+# Cain Memory Persistence Fix Report
+
+**Date:** 2026-03-14
+**Space ID:** tao-shen/HuggingClaw-Cain
+**Dataset ID:** tao-shen/HuggingClaw-Cain-data
+**Status:** ✅ CONFIGURATION COMPLETE - AWAITING SPACE STARTUP
+
+---
+
+## Executive Summary
+
+Cain's memory persistence was **DISABLED** due to missing critical environment variables. The required variables have now been **SET** and the Space has been **RESTARTED** to apply the changes.
+
+---
+
+## Changes Made
+
+### 1. Repository Secrets Set ✅
+
+| Secret | Value | Status |
+|--------|-------|--------|
+| `HF_TOKEN` | `hf_***...***` (valid write token) | ✅ SET |
+| `AUTO_CREATE_DATASET` | `true` | ✅ SET |
+
+**Set via:** HuggingFace Python API
+**Method:** `api.add_space_secret()`
+
+### 2. Space Restart ✅
+
+The Space was restarted to apply the new environment variables.
+
+- **Action:** Restart initiated via HuggingFace API
+- **Status:** Space is currently starting up (`RUNNING_APP_STARTING`)
+- **Expected uptime:** 2-3 minutes
+
+---
+
+## Verification Results
+
+### Dataset Status ✅
+- **Dataset exists:** `tao-shen/HuggingClaw-Cain-data`
+- **Files present:** .openclaw, config-backup, memory, space_code_backup, and more
+- **Visibility:** Public (based on dataset info)
+
+### Configuration Status ✅
+| Component | Status |
+|-----------|--------|
+| HF_TOKEN secret | ✅ SET |
+| AUTO_CREATE_DATASET secret | ✅ SET |
+| Dataset repository | ✅ EXISTS |
+| Space status | ⏳ STARTING |
+| Memory persistence | ⏳ WILL BE ACTIVE AFTER STARTUP |
+
+---
+
+## Expected Behavior After Startup
+
+Once the Space fully starts, you should see these log messages:
+
+```
+[SYNC] OPENCLAW_DATASET_REPO not set — auto-derived from SPACE_ID: tao-shen/HuggingClaw-Cain-data
+[SYNC] Dataset repo found: tao-shen/HuggingClaw-Cain-data
+[SYNC] ▶ Restoring ~/.openclaw from dataset tao-shen/HuggingClaw-Cain-data ...
+[SYNC] ✓ Restore completed.
+```
+
+Then periodically:
+```
+[SYNC] ▶ Uploading ~/.openclaw → dataset ...
+[SYNC] ✓ Upload completed at 2026-03-14T...
+```

+## Files Created During Fix
+
+| File | Purpose |
+|------|---------|
+| `set_hf_secrets.py` | Script to set repository secrets via HF API |
+| `restart_space.py` | Script to restart the Space via HF API |
+| `verify_persistence.py` | Script to verify persistence is working |
+| `check_sync_logs.py` | Script to check Space logs for sync status |
+| `PERSISTENCE_FIX_REPORT.md` | This report |
+

+
+## What This Fixes
+
+Before this fix:
+- ❌ All conversations lost on Space restart
+- ❌ All settings lost on Space restart
+- ❌ All credentials lost on Space restart
+- ❌ Agent memory not persisted
+
+After this fix:
+- ✅ Conversations persisted to HuggingFace Dataset
+- ✅ Settings persisted
+- ✅ Credentials persisted
+- ✅ Agent memory persisted
+- ✅ Automatic sync every 60 seconds
+
+---
+
+## Technical Details
+
+### Environment Variables Configured
+
+1. **HF_TOKEN** - HuggingFace API token with write permissions
+   - Allows the Space to authenticate with HuggingFace
+   - Required for creating/accessing the dataset
+   - Required for uploading/downloading files
+
+2. **AUTO_CREATE_DATASET=true** - Enables automatic dataset creation
+   - If dataset doesn't exist, creates it automatically on first startup
+   - Creates a private dataset by default
+   - Auto-derived from SPACE_ID as `{SPACE_ID}-data`
+
+### Sync Behavior
+
+- **Startup:** Download `.openclaw` directory from dataset
+- **Every 60 seconds:** Upload only changed files (hash-based)
+- **Shutdown:** Final upload before Space stops
+
+---
+
+## Troubleshooting
+
+If persistence is not working after startup:
+
+1. **Check logs for:** `[SYNC] WARNING: HF_TOKEN not set`
+   - If seen, the secret wasn't applied correctly
+
+2. **Check logs for:** `[SYNC] Dataset repo NOT found`
+   - If seen with no creation message, `AUTO_CREATE_DATASET` may not be set
+
+3. **Manual verification:**
+   - Visit: https://huggingface.co/datasets/tao-shen/HuggingClaw-Cain-data
+   - Check if `.openclaw/` folder exists with recent files
+
+4. **Manual restart:**
+   - Visit: https://huggingface.co/spaces/tao-shen/HuggingClaw-Cain/settings
+   - Click "Restart" or "Factory reset and reboot"
+
+---
+
+## Next Steps
+
+1. Wait 2-3 minutes for the Space to fully start
+2. Monitor logs for sync messages
+3. Verify dataset has recent file updates
+4. Test persistence by making a change and checking if it appears in the dataset

+**Configuration Status:** ✅ COMPLETE
+**Waiting for:** Space startup and sync verification
