**History notes (2026-05-07):**
- Five browser-tier scenarios soft-pass on listener-side
0-frame outcomes due to the upstream moq-relay 0.10.x
routing race (`2026-05-07-late-join-catalog-flake-investigation.md`).
Hard floors lined up to land in
`2026-05-07-tighten-cross-stack-assertions.md` once the
routing race is closed.
- Suite-mode runs hit the same race intermittently;
individual-test mode is reliable. CI is intentionally not
wired (`2026-05-07-cross-stack-interop-ci-gating.md`) until
stability is achieved.
- Five browser-tier scenarios used to soft-pass listener-side
0-frame outcomes during a flake we attributed to a moq-relay
routing race; trace capture later disproved that hypothesis
and a `:quic` fix on `origin/main` closed it (see
`2026-05-07-moq-relay-routing-investigation.md` § Closure).
Hard floors landed in
`2026-05-07-tighten-cross-stack-assertions.md` after the merge:
late-join (`≥ 1.5 s after warmup`), mute-window (`≥ 2.5 s`
lower + `< 5.5 s` upper kept), I14 (`decoderOutputs ≥ 4`),
stereo (`≥ 1 s × 2 ch`), packet-loss (`≥ 0.5 s`), and the
browser-publisher helper now hard-asserts on the listener side.
Hot-swap kept a (now-documented) soft-pass on the browser
tier — Chromium's `@moq/lite` 0.2.x re-attach across
`Active::Ended → Active` is unreliable; T12 protection is
asserted by the hang-tier counterpart.

re-attaching to the new broadcast cycle. The hang-tier
counterpart hard-asserts the full post-swap window decodes
cleanly, so T12 protection is intact via the hang tier; the
browser tier currently only asserts the WT session survived
the swap (`pcm.size > warmupSamples`). Worth digging into the

## 2026-05-07 update: relay-side hypothesis disproven
The "smoking gun" trace below (speaker logs an `ANNOUNCE inbound`
but no `SUBSCRIBE inbound` for the failing broadcast) was
**correct as a description of the symptom** but **wrong about the
cause**. With the relay-side trace now captured (Step 1 of the
routing-investigation plan), we can see:
- The relay DID receive the listener's wire SUBSCRIBE
(`subscribed started` on conn{id=1}).
- The relay DID open a peer-initiated bidi to the speaker and
encode `Subscribe { id:0, track:"catalog.json" }` onto it
(`subscribe started`, `encoding self=Subscribe` on conn{id=0}).
- The speaker NEVER logs `SUBSCRIBE inbound id=0` — the bidi
doesn't reach `MoqLiteSession.handleInboundBidi`.
The same speaker connection HAS handled an earlier peer-bidi (the
relay's AnnounceInterest at T=0) correctly. So the failure isn't a
permanent dead pump; it's a per-bidi loss that affects bidi #2
some 40-60 % of the time when bidi #2 arrives ~2 s after bidi #1.
Pivot: action moved from "investigate moq-relay" to "investigate
`:quic` peer-bidi surfacing under delayed arrival" in the
routing-investigation plan, which reframes the closure-roadmap
Priority 1 actor accordingly.

unblocked; Priority 3 (`2026-05-07-cross-stack-interop-ci-gating.md`)
follows after that.
## Closure (2026-05-07, post-merge)
After the corrected diagnosis below pinned the actor on `:quic`,
five `:quic` commits had landed on `origin/main` between the
session's merge base and pickup. Merging them and re-running the
5× sweep gives:
```
sweep 1: BUILD SUCCESSFUL in 5m 9s (11/11 pass)
sweep 2: BUILD SUCCESSFUL in 2m 51s (11/11 pass)
sweep 3: BUILD SUCCESSFUL in 2m 41s (11/11 pass)
sweep 4: BUILD SUCCESSFUL in 2m 35s (11/11 pass)
sweep 5: BUILD SUCCESSFUL in 2m 34s (11/11 pass)
```
Pre-merge baseline on the same branch (commit `b2a42d9a`, same
TRACE capture, same `--rerun-tasks` shape): **3 fail / 5 sweeps**
(all `late_join_listener_still_decodes_tail`).
