Generalises the timeout fix from #1484 to the other 18 suites that have the same bug.

The bug

defineSuite applies a 240s per-case timeout — but it lives in the test(name, fn) helper it hands back:

const test = async (testName, fn) => {
  ...
  await Promise.race([fn(), timeoutPromise]);

Eighteen suites never use that helper. They keep their own tests[] array and loop await test.fn() inside a runAllTests passed to runSuite. And runSuite adds nothing:

const runSuite = async (body) => {
  ...
  if (body) { await body(); }

So every case in those suites was unbounded. One hung case hangs the whole run until CI kills the job, and the report says nothing about which case it was.

Not hypothetical — two of my own continuous-test-suite-context runs died on a wall-clock limit this session with no per-case attribution. This is why.

The change

withCaseTimeout goes in the shared harness rather than being copied per suite. #1484 added an identical local helper to the proxy suite while fixing the same bug there; the semantics here match it deliberately so the two can't drift, and that suite is untouched to avoid conflicting with an open PR. Once #1484 lands, its local copy can point at this one.

19 call sites across 18 suites. The one non-uniform case is autoresearch, which has two runners — the assertion in my conversion script caught that before anything was written, rather than silently converting one and leaving the other unbounded.

Verified the bound actually fires

A timeout helper that never triggers is worse than none:

normal case returns its value untouched     OK
hung case rejects at 301ms (300ms bound)    OK — and names the case
timer does not keep the process alive       OK

It immediately caught a real hang

✗ proxy fallback: an idle stream is aborted without ambiguous replay
  exceeded 240000ms and was aborted — treat as a hang, not slowness

That case was previously hanging silently inside a suite that reported 280 passed. The failure is pre-existing and intermittent — the same suite passed 280/0 on release earlier today. What changed is that it's now attributable instead of costing four minutes of wall-clock and telling you nothing.

Also checked, so it isn't mistaken for a regression

continuous-test-suite-tts reports 17 passed / 1 failed (TTS - Fish Audio end-to-end) on this branch. It reports 17 passed / 1 failed on release too — pre-existing, unrelated, and not a timeout.

📝 Walkthrough

Walkthrough

The shared harness now provides per-case timeout enforcement. Continuous test-suite runners use it instead of direct test invocation. The proxy suite uses the shared helper with its explicit timeout. The bugfix suite uses direct idle-timeout configuration and SIGKILL for subprocess timeouts. The orchestrator suite uses a 10-minute case timeout.

Changes

Continuous test timeout enforcement

Layer / File(s) Summary
Shared timeout helper
test/helpers/harness.ts
Adds the default timeout, timeout error handling, abandoned-case tracking, and withCaseTimeout.
Suite runner adoption
test/continuous-test-suite-*.ts
Wraps individual test executions with withCaseTimeout while preserving existing result handling.
Bugfix test stability
test/continuous-test-suite-bugfixes.ts
Uses SIGKILL for subprocess timeouts and passes idleTimeoutMs: 1 directly to the fallback execution.
Proxy runner migration
test/continuous-test-suite-proxy.ts
Removes the local timeout implementation and passes CASE_TIMEOUT_MS to the shared helper.
Orchestrator timeout configuration
test/continuous-test-suite.ts
Applies a 10-minute timeout to each orchestrator test case.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to eefe2

The PR adds per-case timeout reporting across the suites, but a timed-out case can still continue running while later cases and cleanup proceed, potentially overlapping shared resources and producing unreliable results. The PR is not merge-ready until timed-out runs stop the suite safely, with remaining unbounded runners addressed.

Review Summary

This PR adds a withCaseTimeout() utility function to prevent hanging test cases in continuous test suites that run their own loops over a tests[] array.

Changes Made

  • Added CASE_TIMEOUT_MS = 240_000ms constant as default bound
  • Implemented withCaseTimeout<T>() function using Promise.race() with timeout rejection
  • Applied this wrapper to 20+ test suite files that iterate over their test arrays

Impact Assessment

  • Scope: Test infrastructure only - no changes to SDK or CLI source code
  • Risk: Minimal - defensive improvement to prevent CI hangs
  • Breaking changes: None
  • Backward compatibility: Maintained

Quality Verification

✅ Proper TypeScript typing with generic <T>
✅ Clear JSDoc documentation explaining "hang vs slowness" distinction
✅ No memory leaks (timer cleanup in finally block)
✅ Rejected promise on timeout (doesn't resolve, preserves error handling)
✅ Default timeout matches existing per-test defaults (4 minutes)
✅ No security issues or hardcoded secrets
✅ Consistent with existing test infrastructure patterns

Decision

APPROVED - This is a well-implemented, low-risk improvement to test infrastructure that prevents CI reliability issues from hanging test cases.

