Summary

• add ExternalSimulationAdapter protocol for third-party/heavyweight simulation integrations
• add validate_external_adapter_result() to fail loud on batch length, module, version, and uncertainty mismatches
• export the contract from openamp_foundry.simulation and document consent/network/model-download requirements

Honest scope

• no external simulator, model download, network execution, MD, or AlphaFold integration added
• contract only prevents hidden behavior and output-shape drift; it does not validate biological usefulness

Verification

• python3 -m pytest -q tests/test_simulation_interfaces.py tests/test_public_api_imports.py tests/test_docs_consistent.py
• ruff check src/openamp_foundry/simulation/interfaces.py src/openamp_foundry/simulation/init.py tests/test_simulation_interfaces.py
• git diff --check
• python3 -m pytest -q (1952 passed, 7 skipped)
• pre-push pytest -q (1952 passed, 7 skipped)

Superseded by upstream main PR #155 (). Closing to avoid duplicating the same contract on a stale head.
