Research into the digitization of traditional embroidery is shifting from archiving designs toward auditable design translation. However, the prioritisation and operationalisation of cultural elements in Sanjiang Dong embroidery still lack verifiable traceability. Field imagery screened between May and October 2024 yielded 20 core vector samples used to construct a three-tier cultural memetic spectrum (material-behaviour-spiritual) comprising six factors: patterns, colours, composition, craftsmanship, environment, and symbolism. Thirty experts performed pairwise comparisons using the Saaty 1-9 scale to compute AHP weights with consistency control (CR < 0.10). The material layer ranked highest (0.521), followed by the spiritual layer (0.337), while the behavioural layer was lowest (0.142); overall consistency met the threshold (CR = 0.034). Within the material layer, patterns outweighed colour and composition; within the behavioural layer, craftsmanship outweighed environmental factors. These weights were compiled into a rule repository that classifies variables as mandatory retention, adjustable, or prohibited. Controlled generation on a Dong-embroidery-inspired silk scarf was used to examine the applicability of the rule set through dual-path inputs and audit-field logging. The study demonstrates, within a bounded case based on 20 curated core samples, that weight-gated rules can translate cultural evidence into executable and traceable design constraints for controlled digital regeneration.
