moby_anim: the class table is not the loader

Ruled out the cheap approach: moby_classes (offset 0xc0, count 238 in level 0)
holds float-shaped values, and only 120 of the first 4,096 u32s land inside the
overlay .text against ~259 expected by chance. Fewer than chance, so the loader
is not dispatched from a pointer here.

Not concluded what the 238 entries are -- the float reading is suggestive but was
taken at one stride on one level.

+## moby_anim: the class table is not the loader (negative result)
+
+`moby_anim` needs the moby class loader. The obvious place to look for a loader
+is the moby class table, since a loader is usually dispatched from one. Checked
+that first and it is ruled out.
+
+`moby_classes` is an `ArrayRange`: offset `0xc0`, count 238, in level 0. The
+words there are not pointers. Read as floats they are
+
+    0x4846a9e3  0x47f40000  0x46d0b0de   ->  ~50,986   61,000   26,671
+
+which is position/scale-shaped data. And scanning every u32 in the first
+`0x4000` bytes for values landing inside the overlay's `.text`
+(`0x2a3b80..0x447900`) gives **120 hits out of 4,096**, against roughly **259**
+expected if the values were unrelated to the region.
+
+So the table holds *fewer* .text-range values than chance, not more. Whatever the
+moby class loader is, it is not dispatched from a pointer in this table.
+
+That rules out the cheap approach. Finding the loader means cross-referencing
+from somewhere else -- most likely a constructor that reads the class table and
+returns runtime state, which is in `.text` and has to be found by scanning for
+code that touches both `moby_classes.offset` and the class spans. That is a
+larger search than a bounded probe, and it is the unblock condition already
+recorded for `moby_anim`.
+
+Not concluded: what the 238 entries *are*. The float reading is suggestive, not
+established -- it was read at one stride, on one level, and rule 3a applies.
