grounding: widened deterministic tier (H12) + US reference builder

↗ view on GitHub · Eli Ziff · 2026-07-30 · 43b68009

attestedCharacterizationReceipt: citator-provider evidence whose span
is another court's classified prose about the cited case - claims
clear the verbatim tier only by quoting the citing court's own words,
with attribution recorded in the receipt (never parsed from prose).
Tests: verbatim clears; one-word citance mutation fails; splice across
characterization+passage evidence fails. Plus build_us_reference.py
(stratified CAP static sample) and --jsonl/--suffix on the alienness
index builder for the jurisdiction-matched US index.
