fix(auth): stop reporting an unsolved captcha as a wedged challenge - #3940
Conversation
A visitor who never completes an interactive challenge hit the same 120s deadline as a challenge that genuinely stalled, so both were reported as TURNSTILE_CHALLENGE_WEDGED. The anomaly that report exists to catch ended up drowned out by the ordinary case of nobody clicking. Cloudflare tells us which case we are in: onBeforeInteractive fires before the challenge turns interactive and onAfterInteractive when it leaves, so a deadline reached between the two is an abandoned challenge rather than a wedged one. Those are tracked as captcha_abandoned now, leaving the Sentry report for the case it was built for. The rejection is a real Error as well. As a plain object it escaped the auth mutations into the global MutationCache reporter and filed a second, untagged, error level issue for every one. The five auth mutations opt out of that with a predicate narrow enough to leave genuine auth API failures reportable, and the widget's own message now reaches the visitor in place of "An unexpected error occurred".

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.
Beyond the inline JSDoc nit, I also examined two edge cases in the abandoned/wedged split in Turnstile.tsx: whether a genuine Cloudflare stall occurring mid-interaction could be misclassified as "abandoned" instead of "wedged" (relies solely on the isAwaitingInteraction flag), and whether the abandoned branch skipping hasReportedFailure.current = true could let a later widget onTimeout/onError callback still report the same run to Sentry. Both are real edge cases inherent to the design tradeoff described in the PR rather than clear regressions, so I'm not blocking on them, but a human look is still worthwhile given the timing-dependent nature of this logic.
Extended reasoning...
This run confirmed one inline nit (a multi-line JSDoc block violating the repo's one-line JSDoc convention) and separately investigated two behavioral edge cases in Turnstile.tsx's new abandoned/wedged classification: (1) misclassification risk if a genuine Cloudflare-side stall happens to occur after the widget turns interactive, and (2) the abandoned branch not setting hasReportedFailure.current, unlike the sibling WEDGED branch, which could theoretically allow a later onTimeout/onError widget callback to still report to Sentry within the same run. Both are timing/state-dependent scenarios that are plausible but not clearly demonstrated as reachable in practice given the stated deadline and retry semantics, so they were not escalated to confirmed findings. Given this residual uncertainty around timing-sensitive auth/error-reporting logic, a brief human look is worthwhile in addition to the automated review.
…passes The overlay is full-bleed at z-101 over an opaque background and stays up for as long as the status says the challenge is interactive. Nothing reset that status when the deadline elapsed, so a visitor who let an interactive challenge lapse kept looking at the captcha while the error explaining it rendered underneath, out of sight. The deadline now moves the widget to a non-visible status before it rejects, on both the abandoned and the wedged path.

Looks good — the earlier JSDoc nit (SKIP_REPORTING_CAPTCHA_OUTCOME) has been collapsed to one line, and the follow-up commit fixing the overlay staying visible past the deadline is a small, well-targeted change with dedicated test coverage (including a test asserting pointerEvents flips to none once status becomes "timedout").
What was reviewed: the isAwaitingInteraction tracking and onAfterInteractive wiring, the new CaptchaChallengeError type and its Sentry-skip predicate, the describeError extraction in RemoteApiError, and the five auth mutation call sites gaining SKIP_REPORTING_CAPTCHA_OUTCOME. No CODEOWNERS restriction applies to these paths, and the new/updated specs already follow the repo's setup()/mock<T>() conventions.
Extended reasoning...
Overview
This run reviews the state of the PR after a new commit (68ca03f) that (a) addresses my prior inline nit — the JSDoc on SKIP_REPORTING_CAPTCHA_OUTCOME is now a single line — and (b) fixes a genuine follow-on bug: the captcha overlay stayed visible after the challenge deadline because nothing reset status out of the VISIBILITY_STATUSES set. The fix adds a "timedout" status set before both the abandoned and wedged rejection paths, with a new test asserting the overlay's pointerEvents becomes "none" after the deadline.
Security risks
None identified. The change only affects client-side captcha UX and error-reporting classification (Sentry tagging via meta); no auth logic, token handling, or permission checks are altered. CaptchaChallengeError carries only a reason/code enum and a static message map, no user input is reflected unsanitized.
Level of scrutiny
The diff is compact, self-contained, and every behavioral change (abandonment detection, overlay teardown, typed rejection) has a corresponding unit test, with the author noting mutation-testing was performed. My previously raised nit was promptly and correctly fixed. Combined with no outstanding CHANGES_REQUESTED review and no CODEOWNERS entry restricting these paths, this is now approvable.
Other factors
The bug-hunting system's own investigation into whether the overlay teardown is fully robust against Cloudflare's auto-retry (onError re-showing the overlay) was already ruled out as not a new issue introduced by this diff. Test coverage in Turnstile.spec.tsx, CaptchaChallengeError.spec.ts, and RemoteApiError.spec.tsx all follow the repo's setup()-at-bottom and mock<T>() conventions.
The abandoned path returned without marking the run settled, so the widget was left live in an interactive challenge that Cloudflare times out on its own schedule, well after our deadline. That late callback found the run still eligible to report and filed it as TURNSTILE_CHALLENGE_TIMED_OUT, which moved the noise to a different tag instead of removing it. Both deadline paths now settle the run. The flag is named for that job rather than for reporting, since deciding a challenge was merely abandoned ends the run just as firmly as reporting an anomaly does.

Chased the two edge cases from the last review instead of leaving them for a human read. One was real.
This is reachable, not theoretical. After our 120s deadline abandons a run, the widget is left live in an interactive challenge, and Cloudflare times that out on its own schedule afterwards. The late Both deadline paths now settle the run, and the flag is renamed A Cloudflare stall mid-interaction being misclassified as abandoned. Not changing this.

Why
TURNSTILE_CHALLENGE_WEDGEDfires whenever a login captcha fails to settle inside the 120s deadline, but it could not tell two very different situations apart:api.jsrace in fix(auth): start the turnstile challenge once cloudflare's script lands #3890 was found.onTimeoutnever gets a chance to fire.The second case is ordinary and much more common, so the report had stopped being a useful signal.
Both cases also reached Sentry twice. The challenge rejected with a plain object, which escaped the auth mutations into the global
MutationCachereporter and filed a second, untagged, error-level issue grouped as "Object captured as exception with keys: reason".Separately, a visitor whose challenge did not settle was told "An unexpected error occurred. Please try again or contact support if the issue persists", which points nowhere near the captcha they were looking at.
What
Turnstilenow tracks whether Cloudflare is waiting on the visitor, viaonBeforeInteractiveandonAfterInteractive(the latter was not previously wired). A deadline reached inside that window is an abandoned challenge: it is tracked ascaptcha_abandonedin Amplitude and not reported to Sentry. Outside it, theWEDGEDreport is unchanged.CaptchaChallengeErrorrather than a plain object, so they group properly in Sentry and carry a message meant for the visitor.SKIP_REPORTING_CAPTCHA_OUTCOME. It is deliberately narrower than the existingSKIP_REPORTING_HANDLED_BY_CALLER, so genuine auth API failures from those same mutations are still reported.RemoteApiErrorrenders the captcha message when the failure is a captcha outcome.TURNSTILE_CHALLENGE_FAILEDandTURNSTILE_CHALLENGE_TIMED_OUTare untouched.No visual change. The only user-visible difference is the alert text when a captcha does not complete.
