Root-caused the every-request-400 fallback loop: the upstream silently requires an exact system-prompt banner (client-authenticity watermark). Bisected live against autoglm-api, isolated the 64-char marker, injected it at the shared buildSanitizedBody choke point in lib/core.js. The proxy now serves cloud 200s (streaming + non-streaming) with no WebSocket fallback. All pen-test suites pass (27/27, 10/10, 5/5, 4/4 + catalog refresh). Full study kept local in .dbg/ROOT-CAUSE-AND-STUDY.md.

map every failure once: 402 quota incl code 810000, 401 token, 404 model,
429 passthrough, 503 no token, 504 timeout, otherwise 502 with origin noted
60s negative cache answers permanently broken models instantly
fetch autoclaw model-config for credit tiers with heuristic fallback
destroy the upgraded websocket on all exit paths so failed fallbacks stop leaking connections.
serialize ring log writes behind a lockfile, isolate test-models logs.
one keep alive upstream agent with a single retry on real network errors only.
readbody drains past the cap and cuts sockets at four times the limit.
drop unused chat.send bridge exports, unify client ip on trusted proxies.
extract gateway server factory, banner, health handler, process guards.
single record helper writes exactly one observability line per request.
fallback outcomes carry a local tag, headersent guards end streams instead of crashing.
prefer_local skips doomed cloud attempts while credits are exhausted.
opus high, sonnet medium, haiku low, refreshed from remote model-config in the background.
unified fallback trigger gives anthropic 402/403/5xx parity with the openai format.
direct model ids still pass through untouched.
doctor reads remote model-config first and prints routing from the shared resolver.
test-models child writes its own request log instead of clobbering the main ring.
responses served by the local agent are now labeled as such.
readme gains the five-model table, a status code map with machine codes,
prefer_local and quota notes, and the live tier doctor description.
ci triggers on pushes to l-route now that the branch carries the work.
p5 smoke accepts any well-formed classified response instead of a fixed list.
gitignore covers isolated test request logs and ring lockfiles.
same widening p5 got: live upstream state decides which code a valid
request earns, the assertion only needs to prove the pipeline held up.
body model goes upstream without the provider prefix while the request model
header keeps the catalog id, path drops the legacy v1 segment, version bumped
to 1.17.5 with per request uuids, eaddrinuse now exits with one clear line.
isolated test ring is scanned for non local outcomes so results read
like cloud 403 then local agent, live upstream suites run continue on
error so server side gating never falsely reddens code prs, ring logs
upload as artifacts, manual dispatch enabled.

📝 Walkthrough

Walkthrough

The proxy infrastructure is centralized in lib/core.js. New OpenAI and Anthropic gateways use dynamic catalogs, classified errors, retries, request logging, and local WebSocket fallback. The CLI adds model diagnostics and testing. Tests, package metadata, documentation, and CI workflows are updated.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟠 High · up to e2153

This branch changes proxy routing and request handling, but the current code can still return successful empty responses for upstream errors, produce malformed streams, hang on connection failures, and stall all traffic during request logging. These concrete correctness and availability risks make the PR unsafe to merge until addressed.

117-129: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Cache the runtime catalog read.

getModelCatalog calls readRuntimeModels, which runs fs.readFileSync plus JSON.parse for each candidate file. Both entrypoints call getModelCatalog on every request: openai.js Line 138 and Line 206, anthropic.js Line 76 and Line 405. Each request therefore performs synchronous disk I/O on the event loop.

Add a short TTL cache so repeated requests reuse the parsed catalog.

+let _catalogCache = null;
+let _catalogReadAt = 0;
+const CATALOG_TTL_MS = 10_000;
+
 export function getModelCatalog(config) {
-  const catalog = readRuntimeModels(config);
+  if (_catalogCache && Date.now() - _catalogReadAt < CATALOG_TTL_MS) return _catalogCache;

62-70: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Refresh credit tiers after the token appears.

refreshTiers runs once at startup. If no token exists yet, Line 64 returns early and the process keeps heuristic tiers for its whole lifetime. This happens when the proxy starts before the user logs in to AutoClaw. Claude aliases then route by heuristics even after a valid token arrives.

startWatch already reloads the token on rotation. Re-run refreshTiers on that event, or refresh on an interval.

+// upgrade the heuristic tiers to the remote ranking.

In @.github/workflows/release.yml:
- Around line 13-17: Add workflow-level permissions for the release workflow,
granting only contents read access to GITHUB_TOKEN. Place the permissions
configuration alongside the workflow’s top-level settings, preserving checkout
and npm publish behavior without granting GitHub write permissions.

