- Migration 099: flexoptix_internal_demand table with RLS + v_demand_by_speed view - Import script: AES-256-CBC decrypt → parse 8585 SKUs → upsert with velocity class - 279 SKUs cross-referenced to transceiver catalog; 1288 with real demand data - New /api/internal/demand/* routes (by-speed, velocity, hype-weights, forecast-input) — protected by JWT auth + localhost/LAN IP restriction middleware - Forecast engine calibrated with real Flexoptix run-rates (demand_calibrated flag) - Dashboard: real Flexoptix Sales Velocity panel replaces DEMO DATA in Warehouse tab with momentum indicators, velocity class breakdown, trend arrows - Security: data stays on private server; RLS enforces is_internal=TRUE at DB layer
