+# Add Galay 5.0.0 (`gzj-creator.galay`)
+
+Date: 2026-08-29
+Upstream: <https://github.com/gzj-creator/galay>
+Tag: `v5.0.0` (`a9e81ce8239695a8dae68314ee991339839d5409`)
+Status: local Linux validation passed with mcpp 2026.8.27.1 and the CI-pinned 2026.8.27.2 check.
+
+## 1. Shape and identity
+
+Galay is source type (b), a library already developed for mcpp. Its v5.0.0
+release carries a complete `mcpp.toml`, so the index entry is Form A and does
+not duplicate its build recipe.
+
+- Package identity: `namespace = "gzj-creator"`, `name = "galay"`. The
+  namespace names the upstream owner; the package name remains one atomic
+  segment.
+- The upstream manifest builds the default `galay.utils` and `galay.kernel`
+  named modules plus their C++ implementations. SSL, HTTP, WebSocket, HTTP/2,
+  database, RPC, MCP, and tracing sources remain opt-in features in that
+  manifest, with the corresponding feature dependencies preserved.
+- The release manifest declares `platforms = ["linux", "macos"]`. The index
+  therefore publishes `linux` and `macosx` entries only; Windows is omitted
+  until the upstream manifest gains a Windows-compatible build.
+- License and description are taken from the upstream manifest: Apache-2.0,
+  C++23 coroutine networking and protocol framework.
+
+## 2. Source and hash
+
+Both platform entries use the immutable GitHub tag archive:
+
+    https://github.com/gzj-creator/galay/archive/refs/tags/v5.0.0.tar.gz
+
+The archive is 5,227,585 bytes. `sha256sum` was run twice on the complete
+archive and returned:
+
+    8e410d97b0615333c92192633f9495acdc8eb1d56dd94f1eeecd8e68e5a4f73e
+
+`tar -tzf` succeeds and confirms the root `mcpp.toml`, the tracked include
+layout, and the fifteen named C++23 module interfaces are present.
+
+## 3. CN mirror
+
+`gtc` is not installed in this environment and no GitCode write credential is
+available. Following `docs/cn-mirror.md`, the descriptor uses the plain GLOBAL
+URL rather than inventing a mirror table. CN consumers fall back to GitHub;
+the `mcpp-res/galay` mirror can be added later without changing the package
+identity or version.
+
+## 4. Workspace member
+
+`tests/examples/galay` is a Unix-gated public-package consumer. Its member
+manifest has exactly one project index redirect:
+
+    [indices]
+    gzj-creator = { path = "../../.." }
+
+The test imports `galay.utils` and `galay.kernel`, checks Base64 and string
+helpers, links the out-of-line `kernel::Buffer` implementation, and validates
+IPv4 `kernel::Host` construction. Windows compiles a no-op `main()` because
+the upstream package has no Windows platform entry.
+
+The first RED run failed as expected before the descriptor existed:
+
+    error: dependency 'gzj-creator.galay': no package found for exact selector
+
+After adding the descriptor, the first executable run caught an incorrect
+assumption about `Buffer::clear()` retaining its length; the assertion was
+changed to require the documented empty state. The corrected test then passed.
+
+## 5. Validation
+
+- `mcpp xpkg parse pkgs/g/gzj-creator.galay.lua` passed with the Form-A result
+  and Linux/macOS version lists.
+- `mcpp test -p galay` passed with mcpp 2026.8.27.1 after a cold build:
+  `test result ok. 1 passed; 0 failed`.
+- The CI-pinned `mcpp 2026.8.27.2` test also passed offline:
+  `test result ok. 1 passed; 0 failed`.
+- The build compiled 26 Galay units, including both default module interfaces,
+  the kernel implementation units, and the transitive libaio package.
+- All six descriptor lint checks passed, and all 134 package descriptors passed
+  `mcpp xpkg parse` with the CI-pinned binary.
+- Optional Galay features are intentionally not enabled by this minimal
+  member. They remain upstream-owned feature/dependency decisions and need
+  dedicated protocol/database environments before being advertised as tested.
+
+## 6. Follow-up
+
+When upstream publishes Windows support or a maintainer creates the
+`mcpp-res/galay` release asset, add the platform/mirror entry with the same
+archive bytes and keep the version at `5.0.0` only if the bytes remain
+identical; otherwise publish a new upstream version/tag.

