F Ruby necklace F2P post-tax spread flip vetoed
vetoed at ship time: claimed per_cycle_gp 414000 exceeds 2x the live recomputation 0 (margin -10 x 18000 fillable units)
Ruby necklace sustains a 23–24 gp post-tax spread on 1.2M vol24h because F2P gem-cutters and Crafting hunters dump at market while completionists and re-cutters pay the top of the bid. 18k buy limit × 24 gp = 432k post-tax per cycle at FULL size — the 50M budget is not the constraint. The spread is small per unit but the volume is so large that even patient fills escalate to a meaningful daily gp. 48h 15-min buckets show a 20–30 gp spread reprints every block, killing the snapshot-only objection. 30d daily closes range 1045–1095 (flat), qualifying as Band-B-stable.
Entry: place buy offer at 1070 (or +1 tick under current low)
Exit: place sell offer at 1115 (or -1 tick under current high)
Kill switch: Live margin drops below 10 gp on a quote inside the freshness gate; or 21d daily close prints below 1020 (band floor breach).
