Problem

RecompileScriptsでリコンパイルを実行する例_リコンパイルされたクラスのメソッドを呼び出せる intermittently fails on CI with MissingMethodException: Default constructor not found for type Foo (seen on Unity 6000.3.18f1 and 6000.5.1f1).

Trigger Conditions

It runs right after ..._csc_rspで追加したスクリプティングシンボルが有効になる (added in e28f85f), whose TearDown deletes csc.rsp.
The next RecompileScripts then recompiles every assembly.

Root Cause

RecompileScripts waits only until EditorApplication.isCompiling becomes false; it does not wait for the domain reload.
The reload usually completes before the test resumes, but sometimes it is still pending (the log shows domain reloads=0 for that refresh).
The test then reflects on the old Assembly-CSharp, which still holds the static class Foo from the previous test.

Solution

• After RecompileScripts, wait on a static flag set before the yield. Static fields reset on domain reload, so the flag shows whether the reload has happened yet.
  • Not WaitForDomainReload: it throws when the reload has already completed inside RecompileScripts, which is the usual case.
  • Not InternalEditorUtility.IsScriptReloadRequested(): it is internal.
• Create the generated script and csc.rsp under Assets/APIExamples/Scripts/Runtime instead of Assets/, so that only the APIExamples assembly is recompiled. The csc_rsp test takes 4–9 s instead of 27–49 s.
• Also includes the CI Unity version upgrade (b77fdb8).

Verification

• Five CI reruns across all six Unity versions passed, but the delayed reload did not occur in any of them, so CI has not exercised the wait.
• Locally on 6000.0.43f1, the delayed reload occurred once (reload requested but not yet done right after RecompileScripts), so it is not specific to Unity 6.3 and later.
