novolis-workspaces design · novolis-workspaces

Three libraries, one repo

Library	Owns	Must not know
Novolis.Snapshots	Serialize state, snapshot refs	Timeline, workspace manifests
Novolis.Timeline	Graph over snapshot refs	Files, zip, workspace layout
Novolis.Workspaces	Workspace/project structure	Branching graph internals

Adapters (Workspaces.Snapshots, Workspaces.Timeline, Workspaces.Projects.Timeline) compose all three.

On-disk workspace layout

my-workspace/
  .novolis/
    workspace.json
    settings.json
    timeline/          # branch/head/nodes (Timeline.FileSystem)
    snapshots/         # zip blobs (Workspaces.Snapshots)
  projects/
    {folder}/
      project.json
      documents/
      assets/
      outputs/
      cache/
      temp/

Restore rules

Create a safety save point before restore.
Restore working files from the selected zip snapshot.
Preserve .novolis/timeline/ (history is not rolled back with working tree).

Naming (user-facing)

Use: Save Point, Restore Point, Timeline, Branch, Current.

Avoid: Commit, Checkout, Repository, Merge, Rebase.

Platform boundaries

Existing	Relationship
`Novolis.IO.Workspace.IWorkspace`	Mandatory typed directory-root contract composed by `IProjectWorkspace`
`Novolis.Workspaces.DotNet.*`	Physical solution topology, explicit MSBuild evaluation, and portable Roslyn facts
`ISnapshotCapableEventStore`	Stream compaction — unrelated
`SimulationTimeline<TState>`	Tick replay — unrelated

Filesystem

All disk facets use System.IO.Abstractions (IFileSystem) for testability.
