Adds the I7 cross-stack interop scenario: the Rust hang-publish reference
publisher drops its session mid-broadcast and re-announces on a fresh
transport, and the Amethyst Kotlin listener (driven through
connectReconnectingNestsListener) re-subscribes via the wrapper's
re-issuance pump.
- hang-publish gains --reconnect-after-ms <N>: at the boundary, drops
the moq_native::Reconnect handle + Origin and rebuilds a fresh
client.with_publish(...) session against the same URL. Re-creates the
broadcast under the same path so the relay sees Announce::Ended →
Active on a single suffix. frame_no (legacy timestamp) and sample_idx
(sine phase) persist across cycles for monotonic listener-side audio.
- HangInteropReverseTest.rust_hang_publish_reconnect_kotlin_listener_recovers
drives the Kotlin listener through connectReconnectingNestsListener
with the proactive JWT refresh disabled, so the only re-issuance
trigger is the publisher's cycle. Asserts ≥ 2.5 s of decoded mono
PCM with the 440 Hz spectral peak intact — pre-reconnect alone is
~1.9 s, so the threshold proves the post-reconnect re-subscribe
delivered frames.
Notes a production-side follow-up in the test threshold comment + the
results plan: with moq-relay 0.10.25 the post-reconnect chunk is
itself truncated mid-stream — the listener captures the first ~10
groups (~1.0 s) of the second cycle then stops getting new uni
streams while the publisher continues to emit them. Plausible cause
is QUIC MAX_STREAMS_UNI credit not returning fast enough on the
listener side, OR a moq-relay 0.10.x per-broadcast forward queue
holding cycle-2 frames behind cycle-1 fan-out. Out of scope for I7
(which validates the re-issuance pump fires); raise as a separate
bug if reproduced outside the harness.
