name: Enterprise E2E (Playwright)

# Enterprise Playwright suite — exercises premium-key gated features (audit,
# teams, analytics) plus full OAuth + SAML logins via the Keycloak compose
# stacks under testing/compose. Slow and secret-gated, so it runs in four
# situations:
#
#   - PRs that touch proprietary / premium / SSO compose / enterprise tests
#     (driven by build.yml via workflow_call, path-filtered against
#     .github/config/.files.yaml `proprietary`),
#   - every push to main (post-merge safety net),
#   - on a nightly cron schedule (catches Keycloak image drift, license
#     expiry, upstream proprietary changes),
#   - manual workflow_dispatch.

on:
  workflow_call:
  push:
    branches: ["main"]
  schedule:
    - cron: "0 4 * * *"
  workflow_dispatch:

# No `concurrency:` block here on purpose. When this workflow is called via
# workflow_call from build.yml, ${{ github.workflow }}/event_name/pr_number
# resolve to the *caller's* values, producing the same group key as build.yml
# and causing the workflow_call instantiation to self-cancel — the job
# silently fails to spawn while `${{ needs.X.result }}` still reports
# `failure`. Standalone runs (push-to-main, nightly cron, dispatch) don't
# overlap often enough to need explicit concurrency control.
