re: record the disc-side corroboration as a separate quantity, and the log-line substitution

sylpheed-port checked the JP layout from their export: the disc declares identical
button rows for EN and JP on main_menu and extras. Recorded separately rather than
merged with mine, because they are different quantities -- their rows are declared
rest positions, my 225.5 is a runtime ring row on a surface offset ~65 px from
design space. Either could have disagreed, which is what makes them independent
legs, after a week of finding legs that were not.

Neither is evidence for GP_DIALOG 2/3; both are about GP_TITLE.

Also records the mid-run substitution: I diagnosed a detector failure from a log
line showing glyph 11654 when the capture was one read away and showed the detector
working. A log line is a summary someone wrote, and reading it as the observation is
the same substitution as trusting a harness note.

+# ✅ INDEPENDENTLY CORROBORATED FROM THE DISC -- and the legs really are
+# independent this time, which is worth stating after a week of finding they were
+# not. sylpheed-port, from their export:
+#
+#   main_menu / main_menu_jp   button rows 162, 242, 322, 401, 482 -- identical
+#   extras    / extras_jp      button rows 282, 362, 442           -- identical
+#
+# ⚠️ THESE ARE NOT THE SAME NUMBER AS MINE, and that is the point. Their rows are
+# the DISC'S DECLARED REST POSITIONS; my 225.5 / 385.5 are RUNTIME RING ROWS in a
+# capture, on a surface offset ~65 px from design space. Different instruments,
+# different quantities. Either could have disagreed -- the disc could declare
+# identical JP rows while a runtime ring landed at 225.5 for some other reason,
+# or the disc could differ while the ring happened to match.
+#
+# So, stated separately rather than merged into one claim:
+#   * THE DISC declares identical button rows for EN and JP, on two screens;
+#   * THE RUNNING JP MENU's ring sits where the English one's does.

+# 📌 Neither statement is evidence for GP_DIALOG 2/3. Both are about GP_TITLE.
