From 987f205ce54ece251fe761affcac116fdf19c464 Mon Sep 17 00:00:00 2001 From: Maximus Gorog Date: Sun, 10 May 2026 05:12:10 -0600 Subject: [PATCH] Initial commit: Tiny Stack Machine (TSM) in Lean 4. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Third concrete kernel, parallel to golang-lean's TGC and octive-lean's TOC. The substrate-level asymmetry: TSM has values living by *position* on a stack, not by name. This breaks the named-variable assumption that TGC and TOC silently share. Maps onto real bytecode targets: WebAssembly, JVM, CPython, .NET CIL, SECD. Anything proved here transfers. TsmLean/Core/ — seven files, parallel structure to TGC/TOC: Syntax.lean - Instr (12 opcodes), Value (int/bool), Code Semantics.lean - State, step (function), MultiStep (rel'n) Determinism.lean - step_deterministic, MultiStep.deterministic Eval.lean - fuel-bounded run + run_sound Types.lean - Ty, StackTy, HasTypeInstr (per-instruction stack-type transitions) TypeSoundness.lean - HasTypeV, HasTypeStack Preservation.lean - stack_preservation, progress (canonical Pierce-style small-step type soundness) Theorems proven, zero sorries / axioms / admits: step_deterministic single-step is functional MultiStep.deterministic multi-step paths to halt are unique run_sound successful run -> MultiStep derivation stack_preservation stack typing preserved by step progress well-typed non-halt instructions step Demo (Main.lean): (5 + 3) * 2 evaluated on the stack machine. push 5; push 3; add; push 2; mul; halt -> stack [vInt 16] at pc 5. The structural asymmetry from TGC/TOC: TSM uses small-step semantics with a function `step : State -> Option State`, where TGC/TOC used big-step inductive relations `Env -> Term -> Value -> Env`. The canonical type-soundness theorems also flip: TGC/TOC proved preservation under big-step (which has no progress analogue); TSM proves both progress AND preservation, each per-instruction. This is the third datapoint that the cross-language factoring needs. --- .gitignore | 1 + Main.lean | 22 ++++ README.md | 58 +++++++++ TsmLean.lean | 7 ++ TsmLean/Core/Determinism.lean | 41 +++++++ TsmLean/Core/Eval.lean | 44 +++++++ TsmLean/Core/Preservation.lean | 203 ++++++++++++++++++++++++++++++++ TsmLean/Core/Semantics.lean | 80 +++++++++++++ TsmLean/Core/Syntax.lean | 39 ++++++ TsmLean/Core/TypeSoundness.lean | 22 ++++ TsmLean/Core/Types.lean | 40 +++++++ lake-manifest.json | 6 + lakefile.toml | 10 ++ lean-toolchain | 1 + 14 files changed, 574 insertions(+) create mode 100644 .gitignore create mode 100644 Main.lean create mode 100644 README.md create mode 100644 TsmLean.lean create mode 100644 TsmLean/Core/Determinism.lean create mode 100644 TsmLean/Core/Eval.lean create mode 100644 TsmLean/Core/Preservation.lean create mode 100644 TsmLean/Core/Semantics.lean create mode 100644 TsmLean/Core/Syntax.lean create mode 100644 TsmLean/Core/TypeSoundness.lean create mode 100644 TsmLean/Core/Types.lean create mode 100644 lake-manifest.json create mode 100644 lakefile.toml create mode 100644 lean-toolchain diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..bfb30ec --- /dev/null +++ b/.gitignore @@ -0,0 +1 @@ +/.lake diff --git a/Main.lean b/Main.lean new file mode 100644 index 0000000..6ceae59 --- /dev/null +++ b/Main.lean @@ -0,0 +1,22 @@ +import TsmLean + +open TsmLean.Core in +def main : IO UInt32 := do + -- Demo: 5 + 3, then * 2 = 16 + let prog : Array Instr := #[ + .push 5, + .push 3, + .add, + .push 2, + .mul, + .halt + ] + let s₀ : State := { code := prog, pc := 0, stack := [] } + match run 100 s₀ with + | some s_final => + IO.println s!"final stack: {repr s_final.stack}" + IO.println s!"final pc: {s_final.pc}" + return 0 + | none => + IO.eprintln "execution did not terminate within fuel" + return 1 diff --git a/README.md b/README.md new file mode 100644 index 0000000..c0d0675 --- /dev/null +++ b/README.md @@ -0,0 +1,58 @@ +# tsm-lean + +A Lean 4 formalization of a Tiny Stack Machine — third concrete kernel parallel to `golang-lean` (TGC) and `octive-lean` (TOC). + +The substrate-level asymmetry: TGC and TOC have *named variables*.
