pub const MEGABUF_SLOTS: usize = 65_536;Expand description
How many slots a preset’s megabuf holds.
EEL2’s reference megabuf is 8 388 608 slots, which at f32 is 32 MB per
preset — by a wide margin the largest memory number Plan 0100 could
introduce, and one that would be allocated whether or not a preset touched a
single slot. The corpus census says only 4 % of it (435 of 10 347 files)
mentions megabuf or gmegabuf at all.
So the arena is sized from what the corpus plausibly uses rather than from the
reference: 65 536 slots, 256 KB, allocated once per loaded preset and never
grown. An index outside it reads 0 and writes nowhere — total, like every
other edge here.
This is a number with a shelf life and a named successor. Plan 0100
Phase 5’s --report runs the converter over the corpus and ranks the failure
classes; a preset whose megabuf addressing runs past this appears there by
name rather than silently rendering wrong. Raise it from that evidence, not
from a hunch.
