Abstract
The wood of the pau-brasil tree (<em>Paubrasilia echinata</em> Lam., formerly <em>Caesalpinia echinata</em> Lam.) is used worldwide as raw material for the construction of high-quality bows for string instruments. Alternative tree species are rarely accepted by professional musicians, or by bow and violin makers. Historical overexploitation of this endemic species in the Brazilian Atlantic Forest biome (Mata Atlântica), a global biodiversity hotpot including UNESCO World Natural Heritage Sites, and illegal trade have caused drastic declines in its natural abundance. Pau-brasil is now classified as an endangered species and listed in Appendix II of the Convention on International Trade in Endangered Species. Traditional bow-making craftsmanship, an intangible cultural heritage, depends heavily on the high-quality pau-brasil wood. This complex situation presents unprecedented cross-continental transdisciplinary challenges. In order to target the protection of this coupled natural/cultural heritage, this work frames and examines the pau-brasil/bow-making cultural-ecological system as a complex telecoupled system linked by cultural ecosystem services provided by the pau-brasil, as well as the relationships and cultural exchanges among key actors. Using historical trajectory analysis, we identify past, present, and potential future trigger events, key drivers, and key system variables that explain the dynamics, feedback, and resilience of this complex multi-dimensional system. Furthermore, with a cross-scale social and power relations analysis, we examine the level of dependencies and influences of contemporary key actors on the ecosystem services provided by the pau-brasil and their interconnections, in order to ultimately identify their level of disadvantage regarding the pau-brasil. Finally, we discuss the potential of this novel cultural-ecological system approach to (i) interlink science, nature, and art, (ii) reconcile the currently competing protection aims of natural and cultural heritage elements, and (iii) provide future trajectories regarding the resilience and sustainable development of this pau-brasil/bow-making cultural-ecological system. We advocate for this novel path forward toward sustainable transformation of complex cultural-ecological systems urgently needed to navigate our increasingly telecoupled world.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
