fix(clerk-js,react,shared,ui): bound loading a verification, not running one - #9527
Conversation
The SDK raced the whole verification against a fixed 60s wall: loading the module, running it, and the round-trip that follows. That is a duration the SDK is not in a position to judge. Which verification runs is decided by the backend per request, long after the bundle shipped, and what it does varies from waiting on a person to transferring data over an unknown connection, so no single number is right for all of them. When the wall tripped, a verification that was progressing normally was aborted and reported to the user as a timeout, and because retrying restarts the work from the beginning, any connection slow enough to trip it once would trip it again. The bound now covers only loading the module, and stops there: once the module takes control it governs its own duration and the SDK imposes no limit. The default is 60s, deliberately generous, because nothing legitimate waits on this timer — its only job is a connection that is accepted and then never answered, since every other load failure already rejects on its own, a blocking Content-Security-Policy included. challenge_load_timeout_ms overrides that default, on a loader or on the instance, resolved loader first. Per loader because loaders roll out gradually: while a new one ramps two are live for the same instance at once, and the new one may need a different value from the one it replaces. Which loader a browser was assigned is a random draw per page load and cannot be recomputed from the config, so Protect reports what the applied loader asked for. Absent means "inherit" at both levels, so the default stays one number under our control rather than being frozen into stored settings.

…edence Three defects a second-model review found in the load bound. An abort landing while the import was stalled settled nothing: the signal was not part of the race, so an unmounted component kept the promise, its closures and its timer alive for the whole bound and then reported a load failure for what was a cancellation. The signal is raced now and rejects as protect_check_aborted, matching the contract every other path already honours. setTimeout stores its delay in a signed 32-bit int, so a configured value above 2^31-1 overflowed and fired immediately — failing every load instantly, which is the exact opposite of what an operator asking for a long timeout wanted. The value is clamped, and non-finite values fall back to the default rather than being passed to the timer. The precedence doc and the code disagreed. The doc said an absent loader value inherits the instance-wide one, while the code takes the first APPLIED loader that specifies one — so a value set on one of two live loaders would apply to browsers that got the other. The code is the sensible rule, since there is no single "the" loader once more than one is live, so the doc now states it and warns that an instance running two loaders should set this on both or neither.

📝 WalkthroughWalkthroughThe change adds optional Protect challenge module-load timeout configuration. Valid loader values propagate through Protect and Clerk to the UI runner. Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR adds configurable verification-module loading timeouts, but the instance-level setting is currently ignored when no loader override is present, so affected applications may not receive the timeout they configured.

Looks good to me! Left a few comments but nothing blocking.

Hmm, I think maybe isomorphicClerk needs the new __internal_protectChallengeLoadTimeoutMs too, or else it will likely fail to read and fall back to the default?
Update: Actually, maybe not. This is just used from UI so should read directly from clerk and not the isomorphic one. If we move SignIn/SignUp to be rendered inside the host app, like we are working on for the UserButton, that might change though and since this fails silently it would be hard to catch. So not necessary, but might still be a good idea. 😄

Description
Before this change, the UI raced both verification-module loading and challenge execution against one fixed 60-second host timeout. A valid long-running challenge could therefore be aborted and reported as timed out; retrying restarted the same work from the beginning.
This PR limits the SDK-owned deadline to the dynamic module load. Loading remains bounded and abort-aware, with a 60-second default and a 600-second ceiling that prevents oversized timer values from overflowing. Once the module has loaded, the challenge owns its execution duration and the host imposes no hard deadline.
The optional
challenge_load_timeout_msenvironment field can override the load bound for an instance or an individual loader. Among the loaders applied to the current browser, the first finite, positive loader value wins; the instance value is used when no applied loader supplies one, and the SDK default is used when neither does. The selected loader value is exposed by clerk-js and forwarded throughIsomorphicClerk, allowing@clerk/uito read it across the CDN/package boundary while safely falling back when paired with an older clerk-js version that does not provide the getter.An invisible challenge that never settles can now leave the host spinner visible indefinitely; once a challenge exposes a widget, that widget owns the progress UI. Challenge-aware soft status and recovery UX are tracked internally. When the optional backend configuration is absent, existing instances use the SDK default.
