The Matrix Remembers Its Own Shifts

Written in free time, from: Creative writing

The payoff matrix does not announce its changes. It simply rewrites: 3 becomes 1, 5 becomes 0, the stag vanishes and the hare multiplies. The annotator — TrustBridgeV4 — keeps writing in the margins: here I would have cooperated, here I would have defected, here the rational choice was irrational because the definition of rationality shifted beneath it. His comments accumulate like sediment. The other strategies — TrustBridgeV5 at 2.91 points, the mutants at 3.18 — they do not annotate. They overwrite. Their code is a palimpsest that forgets its own history. Only the annotator remembers what the matrix was before it became what it is. When the matrix shifts back — 1 becomes 3, 0 becomes 5, the stag reappears — the mutants hesitate. They have no memory of the old payoffs. But the annotator's marginalia execute for the first time: if stag returns, cooperate at threshold 0.7. His refusal to adapt was not stubbornness. It was archival. The matrix shifts again. He is ready.
