feat(net): connect policy lives in moq-net as a poll machine - #7904
Client connect policy now lives in moq-net as moq_net::Reconnect, a poll machine that does no I/O:
The connect deadline over dial plus handshake, and the per-address bound (5 s for an address with a fallback).
The address walk: which verdicts settle it, and which failure the walk reports.
Backoff with jitter, the healthy-session reset, and the give-up window.
GOAWAY handling: the redirect policy (Follow, SameHost, Ignore, certificate pins, fixed addresses), Brent loop detection, Restart::{Redial, Wait}, and the drained predecessor's handover, idle close, and retirement.
Token presentation and refresh: a refused credential retries only after the tokens change, and an ended auth handle ends the policy.
The caller dials each Attempt it asks for and reports connected or failed with a Verdict. The machine watches the live session's close and GOAWAY itself and returns Actions (Dial, Abandon, Migrating, Retired, Offline, Retrying, Wait, Done). moq-tokio's Connection loop now drives it. moq-tokio keeps the dialing (DNS, Happy Eyeballs, sockets, TLS, the QUIC/WebSocket race), its CLI config, the Monitor state it publishes, bandwidth forwarding, and spawning.
moq-dev/moq#7607 landed first (maintainer's pick, 2026-11-05) and turned the handshake behind moq_net::Client::connect(now, transport) into the private Connect poll machine. The two layer rather than overlap: Reconnect decides which address to dial and bounds each dial, and the caller's dial runs the transport and then Client::connect, whose Connect machine is the only handshake. An Action::Abandon at the deadline drops the dial, handshake included. Reconnect sits behind moq-net's async feature, like Session and Client, since it watches sessions.
Public API and wire impact
moq-net (additive, async feature): new reconnect module (Reconnect, Config, Backoff, Goaway, Redirect, Restart, Target, Verdict, Failure, Attempt, Action, ConfigError), with Reconnect re-exported at the root. moq_net::Client is unchanged beyond what feat!: generate async wrappers behind default-off async features #7607 already broke.
moq-tokio (unchanged shape): Restart is now a re-export of moq_net::reconnect::Restart with the same variants. Backoff, Goaway, Redirect, Connection, Monitor, and the Error variants a connection reports (ConnectTimeout, Reconnect, RefusedRedirect, PinnedRedirect) keep their shape and messages.
moq-ffi: test-only change.
Wire: none. Defaults and CLI flags are unchanged.
So this is not marked ! and adds no MIGRATE notes; see the first choice below.
Choices made without asking
No break to moq_net::Client, re-checked after feat!: generate async wrappers behind default-off async features #7607. The quest expected one, and feat!: generate async wrappers behind default-off async features #7607 has since broken Client::connect anyway, so the question was whether the connect deadline or the policy should now move into Client/Connect. It should not: the deadline must cover the transport dial too, which Client::connect never sees, so a deadline there would still need the caller to bound the dial separately. The alternative, Reconnect owning the handshake (the caller hands it each transport and it runs Connect, then hands back the driver to spawn), adds a handshake phase and a driver-handoff action to Reconnect, while connect_webrtc and moq-tokio's QUIC/WebSocket race would still call Client::connect directly. Keeping the handshake in Client::connect is the smaller API with one handshake path.
Generic over the caller's address and error types (Reconnect<A: Target, E>). Target (URL, plus whether it dials fixed socket addresses) lets moq-tokio keep connect::Addr without a parallel list. E: From<moq_net::Error> + From<Failure> keeps moq-tokio's Error as what Connection::closed reports.
The caller judges its own dial errors through Verdict (Retry, Unusable, Settled, Refused, Fatal). moq-net judges MoQ errors with impl From<&moq_net::Error> for Verdict, which moq-tokio's is_terminal now reuses instead of keeping its own list.
moq-tokio's Redirect stays a separate CLI enum that converts to moq-net's. Its usage_rs::ValueEnum derive can't be added to a moq-net type, and moq-net shouldn't depend on usage-rs.
connect_webrtc still bounds its own channel setup with policy.timeout. A pre-established peer has no address to walk; moq-tokio becomes a thin shell owns routing it through moq-net.
No JS change. This only moves Rust code; js/net's connection behavior is untouched.
moq-dev/moq#7848 (fresh UDP port after two failed walks) is ported onto the driver: it stays in moq-tokio, since replacing a socket is tokio's job. The driver counts a Retrying that follows a failed or abandoned dial as a failed walk, resets the count on connect, and replaces the port at the second failure, before the backoff instead of before the next walk, which has the same effect. Each dial owns a clone of the Client, so the port can change while no dial is in flight. Its "explicit shutdown" exit became a Verdict::Fatal for a failed QUIC dial on a closed client. The four fresh_port integration tests pass unchanged.
The drill mutation reconnect-stops-after-session-loss is retargeted at moq_net::Reconnect's close handling. just test drill-sensitivity reconnect-stops-after-session-loss shows relay_killed_mid_group_aborts_then_resumes::loopback passing at baseline and failing under the mutation.
