2. GNU Affero General Public License v3.0 or later (AGPL-3.0-or-later)
================================================================================

Everything else Epicenter ships is licensed under AGPL-3.0-or-later. The
full text is in licenses/LICENSE-AGPL-3.0. This covers all shipped apps and the
Epicenter-internal packages.

You're free to run, modify, and self-host any of these. If you distribute
a modified version, you share the changes back with the community.

For hosted infrastructure (apps/api, apps/self-host), AGPL
§13 extends this to network use: running a modified version as a service
counts as distribution.

For consumer apps that run locally on a user's machine, §13 does not
trigger, but the underlying GPL distribution clause still applies: anyone
who forks and distributes a modified binary shares the changes back.

3. Proprietary (deferred tier, currently empty)
================================================================================

No components are currently licensed under proprietary terms, and none are
planned. Revenue comes from hosting (Epicenter Cloud), not licensing.

This tier is documented as an escape hatch for one specific situation: a
paying customer requires a specific feature that AGPL self-hosting would
otherwise give away free. It will not be populated speculatively. The
empty-tier end-state is the goal.

If this tier is ever populated, modules will live in clearly delineated
subdirectories with their own LICENSE files declaring "All rights reserved"
terms, and will be listed here.

See docs/licensing/licensing-strategy.md for the conventions.

================================================================================

If a package's per-package LICENSE file or package.json "license" field
ever conflicts with this index, the per-package files are authoritative.
This index will be updated to match.
