TCT defines a deterministic JSON representation at a machine-facing URL, bidirectional discovery between human-facing and machine-facing resources, JSON sitemaps containing representation-validator hints, and conditional request behavior using ordinary strong ETags. TCT preserves standard HTTP validator scope: an M-URL ETag identifies the exact selected M-URL representation. Optional Semantic Validators can correlate the logical state of human-facing and machine-facing representations, but are not required by TCT and do not replace ordinary cache validators. TCT does not define authorization, licensing, content-use policy, or mutation semantics.}, }
