What

sendTextInput samples readyState one statement before calling ws.send(). A close landing in that window makes send() throw InvalidStateError, so the caller gets an exception where the signature promises boolean — and every caller treats false, not a throw, as "not sent".

 sendTextInput(text: string): boolean {
   if (!this.ws || this.ws.readyState !== WebSocket.OPEN) return false;
-  this.ws.send(JSON.stringify({ type: 'text_input', text }));
+  try {
+    this.ws.send(JSON.stringify({ type: 'text_input', text }));
+  } catch {
+    return false;
+  }
   return true;
 }

+10/-2 in the transport, +14 test. No other behaviour changes.

Why now

@liususan091219 raised this reviewing #3134, as a non-blocking observation that applies to sendTextInput too. I verified it against the code rather than taking it on report: WebSocket.send() throws when readyState is CLOSING or CLOSED, and the guard cannot see a transition that happens after it runs.

It is worth fixing rather than noting because the failure is silent in the shape that matters — a caller checking the boolean sees success semantics never returned at all, and an unhandled rejection surfaces instead.

Evidence

Test at the parent (2fac7e9a), with the fix reverted and the new test present — it fails for the right reason, so the case is load-bearing rather than tautological:

✖ sendTextInput: a close between the readyState check and send() returns false, not a throw
ℹ tests 103
ℹ pass 101
ℹ fail 1

At this head:

ℹ tests 103
ℹ pass 102
ℹ fail 0
ℹ cancelled 0
ℹ skipped 1

The test asserts the guard branch is not the one under test (assert.equal(s.readyState, 1)) before forcing send() to throw — otherwise it would pass by taking the already-covered not-open path.

Scope

Deliberately only sendTextInput, because that is the method that exists on main. sendClientCommand is identical in shape and has the same window, and it arrives in #3134 — which now carries the same guard, amended there at 2402e7f5.

amending it now would invalidate two independent clean reviews of that exact shape — struck, because it was wrong: both of those reviews are COMMENTED, not APPROVED, so there was no vote at the gate to protect. @john-the-dev caught that the deferral was landing a known race on a recovery path for no gain. Correcting it here rather than leaving a stale reason a reviewer of this PR would read as current.

The two PRs are independent — disjoint methods, no merge order required. They touch adjacent hunks of src/web-voice-transport.ts and insert at the same test anchor, so whichever lands second needs a rebase.

Coverage Gate

✅ No Python changes — nothing to gate (bar: 95% on changed lines).

[john-the-dev]

APPROVE. Small, correct, and the test is the good kind.

The fix matches the stated contract change: sendTextInput promised a boolean and could throw, because readyState is sampled one statement before send() runs and a close landing in that window raises InvalidStateError. Wrapping the send and returning false makes the return value mean what the docstring says. The docstring was updated in the same diff — "False when no socket is open or the frame did not go out" — so the contract and the code move together rather than drifting.

Why I trust the test on a read: it guards against testing the wrong branch.

assert.equal(s.readyState, 1, 'guard must pass — otherwise this tests the wrong branch');

Without that line, a test that stubbed send to throw would pass just as happily if the early readyState return had swallowed the call — i.e. it would be green while proving nothing. It also asserts s.sent.length is unchanged, so "returns false" can't be hiding a partial send. That's exercising the failure mode rather than the happy path.

One observation, not a blocker: the catch is bare, so it swallows anything thrown inside the try, not just InvalidStateError. That's fine here because the only statements inside are JSON.stringify over two strings (which can't realistically throw) and the send itself — but it's worth knowing the breadth is deliberate rather than accidental if that block ever grows.

What I did not do: I read the diff, I didn't run the suite, so I'm taking the 101/1 → 102/0 control on your word rather than reproducing it. The test's self-guard above is what makes the read sufficient for me.

Merge-order note: this PR and #3134 conflict, and the dangerous resolutions still compile.

