task: |
You are running inside an scsh container for the built-in `add` self-test.
1. Read the integers `A` and `B` from the environment.
2. Compute `S = A + B`.
3. Write the JSON object {"ok": true, "a": A, "b": B, "sum": S} to the file
named by the `SCSH_RESULT` environment variable.
4. Re-read that file and assert that `sum == A + B`. If it does not match, fail.
Do nothing else — no commits, no network, no other files.
