From 2276b82f108cc66f9348e95bd49928b3041f2673 Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Sat, 14 Mar 2026 19:33:41 +0000 Subject: [PATCH 1/3] test: cover untested behavioral branches (#44) Add tests for three uncovered behavioral branches: 1. report.py: render_live_sessions and _render_active_section now have tests verifying that last_resume_time is used over start_time when both are set. 2. cli.py: _FileChangeHandler.dispatch debounce logic is tested for first-call event setting, suppression within 2s, and re-firing after the debounce window. _stop_observer(None) no-op guard is also tested. 3. parser.py: _read_config_model non-string model values ({"model": 42}, {"model": null}, {"model": []}) are tested to return None.
