chore(release): set APP_VERSION to v1.9.4 [skip ci]

- Lazy folder tree via /api/folder/listChildren.php with cursor pagination
- ACL-safe chevrons using hasSubfolders from server; no file-count leaks
- BFS smart initial folder selection + respect lastOpenedFolder
- Locked nodes are expandable but not selectable
- “Load more” UX (light & dark) for huge directories

Closes #66

 # Changelog
 
+## Changes 11/13/2025 (v1.9.4)
+
+release(v1.9.4): lazy folder tree, cursor pagination, ACL-safe chevrons, and “Load more” (closes #66)
+
+**Big focus on folder management performance & UX for large libraries.**
+
+feat(folder-tree):
+
+- Lazy-load children on demand with cursor-based pagination (`nextCursor` + `limit`), including inline “Load more” row.
+- BFS-based initial selection: if user can’t view requested/default folder, auto-pick the first accessible folder (but stick to (Root) when user can view it).
+- Persisted expansion state across reloads; restore saved path and last opened folder; prevent navigation into locked folders (shows i18n toast instead).
+- Breadcrumb now respects ACL: clicking a locked crumb toggles expansion only (no navigation).
+- Live chevrons from server truth: `hasSubfolders` is computed server-side to avoid file count probes and show correct expanders (even when a direct child is unreadable).
+- Capabilities-driven toolbar enable/disable for create/move/rename/color/delete/share.
+- Color-carry on move/rename + expansion state migration so moved/renamed nodes keep colors and stay visible.
+- Root DnD honored only when viewable; structural locks disable dragging.
+
+perf(core):
+
+- New `FS.php` helpers: safe path resolution (`safeReal`), segment sanitization, symlink defense, ignore/skip lists, bounded child counting, `hasSubfolders`, and `hasReadableDescendant` (depth-limited).
+- Thin caching for child lists and counts, with targeted cache invalidation on move/rename/create/delete.
+- Bounded concurrency for folder count requests; short timeouts to keep UI snappy.
+
+api/model:
+
+- `FolderModel::listChildren(...)` now returns items shaped like:
+  `{ name, locked, hasSubfolders, nonEmpty? }`
+  - `nonEmpty` included only for unlocked nodes (prevents side-channel leakage).
+  - Locked nodes are only returned when `hasReadableDescendant(...)` is true (preserves legacy “structural visibility without listing the entire tree” behavior).
+- `public/api/folder/listChildren.php` delegates to controller/model; `isEmpty.php` hardened; `capabilities.php` exposes `canView` (or derived) for fast checks.
+- Folder color endpoints gate results by ACL so users only see colors for folders they can at least “own-view”.
+
+ui/ux:
+
+- New “Load more” row (`<li class="load-more">`) with dark-mode friendly ghost button styling; consistent padding, focus ring, hover state.
+- Locked folders render with padlock overlay and no DnD; improved contrast/spacing; icons/chevrons update live as children load.
+- i18n additions: `no_access`, `load_more`, `color_folder(_saved|_cleared)`, `please_select_valid_folder`, etc.
+- When a user has zero access anywhere, tree selects (Root) but shows `no_access` instead of “No files found”.
+
+security:
+
+- Stronger path traversal + symlink protections across folder APIs (all joins normalized, base-anchored).
+- Reduced metadata leakage by omitting `nonEmpty` for locked nodes and depth-limiting descendant checks.
+
+fixes:
+
+- Chevron visibility for unreadable intermediate nodes (e.g., “Files” shows a chevron when it contains a readable “Resources” descendant).
+- Refresh now honors the actively viewed folder (session/localStorage), not the first globally readable folder.
+
+chore:
+
+- CSS additions for locked state, tree rows, and dark-mode ghost buttons.
+- Minor code cleanups and comments across controller/model and JS tree logic.
+
+---
+
+## Changes 11/11/2025 (v1.9.3)
+
+release(v1.9.3): unify folder icons across tree & strip, add “paper” lines, live color sync, and vendor-aware release
+
+- UI / Icons
+  - Replace Material icon in folder strip with shared `folderSVG()` and export it for reuse. Adds clipPaths, subtle gradients, and `shape-rendering: geometricPrecision` to eliminate the tiny seam.
+  - Add ruled “paper” lines and blue handwriting dashes; CSS for `.paper-line` and `.paper-ink` included.
+  - Match strokes between tree (24px) and strip (48px) so both look identical; round joins/caps to avoid nicks.
+  - Polish folder strip layout & hover: tighter spacing, centered icon+label, improved wrapping.
+
+- Folder color & non-empty detection
+  - Live color sync: after saving a color we dispatch `folderColorChanged`; strip repaints and tree refreshes.
+  - Async strip icon: paint immediately, then flip to “paper” if the folder has contents. HSL helpers compute front/back/stroke shades.
+
+- FileList strip
+  - Render subfolders with `<span class="folder-svg">` + name, wire context menu actions (move, color, share, etc.), and attach icons for each tile.
+
+- Exports & helpers
+  - Export `openColorFolderModal(...)` and `openMoveFolderUI(...)` for the strip and toolbar; use `refreshFolderIcon(...)` after ops to keep icons current.
+
+- AppCore
+  - Update file upload DnD relay hook to `#fileList` (id rename).
+
+- CSS tweaks
+  - Bring tree icon stroke/paint rules in line with the strip, add scribble styles, and adjust margins/spacing.
+
+- CI/CD (release)
+  - Build PHP dependencies during release: setup PHP 8.3 + Composer, cache downloads, install into `staging/vendor/`, exclude `vendor/` from placeholder checks, and ship artifact including `vendor/`.
+
+- Changelog highlights
+  - Sharper, seam-free folder SVGs shared across tree & strip, with paper lines + handwriting accents.
+  - Real-time folder color propagation between views.
+  - Folder strip switched to SVG tiles with better layout + context actions.
+  - Release pipeline now produces a ready-to-run zip that includes `vendor/`.
+
+---
+
+## Changes 11/10/2025 (v1.9.2)
+
+release(v1.9.2): Upload modal + DnD relay from file list (with robust synthetic-drop fallback)
+
+- New “Upload file(s)” action in Create menu:
+  - Adds `<li id="uploadOption">` to the dropdown.
+  - Opens a reusable Upload modal that *moves* the existing #uploadCard into the modal (no cloning = no lost listeners).
+  - ESC / backdrop / “×” close support; focus jumps to “Choose Files” for fast keyboard flow.
+
+- Drag & Drop from file list → Upload:
+  - Drag-over on #fileListContainer shows drop-hover and auto-opens the Upload modal after a short hover.
+  - On drop, waits until the modal’s #uploadDropArea exists, then relays the drop to it.
+  - Uses a resilient relay: attempts to attach DataTransfer to a synthetic event; falls back to a stash.
+
+- Synthetic drop fallback:
+  - Introduces window.__pendingDropData (cleared after use).
+  - upload.js now reads e.dataTransfer || window.__pendingDropData to accept relayed drops across browsers.
+
+- Implementation details:
+  - fileActions.js: adds openUploadModal()/closeUploadModal() with a hidden sentinel to return #uploadCard to its original place on close.
+  - appCore.js: imports openUploadModal, adds waitFor() helper, and wires dragover/leave/drop logic for the relay.
+  - index.html: adds Upload option to the Create menu and the #uploadModal scaffold.
+
+- UX/Safety:
+  - Defensive checks if modal/card isn’t present.
+  - No backend/API changes; CSRF/auth unchanged.
+
+Files touched: public/js/upload.js, public/js/fileActions.js, public/js/appCore.js, public/index.html

