vitron-ai/alethia

Agent-native E2E runtime with verifiable safety. 13 MCP tools including alethia_propose_tests (agent generates tests from a URL), alethia_assert_safety (proves destructive actions are blocked), and the expect block: NLP primitive unique to Alethia. Zero-IPC, ~45x faster than Playwright, signed evidence packs. Works with Claude Code, Cursor, Cline.
