The census filtered pak entries whose own first four bytes are T8aD. A sprite
is usually a child of a RATC bundle, and a bundle entry's magic is RATC, so a
top-level magic filter cannot see one:
top-level T8aD entries (counted) 4 525 sprites, 45 keys
T8aD inside RATC bundles (missed) 16 659 sprites, 204 keys
both 21 184 sprites, 216 keys
171 of the 216 keys exist only inside bundles. The sharpest statement of the
error: that census never saw GP_TITLE.pak at all -- the pak holding both of the
screens this page's entire evidence comes from.
Retracted: "45 values", "the keys are pak-local", "each auxiliary pak occupies
its own narrow high-byte band". On the full population 68/216 keys (31%, not
9%) cross a pak family and the per-pak ranges overlap heavily -- GP_BUNK
0x8000-0xa110, GP_TITLE 0x8000-0xc150, GP_LEADERBOARD 0x8000-0xf100. The tidy
banding was an artifact of seeing one or two keys per pak. So the key looks
like a shared vocabulary, which is the opposite of what I published.
Survives, now on the full population: the field is a u16 at +0x0A (upper half
zero 21 184/21 184), and it is an enumeration (216 values for 21 184 sprites).
Three wrong numbers on this page now, all the same shape -- a statistic computed
over a population I had not checked was the population in question. Stated once
at the end of the section rather than three times: check the sampling frame
before the statistic.
