    weekly_retention_rate: u16,
    user_weight: u16,
    activity_weight: u16,

) -> Instruction

Builds an update community metrics instruction.

• weekly_active_users: Number of active users in the past week
• weekly_retention_rate: Retention rate in basis points (0-10000, 0-100%)
• user_weight: User weight in basis points (0-10000) for weighted geometric mean
• volume_weight: Volume weight in basis points (0-10000) for weighted geometric mean
• retention_weight: Retention weight in basis points (0-10000) for weighted geometric mean

Returns

An instruction that can be included in a transaction to update community metrics.

Security

• The oracle must be a signer of the transaction
• Input validation occurs on-chain
• Only the authorized oracle can update metrics

Example

use steel::Pubkey;
let oracle_pubkey = Pubkey::new_unique();
let instruction = miracle_api::sdk::update_metrics(
    oracle_pubkey,
    5000,        // 5,000 active users
    7500,        // 75% retention rate
    4000,        // 40% user weight
    3500,        // 35% activity weight
    2500,        // 25% retention weight
    50_000,      // 50,000 transactions
    7000,        // 70% customer reward share
    3000,        // 30% merchant reward share
