 # Changelog
 
+## Changes 10/27/2025 (v1.6.9)
+
+release(v1.6.9): feat(core) localize assets, harden headers, and speed up load
+
+- index.html: drop all CDNs in favor of local /vendor assets
+  - add versioned cache-busting query (?v=…) on CSS/JS
+  - wire version.js for APP_VERSION and numeric cache key
+- public/vendor/: add pinned copies of:
+  - bootstrap 4.5.2, codemirror 5.65.5 (+ themes/modes), dompurify 2.4.0,
+    fuse.js 6.6.2, resumable.js 1.1.0
+- fonts: add self-hosted Material Icons + Roboto (latin + latin-ext) with
+  vendor CSS (material-icons.css, roboto.css)
+
+- fileEditor.js: load CodeMirror modes from local vendor with ?v=APP_VERSION_NUM,
+  keep timeout/plain-text fallback, no SRI (same-origin)
+- dragAndDrop.js: nudge zonesToggle 65px left to sit tighter to the logo
+
+- styles.css: prune/organize rules and add small utility classes; move 3P
+  font CSS to /css/vendor/
+
+- .htaccess: security + performance overhaul
+  - Content-Security-Policy: default-src 'self'; img-src include data: and blob:
+  - version-aware caching: HTML/version.js = no-cache; assets with ?v= = 1y immutable
+  - correct MIME for fonts/SVG; enable Brotli/Gzip (if available)
+  - X-Frame-Options, X-Content-Type-Options, Referrer-Policy, HSTS, Permissions-Policy
+  - disable TRACE; deny dotfiles; prevent directory listing
+
+- .gitattributes: mark vendor/minified as linguist-vendored, treat assets as
+  binary in diffs, exclude CI/resources from source archives
+
+- docs/licensing:
+  - add licenses/ and THIRD_PARTY.md with upstream licenses/attribution
+  - README: add “License & Credits” section with components and licenses
+
+- CI: (sync-changelog) stamp asset cache-busters to the numeric release
+  (e.g. ?v=1.6.9) and write window.APP_VERSION in version.js before Docker build
+
+perf: site loads significantly faster with local assets + compression + long-lived caching
+security: CSP, strict headers, and same-origin assets reduce XSS/SRI/CORS risk
+
+Refs: #performance #security

+
+## Changes 10/25/2025 (v1.6.8)
+
+release(v1.6.8): fix(ui) prevent Extract/Create flash on refresh; remember last folder
+
+- Seed `currentFolder` from `localStorage.lastOpenedFolder` (fallback to "root")
+- Stop eager `loadFileList('root')` on boot; defer initial load to resolved folder
+- Hide capability-gated actions by default (`#extractZipBtn`, `#createBtn`) to avoid pre-auth flash
+- Eliminates transient root state when reloading inside a subfolder
+
+User-visible: refreshing a non-root folder no longer flashes Root items or privileged buttons; app resumes in the last opened folder.
+
+---
+
+## Changes 10/25/2025 (v1.6.7)
+
+release(v1.6.7): Folder Move feature, stable DnD persistence, safer uploads, and ACL/UI polish
+
+### 📂 Folder Move (new major feature)
+
+**Drag & Drop to move folder, use context menu or Move Folder button**  
+
+- Added **Move Folder** support across backend and UI.  
+  - New API endpoint: `public/api/folder/moveFolder.php`  
+  - Controller and ACL updates to validate scope, ownership, and permissions.  
+  - Non-admins can only move within folders they own.  
+  - `ACL::renameTree()` re-keys all subtree ACLs on folder rename/move.  
+- Introduced new capabilities:
+  - `canMoveFolder`
+  - `canMove` (UI alias for backward compatibility)
+- New “Move Folder” button + modal in the UI with full i18n strings (`i18n.js`).  
+- Action button styling and tooltip consistency for all folder actions.
+
+### 🧱 Drag & Drop / Layout Improvements
+
+- Fixed **random sidebar → top zone jumps** on refresh.  
+- Cards/panels now **persist exactly where you placed them** (`userZonesSnapshot`)  
+  — no unwanted repositioning unless the window is resized below the small-screen threshold.
+- Added hysteresis around the 1205 px breakpoint to prevent flicker when resizing.  
+- Eliminated the 50 px “ghost” gutter with `clampSidebarWhenEmpty()`:
+  - Sidebar no longer reserves space when collapsed or empty.  
+  - Temporarily “unclamps” during drag so drop targets remain accurate and full-width.  
+- Removed forced 800 px height on drag highlight; uses natural flex layout now.  
+- General layout polish — smoother transitions when toggling *Hide/Show Panels*.
+
+### ☁️ Uploads & UX
+
+- Stronger folder sanitization and safer base-path handling.  
+- Fixed subfolder creation when uploading directories (now builds under correct parent).  
+- Improved chunk error handling and metadata key correctness.  
+- Clearer success/failure toasts and accurate filename display from server responses.
+
+### 🔐 Permissions / ACL
+
+- Simplified file rename checks — now rely solely on granular `ACL::canRename()`.  
+- Updated capability lists to include move/rename operations consistently.
+
+### 🌐 UI / i18n Enhancements
+
+- Added i18n strings for new “Move Folder” prompts, modals, and tooltips.  
+- Minor UI consistency tweaks: button alignment, focus states, reduced-motion support.

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.
