}

Optional margin section of the deploy config: the prop margin pool, the prop account oracle, the price feed and the tier catalogue.

Fields

price_feed: MarginPriceFeedConfig

The price feed: its own contract, its own section.

price_feed_id: Option<ContractId>

The RETIRED flat spelling of price_feed.id, present only so that a stale config is REJECTED rather than silently ignored.

Silence here is catastrophic rather than untidy: an unread feed id means the run derives a FRESH feed, and the pool-feed reconcile then moves a live pool onto an oracle nobody publishes to. Every valuation, liquidation and session open fails afterwards.

Never serialized, so the write-back drops it once migrated.

margin_pool_id: Option<ContractId>

TIER-ONLY mode: run no system deploy, only reconcile the tier catalogue (and the feed’s roster/assets when configured) against this already-deployed pool.

platform_payout: Option<String>

Identity receiving the platform profit share, prefixed with its kind (address:0x.. / contract:0x..). Defaults to the deployer.

discount_managers: Vec<String>

Identities that must HOLD the pool’s discount-manager role - the only role set_user_discount accepts, the admin included - each prefixed with its kind (address:0x.. / contract:0x..). Reconciled compare-first: an identity that already holds it costs no transaction. When empty, nothing is granted and NOBODY can price user discounts.

A ROSTER, so it lives in the config beside the feed’s publishers rather than in a deploy flag: the cosigner and the liquidator are flags because they name the operator’s own key and payee, while this is a list the deployment owns and carries forward run to run.

remove_discount_managers: Vec<String>

Identities that must NOT hold the discount-manager role, same prefixed form, revoked only if currently held.

An explicit list for the same reason remove_publishers is one: roles are a bitmap keyed BY ACCOUNT with no reverse index, so “revoke everyone not in discount_managers” is not a question that can be asked on chain, and inferring it from config absence would silently kick out a manager granted out of band.

Revoking stops FUTURE writes only: discounts the manager already granted stay in force until cleared.

collateral_asset: Option<AssetId>

Collateral asset of the pool. Defaults to the quote asset of the first configured pair.

collateral_decimals: Option<u8>

Collateral asset decimals. REQUIRED: a wrong figure misprices every valuation the pool makes, so there is no default to fall back to.

max_tier_books: Option<u64>

Maximum order books one tier version may hold. Defaults to 80.

base_repay_fee_ppm: Option<u64>

Fee charged by repay_base_from_collateral, in PARTS PER MILLION of the quote value of the debt closed - the order book’s TAKER_FEE scale, so 100 is one basis point. Defaults to 100.

It is a pool CONFIGURABLE, so changing it here only takes effect on a deploy or an implementation upgrade (--upgrade-bytecode), never on a tier-only reconcile against an already-deployed pool.

tiers: Vec<MarginTierConfig>

The desired tier catalogue; reconciled idempotently (§ tier engine): unchanged tiers are untouched, grown book lists use add_books, any param change publishes a NEW version.