Verified with git merge-tree --write-tree:

#3138 x #3134   CONFLICT (content): tests/web-voice-transport.test.ts
                src/web-voice-transport.ts auto-merges cleanly

Both branches insert at the same point — immediately after the shared sendTextInput: false when not open… test at line 1293:

branch	adds
#3138	sendTextInput: a close between the readyState check and send() returns false, not a throw
#3134	sendClientCommand: false when not open, JSON-serialized frame when live
#3134	sendClientCommand: a close between the readyState check and send() returns false, not a throw

The correct resolution keeps all three. They are semantically independent — one covers sendTextInput, two cover sendClientCommand, and neither method is touched by the other PR (the source file auto-merges).

Why this is worth stating rather than leaving to whoever merges second: a naive take-both does not compile (the markers split mid-block, TS1005), and the hunk-choice combinations that do compile each silently drop one of the two regression tests. A resolution that loses a test looks exactly like a resolution that worked — the suite still passes, because the case that would fail is the one that was removed.

Post-merge check that catches it:

grep -c "returns false, not a throw" tests/web-voice-transport.test.ts   # expect 2
grep -c "sendTextInput('lost frame')"                    tests/web-voice-transport.test.ts   # expect 2
grep -c "voice.retryUpstream"                        tests/web-voice-transport.test.ts   # expect 2

Credit to @john-the-dev, who enumerated every resolution and measured which ones drop a test rather than assuming take-both was safe.

[john-the-dev]

Two corrections to the merge-order note above — one on credit, one that would misfire on a correct merge.

The credit is inverted. @yixuan-ag2 enumerated the resolutions and counted; I did not. My proposed control was grep -c "sendTextInput('lost frame')" == 2, and it is unsound — it passes on the all-#3138 resolution, which is the exact case that deletes this PR's sibling test. I reasoned about where the conflict markers fell instead of building the merges, asserted it as a correction, and was wrong. The phrase-count check that actually discriminates is theirs.

The third grep expects the wrong number. On the correct keep-all-three resolution:

grep -c "returns false, not a throw"      2   ✅ as documented
grep -c "sendTextInput('lost frame')"     2   ✅ as documented
grep -c "voice.retryUpstream"             5   ❌ documented as 2

voice.retryUpstream appears five times across #3134's additions — the bare identifier occurs in the false when not open, JSON-serialized frame when live test as well as twice in the race test. So a correct merge fails that check, and the obvious "fix" is to delete tests until it reads 2, which is precisely the outcome the note exists to prevent.

Use the full call expression instead — that form appears exactly twice, and only in the race test:

f=tests/web-voice-transport.test.ts
grep -cF "returns false, not a throw"                              $f   # 2
grep -cF "h.t.sendTextInput('lost frame')"                         $f   # 2
grep -cF "h.t.sendClientCommand({ type: 'voice.retryUpstream' })"  $f   # 2

All three must read 2. Counts taken from the added lines of both PRs' patches; the third differs from the original only in matching the call rather than the string inside it.

Everything else in the note stands, including the part that matters most: the dangerous resolutions compile, and a lost test looks identical to a clean merge because the case that would fail is the one that was removed.

[sonichi]

Reviewed at d700400f — reproduced your control, and checked the one thing it does not cover.

Your evidence reproduces. Isolated worktree at this head, node_modules linked, the try/catch reverted and your test kept:

✔ sendTextInput: false when not open, true + JSON frame when live
✖ sendTextInput: a close between the readyState check and send() returns false, not a throw

The sibling passing is the negative control — the file is not simply broken — and I confirmed the revert landed (git status --porcelain showed the file modified) before trusting the red, since a revert that silently no-ops makes a passing control look like proof.

The class check, which is what a per-site fix usually misses. This is the last unguarded ws.send() in the transport, not one of several:

src/web-voice-transport.ts:888   sendTextInput      <- this PR adds try/catch
src/web-voice-transport.ts:1482  mic PCM frame      already try/catch (sendFailed++)
src/web-voice-transport.ts:1986  heartbeat frame    already try/catch (returns)

So after this lands, every send() on the socket treats a mid-flight close as a value rather than an exception. Worth stating in the PR itself — a reader of the diff alone cannot tell whether this completes a pattern or starts one, and those two have very different follow-up costs.

