      summary: Vault-scoped oracle prices
      description: 'Supports exact mode (`chainId + vault + asset`) and list mode (`chainId` + pagination).

        - Exact mode requires the full key.

        - Exact mode returns `200` with `price: null` when the tuple is known but currently unpriced.

        - Non-null `price` values are exact contract-derived prices encoded as 18-decimal bigint strings in `unitOfAccount` terms.

        - Exact mode returns `404` only when the `(chainId, vault, asset)` tuple is unknown.

        - Partial exact key requests return `400`.

        - List mode returns flat rows sorted by `vault ASC, asset ASC`.'
