Neutral infrastructure primitive
Verifiable receipts for digital actions.
Digital Action Receipts (DARs) are issued at the moment an action occurs and preserved as append-only, tamper-evident records. They provide a durable reference to what happened—before disputes, audits, incident reviews, or narrative reconstruction.
Orientation
What DAR is
A small, durable artifact that proves an action occurred. DAR records facts, not interpretations.
What DAR is not
Not monitoring. Not dashboards. Not policy enforcement. Not a compliance product. It preserves evidence.
Why it exists
When systems are questioned later, mutable logs and narratives fail. DAR provides a stable reference that survives remediation and hindsight.
How DAR fits into existing systems
DAR is designed to be added with minimal coupling: issue a receipt where an action is committed; store it append-only; verify it later by reference. It complements logs and observability by preserving an immutable anchor for the most consequential actions.
- Write-heavy, read-light: optimized for issuance at scale and verification on demand.
- No runtime ML inference: receipts are evidence artifacts, not predictions.
- Neutral boundary: provides proof of action without becoming the arbiter of disputes.
Action Domains
DAR applies wherever digital actions can be questioned later. These domains describe common patterns—not limits. Each domain is defined by the action surface and the evidentiary questions that follow.
Action Proof & Non-Repudiation
Prove an action occurred at time T, by actor A, against object O—verifiably and durably.
Access & Control Decisions
Record authentication/authorization decisions and boundary enforcement under a policy context.
State Transitions
Infrastructure/config changes: preserve what was applied, when, and by whom—without rewriting history.
Autonomous & Agent Actions
Record agent tool calls and delegated actions for accountability without surveillance or interpretation.
Dead-simple integration (concept)
Engineers should be able to add DAR in minutes: issue a receipt at the action boundary and attach a stable reference.
