 ## Unreleased
 
-## 1.0.0 - 2026-06-17
+### Added
+
+- `mac` command-line interface with a modular, auto-discovered command
+  architecture (setup, doctor, update, uninstall) and dynamic help built from a
+  command registry.
+- Official `install.sh` bootstrap that clones the repository, manages the `mac`
+  symlink, and safely manages the shell PATH block.
+- Self-update mechanism (`mac update`) using a temporary worktree and
+  fast-forward-only updates with rollback.
+- Full uninstall command (`mac uninstall`) with `--remove-config` and
+  `--remove-install-dir`, removing only managed files that match the versioned
+  copies (now covering all managed Zsh dotfiles).
+- Setup profiles system (`full` and `minimal`) with profile-aware Brewfiles and
+  dynamic profile validation.
+- Generated Zsh completion for `mac`, built from the command registry and
+  verified in CI.
+- Structured logging helpers and unified error handling across the CLI.
+- CLI smoke tests (`npm test`) and commit linting through commitlint.
+
+### Changed
+
+- Homebrew setup split into profile Brewfiles; the root `Brewfile` is now a
+  compatibility symlink to `profiles/full/Brewfile`.
+- Git configuration relies solely on the managed `include.path`, with no direct
+  writes to the global config.
+- macOS CI consolidated into a single gate, and commits are linted with
+  commitlint across the pull request range.
+- `mac setup` writes its log to a user-level location instead of the current
+  working directory.
+
+### Fixed
+
+- `mac setup --help` and `mac doctor --help` print usage instead of failing or
+  silently running diagnostics.
+- `mac doctor` exits non-zero when a required tool is missing.
+- Setup no longer regenerates the versioned completion file and no longer fails
+  when completion is not yet active in the current shell.
+
+## 0.4.1 - 2026-06-17
+
+### Added
+
+- macOS bootstrap system with split Brewfiles and validation scripts.
+- Fast, optimized CI pipeline.
+- Standardized gitmoji commit conventions with commitlint and husky.

+# Current architecture
+
+MacDevSetup is organized around a small shell CLI and a profile-based package
+inventory.
+
+## Entry points
+
+- `install.sh` installs or updates the checkout and creates the `mac` symlink.
+- `scripts/cli.sh` dispatches `mac` commands.
+- `scripts/commands/` contains the public command implementations.
+- `scripts/setup.sh` is the internal setup runner used by `mac setup`.
+
+## Package profiles
+
+Homebrew packages are declared under `profiles/<name>/Brewfile`.
+
+- `profiles/minimal/Brewfile` contains the smaller command-line setup.
+- `profiles/full/Brewfile` contains the complete curated workstation setup.
+- The root `Brewfile` links to `profiles/full/Brewfile` for compatibility with
+  common `brew bundle --file=Brewfile` workflows.
+
+Profile names are validated in `scripts/lib/profiles.sh`.
+
+## Managed user files
+
+`mac setup` may install versioned Git and Zsh configuration.
+
+Zsh files are copied from `configs/zsh/` to the user's home directory. Existing
+files are backed up first when their content differs from the versioned files.
+
+Git is configured through a global `include.path` entry that points at
+`configs/git/.gitconfig`. Other global includes are left untouched.
+
+## Generated files
+
+`configs/zsh/completions/_mac` is generated from the command registry by
+`scripts/generate-zsh-completion.sh`.
+
+The CI workflow checks that the committed completion file is up to date.
+
+## Quality gates
+
+Local and CI validation are centered on:
+
+- `npm test` for quick CLI smoke tests;
+- `pre-commit run --all-files` for formatting, markdown, links, secrets, and
+  workflow linting;
+- macOS workflows for Homebrew and setup validation.
