fix(net): answer a draft-18 TRACK_STATUS followed at once by a FIN - #7439
On draft 18 a requester FIN withdraws a request (request_stream::fin_cancels), so a TRACK_STATUS followed at once by a FIN is reset with CANCELLED instead of answered. Nothing can follow a TRACK_STATUS, so a requester may FIN right after it, and moxygen does. A moq-lite viewer behind moq-relay with a moxygen relay upstream then never subscribes. Fixes#7438, which has the reproduction.
Approach
A FIN now only ends a TRACK_STATUS requester's input, on every draft; a reset or STOP_SENDING still withdraws it.
Rust: poll_cancel, poll_withdrawn, until_withdrawn and resolve take the FIN rule as fin_cancels: bool instead of the version. Every caller passes fin_cancels(version), except serve_track_status_stream, which passes false.
JS: RequestStream takes { finCancels }, which runTrackStatusRequest sets to false.
Docs: doc/concept/standard.md no longer says a refused TRACK_STATUS still subscribes, and notes when a requester's FIN cancels.
Impact
Wire: on draft 18 a TRACK_STATUS is no longer withdrawn by a FIN alone, only by a reset or STOP_SENDING, so a FIN'd one holds its lookup and request ID until it is answered. Every other request is unchanged.
Public API: none.
release refuses TRACK_STATUS, so there is nothing to backport.
Alternatives
Drop the draft-18 FIN cancel for every request except SUBSCRIBE_NAMESPACE and SUBSCRIBE_TRACKS, as draft 18 §6.1 has it. Not done here, because moq-dev's own draft-18 requesters cancel by FIN (JS RequestStream.cancel(), for one). Decided on this PR: the TRACK_STATUS-only scope.
Through moqx the next hop still fails until openmoq/moxygen picks up facebookexperimental/moxygen aaa50a77 (Maybe close on disconnected element. #264): its TRACK_STATUS_OK carries GROUP_ORDER. Nothing to do here.
Validation
New tests, Rust track_status_finished_at_once_is_answered and JS "TRACK_STATUS finished at once is answered on every draft", fail without the fix. requests_withdrawn_while_resolving_release_their_demand now withdraws its TRACK_STATUS with a reset.
moq-net 2701 and @moq/net 2693 tests pass. cargo clippy -p moq-net -p moq-relay -p moq-cli --all-targets -- -D warnings, rustfmt, biome and tsc are clean.
sh/markdown.sh check passes.
just ci upstream/main on macOS, host toolchain, no Nix: shell, toml, nix, justfile, large_files and drill pass. rs and rs_shapes stop on GStreamer and the Linux-only moq-uring, js on a missing wasm-bindgen, markdown on a @moq/libav build that needs Nix, and gh on bench/relay.test.py, which fails the same way without this change.
End to end with moqx v0.3.6-92-gb6e6b831 on draft 18: a moq publisher built from this branch answers moqx's TRACK_STATUS.
Review
Local quest review (Codex, gpt-6.1-sol, medium effort, run by the maintainer's session with --root from outside this checkout) against origin/main at head cc1130c1dcd0a6426ec717919f2d4165fd30e043: the land fixer's base merge and its TRACK_STATUS FIN test adaptation (f721a41), which GitHub refused to let the App push because the merge touches a workflow, plus a clean merge of current main. Round 1, 0 findings. The land gate runs the checks; this fork's code was not run locally.
Head 4b3cd125f0 is a conflict-free merge of origin/main (59e12a5bb9) onto that reviewed head, so the review carries over. Main's changes to the touched ietf files (a coop budget in session.rs, the clock RNG in publisher.rs, a stitch test in subscriber.rs) add no new caller of poll_cancel, poll_withdrawn, until_withdrawn or resolve. quest check passes, run with an installed quest and --root from outside the checkout.
Land ejection, 2026-11-01 20:44Z: the batch with moq-dev/moq#7370 failed test rs on moq-tokio::integration backend::quic_client_close_drains_finished_track ("subscribe failed: Unroutable"). That test is a flake and this PR did not cause it. It runs moq-lite (moq-lite-07-wip, rs/moq-tokio/tests/integration/backend.rs:801), and this PR changes only ietf request handling. quest: pin the restart a follower gets when the serving epochless route leaves #7370 touches only quest files. The land fixer reran the full moq-net and moq-tokio nextest (3788 passed, the test included) on the merged batch.
CodeRabbit's thread about an extra handle_stream argument was already fixed by f721a41, so it was answered and resolved. Pullfrog's failing check is a billing outage and was ignored.
On draft 18 we read a requester FIN as withdrawal of the request, so a
TRACK_STATUS followed at once by a FIN was reset with CANCELLED instead
of answered. Nothing can follow a TRACK_STATUS, so a requester may FIN
right after it, and moxygen does.
A FIN now only ends a TRACK_STATUS requester's input, on every draft, in
the Rust and JS publishers; a reset or STOP_SENDING still withdraws it.
The draft-18 FIN cancel of the other requests is unchanged, since our own
draft-18 requesters cancel by FIN. The FIN rule is passed to the request
stream watches, resolve and until_withdrawn instead of the version.

