Municipal Risk Events & Controls

RISK EVENT
Permit Submission / Fee Payment
FAILURE MODE
Impersonation, altered documentation, disputed timing
MODULE CONTROL
Security Sandbox + signed receipts + Arweave anchoring
MUNICIPAL OUTCOME
Non-repudiation: who / what / when provable during appeals
RISK EVENT
Inspection Sign-off / Milestone Approval
FAILURE MODE
Deepfake voice/video approval, coerced sign-off, later denial
MODULE CONTROL
Liveness + voice/prosody checks; policy-gated approvals; canary rollout
MUNICIPAL OUTCOME
Reduces fraudulent approvals; enforces repeatable authorization
RISK EVENT
Dispute / Audit / Public Records Request
FAILURE MODE
Missing logs, tampered records, inconsistent versions
MODULE CONTROL
IPFS content addressing + Arweave permanent anchoring
MUNICIPAL OUTCOME
Audit-grade chain of custody; evidentiary integrity survives vendor change
PILLAR 01

Security Sandbox

Dedicated adversarial testing allocation runs impersonation attempts, replay attacks, privilege escalation, and workflow bypass probes before deployment with hard health thresholds.

PILLAR 02

Arweave Anchoring

Evidence artifacts are content-addressed via IPFS then permanently anchored to Arweave. Municipal systems store only hashes and transaction references, keeping PII exposure minimal while preserving evidentiary integrity that survives any vendor change.
