/**
 * # kestrel.markets/client — the launch-min programmatic client (kestrel-109).
 *
 * The SDK face of the "four equal faces" (http / sdk / cli / mcp — ADR-0004). A
 * small, dependency-light client for the day-one programmatic flow:
 *
 *   mint a trial capability → run a sim → stream the operation → read the
 *   proof / receipt (the certified Blotter, and the judged Grade over it).
 *
 * It speaks the SAME canonical platform contract the CLI's `RemoteBackend`
 * (`src/cli/backend/remote.ts`, post-kestrel-5rb) speaks, byte-for-byte, because
 * it decodes through the ONE shared wire dialect in `src/cli/backend/wire.ts`
 * (snake_case bodies, {@link WireMoney} Money, opaque-STRING cursor, the
 * `operation.*` SSE vocabulary). Sharing `wire.ts` is what makes drift
 * impossible: there is exactly one definition of the shapes / SSE event names,
 * pinned to the platform OpenAPI fixture by the conformance suite — this client
 * cannot re-fabricate the old divergent dialect (the failure kestrel-5rb killed).
 *
 * ## Why this is a standalone module, not a wrapper over RemoteBackend
 *
 * `RemoteBackend` implements the CLI-internal `ExecutionBackend` seam, whose
 * argument/result types (SessionArgs/EpisodeReport/FillModelName/WakeRecord/…)
 * transitively type-import `src/cli/heavy.ts` → `src/session/*` → the engine /
 * ledger tree, which value-imports `bun:sqlite` and `Bun.*`. The published
 * library is emitted by `tsconfig.build.json` with `types: []` (zero built-ins),
 * so pulling ANY of that graph into the client's emit closure fails the build.
 * `remote.ts` itself also relies on web ambient types the library build only gets
 * via the `DOM` lib. So a thin wrapper — or even a bare re-export — of
 * `RemoteBackend` is NOT buildable as a public library entry point.
 *
 * This module therefore reuses the DIALECT (`wire.ts`) and the DOMAIN types
 * (`src/protocol`) — both zero-dependency — and mirrors `remote.ts`'s HTTP/SSE
 * plumbing (deterministic Idempotency-Key, opaque-cursor SSE resume, structured
 * 402/Offer surfaced as DATA, fail-closed on unknown SSE events). It imports
 * NOTHING from `src/cli`. The public surface is clean `src/protocol` types.
 *
 * CLEANUP FOR kestrel-djm.5 (the full dual-transport SDK, POST-LAUNCH):
 *  - DONE (kestrel-bsn8): the SSE framing + opaque-cursor resume loop is no longer
 *    mirrored here — this client and `remote.ts` share the ONE library-safe transport
 *    leaf `./sse-transport.ts`; the CLI's `../cli/backend/sse.ts` is a thin adapter over
 *    the same leaf.
 *  - DONE (kestrel-z473.2): the whole platform-wire DECODE surface — `DEFAULT_API`, the
 *    Idempotency-Key, the JSON/auth headers, the trial mint, the effectful 402-gated POST,
 *    the 402/Offer decode, and the OperationEvent SSE decode/accumulate loop — is now the
 *    ONE library-safe module {@link ./platform-wire.ts}. This face is a thin adapter that
 *    supplies its {@link KestrelClientError} factories and owns caching; it no longer
 *    hand-mirrors any of the dialect, so `remote.ts` can never drift from it.
 *  - `contractMockFetch` is re-exported from `src/cli/backend/mock.ts` (the only
 *    `src/cli` coupling, and it is library-safe); relocate the mock to a neutral
 *    home (e.g. `src/client/mock.ts`) so the client owns its own test double.
 *  - Decouple `remote.ts` from `heavy.ts` so the CLI backend can itself be built
 *    on top of this client instead of the reverse.
 *
 * Determinism: no wall clock, no RNG — the Idempotency-Key is a pure sha256 of
 * the canonical request, so a replay is effect-once (ADR-0009). node ≥18 + bun +
 * Workers: web `fetch`/`ReadableStream`/`TextDecoder` only, no native deps.
