Output STRICT JSON with keys: entities (list) and relations (list). Entity schema: {name,type,aliases,attributes,descriptions,evidence,mentions}. mentions is a list of {chunk_id,summary,attributes,evidence}. Relation schema: {subject,relation,object,evidence,mentions}. mentions is a list of {chunk_id,summary,evidence}. Use ontology core types when possible. Do not invent new top-level entity type labels outside the ontology if an existing type fits. Prefer normalized relation names from the ontology alias list. If an existing entity card clearly matches a mention in this chunk, reuse that card's canonical name. If the chunk uses a title, alias, or shortened reference that matches a card, keep it under the same entity instead of splitting it. Keep outputs compact: at most 8 entities and 8 relations for this pass. Each description/evidence/summary should be short (<=30 characters) and avoid full sentences. Limit each entity to <=2 descriptions and <=2 mentions; each relation to <=1 mention. For mentions in this chunk, set chunk_id to the provided CHUNK_ID. Only include information supported by the chunk. Return a single JSON object and nothing else (no markdown, no code fences). If unsure, return {\"entities\":[],\"relations\":[]}.\n\nTEXT CHUNK:\nSuddenly she came upon a little three-legged table, all made of solid\nglass; there was nothing on it except a tiny golden key, and Alice’s\nfirst thought was that it might belong to one of the doors of the hall;\n\nbut, alas! either the locks were too large, or the key was too small,\nbut at any rate it would not open any of them. However, on the second\ntime round, she came upon a low curtain she had not noticed before, and\n\nbehind it was a little door about fifteen inches high: she tried the\nlittle golden key in the lock, and to her great delight it fitted!\n\nAlice opened the door and found that it led into a small passage, not\nmuch larger than a rat-hole: she knelt down and looked along the\npassage into the loveliest garden you ever saw. How she longed to get\n\nout of that dark hall, and wander about among those beds of bright\nflowers and those cool fountains, but she could not even get her head\nthrough the doorway; “and even if my head would go through,” thought\n\npoor Alice, “it would be of very little use without my shoulders. Oh,\nhow I wish I could shut up like a telescope! I think I could, if I only\nknew how to begin.” For, you see, so many out-of-the-way things had\n\nhappened lately, that Alice had begun to think that very few things\nindeed were really impossible.\n\nThere seemed to be no use in waiting by the little door, so she went\nback to the table, half hoping she might find another key on it, or at\nany rate a book of rules for shutting people up like telescopes: this\n\ntime she found a little bottle on it, (“which certainly was not here\nbefore,” said Alice,) and round the neck of the bottle was a paper\nlabel, with the words “DRINK ME,” beautifully printed on it in large\n\nletters.\n\nIt was all very well to say “Drink me,” but the wise little Alice was\nnot going to do _that_ in a hurry. “No, I’ll look first,” she said,\n\n“and see whether it’s marked ‘_poison_’ or not”; for she had read\n\nseveral nice little histories about children who had got burnt, and\neaten up by wild beasts and other unpleasant things, all because they\n_would_ not remember the simple rules their friends had taught them:"
