Played the demo through to the REJECTED ending on desktop. Your three questions in order.
1. Nowhere across the three rounds — the loop carries a minute easily. The budget footnote ("$8,000 is the combined monthly salary budget for all three employees") is the best beat in it.
2. "Read his paperwork first", all three times; the two dialogue replies read as flavour beside it. Inspecting was clear, and the reason is mechanical: the primary button sits disabled reading "Mark the contradiction first", then relabels to "Put the evidence in front of him" once a clause is marked. That taught the interaction without a tutorial line.
3. I couldn't see the replay button when the verdict landed. With the browser content area 648px tall (an ordinary 1366x768 laptop), the ending panel is 482px holding 690px of content: "Get the Full Edition — $4.99" ends at 596px and is visible, but "Save your decision" starts 98px below the panel's bottom edge and "Try a different approach" 142px below. A 10px scrollbar is there, so it's reachable rather than lost — but the replay prompt is off-screen at the exact moment you're asking about.