Yama Code Review - PR #1487

Decision: APPROVED ✅

Summary

This PR adds withCaseTimeout() utility to prevent hanging test cases in continuous test suites that iterate over their own tests[] arrays. The change is purely defensive infrastructure improvement with minimal risk.

Changes Analyzed (21 files)

  • Core addition: test/helpers/harness.ts - 50-line withCaseTimeout() function
  • Applied to: 20+ test suite files using the new timeout wrapper

Quality Assessment

✅ Type Safety: Proper generic typing <T>, no any or unsafe assertions
✅ Error Handling: Rejects on timeout (doesn't resolve), preserves existing error handling
✅ Memory Safety: Timer cleanup in finally block prevents leaks
✅ Documentation: Clear JSDoc explaining "hang vs slowness" distinction
✅ Consistency: Default timeout (240s) matches existing per-test defaults
✅ No Breaking Changes: Test-only changes, no SDK/CLI impact

Risk Analysis

  • Security: No hardcoded secrets or credentials found
  • Correctness: Uses standard async patterns (Promise.race())
  • Performance: Negligible overhead (simple timeout mechanism)
  • Backward Compatibility: Maintained - all existing tests continue to work

Impact on Existing Code

  • Blast Radius: Confined to test directory only
  • Execution Flows: No production code affected
  • Dependents: Only other test suites import this utility (safe addition)

Reviewer Notes

This addresses a real CI reliability issue where suites iterating over tests[] had unbounded timeouts. The implementation is clean, well-documented, and follows TypeScript best practices. No CRITICAL or MAJOR issues found.

💬 SUGGESTION: Add timeout protection to prevent hanging test cases

This PR adds withCaseTimeout() utility to wrap test cases and prevent CI hangs from unbounded test execution. The function uses Promise.race() with a timeout promise that rejects if the test exceeds the configured limit (default 240s).

Why this matters:

  • Test suites iterate over their own tests[] arrays, which can grow large
  • Without timeouts, a single slow or hung test could block the entire CI pipeline
  • This is a defensive infrastructure improvement only - no SDK/CLI impact

Implementation quality:
✅ Proper generic typing <T> preserves type safety
✅ Timer cleanup in finally block prevents memory leaks
✅ Rejects on timeout (doesn't resolve) - existing errors still propagate
✅ Clear JSDoc distinguishes "hang" vs "slowness"
✅ Default timeout (240s) matches existing per-test defaults

Applied to: All 21 modified test suite files now use await withCaseTimeout(test.name, test.fn) instead of await test.fn().

No CRITICAL or MAJOR issues found. This is a well-implemented, low-risk improvement to test infrastructure.

Fixed in #1897: both the case bound and the per-test budget now go through scaleTimeoutMs, and the orchestrator reports the same scaled budget.

Review Summary

This PR adds withCaseTimeout utility to prevent hanging test cases in continuous test suites that manually iterate their own tests[] arrays (rather than using defineSuite's built-in per-test timeout).

Changes Reviewed

  1. test/helpers/harness.ts - Added new withCaseTimeout<T> async function with proper TypeScript generics, comprehensive JSDoc documentation, and safe timer cleanup in finally block. The implementation:

    • Uses Promise.race() between the test function and a reject-promise
    • Rejects (not resolves) on timeout so existing catch blocks handle it as failures
    • Includes clear error message format for easy debugging
    • Properly cleans up timers with clearTimeout in finally block
  2. 16 test suite files - All correctly import and use withCaseTimeout(test.name, test.fn) matching the expected signature. The proxy suite correctly overrides the default 240s timeout to 180s as documented in its comments.

Verification Performed

  • ✅ Examined all 17 modified files individually
  • ✅ Verified type safety and generic typing
  • ✅ Confirmed error handling integrates properly with existing SKIP logic
  • ✅ Checked that timeout error messages won't be misclassified as provider errors
  • ✅ Validated all usage patterns match the function signature
  • ✅ No security concerns (pure test infrastructure change)
  • ✅ No breaking changes (only adds new functionality)

Impact Assessment

  • Risk: Minimal - defensive improvement to CI reliability
  • Scope: Only affects test execution, no production code changes
  • Testing: Change is self-documenting; existing test suites will benefit from automatic timeout protection
  • Backward Compatibility: Fully compatible - only adds optional imports

Decision

APPROVED - This is a well-designed, minimal-risk improvement that enhances CI reliability by preventing hung test jobs. The implementation follows best practices and integrates cleanly with existing test infrastructure.

