+# Add mcpplibs.mwrap.dr_libs (dr_libs-m 2026.03.03)
+
+## Form
+
+- Third-party upstream [mackron/dr_libs](https://github.com/mackron/dr_libs), a choice of Unlicense or MIT-0. Upstream
+  tags each header on its own; compat.dr_libs 2026.03.03 (the parent change) pins the commit archive of `wav-0.14.5`
+  (fa931f3, `b56be593…bb7e`), whose `dr_flac.h` and `dr_mp3.h` are byte-identical to `flac-0.13.3` and `mp3-0.7.3`.
+- Form A external mwrap module repository [mcpplibs/dr_libs-m](https://github.com/mcpplibs/dr_libs-m), package
+  `mcpplibs.mwrap.dr_libs`, version 2026.03.03 (compat.dr_libs' date version; the three header versions and the commit
+  in `[package.metadata.mwrap]`), tag series `mwrap-${version}`, tagged on the merged main commit (0d4c72e); release
+  asset `dr_libs-m-2026.03.03.tar.gz` (`0dc7ac0e…dbe2`), CN mirror `gitcode.com/mcpp-res/mwrap-dr_libs` with identical
+  bytes.
+- One package, as compat.nanosvg packages its two stb-style headers: the three headers share one commit and one
+  implementation TU, and a program using one usually uses another (miniaudio embeds all three). Each header is still
+  its own module.
+- Implementation ownership: the library is compat.dr_libs'. The wrapper vendors no upstream code; it retains
+  upstream's README.md and LICENSE under `upstream/dr_libs/` (checksums in `upstream/documents.json`) and deploys them
+  with its own LICENSE/NOTICE (`runtime.deploy`).
+
+## Modules
+
+- `mcpplibs.mwrap.dr_libs.wav` / `.flac` / `.mp3`: every type, enumerator and `*_API` function of the header's public
+  part by `export using` (wav 42 / 48 / 94, flac 32 / 6 / 31, mp3 28 / 8 / 29), generated from the pinned headers; each
+  re-exports `.macros` and is complete on its own. Every enum is named by its typedef, so the enumerators have linkage
+  and are exported as they are. The root `mcpplibs.mwrap.dr_libs` re-exports all four.
+- `mcpplibs.mwrap.dr_libs.macros`: the 171 object-like macros as `inline constexpr` of the type of their expansion (the
+  version strings as references to constexpr char arrays). The headers define no computation macro.
+- Stay macros, in `<mwrap/dr_libs/macros.hpp>` (= the three headers): `*_API`, `*_PRIVATE`, `*_DLL_*`,
+  `DRFLAC_DEPRECATED`, `DRMP3_INLINE`, `DRMP3_GNUC_INLINE_HINT`, `*_STRINGIFY` / `*_XSTRINGIFY`, `DRFLAC_64BIT`,
+  `DRFLAC_X64`, `DRFLAC_X86`, `DRFLAC_ARM` (28). Not mapped: the 3 include guards.
+
+`tools/check_exports.py` fails when the generated sources are stale, a declaration is not exported by its submodule, or
+a macro is neither mapped nor listed; every mapping is checked against the raw header in a header-mixing test.
+
+## Verification
+
+Wrapper CI (Linux x86_64 GCC 16.1 and LLVM 23.1.3, Linux arm64 GCC 16.1, macOS LLVM, Windows LLVM, all required): build,
+eight test programs (the API through the module — WAV round trips in RIFF / Wave64 / RF64, IEEE float, A-law, mu-law,
+a hand-written AIFF, cue metadata, narrow and wide paths; a FLAC fixture sample-exact against the signal of its
+STREAMINFO MD5; an MP3 fixture to its LAME-gapless length; each submodule alone; the macros against the headers; header
+mixing; compat.miniaudio in the same program decoding the fixtures to identical samples), the export audit, and the
+example tool on the fixtures. The templates job scaffolds the default `tone` template as an installed package and runs
+it. Until compat.dr_libs is on this index's main, the wrapper's CI resolves the compat namespace from the parent
+change's branch (`tools/candidate_index.py`, a no-op once published).
+
+Here, with the CI-pinned mcpp 2026.10.26.1:
+
+- `bash tests/run_members.sh dr_libs-audio`: the real release archive through the candidate index; a WAV written and
+  read back, a FLAC stream built in the test (CONSTANT subframes, CRC-8/16) decoded and seeked, the MP3 to 4410 frames
+  with its 440 Hz tone, the `.flac` module alone, and the side header beside the import: `test result ok`.
+- `python3 tests/mwrap/check_installed_template.py --package mcpplibs.mwrap.dr_libs@2026.03.03 --deploy`: the
+  unmodified template from the real archive, then a relocated self-contained bundle whose `licenses/dr_libs/` holds the
+  wrapper's LICENSE/NOTICE and dr_libs' README and LICENSE byte for byte.
+
+## Motivation
+
+openmui's coming audio engine (media.audio) decodes WAV, FLAC and MP3 assets; these permissively licensed decoders,
+through modules, fit its statically linked framework, beside miniaudio for playback.

 ### Added
 
+- **mcpplibs.mwrap.dr_libs 2026.03.03(新包)。** dr_libs-m:以 C++23 模块(`import mcpplibs.mwrap.dr_libs;`)使用
+  compat.dr_libs 2026.03.03(dr_wav 0.14.5、dr_flac 0.13.3、dr_mp3 0.7.3)。每个头文件各一个模块且可单独导入:
+  `mcpplibs.mwrap.dr_libs.wav`(42 个类型、48 个枚举值、94 个函数)、`.flac`(32、6、31)、`.mp3`(28、8、29),全部以
+  `export using` 导出上游全局名;每个枚举都由 typedef 命名,枚举值按原样导出。`mcpplibs.mwrap.dr_libs.macros` 把 171 个
+  对象式宏映射为其自身类型的常量;`*_API` 等属性、字符串化宏与 dr_flac 的平台检测宏共 28 个留在
+  `<mwrap/dr_libs/macros.hpp>`。包装仓库的 CI(Linux x86_64 GCC/LLVM、Linux arm64、macOS、Windows)逐样本核对 FLAC
+  解码、按 LAME 标签的无缝长度解码 MP3、在各容器中往返 WAV,并与 compat.miniaudio 链接在同一程序中解码出相同样本。
+  GLOBAL 为 `mwrap-2026.03.03` 发布资产,CN 为 GitCode `mcpp-res/mwrap-dr_libs` 镜像,sha256 一致。新增测试成员
+  `tests/mwrap/dr_libs-audio` 与已安装模板及其许可文件的部署检查。
