# `Hephaestus.Instances.Tracker`
[🔗](https://github.com/hephaestus-org/hephaestus_core/blob/v0.3.1/lib/hephaestus/instances/tracker.ex#L1)

A GenServer that registers its parent Hephaestus module in the
`Hephaestus.Instances` registry on boot.

Started as a child of each `use Hephaestus` supervision tree.
When the tracker process dies (shutdown, crash), the Registry
automatically deregisters the module — no explicit cleanup needed.

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.
