Chat Endpoints

Two flavors are available: streaming SSE and a simple JSON response.

POST /api/chat/stream

Request (example):

{
  "message": "What are the main themes?",
  "method": "drift", // drift | local | global | basic
  "maxTokens": 256,
  "history": [{ "role": "user", "content": "..." }]
}

Events (SSE): status, step-start, step-end, drift-log, highlights, answer-chunk, answer, warning, error, done.

Notes:

• Runs graphrag query --method <mode> under the hood
• Builds a compact context from output/entities.json + output/relationships.json
• Highlights are derived from entity title matches in the answer/question

POST /api/chat

Request body is the same as above (non-streaming). Returns:

{ "answer": "...", "highlights": ["entity_id", "..."] }
