TM / CIES / TRANSFER
What this is. A live, in-browser simulation of the Valoris oracle methodology: a hidden value process is generated, observed through three sources with their real-world failure modes (Transfermarkt's editorial smoothing lag, CIES noise, transfer-fee sparsity), and reconstructed by a particle filter. Inject an event and watch the estimate snap, or anchor a transfer and watch the confidence band collapse. Confidence band is ±2σ, matching the research convention.
What it is not. Not a price feed, not real player data, not a calibrated model. Stylized: Transfermarkt is published daily here (real median cadence 144 days) and CIES appears as a continuous second source (real: one snapshot, no history). The aging drift μ(a) is the one empirical input — estimated on the 12.5k-player thesis panel. The out-of-sample test of the filter against realized fees is in progress and not yet reported. The on-chain oracle on
the terminal serves the live testnet feed.
