Summary

Base red on feat-cmux-next (fleet full cmux-tui test run on Linux, base b657cec job dd03fbf83bb438cb229fcabd, tip 78ee0e1 job 3dc68e186d0f4b66de9f6179):

• acpmux::hub_integration fork_through::background_task::a_claude_background_shell_reports_how_it_ended
• acpmux::hub_integration fork_through::background_task::a_shell_moved_to_the_background_reports_how_it_ended
• acpmux::hub_integration fork_through::processes::process_list_shows_how_each_shell_ended

All three fail with one extra field: "description": "Run npm run dev" (and "Run cargo test", "Build"). #34845 intends this: a background shell's background_task_update and its process row now carry the Bash call's description (docs/background-processes.md), so a client that never loaded the call still names it. The tests were not updated. They now expect the stand-in's descriptions. Test-only change.

Testing

Focused command: cmux-ci run --class light --script scripts/ci/cmux-tui-rust-check.sh --os linux --arg test --ref SHA.

• Base (tip, job 3dc68e186d0f4b66de9f6179): the three tests fail.
• Head 64b075b (job 2d38678b15bcd3b5d083b4e3): the three pass; the rest of the red list is the other base reds of this batch.
• macOS head, filter fork_through::background_task (job 9e6e02995944d0971595ae6c): 6 of 6 pass.
• Linux all mode at the head (job 0fb467b16ab97a4d78bdb370): clippy pass; fmt red only on acpmux/src/claude_stdio/inbound.rs:287, which is red the same way at the tip (job 74f9ed3184f1aaecf528b4c3) and not in this diff.
• python3 scripts/cmux-next/prepush-gate.py: no new violations.

Observed / Not run

• Observed: the results above.
• Not run: the processes test alone on macOS (the background_task filter ran there).

Summary by cubic

Updates the hub_integration background task and process tests to expect the new description field that #34845 added to background task updates and process rows.

• Test-only change; the assertions now include the Bash call's description so a client that never loaded the call still names it.

^{Written for commit 64b075b. Summary will update on new commits.}

Review (independent review subagent, Claude): SHIP at 64b075b

Read the diff, the culprit change and the covered code at origin/feat-cmux-next: the fix is at the root cause per the culprit's stated intent and keeps the test's purpose (no skip, retry, longer wait or loosened assert). No build or test was run by the reviewer; the fleet results are in the description.
