## Title

    Proposed fix: [Microsoft JDBC Driver for SQL Server >= 10.2] '"encrypt" property is set to "true" and "trustServerCertificate" property is set to "false" but the driver could not establish a secure co

## Body

    Recommended action: Import the server's CA into the JVM truststore (or use trustStore connection properties) and connect by a DNS name in the cert; for local development only add encrypt=true;trustServerCertificate=true (or encrypt=false if the server doesn't force TLS).
    
    Option: Trust the CA (prod) or opt out (dev) [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. Prod: keytool -importcert the CA into a truststore; set trustStore/trustStorePassword connection props
    2. Dev: jdbc:sqlserver://localhost:1433;encrypt=true;trustServerCertificate=true
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