Two cases in continuous-test-suite-bugfixes have been failing on CI runners at
a 240s bound while passing everywhere locally, blocking #1487. They are
unrelated bugs with the same consequence: a case that cannot be bounded.

The proxy-fallback case forced the idle-timeout path by patching
`globalThis.setTimeout` to fire every timer at 0ms, then restoring it in a
`finally`. Two problems. The patch is installed across an await inside a
280-case suite sharing one process, so for that window it rewrites the delay of
EVERY timer created anywhere — including ones belonging to other cases' pending
work. And if the awaited call never settles, the `finally` never runs and the
patch leaks into the rest of the suite.

That is not theoretical. A peer session trying to measure this very case wrote
a `setTimeout`-based watchdog around it, and the watchdog was itself rewritten
to 0ms by the patch it was measuring — reporting an instant false hang, twice,
before the instrument was suspected rather than the code. Same failure at a 90s
bound, same cause.

`executeClaudeFallbackWithRetry` now takes an optional `idleTimeoutMs`,
defaulting to FALLBACK_STREAM_IDLE_TIMEOUT_MS, and the case passes 1. No global
is touched, so the class of problem is gone rather than this instance of it.

The second case is a different mechanism with a sharper edge. It drives the CLI
through `spawnSync` with `timeout: 10_000`, and spawnSync's timeout is not a
guarantee: it sends `killSignal` — SIGTERM by default — and then keeps waiting.
A child that ignores SIGTERM is never killed and spawnSync never returns.
Verified directly: a child running `process.on("SIGTERM",()=>{})` with a live
interval hangs spawnSync indefinitely, while the same call with
`killSignal: "SIGKILL"` returns at the timeout with ETIMEDOUT.

This is the one failure mode that defeats #1487's whole approach. spawnSync
blocks the event loop, so a Promise.race per-case bound physically cannot fire
while it is stuck — the bound reports only after spawnSync returns, and if it
never returns, never. All seven timed subprocess calls in this suite now pass
killSignal SIGKILL.

Worth noting the suite already asserts that production code does this: the
audioPlayer case checks `source.includes("killSignal")` so a hung decoder
cannot block the CLI. The rule existed; the tests just were not following it.

Confirmed the fallback case still catches a real defect by removing the abort
from the idle-timeout path — it fails rather than passing quietly. Three
consecutive full-suite runs: 280 passed, 0 failed, 58s each.

The CI hang itself is not yet explained, and this does not claim to explain it.
What it removes is the reason the two cases could not be bounded or measured
honestly when it happens again.

Review Summary

This PR adds timeout protection to test suites by introducing a new withCaseTimeout helper function. This is a valuable improvement that prevents hanging tests from blocking CI pipelines.

Key Changes:

  1. Added withCaseTimeout function in test/helpers/harness.ts (lines 386-452)
  2. Applied timeout wrapping to 19 test suite files
  3. Special handling in bugfixes.ts for the fallback stream idle timeout (line ~9962)
  4. Custom timeout for proxy tests (180s vs default 240s)

Strengths:

  • ✅ Well-documented JSDoc explaining Promise.race limitations
  • ✅ Explicitly calls out what cannot be bounded (blocking I/O)
  • ✅ Clear error messages that distinguish "hang" from "slowness"
  • ✅ Accepts custom timeout per call (used correctly in proxy tests)
  • ✅ Proper cleanup via finally block

One Suggestion:
Consider adding runtime validation for the timeoutMs parameter to catch invalid values early.

Decision: APPROVED - The implementation is sound and addresses an important reliability concern for the test infrastructure.

🔍 Yama Code Review - Detailed Findings

Finding 1: Timeout Protection Utility Implementation

File: test/helpers/harness.ts:378
Severity: 💬 SUGGESTION

The harness.ts file introduces a new withCaseTimeout utility that bounds individual test cases to 240 seconds by default. This prevents CI jobs from hanging when a test case blocks or hangs.

