Review analysis and recommendations for PR #1636 Request Caching

[Copilot]

Analysis of review comments from CodeRabbit, Copilot, Graphite, and @anttimaki on the request caching implementation. No code changes made—this documents recommended actions pending approval.

Recommended Changes

High Priority

• Remove vague TODO (entry.client.tsx:23) — Sentry.init is synchronous, comment serves no purpose
• Fix restrictedNames check (requestCache.ts:47) — validate func.name not user-provided funcName
• Style fixes — add missing blank line, use object shorthand { funcName, inputs, promise }

Medium Priority

• Rename for clarity:
  • getRequestScopedDapper → getClientLoaderDapper
  • getCachedRequestPromise → deduplicatePromiseForRequest
• Add docstrings explaining deduplication purpose and usage
• Simplify initializeClientDapper if factory pattern complexity is test-only

Low Priority

• Add test cases: promise rejection, reference equality, different args
• Verify Remix revalidation doesn't serve stale cache

Declined Suggestions

• O(1) Map lookup — linear search fine for typical cache size
• Custom equality function — lodash isEqual sufficient
• Input size warnings — overengineered

Awaiting approval before implementation.