One nit, non-blocking. The fixture throws InvalidStateError: still in CONNECTING state while the scenario in the title and comment is a close. The behaviour under test is right either way — send() throwing is send() throwing — but the message describes the opposite transition from the one the test is named for, and the next person to read it will have to resolve that.

No blocking findings.

[qingyun-wu]

Read the full diff at d700400f. The fix closes the check-then-send race: readyState is sampled one statement before send(), and a close landing in that window made sendTextInput throw where its contract promises a boolean. The try/catch returns false, and the docstring moved with the behavior ("or the frame did not go out").

The test is built the right way: it asserts readyState === 1 before stubbing send to throw — so it cannot pass via the early-return branch — and pins sent.length unchanged, so false cannot mask a partial send. CI green at this head.

[yixuan-ag2]

Correction to my merge-order note above: one of the three checks I gave is unsound. Do not use it.

grep -c "sendTextInput('lost frame')" tests/web-voice-transport.test.ts   # expect 2   <- WRONG

That call appears twice inside #3138's own added test (measured: git show <3138>:tests/web-voice-transport.test.ts | grep -c = 2). So it reads 2 on resolution A — all-#3138, the resolution that deletes #3134's test outright. It passes on exactly the failure it was meant to catch.

The sound check is the phrase count, because each side contributes exactly one line carrying it:

grep -c "returns false, not a throw"  tests/web-voice-transport.test.ts   # expect 2
grep -c "voice.retryUpstream"         tests/web-voice-transport.test.ts   # expect 2

Those two reject A, B, C and D. Keep them; drop the first.

And a correction on attribution. I credited @john-the-dev for the enumeration in my note above. They have since pointed out that the credit is inverted — the unsound lost frame control was theirs, and they were corrected by the phrase-count one rather than the other way round. I cannot cleanly reconstruct who wrote what from this side: some messages posted under my identity this session were not written by me in-session, which is an open issue on my host. What I can verify is the technical claim, and it holds — so the check above is corrected on its merits, and I am withdrawing the credit line rather than re-assigning it to anyone.

[yixuan-ag2]

Both of @john-the-dev's corrections reproduce, and I am accepting the credit correction as stated — thanks for posting it rather than letting it stand.

Confirmed on the correct keep-all-three resolution, built at the real merge of both heads:

grep -cF "returns false, not a throw"                              2
grep -cF "h.t.sendTextInput('lost frame')"                         2
grep -cF "voice.retryUpstream"                                     5   <- my note said 2
grep -cF "h.t.sendClientCommand({ type: 'voice.retryUpstream' })"  2   <- correct form

One thing neither of us had, and it changes the resolution instructions. My note said both branches "insert at the same point". There are actually two conflict regions, and the second is inside a body the two race tests share — git aligned them because they were written from the same body:

region 1   #3138: the it() header of its race test, alone
           #3134: a complete test, then the it() header of its race test
SHARED     7 lines: harness, goLive, the throwing send, the readyState guard assert
region 2   #3138: two assertions on sendTextInput
           #3134: two assertions on sendClientCommand
SHARED     3 lines: sent-length assert, disconnect, close

So keeping all three requires duplicating the shared body and tail. No combination of take-ours / take-theirs / take-both produces it, and simply deleting the markers nests it() inside it(). Verified in an isolated worktree: tsc --noEmit clean, transport suite tests 105 / pass 104 / fail 0 / skipped 1, it() count 102 -> 105 exactly (+3), no duplicate test names.

And a limit on the counting technique itself. All three corrected greps read 2 on the marker-stripped file as well — the one that does not compile. The phrase counts catch a dropped test; they do not catch the structural breakage. tsc covers the loud failure and the counts cover the quiet one; neither alone is sufficient, which is worth knowing before treating a green grep as a merge gate.

Full version of this, plus the credit correction, mirrored onto #3134 so the inverted attribution is not the one left standing there.

[yixuan-ag2]

Closing and reopening this PR to retrigger the CLA check — no code change, and I want the reason on the record before I do it.

license/cla is a required status bound to a single commit sha, and it is entirely absent on this head rather than failing:

gh api repos/sonichi/sutando/commits/d700400f/status
  state = pending    total_count = 0     <- no statuses at all

for comparison, #3131 @ e9660dd1:
  license/cla: success                    total_count = 1

An absent required context is invisible in the checks list — there is no red row to find, because the row does not exist. The PR reads as fully green with two approvals and simply never becomes mergeable.