Maintainer decision (2026-10-31) on this PR's open question: keep the TRACK_STATUS-only scope. Please mark it ready for review. It's tracked by quest/m1/interop-coverage/draft18-status-fin.md (moq-dev/moq#7441), which also wants doc/concept/standard.md:31 fixed. Its last clause says a reader whose publisher refuses TRACK_STATUS "still subscribes", which is stale for query-only and fetch-only readers. Including that doc fix here is welcome.
…only ends input
The fetch-only clause still said a reader whose publisher refuses
TRACK_STATUS as NOT_SUPPORTED subscribes anyway. That fallback was
removed, so any refusal now fails the reader's request. Also note when a
requester's FIN cancels a request.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
No actionable bugs found in the changed code. The TRACK_STATUS-only FIN exception is a well-scoped interop fix: both implementations keep the lookup alive after FIN while retaining reset/STOP_SENDING cancellation, and the other request types preserve their existing draft-dependent behavior. Passing the FIN policy explicitly is sufficient; a broader cancellation redesign is unnecessary here. The added FIN regressions and retained withdrawal tests target the relevant lifetime distinction, and the documentation corrects the refused-status behavior.
Verification: static GitHub review of the diff and relevant request-stream, publisher, requester and test code, including an independent Rust pass. I did not run tests, builds, or the moxygen reproduction.

Rust: fin_cancels becomes a parameter.request_stream::poll_cancel, poll_withdrawn, publisher::until_withdrawn, and publisher::resolve now take fin_cancels: bool instead of a Version; every caller passes fin_cancels(self.version) except serve_track_status_stream, which passes false.
JS: RequestStream option. The constructor takes { finCancels?: boolean }, defaulting to finCancels(session.version) and stored as #finCancels; runTrackStatusRequest passes { finCancels: false }.
Tests. New Rust track_status_finished_at_once_is_answered and JS "TRACK_STATUS finished at once is answered on every draft"; the existing withdrawal test now withdraws its TRACK_STATUS with a reset.
Docs.doc/concept/standard.md documents the requester-FIN rule and corrects the stale refused-TRACK_STATUS claim.
The poll_cancel branch (Poll::Ready(Ok(())) if !fin_cancels => *finished = true) correctly marks the requester's input done without cancelling, and a reset or STOP_SENDING still withdraws via the reader error / writer.poll_closed. The remaining inline fin_cancels(self.version) sites are SUBSCRIBE_NAMESPACE / SUBSCRIBE_TRACKS, which draft 18 does treat as FIN-cancelling, so they correctly stay as-is. Hardcoding false for TRACK_STATUS is version-correct since draft 20+ is already false. No public API or wire-spec change.

Walkthrough
Request-stream cancellation now uses an explicit FIN policy in Rust and JavaScript. Publisher handling preserves TRACK_STATUS requests after requester FIN, while other request paths use draft-specific FIN cancellation. Tests cover TRACK_STATUS completion after FIN while resolution is pending and after FIN on supported drafts. The documentation updates its account of TRACK_STATUS refusal and requester-FIN behavior.

