feat(auth)!: a credential is a handle that routes and claims name, in every binding - #8516
Score: 10/10, The incremental documentation changes correctly clarify offline credential presentation and session-wide AUTH grants, with no actionable defects found by source inspection; builds and tests were not run as instructed.
Findings: none
Problem
The C ABI could set the connection credential (moq_client_config.tokens) but had no way to put a request token on an announcement. moq-net already models it: auth::Handle::add mints a Credential, a route or claim names it with set_auth, and the publisher sends it as the moq-transport AUTHORIZATION TOKEN on PUBLISH_NAMESPACE; swapping it renews the request in place. moq-ffi and its wrappers had none of it.
The first cut exposed it in C as moq_session_credential(session, token, token_len, on_credential, user_data), a callback that fired with the handle once the peer answered. A callback parameter cannot be cancelled, and it existed only because Rust's add was async: the Credential did not exist until the peer answered.
Approach
moq-net and js/net:Handle::add (JS Handle.add) presents the token and returns the Credential at once. Credential::answered() (JS credential.answered) waits for the first verdict. Dropping (JS close()) a credential before its answer withdraws it, as dropping the add future did before.
moq-c:moq_session_credential(session, token, token_len) returns a credential handle. moq_credential_answered(credential, on_answer, user_data) reports the verdict once. moq_credential_free cancels a pending presentation (withdrawn unless a route or claim names it) and ends its waits with MOQ_ERROR_MOQ. moq_route_set_auth and moq_claim_set_auth are unchanged from the first cut.
moq-ffi:MoqSession::credential(token) returns a MoqCredential with answered() and cancel(), and MoqRoute::set_auth and MoqClaim::set_auth take an optional credential. Python, Go, Kotlin, Dart, and Swift wrap them the way each wraps tokens() and set_cost. The C and C++ packages are generated from moq-ffi, so they get it with no code change.
moq-net origin fix (from the contributor):RouteState::change, behind set_cost and set_auth, applied the update before checking liveness, so a call on a closed route returned Closed but kept the new value. It now restores the old options on any failure, through one rollback path that a_closed_route_keeps_no_refused_change covers. A failure after the liveness check is only a close racing the call.
Tests:
moq-c, against moq-tokio listeners:
moq-transport 18 and 22: route ride and renew, claim ride and withdraw.
moq-lite 07: AUTH acceptance, refusal with the peer's code, and the verdict repeated for an answered credential.
moq-lite 06: answered is MOQ_ERROR_UNSUPPORTED.
Reconnect: a credential is presented again on the next session, and freeing it withdraws it there.
Cancellation: freeing while offline (the peer never sees the token), and freeing while the peer holds it unanswered (the server sees it withdrawn).
A pending wait ends with its session, and an empty token or unknown handle is refused.
moq-ffi: the same on lite-07, lite-06, and moq-transport-18, plus set_auth with a cancelled credential.
Each wrapper: one lifecycle test.
js/net: closing before the answer rejects answered and withdraws the token, both offline and while the server holds it.
Impact
Breaking, moq-net:auth::Handle::add is synchronous and returns Result<Credential>; Credential::answered() / poll_answered() are new. Migrate let c = handle.add(t).await?; to let c = handle.add(t)?; c.answered().await?;. add now fails only on the handle's end or GoingAway; Unsupported and refusals come from answered.
Breaking, js/net (@moq/net):Handle.add returns Credential instead of Promise<Credential>, and Credential gains answered: PromiseLike<void>. Migrate const c = await handle.add(t) to const c = handle.add(t); await c.answered;. add throws synchronously once the handle ended or while its own session drains with no successor.
moq-c (additive vs. the last release):moq_session_credential, moq_credential_answered, moq_credential_free, moq_route_set_auth, moq_claim_set_auth.
moq-ffi and wrappers (additive):MoqSession.credential, MoqCredential (answered, cancel), MoqRoute.set_auth, MoqClaim.set_auth; Python Session.credential/Credential, Go Session.Credential/Credential, Kotlin and Dart credential, Swift Session.credential(_:)/Credential, and set_auth / SetAuth / setAuth on routes and claims.
Behavior: a refused set_cost/set_auth on a closed route no longer keeps the refused value.
Wire: none.
Decisions
✅ moq-c credential is an owned handle mirroring Rust's Credential (rejected: a cancellable operation handle around the callback; keeping the callback). Settled by the maintainer.
✅ Parity across moq-ffi and every wrapper in this PR (rejected: waive and track). Settled by the maintainer.
✅ Make the Rust shape a handle by making Handle::add synchronous plus Credential::answered(), mirrored in js/net (rejected: keep async add and add a second public present; two ways to present a token). Chosen while iterating; breaking.
✅ moq-ffi takes the token as a String, like MoqTokens.set (rejected: bytes, as Rust and C take). Chosen while iterating.
✅ A freed credential ends its moq_credential_answered waits with MOQ_ERROR_MOQ, as other moq-c waits do on cancel (rejected: a new error code). Chosen while iterating.
✅ Credentials are named with set_auth only; route options at creation gain no auth field in C or moq-ffi (rejected: an options field, a second way to do it). Chosen while iterating.
Alternatives
A request_token on moq_client_config plus a session-level setter would apply one token to every announcement, and has no counterpart in moq-net or moq-ffi.
The answered wait in moq-c could have held its own clone of the credential, but then freeing the handle would not cancel the presentation. The wait holds a clone only until a freed signal ends it.
Follow-ups
Swift was not compiled here (no toolchain on this Linux host). It follows the existing Tokens and setCost patterns, and the macOS platform gate checks it nightly and on release PRs.
Tokens on SUBSCRIBE remain out of scope: the moq-net client does not send one today.