In `@anthropic.js`:
- Around line 524-533: Update the streaming callbacks around streamedStart and
onEnd so that onEnd emits the standard stream preamble when streamedStart is
still false, before writing content_block_stop, message_delta, and message_stop.
Preserve the existing preamble behavior for streams that receive an onChunk
event.
- Around line 668-679: Add an error listener to the non-stream upstreamRes
handling alongside the existing data and end listeners, returning an Anthropic
502 error when headers have not been sent and safely ending the response
otherwise. Reuse the streaming path’s upstream error-handling behavior and keep
the existing end-handler parsing logic unchanged.

In `@bin/cli.js`:
- Around line 100-105: Update the proxy process handling around spawn and the
readiness probe: attach an error listener to proxyProc, record the startup
failure, and make readiness polling stop immediately and report the underlying
error instead of waiting. Ensure proxyProc.kill() also runs when the model loop
is interrupted, such as Ctrl+C, by placing cleanup in the shared termination
path rather than only normal exits.

In `@lib/core.js`:
- Around line 890-951: Add a close listener to the upgraded socket in the
request flow, alongside the existing error listener, so a close before the chat
final event calls finish and reports an error immediately instead of waiting for
the timeout. Preserve normal completion when finish has already settled the
request.
- Around line 715-749: Update acquireLock and logRequest so logging never blocks
the event loop: remove the synchronous wait/retry and return promptly when
LOCK_PATH is unavailable, then skip the read-modify-write when the lock was not
acquired. Preserve releaseLock cleanup for successfully acquired locks and the
existing best-effort logging behavior.

In `@openai.js`:
- Around line 341-373: Ensure all upstream statuses at or above 400 are
classified and returned through sendClassifiedErrorOpenAI, while
shouldFallbackToLocal only controls whether local fallback is attempted. In
openai.js lines 341-373, update the status-handling flow and remove the terminal
success return for error statuses. Apply the same restructuring in anthropic.js
lines 594-624 so its success path runs only for statuses below 400.
- Around line 61-66: Update bufferSSE to decode upstream chunks with
string_decoder.StringDecoder instead of converting each chunk independently;
write each chunk through the decoder and flush the decoder’s remaining bytes
when the stream ends, preserving complete UTF-8 text across chunk boundaries.
Apply the same streaming-decoder pattern to the corresponding upstream buffering
paths in anthropic.js.

In `@README.md`:
- Around line 113-121: Update the README Options table to document the
--test-models flag and its --test alias, including their behavior. Revise the
--doctor description to state that it prefers the remote model-config, matching
the Model doctor section.

In `@tests/catalog-refresh.mjs`:
- Around line 77-78: Update the process cleanup in checkProxy so it awaits
proc’s exit after sending SIGTERM, with a bounded timeout that force-kills the
child if it does not exit; start the next entry point only after cleanup
completes.

In `@tests/pen-test-p3.mjs`:
- Around line 27-32: Update the assertions in tests/pen-test-p3.mjs lines 27-32
and tests/pen-test-p5.mjs lines 36-45 so valid requests cannot pass with the
local 400 invalid_request response; continue accepting classified upstream
failures in the permitted range, but require a non-validation result in both
tests. Use the existing status/result symbols in each test and make no unrelated
changes.

In `@tests/pen-test-p5.mjs`:
- Around line 25-30: Remove any existing JSONL_PATH before startProxy so the
assertion verifies that the current proxy run creates the file, and also delete
JSONL_PATH during test cleanup. Keep the existing polling logic unchanged.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Emit the stream preamble when the local agent produces no delta.

streamedStart becomes true only inside onChunk. If the local agent finishes without any assistant delta, onEnd runs with streamedStart still false. It then writes content_block_stop first, with no writeHead and no message_start or content_block_start. The client receives an invalid Anthropic event sequence and fails to parse the stream.

Send the preamble in onEnd when it was not sent yet.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Add an error listener to the non-stream upstream response.

This path attaches data and end listeners only. If the upstream connection resets mid-body, upstreamRes emits error with no listener. Node then throws, installProcessGuards logs an uncaught exception, and no response is ever sent. The client hangs until its own timeout.

The streaming path already handles this at Line 664.

       try {

Handle spawn failure and terminate the child on interruption.

spawn emits an error event when the child cannot start, for example when node is not on PATH. No listener is attached, so Node throws an unhandled 'error' event and the CLI crashes instead of printing the intended failure message. The readiness probe also keeps polling for 5 seconds before that.

