Summary

Keep development tests outside the UPM source and unitypackage export, and expand the EditMode suite to cover published managed-reference behavior. Run the Tests workflow on pull requests and pushes to main, so an update to a pull request branch starts a single EditMode matrix.

Scope

• Move the existing test assembly, fixtures, helpers, and metadata to Assets/Tests/SerializeReferenceExtensions, preserving asset GUIDs and assembly identity. Document the development test location and distribution boundary in AGENTS.md.
• Include the coverage work merged from Cover published managed-reference behavior with specification tests #114: managed-reference selection, Inspector labels, subtype drawers, reset operations, and type-candidate contracts. Run graphics-dependent Inspector tests under Xvfb with software OpenGL on Linux.
• Restrict the Tests workflow's push trigger to main. Retain pull request and manual triggers, the Assets/** change filter, the Linux Unity 2021.3.45f2 / 2023.2.22f1 matrix, and the final Verification gate.

Two value-type variance reproductions from #114 remain Explicit because they expose an existing product defect on Unity 2023.2. They preserve the exclusion assertion and are skipped by the continuous suite pending a separate product fix.

Verification

• At relocation commit ea3045f, all 22 moved files were byte-identical to the base, including metadata; existing GUIDs and assembly references were preserved. The later test additions and changes are described in Cover published managed-reference behavior with specification tests #114.
• Exported a local unitypackage through the existing UnityPackageExporter.Export method and inspected all 23 asset paths and archive contents: no tests, fixtures, helper scripts, or test assembly. After integrating main, checked that all tests remain outside both distribution roots and that production code and the exporter match main.
• Parsed the workflow YAML and confirmed the main push restriction and retained pull request / manual triggers. Independent review found no actionable defects in the relocation or trigger change; the specification-test review and limitations are recorded in Cover published managed-reference behavior with specification tests #114.
• Trigger-change commit 88cd071 produced exactly one Tests workflow run (pull_request) and passed both Linux EditMode versions and Verification.
• Integrated current main (f8c8ed6, including Fix Inspector updates after SubclassSelector type changes #113) and moved its newly added Inspector change-check test and metadata outside the package without changing their contents or GUID. All 24 pre-existing main test files now reside in the development test tree. Production code and the exporter match current main.
• Latest-head Linux CI after integrating main: Unity 2021.3.45f2 76 passed; Unity 2023.2.22f1 82 passed, 2 explicit known-defect reproductions skipped; 0 failures. Both XML artifacts were checked, including all three relocated ChangeCheck cases passing on both versions. Final Verification succeeded.
• Independent review of the integrated main changes and test relocation found no additional actionable defects.
