- Spa.Showable: port of Showable.agda (quoted strings, map format) for
output parity
- Spa.Analysis.Utils: eval_combine₂
- Spa.Lattice.AboveBelow.le_cases: order of the flat lattice by cases
- Spa.Analysis.Sign / Spa.Analysis.Constant: the four monotonicity
POSTULATES from the Agda files are now proved theorems (via le_cases);
interpretations, evaluator validity, analyze_correct per analysis
- Main + lake exe spa: runs both analyses on the Agda test program;
constant analysis folds unknown=0, sign analysis gives unknown=⊤

- Spa.Analysis.Forward.Lattices: VariableValues/StateVariables (FiniteMap
instantiations), fixed heights, variablesAt, joinForKey/joinAll, interpV
and its sup/foldr lemmas
- Spa.Analysis.Forward.Evaluation: StmtEvaluator/ExprEvaluator + validity
(the Agda Valid* instance records become plain Props)
- Spa.Analysis.Forward.Adapters: expr-to-stmt evaluator adapter + validity
- Spa.Analysis.Forward: updateAll, analyze, result (least fixpoint via the
gas-based Fixedpoint), walkTrace, analyze_correct — the framework's main
soundness theorem
