/* Protobuf message definitions
 *
 * The original intention of these messages is for use as data elements sent
 * to and used in resolving GraphQL queries at the UI Server.
 *
 * This file is not needed at runtime. It is used to generate python protobuf
 * message modules.
 *
 * Command:
 * $ protoc -I=./ --python_out=./ --pyi_out=./ data_messages.proto
 *
 * Pre-compiled protoc binary may be download from:
 * https://github.com/protocolbuffers/protobuf/releases
 *
 * If merge/rebase conflicts arise, then regenerate the module.
 * (DO NOT manually resolve conflicts)
 *
 *
 * WARNING: Avoid re-indexing existing fields!
 *    - Field numbers do not need to be continuous/sequential (gaps are fine).
 *    - These numbers are used by the client to know which field they correspond to,
 *      so changing them can break back-compatibility (i.e. already running or old UIS).
 *    - If in doubt, just leave the current fields as is, and just take a number
 *      not in use for new fields.
