Rounds out the tenant_memberships operator flags added earlier this
phase (-create-tenant/-grant-membership-*): grant had no way to undo
itself, and there was no way to see who was actually in a tenant
without querying Postgres directly.
rbacstore.RevokeMembership deletes a tenant_memberships row, but
refuses to revoke a tenant's current Owner -- Owner is also a
dedicated tenants.owner_user_id column (SetOwner), so deleting that
membership without transferring ownership first would leave
owner_user_id pointing at a user with no membership in the tenant at
all. Ownership transfer is a deliberate, separate action per the RBAC
matrix ("Transfer tenant Owner -- Owner only"), not a side effect of
revoking access.
rbacstore.ListMembershipsForTenant is ListMembershipsForUser's
inverse -- joined with users so the result is actually useful (email,
display name), not just a bare user ID list.
enterprise-auth gains -revoke-membership-tenant/
-revoke-membership-user-email (both required together, same shape as
-grant-membership-*) and -list-memberships-tenant (prints tab-separated
id/email/display-name/role to stdout and exits -- an operator
convenience, not a machine-readable API; this binary deliberately has
no admin HTTP surface, per its own doc comment on why). Changing a
role is unchanged: re-run -grant-membership-* with a different
-grant-membership-role, SetMembership's upsert already handles it.
Covered by five new skip-gated integration tests in rbacstore_test.go
(RBACSTORE_TEST_POSTGRES_ADDR), including the Owner-revocation refusal
and cross-tenant leak check for ListMembershipsForTenant -- not run
against a live database in this environment, same disclosed gap as the
rest of this phase's Postgres-backed work. Docs updated:
phase-4-runbook.md's known-gaps bullet, enterprise/README.md's
bootstrap walkthrough and package layout table.