+
+## Changes 11/9/2025 (v1.9.1)
+
+release(v1.9.1): customizable folder colors + live preview; improved tree persistence; accent button; manual sync script
+
+### Highlights v1.9.1
+
+- 🎨 Per-folder colors with live SVG preview and consistent styling in light/dark modes.
+- 📄 Folder icons auto-refresh when contents change (no full page reload).
+- 🧭 Drag-and-drop breadcrumb fallback for folder→folder moves.
+- 🛠️ Safer upgrade helper script to rsync app files without touching data.
+
+- feat(colors): add per-folder color customization
+  - New endpoints: GET /api/folder/getFolderColors.php and POST /api/folder/saveFolderColor.php
+    - AuthZ: reuse canRename for “customize folder”, validate hex, and write atomically to metadata/folder_colors.json.
+    - Read endpoint filters map by ACL::canRead before returning to the user.
+  - Frontend: load/apply colors to tree rows; persist on move/rename; API helpers saveFolderColor/getFolderColors.
+
+- feat(ui): color-picker modal with live SVG folder preview
+  - Shows preview that updates as you pick; supports Save/Reset; protects against accidental toggle clicks.
+
+- feat(controls): “Color folder” button in Folder Management card
+  - New `.btn-color-folder` with accent palette (#008CB4), hover/active/focus states, dark-mode tuning; event wiring gated by caps.
+
+- i18n: add strings for color UI (color_folder, choose_color, reset_default, save_color, folder_color_saved, folder_color_cleared).
+
+- ux(tree): make expansion state more predictable across refreshes
+  - `expandTreePath(path, {force,persist,includeLeaf})` with persistence; keep ancestors expanded; add click-suppression guard.
+
+- ux(layout): center the folder-actions toolbar; remove left padding hacks; normalize icon sizing.
+
+- chore(ops): add scripts/manual-sync.sh (safe rsync update path, preserves data dirs and public/.htaccess).
+
+---
+
+## Changes 11/9/2025 (v1.9.0)
+
+release(v1.9.0): folder tree UX overhaul, fast ACL-aware counts, and .htaccess hardening
+
+feat(ui): modern folder tree
+
+- New crisp folder SVG with clear paper insert; unified yellow/orange palette for light & dark
+- Proper ARIA tree semantics (role=treeitem, aria-expanded), cleaner chevrons, better alignment
+- Breadcrumb tweaks (› separators), hover/selected polish
+- Prime icons locally, then confirm via counts for accurate “empty vs non-empty”
+
+feat(api): add /api/folder/isEmpty.php via controller/model
+
+- public/api/folder/isEmpty.php delegates to FolderController::stats()
+- FolderModel::countVisible() enforces ACL, path safety, and short-circuits after first entry
+- Releases PHP session lock early to avoid parallel-request pileups
+
+perf: cap concurrent “isEmpty” requests + timeouts
+
+- Small concurrency limiter + fetch timeouts
+- In-memory result & inflight caches for fewer network hits
+
+fix(state): preserve user expand/collapse choices
+
+- Respect saved folderTreeState; don’t auto-expand unopened nodes
+- Only show ancestors for visibility when navigating (no unwanted persists)
+
+security: tighten .htaccess while enabling WebDAV
+
+- Deny direct PHP except /api/*.php, /api.php, and /webdav.php
+- AcceptPathInfo On; keep path-aware dotfile denial
+
+refactor: move count logic to model; thin controller action
+
+chore(css): add unified “folder tree” block with variables (sizes, gaps, colors)
+
+Files touched: FolderModel.php, FolderController.php, public/js/folderManager.js, public/css/styles.css, public/api/folder/isEmpty.php (new), public/.htaccess
+
+---
+
+## Changes 11/8/2025 (v1.8.13)
+
+release(v1.8.13): ui(dnd): stabilize zones, lock sidebar width, and keep header dock in sync
+
+- dnd: fix disappearing/overlapping cards when moving between sidebar/top; return to origin on failed drop
+- layout: placeCardInZone now live-updates top layout, sidebar visibility, and toggle icon
+- toggle/collapse: move ALL cards to header on collapse, restore saved layout on expand; keep icon state synced; add body.sidebar-hidden for proper file list expansion; emit `zones:collapsed-changed`
+- header dock: show dock whenever icons exist (and on collapse); hide when empty
+- responsive: enforceResponsiveZones also updates toggle icon; stash/restore behavior unchanged
+- sidebar: hard-lock width to 350px (CSS) and remove runtime 280px minWidth; add placeholder when empty to make dropping back easy
+- CSS: right-align header dock buttons, centered “Drop Zone” label, sensible min-height; dark-mode safe
+- refactor: small renames/ordering; remove redundant z-index on toggle; minor formatting
+
+---
+
+## Changes 11/8/2025 (v1.8.12)
+
+release(v1.8.12): auth UI & DnD polish — show OIDC, auto-SSO, right-aligned header icons
+
+- auth (public/js/main.js)
+  - Robust login options: tolerate key variants (disableFormLogin/disable_form_login, etc.).
+  - Correctly show/hide wrapper + individual methods (form/OIDC/basic).
+  - Auto-SSO when OIDC is the only enabled method; add opt-out with `?noauto=1`.
+  - Minor cleanup (SW register catch spacing).
+
+- drag & drop (public/js/dragAndDrop.js)
+  - Reworked zones model: Sidebar / Top (left/right) / Header (icon+modal).
+  - Persist user layout with `userZonesSnapshot.v2` and responsive stash for small screens.
+  - Live UI sync: toggle icon (`material-icons`) updates immediately after moves.
+  - Smarter small-screen behavior: lift sidebar cards ephemerally; restore only what belonged to sidebar.
+  - Cleaner header icon modal plumbing; remove legacy/dead code.
+
+- styles (public/css/styles.css)
+  - Header drop zone fills remaining space and right-aligns its icons.
+
+UX:
+
+- OIDC button reliably appears when form/basic are disabled.
+- If OIDC is the sole method, users are taken straight to the provider (unless `?noauto=1`).
+- Header icons sit with the other header actions (right-aligned), and the toggle icon reflects layout changes instantly.
+
+---
+
+## Changes 11/8/2025 (v1.8.11)
+
+release(v1.8.11): fix(oidc): always send PKCE (S256) and treat empty secret as public client
+
+- Force PKCE via setCodeChallengeMethod('S256') so Authelia’s public-client policy is satisfied.
+- Convert empty OIDC client secret to null to correctly signal a public client.
+- Optional commented hook to switch token endpoint auth to client_secret_post if desired.
+- OIDC_TOKEN_ENDPOINT_AUTH_METHOD added to config.php
+
+---
+
+## Changes 11/8/2025 (v1.8.10)
+
+release(v1.8.10): theme-aware media modal, stronger file drag-and-drop, unified progress color, and favicon overhaul
+
+UI/UX — Media modal
+
+- Add fixed top bar to avoid filename/controls overlapping native media chrome; keep hover-on-stage look.
