description: "Recomputes ERC-7540 asynchronous-vault request accounting from caller-declared request state. ERC-7540 (Final, Created 2023-10-18, CC0-1.0) extends ERC-4626 with a three-state request lifecycle used by institutional and real-world-asset funds that cannot settle a deposit or redemption in the same transaction: an amount is Pending after a request, becomes Claimable when the vault fulfils it, and is Claimed when the holder finally calls deposit, mint, withdraw or redeem. This node applies a sequence of claims against the claimable buckets at the pro-rata rate they were made claimable at, tracks the pending, claimable and claimed split for both legs, reports the rounding residue a sequence of partial claims strands, and checks the standard's own invariants by name: pending and claimable are disjoint views, a claim never short-circuits the Claim state, a claim never exceeds what is claimable, and a request with a non-zero requestId stays at a single pro-rata rate. ERC-7540 mandates no rounding direction for a partial claim, unlike ERC-4626 which fixes one per function, so the direction here is a declared parameter and the result of the opposite direction is reported beside it rather than a direction being presented as required. All arithmetic is exact uint256 integer math with no floating point. This node never reads any chain: it cannot know whether the declared amounts match a deployed vault, when or whether a pending request will be fulfilled, whether the controller is authorised, or whether a claim transaction would succeed."
