got most of the way thru bootstrap but failed because one thing thought the committee size was 1 and another thought it was 3.

I've seen this before... odd... startEconomicCommittee doesn't seem to be part of the same manifest as inviteCommitteeMembers, startEconCharter, and inviteToEconCharter.

Validated the changed in the PR currently on instagoric, however two small tweaks to the bootstrap config will streamline network creation:

• Allow for initial price to be set in bootstrap for price feed
• Allow for UI hash to be included as a parameter in bootstrap for vaults

For the UI hash, we can use: bafybeidvpbtlgefi3ptuqzr2fwfyfjqfj6onmye63ij7qkrb4yjxekdh3e
and for the starting ATOM price, I think we can use 1234

[dckc]

hm. I assumed the initialPrice only needed to affect .makeQuoteNotifier . Evidently it needs to get into quoteGiven too.

        async maxDebtFor(collateralAmount) {
          trace('maxDebtFor', collateralAmount);
          assert(factoryPowers && priceAuthority);
          const quote = await E(priceAuthority).quoteGiven(
            collateralAmount,
            debtBrand,
          );

oops...

Sorry, an unexpected error has occurred.
amount's brand "[Alleged: SEVERED: IbcATOM brand]" must match ratio's denominator "[Alleged: SEVERED: IST brand]"

perhaps somewhere around https://github.com/Agoric/dapp-inter/blob/a9ce19316f42aa6562c3d230147e9e0b54ee6d95/src/components/MainContentWrapper.tsx#L58-L60

:published.vaultFactory.manager0.quotes was set to

        amountIn: {
          brand: slot(1,"Alleged: IST brand"),
          value: 1234n,
        },
        amountOut: {
          brand: slot(2,"Alleged: IbcATOM brand"),
          value: 100n,
        },

which looks like 12.34IST will get you 1 ATOM... but I guess the client wants to know how many IST they can get for 1 ATOM.
