[#1, #2, #3, #11, #16, #17, #22] Includes construction of the 4m³ hermetic steel chamber, two-stage airlock and gowning, cleanroom-grade HVAC installation, decontamination shower installs, backup power install (generator/ATS), security infrastructure hardware, and site power/grounding/faraday/fit-out upgrades. Estimates are aggregated midpoints of provided ranges.

[#4, #5, #6, #7, #8, #10, #13] Includes one-time purchase/installation of air-purification systems (electrostatic precipitators), capacitor bank/high-voltage pulse system, embedded fiber-optic imaging array, data acquisition servers and infrastructure, environmental/electrostatic sensors, initial set of BSL-4-style suits and lockers, and clean handling toolkits. Values are mid-range aggregated estimates.

[#18] One-time purchase of breach mitigation equipment, portable EM-disruption devices, vacuum suit spares, initial PPE caches, and emergency planning equipment and capital fund (midpoint estimate).

[#14] Purchase and bench fit-out for microscopy and micro-mechanical testing (basic bench microscopes, micro-tensile tester). High-end SEM/TEM is assumed contracted rather than purchased in baseline; this line is for on-site lab instrumentation.

[#20] One-time legal/cover paperwork, initial permits, and costs to establish cover-story/secure leasing or black-budget setup (midpoint of 10k–50k range).

[#9] Annual salaries + benefits for containment & research staff (example staffing used: 1PI, 2 research technicians/engineers, 2 containment technicians, 2 security officers with benefits/overhead ~25–35%). Aggregate is midpoint of analyst range.

[#6, #7, #8, #14, #23, #25] Ongoing costs for instrument calibration and maintenance, data storage/backup/IT support, environmental/electrostatic monitoring calibration, contracted SEM/TEM/time for advanced analyses, long-term archival storage, and programmatic research budget.

[#20] Annual legal counsel, compliance costs, cover operations and discretionary black-budget concealment expenses (midpoint of wide analyst range).

[#21] Administrative, accounting, HR, and insurance/reserve costs (midpoint estimate from analyst range).

[#11, #12, #13, #15, #19, #24] Consumables including decontamination chemicals, particulate stock procurement & sterile packaging, sealed handling consumables, routine research consumables, hazardous-waste disposal contracts, and spare parts/consumable reserves.

[#3, #4, #5, #16, #17] Recurring maintenance for HVAC/HEPA filter replacement, air-purification system maintenance, periodic testing/maintenance of the capacitor/pulse system, generator fuel & maintenance, and security system upkeep.

[#18] Annual drills, training, and readiness exercises for emergency response teams; recurring PPE replacement for caches.
