# Execution Timeline (Console)

> How the workflow run Timeline tab visualizes step durations, agent activity, and loop iterations.

# Execution Timeline

The **Timeline** tab in the workflow execution panel (Workflow Studio → open a run → **Execution panel** → **Timeline**) shows a Gantt-style view of step durations in execution order. It's a duration-first companion to the **Events** tab — the same run activity, laid out on a timeline instead of a log.

## What Timeline shows

### One row per step

Every step in the run gets a row: its name as the label, and a bar spanning from start to end (or to "now" while it's still running). Bar color matches the step's status, using the same colors as the Events tab.

### Agent activity sub-rows

Steps of type `agent_call` show nested child rows for what happened during that agent's turn:

| Activity      | What it shows                                                              |
| ------------- | -------------------------------------------------------------------------- |
| Tool round    | Each round of tool calls, labeled `Round N · tool` with a summary on hover |
| Status change | Phase transitions during the turn                                          |
| Limit reached | A marker when the turn hits its configured tool-round limit                |

### Composite loop segments (`for_each` / `while`)

For loop steps, Timeline shows estimated iteration segments once the loop completes — collapsed by default, expandable with the chevron on the parent row. Segments are marked as **estimated** until precise per-iteration timing is available, at which point they become exact.

### Run state markers

Vertical colored lines mark run-level state transitions (paused, resumed, failed, stopped) so you can see at a glance where in the timeline the run's state changed. Hover a marker for the transition and timestamp.

### What's not shown

* Generic, non-step platform events (these stay on the Events tab)
* Steps with no agent activity just show as a single bar — there's nothing to expand

## Context tab — execution graph

The **Context** tab includes a static preview of the run's step graph. Click **Open graph** for an interactive modal where you can pan, zoom, and click a step to focus it on the Workflow Studio canvas.

Edges are styled to distinguish workflow wiring from execution-order fallbacks and from loop-body steps, so you can tell at a glance whether an edge reflects your graph design or the actual order steps ran in.
