Validation limits: the native fixture host has the packaged low-address workaround active, and the production build zone also rejects high-address mappings. A successful low-address run is regression coverage; the reported high-address startup case still needs tester acceptance.

Package: pkg://openindiana.org/web/browser/firefox@158.0.1,5.11-2026.0.0.1:20261024T164848Z

Please report package/kernel versions, the live _userlimit, relevant setting lines, startup behavior and the smoke-page result on the PR. Keep cores and profile data private.
