F Mahogany repair kit — thin but persistent ~30 gp spread on a high-volume construction commodity killed

Mahogany repair kit sustains a 20–59 gp hourly spread (and 13–34 gp daily) because fletcher supply from construction-contract completions (POH, Mahogany homes) dumps at the GE floor and steady refurnishing demand lifts the sell side. The 30-day closes oscillate in a tight 1,034–1,156 band with a 5% width, so the hold is survivable even when the spread is thin. Vol24h of 456k makes 11,400 units/4h at 15% participation very achievable, and the post-tax margin of 30 gp clears the 200k floor at full size.

Entry: Place buy offer at 1,043 gp, 13,000 units, refresh each 4 h cycle when margin ≥ 25 gp.
Exit: Sell instantly at 1,094 gp (or higher) for any fill; convert buy fills to sell offers same cycle.

Kill switch: A sustained 24 h close below 1,000 (below the 30 d range floor), OR margin collapses below 15 gp for 2 consecutive evaluations, OR a construction-game update re-prices the item. Kill_price 1,000 protects against single-day dislocations; standing down occurs on kill hit.
