# lasuite-docs — INSTALL-TIME OIDC wiring hook (rcust P2b; migrated from the deleted
# setup_custom_tests.sh post-deploy path — sibling of lasuite-drive/-meet's hooks).
#
# Runs during the install tier AFTER `abra app new` + EXTRA_ENV + `abra app secret generate`, and
# BEFORE the single `abra app deploy` (lifecycle.py::_run_install_steps). Writing OIDC env + the
# real client secret HERE means the recipe deploys ONCE with OIDC already wired — no post-deploy
# reconverge. 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). docs' OIDC settings are
# config-only (validated by `manage.py check`, not fetched at boot), so the stack boots healthy
# with the env set. Env names per lasuite-docs's .env.sample (same values the old post-deploy
# hook wrote — byte-identical wiring, only the timing moved).
#
# Env supplied by the harness:
#   CCCI_APP_DOMAIN — the per-run lasuite-docs app domain
#   CCCI_APP_ENV    — path to the app's .env (the one `abra app deploy` reads)
#   CCCI_DEPS_FILE  — JSON {keycloak: {domain, realm, client_id, client_secret, ...}} (may be empty)
