# CIS-2 conformance vector: attention_block_v1
# op=attention_block, spec ref: docs/CIS2_SPEC_v0.2.md §9.2 (Score), §9.3
# (Softmax), §9.4 (V-mix) -- one query head's full score/softmax/V-mix
# pipeline against a small causal KV cache. Deliberately covers ONE head
# only: GQA's `kv_head = qh / group` head-mapping (§9, opening paragraph)
# is a pure indexing detail on top of this same per-head arithmetic, not
# additional numeric behavior, so it is not separately vectored here.
# RoPE (§7, already covered by rope_v1) is assumed already applied to
# `q_head`/`k_j` inputs below, per §9.1's ordering (RoPE happens before
# scoring) -- this vector starts from already-rotated q/k, as the spec's
# §9.2 step itself does.
#
# Fields are `key=value`. `head_dim`/`seq_len` are plain decimal integers.
# `q_head_bits` is head_dim values (the current step's query head, already
# RoPE-rotated). `k_bits`/`v_bits` are `seq_len * head_dim` values,
# ROW-MAJOR (cached key/value at position 0's head_dim entries, then
# position 1, ... up to and including the current step `pos = seq_len -
# 1`, causal -- every cached position is attended, per §9.2's `j =
# 0..=pos`). All comma-separated `0x`-prefixed 32-bit hex IEEE-754 binary32
# bit patterns, per tests/conformance/README.md's general convention.
