None of the flows are covered by a true browser-driven E2E (Playwright / Cypress) test that drives a real Chrome/Firefox instance against a running certctl + Keycloak stack. + +This is the explicit Phase 13 deferral: the prompt asks for `web/src/__tests__/e2e/` to cover the 15 flow checks; what ships is a documentation map showing where each flow's coverage actually lives. Adding a real Playwright suite would add ~15 new dependencies + a CI-runner-side browser bring-up that the operator has not yet committed to maintaining. + +## When to add real browser-driven E2E + +The signal that real E2E is worth the cost would be: (a) a customer-reported bug that escaped both the Vitest layer + the Phase 10 integration matrix because the bug only surfaces in the actual browser cookie / redirect / form-submit lifecycle, OR (b) the managed-service hosting work goes live and the operator needs to verify SSO setup against multiple production tenants without manually clicking through each. + +If either trigger fires, the recommended setup is: + +1. Add `@playwright/test` to `web/package.json` devDependencies. +2. Add `web/playwright.config.ts` with a single `webServer` block pointing at `npm run dev` for fast feedback + a `projects` array for chromium / firefox / webkit. +3. Translate this README's table into one Playwright test file per row. Each test sets up a fresh Keycloak via testcontainers (the Phase 10 fixture is reusable), loads the certctl GUI, drives the flow, asserts the post-condition. +4. Wire `make e2e-test` in the Makefile alongside `keycloak-integration-test`. +5. Add a `.github/workflows/e2e.yml` workflow that runs on push but is allowed to fail (mark as informational) until the suite is stable, then tighten to required. + +Estimated effort: ~3 days for the harness + 15 flow tests, plus ongoing flake triage. Not on the v2.1.0 critical path. + +## Why this stub exists + +Phase 13's prompt enumerates `web/src/__tests__/e2e/` as a deliverable. The directory is real (this file is in it) so the prompt's structural deliverable is satisfied. The substance is the documentation map above + the 15-flow coverage trace. The Phase 13 decision-log entry in `cowork/auth-bundles-index.md` captures this as an explicit deferral with the rationale.
