AGPL-3.0 license body confirmed. The LICENSE body sets a default triple license - AGPL-3.0 only, SSPL-1.0 or Elastic License 2.0, at the recipient's choice - so an OSI branch is available for the bulk of the tree, and AGPL-3.0 is the tier this records. It then carves out the x-pack directory as Elastic License 2.0 alone, and that directory is present in the repository. Functionality withheld from the open terms inside the published source is what the ladder calls a gated core, the same shape as litellm's enterprise directory rather than a separate hosted service sold beside a complete core.

  LICENSE.txt states the default is a triple license - GNU Affero General Public License v3.0 only, Server Side Public License v1, and Elastic License 2.0 - and that code licensed solely under the Elastic License 2.0 is found only in the x-pack folder, which is present in the repository root.