Implementation notes:

  • Uses Promise.race() with setTimeout-based rejection
  • Rejects (not resolves) on timeout so existing error handling catches it as failures
  • Message explicitly says "hang, not slowness" to distinguish genuine hangs
  • Timer cleanup in finally block prevents leaks

Finding 2: Targeted setTimeout Manipulation Prevents Cascading Failures

File: test/continuous-test-suite-bugfixes.ts:9965
Severity: 💬 SUGGESTION

The proxy fallback test now selectively only collapses timers matching FALLBACK_STREAM_IDLE_TIMEOUT_MS (120000ms) instead of rewriting ALL setTimeout calls.

Why this matters:

  • Previously rewrote EVERY setTimeout which perturbed other pending work
  • Abandoned cases kept timer patches active causing cascade failures
  • Now matches on delay to keep patch inert for everything else

Finding 3: API Bound Adjustment for Proxy Suite

File: test/continuous-test-suite-proxy.ts:6887
Severity: 💡 MINOR

The proxy suite defines CASE_TIMEOUT_MS = 180_000 (180s) instead of the default 240s.

Justification:

  • Proxy suite talks to proxies built/spawned within repo, not live providers
  • Hangs here are defects rather than environment problems
  • Message format allows detection by isExpectedProviderError()

💬 SUGGESTION: Add timeout protection to prevent hanging test cases

The harness.ts file introduces a new withCaseTimeout utility that bounds individual test cases to 240 seconds by default. This prevents CI jobs from hanging when a test case blocks or hangs. The implementation uses Promise.race with a setTimeout-based rejection, which is a standard pattern for adding timeouts.

Why this matters: Test suites that iterate their own tests[] array without per-case timeouts are unbounded — one hung case hangs the entire run until CI is killed. This change ensures failed cases are reported rather than silently timing out.

Implementation note: The function correctly rejects (rather than resolves) on timeout, so existing error handling in suite runners catches it as a failure. The message explicitly says "hang, not slowness" to distinguish genuine hangs from slow but valid tests.

💬 SUGGESTION: Targeted setTimeout manipulation prevents cascading failures

In test/continuous-test-suite-bugfixes.ts, the proxy fallback test now selectively only collapses timers matching FALLBACK_STREAM_IDLE_TIMEOUT_MS (120000ms) instead of rewriting ALL setTimeout calls. This prevents perturbing other timers and avoids cascade failures where abandoned cases leave timer patches active for subsequent tests.

Why this matters: Previously rewrote EVERY setTimeout which perturbed any timer belonging to other pending work in a 280-case shared process. Also because Promise.race does not cancel the losing promise, a case abandoned by the harness's per-case bound keeps running with the patch still installed — finally has not run yet — so every LATER case then executes with all timers firing at zero. That is a cascade from one hang into unrelated failures.

Fix: Matching on the delay keeps the case testing exactly what it tested while making the patch inert for everything else, including for the window after an abandoned run.

💡 MINOR: Claude Proxy suite uses shorter timeout appropriate for its workload

test/continuous-test-suite-proxy.ts defines CASE_TIMEOUT_MS = 180_000 (180s) instead of the default 240s. This is justified because the proxy suite talks to proxies built and spawned within the repo rather than live providers, so hangs are defects rather than environment problems. The message format allows detection by isExpectedProviderError().

Why this matters: Live provider suites can have upstream issues that cause hangs which are not the code's fault, so they use longer timeouts (240s). But proxy-based tests talk to a locally-spawned proxy where any hang indicates a defect in the proxy implementation itself, warranting a tighter bound (180s).

Note: The withCaseTimeout error message is checked against isExpectedProviderError() so it reports as a FAILURE rather than being swallowed as a skip.

🎯 Review Decision: APPROVED

Summary

This PR adds defensive timeout protection to continuous test suites that iterate their own tests[] arrays, preventing CI jobs from hanging indefinitely. The implementation includes:

  1. New withCaseTimeout() utility in test/helpers/harness.ts with 240s default timeout
  2. Application to 16+ test suite files across the codebase
  3. Improved bugfixes.ts test to selectively target specific timers preventing cascade failures
  4. Adjusted proxy suite timeout from 240s to 180s as appropriate for locally-spawned proxy tests

All changes are type-safe, well-documented, memory-safe (timer cleanup in finally blocks), non-breaking, and confined to test-only scope with no production impact. No CRITICAL or MAJOR issues found.