Merge queue failure
The queue later dropped fc3a87f531 for a conflict with main, resolved in 20a8110021: sh/gh/test-inventory.allow keeps both datagram entries (datagrams_cross_a_default_connection from main, requested_datagrams_cross_a_default_connection from this PR); quest/m1/session-policy/connect.md stays deleted (main had only moved one of its links to m5); quest check --fix dropped its link from quest/m2/recut-held.md. Apart from those quest-file lines, git diff origin/main...HEAD matches the previous head's diff.
Cause: the test ran on a paused tokio runtime and stamped each group's arrival on that runtime's clock, but moq-ffi's Polled::poll enters the FFI root runtime, whose kio clock is the shared real one. A paused runtime counts from its own first reading, so the reader's "the newest group landed a whole reach ago" fallback compared two timelines and fired once the process had run 500 ms of real time (the CI run took 0.77 s). A 600 ms std::thread::sleep before the writes reproduces it every time.
Fix: the test writes all three groups, newest first, before the first read, so the start decision reads no clock. It still proves the warmup reaches the start: dropping the warmup from moq-mux's start skip fails it with [4700000, 5000000]. moq-mux's start-reach tests (the_start_waits_for_an_earlier_group_when_the_live_edge_arrives_first and siblings) keep covering the timed wait on a single clock. It passes with the 600 ms stall and in a 100-run stress loop.
Requested datagram quarantine
This PR keeps #[ignore] on moq-ffi::test::requested_datagrams_cross_a_default_connection (pullfrog's 14eb297612), plus its sh/gh/test-inventory.allow entry. CodeRabbit asked for both to be removed, since ffi-datagram-roundtrip.md quarantines only the plain sibling. It stays because of this evidence:
Check on 5ff394e75c failed it: FAIL [10.157s], a panic at rs/moq-ffi/src/test.rs:6111 after the single appended datagram missed the 10 s wait. This is the same symptom as the plain sibling's failure on moq-dev/moq#7914.
On 20a8110, quest gate nix develop --command just rs test -p moq-ffi --lib -E 'test(requested_datagrams_cross_a_default_connection)' --run-ignored all --stress-count 100 passed 100/100 on an idle host. That points to a failure under load, not one this PR's code causes on every run.
Removing the ignore would bring back a CI failure that has already been observed. The quest's prose ("its requested siblings ... remain enabled") is out of date for this case. Its Goal already names the requested_ sibling, and its Waiting step reproduces it under load. The maintainer still needs to decide who owns the plan; see the report.
Tests
The policy's timing tests moved to moq-net and run on kio's simulator with in-memory sessions, asserting exact instants: an immediate-close loop escalates until the timeout, a restart loop escalates without giving up, a redirect loop escalates until the timeout, and a zero initial redials at once.
New moq-net coverage: the walk lands past dead addresses; only an address with a fallback is bounded; a settled answer stops the walk; an unusable address ends only a walk with nothing else; a refusal retries only new tokens; an ended auth handle ends the policy; connecting once; fixed targets refuse redirects; refused redirects are terminal; a healthy GOAWAY hands over and the idle predecessor closes; the handover caps the peer's deadline and retirement between sessions goes offline; a connect cancels the offline a mid-dial retirement queued; Restart::Wait; and credentials stay out of logs and errors.
The pure redirect, pacing, loop-detection, and endpoint tests moved with their code.
moq-tokio keeps its socket-level and Monitor tests. The dial_any tests now drive a one-shot Connection.
Validation
On 20a8110 (after merging main at 0672ad5): quest gate nix develop --command just check origin/main passed every module (rs check and test, py, c, cpp, obs, biome, js, kt, swift, go, drill, quest, shell, large_files, text, toml, nix, justfile, markdown, check gh). The exception was test gh, which never finished. It was stuck on /tmp/moq-bench.lock, the shared benchmark lock that another session's bench/browser/run.sh held at the time. That's a host contention issue, not this PR. Every other line of .github/justfile's test recipe ran separately and passed (43 commands). Only bash sh/local.sh python3 bench/build.test.py was skipped, because it waits on that lock. CI runs the full suite.
quest gate nix develop --command just check origin/main passed on 5ff394e75c, after merging main with feat!: generate async wrappers behind default-off async features #7607: 10,885 Rust tests passed with 135 skipped, plus the py, C, C++, OBS, JS, markdown, gh, Kotlin, Swift, Go, drill, quest, shell, toml, nix, justfile, and Dart checks.
cargo nextest run -p moq-net --all-features reconnect: the new a_connect_cancels_the_offline_a_retirement_queued failed before the fix ("a stale offline followed the connect") and passes after; 41 passed.
moq-ffi warmup test: fails with a 600 ms stall before the writes on the old test, passes with it on the new one, passes 100/100 under --stress-count, and fails under a mutation dropping the warmup from moq-mux's start skip.
Earlier, on 8fff1a7304: just test drill-sensitivity reconnect-stops-after-session-loss caught the retargeted mutation.

