Validation prompt
Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.
Do not confirm this duplicate rule as an independent code change. Keep paired iOS shadow properties plus Android elevation, elevation used with zIndex, legacy-architecture fallbacks, and shadows that must support Android below API 28. Triage any genuinely single-platform shadow through react-doctor/rn-style-prefer-boxshadow with its React Native architecture and Android API guards.
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.
Make no application-code change solely for this duplicate finding. Use the newer rn-style-prefer-boxshadow diagnostic when it applies; otherwise keep the existing platform-compatible shadow implementation.
Repository-wide copy prompt
Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.
Show repository-wide prompt
Fix every confirmed react-doctor/rn-no-legacy-shadow-styles diagnostic in the current repository.
Required change:
- Make no application-code change solely for this duplicate finding. Use the newer rn-style-prefer-boxshadow diagnostic when it applies; otherwise keep the existing platform-compatible shadow implementation.
Validation before editing:
Do not confirm this duplicate rule as an independent code change. Keep paired iOS shadow properties plus Android elevation, elevation used with zIndex, legacy-architecture fallbacks, and shadows that must support Android below API 28. Triage any genuinely single-platform shadow through react-doctor/rn-style-prefer-boxshadow with its React Native architecture and Android API guards.
Constraints:
- Make the smallest change that fixes the root cause.
- Preserve behavior and interfaces unrelated to this diagnostic.
- Reuse existing project components, utilities, and conventions.
- Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations.
- Before editing, inspect the manifest, lockfile, native app configuration, React Native and Expo versions, and New Architecture status.
- Also inspect the Reanimated major, installed list-library majors, and every affected platform-specific file.
- Do not add or upgrade a native dependency, change linking, or alter Pods/Gradle setup unless explicitly authorized.
- Do not enable the New Architecture or change Expo/native configuration unless explicitly authorized.
- Preserve navigation, gesture, keyboard, safe-area, accessibility, lifecycle, and platform semantics; do not treat them as file-local import substitutions.
- Verify behavior in a release build on each affected device platform in scope. Name any unavailable platform instead of claiming it passed.
- Adapt identifiers and framework details instead of copying blindly.
- Do not disable the rule or suppress matching code.
- Confirm this rule is enabled for the project:
advisory only; superseded by react-doctor/rn-style-prefer-boxshadow.
Assessment:
- Record detector evidence, applicability facts, assumptions, missing evidence, and the rule class for this occurrence.
- Return one outcome: Confirmed failure, Rejected, Needs evidence, Unavailable, Waived with evidence, or Observation.
- A waiver records the established failure, scope, authority, evidence, and review or expiry condition. It is not a pass or false positive.
Verification:
- Run focused tests for the changed behavior.
- Run React Doctor and confirm this diagnostic no longer appears from changed code.
- Run an unfiltered scan of the affected scope before claiming no cross-category regression.
- Report the files changed and any checks you could not run.
