-
-## Quick start
-
-```bash
-cargo build --release && ./target/release/dcr setup
-```
-
-## Pre-PR (CI) gate
-
-```bash
-cargo fmt --all --check
-cargo clippy --all-targets --all-features -- -D warnings
-cargo check --all-targets --all-features
-cargo test
-```
-
-CI (`.github/workflows/ci.yml`) runs fmt, clippy, check — **not** tests.
-
-## Tests
-
- Integration tests in `tests/` build the dcr binary and run it in temp dirs under `sandbox/cli-tests/` (gitignored).
- Some tests **skip** if no C compiler (`gcc`/`clang`/`cc`) is found at runtime.
- Compiler can be overridden via `DCR_COMPILER` or `DCR_CC` env vars.
- Tests use `$CARGO_BIN_EXE_dcr` when available, else `target/debug/dcr`.
-
-## Architecture
-
- **Single Rust package** (edition 2024), not a workspace. Only one binary: `dcr`.
- **Entrypoint**: `src/main.rs` — matches `args[1]` against command names.
- **Compiler backends** in `src/core/builder/`: `unix_cc` (gcc/clang), `msvc` (cl/clang-cl), `gas`, `nasm`. Dispatched by matching compiler name string.
- **Config**: `dcr.toml` (per-project), `~/.dcr/config.toml` (registry), `~/.dcr/index.json` (index). Defaults: `language=c`, `standard=c11`, `compiler=clang`, `kind=bin`.
- **`build.rs`** embeds `TARGET` as `DCR_TARGET` env var (shown in `--version`).
- **CLI output** must be in English. Use `utils::log` for messaging.
-
-## Key commands
-
-| Command | Notes |
-|---|---|
-| `dcr new <name>` | Creates project dir |
-| `dcr init` | Init from CWD (must be empty) |
-| `dcr build [--debug\|--release] [--target <triple>]` | Default profile: `--debug` |
-| `dcr run [--debug\|--release]` | Only for `kind = "bin"` |
-| `dcr clean [--debug\|--release] [--all]` | `--all` for workspace roots |
-| `dcr tree` | Dependency tree viewer |
-| `dcr test [--init]` | Runs/test project tests |
-| `dcr gen <vscode\|clion\|compile-commands>` | IDE integration |
-| `dcr --update` | Self-update from GitHub Releases |
-
-## Cross-compilation
-
-`--target` accepts short names (`linux`, `macos`, `windows`) or full triples. In CI, Linux cross-builds use `cargo-zigbuild`. When `build.target` is set in `dcr.toml`, DCR auto-injects `--target=<value>` into cflags (clang). Bare-metal targets (containing `none`/`-elf`/`eabi`/`baremetal`) skip DCR's default compiler flags.
-
-## Dependencies (Cargo)
-
-reqwest (blocking+json+rustls-tls), serde, toml, git2, openssl (vendored), self-replace, sha2, ctrlc.

