Struct MarginPriceFeedConfig 

pub struct MarginPriceFeedConfig {
    pub id: Option<ContractId>,
    pub max_offchain_age_seconds: Option<u64>,
    pub publishers: Vec<String>,
    pub remove_publishers: Vec<String>,
    pub supported_assets: Vec<MarginSupportedAsset>,
}

The price_feed sub-section: everything about the ORACLE the pool values against, kept apart from the pool’s own settings because it is a separate contract with its own lifecycle, ownership and roles.

Fields

id: Option<ContractId>

Reuse an existing feed. None deploys the production price feed behind its own SRC-14 proxy.

max_offchain_age_seconds: Option<u64>

Submission-age bound in seconds, reconciled compare-first. None leaves whatever the feed enforces today.

publishers: Vec<String>

Identities that must HOLD the submitter role, each prefixed with its kind (address:0x.. for a wallet, contract:0x.. for a publishing contract). Reconciled compare-first: an identity that already holds it costs no transaction. When empty, nothing is granted and only the feed’s owner may publish.

remove_publishers: Vec<String>

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

An explicit list on purpose. The feed stores roles as a bitmap keyed BY ACCOUNT with no reverse index, so neither the contract nor this deploy can enumerate who holds the role - “revoke everyone not in publishers” is not a question that can be asked on chain, and inferring it from config absence would silently kick out a publisher granted out of band.

Revoking stops FUTURE writes only. A price the publisher already pushed stays live until it ages out or is invalidated explicitly.

supported_assets: Vec<MarginSupportedAsset>

Assets the feed supports, registered by their decimals before any price exists. Reconciled compare-first: an asset the feed already knows at the SAME decimals is skipped, an unknown one is registered, and a DISAGREEMENT is refused rather than overwritten. The pool pins an asset’s decimals on first use and rejects a later change, so silently moving them here would strand it.
