RBAC Is the Path, Not the Permission Count
Published August 24, 2026
A large permission catalog means little if one route, tool, data query, or approval path can bypass it.
<h2>Permission lists are only inventory</h2><p>The security property comes from enforcement: route middleware, policies, data scope, ownership checks, approval boundaries, and denial tests.</p><h2>Test the negative path</h2><p>It is easy to prove an admin can perform an action. The useful regression test proves the wrong role, wrong tenant, wrong project, or wrong record cannot.</p><h2>AI and integrations must use the same model</h2><p>Adding a new tool or provider adapter should not create a second shortcut around authorization. Every entry point needs the same capability and scope model.</p><h2>Measure coverage, not impressiveness</h2><p>The relevant question is not how many permissions exist; it is whether every sensitive execution path is covered by the intended policy.</p>
