Agent Quick Fix

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

Product: Firebase Android
Current-contract area: firebase-auth 24.0.0 regression signs users out on cold start
Likely root cause: Users restored from cross-device backup are signed out every app launch.
Repair direction: Verifier checks behavior across multiple requests/build modes, not merely compilation. Check the resolved dependency graph and runtime behavior on the declared minimum platform.

Symptom

Users restored from cross-device backup are signed out every app launch.

Why This Happens

Local code often type-checks under both old and new framework semantics; the failure depends on the installed framework version and current runtime defaults.

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.