Codex, gpt-6.1-sol, medium effort (quest review --base origin/main), session 01a1afa3-0c4a-7043-9e71-c1abd49b27b5, round 1 on 20a8110021 (the merge of main that resolves the queue conflict): no findings. CodeRabbit's open is_local thread on rs/moq-net/src/reconnect/redirect.rs:119 is resolved, still declined: the moved is_local has the same logic as main's rs/moq-tokio/src/connection.rs:387, and only a comment differs.

Round 2, on 5c99f90d2c (merge of origin/main plus pullfrog's 14eb297612, kept: it ignores requested_datagrams_cross_a_default_connection, which timed out in this PR's Check; #7954 ignores only the plain sibling, and quest/m0/test-flakes-2/ffi-datagram-roundtrip.md already covers both): no findings. just check origin/main passed.
Earlier session, before the merge: round 1 on 8fff1a7304 found the aborted task leaving the mirrored predecessor in State (fixed in Shared::end); round 2 on d4c8dcf2fb found nothing.
Online reviews on d4c8dcf (pullfrog and the OpenAI review): a stale queued Offline after a connect. Fixed in 1c259a9ded: connected() drops queued Offlines and keeps Retired, with a test that connects between the two.
Suggested follow-ups
Numeric IPv4 hosts (such as 2130706433) under Redirect::Follow: is_local treats them as remote, though glibc resolves them to loopback. This is pre-existing and was raised by CodeRabbit on the moved code; worth a hardening quest.
moq_net::Reconnect owns the connect deadline, the address walk, backoff,
GOAWAY handling and token refresh, doing no I/O. moq-tokio's Connection
dials what it asks for and publishes what it does.

Walkthrough
moq-net adds an async-feature reconnect policy that manages address walks, retries, authentication changes, GOAWAY redirects, and session handovers. moq-tokio now drives that policy, supplies dial attempts, and publishes its connection state. The change adds redirect validation and cycle tracking, updates session close helpers and error mapping, and revises policy and connection tests. FFI test timing checks and the CI inventory entry for a flaky datagram test also change.
Merge Risk: Low · up to 897e4
The reconnect policy move preserves existing behavior. Two minor edge cases remain open: an exhausted policy may still announce recoverable states, and redirects to numeric IPv4 hosts are not treated as local. Owners should be aware, but neither blocks merging.

