# logarchiver — replaces the vector-archiver leg. Independent JetStream durable
# consumer (archiver) that seals raw logs to S3 as zstd + OpenPGP objects and
# indexes each object in ClickHouse (logs.archive_index). Acks only after the
# object is in S3 AND indexed. Reuses the same NATS/S3/CA wiring the Vector
# archiver used; the OpenPGP public key is delivered as a mounted file.
