A monitor that only spoke WebSocket would +never receive an event in practice. + +`SorobanEventStream` therefore presents one streaming interface over two +interchangeable transports: + +| Transport | When it is used | Behaviour | +|---|---|---| +| `websocket` | `wsUrl` is set and reachable | Real `ws` connection, JSON-RPC `subscribeEvents` framing, ping heartbeats, exponential-backoff reconnect | +| `poll` | Default, or whenever the socket is down | Cursor-driven `getEvents` long-poll producing identical envelopes | + +The client **auto-selects and self-heals**: it prefers WebSocket, falls back to +polling so data never stops flowing, and keeps retrying the socket in the +background to upgrade when it recovers.

It also asserts the simulator emits byte-identical XDR +to the host, so the test double cannot drift. + +### Bugs found and fixed during validation + +Validation surfaced four genuine defects, each fixed and regression-tested: + +1. **Silent base64 corruption** — `Buffer.from(s,'base64')` skips invalid + characters, so malformed input decoded into plausible garbage instead of + being reported. Added strict validation + a trailing-byte check so corrupt + data always surfaces as `__undecodable`. +2. **Process crash on transport error** — Node throws on an `'error'` event with + no listener. The monitor could die *while successfully degrading* to + polling. Added a guaranteed listener and a normalizing `_emitError()`. +3. **`BigInt` broke the dashboard** — `store.recent()` rehydrated BigInt amounts + which `JSON.stringify` cannot serialize, 500-ing `/api/events` and silently + killing the WebSocket `hello` frame. Fixed at the boundary (JSON-safe by + default, opt-in `{hydrate:true}`) plus a BigInt-aware replacer as a net. +4. **Faulty test helper** — `events.once()` auto-rejects on `'error'`, failing a + test for behaviour that was actually correct.
