Summary

• Prevent the 15-minute process limit from interrupting healthy EditMode GUI tests on slower hosted runners. The verified Unity 2021.3 suite needs 15 minutes 51 seconds.
• Give the complete Editor process 20 minutes and record timestamped test starts and finishes, including runs that cannot write their final result XML.

Scope

• tests.yaml: process budget 900 → 1200 seconds; timestamped Editor logging.
• Batch-only progress callback through Unity Test Framework's ITestRunCallback API in the existing Editor test assembly.
• Package code, test assertions, individual condition deadlines, and required Editor versions are unchanged.

Verification

• CI run 39368953612, head 2a8e139caa51d9381d63c6e3fee7467edcc3bc65: all required checks passed.
• Unity 2021.3.45f2: 198/198 passed, 0 skipped; suite duration 951.27 seconds. Completed beyond the previous 900-second process budget.
• Unity 6000.6.6f1: 208 passed, 0 failed, 2 existing explicit skips; suite duration 631.19 seconds.
• Both Editor logs completed without a native SIGSEGV report.
• actionlint passes for tests.yaml; git diff --check passes. A scoped Unity 2021.3 smoke run also verified progress callback output.

References

• Diagnostic run 39366906704: Unity 2021.3 passed 177 tests and was still advancing immediately before the old process limit. The next layout check began with approximately 17 seconds left; that check alone needed 43 seconds in an earlier successful run. GUI test durations were approximately 1.6 times that earlier run.
