+
+### 新增
+
+- **站点备份**：存储页导出 `.phost.tar.gz`（含 `pichost.db` 与全部图片），支持下载与任务进度
+- **站点恢复**：存储页或 setup 未初始化时从备份包恢复，支持预检与跳过/覆盖冲突
+- **跨后端同步**：在已配置存储后端之间拷贝图片并更新索引；后端卡片快捷「迁入 / 迁出」
+- **任务中心**：`backup_jobs` 记录最近导出/恢复/同步任务，失败可重试；列表分页
+- 运维 CLI：`backup-export`、`backup-restore`、`storage-sync`（`docker exec pichost …`）
+
+### 移除
+
+- 遗留目录迁移 CLI `migrate` / `migrate-to-single-images.mjs`（由启动索引同步与整站备份恢复替代）
+
+### 文档
+
+- [存储](./docs-site/guide/storage.md) 补充备份与迁移说明；更新截图；移除 v1.2 迁移专页
+
+## [1.2.8] - 2026-09-04

+### 改进
+
+- 双域名：保存或初始化时弹出风险确认（说明可能锁死及 `clear-domains` 恢复方式），不再强制校验当前 Host
+
+### 新增
+
+- 运维 CLI `clear-domains`：清除数据库中的网站域 / 图片域配置（`docker exec pichost clear-domains`）
+
+### 文档
+
+- FAQ、双域名、反向代理文档补充锁死原因与恢复步骤
+
+## [1.2.7] - 2026-09-03

+
+### 改进
+
+- README 补充技术栈说明
+
+### 移除
+
+- `/stats` 路由（不再兼容跳转）
+
+## [1.2.4] - 2026-08-31
+
+### 修复
+
+- 访问控制（Referer 防盗链）留空时仍会拦截外链图片：浏览器直开无 Referer 可访问，博客/论坛嵌入带 Referer 会 403 图裂；现仅在配置了白名单时才校验
+
+## [1.2.3] - 2026-08-30
+
+### 修复
+
+- 开启「简短图片链接」且按年/月分组时，纯文件名直链（如 `/xxx.webp`）误解析为 `images/xxx.webp` 导致 404；现先经 SQLite 索引反查完整 key
+
+## [1.2.2] - 2026-08-30
+
+### 修复
+
+- 双域名：设置页保存时误清空管理域（`site_base_url`）；仅改图片域时保护已有网站域配置
+- 双域名：设置 API 配置值与 request origin fallback 混淆，导致「当前生效」显示错误
+- 双域名：未配置的第三 Host（`pages.dev`、裸 IP 等）可绕过 Host 隔离访问后台
+
+### 改进
+
+- 设置 API 拆分 `siteBaseUrl` / `imageBaseUrl`（配置值）、`effective*`（直链）、`runtime`（当前访问检测）
+- `PATCH /api/settings` 增加 `domainSeparation` 字段与保存校验
+- 设置页：检测地址展示、关闭双域名确认、反代 Host 不一致警告；首次设置不再自动填入 origin
+- Host 中间件：双域名开启时对未知 Host 返回 404（开发 `localhost` 例外）
+- 文档站：新增 [更新日志](https://o96u.github.io/PicHost/guide/changelog)；重写 Cloudflare 部署说明；同步 FAQ / 双域名文档

