The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Field tests demonstrate a collar recognition F1 score of 98.6% at a throughput of 1000 Sa/s. Notably, the algorithm requires only 1.5 μs per sample, confirming its computational efficiency and suitability for deployment on resource-constrained, high-temperature downhole platforms.

C2weakest assumption

The physical plausibility verification rules remain effective and general across varying well conditions, interference levels, and casing configurations beyond those encountered in the reported field tests.

C3one line summary

The DTPPMP system achieves 98.6% F1 score in collar recognition for self-locating perforating at 1000 Sa/s using dynamic threshold and physical plausibility algorithms that run in 1.5 μs per sample.
