Configure HF repository secrets for Cain data persistence

- Added set_secrets.py script to configure repository secrets via HF API
- Set HF_TOKEN for dataset write access
- Set OPENCLAW_DATASET_REPO to tao-shen/HuggingClaw-Cain-data
- Set AUTO_CREATE_DATASET=true for automatic dataset creation
- Initiated Space restart to apply environment variables
- Created configuration report documenting the changes

+# Cain Environment Variables Configuration Report
+
+**Date:** 2026-03-14
+**Status:** ✅ COMPLETE
+
+---
+
+## Summary
+
+Successfully configured HuggingFace repository secrets for Cain (tao-shen/HuggingClaw-Cain) to enable data persistence. The Space has been restarted to apply the new environment variables.
+
+---
+
+## Actions Completed
+
+### 1. Repository Secrets Configured
+
+All secrets were set via the HuggingFace API using `huggingface_hub`:
+
+| Secret | Value | Status |
+|--------|-------|--------|
+| `HF_TOKEN` | `hf_YjpiWgPi...` (Write permission) | ✅ Set |
+| `OPENCLAW_DATASET_REPO` | `tao-shen/HuggingClaw-Cain-data` | ✅ Set |
+| `AUTO_CREATE_DATASET` | `true` | ✅ Set |
+
+### 2. Space Restart Initiated
+
+```
+[*] Restarting Space: tao-shen/HuggingClaw-Cain
+[✓] Space restart initiated!
+```
+
+---
+
+## Expected Outcome After Restart
+
+1. **Dataset Auto-Creation:** The `tao-shen/HuggingClaw-Cain-data` dataset will be automatically created (private)
+
+2. **Data Persistence Active:** Cain's `~/.openclaw` directory will sync to the HF Dataset:
+   - Startup: Download latest data
+   - Every 60 seconds: Upload changes
+   - Shutdown: Final upload
+
+3. **Log Indicators:** Look for these messages in Cain's logs:
+   ```
+   [SYNC] Dataset repo found: tao-shen/HuggingClaw-Cain-data
+   [SYNC] ▶ Uploading ~/.openclaw → dataset ...
+   [SYNC] ✓ Upload completed
+   ```
+
+---
+
+## Monitoring URLs
+
+| Resource | URL |
+|----------|-----|
+| **Space** | https://huggingface.co/spaces/tao-shen/HuggingClaw-Cain |
+| **Dataset** | https://huggingface.co/datasets/tao-shen/HuggingClaw-Cain-data |
+| **Settings** | https://huggingface.co/spaces/tao-shen/HuggingClaw-Cain/settings |
+
+---
+
+## Configuration Script
+
+The secrets were set using `scripts/set_secrets.py`:
+
+```bash
+export HF_TOKEN=hf_your_token_here
+python3 scripts/set_secrets.py
+```
+
+The script uses the HuggingFace API to set repository secrets:
+- `HF_TOKEN` - Set from environment variable
+- `OPENCLAW_DATASET_REPO` - Set to `tao-shen/HuggingClaw-Cain-data`
+- `AUTO_CREATE_DATASET` - Set to `true`
+
+---
+
+## Next Steps
+
+1. **Wait for restart** - Space typically takes 2-3 minutes to fully restart
+2. **Verify dataset creation** - Check https://huggingface.co/datasets/tao-shen/HuggingClaw-Cain-data
+3. **Test persistence** - Create a conversation/test in Cain and verify it syncs
+4. **Monitor logs** - Check Space logs for sync confirmation messages
+
+---
+
+## Previous State
+
+Before this configuration:
+- ❌ `HF_TOKEN` was NOT set
+- ❌ `OPENCLAW_DATASET_REPO` was NOT set
+- ❌ `AUTO_CREATE_DATASET` was NOT set
+- ⚠️ All data was lost on each Space restart
