pub const EXECUTOR_BACKING_DEFAULT_U64S: usize = _; // 11_071usizeExpand description
The reservation’s size when nothing overrides it: one default-sized executor’s worth.
One executor, not a multiple, because an entry opens ONE through this road:
a tiered boot’s SPAWNED tiers take their slots from the entry’s own
TierExecutorBacking instead (issue 1571), each slot this many words.
Named by the GENERATED file when nothing overrides the size, so it is unused
under NROS_EXECUTOR_BACKING_U64S=0 (no static) and under an explicit
override (a literal). Kept rather than cfg’d: it is what the override is
judged against, and a constant that disappears with its consumer cannot be
compared to anything.
