cadence: one-vendor-per-slot round-robin — fix stuck cursor (idx pinned at 0 ran Thibaut every slot)

1590533f4f346ddb674ea48cca42e28c9d15a9de · 2026-06-23 10:06:03 -0700 · Steve Studio

The old advance (start+picked.length)%ready.length wrapped a full lap back to the
same start whenever VENDORS_PER_SLOT >= READY count (live --vendors 8 vs 6-7 READY),
pinning idx at 0. Now clamp per-slot picks to leave room to advance and step the
cursor by picked.length so every slot leads with the NEXT READY vendor and wraps.
Runner: --vendors 1 --skus $MAXP (Steve: every 18/hr should be a new vendor).
