Onchain.Aave.V4.Oracle (onchain_aave v0.4.0)

Aave V4 Spoke-scoped oracle reads.

V4 has no protocol-wide oracle. Each Spoke owns an IAaveOracle (resolved via ISpoke.ORACLE()), and prices are keyed by Spoke reserve id, not underlying asset address. Pass a Spoke address instead of a network.

V3 BASE_CURRENCY / BASE_CURRENCY_UNIT / getFallbackOracle have no V4 equivalent — decimals/2 is the price scale (V4 oracles are 8 decimals). Direct Chainlink / IPriceFeed reads take a feed address, not a Spoke.

Error Format

Errors pass through from the underlying module that failed:

Source	Error Shape
`Onchain.Address.validate/1`	`{:error, {:invalid_address, input}}`
`Onchain.Contract.call/5`	`{:error, {:encode_error, ...}}`, `{:error, {:rpc_error, ...}}`, `{:error, {:decode_error, ...}}`
