PR #34 added per-stage Auto timing logs (single-mode probing took..., hybrid candidate gathering..., hybrid probing took...) at logger.info level, but navi-offroute has no logging config, so Python's last-resort handler dropped everything below WARNING and the lines never reached stderr/journal. This one-line logging.basicConfig(level=logging.INFO) in app.py opens the gate so those lines surface in journald, letting us localize the 6-7s baseline Auto latency on in-town routes. No other changes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
