# Langfuse (LLM observability / eval viewer) — reads OTel-style traces and
# Ragas eval scores, not part of the RAG chat path itself.
#
# Multi-source Application: source[0] is the upstream `langfuse/langfuse-k8s`
# chart (not vendored into this repo); source[1] is this repo, providing only
# the override values file via the `$values` ref. Same disaster-recovery
# property as the other two Applications here: applying this file recreates
# the Application's structure, no follow-up step needed since this release
# carries no inline secrets (see infra/helm/langfuse/values-production.yaml
# for why: the app's own SALT/ENCRYPTION_KEY/NEXTAUTH_SECRET are chart-
# auto-generated on first install, and the Postgres password is read from
# the medical-chatbot-data release's existing Secret by name, never
# duplicated here).
#
# Deliberately targets the `medical-chatbot-data` namespace, not its own —
# see the values file's header comment for why (Secrets don't cross
# namespaces, and this needs the Postgres one that already lives there).
# This Application does NOT own the PersistentVolumeClaims that release
# depends on (postgres/qdrant) — it only adds new resources (its own
# ClickHouse/Redis/web/worker) into the same namespace. `prune: true` below
# only prunes resources Langfuse's own chart previously created, standard
# ArgoCD behavior scoped to this Application's own tracked resources.
