Progressive reading

Read in layers, not all at once

An agent deciding whether a document is worth reading shouldn’t pay for the whole document. Each layer is a separate call, cheap enough to run across the full candidate set. Real numbers.

Filters that match how lawyers search

Coverage & bias notice

Coverage & bias notice

Chinese criminal judgments are fully indexed. Civil judgments are ~12% indexed and the sample is not random — it follows the enrichment queue. Every Law response carries a coverage block that says so; put it in your tool description so the agent qualifies civil-case claims. Until enrichment completes, treat civil retrieval as indicative, not exhaustive.