Additionally, proxyProc.kill() runs only on the two normal exit paths. If the user presses Ctrl+C during the model loop, the orphan child keeps listening on port 19799 and the next --test-models run fails its readiness probe.

🛠️ Proposed fix
   const { spawn } = await import("child_process");
   const proxyProc = spawn("node", [path.join(__dirname, "..", "openai.js")], {
     env,
     stdio: "ignore",
     windowsHide: true,
   });
+  let spawnFailed = null;
+  proxyProc.on("error", (err) => { spawnFailed = err; });
+  const cleanup = () => { try { proxyProc.kill(); } catch (_) {} };
+  process.once("SIGINT", () => { cleanup(); process.exit(130); });

Then short-circuit the readiness wait:

   const ready = await new Promise((resolve) => {
     let tries = 0;
     const interval = setInterval(() => {
+      if (spawnFailed) { clearInterval(interval); resolve(false); return; }
       const probe = http.get({ hostname: "127.0.0.1", port: testPort, path: "/healthz" }, (res) => {

And report the cause:

   if (!ready) {
-    console.log(`  ${COLORS.RED}✗ Could not start test proxy${COLORS.RESET}\n`);
+    const why = spawnFailed ? `: ${spawnFailed.message}` : "";
+    console.log(`  ${COLORS.RED}✗ Could not start test proxy${why}${COLORS.RESET}\n`);
     proxyProc.kill();
     return;
   }

acquireLock blocks the event loop for up to 1500 ms.

Atomics.wait blocks the calling thread. On the Node main thread it stops the whole gateway, not only the current request. The fallback while (Date.now() < end) spin also blocks and burns CPU. So the comment "Synchronous sleep that doesn't starve the event loop" does not hold.

logRequest runs on the request path through record(). The PR describes running --test-models while the main proxy serves traffic, which is exactly the multi-process contention this lock handles. In that case every logged request can stall all in-flight requests for up to the 1500 ms deadline.

Prefer an append-then-compact scheme, or make the ring write async and lock-free by writing to a temp file and renaming it. A minimal change is to drop the entry instead of blocking when the lock is held.

🐛 Minimal fix: do not block the event loop
-  function acquireLock(deadlineMs = 1500) {
-    const deadline = Date.now() + deadlineMs;
-    for (;;) {
-      try {

-    }
-  }
+  // Single non-blocking attempt. A held lock means another writer is mid-write;

Both entrypoints answer upstream 404 and 429 with HTTP 200 and an empty body. Each handler branches on shouldFallbackToLocal(statusCode) to decide whether to return a classified error. That helper returns false for 404 and 429, so those two statuses skip the error branch and continue into the success path. callUpstreamWithInvalidRequestRetry already consumed the upstream body for every status >= 400 (lib/core.js Lines 655-658), so the success path streams nothing. The client receives 200 with an empty completion while the request log records the real 404 or 429.

  • openai.js#L341-L373: classify the error for every status >= 400, send sendClassifiedErrorOpenAI, and gate only the local-fallback attempt on shouldFallbackToLocal. Remove the unreachable return respondSuccess(upstreamRes) at Line 373.

Wait for the child process to exit before starting the next entry point.

checkProxy starts both entrypoints on the same port. proc.kill("SIGTERM") only sends the signal; it does not wait for proc to exit. The fixed 250 ms delay can end while the first listener is still active, causing EADDRINUSE or allowing the second probe to reach the first server. Await exit and force-kill after a bounded timeout.

Do not accept local validation failures as successful requests.

Both predicates accept status 400. A regression that rejects the valid payload before routing therefore passes these tests. Keep classified upstream failures acceptable if required, but reject the local 400 invalid_request path.

Remove the prior JSONL file before this assertion.

A previous local test run can leave test_requests.jsonl in place. In that case, existsSync(JSONL_PATH) passes even if this proxy process never writes a log.

Delete JSONL_PATH before startProxy, and remove it during cleanup.

the file, and also delete JSONL_PATH during test cleanup. Keep the existing
polling logic unchanged.

the upstream silently requires the exact app prompt banner inside the system message; without it every cloud call returns 400 invalid request no matter what headers or auth we send, so everything fell into the local websocket agent. bisected live against upstream and verified the proxy now serves cloud 200s streaming and non-streaming. details in .dbg/ROOT-CAUSE-AND-STUDY.md (local only)
