v3.11.6-rc.15 (audit H-1) — how many fan-out sub-queries run concurrently.
Bounds the simultaneous full pipelines (graph-boost / optional reranker /
embedding) so a legal 9-phrasing request can't start 9 heavy pipelines at
once on the event loop. Combined with the buildTfidfIndex single-flight
(which collapses the shared corpus BUILD — the expensive read+tokenize scan,
the H-1 amplifier — to ONE regardless), this bounds the worst-case cold
fan-out cost. Same-scope calls that overlap also share discovery/cache
validation; each query still performs its own terminal generation admission
because its candidate/snippet work can finish at a different time.
