[#1, #2, #7, #30] Structural construction and hardened containment: Site modification for A/B, portal chamber excavation/vault work and any tunneling/subterranean conduit; includes reference to initial-startup summary.

[#3, #6, #11, #12, #15, #16, #20, #24] Hardware purchases and heavy equipment: reality-anchor hardware (hardware portion), mapping drones/tethers, machine-shop tooling (CNC/3D printing/welding rigs), redundancy stockpile of components, transport vehicles, sensor suites, and one-time emergency/medical equipment; heavy-lift crates/crane rentals included here where equipment-like.

[#18] One-time emergency repair fund / contingency reserve to seed rapid-response contracting and large emergency works.

[#28] Reserve for future decommissioning / safe mothballing (one-time contingency reserved up-front).

[#5, #13, #26, #27] Conservation lab buildout and research infrastructure: bronze/steel conservation work, compute/modeling servers and simulation software, R&D for neutralization/countermeasures (one-time R&D), and archival/catalog infrastructure.

[#4] One-time cost per controlled relocation/thaumaturgical campaign to move/bind the portal (specialist thaumaturges, rare reagents, site prep).

[#19] Upfront legal/cover-story/OPSEC expenditures (diplomatic fees, falsified records, relocation compensation) incurred during relocation and initial cover-up.

[#8] Controlled demolition of original Knossos entrance, debris removal, archaeological salvage and cover-up/falsified records (one-time).

[#6] Specialized covert relocation logistics (special crates, vibration isolation, climate-controlled transport, convoy security) distinct from vehicle procurement.

[#9, #10, #11, #15] Salaries for security staff (guards & supervisors), specialist research staff (thaumaturgists, archaeologists, engineers, liaison/legal), and on-site medical/psych support; includes shop staffing.

[#23, #29] Long-term research funding and program costs into SCP-6403 abilities, prototypes and contractor grants; tied to the analyst annual ballpark operational estimate.

[#21] Insurance-equivalent / indemnity/diplomatic fee reserve and legal contingencies (annual budgeted equivalent).

[#4] Recurring cost for periodic re-bindings or relocation rituals if required (specialist teams & consumables).

[#18] Annual replenishment to maintain the contingency/emergency reserve after drawdowns.

[#25] Psychological operations, staff rotation costs, counseling, hazard leave and retention differentials for Fourth House program personnel.

[#3] Maintenance, calibration and power conditioning for reality‑anchoring / Hume damping hardware (recurring calibration & service).

[#17] Ongoing maintenance of containment structures, HVAC and environmental control systems; baseline facilities upkeep and minor structural repairs.

[#12] Consumables and disposable/damaged drones, tether replacements and expendable mapping hardware used in exploration ops.

[#19] Ongoing PR, local government relations, media management and occasional cover-up expenditures.

[#14] General consumables for exploration and maintenance (batteries, lubricants, welding gases, spare sensors, ritual reagents, disposables).

[#20] Recurring transport/convoy operational costs (charters, armored convoy ops, crane rentals on ops).

[#24] Maintenance and replacement of multi-spectrum cameras, Hume gauges, seismic/magnetometer arrays and recorders.

[#13] Ongoing operations for data storage, compute, software licensing, backups and offsite replication.

[#15] Ongoing machine-shop operational costs, raw material stocking and technician hours for automaton repairs.

[#22] Regular training, drills and certifications (non-Euclidean navigation, hazmat, ritual safety, remote-ops).

[#26] Readiness and maintenance for neutralization/containment equipment and countermeasures (recurring readiness).

[#5] Ongoing monitoring and periodic conservation for bronze/iron automatons (climate-control, inspections, corrosion inhibitors).

[#27] Ongoing archival, cataloging and cultural heritage handling costs.
