- run.sh: start/stop/restart/status/logs for the whole stack, JAVA_BIN override, pinned to /usr/lib/jvm/java-21-openjdk (Java 25 breaks logback ThrowableProxy inside fat jars and kills Tomcat threads) - -Xmx320m per service, health-gated startup, logs/ dir (gitignored) - README: requirements, run.sh workflow, full current feature list - verified: 25-round load test across all pages under JDK 21 — 0 failures