+
+## [1.2.3] — 2026-08-30
+
+### Fix
+
+- **Short links + date-based storage**: bare filename URLs (e.g. `https://host/xxx.webp`) no longer map to flat `images/xxx.webp`; SQLite index resolves the full `images/YYYY/MM/xxx.webp` key so thumbnails and short links work again
+
+---
+
+## [1.2.2] — 2026-08-30
+
+> **Restart the service** after upgrading so middleware and API updates take effect.
+
+### Dual-domain settings & Host isolation
+
+#### Fixes
+
+| Issue | Description |
+| ----- | ----------- |
+| Site URL cleared by mistake | Saving Settings could write an empty `site_base_url` when disabling dual-domain or editing only the image URL |
+| Config vs effective URL mixed | `GET /api/settings` used to blend DB values with `request.origin`, confusing the Settings UI |
+| Third-host bypass | Unlisted hosts (`pages.dev`, bare IP, old image domains) were not blocked by middleware |
+
+#### Improvements
+
+**Settings API (`GET /api/settings`)**
+
+| Field | Meaning |
+| ----- | ------- |
+| `siteBaseUrl` / `imageBaseUrl` | **Configured** values (DB → env), no request fallback |
+| `effectiveSiteBaseUrl` / `effectiveImageBaseUrl` | **Link generation**, falls back to request origin when unset |
+| `runtime.currentOrigin` | Detected access URL (display only, not saved) |
+| `runtime.hostRole` | `site` / `image` / `unknown` / `single` |
+
+**Save API (`PATCH /api/settings`)**
+
+- New body field `domainSeparation` (`true` / `false`)
+- `domainSeparation: true` requires both URLs with different hostnames
+- `domainSeparation: false` allows clearing the site URL
+- Without `domainSeparation`, cannot clear `siteBaseUrl` while dual-domain is active
+
+**Settings / setup UI**
+
+- Form uses configured values; “Active” line shows `effective*`
+- Shows detected access URL; **no longer** auto-fills `window.location.origin`
+- “Use detected URL” button (opt-in)
+- Confirmation modal when disabling dual-domain
+- Warning when `hostRole === 'unknown'` with dual-domain on
+
+**Host middleware**
+
+- When dual-domain is on, unlisted hosts get **404** at the app layer (all methods)
+- `localhost` / `127.0.0.1` exempt in development
+- Complements Nginx `default_server` — use both layers in production
+
+#### Docs
+
+- Rewrote [Cloudflare deployment](./cloudflare-deployment.md)
+- Updated [Dual-domain separation](./domain-separation.md) for third-host blocking
+- Added this changelog page
+
+#### Upgrade notes
+
+- **No** database migration or CLI step
+- If the site URL was cleared earlier: re-enter it in **Settings**, or set `SITE_BASE_URL` in env and restart
+- Production: match proxy `server_name` to Settings; keep a default server block
+
+---
+
+## [1.2.1] — 2026-08-29
+
+### Added
+
+- Slide puzzle login captcha
+- VitePress docs site on GitHub Pages
+- `npm run docs:dev` / `docs:build` / `docs:preview`
+
+### Fixed
+
+- Gallery not refreshing after delete on stats page
+- Pagination jump with `type="number"` input
+- Copy-link format preference not persisting off home route
+- Captcha UI alignment
+
+### Improved
+
+- README trimmed; details moved to docs
+- Dual-domain docs: unknown Host risk, Cloudflare guide
+
+---
+
+## [1.2.0] — 2026-08-28
+
+### Changed
+
+- All images under `data/images/`; parallel top-level folders beside `images` are no longer used
+
+### Added
+
+- Startup index sync (disk scan, legacy key normalization, orphan cleanup)
+
+---
+
+## [1.1.x] summary
+
+| Version | Highlights |
+| ------- | ---------- |
+| 1.1.5 | API upload preview fix; file existence check before serve |
+| 1.1.4 | Date-based storage paths; site host blocks image URLs |