Post-merge sample relay trace for the previously-failing scenario
shows the speaker now responding to the upstream SUBSCRIBE in
~1.5 ms:
```
20:14:17.460567 conn{id=0} subscribe started catalog.json
20:14:17.460585 conn{id=0} encoding self=Subscribe …catalog.json
20:14:17.462141 conn{id=0} decoded result=SubscribeOk ← 1.6 ms RTT
20:14:17.462446 conn{id=0} decoded result=Group seq=0
```
vs the pre-merge failing trace where the same span had 2.94 s of
silence followed by Ended.
Likely actors among the merged `:quic` commits:
- `b622d0c9 feat(quic): RFC 9001 §6 1-RTT key update` — adds
`peekKeyPhase` + key-rotation tracking in
`QuicConnectionParser`. Pre-fix, every short-header packet whose
KEY_PHASE bit didn't match `currentReceiveKeyPhase` was silently
AEAD-failed and dropped. While quinn doesn't initiate key updates
by default, the parser path also touched the short-header
decoding side, plausibly fixing an adjacent off-by-one in
short-payload header protection (new test
`ShortPayloadHeaderProtectionTest.kt` lands alongside).
- `d5c854be fix(quic): PTO retransmits handshake CRYPTO + STREAM`
— fixes our outbound PTO when the peer never ACKs anything.
Outbound-only fix, less likely to affect the inbound bidi-data
parsing side.
- `2a4c07ae fix(quic): thread offered ALPN list through TlsClient
→ ClientHello` — affects handshake; speaker connection had
already established before the failing bidi arrived, so unlikely
to be the actor.
The empirical evidence is what counts: **5/5 sweep BUILD
SUCCESSFUL post-merge.** Bisecting WHICH of the 5 commits closes
it can be done if needed for the post-mortem; not necessary to
proceed with the closure roadmap.
## Corrected diagnosis (2026-05-07, post-trace)
5× sweep on `claude/t16-nestsclient-closure-1zBIc` (rustc 1.95,
moq-relay 0.10.25, `-DnestsHangInteropTraceRelay=true`) →
**3 failures / 5 sweeps**, all in
`late_join_listener_still_decodes_tail`. Sweeps 1, 2, 3 failed;
sweeps 4, 5 passed.
For one of the failing runs (sweep 1, broadcast suffix
`6d60532f…`), the relay's full trace + the speaker-side
`Log.d("NestTx")` lines in JUnit `<system-err>` confirm:
```
relay log (conn{id=0} = relay↔speaker, conn{id=1} = relay↔listener)
─────────────────────────────────────────────────────────────────
18:34:52.085 conn{id=0} session accepted (speaker connects)
18:34:52.085 conn{id=0} encoding AnnounceInterest (relay → speaker bidi #1)
18:34:52.092 conn{id=0} decoded Active suffix=6d60… (speaker replied to AI)
18:34:54.151 conn{id=1} session accepted (listener connects, T+2.07 s)
18:34:54.152 conn{id=1} decoded Subscribe id=0 catalog.json
18:34:54.152 conn{id=1} subscribed started …catalog.json
18:34:54.152 conn{id=0} subscribe started id=0 …catalog.json ← upstream
18:34:54.152 conn{id=0} encoding Subscribe …catalog.json ← bidi #2
18:34:57.095 conn{id=0} decoded Ended suffix=6d60… ← 2.94 s of silence
then speaker tears down
18:34:57.095 conn{id=1} subscribed cancelled id=0
18:34:57.096 conn{id=0} subscribe cancelled id=0
speaker NestTx log (matching window)
─────────────────────────────────────────────────────────────────
18:34:52.092 ANNOUNCE inbound prefix='' → emitted Active suffix='6d60…'
18:34:52.111 send returning false — no inboundSubs (count=1)
18:34:53.111 send returning false — no inboundSubs (count=51)
18:34:54.111 send returning false — no inboundSubs (count=101)
18:34:55.111 send returning false — no inboundSubs (count=151)
18:34:56.111 send returning false — no inboundSubs (count=201)
18:34:57.092 send returning false — no inboundSubs (count=250)
↑ NO `SUBSCRIBE inbound` LOG.
```
The relay opens **bidi #2** (peer-initiated bidi from relay TO
speaker) at 18:34:54.152 and writes a complete `Subscribe { id:0,
track:"catalog.json" }` message to it. The wire send succeeds (no
relay-side error). The speaker's `MoqLiteSession.handleInboundBidi`
never logs `SUBSCRIBE inbound id=0 broadcast=…6d60…` — meaning the
bidi never reaches the moq-lite session's bidi pump's
`launch { handleInboundBidi(bidi) }` body. It is silently lost
between the speaker's QUIC stack and the application layer.