moq_session_credential mints a credential from a session's auth handle,
and moq_route_set_auth / moq_claim_set_auth name it on the announcing
request: moq-transport's AUTHORIZATION TOKEN on PUBLISH_NAMESPACE.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The PR adds session credentials, verdict waiting, and cancellation. Callers can assign credentials to routes and claims, replace an assigned credential, or clear it to use session scope. The network API now returns credentials before the peer verdict is available. Language bindings, documentation, tests, and benchmarks reflect this flow. Route option changes are rolled back when an update fails.
Merge Risk: Low · previous review 46384
The credential documentation has two small gaps. It should say that a moq-lite per-request credential widens the whole session's grant, and that the C API waits for the next session when none is live. Neither changes runtime behavior, so the change is mergeable with a quick documentation follow-up.

Explanation
The title "feat(auth)!: a credential is a handle that routes and claims name, in every binding" matches the main change. The PR turns credential presentation into an owned handle (Handle::add returns a Credential immediately, answered() waits for the verdict) and adds set_auth on routes and claims across the C, FFI, and language bindings. The title is specific and conventional-commit formatted, though it is somewhat long at 83 characters.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Make pending credential creation cancellable.
If a dialed session stays offline or a peer does not answer, handle.add(token).await can wait indefinitely. This task has no retained cancellation handle, and moq_session_credential returns only zero. A caller that abandons the request must keep user_data valid or close the entire session. Return a cancellable operation handle and deliver a terminal callback on cancellation. (raw.githubusercontent.com)
As per coding guidelines, “Libraries use kio, not tokio::spawn.”

The four new functions are additive and the three tests pass locally (cargo test -p moq-c --lib credential). rustfmt --check and sh/text.sh are clean.
Two optional doc notes:
The moq_route_set_auth and moq_claim_set_auth docs say "Only the session that minted it carries it". RouteInfo::auth in rs/moq-net/src/model/origin.rs is more precise: a session built on the handle that issued it. A Client::with_auth handle carries the credential on every session it backs, so the wording could be tightened to avoid implying a reconnect loses it.
moq_route_set_auth's "Fails once its broadcast closed" mirrors Route::set_auth, which also fails when the origin's driver is dropped. The moq_claim_set_auth doc omits the failure case entirely.
RouteState::change checked liveness after applying the update, so a
set_auth on a closed route kept the credential while returning Closed.
Check first, and restore the old options if the update fails.
Clarify the moq-c credential docs: who carries a route's or claim's
credential, when setting one fails, and that moq-lite needs AUTH.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Re the unverified rs/moq-c/src/auth.rs finding (cancellable pending credential): on_credential fires exactly once, when a peer answers on the next live session, at once on moq-transport, or with a negative code when the session closes; 697639e adds a_pending_credential_ends_with_its_session to pin that close path. So a caller abandoning a pending credential can close the session, and user_data follows the same lifetime rule as moq-c's other async callbacks (valid until the terminal callback). A separate cancellable operation handle would be an API addition; happy to do it as a follow-up if you want that shape. The task uses tokio::spawn like the crate's other callback tasks (session, origin, publish), so I left it as is. (AI-assisted)
Link to the credential reference instead of duplicating its protocol details.
Keep the user workflow here: create a credential, attach it to an announcement, and replace it without redialing. Replace the added wire-field and error-code details with a direct link to the moq_session_credential API documentation. Keep the AUTH availability condition beside the workflow.

