The IGLN gold-sleeve 'priced but no order' bug. scaled_weights sizes orders to the paper envelope (envelope*within_weight), but _plan's entry-floor/hysteresis threshold used entry_floor*nlv (the full $1M account NLV) — so the effective floor was ~entry_floor*(nlv/envelope) of the envelope (~5%), silently dropping every sleeve below it. A 3% gold sleeve at a $100k envelope on a $1M account skipped. FIX: rebalance_weights takes sizing_capital (the envelope); the floor is entry_floor*min(sizing_capital,nlv). Sizing + recording unchanged. Regression test: a 3% sleeve survives WITH the envelope basis, drops without it. 2005 green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
