# ERC-7540 Async-Vault Request Accounting

`POST /v1/tools/recompute_erc7540_request_accounting`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/recompute_erc7540_request_accounting`
- Auth: none declared

Recomputes ERC-7540 asynchronous-vault request accounting from caller-declared request state. ERC-7540 extends ERC-4626 with a three-state request lifecycle used by 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 calls deposit, mint, withdraw or redeem. This tool 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 invariants by name. ERC-7540 mandates no rounding direction for a partial claim, so the direction is a declared parameter and the opposite direction's result is reported beside it. Never reads any chain: it cannot know whether the declared amounts match a deployed vault, when a pending request will be fulfilled, whether the controller is authorised, or whether a claim transaction would succeed.
