Finishes quest m1/auth/issuer (its file is deleted in this PR). An auth handle now outlives its session, so a route naming a token keeps it across a reconnect, in both Rust and JS.

What changes

moq-net (rs/moq-net/src/auth.rs, client, session, goaway, lite/ietf drivers)

• auth::Handle is session-independent: Handle::new() plus Client::with_auth(handle). Each session built on it presents every token the handle holds, so a Route naming one of its Auths keeps it across a reconnect with no re-add or re-announce.
• A handle backs one active session at a time, plus any draining after a GOAWAY. Attaching another while one is active fails with Error::Duplicate.
  • A draining lite session opens no new streams, so a token added after the GOAWAY rides only the successor.
  • A token still unanswered on the draining session can still be answered there, and its issued grant stays open.
  • A draining session's verdict defers to an active session that still presents the token, even one mid-retry with no grant.
• Auth::grant() and Handle::grant() follow the newest open session, and are None while disconnected.
• Only the peer's verdict ends a token: a non-transient refusal, Unsupported, or a clean close after a grant. A session ending does not.
• On lite, a transient refusal (Internal, TooManyRequests, Timeout) is presented again after a backoff of 1s doubling to 30s. moq-transport AUTH_ERROR has no transient code, so its presenter has no retry loop. This logic moved here from moq-tokio.
  • Through the backoff the token counts as unanswered, so a publication or request it might cover waits instead of being judged unauthorized.
  • The peer already replied, so a retry stream lost before its reply is not Unsupported, and a shared handle keeps the token.
• Handle::abort(err) ends a handle; a handle a session creates for itself still ends with it.
  • That handle has no successor: any end of a token's stream is final, and a token added after its GOAWAY fails with GoingAway.
• Handle::add resolves with (Auth, Answer): Answer::Granted when the peer granted the token on its AUTH stream, Answer::Requests when only the requests naming it carry it (moq-transport without AUTH). The answer is fixed once given, so it holds after the session drops.
  • moq-ffi refuses only an Answer::Requests token, instead of inferring that from a missing grant, which a dropped session also reads.
  • js/net has no such consumer, so it keeps add() resolving with the token alone.

moq-tokio

• Connection::auth() returns moq_net::auth::Handle, and every dial is built on it. Aborting it ends the loop at its next reconnect.
• The connection::auth module and its replay loop are deleted.

js/net mirrors the design:

• Auth.Handle is a class.
• connect({ auth }) builds a session on one.
• A reconnecting Connection owns one as connection.auth.
• Auth.Duplicate is new.
• Auth.None is removed; nothing returned it.
• Transient refusals retry with the same backoff.
• A moq-transport GOING_AWAY reply is no verdict, as in Rust, so a shared handle's token survives it.
• Aborting connection.auth gives the loop up at its next reconnect.
• A second requests() throws Auth.Duplicate.

Consumers and docs

• moq-relay:
  • The benches are updated.
  • Two auth/refresh.rs tests now expect the retry instead of an error.
• Docs no longer tell a reconnect to re-add the token and re-announce: doc/concept/{moq-lite,standard}.md, doc/lib/{js/net,rs/moq-net}.md, doc/bin/relay/auth.md.
• MIGRATE.md entries are added for moq-net, moq-tokio and js/net.

Tests

• moq-net integration:
  • a_shared_handle_presents_its_token_on_every_session
  • a_handle_backs_one_active_session, including the draining cases
  • lite_07_presents_a_transiently_refused_token_again
  • lite::session::tests::a_lost_retry_keeps_a_shared_token
  • moqt_{16,22}_route_auth_survives_a_reconnect
• moq-net unit tests:
  • only_a_verdict_ends_a_shared_token
  • the_answer_outlives_its_session
• moq-ffi a_grant_survives_its_session_dropping_before_add_returns: fails if add infers request-only from a missing grant.
  • a_transient_refusal_backs_off
• moq-tokio a_token_is_presented_on_every_session:
  • Runs in about 0.2s at about 190MB peak RSS, so memory is bounded.
  • The earlier OOM was the build on a loaded machine.
  • The test also failed to compile under tcp because of a shadowed token; that is fixed.
• js/net auth.test.ts:
  • A shared handle presents its token on every session.
  • A handle backs one active session.
  • A lite-07 transient refusal is retried, on a mocked clock.
  • A shared token whose retry stream is reset is kept.
• js/net migrate.test.ts: the connection's tokens ride every session across a GOAWAY.

