Module Types 

Value types for the update lifecycle: channels, status, installation states, update manifests, platform metadata, and telemetry records.

These structs are shared between UpdateManager methods, IPC handlers (Mountain ↔ Air), and the test suite. Keeping them in one file makes the shape of the update domain legible without reading the 2600-line implementation.

Structs

Platform-specific fields inside an UpdateInfo.

RollbackState

Snapshot of a rollback point created before applying an update.

UpdateInfo

Manifest returned by the update server for an available release.

UpdateStatus

Live status snapshot surfaced to Mountain and IPC callers.

UpdateTelemetry

Analytics record emitted after every update operation.

Enums

Fine-grained installation lifecycle state.

PackageFormat

Supported OS package formats.

UpdateChannel

Update distribution channel.
