Update 9 validation passes to record errors directly on fn.env instead of
returning Result<void, CompilerError>:

  • validateHooksUsage
  • validateNoCapitalizedCalls (also changed throwInvalidReact to recordError)
  • validateUseMemo
  • dropManualMemoization
  • validateNoRefAccessInRender
  • validateNoSetStateInRender
  • validateNoImpureFunctionsInRender
  • validateNoFreezingKnownMutableFunctions
  • validateExhaustiveDependencies

Each pass now calls fn.env.recordErrors() instead of returning errors.asResult().
Pipeline.ts call sites updated to remove tryRecord() wrappers and .unwrap().

Add detailed plan for making the React Compiler fault-tolerant by
accumulating errors across all passes instead of stopping at the first
error. This enables reporting multiple compilation errors at once.

…ent (#35873)

Add error accumulation methods to the Environment class:
- #errors field to accumulate CompilerErrors across passes
- recordError() to record a single diagnostic (throws if Invariant)
- recordErrors() to record all diagnostics from a CompilerError
- hasErrors() to check if any errors have been recorded
- aggregateErrors() to retrieve the accumulated CompilerError
- tryRecord() to wrap callbacks and catch CompilerErrors

…erance (#35874)

- Change runWithEnvironment/run/compileFn to return
Result<CodegenFunction, CompilerError>
- Wrap all pipeline passes in env.tryRecord() to catch and record
CompilerErrors
- Record inference pass errors via env.recordErrors() instead of
throwing
- Handle codegen Result explicitly, returning Err on failure
- Add final error check: return Err(env.aggregateErrors()) if any errors
accumulated
- Update tryCompileFunction and retryCompileFunction in Program.ts to
handle Result
- Keep lint-only passes using env.logErrors() (non-blocking)
- Update 52 test fixture expectations that now report additional errors

This is the core integration that enables fault tolerance: errors are
caught,
recorded, and the pipeline continues to discover more errors.
