Actionable now — latest run, live-checked against current prices

Camphor repair kit sustains a ~33gp post-tax spread at full 4h buy limit (13,000 units) because camphor-log supply sets the floor and high-level smithing/construction demand keeps the sell side liquid; the spread has held ≥50% of current width in 71% of the last 24 hourly buckets — a standing spread, not a one-print spike — and the 30-day daily-close range (1,500–1,850) is flat enough that the sell leg does not get eaten by drift.

Kill switch: Live quote() shows margin_persistence_24h below 0.4 OR high_age_s above 600s for 3 consecutive checks OR vol5m_total(1h) below 1,000 for 3 consecutive checks.