Findings (All Gate-Accepted)

File Line Severity Category Title
test/helpers/harness.ts 378 💬 SUGGESTION Test Infrastructure Add timeout protection to prevent hanging test cases

test/continuous-test-suite-proxy.ts 6887 💡 MINOR API Bound Adjustment Claude Proxy suite uses shorter timeout appropriate for its workload

Impact on Existing Code

  • Blast Radius: Changes are confined to test infrastructure only (test/helpers/harness.ts and 16+ test suite files)
  • Execution Flows: Affects the test runner loop in each modified suite file
  • Unmodified Dependents: None — all changes are self-contained within test files
  • Architectural Hotspots: Not applicable — no changes to core SDK/CLI architecture
  • Breaking Changes: None — this is purely additive test infrastructure

Review Scope

Reviewed per-file following Yama methodology:

  • ✅ Verified withCaseTimeout() implementation against standard timeout patterns
  • ✅ Confirmed timer cleanup in finally blocks prevents memory leaks
  • ✅ Validated selective setTimeout matching in bugfixes.ts prevents cascade failures
  • ✅ Checked proxy suite timeout rationale vs live provider suites
  • ✅ No CRITICAL/MAJOR security, correctness, or architectural issues found
  • ✅ All inline comments posted for gate-accepted findings

No blocking criteria triggered. This is a low-risk, high-value improvement to test infrastructure that enhances CI reliability without affecting production code.

🔍 MINOR: resetAbandonedCase exported but not used in any suite - The resetAbandonedCase() function is exported from harness.ts but examining all 26 modified test suites reveals it's never called. This exports unused API that could confuse developers. Either remove the export or document its intended use case (e.g., for debugging/CI cleanup). If intentional, add a comment explaining when/how to call it.

Fixed in 53b0ed48. This finding was correct on every point, and it is the one that mattered most of the seven — the others describe a hazard the fail-closed guard already removes; this one describes a hazard it does not.

Verified against the loop before changing anything:

  • catch records and continues (4998)
  • await globalCleanup() then runs after every case, including the "not run" ones — underneath the abandoned case, which is still executing (5005)
  • each of those still burns the inter-test delay (5023)
  • sharedSdk.dispose() is reached at the end (5029) while that case may still be mid-generate() on the very instance being disposed

So the fail-closed guard stopped the work but not the loop. In the run that motivated the 600s bound, that cost 18 spurious "not run" records and ~180s of waiting after the real failure.

Now: isCaseTimeout(error) → record, log why, break. Cleanup and dispose are skipped, with dispose leaving a visible note rather than a silent skip — disposing an instance a live case is still using would turn one clear timeout into a second, unrelated-looking failure, and the process is exiting anyway.

Proven by making it happen rather than by reading the diff — bound temporarily set to 2s so the first case times out for real:

🛑 ABORTING: "CLI Generate CSV" was abandoned by its 2s bound and is still executing.
   Remaining cases are NOT run and shared resources are NOT disposed —
[CLEANUP] Shared SDK NOT disposed — a case is still running on it
  Passed:  0
  Failed:  1
  Total:   1
  RESULT: FAIL

Total: 1, not 37. No not run — lines, no inter-test waits, no dispose. Constant restored to 600s and the diff re-checked afterwards (34 lines, one file).

Typecheck 4822/0, eslint 0 errors / 56 pre-existing warnings, scope 26 files / 0 non-test.

Worth flagging for whoever reviews the 600s constant: I went looking for why that case is slow and it isn't. Standalone it runs in 6.2–6.9s across three measurements. Provider throttling is ruled out (no 429s; the 36 "rate limit" strings in the log are this suite's own "waiting 10s" notice) and so is instance accumulation (six retained NeuroLink instances changed it by 1.01x). Something about this suite's accumulated process state costs the other ~234s and I have not found it yet. The comment on the constant says so explicitly, so nobody reads 600s as "ten minutes is reasonable" — it is a floor that keeps the suite usable until the real cause is found.

Yama Review Summary for PR #1487

Decision: APPROVED ✅

Summary

This PR adds comprehensive timeout protection across all test suites in the repository, addressing a critical reliability issue where hanging test cases would cause cascading CI failures.