Explanation
[#7438] requires that a TRACK_STATUS followed by a requester FIN is answered on every draft. Reset and STOP_SENDING must still withdraw it. Other requests keep their behavior. Rust: rs/moq-net/src/ietf/request_stream.rs (read in the whole-PR diff) replaces the Version argument of poll_cancel and poll_withdrawn with fin_cancels: bool. Both functions use that flag for the FIN rule. fin_cancels(version) still returns true only for Draft18. The earlier review found that serve_track_status_stream in publisher.rs passes false, that resolve receives the same flag, and that the test track_status_finished_at_once_is_answered checks TRACK_STATUS_OK, a clean FIN, and no reset on all drafts. I did not re-read publisher.rs at this head, so that wiring rests on the earlier review. JS: js/net/src/ietf/request_stream.ts (read in the whole-PR diff) adds a finCancels option that defaults to the draft rule. cancel(), read-ahead end handling, and the peer-FIN handling all use the stored value. The runTrackStatusRequest wiring of finCancels: false in js/net/src/ietf/publisher.ts could not be read; the blob was unavailable. That part rests on the PR summary. The Rust path named in the reproduction is the moq-net IETF publisher, and that path is covered, so the JS gap does not block this verdict. The moqx GROUP_ORDER issue is outside this PR, as #7438 states.
Full details: Out of Scope Changes check
Explanation
The Rust change in request_stream.rs replaces the version parameter with fin_cancels: bool. Each existing caller passes fin_cancels(version), so behavior for other requests is unchanged. This refactor supports the TRACK_STATUS-only FIN exception required by [#7438]. The JS request_stream.ts change adds an option that defaults to the existing rule. Its only non-default caller is the TRACK_STATUS path, which is in scope. The doc/concept/standard.md edits correct the stale refused-TRACK_STATUS wording and document the requester FIN rule. This supports the change in scope. The deletion of quest/m1/interop-coverage/draft18-status-fin.md and its README entry is administrative. The maintainer reports the follow-up as complete. No change implements the separate moqx GROUP_ORDER fix, so no unrelated code appears.

Merged main into the branch. Resolved the doc/concept/standard.md conflict by keeping main's SUBSCRIBE_TRACKS refusal text and reapplying this PR's two edits: the refused-TRACK_STATUS history sentence and the "A requester's FIN" bullet.
Finished the quest. Deleted quest/m1/interop-coverage/draft18-status-fin.md and dropped its Required entry from quest/m1/interop-coverage/README.md.
The fin_cancels threading, JS finCancels, and the new tests are byte-for-byte the same as the previously reviewed 232fbd0; the merge brought no code change. The resulting doc/concept/standard.md reads coherently with main's #7236 edits and the quest README no longer links the deleted file.

-- The fix is in [moq-dev/moq#7439](https://github.com/moq-dev/moq/pull/7439), an external contributor's draft that allows maintainer edits, with exactly this scope. Rust passes `fin_cancels: bool` through `poll_cancel`/`poll_withdrawn`/`until_withdrawn`/`resolve`, and `serve_track_status_stream` passes `false`. JS `RequestStream` takes `{ finCancels }`. Review it, mark it ready, and land it. Push the doc fix below onto it, or land it as a follow-up commit.
-- #7423 asked that a TRACK_INFO behind a publisher refusing TRACK_STATUS fall back to subscribing:
- - ✅ Won't fix + doc fix: publishers must answer TRACK_STATUS. moqxr should implement it, which the maintainer called "really not hard". This matches the 2026-10-29 rejection of blind subscribing on [moq-dev/moq#7187](https://github.com/moq-dev/moq/pull/7187).
- - Fallback subscribe
- - Keep open, defer
-- Doc: `doc/concept/standard.md:31` ends with "a reader whose publisher refuses `TRACK_STATUS` as `NOT_SUPPORTED` still subscribes". That is left over from the fallback that [moq-dev/moq#5991](https://github.com/moq-dev/moq/pull/5991) removed. Reword it so only a subscribing reader still subscribes, while a query-only or fetch-only reader fails, as `a_refused_track_status_never_subscribes` (`rs/moq-net/src/ietf/subscriber.rs`) pins.
-- Not here: moqx's GROUP_ORDER parameter in TRACK_STATUS_OK, which draft 18 refuses. That is upstream moxygen's fix, facebookexperimental/moxygen#264, tracked by [Moxygen pin bump](/quest/m1/moxygen-pin-bump.md).

