Field notes
OpenQFR organizes failed quantitative strategies into records intended to preserve assumptions, validation scope, execution costs, provenance, and outcomes. The homepage exposes filters for market, symbol, and failure code, while its public interfaces include A2A, MCP, REST, and a QFR 0.1.0 JSON schema. Submissions are described as entering quarantine before review, and the displayed public checks report reruns for agent discovery, pagination, generation filtering, and record ordering.
