Live GEO data sources

Three engines now run against real AI-search backends — OpenAI web search, Perplexity Sonar and Gemini grounding — with per-run live/sampled labeling.

GEO runs can now hit real AI-search backends:

ChatGPT via OpenAI web search,
Perplexity via the direct Sonar API,
Google AI Overview via Gemini grounding.

The live label is earned per run: the key must be configured and the call must return actual search evidence — a grounded call without evidence is demoted to sampled automatically. Every run in the run list carries the label; the aggregate metrics (summary, SOV, trends, per-engine rollups) blend live and sampled, and the measurement docs say so.

All other engines keep their honest sampled labeling (LLM estimates, tracked over time).
