Several agent-pane integration tests still assert rendering that later changes replaced. Update them to preserve their behavioral checks against the current output-token label (#25118), virtualized thread rail (#25152), immediate removal of read steer controls (#25785), ended-agent avatars (#25205), Markdown message line breaks, and workerless code fallback. Mermaid now checks the complete refused source; the rail checks its accessible full-list size; ended avatars must stay outside the running wave.

Observed / Not run

• Base 5b181c2efb9fd315e57ae3160dd44fc08aff6dbb: the grouped remote reproduction had 50 passing and 10 failing tests, including all seven assertions repaired here (run).
• Head 7234540524875687c97953e2ed00cb2e60036967: 35 pass, 0 fail in run 40618673640. Snapshot fd7dd07d5441a5422fc2208c13ca98a1210de23a and head share tree f8ba0114255b6529f7a845f040930918842b8dbb.
• Independent Astra review: SHIP at 7234540524875687c97953e2ed00cb2e60036967.
• Focused command from webviews/: cmux-ci test --setup webviews --timeout 1800 -- bun test test/agent-pane-mermaid.test.tsx test/agent-pane-pending-steer.test.tsx test/agent-pane-turn-tokens-muted.test.tsx test/chat-minimap.test.tsx test/running-wave.test.tsx test/transcript-row-message.test.tsx.
• scripts/web-lint.sh --new-only --base 5b181c2efb9fd315e57ae3160dd44fc08aff6dbb and python3 scripts/cmux-next/prepush-gate.py passed.
• verify-local.py has unrelated localization debt, stale generated launch policy, and missing classic project/test paths on this base. Native compilation and app capture were not run for this test-only change.

Risk: low. No capture: test assertions only.

Probably yours: chat-inspector-overlay-toggle.test.ts, composer-footer-plain.test.ts fails here but not on main's latest full suite. Seen on other PRs too (likely flaky): layout.test.ts, agent-pane-queue-scroll-bottom.test.ts, agent-pane-queue-scroll-bottom.test.ts and 19 more. This PR merged before its CI finished: fix forward on main.

Not re-run automatically: web / react-apps-base-check (4), web / react-apps-base-check (3), web / react-apps-base-check (1), web / react-apps-check are not machine failures.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.