 # Changelog

+## [0.8.4] - 2026-08-04 "Инфраструктура .dcr/ и интеграция с IDE / Internal .dcr/ Layout & IDE Integration"
+
+### RU
+
+**Добавлено:**
+
+- **Директория `.dcr/`** — единый machine-readable источник фактов о сборке для IDE/расширений:
+  - `.dcr/compile_commands.json`
+  - `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
+  - `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
+  - `.dcr/ide/` (заготовки lock-файлов для расширений)
+- **`dcr gen project-info`** — поля `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; пути абсолютные/канонические.
+- **`dcr build --print-artifact-path`** — после успешной сборки одна строка absolute path на stdout.
+- **`dcr gen … --quiet` / `-q`** — без human-лога на stdout для `compile-commands` / `project-info`.
+- **`.clangd`** — при первом `gen` создаётся с `CompilationDatabase: .dcr` (маркер `# managed by dcr gen`); ручной `.clangd` не перезаписывается.
+- **Хелперы** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` через `platform::*`.
+- **`dcr new` / `dcr init`** — `.dcr/` в `.gitignore`.
+
+**Изменено (breaking):**
+
+- **`compile_commands.json` перенесён** из корня проекта в **`.dcr/compile_commands.json`**.  
+  clangd находит базу через `.clangd` / `clangd.arguments --compile-commands-dir=.dcr`.  
+  CLion `misc.xml` и VSCode `settings.json` обновлены под новый путь.
+- **Атомарная запись** `compile_commands.json` (tmp + rename).
+- **`gen vscode` / `gen clion` launch/run** — `program`/`executable` через тот же artifact resolver, что `project-info` / `build-info.json` (Linux triple, Windows `.exe`, custom `target`/`filename`).
+
+**Исправлено:**
+
+- Launch-конфиги больше не указывают `target/<profile>/<name>` без triple на Linux.
+- Симлинки/mount: root и пути в compile database канонизируются best-effort.
+
+### EN
+
+**Added:**
+
+- **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
+  - `.dcr/compile_commands.json`
+  - `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
+  - `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
+  - `.dcr/ide/` (placeholder for IDE lock files)
+- **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
+- **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
+- **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
+- **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
+- **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
+- **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
+
+**Changed (breaking):**
+
+- **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.  
+  clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.  
+  CLion and VSCode generators updated accordingly.
+- **Atomic write** for compile_commands (tmp + rename).
+- **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
+
+**Fixed:**
+
+- Launch configs no longer hardcode `target/<profile>/<name>` without the Linux triple segment.
+- Symlink/mount roots: best-effort canonicalize for root and compile database paths.
+
+## [0.8.3] - 2026-08-03 "Конфигурация host target, аргументы run и нативные пути артефактов / Host Target Config, Run Args & Native Artifact Paths"
+
+### RU
+
+**Добавлено:**
+
+- **`dcr run -- <args>...`** — cargo-style: всё после bare `--` передаётся собранному бинарнику  
