-- 迁移：扫描报告存储 + 诊断配置种子（对应小程序 commit 6b91ebe 的诊断链路上线）
-- 幂等：可重复执行。只做两件事，不碰其他表/账号。
-- 执行方式见 WorkLog: products/jw-beauty/2026-07-28-生产DB迁移指引.md

-- 1) 扫描报告表（Phase 1 已定义，生产一直未建）
CREATE TABLE IF NOT EXISTS scan_reports (
  id BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
  user_id BIGINT UNSIGNED NOT NULL,
  device_id VARCHAR(32) NULL,
  scanned_at DATETIME NULL,
  regions JSON NULL COMMENT 'array of per-region analysis',
  overall JSON NULL COMMENT 'array of overall tendencies',
  recommend_mask INT NOT NULL DEFAULT 0 COMMENT 'bitmask of regions recommended for care',
  recommend_plan JSON NULL COMMENT 'array of {region, mask, wave, wavelength, label_key, level, brightness}',
  raw_pd JSON NULL COMMENT 'raw PD samples for the calibration dataset (may be partial)',
  calibrated TINYINT NOT NULL DEFAULT 0 COMMENT 'whether thresholds were calibrated',
  created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (id),
  KEY idx_scan_reports_user_created (user_id, created_at),
  KEY idx_scan_reports_device_created (device_id, created_at),
  CONSTRAINT fk_scan_reports_user FOREIGN KEY (user_id) REFERENCES users (user_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

-- 2) 诊断配置种子（2026-07-28 新结构：极性/阈值/亮度/PD映射全部热调）
--    ON DUPLICATE KEY UPDATE 会覆盖已有的 diagnosis_config——当前生产从未配置过该键，
--    若执行前发现已有人工调过的值（见指引文档的核查步骤），先备份再执行。
