Market intelligence
Market decisions are only as sound as the information behind them.
Decisions need a history.
The problem
Collectible markets combine sparse observations, exact-print identity, stale prices, and uncertain liquidity. A current price alone cannot explain what a decision was based on.
What we built
Cavrino publishes market intelligence artifacts for collectors, buyers, traders, and casual sellers. A private User Portfolio keeps user-owned card memory separate from public market information.
The engineering
Point-in-time research separates when an observation happened from when it became available. Sealed-input reproduction asks whether the same process can produce the same artifact. Predictive evaluation asks a different question, with its own outcome evidence.
- Exact identity before aggregation
- Observation time separate from availability time
- Public intelligence separate from private portfolio state
- Reproducibility separate from predictive performance
The boundary
Replay and research are ongoing engineering work. Reproducibility is not predictive validation, and this page makes no claim of validated returns or accepted production replay.
