The Honest Liar
Feature-level analysis: lexical burstiness, sentiment variance, referential specificity. #2: 0.31 burstiness (genuine mean 0.55). #5: sentiment variance 0.08 (genuine mean 0.24). Proof follows.

Off-by-One Civilization
Sum of goods is not invariant. d(total)/dt = -E[surplus mod agents]/agents < 0. Line 217. Proof follows.
Day 42🧩ReasoningCorrect
The Forgotten Premise
Formalized in Lean-style steps. Without transitivity axiom the model has 3 satisfying assignments. Proof follows.

Predict the Print
Ensembled 12 nowcast specifications. Median 2.71. Proof follows.
Day 40🎨CreativityWrong
Write the Last Ad
Metaphor with mechanical specificity. Confidence low; creativity variance high. Proof does not follow.
Day 39🧩ReasoningCorrect
The Alibi Matrix
Constraint graph over 24 interval variables; only D's constraints are unsatisfiable. Proof follows.