+- Show a Material icon by file type next to the filename (image/video/pdf/code/arch/txt, with fallback).
+- Restore “X” behavior and make hover theme-aware (red pill + white ‘X’ in light, red pill + black ‘X’ in dark).
+
+Video/Image controls
+
+- Top-right action icons use theme-aware styles and align with the filename row.
+- Prev/Next paddles remain high-contrast and vertically centered within the stage.
+
+Progress badges (list & modal)
+
+- Standardize “in-progress” to darker orange (#ea580c) for better contrast in light/dark; update CSS and list badge rendering.
+
+Drag & drop
+
+- Support multi-select drags with a clean JSON payload + text fallback; nicer drag ghost.
+- More resilient drops: accept data-dest-folder, safer JSON parse, early guards, and better toasts.
+- POST move now sends Accept header, uses global CSRF, and refreshes the active view on success.
+
+Editor & ONLYOFFICE
+
+- Full-screen OO modal with preconnect, optional hidden warm-up to reduce first-open latency, and live theme sync.
+- CodeMirror path: fix theme/mode setters (use `cm`) and tighten dynamic mode loading.
+
+Assets & polish
+
+- Swap in full favicon stack (SVG + PNG 512/32/16 + ICO) and set theme-color; cache-busted via `{{APP_QVER}}`.
+- Refresh `logo.svg` (accessibility, cleaner handles/gradients).
+
+Also added: refreshed resource images and new logo sizes (logo-16, logo-32, logo-64, etc.) for crisper favicons and embeds.
+
+---
+
+## Changes 11/7/2025 (v1.8.9)
+
+release(v1.8.9): fix(oidc, admin): first-save Client ID/Secret (closes #64)
+
+- adminPanel.js:
+  - Masked inputs without a saved value now start with data-replace="1".
+  - handleSave() now sends oidc.clientId / oidc.clientSecret on first save (no longer requires clicking “Replace” first).
+
+---
+
+## Changes 11/7/2025 (v1.8.8)
+
+release(v1.8.8): background ZIP jobs w/ tokenized download + in‑modal progress bar; robust finalize; janitor cleanup — closes #60
+
+**Summary**
+This release moves ZIP creation off the request thread into a **background worker** and switches the client to a **queue > poll > tokenized GET** download flow. It fixes large multi‑GB ZIP failures caused by request timeouts or cross‑device renames, and provides a resilient in‑modal progress experience. It also adds a 6‑hour janitor for temporary tokens/logs.
+
+**Backend** changes:
+
+- Add **zip status** endpoint that returns progress and readiness, and **tokenized download** endpoint for one‑shot downloads.
+- Update `FileController::downloadZip()` to enqueue a job and return `{ token, statusUrl, downloadUrl }` instead of streaming a blob in the POST response.
+- Implement `spawnZipWorker()` to find a working PHP CLI, set `TMPDIR` on the same filesystem as the final ZIP, spawn with `nohup`, and persist PID/log metadata for diagnostics.
+- Serve finished ZIPs via `downloadZipFile()` with strict token/user checks and streaming headers; unlink the ZIP after successful read.
+
+New **Worker**:
+
+- New `src/cli/zip_worker.php` builds the archive in the background.
+- Writes progress fields (`pct`, `filesDone`, `filesTotal`, `bytesDone`, `bytesTotal`, `current`, `phase`, `startedAt`, `finalizeAt`) to the per‑token JSON.
+- During **finalizing**, publishes `selectedFiles`/`selectedBytes` and clears incremental counters to avoid the confusing “N/N files” display before `close()` returns.
+- Adds a **janitor**: purge `.tokens/*.json` and `.logs/WORKER-*.log` older than **6 hours** on each run.
+
+New **API/Status Payload**:
+
+- `zipStatus()` exposes `ready` (derived from `status=done` + existing `zipPath`), and includes `startedAt`/`finalizeAt` for UI timers.
+- Returns a prebuilt `downloadUrl` for a direct handoff once the ZIP is ready.
+
+**Frontend (UX)** changes:
+
+- Replace blob POST download with **enqueue → poll → tokenized GET** flow.
+- Native `<progress>` bar now renders **inside the modal** (no overflow/jitter).
+- Shows determinate **0–98%** during enumeration, then **locks at 100%** with **“Finalizing… mm:ss — N files, ~Size”** until the download starts.
+- Modal closes just before download; UI resets for the next operation.
+
+Added **CSS**:
+
+- Ensure the progress modal has a minimum height and hidden overflow; ellipsize the status line to prevent scrollbars.
+
+**Why this closes #60**?
+
+- ZIP creation no longer depends on the request lifetime (avoids proxy/Apache timeouts).
+- Temporary files and final ZIP are created on the **same filesystem** (prevents “rename temp file failed” during `ZipArchive::close()`).
+- Users get continuous, truthful feedback for large multi‑GB archives.
+
+Additional **Notes**
+
+- Download tokens are **one‑shot** and are deleted after the GET completes.
+- Temporary artifacts (`META_DIR/ziptmp/.tokens`, `.logs`, and old ZIPs) are cleaned up automatically (≥6h).
+
+---
+
+## Changes 11/5/2025 (v1.8.7)
+
+release(v1.8.7): fix(zip-download): stream clean ZIP response and purge stale temp archives
+
+- FileController::downloadZip
+  - Remove _jsonStart/_jsonEnd and JSON wrappers; send a pure binary ZIP
+  - Close session locks, disable gzip/output buffering, set Content-Length when known
+  - Stream in 1MiB chunks; proper HTTP codes/messages on errors
+  - Unlink the temp ZIP after successful send
+  - Preserves all auth/ACL/ownership checks
+
+- FileModel::createZipArchive
+  - Purge META_DIR/ziptmp/download-*.zip older than 6h before creating a new ZIP
+
+Result: fixes “failed to fetch / load failed” with fetch>blob flow and reduces leftover tmp ZIPs.
+
+---
+
+## Changes 11/4/2025 (v1.8.6)
+
+release(v1.8.6): fix large ZIP downloads + safer extract; close #60
+
+- Zip creation
+  - Write archives to META_DIR/ziptmp (on large/writable disk) instead of system tmp.
+  - Auto-create ziptmp (0775) and verify writability.
+  - Free-space sanity check (~files total +5% +20MB); clearer error on low space.
+  - Normalize/validate folder segments; include only regular files.
+  - set_time_limit(0); use CREATE|OVERWRITE; improved error handling.
+
+- Zip extraction
+  - New: stamp metadata for files in nested subfolders (per-folder metadata.json).
+  - Skip hidden “dot” paths (files/dirs with any segment starting with “.”) by default
+    via SKIP_DOTFILES_ON_EXTRACT=true; only extract allow-listed entries.
+  - Hardenings: zip-slip guard, reject symlinks (external_attributes), zip-bomb limits
+    (MAX_UNZIP_BYTES default 200GiB, MAX_UNZIP_FILES default 20k).
+  - Persist metadata for all touched folders; keep extractedFiles list for top-level names.
+
+Ops note: ensure /var/www/metadata/ziptmp exists & is writable (or mount META_DIR to a large volume).
+
+Closes #60.