+  (`dcr run --release -- --test_help`). Работает и для прямого запуска, и для `[run].cmd`.
+- **Интеграционные / unit-тесты** — host target sections применяют `ldflags` без `--target`; проброс аргументов после `--`; парсер `split_double_dash`.
+
+**Изменено:**
+
+- **Native-сборка резолвит host triple** — без `--target` / без `build.target` конфиг-секции вида  
+  `[build.x86_64-unknown-linux-gnu]` (и аналоги host) снова применяются (`cflags` / `ldflags` / toolchain).  
+  Раньше target был «пустым», секции молча игнорировались, а артефакты уже лежали под host triple — линковка без `-L`/`-l`.
+- **Пустой target** — `normalize_target_os("")` больше не warn'ит `Unknown target ''`.
+- **`dcr run --help` / man `dcr-run`** — документирован разделитель `--` и forwarding args.
+
+**Исправлено:**
+
+- **Нативные пути артефактов на Windows и macOS** — без явного `--target` / `build.target` артефакты снова сохраняются в `target/<profile>`, поэтому `dcr run` и flat-bin находят результат сборки.
+- Target-specific `ldflags` на native Linux/macOS/Windows (host triple) не доходили до линкера.
+- Ложный warning на пустой target string.
+
+### EN
+
+**Added:**
+
+- **`dcr run -- <args>...`** — cargo-style: arguments after a bare `--` are forwarded to the built binary  
+  (`dcr run --release -- --test_help`). Works for direct binary runs and `[run].cmd`.
+- **Tests** — host target sections apply `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
+
+**Changed:**
+
+- **Native builds resolve the host triple** — without `--target` / without package `build.target`, host sections such as  
+  `[build.x86_64-unknown-linux-gnu]` (and host equivalents) apply again (`cflags` / `ldflags` / toolchain).  
+  Previously the target was empty, those sections were silently ignored while artifacts already used the host triple path — link failed without `-L`/`-l` (e.g. sandbox micro-lang + `libsct-elf`).
+- **Empty target** — `normalize_target_os("")` no longer warns `Unknown target ''`.
+- **`dcr run --help` / man `dcr-run`** — document `--` and argument forwarding.
+
+**Fixed:**
+
+- **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts again use `target/<profile>`, so `dcr run` and flat-bin find the build output.
+- Target-specific `ldflags` on native host builds not reaching the linker.
+- Spurious warning for an empty target string.
+
+## [0.8.2] - 2026-07-22 "CLI Progress, archive Feature, Workspace Path Fixes / CLI Progress, archive Feature, Workspace Path Fixes"
+
+### RU
+
+**Добавлено:**
+
+- **Прогресс компиляции `[N/M]`** — live-строка `compile  pkg v0.1.0  [12/41]` на TTY (stderr), чтобы длинные mono-package сборки не выглядели «зависшими».
+- **Свой стиль статуса build** — фиксированная колонка глаголов: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run` (не cargo-clone).
+- **Cargo feature `archive`** — `fatfs` и упаковка FAT-образов опциональны (`cargo build --features archive`). Release CI собирает с feature; без feature `[archive]` даёт явную ошибку.
+- **Интеграционные тесты** — `flat_bin_nasm_build`, `package_build_target_used_without_cli_flag`, усилен workspace `clean --all`.
+- **Расширенный CI** — unit + integration на Linux/macOS/Windows, отдельный job с `--features archive`, rust-cache, clippy default + all-features.
+

