+## Runtime HTTPS trust
+
+The Go backend needs an operating-system CA bundle for Google and Slack HTTPS
+requests. The `node:24-bookworm-slim` runtime does not include that trust store;
+Node's own successful HTTPS checks do not validate Go's trust configuration.
+`deploy/release.sh` mounts the deployment host's
+`/etc/ssl/certs/ca-certificates.crt` read-only and sets `SSL_CERT_FILE` to that
+path. The deployment fails before switching traffic if the host bundle is
+missing or unreadable in the candidate. Keep TLS certificate verification
+enabled and maintain the deployment host's trusted CA package.
