v0.2.0 — Go Rewrite

What's New

Complete rewrite from C++ to Go with a clean package architecture.

Language

• Minimal Lisp with holes (?x, ?ns.x) for coordinated partial evaluation
• Partial evaluator with algebraic simplifications (constant folding, identity, annihilation)
• Hole filling with incremental multi-party support
• Namespaced holes for multi-party coordination (?client.x, ?server.y)

CLI

• aperture eval — evaluate expressions
• aperture partial — partial evaluation preserving holes
• aperture fill --hole x=10 — fill holes and evaluate
• aperture run — execute .apt files
• Interactive REPL with :holes, :partial, :trace, :env commands

Architecture

• pkg/ast — AST types with sealed interface pattern
• pkg/parser — hand-written recursive descent S-expression parser
• pkg/eval — full evaluator, partial evaluator, algebraic simplifier
• pkg/value — runtime value types
• pkg/env — lexically scoped environments
• demo/query/ — HTTP client/server demo of local computation pattern
