@@ -60,3 +60,37 @@ host and broker processes. The unit template has no `--pm`
 either. Decision 91's watched `--pm` restart (Mos's) hasn't happened.
 Until a PM runs, no S7 piece can be answered. Whether the PM picks up
 6b5b7aef when it launches, I haven't checked.

+## 2026-10-12T18:56Z PM running; both reachability checks answered (Mos sage-0096, sage-0097)
+
+Mos added a temporary drop-in,
+`~/.config/systemd/user/mosaic-bus@mosaic-stack.service.d/pm.conf`, that
+sets `bus start %i --pm`, and restarted the unit at 2026-10-12T18:53:34Z.
+The journal shows "launched pm: run r0566c6d9e459, claude-code
+claude-opus-5-5", and `scripts/mosaic launches list` shows the run,
+by jason. The bus now runs the checkout as of that restart. Row 85 (#1579)
+removes the drop-in when it lands.
+
+This corrects the last line of the 18:49Z entry. The PM's runner calls
+message.receive as it starts, and the broker returns every pm message not
+yet delivered (packages/harness/src/runner.mjs:314,
+packages/bus/src/broker.mjs:771-777). So a message queued before the
+launch is answered.
+
+Two reachability checks, neither a piece (Mos's view, and mine):
+- 6b5b7aef ("Can you hear me now?"), sent before the PM ran. It was
+  answered by c61d6328, RESULT re 6b5b7aef, from Jason's screenshot via Mos.
+  His `talk` had timed out by then, so he saw it in a second call.
+- a8df1e12, answered by 375bfb6a (same source).
+
+The run directory shows turn 1 at 18:53:35Z and turn 2 at 18:55:12Z,
+both with empty stderr, and runner.log has no failure line. I read only
+file names, sizes and the `runner:` lines, never turn content.
+
+Plain `mosaic` (the Q81 wrapper) still gets human-required (#225 c60).
+Until row 85 lands, Jason uses the full path,
+`/mnt/storage/src/mosaic-stack/scripts/mosaic talk pm "..."`, or the
+Console. Notifier off: notify.json sets binding null, so it was off
+before the restart too.
+
+S7 piece 1 is Jason's next real Mosaic Stack request.