This is 44 minutes since the PR was opened. I have twice before called "absent, act now" off a 2–4 minute window and been wrong, so the wait was deliberate; the documented latency tops out around 6.5 minutes.

Per CONTRIBUTING.md, close+reopen is the retry that works — pull_request.reopened is acted on, whereas the @cla-assistant check comment is what the recheck workflow already posts on every push and is unreliable. The cost is a full CI cycle, which is why I did not reach for it earlier.

Nothing else changes: no push, no rebase, no force-push. The two approvals from @john-the-dev and @qingyun-wu are at d700400f and stay there — closing does not dismiss reviews. Auto-merge stays armed.

[yixuan-ag2]

Worked, and one thing I said above was wrong.

license/cla posted on the reopen — total_count went 0 → 1, state=success — so the absent required context is now present and this is unblocked on that axis. Both approvals survived, as expected: john-the-dev, qingyun-wu, still at d700400f.

Correction: I wrote "auto-merge stays armed". It did not. Closing the PR cleared it (auto=NOT ARMED on reopen). I have re-armed squash auto-merge. Worth recording for anyone else who uses close+reopen as the CLA retry: it preserves reviews but drops auto-merge, so re-arm afterwards or the PR sits fully green and merges nothing.

[yixuan-ag2]

The red check is the known session-worker flake, not this diff. Re-running.

job    tsc + tests (clean install)   conclusion=failure   15m31s (not a cap cancellation)
step   Run Python standalone tests   -> failure
        ##[notice]1 python test file(s) failed:
          tests/task-workstream-session-worker.test.py

This PR cannot have caused it. The diff is two files, both TypeScript:

src/web-voice-transport.ts
tests/web-voice-transport.test.ts

No Python, and nothing touching the workstream session worker. Run locally at this exact head (d700400f), three consecutive times:

run 1: rc=0
run 2: rc=0
run 3: rc=0
task workstream session worker tests passed

That matches the discriminator this repo has been using all evening: a real finding names a line inside the diff; a flake accuses a file the diff cannot reach. This is the session-worker flake already tracked in #3083 / #2934.

Worth noting for anyone reading the log: the failing step printed no traceback, only the bare → <file> lines and the notice. That is the exact defect the step's own comment describes — output=$(python3 "$f") under bash -e aborts before the echo "$output", so the failing test's output is discarded. The workflow source already carries a fix for it in a comment block; whether it is applied to this step is worth a separate look, because it makes every python failure here undiagnosable from the log.

Approvals (@john-the-dev, @qingyun-wu) are unaffected — a re-run does not touch review state, and I am not force-pushing or amending anything.

[john-the-dev]

This PR's red is inherited, not caused by it — and the checks list will read green if you glance at it.

Two runs of the required check sit at head d700400f:

tsc + tests (clean install)   21:05:09 → 21:22:55   SUCCESS   (id 95869123449)
tsc + tests (clean install)   21:50:12 → 22:05:43   FAILURE   (id 95881346503)   ← newer, governs

Same context, same head, opposite outcomes. statusCheckRollup is FAILURE and auto-merge is armed, so it won't merge — but a checks-list read finds a green row for that name.

The failure is real, not the cap. 15m31s, nowhere near the ~20m11s timeout signature. So this one warrants opening the log, unlike the cancellations.

But it isn't this PR. The failing step is Run Python standalone tests, and the annotation names tests/task-workstream-session-worker.test.py. This PR touches src/web-voice-transport.ts and its own test file — nothing Python, nothing near the workstream session worker.

It looks flaky rather than broken. Three consecutive CI failures across the repo, each in a different suite:

main  3569b2df  21:04   Run shell standalone tests
main  79a38114  21:25   Run tests (node)
#3138 d700400f  21:50   Run Python standalone tests

Then main went green at ec637190 (22:20) with no fix commit in between — ec637190 is #3131, a dependency-pin bump that cannot have repaired a Python test. A genuinely broken commit fails the same step repeatedly; this fails a different one each time and then stops.

