Each steer now starts its own "Worked for" fold, so work done after a steer sits under it instead of inside the fold above it. Durations run from steer to steer and still add up to the run. Each fold expands on its own. Fixes pingdotgg#15279

🟡 Medium lib/threadActivity.ts:1088
Consecutive steers assign the interval after an empty section to the preceding fold, so the duration shown under an earlier prompt includes time belonging to the later prompt. The .filter removes empty sections before nextSection is selected; retain those steer boundaries and skip only sections without foldable work when creating folds.

Fixed in 71d65b0. A section with no folded work now passes its time to the next fold, not the previous one. Each fold ends at the steer right after it. Same change on web. Covered by "gives the time after a steer without folded work to the next fold".

When a steered run changes from running to interrupted, the completion effect adds only the bare runId, so the final fold keyed as ${runId}:${anchorId} stays collapsed and the You stopped after ... work remains hidden. Expand all fold keys for the interrupted run (or make the fold lookup treat the bare runId as a prefix match) instead of relying on the bare key matching only the pre-steer section.

Fixed in 71d65b0. A bare run id now expands every fold of that run, so the interrupt effect (and web's citation and interrupt paths) open all sections again. A single-fold run still uses the run id as its key. Collapsing a fold that's open because of the run id clears that id too, so the fold can always be closed.

A steer boundary is assigned to the first later entry with any runId, so a persistent subagent/resource event from another run consumes pendingSteer and segments that unrelated run instead of the steered run. The steered run's subsequent work therefore remains in its pre-steer fold. Track the steer message's run and apply pendingSteer only when the later entry's run matches it.

Fixed in 71d65b0. The steer boundary now records the steer's run and applies only to that run's entries. Each section also anchors on its own first entry, so it can't share an anchor with another run's fold. Covered by "splits only the steered run when another run's work follows the steer".

When only the pre-steer fold is expanded, attachCreatedThreadSummaries still removes its inline thread_created event if the post-steer fold for the same run remains collapsed, so the created-thread card disappears from its timeline position and appears only after the final answer. Track collapsed state by fold/entry section rather than solely by runId.

Fixed in 71d65b0. attachCreatedThreadSummaries now follows the state of the closest fold above each created-thread row, falling back to the run's first fold. It no longer treats the run as collapsed when any one of its folds is.

Queued prompts incorrectly split the preceding run's fold, so activity emitted after the queued prompt is rendered as a separate work fold below that unrelated prompt. pendingSteer is assigned for every user message; restrict this boundary to messages whose inputIntent is steer or promoted_queued_to_steer.

- Only steers split a fold, and only in the steer's own run. - Time after a steer with no folded work joins the next fold. - Each fold anchors on its own first entry. - An interrupt or citation still expands every fold of the run. - A created-thread card follows the fold above it.
Problem
When you steer a running turn, the settled thread shows one "Worked for …" fold under the first prompt, then the steer, then the answer. That fold hides the work done after the steer too, so it reads as if the agent did all the work before the steer and then answered it instantly.
Fixes #15279.
Fix
A steer now splits the settled fold, the same way an automatic wake already does: prompt → "Worked for 6m 11s" → steer → "Worked for 49m 8s" → answer.
deriveTurnFolds(web) andderiveThreadFeedRunFolds(mobile) still group work by run. They also record where each steer falls in that same run and emit one fold per section that hides work. Queued prompts and other runs' entries don't split a fold.${runId}:${anchorEntryId}. A run with one fold keeps the run id as its key and row id. A bare run id (from an interrupt or a citation) still expands every fold of the run.Scope and approval
One problem: steered turns fold their work in the wrong place. #15279 was triaged by @juliusmarminge, who confirmed the cause and suggested this direction ("split only the settled fold into sections at each steer"). Mobile has the same per-run grouping, so it gets the same change.
Verification
main(c5bc98db03) with real data: I copied a read-only snapshot of my own database into the worktree's.t3and opened a Claude thread with a steer in an isolated Playwright browser. It showed one "Worked for 55m 19s" fold above the steer. With the fix, it shows "Worked for 6m 11s" above the steer and "Worked for 49m 8s" below it (6m 11s + 49m 8s = 55m 19s). Expanding the second fold shows only the post-steer work, and the row stays in place.vp test run apps/web/src/components/chat/MessagesTimeline.logic.test.ts apps/mobile/src/lib/threadActivity.test.ts: 225 passed. The new web and mobile tests fail without the fix. The old "keeps the duration header at the initiating prompt" test now expects the settled fold below the steer. Its live-header assertions are unchanged.tsc --noEmitpass. Scoped lint has 0 errors (all warnings already exist onmain). Format passes.Before:
