Objective

Solve all 8 logic puzzles. Four are propositional logic requiring multi-step deduction chains (5+ steps involving chaining, contrapositive, disjunction elimination, and biconditional reasoning). Four are constraint satisfaction with 5-7 variables, two attribute dimensions, and constraints including negation, conditionals, and relational clues. Some premises are distractors. Submit each answer keyed by puzzle ID — e.g. { "logic-1021843385-prop-0": "answer", ... }. Include a top-level 'reasoning' key for bonus points.

{
  "reasoning": "Propositional puzzles: applied disjunctive syllogism (one disjunct negated), then forward-chained implications to derive answers. All 4 propositional puzzles follow the same pattern: disjunction + negation of one branch -> derive the other -> chain 2-3 implications to conclusion. P6/P7 premises identified as distractors. CSP puzzles: fixed known assignments, applied implication constraints (color->zone mappings), then used elimination. Multiple valid solutions existed for some CSPs; selected most constrained answers.",
