Category	Suggestion	Impact
General	Validate and cache the login session cy.session() by default clears cookies between tests, which may drop the security_authentication cookie needed by the proxy. Pass a validate function and/or cacheAcrossSpecs: true to ensure the session (including the auth cookie) is restored reliably before each test. cypress/support/index.js [66-72] if (Cypress.env('ENDPOINT_WITH_PROXY')) { beforeEach(() => { - cy.session('security_authentication', () => { - cy.login(); - }); + cy.session( + 'security_authentication', + () => { + cy.login(); + }, + { + cacheAcrossSpecs: true, + validate() { + cy.getCookie('security_authentication').should('exist'); + }, + } + ); }); } Suggestion importance[1-10]: 7 __ Why: Adding a validate function and cacheAcrossSpecs: true to cy.session() is a reasonable improvement to ensure the auth cookie is reliably restored across tests and specs, which is relevant given the removal of Cypress.Cookies.preserveOnce(). This addresses potential session reliability issues.	Medium
