Verify one daily allocation decision against the hash stamped on-chain that day. Returns the exact payload the receipt commits to (the date, the three RWA weights, and the market signals the model read), the hash recomputed live from the stored record, the hash written at stamping time, the anchoring transaction, and the wallet that must have signed it. The guarantee is on-chain, not this response: serialize the committed payload canonically, sha256 it, and check that the memo read from Solana is exactly vaultbags:alloc:v1::gsu:, in a transaction signed by the VaultBags treasury (a wallet you hold fixed, not one this response names) that landed on that UTC day, since a decision stamped after the day it governs is a backfill. Proves the decision published is the decision stamped, before the vault acted on it. Read-only.
