The hooked and static writes kept one op per site, so two ops on one layer steered with the last alone. The ops at a site now compose in order; a static site of plain adds takes their sum. Co-authored-by: Cursor <cursoragent@cursor.com>

vLLM kept only the last steer op per site (hooked and static). Ops at a site now compose in order, matching eager.
Tests: CPU parity in
