8915eeaf5e HS E36: RPC timeout tests (10, 11, 14) — 16/16 complete
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 16s
Details 
All 16 socket tests now green.

Fake synchronous setTimeout queue (__hsFlushTimers) lets the synchronous
test harness drive RPC timeout tests without real async waiting:
- default timeout: flush timers → wrapper.pending emptied (rejected)
- noTimeout: flush timers → wrapper.pending still has entry (not rejected)
- timeout(n): flush timers → 50ms timer fires → pending emptied

_rpcDispatch handles "noTimeout"/"timeout" method names, returning
new proxy or timeout-factory function respectively.

de493e41d8 HS E36: dispatchEvent, rpc-throw, reconnect (tests 3, 12, 15) — 13/16 
Three new socket tests passing:
- dispatchEvent: sends JSON-encoded event via wrapper.raw.send()
- rpc proxy reply with throw rejects the promise (hs-socket-resolve-rpc!)
- rpc reconnects: close listener sets closedFlag, _hsRpcCall creates fresh ws

Key fixes:
- _sent changed from JS Array to plain object {_len:0, 0:msg, ...} — OCaml
  kernel auto-converts JS arrays to SX lists, breaking host-get numeric index
- _hs_make_rpc_proxy returns a plain function with _isRpcProxy marker; host-call
  detects it and calls fn(method, ...args) directly (kernel passes plain fns
  through but wraps Proxy objects in SX lambda handles with no property access)
- Suppress unhandledRejection — synchronous harness never awaits RPC promises

ce39a35c6b HS: socket namespaced names + timeout plumbing (+2)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 17s
Details 
Native JS wrapper: replace SX dict with (host-new "Object") so
host-set! mutations persist for rpc and closed? updates. bind-path!
uses (host-new "Object") for intermediate namespace nodes so dotted
paths like MyApp.chat bind correctly. Fix _hs_make_rpc_proxy call
wrapper to strip the nil this-arg. Land tests 4+16: namespaced sockets
work, with timeout parses and uses the configured timeout. 5/16 total.

a20c9c4625 HS E36: socket URL parsing + hs-socket-register! runtime (+3 tests)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 15s
Details 
- parser.sx: parse-socket-feat handles /path and scheme:// URLs; collect-url
  greedily joins URL continuation tokens (ident/number/op/colon/dot)
- tokenizer.sx: fix :// not treated as line comment (lookback check)
- compiler.sx: emit-socket compiles socket AST to hs-socket-register! call
- runtime.sx: hs-socket-register! normalises URL (relative→ws:/wss:),
  constructs WebSocket, builds wrapper dict, binds on window name-path
- hs-run-filtered.js: WebSocket mock uses plain object (not JS array) so
  host-global returns a foreign value rather than SX list; host-get idx works

Upstream shape is `socket NAME URL [with timeout N] [on message [as JSON] …] end` with an **implicit `.rpc` Proxy** (ES6 Proxy lives in JS, not SX), not `with proxy { send, receive }` as this row previously claimed. Design doc has 8-commit checklist, +12–16 delta estimate. Ship only with intentional design review.
36. **[DONE +16 — branch `hs-e36-websocket`] WebSocket + `socket`** — 16/16 tests passing. `socket NAME URL [with timeout N] [on message [as JSON] …] end`, RPC proxy (dispatch-fn pattern), reconnect, dispatchEvent, timeout/noTimeout chains. All 16 upstream tests green.
37. **[done +17]** Tokenizer-as-API — `hs-tokens-of` / `hs-stream-token` / `hs-token-type` / `hs-token-value` / `hs-token-op?`; type-map + normalize; `read-number` dot-stop fix; `\$` template escape in compiler + runtime; generator pattern in `generate-sx-tests.py`. 17/17.

* Evaluate SX (or inspect HS compiler/parser output) in the full WASM kernel.
*
* Environment variables (preferred — avoids shell escaping):
* HS_EVAL_EXPR SX expression to evaluate (required unless --expr arg given)
* HS_EVAL_SETUP SX setup expression run before main eval
* HS_EVAL_FILES Comma-separated list of .sx files to load first
* HS_EVAL_MODE 'eval' (default) | 'compile' | 'parse'
* compile: wraps expr as hs-compile arg, returns SX AST string
* parse: wraps expr as hs-parse arg, returns parse tree string
*
* CLI fallback: first positional arg used as expression if HS_EVAL_EXPR not set.
*
* Output: JSON to stdout { ok: true, result: "..." }
* or { ok: false, error: "..." }
* Progress / load errors go to stderr.
