Mark a moment

Mark before reproducing

Open Logs → Console and press Mark immediately before the action you want to investigate:

1. Clear your mental starting point by pressing Mark.
2. Reproduce the tap, navigation or flow in the app.
3. Read the entries captured after the marker.
4. Open Timeline on the Mark row when the interaction crosses modules.

The boundary uses the device sequence number, not only the clock. Several entries can share a millisecond; the marker still separates the earlier stream from the new one.

Earlier events stay available

By default, the stream hides the entries before the Mark so the new behavior has room to speak. The earlier context is not deleted. Expand it when the setup, previous request or initial state matters.

The marker row tells you how much earlier context is hidden and gives you a direct Timeline action. Removing the Mark returns the stream to the full retained history.

Mark is forward-looking

A Mark answers: “What did my action cause?” Its Timeline window starts at the marker and follows the events that came after it. A log, error or failed request answers a different question — “What happened around this exact event?” — so those anchors show context before and after.

This distinction keeps the same Timeline useful for both reproductions and post-failure analysis. Read Timeline for the shared model.