+# Cloudflare & preferred-edge deployment
+
+In dual-domain mode, PicHost distinguishes **site** vs **image** traffic from the request **Host** (and `X-Forwarded-Host` from a trusted reverse proxy). Cloudflare orange cloud, preferred-edge IPs, Workers, and Pages are all fine — as long as the hostname identity reaching PicHost stays correct.
+
+> **One-line rule:** The network path may change; the hostname identity must not — `admin → admin`, `img → img`, never `img → admin`.
+
+See [Dual-domain separation](./domain-separation.md) for middleware behavior and [Reverse proxy](./reverse-proxy.md) for general proxy requirements.
+
+---
+
+## Quick checklist
+
+| # | Check | Expected |
+| - | ----- | -------- |
+| 1 | Browser hostname | `admin.*` or `img.*`; do not mix IP / `pages.dev` |
+| 2 | Pages / Worker in the middle | Image host must **not** `fetch(admin…)` |
+| 3 | Reverse-proxy upstream | Both hostnames → `http://127.0.0.1:6892` |
+| 4 | Nginx `proxy_set_header Host` | `$host` (preserve client hostname) |
+| 5 | PicHost settings | `SITE_BASE_URL` / `IMAGE_BASE_URL` match `server_name` |
+| 6 | Port `6892` | Reachable only from localhost or internal proxy |
+
+---
+
+## Recommended layout
+
+Both hostnames go through Cloudflare (proxied) and **independently** reverse-proxy to one PicHost instance:
+
+```mermaid
+flowchart TB
+  internet[Internet]
+  cf[Cloudflare proxied]
+  admin[admin.example.com]
+  img[img.example.com]
+  panel[1Panel / Nginx]
+  app[PicHost :6892]
+
+  internet --> cf
+  cf --> admin
+  cf --> img
+  admin --> panel
+  img --> panel
+  panel --> app
+```
+
+```env
+SITE_BASE_URL=https://admin.example.com
+IMAGE_BASE_URL=https://img.example.com
+```
+
+```text
+admin.example.com → http://127.0.0.1:6892
+img.example.com   → http://127.0.0.1:6892
+```
+
+You do **not** need separate ports for “frontend / backend / images” — one PicHost instance on port `6892` is enough.
+
+### Site hostname ≠ frontend domain
+
+| Hostname | Serves |
+| -------- | ------ |
+| `admin.example.com` | Admin UI, login, settings, gallery, API, upload |
+| `img.example.com` | Image delivery, hotlinks, CDN |
+
+Use **site / image hostname**, not “frontend / backend”. PicHost does **not** require `frontend :3000 + backend :6892` in production.
+
+---
+
+## Orange cloud & preferred edge
+
+**DNS Proxied (orange cloud)** is normal and recommended:
+
+```text
+admin.example.com, img.example.com
+  A/CNAME → origin → Proxied
+```
+
+Opening `admin.example.com` should yield `Host: admin.example.com` at PicHost; `img.example.com` should yield `Host: img.example.com`.
+
+**Preferred-edge** setups (alternate IPs, entry hostnames) are also fine. Preferred routing may change the path to Cloudflare’s edge, but must **not** rewrite the image hostname’s origin identity to the site hostname:
+
+```text
+admin → CF → admin.example.com → origin → PicHost
+img   → CF → img.example.com   → origin → PicHost
+```
+
+---
+
+## 6. Typical bad topologies
+
+These patterns break Host isolation even when the browser still shows the image hostname:
+
+### ❌ Bad 1: Image host fetches site host
+
+```mermaid
+flowchart LR
+  user[User on img.example.com]
+  worker[Pages / Worker]
+  admin[fetch admin.example.com]
+  app[PicHost]
+
+  user --> worker --> admin --> app
+```
+
+The last hop has `Host: admin.example.com`, so PicHost treats it as site traffic — `https://img.example.com/` may show the admin UI. This is **Host rewrite**, not a cache bug.
+
+### ❌ Bad 2: Preferred proxy upstreams to site host
+
+```text
+img.example.com → preferred hostname → admin.example.com → origin
+```
+
+Even for routing only, using the site hostname as upstream breaks image isolation.
+
+### ❌ Bad 3: Public exposure of port 6892
+
+```text
+any host / IP:6892 → PicHost
+```
+
+Users can bypass Cloudflare and Nginx `server_name` rules. Port `6892` should be reachable only from `127.0.0.1` or an internal reverse proxy.
+
+### ✅ Correct pattern
+
+```text
+admin → admin → PicHost
+img   → img   → PicHost
+```
+
+Do **not** use Pages / Workers as a **full-site reverse proxy** for PicHost (extra `pages.dev` / `workers.dev` entry points). PicHost needs `node-server`, SQLite, `sharp`, and local `data/` — it **cannot** run as a Node app on Pages/Workers. Keep Docker/VPS for the app; use orange-cloud DNS and optional R2 on CF.
+
+---
+
+## Workers / Pages guidance
+
+If you only need headers, auth, Referer rules, logging, or cache — and PicHost remains your origin:
+
+| Prefer | Avoid |
+| ------ | ----- |
+| `img.example.com` → **Worker Route** → existing `img` origin | `img` → Worker → `fetch(admin.example.com)` |
+
+Cloudflare recommends [Routes](https://developers.cloudflare.com/workers/configuration/routing/routes/) when an external origin already exists, rather than [Custom Domains](https://developers.cloudflare.com/workers/configuration/routing/custom-domains/) used to chain cross-host `fetch()`.
+
+Code like this on the image hostname is a smoking gun:
+
+```js
+fetch(`https://admin.example.com${url.pathname}`)
+```
+
+---
+
+## Nginx / 1Panel layout
+
+Two `server` blocks, same upstream. Critical line: `proxy_set_header Host $host;`
+
+```nginx
+server {
+    server_name admin.example.com;
+    location / {
+        proxy_pass http://127.0.0.1:6892;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        client_max_body_size 12m;
+    }
+}
+
+server {
+    server_name img.example.com;
+    location / {
+        proxy_pass http://127.0.0.1:6892;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+}
+
+# Reject bare IP and unknown hostnames (strongly recommended)
+server {
+    listen 80 default_server;
+    listen 443 ssl default_server;
+    server_name _;
+    return 444;
+}
+```
+
+With orange cloud, restrict the origin firewall to **[Cloudflare IP ranges](https://www.cloudflare.com/ips/)** only.
+
+---
+
+## Two-layer Host protection
+
+Use reverse proxy and application layers **together**:
+
+| Layer | Role |
+| ----- | ---- |
+| **Nginx default server** | Reject bare IP, `pages.dev`, and other undeclared hostnames |
+| **PicHost middleware (v1.2.x+)** | When dual-domain is on, unconfigured hosts get 404 at the app (`localhost` / `127.0.0.1` exempt in development) |
+
+Even with app-layer blocking, keep a default server at the proxy to reduce junk traffic to PicHost.
+
+---
+
+## X-Forwarded-Host
+
+PicHost may consult `X-Forwarded-Host` behind a reverse proxy, but that header is **forgeable** by clients. Therefore:
+
+- Do not expose port `6892` publicly
+- Only trusted proxies should reach the app
+- Prefer keeping `Host` correct from the first hop
+
+---
+
+## Troubleshooting: admin UI on image hostname?
+
+**Inspect the proxy chain first — do not purge CF cache first.**
+
+Cache issues usually mean stale JS/CSS/images or occasional 404s. If `/`, `/login`, and `/settings` work **reliably** on the image host, the Host was almost certainly rewritten.
+
+```text
+① Browser hostname?
+② Pages / Worker / preferred proxy in the middle?
+③ What URL does the proxy fetch?
+④ Does it fetch admin.example.com?
+⑤ Which Host does 1Panel / PicHost see?
+```

