Merged main without rebasing. Fixed the empty pre-steer fold, updated the existing scroll fixture to fold work, and tightened the imported-work assertion. vp run check:changed passed through Blacksmith, including 177 scoped tests. Real Replay (dev) provider and web client verified at desktop/narrow widths in light/dark themes. Native mobile and Electron remain unverified.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — Earlier assistant replies and progress messages now remain visible outside Worked-for folds on web and mobile. This changes the default collapsed conversation presentation and requires human confirmation of that product choice.

Web and mobile settled-turn folding now keeps assistant messages visible while folding eligible work entries. The initial web fold is added only when its first segment contains hidden non-compaction work. Tests update timeline expectations for work, imports, turns, and steer segments.

Explanation
Active direct target: #8879. Closed #8075 is historical context only. The web fold logic now skips every timeline entry with kind "message" when building hidden entries. The mobile logic applies the same rule to entries with type "message". Tool and reasoning work remains eligible for the Worked for fold. The web and mobile tests cover earlier assistant prose, tool work, steers, imported work, and turns without tool calls. The implementation meets #8879's requirement that folding cannot hide the substantive assistant response.
Explanation
The source changes are limited to the web and mobile fold predicates and the related empty-fold behavior. The test changes verify visible assistant messages, folded work, steer boundaries, imported work, and scroll behavior for this feature. The browser test removes timer control and uses layout assertions for the same fold expansion scenario. No unrelated production behavior, heuristic from closed #8075, or unrelated refactor appears in the reviewed diff.
Explanation
The description explains the problem and change, links the related issue, and gives focused test results and UI screenshots. It does not use the template’s exact section headings, but it includes the required information, including scope context and verification.

Note
Written by gpt-6.1-sol on behalf of Maria
Merged current main without rebasing. Kept the web/mobile prose-visibility change and fixed the empty Worked-for row before a steer when only later segments contain work. The existing scroll test now expands tool work rather than assistant prose, and waits for layout through its assertions instead of advancing fake timers. Tightened the imported-work assertion.
Superseded-attempt folding remains unchanged: it deliberately folds partial interrupted output, independently of Worked-for. Completed replies retain their existing exemption. Per-message copy controls would expand this change's scope, so they remain unchanged.
Verification: vp run check:changed through Blacksmith; real Replay (dev) provider and web client at desktop/narrow widths in light/dark themes. Earlier prose stays visible both collapsed and expanded; tool rows still toggle. Native mobile and Electron were not exercised.
Before:
earlier prose hidden in the baseline
After:
I tested this PR at 3d7853b437 with a simplified copy of a real Claude run (claude-opus-5-5). The run wrote a full summary, made two memory file writes, then ended with a one-sentence note.
On 0.1.7-nightly.20261103.4138, the fold hides the summary and only the note stays visible. With this PR, the summary stays visible. I tested this at the logic level with deriveMessagesTimelineRows, not in the running app.
Evidence that this PR also fixes a case #8879 and #17382 don't name: the explanation written before AskUserQuestion.
Setup: desktop 0.1.6, macOS arm64, Claude Code provider, claude-opus-5-5. In each test turn the assistant wrote an explanation and then called AskUserQuestion. While the question was pending, the explanation was visible. After the answer, when the turn ended, it folded under "Worked for Ns". The answered-question row stayed visible, because it is exempt at MessagesTimeline.logic.ts:1144. So the thread shows the question and the answer without the context the user answered from. I tested three variants:
echo, then text, then questionhtml_render page, then text, then question (the page stayed visible and the text folded)On main 3ee5515 nothing exempts the message before a user_input_request. This PR keeps every message entry out of the fold, which covers it. One caveat: when Claude 5.x writes the explanation as a single thinking block (#27238), it is a reasoning entry and still folds. #27271 handles that half. Screenshots below.
Drafted with Claude Opus 5.5 (claude-opus-5-5) in Claude Code, via t3 triage.
