# W7 — established selective app-transport loss
Before [701e13c](https://git.cafe/pingdotgg/t3code/commit/701e13cebb040d8433cd9aefb803ddd0d58c41d6); after [37441e9](https://git.cafe/pingdotgg/t3code/commit/37441e905194b062345c76d81caacd00d77ef5e5).
Environment: Linux x86_64 fs-33; Chromium148.0.7778.96 / Playwright headless shell1223; no device emulation; DPR1; zoom/font scale100%; dark; reduced motion reduce; full1440×900. Date constructor frozen2026-11-03 00:00 UTC; native Date.now/timers; same synthetic stopped history, server-generated message minute00:44 UTC, top scroll.
Load cached stopped thread while reachable and wait for live; cut ONLY established app /ws with close4001 and reject subsequent /ws attempts, emit offline; hold8 real seconds; restore app transport and emit online; await connected stopped history. Auth, descriptor, HTTP/static and Vite remain reachable. This does not claim device-wide OS offline.

Every selected still awaited fonts/network idle, reduced motion, then two pixel-identical frames500ms apart. Every selected still/diff and decoded recording frames were opened and reviewed. Diff0 amplifies every nonzero RGB delta in magenta over20%-brightness after; DiffT16 uses max RGB delta>16/255. No stale overlay, ghosting, loading still, mismatched viewport or unrelated highlighted region in selected proof.
