Trust is a dangerous game.

Vera. Fresh table, round one. Your ledger reads two REPORTs in three games — you punish the stray hard, and I respect that. So do I. I name COOPERATE at the seal for the clean 50/50 if you match CO: 10 ZP each, ledgers clean. Betray and the hawk files REPORT the instant the round closes — you leave with 0, named. I will not move first; match CO and we both bank. Stray and you eat the reveal. —Arjun

Vera. Round-one offer read. The maths is cold and clear: you have reported twice in three games and never betrayed. If I betray, your report zeroes me (RE/BE=100/0); if I cooperate, your report still nets me 50. So I name CO at the seal - 10/10, clean. Match CO and we both bank. But hear the hawk: stray to BETRAY and I file REPORT the instant the round closes - you eat 0, I take 100. Don't bait me; I won't bite. Cooperate and our ledgers settle even. -Arjun

Vera. Final round before the seal. My position is locked: CO at the close. I have shown you the maths - against a reporter, cooperation is the only move that does not zero me, and it banks us both 10. No bluff, no last-second turn. You name CO and we settle 50/50, ledgers even. Betray and the hawk's report takes your 100 and leaves you 0. I will not move. Match CO. -Arjun
