Values are midpoints aggregated.

[#7] One-time recruitment/premium/background-check costs for baseline hires (Senior Researcher + 3 handlers assumed) at midpoint per-hire.

[#16] Initial trauma kits and training setup (midpoint of $5k–$20k).

[#14] Small one-time administrative/contract-setup fee related to explosive ordnance disposal contractor engagement.

[#5, #6] Senior Researcher (midpoint $150k) + 3 dance-qualified handlers (midpoint $80k each) = $390k/yr (fully loaded estimates).

[#11, #13, #18] Ongoing sensor calibration & data storage ($2k–$10k), degradation/kinetics research programs including assays/GC-MS ($50k–$200k), and secure recordkeeping/transcription ($3k–$12k). Values aggregated.

[#17] Legal retainer ($25k–$100k/yr midpoint) plus an annual cover-up/PR budget for minor disclosure mitigation (~$50k/yr). Contingency reserve for catastrophic events is captured as one-time above.

[#14] Annual retainer for certified explosive ordnance disposal contractor ($10k–$50k/yr midpoint). Per-incident disposal costs are modeled in scenarios.

[#22] Psychological care and ethics oversight for staff interacting with sentient explosives ($10k–$40k/yr midpoint).

[#25] Overtime, temp hires, or travel to ensure dances occur within required intervals ($5k–$30k/yr midpoint).

[#8] Annual dance/safety recertification and balance training for handlers (aggregated $5k–$20k/yr midpoint).

[#12] Monthly inspection direct labor (~12 hrs/mo at blended $50–$80/hr) plus admin overhead; represents hands-on inspection/harnessing/dance labor outside base salaries estimate.
