The README's Linux test build has never worked: both the bridge and the
test executable carry INSTALL_RPATH "$ORIGIN" and expect libmsquic.so.2
beside them, but only scripts/build-quic-native.sh's packaged output
directory ever got that copy. A test build produced a binary that died
at once with "cannot open shared object file". Fix it where the
knowledge already lives instead of adding a README workaround: CMake
already receives MSQUIC_LIB_DIR, so the test target now copies
libmsquic.so.2 beside itself in a POST_BUILD step.
While verifying the README's own worked example end to end, found a
second, independent break in the same docker block: MSQUIC_INCLUDE_DIR
and MSQUIC_LIB_DIR were passed as paths relative to the repository
root, but CMake resolves a relative cache-variable path against the
CMakeLists.txt that consumes it, not the invocation directory, so the
compile failed on a missing msquic.h before it ever reached the
loader. Made both paths absolute with $(pwd) and documented why.

Better to have nothing than a harness that punishes refactoring
(operator ruling, 2026-09-22). Remove scripts/mutate-cultmesh.mjs
(1451 lines) and its Node dependency from the Linux QUIC dev image.
The behavioural coverage stays: native/GameCult.Mesh.Quic.Native's
scenario runner and its seams (waitseam, pollhammer, holdtimeout,
zerotimeout, closerace, and the rest) are untouched. The README and
the dev Dockerfile now document building with
-DCULTMESH_QUIC_BUILD_TESTS=ON -DCULTMESH_QUIC_DEBUG_ASSERTS=ON and
running each scenario as a direct argument to the built binary,
instead of through the harness.
docs/cultnet-selection-cut.md and docs/typescript-quic-realtime-cut.md
still name the harness; they are Self's campaign history and stay as
written.

`*.sh text eol=lf` reaches new clones only. A clone checked out before the
rule keeps scripts/build-quic-native.sh with carriage returns after pulling,
because the blob did not change: git neither rewrites the file nor reports it
modified, and the container still dies on the interpreter `bash\r`.
The README now gives the repair where a newcomer meets the container path,
and .gitattributes points to it. Verified on clones made at 367c9bc and moved
to c25de5a, from Git Bash and from Windows PowerShell 5.1: 109 CR bytes
before, none after, status clean. The line uses `;` so it runs in both.

Soul flagged (F3) two docs still describing the pre-release native QUIC
bridge: unity/org.gamecult.cultlib/README.md said Schannel, and
native/GameCult.Mesh.Quic.Native/README.md still described the older
40,448-byte committed plugin as current. The shipped bridge (since the
1.0.60/1.4.0 release, commit 0155ba8) is the OpenSSL MsQuic 2.5.9 build,
302,080 bytes, static CRT, no CRT import. Both docs now describe that build
and name what it replaced.
The OpenSSL build's NuGet package carries an Apache-2.0 notice for OpenSSL
itself (Microsoft.Native.Quic.MsQuic.OpenSSL's THIRD-PARTY-NOTICES) that the
committed Third Party Notices folder never carried - the Schannel build had
no such dependency to notice. build-quic-native.ps1 now copies it out
alongside MSQUIC-LICENSE.txt, build-unity-package.ps1 stages it into the
package output and the tracked template, and it is now committed as
OPENSSL-NOTICE.txt.

The container recipe carried a PowerShell backtick continuation in a snippet
whose next paragraph invites a POSIX shell to run it, where a backtick is not a
continuation. A continuation has to pick a shell, so the line does not have one.
The Dockerfile's own copy of the recipe still mounted one machine's checkout by
absolute path; it mounts whatever checkout is running it, like the other two.
And the requirement a newcomer meets by tripping over it: on win32-x64 the
harness needs the checkout somewhere short. MSBuild's file tracker gives out on
long paths, so a run from a deep temporary directory fails the build for every
mutant, the no-op control included. That is loud — the harness stops on a red
control and prints what the child said — but what the child says is MSBuild, not
the path.

The mount was this machine's own path, so the one documented way to build and
check the Linux bridge needed editing before it would run anywhere else. It is
the repository root now, named as the shell names it.

The image the bridge is built and mutated in existed nowhere in the repository,
and the recipe that stood in for it installed a C++ toolchain and no JavaScript
runtime — so the container could not run the harness that checks the bridge it
had just built. It is a file now, pinned to the same debian:13 digest as the
release workflow, carrying ninja, Node, setarch and MsQuic's four runtime
dependencies.
The harness configures with `-G Ninja` on linux-x64, which is what
scripts/build-quic-native.sh uses. CMake's Linux default is Makefiles, the image
carries ninja rather than make, and the default configured nothing at all: the
first run in the committed container died in cmake. It said so, because the
control now prints what the child said, which is the whole point of that change.
The seccomp requirement is stated where someone hitting it will read it — the
bridge's README, beside the recipe — rather than being knowledge the runner
assumes its caller already has.

