Link-native durability

Workspaces

Saved compare views and follows stay portable as explicit bundle links. Reopening state should land on the same canonical compare or artifact URL, not a reconstructed local approximation.
Mode · bundle-first portability
Scope · saved compare views + follows
State · href-native reopening

Workspace bundle

Portable bundles stay link-native. Use them to preview a shared workspace, reopen the same compare URLs on another device, or import the snapshot without reconstructing intent from loose local fields.

Preview or import a shared bundle

How it works

  • Copy a portable bundle link from the current device or workspace snapshot.
  • Open that URL anywhere to preview the exact saved compare and follow hrefs.
  • Import the bundle locally when you want the same workspaces and follows on that device.
