Implemented fuzz test fix in apexchainx_calculator/src/fuzz_tests.rs and ensured the test suite passes.

Completed the fix and verified tests pass.

Updated:

  • apexchainx_calculator/src/fuzz_tests.rs: test_fuzz_compute_result_overflow_rejects_silently_clamping now allows the overflow path to return either SLAError::InvalidPenaltyAmount or SLAError::InvalidRewardAmount (overflow can be detected at different arithmetic sites).
  • Verified with cargo test -p apexchainx_calculator resulting in 425 passed; 0 failed.

Closes #68

Thanks for hardening compute_result — exactly the kind of pragmatic work we want! Currently the Checks tab shows no completed runs for the four CI jobs that gate contracts here: client-checks, e2e-tests, fuzz-tests, provenance-hashes.

That almost always means the per-PR workflow has not fired yet. Pushing a rebase (or an empty commit) onto latest main reliably re-triggers it; for first-time contributors the Checks tab sometimes needs a maintainer to click "Approve and run". Once all four are green I will merge immediately. 🚀
