Greptile Summary

This PR is a pure revert of #61225, which was a codex-generated PR that added test cases to reproduce session stall and restart drain bugs. No production code is changed — only three test files are affected.

• All three files (agent-runner-execution.test.ts, agent-runner.misc.runreplyagent.test.ts, get-reply-run.media-only.test.ts) are test-only; the revert removes test coverage that was introduced by [codex] Reproduce session stall and restart drain bugs #61225.
• The remaining tests in each file are well-structured, with proper mock isolation, appropriate beforeEach/afterEach cleanup (vi.useRealTimers(), resetSystemEventsForTest(), clearMemoryPluginState()), and consistent use of vi.hoisted().
• The PR description does not explain the motivation for the revert (e.g., flaky behavior, incorrect assertions, or conflicts with in-flight work). A brief rationale would help reviewers and future maintainers understand whether the removed tests should be re-landed once the underlying issues are addressed.

Confidence Score: 4/5

Safe to merge — only test files are reverted, no production code is affected.

Score is 4 rather than 5 because reverting tests explicitly written to reproduce identified bugs (session stall, restart drain) removes regression coverage without any stated justification. The remaining test suite is solid and no functional code changes are involved, but the missing rationale leaves open whether the removed tests had correctness problems or were reverted for other reasons.

No files require special attention. All changed files are test-only. The motivation for the revert is the only open question.
