fix(ci): restore #15712's non-iOS test-harness hunks dropped by #16709 - #16745
Conversation
The squash revert of #15712 (#16709, for iOS toolbar regressions) also reverted its CI/test-harness hunks: the TEST_RUNNER_-aware SwiftTestingAssertions.sourceURL, the console-session allowlist entry for CMUX_CI_RUNTIME_SOURCE_ROOT, and the CLI test fixture isolation. #16352's guard in tests/test_app_host_test_rerun.py asserts those, so CanonicalRootTests fails on main. No iOS file is touched. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Subagent review at 4a72af6: APPROVE. The diff is the exact reverse of #16709 for the 7 non-iOS files. No iOS files are touched. Every Swift symbol it uses exists in the tree, and the review saw nothing Swift 6.0 would reject. tests/test_app_host_test_rerun.py passes 52/52. Not a blocker: forgetPersistedWindowGeometryForTestProcess, ciRuntimeSourceRootEnvironment and repositoryRoot(file:) have no callers, which matches main before the revert. They can be cleaned up later. |

Wait for the close state instead of a fixed interval.
Each drainMainQueueForCloseTest call runs until its deadline, even if the close finishes sooner. The two calls do not confirm that the close completed before the assertions. Under load, the test can assert while close work is still pending. Use the existing waitForMainQueueWork helper to wait for the prompt and panel-removal conditions.
As per coding guidelines, “A correctness test waits ON a real completion signal ... and asserts a logical invariant. It never waits a fixed duration.”
Proposed change
- drainMainQueueForCloseTest(timeout: mainActorTestMainQueueSpin)
- drainMainQueueForCloseTest(timeout: mainActorTestMainQueueSpin)
+ waitForMainQueueWork(timeout: 4) {
+ promptCount == 1 && fixture.workspace.panelIdFromSurfaceId(tabId) == nil

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Remove the unused test-only helper from AppDelegate.
forgetPersistedWindowGeometryForTestProcess is a new test-only DEBUG seam in production Sources/. It has no caller in the repository, so delete it instead of moving an unused entry point to another debug file. SessionSnapshotPersistenceWriter owns the geometry key declaration and legacy-key cleanup; no new persistence helper is needed.

It shows up on #6312, #8311 and #7787.Cause: #16709 squash-reverted #15712 to fix iOS toolbar regressions. The revert also removed #15712's CI and test-harness hunks. #16352's guard asserts those hunks are present, so the test fails.
