Changelog

All notable changes to cargoxx will be documented in this file.

[Unreleased]

M0 repo skeleton: hand-written CMakeLists.txt, bootstrap flake.nix, empty C++23 module units for every component listed in TECH_SPEC.md §1 (util, exec, manifest, lockfile, layout, linkdb, resolver, codegen, cli), root module cargoxx, and a stub main.cpp that builds an empty cargoxx binary.
.clang-format (LLVM, 100-column) and .gitignore.
SPEC.md, TECH_SPEC.md.
M1 foundation in cargoxx.util: ErrorCode (numbers per TECH_SPEC.md §4), Error, Result<T> = std::expected<T, Error>, and format(Error) rendering error[Ennnn]: ... with optional --> path:line:col and hint: lines. format lives in src/util/error.cpp as a module implementation unit.
Catch2 v3 wired through flake.nix (libc++-built override) and registered in CMake; tests/util_error.cpp covers six format cases via catch_discover_tests.
cargoxx.manifest public types (Package, Dependency, BuildSettings, Edition, Manifest) and parse(path) returning Result<Manifest>, backed by toml++ vendored as third_party/toml.hpp. Unknown keys in [package] / [build] and unknown top-level keys are rejected; reserved fields (description, repository, [dev-dependencies], [features], [workspace]) are accepted. tests/manifest_parse.cpp covers 17 cases.
