Next query failure injection (explicitly simulated)

Failure injection affects only your query, never an external provider.

THIS LAB'S BOUNDARIES

Synthetic English corpora, text-based PDFs and heuristic structural chunking. Source passages are highlighted beside a PDF opened at the cited page; pixel-level highlighting and OCR are not supported. Citation validation checks provenance, not factual truth. RAG and prompt-injection defenses can still fail. Uploaded files and query traces are purged after the two-hour session expires.
