- Add SecurityOptionsValidator (IValidateOptions<SecurityOptions>) enforcing RoleRefreshThresholdMinutes < IdleTimeoutMinutes; registered with ValidateOnStart in AddSecurity — startup FAILS if threshold >= idle, so the invariant cannot be silently misconfigured away. - Update SecurityOptions XML-docs: class-level summary distinguishes JWT Bearer path (JwtSigningKey/JwtExpiryMinutes) from Blazor cookie session path (IdleTimeoutMinutes/ RoleRefreshThresholdMinutes); both time fields document the ~45-min effective idle window and the new cross-field constraint. - Remove dead jwtService variable from /auth/login lambda in AuthEndpoints.cs (resolved but never used since login moved to SessionClaimBuilder). - Extract ApplyValidationResultAsync helper from OnValidatePrincipalAsync (pure decision-application step); add 3 adapter tests covering Reject → RejectPrincipal + SignOutAsync; Replace → ReplacePrincipal + ShouldRenew; Keep → no-op. - Fix inaccurate TryRefreshAsync comment (dropped "OR last-activity needs advancing" — the code only returns non-null when roleRefreshDue). - Add InternalsVisibleTo for Security.Tests in Security.csproj. - Add IsRoleRefreshDue tests: missing claim → due; unparsable claim → due; plus integration test covering the full ValidateAsync path for a principal missing zb:lastrolerefresh (triggers refresh + re-stamps anchor rather than keeping stale principal forever). - Add SecurityOptionsValidatorConfigGuardTests: default succeeds; equal fails; greater fails; boundary (idle-1) succeeds; wiring confirmed via AddSecurity container.
