# ── Clustered secret replication: the pull-only gRPC hub (scadaproj#3) ─────────
#
# Central hosts the hub on its EXISTING h2c control-plane listener (CentralGrpcPort
# 8083, alongside CentralControlService); each site node sweeps it on an interval and
# writes what it pulls into its OWN local SQLite store. Nothing but ciphertext crosses
# the wire, so every participating node must resolve the SAME KEK.
#
# ENABLED ON FOUR NODES ONLY: the central pair (hub) and the site-a pair (followers).
# site-b and site-c are deliberately left without it, so the default-OFF posture is
# proven side by side on one rig — exactly as site-a is the rig's only LocalDb-replicated
# pair. A node with no Secrets__* override keeps the shipped appsettings default
# (Replication:Enabled=false, Mode=SqlServer) and composes a plain local store.
#
# ALL VALUES HERE ARE DEV-ONLY and committed under the same exception as the mesh PSKs
# and the ApiKeyPepper above: a local docker rig needs a working credential in source
# control to boot. Production supplies the KEK out of band (ZB_SECRETS_MASTER_KEY, never
# committed) and the hub token from appsettings/env — NEVER as a ${secret:} reference,
# since resolving one is what the hub exists to make possible.
x-secrets-hub-env: &secrets-hub-env
  # DEV-ONLY KEK — NOT a real key. Identical on all four participating nodes: only
  # ciphertext replicates, so a node with a different KEK fails closed on resolve with a
  # kek_id mismatch that reads like corruption but is a deployment error.
  ZB_SECRETS_MASTER_KEY: "zZiBWuoaVMbJmGXToLk9Lakw0iJozXoL/7Gxac3GwJ4="
  # The appsettings default is the relative "scadabridge-secrets.db", which resolves to
  # /app — inside the image's writable layer, so it is destroyed by any container
  # recreate and unreachable from the host. /app/data is the node's own mounted volume
  # (the one LocalDb already uses on sites; added to the central pair for this).

  # DEV-ONLY shared bearer token — NOT a real secret. Presented by every follower and
  # verified by the hub's fail-closed SecretsHubAuthInterceptor. Must be IDENTICAL on the
  # hub and every follower; an unset token is a startup failure on both halves.
  Secrets__GrpcHub__BearerToken: "secrets-hub-docker-dev-token"

# Site half of the same section. NOTE the asymmetry with
# ScadaBridge:Communication:CentralGrpcEndpoints, which is a LIST that fails over across
# the central pair: the hub client dials a SINGLE endpoint, so a sweep against a stopped
# central-a stalls rather than failing over to central-b. That is survivable — the sweep
# is best-effort and the node keeps serving its full local last-known-good store — but
# secrets stop converging until central-a returns.