Decisions

The maintainer confirmed all six, each the ✅ option this PR implements.

1. Server equivalent of with_auth. A server's sessions are separate peers, so a shared handle would merge their authorize() and requests().
   • ✅ (a) Skip it until a consumer needs it.
   • (b) Add Server::with_auth.
2. Retry pacing. moq-tokio previously reused its configurable reconnect backoff.
   • ✅ (a) Fixed at 1s doubling to 30s.
   • (b) Make it configurable on Handle.
3. Error when a handle already backs an active session.
   • ✅ (a) Reuse Error::Duplicate (JS Auth.Duplicate).
   • (b) Add a dedicated variant.
4. Setup or handle token on moq-lite without AUTH. ✅ present succeeds and the token ends with Unsupported. add() still fails at once with Unsupported.
5. Single-session add() on a transient lite refusal. ✅ It retries instead of returning the code, matching the replay loop it replaces.
6. JS Connection.auth on a pooled connection. ✅ Expose it as a Getter<Auth.Handle | undefined> that follows the URL, like origin.
   • A pooled connection's handle is shared by every user of that URL.
   • A private loop keeps one handle across URL changes, so its tokens go to the new relay.

Settled while addressing reviews on c6f331e, each the recommended option:

7. A draining session's late refusal. ✅ It defers to any active session still presenting the token, rather than only one that holds a grant right now, so a successor mid-retry keeps it.
8. A token waiting out a transient refusal. ✅ It counts as unanswered, as on its first presentation. A request it might cover parks through the backoff rather than failing fast, and enforcement no longer closes the session as Unauthorized.
9. An aborted connection handle. ✅ The reconnect loop ends with the abort's error at its next reconnect. It does not tear down the live session at once.

Checks

• Passed:
  • At 587a5d1, after merging main: just check (all modules but nix flake check, which fails locally on the runner-image user-namespace limit). Before that merge, at 7d894b0: cargo nextest -p moq-net -p moq-tokio -p moq-relay -p moq-ffi --all-features (4284 tests), clippy with all and no default features, cargo fmt, bun test, biome and tsc in js/net (2669 tests), and just test interop --all (127 passed).
  • At a4c2e3c: the same Rust suite (4283 tests), clippy and cargo fmt.
  • At c7d069e: cargo nextest -p moq-net -p moq-tokio -p moq-relay -p moq-ffi --all-features (4282 tests), moq-net clippy with all and no default features, cargo fmt, and bun test, biome and tsc in js/net (2668 tests).
  • At 3286e29, after merging main at 1c72130: just check (all modules but nix flake check, which fails locally on the runner-image user-namespace limit), cargo nextest -p moq-net -p moq-tokio -p moq-relay -p moq-ffi --all-features (4281 tests), and the moq-net no-default-features clippy lane. bun test in js/net (2648 tests) at ffa3394; the later merge touched no auth JS.
    • The merge ports moq-dev/moq#6167's tracks.rs tests and main's new lite listing tests to auth::Link, as in moq-dev/moq#6177.
    • Main's ManualClock.advance now returns a promise, so the PR's JS tests await it. Auth::id is test-only rather than async-only, since a test outside the async gate uses it.
    • A private JS Connection now builds one reload loop per version list, as on main, so a version change gives it a new auth handle, as a pooled connection already did. A URL change keeps the handle.
  • just check origin/main at 0c7acdd, after merging main at e76b4b3. nix flake check fails locally only on the runner-image user-namespace limit (unshare: write failed /proc/self/uid_map), so the steps after it ran by hand: 8058 Rust tests, the JS suites (2483 in @moq/net), py test, and the markdown, shell, toml, nix, justfile and gh lints.
  • just check origin/main at 4cf66d6, after merging main: 7815 Rust tests, the moq-net no-default-features lane, and the full JS suite.
  • just js check-changed and the @moq/net auth tests at c0b800c.
  • Codex review of c0b800c: no findings.
  • GitHub CodeQL on bd0f1c5.
  • cargo nextest -p moq-net -p moq-tokio -p moq-relay.
  • quest check.
• Flaky and unrelated: moq-cli export::redundant_importers_switch_through_bufferbloat_on_lite_07.
  • Failed 2 of 4 loaded just check runs and passed 3 of 3 runs on its own.
  • Already tracked on main by quest/m1/test-flakes-2/redundant-failover-drift.md.
• just test interop --all at a4c2e3c: all 127 checks passed (Rust, Python, Go, C++, JS and browser publishers and subscribers, including the denied-token cases), since moq-ffi changes here.
• Main's lite/subscriber.rs test fixture did not compile after moq-dev/moq#6143. The merge carries the same one-line fix as moq-dev/moq#6223, so the two merge cleanly.