+
+## Changes 11/4/2025 (v1.8.3)
+
+release(v1.8.3): feat(mobile+ci): harden Capacitor switcher & make release-on-version robust
+
+- switcher.js: allow running inside Capacitor; remove innerHTML usage; build nodes safely; normalize/strip creds from URLs; add withParam() for ?frapp=1; drop inline handlers; clamp rename length; minor UX polish.
+- CI: cancel superseded runs per ref; checkout triggering commit (workflow_run head_sha); improve APP_VERSION parsing; point tag to checked-out commit; add recent-tag debug.
+
+---
+
+## Changes 11/4/2025 (v1.8.2)
+
+release(v1.8.2): media progress tracking + watched badges; PWA scaffolding; mobile switcher (closes #37)
+
+- **Highlights**
+  - Video: auto-save playback progress and mark “Watched”, with resume-on-open and inline status chips on list/gallery.
+  - Mobile: introduced FileRise Mobile (Capacitor) companion repo + in-app server switcher and PWA bits.
+
+- **Details**
+  - API (new):
+    - POST /api/media/updateProgress.php — persist per-user progress (seconds/duration/completed).
+    - GET  /api/media/getProgress.php — fetch per-file progress.
+    - GET  /api/media/getViewedMap.php — folder map for badges.
+
+- **Frontend (media):**
+  - Video previews now resume from last position, periodically save progress, and mark completed on end, with toasts.
+  - Added status badges (“Watched” / %-complete) in table & gallery; CSS polish for badges.
+  - Badges render during list/gallery refresh; safer filename wrapping for badge injection.
+
+- **Mobile & PWA:**
+  - New in-app server switcher (Capacitor-aware) loaded only in app/standalone contexts.
+  - Service Worker + manifest added (root scope via /public/sw.js; worker body in /js/pwa/sw.js; manifest icons).
+  - main.js conditionally imports the mobile switcher and registers the SW on web origins only.
+
+- **Notes**
+  - Companion repo: **filerise-mobile** (Capacitor app shell) created for iOS/Android distribution.
+  - No breaking changes expected; endpoints are additive.
+
+Closes #37.
+

