Checksum dont seem to generate on latest version for Ubi tool

[Sytten]

Hello!
It looks like the checksums are not being written to the lockfile anymore on MacOS on the latest version for ubi provider.

Given

[settings]
lockfile = true
experimental = true

[tools]
yq = '4.44.3'

It will generate:

[tools.yq]
version = "4.44.3"
backend = "ubi:mikefarah/yq"

where it used to generate:

[tools.yq]
version = "4.44.3"
backend = "ubi:mikefarah/yq"

[tools.yq.checksums]
yq-macos-aarch64 = "sha256:559a594ef7a6ebc5b81a67b7717fb3accedd266d8fa7d8352da7fec9e463f48b"

Happy to help debug, the code seem to have changed a lot in that section so maybe a bug?

Checksums are written for ubi: tools — the shape changed, and there is a second thing that may be what you actually hit.

Measured on v2026.8.2, with mise.lock present:

[[tools."ubi:mikefarah/yq"]]
version = "4.44.3"
backend = "ubi:mikefarah/yq"

[tools."ubi:mikefarah/yq"."platforms.windows-x64-yq.exe"]
checksum = "blake3:273dfc695cde969181db0ad9af105c9264fb2ee6629859ec7c3d134107378bb2"

Two differences from the [tools.yq.checksums] block in your post: checksums now live under a per-platform table rather than a checksums map, and the default algorithm is blake3 rather than sha256.

The part that surprised me: mise does not create mise.lock on its own. With lockfile = true and no lockfile present, mise install reported checksum generate windows-x64-yq.exe and wrote no file at all — I confirmed it twice, via the setting and via MISE_LOCKFILE=1. Creating an empty mise.lock first and re-running produced the block above immediately. So if the file was ever removed, or was never created by mise lock, everything looks like "checksums stopped being generated".

Worth checking on your side whether the lockfile existed at the time; if it did and checksums were still absent on that version, that is a different bug from what I can reproduce today.
