 spectral_profile.py — 8D Spectral Profile from Byte-Level Co-occurrence Statistics
 
-Computes an 8-dimensional spectral profile from the raw byte structure of an
-equation string. Uses ONLY byte-level co-occurrence statistics — no semantic
-parsing, no tokenization, no NLP.
+⚠️  DISCONNECTED FROM LEAN PIPELINE — This module computes a byte-level
+spectral profile that is NOT used by the formal SilverSight system.
+The Lean PIST pipeline uses 8×8 braid adjacency matrices from
+rrc_pist_predictions_250_v1.json, not byte co-occurrence profiles.
 
-The 8 dimensions are derived from the byte co-occurrence matrix C where
-C[i,j] = count of byte i followed by byte j (with wrap-around).
+Retained for experimental/Python-side use only.