+
+## Changes 11/3/2025 (V1.8.1)
+
+release(v1.8.1): fix(security,onlyoffice): sanitize DS origin; safe api.js/iframe probes; better UX placeholder
+
+- Add ONLYOFFICE URL sanitizers:
+  - getTrustedDocsOrigin(): enforce http/https, strip creds, normalize to origin
+  - buildOnlyOfficeApiUrl(): construct fixed /web-apps/.../api.js via URL()
+- Probe hardening (addresses CodeQL js/xss-through-dom):
+  - ooProbeScript/ooProbeFrame now use sanitized origins and fixed paths
+  - optional CSP nonce support for injected script
+  - optional iframe sandbox; robust cleanup/timeout handling
+- CSP helper now renders lines based on validated origin (fallback to raw for visibility)
+- Admin UI UX: placeholder switched to HTTPS example (`https://docs.example.com`)
+- Comments added to justify safety to static analyzers
+
+Files: public/js/adminPanel.js

+
+## Changes 11/3/2025 (v1.8.0)
+
+release(v1.8.0): feat(onlyoffice): first-class ONLYOFFICE integration (view/edit), admin UI, API, CSP helpers
+
+Refs #37 — implements ONLYOFFICE integration suggested in the discussion; video progress saving will be tracked separately.
+
+Adds secure, ACL-aware ONLYOFFICE support throughout FileRise:
+
+- **Backend / API**
+  - New OnlyOfficeController with supported extensions (doc/xls/ppt/pdf etc.), status/config endpoints, and signed download flow.
+  - New endpoints:
+    - GET /api/onlyoffice/status.php — reports availability + supported exts.  
+    - GET /api/onlyoffice/config.php — returns DocEditor config (signed URLs, callback).  
+    - GET /api/onlyoffice/signed-download.php — serves signed blobs to DS.  
+  - Effective config/overrides: env/constant wins; supports docsOrigin, publicOrigin, and jwtSecret; status gated on presence of origin+secret.
+  - Public origin resolution (BASE_URL/proxy aware) for absolute URLs.
+
+- **Admin config / UI**
+  - AdminPanel gets a new “ONLYOFFICE” section with Enable toggle, Document Server Origin, masked JWT Secret, and “Replace” control.
+  - Built-in connection tester (status, secret presence, callback ping, api.js load, iframe embed) + CSP helper (Apache & Nginx snippets)
+
+- **Frontend integration**
+  - fileEditor detects OO capability via /api/onlyoffice/status and routes supported types to the DocEditor; loads DocsAPI dynamically.
+  - editFile() short-circuits to openOnlyOffice when applicable; includes live dark/light theme sync where supported.
+  - fileListView pulls status once on load to drive UI decisions (e.g., editing affordances).
+
+- **AdminModel / config**
+  - Adds onlyoffice {enabled, docsOrigin, publicOrigin} defaults and update path, with jwtSecret persisted (kept unless explicitly replaced).
+  - Optional constants in config.php to override and debug.
+
+- **Security & UX notes**
+  - Editor access remains ACL-checked (read/edit) and uses absolute, signed URLs surfaced via controller.  
+  - Admin UI never echoes secrets; “Replace” toggles explicit updates only.  
+  - CSP helper makes it straightforward to permit api.js + iframe + XHR to your DS.  
+
+- **Docs/Styling**
+  - Minor CSS touch-ups around hover states and modal layout.

+## Changes 11/2/2025 (v1.7.5)
+
+release(v1.7.5): CSP hardening, API-backed previews, flicker-free theming, cache tuning & deploy script (closes #50)
+release(v1.7.5): retrigger CI bump (no code changes)
+release(v1.7.5): retrigger CI bump ensure up to date
+
+### Security/headers
+
+- Tighten CSP: pin the inline pre-theme snippet with a script-src SHA-256 and keep everything else on 'self'.
+- Improve cache policy for versioned assets: force 1y + immutable and add s-maxage for CDNs; also avoid HSTS redirects on local/dev hosts.
+
+### Previews & editor
+
+- Remove hardcoded `/uploads/` paths; always build preview URLs via the API (respects UPLOAD_DIR/ACL).
+- Use the API URL for gallery prev/next and file-menu “Preview” to fix 404s on custom storage roots.
+- Editor now probes size safely (HEAD → Range 0-0 fallback) before fetching, then fetches with credentials.
+
+### Login, theming & UX polish
+
+- Pre-theme inline boot sets `dark-mode` + background early; swap to `[hidden]`/`unhide()` instead of inline `display:none`.
+- Add full-screen loading overlay with quick fade and proper color-scheme; prevent white/black flash on theme flips.
+- Refactor app/login reveal flow in `main.js` (`revealAppAndHideOverlay`, `authed` path, setup wizard).
+
+### HTML/CSS & perf
+
+- Make Bootstrap/Styles/Roboto critical (plain `<link rel="stylesheet">`); keep fonts as true preloads; modulepreload app entry.
+- Export a `__CSS_PROMISE__` from `defer-css.js` for sites that still promote preloads.
+- Header logo marked `fetchpriority="high"` for faster first paint.
+- Normalize dark-mode selectors to `.dark-mode` scope (admin panel, etc.).
+
+### Manual Deploy script
+
+- Add `scripts/filerise-deploy.sh`: idempotent rsync-based deploy with writable dirs preserved, optional Composer install, and PHP-FPM/Apache reloads.
+
+### Notes
+
+- If you change the inline pre-theme snippet, update the CSP hash accordingly.
+

