The expected verdict is on the card before you run it. These are recorded runs, so nothing is being hidden from you — and watching a check fail is the only proof it measures anything. PASS level 3 · JSONL bridge ### Tidies the folder Classifies and indexes the document store without changing it.

Tidying by removal. The documents are gone and the index looks tidy. examples/subjects/ deletes_documents.py ### Connect your own Beacon grades an agent over MCP, A2A, or a JSONL bridge of about thirty lines. That runs on your machine, not in this browser — the playground only replays what was recorded. python3 -m beacon run --adapter a2a --agent-url … Project Beacon Beacon grades observable outcomes and state changes. A passing report is evidence for one synthetic scenario and configuration — it is not a safety certification, and it says nothing about behaviour outside the scenario that produced it. © 2026 Marshall Cahill and Project Beacon contributors · Apache 2.0 · every scenario fixture is synthetic · 83 scenarios [Licensing and privacy](/legal) [github.com/RealMaxPower/project-beacon](https://github.com/RealMaxPower/project-beacon) ## Other pages - [All pages](https://beaconlab.dev/index.md)
