// black box recorder
The public flight recorder for risk.
The Black Box Recorder preserves public l0g risk frames as they existed at the time. It is built to keep replay honest: no look-ahead bias, no silent backfill, no fake continuity.
Each frame records what was publicly available at a date: signals, sources, models, freshness and hashes.
A missing date stays missing. The system does not fill historical gaps to make the record look cleaner.
Integrity manifests expose SHA-256 hashes so a served artifact can be checked against the public snapshot.
The Black Box is designed for audit, monitoring and backtest hygiene, not for pretending risk can be reduced to a prophecy.