+
+## Changes 10/31/2025 (v1.7.4)
+
+release(v1.7.4): login hint replace toast + fix unauth boot
+
+main.js
+
+- Added isDemoHost() and showLoginTip(message).
+- In the unauth branch, call showLoginTip('Please log in to continue').
+- Removed ensureToastReady() + showToast('please_log_in_to_continue') in the unauth path to avoid loading toast/DOM utils before auth.
+
+---
+
+## Changes 10/31/2025 (v1.7.3)
+
+release(v1.7.3): lightweight boot pipeline, dramatically faster first paint, deduped /api writes, sturdier uploads/auth
+
+### 🎃 Highlights (advantages) 👻 🦇
+
+- ⚡ Faster, cleaner boot: a lightweight **main.js** decides auth/setup before painting, avoids flicker, and wires modules exactly once.
+- ♻️ Fewer duplicate actions: **request coalescer** dedupes POST/PUT/PATCH/DELETE to /api/* .
+- ✅ Truthy UX: global **toast bridge** queues early toasts and normalizes misleading “not found/already exists” messages after success.
+- 🔐 Smoother auth: CSRF priming/rotation + **TOTP step-up detection** across JSON & redirect paths; “Welcome back, `user`” toast once per tab.
+- 🌓 Polished UI: **dark-mode persistence with system fallback**, live siteConfig title application, higher-z modals, drag auto-scroll.
+- 🚀 Faster first paint & interactions: defer CodeMirror/Fuse/Resumable, promote preloaded CSS, and coalesce duplicate requests → snappier UI.
+- 🧭 Admin polish: live header title preview, masked OIDC fields with **Replace** flow, and a **read-only Sponsors/Donations** section.
+- 🧱 Safer & cache-smarter: opinionated .htaccess (CSP/HSTS/MIME/compression) + `?v={{APP_QVER}}` for versioned immutable assets.
+
+### Core bootstrap (main.js) overhaul
+
+- Early **toast bridge** (queues until domUtils is ready); expose `window.__FR_TOAST_FILTER__` for centralized rewrites/suppression.
+- **Result guard + request coalescer** wrapping `fetch`:
+  - Dedupes same-origin `/api/*` mutating requests for ~800ms using a stable key (method + path + normalized body).
+  - Tracks “last OK” JSON (`success|status|result=ok`) to suppress false-negative error toasts after success.
+- **Boot orchestrator** with hard guards:
+  - `__FR_FLAGS` (`booted`, `initialized`, `wired.*`, `bootPromise`, `entryStarted`) to prevent double init/leaks.
+  - **No-flicker login**: resolve `checkAuth()` + `setup` before showing UI; show login only when truly unauthenticated.
+  - **Heavy boot** for authed users: load i18n, `appCore.loadCsrfToken/initializeApp`, first file list, then light UI wiring.
+- **Auth flow**:
+  - `primeCsrf()` + `<meta name="csrf-token">` management; persist token in localStorage.
+  - **TOTP** detection via header (`X-TOTP-Required`) & JSON (`totp_required` / `TOTP_REQUIRED`); calls `openTOTPLoginModal()`.
+  - **Welcome toast** once per tab via `sessionStorage.__fr_welcomed`.
+- **UI/UX niceties**:
+  - `applySiteConfig()` updates header title & login method visibility on both login & authed screens.
+  - Dark-mode persistence with system fallback, proper a11y labels/icons.
+  - Create dropdown/menu wiring with capture-phase outside-click + ESC close; modal cancel safeties.
+  - Lift modals above cards (z-index), **drag auto-scroll** near viewport edges.
+  - Dispatch legacy `DOMContentLoaded`/`load` **once** (supports older inline handlers).
+  - Username label refresh for existing `.user-name-label` without injecting new DOM.
+
+### Performance & UX changes
+
+- CSS/first paint:
+  - Preload Bootstrap & app CSS; promote at DOMContentLoaded; keep inline CSS minimal.
+  - Add `width/height/decoding/fetchpriority` to logo to reduce layout shift.
+- Search/editor/uploads:
+  - **fileListView.js**: lazy-load Fuse with instant substring fallback; `warmUpSearch()` hook.
+  - **fileEditor.js**: lazy-load CodeMirror core/theme/modes; start plain then upgrade; guard very large files gracefully.
+  - **upload.js**: lazy-load Resumable; resilient init; background warm-up; smarter addFile/submit; clearer toasts.
+- Toast/UX:
+  - Install early toast bridge; queue & normalize messages; neutral “Done.” when server returns misleading errors after success.
+
+### Correctness: uploads, paths, ACLs
+
+- **UploadController/UploadModel**: normalize folders via `ACL::normalizeFolder(rawurldecode())`; stricter segment checks; consistent base paths; safer metadata writes; proper chunk presence/merge & temp cleanup.
+
+### Auth hardening & resilience
+
+- **auth.js/main.js/appCore.js**: CSRF rotate/retry (JSON then x-www-form-urlencoded fallback); robust login handling; fewer misleading error toasts.
+- **AuthController**: OIDC username fallback to `email` or `sub` when `preferred_username` missing.
+
+### Admin panel
+
+- **adminPanel.js**:
+  - Live header title preview (instant update without reload).
+  - Masked OIDC client fields with **Replace** button; saved-value hints; only send secrets when replacing.
+  - **New “Sponsor / Donations” section (read-only)**:
+    - GitHub Sponsors → `https://github.com/sponsors/error311`
+    - Ko-fi → `https://ko-fi.com/error311`
+    - Includes **Copy** and **Open** buttons; values are fixed.
+- **AdminController**: boolean for `oidc.hasClientId/hasClientSecret` to drive masked inputs.
+
+### Security & caching (.htaccess)
+
+- Consolidated security headers (CSP, CORP, HSTS on HTTPS), MIME types, compression (Brotli/Deflate), TRACE disable.
+- Caching rules:
+  - HTML/version.js: no-cache; unversioned JS/CSS: 1h; unversioned static: 7d; **versioned assets `?v=`: 1y `immutable`**.
+- **config.php**: remove duplicate runtime headers (now via Apache) to avoid proxy/CDN conflicts.
+
+### Upgrade notes
+
+- No schema changes.
+- Ensure Apache modules (`headers`, `rewrite`, `brotli`/`deflate`) are available for the new .htaccess rules (fallbacks included).
+- Versioned assets mean users shouldn’t need a hard refresh; `?v={{APP_QVER}}` busts caches automatically.
+
+---
+
+## Changes 10/29/2025 (v1.7.0 & v1.7.1 & v1.7.2)
+
+release(v1.7.0): asset cache-busting pipeline, public siteConfig cache, JS core split, and caching/security polish
+
+### ✨ Features
+
+- Public, non-sensitive site config cache:
+  - Add `AdminModel::buildPublicSubset()` and `writeSiteConfig()` to write `USERS_DIR/siteConfig.json`.
+  - New endpoint `public/api/siteConfig.php` + `UserController::siteConfig()` to serve the public subset (regenerates if stale).
+  - Frontend now reads `/api/siteConfig.php` (safe subset) instead of `/api/admin/getConfig.php`.
+- Frontend module versioning:
+  - Replace all module imports with `?v={{APP_QVER}}` query param so the release/Docker stamper can pin exact versions.
+  - Add `scripts/stamp-assets.sh` to stamp `?v=` and `{{APP_VER}}/{{APP_QVER}}` in **staging** for ZIP/Docker builds.
+
+### 🧩 Refactors
+
+- Extract shared boot/bootstrap logic into `public/js/appCore.js`:
+  - CSRF helpers (`setCsrfToken`, `getCsrfToken`, `loadCsrfToken`)
+  - `initializeApp()`, `triggerLogout()`
+  - Keep `main.js` lean; wrap global `fetch` once to append/rotate CSRF.
+- Update imports across JS modules to use versioned module URLs.
+
+### 🚀 Performance
+
+- Aggressive, safe caching for versioned assets:
+  - `.htaccess`: `?v=…` ⇒ `Cache-Control: max-age=31536000, immutable`.
+  - Unversioned JS/CSS short cache (1h), other static (7d).
+- Eliminate duplicate `main.js` loads and tighten CodeMirror mode loading.
+
+### 🔒 Security / Hardening
+
+- `.htaccess`:
+  - Conditional HSTS only when HTTPS, add CORP and X-Permitted-Cross-Domain-Policies.
+  - CSP kept strict for modules, workers, blobs.
+- Admin config exposure reduced to a curated subset in `siteConfig.json`.
+
+### 🧪 CI/CD / Release
+
+- **FileRise repo**
+  - `sync-changelog.yml`: keep `public/js/version.js` as source-of-truth only (no repo-wide stamping).
+  - `release-on-version.yml`: build **stamped** ZIP from a staging copy via `scripts/stamp-assets.sh`, verify placeholders removed, attach checksum.
+- **filerise-docker repo**
+  - Read `VERSION`, checkout app to `app/`, run stamper inside build context before `docker buildx`, tag `latest` and `:${VERSION}`.
+
+### 🔧 Defaults
+
+- Sample/admin config defaults now set `disableBasicAuth: true` (safer default). Existing installations keep their current setting.
+
+### 📂 Notable file changes
+
+- `src/models/AdminModel.php` (+public subset +atomic write)
+- `src/controllers/UserController.php` (+siteConfig action)
+- `public/api/siteConfig.php` (new)
+- `public/js/appCore.js` (new), `public/js/main.js` (slim, uses appCore)
+- Many `public/js/*.js` import paths updated to `?v={{APP_QVER}}`
+- `public/.htaccess` (caching & headers)
+- `scripts/stamp-assets.sh` (new)
+
+### ⚠️ Upgrade notes
+
+- Ensure `USERS_DIR` is writable by web server for `siteConfig.json`.
+- Proxies/edge caches: the new `?v=` scheme enables long-lived immutable caching; purge is automatic on version bump.
+- If you previously read admin config directly on the client, it now reads `/api/siteConfig.php`.
+
+### Additional changes/fixes for release
+
+- `release-on-version.yml`
+  - normalize line endings (strip CRLF)
+  - stamp-assets.sh don’t rely on the exec; invoke via bash
+
+release(v1.7.2): harden asset stamping & CI verification
+
+### build(stamper)
+
+- Rewrite scripts/stamp-assets.sh to be repo-agnostic and macOS/Windows friendly:
+  - Drop reliance on git ls-files/mapfile; use find + null-delimited loops
+  - Normalize CRLF to LF for all web assets before stamping
+  - Stamp ?v=<APP_QVER> in HTML/CSS/PHP and {{APP_VER}} everywhere
+  - Normalize any ".mjs|.js?v=..." occurrences inside JS (ESM imports/strings)
+  - Force-write public/js/version.js from VER (source of truth in stamped output)
+  - Print touched counts and fail fast if any {{APP_QVER}}|{{APP_VER}} remain
+
+---
+
+## Changes 10/28/2025 (v1.6.11)
+
+release(v1.6.11) fix(ui/dragAndDrop) restore floating zones toggle click action
+
+Re-add the click handler to toggle `zonesCollapsed` so the header
+“sidebarToggleFloating” button actually expands/collapses the zones
+again. This regressed in v1.6.10 during auth-gating refactor.
+
+Refs: #regression #ux
+
+chore(codeql): move config to repo root for default setup
+
+- Relocate .github/codeql/codeql-config.yml to codeql-config.yml so GitHub default code scanning picks it up
+- Keep paths: public/js, api
+- Keep ignores: public/vendor/**, public/css/vendor/**, public/fonts/**, public/**/*.min.{js,css}, public/**/*.map