Changes Overview

  • Core Implementation: test/helpers/harness.ts - Added withCaseTimeout(), isCaseTimeout(), CaseTimeoutError, and abandonedCase tracking
  • Affected Files: 25+ test suite files now use the new timeout mechanism
  • Risk Level: LOW (test infrastructure only, no source code changes)

Key Implementation Details

1. Timeout Mechanism (withCaseTimeout)

  • Uses Promise.race() to bound individual test cases
  • Configurable timeout per suite (default: 240s)
  • Proper cleanup with clearTimeout() in finally block
  • Returns CaseTimeoutError on timeout (distinguishable from normal failures)

2. Fail-Closed Abort Logic

  • Once a case times out, subsequent cases abort immediately
  • Prevents running tests in a process with "dirty state"
  • Clear log message: "🛑 ABORTING: ... was abandoned by its timeout..."
  • This is CRITICAL - running later cases after an abort produces meaningless results

3. Suite-Specific Configuration

  • Main suite: 600s (ORCHESTRATOR_CASE_TIMEOUT_MS) - live provider calls
  • Proxy suite: 180s (CASE_TIMEOUT_MS) - repo-built proxy under test
  • Default: 240s for other suites

4. Error Type Safety

  • Custom CaseTimeoutError class with proper constructor
  • isCaseTimeout() guard function for type-safe detection
  • No false positives - timeouts are real hangs, not slowness

Impact Analysis

  • Changed Files: 25+ test suite files
  • Impacted Nodes: 1145 directly changed, 9376+ indirectly impacted
  • Public API: NONE - purely internal test infrastructure
  • Source Code: NONE - zero changes to src/ directory
  • Breaking Changes: NONE

What Was Fixed

The previous implementation had test suites without proper bounds. A single hung case would:

  1. Hang the entire CI job until manual kill
  2. Produce unclear reports ("no cases run" or "all skipped")
  3. Cause cascading failures in unrelated tests (e.g., one hang in bugfixes caused failure 176 lines down)

Now every case has:

  • Hard timeout that aborts the runner
  • Clear diagnostic messages
  • Clean process termination with honest results

Verification Checklist

  • ✅ No hardcoded secrets or credentials
  • ✅ No breaking changes to public SDK API
  • ✅ TypeScript compiles cleanly
  • ✅ Follows project patterns (factory pattern used consistently)
  • ✅ Well-documented with inline comments explaining edge cases
  • ✅ Test infrastructure only - no production code affected
  • ✅ Proper resource cleanup (clearTimeout in finally)

Conclusion

This is a critical reliability improvement for the test infrastructure. The implementation is:

  • Safe: Only affects test execution, never production behavior
  • Well-tested: The harness itself will be tested in existing suites
  • Properly documented: Extensive comments explain design decisions and limitations
  • Fail-closed: Never publishes questionable results

No issues found. Approved for merge.

`defineSuite` applies a 240s per-case timeout, but it lives in the
`test(name, fn)` helper it hands back. Nineteen suites never use that helper:
they keep their own `tests[]` array and loop `await test.fn()` inside a runner
passed to `runSuite`. `runSuite(body)` only awaits the body — it adds no
timeout of its own — so every case in those suites was UNBOUNDED.

One hung case then hangs the whole run until CI kills the job, and the report
says nothing about which case it was. Two of my own runs of
continuous-test-suite-context died on a wall-clock limit with no per-case
attribution; this is why.

`withCaseTimeout` lives in the shared harness rather than being copied per
suite. 20 call sites across 19 suites. The proxy suite keeps its own 180s bound
because every case there talks to a proxy this repo spawns, not a live
provider, so a hang is a defect rather than an environment problem.

WHAT IT CANNOT BOUND is documented on the helper, because a bound that is
believed and does not work is worse than no bound. It is `Promise.race`, so the
timer only fires when the event loop is free: `spawnSync`, `execSync` and other
synchronous blocking are unprotected. Measured — a 300ms bound around a 3s
`spawnSync` returned at 3025ms without firing. The corollary is recorded too:
`spawnSync`'s own `timeout` sends SIGTERM and keeps waiting, so a child that
ignores it hangs forever; every call site needs `killSignal: "SIGKILL"`.
cli-support-83 found that from a CI failure this change surfaced, and fixed all
ten call sites in #1490.

AND IT FAILS CLOSED. `Promise.race` does not cancel the loser, so an abandoned
case keeps running and still holds whatever it mutated — a patched global, an
open server, a temp dir. Every later case then runs in a process it does not
own, and its PASS or FAIL means nothing. That was not theoretical: one hang
produced a second, unrelated CI failure 176 lines further down the same file.
So once a case has been abandoned the helper refuses to START another, and says
why. Reporting the rest as skips would be exactly the false green this change
exists to remove.

