nav-pilot: release versions are not comparable semver, so mise picks an older release as latest #818
Closed as not planned
Description
2026.09.12-225921-bb3fbb6 is not valid semver: 09 has a leading zero and there are two hyphens, so the whole tail parses as a prerelease. Tools that sort by semver get the order wrong.
Measured with mise 2026.9.1:
$ mise latest 'github:navikt/copilot[exe=nav-pilot,version_prefix=nav-pilot/]'
2026.09.11-094828-baf3c85 # newest release is 2026.09.12-225921-bb3fbb6
Pinning the version works, so the mise install path is usable, but unpinned users silently get a stale binary. dpkg compares digit runs numerically and sorts our versions correctly, so apt is unaffected. Homebrew is unaffected because the tap pins each version explicitly.
A scheme change would touch the tap, install.sh, the release notes and cplt, which uses the same scheme, so it is a decision, not a fix. One option that stays date-based and sorts correctly:
2026.9.12-225921+bb3fbb6
No leading zeros, one hyphen, sha as build metadata.

docs(install): pin the mise version
Starefossen commentedon Sep 14, 2026
Deferred, deliberately.
The blast radius is smaller than it first looked: this is mise/ubi only.
dpkgsorts our versions correctly, verified against the packages now in the apt pool, and brew and the install script both resolve the right release. So the users affected are those installing through mise, and the fix costs a version-scheme change that breaks every existing tag prefix and every pinned install, plus a transition for the apt pool and both taps.Not worth that today. Revisit if mise becomes a common install route.

Closing as won't fix (owner decision 2026-10-31). Changing the version scheme would break tag prefixes, the tap, install.sh, cplt and pinned installs, for one install path.
Workaround for mise users: pin the version instead of relying on latest, e.g.
mise use 'github:navikt/copilot[exe=nav-pilot,version_prefix=nav-pilot/]@2026.10.30-103503-58ab4f5', and update withnav-pilot upgrade. Homebrew, apt and install.sh are unaffected.
