This host is the landing page. The product itself, its data and its API live on
the application host.

## What the artefact is

- Rebuilt **every minute** with a fixed `as_of`, a revision and a contract
  version. Nothing is ever rewritten in place: a referenced snapshot can be
  retrieved later with the same evidence, and a new question reads the current
  market unless a specific snapshot is requested.
- **Seventeen sections** in one schema on one clock: price, price structure,
  order flow, price/flow response, derivatives, positioning, volatility,
  options, ETF, on-chain, macro events, rates, market session, peer asset,
  cross-asset, economic indicators, earnings.
- **Quality travels with every number**: observed completeness, what is still
  warming, and the count of flagged values. `null` means unavailable and never
  zero; nothing is filled in or scaled.
- Windows carry the **equal window before them**, and observations are ranked
  against thirty days of complete windows (percentile and a robust z).

## Not here

No trading signals, no advice, no positions. The product publishes market
state and the quality of it; what to do with that is the reader's decision.
