53bfb1b7c0 feat(session): invalidate all sessions on role/status change via generation 
users 表加 session_generation 列。get_user_by_token 缓存命中后回查 DB
generation，不匹配则逐出缓存并视为未登录，消除降级/封禁用户的权限残留
窗口（H2）。新增 invalidate_user_sessions 用于 bump generation，当前仓库
无运行时角色变更入口，作为未来用户管理功能的基础设施预留。

- 迁移 012：ADD COLUMN IF NOT EXISTS session_generation INT DEFAULT 0
- User/SessionUser 同步加字段，From<User> 如实传递
- 缓存校验走主键查询，亚毫秒级

79cb809010 perf(posts): add optional pagination to get_posts_by_tag, fix total count 
- get_posts_by_tag 现接受 page/per_page 可选参数；两者均 None 时返回全部
  （上限 200，用于无翻页 UI 的标签详情页），均提供时走标准分页。
- 修正 total：不再用 posts.len()，改为真实 COUNT(*)，即使被 LIMIT 截断
  也返回完整计数。
- 新增 CacheKey::PostsByTagPage 分页缓存键，与不分页键 PostsByTag 共存。
- 前端 tags.rs 传 (None, None) 保持原全部展示行为。

04737300e6 feat(comments): add complete comment system with guest commenting, moderation, and admin UI 
Implements a fully self-built comment system for the blog:

Data layer:
- comments table with BIGSERIAL PK, parent_id self-reference (ON DELETE SET NULL),
  depth tracking (max 20), status workflow (pending/approved/spam/trash),
  content hashing for dedup, GDPR consent tracking, IP/UA storage with auto-purge
- 5 partial indexes optimized for read patterns
- updated_at auto-trigger

API (9 Dioxus server functions):
- Public: get_comments, get_comment_count, create_comment
- Admin: get_pending_comments, get_pending_count, get_all_comments,
  approve_comment (with ancestor auto-approval), spam_comment, trash_comment,
  batch_update_comment_status

Security:
- Function-level rate limiting (1/sec, burst 5) via FullstackContext IP extraction
- Input validation (name, email, URL scheme, content length, consent)
- Parent chain validation (must be approved, same post)
- Strict comment Markdown renderer (headings→strong, no img/id/data URIs, nofollow links)
- Honeypot anti-spam field
- 5-minute dedup window via SHA-256 content hash

Frontend:
- CommentSection with SuspenseBoundary isolation
- Flat-list rendering with depth-based CSS indentation (responsive)
- Gravatar via cravatar.cn (server-computed, email never exposed)
- Inline reply forms (one-at-a-time via Signal)
- Admin action buttons (approve/spam/delete) visible per-comment
- CommentForm with privacy consent, Markdown hint, loading states

Admin:
- /admin/comments page with status tabs, batch operations, pagination
- Pending count badge on admin dashboard

Infrastructure:
- Shared get_current_admin_user moved from posts/helpers to auth module
- COMMENT_LIMITER rate limiter tier
- Moka caches (60s TTL for comments, 10s for pending count)
- IP/UA purge background task (daily, 90-day retention)

311ddbe204 perf(cache): cache COUNT(*) result separately to avoid redundant queries 
- Add TotalPublishedPosts cache key for reusing total count across pages
- list_published_posts now checks total cache before running COUNT(*)
- Add note to get_posts_by_tag about total = posts.len() assumption
- Remove unused invalidate_total_published_posts helper

62e2045b35 feat: add cache module with moka-backed post/tag/stats caching 
- Create src/cache.rs with CacheKey enum, moka cache instances,
  getter/setter functions, and invalidation helpers.
- TTLs: post list 60s, tags 300s, single post 600s, stats 60s,
  tag posts 120s.
- Register mod cache in src/main.rs.
- All cache internals gated behind #[cfg(feature = "server")]