+**Added:**
+
+- **Compile progress `[N/M]`** — live TTY line `compile  pkg v0.1.0  [12/41]` so long mono-package builds do not look hung.
+- **DCR status verbs** — fixed-width column: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
+- **Cargo feature `archive`** — optional `fatfs` / FAT packing (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` errors clearly.
+- **Integration tests** — `flat_bin_nasm_build`, package `build.target` without CLI flag, stricter workspace `clean --all`.
+- **Expanded CI** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features.
+
+**Changed:**
+
+- **CLI no longer forces host triple** — without `--target`, package/member `build.target` is used (bare-metal / ISO post_steps).
+- **Relative `-I`/`-L`/`-T` (and `-isystem`/`-idirafter`)** in flags are absolutized against the package root when workspace CWD is the root.
+- **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
+- **`error` / `warn`** — red / yellow on stderr; Russian `Подсказка:` → `Hint:`.
+- **`dcr --help` / man** — list `add`, `lint`, `setup`; unknown command exits 1.
+- **NotFound messages** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.

-# DCR TODO.md
-
-Priority list of tasks to turn DCR into a true Cargo killer for C/C++ developers.
-
-**Legend:** `[ ]` — not implemented | `[-]` — partially implemented | `[x]` — implemented
-
-## 🔥 High Priority
-
- [ ] **CLI Output Refactoring & Cleanup**
-  - [ ] Move all terminal strings to a dedicated module (`src/ui/messages.rs`)
-  - [ ] Standardize logging formats (`error:`, `warning:`, `status:`)
-  - [x] Add build execution time statistics to the final output (e.g., `Finished in 4.23s`)
- [ ] **Internationalization (i18n) / Localization**
-  - [ ] Integrate a lightweight localization engine (`fluent` or `gettext` pure-Rust port)
-  - [ ] Create initial translation catalogs (`en.ftl`, `ru.ftl`)
- [x] **Self-Update Stability Validation**
-  - [x] Self-update implemented via `self-replace` + `ureq` in `flag_update.rs`
- [-] **Freestanding / Embedded Automation**
-  - *`-ffreestanding` injected at compile time, `-nostdlib -static` at link time for bare-metal targets or `build.freestanding = true`. Config option `build.freestanding` (bool) added.*
- [ ] **Conan and vcpkg integration** Automatic download, installation and linking of packages
-
-## ✅ Medium Priority
-
- [ ] **Static analysis** (`dcr check`)  
-  Integration with clang-tidy, cppcheck, include-what-you-use
- [x] **Linter + Formatter** (`dcr fmt`, `dcr lint`)  
-  *`dcr fmt` (clang-format) and `dcr lint` (clang-tidy) are implemented*
- [ ] **Hot reload / Live reload** for applications (raylib, SFML, SDL, etc.)
- [-] **Workspaces improvements** Per-member include directories, selective builds, better dependency graph  
-  *Basic workspaces with dep ordering + topological sort work; advanced features missing*
- [-] **Build-time code generation** Support for protobuf, flatbuffers, Qt moc, custom generators  
-  *Generic `build.steps` machinery + Qt toolchain (uic/moc/rcc) work; no dedicated protobuf/flatbuffers generators*
- [-] **dcr publish + official package registry** *Registry consumption (fetch, resolve, link) works; `dcr publish` command / local packing missing*
-
-## 📌 Low Priority / Nice to Have
-
- [ ] Support for Meson and Ninja as alternative backends
- [ ] Dockerfile generation (`dcr docker init`)
- [ ] First-class Windows MSVC support (currently works but rough)
- [ ] Documentation generation (`dcr doc`)
- [ ] Sanitizers integration (`dcr sanitize`)
- [ ] Benchmarks and comparison with CMake/Meson
- [ ] C++20 modules support (when it becomes stable)
-
-## 🧠 Future Ideas
-
- Official DCR package registry (dcrhub)
- GUI wrapper (dcr-gui)
- Plugin system
- Toolchain manager (like rustup)
- Zig as alternative compiler
- deb/rpm/flatpak/AppImage packaging support
-
---
-
-**Currently in progress:**
- UI/UX terminal output unification and benchmarking metrics.
-
-**Completed in recent releases:**
- Extreme binary size optimization (-50% weight reduction via `ureq` + `native-certs`)
- Complete removal of `git2` and `openssl` in favor of system Git execution
- Workspaces & Cross-compilation (`--target <triple>`)
- IDE config generation (VS Code, CLion, compile_commands.json)
- EFI support & Linker script support (`build.ldscript`)
- Mixed C/C++/ASM compilation with custom `std::thread::scope` work-stealing engine