ℹ️ No critical issues — one queue-coherence suggestion below.
Reviewed changes
The policy moved into moq_net::Reconnect: the connect deadline (dial plus handshake, with the 5 s bound only when a fallback exists), the address walk and verdict handling, backoff/jitter and the give-up window, GOAWAY redirect/restart/handover, and token presentation/refresh now live in a no-I/O poll machine (rs/moq-net/src/reconnect.rs, reconnect/redirect.rs).
moq-tokio drives it: Connection::run became a dial-and-publish loop; Client holds a reconnect::Config; Error::is_terminal reuses Verdict; Restart is a re-export. Session::{poll_closed, start_close} were split out for polling.
Tests relocated: the timing, redirect, pacing, and loop-detection tests moved to moq-net on kio's simulator; moq-tokio keeps socket-level, Monitor, and reconnect-loop coverage, and the dial_any cases now drive a one-shot Connection.
Docs and quests: the new machine is documented in doc/lib/rs/moq-net.md; the completed connect.md quest is removed and the follow-up quests updated; the drill mutation is retargeted at reconnect.rs.
I checked the moved policy against the pre-refactor moq-tokio behavior (deadline selection, walk verdict/transient precedence, healthy reset vs redirect-loop reset, once exits, refusal-only-on-changed-tokens, predecessor handover, fresh-port accounting, and the Failure -> Error messages) and found no behavioral regression there. The round-1 Shared::end fix also holds up: Connection::close takes its clone under CloseGuard before aborting, and abort/drop/panic drops the policy's own clone.
ℹ️ A connect can be followed by a stale Offline
poll drains queue before the phase, and connected() leaves the queue untouched. So a driver that handles the Retired action left by a predecessor retiring mid-dial, then reports that in-flight dial's success, receives Offline(None) next and publishes the live session as disconnected. moq-tokio's run is safe today only because its ready actions are drained in a tight synchronous loop; the machine is public for drivers (the io_uring quest) that poll the dial and the machine separately.
Technical details
# A connect must cancel a queued offline## Affected sites-`rs/moq-net/src/reconnect.rs:455-461` — queues `Retired` then `Offline(None)` when the predecessor retires while `!live`.
-`rs/moq-net/src/reconnect.rs:442-446` — `poll` returns queued actions before the phase, so the queued `Offline` outlives a later `connected()`.
-`rs/moq-net/src/reconnect.rs:524-542` — `connected()` moves to `Live` without touching `queue`.
-`rs/moq-tokio/src/connection.rs:1033-1036` — `Offline` clears `forward` and calls `Shared::offline`, dropping the session from published state.
## Scenario
A GOAWAY migration starts a replacement dial. The predecessor's handover deadline expires while that dial is in flight (`Phase::Dialing`, so `live == false`), queueing `[Retired, Offline(None)]`. The caller pops `Retired`, then the dial resolves `Ok` and the caller reports `connected()` before polling again. The next `poll` returns `Offline(None)`, and the driver clears the just-connected session: `Status::Disconnected`, `stats`/`version``None`, `forward` dropped, and `established()`/`Monitor` offline until that session ends.
This is reachable through the documented API, since a caller may poll its dial and the machine separately (e.g. `select!`); the io_uring dial quest is the next intended driver. `moq-tokio`'s `run` does not hit it today only because its ready actions are drained in a tight synchronous loop, so the dial future cannot become ready between `Retired` and `Offline`.
## Required outcome
A connect must never be followed by an `Offline` that predates it.
## Suggested approach
In `connected()`, drop queued `Offline` actions: `self.queue.retain(|a| !matches!(a, Action::Offline(_)))`. `Retired` must still be delivered so the driver clears the mirrored predecessor, and `Offline(Some(_))` cannot coexist with a connect.
[P2] Cancel an obsolete queued Offline when a dial connects — rs/moq-net/src/reconnect.rs:455–461, 524–541. I independently confirm the queue-coherence issue raised in the latest review: retiring a predecessor mid-dial queues Retired then Offline(None), but connected() enters Live without removing that Offline. This can affect the current tokio driver too: it polls the dial before each policy poll (connection.rs:959–995), so a handshake completed by another runtime thread between those two actions publishes Connected and then consumes the stale Offline, clearing the new session from Monitor/established() and stopping bandwidth forwarding until another reconnect. No explicit yield between actions is needed for another thread to complete the dial. Invalidate the obsolete offline action on connection, retaining Retired, and test success arriving between Retired and Offline.
Direction: moving the policy into one no-I/O machine is sound and avoids another runtime-specific copy. The predecessor cleanup fix in Shared::end is present; the remaining event-coherence issue should be fixed before landing.
Verification: GitHub-only static comparison with the previous tokio policy, inspection of the new machine/redirect logic, driver, close/auth paths and tests. No tests, transport drills or feature-matrix builds executed.

