This document defines a governance profile for structuring mobile location records and en-route warnings, enhancing safety and incident review in various contexts.
This document defines TSUMS Field Evidence Chain v1.0, a public-layer governance profile for structuring mobile location records, GPX traces, and en-route warning events into a replayable field evidence chain. It provides public field names, warning categories, governance-state labels, replay mapping fields, privacy boundaries, and a hypothetical scenario for use in mountain safety governance, incident review, civil field operations, institutional audit, and disaster risk reduction contexts. This profile does not disclose TSUMS core scoring algorithms, internal weights, operational thresholds, enforcement logic, financial pricing logic, or rescue decision rules. It does not function as a tracking application, surveillance system, rescue command protocol, legal liability engine, insurance denial tool, or government procurement specification. The principle is: Black box closed. Evidence chain open.
