Remove test combinations nobody acts on
A test grid that grew for years, cut back to the combinations somebody would actually act on.
The ticket
Reduce a pipeline matrix to the combinations that are actually acted on.
Acceptance criteria
- Each removed combination is justified in writing
- The remaining set still covers the supported platforms
- Minutes saved are recorded
- The supported-platform list is confirmed with whoever owns it
What lands as proof
A written coverage argument for what remains, so the reduction is a decision rather than an omission.
Why teams defer it
- Removing a combination is only safe if you know what it covered, and nobody tracks that.
- The matrix grew by addition, and nobody has ever been asked to justify an entry.
Questions
- What does the agent actually change?
- The ticket is scoped to one outcome: reduce a pipeline matrix to the combinations that are actually acted on. Work that serves that outcome is in scope, and anything outside it is left for a separate ticket, so the pull request stays reviewable.
- How do I know the work is done?
- The pull request carries the evidence, not only the diff. Here that means the coverage argument written down alongside the removal, so a reviewer can confirm the result without reproducing the work locally.
- How much oversight does this need?
- The run stops for the plan, and the review bar is raised afterwards so that smaller suggestions block the merge too, not only serious findings.
