/api is gzip-compressed by middleware that runs after the handler returns, and the validator is computed over the uncompressed body. The compressed and identity forms of one payload therefore share a validator, which a strong ETag must not do -- it asserts byte-for-byte equality across representations (RFC 9110 8.8.1). Serve W/ instead. Weak comparison ignores W/ on both operands, so etagMatches now strips it from the served validator as well as from each candidate. Stripping only the candidate would make a weak served validator match nothing and silently disable every 304. Vary: Accept-Encoding stays. Weakening the validator makes revalidation correct, but it does not separate the two encodings in a shared cache.

WalkthroughThe change adds ETag-based revalidation for public JSON endpoints and a browser-visible session hint. Public bootstrap can skip anonymous refresh requests, while protected and sign-in routes still resolve authentication. Frontend public requests can retain cache validators.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to The change reduces unnecessary anonymous refreshes and enables conditional revalidation for public content while preserving existing response and rendering behavior; no actionable merge-blocking risk remains beyond normal checks and review.

优化首页匿名冷启动和公开内容接口的重复回源请求：没有会话时跳过确定失败的匿名 refresh；对 notice、home_page_content 以及 about、user-agreement、privacy-policy 使用 ETag/304 条件重验证，减少重复传输，同时保持现有 JSON 响应和内容渲染语义。
通过与 #7157 结合本次优化，首屏可从8个后台请求降低至2个源站后台请求，首屏速度提升75％

Issue facts
POST /api/user/auth/refresh并得到确定性的 401；公开且可后台编辑的内容接口受客户端全局Cache-Control: no-store影响，无法进行浏览器缓存重验证，也没有 ETag 条件请求。Change
新增会话提示 cookie 和前端内存提示，只有存在会话迹象时才启动公开 bootstrap refresh；需要鉴权的路由会调用
resolveAuthentication()，因此过期内存会话仍会回源确认。新增统一的serveRevalidatedJSON响应路径，以稳定 JSON 内容计算弱 ETag，在匹配If-None-Match时返回 304，否则返回原有{success, message, data}envelope。后台内容变化会改变哈希并立即失效；未将数据库配置改成静态 JSON，也未改变鉴权、权限或 HTML 内容净化/沙箱渲染。Research
