# Cross‑Workspace Experience – Project artveris

In project `artveris` (project ID `d44c219a-0b31-4de1-b160-323eb34a4c6a`) a recurring issue was identified where `deploy.py` could inadvertently launch two parallel SSH deployments, causing log overwrite and database migration conflicts.

## Resolution
Implemented a file‑based locking mechanism using `flock -n`. The script now checks for an existing lock when a deployment starts and exits immediately if the lock is already held, preventing duplicate runs.
