\node[row] (m) {\textbf{Layer 1: 25 Structural Meters}\\[-1mm]
\scriptsize Local activations such as conclusion-first pressure, assertion density, evidence tokens, causal markers, emotional charge, agency transfer, and judgment delegation. These are not risk labels; they are structural reactions.};

\node[row, below=7mm of m] (b) {\textbf{Layer 2: 7 Structural Bundles}\\[-1mm]
\scriptsize Premise/Assertion, Evidence/Authority, Causality, Framing, Modulation, Emotion/Sensitivity, and Agency/Delegation/Omission. Bundles reorganize local signals into discourse-level functions.};

\node[row, below=7mm of b] (p) {\textbf{Layer 3: 5 Pressure Dimensions}\\[-1mm]
\scriptsize PREM, FLOW, FRAME, LOCK, and NOISE. Pressures describe how discourse arranges premises, causal direction, framing, closure, and reception load.};

\node[row, below=7mm of p] (u) {\textbf{Layer 4: UI4 Projection}\\[-1mm]
\scriptsize PREM / FLOW / FRAME / LOCK are rendered as human-readable structural states. The system does not output verdicts; interpretation remains with the human verifier.};
