/**
 * # protocol/wire — the PLATFORM HTTP/SSE wire shapes (kestrel-5rb, OSS-ADR-0046).
 *
 * The single, authoritative TypeScript mirror of the kestrel.markets contract as
 * served on the wire: **snake_case** bodies + the canonical SSE `OperationEvent.type`
 * vocabulary, transcribed from
 * `kestrel.markets/packages/contracts/openapi/kestrel-markets.openapi.json`
 * (schemas TrialCapability / ValidateResult / Operation / OfferResponse / Offer /
 * Money / SettlementMethod / HumanAction / Proof / OperationEvent; the schema is
 * authoritative for shapes, docs/contract/http-sse-contract.md for semantics).
 *
 * Per OSS-ADR-0046 these shapes live HERE in `src/protocol` — the same home as the
 * rest of the wire vocabulary (the `Scope` union, `RECEIPT_KINDS`, the SSE
 * constants) — so a shape change is one edit and drift is a red conformance run.
 * The CLI transport (`src/cli/backend/wire.ts`) re-exports this module rather than
 * hand-maintaining a parallel copy.
 *
 * This is DELIBERATELY distinct from the OSS camelCase domain types in
 * {@link ./index.ts}: the wire is snake_case, the Offer amount is a {@link WireMoney}
 * object (not a bare number), the cursor is an OPAQUE STRING (not `{sequence, token}`),
 * and the SSE events are `operation.*`. Both {@link ../cli/backend/remote.ts remote.ts}
 * (the client) and {@link ../cli/backend/mock.ts mock.ts} (the truthful in-process
 * server) consume it through the transport re-export, so neither can silently
 * re-fabricate a dialect: the SSE vocabulary in particular has exactly one definition
 * here, drift-guarded against the OpenAPI enum by `tests/cli.remote-conformance.test.ts`.
 *
 * Pure types + constants + pure decoders. ZERO runtime dependencies — the only import
 * is the intra-protocol domain types it decodes into (asserted by
 * tests/protocol.boundary.test.ts).