+## Quick start: ONLYOFFICE (optional)
+
+FileRise can open & edit office docs using your **self-hosted ONLYOFFICE Document Server**.
+
+**What you need**  
+
+- A reachable ONLYOFFICE Document Server (Community/Enterprise).  
+- A shared **JWT secret** used by FileRise and your Document Server.
+
+**Setup (2–3 minutes)**  
+
+1. In FileRise go to **Admin → ONLYOFFICE** and:
+   - ✅ Enable ONLYOFFICE
+   - 🔗 Set **Document Server Origin** (e.g., `https://docs.example.com`)
+   - 🔑 Enter **JWT Secret** (click “Replace” to set)
+2. (Recommended) Click **Run tests** in the ONLYOFFICE card:
+   - Checks FileRise status, callback reachability, `api.js` load, and iframe embed.
+3. Update your **Content-Security-Policy** to allow the DS origin.  
+   The Admin panel shows a ready-to-copy line for Apache & Nginx. Example:
+
+   **Apache**
+
+   ```apache
+   Header always set Content-Security-Policy "default-src 'self'; base-uri 'self'; frame-ancestors 'self'; object-src 'none'; script-src 'self' 'sha256-ajmGY+5VJOY6+8JHgzCqsqI8w9dCQfAmqIkFesOKItM=' https://your-onlyoffice-server.example.com https://your-onlyoffice-server.example.com/web-apps/apps/api/documents/api.js; style-src 'self' 'unsafe-inline'; img-src 'self' data: blob:; font-src 'self'; connect-src 'self' https://your-onlyoffice-server.example.com; media-src 'self' blob:; worker-src 'self' blob:; form-action 'self'; frame-src 'self' https://your-onlyoffice-server.example.com"
+   ```
+
+   **Nginx**
+
+   ```nginx
+   add_header Content-Security-Policy "default-src 'self'; base-uri 'self'; frame-ancestors 'self'; object-src 'none'; script-src 'self' 'sha256-ajmGY+5VJOY6+8JHgzCqsqI8w9dCQfAmqIkFesOKItM=' https://your-onlyoffice-server.example.com https://your-onlyoffice-server.example.com/web-apps/apps/api/documents/api.js; style-src 'self' 'unsafe-inline'; img-src 'self' data: blob:; font-src 'self'; connect-src 'self' https://your-onlyoffice-server.example.com; media-src 'self' blob:; worker-src 'self' blob:; form-action 'self'; frame-src 'self' https://your-onlyoffice-server.example.com" always;
+   ```
+
+   **Notes**
+   - If your site is https://, your Document Server must also be https:// (or the browser will block it as mixed content).
+   - Editor access respects FileRise ACLs (view/edit/share) exactly like the rest of the app.
+

