jtbl and o0 are held out of the default lane because a draft cannot BANK without
tooling first (a rodata carve; an -O0 object, and no Makefile glob matches md_* at
all). 'cc1' is not that: it records that some earlier draft failed to compile. A
compiling draft banks through the normal splice->build->SHA path regardless of its
history, and a non-compiling one fails fast at cc1 for the price of one build.

Holding 14 groups / 105 instances / 6,511 ins out of every wave bought nothing.
Effective on the next wave draw (build_wave_atlas is a fresh subprocess per draw —
no lane restart needed).