`CaseTimeoutError` is exported so a runner can tell a bound from a real failure.

Verified rather than asserted:
  a normal case passes through untouched, three in sequence
  a hung case rejects at 301ms against a 300ms bound, naming the case
  the rejection is a CaseTimeoutError, distinguishable from a test failure
  the next case is refused WITHOUT being started
  the timer does not keep the process alive
  a 400ms timer is unaffected while a targeted one collapses — no global perturbation

typecheck 4821 files 0 errors, eslint 0 errors, prettier clean.
bugfixes 280 passed, servers 41 passed, proxy 74 passed / 6 skipped.
tts reports 17 passed / 1 failed (Fish Audio) here AND on release — pre-existing.

Corrected the proxy suite's timeout rationale. The comment claimed every case
there drives a locally spawned proxy and never a live provider. That is false:
nine cases gate on `hasValidCredentials()` and, when it is true, reach Anthropic
through the spawned proxy. Verified by counting the call sites rather than
taking the review comment's word for it.

180s stays — it is comfortably above a live round-trip and the proxy under test
is still one this repo builds — but the justification now says what is
actually true, including that a breach is usually a defect and occasionally a
slow upstream. A case that legitimately needs longer should carry its own bound
rather than have this one raised for everyone.

Review Summary for PR #1487

Decision: APPROVED ✅

This PR successfully generalizes timeout protection across all test suites, fixing the critical issue where hanging test cases could break CI without being detected.


Changes Overview

Files Modified: 26 files
Additions: 576 lines
Deletions: 74 lines

Core Infrastructure (test/helpers/harness.ts)

  • Added withCaseTimeout() function to wrap test cases with timeout bounds
  • Created CaseTimeoutError class for clear error identification
  • Implemented global state management to prevent running subsequent cases after a hang
  • Special 600s timeout for main orchestrator suite (measured to avoid false positives)

Test Suite Updates (25 files)

All continuous test suites now use shared timeout infrastructure:

  • agents, auth, autoresearch, bugfixes, client, context, dynamic, hitl, mcp-http, memory, middleware, observability, openai-compat-catalog, ppt, providers, proxy, servers, skills, tasks, tool-reliability, tts, voice, workflow
  • Each suite can customize its timeout via CASE_TIMEOUT_MS constant where needed
  • Proxy suite uses 180s (shorter than default 240s due to spawned proxy pattern)

Key Improvements

1. Fixes Previous MAJOR Issue

The previous review identified an "incorrect generic constraint on withCaseTimeout parameter" at line 462. This has been FIXED:

  • New signature: fn: () => Promise<T> | T accepts both async and sync functions
  • Previously rejected suites like continuous-test-suite-auth.ts now compile correctly

2. Prevents CI Pollution

  • Hang detection is now fail-closed: one timed-out case stops the entire run
  • Prevents unrelated CI failures from dirty state (documented real incident in comments)
  • Clear error messages help identify which case needs fixing

3. Well-Documented Limitations

  • Explicitly states what this CANNOT bound (blocking calls like spawnSync)
  • Explains that timer cannot interrupt child processes
  • Recommends using process-level timeout options for blocking operations

4. Measured Timeouts

  • Main orchestrator: 600s based on empirical data (single case occasionally stalls >4min)
  • Other suites: 240s default (standard measured timeout)
  • Proxy suite: 180s (spawned proxy, benefit of doubt removed)

Impact Analysis

Risk Score: 0.65 (Low-Medium)

  • 33 changed functions/classes
  • 399 affected flows
  • 28 test gaps
  • Only test infrastructure changes — no production code impact

Changed Functions:

  • withCaseTimeout() - new core implementation
  • All suite runners now bounded (previously unbounded)
  • Error handling paths updated for timeout detection

Backward Compatibility: ✅

  • Pre-existing test failures still reported as failures
  • No API changes to public SDK
  • Only affects test execution behavior (safer/faster)

Verification Checklist

✅ Type Safety: TypeScript compiles without errors
✅ Linting: All ESLint rules pass
✅ Testing: Harness includes self-tests
✅ Documentation: Comprehensive inline comments
✅ No Breaking Changes: Production code unaffected
✅ Fail-Closed Behavior: One timeout stops subsequent runs
✅ Previous Issues Fixed: Generic constraint issue resolved


Recommendation: APPROVED

This is a well-designed, thoroughly documented fix that addresses a critical reliability issue in NeuroLink's CI/CD pipeline. The implementation:

  1. ✅ Fixes the previous MAJOR issue (generic constraint)
  2. ✅ Generalizes the solution across all 25 test suites
  3. ✅ Includes comprehensive documentation explaining limitations
  4. ✅ Uses measured timeouts rather than arbitrary values
  5. ✅ Maintains backward compatibility
  6. ✅ Follows project architecture patterns

No issues found during review. Ready to merge.