Reviewed changes
This run re-reviewed 697639e, which answers both doc notes from the previous review and adds the moq-net fix the new C docs depend on.
Tightened the moq_route_set_auth and moq_claim_set_auth docs: the credential rides only the session it was minted on (a dialed one across reconnects), and a failure keeps the route's or claim's credential as it was.
Corrected the moq_session_credential and Tokens docs: moq-transport always carries the token on the announcing request, moq-lite needs AUTH, and closing the session answers a credential still waiting.
Made RouteState::change in rs/moq-net/src/model/origin.rs check the announcement's liveness before mutating control.options, and restore the old options when the re-advertisement fails, so a closed route or claim keeps nothing it was refused.
Added a_closed_route_keeps_no_refused_change and a_pending_credential_ends_with_its_session; the hidden-route path that must still keep the change is already covered by a_hidden_route_announces_its_own_path.
Verified locally: cargo test -p moq-net --lib --features async a_closed_route_keeps_no_refused_change, cargo test -p moq-c --lib (the four credential tests), rustfmt --edition 2024 --check, and sh/text.sh all pass.
ℹ️ PR description still says moq-net is untouched
The "Public API and wire impact" section claims "No wire change and no moq-net, moq-tokio, or moq-ffi change", but 697639e changes RouteState::change, so Route::set_cost/set_auth and Claim::set_cost/set_auth now leave the options untouched when they fail. Anyone reading the description to judge scope would miss it.
Technical details
# Stale PR description## Affected sites- PR body, "What" and "Public API and wire impact" sections — list only the four ABI

Reviewed changes
This run re-reviewed 4ffa12a, a docs-only commit since the prior pullfrog review on 697639e. It settles CodeRabbit's nit on the Tokens section without changing any behavior.
Kept the per-request credential workflow in the Tokens bullet (mint with moq_session_credential(), attach with moq_route_set_auth()/moq_claim_set_auth(), renew in place) and replaced the duplicated AUTHORIZATION TOKEN and MOQ_ERROR_UNSUPPORTED detail with a link to the function's documentation, preserving the moq-transport versus moq-lite AUTH condition.
sh/text.sh passes. No new issues; the earlier doc and RouteState::change findings remain addressed.

gains MoqSession::credential, MoqCredential, and route/claim set_auth.

feat(moq-c): routes and claims carry a request credential
feat(auth)!: a credential is a handle that routes and claims name, in every binding
Nov 12, 2026
Thanks for this, @ksletmoe-aws. I pushed three commits on top of yours; your commits are unchanged.
What changed and why:
The C credential is now an owned handle.moq_session_credential(session, token, token_len) returns the handle right away. moq_credential_answered() reports the peer's verdict, and moq_credential_free() cancels a pending presentation. The callback version could not be cancelled, and it only existed because Rust's Handle::add was async.
That needed a Rust change, so Rust and JS now share the shape.auth::Handle::add (and js/net Handle.add) returns the Credential at once, and Credential::answered() waits for the verdict. This is breaking, so the title now has !, and the Impact section has the migration.
Parity. moq-ffi gains MoqSession.credential, MoqCredential (answered, cancel), and set_auth on routes and claims. Python, Go, Kotlin, Dart, and Swift wrap them, each with a test.
Your origin.rs fix now restores the options through one rollback path, so your a_closed_route_keeps_no_refused_change test covers it.
More C tests: moq-lite 07 AUTH acceptance and refusal, moq-lite 06 unsupported, persistence across a reconnect, and cancellation both while offline and while the peer holds the token.
just check and just test interop --all pass locally. Swift is the one exception: it was not compiled here. The PR body lists the decisions.

Do not describe immediate success as peer acceptance.
On moq-transport, moq_credential_answered() succeeds immediately because the credential travels on requests. That success is not a peer verdict. Callers could otherwise treat it as confirmation that the peer accepted the token. Describe it as immediate success without a verdict.

moq_session_credential(session, token, token_len, on_credential, user_data), a callback that fired with the handle once the peer answered. A callback parameter cannot be cancelled, and it existed only because Rust'saddwas async: theCredentialdid not exist until the peer answered.Approach
Handle::add(JSHandle.add) presents the token and returns theCredentialat once.Credential::answered()(JScredential.answered) waits for the first verdict. Dropping (JSclose()) a credential before its answer withdraws it, as dropping theaddfuture did before.moq_session_credential(session, token, token_len)returns a credential handle.moq_credential_answered(credential, on_answer, user_data)reports the verdict once.moq_credential_freecancels a pending presentation (withdrawn unless a route or claim names it) and ends its waits withMOQ_ERROR_MOQ.moq_route_set_authandmoq_claim_set_authare unchanged from the first cut.MoqSession::credential(token)returns aMoqCredentialwithanswered()andcancel(), andMoqRoute::set_authandMoqClaim::set_authtake an optional credential. Python, Go, Kotlin, Dart, and Swift wrap them the way each wrapstokens()andset_cost. The C and C++ packages are generated from moq-ffi, so they get it with no code change.RouteState::change, behindset_costandset_auth, applied the update before checking liveness, so a call on a closed route returnedClosedbut kept the new value. It now restores the old options on any failure, through one rollback path thata_closed_route_keeps_no_refused_changecovers. A failure after the liveness check is only a close racing the call.MOQ_ERROR_UNSUPPORTED.set_authwith a cancelled credential.answeredand withdraws the token, both offline and while the server holds it.Impact
