Danila Fedorin	93f913a699	Clean up namespaces in the analysis framework ... - Wrap the forward-analysis framework in a Spa.Forward namespace so its generic names (analyze, result, joinAll, variablesAt, ...) no longer sit flat in Spa, matching the ConstAnalysis/SignAnalysis convention. - Merge the split Graph namespace in Graphs.lean by relocating buildCfg. - Use nested namespace Spa / Fixedpoint instead of Spa.Fixedpoint.

Danila Fedorin	2cfd0a2fb7	Lean migration: Phase 5 (language, CFGs, traces, Program) ... - Spa.Language.Base: Expr/BasicStmt/Stmt + HasVar relations; StringSet lifts to Finset String - Spa.Language.Semantics: Value/Env/Env.Mem, big-step relations, LatticeInterpretation (respects-≈ field drops out with =) - Spa.Language.Graphs: Graph with nodes : Fin size → List BasicStmt (Vec lookup lemmas lift to Fin.append_left/right), comp/link/loop/ skipto/singleton/wrap/buildCfg, predecessors via List.finRange - Spa.Language.Traces: Trace + EndToEndTrace (Prop-valued) - Spa.Language.Properties: trace embeddings, loop lemmas, buildCfg_sufficient; the 80-line Fin-disjointness block reduces to castAdd_ne_natAdd + mathlib list lemmas - Spa.Language: Program (vars via Finset.sort — toList is noncomputable) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-09 19:30:42 -07:00