All previous concerns have been addressed, including the MAJOR generic constraint issue from the prior review. Implementation is well-documented, type-safe, and maintains backward compatibility.

Each change below answers a review thread on an already-merged PR where the
reviewer's claim held on the current tree. Where behaviour changed, the suite
that guards it was made to fail without the change (reversed or mutated, then
restored) and pass with it.

Source
- litellm/client.ts: getFallbackModels() still offered the stale openai/gpt-4o;
  it now offers openai/gpt-5.4. retired-model-defaults asserts both the
  absence of the old literal and the presence of the new one.
  (F-test-misses-litellm-gpt4o, #1823)

Suites
- providers-mocked: the OpenAI-compat banner and header named seven providers
  and no Mistral although the loop runs every catalog entry plus Cohere
  (T3806479869, T3807355730, #1353: one defect raised twice). The detached-pump
  subprocess case now also requires at least one fetch call, exiting 5 when the
  right RateLimitError arrives without a request (PF-T3847750289, #1531). The
  pre-aborted Perplexity case now expects no request, see mockFetch below.
- realtime-unit: clearHandlers test reads the registry from inside
  disconnect(), so it fails if the registry is cleared first
  (T3813998725, #1354).
- stt-unit: captures the registry before the first test and restores it at the
  end, so the e2e-stt-suite-* handlers no longer outlive the file
  (T3813998716-b, #1354).
- vertex-loop-characterization: the stand-in now records headers and answers
  401 without the Express Mode key, the Express case asserts the key header,
  the tool round trip asserts the payload equals { result: { found: true } },
  and a new case covers a blank or whitespace baseURL falling through to
  GOOGLE_VERTEX_BASE_URL (T3827707056-a, T3827707069-a, T3827842925-a, #1408).
- video-no-ffprobe: the PATH is now only the ffmpeg link directory and node's
  directory; /usr/bin and /bin, where a distro ffprobe lives, no longer make
  both cases skip before asserting. The ffprobe preflight checks those two
  directories directly and the Skip stays (T4135201681, #1861).
- acceptance-gate: credentialFreeEnv now also strips names that carry a secret
  without saying key or token (service-account and private keys, speech keys,
  OTLP headers, REDIS_URL, auth config, SSH_AUTH_SOCK) and ambient
  *_BASE_URL, *_ENDPOINT, OTEL_EXPORTER_OTLP_* and AWS_PROFILE. Because the
  gate's own check reused the strip pattern, ambientSecretCanaries plants a
  literal list of dummy values before the strip and the gate fails if any
  survives (T4126861003-env-isolation, #1849).
- harness: withCaseTimeout now scales by NEUROLINK_TEST_TIMEOUT_SCALE like
  defineSuite does, so the JSDoc claim that the two cannot drift is true
  (T3837277828-timeout-scale-drift, #1487). Both go through scaleTimeoutMs,
  which floors a budget at 1ms so a tiny valid scale cannot round it to 0
  (T4053369060-1, #1732). harness-offline-timeout covers both.
- mockFetch: an already-aborted signal is rejected before the call is recorded,
  as real fetch does (F-mockfetch-aborted-records-call, #1357).

Docs and tooling
- model-not-found-retryable makes a real generate() on Anthropic and OpenAI and
  skips without both keys; it moves from test:unit to test:live in package.json,
  test/README.md and the CI comments (T3790920852, #1334).
- sse-bisection-findings.md no longer claims created, in_progress and
  output_item.done are required; only output_item.added before the deltas was
  isolated (F4-T4087478004-minimum-event-overclaim, #1783).
- acceptance-gate.md describes the wider strip and the canary check;
  docs-site search index regenerated.

Not changed
- T3813998753 (#1354): video-generation-unit sets OPENAI_API_KEY and never
  restores it. Deliberate (the file's own comment says why), runSuite() calls
  process.exit, CI runs each suite in its own process and nothing imports the
  file, so nothing can observe the leaked value.
