Assets nest parent to child — a plant, a line and a single pump live in one tree, with a built-in guard against circular hierarchies. Expanding an asset on the management page shows its recurring tasks with type, interval, last completion and next due date. A live wildcard filter searches across name, category, location and owner, and a previewed CSV import turns an existing equipment list into a populated system in one upload.

Three roles carry progressive privileges: workers read and mark tasks done, team leaders edit assets, tasks and parts and run imports, management adds user administration and mail configuration. The UI shows each role only its own buttons — but authorization is enforced independently in the REST API on every request, so a hidden button cannot be reached by crafting a URL. Accounts are invite-only, sessions use signed JWTs, passwords are bcrypt-hashed, and an audit log records who changed what.

A short walkthrough of the live demo: dashboard, asset management, task completion, logs. Self-hosted video — no external player, no tracking.
