# 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).

## [0.3.0] - 2026-04-08

### Added

- `monolith_opts[:test_support_projects]`, an explicit manifest-owned contract
  for non-selected workspace projects that still participate in the monolith
  `:test` view as source-only support.

### Changed

- Monolith projection now fails closed when
  `monolith_opts[:test_support_projects]` is declared but the discovered
  non-selected test support set does not match the manifest.
- Monolith config bootstrap app ownership is now derived from staged bootstrap
  sources rather than from every staged project app, which keeps generated
  application bootstrap allowlists aligned with the actual runtime config
  surface.
- Consumer integration docs, monolith docs, and examples now describe the
  explicit source-only test support policy.

### Fixed

- `guides/consumer_repo_integration.md` now references the current Weld
  dependency line instead of an outdated `0.1.0` example.

## [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).

## [0.1.0] - 2026-04-02
