-- Initial reference SDK release aligned with ARCP protocol v1.0 (see README status).
-
+- `Arcp::Envelope` per spec §5.1 (arcp, id, type, session_id, trace_id, job_id, event_seq, payload).
+- `Arcp::Client` with session handshake, `submit_job`, `subscribe_job`, `cancel_job`, `get_result`, `list_jobs`, `ack`, `close`.
+- `Arcp::Runtime::Runtime` with agent registry, job manager, lease manager, subscription manager, event log.
+- `Arcp::Runtime::JobContext` with `progress`, `log`, `metric`, `status`, `tool_call`, `tool_result`, `stream_result`, `finish`, `fail!`, `emit`.
+- Session handshake: `session.hello`, `session.welcome`, `session.bye`, `session.error` (§6.1, §6.7).
+- Capability negotiation via `Arcp::Session::CapabilitySet` and `Arcp::Session::Feature` constants (§6.2).
+- Heartbeat with `session.ping` / `session.pong` (§6.4).
+- Application-level ack with `session.ack` (§6.5).
+- Cursored `session.list_jobs` / `session.jobs` (§6.6).
+- Resume token and `last_event_seq` replay (§6.3).
+- Agent versioning with `name@version` refs and `AgentInventory.resolve` (§7.5).
+- Cross-session `job.subscribe` with history replay (§7.6).
+- `result_chunk` event kind with `result_id` terminator (§8.4).
+- All ten standard event kinds: progress, result_chunk, log, thought, tool_call, tool_result, status, metric, trace_span, delegate (§8.2).
+- Lease subsetting with capability/expires_at/budget bounds (§9, §10).
+- `cost.budget` capability using `BigDecimal` arithmetic (§9.6).
+- Trace context propagation via Fiber-local `Arcp::Trace::Context` (§11).
+- Transports: `MemoryTransport`, `WebSocketTransport`, `StdioTransport`.
+- 15 wire error codes mapped to `Arcp::Errors::*` subclasses (§12).
+- Pluggable `Arcp::Auth::AuthScheme` with bundled `Bearer` verifier.
+- Vendor extension namespace via `x-vendor.*` event kinds (§15).