Public API / wire

Breaking, with no wire change:

• moq-net
  • Handle::new() creates a session-independent handle.
  • New: Client::with_auth, Handle::abort and auth::Answer (Granted, Requests).
  • Handle::add resolves with (Auth, Answer) instead of Auth.
  • grant() follows the live session.
  • Attaching a second active session fails with Error::Duplicate.
• moq-tokio
  • Connection::auth() returns moq_net::auth::Handle.
  • The connection::auth module is removed.
• js/net
  • Auth.Handle is a class.
  • New: connect({ auth }), Connection.auth and Auth.Duplicate.
  • Auth.None is removed.
  • Established.auth returns the session's handle.
  • requests() called twice throws Auth.Duplicate.

Follow-ups

• Server::with_auth, once a consumer needs it (decision 1).
• Re-present a shared handle's token on the live session when its stream is lost without a verdict, with the retry backoff on both wires. Today it waits for the next session (mriise's review, bug 1, raised again by Codex on 081b756). No quest tracks it yet.

Walkthrough

The change adds reusable authentication handles in JavaScript and Rust. Tokens can persist across sessions and be presented after reconnects. Session links track session-specific grants, token presentation, and draining state. Transient moq-lite refusals retry with exponential backoff from 1 to 30 seconds. Connection, FFI, Tokio, relay, protocol, test, migration, and documentation code now uses or describes this shared model.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to dfc99

The reusable auth handle changes now handle aborted connections, closed sessions, transient refusals and redirect token forwarding as intended. No concrete merge-blocking issue remains in the reviewed change.

[mriise]

Read-only review of 4cf66d6d6. I ran no tests. The happy path meets the quest: routes keep their Auth across a reconnect without a re-add or re-announce, and there is no wire change. The findings are at the edges.

Bugs

1. A token that ends without a verdict leaves add() and closed() pending.

Link::ended (rs/moq-net/src/auth.rs:1036-1066) records a non-verdict end only on the link's slot. state.end_token runs only for a verdict. Auth::poll_answered (auth.rs:1344) and Selector::ended read the handle-level state.tokens[id], which stays unset.

• Per-session handle after a GOAWAY: session.auth().add(t) ends with Error::GoingAway (lite/session.rs:583-586, and the ietf loop). add() then stays pending until the drained session closes. Before this PR it rejected at once.
• ietf stream reset before an answer: Present::run returns Error::Stream(_), which is not a verdict, so Rust add() hangs. JS maps the same case to Unsupported and rejects (auth.test.ts:869).
• Shared handle, stream lost mid-session: a lite reset with a non-Cancel code after a grant, or a failed poll_open, leaves the token unpresented on the live session. grant() reads None, and closed() waits for a reconnect that may never come.

Suggested fix:

• When the handle is bound to one session, make any end final (end_token).
• For a shared handle, re-queue the token on the live link, or end it.
• A Rust test for the ietf reset case, mirroring the JS one, would pin this.

2. JS presents on a draining session; Rust does not.

Rust refuses new AUTH streams after a GOAWAY, and the PR says "a token added after the GOAWAY rides only the successor".

JS does not. HandleState.add offers to every session (js/net/src/auth_session.ts:231). AuthSession.offer (:586) and the retry in #run check #closed but never #draining. If the draining peer resets that stream before answering, #run maps the StreamError to Unsupported. That is a verdict, so the token ends on the successor too.

Suggested fix: have offer and the post-backoff retry skip draining sessions, and add a JS test for a token added after a GOAWAY.

Risks

3. abort on a connection-owned handle quietly breaks reconnects.

• moq-tokio Connection::auth(), JS Reload.auth and pooled Connection.auth all expose abort.
• After an abort, Link::attach and JS vacant() reject every later connect. They do so only after dialing the relay, while the current session keeps running.
• With pooling, one consumer of a URL breaks reconnects for every other consumer of it.

