Merge Risk: 🟡 Moderate · up to Standard TLS configuration may not accept the documented flag, and insecure deployments can fail because of a TLS directory that should be ignored. Resolve these CLI startup paths before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

name:"tls-server-certs-dir", preserving the flag name documented in its help
text and the existing TLS_SERVER_CERTS_DIR environment variable mapping.
- Line 61: Update StandardOptions so MTLSCertificates(c.TLSCertsDir) is applied
only when c.Insecure is false; ensure --insecure bypasses TLS certificate
loading and ignores invalid or missing TLS directories.

Use the documented TLS flag name.
TLSCertsDir has no name tag. Kong derives --tls-certs-dir, so the --tls-server-certs-dir flag named in the help text is rejected. Set name:"tls-server-certs-dir" to preserve the standard CLI contract. (github.com)
Proposed fix
- TLSCertsDir string `env:"TLS_SERVER_CERTS_DIR" help:"Directory containing server certs (tls.key, tls.crt) and the CA used to verify client certificates (ca.crt)."`
+ TLSCertsDir string `name:"tls-server-certs-dir" env:"TLS_SERVER_CERTS_DIR" help:"Directory containing server certs (tls.key, tls.crt) and the CA used to verify client certificates (ca.crt)."`📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Skip TLS certificate loading in insecure mode. StandardOptions applies MTLSCertificates(c.TLSCertsDir) before Insecure(c.Insecure). A non-empty invalid or missing TLS directory can therefore return an error before insecure credentials are applied. Could you skip MTLSCertificates when c.Insecure is true so --insecure ignores the TLS directory as documented?
