One template (every routed expert at five bits, E4M3 scales in 64-groups, the
top level rotated through the 128-wide Hadamard chosen by GPTQ against CALIB)
plus a driver that generates the per-arm expert row, so the other 60 lines can
never drift between arms: control (cd=3), cd=6, and act_order=1 with NO cd= -
libquant refuses the pair (lq_registry.cpp:105), so the AoA arm is its own
sweep, not a fourth column.
The header carries the campaign's order (fetch -> build reference -> one drained
window for the calibration tap and the KLD reference -> trash the bf16 container
-> imatrix -> arms -> fetch the FP8 anchor last -> gate -> trio edit), because
that sequence is point-of-use for whoever runs it next, and the disk sequencing
is forced: 754 GiB free does not hold checkpoint + reference + three arms.
Gates that bite before 5h13m of convert time is spent: the BF16 reference still
occupying the volume, a recording too thin to be a calibration (converting
uncalibrated is silently worse and only whispers on stderr), an imatrix outside
the mounted campaign dir, an arm that already exists, a protected derivation
that cannot land its target, and a destination that cannot hold the output. Each
arm runs --plan-only first so the engine's own fit check bills at plan time; the
served container's argv shape is what the arms declare.
