This test’s dataset is built so Harbor actually emits both:
solve.sh sleeps 10s past a 1s agent timeout → AgentTimeoutError
test.sh still writes {"reward": 0.8}
It lives under Experimentalist because that plugin already owns the required Docker Harbor parity suite

📝 WalkthroughWalkthroughThe PR updates Harbor integration for Harbor 0.20. It adds validated lazy result loading, changes cache and trial-count semantics, preserves errored attempts with rewards, updates optional dependency constraints, and adds runtime, resume, parity, and documentation coverage.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Move prerequisites before the first runnable example.
- Move
## Installbefore## Minimal plumbing; the Python Harbor example currently precedes the Python ≥ 3.12 and Harbor-extra setup. - Move
## Prerequisites, seams & caveatsbefore## Files; bothuv runcommands currently precede the Python, Docker, and Harbor requirements.
Without this order, users can invoke an unsupported workflow.

Gate the Harbor imports during test collection. harbor is optional, but test_harbor_runtime.py imports harbor_fixtures at module scope, and packages/nemo_evaluator_sdk/tests/conftest.py has no gate. Without the harbor extra, collection raises ImportError. Add pytest.importorskip("harbor") before the import or move the Harbor imports behind the builder functions.
