vault addCollateral proposal updates

[0xpatrickdev]

Reproducable Bundles:

I am working off of this: Agoric/agoric-sdk@master...0xpatrickdev:agoric-sdk:pc/statom-vault-proposal

• node v16.18.1, go1.20.2 darwin/arm64, agoric-sdk#9d4eaad

What was added

• removed economicCommitteeCreatorFacet and contractGovenor from oracle permit: Agoric/agoric-sdk@b414246 (see minor: startGovernedUpgradable subsumes economicCommitteeCreatorFacet etc. #5)

• updated README instructions to suggest single proposal (see scripts need not go in separate proposals #6)

• use STATOM1 in proposal for now (see use correct denom for emerynet, mainnet #1, start with non-vbank ERTP asset? #10)

• update oracle operator addresses (decentral-devnet-config + pc address) (see Oracle operator addresses from mainnet should not be used for testing #3)

• docs for oracle flow, and REPL validation

What is missing

• I attempted to tackle priceAggregator, scaledPriceAuthority contracts are already installed #7, restoreRef for priceAggregator and scaledPriceAuthority, but couldn't quite figure this out. I am not sure yet what needs to be changed so we have access to restoreRef in add-collateral-core.js.

Testing Status

I included ibc/toystatom in all the places that have ibc/toyatom in cosmic-swingset/Makefile, and this enables me to access test statom1 in the repl and other wallets.

I am (seemingly) able to submit oracles prices using the agops cli, but am getting a maxDebtFor called before a collateral quote was available error when opening an stATOM vault. This error occurs when storedCollateralQuote is undefined, so it seems I may be missing a step. Oracle prices must be sent from 2-3 addresses/operators, before the price registers. Once I included this in the flow, things are working as expected 🎉

This is good progress. Several of the fixes look good.

If they were in their own PR(s), I would approve them, but I'm not sure what to do with this whole PR.

ok. I get it now. this addresses the issues in "what was added"
