Line 287 uses
Duration.ofSeconds(5).toMillis()withTimeUnit.MILLISECONDS, which is correct but verbose. Consider usingexecutor.awaitTermination(5, TimeUnit.SECONDS)directly for better readability.The same pattern appears at line 435.

In @.docs/TEST_RESULTS.md:
- Line 19: Update the TEST_RESULTS.md to clarify mismatched dates: identify the
"common environment" date entry and the "k6" and "observability" sections and
either align the common environment date to 2026-05-18 or add a short note
explaining that the common environment entry reflects a different run
(2026-05-16) while the k6 and observability sections reflect the later
comprehensive run (2026-05-18); make the change around the table header labeled
"Date" and the k6/observability section headings so readers understand which
date applies to which test results.
In `@docker-compose.yml`:
- Around line 54-55: Remove the insecure fallback defaults for Grafana admin
credentials by eliminating the ":-admin" defaults for GF_SECURITY_ADMIN_USER and
GF_SECURITY_ADMIN_PASSWORD in the docker-compose environment block (the two
environment keys GF_SECURITY_ADMIN_USER and GF_SECURITY_ADMIN_PASSWORD). Change
them to require explicit environment values (e.g. use ${GRAFANA_ADMIN_USER} and
${GRAFANA_ADMIN_PASSWORD} with no defaults), and update any deployment docs or
.env.example to show secure values so the variables are always set explicitly.
Ensure no other code relies on the old defaults before removing them.
In `@src/main/java/com/coinflow/config/SecurityConfig.java`:
- Line 50: The current SecurityConfig exposes /actuator/prometheus publicly;
update the HttpSecurity configuration (in SecurityConfig, e.g., the method that
builds the SecurityFilterChain or configure(HttpSecurity http)) so that
"/actuator/health" and "/actuator/info" remain permitAll() but
"/actuator/prometheus" is not permitAll — instead require authenticated() (or
add a JWT authentication requirement) or apply an IP/network restriction via
hasIpAddress(...) or a custom request matcher; adjust the requestMatchers call
accordingly and ensure any authentication entry point or JWT filter used by the
application (the same one wired by SecurityConfig) will protect the prometheus
endpoint.

Consider clarifying the relationship between test run dates.
The common environment date (2026-05-16) differs from the k6 and observability test dates (2026-05-18). If these are separate runs, consider adding a note explaining which sections use which environment, or updating the common environment date to match the latest comprehensive run.

docker-compose environment variable expansion syntax ${VAR?message} support
💡 Result:
Docker Compose supports the ${VAR?message} syntax for environment variable interpolation [1][2]. This syntax is used to enforce that a required variable is set and non-empty; if the variable is unset or empty, Docker Compose will exit with an error message containing the specified message [1][3]. The following variations of this syntax are supported: - ${VAR:?message}: Exits with an error if VAR is unset or empty [1][2]. -

Remove insecure default Grafana admin credentials.
admin/admin fallback defaults are risky and frequently leaked into shared environments. Require explicit env vars instead of permissive defaults.

Restrict /actuator/prometheus access to authenticated users or internal networks.
Line 50 exposes detailed runtime and system metrics without authentication, including JVM statistics, request latencies, and application-specific metrics that can enable reconnaissance. Keep /actuator/health and /actuator/info public if needed for monitoring, but protect /actuator/prometheus via authentication (e.g., JWT token requirement) or restrict it to internal network access only.
