+### Process model

+Opteryx is an in-process engine, and this entry runs it the way it is deployed:
+as a long-lived service. `start` launches `server.py`, a standard-library HTTP
+wrapper that imports `opteryx` and waits; `query` posts each statement to it.
+This is the same shape as the pandas/polars entries.

+"""
+Long-lived Opteryx query server for the ClickBench entry.
+
+Standard library only — the venv holds opteryx-core and nothing else.
+
+Routes (127.0.0.1:8421):
+    GET  /health  -> 200, body = opteryx version. No query is run: ./check
+                     calls this before every cold try, and a query here would
+                     warm the engine ahead of the measurement.
+    POST /query   -> body = one SQL statement. Response body = the result as
+                     TSV (header + rows); header X-Elapsed = seconds spent
+                     draining execute_to_morsels.
+
+The clock covers exactly what the embedded entry's clock covered: draining
+`execute_to_morsels`. Session construction (warm: ~0.04ms) and TSV rendering
+are outside it.
+
+One session per request; the engine's footer and schema caches are process
+scoped, so tries 2..3 of a query see a warm process. There is no result cache.
+
+A query that raises is not caught: the handler dies, the connection closes with
+no response, `./query` exits non-zero and the driver records null. The traceback
+is in server.log.
