+Probed `muse`, `pip`, `opm` via CDP `Runtime.evaluate` in each netns:
+
+| Check | muse | pip | opm |
+|---|---|---|---|
+| `navigator.onLine` | true | true | true |
+| `[role="alert"]` with content | 0 | 0 | 0 |
+| Toasts | 0 | 0 | 0 |
+| `Allow … to share` in body text | no | no | no |
+| Offline/rate-limit markers | none | none | none |
+| Typing indicator | absent | absent | absent |
+| Composer present | yes | yes | yes |
+
+Additional observations:
+- **Title unread prefix:** pip's title was `(1) Chat — operator-pip` — the title
+  gains an `(N)` prefix when unreads exist. State detectors should use
+  `startsWith('Chat —')` on the *end* of the title or strip a leading
+  `\(\d+\)\s*` before comparing.
+- **Shared browsers:** another agent drove pip's browser mid-probe (URL changed
+  from `/thread/<uuid>` to `/` and back, panel toggled between probes).
+  Fleet browsers are a shared resource — re-probe immediately before acting,
+  and never treat a minutes-old snapshot as current state.
+- **Settled-state counts are ranges:** shimmer spans 1 (doc said 2),
+  `role="status"` 3–4 (doc said 4–7), buttons 46–57 on settled thread pages.
+  The cheat-sheet's `buttons > 30` threshold still holds; don't hard-code
+  exact counts.