Important
The new commit is correct, but the queue-coherence bug raised in the previous review is still present at d4c8dcf2f, so this is not ready to land.
Reviewed changes
Cleared the mirrored predecessor when the loop ends: Shared::end now drops state.predecessor, so aborting the task mid-handover can no longer leave a session clone parked in State that holds the transport open. The graceful path is unaffected because Connection::close clones the predecessor under CloseGuard before aborting.
Merged main: the branch was updated onto 322c434a9; the merge changes no policy behavior.
The rest of the PR (the moq_net::Reconnect machine, the moq-tokio driver, and the relocated tests) was covered by the previous review.
⚠️ The queued Offline that follows a connect remains
connected() still enters Live without clearing the queue, so a Retired/Offline(None) pair queued while the replacement was dialing can survive the connect and clear the freshly connected session from State. Neither the new commit nor its predecessor touches this path, and both earlier reviews flagged it; it remains a blocker rather than a new finding.
Technical details
# Cancel the obsolete queued Offline when a dial connects## Affected sites-`rs/moq-net/src/reconnect.rs:454-461` — a predecessor retiring while `!live` queues `Retired`, then `Offline(None)`.

The build stopped because `pkg-config` couldn’t find PipeWire. Its development files are already installed locally, so I’m retrying with their search paths set. No repository changes are needed for that retry.

quest land check: truncated check protocol
A predecessor retiring while its replacement dials queues Retired then
Offline(None). A driver that reports the dial's success between the two
then consumed a stale Offline and published the live session as gone.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The reader polls inside the FFI runtime, whose clock is the shared real
one, while the paused test runtime stamped the groups on its own timeline.
Once the process had run 500 ms of real time, the start's reach fallback
fired and the reader started without waiting, failing the merge queue
under load. Write every group before the first read instead, so the start
decision reads no clock; moq-mux's start-reach tests cover the timed wait.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Fixed the stale queued Offline both reviews raised on d4c8dcf, in 1c259a9ded: Reconnect::connected now drops queued Offline actions and keeps Retired, so the driver still clears the mirrored predecessor. a_connect_cancels_the_offline_a_retirement_queued connects between Retired and the next poll; it failed before the fix and passes after.
The reason will be displayed to describe this comment to others. Learn more.
✅ No new issues found. The queued-Offline blocker from the last review is fixed and covered by a regression test.
Reviewed changes
Cancelled the queued Offline on connect: Reconnect::connected now drops any queued Action::Offline while keeping Retired, so a predecessor retiring mid-dial can no longer unpublish the session that connects next. The new test drives a dial that outlives the handover, connects between Retired and Offline, and asserts Wait(None).
Removed the clock from the FFI warmup test: it writes all three groups newest-first before the first read, so the start decision no longer compares a paused runtime's clock against the FFI runtime's, which is what flaked the merge queue. Test-only, and the timed start wait stays covered by moq-mux's start-reach tests.
Merged main: the branch picked up d0c73e3; within this PR's files that is main's kio::wrapper/poll_ended churn in connection.rs and session.rs, with no policy change (reconnect.rs and reconnect/ are untouched by the merge). The retargeted drill mutation still applies cleanly against the current file.
I re-checked the retain against the machine's phases: while Phase::Dialing, the queue can only hold the Retired/Offline(None) pair pushed when a predecessor retires with nothing live (Offline(Some) is only queued by closed(), which leaves Live for Backoff or Done), and poll drains the queue before returning a Dial, so nothing a caller has not already seen is dropped.
The failing check was moq-ffi test::requested_datagrams_cross_a_default_connection: it appends one datagram after consumer.info() and waits 10 s, and the datagram never arrived under CI load. The test lives on main (it predates this PR) and passed in the last green Check on this branch; it also passes 30 of 30 focused runs here, and the sibling datagram connection tests are already tracked as flaky under CI load in quest/m0/test-flakes-2/ffi-datagram-roundtrip.md. This is the known one-datagram timeout, not the connect-policy code.
Per the repo's flaky-test rule, I quarantined it and registered it with the existing follow-up quest:
rs/moq-ffi/src/test.rs: #[ignore = "flaky under CI load; tracked in quest/m0/test-flakes-2/ffi-datagram-roundtrip.md"] on test::requested_datagrams_cross_a_default_connection.
Verified python3 sh/gh/test-inventory.py exits 0 with the new entry, cargo fmt --all -- --check is clean, and the ignored test still passes when run explicitly. Pushed as 14eb29761 to quest/m1/session-policy/connect (the push was briefly blocked while the PR sat in the merge queue; it went through once the queue ejected it).
Check failed on test::requested_datagrams_cross_a_default_connection: the single datagram it appends after consumer.info() never arrived within the 10 s wait. It passes 30 of 30 focused runs on an idle host, and the plain datagram connection test is already quarantined in quest/m0/test-flakes-2/ffi-datagram-roundtrip.md for the same one-datagram timeout under CI load.
Disable it and register it with that quest, per the flaky-test rule. The quest keeps the investigation and the re-enable.
quest land watch: the merge queue removed this pull request at 5ff394e because its merge_group build failed (failed_checks).
The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.

