The Store is Xema's distribution surface for biomes, owned by xema-store-api. Submitting a biome moves it into the store-review execution-environment, where the service validates the manifest, runs contribution checks, and writes a StoreListingVersion row in lifecycle store-submitted. Approval flips it to store-approved; rejection is terminal. The Store is a catalogue you browse and publish to; it does not install. Installation goes through biome lifecycle (plan, review, apply), the same path whether the biome is first-party, third-party, or private to an org. The Store is itself addressable in XVFS at xema://store/biome/<id>. Pricing carries a deferred pricingPolicy field on the listing — present in the schema but not active in this phase. See the Store page for the full publish pipeline and the Publishing SDK page for the publisher-side flow.
