Restore the background

The original exchange, including tool results and plot images. Expand tool activity to inspect the steps; open a plot to see it full size.

You

Restore the previous unwarped background, but keep all current event timings, e3's second-channel lag, and the deletion of e4. Use the historical source as a reference and create a new checked revision, not a rollback that loses the event work. Compare the result against the revision just before the background warp and demonstrate equality over the whole hour. Show the current overview, and give a concise summary of what this conversation has preserved.

Restored the unwarped background in r9-82456e1e48ac, a new checked child of r8—not a rollback. I used historical r7-ebc54198e3ae to restore direct absolute-time background evaluation.

Whole-hour equality

Compared against pre-warp r7 with no channels allowed to change: - 180,001 samples per channel, covering 0–3600 s at ≤20 ms spacing plus event joins. - Maximum error: 0; RMS error: 0 for x, y, and z. - No event metadata differences.

The overview above also overlays r7 exactly at the sampled points. Kotlin compilation passed.

Preserved through this conversation

e3: start 1425 s, 200-second rise, shared all-ones hold 1625–1655 s, end 1755 s.
e3’s y lag: 6-second peak, smoothly recovered by 1605 s.
e4 remains deleted, revealing the continuing background.
e1, e2, e5, e6 retain their timings and stable IDs.
All five 30-second holds remain intact.
Revision history retains both the background-warp experiment and the version containing e4.