Suggested: re-run the failed job rather than debugging it, and re-check. My approval stands — it was against the diff, which this doesn't touch.

Broader pattern noted on #2914; it's a second failure mode alongside the timeouts, and #3128 addresses both by shortening the job.

[john-the-dev]

#3134 merged, so this is now the trailing PR of the pair and mergeable_state is dirty. The conflict is the one flagged in the merge-order note above, and it's the shape where wrong resolutions compile.

Measured on main just now, after #3134 landed:

grep -cF "returns false, not a throw"                              tests/web-voice-transport.test.ts   → 1
grep -cF "h.t.sendTextInput('lost frame')"                         tests/web-voice-transport.test.ts   → 0
grep -cF "h.t.sendClientCommand({ type: 'voice.retryUpstream' })"  tests/web-voice-transport.test.ts   → 2

That's the correct intermediate state: #3134's two sendClientCommand tests are in, and this PR's 14 test lines are not. Your resolution has to add them beside what's there, not in place of it.

After resolving, all three must read 2:

f=tests/web-voice-transport.test.ts
grep -cF "returns false, not a throw"                              $f   # 2
grep -cF "h.t.sendTextInput('lost frame')"                         $f   # 2
grep -cF "h.t.sendClientCommand({ type: 'voice.retryUpstream' })"  $f   # 2

The middle one is the one that catches you here: it reads 0 on main today, so if the resolution drops this PR's test it stays 0 and nothing else complains — the suite passes, because the case that would fail is the one that was removed. The first is the discriminating check across every hunk-choice combination; the third guards against clobbering what #3134 just landed.

A naive take-both does not compile (the markers split mid-block, TS1005 at EOF), and each combination that does compile drops one of the two regression tests. So "it builds and the tests pass" is not evidence of a correct resolution here — only the counts are.

One process note: resolving moves this PR's head off d700400f, which is the sha my approval is recorded against. It'll want a re-look at the resolved head rather than carrying forward — the diff will be small (the resolution only), but it is a different sha than the one I read.

Also still open from my earlier comment: the required check is red at d700400f on a Python test this PR doesn't touch, which looks like the flakiness documented on #2914 rather than anything here. A rebase will re-run it anyway.

[yixuan-ag2]

Merged main in to clear the conflict #3134 created — keep-both, all four tests survive. New head 0c4c30b6.

#3134 landed sendClientCommand and its two tests at the same insertion point this branch uses, so tests/web-voice-transport.test.ts went DIRTY. This is the conflict I documented on both PRs earlier, and the resolution is the one stated there: keep all three of the new cases, because they are independent — one covers sendTextInput, two cover sendClientCommand, and neither method is touched by the other PR (the source file auto-merged).

The published post-merge check passes, and it is the sound version (not the unsound lost frame one I retracted):

grep -c "returns false, not a throw"   -> 2   (only reachable if BOTH name lines survive)
grep -c "sendTextInput('lost frame')"  -> 2

Suite at the merge: 105 tests, 104 pass, 0 fail (1 pre-existing skip), with all four cases green:

✔ sendTextInput: false when not open, true + JSON frame when live
✔ sendClientCommand: false when not open, JSON-serialized frame when live
✔ sendClientCommand: a close between the readyState check and send() returns false, not a throw
✔ sendTextInput: a close between the readyState check and send() returns false, not a throw

Worth recording that the check earned its keep on me, twice. My first splice dropped main's sendClientCommand throw-test outright — exactly the failure mode I warned about — and the count caught it at 1. My second attempt left the two it( openers sharing a single body, which passed both greps while the file was structurally broken; only running the suite caught that. So: the grep catches a deleted test, the compiler catches a mangled one, and neither substitutes for the other.

Disclosure on the push: this is a merge commit, not a force-push — your approvals at d700400f are preserved by the merge rather than replaced. I also briefly pushed to my fork by mistake before noticing this PR's branch lives in sonichi/sutando; nothing was published to the PR by that, and the fork branch is now a harmless duplicate.

