# CIS-2 conformance vector: exp_pinned_v1
# op=exp_pinned, spec ref: docs/CIS2_SPEC_v0.2.md §6.2 (pinned exp(x)
# polynomial, route (b) fallback described in src/math.rs::exp_pinned).
#
# Fields are `key=value`. x_bits is a comma-separated list of
# `0x`-prefixed 32-bit hex strings, each the raw IEEE-754 binary32 bit
# pattern of one input element, in index order (index 0 first).
#
# n=8, deliberately small and hand-sized (same rationale as rmsnorm_v1's
# n=8 / rope_v1's head_dim=8), spanning §6.2's documented accuracy domain
# `x in [-40,40]` (softmax post-max-sub args <= 0, SiLU gate args, RoPE
# inv_freq exponents): the two domain endpoints (-40, 40), a couple of
# mid-range values on each side (-10, -1, 10), the two special values
# 0.0 and 1.0 (exp(0)=1 exactly is a useful bit-exact sanity check), and
# 0.5 to exercise a non-integer, non-zero small positive value.
