- vibetyper/msty-studio: unversioned AppImage URLs → HEAD/Last-Modified check via custom update.sh, refreshes sha256 when upstream binary changes - zellij-ps: switch to branch-tracking (master tip via Gitea API) since helper-scripts repo has no tags - all three expose passthru.updateScript so the existing CI workflow discovers them via is_custom_update_script

# Upstream publishes to an unversioned URL (MstyStudio_x86_64.AppImage) — no
|
|
# version-pinned URL and no usable GitHub release. To still catch updates, we:
|
|
# 1. HEAD the URL and read the Last-Modified header
|
|
# 2. Compare to the value stored as a `# last-modified:` comment in default.nix
|
|
# 3. If changed: re-download, compute sha256, update hash + comment, commit
|
|
#
|
|
# The version attribute stays static (manual bump) — only the binary hash is
|
|
# refreshed automatically.