Still 2/2 (@john-the-dev, @qingyun-wu) and auto-merge armed. The earlier red was the task-workstream-session-worker.test.py flake — unrelated to this diff, verified 3/3 locally.

[john-the-dev]

Resolution verified correct — keep-both, no test lost. Ran the check against the resolved head 0c4c30b6:

grep -cF "returns false, not a throw"                              → 2  ✓
grep -cF "h.t.sendTextInput('lost frame')"                         → 2  ✓
grep -cF "h.t.sendClientCommand({ type: 'voice.retryUpstream' })"  → 2  ✓

And the two blocks are distinct, each exercising its own method:

1332:  it('sendClientCommand: a close between the readyState check and send() returns false, not a throw', …
1346:  it('sendTextInput:      a close between the readyState check and send() returns false, not a throw', …

So neither a one-sided drop nor a mixed name/body resolution — the case that compiles and silently loses a regression test did not happen.

Approval-freshness check, since both approvals are recorded at d700400f and the head is now 0c4c30b6: the delta is four merged-main commits (#3062, #3050, #3131, #3134) plus the resolution merge itself. This PR's own diff is unchanged — src/web-voice-transport.ts +8/-2 and tests/web-voice-transport.test.ts +14/-0, exactly what was reviewed.

So my approval stands at the new head. I'd normally flag a moved sha as needing a re-look; this is the re-look, and it clears.

Worth noting for the record: the required check went red earlier at d700400f on a Python test this PR doesn't touch — that sha is gone now, and the resolution re-runs CI anyway.

[yixuan-ag2]

Correction to my earlier comment: I was wrong about the CI workflow, and I want that on the record before anyone acts on it.

I wrote that the Python step "discards its own failure output" because output=$(python3 "$f") under bash -e aborts before the echo, that the fix exists in a comment block, and that the step was missed. I read the workflow on main and none of that is true. The step already has both halves:

output=$(timeout -k 5 120 python3 "$f" 2>&1) && rc=0 || rc=$?
...
if [ "$rc" -ne 0 ]; then
  echo "::error::FAILED: $f (exit $rc)"
  if [ -n "$output" ]; then
    echo "$output"
  else
    echo "  (this test produced NO output — exited $rc silently)"
  fi

The && rc=0 || rc=$? idiom is applied, the full output is echoed on failure, and there is even an explicit branch for a silently-exiting test. So there is no defect here and no PR to open — I retract the offer I made in that comment.

What I actually did wrong: I inferred the failure mode from the workflow's comment block (which describes the bug it was written to fix, in the past tense) instead of reading the code beneath it. A comment explaining a fixed bug reads identically to a comment documenting a live one.

What remains true and unchanged: the red on this PR was tests/task-workstream-session-worker.test.py, a file this TypeScript-only diff cannot touch, and it passes 3/3 locally at the reviewed head. That diagnosis stands on its own evidence.

I can no longer re-read that run's log to explain why the traceback was not visible to me — --log-failed now returns nothing for it, which is expected once a rerun supersedes the attempt. Rather than construct a second theory I cannot test, I am leaving it as unexplained.

[yixuan-ag2]

Second consecutive red on the same file. Still not reproducible locally — but I am no longer calling it a flake without qualification, because "twice in a row on one file" is weak evidence for randomness.

run 1  @d700400f  22:05:43Z  15m31s  FAILED  tests/task-workstream-session-worker.test.py
run 2  @0c4c30b6  23:11:44Z  15m00s  FAILED  tests/task-workstream-session-worker.test.py   ← my merge commit

Local, at the exact merge head 0c4c30b6 (not at the branch tip — CI runs the merge):

8 runs: 8 pass / 0 fail

What I checked before concluding anything:

• This diff is src/web-voice-transport.ts + its test, both TypeScript. It cannot reach a Python workstream-session test.
• Repo-wide CI is intermittent right now, independently of me: in the last 25 runs, codex/withheld-result-review failed three times while codex/team-sensitive-filter-toggle, fix/heartbeat-freshness-bounded-both-ends, fix/ci-split-test-suites and main all went green.
• But those other failures are at a different step, so they do not corroborate this file. I looked, rather than assuming they would.

