Build the Docker image in GitHub Actions, publish to
ghcr.io/mauricioabh/arbpulse (latest + sha tags), then SSH into the
Hetzner VPS to docker compose pull + up -d with a health-check gate.
The VPS no longer builds images, keeping CPU/RAM free for the running
apps and making rollbacks a matter of pulling a previous sha tag.
- .github/workflows/vps-deploy.yml: build-push (GHCR) + deploy (SSH) jobs
- deploy/docker-compose.yml: app image now ghcr.io/mauricioabh/arbpulse
- deploy/deploy.sh: pulls from GHCR by default (BUILD=1 for local build),
default APP_DIR aligned to /root/projects/arbpulse
- docs: deploy/README.md CI/CD section + paths, README deploy section

Kraken WS v2 book channel does not send deletes for levels evicted from
its top-N window; without client-side truncation those levels lingered
forever as phantom quotes, eventually crossing the local book (bid >= ask)
and feeding the engine a fake permanent arbitrage (~$62.9M bogus P&L).
- BookSide.truncate() removes levels beyond the best depth prices from
the internal map (not just the emitted array)
- KrakenConnector uses depth 10 consistently (subscription + LocalBook)
and truncates both sides after every update
- ExchangeConnector.emit() drops internally crossed books, logs and
forces a resync (book reset + reconnect for a fresh snapshot)
- Unit tests for truncation and the crossed-book guard
- OpenSpec: order-book-integrity spec; change archived (2026-07-19)

Spans are now created and exported to Sentry only when SENTRY_TRACING is enabled (default off), keeping 24/7 operation within the free-tier span quota. Error monitoring stays always-on. Includes OpenSpec change gate-sentry-spans (proposal, design, specs, tasks).
