This document defines TSUMS Green Carbon Governance Tier v1.0, a public-layer governance profile for carbon integrity, ecological risk signals, disturbance and reversal records, community governance signals, and replayable nature-based accountability. The profile structures carbon and ecological claims into traceable, replayable, risk-aware governance records for public reference, institutional review, governance comparison, policy discussion, climate-risk learning, audit support, and independent citation. It establishes a public-layer interface for reviewing carbon integrity claims, ecological risk signals, monitoring records, community safeguards, accountable roles, required records, replay outcomes, and divergence types without converting the framework into a certification, enforcement, or pricing mechanism. This document does not certify carbon credits, determine land rights, issue ESG ratings, price carbon assets, replace MRV authorities, authorize carbon markets, adjudicate legal claims, or function as an enforcement mechanism. It does not disclose TSUMS core scoring formulas, internal weights, proprietary MRV algorithms, operational thresholds, carbon pricing logic, enforcement logic, or land-right adjudication logic. The principle is: Green carbon is not only stored carbon. It is stored responsibility. Black box closed. Integrity interface open.
