W install image — edge
Pre-release
The W install image, rebuilt every night from the tip of main and again
after every release. This is the only image W publishes — there is no separate
per-version download.

W is a rolling distribution, so the release number and the build date say two
different things: 0.23.0 is which version of W's own configuration this is,
and 2026.10.15 is the day its packages were pulled from Arch. Both are recorded
in /etc/os-release on the installed system as IMAGE_VERSION and
W_BUILD_DATE. An image of the same release built a month apart is a different
set of packages — that is normal, and it is why this download is rebuilt nightly
instead of being frozen per version.

The checksum only catches a broken download — it sits on the same page as the
file. The image's signature is its build provenance: a Sigstore attestation that
this file was built by this repository's edge-iso workflow from the commit
above, which is a release snapshot signed with the W release key:
gh attestation verify w-0.23.0-2026.10.15-x86_64.iso --repo tarkh/w
# in a clone of the repository — the key is the one every W machine trusts
