Sharing Topic Packs

Topic packs can be shared as versioned JSON files. This is separate from the older rule pack export that may appear in full configuration backups.

Exporting/sharing a pack is a Pro feature. (Importing packs is free — see below.)

1. Open Options → Filters → Manage packs (Pack Studio).
2. Select a custom or imported pack.
3. Click Export.
4. Save the .json file.

The file is a xpresspurge-topic-pack envelope (schema version 1). It contains pack metadata and terms only — never feed history, embeddings, anchors, labels, or entitlement data.

Importing is free on every plan.

1. Open Pack Studio → Import.
2. Choose a file or paste JSON.
3. Review the preview (name, polarity, term count, collision warnings).
4. Confirm Import pack.

Imported packs are not activated automatically. Turn them on from the Topic Packs card when you are ready. Activating imported packs is free and unlimited — like the built-in kits, imported packs have no active-count limit.

If a pack id collides with a built-in or an existing custom pack, import renames the id safely. Editing an imported pack keeps it local; Pro users can treat it as a fork on this device.

Full Options export/import may still include sharedPacks as rule bundles. Those are not topic packs. Prefer the Pack Studio envelope when sharing topic lexicons.

Portable URL encoding exists for small packs, with a size guard. Hosted xpresspurge.com/p/<slug> pages and extension deep-link import are planned separately from this release.
