Summary

Plans three m0 fix quests suggested by moq-dev/studio#73 and moq-dev/studio#74. All three join m0 under the rule that fixes join m0:

• A browser helper exits with the studio [S]: no orphaned CEF helper after a crash, kill, or timed-out test, on every desktop.
• Nightly and the browser suite pass [M]: nightly has failed since 2026-11-04. This quest covers render-sw's SIGTRAP, cookies_survive_a_restart, and the X11 clipboard test.
• GPU tests exit cleanly on NVIDIA [S]: 7 compositor GPU tests crash on exit on nixos.

No public API or wire impact; quest files only.

Decisions

• Browser helper follow-up: ✅ Yes, m0; Yes, m1; Drop it
• Nightly follow-up: ✅ Yes, m0; Yes, m1; Drop it
• NVIDIA exit-crash follow-up: ✅ Yes, m0; Yes, m1; Drop it

Automated review by review (OpenAI)

Reviewed 7d365b7 against 306e114. No actionable findings.

The three follow-up plans capture the outstanding issues from #73/#74 without treating the X11 or loader fixes as solving them. Direction is sound: reproduce and fix teardown/test failures at their causes, include helper descendants and every desktop, and recheck current nightly failures before implementation. The linked nightly run is confirmed failed.

Verification: GitHub-only review of all four changed planning files and the source PR context. No implementation changes, quest context, tests, hardware reproduction, or independent validation of the entire nightly failure history. These plans are not evidence that the failures are fixed.
