- Treatments book their dose from a medicine lot (delta booking on edit, bulk all-or-nothing, idempotent); Bestandsbuch columns from the lot, FEHLT exactly where treatmentLogGaps reports a gap; Bestandsbuch export needs veterinary-medicines:read. - Label printing: 409 LABEL_PARTICULARS_MISSING on gaps, proof print with watermark, PRINT audit before the PDF, check endpoints; digit rules only from the seeded ComplianceSettings row (fail closed). - Restricted zone (Berlin day): create, update, move, merge and CSV import blocked inside an active restriction; override with reason and compliance:manage, audited, never stored on the colony; split, harvest and dissolve stay free; restriction details only with compliance:read. - Authority notices: settings, herd snapshot, registration/herd change/TSK notices with one open draft per kind under the settings lock. - Label check refinements (geometric reading order, number|unit pairs). - ARCHITECTURE.md §12.6–12.8, Annahmen 71–77; spec §5.6 Berlin day.
