It is covered by 13 and it is excessive (especially having to retain a k-5.6) but you’ll still have to include all in the calc. When using the full design area (no reductions for QR etc so 1500 sf for LH wet and 1950 for LH Dry etc) you can omit form the calculation sprinklers in closets and similar small rooms. You can omit including the sprinkler under obstructions and calc just the one at the ceiling (but it is considered to have 2 sprinklers covering the same floor area). Although the area of coverage is very small and your overage is VERY high, you still have to include all sprinklers within the remote area except as identified above.
Your only prayer is the AHJ providing an allowance due to the unique of the situation combined with them requiring a minimum K-5.6. Good luck.
