Maintainer validation date: October 13, 2026. The native LangChain and real-Core E2E checks were run on hardened RC2. Its behavioral modules (bridge.py, core.py, leases.py, middleware.py) remain byte-for-byte unchanged in the GitHub-ready source. The maintainer separately reran the GitHub-ready package's unit/security suite, release-source audit, distribution build, metadata/archive checks, and fresh Windows wheel-consumer installation. No hosted CI or public PyPI installation is inferred from these local results.
| Layer | Result | Evidence and limitations |
|---|---|---|
| Windows local unit/security tests | PASS — 114/114 | Python 3.12.6; 94.81% statement coverage; python -m pytest -q --cov=loopgrid_langchain --cov-fail-under=90 |
| Native installed SDK | PASS | LangChain 1.4.5; actual create_agent synchronous/asynchronous tool handler; one sync + one async synthetic call; replay refused |
| Real LoopGrid Core E2E | PASS | Core 0.8.1-design-partner; signed workspace verify success; no failures, evidence_complete, 100% applicable coverage; two synthetic action callbacks |
| Real LangChain + real Core combined | PASS | Installed LangChain create_agent, Core 0.8.1-design-partner, decision dec_eda5d829d53640be842bb383, workspace ws_7a4ae59217aa4d1d; signed verification true, failures [], evidence_complete, 100% applicable coverage, one synthetic handler execution |
| Compile/build | PASS | Python compilation and standard python -m build wheel + source archive |
| Metadata check | PASS | python -m twine check dist\* reported PASSED for wheel and sdist |
| Archive verification | PASS | python scripts/check_dist.py contents verified |
| Dependency integrity | PASS | python -m pip check: no broken requirements |
| GitHub-ready release-source audit | PASS | python scripts/check_release_source.py: documentation, local links, package identity, exclusions, CI workflow files verified |
| Fresh Windows wheel consumer | PASS | Separate .consumer-venv on Python 3.12.6; installed built loopgrid_langchain-0.1.0-py3-none-any.whl with dependencies; imported CoreClient, LangChainBridge, create_loopgrid_middleware plus LangChain; pip check found no broken requirements |
| Linux offline local tests | PASS | Prior engineering run, Python 3.13.5; 114/114 tests, 94.81% coverage |
Scope limits: Tests used synthetic model responses and synthetic external actions. No funds were moved, no live model-provider invocation was demonstrated, and a Core service-side signed workspace verification is not a detached, independently pinned-key offline bundle verification. The separately created Windows wheel-consumer environment verified a built local wheel, not installation from the public PyPI registry. A fresh public-registry install remains a post-publication gate.
GitHub-hosted CI, GitHub Release, PyPI Trusted Publishing, public registry installation, website deployment, and external ecosystem listing are independent steps. Their current status should be read from the relevant live external service, not inferred from this dated Windows validation record. The source ships CI and OIDC workflow definitions; a workflow file is not proof that hosted CI or OIDC publication executed.
See Local validation. The native installed LangChain smoke (native_agent_e2e.py) tests a synthetic Core; the real-Core E2E (real_core_e2e.py) does not use the native agent. Run both, plus native_core_agent_e2e.py, to test all three boundaries.
