- Line 173: Remove the stray ok token before the CassandraConfig type
declaration so it reads as a valid type CassandraConfig struct declaration and
the package compiles.
In
`@src/control-plane-services/event-ledger/internal/db_client/cassandra/common.go`:
- Around line 525-527: Update the GetTLSConfigFromBase64 error branch to remove
the local p.logger.Warn call and return the error wrapped with the context
“create Cassandra TLS config” using %w.
- Around line 511-524: Update the Cassandra TLS setup around cluster.SslOpts to
handle CA-only configurations for both CACertPath and CACertB64, either enabling
TLS with the CA or rejecting the configuration during validation. Preserve
existing certificate/key handling, add regression coverage for both CA-only
input forms, and update the Cassandra connection diagram only if it documents
this flow.

TL;DR
Add configurable Cassandra CA certificates so Event Ledger can verify Cassandra server certificates instead of relying on
insecure-skip-verify.Additional Details
Event Ledger currently supports a client certificate and private key but cannot load a Cassandra-specific CA trust bundle.
This change:
database.cassandra.ca-cert-b64anddatabase.cassandra.ca-cert-pathtls.Config.RootCAsCaPathDeployment configuration changes are maintained separately and should be rolled out only after an Event Ledger image containing this change is available.

Validation completed:

Bazel validation was not run locally because Bazel is unavailable in the development environment; CI should run the added
