… (B1) Replaces the grocery/X5 reference generator and DV2 demo seeds with the own-brand kitchen-appliance importer legend pinned in docs/domain.md and docs/generator-spec.md: 30 suppliers (22 CN/5 RU/2 AE/1 KZ), 160 SKUs across 10 categories with a FOB<landed<wholesale<mp-net<RRC pricing ladder, and DV2 seeds recalibrated to 2,500 customers (2,000 retail + 500 dealers), 10,000 orders split by channel/branch, and dealer-only retro-bonus loyalty in msk/spb/ekb. New reference/legend.py is the single numeric source of truth; tests/unit/test_generator_spec_invariants.py encodes generator-spec.md §12's 12 consistency invariants as machine-checkable tests. Live ClickHouse/Postgres re-verify of the rewritten seed SQL is B4's job (no Docker available in this environment); this pass is scoped to the generator, seeds, and everything testable without a live warehouse.

CI's float summation of SEASONAL_B2B lands at 12.000000000000002 instead of 12.0 (non-associative float addition, platform-dependent rounding) — exact equality on a float sum was never safe to begin with. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
