Add complete formal academic documentation covering: Proofs and Metatheory: - Type system soundness (progress/preservation theorems) - Quantitative type theory (linearity proofs, semiring laws) - Algebraic effects formal semantics (handlers, row polymorphism) - Ownership/borrowing verification (memory safety proofs) - Row polymorphism (unification, coherence) - Dependent types and refinement types (normalization, SMT) - Coherence and parametricity (free theorems) - Type inference algorithm specification Formal Verification: - Operational semantics (small-step, evaluation contexts) - Denotational semantics (domain theory, logical relations) - Axiomatic semantics (Hoare logic, separation logic) Mathematical Foundations: - Categorical semantics (LCCCs, graded comonads, Freyd categories) - Logic foundations (Curry-Howard, linear logic correspondence) - Complexity and decidability analysis White Papers: - Language design rationale and related work comparison Mechanized Proofs (stubs): - Coq formalization structure - Lean 4 formalization structure - Agda formalization structure All documents include: - Complete formal definitions and inference rules - Detailed proof sketches and theorem statements - Implementation dependencies marked with [IMPL-DEP] tags - References to academic literature - Connections to the existing codebase (lib/ast.ml, etc.)
This commit establishes the foundation for implementing AffineScript: Design Documents: - DECISIONS.md: Key design decisions for runtime, effects, WASM, SMT, etc. - ROADMAP.md: Phased implementation plan (9 phases, version milestones) Compiler Infrastructure (OCaml stubs): - lib/symbol.ml: Symbol table for name resolution - lib/resolve.ml: Name resolution pass - lib/types.ml: Internal type representation - lib/unify.ml: Type/row/effect unification - lib/typecheck.ml: Bidirectional type checker - lib/quantity.ml: QTT quantity checking - lib/borrow.ml: Borrow checker Runtime (Rust): - runtime/Cargo.toml: Crate configuration - runtime/src/lib.rs: Entry point - runtime/src/alloc.rs: Memory allocator - runtime/src/effects.rs: Effect handling (evidence-passing) - runtime/src/panic.rs: Panic handling - runtime/src/ffi.rs: Foreign function interface - runtime/src/gc.rs: Optional garbage collector Tooling (Rust): - tools/affinescript-lsp/: Language server protocol implementation - tools/affine-pkg/: Package manager (Cargo-inspired) - tools/affine-doc/: Documentation generator All stubs contain comprehensive TODOs for future implementation.
- Fix typecheck.ml: Rewrote to use correct AST constructors (ExprVar, ExprLit, ExprLambda, etc. instead of EVar, ELit, ELam) and correct field names (id.name/id.span instead of id.id_name/id.id_span) - Fix quantity.ml: Updated to match actual AST structure with proper expression constructors (ExprVar, ExprApp, ExprLet, etc.) and field names for quantitative type checking - Fix borrow.ml: Rewrote borrow checker to use correct AST expression and pattern constructors, fixing ownership verification - Fix resolve.ml: Already fixed in previous session, confirmed working with correct ident field access patterns - Fix parse_driver.ml: Added Fun.protect for resource-safe file handling, ensuring file handles are closed on exceptions - Fix error.ml: Added bounds checks (line > 0, max 0 col-1) to prevent invalid negative indices in error message formatting - Fix affinescript.opam: Removed duplicate dune constraint that caused opam parser warnings - Fix runtime/src/gc.rs: Added checked_add for allocation size to prevent integer overflow attacks on 32-bit systems These fixes address 8 critical issues that would prevent compilation and 2 security vulnerabilities (resource leak, integer overflow).
- Replace innerHTML with safe DOM APIs (createElement, textContent) - Add URL validation to prevent open redirect attacks - Add null checks for search index entries - Remove template literal HTML construction Fixes Semgrep finding: javascript.browser.security.insecure-document-method