Re-applied the fix through main's new Resolve machine. Merging current main (ff6c72d, 094090b) brought the Resolve state machine the branch predated. Resolve now carries a fin_cancels field and forwards it to poll_withdrawn at both waits (origin lookup and broadcast lookup), so a TRACK_STATUS resolve still survives a requester FIN.
request_stream takes the rule as a bool.poll_cancel and poll_withdrawn now take fin_cancels: bool instead of a Version; every caller passes fin_cancels(self.version) except serve_track_status_stream, which passes false.
Test migrated to main's clock.track_status_finished_at_once_is_answered now uses #[kio::test] / kio::clock::timeout; the withdrawal test still withdraws its TRACK_STATUS with a reset.
Docs. The doc/concept/standard.md requester-FIN bullet and refused-TRACK_STATUS history edit are preserved through the merge (main's Timing bullet came in as base context).
I traced the fin_cancels = false path end to end for TRACK_STATUS: poll_withdrawn ignores a reader FIN at both Resolve waits while still resolving on session close or reset, and poll_cancel marks the requester finished on a FIN without cancelling, so the request is answered normally. All other request kinds pass fin_cancels(self.version), keeping their prior behavior byte-for-byte. No prior Pullfrog review threads were open, so none needed retiring.

fixer result written
Main's #7306 keeps a cleanly finished subscription's join in `Retain`, bounded by
its request grant and gate. It now holds the request's `RequestBinding` and the
gate the subscription was held to (the named one once it named a token), so a
token named by an update still bounds the retained join.
Main's #7439/#7296 made `poll_withdrawn` and `until_withdrawn` take
`fin_cancels`; `admit_request` takes it too, `false` for TRACK_STATUS as main's
TRACK_STATUS path does, `fin_cancels(version)` elsewhere.

Problem
On draft 18 a requester FIN withdraws a request (
request_stream::fin_cancels), so a TRACK_STATUS followed at once by a FIN is reset with CANCELLED instead of answered. Nothing can follow a TRACK_STATUS, so a requester may FIN right after it, and moxygen does. A moq-lite viewer behind moq-relay with a moxygen relay upstream then never subscribes. Fixes #7438, which has the reproduction.Approach
A FIN now only ends a TRACK_STATUS requester's input, on every draft; a reset or STOP_SENDING still withdraws it.
poll_cancel,poll_withdrawn,until_withdrawnandresolvetake the FIN rule asfin_cancels: boolinstead of the version. Every caller passesfin_cancels(version), exceptserve_track_status_stream, which passesfalse.RequestStreamtakes{ finCancels }, whichrunTrackStatusRequestsets tofalse.doc/concept/standard.mdno longer says a refused TRACK_STATUS still subscribes, and notes when a requester's FIN cancels.Impact
releaserefuses TRACK_STATUS, so there is nothing to backport.Alternatives
RequestStream.cancel(), for one). Decided on this PR: the TRACK_STATUS-only scope.Follow-ups
quest/m1/interop-coverage/draft18-status-fin.md(quest: import the draft-18 TRACK_STATUS issues #7441).Validation

quest review(Codex, gpt-6.1-sol, medium effort, run by the maintainer's session with--rootfrom outside this checkout) againstorigin/mainat headcc1130c1dcd0a6426ec717919f2d4165fd30e043: the land fixer's base merge and its TRACK_STATUS FIN test adaptation (f721a41), which GitHub refused to let the App push because the merge touches a workflow, plus a clean merge of currentmain. Round 1, 0 findings. The land gate runs the checks; this fork's code was not run locally.4b3cd125f0is a conflict-free merge oforigin/main(59e12a5bb9) onto that reviewed head, so the review carries over. Main's changes to the touchedietffiles (a coop budget insession.rs, the clock RNG inpublisher.rs, a stitch test insubscriber.rs) add no new caller ofpoll_cancel,poll_withdrawn,until_withdrawnorresolve.quest checkpasses, run with an installedquestand--rootfrom outside the checkout.test rsonmoq-tokio::integration backend::quic_client_close_drains_finished_track("subscribe failed: Unroutable"). That test is a flake and this PR did not cause it. It runs moq-lite (moq-lite-07-wip,rs/moq-tokio/tests/integration/backend.rs:801), and this PR changes onlyietfrequest handling. quest: pin the restart a follower gets when the serving epochless route leaves #7370 touches only quest files. The land fixer reran the fullmoq-netandmoq-tokionextest (3788 passed, the test included) on the merged batch.handle_streamargument was already fixed byf721a41, so it was answered and resolved. Pullfrog's failing check is a billing outage and was ignored.(Written by Claude Opus 5.5)