The same speaker connection HAS handled bidi #1 (the relay's
AnnounceInterest at 18:34:52.085) correctly — see the
`ANNOUNCE inbound prefix=''` log at 18:34:52.092. So the speaker's
`pumpInboundBidis` is NOT permanently dead; it stops surfacing
peer-opened bidis sometime between T=0 and T+2 s, intermittently.
For comparison, sweep 4's identical scenario (which passed) shows
the relay's bidi #2 → speaker SubscribeOk round-trip in ~1.94 ms:
```
18:42:44.954530 conn{id=0} encoding Subscribe …catalog.json
18:42:44.956465 conn{id=0} decoded SubscribeOk
```
So the speaker CAN handle the late-join SUBSCRIBE bidi. It just
sometimes loses it. The 60 % flake rate matches what the prior
investigation observed.
## Why the prior investigation pointed at moq-relay
The prior plan's "smoking gun" trace observed
`ANNOUNCE inbound … emitted Active suffix='<x>'` followed by
**no** further `SUBSCRIBE inbound` for the failing broadcast on
the speaker side, and concluded the relay must have failed to
forward the SUBSCRIBE upstream. That conclusion was correct given
only the speaker-side trace; what we now have — the relay-side
trace from Step 1 capture — shows the relay DID forward, so the
gap is between the wire and the speaker's app code.
The route is therefore not `Origin::announced()`
`broadcast.subscribe_track(...)` (relay-side) but
`QUIC bidi acceptance``WtPeerStreamDemux.readyStreams`
`QuicWebTransportSession.incomingBidiStreams()`
`MoqLiteSession.pumpInboundBidis``handleInboundBidi`
(speaker-side). One link in that chain drops the second bidi about
40-60 % of the time.
## What to investigate next (out of scope here)
The next agent picking this up should look at:
1. **`:quic` module's `WtPeerStreamDemux`** — the
`readyStreams = Channel<StrippedWtStream>(Channel.UNLIMITED)`
and its `consumeAsFlow()` consumer. `consumeAsFlow` is
single-collector; we already verified only `pumpInboundBidis`
collects on the speaker side (no `pumpUniStreams` runs on a
pure publisher), so the single-consumer constraint isn't
violated, but a peer-bidi that wins the "is this the WT bidi
prefix or a control stream" classification race might be
misrouted to a different sink.
2. **WT_BIDI_STREAM prefix stripping under flow control pressure.**
`emitStripped` (`WtPeerStreamDemux.kt:292-327`) fires
`readyStreams.trySend(...)`. The path that PREBUFFERS bytes
between connection acceptance and prefix recognition is the
most likely place a long-tail bidi gets lost — there's an
`ArrayDeque<ByteArray> pending` per stream that gets flushed
into the data Flow only after the prefix is identified.
3. **Concurrent uni-stream openings during the warmup window.**
The audio publisher's `send()` returns false fast when
`inboundSubs.isEmpty()` (no uni stream opened), so the speaker
shouldn't be opening 50 fps of uni streams pre-listener. But
the audio publisher DOES eventually call
`endGroup()` on a per-group cadence (every 100 ms at
framesPerGroup=5/50fps); confirm `endGroup()` is a no-op when
there's no current group. The trace shows it firing 50 times
between T=0 and T+5 s.
This rules out **any** test-side mitigation that changes the
moq-relay version, the speaker warmup duration, or the
listener-side subscribe shape — the fault is below moq-lite, in
the QUIC stack's bidi accept path.
## Implications for the closure roadmap
- **Priority 1 of the closure roadmap is misnamed.** It's not
a moq-relay routing race; it's a `:quic` peer-bidi
surfacing race. The CI gating (Priority 3) still can't be
re-enabled until this is fixed, but the fix is in `:quic`,
not in test code or moq-rs.
- **Priority 2 (tighten cross-stack assertions) is still
blocked** by the same flake — replacing soft-passes with hard
floors makes 60 % of sweeps red, same as today.