 # Changelog

+## 0.8.4 (2026-08-04)
+
+**Added:**
+
+- **`.dcr/` directory** — shared machine-readable build facts for IDE integrations:
+  - `.dcr/compile_commands.json`
+  - `.dcr/build-info.json` (`schemaVersion`, `artifact_path`, `profile`, …)
+  - `.dcr/toolchain.json` (compiler/debugger paths, moc/uic/rcc)
+  - `.dcr/ide/` (placeholder for IDE lock files)
+- **`dcr gen project-info`** — `target`, `target_dir`, `artifact_path`, `artifact_kind`, `source_roots`, `include_globs`, `exclude_globs`; absolute/canonical paths.
+- **`dcr build --print-artifact-path`** — one absolute artifact path line on stdout after a successful build.
+- **`dcr gen … --quiet` / `-q`** — suppress human success logs for gen subcommands.
+- **`.clangd`** — created on first gen with `CompilationDatabase: .dcr` (`# managed by dcr gen`); custom `.clangd` is not overwritten.
+- **Helpers** `canonicalize_path`, `atomic_write`, `ensure_dcr_dir`; pure `resolve_artifact_path` via `platform::*`.
+- **`dcr new` / `dcr init`** — add `.dcr/` to `.gitignore`.
+
+**Changed (breaking):**
+
+- **`compile_commands.json` moved** from project root to **`.dcr/compile_commands.json`**.  
+  clangd discovers it via `.clangd` / `--compile-commands-dir=.dcr`.  
+  CLion and VSCode generators updated accordingly.
+- **Atomic write** for compile_commands (tmp + rename).
+- **`gen vscode` / `gen clion` launch/run** — use the same artifact path resolver as `project-info` / `build-info.json`.
+
+**Fixed:**
+
+- Launch configs no longer hardcode `target/<profile>/<name>` without the Linux triple segment.
+- Symlink/mount roots: best-effort canonicalize for root and compile database paths.
+
+## 0.8.3 (2026-08-03)
+
+### Added
+
+- **`dcr run -- <args>...`** — cargo-style argument forwarding after a bare `--`  
+  (`dcr run --release -- --test_help`). Applies to direct binary runs and `[run].cmd`.
+- **Tests** — host target section `ldflags` without CLI `--target`; run-arg forwarding; `split_double_dash` unit tests.
+
+### Changed
+
+- **Native builds resolve the host triple** — without `--target` / package `build.target`, host sections such as  
+  `[build.x86_64-unknown-linux-gnu]` apply again (`cflags` / `ldflags` / toolchain).  
+  Previously the target was empty and those sections were ignored while artifacts already used the host triple path.
+- **Empty target** — no more `Unknown target ''` warning.
+- **`dcr run --help` / man `dcr-run`** — document `--` forwarding.
+
+### Fixed
+
+- **Native artifact paths on Windows and macOS** — without an explicit `--target` / `build.target`, artifacts use `target/<profile>`, so `dcr run` and flat-bin find the build output.
+- Target-specific `ldflags` missing on native host builds (e.g. micro-lang + `libsct-elf`).
+- Spurious empty-target warning.
+
+## 0.8.2 (2026-07-22)
+
+### Added
+
+- **Compile progress `[N/M]`** — live TTY status line (`compile  pkg v0.1.0  [12/41]`) so long mono-package builds do not look hung.
+- **DCR status style** — fixed-width verbs: `project`, `compile`, `dep`, `ready`, `pack`, `done`, `run`.
+- **Cargo feature `archive`** — optional FAT packing via `fatfs` (`cargo build --features archive`). Release CI builds with the feature; without it `[archive]` fails with a clear message.
+- **Tests** — `flat_bin_nasm_build`, package `build.target` without CLI `--target`, stricter workspace `clean --all`.
+- **CI expansion** — unit + integration on Linux/macOS/Windows, archive feature job, rust-cache, clippy default + all-features (see `.github/workflows/ci.yml`).
+
+### Changed
+
+- **No forced host triple from CLI** — without `--target`, package/member `build.target` is honored (bare-metal / ISO `post_steps` paths).
+- **Relative include/lib flags** (`-I`, `-i`, `-isystem`, `-idirafter`, `-L`, `-T`) absolutized against the package root under workspace builds.
+- **`dcr clean --all`** — no spam for members without a local `target/` (shared root `target/`).
+- **`error` / `warn`** — red / yellow on stderr; CLI fully English (`Hint:`).
+- **Help / man** — list `add`, `lint`, `setup`; unknown command exits with code 1.
+- **Tool NotFound** — `linker not found: ld.lld …` / `{tool} not found …` instead of raw `os error 2`.

 # Installation

-## Linux (Dexoron Packages)
+## dcrup (recommended)

-Configure your package manager at https://pkg.dexoron.su and install:
+Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
+
+### Linux / macOS / BSD / Windows (bash)

-**Arch Linux**
 ```sh
-sudo pacman -Sy dcr
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
+export PATH="$HOME/.dcr/bin:$PATH"
+dcrup install stable
 ```

-**Debian/Ubuntu**
+Non-interactive install of DCR in one shot:
+
 ```sh
-sudo apt update && sudo apt install dcr
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
+export PATH="$HOME/.dcr/bin:$PATH"
 ```

-**Fedora/RHEL**
-```sh
-sudo dnf install dcr
+### Windows (PowerShell)
+
+```powershell
+irm https://ps1.dcr-tool.ru | iex
+# or download then run:
+# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
+# powershell -File .\dcrup.ps1 self-install
+# $env:Path += ";$env:USERPROFILE\.dcr\bin"
+dcrup install stable
 ```

+Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
+
+```bat
+curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
+```
+
+After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
+
+### Common dcrup commands
+
+```sh
+dcrup install stable              # latest stable prebuilt
+dcrup install 0.8.2               # pin → 0.8.2@stable
+dcrup install 0.8.2@dev
