[#21] Budget set aside for potential major civil-engineering containment upgrades (subsurface seals, grout walls, deep excavation). High uncertainty; cost reserved as a one-time contingency pool.

[#2, #4, #6, #7, #8, #11, #15, #17] One-time hardware/equipment purchases and installs: fence power/control and backup equipment, mobile incineration vehicle(s) and response kits, surveillance/CCTV towers, subterranean drone fleet and docking/repair bays, subsurface sensing array hardware, initial emergency decon/autoclave kit, transport fleet (ground vehicles and helicopter), and secure communications/IT hardware.

[#22] One-time reserve fund allocation for accidents, legal settlements, catastrophic asset replacement and rapid escalation response; intended to be replenished as needed.

[#1, #13, #16, #14] Perimeter fencing installation, land purchase, site housing construction, and initial permitting/mitigation costs for wildlife/environmental compliance; includes signage, animal-exclusion measures, dorm/food service construction and permitting work.

[#9] Initial high-containment lab fit-out (BSL-3 baseline fit-out chosen for startup): construction, HVAC, autoclaves, negative-pressure suites and basic lab instrumentation to allow necropsy/analysis while limiting initial capital outlay vs immediate BSL-4 build.

[#13] Initial legal, PR and cover-story setup costs (licenses, initial counsel, cover-company establishment, initial local government coordination and permit application support).

[#19] Initial stock of PPE, filters, sterilants, sampling kits, batteries and fuel stores for startup operations.

[#20] One-time development of training curricula, drills design, and initial psychological-support program setup.

[#5] Permitting and setup costs for hazardous waste handling and ash testing (initial fees, containment planning, permit applications).

[#3, #10, #11] Salaries, benefits and overtime for continuous security staffing (perimeter patrols & gatehouses), research personnel and technical staff, and emergency medical/decon staffing.

[#9, #8, #10] Recurring non-payroll research budgets and lab operating costs (BSL lab operations excluding salaries), subsurface data processing/monitoring, and project budgets for long-term study of Echidna Events.

[#15, #4, #5] Recurring vehicle operations, helicopter operating/lease costs, hazardous material transport fees and routine fleet maintenance.

[#4, #5, #7, #19, #11] Recurring consumables: incinerator fuel/maintenance, hazardous ash disposal and lab testing transport, drone spare parts and consumables, PPE replacement and sterilization supplies, and medical supplies for decontamination.

[#22] Annual replenishment budget to maintain the reserve fund after use or to grow contingency reserves over time.

[#2, #6, #16, #14] Ongoing maintenance for fence power/control systems and UPS/generator upkeep, surveillance system maintenance and operators, site housing upkeep, and annual environmental compliance costs.

[#18] Electricity, heating and generator fuel for continuous fence energization, labs (including HVAC loads for containment), charging drone fleets, and data centers.

[#13] Ongoing legal counsel, PR/cover-story maintenance, payments or agreements with local authorities and routine coordination costs.

[#20] Recurring drills, exercises, specialized incineration/containment training, and psychological support/counseling programs for staff.

[#17] Recurring secure-communications, cybersecurity, bandwidth, and secure data storage/backup services for LiDAR, geophysical and biological data.

[#12] Recurring procurement/replenishment of amnestic-grade pharmaceuticals and sedation supplies, plus clinical oversight costs for administration.
