[#1, #4, #6, #7, #11, #14, #15, #16, #26, #28] One-time procurement of hardware: SIGINT lawful-intercept kit and lawful/legal setup, HPC/signal-processing cluster (secure room/racks), safehouse/field ops assets and vehicle gear, initial tactical/MTF equipment kits, armored transport vehicles/secure crates, antenna hardware, secure data infrastructure, cover-company/office setup costs, exotic/custom hardware procurement, and low-end placeholder for space-program contingency hardware.

[#3, #9] One-time research/lab buildout: medical/xenobiology laboratory equipment and imaging; optional construction of a dedicated radio array (radio telescope array) if chosen (flagged as high-cost escalation).

[#3] Optional dedicated radio-telescope/array construction (listed separately from contracted observing time due to very large capital cost if pursued).

[#28] Low-probability, high-cost program-level contingency for space-based engagement/mission-scale actions; included as a one-time optional escalation placeholder (order-of-magnitude).

[#8, #13, #14, #29, #30] One-time construction and structural work: secure containment wing, optional underground holding site buildout, Faraday cage/EM hardening installation (structural), secure archival vault setup, and per-site decommissioning/demolition costs. Estimates use low-to-mid ranges for modest secure wing and minimal underground option plus vault/decommissioning.

[#12] One-time initial contingency reserve allocation (minimum reserve kept available; larger uses would be charged as incurred).

[#7] One-time purchase of specialized raiding hardware and per-MTF equipment kits (armored breaching gear, NVGs, restraints).

[#15] One-time secure on-premise/offsite encrypted storage and air-gapped backup infrastructure costs (initial setup).

[#16] One-time costs to create shell entities, initial office leases and legal setup for covert covers and asset acquisition.

[#6] One-time procurement for safehouses, vehicles, and evidence-gathering gear for on-the-ground investigations.

[#3, #5, #17, #27] Recurring costs for contracted radio-telescope observing and analysis time, xenolinguistics/signal research team salaries and operations, multi-year FTL signalling research program baseline funding, and external grants/academic contractor stipends under NDA.

[#10] Recurring personnel costs for core staff (loaded wages, benefits, hazard pay).

[#8, #13, #14, #29, #20] Recurring maintenance, utilities, HVAC redundancy, negative-pressure suites, Faraday/EM system upkeep, vault operations, and general site upkeep.

[#2] Recurring lease time for hosted payloads and ground-station slots to monitor wideband signals and backhaul intercepted data.

[#12] Annual allocation to maintain a rapid-response contingency reserve for immediate quarantines, evacuations, or containment-scale operations.

[#16, #24] Ongoing legal counsel, cover-company operational expenses, payouts/bribes, settlements, and PR/media suppression budgets for plausible deniability.

[#6] Ongoing covert surveillance, informant payments, undercover field investigators, stakeouts, and travel to locate SCP-2775-1 facilities.

[#23] Recurring indefinite housing, medical treatment, enrichment, and security for retained humanoid specimens (assumes a small cohort).

[#7] Average expected annual spend on planning and limited tactical deployments (assumes <1 major raid per year averaged over time).

[#22] Recurring cross-border interdiction, covert payments, customs workarounds and cooperative operations for international shipments/interdictions.

[#9, #19] Lab consumables, PPE, sterilants, decontamination supplies, reagent replenishment, waste disposal.

[#11] Recurring base costs for charters, fuel, drivers and pilots for routine specimen and staff transport.

[#1] Recurring operational licenses, maintenance, telecom payments, and covert operator salaries for regional lawful intercepts (cellular, VoIP, IMSI-catchers).

[#4] Power, maintenance, software updates, and UPS/room upkeep for on-premise HPC/signal-processing cluster.

[#15] Annual costs for encrypted long-term storage, transcription/redaction services, offsite backups, and archival migrations.

[#25] Recurring training, drills, accreditation, and safety audits for containment teams and analysts.

[#18] Ongoing psychological support, vetting, polygraphs, and counterintelligence programs for staff.

[#21] Recurring evidence processing and forensic cataloguing costs to maintain chain-of-custody and forensic readiness.
