Agent Quick Fix

Repair against the current Python 3.13 / nis contract, then keep the change narrow and source-backed.

Product: Python 3.13 / nis
Current-contract area: Removed stdlib module `nis` reached through an integration path
Likely root cause: Enterprise identity lookup path fails on import.
Repair direction: Verifier checks the maintained replacement package/API and behavior, including edge cases. Verify functional parity on representative inputs, not only a replacement import.

Symptom

Enterprise identity lookup path fails on import.

Why This Happens

The import is locally valid for older runtimes and may have no project dependency declaration; only the target runtime's current stdlib contents resolve it.

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.
