- 旧流程先删 dist/TempLate 资源再构建，窗口期内请求 404 或命中根目录站点

- 新流程：构建 -> 同步 assets -> 最后替换 index.html -> 清理镜像目录陈旧文件

- 清理仅限 assets/ 与 tinymce/，保留 pages/ 等生产独有目录

-# GERP frontend deploy script: build and sync dist to production dir (TempLate/GERP)
+# GERP frontend deploy script: zero-downtime build and sync to production dir (TempLate/GERP)
 #
 # IMPORTANT: keep this file pure ASCII. PS 5.1 parses BOM-less UTF-8 files
 # using the ANSI codepage, so non-ASCII text would be garbled.
 #
-# Usage:
-#   1. Clean old artifacts (dist and TempLate/GERP/assets) so no stale hashes remain
-#   2. Full rebuild (vue-tsc type check + vite build)
-#   3. Sync dist to TempLate/GERP (index.html + assets)
-#   4. Verify TempLate matches dist exactly
+# Order matters (zero downtime):
+#   1. Build first (dist/) -- prod keeps serving the old build meanwhile
+#   2. Copy new assets/dirs (additive) -- old index.html still points to old
+#      assets, which are still present, so no request can 404
+#   3. Swap index.html last -- every asset it references already exists
+#   4. Prune stale files in the mirror dirs (assets / tinymce)
+#   5. Verify prod matches dist
 #
+# Never delete index.html / assets before the new build is ready: SubdomainView
+# (gvsds/apps/core/views.py) serves gerp.gvsds.com straight out of this directory.
+#
+# Usage:
 #   Run:  .\deploy.ps1
 #   (if execution policy blocks:  Set-ExecutionPolicy -Scope Process Bypass)
