# lasuite-drive — INSTALL-TIME OIDC wiring hook (Phase 2 Q3.2a;
# plan-lasuite-drive-oidc-robustness.md Part A).
#
# Runs during the install tier AFTER `abra app new` + EXTRA_ENV + `abra app secret generate`, and
# BEFORE the single `abra app deploy` (runner/harness/lifecycle.py::_run_install_steps). By writing
# the OIDC env + the real client secret into the app's `.env` HERE, the recipe deploys ONCE with
# OIDC already wired — eliminating the flaky post-deploy in-place `--force --chaos` 12-service
# reconverge that the old setup_custom_tests.sh did (collabora WOPI-discovery race; see JOURNAL
# Step 0). The orchestrator provisions the per-run realm/client on the live-warm keycloak BEFORE
# this hook and writes $CCCI_DEPS_FILE (the recipe→creds dict).
#
# Env supplied by the harness:
#   CCCI_APP_DOMAIN — the per-run lasuite-drive app domain
#   CCCI_APP_ENV    — path to the app's .env (the one `abra app deploy` reads)
#   CCCI_RECIPE     — "lasuite-drive"
#   CCCI_DEPS_FILE  — JSON {keycloak: {domain, realm, client_id, client_secret, ...}} (may be empty)
