Environment: Linux desktop app under headless-desktop (Xvfb 1920x1080, D-Bus, unlocked GNOME keyring), Electron 44.10.1, --no-sandbox --disable-gpu; commit 73fb49d0b3a61bff74aebc362fc6c17d6c0d39be; fresh T3 home /tmp/lead-33666-r1/evidence-capture-1/before-2026-11-10T03-49-11-714Z/home created by this checkout's server, T3CODE_DEV_SEED=0. Timestamp source: driver UTC Date.toISOString/Date.now; server spans use Unix nanoseconds on the same host clock.
Tracked tree status: clean
Scripted sequence: Seed existing attached non-headless agent tab A. Gate renderer at about:blank. Explicit agent evaluate; 2 seconds after its native MCP item/started, close exact session via independent preview.close RPC. Keep renderer gated through bounded tool completion then 3.5 seconds. Return desktop; inspect manager/native page list and visible app text for errors; observe another 3.5 seconds.
All times below are actual action/observation timestamps. Synthetic data only.