- **Step 4 of THIS plan (bump moq-relay version) is moot.**
The bug isn't in moq-relay 0.10.x; it's in our QUIC stack's
bidi accept under a 2 s warmup. Bumping moq-relay would not
change this. (Also confirmed: 0.10.25 IS the latest crates.io
release; main HEAD `bdda6bd1` does not modify
`recv_subscribe`'s synchronous lookup either.)
## Trace artefact locations
- Per-test relay trace logs:
`nestsClient/build/relay-logs-sweep-{1..5}/<methodName>-<seq>-<ts>.log`
(kept on the branch for the next pickup; small enough to commit
if needed).
- Per-test JUnit XML with speaker `<system-err>`:
`nestsClient/build/sweep-logs/results-{1..5}/`.
- Per-sweep gradle log (build + first 50 lines of test output):
`nestsClient/build/sweep-logs/sweep-{1..5}.log`.
- Cross-reference helper:
`nestsClient/build/sweep-logs/analyze-sweep.sh` (matches by
test method name).
## Progress log (2026-05-07)
- Step 1 instrumentation landed. `NativeMoqRelayHarness` now accepts an
optional `testTag` and writes the relay subprocess's combined
stdout/stderr to
`nestsClient/build/relay-logs/<methodName>-<seq>-<ts>.log` whenever
`-DnestsHangInteropTraceRelay=true` is set. The subprocess runs with
`RUST_LOG=info,moq_relay=trace,moq_lite=trace,moq_native=debug` so
the per-broadcast subscribe-routing path is observable; quinn /
rustls / h3 stay at info to keep the file < ~10 MB per scenario.
`HangInteropTest` and `BrowserInteropTest` now expose a JUnit 4
`TestName` rule and pass the method name into `resetShared` so each
scenario's per-method log is easy to locate by name.
- Step 4 ruled out — `cargo info moq-relay` confirms `0.10.25` is the
current `crates.io` release; no newer minor exists. The plan's
Step 4 path (next minor on crates.io) does not apply. The fallback
is a `cargo install --git https://github.com/moq-dev/moq.git --rev
<main-head>` against `bdda6bd19a37ccdf7f7b66f3d760d8892ea8db59`
(main HEAD as of investigation) — moq-relay-v0.10.25 tag matches
the published crate, so post-0.10.25 work lives only on `main`.
Also note the upstream moved from `kixelated/moq` to `moq-dev/moq`;
REV's `KIXELATED_MOQ_GIT_REV` predates the move.
### Source-level analysis (moq-rs 0.10.25 + main HEAD)
Working through `moq-relay/src/connection.rs`, `moq-lite/src/lite/publisher.rs`,
`moq-relay/src/cluster.rs` and `moq-lite/src/model/{origin,broadcast}.rs`
the routing path is:
1. Speaker connects → relay's `subscriber.start_announce` runs
(`moq-lite/src/lite/subscriber.rs:198-227`). It creates the
`BroadcastDynamic` with `dynamic = 1` BEFORE calling
`cluster.publisher.publish_broadcast(...)`. publish_broadcast
pushes to the `primary` origin.
2. `cluster.run_combined()` (`moq-relay/src/cluster.rs:199-215`) is
a tokio shovel that loops on `primary.announced()` /
`secondary.announced()` and calls `combined.publish_broadcast(...)`.
This is the only place primary→combined gets fanned in, and
`tokio::select!` doesn't run in the same task as start_announce,
so there's a scheduling gap between primary publish and combined
publish.
3. Listener connects → relay's `publisher.run_announces` reads from
`combined.consume_only(...)` and forwards announces over the wire.
4. Listener subscribes → relay's `publisher.recv_subscribe`
(`moq-lite/src/lite/publisher.rs:217-250`) runs
`self.origin.consume_broadcast(&subscribe.broadcast)`
**synchronously** against combined. If the broadcast is in
combined's tree, returns Some; otherwise None → `Error::NotFound`
(wire code 13).
Even on main HEAD `bdda6bd1` the `consume_broadcast` lookup is
synchronous (`moq-lite/src/lite/publisher.rs:243-250`). Commit
`8d4a175` only renamed it to `get_broadcast` — same semantics.
Commit `bea9b3a` introduced `OriginConsumer::wait_for_broadcast`
as an async alternative AND added a TODO at
`moq-relay/src/web.rs:325`: "switch to `announced_broadcast`
(bounded by the fetch deadline) so freshly-connected subscribers
don't get a spurious 404 before the broadcast has gossiped." That
is upstream's own acknowledgement that the relay's subscribe path
inherits the gossip race, but the fix has not been applied to
`recv_subscribe` (the path this investigation cares about).
