# References and identity

> Use the right workflow and node reference for people, local state, and safe retries.

Droyd uses several kinds of references because they serve different jobs.
Workflow and node UUIDs are durable record identities; readable keys make a
project easier to recognize; client keys make a mutation safe to retry.

`latest` and `best` resolve remote workflow state. `current` is a local pointer
in your workspace and can change as you move between experiments. Do not treat
`current` as a portable name for a remote node.

Save returned IDs in the managed lock file and use client keys for operations
that may be retried after a network interruption.
