The vault must have fresh pricing records for the operation; fee or fulfillment math depends on NAV values written by the pricing flow.
The request queue or escrow account must contain the expected request state for the signer, request type, timing window, and amount being processed.

Policy & permissions

Permissionlessness is controlled by notify_and_settle.permissionless_fulfillment.
When permissionless, any signer can fulfill queued requests.
Otherwise the caller must be the GLAM owner or a delegate with Mint Fulfill.

TypeScript SDK usage

const preInstructions = await glamClient.price.priceVaultIxs();
await glamClient.invest.fulfill(null, {
  preInstructions,
  lookupTables: glamClient.price.lookupTables,
  simulate: true,
});

Cross-instruction constraints

Requires fresh pricing for the vault. The pricing operation itself must be atomic in a single transaction.