### Failure-mode hypotheses (post-source-read)
- **H1 (gossip race):** still the leading candidate, but with a
more specific mechanism. The Speaker→Relay primary publish and
the Relay→Listener combined publish are in different async
tasks; `consume_broadcast` is synchronous. The listener receives
the wire ANNOUNCE only AFTER `combined.publish_broadcast(...)`,
so by the time the listener-issued SUBSCRIBE arrives at the
relay's `recv_subscribe`, combined SHOULD contain the broadcast.
But the smoking-gun trace shows the speaker-side never logs the
upstream SUBSCRIBE for the failing path — i.e. either (a) the
listener-side ANNOUNCE→SUBSCRIBE wire ordering is being broken
by something between the relay's combined update and the wire
emit, or (b) `consume_broadcast` returns None despite combined
knowing about the broadcast. The trace from Step 1 should
disambiguate.
- **H1b (`subscribe_track` Cancel due to `dynamic == 0`):**
`BroadcastConsumer::subscribe_track` returns `Error::NotFound`
(mapped to wire code 13) if the underlying state's
`dynamic == 0` (`moq-lite/src/model/broadcast.rs:300-302`).
start_announce increments `dynamic` BEFORE publish_broadcast,
so the combined consumer's clone-of-clone-of-broadcast SHOULD
always observe `dynamic >= 1`. But it relies on `BroadcastConsumer`
/ `BroadcastProducer` sharing the same `state: conducer::Producer`
cell; if the broadcast got `Clone`d through combined's
`publish_broadcast`'s `broadcast.clone()` call into a position
where the state is shared, dynamic stays correct. (Confirmed —
`BroadcastConsumer::Clone` shares state.) So this isn't the
cause.
- **H1c (run_combined backlog):** the cluster's run_combined loop
is a SINGLE-CONSUMER pump from primary.announced(); if the loop
is parked on a slow combined publish (rare; publish_broadcast is
effectively a tree insert), a follow-up announce sits in the
primary queue. But the listener doesn't observe the announce
via combined until the pump runs — so this doesn't cause a
spurious subscribe-without-announce. It only delays the
listener's announce notification.
The trace from Step 1 is needed to pick between H1, H1c, and a
bug we haven't surfaced yet. **Step 4 will not yield a fix**
verified by reading post-0.10.25 commits on main; no fix to
`recv_subscribe`'s synchronous lookup has landed. The most
viable upstream fix would be to switch `recv_subscribe` to
`origin.wait_for_broadcast(path).await` with a bounded deadline.

mask flake rather than catch regressions.

**What lands.**
- Either an upstream moq-relay version bump that closes the bug,
OR a documented relay configuration tweak that does.
- Or, if neither: a filed `kixelated/moq` issue with reproducer +
trace pair, plus a documented decision to keep CI unwired until
upstream resolves.
**What landed.**
- A 5-commit merge from `origin/main` carrying ALPN-list
threading, PTO STREAM retransmits, RFC 9001 §6 1-RTT key
update, multiconnect/multiplex pacing, and qlog flush.
- Per-test moq-relay TRACE capture instrumentation
(commit `d7f87971`) — kept in place; useful for follow-up
regression triage.
- Cross-stack trace artefacts preserved at
`nestsClient/plans/artefacts/2026-05-07-routing-race-disproven/`

- Five BrowserInteropTest scenarios get hard sample-count + FFT
floors (or tightened existing ones).
- Gap matrix updated to reflect hard-pass coverage.
**What landed.**
- 7 BrowserInteropTest scenarios + the
`runBrowserPublishKotlinListen` helper get hard sample-count
floors (no `return@runBlocking` short-circuits remain).
- One scenario (`chromium_listener_speaker_hot_swap_does_not_crash`)
hard-asserts a weaker bound than originally specced — the
Chromium `@moq/lite` 0.2.x client only captures ~100160 ms
across the swap; the hang-tier counterpart still hard-asserts
the full post-swap 440 Hz peak so T12 protection is intact.
Deferred follow-up tracked in
`2026-05-06-cross-stack-interop-test-results.md`.

on false reds).
