Your data is reachable only with your token.
The bearer is the boundary.
Your business is its own Token Holder tenant, and every read or write of your data goes through a bearer scoped to that tenant. The scope is enforced by Token Holder, not by our query layer — which is the part worth caring about, because it means a route of ours that forgot to filter still gets a 403 rather than somebody else's documents. A turn that cannot resolve your session bearer is refused outright instead of falling back to a default token, and that refusal is the tested path, not an incidental one.
Hosting is shared. Business tiers run on the shared Token Holder pool, and rows in the stores KnowMessenger itself owns are keyed to the signed-in account. A dedicated instance — its own store, its own keys, its own boundary — is the enterprise and sovereign tier, and it is mandatory for medical and healthcare deployments at any tier. Dedicated instances are stood up by hand before a customer routes to one; nothing provisions them inline.
The bearer is the scope
Live todayYour data is reached with a token scoped to your tenant, and the wall is Token Holder's to hold. A turn with no bearer is refused, not downgraded.

Shared pool hosting
Live todayBusiness tiers land on the shared Token Holder pool today — one apex, per-tenant scoping. It is the cheaper posture and it is what ships.
Every shared tenant resolves to the same apex
Dedicated instance
Live todayOwn store, own keys, own boundary — the enterprise and sovereign tier, and required for medical and healthcare verticals at any tier. The routing to it is live today; each instance is stood up by hand from a runbook before a customer is routed to it — on request, never self-serve.

Isolation between businesses is enforced by Token Holder and is the strong part. Isolation between members inside one business is not: a shared home is one vault that every member of it can read, and the code says so in as many words. Treat a shared workspace as shared until per-member scoping lands.
