+- LLVM ships as a binary seed. C is accepted because the compiler is LLVM, in
+  programs too, important ones included.
+- cargo's C dependencies are accepted.
+- Perl and Python come to ToyOS.
+- Make it work, then optimise, then compare: no performance study now, and no

+
+**To build** (2026-10-01), in an order that is open. Where a stage names
+libc's state it is `userland/libc` at `15625e0cb`.
+- **The `libc` crate gains a ToyOS module**, checked by `ctest` against
+  `userland/libc`'s headers. `libc` 0.2.189 has none (`rg -i toyos` over its
+  `src` matches nothing) and is empty for an OS it does not know
+  (`src/lib.rs`), and `ToyOSOrg/libc` does not exist (GitHub's API answers
+  404). cargo's `curl-sys`, `libssh2-sys` and `libgit2-sys` import its C types
+  unconditionally.
+- **libc gains `select`.** curl 8.21.0, which `curl-sys` 0.4.90 builds, does
+  not compile without it (`lib/curlx/wait.c`: `#error "We cannot compile
+  without select() support."`) and waits on its sockets through it: `select.c`
+  calls `poll` only under `HAVE_POLL`, which `curl-sys` does not define. Stage
+  3 of `issues/kernel/a-childs-end-is-an-event-and-a-parent-takes-its-children-down.md`
+  builds none, because a descriptor is a handle and passes `FD_SETSIZE`; what
+  `select` answers for such a descriptor is open.
+- **libc gains what cargo's libraries call**, among them `setvbuf` and
+  `socketpair`, which it does not define; a `realpath` that resolves, a file
+  `mmap` and record locks
+  (`issues/build/libc-refuses-what-toyos-cannot-yet-answer.md`); file
+  identities
+  (`issues/build/libc-stat-answers-one-serial-number-for-every-file.md`),
+  served like the locks by fsd; and socket descriptors that are pollable and
+  can be non-blocking
+  (`issues/build/libc-close-of-a-socket-ends-the-process.md`). Read from each
+  library's source and not run: SQLite's default VFS takes `fcntl` record
+  locks and keys them on `st_dev` and `st_ino`; libgit2 opens every repository
+  through `realpath` and reads packs through a file `mmap`; curl and libssh2
+  wait on non-blocking sockets, curl's multi handle wakes through a
+  `socketpair`, and its TLS key log sets its buffering through `setvbuf`.
+- **cargo's eight C libraries are cross-built for ToyOS**: curl, libgit2,
+  libssh2, OpenSSL, SQLite, nghttp2, zlib and blake3. Compiled and linked
+  with the toolchain's clang against that libc's C sysroot, the sources of
+  nghttp2, zlib and blake3 build with nothing undefined, and the other five
+  stop on headers, types or functions libc lacks. `openssl-src` 300.6.1 knows
+  no ToyOS target and refuses one it does not know (`src/lib.rs`), and
+  `openssl-sys` is a `cfg(unix)` dependency of `curl-sys` and `libssh2-sys`,
+  which ToyOS is not. Open until M4: whether cargo's OpenSSL is built for
+  ToyOS through its Perl `Configure`, or cargo takes curl's rustls backend
+  there.
+- **The tools a self-build runs are built for ToyOS**: Perl and Python, ported
+  to start a child by spawn and never by fork; brush as the POSIX `sh`
+  (`issues/build/ninja-runs-every-command-through-a-bin-sh-toyos-does-not-have.md`);
+  uutils; make; CMake, its libuv ported to spawn; and awk. Those written in C
+  or C++ wait on stage 3 of the child-process track and on
+  `issues/filesystem/there-is-no-dev-null.md`. A search of Perl 5.44.0's
+  sources for `posix_spawn` matches nothing. Open: which Python, which make and
+  which awk.
+- **`pkg` installs a toolchain**: an archive past 256 MiB, and links. It
+  inflates a whole archive in memory under `MAX_INFLATED`, 256 MiB, and refuses
+  every link (`userland/pkg/src/main.rs`, `archive.rs`). A toolchain's size is
+  measured on a proxy, the Linux-host release
+  `toolchain-linux-x86_64-48dd24f826263d6c`: stripped with `llvm-objcopy
+  --strip-all`, its `librustc_driver` is 184.7 MB, its clang 122.8 MB and its
+  lld 78.6 MB, beside 181.1 MB of `x86_64-unknown-toyos` libraries. And the
+  loader finds a package's own libraries
+  (`issues/filesystem/a-package-cannot-ship-its-own-libraries.md`): rustc's
+  launcher names `librustc_driver` as needed (`llvm-readobj --needed-libs`).
+- **The toolchain is `pkg` packages, and the image carries none of it.** Open:
+  how it is split into packages, and how a self-host test's guest reaches
+  them.
+
 **Blocked on other tracks.** M2 needs packages over HTTPS
 (`issues/filesystem/a-package-is-a-directory-under-apps-and-the-installer-is-a-program.md`)
 and the network stack under it (`issues/hardware/the-lan-is-not-yet-production-grade.md`,

+# Kernel issues cite the cut HTTPS tests as cover that runs

+three issues still give one or both as tests that run:

+
+One citation is cover no tier holds and no track owes. The last two give
+`https_tls13_e1000e` as what reads `Refusal::BarReferenceEmpty`: its judge
+asserted how many BARs the boot kept back, and that refusal's words. Outside
+`kernel/` and `issues/` no file names the refusal, its words or the kept-BAR
+record, and stage H of
+`issues/build/the-guest-suite-runs-only-what-no-cheaper-tier-reaches.md` lists
+that test for its fetch alone, on a line stage 3 of
+`issues/design-debt/the-internet-clients-work-unchanged.md` deletes.
+
+**Exit**: none of the three cites a test of either name that the tree lacks,
+and `BarReferenceEmpty` has a reader that reds when the refusal goes, or one of
+the three lists it as unread.
