Agent Quick Fix

Repair against the current Firebase C++ contract, then keep the change narrow and source-backed.

Product: Firebase C++
Current-contract area: Firebase C++ User::UpdateEmail removed
Likely root cause: Source fails to compile on the deprecated auth method.
Repair direction: Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. Check the supported successor flow and user-visible result.

Symptom

Source fails to compile on the deprecated auth method.

Why This Happens

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Common Wrong Fixes

Changing local code without checking the current external contract.
Retrying the same install, build, or API call with no version/source change.
Applying a broad unsafe bypass when a narrow compatibility fix is available.
