+# CS26 — Computer-Science Dataset + Portal
+
+This repo contains:
+
+- **A Hugging Face Dataset**: `CS26/Computer-Science`
+- **A Hugging Face Space (portal)**: `CS26/cs26-portal` (Gradio)
+
+The portal is live at:
+
+- Direct app URL: `https://cs26-cs26-portal.hf.space/`
+- Space page: `https://huggingface.co/spaces/CS26/cs26-portal`
+
+## Authentication (no tokens in repos)
+
+Do **not** hardcode any `hf_...` tokens in code or commit them to git.
+
+Use the Hugging Face CLI to store your token **locally**:
+
+```powershell
+hf auth login --force
+hf auth whoami
+```
+
+This stores credentials in your user profile cache and lets `huggingface_hub` authenticate automatically.
+
+## Portal (Space) — `cs26-portal/app.py`
+
+Features:
+
+- **RTL + Hebrew UI** (including mixed Hebrew / Latin in search headings)
+- Folder navigation with breadcrumbs
+- **Stateful refresh and deep links**: current folder is stored in the **`?path=`** query string (URL-encoded), with **`#`** kept in sync for refresh-friendly navigation, plus a **`localStorage`** copy for resilience
+- Search within current folder subtree
+- File actions on click:
+  - **PDF**: downloads immediately
+  - **ZIP/archives**: download immediately
+  - **Office (doc/docx/ppt/pptx)**: opens OfficeApps viewer in a **new tab**, and shows a preview pane with “הורדה” + “תצוגה (Office)”
+  - **Images**: in-page preview + download link
+  - **Text/code (txt/c/...)**: in-page preview + download link
+- **Prepare Folder ZIP**: builds a ZIP from the dataset via `snapshot_download` / temp zip; status and errors are shown in a **status** markdown area next to the download widget
+- **Direct Hugging Face downloads**: filenames with Hebrew (or other non-ASCII) may still appear percent-encoded in some browsers when downloading straight from `huggingface.co` URLs; the app uses best-effort `<a download>` where applicable
+
+### Deploy the Space
+
+From repo root:
+
+```powershell
+python .\upload_space.py
+```
+
+### Troubleshooting
+
+- **Search shows nothing**: search is scoped to the **current folder subtree**; navigate into a year or topic folder first, or clear the search box and use **רענון** after changing folders.
+- **ZIP errors or long waits**: large folders download many files from Hugging Face first; watch the status markdown under the ZIP button for progress or a Python traceback if something fails.
+- **Blank preview for images**: raster previews are embedded as data URIs when needed; if something still fails, use the dataset **resolve** link from the preview panel.
+
+## Dataset uploader — `upload_to_hf.py`
+
+Uploads the local folder to the dataset repo **in batches of 10 files** with retry/resume.
+
+It excludes:
+
+- `.git/**`
+- `cs26-portal/**`
+- `upload_to_hf.py`, `upload_space.py`
+
+Run:
+
+```powershell
+python .\upload_to_hf.py
+```
+
+Optional environment variables:
+
+- `HF_REPO_ID` (default `CS26/Computer-Science`)
+- `HF_LOCAL_FOLDER` (default `c:\GitRepos\Computer-Science`)
+- `HF_BATCH_SIZE` (default `10`)
+- `HF_RETRY_SLEEP_SECONDS` (default `5`)
+
+## Rollback safety
+
+Local repo has:
+
+- tag: `backup-before-portal-fixes`
+- branch: `backup/current-state`
+
+Space repo has:
+
+- tag: `backup-before-portal-fixes`
+- branch: `backup/current-state`
+- tag: `latest` pointing at current `main` HEAD