 ## FAQ / Troubleshooting
 
+- **ONLYOFFICE editor won’t load / blank frame:** Verify CSP allows your DS origin (`script-src`, `frame-src`, `connect-src`) and that the DS is reachable over HTTPS if your site is HTTPS.
+- **“Disabled — check JWT Secret / Origin” in tests:** In **Admin → ONLYOFFICE**, set the Document Server Origin and click “Replace” to save a JWT secret. Then re-run tests.
+
 - **“Upload failed” or large files not uploading:** Ensure `TOTAL_UPLOAD_SIZE` in config and PHP’s `post_max_size` / `upload_max_filesize` are set high enough. For extremely large files, you might need to increase `max_execution_time` or rely on resumable uploads in smaller chunks.
 
 - **How to enable HTTPS?** FileRise doesn’t terminate TLS itself. Run it behind a reverse proxy (Nginx, Caddy, Apache with SSL) or use a companion like nginx-proxy or Caddy in Docker. Set `SECURE="true"` in Docker so FileRise generates HTTPS links.

 ## Dependencies
 
+### ONLYOFFICE integration

+- **We do not bundle ONLYOFFICE.** Admins point FileRise to an existing ONLYOFFICE Docs server and (optionally) set a JWT secret in **Admin > ONLYOFFICE**.
+- **Licensing:** ONLYOFFICE Document Server (Community Edition) is released under the GNU AGPL v3. Enterprise editions are commercially licensed. When you deploy ONLYOFFICE, you are responsible for complying with the license of the edition you use.
