Summary

Carry main into redesign/main (thomasluizon/orbit-tickets#746): orbit-api#799 (4b1c9d7e, thomasluizon/orbit-tickets#1572), which splits the domain-habit-freeze mutation shard into three Habit.cs character-span shards plus StreakFreeze.cs so no shard runs past the 45 minute limit.

git cherry-pick -x 4b1c9d7e applied cleanly on redesign/main 45548c59. No behaviour beyond the carried commit changes.

Test evidence

• node --test .github/scripts/mutation-matrix.test.mjs: exit 0, 25 passed.

Assumptions

None.

Manual steps

None.

✅ No new issues found.

Reviewed changes Reviewed both files in the carry from main into redesign/main, including mutation-scope coverage, workflow argument handling, and the pinned Stryker implementation.

• Balanced domain shards: Replaces the combined habit/freeze shard with three Habit.cs scopes, retaining StreakFreeze.cs in the final shard. Nested prefix exclusions preserve unique ownership of boundary-crossing mutants and cover future file growth.
• Selection and coverage tests: Updates shard expectations and adds domain-file, configuration, and span-boundary coverage. node --test .github/scripts/mutation-matrix.test.mjs passed all 25 tests locally.
• Runtime validation: The existing workflow supports the new scopes without changes. Full mutation jobs were still running when inspected, so the 45-minute runtime goal remains unverified by this review.