 ## Security notes
 
-### Middleware only splits the two configured hostnames
+### Middleware isolation and third hosts
 
 PicHost uses the request **Host** (and `X-Forwarded-Host` when proxied) to decide site vs image domain:
 
 - **Image host**: non-image paths (e.g. `/`, `/settings`) → 404
 - **Site host**: image URL paths (e.g. `/images/...`) → 404
+- **Unconfigured third hosts** (e.g. `*.pages.dev`, bare IP, old image domains): **from v1.2.x the app returns 404 for all methods** (`localhost` / `127.0.0.1` are exempt in development for `npm run dev`)
 
-If the Host is **neither** the configured site nor image hostname (e.g. `localhost`, the server **public IP**, Cloudflare **Pages** `*.pages.dev`, **Workers** `*.workers.dev`, or any other unlisted name), **the app does not block the request today** — admin and API may still be reachable. This is not about hyphenated or long domain names; it is an extra entry point outside your dual-domain pair.
+This is independent of hyphenated or long domain names. Older versions did not block third hosts; rely on a reverse-proxy default server as a complement in production.

+## Admin 404 / locked out after dual-domain setup?

+
 ## Why can admin load on pages.dev / workers.dev / IP with dual-domain?
 
-Dual-domain isolation only splits paths on the **configured site and image hostnames**. Other Host values (`localhost`, public IP, Cloudflare **Pages** `*.pages.dev`, **Workers** `*.workers.dev`, etc.) are **not blocked today**, so admin may appear on unexpected URLs.
+**From v1.2.2:** when dual-domain is on, PicHost returns **404** for Host values **other than** the configured site and image hostnames (`localhost` / `127.0.0.1` exempt in development). See [Changelog](./changelog.md#1-2-2-2026-08-30).
 
-Common cause: **full-site reverse proxy** via Pages/Workers on top of orange-cloud DNS, or an origin that accepts any Host / bare IP.
+If admin still loads:
 
-Fix: use only the two configured domains; add a default `server_name` block; with orange cloud, allow only CF IPs on the origin. See [Security notes](./domain-separation.md#security-notes).
+1. **Dual-domain not active** (image URL set but site URL empty) — neither path split nor third-host blocking applies
+2. **Proxy rewrote Host to site hostname** — e.g. Pages/Worker `fetch(admin…)` on the image hostname
