Research direction
No source files, tests, or entry points are named. Reproduce the issue during a thunderstorm with a piston lightning rod and a trident, then trace the POI data handling associated with the reported BlockPosition. Done means the reproduction no longer emits the repeated “POI data mismatch: never registered” error.
