Why h is special: Of all 26 letters, the two forms of italic 'h' are the most visually distinct. Form a has an open counter — the arch rises and returns, leaving clear daylight between the arch and the right leg. Form b has a closed counter — the arch comes down and encloses the space, creating a shape that resembles italic 'b'. This is the primary diagnostic letter for the entire cipher.
Form a (LC1) — as it appears in text
h
Open arch · standard italic h
Form b (LC2) — the alternate form
b
Closed arch · resembles italic b
Diagnostic window for h — arch/counter junction
Examine only the space between the arch apex and the right leg. Is there open daylight? → Form a. Is the counter enclosed into a rounded bowl? → Form b. This is the single most reliable classification in the entire cipher.

Open counter — clear space visible between arch and right leg
The 'h' in "The" has the open arch form. Matches LC1 (Form a).
Note: this same 'h' appears as Form b later in the Prologue — e.g. line 21 "their high" — demonstrating the deliberate alternation that encodes the cipher.
