Audit Architecture

Executive Summary

Audit Architecture defines how Algosure records material actions, access, decisions, approvals, events, AIOS activity, integration activity, security decisions, and administrative changes.

Why This Exists

Algosure must support accountability for procurement workflows, compliance evidence, bids, contracts, funding, payments, AI recommendations, tenant access, and platform administration.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Auditability supports trust, compliance readiness, dispute resolution, security investigation, AI explainability, and executive accountability.

Audit records are tenant-scoped	Audit review must respect tenant isolation and administrator policy.
Audit records do not expose secrets	Tokens, passwords, API keys, private credentials, and raw secrets must not be logged.
Audit supports correlation	Audit records must connect to events, requests, approvals, and AIOS reasoning where relevant.
Audit is tamper-resistant by design	Audit records should be protected from unauthorized modification.
