• Date: 2026-05-27
• Source: packages/host-api/src/protocol/impl.ts (variant order) + packages/host-api/src/protocol/messageCodec.ts (flattening)
• Methods: 54 (43 request, 11 subscribe)
• Variants (wire tags): 130 of max 256
• Remaining capacity: 126 variants before the single-byte discriminant overflows

The discriminant is one byte; index 255 is the last representable value.