The README claimed a rebuild reproduces the committed Unity plugin DLL. It does
not. That plugin is 40,448 bytes, predates both the static CRT and the move off
Schannel, and still imports VCRUNTIME140.dll and MSVCP140.dll; the current source
builds to 302,080 bytes with no CRT import.
What /Brepro buys is that a build reproduces itself, and the README now says
that, along with the fact that the committed plugin stays the older build until
the Unity package build replaces it.

Q9 ruled A. The Schannel MsQuic refuses QUIC_CREDENTIAL_TYPE_CERTIFICATE_PKCS12
with QUIC_STATUS_NOT_SUPPORTED, and PKCS12 is the only credential type a
provider has on both platforms, so a Windows provider could not open a
listener against the runtime this repo was shipping. The same bridge
binary passes all twenty smoke checks and the v1 gate against the OpenSSL
build, which is what Soul verified and what this now downloads.
Two digests, not one. The zip is pinned by FEE9A664 and 19,179,817 bytes;
the msquic.dll inside it by C17C6581 and 4,181,856 bytes. The earlier
report and the cut map's first record put the zip's digest on the DLL,
which is a pin that checks the archive and then ships a file nobody looked
at. Sizes ride along with both, because a digest that fails tells you less
than a digest and a length that fail together.
The CRT is linked statically. A Node or Unity host without the Visual C++
redistributable cannot load a DLL that imports vcruntime140.dll, and
Windows reports that as "the specified module could not be found" while
naming the module that was found. Confirmed on the rebuild: msquic.dll,
CRYPT32, ntdll, KERNEL32, and no CRT import at all. The DLL goes from
83,456 to 302,080 bytes, which is the price of the host not needing
anything installed.
The Unity plugin's committed msquic.dll is still the Schannel one and this
does not touch it; the next build-unity-package.ps1 run is what replaces
it, and that is not in this batch.

Soul wrote a C consumer of this ABI from the spec text, because there was
nothing to include. The struct layout, the exports and the conventions
lived in the .cpp and in prose, which is three places for one contract and
no way to notice when they part.
include/cultmesh_quic_native.h is now the contract: the 64-byte event with
every field offset asserted, the exports with their signatures, the id and
return-code conventions, the object lifetime rules, and the threading
rules. The .cpp includes it and keeps none of its own copy. The README
points at it rather than restating it.
The lifetime and return-code sections describe where the bridge is going,
not where it is; the two commits after this one make them true.

There is no Linux MsQuic binary in any NuGet package, and the v2.5.9 GitHub
release carries only test bundles, so the Windows script's approach does not
transfer. What does exist is Microsoft's Debian 13 pool, which is the same
distribution Yggdrasil runs, and the msquic source tree at the matching tag for
the POSIX headers the NuGet omits.
`scripts/build-quic-native.sh` fetches the pinned `libmsquic_2.5.9_amd64.deb`
and the three headers `msquic.h`, `msquic_posix.h` and `quic_sal_stub.h`, and
verifies all four by SHA-256 the same way `build-quic-native.ps1:14` verifies
the NuGet. A digest that stops matching is a changed dependency, not a warning.
Two details the deb forced. It carries three library files and no licence text,
so the MIT licence is copied from the one this repo already committed for the
Windows plugin — the same text for both platforms. And it ships only
`libmsquic.so.2.5.9`, with no `libmsquic.so` for `-lmsquic` to resolve against,
so the script makes that link in the extracted tree rather than in the image.
The Linux CMake branch links `-fvisibility=hidden`, so only the twelve v2
exports leave the `.so` and the Windows-only v1 five are absent by construction
rather than by discipline, and sets `RPATH $ORIGIN` so the `libmsquic.so.2`
shipped beside the bridge resolves without being installed system-wide.
`build-quic-native.ps1`'s default output directory becomes
`artifacts/quic-native/win32-x64` so the two platforms' outputs sit beside each
other instead of on top of each other. Both existing callers —
`build-unity-package.ps1:80-82` and the Native.Tests csproj `:20-22` — pass an
explicit `-OutputDirectory`, so neither is affected.
Built and smoked in the workstation's Docker `debian:13` engine pinned by
digest: g++ 14.2.0, glibc 2.41, `libgamecult_mesh_quic_native.so` 85,456 bytes
with `NEEDED libmsquic.so.2` and `RUNPATH $ORIGIN`, and the same 15-check v2 FFI
smoke that runs on Windows passes under Node 24 on that image. That is a Linux
build on a Linux host and nothing more: Q6 ruled the release artifact comes from
the Actions job, and this one is the development loop.
A Linux host still needs MsQuic's own runtime dependencies present — libssl3t64,
libnuma1, libxdp1, libnl-route-3-200 — which is now written down, because the
first smoke run failed on a missing libxdp.so.1 and the reason was not obvious
from the error.
