- identity.ts: 访客/会话 ID（30min 空闲轮换），localStorage 异常统一内存降级不冒泡（spec §4.5 红线） - context.ts: buildEnvContext/parseUtm/sanitizeUrl/pageContext；参数黑名单与 server URL_PARAM_DROP_PATTERNS 同源（整键精确匹配、大小写不敏感、保留空值） - 测试 21 过（含隐私模式降级、Edg 先于 Chrome、微信 UA 判定、iPad-Mobile 规格顺序锁定） Co-Authored-By: Claude Code <noreply@anthropic.com>
