/**
 * `@nanobpm/agentic/session/acp` — the ACP ingestion backend (ADR 0062, slice 2).
 *
 * The preferred harness-facing backend of the `@nanobpm/agentic/session` contract
 * (ADR 0062 §5): an Agent Client Protocol (protocol v1) client that connects to an
 * ACP-speaking harness (`opencode acp`, `claude-code-acp`, the Gemini lineage),
 * runs the `initialize` handshake to probe `agentCapabilities.loadSession`, and
 * normalises the `session/update` stream into canonical {@link SessionEvent}s —
 * driving via `session/prompt`, steering via `session/cancel`, and **restoring**
 * prior history via `session/load`.
 *
 * Exports, in the order a consumer meets them:
 *  - {@link openAcpSession} / {@link AcpSessionClient} — the ingestion client and
 *    its capability probe / prompt-result types;
 *  - {@link classifyUpdate} + {@link ACP_FIDELITY_GAPS} — the pure wire→canonical
 *    normaliser and the enumerated ADR 0062 §5 fidelity gaps that justify slice 3;
 *  - the {@link AcpConnection} JSON-RPC peer and the {@link AcpTransport} seam,
 *    with {@link spawnAcpTransport} (a real harness subprocess) and
 *    {@link inMemoryTransportPair} (an in-memory peer for tests);
 *  - the ACP wire vocabulary ({@link ACP_METHOD}, guards) from `protocol.ts`.