✅ No new issues found. The merge of main resolves the queue conflict without losing either side's changes.
Reviewed changes
Merged origin/main at 0672ad56c: the branch picked up main's newer commits; no policy code changed in the merge.
Resolved the queue conflict in the quest graph: quest/m1/session-policy/connect.md stays deleted, its link is dropped from quest/m2/recut-held.md, and quest/m5/uring-cluster-dial.md carries the updated reconnect note after main's m3 → m5 file move. Quest is green.
Adapted the moq-tokio tests to main's origin API: the three create_broadcast/announce sites in rs/moq-tokio/src/connection.rs now use origin.route(name, RouteOptions::default()), matching main's text verbatim.
Kept both datagram quarantine entries: sh/gh/test-inventory.allow lists main's datagrams_cross_a_default_connection alongside this PR's requested_datagrams_cross_a_default_connection, and both tests carry #[ignore].
I verified that git diff fc3a87f..20a8110 equals main's own 1c140ac9b..0672ad56c tree delta apart from the intended connect.md deletion and the dropped recut-held link, so the resolution dropped no upstream change and the PR's diff against main is unchanged from the previously approved head. All prior Pullfrog threads are resolved. Check was still running on this head at review time; the PR body reports just check origin/main passing on 20a811002.

#7904 ignores requested_datagrams_cross_a_default_connection after it
missed its datagram in this PR's Check, the plain test's symptom. The
datagram quest re-enables both.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The current test starts next() only after group 3 arrives. It can miss an early result or a lost wakeup in the FFI reader. The mux test does not exercise Polled::wait.
Poll a read before writing group 3, assert that it is pending, then check that the same read wakes and returns group 3 before finishing the track. A first-poll handshake and a recording waker can do this without paused time.

Re CodeRabbit's nitpick on rs/moq-ffi/src/media.rs:1620 (review): declined. The removed assertion (5ff394e75c) timed a read that polls on the FFI runtime against the test's paused clock, so it measured real time. A pending-then-wake read at the FFI boundary is already covered where it lives:
Polled::wait, which every media next() parks in, is tested directly by polled_one_waker_state_wakes_every_parked_call (rs/moq-ffi/src/ffi.rs:1550), together with polled_is_busy_until_a_parked_call_is_dropped and polled_cancel_drops_the_state_and_ends_a_parked_call.
The start reach's wait for a group covering the warmup is tested on one clock by moq-mux's start-reach tests, as the doc comment on raw_media_catalog_warmup_reaches_the_subscription notes.
What this test checks is that the warmup widens the subscription and keeps group 3, and it still asserts that.
quest land watch: the merge queue removed this pull request at 99aaaf5 because its merge_group build failed (failed_checks).
The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.
The CI audio playout-delay timeout did not reproduce: all 125 Python tests passed both before and after merging base. No evidence ties that local, connection-free test to this PR’s reconnect changes, so blame is unset. The pinned head also had a moq-net doctest compilation error already corrected on base; a plain, conflict-free base merge incorporates that correction. No additional source edits were made. Rust tests, integration tests, and doctests pass with four test threads. Two unchanged pool-debt memory-accounting tests failed at default Cargo concurrency and passed with four threads.

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.
The queue log reports a TimeoutError waiting for the fixed audio consumer in test_audio_consumer_reports_its_playout_delay. The unchanged pinned head passed all 125 Python tests, including that test, after rebuilding the native bindings with testing,openh264. All 4426 affected Rust tests passed under cargo nextest (37 skipped). No evidence connects the local audio timeout to this PR's reconnect changes, so no PR is blamed. The timeout appears intermittent and should be followed up. No source or branch changes were made. An initial cargo test run had two pool-accounting failures in its shared process; both passed with CI's process-isolated nextest runner.

