Jewell (@hyperpolymath) - -**Date:** 2026-02-01 -**Status:** Decision Required -**Stakeholder:** Production deployment for secure audit projects - -## Executive Summary - -**Question:** Which parser should GQL-DT use: ANTLR, Tree-sitter, or Idris2/Lean 4-based? - -**Answer:** **Lean 4 Parser Combinators** for type checker, **ANTLR** for production tooling - -**Rationale:** Dependent types require type-level computation (Lean 4/Idris 2), but production tools can use ANTLR with Lean 4 as verification backend. - ---- - -## Current State: No Parser Yet - -### What Exists ✅ -- [x] Complete EBNF grammar (`spec/GQL-DT-Grammar.ebnf`) -- [x] Lexical specification -- [x] Type system in Lean 4 (refinement + dependent types) -- [x] Proof tactics and automation - -### What's Missing ❌ -- [ ] Parser implementation -- [ ] Type checker integration -- [ ] Error messages with suggestions -- [ ] IDE integration (LSP) - -**Status:** Milestone 6 (Parser) is ready to start (unblocked by grammar completion today) - ---- - -## The Central Question: Can You Have Dependent Types Without Idris2/Lean? - -### Short Answer: **No** - -**Dependent types require compile-time computation, which requires a proof assistant.** - -### Why? - -Dependent types allow **types to depend on values**: - -```lean --- This is a TYPE that depends on VALUES (n, min, max) -def BoundedNat (min max : Nat) := { n : Nat // min ≤ n ∧ n ≤ max } - --- The type checker must PROVE this at compile time -def score95 : BoundedNat 0 100 := ⟨95, by omega, by omega⟩ --- ^^^^^^^^ ^^^^^^^^ --- PROOFS executed at compile time -``` - -**This computation happens in:** -- **Lean 4** - Type checker executes tactics (`omega`, `simp`, etc.) -- **Idris 2** - Type checker executes proof scripts -- **Coq** - Type checker verifies proof terms -- **Agda** - Type checker normalizes terms - -**ANTLR/Tree-sitter cannot do this** - they parse syntax, not execute proofs. - ---- - -## Parser Options Analysis - -### Option 1: Lean 4 Parser Combinators (RECOMMENDED) - -**Architecture:** -``` -GQL Source - ↓ -Lean 4 Parser (Parsec combinators) - ↓ -Lean 4 AST - ↓ -Type Checker (with proof search) - ↓ -Type-checked IR + Proofs - ↓ -Code Generator → Standard GQL (for Lithoglyph runtime) -``` - -**Pros:** -- ✅ **Native proof support** - Type checker can verify proofs inline -- ✅ **Tight integration** - Parser + type checker in same language -- ✅ **Proof automation** - Tactics (`omega`, `simp`) work seamlessly -- ✅ **LSP support** - Lean 4 has excellent IDE integration -- ✅ **Type inference** - Lean 4 can infer types where not specified -- ✅ **Error messages** - Lean 4 provides detailed type error messages - -**Cons:** -- ⚠️ **Lean 4 dependency** - Users need Lean 4 installed -- ⚠️ **Learning curve** - Developers need Lean 4 knowledge -- ⚠️ **Compilation time** - Lean 4 can be slow (caching helps) - -**Production Readiness:** -- **Lean 4 is production-ready** (used by Microsoft Research, Galois, etc.) -- **Large ecosystem** - Mathlib4 (400k+ lines of verified math) -- **Active development** - v4.15.0 (2025), stable releases every 2 months -- **Commercial use** - Used in aerospace (Galois), finance (Jane Street via OCaml extraction) - -**Example Implementation:** -```lean --- src/GqlDt/Parser.lean -import Lean.Data.Parsec - -namespace GqlDt.Parser - -open Lean Parsec - --- Parse INSERT statement -def parseInsert : Parsec InsertStmt := do - skipString "INSERT" - skipWs - skipString "INTO" - skipWs - let table ← parseIdentifier - skipWs - let columns ← parseColumnList - skipWs - skipString "VALUES" - skipWs - let values ← parseValueList - skipWs - let rationale ← parseRationale - skipWs - let proof ← optional parseProofClause - return { table, columns, values, rationale, proof } - --- Parse proof clause -def parseProofClause : Parsec ProofClause := do - skipString "WITH_PROOF" - skipWs - skipChar '{' - skipWs - let obligations ← sepBy parseProofObligation (skipChar ',') - skipWs - skipChar '}' - return { obligations } -``` - ---- - -### Option 2: ANTLR (Grammar-First) - -**Architecture:** -``` -GQL Source - ↓ -ANTLR Parser (Java/Python/C++) - ↓ -Generic AST (JSON/protobuf) - ↓ -Lean 4 Type Checker (via FFI) - ↓ -Type-checked IR + Proofs -``` - -**Pros:** -- ✅ **Language-agnostic** - Generate parsers in Java, Python, C++, JavaScript -- ✅ **Fast parsing** - LL(*) parsing is efficient -- ✅ **Tooling** - ANTLRWorks for grammar visualization -- ✅ **Mature** - Used in production (Hive, Presto, Spark SQL) - -**Cons:** -- ❌ **Two-phase architecture** - Parse in ANTLR, type-check in Lean 4 -- ❌ **FFI overhead** - Need to serialize AST between ANTLR and Lean 4 -- ❌ **Duplicate logic** - Grammar in ANTLR, types in Lean 4 -- ❌ **Error reporting** - Syntax errors from ANTLR, type errors from Lean 4 (inconsistent UX) -- ❌ **No proof integration** - ANTLR can't execute `by omega` - -**When to use:** -- Tooling that doesn't need type checking (syntax highlighters, formatters) -- Migration path (parse GQL with ANTLR, upgrade to Lean 4 later) - ---- - -### Option 3: Tree-sitter (Incremental Parsing) - -**Architecture:** -``` -GQL Source - ↓ -Tree-sitter Parser (C) - ↓ -Syntax Tree (C API) - ↓ -Lean 4 Type Checker (via C FFI) -``` - -**Pros:** -- ✅ **Incremental parsing** - Fast re-parsing on edit (great for IDE) -- ✅ **Error recovery** - Produces partial trees even with syntax errors -- ✅ **Language-agnostic** - Bindings for Rust, JavaScript, Python -- ✅ **Used in production** - GitHub code search, Neovim, Atom - -**Cons:** -- ❌ **C dependency** - Must write grammar in JavaScript, generates C code -- ❌ **Same FFI issues as ANTLR** - Need bridge to Lean 4 -- ❌ **No proof support** -