**What lands.**
- Re-add `hang-interop` job (was at commit `6829ab727`'s parent;
`git show 6829ab727 -- .github/workflows/build.yml` reverse
gives the exact diff).
- Re-add `browser-interop` job (same pattern, plus bun +
Playwright caches).
- Documentation update across the results plan + gap matrix.
**Acceptance bar.** 10/10 sweep before merge; ≥ 95% CI green
rate over the first 2 weeks. If lower, the upstream race isn't
fully closed — pull the jobs.

# Trace artefacts: `late_join_listener_still_decodes_tail` flake (2026-05-07)
These three files are the evidence that disproves the
"moq-relay 0.10.x per-broadcast subscribe-routing race" hypothesis
in `nestsClient/plans/2026-05-07-moq-relay-routing-investigation.md`.
Captured by Step 1 of that plan: per-test moq-relay trace logging
(`-DnestsHangInteropTraceRelay=true`) over a 5× sweep of
`HangInteropTest`. Failure rate observed: 3/5 sweeps, all in
`late_join_listener_still_decodes_tail`. Sweeps 1, 2, 3 failed;
4, 5 passed.
## Files
- `sweep-1-FAIL-relay-trace.trace.txt` — moq-relay subprocess stderr
with `RUST_LOG=info,moq_relay=trace,moq_lite=trace,moq_native=debug`
for the failing scenario in sweep 1 (broadcast suffix
`6d60532f…`). 39 lines; ANSI stripped.
- `sweep-1-FAIL-speaker-NestTx.trace.txt``Log.d("NestTx")` lines from
the JUnit XML `<system-err>` filtered to the failing test's time
window (`18:34:52``18:34:57`).
- `sweep-4-PASS-relay-trace.trace.txt` — same scenario, sweep 4, where
the speaker DID respond to the relay's upstream SUBSCRIBE. Use
this for the diff.
## How to read them
The crucial claim is: in the FAIL trace, the relay opens a
peer-initiated bidi to the speaker at 18:34:54.152 and writes
a complete `Subscribe { id:0, track:"catalog.json" }` message
to it (lines containing `subscribe started` and
`encoding self=Subscribe`). The speaker's NestTx log has NO
matching `SUBSCRIBE inbound id=0`. Therefore the wire SUBSCRIBE
message is lost between QUIC's bidi accept path and
`MoqLiteSession.handleInboundBidi`.
The PASS trace shows the same scenario completing the
relay→speaker SubscribeOk round-trip in ~1.94 ms, confirming the
speaker-side handler IS capable of processing this bidi when it
manages to reach the application.
## What this rules out
- moq-relay 0.10.x's `Origin::announced()``consume_broadcast`
race. The relay's lookup succeeds and the upstream subscribe
IS opened.
- Speaker-side hook installation race. The speaker logs
`ANNOUNCE inbound prefix=''` correctly at T=0 but the LATER
bidi never reaches handleInboundBidi at all.
- Test framework / test ordering. Same failure recurs across
per-method `resetShared()` boots and survives sweep 5's
successful run vs sweep 1's failure on the same harness.
## What it points to
The QUIC stack's path from peer-initiated bidi acceptance →
`WtPeerStreamDemux.readyStreams.trySend(...)`
`incomingStrippedStreams.consumeAsFlow()`
`MoqLiteSession.pumpInboundBidis`. One of those handoffs drops the
bidi 40-60 % of the time when bidi #2 arrives ~2 s after bidi #1
on the same connection.

# Cross-stack interop tests
> Manually invoked. Not part of `build.yml` — see "Why not in CI" below.