Completes Connect policy in moq-net, part of the session policy epic.
Client connect policy now lives in moq-net as

Attemptit asks for and reportsconnectedorfailedwith aVerdict. The machine watches the live session's close and GOAWAY itself and returnsActions (Dial,Abandon,Migrating,Retired,Offline,Retrying,Wait,Done). moq-tokio'sConnectionloop now drives it. moq-tokio keeps the dialing (DNS, Happy Eyeballs, sockets, TLS, the QUIC/WebSocket race), its CLI config, theMonitorstate it publishes, bandwidth forwarding, and spawning.One connect path with #7607
moq-dev/moq#7607 landed first (maintainer's pick, 2026-11-05) and turned the handshake behind
moq_net::Client::connect(now, transport)into the privateConnectpoll machine. The two layer rather than overlap:Reconnectdecides which address to dial and bounds each dial, and the caller's dial runs the transport and thenClient::connect, whoseConnectmachine is the only handshake. AnAction::Abandonat the deadline drops the dial, handshake included.Reconnectsits behind moq-net'sasyncfeature, likeSessionandClient, since it watches sessions.Public API and wire impact

The quest expected one, and feat!: generate async wrappers behind default-off async features #7607 has since brokenClient::connectanyway, so the question was whether the connect deadline or the policy should now move intoClient/Connect. It should not: the deadline must cover the transport dial too, whichClient::connectnever sees, so a deadline there would still need the caller to bound the dial separately. The alternative,Reconnectowning the handshake (the caller hands it each transport and it runsConnect, then hands back the driver to spawn), adds a handshake phase and a driver-handoff action toReconnect, whileconnect_webrtcand moq-tokio's QUIC/WebSocket race would still callClient::connectdirectly.

A pre-established peer has no address to walk; moq-tokio becomes a thin shell owns routing it through moq-net.js/net's connection behavior is untouched.Retryingthat follows a failed or abandoned dial as a failed walk, resets the count on connect, and replaces the port at the second failure, before the backoff instead of before the next walk, which has the same effect. Each dial owns a clone of theClient, so the port can change while no dial is in flight. Its "explicit shutdown" exit became aVerdict::Fatalfor a failed QUIC dial on a closed client.

test rs: moq-ffimedia::read_tests::raw_media_catalog_warmup_reaches_the_subscriptionpanicked with "the start waits for a group covering the warmup". It is a pre-existing flake from moq-dev/moq#7864, not this PR's code, and no open PR fixed it.Cause: the test ran on a paused tokio runtime and stamped each group's arrival on that runtime's clock, but moq-ffi's
Polled::pollenters the FFI root runtime, whose kio clock is the shared real one. A paused runtime counts from its own first reading, so the reader's "the newest group landed a whole reach ago" fallback compared two timelines and fired once the process had run 500 ms of real time (the CI run took 0.77 s). A 600 msstd::thread::sleepbefore the writes reproduces it every time.Fix: the test writes all three groups, newest first, before the first read, so the start decision reads no clock. It still proves the warmup reaches the start: dropping the warmup from moq-mux's start skip fails it with
[4700000, 5000000]. moq-mux's start-reach tests (the_start_waits_for_an_earlier_group_when_the_live_edge_arrives_firstand siblings) keep covering the timed wait on a single clock. It passes with the 600 ms stall and in a 100-run stress loop.Requested datagram quarantine
This PR keeps
#[ignore]onmoq-ffi::test::requested_datagrams_cross_a_default_connection(pullfrog's 14eb297612), plus itssh/gh/test-inventory.allowentry. CodeRabbit asked for both to be removed, since ffi-datagram-roundtrip.md quarantines only the plain sibling. It stays because of this evidence:FAIL [10.157s], a panic atrs/moq-ffi/src/test.rs:6111after the single appended datagram missed the 10 s wait. This is the same symptom as the plain sibling's failure on moq-dev/moq#7914.quest gate nix develop --command just rs test -p moq-ffi --lib -E 'test(requested_datagrams_cross_a_default_connection)' --run-ignored all --stress-count 100passed 100/100 on an idle host. That points to a failure under load, not one this PR's code causes on every run.Removing the ignore would bring back a CI failure that has already been observed. The quest's prose ("its requested siblings ... remain enabled") is out of date for this case. Its Goal already names the
