Permissions Brain.
Granular row/column ACL enforcement gated by voiceprint.
What this brain does
The Permissions Brain enforces granular access control (patent 18) at the row, column, and cell level, gated per voiceprint rather than per username. When a voiceprint is revoked (employee departs, account compromise), previously authorised reads are retroactively flagged in the ledger and the actor is excluded from any future composition. This is access control built for the era of voice-attested actors.
