JEM is an open structural map (YAML → graph.json → web UI) with an optional researcher infrastructure layer (FastAPI, MCP tools, SQLite). There are no user accounts and no secrets in the public dataset.
Do not commit: jem/data/jem.db, jem/.env, API keys (ANTHROPIC_API_KEY), or ephemeral .claude/outputs/. Use jem/.env.example as a template.
- Data integrity / malicious PRs: GitHub security advisory (private report to maintainers).
- Production hosting: @dso6060 via GitHub — not handled by co-maintainer by default.
In scope: tampered YAML intended to misrepresent institutional facts, compromised GitHub Actions workflows, dependency supply-chain issues in jem/scripts/requirements.txt and jem/scripts/requirements-dev.txt, exposed API keys in commits.
Out of scope: Disagreement with structural interpretation of law (use contested-fact process instead).
