/**
 * Encodes a direct Midnight credit redemption.
 *
 * Use this low-level builder after the caller has fetched and checked position
 * credit and market withdrawable liquidity. App flows should usually call
 * `client.morpho.midnight(chainId).redeem(...)`, which performs those checks
 * from the supplied `positionData` snapshot before exposing `buildTx`.
 *
 * @param params.chainId - Chain id used to resolve `Midnight`.
 * @param params.market - Midnight market whose credit is redeemed.
 * @param params.units - Credit units to withdraw.
 * @param params.onBehalf - Account whose credit balance is reduced.
 * @param params.receiver - Optional receiver for withdrawn loan assets; defaults to `onBehalf`.
 * @param params.metadata - Optional analytics metadata appended to calldata.
 * @returns A deep-frozen `Transaction<MidnightRedeemAction>` targeting `Midnight`.
 * @throws {NonPositiveInputError} when `units <= 0n`.
 * @throws {ChainIdMismatchError} when the market targets another chain.
 * @throws {MidnightMarketAddressMismatchError} when the market targets another Midnight deployment.
 * @example
 * ```ts
 * import { midnightRedeem } from "@morpho-org/morpho-sdk";
 *
 * const tx = midnightRedeem({
 *   chainId: 8453,
 *   market: marketData.params,
 *   units: positionData.faceValue,
 *   onBehalf: user,
 * });
 * ```
