+## [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.

 **Добавлено:**

 **Исправлено:**
+
 - **Сборка на macOS Apple Silicon падала с `_main` undefined** — `--target=` теперь передаётся и в ldflags, не только в cflags. `default_target_triple()` на macOS использует `std::env::consts::ARCH` вместо хардкода `x86_64`.

 **Added:**

 - **macOS Apple Silicon builds failed with `_main` undefined** — `--target=` is now passed to ldflags, not just cflags. `default_target_triple()` uses `std::env::consts::ARCH` on macOS instead of hardcoded `x86_64`.
 - **GitHub Stars and GPL-3.0 badges not rendering in README** — badge block converted to pure HTML.
