New authentik_group 'T3 Users' (members wizard/emo/ancamilea via data lookups — usernames ARE their emails in this Authentik instance) + a branch in the admin-services-restriction expression policy gating t3.viktorbarzin.me to that group, placed BEFORE the ADMIN_ONLY_HOSTS early-return. Surgical two-step targeted apply (group-with-members first, then the gate) → zero lock-out window. Verified: group has all 3 members, the live policy contains the t3 branch, t3 still 302s to Authentik. Membership is HCL for now (FUTURE: roster-reconciled via the Authentik API).
Note: the authentik stack had 3 unrelated pending drift changes (pgbouncer deployment + 2 tls_secrets) — deliberately NOT applied (targeted apply isolated this change; left for the stack owner).
