# Are GP_DIALOG entries 0/1 and 2/3 language pairs or duplicates? 2026-08-31.
# ✅ ANSWERED, and the two cases SPLIT.
#
# They are the only two adjacent pairs in GP_DIALOG with identical element sets;
# every other adjacent pair is two unrelated dialogs
# (difficulty-is-a-dialog.txt). Identical element NAMES are equally consistent
# with a language pair and with a byte-for-byte duplicate, so it was left
# untested. The bytes decide it.
#
# ✅ CONTROL: entries 10/11 are known to be two DIFFERENT dialogs (stage 10 vs
# stage 02). They differ in 54.90 % of the common prefix and in size. A
# comparator that cannot separate two unrelated dialogs cannot judge two similar
# ones -- this one can.
#
#   entries 10/11  sizes 7 072 448 / 6 788 820   54.90 % of bytes differ
#   entries  0/1   sizes    59 810 /    59 810    0.00 % -- BYTE-IDENTICAL
#   entries  2/3   sizes 8 136 936 / 8 124 856    2.77 % differ, first at 0x1BB
#
# ✅ ENTRIES 0/1 ARE A DUPLICATE. Same size, zero differing bytes. Not a language
# pair -- the same 59 810 bytes stored twice.
#
# 🟡 ENTRIES 2/3 -- THE DIFFICULTY BUILD -- ARE NOT. Different sizes, 2.77 % of
# bytes differing from offset 0x1BB, while sharing EVERY element name. That is
# what a language pair looks like: one layout, one element set, and a small
# fraction of the payload differing where the glyphs live.
#
# ⚠️ SUPPORTED, NOT PROVEN, and the untested step is nameable: I have not
# captured DIFFICULTY in `ja`. What is established is "two builds, same element
# names, ~97.2 % identical bytes"; that they are ENGLISH and JAPANESE rests on the
# disc's pattern of shipping screens twice per language, not on a capture of this
# screen.
#
# 📌 This partially restores a claim I withdrew. I called 2/3 "an EN/JP pair" as a
# bare assertion, and withdrew it when sylpheed-port showed adjacent GP_DIALOG
# entries are generally unrelated. The withdrawal was right -- I had no evidence
# then. This is the evidence, and it is weaker than the original phrasing: a pair
# by structure, a LANGUAGE pair by inference from a disc-wide convention.