Consider returning a view without abort, or having the loop close loudly when its handle ends.

4. A clean close after a grant counts as a verdict (auth.rs:1046-1049).

• A server that drops its Issued before the transport closes ends the client's token on every future session.
• The moq-tokio test a_token_is_presented_on_every_session already has to keep issued alive past session.abort to avoid this.
• A natural per-session server task that drops Issued on GOAWAY drain would trigger it.

Consider treating only an explicit AUTH_ERROR as a verdict, or documenting the requirement on acceptors.

5. Docs.

• Requests::next / poll_next still say "None once the session ends". With a shared handle it is the handle's end.
• doc/lib/js/net.md says "A Connection's auth handle", but pooled Connection.auth is a Getter<Handle | undefined>.

Questions

1. A JS reload loop keeps one handle across URL changes, so a token minted for relay A is presented to relay B. Is that intended, or should a URL change abort the handle?
2. Handle::authorize and the acceptor queue span sessions, so a limit set for one peer carries over to the next. That is fine for the same relay. Is it intended after a GOAWAY redirect to another one?
3. Rust wraps the ietf presenter in the retry loop (ietf/auth.rs:~298), but from_code never yields a transient code there. Delete the loop, or keep it for parity with lite?
4. JS Handle.requests() throws a plain Error where Rust returns Error::Duplicate. Should JS throw Auth.Duplicate now that it exists?

@codex review

Merged origin/main after moq-dev/moq#6137. moq-tokio's connection::auth stays deleted, so rs/moq-ffi/src/auth.rs collapses its session/connection enum onto the one moq_net::auth::Handle, as #6137 decided for whichever PR landed second. The Unsupported check for a token nothing carries now applies to client sessions through that same path. quest/m1/auth/bindings-polish.md drops its FFI bullet. Main's new subscriber revocation tests build their handle with auth::Link.

3ed5932 fixes the three findings on 73bc832. A token added after a GOAWAY is now offered only to active sessions, in Rust and JS. A JS transient retry stops once its session drains. A JS successor's grant takes over as soon as it attaches.

587a5d1 removes Auth::in_band(). Handle::add now resolves with (Auth, Answer), where Answer::Granted means the token was granted on its AUTH stream and Answer::Requests means only requests carry it. moq-ffi refuses only Answer::Requests, so a token granted just before its session drops is no longer reported as Unsupported. A regression test covers that race. Main is also merged.

Three findings on ce63eb0, each new in this PR. I checked earlier threads and your reply to my last review, so already-settled points are left out.

On a session's own handle, a token waiting out a transient refusal ends here with Error::Cancel if the session drains first: reopen returns None once the link is inactive, and Link::ended treats any end as a verdict because the handle is bound. moq-ffi's MoqAuthToken::closed maps Cancel to Ok(()), which reads as "the peer ended the grant cleanly." The PR says a token added to a session's own handle after its GOAWAY fails with GoingAway. Should this path return Error::GoingAway instead, so a draining session never reads as a clean close?

When the loop gives up on a non-MoqNet error (a failed connect, or the reconnect budget running out), or the last Connection is dropped, the handle is aborted with Cancel. moq-ffi maps that to MoqAuthToken::closed() -> Ok(()), the same result as a peer cleanly ending the grant. On main, the connection path went through map_closed_error, so closed() returned Connect { reason } or Closed, and ending_the_connection_withdraws_a_retained_token_handle asserted is_err(). Could the loop abort with an error that survives the mapping, like moq_net::Error::Transport or a dedicated stopped error, or could moq-ffi tell the connection's end apart from a peer's clean close?

Stale now that MoqSession::auth on a client wraps the connection's handle. grant_changed errors when the handle ends, not when a session does. MoqAuthToken::closed (line 148) still says "or the session's close", but a reconnect no longer ends a connection token: it ends on the peer's verdict or the connection's end.

Stop dequeuing AUTH tokens after a local GOAWAY

When a token is queued just before this side sends GOAWAY and the driver polls afterward, this predicate still dequeues it because it checks only closed. In the moq-transport presenter, run_present then guards only going_away.is_set(), which represents a received GOAWAY, so the draining predecessor can open a new AUTH request while the shared token is also offered on its successor. Gate dequeueing on link.active() or perform the same Link::active check used by the lite presenter.
