What the assistant can and cannot do

What it does — deterministically

• ✓Explains an entity from its real description, relations, and cited sources.
• ✓Compares two entities by their real shared connections.
• ✓Traces the shortest evidence path between two entities, link by link.
• ✓Builds a learning path from real relations and curated paths.
• ✓Summarises the real, source-backed citations behind an entity.
• ✓Says “not enough graph evidence” when the graph cannot answer.

What it will not do

• ✗Generate prose or opinions — no language model is configured.
• ✗Assert a fact that is not already in the knowledge graph.
• ✗Invent numbers, dates, names, or citations to fill a gap.
• ✗Persist a conversation — there is no chat history or account.

The guardrails — ready for a model

If a language-model provider is ever wired in, it may only phrase the grounded facts it is given, under these rules:

1. 1.Use ONLY the facts in the provided grounded context; never introduce a fact that is not there.
2. 2.Cite the evidence for every claim, by the [F#] fact or [C#] citation it comes from.
3. 3.If the context does not contain enough to answer, reply 'Not enough graph evidence to answer.' — do not guess.
4. 4.Do not speculate, extrapolate, or add numbers, dates, or names beyond the context.
5. 5.Preserve uncertainty: if the graph marks something debated or unconfirmed, keep that qualification.

The citation-forced packet

This is exactly what a model would receive for an example entity — grounded facts and citations, and nothing else. The retrieval is real today; the generation is future work.

You are a grounded scientific assistant. Answer using ONLY the grounded context below.
Rules:
- Use ONLY the facts in the provided grounded context; never introduce a fact that is not there.
- Cite the evidence for every claim, by the [F#] fact or [C#] citation it comes from.
- If the context does not contain enough to answer, reply 'Not enough graph evidence to answer.' — do not guess.
- Do not speculate, extrapolate, or add numbers, dates, or names beyond the context.
- Preserve uncertainty: if the graph marks something debated or unconfirmed, keep that qualification.

QUESTION: What is Mars, and how does it connect to the rest of the graph?
