# This file does not build Proton. It packages a Proton tree that was already
# built, and it cannot build it: proton-ge's build runs its own steps in the
# Steam Runtime SDK image through a container engine, so it runs on the host,
# and running it inside this build would mean nested containers.
# `scripts/proton-build.sh` does the build, and this file wraps the result.
#
# Separate from the guest Containerfile because it is a separate cadence:
# hours to build, and only when PROTON_TAG moves. The guest image pulls the
# result from a registry instead of rebuilding it, which is why this file is
# not part of that build and is not reached by `make build`.

# The final stage is FROM scratch, so the image *is* the Proton tree — nothing
# to run, only something to COPY --from.

# Build and publish with `make proton-image` / `make proton-push`. **Its
# context is this directory**, not the repository root the guest build uses:
# all it needs is the two scripts beside it, and a context of the whole tree
# would hand it a multi-gigabyte `output/` for no reason.
#
# `PROTON_TAG` is the one thing to change, and the Makefile derives the
# published image's version from it. They are the same number in two
# spellings, and an image whose name does not say which Proton is inside it
# is worse than no image.

# widl generates vkd3d's public headers. Without it autoconf sets HAVE_WIDL to
# false, the headers are silently not generated, and the build dies an hour
# later on a missing vkd3d_d3dx9shader.h. Arch ships widl only inside `wine`,
# which requires multilib; the AUR's mingw-w64-tools builds it standalone, so do

# The digest is not a formality. What is extracted here has its `configure` and
# its makefiles run as root in this builder, and what they produce is copied
# into the image a box runs -- so whoever can change these bytes can change what
# runs on every host. SourceForge hands the request to whichever mirror it
# likes, over a connection this builder does not pin, and the project publishes
# no signature. The digest is the only thing that makes the mirror not matter.

# Taken 2026-09-14 from two different mirrors of v14.0.0, which agreed. A
# mismatch here is not a thing to paper over by taking the new digest: it means
# the bytes behind this exact version string changed, and that wants looking at
# before it wants fixing.
