[#1, #2, #4, #5, #14, #20, #21, #30] Deep-sea site construction, limited tunnel/shore integration, two coastal outpost capital, Faraday cage/chamber structure, contaminated-artifact handling facility setup, life-support initial installation, medical clinic setup, and initial decommissioning capital reserve.

[#31] One-time secrecy and covert operations surcharge (applied as ~30% of capital costs to cover black-budget premiums, expedited clandestine logistics and overruns).

[#3, #6, #7, #12, #15, #16, #23, #26] Deep-submergence docking/hangar and mother-ship hardware, power generation capital (generators, batteries), super-computation/AIC containment hardware, non-wireless/EM-safe tooling procurement, initial instrumentation, EMP generator procurement, initial data-storage hardware, and initial specialized alloy/parts stockpile.

[#27, #30] Initial research lab buildout and instrumentation specifically for SCP-9400-H studies and initial neutralization/decommissioning R&D infrastructure.

[#8, #4, #6, #20, #14, #15, #5, #16] Continuous hull/pressure maintenance, coastal outpost upkeep, power-system maintenance/fuel, life-support operations, contaminated-artifact facility operations, instrumentation calibration/monitoring, Faraday certification, and EMP system maintenance/testing.

[#31] Recurring secrecy/black-ops surcharge (~30% applied to recurring operational costs for covert logistics, bribery, expedited clandestine services and likely overruns).

[#24] Annual allocation to a contingency/black-budget reserve for catastrophic remediation, large-scale denial operations and emergency response.

[#17] Continuous 500 m exclusion enforcement: patrol vessels, covert surveillance ships, rapid-response craft and clandestine maritime operations.

[#30] Ongoing R&D allocation toward long-term neutralization or decommissioning research and preparatory studies.

[#27, #23, #22, #29, #7] Ongoing SCP-9400-H research teams and experiments, data archival/storage maintenance, regular training/drills and contingency exercises, continuous background reinvestigations/record-keeping, and AIC/supercomputing operational costs.

[#9] Salaries, hazard pay and retention for permanent on-site complement (scientists, engineers, security, medics, pilots, AIC team, admin).

[#28] Annual set-aside for evacuation, displacement, compensation and environmental cleanup contingency.

[#3, #19] Submersible operations and docking, regular resupply (food, fuel, spare parts), medevac and transport between shoreheads and Site-537.

[#18, #25] Covert operations budget for misinformation/bribes/chart alteration and legal/diplomatic liaison costs with local governments.

[#12, #13, #26] Replacement/recertification of non-wireless equipment, replacement/disposal of contaminated/manual cutting tools, and spare specialized parts/alloys consumption.

[#21] On-site medical clinic running costs, emergency care, mutation monitoring, and medevac readiness (consumables and staffing portion).

[#10] Costs to maintain, rotate, medically screen and replace on-site D-Class personnel (housing, restraints, medical checks, logistics).

[#11] Mandatory psychological screening, weekly counselling, rotation medicals and long-term care budgets for staff exposed to SCP-9400-H effects.