Two suites that drive the production Amethyst Kotlin nests stack against
external reference implementations of moq-lite-03:
| Suite | Path | Runs | What it asserts |
|---|---|---|---|
| **`HangInteropTest`** | `nestsClient/tests/hang-interop/` | Rust `hang-listen` / `hang-publish` (kixelated reference) ↔ Amethyst Kotlin via a real `moq-relay` 0.10.x subprocess | Wire-byte capture, FFT peaks on decoded PCM, sample-count floors, mute / hot-swap / packet-loss / late-join / 60 s long broadcast / multi-listener fan-out. |
| **`BrowserInteropTest`** | `nestsClient/tests/browser-interop/` | Headless Chromium running `@moq/lite` + `@moq/hang` via Playwright ↔ Amethyst Kotlin (forward + reverse) | Same scenario family as hang-interop, plus WebCodecs `AudioDecoder` / `AudioEncoder` correctness, ALPN negotiation, browser-side reconnect. |
Coverage matrix: [`nestsClient/plans/2026-05-06-cross-stack-interop-test-gap-matrix.md`][gap]
[gap]: ../plans/2026-05-06-cross-stack-interop-test-gap-matrix.md
## When to run
Run **both suites locally before merging** any change that touches:
- `quartz/.../nip53` (audio rooms event types, catalog wire format)
- `nestsClient/src/.../moq/lite/` (moq-lite session, publisher/subscriber, codec)
- `nestsClient/src/.../audio/` (capture, encoder/decoder, broadcaster, player)
- `nestsClient/src/.../MoqLiteNestsSpeaker.kt` / `MoqLiteNestsListener.kt`
- `nestsClient/src/.../ReconnectingNests*.kt`
- `:quic` (WebTransport, packet header protection, key updates, stream demux)
- The hang/browser sidecars themselves
Skip if the change is documentation, UI-only, build-script-only, or otherwise
can't affect wire bytes / decoded audio.
## Quick start
```bash
# Hang-tier (Rust ↔ Kotlin via real moq-relay subprocess)
./gradlew :nestsClient:jvmTest \
--tests "com.vitorpamplona.nestsclient.interop.native.HangInteropTest" \
-DnestsHangInterop=true
# Browser-tier (Chromium ↔ Kotlin) — also boots the moq-relay
./gradlew :nestsClient:jvmTest \
--tests "com.vitorpamplona.nestsclient.interop.native.BrowserInteropTest" \
-DnestsHangInterop=true \
-DnestsBrowserInterop=true
# Both together
./gradlew :nestsClient:jvmTest \
--tests "com.vitorpamplona.nestsclient.interop.native.HangInteropTest" \
--tests "com.vitorpamplona.nestsclient.interop.native.BrowserInteropTest" \
-DnestsHangInterop=true -DnestsBrowserInterop=true
```
The opt-in flags (`-DnestsHangInterop=true` / `-DnestsBrowserInterop=true`)
also act as JUnit `Assume` gates — without them, the suites mark every
scenario `skipped` rather than failing on missing prerequisites.
## Prerequisites
| Tool | Why | Install |
|---|---|---|
| **Rust ≥ 1.95** | `moq-relay` 0.10.25's transitive dep `constant_time_eq 0.4.3` requires it | `rustup install 1.95 && rustup default 1.95` |
| **`cargo`** on PATH | Builds the hang-interop sidecars + `cargo install`s `moq-relay`, `moq-token-cli` | Comes with rustup |
| **`bun` ≥ 1.3.x** (browser only) | Bundles the Chromium harness + drives Playwright | `curl -fsSL https://bun.sh/install \| bash` |
| **Playwright Chromium** (browser only) | Headless Chromium for `@moq/lite` + `@moq/hang` | Auto-installed by `interopInstallPlaywrightChromium` Gradle task |
The Gradle build automates everything from there. First run installs and
caches:
- `moq-relay` 0.10.25 + `moq-token-cli` 0.5.23 → `~/.cache/amethyst-nests-interop/hang-interop-cargo/bin/`
- Sidecar release binaries → `nestsClient/tests/hang-interop/target/release/`
- bun's `node_modules` + `dist/``nestsClient/tests/browser-interop/`
- Playwright Chromium → `~/.cache/ms-playwright/`
Cold first run: ~10 min hang, ~13 min browser. Cached: ~3-4 min hang,
~5-7 min browser.
## Configuration knobs
| Flag | Default | Purpose |
|---|---|---|
| `-DnestsHangInterop=true` | unset (skip) | Enable HangInteropTest. |
| `-DnestsBrowserInterop=true` | unset (skip) | Enable BrowserInteropTest. Implies `nestsHangInterop` (the browser harness boots the same `moq-relay` subprocess). |
| `-DnestsHangInteropTraceRelay=true` | unset | Per-test moq-relay trace capture. Writes the relay subprocess's combined stdout/stderr (with `RUST_LOG=info,moq_relay=trace,moq_lite=trace,moq_native=debug`) to `nestsClient/build/relay-logs/<methodName>-<seq>-<ts>.log`. Use for debugging suite flakes. |
| `-DnestsHangInteropDiagnostic=true` | unset | Runs the Kotlin↔Kotlin variant gated separately (`KotlinSpeakerKotlinListenerThroughNativeRelayTest`) — useful to bisect wire-format bugs without involving Rust or Chromium. |
| `BUN_BIN`, `NPX_BIN` (env) | autodetected | Override the bun / npx binary path if your install lives outside the agent default (`/root/.bun/bin/bun`). |
## Known limitations
- **`chromium_listener_speaker_hot_swap_does_not_crash`** soft-passes its
PCM assertion — Chromium's `@moq/lite` 0.2.x doesn't re-attach across
`Active::Ended → Active`, so the browser captures only ~100 ms post-swap.
