[#2, #3, #4, #5, #6, #7, #8, #9, #11, #19, #21] Environmental chamber, UPS/generator purchase, vibration & seismic sensors, sound monitoring/logging, active isolation platform, multiple secondary chilled/soundproof storage units, remote handling systems, directed cold-air suppression hardware, initial PPE procurement, transport crate/vehicle retrofit, media-monitoring tooling. Estimates are summed as capital hardware purchases.

[#1] Lead- and sound-proofed containment safe construction and structural reinforcement, gasketing, certification, and installation labor.

[#15, #17] High-fidelity audio capture hardware and initial secure data/telemetry servers, recording infrastructure and initial setup for analysis.

[#27] Marginal one-time per additional SCP-1493 unit (storage + handling + minor equipment) to allow rapid scale-up if multiple new instances are discovered.

[#24] One-time hazardous-materials handling / lead disposal / insulation replacement costs expected over useful life (initial allowance).

[#12, #13, #21] Security personnel (3 FTE guards, rotation) and scientific staff (1 senior researcher + 1 technician) and one media/monitoring analyst; salaries/benefits make up the majority of recurring expense.

[#21, #22] Media monitoring, tip processing, analyst follow-up, cover operations reserve, and legal/public-safety mitigation contingency (PR, legal, buyback operations).

[#15, #16, #17, #26] Outsourced imaging and per-scan budgets, software licenses/compute for audio analysis, secure data storage maintenance, and a funded long-term research program for psychophysical testing and signal analysis.

[#25] Administrative, compliance, program management, audits, insurance-equivalent and 15% contingency applied to direct recurring costs.

[#7, #19, #20] Running costs for secondary chilled storage units, per-transfer transport operations, and a field-retrieval / recovery team budget for rapid-response missions and travel.

[#3, #4, #5, #6, #18, #24] UPS/generator fuel & maintenance, vibration sensor recalibration, sound system calibration, active isolation service contracts, periodic replacement of interior soundproofing/foam, annual hazardous-materials handling allowance.

[#14] Annual emergency response training and simulation costs for subduing emergent instances and breach drills.

[#8, #9, #10, #11] Consumable soft-manipulator pads, cryogen/gas supplies and spare parts, general consumables for suppression and small PPE replacements.

[#27] Recurring per-additional-unit monitoring/maintenance cost (estimate per discovered extra unit).

[#23] Regular hearing tests, psychological screening, and occupational health monitoring for staff.
