The count description claimed every count must be "positive integral", which is wrong: zero is context-dependent. Verified at HEAD — an array dimension (`[0]s64`) and a generic value-param count (`Box(0)`, $N:u32) both accept zero as a length-0 instantiation, while a `Vector` lane count stays strictly positive (`Vector(0,f32)` rejected). Negatives are rejected for array dims and unsigned value-params, but a signed value-param accepts a negative; only the integral requirement (folds 4.0, rejects 4.5) is common to all three. Split the count paragraph into per-consumer bullets stating the exact range each accepts. Range-bound paragraph unchanged. Pin the zero contrast with examples 0147 (array-dim + value-param zero accepted) and 1505 (Vector zero-lane rejected). No compiler-code change.
