Description

Moves the Protect challenge lifecycle out of the useProtectCheckRunner hook in @clerk/ui into a framework-free ProtectCheckRunner class in @clerk/shared/internal/clerk-js/protectCheckRunner. The hook now binds that runner to the card's spinner, error state, and continuation. No behavior change for the prebuilt <SignIn /> and <SignUp /> protect-check cards.

First part of supporting Protect challenges in custom flows. A follow-up has clerk-js run the same runner outside the prebuilt components.

📝 Walkthrough

Walkthrough

The change adds a shared ProtectCheckRunner to execute Protect challenges, submit proofs, and handle expired challenges and already-resolved responses. The UI hook delegates challenge processing to the runner and uses its outcomes to continue or stop processing. Tests cover runner outcomes, errors, and reload limits. The changeset file contains empty YAML frontmatter.

@wobsoriano wobsoriano changed the title refactor(ui,shared): move the protect_check challenge lifecycle into @clerk/shared refactor(ui,shared): move the protect_check challenge lifecycle into shared package Sep 25, 2026
A class with no framework dependency that runs one Protect challenge against a sign-in or sign-up resource. It executes the challenge script into a container, submits the proof token, reloads on protect_check_already_resolved, and reloads an expired challenge under a capped budget. Aborting the signal rejects with protect_check_aborted, and a proof that arrives after the abort is never submitted.
…kRunner

The hook keeps the React bindings only. The token-keyed effect, spinner and error state, the flushSync widget visibility handshake, the no-RHC fail-closed guard, and the onResolved continuation stay here. The challenge lifecycle now comes from ProtectCheckRunner in @clerk/shared, loaded lazily behind the same compile-time flag so no-RHC bundles still tree-shake the remote import.

Part 1 moves internal code with no user-facing change, so it takes an empty changeset per AGENTS.md.
…tainer clearing, and the lazy import

A cancelled run no longer reloads and routes after a protect_check_already_resolved submit. The hook empties the challenge container synchronously again, together with the visibility reset, instead of the runner doing it after an await. The runner module is imported directly behind the no-RHC guard as main imported the loader, and only when no runner exists yet.
The runner has one caller, the React hook, so the class, its instance state, reset(), and the lazily built runner ref were ceremony. runProtectCheck takes the resource accessors per call, and the hook passes paramsRef.current straight in. The expired-reload budget is back in the hook's reloadCountRef, reset on retry as on main, so it still counts across effect re-runs. The reissued outcome stays: the hook's effect is keyed on the challenge token and runs a reissued challenge itself.

188-201: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Check cancellation after the lazy import and before routing on outcome.

The effect can be cancelled while import(...) is pending. This happens when a token re-run or a retry calls cleanup. In that case, runProtectCheck still starts, but it rejects immediately because the signal is aborted. That path is safe.

A second path is not safe. Assume the stale run's submitProtectCheck resolves and the effect is cancelled after that. The same applies to the already-resolved reload. The hook then checks only isUnmounted() and calls onResolved for a superseded run. A newer run may own the card at the same time, so two continuations can route. The previous review raised this concern for the lazy-runner gap.

Add a cancelled guard after the import. The existing design intentionally keeps the post-clear continuation alive when clearing protectCheck re-runs the effect. For that reason, do not add a general cancelled check before onResolved. Instead, compare runIdRef.current with runId so that only a newer run blocks the continuation.

Proposed fix
         const { runProtectCheck } = await import('@clerk/shared/internal/clerk-js/protectCheckRunner');
+        if (cancelled) {
+          return;
+        }
         const outcome = await runProtectCheck(paramsRef.current, protectCheck, {
@@
-        if (outcome.status === 'reissued' || isUnmounted()) {
+        if (outcome.status === 'reissued' || isUnmounted() || runIdRef.current !== runId) {
           return;
         }
