F Divine super combat potion(4) — persistent 300gp+ post-tax spread, 2,000-unit cycle killed

DSCP(4)'s market has a persistent ~200-500gp post-tax spread across the 48h block-average window; PvMers and herblore crafters trade on disjoint cadences, so a patient flipper collects the full buy limit (2,000) twice a day. Daily close drift is -1.5% over 21 days — survivable for a 4h hold.

Entry: Place buy offer at 18,268 gp (current low leg) for 2,000 units.
Exit: List sell offer at 18,985 gp (current high leg; net post 2% GE tax = 18,605, but the spread is the post-tax margin reported by the system = 338 gp).

Kill switch: live margin below 200gp for 2 consecutive 4-hour cycles (would indicate the structural spread is gone)
