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

DeepCS-TRD achieved the best automatic detection performance, with an F-score of 81.0% and precision of 86.4%. Automatic detection reduced the required manual correction effort to approximately 20% of ring boundaries. For one-dimensional ring-width measurements, TRAS showed excellent agreement with CooRecorder (r > 0.99).

C2weakest assumption

That the 18 expertly annotated Pinus taeda L. cross-section images are representative of the variability in tree ring images encountered in practice, and that manual corrections via the interface are sufficient to produce scientifically reliable outputs without introducing systematic biases.

C3one line summary

TRAS integrates CS-TRD, DeepCS-TRD, and INBD detection methods with an interactive GUI, achieving 81% F-score on 18 Pinus taeda images while reducing manual correction to ~20% of boundaries and matching CooRecorder ring-width measurements at r > 0.99.
