Primary metric
hf_kv_slot_rank1_count = 1 / 3
Verdict: REFUTE H-KV — the hypothesis does not survive. Reason: C2 rank-1 count (1) < 2 (threshold).
Sanity guard: C0 baseline
C0 ranks: [8605, 5048, 158] C0 far-from-1 check: PASS (all ranks > 10)
C2 injection latency (ms)
Mean: 183.89 ms Median: 185.64 ms Range: 159.76 – 206.26 ms
Secondary: splice position (exploratory)