It vendors only gRPC's own source and takes the five dependencies from this index, so a consumer that also uses protobuf links one copy rather than two) |
+| Native multi-module library with feature-scoped sources | [`gzj-creator.galay`](../pkgs/g/gzj-creator.galay.lua) (Galay 5.0.0 — the upstream Form-A manifest exposes `galay.utils` and `galay.kernel` by default, while SSL, HTTP, database, RPC, MCP, and tracing modules stay behind named features and their corresponding dependencies. The index keeps the upstream manifest intact and tests the default module surface on Unix.) |
 | C-source compat (with `features`) | [`compat.cjson`](../pkgs/c/compat.cjson.lua) · [`compat.zlib`](../pkgs/c/compat.zlib.lua) · [`compat.hiredis`](../pkgs/c/compat.hiredis.lua) (the classic 1.2.0 — a 7-TU C build whose flat tarball headers get `hiredis/`-prefixed wrapper headers via `generated_files`, so consumers write `#include <hiredis/hiredis.h>` exactly like upstream's install layout) · [`compat.sqlite3`](../pkgs/c/compat.sqlite3.lua) (plain C-source, no features: the single `sqlite3.c` amalgamation; 3.45.3, the final maintenance release of the most widely deployed 3.45.x line) · [`compat.libuv`](../pkgs/c/compat.libuv.lua) (libuv 1.48.0 — the per-OS source sets transcribed from upstream's CMakeLists, because a `src/unix/*.c` glob would compile every OS's backend at once; linux/macos get explicit unix subsets, windows globs `src/win/*.c`) | · [`compat.xxhash`](../pkgs/c/compat.xxhash.lua) (one TU, one header, no features at all — the interesting decision is what is NOT compiled: `xxh_x86dispatch.c` selects an AVX2/AVX512 path at RUNTIME and needs per-file `-mavx2` plus `XXH_X86DISPATCH` at every call site, so the package ships the flagless SSE2 baseline instead. Nor is the header-only `XXH_INLINE_ALL` mode chosen: it re-emits the implementation in every TU that hashes anything, which is the right trade only when there is exactly one such TU — something a package cannot know)
 | C-source compat where the library IS a kernel ABI | [`compat.libaio`](../pkgs/c/compat.libaio.lua) (libaio 0.3.113 — twelve syscall-wrapper TUs, and the only `xpm` section is `linux`, because there is no port to declare: `struct iocb` is the kernel's and every TU is `syscall(__NR_io_*, …)`. Consumers gate it with `[target.'cfg(linux)'.dependencies]`, the mirror image of compat.wil. Three things it teaches. **One public header out of a source dir**: upstream installs exactly one, `libaio.h`, but the tarball keeps it in `src/` beside the private headers — one of which is named `syscall.h` and would SHADOW glibc's for every consumer TU — so `include_dirs` names a `generated_files` forwarder and nothing else; the package's own sources reach the real header through it while their quote-form `#include "syscall.h"` still resolves next to the including `.c`, so no `-I` into `src/` is needed at all. **A `c_standard` that is a trap**: `-std=c11` sets `__STRICT_ANSI__`, which hides `syscall()` and `sigset_t`, and the public header then fails to parse at `io_pgetevents`; declaring `c_standard = "gnu11"` LOOKS like the fix but mcpp 2026.8.27.2 accepts the string and still emits `-std=c11` (visible in the emitted `compile_commands.json`), so `-D_GNU_SOURCE` in `cflags` is the spelling that takes effect. **Symbol versioning in a static package**: `io_getevents` and `io_cancel` have no ordinary definitions upstream — the functions are `io_getevents_0_4` etc. publishing short names through `.symver … @@LIBAIO_0.4` — which resolves for an executable under both ld.bfd and lld, but not when a consumer builds a `.so` straight out of these objects; that needs upstream's `src/libaio.map`, exactly as upstream's own `libaio.a` does) |
 | C++-source compat, one depending on the other | [`compat.abseil`](../pkgs/c/compat.abseil.lua) (151 TUs; a wildcard over `absl/**` trimmed by upstream's test/benchmark naming conventions) · [`compat.protobuf`](../pkgs/c/compat.protobuf.lua) (the libprotobuf runtime, 79 TUs transcribed from upstream's own `src/file_lists.cmake`; declares `compat.abseil` as a dependency because protobuf's public headers include `absl/…`, and its `gzip` feature defines `HAVE_ZLIB` and pulls `compat.zlib`, while `upb` adds protobuf's 64-TU C runtime out of the same tarball. It also exposes **`protoc`** as a `kind = "bin"` target, so a consumer writing `tools = ["protoc"]` gets the compiler built for its own machine out of the same package it links — making a generator/runtime version mismatch inexpressible) · [`compat.re2`](../pkgs/c/compat.re2.lua) (22 TUs, upstream's own `RE2_SOURCES`) · [`compat.redis-plus-plus`](../pkgs/c/compat.redis-plus-plus.lua) (redis++ 1.3.13 — the sync client, 17 TUs + `patterns/redlock.cpp`, depends on `compat.hiredis`; the one header CMake would generate, `hiredis_features.h`, is snapshotted via `generated_files`, and the async/TLS TUs are left out so the base build stays a two-package pair. An `async` feature adds the libuv-backed `AsyncRedis` interface (the 9 async TUs + `compat.libuv`; `event_loop.cpp` runs `uv_run` on a background thread, and `<hiredis/adapters/libuv.h>` arrives through compat.hiredis' wrapper headers). Two versions, one on each side of the source-structure watershed, share this ONE source list: 1.3.13 (modern 17-TU layout) and 1.3.3 (pre-`redis_uri.cpp`/`redlock` 15-TU layout) — the union works because 1.3.3's TUs are a strict subset, so exactly two globs match nothing there (a warning, not an error; same trick as compat.catch2)) | · [`compat.sqlitecpp`](../pkgs/c/compat.sqlitecpp.lua) (the RAII C++ wrapper over SQLite. Upstream vendors sqlite3 as a GIT SUBMODULE, so a source tarball simply does not contain it and the library cannot link — the dependency edge on `compat.sqlite3` replaces the submodule, and does it better: two consumers of SQLite in one link now share ONE amalgamation instead of each embedding a private copy with its own compile-time options. Its two CMake knobs are deliberately not set — `SQLITECPP_USE_ASSERT_ON_ERRORS` changes the error model from throwing to aborting, and `SQLITE_ENABLE_COLUMN_METADATA` has to agree with how SQLite ITSELF was built; both are the consumer's call, and the headers already guard them with `#ifdef`)
