# L0 STATIC — Keycloak client secrets are declared consistently, ordered by a REAL
# Flux edge, and healed by a reconciler whose behaviour is proven offline
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
#
# R-IDP-03 (identity config is declarative) and R-IDP-04 (IdP secrets SOPS-encrypted)
# are both implemented through ONE mechanism that FAILS OPEN: the KeycloakRealmImport
# resolves each client's secret from a `(env:NAME)` placeholder mapped to a key of the
# SOPS-encrypted keycloak-realm-clients Secret. When the operator cannot resolve a
# placeholder it stores the LITERAL placeholder text as the client secret AND THE IMPORT
# JOB STILL REPORTS SUCCESS — then rests at Done=True / Started=False and never re-runs.
#
# Measured 2026-09-06: prod had all 12 clients holding the literal placeholder (every
# OIDC login failed with "Invalid client or Invalid client credentials"); dev had exactly
# one (oauth2-proxy), because that Secret key was added AFTER dev's import completed.
# Declarative config that silently does not apply is not declarative config.
#
# GIVEN the repository as authored,
# THEN  every confidential client declares a placeholder, every placeholder is defined,
#       resolves to the keycloak-realm-clients Secret, and names a key that EXISTS in the
#       SOPS file under the `<clientId>-client-secret` contract the reconciler derives
#       from; public clients declare no secret; the Flux Kustomization applying the Secret
#       is a transitive `dependsOn` ancestor (wait: true) of the ones applying the import
#       and the reconciler — a real edge, not a comment; the reconciler is reconciled from
#       BOTH cluster entrypoints, mounts only what it needs, carries no ServiceAccount
#       token and contains no dollar sign; and its own `--selftest` (extracted from the
#       shipped ConfigMap and executed) proves compare-then-write, idempotence,
#       no-secret-logging, the endpoint allow-list and fail-closed behaviour.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git + PyYAML +
# stdlib); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this Chainsaw
# Test wraps the SAME script.
#
# NOT proven here: that the LIVE realm's stored secrets match git (that is
# tests/l2-behavioral/keycloak-client-secrets-match-git), that the SOPS ciphertext
# decrypts to a usable value (key PRESENCE is offline-checkable; plaintext is not), or
# that the CronJob's schedule fires.

      Every OIDC client's secret is declared once, resolvable, ordered behind a real Flux
      dependency, and continuously reconciled — so an unresolved import placeholder can
      neither be merged nor silently persist in the realm.

        Assert the realm import, the SOPS Secret and the reconciler agree; that the Flux
        ordering is a real dependsOn edge; and run the reconciler's own selftest.
