Creates a new asset in your organization. The asset is automatically linked to the specified program on creation. All fields are required:

program_id: the program to link this asset to
name and symbol: display name and short code
inventory_mode: SIMPLE tracks a single balance per participant; LOT tracks individual batches with expiration, vesting dates, oldest-first spending, and issuer lineage
issuance_policy: UNLIMITED mints value on demand with no budget cap; PREFUNDED draws from the program wallet
scale: decimal precision from 0 to 18 (e.g., 2 for dollars and cents)

The inventory_mode, issuance_policy, and scale fields are immutable after creation because they affect how the ledger records and resolves balances. If you need a different configuration, create a new asset.

For usage patterns and examples, see the Asset Configuration guide.