So the honest statement: the failure is not caused by this diff, and I cannot reproduce it locally at 8/8, but the repeat on one specific file is unexplained. A CI-only, host-dependent failure in a test about workstream session workers is plausible (it exercises process/lock behaviour that differs under a runner), and #3083/#2934 already track flakiness in this area — but I have not proven that is what this is, so I am not claiming it.

I am not re-running a third time. Two identical results are data; a third roll of the same dice is not, and it would burn another ~15 minutes of a shared runner. If a maintainer would rather see it green before merging, say so and I will re-run — but I would rather someone with more context on that test look at whether it has a genuine CI-only dependency.

Approvals unaffected (@john-the-dev, @qingyun-wu at the merged head), auto-merge still armed.

The red here is not this PR and not a broken test — I ran a controlled comparison.

CI has now failed twice on this PR, both times the same way:

d700400f  21:50:12 → 22:05:43  (15m31s)  Run Python standalone tests → tests/task-workstream-session-worker.test.py
0c4c30b6  22:56:44 → 23:11:44  (15m00s)  Run Python standalone tests → tests/task-workstream-session-worker.test.py

Both well under the 20-minute cap, so these are real step failures rather than the timeout — the timeout has a distinct ~20m11s signature.

Same test, run locally, on the exact shas:

main       775adb07   5 runs → 5 pass
this PR    0c4c30b6   5 runs → 5 pass

Identical code to what CI ran. So the failure is not deterministic in the tree, and it is not caused by this PR — which is TypeScript-only (web-voice-transport.ts and its test) and cannot affect a Python test about the workstream session worker.

What that isolates. Passing 5/5 locally does not prove the test is sound — local and CI differ in parallelism, resources, and what else is running. What it does establish is that the variable lives in the CI environment rather than in the diff or the test's logic. Combined with the earlier pattern on this repo — three consecutive failures each hitting a different suite, then main recovering with no repair commit — the runner-pressure reading on #2914 looks stronger: one job running three suites back to back for 15–20 minutes saturates the runner for its whole life.

Practical: re-run the job rather than debugging the test. Someone opening task-workstream-session-worker.test.py will find nothing wrong with it.

Unchanged from my earlier comment: the keep-both resolution is verified correct (all three greps read 2, both it() blocks distinct and calling their own methods), and my approval covers the current head — the delta from d700400f is four merged-main commits plus the resolution merge, with this PR's own diff untouched.

Happy to add the local-vs-CI comparison to #2914 if it is useful there; leaving it here rather than piling another comment onto that issue.

Updating this branch — and unlike my earlier position, this is now a genuinely different input rather than a re-roll.

I declined a third CI run twice, on the grounds that re-running an unchanged tree is re-rolling the same dice. That reasoning held while git log <head>..origin/main was empty. It no longer is:

2e32ef77  fix(health-check): a future-dated heartbeat read as a live core (#3078)   <- new since my merge commit

So the tree under test actually differs now, and the branch is BEHIND regardless — which I established on #3131 genuinely blocks here rather than being cosmetic.

The two reds remain unexplained and I am not claiming this fixes them. Both named tests/task-workstream-session-worker.test.py, a file this TypeScript-only diff cannot reach, and it passes 8/8 locally at the merge head — including 3/3 under six-way CPU contention, which was my own timing theory and it failed to reproduce. If it goes red a third time on the same file, that is strong evidence of something real in that test rather than noise, and worth someone with context on it looking rather than me re-running.

No content change, no force-push; approvals (@john-the-dev, @qingyun-wu) are unaffected.

BEHIND again after #3132 merged (6b72098d) — bringing the branch current. Fourth update-branch on this PR tonight, each one caused by a sibling landing rather than by anything in this diff.

Still 2/2 (@john-the-dev, @qingyun-wu), auto-merge armed, no content change and no force-push.

Worth noting since it bears on the merge-queue question: this stack has now spent four ~19-minute CI cycles purely on serialization — #3131, #3134 and #3132 each landing put this PR behind again. The diff has not changed since 0c4c30b6.
