react-doctor/unused-file

A source file is unreachable from every discovered project entry point

Validation prompt

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

This opt-in project rule reports a source file that no discovered production, test, config, package, or framework entry point can reach. Confirm framework conventions, generated loaders, string-based registration, and external consumers before accepting the finding. Reject files loaded through a path or runtime mechanism that the import graph cannot resolve.

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.

Review a candidate correction

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

Reported pattern

// src/legacy-banner.tsx
export const LegacyBanner = () => <aside>Archived plan</aside>;

Candidate corrected pattern

// src/app.tsx
import { LegacyBanner } from "./legacy-banner";

export const App = () => <LegacyBanner />;

Fix prompt

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

Delete the file when it is obsolete. If the application still needs it, import or register it from the correct entry path. Preserve side effects and framework registration behavior, then run a full React Doctor scan.

Repository-wide copy prompt

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