TanStack Router's `redirect()` and `notFound()` throw special errors caught by the router. Move them outside the try block or re-throw in the catch

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

Fires on throw redirect(...) or throw notFound(...) located lexically inside a try block but not inside a catch clause. The rule does NOT verify whether the surrounding catch re-throws router errors.

Suppress when: a catch that already isolates and re-throws redirect/notFound: the throw inside try is still flagged for visibility.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Move the throw outside the try, or in the catch re-throw router errors first: catch (err) { if (isRedirect(err) || err instanceof Response) throw err; ... }. Otherwise a broad catch swallows the special error TanStack Router uses internally to perform the navigation. See https://tanstack.com/router/latest/docs/framework/react/guide/navigation

Repository-wide copy prompt

Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.
