feat: MGP-19 — return issuance governance to Celo Governance - #90
Conversation
Adds script/migration/MGP19.sol, which transfers proxy-admin and owner rights over the issuance side of the protocol on Celo (15 stable assets, Broker/BiPoolManager/Reserve, ReserveV2 + reserve/CDP liquidity strategies, ReserveTroveFactory, CDP FXPriceFeeds/SystemParams/StabilityPool proxies, SortedOracles/BreakerBox/breakers/ChainlinkRelayerFactory) to Celo Governance. Rights are routed to whichever sender holds them today: the Mento timelock (governor proposal, 26 txs) or the migration multisig (Safe batch, 35 txs). Pre-checks reject unexpected holders; post-checks verify Celo Governance holds every right, that DEX/DAO contracts are untouched, and that Celo Governance can exercise the transferred powers. mgps/mgp19.md is the proposal text; mgps/mgp19-ownership-survey.md is the on-chain ownership survey (block 75138312) backing the classification.

- mgps/mgp19.md now carries the full proposal (TL;DR, motivation, §1-§4, reserve impact) with the on-chain execution detail for §1 (Step 1 governance proposal, Step 2 migration multisig batch, follow-ups). - src/ProposalDependencyGuard.sol: stateless helper whose requireSettled() reverts while a given Governor proposal is Pending/Active/Succeeded/Queued. MGP19 optionally (env dependsOnProposalId) queues it as the first proposal tx so MGP-19 cannot execute before MGP-18 has executed (or died), while both can be voted on concurrently. Guard is CREATE3-deployed by the script if not yet registered; the call is mocked for the proposal-time simulation only and verified in post-checks. - unit tests for the guard (test/unit).

Describe the implemented settlement condition.
This text says MGP-19 waits until MGP-18 has executed. ProposalDependencyGuard.requireSettled also permits Canceled, Defeated, and Expired states. The fork test confirms that a Defeated dependency permits execution.
Replace “has executed” with “has settled”, or change the guard if execution is the required condition.

Enforce the MGP-18 dependency for both execution legs.
Line 210 disables the dependency when dependsOnProposalId is absent. Lines 216-218 add the guard only to the Mento Governance proposal. The migration Safe batch has no on-chain precondition and can execute before MGP-18, despite mgps/mgp19-ownership-survey.md stating that its MGP-18 BiPoolManager operations must run first.
Require a nonzero dependency ID for the mainnet MGP-19 run. Add an equivalent settled-state check as transaction 0 of the migration Safe batch. Add a fork test for an early Safe-batch attempt.

MGP-19: Bringing Stable Asset Issuance Home to Celo Governance
On-chain companion to the forum proposal (§1: transfer of issuance governance to Celo Governance). Draft — proposal text still carries the forum draft's TBD placeholders (yield split, ETH-family amounts, dates).
What's in here
script/migration/MGP19.sol— transfers proxy-admin + owner rights over the issuance side on Celo to Celo Governance (0xD533…7972, verified via the Celo Registry). Rights are today split between the Mento timelock and the migration multisig (MGP-14/16), so the script drives two senders and routes each right to whoever holds it, reverting on any other holder:governor→ 26 txs (10 StableTokenV2 tokens, Broker, Reserve: proxy admin + owner; BiPoolManager & SortedOracles: proxy admin) + 1 ordering-guard tx when enabledmigrationOwner→ 35 txs (USDm/EURm/GBPm/CHFm/JPYm, owner of BiPoolManager/SortedOracles, breakers, ReserveTroveFactory, ChainlinkRelayerFactory owner, ReserveV2/RLS/CDPLS/FXPriceFeed×3 ProxyAdmin+owner, SystemParams×3 + StabilityPool×3 ProxyAdmin)src/ProposalDependencyGuard.sol(+ unit tests) — ~20-line stateless helper;requireSettled(governor, id)reverts whileidis Pending/Active/Succeeded/Queued. With--env dependsOnProposalId=<MGP-18 id>the script CREATE3-deploys it (if unregistered) and queues the call as tx 0, so MGP-18 and MGP-19 can be voted on concurrently but MGP-19 can't execute before MGP-18 has executed (Queued-in-timelock counts as not settled; too-early execution just reverts and MGP-19 stays Queued). Rationale for a new contract: OZ TimelockController'spredecessoris the native primitive but GovernorTimelockControl hard-codes it to 0, and no already-deployed call has the right revert polarity. The proposal text mentions it only as transaction 0.mgps/mgp19.md— full proposal text (forum lean version merged with the on-chain transaction tables, security considerations, follow-ups).mgps/mgp19-ownership-survey.md— on-chain ownership survey at block 75138312 backing the issuance / DEX / DAO classification.Verification
Both dry-runs green (26+35 / 27+35 txs). Note: repo

Note
High Risk
Transfers owner and proxy-admin rights over all Mento issuance contracts (stables, reserve, CDPs, oracles) to Celo Governance via a two-leg governance + multisig batch. A mistake in routing or sequencing would permanently change who can upgrade and parameterize the protocol.
Overview
Adds MGP-19: on-chain transfer of Mento issuance governance (15 stables, reserve mint/burn, CDPs, oracle/breaker layer) to Celo Governance, leaving the FX DEX and MENTO DAO with Mento.
script/migration/MGP19.solbuilds two batches from live holders: a Mento Governor proposal (~26–27 txs from the timelock) and a migration-Safe batch (35 txs). It reverts if any in-scope right is held by anyone else, then asserts Celo Governance can actually upgrade/configure those contracts and that DEX/DAO ownership is unchanged. OptionaldependsOnProposalIdCREATE3-deploysProposalDependencyGuardso MGP-19 cannot execute while MGP-18 is still Pending/Active/Succeeded/Queued.Proposal text, Celo proxy-vote CGP, forum drafts, and an ownership survey at block 75138312 document the split, CELO/ETH authorizations, and follow-ups (ChainlinkRelayerFactory ProxyAdmin still on a legacy Safe; CDP feeds still read through the DEX
OracleAdapter). CI pins Foundry tov1.7.1.Reviewed by Cursor Bugbot for commit 3c0de83. Bugbot is set up for automated code reviews on this repo. Configure here.
