@antseed/protocol

The AntSeed wire protocol as a standalone, dependency-light package (ethers only, no Node-specific APIs). Extracted from @antseed/node, which re-exports everything from its original paths, so existing consumers are unaffected.

Contents, one module per concern (each also available as a subpath export):

| Module | Contents | |---|---| | messages | MessageType, frame constants, all payment/verification/sweep payload interfaces, capability constants | | framing | 9-byte frame header codec (encodeFrame, decodeFrame, FrameDecoder, MessageMux) | | http | Serialized HTTP types, streaming/upload header names, upload thresholds | | request-codec | Binary HTTP request/response/chunk payload codec | | payment-codec | JSON codecs for the 0x50–0x5F payment messages | | json-codec | Bounded JSON parsing helpers | | signatures | EIP-712 SpendingAuth/ReserveAuth/EIP-3009 types + signing, metadata v2 encoding, computeChannelId, domains | | connection-auth | Signed intro/hello envelope wire format | | signing | EIP-191 domain-tagged signing (signData, signUtf8, …) and hex utils | | peer-id | PeerId branded type and helpers | | billing | Portable unit-billing metadata, usage reports, validation, and cost evaluation | | peer-metadata, capability, service-api, peer-pricing | Signed discovery metadata types | | connection-state | ConnectionState and connection config types |

Note: both signatures (SpendingAuth metadata, 2n) and peer-metadata (discovery records, 10) define METADATA_VERSION. The root export resolves to the payments constant, matching @antseed/node's public API; use the ./peer-metadata subpath for the discovery one.
