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 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=''` 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(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 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}/--.log` + (kept on the branch for the next pickup; small enough to commit + if needed). +- Per-test JUnit XML with speaker ``: + `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/--.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 + ` 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. **Owns:** the residual flake that affects four T16 scenarios: `late_join_listener_still_decodes_tail`, diff --git a/nestsClient/plans/2026-05-07-t16-closure-roadmap.md b/nestsClient/plans/2026-05-07-t16-closure-roadmap.md index d962e0c3f..f5fd82852 100644 --- a/nestsClient/plans/2026-05-07-t16-closure-roadmap.md +++ b/nestsClient/plans/2026-05-07-t16-closure-roadmap.md @@ -15,56 +15,75 @@ This roadmap takes the suite from "passes individually" to "passes in suite + CI" through three sequential plans.

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 `` 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. diff --git
