SCP-4087 Euclid ~ medium confidence

Absence of a Knife

Expected annual

$19.4M

One-time setup

$211.5M

Annual recurring

$18.8M

Personnel

Baseline operations require on the order of tens of millions per year, driven primarily by embedded law-enforcement assets, analytics staffing, and field response teams; one-time capital risk (notably potential new DGR construction) can push costs into the hundreds of millions.

🏗️ One-Time Capital Costs Total: $211.5M

New Dgr Construction Capex $200.0M

[#8] Capital cost for constructing a new dedicated deep geological repository (range $50M–$500M; mid chosen)

Contingency Seed Fund $10.0M

[#16] Seed contingency / emergency response reserve (one-time seed between $5M–$50M)

Equipment $975K

[#2, #4] Initial secure compute cluster and field response equipment/armored vehicle purchases (compute cluster ~$350k + vehicles/kits ~$625k)

Initial Research And Lab Setup $300K

[#2, #13, #14] Initial lab/medical room buildout and setup for analytics, memetic/amnestic interventions, and R&D

Cryptographic Archiving Systems $100K

[#19] One-time secure logging/HSM/air-gapped archive systems (range $20k–$200k)

Heavy Transport Per Instance Estimate $50K

[#7] Representative per-instance heavy-transport/airlift equipment cost estimate (per-instance range $5k–$500k)

Facilities $30K

[#11] Interim secure vault & cataloging setup (one-time evidence-vault installation and setup)

Tamper Evident Block Design Certification $18K

[#6] One-time certification/design cost for tamper-evident reinforced concrete block design (~$10k–$25k per new design)

🔄 Annual Recurring Costs Total: $18.8M/yr

[#12, #20] Ongoing PR/legal team, cover-story maintenance, redaction/legal operations and compensation programs

Contingency Replenishment $1.0M/yr

[#16] Recommended annual replenishment for contingency/emergency reserve

Logistics And Transport $900K/yr

[#7, #20, #3] Annual logistics program for cross-border coordination, per-incident transport budgets, travel allowances for field teams

Facilities Maintenance $165K/yr

[#4, #9, #11, #19] Maintenance and replacement for field equipment/vehicles, DGR/vault systems upkeep, interim vault operations, and archive system maintenance

Supplies And Consumables $115K/yr

[#5, #18] Per-incident forensic lab consumables/contracts and PPE/decontamination/waste-disposal recurring costs

Concrete Casting Materials $50K/yr

[#6] Recurring per-instance materials/mold amortization for casting concrete blocks (assumes ~10 castings/year at mid-range)

Dgr Operation $3K/yr

[#8] Marginal annual monitoring/storage fee if using existing Foundation DGR capacity (low-end marginal cost)

⚡ Cost Scenarios

📊 Baseline (baseline) $18.8M/yr

82.9% probability / year

Routine year with no major incidents: ongoing monitoring, analytics, embedded assets, routine transports and a handful of flagged investigations.

no major exposures typical incident rate (~10 flagged instances/year) use of existing DGR capacity

🚨 Minor Incident $19.4M/yr

15.0% probability / year +$600K vs baseline

One or a few higher-cost incidents requiring extra transport, legal response, and targeted amnestic/forensic campaigns.

3–5 cross-border recoveries several high-profile legal challenges expanded per-incident forensic work

🚨 Major Breach $33.8M/yr

2.0% probability / year +$15.0M vs baseline

Significant containment failure or public exposure that triggers large amnestic campaigns, emergency logistics, and sustained legal actions.

large-scale public exposure international legal/political fallout emergency DGR expansion or rapid mass amnestics

🚨 New Dgr Construction $218.8M/yr

0.1% probability / year +$200.0M vs baseline

Decision to build a new dedicated DGR for long-term SCP-4087 storage, incurring major one-time capital expenditure.

policy decision to centralize anomalous storage existing DGR capacity exhausted strategic long-term isolation requirement

📋 Confidence Notes

Analyst-provided ranges and explicit line-item estimates allow a reasoned mid-range budget, but many items (embedded asset counts, incident frequency, and potential new DGR build decisions) are uncertain and scenario-dependent, so confidence is medium.
