Part 3's .rep previously declared only slots. Broaden it to cover the whole
Qt Remote Objects contract a universal UI backend can author, so the tutorial
teaches the breadth of .rep, not just call-and-return:
- SLOT(void announceVersion()) — a void / fire-and-forget slot
- PROP(QString versionEvent READONLY) — fed by a typed calc_module event
subscription armed in onContextReady()
- PROP(int computeCount READONLY) — a slot-driven counter (int PROP)
- PROP(int memory READWRITE) — a register the QML view writes back
- SIGNAL(computed(QString op, int result)) — a backend -> view push
The backend gains onContextReady() (event subscription) and a record() helper
(bumps computeCount, emits computed); the QML view gains a Connections block,
Computations / Last-op labels, and a Memory register with Store/Clear buttons
that assign backend.memory. Step 9's UI test drives each surface — the slot
return value, the int PROP (Computations: 1), the signal payload (add = 8),
and the READWRITE round-trip (Memory: 0 -> 8) — and the closing .rep pattern
table now marks every row exercised except Model.
Regenerated outputs/ (md + calc_ui_cpp sources + screenshots). Verified end to
end via the doctest chain (Part 1->2->3): 69/69 steps, UI test 14/14.
