[#2, #4, #5, #7, #8, #9, #11, #14, #18, #19, #21, #27, #15] Elevator control hardware/firmware, environmental sensors/cameras/servers, initial PPE reusable respirators, initial stock of replacement face-plates, remote/robotic inspection units, precision bulb-breaker tools, ERT weapons/armor/radios, containment crates and secure vehicle procurement, archival conservation hardware, AV/forensics hardware, and sound-mitigation hardware.

[#12, #13, #22, #28] Research lab buildout and BSL-2/3 upgrades (autoclaves, chemical benches), initial laboratory instrumentation and setup, spill kits and emergency neutralization gear, and a modest contingency budget for possible large-volume specimen/material removal campaigns.

[#1, #3, #10, #20] Structural containment envelope and access hardening (elevators/airlock/anterooms), ballistic/safe-firing corridor construction and sound/holding-suite buildout; includes vaulting of Floor 24 entrance, negative-pressure vestibule construction, airlock installation, and a set of 4 specialized holding suites.

[#11, #12, #18] ERT salaries for an 8-person rapid-response team (~$440k/yr), research team salaries for 5 specialists (~$675k/yr), and logistics/clerical staff (2 FTE, ~$100k/yr).

[#12, #14, #22, #23, #27] Ongoing chemical/biological assay reagents and consumables, secure data storage & CCTV/audio maintenance, behavioral research trials and oversight, AV forensic analysts and related monitoring budgets, and minor R&D for sound mitigation.

[#26] Amortization/replacement reserve estimated at ~7% of initial capital equipment/facility value (applied to one-time capital ~ $2.88M).

[#30] Flexible discretionary R&D for unforeseen anomalous behaviors, rapid prototyping, specialist consults, and emergent containment technical development.

[#5, #9, #17] PPE/disposable masks program and/or consumable respirator filters (~$120k/yr), precision-tool consumables/ammo for bulb-breaker tools (~$6k/yr), and decontamination consumables/laundry (~$37k/yr).

[#16, #29] Occupational health program, regular medical screenings, on-call medical coverage, casualty care readiness, and psychological support/counseling for exposed staff.

[#25] Annual full-scale breach exercises and incremental reservation/contribution toward an on-hand contingency fund for medium incidents.

[#10, #11] Firearms/marksmanship training (if authorized), ERT recurrent certification, and other skills maintenance.

[#1, #2, #3, #4, #8, #10, #11] Annual upkeep of structural containment envelope, elevator/electronics support, HEPA filter replacement and airlock upkeep, environmental system calibration, robotic maintenance, and upkeep of ballistic/shield installations and related infrastructure.

[#24] Budget for cover stories, legal counsel, reimbursements, and limited local authority mitigation to preserve secrecy.

[#13, #28] Annual hazardous-waste disposal contracts and small-volume remediation for black paint/canvas-like plant matter; larger removal campaigns budgeted as one-time events.

[#21] Ongoing translation support, paleography consultations, and archival conservation upkeep for recovered French documents and Document-1619-8.

[#20] Operational costs for specialized long-term holding suites (utilities, UV scheduling, minor repairs).

[#6] UV bulb parts and replacement labor: assumed ~25 active SCP-1619-2-C instances at roughly $1,500/instance/yr (bulbs + swap labor). Scale-linear to instance count; note originally gave $720–$2,280/instance/yr.

[#18, #19] Inventory system maintenance and vehicle/transport maintenance and fuel for secure returns and routine logistics.

[#7] Ongoing replacement parts for protective face-plates and custom machining; initial stock bought up-front and annual small replacement budget assumed.
