  "summary": "Static review of virtual-thread adoption correctness at scale: pooling/capping anti-patterns, a VT migration that strips a downstream resource bound without re-imposing a Semaphore, JDK-version-gated carrier pinning (JEP 444 vs JEP 491), ThreadLocal cost at scale, StructuredTaskScope preview status, and classic executor/visibility hygiene. Reads source and sanitized configuration only.",

  "security_notes": "Static review only — reads Java source (Thread.ofVirtual/newVirtualThreadPerTaskExecutor call sites, ExecutorService construction, synchronized blocks, ThreadLocal usage) and sanitized configuration (pool-size properties, rate-limiter config, any JFR/trace text the user pastes as plain text); never runs a build, invokes a JDK, attaches a profiler or JFR recorder, or opens a live thread dump/DB/broker connection. Never requests connection strings, credentials, tenant identifiers, or customer data.",
