Delete the fourth interruption and let the continuing background show through. Resolve it to its stable ID from the current event inventory, remove only that event instance, and keep e3's new timing and second-channel lag. Verify preservation outside the deleted event's support with CompareFunctionStudy, inspect the recovered region, and retain the deleted revision in history. Explain the result briefly.

AI4

Deleted the fourth interruption, e4 (1985–2215 s), in activated revision r7-ebc54198e3ae.

Inspected the recovered region: the continuing background now shows through on all three channels, replacing e4’s pulses and hold.
e3’s timing and 6-second peak y lag remain unchanged, as do all other events.
CompareFunctionStudy measured zero maximum and RMS difference outside e4’s support, across 168,500 samples per channel.
Kotlin compilation passed. The pre-deletion revision r6-deb1b1738cb0, containing e4, remains in history.