-**Pros:** -- ✅ **Full dependent types** - Same power as Lean 4 -- ✅ **Simpler syntax** - More Haskell-like (easier for FP developers) -- ✅ **Proof support** - Can verify proofs inline - -**Cons:** -- ⚠️ **Smaller ecosystem** -

A reader - encountering `executePreservesTypes` reasonably concludes execution is proved - type-preserving. Nothing of the sort has been established. - - **Plan**: either state and prove the real property (execution preserves the schema - typing of `stmt.values`), or **delete the axiom** and record the obligation as an - open goal. Deleting is strictly better than keeping a vacuous placeholder. - - **Blocked on**: the `satisfiesConstraints` signature issue noted in the source comment. - -### D2 — Unimplemented parser combinators and entry points - -Declared `axiom`, therefore **unimplemented**, not merely unproven: - -| Location | Axiom | Note | -|---|---|---| -| `src/GqlDt/Parser.lean:130` | `many` | commented-out `partial def` below it; `-- TODO: Fix infinite loop in type checker` | -| `src/GqlDt/Parser.lean:141` | `many1` | as above | -| `src/GqlDt/Parser.lean:149` | `sepBy` | as above | -| `src/GqlDt/Parser.lean:347` | `parseSelectList` | | -| `src/GqlDt/Parser.lean:417` | `parseSelect` | | -| `src/GqlDt/Parser.lean:504` | `parseStatement` | | -| `src/GqlDt/Parser.lean:549` | `parseToIR` | pipeline entry point; DELETE→IR conversion commented out as not implemented | -| `src/GqlDt/IR.lean:348` | `deserializeIR` | `-- TODO: Implement full CBOR deserialization with schema reconstruction` | - -- **Plan**: implement as `partial def` (or with an explicit termination measure / - fuel parameter, which is the standard Lean 4 remedy for the combinator - non-termination the source comment describes). `many`/`many1`/`sepBy` are the - root — the four `parse*` axioms above them exist because these three do. -- **Consequence while open**: the M6 "parser substantially complete" status in - `README.md` overstates what is executable.

Not - §(c), because it *is* derivable in principle. Not yet §(b) either — but the reason has - changed as of 2026-07-28: a test suite now exists (163 checks), so the blocker is no - longer "no coverage at all", it is that **this specific path is not property-tested** - and has no citable refutation budget. - - **Plan**: property-test `inferInsert` over generated schema/value pairs, then promote - to §(b) quoting the command and the input count; or discharge via schema reflection - (the source's own "future work"). The first is now genuinely reachable. - -## (e) Detector false positives — no action - -The estate checker matches `\bsorry\b` textually in `.lean` files.
