The question, scope, and sources behind this Registry record.
Maximize energy inside a finite time interval among unit-energy signals bandlimited to [-B,B].
Current frontiers derived from accepted Claims.
The accepted equality closes this optimization result.
Assertions tied to evidence, attribution, and review.
The frontier as it changed over time.
Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
