How AI was used in this PR

Codex implemented the scoped Ask User rendering changes, added tests for historical answer handling, and ran the verification commands below. I reviewed the diff and adjusted the live answer cache update to avoid touching older duplicate questions.

Proposed Changes

• Makes Ask User choices read as an ordered list with visible option descriptions, so users can compare the available choices without relying on hidden title text.
• Adds a batched-question flow that shows one active question at a time, keeps answered questions as compact summaries, and lets users revisit earlier answers while the batch is still pending.
• Keeps selected Ask User answers visible after submission and when reviewing historical sessions, including multi-question batches whose answers are stored as ask_user prompts.
• Improves the batched-question handoff with selected-answer acknowledgement, reduced layout bounce, and scroll clearance so the next question and options stay comfortably above the composer.
• Preserves accessible button semantics with aria-pressed for selected choices and description text connected via aria-describedby.

Testing Instructions

• npx eslint --fix apps/ui/src/data/queries/use-agent-run.tsx apps/ui/src/ui-classic/components/session-view/conversation/index.tsx apps/ui/src/ui-classic/components/session-view/conversation/index.test.ts tools/common/ai/sessions/entry-types.ts apps/ui/src/ui-classic/components/session-view/conversation/style.module.css
  • CSS module reports the expected "File ignored because no matching configuration was supplied" warning.

• Verified the Ask User option list in both light and dark themes with a temporary Vite harness and Playwright screenshots.

Reviewed end-to-end, dark and light mode, closed and re-opened the app. Everything works as described.
Just a few non-blocking nits inline. Nice work on this! 🚀
