Notes and record state

Record note
Grinex remains inactive rather than dead because the April 2026 announcement confirmed an operational suspension but not permanent liquidation or closure. The Garantex-successor relationship is strongly supported by U.S. Treasury findings but is retained in narrative form until HEI lineage policy explicitly resolves the predecessor relationship.
