waitForServer() polled /api/monitoring/health but fell back to declaring the server ready once the port had merely accepted TCP connections for >= 3s, even if no HTTP response was ever received. On CPU-bound warmup (e.g. small VPS running Next.js standalone), the OS-level listener accepts TCP almost immediately while the request pipeline is still compiling, so the fallback fired within ~3-7s and the CLI printed 'OmniRoute is running!' 30-60s before any route actually answered. Classify each health poll into ready / fast-reject / hanging / not-listening: only a fast HTTP rejection (fetch error that is not a timeout, e.g. ECONNRESET before the route mounts) grants the original #2460 Windows-cold-start grace window. A request that times out with zero response (the reported #6800 symptom) resets the grace window instead of accumulating toward it. Regression tests: tests/unit/waitForServer-tcp-fallback-6800.test.mjs (new RED-then-GREEN probe from the bug analysis) and tests/unit/cli-waitForServer.test.mjs (existing suite realigned to the corrected contract, plus a new case for the hanging-socket scenario).
