Problem

The Timeline pane's tok/s column reads as a static number during a generation.

The value changes only when the pane refetches the timeline. tokPerSec counts completed turns plus the live estimate of the open one, and a redraw changes neither. With no new stream event, handleTimelineTick waited timelineIdleRefresh, which is 10 s. So the value held still for ten seconds and then jumped.

Measured on session 7bc33bf7-9f1a-44e8-8388-e714a4578394: subagent ad944056f60634bbb held near 150 tok/s, and the recomputed rate moved between 131 and 175 tok/s across its turns.

Fix

A session with a response in flight now refetches every timelineRefresh (1 s), so the live token estimate and the tok/s read off it follow the stream. A session with no open turn keeps the 10 s interval, so an idle live session costs no more than before.

The value is still a 60 s rolling average. It moves by a few tok/s per second, and it does not jump around.

Walkthrough

The timeline now uses a shorter refresh interval when a session has an open, non-lost turn. Otherwise, it uses the idle refresh interval. A test covers the open-turn refresh case.

Changes: Timeline refresh

Layer / File(s)	Summary
Select and apply the refresh interval cmd/agentop/tui/timeline_pane.go, cmd/agentop/tui/timeline_pane_test.go	idleRefresh selects timelineRefresh when a turn has no end time and is not marked lost. Tick handling uses the selected interval. A test verifies that an open turn triggers a refetch after one timelineRefresh interval.

Merge Risk: Low · previous review 9c679

The tok/s display may update about every two seconds rather than every second during generation. This is a minor cosmetic shortfall against the stated goal. It is low risk to merge, and the cadence can be tightened in a follow-up.

Explanation

The title names the main behavior change: a live timeline refetches every second while a response is in flight. The raw summary confirms this: an open main-agent turn selects the one-second timelineRefresh interval instead of the ten-second idle interval. The title is specific and matches the changeset, so it passes.

- Line 255: Update the refresh eligibility logic around `t.fetchedAt`,
`t.idleRefresh()`, and `m.timelineLive()` so open turns can trigger a fetch on
each eligible tick without waiting for the elapsed-time check. Preserve the
existing loading and backoff guards, and keep the elapsed-time check for idle
sessions. Add a test where a reply arrives between ticks to verify the next
eligible tick refreshes the open turn.

Summary

The fix works for the case it targets. A live session with an open, non-lost turn now refetches on every 1 s tick instead of every 10 s. FillLive recomputes LiveTokens on each request from the proxy's live byte counter, outside the cache, so each refetch carries a fresh estimate. The layout cache key includes the tl pointer, so tokPerSec is recomputed on each reply. The !tu.Lost exclusion matches FillLive, which also skips lost turns. Lost turns always have End set (agents.go sets End and Lost together), so that clause is defensive but harmless.

I checked the new test both ways. On main's timeline_pane.go, TestTimelineRefresh fails at the in-flight case ("was not refetched on the tick after a fetch"). On the PR head, it passes. go vet, gofmt -l and go test -short ./tui/ in cmd/agentop are clean. I have one non-blocking suggestion, inline.

suggestion (non-blocking): This tick chain also runs while the Events or Detail pane is open on the same session (timelineChainLive), so those panes also refetch once a second while a turn is open. In those panes nobody reads tok/s. Each reply runs handleTimelineLoaded, and that calls rebuildEventsTable() when m.pane == paneEvents. BenchmarkRebuildEventsTable/plain measures about 43 ms per rebuild here for a 2,000-event session. Before this change, that happened every 10 s plus once per stream event. Now it happens every second for as long as a response streams. Consider gating the openTurn() clause on m.pane == paneTimeline, so the Events and Detail panes keep the 10 s interval.

Review: fix: Refetch a live timeline every second while a response is in flight

Verified on head 5f845be in a clean worktree: gofmt -l tui/ clean, go vet ./tui/ clean, go test ./tui/ passes, including both new cases in TestTimelineRefresh (in-flight refetch on the tick after a fetch, and the lost-turn exclusion).

The logic is sound: openTurn() is only reached behind m.timelineLive(), which nil-checks tl (satisfying the doc comment's precondition), the error-backoff and unsupported guards still hold back the new trigger, and excluding lost turns is the right call — a lost stream's estimate can't grow. One nit below on the PR description; no code findings.

nit The PR description's Files section attributes this to timelineState.idleRefresh, but no such method exists on head — the shipped change is openTurn() plus this line in handleTimelineTick. The comment here and the code are consistent with each other; only the PR body has drifted. Suggested fix: update the body's Files bullet to name timelineState.openTurn and the handleTimelineTick change so a reader diffing the description against the diff doesn't go looking for a method that isn't there.