T12 (group sequence carry across hot-swaps) is hard-asserted by the
hang-tier counterpart.
- **`framesPerGroup`** is pinned to `5` in the test scenarios. Production
defaults to `50`. The two haven't been reconciled against a single
multi-rig benchmark — see
[`framespergroup-reconciliation`](../plans/2026-05-07-framespergroup-reconciliation.md).
- **I7 cycle 2 truncation**: `moq-relay` 0.10.x truncates the second
cycle of a publisher reconnect at ~1.0 s out of ~2.5 s. Tests assert
`≥ 2.5 s` floor which the truncated cycle still clears; a future
upstream fix may let us tighten further.
- **I12 GOAWAY**: not applicable to moq-lite-03; only the IETF
moq-transport target (currently disabled) would exercise it.

## Debugging a flaking scenario
1. Re-run the failing scenario in isolation (no `--tests` filter races):
```bash
./gradlew :nestsClient:jvmTest \
--tests "*HangInteropTest.late_join_listener_still_decodes_tail" \
-DnestsHangInterop=true \
-DnestsHangInteropTraceRelay=true \
--rerun-tasks
```
2. Inspect `nestsClient/build/relay-logs/<methodName>-*.log` for
`subscribed started` / `encoding self=Subscribe` /
`decoded result=SubscribeOk` / `subscribed cancelled` events.
3. Cross-reference with the speaker-side `Log.d("NestTx")` lines
captured in JUnit XML's `<system-err>`
(`nestsClient/build/test-results/jvmTest/TEST-*.xml`) by timestamp.
4. The fastest diagnostic loop bypasses Browser/Chromium entirely — use
the diagnostic test:
```bash
./gradlew :nestsClient:jvmTest \
--tests "*KotlinSpeakerKotlinListenerThroughNativeRelayTest" \
-DnestsHangInteropDiagnostic=true
```
Sample pre/post-merge trace pair for the previously-flaking late-join
scenario lives at
[`plans/artefacts/2026-05-07-routing-race-disproven/`](../plans/artefacts/2026-05-07-routing-race-disproven/)
+ [`plans/artefacts/2026-05-07-routing-race-closed-by-merge/`](../plans/artefacts/2026-05-07-routing-race-closed-by-merge/).
## Why not in CI
Both suites are slow on a cold cache (~1013 min each), and even on a
warm cache the browser tier dominates the critical path at ~5-7 min.
Running them on every PR doubles CI time for changes that don't touch
audio / MoQ / QUIC.
History:
- `21947bc5` re-added both jobs after the T16 closure roadmap closed
Priority 1 (`:quic` post-handshake bidi-drop fixed via `origin/main`
merge) and Priority 2 (assertion hardening). 10/10 sweep × 22 tests
= 220/220 hard-pass on the merged branch.
- A subsequent maintainer review judged the wallclock cost too high
for the change-pattern (most PRs don't touch the relevant code) and
removed the jobs.
The suites still run locally per the rules above. If a PR DOES touch
audio / MoQ / QUIC code paths and the author hasn't run them, ask in
review.
## Files
- `hang-interop/REV` — pinned upstream versions (`MOQ_RELAY_VERSION`,
`MOQ_TOKEN_CLI_VERSION`, `HANG_VERSION`, `MOQ_LITE_VERSION`,
`MOQ_NATIVE_VERSION`). Bump deliberately.
- `hang-interop/Cargo.toml` + `hang-{listen,publish}/`,
`udp-loss-shim/` — Rust sidecar workspace.
- `browser-interop/package.json` + `src/` + `playwright.config.ts`
bun + Playwright harness.
- `nestsClient/src/jvmTest/kotlin/.../interop/native/`:
