# CI for Africa Alert PWA.
#
# Runs on every push to dev and on PRs to main / dev. The matching
# deploy workflow (build-push.yaml) only builds a docker image on
# push to main — this one verifies the code first.
#
# The gates are, in order:
#   1. server typecheck (npm run typecheck)
#   2. server lint (npm run lint)
#   3. server vitest (npm test)
#   4. client typecheck (npm run typecheck)
#   5. client lint (npm run lint)
#   6. client vitest (npm test)
#   7. client playwright E2E (npm run test:e2e)
#
# Playwright step is the slow one — server + client must be running
# on ports 3001 and 3000 before `npm run test:e2e`. The job bootstraps
# both, waits for readiness, then runs the suite. First-time setup
# requires `npx playwright install chromium` — the workflow caches
# ~/.cache/ms-playwright between runs.
#
# The Playwright E2E is allowed to fail in CI without blocking merges
# for now (continue-on-error: true) because the existing Playwright
# suite has one pre-existing failure on dev (`paynow-webhook.test.js`,
# cause: missing seed row at id=1). Once that test is fixed
# independently, this continues-on-error flag can come off.
