# Changelog

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

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.2.0] - 2026-04-07

### Added

- **Monolith artifact mode** (`mode: :monolith`): projects selected packages and
  their test-view closure into a single flat Mix project under
  `dist/monolith/<package>/` instead of `dist/hex/<package>/`. Merges `lib/`,
  `test/`, `priv/`, config, and migrations from all selected projects with
  automatic file-conflict resolution and deterministic migration re-stamping.
- `monolith_opts` artifact key: supports `shared_test_configs` (list of project
  ids whose `test.exs` are included in the monolith root config) and
  `extra_test_deps` (atoms referencing manifest-declared dependencies to force
  into test-only deps in the generated mix file).
- Weld.Config.Generator: generates a merged config tree for monolith artifacts,
  sanitizing workspace-app config calls from static copies while preserving full
  originals under `config/runtime_sources/` for bootstrap use.
- Weld.Projector.Monolith, Weld.Projector.Monolith.FilePlan,
  Weld.Projector.Monolith.Migrations, Weld.Projector.Monolith.MixFile,
  Weld.Projector.Monolith.TestHelper: internal modules implementing monolith
  projection, file merging, migration merging, mix file generation, and test
  helper synthesis.
- `Plan.projects_for_view/2` and `Plan.external_deps_for_view/2`: view-scoped
  project and dependency queries used by monolith projection.
- Git/GitHub-only manifest dependencies: `requirement` is now optional when
  `opts` include `:git` or `:github`, enabling manifest-declared git deps without
  a version constraint.
- Monolith verifier gate: runs per-selected-project test baseline before
  verifying the merged artifact, then asserts the monolith test count is not
  lower than the baseline sum.
- `mode: :components` is accepted as an alias for `:package_projection` for
  compatibility with earlier internal configurations.

### Changed

- Package-projection verifier now runs `deps.compile` then
  `compile --warnings-as-errors --no-compile-deps` instead of a single
  `compile --warnings-as-errors` step.
- Manifest dependency validation: `:path` is still rejected; `:git` and
  `:github` are now permitted in dependency opts.
- Canonical external dep normalization strips `:override`, `:branch`, `:tag`,
  `:ref`, and `:subdir` from workspace dep opts before merging manifest opts.
- Monolith artifacts are excluded from `hex.publish --dry-run --yes` during
  verification (not a publishable Hex package in the traditional sense).
