Honest about the evidence.

Run V2 locally. This public page is a read-only fixture explorer, with a real recording and downloadable evidence.

Fixture workflow: Available to inspect locally
Live discovery: V1: recorded live repair. V2: fresh search and safe abstention.
V2 page inspection: Bounded titles, headings, excerpts and hashes. Inconclusive evidence blocks approval; meaning still needs your review.
Source handling: Memory-only sessions. No runtime LLM, telemetry, or document storage.

Live mode requires an existing SerpApi key and public, non-confidential documents. It can consume existing credits, with a bounded allowance for attempted calls per process. Read the live-mode boundaries.
