-## 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
 
+## [0.8.2] - 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.
+
+**Изменено:**
+
+- **CLI host triple больше не форсится** — без `--target` используется `build.target` пакета/member (важно для bare-metal / post_steps ISO).
+- **Relative `-I`/`-L`/`-T` (и `-isystem`/`-idirafter`)** в cflags/ldflags абсолютизируются относительно корня пакета (workspace CWD = root).
+- **`dcr clean --all`** — не спамит `target not found` по members без локального `target/` (общий root `target/`).
+- **`error` / `warn`** — красный / жёлтый, вывод на stderr; `Подсказка:` → `Hint:`.
+- **`dcr --help` / man** — добавлены `add`, `lint`, `setup`; unknown command → exit code 1.
+- **Сообщения NotFound** — `linker not found: ld.lld …` / `{tool} not found …` вместо сырого `os error 2`.
+
+### EN
+
+**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
 
+## 0.8.2 (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`.

-- **`[archive]` section** — after a successful build, pack a FAT disk image (`fatfs`): `output`, `format` (`fat12`/`fat16`/`fat32`), optional `size` (default 1.44 MiB), `offset`, `label`, `bootsector`, and `layout` (`from` → `to`, supports globs). `{profile}` works in paths.
+- **`[archive]` section** — FAT12/16/32 disk images after build (`output`, `format`, `size`, `offset`, `label`, `bootsector`, `layout`). From 0.8.2 requires feature `archive`.
