Front Office · Trade builder preview

Recorded data (Wk 7, 2026-10-20), nothing live is sent. Every write request is blocked and the Send step is disabled. The trade checks are canned examples of the server's answer.

1. Open Front Office → Trades (opens on the Trade builder; Trade finder is the second choice).
2. Choose a team, tap Add on players and picks (add a third team for a three-team trade). Watch Trade impact (cap, lineup, validation) update, then add a note and tap Send offer → Yes, send to see the confirmation and the “disabled in preview” message.
3. Try the extension: with Marvin Harrison Jr. added, pick a 1- or 2-year extension in his row (a scenario only; nothing is saved). Click a player's name to open the same player panel as the rest of Front Office; closing it returns you to the trade as you left it.
4. Validation states to try: nothing selected (No trade proposed), one side only (Incomplete trade), both sides (Looks fine so far), three players from one side (Needs an acknowledgment), four (Not allowed).
5. Labels: Recorded data = the 2026-10-20 rosters and scores; Calculated = cap and lineup math run live in the page by the Front Office's own engines; SIMULATED server check = canned examples of the server's answer.
6. Try: calendar closed · calendar unreadable · server unreachable.
