The swift15 rule (top 7% by imatrix energy, bar-only) left the plane size to the
distribution. The w5nl64 arm trades a *pinned host pool* against KL, so the
operator needs to say how many GiB of bf16 experts the pool can afford and have
the set land there: --target-count walks the ranked candidates until the byte
bill matches, keeps the bar-only pass for experts that are disproportionate for
their size, and reports the pool's ceiling instead of padding when the count
cannot be reached.
TP=2 cuts the expert plane into two 256-expert rank halves, and an odd count in
either half unbalances the placement, so the parity audit is a refusal (exit 2,
'PARITY LAW BROKEN'), not a silent fix-up: the driver stops rather than
converting a payload whose expert placement no one priced.
apply-protected-cast.sh splices derive-protected-experts.py output into
the recipe's PROTECTED-BEGIN/END section (refuses to re-derive, trashes
the pre-edit recipe). kld-gate-swift15.sh boots the candidate on the
serving pin in --kld-ref mode (pool fully resident, no disk tier) and
enforces mean KL<=0.03 / top-1>=95% from the JSON report.
