A char is spent only on a column that actually occurs. Fold reserves 2^K. This table is the typeface.
Stackpack tile 200×1. Each glyph is one distinct column, one bit per row, depth = number of scanlines. AUTOFAB0 on the full 102,925 B file measured 48 distinct of 4,117 deep (cite 07). Published SEED0 is in this repo so every participant can draw a live table. Drop any bytes to see that file's alphabet.
Do not field-narrow the unused 2^K. They were never spent. stackpack.py stays the CLI. Width is 200.

Each column is one glyph. White = 1 down the depth. SEED0 at 200×1 spends a char on almost every column — little structure. DISTRO and AUTOFAB0 spend fewer. That is C as weather, drawn.
