Second-Brain 2.0 (Grundversion) — Runbook

This is the operational quick-reference for the shipped systemd timers/services and the optional FastAPI dashboard backend.

Repository root (on host): /root/.openclaw/workspace

Systemd units (cron jobs)

Unit files are shipped in systemd/ (repo root). Install them into /etc/systemd/system/ (symlink or copy), then reload:

sudo ln -sf /root/.openclaw/workspace/systemd/openclaw-secondbrain-*.service /etc/systemd/system/
sudo ln -sf /root/.openclaw/workspace/systemd/openclaw-secondbrain-*.timer /etc/systemd/system/
sudo ln -sf /root/.openclaw/workspace/systemd/openclaw-memory-archive.* /etc/systemd/system/
sudo systemctl daemon-reload

Enable timers:

sudo systemctl enable --now openclaw-secondbrain-ingest-memory.timer
sudo systemctl enable --now openclaw-secondbrain-index-vectors.timer
sudo systemctl enable --now openclaw-secondbrain-review.timer
sudo systemctl enable --now openclaw-secondbrain-backup.timer
sudo systemctl enable --now openclaw-secondbrain-heartbeat.timer
sudo systemctl enable --now openclaw-secondbrain-proactive-search.timer
sudo systemctl enable --now openclaw-memory-archive.timer

# Optional (Obsidian coupling)
sudo systemctl enable --now openclaw-secondbrain-ingest-obsidian.timer
sudo systemctl enable --now openclaw-secondbrain-export-obsidian.timer

Verify scheduling:

sudo systemctl list-timers --all | grep -E 'openclaw-(secondbrain|memory-archive)' || true

Run a job once:

sudo systemctl start openclaw-secondbrain-ingest-memory.service
sudo systemctl status openclaw-secondbrain-ingest-memory.service --no-pager
sudo journalctl -u openclaw-secondbrain-ingest-memory.service -n 200 --no-pager

Wrapper logs:

tail -n 200 /root/.openclaw/workspace/cron_wrapper.log

FastAPI dashboard (manual start)

FastAPI entrypoint:

cd /root/.openclaw/workspace
python3 -m pip install -r second-brain/requirements-dashboard.txt
SECOND_BRAIN_WORKSPACE="/root/.openclaw/workspace/second-brain" python3 second-brain/fastapi_app.py

Default port is 8501 (same as Streamlit default). Do not run both on the same port.

Endpoint smoke tests:

curl -fsS http://127.0.0.1:8501/api/stats
curl -fsS "http://127.0.0.1:8501/api/engrams?limit=1&offset=0"
curl -fsS "http://127.0.0.1:8501/api/search?q=test&limit=1"

DB quick check

python3 - <<'PY'
import sqlite3
db="/root/.openclaw/workspace/second-brain/data/brain.sqlite"
con=sqlite3.connect(db)
cur=con.cursor()
print(cur.execute("PRAGMA integrity_check").fetchone()[0])
print("engrams:", cur.execute("SELECT COUNT(*) FROM engrams").fetchone()[0])
con.close()
