Every tool call goes through the same 4 operations — stamp, verify, export, search. Here is what that means in practice depending on your context:
Automated trading / finance Any agent that submits orders, rebalances portfolios, or triggers transactions can stamp each decision before execution. The signed chain is exportable for SEC/FINRA audit without any additional infrastructure.
HR and hiring automation Any workflow that evaluates candidates, scores CVs, or routes applicants can stamp each decision. Provides a GDPR Art.22 compliant audit trail for AI-assisted hiring — who decided what, when, and what data was used (hashed, never stored raw).
Content and publishing pipelines Any agent that drafts, approves, or publishes content can stamp each step. Useful when multiple AI agents collaborate and you need to prove attribution — which agent wrote what, in what order.
DevOps and CI/CD Any agent that triggers deployments, merges branches, or rotates secrets can stamp each action. Provides a tamper-evident record of infrastructure changes made by autonomous agents.
Healthcare and medical AI Any diagnostic or triage agent can stamp each recommendation. Provides a HIPAA-compliant audit trail linking each AI output to a verifiable agent identity.
The common pattern in all cases:
[Agent makes decision]
↓
piqrypt_stamp_event ← sign + chain
↓
[Agent executes action]
↓
piqrypt_export_audit ← portable proo
