id: LK-20260629-ui-diagnostics-and-release-v3-0-0
date: 2026-06-29
sequence: 17
type: feat
compatibility: compatible
component: `labkit_launcher` | `1.1.2 -> 1.1.3`
component: `labkit.ui` | `3.1.3 -> 3.2.0`
scope: UI diagnostics and release v3.0.0

Context

The diagnostic work completed during the 3.x UI cycle needed a stable release checkpoint, clearer validation documentation, and CI behavior that would not run duplicate workflows for the same change.

Decision and rationale

Publish the UI diagnostic improvements as v3.0.0, document how they are validated, and avoid redundant CI triggers. Keep the release compatible with the app data produced by the preceding 2.x workbench releases.

Changes

• Release tag v3.0.0
• labkit.ui 3.1.3 -> 3.2.0
• labkit_launcher 1.1.2 -> 1.1.3

• Improved UI diagnostics and validation documentation.
• Published the v3.0.0 release line around UI diagnostics, validation docs, and duplicate CI avoidance.

User and data impact

Users gained a named release to install or restore, while failure reports contained better callback context. Project and scientific result formats did not change in this release record.

Compatibility and migration

The v3.0.0 release retained the preceding app data formats. Users could update or roll back the workbench without converting saved scientific results.

Validation

Commit 21eff4dc carried the diagnostic and validation changes; tag commit 349a7549 published v3.0.0. Exact historical local commands were not recorded.

Evidence

• Main commits 21eff4dc and release tag commit 349a7549.

Known limitations and follow-up

This record marks the release boundary; individual diagnostic mechanics are described in their earlier component history records.
